. DRONYANGODANIELW. "Onyango, D. W., Wango, E. O., Otiang.". In: MSc. Thesis, University of Nairobi. Kisipan, M.L.; 2000. Abstract

Isolated mouse interstitial cells were incubated with different concentrations of khat (Catha edulis) extract (0.06 mg/ml, 0.6 mg/ml. 6 mg/ml. 30 mg/ml and 60 mg/ml) and cell viability as well as testosterone concentration measured at 30 min intervals over a 3 h incubation period. High concentrations of khat extract (30 mg/ml and 60 mg/ml) significantly inhibited testosterone production while low concentrations (0.06 mg/ml. 0.6 mg/ml and 6 mg/ml) significantly stimulated (P < 0.05) testosterone production by mouse interstitial cells. Similarly, at concentrations of 30 mg/ml and 60 mg/ml, there was a significant decrease in interstitial cell viability, whereas at 0.06 mg/ml, 0.6 mg/ml and 6 mg/ml there was no significant decrease. There was only a weak correlation (r= 0.39) between testosterone production and viable interstitial cells. We postulate that khat extract at high concentrations may cause reproductive function impairment in the user but at low concentrations. may enhance testosterone production with accompanying effects on reproductive functions in male mice. @2006 Publishedby Elsevier Ireland Ltd.

The problem of school non-attendance is an increasing one in our setting and yet its cause has not been established. This paper presents data of work done through interviews with parents and observations of the home environments of the sample cases in attempt to establish factors associated with school non-attendance. After the initial interviews, the children were seen periodically for follow-ups, usually at two to three monthly intervals for at least one year, by the team which consisted of a consultant psychiatrist, a clinical psychologist, a paediatric registrar and a psychiatric social worker. Out of the ten cases sampled for the study, nine were of school phobia and one of conduct disorder (truancy). Generally, family characteristics significantly associated with school non-attendance in this study were neuroticism in parents, unstable family relationships occasioned by marital discord, parental expectations of high academic performance by the child and, to some extent, poverty. The common management approaches used were family therapy, counselling and anti-depressant pharmacotherapy.

This integrative review on the teaching of reading in Kenyan primary schools provides a foundation for the growing movement there to improve reading education. In gathering sources for this review, we took an inclusive historical stance. Thus, we did not dismiss research reports that lacked traditional indicators of quality such as being published in peer-reviewed journals. We used multiple methods to find relevant research and associated documents, including two trips to Kenya. The review is organized by six topics: (a) language of instruction, (b) reading instruction, (c) reading materials, (d) reading culture, (e) assessment, and (f) teacher development. The review concludes with six proposals for policymakers, educational researchers, and teacher educators for the development of reading instruction based on what we learned in reviewing the literature. The first proposals are intended specifically to address the teaching of reading in Kenya, but they may be relevant to other sub-Saharan nations. The final proposal encourages others to conduct similar reviews to make possible a handbook of reading in Africa.

BACKGROUND: In normal pregnancy, the pregnant mother paradoxically tolerates the semi-allogeneic foetus until term. Experimental and clinical data to explain such tolerance in man reflects the involvement of multiple mechanisms. OBJECTIVE: To review the data pertaining to the experimental and clinical efforts to explain why the mother immunologically tolerates a semi-allogeneic pregnancy to term. DESIGN, SETTING AND METHODS: A review of the literature on state of the art thinking among researchers and clinicians on recurrent spontaneous abortions is summarised. RESULTS: A large body of recently published data strongly suggest that a breakdown in immunological maternal-foetal interactions may lead to occasional or recurrent foetal loss. Immunoregulatory activities involving blocking antibodies, regulatory factors, immunological cells, hormones, structural proteins and cytokines constitute the pregnancy-sustaining network. CONCLUSION: The majority of the evidence reviewed points to the involvement of immunological factors in successful pregnancies. However, the underlying mechanisms are inadequately explained, are largely speculative and require more focused investigation. A complete understanding of the mechanisms involved would enhance our capacity to develop rational ways of addressing recurrent pregnancy losses.

IMPACT OF ENDOMETRIOSIS ON QUALITY OF LIFE:A PILOT STUDY.". In: Gynecol. Endocrinol. 2009 Nov; 25(11):722-5:.; 2009. Abstract

Endometriosis affects 6-10% of women in reproductive age, 35-50% of whom experience pain, infertility or both. Mild cases are managed medically but surgery provides relief to women in pain. However, symptoms recur in 75% of cases within 2 years. We investigated the impact of endometriosis on quality of life among 65 women aged 18-60 years working at a city supermaket in Giessen, Germany. Of the 65 women, 12 had undergone surgeries, 22 had dysmenorrhoea, 24 dyspareunia and 3 were infertile. Of the 22 women with dysmenorrhoea, 10 had difficulties perfoming gardening, housework, sports and leisure activities. Five of these 10 women experienced social isolation, 6 professional setbacks; 6 declined efficiency at work and 3 had taken time off work. Of the 24 women with dyspareunia, 7 experienced minimal , 12 light and 5 moderate to strong pain. only 16 of these 24 women discussed the problem with their partnes. This study demonstrates that pain is a major cause of physical, psycho-social, emotional and professional or work related impairment among women with endometriosis. Because endometriosis is  likely to impose emotional and financial burdens, we suggest that future studies should be extended to include interviews with family members.

Immunoglobulins were eluted from ovine placentae and characterized by immunoprecipitation, electrophoresis, western blotting and ELISA.IgG was shown to comprise the bulk of placental-bound immunoglobulins while smaller amounts of IgM and only trace amounts of IgA were demonstrated.Results suggest that ovine placental IgG eluted by surgical cannulation of the uterine blood vessels in situ is similar to that eluted from postpartum placentae in vitro, implying that there may be some transfer of antibodies across the maternal side of the placental barrier to the trophoblast.These antibodies are rich in IgG1 and IgG2, have a relative molecular weight of 158 kDa, and bind to an 80 kDa peptide prepared from pre-acidified ovine placental cotyledons.We propose that the binding of placental IgG to the 80 kDa antigen may prevent immunological rejection of the foetus by competitively excluding cytotoxic cells of maternal origin such as NK cells.Also, given that a similar antigen (80 kDa) has been reported in humans and equines, and shown to be saturated with IgG in term placentae, we propose that this antigen may be conserved in several mammalian species for reproductive purpose.Consequently, we suggest that the ovine placental IgG and the 80 kDa antigen may be suitable as models for the study of maternal-foetal interactions in mammalian pregnancies.

