A model for the establishment of a four-dimensional regional geodetic reference datum is presented. Starting from the three-dimensional integrated geodetic network model, formulations for the establishment of a four-dimensional regional datum are developed. Astronomic latitudes, astronomic longitudes, gravity values, gravity potential differences, gravity differences, and GPS-vectors are considered as observables. The estimated parameters defining the datura are point coordinates, deflections of the vertical and geoidai undulations, and velocities and accelerations on the positional coordinates. The network datum is considered observed over several epochs with parameters estimated from previous epochs being introduced into later epochs as stochastic prior information parameters.

Ectoparasitism is an important factor associated with poor production of village indigenous chickens. A cross-sectional study was carried out to determine the prevalence of ectoparasites in free ranging indigenous chicken from two different agro-ecological zones: Lower highland 1 (LH1) in Embu District and Lower midland 5 (LM5) in Mbeere District, Kenya. A total of 144 chickens of matched age (chicks, growers and adults) and sex groups were examined for the presence of ectoparasites. Of these, 138 (95.8%) had one or more types of ectoparasites, namely; lice, mites, fleas and soft ticks. One thirty one birds had lice, 107 mites, 42 sticktight fleas and 8 had soft ticks. Of the 138 infested birds, 25 had single while 113 had mixed infestations. Lice were the most prevalent parasites. The study documents Epidermoptes species, Laminosioptes cysticola and Megninia species for the first time in Africa as well as Lipeurus caponis and Goniodes gigas in Kenya. All adult birds were infected with ectoparasites followed by 97.7% grower and 89.6% chicks. Both male and female birds had same prevalence (95.8%) of ectoparasites. Lower midland 5 had a slightly higher prevalence of ectoparasites (98.6%) compared to LH1 (93.1%) though not statistically significant. Parasite intensity was significantly different among age groups of chicken and between agro-ecological zones (p<0.05), but not between sexes of birds (p>0.05). Because of the high prevalence of ectoparasites revealed by this study, it is imperative that integrated control strategies need to be put in place to improve chicken productivity and enhance smallholder livelihood in these areas.

Time course investigation of infection with a low virulent Pasteurella multocida strain in normal and immune-suppressed 12 week-old free range chickens. Av.". In: Avian pathology. Avian pathology; 2011. Abstract
Twelve-week-old indigenous chickens, either immune-suppressed using dexamethasone (IS) or non-immunesuppressed (NIS), were challenged with a low virulent strain, Pasteurella multocida strain NCTC 10322, and developed clinical signs and pathological lesions typical of chronic fowl cholera. NIS birds demonstrated much more severe signs of fowl cholera than IS birds. With few exceptions, signs recorded in IS and NIS birds were of the same types, but significantly milder in the IS birds, indicating that immune suppression does not change the course of infection but rather the severity of signs in fowl cholera. P. multocida signals by fluorescent in situ hybridization (FISH) were observed between 1 h and 14 days in the lungs, trachea, air sacs, liver, spleen, bursa of Fabricius and caecal tonsils, while signals from other organs mostly were observed after 24 h. More organs had FISH signals in NIS birds than in IS birds and at higher frequency per organ. Many organs were positive by FISH even 14 days post infection, and it is suggested that these organs may be likely places for long-term carriage of P. multocida following infection. The present study has demonstrated the spread of P. multocida in different tissues in chickens and distribution of lesions associated with chronic fowl cholera, and pointed to a decrease of pathology in IS birds. Since dexamethasone mostly affects heterophils, the study suggests that these cells play a role in the development of lesions associated with chronic fowl cholera in chickens.

Partnerships between communities and academic ecologists can address this capacity deficit, modernize the evidence base for such approaches and enable future scale up. Community-based IVM programmes were initiated in two contrasting settings. On Rusinga Island, Western Kenya, community outreach to a marginalized rural community was achieved by University of Nairobi through a community-based organization. In Dar es Salaam, Tanzania, Ilala Municipality established an IVM programme at grassroots level, which was subsequently upgraded and expanded into a pilot scale Urban Malaria Control Programme with support from national academic institutes. Both programmes now access relevant expertise, funding and policy makers while the academic partners benefit from direct experience of community-based implementation and operational research opportunities. The communities now access up-to-date malaria-related knowledge and skills for translation into local action. Similarly, the academic partners have acquired better understanding of community needs and how to address them. Until sufficient evidence is provided, community-based IVM remains an operational research activity. Researchers can never directly support every community in Africa so community based IVM strategies and tactics will need to be incorporated into undergraduate teaching programmes to generate sufficient numbers of practitioners for national scale programmes. Academic ecologists at African institutions are uniquely positioned to enable the application of practical environmental and entomological skills for malaria control by communities at grassroots level and should be supported to fulfil this neglected role.

Ectoparasitism is an important factor associated with poor production of village indigenous chickens. A cross-sectional study was carried out to determine the prevalence of ectoparasites in free ranging indigenous chicken from two different agro-ecological zones: Lower highland 1 (LH1) in Embu District and Lower midland 5 (LM5) in Mbeere District, Kenya. A total of 144 chickens of matched age (chicks, growers and adults) and sex groups were examined for the presence of ectoparasites. Of these, 138 (95.8%) had one or more types of ectoparasites, namely; lice, mites, fleas and soft ticks. One thirty one birds had lice, 107 mites, 42 sticktight fleas and 8 had soft ticks. Of the 138 infested birds, 25 had single while 113 had mixed infestations. Lice were the most prevalent parasites. The study documents Epidermoptes species, Laminosioptes cysticola and Megninia species for the first time in Africa as well as Lipeurus caponis and Goniodes gigas in Kenya. All adult birds were infected with ectoparasites followed by 97.7% grower and 89.6% chicks. Both male and female birds had same prevalence (95.8%) of ectoparasites. Lower midland 5 had a slightly higher prevalence of ectoparasites (98.6%) compared to LH1 (93.1%) though not statistically significant. Parasite intensity was significantly different among age groups of chicken and between agro-ecological zones (p<0.05), but not between sexes of birds (p>0.05). Because of the high prevalence of ectoparasites revealed by this study, it is imperative that integrated control strategies need to be put in place to improve chicken productivity and enhance smallholder livelihood in these areas.

Aim of the study: This study was conducted to document herbal medicines used in the treatment of Malaria as well as the existing knowledge,attitudes and practices related to malaria recognition, control and treatment in South Coast, Kenya. Methods: Data was collected using semistructured questionnaires and interviews. A focused group discussion held with the community members, one in each of the study villages supplemented the interview and questionnaire survey. Results: The respondents were found to have a good understanding of malaria and could distinguish it from other fever types. They were also aware that malaria was spread by mosquitoes. Malaria prevalence was high, and affected individuals an average of four times a year. Community members avoided. Mosquito bites by using mosquitonets, clearing bushes around their homesteads and burning plant parts. To generate smoke. They prevented and treated malaria by taking decoctions or concoctions of traditional herbal remedies. Forty plant species in thirty-five genera distributed in twenty-four families were used as antimalarials in the study area. Five plant species, namely; Heeria insignis Del. (Anacardiaceae), Rottboelia exaltata L.F (Gramineae), Pentanisia ouranogyne S. Moore (Rubiaceae), Agathisanthenum globosum (A. Rich) Hiern (Rubiaceae), and Grewia trichocarpa Hochst ex A. Rich (Tiliaceae) are documented for the first time in South Coast, Kenya, for the treatment of malaria. Conclusions: The plants documented in the current study are a potential source for new bioactive compounds of therapeutic value in malaria treatment. The results provide data for further pharmacological and toxicological studies and development of commercial antimalarial phytotherapy products.

