Operations Research techniques involving modelling a situation or a problem and finding an optimal solution for it. These tools are not designed nor intended to replace managerial decision making, but rather their purpose is to aid in the decision-making process by providing a quantitative basis for decision making. Unfortunately, the proliferation of OR tools in organizational decision making has been lacking, with concerns been expressed about the limited awareness of the business community of OR's potential and capability. Current study was based in the premise that students provide an appropriate avenue, as agent of change, in sensitizing and demonstrating the potential and capacity of OR tools/techniques in resolving various problems, both in public and private sector. Study aimed at evaluating the use of OR as tools of data analysis at MBA level. A sample of 100 MBA research projects undertaken between 2005 and 2007 was randomly selected and their objectives and selected data analysis tools recorded. Where OR tools were not used, the research evaluated if there was a possibility of using OR tools. Results indicated low usage of OR as data analysis, though there was a high potential for the use of OR tools.

In: International Plant Genetic Resources Institute Newsletter for Sub-Saharan Africa, Issue 17Rome, Italy. Canadian Center of Science and Education; 2000. Abstract
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.

In: Lecture Series presented during the Training of Trainers (TOT) for School Administrators inNasir, Sudan. DR. MARK NELSON AWORI; PROF. PANKAJ G. JANI; 1992. Abstract
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.

Kamau RK, Osoti AO, Njuguna EM. Department of Obstetrics and Gynaecology, College of Health Sciences, University of Nairobi, P.O. Box 1%76-00202, Nairobi, Kenya. BACKGROUND: Cancer of the uterine cervix is the most common female cancer in Kenya. Despite being preventable, it is often diagnosed when it is already late. For this reason, only palliative therapy is provided. Hence, it is expected that their daily routines and that of their caregivers are severely disrupted. OBJECTIVES: To determine the extent to which diagnosis and treatment of inoperable cervical carcinoma affects quality of life (QOL). DESIGN: Cross-sectional descriptive study. Setting Radiotherapy Department at the Kenyatta National Hospital. SUBJECTS: Women undergoing radiotherapy for inoperable cervical cancer. RESULTS: There is high prevalence of profound disruptions in nearly all domains of QOL. In the social domain, between 33% and 44% had the perception that family members and friends had withdrawn social support. Reduction in various economic facets was reported by 47.4%-52.6%, with 44.7% reporting a fall in the overall living standards. There were significant changes in the sexual domain, as a result in which 28.3% reported marital discordance. In the personality domain, decreased self-esteem and self-projection in life occurred in 30.9% and 36.2% respectively. On functional outcomes (EORTC QLQ-C30), only 32%-41% reported not being affected in the various facets of emotional function. Physical functions were affected in 19%-79%, role functions in 69%-75%; symptoms in 49%-80%; cognitive functions in 46%-56%; social functions in 63%-71% and financial aspects by 63%. On global QOL, 53% and 47% respectively reported high level disruption in overall physical health and overall QOL. CONCLUSION: Severe deterioration of QOL occurs as a result of diagnosis of inoperable cervical cancer and subsequent therapies. For this reason there is need to establish severe disease and end-of-life research and management services that would ensure better coping with cancer for patients and for home-based caregivers.

Part of a detailed analysis of 864 unmarried teenage mothers delivering in Pumwani Maternity Hospital and Kenyatta National Hospital is presented. Teenage pregnancy amounted for 42.3% of all deliveries of unmarried mothers. Most teenage patients were above 16 years of age, had a religious background of wide coverage, had low quality antenatal care and low education. 94.6% were found to be primigravidas. This dominance has also been found by other workers. PIP: A prospective cross-sectional descriptive study of unmarried mothers delivering in Pumwani Maternity Hospital and Kenyatta National Hospital, Nairobi, Kenya, from December 1986-April 1987, was conducted with a pretested open-ended questionnaire: the 864 teen mothers are described here. They ranged from 13.4-19 years, most were 17-19. 49.4% were Catholic and 45% Protestant. 88.5% attended prenatal clinics once; 51.5% attended 5 times, although only 13% went to hospital clinics for specialized care. For reasons for not going for prenatal care teens stated that they were too shy to undergo a clinical exam, afraid of parents' reaction, unaware of the pregnancy or of the existence of prenatal care, they had not menstruated, or were in school, in prison, or had long work hours. Most girls had primary education, and 97.9% had dropped out of school. 34% dropped out because of pregnancy, and 32% for lack of tuition fees. Reasons for dropping out of school were tabulated, encompassing a broad range of social problems such as war, death, divorce, alcoholism or illness of parents, no tuition or uniform funds, poor grades, and running away from school. In Africa, teen pregnancy is probably increasing because of decreasing age at menarche and relaxing of traditional values.