Post implantation pregnancy losses are psychologically and economically stressful to the childbearing population. The etiology in the vast majority of cases is unknown but is partly thought to result from a break-down of the maternal tolerance to the fetoplacental unit. Immunologically based therapy remains controversial but no alternative therapy is available at the moment. This article reviews the conceived immunological basis of recurrent pregnancy losses, discussing the controversies arising, and recommending the use of intravenous immunoglobulin, IVIg, in well controlled experiments for further clinical trials.

Ovine placental eluate immunoglobulins recognise isologous and third party acid-treated trophoblast microvesicle antigens in vitro.". In: J S Afr Vet Assoc. 2006 Mar;77(1):24-7.; 2006. Abstract

Placental microvesicles were prepared from ovine placentae and immunoglobulins eluted with 0.5 M glycine buffer pH 2.5. The ability of eluate immunoglobulins to re-associate with isologous (self) and third party acidified microvesicles was tested by ELISA. Ovine placental immunoglobulins re-associated with isologous and third party acidified microvesicles suggesting that at least 2 types of antigenic epitopes I and II maybe expressed on the ovine placentae. Type I antigens may be present on placentae of all ovines while type II epitopes may be paternally derived, hence unique to each pregnancy. Analysis by SDS PAGE revealed the heavy and light chains of IgG at 57 and 27 kDa, respectively, together giving a relative molecular weight of 158 kDa. Results suggest that immunoglobulins produced to placental microvesicle antigens may be directed to some but not all antigenic epitopes expressed on the trophoblast, possibly defining a mechanism by which the foetus evades maternal immunological rejection.

OBJECTIVE: To establish the magnitude of psychiatric disorders among leprosy patients in western Kenya. DESIGN: A cross-sectional descriptive study. SETTING: Busia and Teso districts in western Kenya. SUBJECTS: A sample of 152 male and female, adult leprosy patients. RESULTS: The prevalence of psychiatric morbidity (PM) was 53.29%. The PM was positively correlated with physical disability and marital status but not with age, sex, education, type of leprosy, or duration of the illness. The prevalence of psychiatric morbidity was lower among Kenyan leprosy patients compared to studies carried out in India (56% to 78%). It was high compared to the rate of psychiatric morbidity in those seeking medical help in primary health care centres in Kenya, which was recently estimated to be 10%. CONCLUSION: The prevalence of PM in leprosy patients in western Kenya was lower than that in studies carried out in India. This could be attributed to de-institutionalisation and re-integration of leprosy sufferers back into their local communities. Since the rate was more than double that in the general Kenyan population and seemed to be related to presence of physical disability, an appraisal of psychiatric services offered to these patients is needed.

OBJECTIVE: To determine the pattern and characteristics of patients admitted with firearm injuries (FAIs) and establish the morbidity and mortality associated with these injuries. DESIGN: Retrospective cross-sectional study. SETTING: Kenyatta National Hospital (KNH), January 2004 to December 2005. SUBJECTS: All patients admitted with physically evident firearm injury. RESULTS: There were a total of 717 patients recorded with FAIs constituting 0.6% of the total number of patients seen in the casualty. Of these, 421 (58.7%) were admitted and treated as in- patients. A firearm was used in 6.7% of the 6300 assault cases recorded in 2004 and in 9.7% of the 3079 cases recorded in 2005. The increase from 6.7% in 2004 to 9.7% in 2005 was statistically significant (p < 0.05). There were 370 (87.9%) males and 49 (11.6%) females giving a male to female ratio of 7.5:1. The mean age was 29.7 +/- 10.9 years with a range of 3 to 66 years. At least 262 (62.2%) of the 421 admitted FAI casualties were treated under general anaesthesia (GA). The average duration of operation per patient was 2 +/- 1.5 hours. CONCLUSION: FAIs are on the increase and affect all age groups but is largely a disease of a young male adult in the 3rd and 4th decade of life. Mortality is higher with increasing age while female victims are fewer but on average six years younger than males. The lower extremities are the commonest target among the survivors. However, abdominal wounds tend to be the most lethal, accounting for greater mortality.

Abstract

OBJECTIVE: To study re-association pattern of human placental eluate immunoglobulins with acid treated isologous and third party trophoblast derived placental microvesicles. DESIGN: Laboratory based experimentation. SETTING: Biological Sciences Department and Discipline for Reproductive Medicine University of Newcastle, Australia and the Department of Biochemistry, University of Nairobi, Kenya. RESULTS: Placental eluate immunoglobulins re-associated with isologous and third party acidified microvesicles in three distinct patterns. I: eluate immunoglobulins re-associated more strongly with isologous and third party acid treated placental microvesicles, II: eluate immunoglobulins re-associated strongly with isologous but weakly with third party acid treated placental microvesicles, III: eluate immunoglobulins did not show preferential re-association with isologous and third party acid treated placental microvesicles. CONCLUSION: Two types of antigenic epitopes I and II may be expressed on the human placentae. Type I antigens may be present on all human placentae while type II epitopes may be paternally derived hence unique to each pregnancy. Also, immunoglobulins produced to placental microvesicle antigens may be directed to some but not all antigenic epitopes expressed on the human placental trophoblast.

BACKGROUND: The quality of life of cancer patients is likely to be influenced by psychological reactions of the cancer patients yet there are no documented issues related to quality of life in cancer patients in Kenyan hospitals. OBJECTIVE: To investigate issues which affect the quality of life in male cancer patients. DESIGN: Prospective cross sectional study. SETTING: Kenyatta National Hospital, Nairobi, Kenya. METHODS AND SUBJECTS: Cancer patients above 12 years of age were interviewed during the course of their stay in the hospital, specifically to gather information on; semi structured questions and a modified Beck's 24 item depression inventory with a view to solicit for their reaction on issues which pertains to quality of life. MAIN OUTCOME MEASURES: Age group, level of education, tribe, geographical place (province) of birth, chief complains, main concerns, views on doctors, contact with psychiatrist and psychologist, the anatomic site of cancer, treatment given and responses on modified Beck's depression inventory. RESULTS: Forty two patients were studied, their age range 13-72 years, mean 43.2 and peak 13-26 years. Forty seven per cent of cases had no formal education. The cancers were gastrointestinal tract 33%, blood and lymphoid tissue (26%), bone and muscle (11.9%), skin (9.4%) and genitourinary tract (4.8%). Treatment given was chemotherapy, radiotherapy and surgery. Ninety three per cent were unable to cope. Chief complaints were pain, inability to work, feeling miserable and concerns were families, health and work retardation. Modified Beck's depression score was 20%, with major issues being; work retardation, insomnia, weight loss, and anorexia. Most affected were, age group 27-35 years (and least 13-26 years), uneducated, living in Nairobi (city), having carcinomas, treatment with combined surgery and radiotherapy. Low education level and residence in Nairobi coped poorly. Radiation therapy group appeared to cope better than other modalities. CONCLUSION: The issues affecting the quality of life of male cancer patients stated were pain, inability to work, poor coping with cancer and psychological reactions of work retardation, insomnia, weight loss, fatigability and depression. Gambling, suicidal ideas and social withdrawal were minimal. Other concerns were families, health and work.

