Macharia,  Peter Masinde,  Joyce Aswani,  Anselmy Opiyo MEDICOM The African Journal of Hospital and Scientific Medicine, (2010) Vol  25: 33 - 36 Abstract Head and neck cancer occupies over 50% of in-patient beds at the Ear, Nose and Throat-Head and Neck Surgery Unit of the Kenyatta National Hospital. Laryngeal cancer is the third most common head and neck cancer after nasopharyngeal and oral cancers. Aim: To determine the demographic features, symptomatology, morbid anatomy, histology and disease stage of laryngeal cancer, and to assess the efficiency of the hospital facility in coping with initial work-up and diagnosis of the patients with laryngeal cancer from 1996 to 2001. Setting: Department of Ear, Nose and Throat/Head and Neck Surgery at The Kenyatta National Hospital Study design: Retrospective review of case notes of 100 patients admitted to the unit between 1996 and 2001. Results: Male to female ratio was 24:1. The peak age at presentation was 50 to 70 years with a mean of 60.6 years. Duration of delay between onset of symptoms and presentation to the unit was 4 to 300 weeks with a mean of 50 weeks. Long history of hoarseness of voices and respiratory stridor were the most frequent symptoms. Preoperative tracheostomy rate was 81%. Vocal cords were involved in 54% of cases, 33% supraglottic, 6% subglottic and 7% indeterminate. Delay in obtaining histological results after biopsy ranged from 1 to 71 days with a mean of 43 days. Ninety five per cent of cases had various grades of squamous cell carcinoma. GI differentiation was found in 36%, G2 in 25% and G3 carcinomas involving the vocal cords tended to be well differentiated.

As part of a study to assess zoonotic milk-borne health risks, seasonal survey data and unpasteurized milk samples were collected between January 1999 and February 2000 from randomly selected informal milk market agents (220 and 236 samples in the dry and wet seasons, respectively) and from households purchasing raw milk (213 and 219 samples in the dry and wet seasons, respectively) in rural and urban locations in Central Kenya and screened for antibiotics, Brucella abortus (B. abortus) and presence of Escherichia coli (E. coli 0157:H7).The latter was assessed based on samples from consumer households only. Antibodies to B. abortus were screened using the indirect antibody Enzyme Linked Immunosorbent Assay (ELISA) and the Milk Ring Test (MRT). The presence of E. coli 0157:H7 was assessed by culture, biochemical characterization, serological testing for production of verocytotoxin one (VTI) and two (VT2) and polymerase chain reaction (PCR) analysis for the presence of genes encoding for the toxins.                                                                                                         The prevalence of antibodies to B.abortus varied considerably ranging from none in milk sold in small units and originating from intensive production systems to over 10% in samples that were bulked or originating from extensive production systems. E. coli 0157:H7 was isolated from two samples (0.8%), one of which produced VTI. All urban consumers (100%) and nearly all rural consumers (96%) of marketed milk boiled the milk before consumption, mainly in tea, thus reducing chances of exposure to live pathogens and potential health risks.

The antihypertensive effect of the fixed combination of timolol, a beta-blocking agent, hydrochlorothiazide, a thiazide diuretic, and amiloride, a potassium sparing agent, was compared against that of methyldopa in an open study lasting 16 weeks in 32 ambulatory African patients with previously untreated diastolic blood pressure of 95-120 mm Hg. A significant fall in mean diastolic and systolic blood pressure was achieved in both groups up to 8 weeks of treatment and was sustained in the timolol-hydrochlorothiazide-amiloride group during the entire follow-up. In the methyldopa group, mean diastolic and systolic blood pressure rose during follow-up. At 16 weeks the fall in mean diastolic and systolic blood pressure was significantly greater in the timolol-hydrochlorothiazide-amiloride treated patients than in the methyldopa group. Adverse reactions were more frequent and severe in the methyldopa group than in timolol-hydrochlorothiazide-amiloride treated patients. It is concluded that the fixed drug combination of timolol-hydrochlorothiazide-amiloride (Moducren) is effective in controlling mild to moderate hypertension in Africans and is better tolerated than methyldopa in these patients. It is further noted that hypertensive patients can be treated with a combination tablet once a day. This is of crucial significance as it would promote better compliance and, hence, minimize the sequelae of poorly controlled hypertension.

Forty females, age 14 to 35 years (mean 28.6 years) with chronic renal failure (CRF) were included in the study. Their menstrual patterns were noted. The function of their hypothalamo-pituitary-ovarian axis was assessed by the serum levels of follicle stimulating hormone (FSH), Luteinising hormone (LH), prolactin (PrL), estradiol (E2) and progesterone (P) at different phases of the menstrual cycle in patients who continued to have normal menses (Group 1) and at weekly intervals for six weeks in patients with menstrual disturbances (Group II). The mean hormone levels during the initial contact Luteal phase in group I were FSH 12.0 IU/L (N, 1.0-3.0 IU/L), LH 1.8IU/L (N 1.5-101U/L), PrL 652mIU/L (N, 100-600 mIU/L) mE2 160 pmol/L (N 400-1400 pmol/L) and P5 nmol/L (N 14-60 nmol/L) for group I. Corresponding values for group II were 1.2, 10.3, 250, 600 and 3.0 in relevant units. All patients (fourteen) with end stage renal disease (ESRD) had amenorrhoae. On the other hand, most patients with stable CRF (22/26) had normal menses. Following initiation of therapy (conservative or dialytic), there was no significant alteration in the hormonal profile or menstrual pattern. We conclude that other factors apart from the hormonal imbalances, may be responsible for the menstrual disturbances noted in patients with CRF.

Weights and heights of 674 consecutive non-insulin dependent diabetics and 358 control urban healthy Kenyans were recorded prospectively. Weights and heights of a further 162 healthy rural adults were compared retrospectively. The body mass index (weight/height2) of the non-insulin dependent diabetic was lower than that of the corresponding urban control subject. The body mass index of the rural folk was consistently lower than that of the urban dweller. This study concluded that obesity may not be a significant factor in non-insulin dependent diabetes in the African black.

This paper reviews clinicopathological and hematological manifestations of sickle cell anemia as seen in Kenyan children in the first decade of life. The information is based on a study of 447 patients. The findings are similar to those that are well documented from America, West Africa, and other parts of Africa. However, local variations and complications such as malnutrition and topical infections that may affect prognosis are high-lighted.

Fine-needle aspiration (FNA) is a well-recognized technique for sampling solid organs. It is used in renal transplantation to clarify the cause of a poorly functioning graft. Differential scoring techniques with respect to peripheral blood cell populations, and immunocytochemistry have been employed in this context. We describe the use of simple morphological criteria alone in renal transplant FNA. We compare these with needle biopsy and clinical parameters and show their value in the detection of active cellular rejection. Their limitations are discussed within the framework of other patterns of transplant pathology.

Australian Society for Electron Microscopy, Brisbane (1994).". In: Mountain Research and Development, vol. 8, no. 2. 2011; 1994. Abstract

The fatigue crack growth (FCG) characteristics of a cast Al-Cu alloy A206 in the T7 temper condition were studied in laboratory air at a frequency of 30 Hz and an R-ratio of 0.2. Two different (as cast) thicknesses and two different casting conditions (casting with and without a chill) were investigated with the aim of characterizing the effect of porosity on the FCG behavior. The level of porosity in each sample was determined by the point-counting method and varied from 2.4 to 4.0% before hot isostatic pressing (HIP).<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

 

The study covered both near-threshold and mid-range regimes of FCG. The results indicate that for this limited range of porosity, there exists no systematic relationship between casting conditions (i.e., chilled or non-chilled) or the as-cast thickness and the average level of porosity. However, in the near-threshold regime, the FCG resistance decreased as the level of porosity increased, while in the mid-range of FCG, the FCG rate was fairly independent of the amount of porosity.

Application of HIP led to a reduction in the porosity level from about 4% to less than 0.4%, but this was accompanied by improvement in the FCG resistance only, close to the threshold. The results are rationalized in terms of the effect of porosity on the micro-mechanisms of fatigue crack growth and the initiation of secondary cracks caused by the size, distribution and morphology, of the pores.

Department of Clinical Chemistry, Kenyatta National Hospital, Nairobi, Kenya. Analysis of eleven biochemical laboratory tests was done during an International External Quality Assessment Scheme (IEQAS) in which the clinical chemistry laboratory at Kenyatta National Hospital participated. Technicon SMA II continuous flow system was used in the biochemical analyses apart from glucose which was assayed manually by the glucose oxidase method. Using the standard deviation index (SDI), twenty six percent of the results were found to be outside the two standard deviation (2SD) limit. However, when variance index score (VIS) was used, 42% of the results were found to be outliers. Overall, our laboratory performed poorly compared to other laboratories in both the IEQAS and the United Kingdom External Quality Assurance Scheme (UKEQAS). This poor performance is attributed to the use of improper equipment which is not regularly maintained, lack of diagnostic reagents, lack of quality control (QC) materials and inadequate staff training in the field of quality control.

Although military conflicts are common on the African continent, there is a paucity of data regarding bomb-blast injuries in this region and in Kenya in particular. This paper describes the pattern of maxillofacial injuries sustained after the August 1998 bomb blast that occurred in Nairobi, Kenya. A retrospective cross-sectional study was carried out using hospital-based records of 290 bomb-blast survivors admitted at the Kenyatta National Referral and Teaching Hospital in Nairobi. Using a self-designed form to record information about variables such as the sex and age of the survivors and type of location of soft- and hard-tissue injuries, it was found that of the 290 bomb-blast survivors, 78% had sustained one or more maxillofacial injuries. Soft-tissue injuries (cuts, lacerations or bruises) were the most common, constituting 61.3% of all injuries in the maxillofacial region; 27.6% had severe eye injuries, while 1.4% had fractures in the cranio-facial region. This paper concludes that the effective management of bomb-blast injuries as well as those caused by other types of disaster requires a multidisciplinary approach. The high percentage of maxillofacial injuries confirm that maxillofacial surgeons should form an integral part of this multidisciplinary team.

Thirty children presenting with Battered Baby Syndrome over a five year period were studied retrospectively. The male:female ratio was 1:1.1. The majority (60%) were aged 0-11 months. 14 children (46%) were abandoned while six (20%) had multiple fractures, six (20%) multiple bruises and bites, and four (13.3%) had other forms of abuse. Twelve (40%) children were malnourished while eight of the babies (26.6%) were small for gestational age. Children were most frequently brought to hospital by the police or their mothers. The children were most frequently abused by their mothers either through abandonment or through physical battering. Details of mothers of the 14 abandoned children were unknown. Among the mothers of the other children, nine mothers were single, seven married and living with spouses and one stepmother. Two children (6.6%) died while the fate of two others was not known. Three children were sent home without intervention of the social worker, while twenty three children were discharged following intervention of the social worker; fourteen sent home, nine to a childrens' home and one through the juvenile court.