OBJECTIVE: To describe the pattern and prevalence of variations that occur in the supraclavicular part of the brachial plexus in a Kenyan population. STUDY DESIGN: Descriptive cross-sectional study. MATERIALS AND METHODS: Ninety-four brachial plexuses from forty-seven formalin fixed cadavers were displayed by gross dissection. RESULTS: The presence of at least one variation from the classical anatomy was observed in 73 (77.7%) of the 94 plexuses. The roots and trunks were involved in 32 (34%) of the plexuses . Pre- and postfixed roots were present in 23 (24.7%) and 3 (3.2%), respectively. The presence of four trunks, and trunks passing between the scalene medius and posterior were also noted. The long thoracic nerve was variant in 51 (54.3%) of the plexuses. Unusual relations of the phrenic nerve to scalene muscles and the subclavian vein were encountered. CONCLUSION: The presence of four trunks and an accessory phrenic nerve passing through the subclavian vein are probably described and reported for the first time. However, most of the variations of the BP among Kenyans are similar to those reported in the other populations.

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.

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

Separation of midgut membrane proteins from the tick, Ambylomma variegatum, using a nonionic detergent (Triton X-114), resulted in two protein fractions, namely DET (detergent) and AQ (aqueous). In immunoblotting analysis with polyclonal antibodies against these fractions, 4 proteins (Mr approximately 27,000, 67,000, 86,000 and 95,000,) and 2 proteins (M, approximately 54,000 and 67,000) were detected in the DET and AQ fractions, respectively. Three of the DET fraction proteins Mr approximately 27,000, 67,000 and 95,000 were glycosylated since they bound to the lectin, concanavalin A. In 2-dimensional gel electrophoresis, the AQ and DET fraction proteins were found to be acidic in nature. In a series of bioassay experiments, rabbits were first immunised with both DET and AQ fractions and then infested with ticks. The egg batch weights of these ticks were reduced by 50% compared to control ticks. Furthermore, there was a significant reduction in the hatchability of eggs laid by ticks fed on rabbits previously immunised with both DET (14%) and AQ (33%) fractions. Based on the egg hatchability, the reproductive capacity of ticks was reduced by 77 and 48% by DET and AQ fractions, respectively.

ABSTRACT
Introduction: Treatment of microbial infections has become complicated
due to increased resistance of microbes to the current drugs. The current
study investigates crude extracts and seven compounds from root and
stem bark of Cordia africana Lam. for antimicrobial and cytotoxic activity.
Methods: Extraction was done using 50% methanol in dichloromethane,
followed by chromatographic separation of compounds, whose structures
were established by interpretation of spectroscopic data. The in vitro
susceptibility of selected microbes to the crude extracts and pure compounds was determined. Cytotoxicity of 1, 6 and 7 was determined against
the drug sensitive, CCRF-CEM and resistant CEM/ADR-5000 cells, with
doxorubicin used as the standard. Results: The root bark extract of
C. africana yielded six known compounds: oleanolic acid (1), 3-β-lup-20(29)-
en-3-ol (2) stigmast-5,22-dien-3β-ol (3), 2-(2Z) -(3-hydroxy-3,7-dimethylocta2,6-dienyl)-1,4-benzenediol (4), 4-hydroxy-3-methoxy- benzaldehyde (5)
and 7-hydroxy-4′-methoxyisoflavone (6). The stem bark extract resulted to
1 and 2 alongside, ubiquinone-8 (7) and 1-octacosanol (8). Compound 1
showed moderate activity against Enterococcus faecium (IC50 of 14.44 µg/
mL), with vancomycin being inactive. Compounds 1, 6 and 7 showed cell
viability >50% against CEM/ADR5000 and CCRF-CEM cells at 10 µM and
therefore were considered inactive. Surprisingly, 1 was relatively more active compared to the standard, with cell viability of 57.93% against CEM/
ADR5000, versus 78.97% for doxorubicin. Conclusion: To the best of our
knowledge, this is the first report of the eight compounds from C. africana.
The cytotoxicity of 1, 6 and 7 are reported here for the first time. Traditional
use of the plant extract in management of various infections may be attributed to presence of 1, which displayed moderate antimicrobial activity.
Key words: Cordia africana, Ubiquinone-8, Oleanolic acid acid, 7-hydroxy4′-methoxyisoflavone, VRE.