Resting metabolic rates have been measured and compared with hepatic mitochondrial respiration in Kwashiorkor and diet-induced obese weaned rats. In Kwashiorkor, resting metabolic rate was 21% lower than the value of controls, while that of the obese rats was 14% higher than in control animals. The resting metabolic rate for Kwashiorkor animals was 50% of the predicted basal metabolic rate (BMR), whereas that of the obese rats was 23% higher than the predicted BMR. The mitochondrial oxygen consumption patterns, using malate plus glutamate or succinate as respiratory substrates, revealed that the resting respiration (state 4) was 23.9% higher in Kwashiorkor and 29.1% higher in obese animals, while the active (state 3) respiration was 34.8% lower in Kwashiorkor and 43.3% lower in obese rats compared to controls. The respiratory control ratios (RCR) were 51.1% and 43.8% in Kwashiorkor and obese rats, respectively, relative to the values in control rats.

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.

Immunoglobulins were eluted from ovine placentae and characterized by immunoprecipitation, electrophoresis, western blotting and ELISA.IgG was shown to comprise the bulk of placental-bound immunoglobulins while smaller amounts of IgM and only trace amounts of IgA were demonstrated.Results suggest that ovine placental IgG eluted by surgical cannulation of the uterine blood vessels in situ is similar to that eluted from postpartum placentae in vitro, implying that there may be some transfer of antibodies across the maternal side of the placental barrier to the trophoblast.These antibodies are rich in IgG1 and IgG2, have a relative molecular weight of 158 kDa, and bind to an 80 kDa peptide prepared from pre-acidified ovine placental cotyledons.We propose that the binding of placental IgG to the 80 kDa antigen may prevent immunological rejection of the foetus by competitively excluding cytotoxic cells of maternal origin such as NK cells.Also, given that a similar antigen (80 kDa) has been reported in humans and equines, and shown to be saturated with IgG in term placentae, we propose that this antigen may be conserved in several mammalian species for reproductive purpose.Consequently, we suggest that the ovine placental IgG and the 80 kDa antigen may be suitable as models for the study of maternal-foetal interactions in mammalian pregnancies.

OBJECTIVE: To determine the prevalence of tardive dyskinesia among psychiatric in-patients. DESIGN: A cross-sectional survey. SETTING: Mathari Hospital, Nairobi, the main psychiatric referral hospital in Kenya. SUBJECTS: Two hundred and two randomly selected in-patients seen in the hospital between January and April 2000. RESULTS: The prevalence of tardive dyskinesia was 11.9%. Neither the psychiatric diagnosis nor the sex was significantly associated with tardive dyskinesia. The antipsychotic dosage was also not associated with tardive dyskinesia but an increase in age was significantly associated with the abnormal movements. CONCLUSION: The prevalence rate of tardive dyskinesia among patients at Mathari Hospital is much lower than that found in western countries but similar to that from Asian studies. These findings indicate the possibility of racial differences in the aetiology of TD. Prospective cross-racial studies are necessary to confirm these findings.

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.

Twenty variceal banding sessions were performed in eight patients between February 1995 and September 1996. A total of 69 rings were used to band the varices and at each session between two to six rings were used. Two of the eight had active bleeding and both underwent variceal banding to successfully arrest their bleeding as inpatients. Sixteen other variceal banding sessions were performed on an outpatient basis to obliterate their varices. Four of the eight patients had had sclerotherapy before and varices were still present. No acute or long term complications were noted. In one patient, variceal banding could not be performed as he developed stridor upon placement of the overtube. All the patients had advanced varices (Grade III or IV) and extended for more than 15 cms in the oesophagus. Endoscopic variceal obliteration remains the treatment of choice for patients with portal hypertension with variceal bleeding. Variceal banding is associated with a superior outcome when compared with sclerotherapy; the variceal kill time is shorter, infective complications less, rebleeding occurs less commonly and transfusion requirements are lower.

The unexpected failure of the mother to immunologically reject the foetus is partly thought to result from immunological properties of the placenta. The placental trophoblast produces immunosuppressive factors including progesterone and blocking antibodies which together down-regulate maternal immune responses to the foetoplacental unit. This article reviews the post implantation immunology of pregnancy emphasizing the roles of placenta, blocking factors and natural killer (NK) cells.

Background: Accurate evaluation of low back pain is essential for its rational management. The extent of use of clinical and imaging findings in identificationof prolapsed intervertebral disk varies between centers. In Kenya, thediagnostic procedure is obscure.Objective: To assess the evaluation of low back pain patients for prolapsed intervertebral disk at a Kenyatta National Hospital, a teaching and referralhospital in Kenya.Study Design: A retrospective chart studyPatients and Methods: Historical, physical and imaging findings of patients who presented with low back pain and subsequently diagnosed with prolapsed inter-vertebral disk between Jan 1997 and December 2007 were evaluated.Results: Of the six hundred and three patients (267 males, 336 females) whowere evaluated, risk factors were recorded in 39.5% patients, 35.3%patients had sciatica while straight leg raising test was performed in52.2% patients. Investigations performed in these patients included plainroentograms (38.5%), CT scan (9.1%) and MRI (44.1%).Conclusion: The evaluation of low back pain for prolapsed inter-vertebral disk was incomplete. History of sciatica, SLRT, crossed SLRT and MRI use arerecommended for routine evaluation of low back pain for PID.