Physical and chemical properties of soil surface crusts formed on overgrazed bare ground, in Mukogodo catchment in Kenya were investigated. These were compared with those of underlying soils and of adjacent grass and bush covered topsoils. Crusting effects on infiltration, hydraulic conductivity and water content were also investigated. The crusts were moderately strong to strong with a thickness of 1-5 mm. Crusts had higher amounts of sand, silt and clay than the underlying layer, while their total N was lower and organic C content higher than the underlying layer. On average, the contents of Ca, Mg and Na were higher in the crusts than in the underlying layers. Similarly, soil pH, EC and ESP were higher in the crusts than in the underlying layer. Cation exchange capacity and K were slightly higher in the underlying layer than in the crusts. Infiltration, hydraulic conductivity and soil water content in both the rainy and dry seasons in bare ground were significantly lower than those of the bush and grass covered topsoils. Bare ground surface soil bulk density was higher compared to vegetated topsoils and subsurface layers

Influence of soil type and landuse on soil water retention and availability in the semi-arid Sirima and Mukogodo catchments in Laikipia District were investigated. Representative soils, six in Sirima and four in Mukogodo, surveyed at a detailed level, were assessed using samples taken from 0-10, 20-30 and 40-5 cm depths of bush, grass, bare ground and cultivated sites. Sirima soils retained more water than Mukogodo soils due to differences in clay type and textural composition. All Sirima soil layers were clay while Mukogodo topsoils were sandy loam and subsurface layers sandy clay loam. Mukogodo soils were more compact and had significantly lower carbon content than Sirima soils at all depths. For each area, only the surface layer had significant difference (p<0.05) in water retention among landuses, with bare ground retaining the most especially at higher pressures. However, no distinction in water availability could be made among soil types in each area. Unlike the increase in clay content with depth, bulk density and carbon content were not significant in influencing plant water availability

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.

A semi-detailed soil survey at 1:20,000 scale was carried out in an area of approximately 8000 ha on the northwestern slopes of Mt. Kenya. The soils have developed mainly from intermediate igneous rocks (trachytes) and occur in four main physiographic units: mountains, footslopes, footridges and valleys. The soils of the mountains and valleys are mainly cambisols and leptosols; those of the footslopes are shallow andosols and cambisols; and those of the footridges are andosols; alisols and luvisols. The soils show diverse physical and chemical characteristics. They range from well to poorly drained, shallow to deep, dark reddish brown (10YR 4/6) to brownish black (10YR 3/2), silty loam to clay. Topsoil organic carbon lies between 1.6 and 12.5 percent, base saturation is between 57 and 93 percent, and the cation exchange capacity (CEC) is between 15.5 and 23.5 cmol kg-1. Soil pH in both topsoils and subsoils varies from slightly acid to neutral (5.3 to 7.2). The moisture regime is udic in the upper part of the mountain and ustic in the lower part (i.e. mean annual rainfall of 700 to 900mm), while the temperature regime is isomeric on the upper slopes and isothermic on the lower slopes (i.e. mean annual temperature of 8 to 150C and 15 to 220C, respectively). The soils are moderately fertile, with a reasonable moisture storage capacity

Between June and December 1992 forty AIDS patients as defined by the CDC criteria, admitted to the medical wards of the Kenyatta National Hospital, were studied to determine the prevalence and pattern of peripheral neuropathy. Their mean age was 33 +/- 3 years with a range of 16 to 55 years. Clinical and laboratory assessment were carried out both to confirm peripheral neuropathy and exclude other causes of peripheral neuropathy apart from AIDS. All the patients had nerve conduction and electromyographic studies done. Eighteen patients were asymptomatic while fourteen had both signs and symptoms. The commonest symptom was painful paresthesiae of the limbs (35%) while the commonest sign was loss of vibration sense (60%). When symptoms, signs, and electrophysiological studies were combined, all the patients fitted the definition of peripheral neuropathy. The commonest type of peripheral neuropathy was distal symmetrical peripheral neuropathy (DSPN) (37.5%). PIP: In Kenya, physicians evaluated 40 AIDS patients admitted to Kenyatta National Hospital during June-December 1992 to determine the prevalence and types of peripheral neuropathy in AIDS patients. 75% were 21-40 years old. 18 (45%) of the 40 AIDS patients had symptoms of peripheral neuropathy. Symptoms included increased sensitivity to stimulation (43%), hyperpathia (15%), and muscle or limb weakness (13%). 26 AIDS patients had signs of peripheral neuropathy, especially impaired sense of vibration (60%). 14 of these patients had both signs and symptoms. Electromyographic and nerve conduction velocity revealed peripheral neuropathy in 16 (40%) AIDS patients. The types of peripheral neuropathy included distal symmetrical peripheral neuropathy (37.5%), polyneuropathy, and mononeuritis multiplex.

Between June and December 1992 forty AIDS patients as defined by the CDC criteria, admitted to the medical wards of the Kenyatta National Hospital, were studied to determine the prevalence and pattern of peripheral neuropathy. Their mean age was 33 +/- 3 years with a range of 16 to 55 years. Clinical and laboratory assessment were carried out both to confirm peripheral neuropathy and exclude other causes of peripheral neuropathy apart from AIDS. All the patients had nerve conduction and electromyographic studies done. Eighteen patients were asymptomatic while fourteen had both signs and symptoms. The commonest symptom was painful paresthesiae of the limbs (35%) while the commonest sign was loss of vibration sense (60%). When symptoms, signs, and electrophysiological studies were combined, all the patients fitted the definition of peripheral neuropathy. The commonest type of peripheral neuropathy was distal symmetrical peripheral neuropathy (DSPN) (37.5%). PIP: In Kenya, physicians evaluated 40 AIDS patients admitted to Kenyatta National Hospital during June-December 1992 to determine the prevalence and types of peripheral neuropathy in AIDS patients. 75% were 21-40 years old. 18 (45%) of the 40 AIDS patients had symptoms of peripheral neuropathy. Symptoms included increased sensitivity to stimulation (43%), hyperpathia (15%), and muscle or limb weakness (13%). 26 AIDS patients had signs of peripheral neuropathy, especially impaired sense of vibration (60%). 14 of these patients had both signs and symptoms. Electromyographic and nerve conduction velocity revealed peripheral neuropathy in 16 (40%) AIDS patients. The types of peripheral neuropathy included distal symmetrical peripheral neuropathy (37.5%), polyneuropathy, and mononeuritis multiplex. When the symptoms, signs, and electroneurophysiological test findings were considered, all 40 AIDS patients had evidence of peripheral neuropathy.