University of Nairobi.; 1990. Abstract
In 7 years (1981-1988) at the Kenyatta National Hospital (KNH), Nairobi the diagnosis of systemic lupus erythematosus (SLE) was made in 67 patients. In 23 of these patients lupus nephritis complicated the SLE. Lupus nephritis was diagnosed through renal biopsy, haematuria and proteinuria in urine with positive lupus erythematosus (LE) cell phenomenon. The histology found in these patients included 5 patients with minimal lesion, 7 patients with membranous, 3 with focal, 4 with diffuse, 3 with crescenteric and one with membranoproliferative glomerulonephritis. While patients with minimal, membranous and focal nephritis had general good outlook on low dose maintenance or intermittent high dose steroid therapy the others with diffuse, crescenteric and membranoproliferative nephritis had poor prognosis. Patients with diffuse proliferative, membranoproliferative and crescenteric nephritis tended to have septicaemia, pulmonary oedema, fluid overload and chronic renal failure with poor prognosis. These patients responded poorly to oral and parenteral steroid therapy whether high or low dose.

Extensive research in developed countries has established that very low birth weight (VLBW) infants are particularly vulnerable to the effects of early nutritional deficiencies. There is, however, little information from poor countries on the long-term effects of these deficiencies in such infants.

Determine the association between neonatal feeding regimens and post-discharge morbidity/ mortality and neurological abnormalities at the age of two years for a cohort of VLBW infants.

Naisho JN, Ongaya L, Musandu JO. PIP: In highlighting the role of traditional birth attendants (TBAs) in the implementation of primary health care (PHC) in Kenya, the following topics are discussed: characteristics of TBAs as reported in studies, the training program, program objectives, content, the training process, resources for training, the role of TBAs in PHC, and evaluation. The definition of midwife is given as midwives trained in a community setting to assist in delivery within the confines of accepted cultural beliefs. A study of 28 midwives from different regions in Kenya in 1980 found that most were illiterate women between 24 and 68 years olds received no monetary gain, had a variety of occupational backgrounds, and provided varying amounts of advice but little pre- or postnatal care. Almost all advised mothers to breast feed for at least 2 years. 80% of mother use TBAs for delivery. In order to minimize maternal (5-20/1000 live births on the average) and infant mortality, many countries have or are developing training programs for TBAs. Inadequacies in TBA care may be little prenatal care, too little postnatal care, and deficits in promoting child spacing; other unsafe practices may be improper washing of hands and severing the umbilical cord with unsterile objects. Other advantages of training TBAs involve less cost, less need for transportation, personalized setting in the home, source of health education in the community, and rapport with her clients. The training program goal is to reduce mortality by eliminating bad practices. The objectives are to reduce maternal deaths or illness from hemorrhage, infection, and toxemia; to encourage better nutrition; to reduce perineal or vaginal tears which may lead to longterm disability from urinary or rectal fistula; to reduce the number of pregnancies or exposure to risk; and to reduce neonatal tetanus asphyxia, infection, diarrhea, and malnutrition. Activities entail educating adolescent girls and pregnant women on menstruation and sexuality within cultural norms, prenatal care and delivery and postnatal care, maternal care, and educating mothers about personal hygiene, nutrition, child spacing, and immunization, and acknowledgement of the valuable service TBAs contribute to the community. Programs have operated for 10 years and evaluation is underway. PMID: 2630785 [PubMed - indexed for MEDLINE]

Interest in renal disease and practice in East Africa started as far back as the first quarter of this century. Work in this colonial era concentrated on establishing the existence of renal diseases and identifying the nature and incidence of these diseases. This was achieved by case identification and reporting as well as retrospective studies on post mortem and medical notes. The post independence period has not only identified the existence of even more renal diseases but also concentrated on getting a deeper understanding of the aetiology, nature, pattern, regional variations, complications and outcome of these diseases as seen in our environment. Apart from the better understanding of the prevalent renal diseases, emphasis has also been put on the expansion and delivery of renal services. Investigative and treatment facilities have been improved and a lot has been put into the training of the required local team of experts to man these services. This article reviews what has gone on in the last 70 years from the pure case-report and postmortem reports era to the era of locally available modern facilities including haemodialysis, peritoneal dialysis and kidney transplantation.

Extensive research in developed countries has established that very low birth weight (VLBW) infants are particularly vulnerable to the effects of early nutritional deficiencies. There is, however, little information from poor countries on the long-term effects of these deficiencies in such infants.

Determine the association between neonatal feeding regimens and post-discharge morbidity/ mortality and neurological abnormalities at the age of two years for a cohort of VLBW infants.

One hundred and seventy five VLBW infants were recruited over a consecutive period of one year and followed up to the age of two years corrected for gestation. With neonatal feeding regimes as the exposure variable, post-discharge re-hospitalization, mortality and Saigal and Rosenbaum's functional disability assessment scores were compared as the outcome variables.

BACKGROUND: The district hospital is considered essential for delivering basic, cost-effective health care to children in resource poor countries. We aimed to investigate the performance of these facilities in Kenya. METHODS: Government hospitals providing first referral level care were prospectively sampled from 13 Kenyan districts. Workload statistics and data documenting the management and care of admitted children were obtained by specially trained health workers. FINDINGS: Data from 14 hospitals were surveyed with routine statistics showing considerable variation in inpatient paediatric mortality (range 4-15%) and specific case fatality rates (eg, anaemia 3-46%). The value of these routine data is seriously undermined by missing data, apparent avoidance of a diagnosis of HIV/AIDS, and absence of standard definitions. Case management practices are often not in line with national or international guidelines. For malaria, signs defining severity such as the level of consciousness and degree of respiratory distress are often not documented (range per hospital 0-100% and 9-77%, respectively), loading doses of quinine are rarely given (3% of cases) and dose errors are not uncommon. Resource constraints such as a lack of nutritional supplements for malnourished children also restrict the provision of basic, effective care. INTERPRETATION: Even crude performance measures suggest there is a great need to improve care and data quality, and to identify and tackle key health system constraints at the first referral level in Kenya. Appropriate intervention might lead to more effective use of health workers' efforts in such hospitals.

Thirty eight symptomatic and two asymptomatic patients seropositive for human immunodeficiency virus type-1 (HIV-1) were treated with a natural human interferon alpha (HuIFN alpha). Patients were given 2 IU/kg HuIFN alpha orally once daily in powdered maltose held in the mouth to promote mucosal absorption. This oral immunomodulating HuIFN alpha therapy resulted in an increase in CD4+ lymphocytes, an increase in weight, and a dramatic alleviation of clinical symptoms related to HIV-1 infection.

The currently available evidence suggest that diuretics and/or low dose dopamine increases renal blood flow (RBF), glomerular filtration rate (GFR) and natriuresis in experimental animals, and limits ATP utilisation and oxygen needs in nephron segments at high risk of ischaemic injury, actions that could potentially limit renal injury and accelerate recovery in acute renal failure (ARF). These effects have indeed been confirmed in most experimental animals while using mannitol or low dose dopanime. Frusemide, however, for unknown reasons, has been effective in some animal models, but not others. In humans, it can be said that diurectics have a limited value to prevent, reverse or speed recovery from acute renal failure. Most clinical studies have failed to demonstrate convincingly that low dose dopamine either prevents ARF in high risk patients or improves renal function or outcome in patients with established ARF. This confusing scenario is further complicated by the fact that both diuretics and low dose dopamine can result in severe metabolic and cardiovascular complications in critically ill patients.

Previous observational studies in developing countries have suggested that diet quality, particularly increased animal source food (ASF) consumption, is positively associated with child cognitive development. This report presents findings from a study in rural Kenya, designed to test the impact of three different diets on the cognitive development of school children. Twelve schools with a total of 555 Standard 1 children (equivalent to U.S. Grade 1) were randomized to one of four feeding interventions: Meat, Milk, Energy or Control (no feeding). Feeding continued for seven school terms (21 mo), and cognitive tests were administered before the commencement of feeding and during every other term of feeding. Hierarchical linear random effects models and associated methods were used to examine the effects of treatment group on changes in cognitive performance over time. Analyses revealed that children receiving supplemental food with meat significantly outperformed all other children on the Raven's Progressive Matrices. Children supplemented with meat, and children supplemented with energy, outperformed children in the Control group on tests of arithmetic ability. There were no group differences on tests of verbal comprehension. Results suggest that supplementation with animal source food has positive effects on Kenyan children's cognitive performance. However, these effects are not equivalent across all domains of cognitive functioning, nor did different forms of animal source foods produce the same beneficial effects. Implications of these findings for supplementation programs in developing countries are discussed.

Two major etiological agents, hepatitis B virus and aflatoxin B1, are considered to be involved in the induction of liver cancer in Africa. In order to elucidate any synergistic effect of these two agents we conducted a study in various parts of Kenya with different liver cancer incidence in order to establish the rate of exposure to aflatoxin and the prevalence of hepatitis infections. Of all tested individuals 12.6% were positive for aflatoxin exposure as indicated by the urinary excretion of aflatoxin B1-guanine. Assuming no annual and seasonal variation, a regional variation in the exposure was observed. The highest rate of aflatoxin exposure was found in the Western Highlands and Central Province. The incidence of hepatitis infection nationwide as measured by the presence of the surface antigens was 10.6%, but a wide regional variation was observed. A multiplicative and additive regression analysis to investigate if hepatitis and aflatoxin exposure had a synergetic effect in the induction of liver cancer was negative. However, a moderate degree of correlation between the exposure to aflatoxin and liver cancer was observed when the study was limited to certain ethnic groups. The study gives additional support to the hypothesis that aflatoxin is a human liver carcinogen.