Knowledge of the variant vascular anatomy of the subhepatic region is important for hepatobiliary surgeons in limiting operative complications due to unexpected bleeding. The pattern of arterial blood supply of 102 gallbladders was studied by gross dissection. The cystic artery originated from the right hepatic artery in 92.2% of cases. The rest were aberrant and originated from the proper hepatic artery. Accessory arteries were observed to originate from proper hepatic artery (n = 5), left hepatic artery (n = 2), and right hepatic artery (n = 1). Most of the arteries approached the gallbladder in relation to the common hepatic duct (anterior 45.1%, posterior, 46.1%). The other vessels passed anterior to common bile duct (2.9%), posterior to common bile duct (3.9%), or were given off in Calot's triangle. Cystic arteries in this data set show wide variations in terms of relationship to the duct systems. In about one tenth of patients, an accessory cystic artery may need to be ligated or clipped during cholecystectomy. 2007 Wiley-Liss, Inc

OBJECTIVE: To determine the accuracy and sensitivity of diagnostic peritoneal lavage in the assessment of intra-abdominal injury using the dipstick method. DESIGN: Prospective study, involving the performance of diagnostic peritoneal lavage in the out patient department and surgical wards prior to surgical intervention. SETTING: Kenyatta National Hospital-General Surgical and Orthopaedic wards and outpatient department. The study was conducted over a duration of six months, starting from January 1995 to July 1995. RESULTS: Ninety six patients with penetrating (68) and blunt (28) abdominal trauma underwent diagnostic peritoneal lavage as evaluation of the severity of abdominal trauma. Dipstick (combur 9 strips) was used to evaluate lavage effluent for red blood cells, white blood cells, protein and bilirubin. Forty three patients had positive diagnostic peritoneal lavage (DPL) results, of which 40 (93%) had positive findings at laparatomy and three (7%) had negative findings at laparatomy. The remaining 53 patients had negative DPL results and were managed conservatively. One patient with a negative DPL result became symptomatic and had a positive laparatomy. Conservatively managed patients were discharged after 24 hours observations without any complications. DPL had an accuracy and sensitivity of 93% and specificity of 98%. CONCLUSION: Diagnostic peritoneal lavage is a cheap, safe and reliable method for assessment of abdominal trauma. The method is easy to perform by trained junior doctors in the OPD, or as a bedside procedure. Use of this method reduced negative laparotomy rate from 50% to 6.9% and average duration of stay from 6.5 days to 1.9 days. This method is recommended as a basic tool in the assessment of abdominal trauma patients.

Aerobic and facultative bacterial isolates from blood cultures of children with clinically diagnosed septicaemia.East Afr Med J. 1991 Nov;68(11):869-74.". In: East Afr Med J. 1991 Nov;68(11):869-74. IBIMA Publishing; 1991. Abstract
A total of 120 sets of blood cultures were performed aerobically from 60 children with clinically diagnosed septicaemia at Kenyatta National Hospital, Nairobi. Out of these, 36 (30%) sets from 19 (31.7%) patients yielded bacterial growth while 84 (70%) sets from 41 (68.3%) were negative. Salmonella typhimurium was the most frequently isolated bacteria (63%), followed by Staphylococcus aureus (15.8%). Salmonella typhimurium isolates were mostly multi-antibiotic resistant, most of them only sensitive to amikacin and cefotaxime, while all were resistant to ampicillin and co-trimoxazole, the most frequently used antibiotic in this hospital. PIP: Between March 1987-January 1988, physicians enrolled 60 pediatric patients with a fever who were admitted to the Kenyatta National Hospital in Nairobi, Kenya for various clinical conditions in a study to determine the types, frequency, and antibiotic sensitivity patterns of aerobic and facultative bacterial isolates. Most of the patients were 13 months-4 years old (45%). 31.7% of the patients had positive blood cultures. Staphylococcus aureus was the 2nd most common bacteria (15.8%) among these patients. Laboratory personnel isolated Salmonella typhimurium in most patients (63%). In fact, during the same period, the Diagnostic Microbiology Laboratory at the hospital identified Salmonella species in 48% of all isolated bacteria and 35% of these were S. typhimurium. S. typhimurium tended to be present in children with gastroenteritis (41.8%) or a fever of unknown origin (33.3%). S. typhimurium was very sensitive to amikacin and cefotaxime, but resistant to ampicillin and sulfamethoxazole-trimethoprim. Health workers in Kenya have frequently administered ampicillin and sulfamethoxazole-trimethoprim, but not amikacin and cefotaxime. 67% of the strains of S. typhimurium were resistant to gentamicin and 33% to chloramphenicol. These results along with those of other reports from this hospital indicated a dramatic rise in Gram negative bacteria resistance to antibiotics. Therefore physicians should no longer consider gentamicin as a 1st line antibiotic in treating suspected septicemia patients.

A retrospective study of 42 patients with perforations of the oesophagus during the period 1981-1987 indicated that 57.1% of the perforations were iatrogenic. Diseases of the oesophagus and in contiguous structures and foreign bodies in the oesophagus caused perforations in 31% of the cases. Perforations in 35.7% of the patients were located in the middle third of the oesophagus. The lower and upper thirds were affected in 31% of the patients in each site. The presenting physical signs included tachycardia (78.6%), fever (76.2%) and dyspnoea (59.5%). The main accompanying symptoms were chest pain and coughs in 100% and in 50% of the patients respectively. Radiographic findings showed hydropneumothorax in 40.5% of the cases and consolidation in 38.1% of the patients. Oesophagoscopy was positive in 78% of cases tested while thoracocentesis was positive in all cases that were tested.

OBJECTIVE: To determine the bacteriology and antibiotic sensitivity of the bacterial isolates in chronic maxillary sinusitis patients seen at the Kenyatta National Hospital. DESIGN: Cross-sectional study. SETTING: Kenyatta National Hospital, ENT department. SUBJECTS AND METHODS: Seventy-three patients had bilateral sntral washout done and the lavage submitted for culture and anti-microbial sensitivity between January and June 1996. RESULTS: Antral lavage yielded secretions in 63% of patients but bacteria were cultured in only 28.8% of the specimens. The isolates included Streptococcus pneumonia (22.2%), Staphylocococus albus (18.5%), Staphylocococus aureus (11.1%) and Enterobactericiae (11.1%). Anaerobic bacteria were cultured in 22.2% of the specimens. Of the commonly used antibiotics, there was high sensitivity to erythromycin, cefadroxyl, chloramphenicol and amoxicillin and poor sensitivity to ampicillin, cotrimoxazole and perfloxacin. CONCLUSION: The bacteriology of chronic maxillary sinusitis at Kenyatta National Hospital is generally similar to that found elsewhere. The bacteria are susceptible to relatively affordable antibiotics like amoxicillin, erythromycin and cefadroxyl.