{ To test the hypothesis that micronutrient supplementation decreases genital HIV-1 shedding, a double-blind, randomized, placebo-controlled trial of 6 weeks of multivitamin plus selenium supplementation vs. placebo was conducted among 400 HIV-1-seropositive, nonpregnant, antiretroviral-naive women in Mombasa, Kenya. Primary outcome measures included cervical and vaginal shedding of HIV-1-infected cells and RNA. Secondary outcomes included plasma viral load and CD4 count. Surprisingly, the odds of detection of vaginal HIV-1-infected cells were 2.5-fold higher (P = 0.001) and the quantity of HIV-1 RNA in vaginal secretions was 0.37 log10 copies/swab higher (P = 0.004) among women who received micronutrients in comparison to placebo, even after adjustment for potential confounders including baseline HIV-1 shedding and CD4 count. The increase in vaginal HIV-1 shedding was greatest among women who had normal baseline selenium levels. Micronutrient supplementation resulted in higher CD4 (+23 cells/microL

Abstracta_comparison_of_genital_hiv-1_shedding_and_sexual_risk_behaviour_among_kenyan_women_based_on_eligibility_for_initiation_of_haart_according_to_who_guide.pdf

BACKGROUND:
Guidelines for initiating antiretrovirals are based on markers of advanced disease and are not directly linked to markers of HIV-1 transmission such as viral shedding.
METHODS:
We evaluated genital HIV-1 shedding and risk behavior among 650 antiretroviral-naïve women stratified by WHO criteria for initiating antiretrovirals based on CD4 count and symptoms.
RESULTS:
Genital HIV-1 concentrations increased in stepwise fashion with declining CD4 counts and the presence of symptoms. Compared with the reference group (asymptomatic with CD4 >350 cells/microL), those with advanced immunosuppression (CD4 <200 cells/microL) had significantly higher cervical HIV-1 RNA concentrations (2.4 log10 copies/swab vs. 3.8 log10 copies/swab, P < 0.001). However, women with CD4 counts <200 cells/microL were also less likely than the reference group to report intercourse during the past week (58% vs. 26%, P < 0.001).
CONCLUSIONS:
Antiretroviral guidelines focusing on individuals with the most advanced immunosuppression will target those with the highest genital HIV-1 concentrations. However, individuals with less advanced immunosuppression also have high levels of genital HIV-1 and may be more sexually active. The effect of increased antiretroviral availability on the spread of HIV-1 might be enhanced by extending treatment, in addition to other risk reduction services, to those with less advanced disease

{ BACKGROUND: Low serum selenium has been associated with lower CD4 counts and greater mortality among HIV-1-seropositive individuals, but most studies have not controlled for serum albumin and the presence of an acute phase response. METHODS: A cross-sectional study was conducted to evaluate relationships between serum selenium concentrations and CD4 count, plasma viral load, serum albumin, and acute phase response markers among 400 HIV-1-seropositive women. RESULTS: In univariate analyses, lower CD4 count, higher plasma viral load, lower albumin, and the presence of an acute phase response were each significantly associated with lower serum selenium concentrations. In multivariate analyses including all four of these covariates, only albumin remained significantly associated with serum selenium. For each 0.1 g/dl increase in serum albumin, serum selenium increased by 0.8 microg/l (p < 0.001). Women with an acute phase response also had lower serum selenium (by 5.6 microg/l

BACKGROUND: Changes in sexual risk behaviour may occur following HIV-1 infection. OBJECTIVE: To test the hypothesis that HIV-1 seroconversion and disease progression are associated with changes in risk behaviours, using data from a cohort of Kenyan female sex workers (FSWs). METHODS: HIV-1-seronegative FSWs were enrolled in a prospective cohort study of risk factors for HIV-1 acquisition. At monthly visits, standardized interviews were conducted to assess sexual risk behaviour and HIV-1 serologic testing was performed. Seroconverters were invited to continue with follow-up. Between 1993 and 2004 (when antiretroviral therapy was introduced in the cohort), 265 women seroconverted for HIV-1 (incidence 7.7/100 person-years) and were included in this analysis. RESULTS: Unprotected intercourse was reported at 546/2037 (27%) pre-seroconversion visits versus 557/3732 (15%) post-seroconversion visits (P < 0.001). These findings remained significant after adjustment for potential confounding factors [adjusted odds ratio (AOR) 0.69; 95% confidence interval (CI), 0.55-0.86]. Compared with HIV-1-seronegative women, there was a progressive stepwise decrease in unprotected intercourse among HIV-1-seropositive women with CD4 cell counts > or = 500 (AOR, 0.93; 95% CI, 0.62-1.39), 200-499 (AOR, 0.58; 95% CI, 0.41-0.82) and < 200 cells/microl (AOR, 0.45; 95% CI, 0.25-0.82). Decreases in unprotected intercourse reflected increases in both abstinence and 100% condom use. Women also reported fewer partners and fewer episodes of intercourse after HIV-1 seroconversion. CONCLUSIONS: HIV-1 seroconversion and disease progression were associated with decreases in sexual risk behaviour among Kenyan FSWs.

We conducted a prospective study among women in Mombasa, Kenya, to determine whether Trichomonas vaginalis infection was associated with an increased risk of human immunodeficiency virus type 1 (HIV-1) infection. At monthly follow-up visits, laboratory screening for HIV-1 and genital tract infections was conducted. Among 1335 HIV-1-seronegative women monitored for a median of 566 days, there were 806 incident T. vaginalis infections (23.6/100 person-years), and 265 women seroconverted to HIV-1 (7.7/100 person-years). Trichomoniasis was associated with a 1.52-fold (95% confidence interval, 1.04-2.24-fold) increased risk of HIV-1 acquisition after adjustment for potential confounding factors. Treatment and prevention of T. vaginalis infection could reduce HIV-1 risk in women.

BACKGROUND: Sexually transmitted diseases (STDs) enhance human immunodeficiency virus (HIV)-1 susceptibility, but few studies have examined the reciprocal effect of HIV-1 on STD acquisition. METHODS: Data from a prospective cohort study conducted among female sex workers in Mombasa, Kenya between 1993 and 2003 were used to determine the effect of HIV-1 infection on STD susceptibility. The cohort included 1215 HIV-1-seronegative women who underwent monthly HIV-1 and STD screening, of whom 238 experienced seroconversion to HIV-1 during follow-up. Andersen-Gill proportional-hazards models were used to compare the incidence rates for genital-tract infections (syphilis, genital ulcer disease [GUD], Neisseria gonorrhoeae infection, Chlamydia trachomatis infection, Trichomonas vaginalis infection, vulvovaginal candidiasis, and bacterial vaginosis) in HIV-1-seropositive versus HIV-1-seronegative women, after controlling for sexual behavior and other potential confounding factors. RESULTS: HIV-1 infection was associated with a significantly higher incidence of GUD (hazard ratio [HR], 2.8; 95% confidence interval [CI], 2.0-3.9), gonorrhea (HR, 1.6; 95% CI, 1.1-2.2), and vulvovaginal candidiasis (HR, 1.5; 95% CI, 1.3-1.8). The risks of GUD and vulvovaginal candidiasis increased with progressive levels of immunosuppression. CONCLUSIONS: The increased incidence of genital-tract infections among HIV-1-seropositive women could promote the spread of both HIV-1 and other STDs, particularly in areas where these conditions are highly prevalent.