Neurological manifestations of HIV/AIDS is reviewed and discussed. It is noted that neurological manifestations are some of the commonest modes of clinical presentation of HIV/AIDS. At autopsy, the prevalence approaches 100%. These manifestations include: involvement of the higher functions, craniopathies, spinal cord disease, peripheral neuropathy and muscle disease. It is therefore stressed that the central nervous system must be particularly assessed in patients with HIV/AIDS and where the clinician is not sure of the neurological diagnosis, a referral to the neurologist is recommended as some of these are treatable

As part of a study to assess zoonotic milk-borne health risks, seasonal survey data and unpasteurized milk samples were collected between January 1999 and February 2000 from randomly selected informal milk market agents (220 and 236 samples in the dry and wet seasons, respectively) and from households purchasing raw milk (213 and 219 samples in the dry and wet seasons, respectively) in rural and urban locations in Central Kenya and screened for antibiotics, Brucella abortus (B. abortus) and presence of Escherichia coli (E. coli 0157:H7).The latter was assessed based on samples from consumer households only. Antibodies to B. abortus were screened using the indirect antibody Enzyme Linked Immunosorbent Assay (ELISA) and the Milk Ring Test (MRT). The presence of E. coli 0157:H7 was assessed by culture, biochemical characterization, serological testing for production of verocytotoxin one (VTI) and two (VT2) and polymerase chain reaction (PCR) analysis for the presence of genes encoding for the toxins.                                                                                                         The prevalence of antibodies to B.abortus varied considerably ranging from none in milk sold in small units and originating from intensive production systems to over 10% in samples that were bulked or originating from extensive production systems. E. coli 0157:H7 was isolated from two samples (0.8%), one of which produced VTI. All urban consumers (100%) and nearly all rural consumers (96%) of marketed milk boiled the milk before consumption, mainly in tea, thus reducing chances of exposure to live pathogens and potential health risks.

The antihypertensive effect of the fixed combination of timolol, a beta-blocking agent, hydrochlorothiazide, a thiazide diuretic, and amiloride, a potassium sparing agent, was compared against that of methyldopa in an open study lasting 16 weeks in 32 ambulatory African patients with previously untreated diastolic blood pressure of 95-120 mm Hg. A significant fall in mean diastolic and systolic blood pressure was achieved in both groups up to 8 weeks of treatment and was sustained in the timolol-hydrochlorothiazide-amiloride group during the entire follow-up. In the methyldopa group, mean diastolic and systolic blood pressure rose during follow-up. At 16 weeks the fall in mean diastolic and systolic blood pressure was significantly greater in the timolol-hydrochlorothiazide-amiloride treated patients than in the methyldopa group. Adverse reactions were more frequent and severe in the methyldopa group than in timolol-hydrochlorothiazide-amiloride treated patients. It is concluded that the fixed drug combination of timolol-hydrochlorothiazide-amiloride (Moducren) is effective in controlling mild to moderate hypertension in Africans and is better tolerated than methyldopa in these patients. It is further noted that hypertensive patients can be treated with a combination tablet once a day. This is of crucial significance as it would promote better compliance and, hence, minimize the sequelae of poorly controlled hypertension.

End stage renal disease requiring renal replacement therapy is a common complication of several renal diseases that are seen in the tropics. World over, the costs of the various modalities of therapy that constitute renal replacement therapy, including hemodialysis, continuous ambulatory peritoneal dialysis and renal transplantation, is prohibitive. All the above modes of therapy are provided in Kenya, unlike most countries with similar level of socioeconomic development. This article analyses the factors behind the limited success that renal replacement therapy enjoys in Kenya, which is faced with more pressing basic problems of malnutrition and infection.

Eighty-four consecutive black patients who had confirmed but untreated hypertension participated in a double-blind randomized clinical trial involving potassium supplement (64 mmol/day) versus bendrofluazide (10 mg/day). Diastolic blood pressure (DBP) of the 42 patients receiving potassium supplementation (group A) decreased from a mean (+/- SD) of 108 +/- 3 to 88 +/- 4 mm Hg (p less than 0.001; paired t test) after 28 weeks of medication. DBP of the 42 patients receiving bendrofluazide (group B) decreased from a mean of 108 +/- 2 to 84 +/- 4 mm Hg (p less than 0.001; paired t test). There was no statistically significant difference between the magnitude of decrease in DBP in group A and B patients (unpaired t test). No clinical, biochemical, or ECG abnormalities occurred in group A patients. Eight group B patients showed hyperuricemia; 4 patients in the same group had hyperglycemia and 3 other patients had hypokalemia. The results support the notion that potassium supplementation may be an effective therapeutic approach to mildly hypertensive blacks.

Sera of 95 mothers and 129 children from Nairobi, Kenya, collected in 1976, and of 466 adults and 193 children of Embu District, Kenya, collected in 1984 and 1985, were analyzed for the presence of human immunodeficiency virus type 1 (HIV-1) antibodies. Although no HIV-1 seropositivity was demonstrated by western blot analysis in both study groups, 7% of Nairobi mothers and 10% of adult females from Embu District had false positive results by enzyme immunoassay (EIA) compared with less than 1% seroreactivity rates observed in adult males and children. False positive results were not due to simian T lymphotropic virus type III (STLV-IIIAGM)/human T lymphotropic virus type IV (HTLV-IV) seropositivity. Sixty-one percent of the HIV-1 EIA reactive sera could not be explained by cytotoxic activity to lymphocytes bearing the HLA-DR4 or HLA-DQw3 phenotype. We conclude that false positive HIV EIA tests are frequently encountered in East Africa. Seroprevalence rates in rural Africa must be interpreted with caution due to the decreased specificity of HIV EIAs.

PMID: 6745138 [PubMed - indexed for MEDLINE] Juma FD, Gitau W, Bwibo NO, Gachoka C.". In: East Afr Med J . 1984 Jan; 61 ( 1 ): 32-4 . Anim. Hlth. Prod. Afr. 2008; 1984. Abstract

Despite the high frequency of sickle cell disease in Europe, the disease is poorly managed. Critical periods are the hospital stays during which the anaesthesiologist plays an important role. Understanding the molecular basis of polymerization processes of haemoglobin S can help to avoid triggering a crisis. Differentiation of the various haemoglobin phenotypes helps to estimate the individual perioperative risk. Knowledge of the patient's history and the actual haemoglobin S level facilitates general anaesthesia, surgery and postoperative care. Damage to liver, spleen, eyes, bones, lung and central nervous system increases the perioperative risk. Preoperative preparation includes early admission, intravenous volume substitution, continuing pain therapy and prophylactic antibiotic medication. General anaesthesia seems to be better for patients with a high-risk profile rather than regional anaesthesia. Careful perioperative and postoperative monitoring should allow hypoxaemia, hypovolaemia, hypothermia, acidosis and overtransfusion to be avoided. Effective pain therapy includes a combination of opioids with peripherally acting analgesia.

Pubertal growth and development were compared in 342 privileged, urban children and 347 impoverished rural adolescents from Kenya. Measurements of height, weight, upper arm circumference, and triceps skinfolds revealed marked differences between the two study groups just before the onset of sexual maturation. These differences were also found in the early stages of puberty but notable catch-up was evident throughout the later period of the maturational process. Early stages of sexual maturity were delayed by 3 yr in malnourished boys with a 2.1-yr lag in the age of onset of menarche in rural girls. Derived estimates of body fat as well as direct anthropometry revealed that the onset of puberty is not size related under the circumstances of chronic childhood malnutrition.

Information on the prevalence of hearing impairment and related ear pathologies in children in sub-Saharan Africa is scarce. A pilot study for a clinical trial of simple treatments for chronic suppurative otitis media (CSOM) in school children in Kiambu district, Kenya, provided information on the prevalence of hearing impairment and ear pathologies. Five-thousand-three-hundred-sixty-eight children from 57 randomly chosen primary schools in Kiambu district were examined. Simple otoscopy was performed by clinical officers with specialty training in ENT, and hering testing was performed by trained nurses, using a hand held field audiometer. Microbiological specimens were obtained from those children with CSOM. Five-point-six percent of the children had a hearing impairment of > 30 dB HL in one or both ears, with 2.2% having bilateral hearing impairment. Two-point-four percent had at least one perforated tympanic membrane, and 1.1% had CSOM. Eight-point-six percent of the children had wax obstructing the tympanic membrane. There is evidence of a relationship between hearing impairment and both CSOM and wax obstructing the tympanic membrane. The most common organisms found were Pseudomonas spp. (34%), Proteus spp. (34%) and Eschericia coli (19%). These results are comparable with other studies in Africa and indicate a considerable burden of ear disease in Kiambu district, Kenya.

As part of a study to assess zoonotic milk-borne health risks, seasonal survey data and unpasteurized milk samples were collected between January 1999 and February 2000 from randomly selected informal milk market agents (220 and 236 samples in the dry and wet seasons, respectively) and from households purchasing raw milk (213 and 219 samples in the dry and wet seasons, respectively) in rural and urban locations in Central Kenya and screened for antibiotics, Brucella abortus (B. abortus) and presence of Escherichia coli (E. coli 0157:H7).The latter was assessed based on samples from consumer households only. Antibodies to B. abortus were screened using the indirect antibody Enzyme Linked Immunosorbent Assay (ELISA) and the Milk Ring Test (MRT). The presence of E. coli 0157:H7 was assessed by culture, biochemical characterization, serological testing for production of verocytotoxin one (VTI) and two (VT2) and polymerase chain reaction (PCR) analysis for the presence of genes encoding for the toxins.                                                                                                         The prevalence of antibodies to B.abortus varied considerably ranging from none in milk sold in small units and originating from intensive production systems to over 10% in samples that were bulked or originating from extensive production systems. E. coli 0157:H7 was isolated from two samples (0.8%), one of which produced VTI. All urban consumers (100%) and nearly all rural consumers (96%) of marketed milk boiled the milk before consumption, mainly in tea, thus reducing chances of exposure to live pathogens and potential health risks.

In a one year period (March 1990 to March 1991) the pattern of diseases in geriatric patients (over 60 years of age) admitted to the medical wards at Kenyatta National Hospital (KNH) was studied. In all, there were 1296 patients (M:F = 1.7:1) in this age group forming 11.5% of all admissions during the study period. 1008 (77.8%) of the geriatric patients were between 60 and 79 years of age. Most of the admissions (86.4%) were first admissions. The mean number of diseases per geriatric patient was 1.4. Hypertension and Cardiomyopathy were the commonest single diseases recorded, making up 43.9% of all diseases in this patient population. The commonest neurological diagnosis was stroke, which occurred in a setting of hypertension or cardiomyopathy in all the patients in whom it was diagnosed. The mean duration (+/- 2SD) of stay in the hospital in this patient population was 43 (+/- 19) days. Eighty eight (6.8%) of the patients died, the commonest cause of death being heart failure due to cardiomyopathy or hypertensive heart disease. It is concluded that geriatric patients form a sizeable proportion of our medical admissions and that a large proportion suffer from diseases of the cardiovascular system. It is thus recommended that further studies be carried out on the pattern of diseases in such patients and optimal management strategies for their ailments be outlined.