Knowledge of the variant vascular anatomy of the subhepatic region is important for hepatobiliary surgeons in limiting operative complications due to unexpected bleeding. The pattern of arterial blood supply of 102 gallbladders was studied by gross dissection. The cystic artery originated from the right hepatic artery in 92.2% of cases. The rest were aberrant and originated from the proper hepatic artery. Accessory arteries were observed to originate from proper hepatic artery (n = 5), left hepatic artery (n = 2), and right hepatic artery (n = 1). Most of the arteries approached the gallbladder in relation to the common hepatic duct (anterior 45.1%, posterior, 46.1%). The other vessels passed anterior to common bile duct (2.9%), posterior to common bile duct (3.9%), or were given off in Calot's triangle. Cystic arteries in this data set show wide variations in terms of relationship to the duct systems. In about one tenth of patients, an accessory cystic artery may need to be ligated or clipped during cholecystectomy. 2007 Wiley-Liss, Inc

Background: Prolapsed intervertebral disk (PID) disease can be managed conservatively or surgically with different reported outcomes.Objective: The present study aimed at assessing the management and outcomes of slipped intervertebral disk disease at the Kenyatta National hospital.Study Design: A retrospective cross-sectional study.Setting: Kenyatta National Hospital (KNH) a referral and teaching Hospital in Kenya.Patients and Methods: Consecutive files of all cases of slipped intervertebral disk disease from January1997 to December 2007 were retrieved from the Medical records at the Kenyatta National Hospital. The biodata, management methods and the outcomes of the procedures were recorded. The collecteddata was analyzed using the SPSS 17.0 for Windows.Results: Six hundred and three cases were reviewed. All patients received analgesics and bed rest.Five percent of the patients were put on bilateral traction for two weeks while 4% of the patients had corsets. Thirty five per cent of the patients were surgically managed. Over a third of the surgically managed patients had laminectomies. Microdiscectomy was increasingly popular in the latter half ofthe study period. Of the managed patients 95% reported improvement while 92% were complication free. The rate of reherniation and reoperation was 1.5% and 1.2% respectively.Conclusion: The management of PID at Kenyatta National Hospital is largely successful with few cases of complications. In selected patients both conservative and surgical care are used in tandem. Microdiscectomy is an increasingly popular surgical procedure at the KNH.

SETTING: Kenyatta National Hospital-General Surgical and Orthopaedic wards and outpatient department. The study was conducted over a duration of six months, starting from January 1995 to July 1995. RESULTS: Ninety six patients with penetrating (68) and blunt (28) abdominal trauma underwent diagnostic peritoneal lavage as evaluation of the severity of abdominal trauma. Dipstick (combur 9 strips) was used to evaluate lavage effluent for red blood cells, white blood cells, protein and bilirubin. Forty three patients had positive diagnostic peritoneal lavage (DPL) results, of which 40 (93%) had positive findings at laparatomy and three (7%) had negative findings at laparatomy. The remaining 53 patients had negative DPL results and were managed conservatively. One patient with a negative DPL result became symptomatic and had a positive laparatomy. Conservatively managed patients were discharged after 24 hours observations without any complications. DPL had an accuracy and sensitivity of 93% and specificity of 98%. CONCLUSION: Diagnostic peritoneal lavage is a cheap, safe and reliable method for assessment of abdominal trauma. The method is easy to perform by trained junior doctors in the OPD, or as a bedside procedure. Use of this method reduced negative laparotomy rate from 50% to 6.9% and average duration of stay from 6.5 days to 1.9 days.

A retrospective study of 42 patients with perforations of the oesophagus during the period 1981-1987 indicated that 57.1% of the perforations were iatrogenic. Diseases of the oesophagus and in contiguous structures and foreign bodies in the oesophagus caused perforations in 31% of the cases. Perforations in 35.7% of the patients were located in the middle third of the oesophagus. The lower and upper thirds were affected in 31% of the patients in each site. The presenting physical signs included tachycardia (78.6%), fever (76.2%) and dyspnoea (59.5%). The main accompanying symptoms were chest pain and coughs in 100% and in 50% of the patients respectively. Radiographic findings showed hydropneumothorax in 40.5% of the cases and consolidation in 38.1% of the patients. Oesophagoscopy was positive in 78% of cases tested while thoracocentesis was positive in all cases that were tested.

This paper looks at the beginnings of cardiac surgery in Kenya with relevant clinical data as well as the overall historical background to various cardiovascular operations which preceded formal establishment of the Thoracic and Cardiovascular Surgical Unit at the Kenyatta National Hospital. Similar activities in other hospitals in Nairobi and elsewhere in Kenya have been excluded. The Unit separated from general surgical wards in January 1973. By the end of 1983, a total of 208 open heart operations had been done by various teams in the Unit. A number of other heart operations were also undertaken. Those done before that decade are also highlighted back to 1950. The many problems that the Unit faced and still faces are also identified in this paper and the dream of making it a Centre of Excellence revisited.

The pattern of arterial blood supply of 102 gallbladders was studied by gross dissection. The cystic artery originated from the right hepatic artery in 92.2% of cases. The rest were aberrant and originated from the proper hepatic artery. Accessory arteries were observed to originate from proper hepatic artery (n = 5), left hepatic artery (n = 2), and right hepatic artery (n = 1). Most of the arteries approached the gallbladder in relation to the common hepatic duct (anterior 45.1%, posterior, 46.1%). The other vessels passed anterior to common bile duct (2.9%), posterior to common bile duct (3.9%), or were given off in Calot's triangle. Cystic arteries in this data set show wide variations in terms of relationship to the duct systems. In about one tenth of patients, an accessory cystic artery may need to be ligated or clipped during cholecystectomy. 2007 Wiley-Liss, Inc

Background: Accurate evaluation of low back pain is essential for its rational management. The extent of use of clinical and imaging findings in identificationof prolapsed intervertebral disk varies between centers. In Kenya, thediagnostic procedure is obscure.Objective: To assess the evaluation of low back pain patients for prolapsed intervertebral disk at a Kenyatta National Hospital, a teaching and referralhospital in Kenya.Study Design: A retrospective chart studyPatients and Methods: Historical, physical and imaging findings of patients who presented with low back pain and subsequently diagnosed with prolapsed inter-vertebral disk between Jan 1997 and December 2007 were evaluated.Results: Of the six hundred and three patients (267 males, 336 females) whowere evaluated, risk factors were recorded in 39.5% patients, 35.3%patients had sciatica while straight leg raising test was performed in52.2% patients. Investigations performed in these patients included plainroentograms (38.5%), CT scan (9.1%) and MRI (44.1%).Conclusion: The evaluation of low back pain for prolapsed inter-vertebral disk was incomplete. History of sciatica, SLRT, crossed SLRT and MRI use arerecommended for routine evaluation of low back pain for PID.