Introduction. Male circumcision is being promoted for HIV prevention in high-risk heterosexual populations. However, there is a concern that circumcision may impair sexual function. Aim. To assess adult male circumcision's effect on men's sexual function and pleasure. Methods. Participants in a controlled trial of circumcision to reduce HIV incidence in Kisumu, Kenya were uncircumcised, HIV negative, sexually active men, aged 18-24 years, with a hemoglobin >/=9.0 mmol/L. Exclusion criteria included foreskin covering less than half the glans, a condition that might unduly increase surgical risks, or a medical indication for circumcision. Participants were randomized 1:1 to either immediate circumcision or delayed circumcision after 2 years (control group). Detailed evaluations occurred at 1, 3, 6, 12, 18, and 24 months. Main Outcome Measures. (i) Sexual function between circumcised and uncircumcised men; and (ii) sexual satisfaction and pleasure over time following circumcision. Results. Between February 2002 and September 2005, 2,784 participants were randomized, including the 100 excluded from this analysis because they crossed over, were not circumcised within 30 days of randomization, did not complete baseline interviews, or were outside the age range. For the circumcision and control groups, respectively, rates of any reported sexual dysfunction decreased from 23.6% and 25.9% at baseline to 6.2% and 5.8% at month 24. Changes over time were not associated with circumcision status. Compared to before they were circumcised, 64.0% of circumcised men reported their penis was "much more sensitive," and 54.5% rated their ease of reaching orgasm as "much more" at month 24. Conclusions. Adult male circumcision was not associated with sexual dysfunction. Circumcised men reported increased penile sensitivity and enhanced ease of reaching orgasm. These data indicate that integration of male circumcision into programs to reduce HIV risk is unlikely to adversely effect male sexual function.

BACKGROUND: There is limited information on the natural history of human immunodeficiency virus type 1 (HIV-1) infection in Africa, especially from individuals with well-defined dates of infection. We used data from a prospective cohort study of female sex workers in Mombasa, Kenya, who were followed up monthly from before the date of HIV-1 infection. METHODS: Antiretroviral-naive women who had a well-defined date of HIV-1 infection were included in this analysis. The effects of set point plasma viral load (measured 4-24 months after infection), early CD4+ cell count, and symptoms of acute HIV-1 infection on mortality were assessed using Cox proportional hazards analysis. RESULTS: Among 218 women, the median duration of follow-up after HIV-1 infection was 4.6 years. Forty women died, and at 8.7 years (the time of the last death), the cumulative survival rate was 51% by Kaplan-Meier analysis. Higher set point viral load, lower early CD4+ cell count, and more-symptomatic acute HIV-1 illness each predicted death. In multivariate analysis, set point viral load (hazard ratio [HR], 2.28 per 1 log10 copies/mL increase; P=.001) and acute HIV-1 illness (HR, 1.14 per each additional symptom; P=.05) were independently associated with higher mortality. CONCLUSION: Among this group of African women, the survival rate was similar to that for HIV-1-infected individuals in industrialized nations before the introduction of combination antiretroviral therapy. Higher set point viral load and more-severe acute HIV-1 illness predicted faster progression to death. Early identification of individuals at risk for rapid disease progression may allow closer clinical monitoring, including timely initiation of antiretroviral treatment.

BACKGROUND: Bacterial vaginosis (BV) is common and has been associated with increased HIV-1 susceptibility. The objective of this study was to identify risk factors for BV in African women at high risk for acquiring HIV-1. METHODS: We conducted a prospective study among 151 HIV-1-seronegative Kenyan female sex workers. Nonpregnant women were eligible if they did not have symptoms of abnormal vaginal itching or discharge at the time of enrollment. At monthly follow-up, a vaginal examination and laboratory testing for genital tract infections were performed. Multivariate Andersen-Gill proportional hazards analysis was used to identify correlates of BV. RESULTS: Participants completed a median of 378 (interquartile range 350-412) days of follow-up. Compared with women reporting no vaginal washing, those who reported vaginal washing 1 to 14 [adjusted hazard ratio (aHR) 1.29, 95% confidence interval (CI) 0.88-1.89], 15 to 28 (aHR 1.60, 95% CI 0.98-2.61), and >28 times/wk (aHR 2.39, 95% CI 1.35-4.23) were at increased risk of BV. Higher BV incidence was also associated with the use of cloth for intravaginal cleansing (aHR 1.48, 95% CI 1.06-2.08) and with recent unprotected intercourse (aHR 1.75, 95% CI 1.47-2.08). Women using depot medroxyprogesterone acetate contraception were at lower risk for BV (aHR 0.59, 95% CI 0.48-0.73). CONCLUSIONS: Vaginal washing and unprotected intercourse were associated with increased risk of BV. These findings could help to inform the development of novel vaginal health approaches for HIV-1 risk reduction in women.

BACKGROUND: Vaginal infections are common and have been associated with increased risk for acquisition of human immunodeficiency virus type 1 (HIV-1). METHODS: We conducted a randomized trial of directly observed oral treatment administered monthly to reduce vaginal infections among Kenyan women at risk for HIV-1 acquisition. A trial intervention of 2 g of metronidazole plus 150 mg of fluconazole was compared with metronidazole placebo plus fluconazole placebo. The primary end points were bacterial vaginosis (BV), vaginal candidiasis, trichomoniasis vaginalis (hereafter, "trichomoniasis"), and colonization with Lactobacillus organisms. RESULTS: Of 310 HIV-1-seronegative female sex workers enrolled (155 per arm), 303 were included in the primary end points analysis. A median of 12 follow-up visits per subject were recorded in both study arms (P = .8). Compared with control subjects, women receiving the intervention had fewer episodes of BV (hazard ratio [HR], 0.55; 95% confidence interval [CI], 0.49-0.63) and more frequent vaginal colonization with any Lactobacillus species (HR, 1.47; 95% CI, 1.19-1.80) and H(2)O(2)-producing Lactobacillus species (HR, 1.63; 95% CI, 1.16-2.27). The incidences of vaginal candidiasis (HR, 0.84; 95% CI, 0.67-1.04) and trichomoniasis (HR, 0.55; 95% CI, 0.27-1.12) among treated women were less than those among control subjects, but the differences were not statistically significant. CONCLUSIONS: Periodic presumptive treatment reduced the incidence of BV and promoted colonization with normal vaginal flora.

BACKGROUND: Vaginal infections are common and have been associated with increased risk for acquisition of human immunodeficiency virus type 1 (HIV-1). METHODS: We conducted a randomized trial of directly observed oral treatment administered monthly to reduce vaginal infections among Kenyan women at risk for HIV-1 acquisition. A trial intervention of 2 g of metronidazole plus 150 mg of fluconazole was compared with metronidazole placebo plus fluconazole placebo. The primary end points were bacterial vaginosis (BV), vaginal candidiasis, trichomoniasis vaginalis (hereafter, "trichomoniasis"), and colonization with Lactobacillus organisms. RESULTS: Of 310 HIV-1-seronegative female sex workers enrolled (155 per arm), 303 were included in the primary end points analysis. A median of 12 follow-up visits per subject were recorded in both study arms ([Formula: see text]). Compared with control subjects, women receiving the intervention had fewer episodes of BV (hazard ratio [HR], 0.55; 95% confidence interval [CI], 0.49-0.63) and more frequent vaginal colonization with any Lactobacillus species (HR, 1.47; 95% CI, 1.19-1.80) and H(2)O(2)-producing Lactobacillus species (HR, 1.63; 95% CI, 1.16-2.27). The incidences of vaginal candidiasis (HR, 0.84; 95% CI, 0.67-1.04) and trichomoniasis (HR, 0.55; 95% CI, 0.27-1.12) among treated women were less than those among control subjects, but the differences were not statistically significant. CONCLUSIONS: Periodic presumptive treatment reduced the incidence of BV and promoted colonization with normal vaginal flora. Vaginal health interventions have the potential to provide simple, female-controlled approaches for reducing the risk of HIV-1 acquisition.