The antihypertensive effect of the fixed combination of timolol, a beta-blocking agent, hydrochlorothiazide, a thiazide diuretic, and amiloride, a potassium sparing agent, was compared against that of methyldopa in an open study lasting 16 weeks in 32 ambulatory African patients with previously untreated diastolic blood pressure of 95-120 mm Hg. A significant fall in mean diastolic and systolic blood pressure was achieved in both groups up to 8 weeks of treatment and was sustained in the timolol-hydrochlorothiazide-amiloride group during the entire follow-up. In the methyldopa group, mean diastolic and systolic blood pressure rose during follow-up. At 16 weeks the fall in mean diastolic and systolic blood pressure was significantly greater in the timolol-hydrochlorothiazide-amiloride treated patients than in the methyldopa group. Adverse reactions were more frequent and severe in the methyldopa group than in timolol-hydrochlorothiazide-amiloride treated patients. It is concluded that the fixed drug combination of timolol-hydrochlorothiazide-amiloride (Moducren) is effective in controlling mild to moderate hypertension in Africans and is better tolerated than methyldopa in these patients. It is further noted that hypertensive patients can be treated with a combination tablet once a day. This is of crucial significance as it would promote better compliance and, hence, minimize the sequelae of poorly controlled hypertension.

Twenty nine patients with rickets were studied in a one year period. The majority of patients (17/29) were below 2 years of age. Most of them had nutritional rickets resulting from a combination of factors. Premature delivery, nonexposure to sunlight, nutritional marasmus and inappropriate dietary intake. Some had familial hypophosphataemic rickets, others had renal tubular acidosis while the rest had rickets with a familial tendency. Both the previous hospital records and the present study indicate that rickets is a persistent problem in children in the community and should be suspected in children who present with features of failure to thrive, among other conditions.

Although military conflicts are common on the African continent, there is a paucity of data regarding bomb-blast injuries in this region and in Kenya in particular. This paper describes the pattern of maxillofacial injuries sustained after the August 1998 bomb blast that occurred in Nairobi, Kenya. A retrospective cross-sectional study was carried out using hospital-based records of 290 bomb-blast survivors admitted at the Kenyatta National Referral and Teaching Hospital in Nairobi. Using a self-designed form to record information about variables such as the sex and age of the survivors and type of location of soft- and hard-tissue injuries, it was found that of the 290 bomb-blast survivors, 78% had sustained one or more maxillofacial injuries. Soft-tissue injuries (cuts, lacerations or bruises) were the most common, constituting 61.3% of all injuries in the maxillofacial region; 27.6% had severe eye injuries, while 1.4% had fractures in the cranio-facial region. This paper concludes that the effective management of bomb-blast injuries as well as those caused by other types of disaster requires a multidisciplinary approach. The high percentage of maxillofacial injuries confirm that maxillofacial surgeons should form an integral part of this multidisciplinary team.

In a 6 year period (1984-1989) we have had the opportunity to take care of five patients who had nephrotic syndrome and became pregnant. Four of them had mesangial proliferative glomerulonephritis while one had focal segmental glomerulosclerosis. Four of the pregnancies went to term while one was terminated at 34 weeks gestation because of deteriorating renal function in the mother. All the pregnancies ended in delivery of normal babies. However, two patients have since died of end stage renal disease, while the remaining three continue to be nephrotic with reduced levels of renal function following the deliveries.

Adolescent sexuality is a highly charged moral issue in Kenya and Zambia. Nurse-midwives are the core health care providers of adolescent sexual and reproductive health services but public health facilities are under-utilised by adolescents. The aim of this study was to investigate attitudes among Kenyan and Zambian nurse-midwives (n=820) toward adolescent sexual and reproductive health problems, in order to improve services for adolescents. Data were collected through a questionnaire. Findings revealed that nurse-midwives disapproved of adolescent sexual activity, including masturbation, contraceptive use and abortion, but also had a pragmatic attitude to handling these issues. Those with more education and those who had received continuing education on adolescent sexuality and reproduction showed a tendency towards more youth-friendly attitudes. We suggest that critical thinking around the cultural and moral dimensions of adolescent sexuality should be emphasised in undergraduate training and continuing education, to help nurse-midwives to deal more empathetically with the reality of adolescent sexuality. Those in nursing and other leadership positions could also play an important role in encouraging wider social discussion of these matters. This would create an environment that is more tolerant of adolescent sexuality and that recognises the beneficial public health effect for adolescents of greater access to youth-friendly sexual and reproductive health services.

Renal transplantation is not readily available in the majority of countries in Africa. It is expensive and difficult to sustain on the meagre funds allocated to health. We report our short experience with fifteen living donor recipients followed in our unit for at least 24 months, range 26 - 48 (mean 35 months) post-transplantation. The donors and recipients were mostly young adults with mean ages of 36.7 years and 32.6 years respectively. The majority of the donors and recipients were males. The donors in most cases were siblings. Within this time, one graft has been lost at one year and the patient restarted on haemodialysis. Three patients died, two within the first year, the third at 23 months after transplantation, all with functioning grafts. The one year graft and patient survival rates were 93% and 86.6% respectively. The second year graft survival rates remained at 93% and the patients survival rate 80%. The nature and frequency of complications seen in these patients is comparable to those in other centres. Of all medical complications, bacterial infections contributed 69.4% of all infections. Cardiovascular complications comprised 31.25% of the complications. Hypertension seen in 85.5% of the patients accounted for 65% of the cardiovascular complications. Acute rejections were common and occurred in seven patients. Transplantation is a viable mode of renal replacement therapy (RRT) in our environment. The practice should be supported to make it more readily available to the many young end stage renal failure (ESRF) patients.

KEMRI Centre for Geographic Medicine Research-Coast, P,O, Box 43640, Nairobi, Kenya. sekela_mwakyusa@yahoo.com BACKGROUND: The structured admission form is an apparently simple measure to improve data quality. Poor motivation, lack of supervision, lack of resources and other factors are conceivably major barriers to their successful use in a Kenyan public hospital setting. Here we have examined the feasibility and acceptability of a structured paediatric admission record (PAR) for district hospitals as a means of improving documentation of illness. METHODS: The PAR was primarily based on symptoms and signs included in the Integrated Management of Childhood Illness (IMCI) diagnostic algorithms. It was introduced with a three-hour training session, repeated subsequently for those absent, aiming for complete coverage of admitting clinical staff. Data from consecutive records before (n = 163) and from a 60% random sample of dates after intervention (n = 705) were then collected to evaluate record quality. The post-intervention period was further divided into four 2-month blocks by open, feedback meetings for hospital staff on the uptake and completeness of the PAR. RESULTS: The frequency of use of the PAR increased from 50% in the first 2 months to 84% in the final 2 months, although there was significant variation in use among clinicians. The quality of documentation also improved considerably over time. For example documentation of skin turgor in cases of diarrhoea improved from 2% pre-intervention to 83% in the final 2 months of observation. Even in the area of preventive care documentation of immunization status improved from 1% of children before intervention to 21% in the final 2 months. CONCLUSION: The PAR was well accepted by most clinicians and greatly improved documentation of features recommended by IMCI for identifying and classifying severity of common diseases. The PAR could provide a useful platform for implementing standard referral care treatment guidelines. PMID: 16857044 [PubMed] PMCID: PMC1555611

Nine students (2.2%) had significant proteinuria while 14 (3.5%) had microscopic haematuria. Two students had combined proteinuria and haematuria. There was no statistically significant difference in the prevalence of proteinuria and/or haematuria between the sexes. Other urinary abnormalities detected were leucocyturia in 14(3.5%) and nitrites in four (1%). Leucocyturia was commonner in females (p = 0.001). Cloudy urinary appearance was significantly associated with the presence of leucocyturia (p = 0.0028) and proteinuria (p = 0.0276). Neither personal history of recurrent sore throat and skin infections nor family history of hypertension, diabetes mellitus or kidney disease was significantly associated with proteinuria or haematuria. Blood pressure tended to increase with age. Mean systolic and diastolic blood pressures were significantly higher in boys than girls in the age group 15-18 years (P < 0.001). Of the 397 students whose blood pressures were measured, four (1%) were found to be hypertensive. Weight and body mass index were strong positive correlates of blood pressure. The prevalence of proteinuria, haematuria, other urinary abnormalities and hypertension ranges between 1% and 3.5% among teenage secondary school children. The majority are asymptomatic and have no significant associations. It is recommended that routine urinalysis and blood pressure measurements should be part of the school health service so as to identify asymptomatic students who require close monitoring and/or intervention.

Department of Paediatrics and Child Health, College of Health Sciences, University of Nairobi, P.O. Box 20956-00202, Nairobi, Kenya. BACKGROUND: Early growth in very low birth weight (VLBW) infants has been found predictive of their later outcomes. This has led to increased interest in establishing measures to optimise such growth. In facilities without the resources required to undertake long-term audits for all the high risk infants they graduate, these growth parameters may also be used as selection criteria for those meriting such follow up reducing costs. OBJECTIVES: To describe early growth patterns among a cohort of VLBW infants and determine some of the factors associated with poor growth among them. DESIGN: Cross section survey. SETTING: Kenyatta National Hospital, Nairobi, Kenya. SUBJECTS: One hundred and seventy five neonatal survivors. RESULTS: Of the 175 infants recruited, the male/female ratio was 4:6, sixty four (36.6%) were intrauterine growth retarded while significant illnesses during the neonatal period were reported in 109 (62.3%). Forty seven percent of the infants had been fed on exclusive breast milk, 33% on mixed feeds while 20% received exclusive preterm formula. The mean neonatal weight gain for the whole cohort was 13.5 (3.9) g/kg/day, length of 0.34 (0.11) cm/week and head circumference of 0.32 (0.71) cm/week. By term only 33 (18.9%), 37 (21.1%) and 48 (28%) had reached the expected (the 3rd percentile) weight, length and head circumference respectively. Sixty percent of the infants gained weight at <15 g/kg/day while 70% and 78% grew in head circumference and length at < 0.5 cm/week respectively. At term weight, head and linear growth faultering were recorded in 81%, 72% and 79% respectively. The factors that were associated with better growth at this stage included feeding on preterm formula (P < 0.001) and absence of neonatal morbidity (P < 0.001). Infants who were appropriate for gestational age at birth also had better catch up growth at term compared to those born small for gestation (P < 0.001) but their neonatal growth itself was not significantly better. CONCLUSION: The mean neonatal growth in all anthropometric measures was less than expected and by the time of their expected delivery, less than 30% of these infants had reached the 3rd percentile of the expected measurement in all the three growth parameters. Choice of milk and neonatal morbidity influenced these growth patterns. RECOMMENDATIONS: Routine fortification of mother's milk or addition of preterm formula and reorganised care of sick newborns is recommended to improve early growth.