OBJECTIVE: To determine the accuracy and sensitivity of diagnostic peritoneal lavage in the assessment of intra-abdominal injury using the dipstick method. DESIGN: Prospective study, involving the performance of diagnostic peritoneal lavage in the out patient department and surgical wards prior to surgical intervention. SETTING: Kenyatta National Hospital-General Surgical and Orthopaedic wards and outpatient department. The study was conducted over a duration of six months, starting from January 1995 to July 1995. RESULTS: Ninety six patients with penetrating (68) and blunt (28) abdominal trauma underwent diagnostic peritoneal lavage as evaluation of the severity of abdominal trauma. Dipstick (combur 9 strips) was used to evaluate lavage effluent for red blood cells, white blood cells, protein and bilirubin. Forty three patients had positive diagnostic peritoneal lavage (DPL) results, of which 40 (93%) had positive findings at laparatomy and three (7%) had negative findings at laparatomy. The remaining 53 patients had negative DPL results and were managed conservatively. One patient with a negative DPL result became symptomatic and had a positive laparatomy. Conservatively managed patients were discharged after 24 hours observations without any complications. DPL had an accuracy and sensitivity of 93% and specificity of 98%. CONCLUSION: Diagnostic peritoneal lavage is a cheap, safe and reliable method for assessment of abdominal trauma. The method is easy to perform by trained junior doctors in the OPD, or as a bedside procedure. Use of this method reduced negative laparotomy rate from 50% to 6.9% and average duration of stay from 6.5 days to 1.9 days. This method is recommended as a basic tool in the assessment of abdominal trauma patients.

In: Trop Med Int Health. 2005 May;10(5):484-8. IBIMA Publishing; 2005. Abstract
Sulphadoxine/pyrimethamine (SP) is often administered with quinine in the treatment of severe falciparum malaria to shorten the course of quinine. The efficacy of SP alone in the treatment of non-severe malaria has been declining rapidly in East Africa, raising concerns of the usefulness of a shortened course of quinine followed SP. We audited the efficacy of quinine/SP in the treatment of severe malaria in Kenyan children. Children with severe falciparum malaria were treated with parenteral quinine followed by a single oral dose of SP. A clinical evaluation was performed 3 weeks later in which a blood sample was obtained for full haemogram, blood slide and analysis of the parasite dihydrofolate reductase (DHFR) and dihydropteroate synthase (DHPS) codons, mutations of which are associated with resistance to SP. A total of 452 children were enrolled, of whom 374 completed the study. Fifty-two (13.9%) children were parasitaemic by 3 weeks of whom 17 (4.5%) had fever as well. The treatment failure group had a significantly higher parasitaemia (129 061 vs. 43 339; P<0.001) and haemoglobin on admission, but only admission parasitaemia independently predicted treatment failure. Those with treatment failure had a significantly lower rise in haemoglobin at 3 weeks compared with treatment successes (9.0 vs. 10.0 g/dl). Of the 76 parasite isolates collected before treatment, 40 (53%) were triple mutant DHFR-double DHPS (Tp-Db), the genotype most associated with SP resistance. Three weeks after SP treatment, the proportion of Tp-Db increased to 72% (31/43). The high treatment failure rate and proportion of parasites with Tp-Db negate the use of SP to shorten the course of quinine treatment in East Africa.

A retrospective study of 42 patients with perforations of the oesophagus during the period 1981-1987 indicated that 57.1% of the perforations were iatrogenic. Diseases of the oesophagus and in contiguous structures and foreign bodies in the oesophagus caused perforations in 31% of the cases. Perforations in 35.7% of the patients were located in the middle third of the oesophagus. The lower and upper thirds were affected in 31% of the patients in each site. The presenting physical signs included tachycardia (78.6%), fever (76.2%) and dyspnoea (59.5%). The main accompanying symptoms were chest pain and coughs in 100% and in 50% of the patients respectively. Radiographic findings showed hydropneumothorax in 40.5% of the cases and consolidation in 38.1% of the patients. Oesophagoscopy was positive in 78% of cases tested while thoracocentesis was positive in all cases that were tested.

Background: Prolapsed intervertebral disk (PID) disease can be managed conservatively or surgically with different reported outcomes.Objective: The present study aimed at assessing the management and outcomes of slipped intervertebral disk disease at the Kenyatta National hospital.Study Design: A retrospective cross-sectional study.Setting: Kenyatta National Hospital (KNH) a referral and teaching Hospital in Kenya.Patients and Methods: Consecutive files of all cases of slipped intervertebral disk disease from January1997 to December 2007 were retrieved from the Medical records at the Kenyatta National Hospital. The biodata, management methods and the outcomes of the procedures were recorded. The collecteddata was analyzed using the SPSS 17.0 for Windows.Results: Six hundred and three cases were reviewed. All patients received analgesics and bed rest.Five percent of the patients were put on bilateral traction for two weeks while 4% of the patients had corsets. Thirty five per cent of the patients were surgically managed. Over a third of the surgically managed patients had laminectomies. Microdiscectomy was increasingly popular in the latter half ofthe study period. Of the managed patients 95% reported improvement while 92% were complication free. The rate of reherniation and reoperation was 1.5% and 1.2% respectively.Conclusion: The management of PID at Kenyatta National Hospital is largely successful with few cases of complications. In selected patients both conservative and surgical care are used in tandem. Microdiscectomy is an increasingly popular surgical procedure at the KNH.

Twenty variceal banding sessions were performed in eight patients between February 1995 and September 1996. A total of 69 rings were used to band the varices and at each session between two to six rings were used. Two of the eight had active bleeding and both underwent variceal banding to successfully arrest their bleeding as inpatients. Sixteen other variceal banding sessions were performed on an outpatient basis to obliterate their varices. Four of the eight patients had had sclerotherapy before and varices were still present. No acute or long term complications were noted. In one patient, variceal banding could not be performed as he developed stridor upon placement of the overtube. All the patients had advanced varices (Grade III or IV) and extended for more than 15 cms in the oesophagus. Endoscopic variceal obliteration remains the treatment of choice for patients with portal hypertension with variceal bleeding. Variceal banding is associated with a superior outcome when compared with sclerotherapy; the variceal kill time is shorter, infective complications less, rebleeding occurs less commonly and transfusion requirements are lower.

Samples of water, sediments and aquatic weeds were collected from 26 sites in the Nyando River catchment of the Lake Victoria basin in 2005–2006. The objective was to investigate levels of organochlorine pesticides that have either been banned or are restricted for use in Kenya. The pesticides investigated were lindane, aldrin, endosulfan, endrin, dieldrin, DDT, heptachlor and methoxychlor. These pesticides had previously found wide applications in public health and agriculture in Kenya for control of disease vectors and crop pests respectively. Results showed that mean concentrations were highest for methoxychlor (8.817 ± 0.020 µg l−1) in water, sediments (92.893 ± 3.039 µg kg−1), and weeds (39.641 ± 3.045 µg kg−1), the weeds also tended to accumulate aldrin (15.519 ± 3.756 µg kg−1). The results show that the pesticides are still in use and are detected in the catchment. Stringent management and public awareness measures are required to enforce the ban on the organochlorine pesticides in order to safeguard the environment and ecosystems of Lake Victoria.