Introduction. Male circumcision is being promoted for HIV prevention in high-risk heterosexual populations. However, there is a concern that circumcision may impair sexual function. Aim. To assess adult male circumcision's effect on men's sexual function and pleasure. Methods. Participants in a controlled trial of circumcision to reduce HIV incidence in Kisumu, Kenya were uncircumcised, HIV negative, sexually active men, aged 18-24 years, with a hemoglobin >/=9.0 mmol/L. Exclusion criteria included foreskin covering less than half the glans, a condition that might unduly increase surgical risks, or a medical indication for circumcision. Participants were randomized 1:1 to either immediate circumcision or delayed circumcision after 2 years (control group). Detailed evaluations occurred at 1, 3, 6, 12, 18, and 24 months. Main Outcome Measures. (i) Sexual function between circumcised and uncircumcised men; and (ii) sexual satisfaction and pleasure over time following circumcision. Results. Between February 2002 and September 2005, 2,784 participants were randomized, including the 100 excluded from this analysis because they crossed over, were not circumcised within 30 days of randomization, did not complete baseline interviews, or were outside the age range. For the circumcision and control groups, respectively, rates of any reported sexual dysfunction decreased from 23.6% and 25.9% at baseline to 6.2% and 5.8% at month 24. Changes over time were not associated with circumcision status. Compared to before they were circumcised, 64.0% of circumcised men reported their penis was "much more sensitive," and 54.5% rated their ease of reaching orgasm as "much more" at month 24. Conclusions. Adult male circumcision was not associated with sexual dysfunction. Circumcised men reported increased penile sensitivity and enhanced ease of reaching orgasm. These data indicate that integration of male circumcision into programs to reduce HIV risk is unlikely to adversely effect male sexual function.

OBJECTIVE: To determine whether cervical mucosal shedding of HIV-1 RNA and HIV-1 infected cells decreases following successful treatment of cervicitis. DESIGN: Prospective interventional study. SETTING: Sexually Transmitted Infections Clinic, Coast Provincial General Hospital, Mombasa, Kenya. PARTICIPANTS: Thirty-six HIV-1 seropositive women with cervicitis: 16 with Neisseria gonorrhoeae, seven with Chlamydia trachomatis, and 13 with non-specific cervicitis. INTERVENTIONS: Treatment of cervicitis. Main outcome measures: Levels of total (cell-free and cell-associated) HIV-1 RNA and presence of HIV-1 DNA (a marker for infected cells) in cervical secretions before and after resolution of cervicitis. RESULTS: After treatment of cervicitis, the median HIV-1 RNA concentration in cervical secretions was reduced from 4.05 to 3.24 log10 copies/swab (P = 0.001). Significant decreases in cervical HIV-1 RNA occurred in the subgroups with N. gonorrhoeae (3.94 to 3.28 log10 copies/swab; P = 0.02) and C. trachomatis (4.21 to 3.19 log10 copies/swab; P = 0.02). Overall, the prevalence of HIV-1 infected cells in cervical secretions also decreased after treatment, from 67% to 42% (odds ratio, 2.8; 95% confidence interval, 1.3-6.0; P = 0.009). Detection of infected cells was associated with higher mean HIV-1 RNA levels (4.04 versus 2.99 log10 copies/swab; P< 0.0001). CONCLUSIONS: Effective treatment of cervicitis resulted in significant decreases in shedding of HIV-1 virus and infected cells in cervical secretions. Treatment of sexually transmitted diseases may be an important means of decreasing the infectivity of HIV-1 seropositive women by reducing exposure to HIV-1 in genital secretions.

Cross-sectional analyses have demonstrated an association between use of hormonal contraceptives and shedding of herpes simplex virus (HSV). This prospective study evaluated the effect of initiating use of hormonal contraception on cervical HSV detection. Two hundred women who were seropositive for HSV-2 and human immunodeficiency virus (HIV) type 1 were examined for cervical mucosal HSV by use of quantitative DNA polymerase chain reaction before and after beginning the use of hormonal contraceptives. Cervical HSV was detected in 32 women (16.0%) before initiating and in 25 women (12.5%) after initiating use of hormonal contraception (P=.4). There were no significant differences in HSV shedding among the subgroups of women starting combination oral contraceptives containing both estrogen and progesterone or progesterone-only contraceptives. Among the 54 women who shed HSV at least once, the median change in cervical HSV after initiation of hormonal contraception was -313 copies/swab. In this prospective study, use of hormonal contraceptives did not increase detection of cervical HSV.

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.

J Immunol. 2007 Mar 15;17.". In: J Immunol. 2007 Mar 15;178(6):3750-6. John Benjamins Publishing Company; 2007. Abstract
HIV diversity may limit the breadth of vaccine coverage due to epitope sequence differences between strains. Although amino acid substitutions within CD8(+) T cell HIV epitopes can result in complete or partial abrogation of responses, this has primarily been demonstrated in effector CD8(+) T cells. In an HIV-infected Kenyan cohort, we demonstrate that the cross-reactivity of HIV epitope variants differs dramatically between overnight IFN-gamma and longer-term proliferation assays. For most epitopes, particular variants (not the index peptide) were preferred in proliferation in the absence of corresponding overnight IFN-gamma responses and in the absence of the variant in the HIV quasispecies. Most proliferating CD8(+) T cells were polyfunctional via cytokine analyses. A trend to positive correlation was observed between proliferation (but not IFN-gamma) and CD4 counts. We present findings relevant to the assessment of HIV vaccine candidates and toward a better understanding of how viral diversity is tolerated by central and effector memory CD8(+) T cells.

In: Pharmacogenetics. 1999 Dec;9(6):773-6. Douglas McLean Publishing; 1999. Abstract
Thiopurine methyltransferase (TPMT) degrades 6-mercaptopurine, azathioprine and 6-thioguanine which are commonly used in the treatment of autoimmune diseases, leukaemia and organ transplantation. TPMT activity is polymorphic as a result of gene mutations. Heterozygous individuals have an increased risk of haematological toxicity after thiopurine medication, while homozygous mutant individuals suffer life threatening complications. Previous population studies have identified ethnic variations in both phenotype and genotype, but limited information is available within African populations. This study determined the frequency of common TPMT variant alleles in 101 Kenyan individuals and 199 Caucasians. The frequency of mutant alleles was similar between the Caucasian (10.1%) and Kenyan (10.9%) populations. However, all mutant alleles in the Kenyan population were TPMT*3C compared with 4.8% in Caucasians. In contrast TPMT*3A was the most common mutant allele in the Caucasian individuals. This study confirms ethnic differences in the predominant mutant TPMT allele and the findings will be useful for the development of polymerase chain reaction-based strategies to prevent toxicity with thiopurine medications.