The efficacy of bloodmeal digestion in teneral Glossina morsitans centralis fed on rabbits immunized with tsetse fly midgut extracts was progressively monitored over a period of 96 hours. Flies fed on immunized rabbits showed reduced rate of bloodmeal digestion as compared to the controls. Although there was insignificant difference in the rate of bloodmeal digestion upto 24 hours post-feeding in later stages of digestion there was quite a significant difference. Polyacrylamide gel electrophoretic patterns of bloodmeal drawn from the posterior sections of the midgut demonstrated that, bloodmeal is completely degraded in the midgut after 96 hours in the control flies, while substantial amount is still undigested in the experimental flies. However, not much difference in the rates of digestion was observed with bloodmeal drawn from the anterior section of the midgut. These results suggests that when flies are fed on rabbits immunized with tsetse fly midgut extract, there is an impairment on the efficiency of digestion. The anti-midgut antibodies could be interfering with either the induction or proteolytic activity of the midgut enzymes.

The human body louse, Pediculus humanus, showed eighteen midgut proteins ranging between 12 and 117 kDa, when analysed by SDS-PAGE electrophoresis. Seven of them (12 kDa, 17 kDa, 29 kDa, 35 kDa, 40 kDa, 55 kDa and 97 kDa) were major bands based on their intensity of staining. The immunization of rabbits with a midgut extract elicited the production of protective polyclonal antibodies. These antibodies reacted strongly with all major midgut proteins as well as with 63 kDa and 117 kDa proteins when tested by the Western blot technique. The analysis of the proteins revealed that the 12 kDa, 25 kDa, 29 kDa, 35 kDa, 45 kDa, 87 kDa and 97 kDa proteins are glycosylated and none of them contained a lipid moiety. By electroelution, the proteins of 35 kDa and 63 kDa were purified. On trypsinization, the proteins of 35 kDa and 63 kDa produced four major fragments (F1, F2, F3, and F4) when resolved on a 18% SDS-PAGE. The F1 fragment of the 35 kDa protein reacted with the polyclonal antibodies by the immunoblot technique.

SETTING: A rural district, Machakos, in Kenya, facing decreasing national resources for health and an increasing tuberculosis (TB) caseload fuelled by the human immunodeficiency virus (HIV). OBJECTIVE: To evaluate the impact on district TB programme performance of decentralising TB treatment by providing ambulatory care in the hospital and peripheral health units and in the community. METHODS: A comparative study of district TB programme performance before and after the decentralisation of TB services at the end of 1997. To facilitate ambulatory care, ethambutol replaced streptomycin in the new treatment regimen. FINDINGS: The number of patients registered in the control period (1996) was 1141, of whom almost 100% were admitted during the intensive phase of TB treatment, and in the intervention period (1998 and 1999), it was 3244, of whom only 153 (4.7%) required admission in the intensive phase. Of 3244 TB patients (all forms) registered in the intervention period, the number (%) choosing the different options for directly observed treatment (DOT) supervision were: hospital clinic 1618 (49.9%), peripheral health unit 904 (27.9%), community volunteer 569 (17.5%) and hospitalisation 153 (4.7%). The options were found to be acceptable to patients, their families and health staff. The treatment outcomes among new sputum smear-positive pulmonary TB patients were similar in the intervention and control cohorts, with treatment success rates of 88% vs. 85% and death rates of 4% vs. 6%, respectively. Treatment completion was significantly higher among new sputum smear-negative and extra-pulmonary TB patients in the intervention than in the control cohort (79% vs. 48%, respectively). CONCLUSION: The decentralisation of the intensive phase of TB treatment resulted in maintenance of good TB programme performance, while Machakos hospital closed its TB wards. A separate paper describes the cost-effectiveness of this approach. The National Tuberculosis Control Programme plans to adopt this approach as national policy.