The study was to investigate the impacts on the ecosystem health in relation to levels and distribution of organochlorine pesticides that have either been banned or restricted for use in Kenya. The pesticides targeted were DDT, lindane, aldrin, dieldrin, heptachlor, endrin, endosuphan, and methoxychlor. Prior to their ban or restriction in use, they had found wide applications in public health and agriculture for control of disease vectors and crop pests respectively.

A study was conducted in which 880 samples of soil, water, sediments, aquatic weeds and benthic macroinvertebrates were collected from 26 locations representative of the River Nyando drainage basin catchment area of 3450 km2 and a total length of 170 km of the Lake Victoria Catchment over a period of two years. Soils from six farms were sampled in areas where maize, tea, sugar cane, col fee, rice and vegetables have been grown over the years. The objective was to investigate the impacts on the ecosystem health in relation to levels and distribution of oraganochlorine pesticides that have either been banned or are restricted for use in Kenya. The pesticides targeted were DDT, lindane, aldrin, dieldrin, heptachlor, endrin, endosulfan and methoxychlor. Pior to their ban or restriction in use, they had found wide applications in public health and agriculture for control of disease vectors and crop pests respectively. Analysis of 48 soil samples revealed presence of all the targeted pesticides. Mean concentrations (pg/kg) recorded decreased in the order methoxychlor (138.97±1.517 pg/kg), total (X) endosulfan (30.267±2.098pg/kg), £DDT (17.513± 1.689 pg/kg), dieldrin (14.073±0.440 pg/kg), endrin (10.155±0.860 pg/kg), lindane (8.985±1.318 pg/kg) and ^Heptachlor (0.681±0.021 pg/kg), respectively. The distribution showed that dieldrin was in use in vegetable farms in Kedowa area, tea farms in Nandi District and in Ahero rice paddies; while p-endosulfan was commonly used on tea farms in Nandi. Water analysis from the 26 sampling sites showed the highest mean concentrations were detected for methoxychlor (8.817±0.020 pg/L), ^endosulfan (1.648± 0.04 pg/L), dieldrin (1.1561± 0.042 pg/L), endrin (0.281± 0.003 pg/L), £DDT (0.242±0.009 pg/L), £heptachlor (0.148±0.01 lpg/L) and lindane (0.144±0.006pg/L) respectively. The detected levels in sediments were considerably higher than those found in water in the order, methoxychlor (92.893±3.039 pg/kg ), lindane (33.917±2.360 pg/kg), aldrin (26.676±0.981 pg/kg ), dieldrin (23.62±4.810 pg/kg) and P-endosulfan, (10.502±0.800 pg/kg), respectively. The analysis of aquatic weeds recorded methoxychlor (39.641±3.045 pg/kg) as the highest residue concentrations, followed by aldrin (15.519±3.756 pg/kg). These higher levels may be as a result of continued use of the pesticide in the drainage basin. The levels of pesticides were higher in sediment, weeds and soil than in water. The pooled results show that the targeted pesticides are still in use in the basin and could be impacting negatively on the ecosystem health of the area. A study of the composition of the benthic macroinvertebrates showed presence of four invertebrate phyla in River Nyando. These were Arthropoda, Mollusca, Plathelminthes and Annelida. A diversity of 16 families and eleven orders was recorded, with the order Ephemeroptera being abundant upstream followed by Hemiptera, Plecoptera and Trichoptera respectively. The downstream sections mainly the rice farming areas were dominated by Hirudinae (leaches) and Oligochaeta, suggesting that they are less sensitive to environmental pollution. Using Multivariate analytical techniques, Redundancy Analysis and Canonical Correspondence Analysis, correlation statistics showed that the occurrence of organochlorine pesticides strongly affects the distribution of the benthic macro invertebrates at all the sampling locations within the drainage basin. The high concentrations of pesticide residues were detected mostly in the soils and water from rice farms, these magnitudes were followed by those from tea farms. This implies that the rice farmers use most pesticides followed by tea farmers and there the proximity of the rice paddies to Lake Victoria could pose a greater impact to ecosystem health in the entire catchment than the upstream tea, sugar cane, maize and coffee farms owing to pesticide discharge; and this call for stringent management measures to be put in place to safeguard the environment.

Description
A baseline study was conducted of the occurrence of macroinvertebrates at 26 sites in the Nyando River catchment in 2005–2006. A total of 13 orders and 16 families of Arthropoda, Mollusca, Platyhelminthes and Annelida were collected, with the order Ephemeroptera being most abundant in the up- and mid-stream reaches, followed by Hemiptera and Plecoptera respectively. The downstream sections of the river were dominated by Hirudinea and tubificids, as the water quality deteriorated mainly due to local land use, raw sewage effluent discharge and annual floods. Insects and annelids were the main invertebrates found and the extent of pollution increased from mid-section (Site 15) downwards as the river flowed into the Winam Gulf. Stringent management measures are required to safeguard the environment and ecosystems of Lake Victoria.

Presented here is a 16-year-old girl who was referred on 30th January 1996 with diagnosis of cord compression with spastic paraplegia with sensory level at T7/T8. CT scan myelogam confirmed soft tissue density mass displacing cord to the left with no dye being seen beyond T3. Thoracic spine decompressive laminectomy was performed on 1st January 1996 at Nairobi West Hospital extending from T3 to T6 level, which revealed a fibrous haemorrhagic tumour. Histology showed meningioma (mixed fibrous type and meningoepitheliomatous type) with many psammoma bodies. She had a stormy post-operative period, with infection and wound dehiscence. This was treated with appropriate antibiotics and wound care. She was eventually rehabilitated and was able to walk with the aid of a walking frame because of persistent spasticity of right leg. She was seen once as an outpatient by author on 6th July 1996, she was able to use the walking frame, but the right leg was still held in flexion deformity at the knee. She was thus referred to an orthopaedic surgeon for possible tenotomy. She was able to resume her studies at the University ambulating using a wheel chair and walking frame. She presented with worsening of symptoms in 2001 (five years after her first surgery). MRI scan thoracic spine revealed a left anterolateral intradural lesion extending from T3 to T5 vertebral body level compressing and displacing the spinal cord. She had a repeat surgery on 6th March 2001 at Kenyatta National Hospital; spastic paraparesis and urinary incontinenece persisted. She also developed bed sores and recurrent urinary tract infections. She was followed up by the author and other medical personnel in Mwea Mission Hospital where she eventually succumbed in 2005, nine years after her first surgery. This case is presented as a case of incompletely excised spinal meningioma to highlight some of the problems of managing spinal meningiomas when operating microscope and embolisation of tumours are not readily available. Also the family experienced financial constraint in bringing the patient for regular follow-up, and getting access to appropriate antibiotics, catheters and urine bags.