Catechol O-methyltransferase (COMT) inactivates neurotransmitters, hormones and drugs such as levodopa. COMT activity is inherited in an autosomal recessive manner and individuals with low activity have thermolabile COMT protein. A low activity allele has been demonstrated at codon 108/158 of the soluble and membrane bound COMT protein, respectively, whereby a G to A transition results in a valine to methionine substitution, rendering the protein more thermolabile. As ethnic differences in erythrocyte COMT activity have been previously demonstrated, the frequency of low activity alleles were investigated in 265 British Caucasian, 99 British South-west Asian and 102 Kenyan individuals. Genotyping of COMT codon 108/158 was performed using a minisequencing method. Erythrocyte COMT activity was measured in 60 British Caucasian individuals by radiochemical assay. The frequency of low activity alleles was 0.54 in Caucasians, 0.49 in South-west Asians, and 0.32 in Kenyans. There was a much lower frequency of individuals with homozygous low activity allele in the Kenyan population (9%) than in Caucasians (31%) or South-west Asians (27%). Erythrocyte COMT activity was lower and less thermostable in individuals with homozygous low activity alleles. The data provide molecular evidence that low COMT is less common in African individuals than the Caucasian population. PMID: 9682265 [PubMed - indexed for MEDLINE]

AIMS: Dihydropyrimidine dehydrogenase (DPD) reduces endogenous pyrimidines and therapeutic analogues such as the anticancer agent 5-fluorouracil (5FU). Among Caucasian populations DPD activity is highly variable and subject to polymorphic regulation. To evaluate interethnic influence, DPD activity was assessed in South-west Asian, Kenyan and Ghanaian populations. METHODS: DPD activity was determined in peripheral mononuclear cells using[14C]-5-fluorouracil and h.p.l.c. analysis. RESULTS: A high degree of variation in DPD activity was observed within each population (range CV = 34-48%). Median DPD activity also varied between these populations. South-west Asian and Kenyan subjects exhibited almost identical median values (192 and 193.5 pmol min(-1) mg(-1), respectively), which were similar to Caucasians (median 215 pmol min(-1) mg(-1). A significantly lower median DPD activity (119 pmol min(-1) mg(-1)) was observed in the Ghanaian population. CONCLUSIONS: The similarity in DPD activity between Caucasian, Kenyan and South-west Asian populations suggests that the incidence of 5FU-related toxicity may be comparable in these groups. The pharmacokinetic implications of lower activity amongst Ghanaians needs to be evaluated.

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

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

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

Abstract
Persistent microcytosis was noted among a number of post renal transplant patients attending the transplant clinic at the Western General Hospital Edinburgh. We retrospectively looked at the pattern of recovery of the anaemia of chronic renal failure following successful renal transplantation with good graft function (Creatinine less than 250 (mol/l). Comparisons were made between those patients with persistent microcytosis and those with normal mean cell volume (MCV). Patients with microcytosis tended to have a slower recovery compared to those with normal MCV especially from week 12 to 21 after transplantation with corresponding Hb changes of 108+ 20 to 126+/-20 g/l vs 128+ 17 to 144+/-19 g/l ([P < 0.05], 95% confidence limits). The microcytic groups also tended to have had poorer graft function with serum creatinines significantly higher than those with normal MCV from week 8 to 21, 182+/- 62 to 173+/- 51 (mol/1 vs 139+/- 40 to 149+/- 38 (mo1/L ([P < 0.05] 95% confidence limits). In both groups haemoglobin concentration was negatively correlated to serum creatinine. (r=-0.54, [P < 0.05]). Body iron status studies had not been done in these patients. Persistent microcytosis though a non sensitive marker of iron deficiency may be a marker of disordered iron metabolism in patients with poorer graft functions.

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

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

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

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

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

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

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

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

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

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

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

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

Forty seven patients with acute renal failure were studied prospectively over a two-year period at the Kenyatta National Hospital. There were 20 males and 27 females. The mortality rate was 40.4%. Most patients had medically oriented problems. Complications that were associated with a high mortality were infections and the presence of neuropsychiatric manifestations.

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

In a two-year-period (August 1984 to August 1986), 77 patients were admitted into the maintenance haemodialysis programme at Kenyatta National Hospital. 24 (31.5%) of these had ascites during haemodialysis. Nine (37.5%) of the patients who had ascites had prior peritoneal dialysis, while 15 (62.5%) had congestive cardiac failure at the time of development of the ascites. In 21 (87.5%), the ascites responded to therapy with diuretics, salt and fluid restriction, antibiotics when indicated and to ultrafiltration during dialysis. In 3 (12.5%) of the patients, the ascites developed in the absence of any predisposing cause. The ascites progressively increased in amount and was associated with marked wasting. These patients were considered to have refractory ascites of haemodialysis.

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

Renal biopsies were evaluated in 422 patients with nephrotic syndrome at the Kenyatta National Hospital between 1982 and 1993. Three hundred and fifty five (84.1%) of the patients were less than 30 years old (range: 7 months to 66 years; mean=SD: 28.4 - 9.2 years). The commonest histological lesions were mesangial proliferative glomerulonephritis (25.1%), minimal change nephropathy (17.5%) and focal segmental glomerulosclerosis (15.2%). Poststreptococcal aetiology was implicated in diffuse proliferative glomerulonephritis while use of skin lightening cosmetics appeared to play a role in the aetiology of minimal change nephrophathy in females. No aetiological role was apparent for hepatitis B virus, human immunodeficiency virus, malarial or schistosomal infection. All patients with minimal change nephropathy, focal segmental glomerulosclerosis and mesangial proliferative glomerulonephritis were treated with steroids and/or cytotoxics with a variable response.

Renal transplantation has become the most effective treatment for end stage renal failure. The numbers and survival rates of patients undergoing renal transplantation have increased immensely over the past decade. The use of immunosuppressive drugs has contributed greatly to the success of transplantation. Drugs such as azathioprine, corticosteroids, cyclosporin, FK 506, ATG/ALG and OKT3 are being used in several countries on a daily basis. New drugs and other modalities of immunosuppression are under investigation. This paper reviews these medications with respect to dosing, administration and adverse effects. Drugs being relatively expensive, the use of these drugs in developing counties is discussed.

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

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

A prospective study to determine the prevalence and profile of cardiovascular disease in elderly patients admitted into the medical wards, Kenyatta National Hospital, was carried out between July 1991 and January 1992. Two hundred and two patients over 60 years of age were admitted into the medical wards over this period. This formed seven per cent of the total medical admissions. Two of these refused to take part in the study. Of the 200 elderly patients evaluated for cardiovascular disease, 146 (73%) were between 60 and 75 years of age with only 26 (13%) being over 85 years. Fifty seven per cent were males. Clinical evidence of cardiovascular disease was present in 79 (39.5%) of the patients evaluated. There was no sex difference in the prevalence of cardiovascular disease as judged from clinical evaluation (37.7% males versus 41.9% females, p > 0.05). Cardiovascular diseases in our medical in-patients at Kenyatta National Hospital are common and especially so with hypertension which plays an important role in the aetiology of congestive heart failure and cerebravascular accidents. Cardiac arrhythmias are also common though not necessarily symptomatic. Rheumatic heart disease and cardiomyopathies were uncommon in our study population. A community-based survey is needed to determine the true prevalence of cardiovascular diseases in the elderly and their contribution to morbidity in this sector of the population.