NTRODUCTION: Family Health International developed a simple checklist to help family planning providers apply the new medical eligibility criteria (MEC) of the World Health Organization (WHO) for the use of the intrauterine device (IUD) contraceptive method. METHODS: One hundred thirty-five providers in four countries participated in focus groups to field test the checklist. Before participating in a discussion about the checklist, each provider was given a copy of the checklist, its instructions and hypothetical client scenarios. Providers used the checklist to answer questions about the client scenarios in order to determine if they understood the checklist and if they would correctly determine IUD eligibility for women in updated categories of eligibility on the basis of the checklist. RESULTS: Providers found the checklist easy to use and thought that it would enhance identification of eligible IUD users. Nevertheless, many providers relied on prior knowledge of IUD eligibility rather than the checklist recommendations. Providers only correctly determined eligibility for new categories of IUD use 69% of the time. CONCLUSIONS: The IUD checklist is a useful job tool for providers, but training and effective dissemination of the WHO MEC should precede its introduction to ensure that it is correctly used.

BACKGROUND: Pregnancy among adolescents is unplanned in many instances. Although some pregnant adolescents carry the pregnancy to term, abortion, in many instances unsafely induced, is a commonly sought solution in Kenya. OBJECTIVE: To determine adolescents' perceptions of induced abortion. DESIGN: A cross-sectional descriptive study carried out between July 1995 and June 1996. SETTING: An urban and a rural district in Kenya. PARTICIPANTS: Adolescents aged 10-19 years in schools in Nairobi and Kiambu districts, and a group of immediate post-abortion adolescent girls in some health facilities in Nairobi. MAIN OUTCOME MEASURES: The number of health programmes formulated and put into use, which are adolescent-friendly and providing information, education and communication on abortion issues. DATA COLLECTION: One thousand eight hundred and twenty adolescents were subjected to a self-administered questionnaire that collected demographic and health data as well as perceptions of induced abortion. Focus group discussions on perceptions of abortion were held with 12 groups of adolescents in schools and the information obtained recorded on paper and in a tape-recorder. RESULTS: One thousand nine hundred and fifty two adolescents, comprising of 1048 school girls (SG), 580 boys (SB), 192 post-abortion girls (PA) and 132 adolescents in the focus group discussions, formed the study sample. More than 90% were aware of induced abortion (IA). Knowledge of IA correlated positively with level of education (P < 0.01). Seventy one per cent of SG, 84% of PA and 40% of SB were aware of abortion-related complications, the most common being infections, death and infertility. Eighty three per cent of PA felt that complications were preventable by seeking care from a qualified doctor compared to one quarter each for the SB and SG. 56% PA, 69% SB and 72% SG felt that abortions were preventable. However, less than 40% proposed abstinence as a primary strategy. The most important source of information on abortion was the media followed by friends and teachers. CONCLUSION: Adolescents are aware of abortion and the related complications, but there is more variability in their knowledge and preventive measures.

OBJECTIVES. The purpose of this study was to identify health-care seeking and related behaviors relevant to controlling sexually transmitted diseases in Kenya. METHODS. A total of 380 patients with sexually transmitted diseases (n = 189 men and 191 women) at eight public clinics were questioned about their health-care seeking and sexual behaviors. RESULTS. Women waited longer than men to attend study clinics and were more likely to continue to have sex while symptomatic. A large proportion of patients had sought treatment previously in both the public and private sectors without relief of symptoms, resulting in delays in presenting to study clinics. For women, being married and giving a recent history of selling sex were both independently associated with continuing to have sex while symptomatic. CONCLUSIONS. Reducing the transmission of sexually transmitted diseases in Kenya will require improved access, particularly for women, to effective health services, preferably at the point of first contact with the health system. It is also critical to encourage people to reduce sexual activity while symptomatic, seek treatment promptly, and increase condom use.