Department of Paediatrics, University of Nairobi. To determine whether the "Baby Cloche" heat shield improves temperature control in low birth-weight infants we compared serial temperatures in 11 preterm infants nursed with or without the Cloche. Mean birth weights were 1490 and 1510 gm, mean weights at time of study 1680 and 1710 gm and mean postnatal age 20 and 27 days for study and control infants respectively. Serial measurements of rectal, abdominal skin, dorsum of the foot, Cloche wall and room temperature were recorded once or twice daily for 2 to 5 days. Mean rectal temperatures increased with increasing age from 35.3 in the first week of life to 37.0 degrees C by the third week (P less than 0.001). In infants nursed under the Cloche who were over 2 weeks of age mean rectal, abdominal and foot temperatures were 0.5, 0.6 and 1.6 degrees C higher (P less than 0.001); in younger infants there was no significant difference in any of the temperatures. Our findings suggest that the "Baby Cloche" improves temperature control in preterm infants over 1600 gm who are more than 2 weeks of age. PMID: 1628548 [PubMed - indexed for MEDLINE]

Steady state concentrations of three anticonvulsant drugs (phenobarbitone, phenytoin and carbamazepine) were measured in plasma samples from fifteen patients (eight males and seven females; ages: 13-49 years; body weights: 44-70 kg), attending the outpatient Neurology Clinic at Kenyatta National Hospital. In addition, total protein and albumin levels were measured in plasma from patients taking phenytoin. Total protein levels were normal (range: 6.3-7.6 g/dl) in all patients except in one patient (10.7 g/dl). Albumin levels were also normal (range: 3.7-4.1 g/dl) in all patients except one (25.4 g/dl). One patient on phenobarbitone and three patients on phenytoin had no detectable drug levels in their plasma. In the remainder, phenobarbitone, phenytoin and carbamazepine steady state concentrations were 8.7-21.1 mg/L (N = 8), 9.3-27.3 mg/L (N = 6) and 10-19.7 mg/L (N = 5), respectively. The unbound fraction of phenytoin in plasma (fu) was normal(approximately 0.1) in six patients, but relatively high (0.2) in one patient. Most patients in the study complied with the prescribed treatment and their epilepsy was controlled. Cases where drug levels were undetectable probably arose from a lack of money to purchase all prescribed medicines rather than deliberate non-compliance. Routine monitoring of anticonvulsant drug levels may improve management of epileptic patients.

As part of a study to assess zoonotic milk-borne health risks, seasonal survey data and unpasteurized milk samples were collected between January 1999 and February 2000 from randomly selected informal milk market agents (220 and 236 samples in the dry and wet seasons, respectively) and from households purchasing raw milk (213 and 219 samples in the dry and wet seasons, respectively) in rural and urban locations in Central Kenya and screened for antibiotics, Brucella abortus (B. abortus) and presence of Escherichia coli (E. coli 0157:H7).The latter was assessed based on samples from consumer households only. Antibodies to B. abortus were screened using the indirect antibody Enzyme Linked Immunosorbent Assay (ELISA) and the Milk Ring Test (MRT). The presence of E. coli 0157:H7 was assessed by culture, biochemical characterization, serological testing for production of verocytotoxin one (VTI) and two (VT2) and polymerase chain reaction (PCR) analysis for the presence of genes encoding for the toxins.                                                                                                         The prevalence of antibodies to B.abortus varied considerably ranging from none in milk sold in small units and originating from intensive production systems to over 10% in samples that were bulked or originating from extensive production systems. E. coli 0157:H7 was isolated from two samples (0.8%), one of which produced VTI. All urban consumers (100%) and nearly all rural consumers (96%) of marketed milk boiled the milk before consumption, mainly in tea, thus reducing chances of exposure to live pathogens and potential health risks.

A 30 year old female with an unexpected right adrenal phaechromacytoma invading the renal vein, the inferior vena cava and extending into the right atrium is presented. She also had BuddChiari syndrome due to invasion of the hepatic veins by the tumour. Additionally, the tumour had metastasised to the liver and the lungs. Despite elevated 24 hour urinary vanillylmandelic acid (VMA) the patient was normotensive pre-operatively. The patient underwent right adrenalectomy and extended nephrectomy with milking of the tumaur from the inferior vena cava. Unfortunately, the patient developed multiple hypotensive episodes and adult respiratory distress syndrome post-operatively and died three weeks after surgery.

Department of Cariology Endodontology Pedodontology, Academic Centre for Dentistry Amsterdam (ACTA), Louwesweg 1, 1066 EA Amsterdam, The Netherlands. The use of Chewing sticks (Miswaki) in the third world for control of dental plaque is very popular. Some of the studies that have been conducted on this subject have reported marked decrease in the incidences of dental caries and periodontal diseases in the users of Miswaki, when compared to the users of the conventional toothbrush living under similar conditions. Various mechanisms by which the Miswaki contributes to this phenomenon have been suggested. The purpose of the present study was to investigate in vitro, the anti-microbial action, the potential acid buffer capacity and fluoride content of crude aqueous extracts of eight commonly used chewing sticks from three regions in Kenya. The results obtained in the study, showed that one of the Miswaki had remarkable antibiotic activity against three stains of oral bacteria. Three of the Miswaki had significant acid buffer capacity. None of the eight Miswaki showed any significant fluoride release.

PIP: This research report studies several biochemical and histochemical aspects of cervical carcinoma and explores their use in follow-up of patients undergoing radiotherapy. Material came from 19 patients with invasive cervical carcinoma admitted to Kenyatta National Hospital. A control group consisted of 20 women matched for age who attended clinics at the hospital but were not suffering from any malignant disease; control tissue for histological examination was obtained from 3 women who had undergone hysterectomy for uterine fibroids. Biochemical assays for alkaline and acid phosphatases in patients with cervical carcinoma show an increase in alkaline phosphatase in carcinomatous tissue (35.7 umoles/hr/mg) as opposed to normal tissue (7.2). Acid phosphatase values were only moderately raised. Assays of the same enzymes in blood showed a less marked difference between patients and controls (ranges of 7.5-20.8 and 3-14, respectively). When examined histochemically, increased alkaline phosphatase activity was observed in connective tissue, epithelium of the glands and blood capillaries of tumor tissue. 1 section containing normal tissue bordering carcinomatous tissue demonstrated normal alkaline phosphatase activity in the normal tissue and increased activity in the tumor tissue. In summary, there is increased enzyme activity around the tumor areas, but values for serum levels show an overlap of normal and abnormal cases and are therefore not predictive. Results demonstrate a clear difference in activities of these enzymes in carcinomatous tissue and normal tissue, which may be of value in follow-up care.

One hundred children comprising of 57 males and 43 females aged between 8 and 24 months entered the study. 46 children had single and 54 children had multiple helminth infections. All children received albendazole 200 mg (10 ml) suspension as a single dose. Albendazole proved very effective and safe in the treatment of single and multiple helminth infections in children under 2 years of age, achieving cure rates of 100% in both Ascaris lumbricoides and Necator americanus respectively, 83% in Trichuris trichiura and 66% in Hymenolepis nana. Treatment of polyparasitism appears to be of benefit in improving nutritional status using haemoglobin concentrations as an index.

Asiatic acid (AA) is a pentacyclic triterpene found in Centella asiatica. In the present study, the mechanism of anticancer effect of AA on skin cancer was investigated. AA decreased viability and induced apoptosis in human melanoma SK-MEL-2 cells in a time- and dose-dependent manner. AA also markedly increased intracellular reactive oxygen species (ROS) level and enhanced the expression of Bax but not Bcl-2 protein in the cells. In addition, AA-induced activation of caspase-3 activity in a dose-dependent manner. Pretreatment with Trolox, an antioxidant, significantly blocked the induction of Bax and activation of caspase-3 in AA-treated cells. Furthermore, Ac-DEVD-CHO, a specific caspase-3 inhibitor, and Trolox prevented the AA-induced apoptosis. AA did not elevate p53 nuclear protein levels that are present in a mutant form in SK-MEL-2 cells. These results suggest that AA-induced apoptosis may be mediated through generation of ROS, alteration of Bax/Bcl-2 ratio and activation of caspase-3, but p53-independent. These results further suggest that AA may be a good candidate for the therapeutic intervention of human skin cancer.

The average procedure time was 7 minutes. Bleeding lasted over 1 week in 4%, total blood loss was over 50 ml in 3.1%, and immediate side effects were syncope in 1.3%, nausea and vomiting in 1.8% and pain in 5.4%. There were 2 (0.8%) cases of endometritis. In Kenya where 60% of all gynecological hospital admissions are for septic abortions, it is essential to provide safe termination as a backup for family planning method failures.

The antihypertensive effect of the fixed combination of timolol, a beta-blocking agent, hydrochlorothiazide, a thiazide diuretic, and amiloride, a potassium sparing agent, was compared against that of methyldopa in an open study lasting 16 weeks in 32 ambulatory African patients with previously untreated diastolic blood pressure of 95-120 mm Hg. A significant fall in mean diastolic and systolic blood pressure was achieved in both groups up to 8 weeks of treatment and was sustained in the timolol-hydrochlorothiazide-amiloride group during the entire follow-up. In the methyldopa group, mean diastolic and systolic blood pressure rose during follow-up. At 16 weeks the fall in mean diastolic and systolic blood pressure was significantly greater in the timolol-hydrochlorothiazide-amiloride treated patients than in the methyldopa group. Adverse reactions were more frequent and severe in the methyldopa group than in timolol-hydrochlorothiazide-amiloride treated patients. It is concluded that the fixed drug combination of timolol-hydrochlorothiazide-amiloride (Moducren) is effective in controlling mild to moderate hypertension in Africans and is better tolerated than methyldopa in these patients. It is further noted that hypertensive patients can be treated with a combination tablet once a day. This is of crucial significance as it would promote better compliance and, hence, minimize the sequelae of poorly controlled hypertension.

Autonomic nervous function was assessed in twenty two patients (16 males and 6 females) with chronic renal failure on conservative management. The presenting symptoms were postural dizziness in 10(45%), impotence in 4(18%) patients and 1 patient each with diplopia, urinary urgency and nocturnal diarrhoea. The following autonomic function tests were performed; valsalva manoeuvre, heart rate response to deep breathing, heart rate response to posture and postural change in blood pressure. Fifteen (68%) patients had abnormal autonomic function tests. Out of these patients, 14(93%) had abnormalities of the parasympathetic system and only one had abnormalities in the sympathetic system. There was a negative correlation between the creatinine levels and the following; valsalva ratio (r = -0.72 p < 0.001), heart rate response to standing (r = -0.56 p < 0.01) and heart rate response to deep breathing (r = -0.45 p < 0.05).