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

One hundred consecutive patients with diabetic ulcers were studied in an 8-month-period. There were 58 females. The mean age was 59.9 years. Eighty three patients had non-insulin dependent diabetes mellitus. The mean duration of diabetes mellitus was 11.6 years. The mean duration of the ulcer was 8.5 months. Sixty nine of the ulcers were gangrenous. Over 50% of the ulcers involved the big toes. Neuropathic ulcers were found mainly in the sole of the feet. Roentgenograms showed evidence of osteomyelitis in 44 patients. There were 356 bacterial isolates (340 aerobes and 16 anaerobes) from the ulcers. There were 3.6 infecting organisms per ulcer in gangrenous ulcers, while in neuropathic ulcers, there were 3.4 infecting organisms per ulcer. In both types of ulcer Staphylococcus aureus and Escherichia coli were the commonest infecting organisms each being isolated in 88 of the 100 ulcers studied. In repeat bacterial cultures at 4 weeks there were 116 bacterial isolates. Staphylococcus aureus persisted in 63 ulcers despite therapy, while Escherichia coli persisted in 35. There were no new organisms isolated at repeat cultures and no ulcer was completely sterile. The Staphylococcus aureus was 100% sensitive to Augmentin (Amoxicillin plus clavulinic acid), Clindamycin, Novobiocin, and Amikacin while the gram negative bacilli were sensitive to Cefotaxime, Piperacillin, Amikacin and augmentin, Clindamycin, Chloramphenicol and Lincomycin inhibited the growth of anaerobes to a varying degree.

In a fifteen month period (August 1987 to November 1988) forty patients requiring haemodialysis had 83 angioaccess procedures performed. Arteriovenous (AV) shunts and arteriovenous fistulae were the commonest procedures, comprising 56 (67%) and 20 (24%) of the patients respectively. Subclavian catheters and artificial grafts were used less frequently. Nephrologists and senior house officers attached to the Renal Unit were responsible for fashioning A-V shunts and inserting subclavian catheters while the A-V fistulae were fashioned by the urologists and vascular surgeons. The commonest complication of A-V shunts were clotting, occurring in 31 (55.4%) followed by bleeding in 14 (25%). Eight (32%) of the A-V fistulae never functioned from the beginning. It is noted that we are still very dependent on A-V shunts for vascular access in end stage renal disease (ESRF) patients and this is associated with an unacceptable level of complications. This dependency on A-V shunts in ESRD patients should be stopped or phased out. A-V fistulae should be used more frequently. Their constructions should be well thought out, executed and supervised by the few surgeons who are versed in them together with their follow-ups.

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

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

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

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

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.

"MDR1 pharmacogenetics: frequency of the C3435T mutation in exon 26 is significantly influenced by ethnicity." Pharmacogenetics. 2001;11(3):217-21. Abstract

P-glycoprotein (PGP), the product of the multidrug resistance gene (MDR1), acts as an energy-dependent efflux pump that exports its substrates out of the cell. PGP expression is an important factor regulating absorption of a wide variety of medications. It has also been associated with intrinsic and acquired cross resistance to a number of structurally unrelated anticancer drugs. A single nucleotide polymorphism (SNP) in exon 26 of the MDR1 gene, C3435T, was recently correlated with PGP protein levels and substrate uptake. Individuals homozygous for the T allele have more than four-fold lower PGP expression compared with CC individuals. As overexpression of PGP has been associated with altered drug absorption, therapy-resistant malignancies, and lower concentrations of HIV-1 protease inhibitors, this SNP may provide a useful approach to individualize therapy. To facilitate clinical application throughout the world, 1280 subjects from 10 different ethnic groups were evaluated for this SNP using the polymerase chain reaction-restriction fragment length polymorphism assay and the genotype and allele frequency for each group were ascertained. Marked differences in genotype and allele frequency were apparent between the African populations and the Caucasian/Asian populations (P < 0.0001). The Ghanaian, Kenyan, African American and Sudanese populations studied had frequencies of 83%, 83%, 84% and 73%, respectively, for the C allele. The British Caucasian, Portuguese, South-west Asian, Chinese, Filipino and Saudi populations had lower frequencies of the C allele compared to the African group (48%, 43%, 34%, 53%, 59%, and 55%, respectively). The high frequency of the C allele in the African group implies overexpression of PGP and may have important therapeutic and prognostic implications for use of PGP dependent drugs in individuals of African origin.

Bovine foscioliosis coused by F. giganticais widespread in   There is a large collection of reports of fasciolosis in Kenya based on  abattoir data records from veterinary investigation laboratories (VILS) as well as reports on a few farm study was carried out to improve on the reports.  Diagnosis of fasciola infection has traditionally been based on detection of typical eggs in the faeces.  A variety of other techniques are now available eg enzyme-linked immunosorbent assay (ELISA), which has shown to be sensitive and useful. Three agro-ecological zoned were defined depending on the reported prevalence; high risk, medium risk and low risk zones.  Two study districts were picked at random from each zone.  The study farms were selected using the two stage cluster sampling. Faecal and blood samples were collected on the farm.  Serum was later harvested.  ELISA and faecal sedimatation tests (FST) were carried out. A total of 2434 faecal and blood samples were screened.  ELISA achieved the highest (66%) positive rate of the samples from Kwale district and the lowest (23%) rate in Nakuru.  An overall positive prevalence of (43%) for fasciolosis was achieved.  The faecal sedimentation test showed prevalence of 19%.  In both tests high prevalence were observed in Kwale and Kilifi districts.  ELSA was always positive when FST was positive but not the converse. The on-famr survey utilizing two reliable diagnostic tests was meant to improve on existing abattoir reports.  Both tests showed fair to good agreements.  The higher detection by ELISA might be due to deworming and other reasons.  It was concluded that on-farm surveys are better than retrogressive studies; thought the latter are cheaper and faster.,  the current prevalence of fasciolosis are different from past reports with coastal showing higher than expected prevalences.

Largerkvist CJ, Ngigi MW, Karanja N. "Means-end chain analysis explains soil fertility management decisions by peri-urban vegetable growers in Kenya.". 2013. Abstract

Past studies of the use of soil fertility management strategies by farmers usually model input use decisions based on the neoclassical utility/profit maximization principle in which farmers use soil fertility management inputs primarily to increase revenues and profits. However, there is, to date, no study that explains exactly how this decision-making process occurs and the role which personal values play in driving the choice of soil fertility management inputs. This article systematically maps the relationship between choice of soil fertility management strategy (attributes), its outcomes (consequences) and the personal values that motivate the choice. It specifically uses the means-end chain approach to construct hierarchical value maps that relate the attributes to consequences, and ultimately to the personal values. The study finds that the use of soil fertility management strategies by peri-urban fresh vegetable growers is driven by five personal values, namely happiness, comfortable life, independence, good/healthy life and achievement of life goals. It also finds that while farmers seek to increase profit (hence incomes), profit maximization is not the end driver of the use of soil fertility management inputs. It concludes that a lot more goes into farmers’ decision-making process relating to the use of soil fertility management practices than can be explained by the neoclassical profit/utility maximization principle. The study discusses the policy implications of these findings.