The mammalian olfactory bulb (OB) has all the features of a whole mammalian brain but in a more reduced space: neuronal lamination, sensory inputs, afferences, or efferences to other centers of the central nervous system, or a contribution of new neural elements. Therefore, it is widely considered as "a brain inside the brain." Although this rostral region has the same origin and general layering as the other cerebral cortices, some distinctive features make it very profitable in experimentation in neurobiology: the sensory inputs are driven directly on its surface, the main output can be accessed anatomically, and new elements appear in it throughout adult life. These three morphological characteristics have been manipulated to analyze further the response of the whole OB. The present review offers a general outlook into the consequences of such experimentation in the anatomy, connectivity and neurochemistry of the OB after (a) sensory deprivation, mainly by naris occlusion; (b) olfactory deinnervation by means of olfactory epithelium damage, olfactory nerve interruption, or even olfactory tract disruption; (c) the removal of the principal neurons of the OB; and (d) management of the arrival of newborn interneurons from the rostral migratory stream. These experiments were performed using surgical or chemical methods, but also by means of the analysis of genetic models, some of whose olfactory components are missing, colorless or mismatching within the wild-type scenario of odor processing.

At the Kenyatta National Hospital (KNH) and other private hospitals in Nairobi urinary stone disease is not being correctly diagnosed. Over a 15 year period (1980-1995) only 56 patients have been confirmed to have urinary tract stones out of the expected number of 220 patients. The age range was 10-60 years. The peak age was 30-40 years. Pain and haematuria were the commonest presenting symptoms. Ultrasonography and plane abdominal radiology were the commonest methods of diagnosis. Open surgery and endoscopic stone removal were the commonest modes of management. Extracorporeal shortwave lithotripsy (ESWL) has recently been introduced into the Nairobi Hospital, but was not functional at the time of this study. Percutaneous nephrolithotomy (PCNL) is possible but has not been adequately used due to lack of correct equipment. Septicaemia and haemorrhage were the commonest complications of the open surgery.

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.

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. It is concluded from these studies that Kwashiorkor disease and diet-induced obesity appear to interfere with oxygen utilization at the level of state 3 mitochondrial respiration, which is markedly decreased when compared to the values for control animals.

The treatments were arranged in  randomized complete block design (RCBD) with four replications. In each season, the number of aphids in five randomly  selected plants per treatment was recordced in situ. Virus symptoms (i.ncidence) were scored and expressed as a percentage  to the total plant population per plot. Forty-five days after emergence, 10 plants each from guard rows and inner rows were  randomly selected and serologically assayed for Potato Virus Y (PVY) and Potato Leaf Roll Virus (PLRV) using DAS ELISA test. Results showd that three aphid species Aphis gossypii (Glover), Macrosiphum euphorbiae (Thomas) and Myzus persicae (Sulzer) colonized on the variety with A. gossypii being the most dominant while M. persicae was least.  Higher aphid population coincided with the short rains experienced in one of the seasons. Synthetic insecticides (Bifethrin  and dimethoate) were the most effective among the treatments in reducing aphid infestation while the neem extract and mineral oil (DC- Tron) had no significant (P<0.05) difference. However, mineral-oil treated plots recorded the lowest PVY  incidence while bifenthrin-Ireated plots had the lowest PLRV incidence. It is suggested that a combination of synthetic  insecticides and mineral oil could playa major role in reduction of the aphids and their associated vectors.

Department of Pharmacology and Toxicology, University of Nairobi, Kenya. The relative bioavailabilities of three carbamazepine tablet formulations available in the Kenyan market (Temporal(R), Taver(R) and Carbamazepine Lincoln) compared with the innovator formulation (Tegretol(R)) were evaluated in seven healthy African volunteers (5 males, two females; aged 22-36 years), according to a randomised fourway crossover study design, following oral administration of single 200 mg doses with a three week washout period. In vitro dissolution profiles of the tablets were also evaluated. Relative bioavailabilities ((F)rel) of Temporal(R), Taver(R) and Carbamazepine Linocoln were 101.2%, 82.2% and 71.6% respectively, compared with Tegretol(R). Percent drug content dissolved in vitro after I hour were 91.3%, 75.9% and 39.3% for Temporal(R), Taver(R) and Carbamazepine Lincoln, respectively. It was concluded that Temporal(R) was bioequivalent to Tegretol(R) while Taver(R) and Carbamazepin Lincoln were bioinequivalent to Tegretol(R). Administration of Taver(R) or Carbamazepine Lincoln might lead to poor control of epileptic seizures.