OBJECTIVES: To determine the frequency of adenotonsillectomy in a sample of Kenyan hospitals and to review indications, timing and complications in 97 cases of adenotonsillectomy done by the authors. DESIGN: Retrospective, descriptive study. SETTING: Kenyatta National, Nairobi, Aga Khan, Gertrude and Mater Hospitals. RESULTS: Adenotonsillectomy is the most frequent otolaryngologic surgical operation. Indications for surgery were upper airway obstruction in 61.3%, recurrent tonsillitis in 28.7% and both in 7.5%. Surgery was indicated during the acute stage in 6.8% of cases. There was one case of post-operative acute airway obstruction. Post operative bleeding from the tonsillar bed was encountered in 2.1% of cases. CONCLUSION: Adenotonsillectomy is the most common otolaryngologic surgical operation in our set-up. The low frequency of complications and a short hospital stay puts up a case for routine adenotonsillectomy as a day surgery procedure.

The presence of E. coli 0157:H7 was assessed by culture, biochemical characterization, serological testing for production of verocytotoxin one (VTI) and two (VT2) and polymerase chain reaction (PCR) analysis for the presence of genes encoding for the toxins.                                                                                                         The prevalence of antibodies to B.abortus varied considerably ranging from none in milk sold in small units and originating from intensive production systems to over 10% in samples that were bulked or originating from extensive production systems. E. coli 0157:H7 was isolated from two samples (0.8%), one of which produced VTI. All urban consumers (100%) and nearly all rural consumers (96%) of marketed milk boiled the milk before consumption, mainly in tea, thus reducing chances of exposure to live pathogens and potential health risks.

In a one year period (March 1990 to March 1991) the pattern of diseases in geriatric patients (over 60 years of age) admitted to the medical wards at Kenyatta National Hospital (KNH) was studied. In all, there were 1296 patients (M:F = 1.7:1) in this age group forming 11.5% of all admissions during the study period. 1008 (77.8%) of the geriatric patients were between 60 and 79 years of age. Most of the admissions (86.4%) were first admissions. The mean number of diseases per geriatric patient was 1.4. Hypertension and Cardiomyopathy were the commonest single diseases recorded, making up 43.9% of all diseases in this patient population. The commonest neurological diagnosis was stroke, which occurred in a setting of hypertension or cardiomyopathy in all the patients in whom it was diagnosed. The mean duration (+/- 2SD) of stay in the hospital in this patient population was 43 (+/- 19) days. Eighty eight (6.8%) of the patients died, the commonest cause of death being heart failure due to cardiomyopathy or hypertensive heart disease. It is concluded that geriatric patients form a sizeable proportion of our medical admissions and that a large proportion suffer from diseases of the cardiovascular system. It is thus recommended that further studies be carried out on the pattern of diseases in such patients and optimal management strategies for their ailments be outlined.

The antihypertensive effect of the fixed combination of timolol, a beta-blocking agent, hydrochlorothiazide, a thiazide diuretic, and amiloride, a potassium sparing agent, was compared against that of methyldopa in an open study lasting 16 weeks in 32 ambulatory African patients with previously untreated diastolic blood pressure of 95-120 mm Hg. A significant fall in mean diastolic and systolic blood pressure was achieved in both groups up to 8 weeks of treatment and was sustained in the timolol-hydrochlorothiazide-amiloride group during the entire follow-up. In the methyldopa group, mean diastolic and systolic blood pressure rose during follow-up. At 16 weeks the fall in mean diastolic and systolic blood pressure was significantly greater in the timolol-hydrochlorothiazide-amiloride treated patients than in the methyldopa group. Adverse reactions were more frequent and severe in the methyldopa group than in timolol-hydrochlorothiazide-amiloride treated patients. It is concluded that the fixed drug combination of timolol-hydrochlorothiazide-amiloride (Moducren) is effective in controlling mild to moderate hypertension in Africans and is better tolerated than methyldopa in these patients. It is further noted that hypertensive patients can be treated with a combination tablet once a day. This is of crucial significance as it would promote better compliance and, hence, minimize the sequelae of poorly controlled hypertension.

Oral infection with Herpes Simplex Virus (HSV) is a frequent and well documented complication in immunosuppressed individuals including patients on immunosuppressive medication. We report the development of severe oral infection with HSV type 1 in a 34 year old woman with type 1 diabetes mellitus and end stage renal disease (ESRD) following cadaveric renal transplantation at the Western General Hospital, Edinburgh. The role of acyclovir in therapy and chemoprophylaxis is discussed.

A model based on reaction kinetics and elemental diffusion is pro­posed to account for the presence of double inflection in the hardness profiles of the heat-affected zone (HAZ) in weld­ments of AI-Li-X alloys tested without postweld heat treatment (PWHT). Such profiles are particularly evident when 1) the base metal is in the peak-aged (T8 or T6) temper condition prior to welding; 2) the welding process is a high-heat input process, i.e., gas tungsten arc (GTA), gas metal arc (GMA) or plasma arc (PA) welding; and 3) a filler alloy deficient in lithium (i.e., AA 2319) is used. In the first part of this paper, the theoretical mechanisms are presented. It is proposed that the double inflection appears due to complete or partial reversion of the semi-coherent, plate-like precipitates (i.e., ө', T1 or S'); coarsening of the platelike precipitates at constant volume fraction; precipitation of d' as a result of natural aging; and diffusion of lithium from the HAZ into the weld pool due to the concentration gradient between the weld pool and the base metal. In the second part (to be published in next month's Welding Journal), experimental validation of the model is provided using weld-ments of the AI-Li-Cu Alloy 2095.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Danish Bilharziasis Laboratory, Charlottenlund. The association between Schistosoma mansoni infection and kidney lesions was investigated in school children selected from three primary schools in Machakos District, Kenya, namely Miu (n = 159), Kitengei (n = 160) and Misuuni (n = 99) schools. The children were examined parasitologically for S. mansoni infection, clinically for enlargement of the liver and spleen, and biochemically for proteinuria and serum and urine creatinine. High prevalences of S. mansoni infection, ranging from 84-96%, were seen in all the schools, but the geometric mean intensity of egg excretion varied, being relatively low in Misuuni (31 eggs/g), medium in Miu (182 eggs/g) and high in Kitengei (413 eggs/g). The prevalence of pathological proteinuria (> or = 200 mg/l) in the schools ranged from 10.1% in Miu to 28.8% in Kitengei. No difference in the levels of proteinuria was noted between age or sex groups. No association between intensity of infection and pathological proteinuria was observed in any of the schools, nor was any correlation between organomegaly and proteinuria observed. However, significant correlations between malaria and organomegaly (p < 0.001) and between malaria and proteinuria (p < 0.05) were observed when pooling data from all schools. These findings suggest that S. mansoni induced nephrotic syndromes are not common in children from this highly endemic area of Kenya.

Acute renal failure (ARF) complicated the use of traditional herbal remedies in six adult patients seen at Kenyatta National Hospital in a 2-year period (August 1984 to August 1986). This comprised 10.9% of all the cases of ARF and 24% of the cases of ARF due to medical causes. All the patients were oliguric and the period of oliguria in the four patients who survived ranged between 19-57 days (mean 26.3 days). Five of the patients had evidence of fluid overload. The blood urea nitrogen and serum creatinine were elevated in all the patients. The serum sodium was normal in all, while the serum potassium was elevated in 2 cases. Identity of the herbal medication was unknown in all the cases. The indication was abdominal pain in 4 cases, infertility and abdominal pain in one and prophylaxis against witchcraft in the other. All the patients were started on haemodialysis, two of them having had periods of peritoneal dialysis for 12 and 16 days. Two patients died. Of the four surviving patients, follow up has been carried out for 8, 6, 5 and 4 months. At four months follow up the creatinine clearance in the 4 surviving patients have been 54, 63, 51 and 43 ml/min.

Fracture mechanics principles have been used to study the effects of welding on the rate of fatigue crack growth (FCG) in a low-carbon structural steel. The steel concerned is used widely in the fabrication of the structural frame-work of passenger buses. Tests were carried out on the base metal (BM), heat affected zone (HAZ) and weld metal (WM). Both the near threshold and midrange regimes of crack growth were studied. In the midrange regime, the FCG rate was highest in the HAZ and lowest in the WM. Near the threshold, the FCG rate was highest in the BM and lowest in the WM. The results are explained in terms of microstructural changes due to welding, welding residual stresses, and fracture mechanisms. Recommendations to reduce the incidence of fatigue cracking have been made.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Although military conflicts are common on the African continent, there is a paucity of data regarding bomb-blast injuries in this region and in Kenya in particular. This paper describes the pattern of maxillofacial injuries sustained after the August 1998 bomb blast that occurred in Nairobi, Kenya. A retrospective cross-sectional study was carried out using hospital-based records of 290 bomb-blast survivors admitted at the Kenyatta National Referral and Teaching Hospital in Nairobi. Using a self-designed form to record information about variables such as the sex and age of the survivors and type of location of soft- and hard-tissue injuries, it was found that of the 290 bomb-blast survivors, 78% had sustained one or more maxillofacial injuries. Soft-tissue injuries (cuts, lacerations or bruises) were the most common, constituting 61.3% of all injuries in the maxillofacial region; 27.6% had severe eye injuries, while 1.4% had fractures in the cranio-facial region. This paper concludes that the effective management of bomb-blast injuries as well as those caused by other types of disaster requires a multidisciplinary approach. The high percentage of maxillofacial injuries confirm that maxillofacial surgeons should form an integral part of this multidisciplinary team.

Adolescent sexuality is a highly charged moral issue in Kenya and Zambia. Nurse-midwives are the core health care providers of adolescent sexual and reproductive health services but public health facilities are under-utilised by adolescents. The aim of this study was to investigate attitudes among Kenyan and Zambian nurse-midwives (n=820) toward adolescent sexual and reproductive health problems, in order to improve services for adolescents. Data were collected through a questionnaire. Findings revealed that nurse-midwives disapproved of adolescent sexual activity, including masturbation, contraceptive use and abortion, but also had a pragmatic attitude to handling these issues. Those with more education and those who had received continuing education on adolescent sexuality and reproduction showed a tendency towards more youth-friendly attitudes. We suggest that critical thinking around the cultural and moral dimensions of adolescent sexuality should be emphasised in undergraduate training and continuing education, to help nurse-midwives to deal more empathetically with the reality of adolescent sexuality. Those in nursing and other leadership positions could also play an important role in encouraging wider social discussion of these matters. This would create an environment that is more tolerant of adolescent sexuality and that recognises the beneficial public health effect for adolescents of greater access to youth-friendly sexual and reproductive health services.