Lagerkvist CJ, Ngigi M, Okello J, Karanja N. "Means-End Chain approach to understanding farmers’ motivations for pesticide use in leafy vegetables: The case of kale in peri-urban Nairobi, Kenya.". 2012. Abstract

Peri-urban farmers play a significant role in the production of vegetables consumed in the urban centers in most African countries. The production of vegetables in the peri-urban areas in these countries is strategic with most farmers targeting the lucrative and better-paying urban markets. However, the decline in agricultural land in the peri-urban due to competition from housing for urban workers has led peri-urban farmers to use intensive means of agricultural production. Decreasing land sizes imply that peri-urban lands are continuously under production resulting in the build-up of pests and diseases. Further, the tropical climate generally increases the outbreak and rapid multiplication of pests and diseases. These problems and the urban consumers’ demand for clean and spotlessness vegetables encourage the excessive use of pesticides. Additionally, the desire to reduce losses and waste can cause farmers to violate the recommended intervals between pesticide application and harvest. Consequently, there have been concerns about the excessive application of pesticides in vegetables produced in the peri-urban areas. The study applies the Means-End Chain (MEC) approach accompanied by the laddering technique to assess the motivations for peri-urban farmers to use pesticides as opposed to other crop protection methods in the production of fresh vegetables. It specifically examines the relevant attribute econsequenceevalue relations by setting up relevant hierarchical value maps. The study is based on a random sample of 54 kale farmers in three peri-urban areas of Nairobi. It finds that farmers apply pesticides at different times mainly for the purpose of improving their efficacy in protecting kale against pests and diseases. Protection of kale improves its aesthetic quality attributes resulting in higher prices and hence profit margins. Examination of the hierarchal value maps further reveals that the other motivations for pesticide use include benevolence value (being helpful and honest to trading partners), power (social recognition or good reputation as a good farmer), hedonism (happiness for being a successful farmer), security (having good health) and self-direction (independence or being self-supporting from vegetable income). Clearly, the motivations suggest a dilemma in safe use of pesticides. While some motivators dictate less use of pesticides, others can promote indiscriminate use of pesticides. The study discusses the implication of these findings for sustainable and environmentally friendly production of safe leafy vegetables in peri-urban areas.

Oluoch-Kosura W, Siele DK, Owuor PO, Kavoi MM. "A Measure of Economic Rationality in the Smallholder Tea Sub-Sector in Kenya.". 2001. Abstract

The smallholder tea sub-sector in Kenya is considered the largest and one of the most successful smallholder schemes in the world. However, tea productivity in this sub-sector has been persistently low when compared with the estate sub-sector. Despite the smallholders planting high yielding clonal teas, the national average yield in the sub-sector was only 2,075 kg made tea/hectare (mt/ha) compared to 3,954 kg mt/ha in the estate sub-sector in 1998. This study investigated some of the factors contributing to low tea productivity in the sub-sector. Cross sectional data gathered in Kirinyaga, Nyambene, Nandi and Nyamira Districts in 1999 were used. It was hypothesized that the extend of rationality in allocation of resources in the smallholder tea enterprise is relatively low. Hence, smallholder tea productivity has remained relatively lower than in the estate sub-sector, high yielding clones and useful agronomic recommendations extended in the smallholder sub-sector notwithstanding. To determine \"the extend of economic rationality\", \"A Test of Economic Rationality Model\" was used whereby, the index of economic rationality, ρ is the product moment coefficient of correlation between log (total variable costs-excluding labour costs) and log (labour-in mandays) for each tea district and region. The results showed that the product moment coefficient of correlation, ρ was:- 0.647 in Kirinyaga District, 0.651 in Nyambene District, 0.793 in Nandi District, 0.743 in Nyamira District, 0.595 in East Rift Valley Region, 0.752 in West Rift Valley Region and 0.674 for all farms surveyed. It was noted that the lowest value of ρ was 0.595 in East Rift Valley Region. It means that at least 59 percent of the variance in the logs of both inputs is due to the variation in the systematic profit-maximizing component of these inputs. The balance of 41 percent is the maximum that could be occasioned not only by poor technology and/or knowledge gaps but also by errors in the model and noise in the universe. The null hypothesis was rejected in favour of the alternative hypothesis. The conclusion is that smallholder tea farmers in Kenya seem to be quite price efficient in tea production.

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.

This report concerns an outbreak that occurred during July/August 1997. Ten pigs from a herd of 181 pigs in a medium-scale, semi-closed piggery in Kiambu District, Kenya, contracted the clinical disease. The main clinical findings in affected pigs included: fever (40.5-41.8 degrees C), prostration, inappetence, dog-sitting posture, abortion, erythema and raised, firm to the touch and easily palpated light pink to dark purple diamond-shaped to square/rectangular spots on the skin around the belly and the back. Based on the pathognomonic skin lesions, a clinical diagnosis of swine erysipelas was made. The diagnosis was confirmed by the isolation of Erysipelothrix rhusiopathiae organisms from the blood and skin biopsies taken from the affected pigs. Response to treatment with a combination of procaine penicillin and dihydrostreptomycin at the dosage rate of 20,000 IU/kg body weight (based on procaine penicillin) for 3 days was good and all the affected pigs recovered fully. The farm was placed under quarantine to prevent spread of the disease
Magoha GAO. "Measurement of serum C-Reactive protein concentration after renal transplantation. ." Journal of Nephrology, Dialysis and Transplantation 2. 1987:39-41. Abstract

A prospective study of serial serum C-reactive protein (CRP) concentrations was made on 21 patients who had received renal allografts. CRP was raised during 27 of 32 rejection episodes and in all of five episodes of rejection associated with infection. CRP values were persistently elevated in three irreversible rejection episodes. Significantly raised CRP concentrations were documented in 14 of 20 episodes of infection. In some cases CRP was a predictive indicator of rejection or infection. In all cases of infection or rejection associated with a rise in CRP, CRP values fell following successful treatment with appropriate agents. Serial CRP measurement used in conjunction with other clinical and biochemical parameters appears to be valuable clinically following renal transplantation.

The microbiological quality of ground water (boreholes) and domestic tanks in five locations of Kikuyu Division, Kiambu District, was determined. Two boreholes and twelve domestic tanks were sampled from each location. Seven (70%) out of 10 boreholes were contaminated with faecal coliforms. Total bacterial counts ranged from 1 to 6280 per ml of water while the coliform counts ranged from 0 to 161. Out of 70 water samples screened for faecal coliforms, 63 (90%) were positive. Faecal Streptococci were isolated in 71% of the samples.

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.

A preliminary study of microbiological quality of honey was carried out using 26 samples obtained from the National Bee Keeping Research Station. Total viable counts (TVC) of aerobic bacteria, yeasts and moulds, and Clostridium species were done. Of the 26 samples, 24 (92.3%) had a TVC ranging from 3 x10 -87 x 10 colony forming units (cfu) per gram of honey. Two samples did not yield any microorganisms. Of the 24 positive samples, 9 (37.5%) were found to contain Clostridium species per gram while eight (33.3%) were positive for moulds with counts ranging from 10-100 c.f.u / g. No yeasts were detected. In addition, three samples yielded the three types of microorganisms.

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.