OBJECTIVE: To review literature on the coronary vascular factors related to the syndrome of sudden cardiac death. DATA SOURCE/SYNTHESIS: Major published articles and case reports on the nature of sudden cardiac death were searched electronically (Medline, Internet) and through hand scanning. Comparison of the different studies with regard to common themes was undertaken and consensus opinions highlighted. RESULTS: The aetiology of sudden cardiac death is diverse. Many conditions, hitherto considered benign, including coronary arterial anomalies and muscle bridges have been shown to cause sudden cardiac death. Coronary atherosclerosis, hypoplastic coronary vessels, coronary artery dissections are the commoner causes. The role of coronary arterial thrombi is controversial. The protective role of exercise is seriously questioned by the many reports of sudden cardiac death in long distance runners. CONCLUSION: Cases of sudden cardiac death are increasingly being reported. As a minimum, autopsy worksheets for cases of sudden death should include atherosclerosis, congenital coronary anomalies, tunneling of coronary vessels and hyposplastic vessels in addition to valvular and myocardial disorders.

Hydro-distilled volatile oils from the leaves of Ocimum gratissimum L. (Lamiaceae) from Meru district in Eastern Kenya were analysed by gas chromatography-mass spectrometry (GC-MS) and also evaluated for antimicrobial activity. The oil was dominated by monoterpens which accounted for 92.48%. This monoterpene fraction was characterized by a high percentage of eugenol (68.8%). The other major monoterpenes were methyl eugenol (13.21%), cis-ocimene (7.47%), trans-ocimene (0.94%), β-pinene (1.10%) and camphor (0.95%). The sesquiterpenes present in fairly good amounts were germacrene D (4.25%) and trans-caryophyllene (1.69%). The minor sesquiterpenes were α-farnesene (0.85%) and β-bisabolene (0.74%). The antimicrobial activities of the essential oils were evaluated against both Gram positive (Staphylococcus aureus, Bacillus spp.) and Gram negative (Escherichia coli, Pseudomonas aeruginosae, Salmonella typhi, Klebisiella pneumoniae, Proteus mirabilis) bacteria and a pathogenic fungus Candida albicans. The oil had pronounced antibacterial and antifungal activities on all the microbes.

Blood samples were collected at initial diagnosis and during follow-up. Mutation-specific nested PCR methods to analyse DHFR (Arg-59) and DHPS (Glu-540) mutations that are associated with SP drug resistance were applied. Parasite genotyping was performed to distinguish between re-infection and recrudescence. Eighty-six patients were recruited of which 66 were available for follow-up. Nine children were classified as early treatment failure, 13 cases were classified as late clinical failure, 32 as late parasitological failure, and only 12 children had an adequate clinical and parasitological response. DHFR and DHPS mutations conferring SP resistance were abundant in the Plasmodium population. Blood samples obtained 7 days after treatment were used to predict retrospectively the outcome of SP treatment. QT-NASBA was able to give a correct prediction of treatment outcome in 85.7% of the cases. Positive predictive value (PPV) of QT-NASBA case was 95% (95% confidence interval = 88.3-100) and negative predictive value (NPV) was 63% (95% CI = 39.5-86.5). In contrast, microscopy correctly predicted outcome in only 37.5% of the cases. PPV of microscopy was 100% (95% CI = 73.9-100) and the NPV was 25.5% (95% CI = 13.0-38.0). The analysis of a day 7 blood sample with QT-NASBA allows for the prediction of late clinical or parasitological treatment failure in the majority of the cases analysed in the present study.