In: East Afr J Public Health. 2008 Apr;5(1):1-5. Karimurio Jefitha; Rono Hillary; Richard Le Mesurier; Mutuku Mwanthi; Jill Keeffe; 2008. Abstract
OBJECTIVE: This study assessed the role of governmental and non-governmental organizations in mitigation of stigma and discrimination among people infected and affected by HIV/AIDS in informal settlements of Kibera. METHODS: This was a descriptive cross-sectional study and used a multi stage stratified sampling method. The study was conducted in Kibera, an informal settlement with a population of over one million people which makes it the largest slum not only in Kenya but in sub-Saharan Africa. The study targeted infected individuals, non-infected community members, managers of the organizations implementing HIV/AIDS programmes and service providers. In the process 1331 households were interviewed using qualitative and quantitative data collection instruments. Statistical Package for Social Sciences (SPSS) and Nudist 4 packages were used to analyze the quantitative and qualitative data respectively. RESULTS: More than 61% of the respondents had patients in their households. Fifty five percent (55%) of the households received assistance from governmental and non-governmental organizations in taking care of the sick. Services provided included awareness, outreach, counseling, testing, treatment, advocacy, home based care, assistance to the orphans and legal issues. About 90% of the respondents perceived health education, counseling services and formation of post counseling support groups to combat stigma and discrimination to be helpful. CONCLUSION: Stigma and discrimination affects the rights of People Living with HIV/AIDS (PLWHAs). Such stigmatization and discrimination goes beyond and affects those who care for the PLWHAs, and remains the biggest impediment in the fight against HIV/AIDS in Kibera. Governmental and non-governmental organizations continue to provide key services in the mitigation of stigma and discrimination in Kibera. However, personal testimonies by PLWHAs showed that HIV positive persons still suffer from stigma and discrimination. Approximately 43% of the study population experienced stigma and discrimination.

In: East Afr Med J. 2005 Oct;82(10):501-5. Karimurio Jefitha; Rono Hillary; Richard Le Mesurier; Mutuku Mwanthi; Jill Keeffe; 2002. Abstract
BACKGROUND: Butere-Mumias district is one of the districts which performs poorly on immunisation coverage, as observed from the Kenya Expanded Programme of Immunisation reports. OBJECTIVE: To identify factors that contribute to the low level of immunisation coverage in the district among children under the age of five years. DESIGN: Cross-sectional descriptive study. SETTING: Butere-Mumias district. RESULTS: Out of the 293 mothers who were sampled, 238 (80%) had attained primary level of education while, 55 (20%) attained secondary level and above. Immunisation coverage was found to be 35% in this district. Long distances to health facilities, poor states of the roads, age, attitude and knowledge regarding immunisation among mothers were significant factors that determined immunisation coverage. CONCLUSION: Low levels of education, long distances to the nearest health facilities, lack of knowledge on immunisations and lack of staff were responsible for the low coverage. There is therefore, need to act on these factors which hamper the immunisation coverage in order to reduce child mortality rate which are attributable to non-immunisation.

Abstract
Kenyan communities are exposed to natural disasters by an amalgamation of factors such as poverty, aridity, and settlements in areas susceptible to natural disasters or in areas with poor infrastructure. This is expected to increase due to the effects of climate change. In an attempt to explain some of these variabilities, we model the extreme damages from natural disasters in Kenya by developing a compound distribution that takes into account both the frequency and the severity of the extreme events. The resulting distribution is based on a threshold model and compound extreme value distribution. For frequency of events exceeding a threshold of 150,000, we found that it follows a negative binomial distribution, while severity of exceedance follows a generalized Pareto distribution. This distribution fits the data well and is found to be a better model for natural disasters in Kenya than the traditional extreme value threshold model.

Staphylococcus aureus (S. aureus) (ATCC25923), Escherichia coli (E. coli) 0157:H7 (PSSCMI 0032), Bacillus subtillus, Candida albicans and Asparagus niger were used as test organisms. The water extract lacked significant activity against all organisms except Staphylococcus. aureus where the water extract exhibited the highest activity. However, the ethanol extract had significant activity against Candida albicans and Asperigillus niger with minimuminhibitory values of 58.59 and 14.65 μg/ml respectively. Methanol had high Minimum Inhibitory Concentration (MIC) values of less than 14.65 and 14.7 μg/ml for Asperigillus niger and E. coli respectively. From the results it was concluded that activity varied with the solvent used. Contrary to previous reports, the plant seems to lack significant antibacterial activity except against E. coli. The popularity of a herbal recipe is not always a measure for its potency. However, M. whytei had antifungal activity since the ethanol and methanol extracts showed significant activity against the tested strains of fungi. The antioxidant activity of the extracts was also evaluated using the DPPH free radical scavenging assay. M. whytei exhibited substantial inhibition of the DPPH activity with EC50 of 413 mg/l for the crude extracts. The results suggest that M. whytei has significant antioxidant activity as demonstrated by the DPPH assay. This antioxidant activity of the crude extracts can be attributed to the presence of 2-Hydroxy-4-Methoxybenzaldehyde that is a known antioxidant in the root extracts.  Key words: Aqueous, ethanol extract, methanol extract

Atinga JE, Kireti VM. "Osgood Schlatter disease: An Audit Profile of 35 Adolescents." The Annals of African Surgery, . 2010;6. Abstract

Background
Osgood-Schlatter disease is a common cause of anterior knee pain in the adolescent. Treatment is usually conservative with surgery reserved for those who do not respond to this treatment. There is little published work regarding the experience with the disease in our local set up. This series documents the experience with 35 adolescents treated for the disease.

Design
Case series

Subjects
Thirty five adolescents with clinical and radiological diagnoses of Osgood-Schlatter disease at Nairobi and Kenyatta National Hospitals, between 2001and 2007.

Method
Patients were evaluated for demographics, knee involvement, activities associated with pain and treatment outcome

Results
There were 28 males and 7 females, aged 10 to 16 years (mean 12.8 years). Thirteen had bilateral knee involvement. Twenty two were involved in active sports while the rest had constant pain and unable to sit or kneel. A family history of the disease was documented in one case. Thirty adolescents responded well to the conservative treatment. In the five adolescents who underwent surgery, the patella tendon was edematous with thickening of the tendon sheath and neovascularisation. All the operated adolescents returned to active sports with 6 weeks after the surgery.

Conclusion
Osgood-Schlatter disease is a self-limiting condition in majority of adolescents. Surgery when indicated has an excellent outcome.