Ten patients with acute and 60 with chronic renal failure (both groups having hyperkalaemia), were managed at Kenyatta National Hospital in the medical wards and Renal Unit between August, 1995 and January, 1996. They were divided into seven different treatment groups, each consisting of ten patients. Treatment A glucose 25g i.v. with insulin 10 units i.v., treatment B 50 mmol of 8.4% sodium bicarbonate infusion, treatment C 0.5mg of salbutamol i.v. in 50mls 5% dextrose, treatment D was a combination of treatments A and B, treatment E was a combination of treatment B and C, treatment F was a combination of treatments A and C while treatment G was a combination of treatments A and B and C. Serum potassium was measured, 30 minutes, 1 hour, 2 hours, 4 hours and 8 hours after treatment. Plasma glucose concentration was measured before treatment was given and 1 hour after in all patients. Electrocardiography was done before treatment on all patients and repeated 30 minutes and 1 hour after treatment for the patients with hyperkalaemic changes on the initial recording. All treatment modalities had satisfactory potassium lowering effects. Of the single therapeutic approaches, treatment A and C were equieffective, but better than treatment B (P < 0.001). Amongst the two regimen combinations, treatment D and F were more efficacious than treatment E and all the single therapeutic approaches (P < 0.001). Treatment G was the most efficacious in lowering serum potassium in this study. All treatment modalities had maximum serum potassium lowering effect at 1-2 hours. A fall in plasma glucose concentration was a notable feature of treatments A and D, but significant hypoglycaemia occurred in 20% of patients receiving treatment A and in none on treatment D. The ECG changes of hyperkalaemia did not correlate with serum potassium levels. The normalisation of hyperkalaemic ECG alteration occurred within the first 30 minutes after treatment. In conclusion, combination therapies for hyperkalaemia appear to be more efficacious than single therapeutic approaches. Inclusion of salbutamol seems to protect against insulin induced hypoglycaemia. The maximum potassium lowering effect is observed 1-2 hours of administration of either agents. The potassium reducing effect remains significant compared to baseline values even after 8 hours. If dialysis cannot be instituted early enough it seems reasonable to repeat treatment every 4-6 hours to sustain the effect. Repeated administration of glucose with insulin may not be safe because of the hypoglycaemic effect. Other single and combination therapies can theoretically be repeated regularly until dialysis is initiated although this requires further clinical evaluation.

This study determined the prey base for four main carnivores found in Samburu Community group ranches and grazing area, Lion (Panthera leo), Leopard (Panthera pardus), Wild dog (Lycaon pictus) and Hyaena (Crocuta crocuta, and Hyaena hyaena). A total of 96 scat samples including, 8 from Lion, 16 Leopards', 2 Wild dogs', and 70 Hyaenas' were collected, identified and microscopically analyzed for prey hair characterisation. At least 50 different hairs from every scat sample were mounted on slides and microscopically characterized using details from reference hairs. Hairs from 18 depredated species both domestic and wild ungulates were recovered from the scat samples. Predated species were identified, as either domestic (Cow, Sheep, Goat, Donkey, and Camel) or wild ungulate prey (Grant's gazelle, plain zebra, Grevy's Zebra, Impala, Waterbuck, Dikdik, Eland, lesser Kudu, greater Kudu, Baboon, rock Hyraxes, Elephant and Oryx). The carnivores showed a relatively high kill of wild ungulate prey compared to domestic prey. Camel was the most preferred cow and donkey respectively. Grevy's zebra contributed highest to the lion's diet while the Plain zebra was most preferred by the leopard. Both the hyaena and Wild dog had a preference for the waterbuck. The Hyaena had the highest domestic depredation, while all the other big cats depredated more on wild ungulates.

Key words: Scat, group ranch, domestic, wild ungulate, prey, depredation.

Department of Cariology Endodontology Pedodontology, Academic Centre for Dentistry Amsterdam (ACTA), Louwesweg 1, 1066 EA Amsterdam, The Netherlands. The use of Chewing sticks (Miswaki) in the third world for control of dental plaque is very popular. Some of the studies that have been conducted on this subject have reported marked decrease in the incidences of dental caries and periodontal diseases in the users of Miswaki, when compared to the users of the conventional toothbrush living under similar conditions. Various mechanisms by which the Miswaki contributes to this phenomenon have been suggested. The purpose of the present study was to investigate in vitro, the anti-microbial action, the potential acid buffer capacity and fluoride content of crude aqueous extracts of eight commonly used chewing sticks from three regions in Kenya. The results obtained in the study, showed that one of the Miswaki had remarkable antibiotic activity against three stains of oral bacteria. Three of the Miswaki had significant acid buffer capacity. None of the eight Miswaki showed any significant fluoride release.

East African Medical Journal. 1997;74(8):556-568.". In: East African Medical Journal. 1997;74(8):556-568. University of Nairobi.; 1997. Abstract

Four hundred and three teenage secondary school students (50.6% males) from two girls' and two boys' Nairobi City Schools, selected by stratified sampling, were screened to determine the prevalence of proteinuria, haematuria, nitrituria and hypertension. Nine students (2.2%) had significant proteinuria while 14 (3.5%) had microscopic haematuria. Two students had combined proteinuria and haematuria. There was no statistically significant difference in the prevalence of proteinuria and/or haematuria between the sexes. Other urinary abnormalities detected were leucocyturia in 14(3.5%) and nitrites in four (1%). Leucocyturia was commonner in females (p = 0.001). Cloudy urinary appearance was significantly associated with the presence of leucocyturia (p = 0.0028) and proteinuria (p = 0.0276). Neither personal history of recurrent sore throat and skin infections nor family history of hypertension, diabetes mellitus or kidney disease was significantly associated with proteinuria or haematuria. Blood pressure tended to increase with age. Mean systolic and diastolic blood pressures were significantly higher in boys than girls in the age group 15-18 years (P < 0.001). Of the 397 students whose blood pressures were measured, four (1%) were found to be hypertensive. Weight and body mass index were strong positive correlates of blood pressure. The prevalence of proteinuria, haematuria, other urinary abnormalities and hypertension ranges between 1% and 3.5% among teenage secondary school children. The majority are asymptomatic and have no significant associations. It is recommended that routine urinalysis and blood pressure measurements should be part of the school health service so as to identify asymptomatic students who require close monitoring and/or intervention.

Department of Paediatrics and Child Health, College of Health Sciences, University of Nairobi, P.O. Box 20956-00202, Nairobi, Kenya. BACKGROUND: Early growth in very low birth weight (VLBW) infants has been found predictive of their later outcomes. This has led to increased interest in establishing measures to optimise such growth. In facilities without the resources required to undertake long-term audits for all the high risk infants they graduate, these growth parameters may also be used as selection criteria for those meriting such follow up reducing costs. OBJECTIVES: To describe early growth patterns among a cohort of VLBW infants and determine some of the factors associated with poor growth among them. DESIGN: Cross section survey. SETTING: Kenyatta National Hospital, Nairobi, Kenya. SUBJECTS: One hundred and seventy five neonatal survivors. RESULTS: Of the 175 infants recruited, the male/female ratio was 4:6, sixty four (36.6%) were intrauterine growth retarded while significant illnesses during the neonatal period were reported in 109 (62.3%). Forty seven percent of the infants had been fed on exclusive breast milk, 33% on mixed feeds while 20% received exclusive preterm formula. The mean neonatal weight gain for the whole cohort was 13.5 (3.9) g/kg/day, length of 0.34 (0.11) cm/week and head circumference of 0.32 (0.71) cm/week. By term only 33 (18.9%), 37 (21.1%) and 48 (28%) had reached the expected (the 3rd percentile) weight, length and head circumference respectively. Sixty percent of the infants gained weight at <15 g/kg/day while 70% and 78% grew in head circumference and length at < 0.5 cm/week respectively. At term weight, head and linear growth faultering were recorded in 81%, 72% and 79% respectively. The factors that were associated with better growth at this stage included feeding on preterm formula (P < 0.001) and absence of neonatal morbidity (P < 0.001). Infants who were appropriate for gestational age at birth also had better catch up growth at term compared to those born small for gestation (P < 0.001) but their neonatal growth itself was not significantly better. CONCLUSION: The mean neonatal growth in all anthropometric measures was less than expected and by the time of their expected delivery, less than 30% of these infants had reached the 3rd percentile of the expected measurement in all the three growth parameters. Choice of milk and neonatal morbidity influenced these growth patterns. RECOMMENDATIONS: Routine fortification of mother's milk or addition of preterm formula and reorganised care of sick newborns is recommended to improve early growth.

As part of a study to assess zoonotic milk-borne health risks, seasonal survey data and unpasteurized milk samples were collected between January 1999 and February 2000 from randomly selected informal milk market agents (220 and 236 samples in the dry and wet seasons, respectively) and from households purchasing raw milk (213 and 219 samples in the dry and wet seasons, respectively) in rural and urban locations in Central Kenya and screened for antibiotics, Brucella abortus (B. abortus) and presence of Escherichia coli (E. coli 0157:H7).The latter was assessed based on samples from consumer households only. Antibodies to B. abortus were screened using the indirect antibody Enzyme Linked Immunosorbent Assay (ELISA) and the Milk Ring Test (MRT). The presence of E. coli 0157:H7 was assessed by culture, biochemical characterization, serological testing for production of verocytotoxin one (VTI) and two (VT2) and polymerase chain reaction (PCR) analysis for the presence of genes encoding for the toxins.                                                                                                         The prevalence of antibodies to B.abortus varied considerably ranging from none in milk sold in small units and originating from intensive production systems to over 10% in samples that were bulked or originating from extensive production systems. E. coli 0157:H7 was isolated from two samples (0.8%), one of which produced VTI. All urban consumers (100%) and nearly all rural consumers (96%) of marketed milk boiled the milk before consumption, mainly in tea, thus reducing chances of exposure to live pathogens and potential health risks.

Weights and heights of 674 consecutive non-insulin dependent diabetics and 358 control urban healthy Kenyans were recorded prospectively. Weights and heights of a further 162 healthy rural adults were compared retrospectively. The body mass index (weight/height2) of the non-insulin dependent diabetic was lower than that of the corresponding urban control subject. The body mass index of the rural folk was consistently lower than that of the urban dweller. This study concluded that obesity may not be a significant factor in non-insulin dependent diabetes in the African black.

A 30 year old female with an unexpected right adrenal phaechromacytoma invading the renal vein, the inferior vena cava and extending into the right atrium is presented. She also had BuddChiari syndrome due to invasion of the hepatic veins by the tumour. Additionally, the tumour had metastasised to the liver and the lungs. Despite elevated 24 hour urinary vanillylmandelic acid (VMA) the patient was normotensive pre-operatively. The patient underwent right adrenalectomy and extended nephrectomy with milking of the tumaur from the inferior vena cava. Unfortunately, the patient developed multiple hypotensive episodes and adult respiratory distress syndrome post-operatively and died three weeks after surgery.