"Omari MA, Malonza IM, Bwayo JJ, Mutere AN, Murage EM, Mwatha AK, Ndinya-Achola J O;Pattern of bacterial infections and antimicrobial susceptibility at Kenyatta National Hospital, Nairobi Kenya. East Afr Med J. 1997 Mar;74(3):134-7.". In: East Afr Med J. 1997 Mar;74(3):134-7. IBIMA Publishing; 1977. Abstract
To monitor clinically significant isolates and their antimicrobial susceptibilities, all specimens sent to microbiology laboratory of the Kenyatta National Hospital were cultured on appropriate media. The susceptibility of the isolates was performed on Muller Hinton or diagnostic sensitivity test (DST) agar using comparative discs diffusion technique. The results were then entered into Microbe Base 2 computer programme. A total of 7416 clinically significant isolates were collected from 1991 to 1995. The most commonly isolated organisms were E.coli, Klebsiella and Staphylococcus aureus. Most of these hospital acquired infections had multiple resistance to conventional antimicrobials, namely, penicillin, tetracyclines, gentamicin, trimethoprim/sulphamethoxazole and ampicillin. The resistance pattern was high among both gram negative and positive bacteria isolates. Beta-lactamase production amongst them were 51%, 69.3%, 79.6% respectively. Prevalence of methicillin resistant Staphylococcus aureus was 39.8%. Addition of clavulanic acid to amoxycillin increased Staphylococcus aureus susceptibility three fold. The emergence of multiple drug resistance calls for a continuous monitoring and reviewing of antibiotic policy in the hospital and the country at large.

This study evaluated a direct multiplex PCR to detect food contamination with enterotoxigenic Bacillus cereus (B. cereus) in comparison with culture and multiplex gene detection using colonies. Detection of B. cereus enterotoxin genes was done on artificially contaminated and ready-to- eat market foods including cooked rice, pasteurized milk and cheese. Of the 108 food samples analysed, 51(47.2 % were found to be contaminated with enterotoxigenic B. cereus by culture and enterotoxin detection by multiplex PCR, but only 14(12.9%) of them were found to be contaminated with enterotoxigenic B. cereus by direct multiplex PCR. B. cereus enterotoxin genes were detected only in artificially contaminated and ready-to-eat market foods with bacterial counts of equal or more than 4000 (4x103 ) cfu/ml for both pasteurized milk and cheese and equal or more than 40,000 cfu/g for cooked rice. Since high contamination of food with B. cereus (107 cfu/g) has been associated with food poisoning, this technique can be used to identify foods suspected to cause food poisoning without culture and identification of B. cereus Detection of any of the enterotoxin genes will indicate contamination of foods with enterotoxigenic B. cereus group.

            Fluoride determinations were made with a fluoride ion selective electrode on 60 river water samples collected at readily accessible sites in Central and Nairobi provinces of Kenya. The highest fluoride concentration was 0.85 ppm in Laikipia District and the lowest was 0.08 ppm in Murang'a District. By region and district, the mean fluoride concentration ranged from 0.12 ppm for rivers in Laikipia to 0.24 ppm for rivers in Nairobi, with 0.32 ppm in the Upper Basin of the Athi River. The results indicate that the rivers are relatively low in fluoride and are therefore safe in this respect for domestic and industrial use.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

In addition the research went ahead to establish the avenues available to mobile phone manufacturers and users in order to enhance safe mobile disposal through a survey.  The research revealed that there was the need for the mobile manufacturers to manufacture handsets from recyclable materials. The manufacturers should also avail information on handset disposal at the point of sale and do a follow-up using the available media. The mobile services providers can also play an important role on mobile phone disposal by availing the information on the face of the scratch cards. In addition they can notify the subscribers on the available disposal channels through text messages. The government through the designated agencies such as the Communications Commission of Kenya (CCK) and National Environmental Management Authority (NEMA) needs to be more assertive in mobile phone disposal measures.

Department of Pharmacology and Toxicology, University of Nairobi, Kenya. The relative bioavailabilities of three carbamazepine tablet formulations available in the Kenyan market (Temporal(R), Taver(R) and Carbamazepine Lincoln) compared with the innovator formulation (Tegretol(R)) were evaluated in seven healthy African volunteers (5 males, two females; aged 22-36 years), according to a randomised fourway crossover study design, following oral administration of single 200 mg doses with a three week washout period. In vitro dissolution profiles of the tablets were also evaluated. Relative bioavailabilities ((F)rel) of Temporal(R), Taver(R) and Carbamazepine Linocoln were 101.2%, 82.2% and 71.6% respectively, compared with Tegretol(R). Percent drug content dissolved in vitro after I hour were 91.3%, 75.9% and 39.3% for Temporal(R), Taver(R) and Carbamazepine Lincoln, respectively. It was concluded that Temporal(R) was bioequivalent to Tegretol(R) while Taver(R) and Carbamazepin Lincoln were bioinequivalent to Tegretol(R). Administration of Taver(R) or Carbamazepine Lincoln might lead to poor control of epileptic seizures.