This study explored the extent to which cognitive competence in 5-yr old Kenyan children was associated with earlier nutritional factors, family conditions and toddler characteristics. Food intake during the 18th-30th mths and physical stature at 30 mths were associated with cognitive skills at 5 yrs. Measures of family background, abilities of the child as a toddler and current schooling were also associated with cognitive abilities at 5 yrs. These variables influenced development independently, so that later cognitive competence was best predicted by a combination of earlier nutritional, family and toddler characteristics.

PIP: The efficacy and complication rate of menstrual regulation with the hand-held Karman cannula was tested on 223 women with amenorrhea up to 56 days in the Dept. of Obstetrics and Gynecology, University of Nairobi, Kenya from October 1982-January 1983. 195 women had positive pregnancy tests, while menstrual regulation was done on the others because of concern over late menses. the procedures were done without anesthesia with a 50 ml vacuum syringe fitted with a self-locking plunger, a rubber adaptor and stop cock, 5-8 mm flexible plastic Karman cannula and a toothless volsellum, using hibitane solution and savlon antiseptic. The average procedure time was 7 minutes. Bleeding lasted over 1 week in 4%, total blood loss was over 50 ml in 3.1%, and immediate side effects were syncope in 1.3%, nausea and vomiting in 1.8% and pain in 5.4%. There were 2 (0.8%) cases of endometritis. In Kenya where 60% of all gynecological hospital admissions are for septic abortions, it is essential to provide safe termination as a backup for family planning method failures.

Fresh blood lymphocytes from nine health donors have been compared with samples from the same donors, recovered after period of 2 to 21 months storage in liquid nitrogen, for the capacity to respond to a range of mitogens in vitro. A microculture assay was used, requireing aliquots of only 25,000 cells. The mean levels of 14C-thymidine uptake for fresh and frozen samples were closely comparable when the cells had been stimulated by PHA, Pokeweed or mitomycin-C-treated allogeneic lymphoblastoid cells. Lymphocytes from six East African donors, frozen by a very simple technique, were recovered after 3 or more years storage in liquid nitrogen. Five of the samples were in good condition as judged by cell viability and the capacity to form spontaneous 'E' rosettes with sheep erythrocytes. These five samples also responded extremely well to PHA, PWM and mitomycin-C-treated allogeneic lymphoblastoid cells using the microculture assay. This study extends the range of applications of cell banks in which small aliquots of blood lymphocytes are stored in liquid nitrogen for periods of several years.

OBJECTIVES: To determine the frequency of adenotonsillectomy in a sample of Kenyan hospitals and to review indications, timing and complications in 97 cases of adenotonsillectomy done by the authors. DESIGN: Retrospective, descriptive study. SETTING: Kenyatta National, Nairobi, Aga Khan, Gertrude and Mater Hospitals. RESULTS: Adenotonsillectomy is the most frequent otolaryngologic surgical operation. Indications for surgery were upper airway obstruction in 61.3%, recurrent tonsillitis in 28.7% and both in 7.5%. Surgery was indicated during the acute stage in 6.8% of cases. There was one case of post-operative acute airway obstruction. Post operative bleeding from the tonsillar bed was encountered in 2.1% of cases. CONCLUSION: Adenotonsillectomy is the most common otolaryngologic surgical operation in our set-up. The low frequency of complications and a short hospital stay puts up a case for routine adenotonsillectomy as a day surgery procedure.

The antihypertensive effect of the fixed combination of timolol, a beta-blocking agent, hydrochlorothiazide, a thiazide diuretic, and amiloride, a potassium sparing agent, was compared against that of methyldopa in an open study lasting 16 weeks in 32 ambulatory African patients with previously untreated diastolic blood pressure of 95-120 mm Hg. A significant fall in mean diastolic and systolic blood pressure was achieved in both groups up to 8 weeks of treatment and was sustained in the timolol-hydrochlorothiazide-amiloride group during the entire follow-up. In the methyldopa group, mean diastolic and systolic blood pressure rose during follow-up. At 16 weeks the fall in mean diastolic and systolic blood pressure was significantly greater in the timolol-hydrochlorothiazide-amiloride treated patients than in the methyldopa group. Adverse reactions were more frequent and severe in the methyldopa group than in timolol-hydrochlorothiazide-amiloride treated patients. It is concluded that the fixed drug combination of timolol-hydrochlorothiazide-amiloride (Moducren) is effective in controlling mild to moderate hypertension in Africans and is better tolerated than methyldopa in these patients. It is further noted that hypertensive patients can be treated with a combination tablet once a day. This is of crucial significance as it would promote better compliance and, hence, minimize the sequelae of poorly controlled hypertension.

In a six month period at the Kenyatta National Hospital, 46 patients (30 males) with chronic renal failure (CRF) and 22 healthy subjects have had a clinical and echocardiographic study of their cardiovascular systems. The patients with CRF were further classified as stable or in end stage renal disease (ESRD), the latter group requiring dialysis. Hypertension and circulatory congestion were the commonest clinical cardiovascular findings in patients with CRF. The patients with ESRD had significantly higher blood urea nitrogen and serum creatinine than the ones with stable CRF. Echocardiographically right ventricular size, left atrial size, aortic root diameter, left ventricular internal diameters, left ventricular end diastolic and systolic volumes, stroke volume, cardiac output, left ventricular posterior wall and interventricular septal thickness, ejection time and mitral and aortic peak flow rates were significantly higher in patients with CRF than in controls. In contrast, the circumferential fibre shortening and the ejection fraction were reduced in patients with CRF. Global left ventricular dysfunction was found in 47.8% of the patients. Using doppler flow studies, valvular incompetence was detected in a number of patients, mitral regurgitation being found in 84%.76% of the patients with CRF had varying degrees of pericardial effusion. The echocardiographic abnormalities and the pericardial effusions responded six weeks of haemodialysis in a variable manner.

A 3D FEM computer program was developed to establish the stress distributions and SCFs in thick walled cylinders with radiused entry flush and non-protruding cross bores under internal pressure. The displacement formulation and eight noded brick isoparametric elements were used. The Frontal solution technique was used due to the limited computing facilities. The variation of SCF with entry radius to main bore radius ratio was established for varying cylinder outer radius to main bore radius ratio and cross bore to main bore radius ratio. For low values of cylinder outer radius to main bore radius ratio (≤2.25), the lower values of cross bore to main bore radius ratio resulted in lower SCFs. For high values of cylinder outer radius to main bore radius ratio (>2.25),  the lower values of cross bore to main bore radius ratio resulted in higher SCFs. The cylinder with cylinder outer radius to main bore radius ratio of 2.25 was found to be a transition geometry. For very small values of cross bore to main bore radius ratio, the SCFs converged to a value of 2.2 for entry radius to main bore radius ratio of 0.2. The cylinder outer radius to main bore radius ratio of 1.75 to 3 cylinders had a constant SCF value of 2.3 at cross bore to main bore radius ratio of 0.05 and entry radius to main bore radius ratio of 0.2. A new categorization of cylinders earlier proposed in the study of plain cross-bored cylinders is further validated.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Department of Paediatrics, University of Nairobi, Kenya. Sodium and potassium levels were measured weekly in mothers' milk and in serum and urine of 41 supplemented and 25 unsupplemented very-low-birth-weight infants whose mean birth weights were 1390g and 1332g, respectively (mean gestational age, 31 weeks). Sodium intake was 5.95mmol/kg/day for the supplemented group and 2.75mmol/kg/day for controls. None of the infants in either group was hyponatremic during the 6-week period of study. Urinary sodium in the supplemented group was 15.7mmol/L as compared with 7.5mmol/L in controls. Human milk sodium was significantly lower than reported elsewhere. Growth in the supplemented group was greater than in the unsupplemented group. Since no episode of hyponatremia occurred, it was concluded that routine sodium supplementation was unnecessary.

Characteristics of 14 patients above 12 years of age with congenital polycystic liver disease attending liver clinic at KNH were analysed. The diagnosis was mainly based on ultrasonographic findings. The disease was found predominantly among the Kikuyu ethnic group with a female/male ratio of 6:1 and the peak age at presentation was in the 5th decade. The liver function tests were essentially normal in all cases with no complication directly relating to liver disease. Hypertension was found in 78.6% of cases and chronic renal failure in 35.7% of cases. There was an associated polycystic disease in at least one other abdominal organ in all cases.

The antihypertensive effect of the fixed combination of timolol, a beta-blocking agent, hydrochlorothiazide, a thiazide diuretic, and amiloride, a potassium sparing agent, was compared against that of methyldopa in an open study lasting 16 weeks in 32 ambulatory African patients with previously untreated diastolic blood pressure of 95-120 mm Hg. A significant fall in mean diastolic and systolic blood pressure was achieved in both groups up to 8 weeks of treatment and was sustained in the timolol-hydrochlorothiazide-amiloride group during the entire follow-up. In the methyldopa group, mean diastolic and systolic blood pressure rose during follow-up. At 16 weeks the fall in mean diastolic and systolic blood pressure was significantly greater in the timolol-hydrochlorothiazide-amiloride treated patients than in the methyldopa group. Adverse reactions were more frequent and severe in the methyldopa group than in timolol-hydrochlorothiazide-amiloride treated patients. It is concluded that the fixed drug combination of timolol-hydrochlorothiazide-amiloride (Moducren) is effective in controlling mild to moderate hypertension in Africans and is better tolerated than methyldopa in these patients. It is further noted that hypertensive patients can be treated with a combination tablet once a day. This is of crucial significance as it would promote better compliance and, hence, minimize the sequelae of poorly controlled hypertension.

Oral infection with Herpes Simplex Virus (HSV) is a frequent and well documented complication in immunosuppressed individuals including patients on immunosuppressive medication. We report the development of severe oral infection with HSV type 1 in a 34 year old woman with type 1 diabetes mellitus and end stage renal disease (ESRD) following cadaveric renal transplantation at the Western General Hospital, Edinburgh. The role of acyclovir in therapy and chemoprophylaxis is discussed.

Fracture mechanics principles have been used to study the effects of welding on the rate of fatigue crack growth (FCG) in a low-carbon structural steel. The steel concerned is used widely in the fabrication of the structural frame-work of passenger buses. Tests were carried out on the base metal (BM), heat affected zone (HAZ) and weld metal (WM). Both the near threshold and midrange regimes of crack growth were studied. In the midrange regime, the FCG rate was highest in the HAZ and lowest in the WM. Near the threshold, the FCG rate was highest in the BM and lowest in the WM. The results are explained in terms of microstructural changes due to welding, welding residual stresses, and fracture mechanisms. Recommendations to reduce the incidence of fatigue cracking have been made.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