"Omondi D, Ogol C, Otieno S, Macharia I.Parental awareness of hearing impairment in their school-going children and healthcare seeking behaviour in Kisumu district, Kenya.Int J Pediatr Otorhinolaryngol. 2007 Mar;71(3):415-23. Epub 2006 Dec 18.". In: Int J Pediatr Otorhinolaryngol. 2007 Mar;71(3):415-23. Epub 2006 Dec 18. University of Nairobi Case, in the proceedings of the IST-Africa 2008 Conference; Windhoek, Namibia; 2006. Abstract

BACKGROUND: Hearing-impaired children who are identified early and appropriately managed have improved outcomes in speech, language, cognitive and social development. Enhanced parental awareness of their child's hearing disability, behavioral, developmental and psychosocial limitations is essential to sustaining timely detection and appropriate intervention. Additionally, availability of services for diagnosis, treatment and habilitation would improve the demand for pedaudiological care in this community. OBJECTIVE: To describe level of parental awareness of childhood HI and the pattern of access to and utilization of ambulatory care services. SUBJECTS: Thirty-three parents of lower primary school-going children who failed audiometric screening from sampled schools in Kisumu district, western Kenya. MAIN OUTCOME MEASURES: First person to detect HI, age of child at first suspicion of HI, source of ambulatory health care and use of the health care facilities. RESULTS: The prevalence of HI was 2.48%. Most parents/guardians (69.7%) were aware of their child's hearing impairment. Of these, 63.6% were first to detect HI in the pupils, while 30.3% were detected by screen. Most children (57.2%) were first recognized with (HI) after age 2 years. The mean age at identification was 5.5 years. The median travel distance to the preferred health care facility was 2 km (IQR 1-2.5). Parents seldom sought or lacked help for their hearing-impaired children. Of 27.3% who asked for hearing assessment, 9.1% received some counsel on HI and 12.1% received medication, one (3%) was referred for audiological assessment and none used a hearing aid. Use of health facilities for maternal care was (65.7%) and immunization (62.9%). CONCLUSIONS: Despite adequate parental awareness of chronic childhood disability, health facilities were underutilized. This indicates the need to further stimulate and maintain a desirable level of uptake of services for diagnosis, treatment and habilitation of childhood HI, while sustaining delivery of effective and acceptable high quality paediatric care.

OBJECTIVE: To determine the range of ablative surgery and rehabilitative procedures performed on maxillofacial structures. DESIGN: A retrospective descriptive study. SETTING: University of Nairobi Dental Teaching Hospital. SUBJECTS: Patients operated on at the institutions theatre, and followed up at the University of Nairobi Dental Teaching Hospital Oral Surgery Outpatient Clinic during the period February 1996, August 1998. RESULTS: Forty four patients underwent ablative surgery during the study period. Complete records were available for 38 patients, 27 females and 11 males aged 10 to 79 years (mean 32.6 years). Surgical procedures performed included: partial mandibulectomy, marginal mandibular resection, subtotal maxillectomy, sequestrectomy and enucleation. Six (15.8%) patients who underwent mandibular resection had rigid bone plating. Five (13.2%) patients who had maxillary involvement were given surgical obturators post-operatively with one receiving a complete denture after full recovery. A total of 22 (57.9%) patients who would have reaped benefits from prostheses therapy received none. Individual patient follow-up periods ranged from seven days for two patients who had cyst enucleation to two years for three cases with ameloblastoma, and two cases with squamous cell carcinoma. CONCLUSION: It is concluded that prosthetic rehabilitation of patients undergoing extensive surgery at the University of Nairobi Dental Teaching Hospital is largely inadequate.
