Gichaga FJ. Evaluation of flexible road pavements in Kenya.; 1983. Abstract

Experience from some of the recently completed roads shows that road pavements have at times failed prematurely thereby leading to unplanned expenditure in the exercise of rehabilitating them. This paper outlines results of studies carried out to establish long-term behaviour of road pavements under tropical climatic conditions. The studies involved measurements of elastic deflections, pavement distortion and rutting, cracking as well as establishing traffic loading patterns for typical high standard trunk roads of varying design in Kenya. The results of the studies show that while pavements are weakened by repeated wheel load applications pavements also tend to develop strength with age. The results further showed that for a pavement approaching failure elastic deflections are a function of cracking and rutting; and that higher elastic deflections are obtained during the months of high rainfall and high temperatues. The paper recommends that there is need for road authorities to regularly monitor factors that relate to road pavement performance such as traffic loading, pavement condition, etc. in order to help in the financial planning for pavement strengthening and maintenance works and that the necessary funds should be set aside in the budget.

Gichamba A, Wagacha PW, Ochieng DO. "An Assessment of e-Extension Platforms in Kenya." International Journal of Innovative Studies in Sciences and Engineering Technology (IJISSET). 2017;3:36-40. Abstract

The use of ICT in agriculture within developing countries has quickly gained popularity among development agencies, the private sector and even the government. ICT for agriculture (ICT4Ag) services such as trade platforms, notification platforms and advisory/extension services have been developed. This has been catalyzed by the growing number of farmers with access to ICT devices such as mobile phones. Among the available services, advisory/extension platforms have gained popularity among farmers and agriculture stakeholders in the developing world. These platforms have proven to be of importance to farmers who are curious about new farming methodologies, strategies to improve their yields, breeding techniques, among other factors. The ICT platforms employed include SMS, mobile applications, Interactive Voice Response systems, social media platform such as Facebook and Twitter, chat applications such as Whatsapp, blogs, radio programs and tv programs. The aim of this research was to assess the e-Extension platforms used in Kenya, whose purpose is to advise millions of farmers across different parts of the country using ICT platforms. 28 government e-Extension officers employed to advise farmers using ICT platforms were interviewed. The officers represented 15 different counties in Kenya. The study made important findings that would inform the government, agriculture extension content providers, and other stakeholders on critical aspects to be considered in deploying and managing eextension platforms among a population of diverse users within a developing country.

Gichangi PB, Karanja JG, Kigondu CS, Fonck K, Temmerman M. "Knowledge, attitudes, and practices regarding emergency contraception among nurses and nursing students in two hospitals in Nairobi, Kenya." Contraception. 1999;59(4):253-6. Abstract

A cross-sectional descriptive study on knowledge, attitudes, and practice about emergency contraception (EC) was conducted among nurses and nursing students using a self-administered questionnaire. One-hundred-sixty-seven qualified nurses and 63 nursing students completed the questionnaire. Over 95% listed at least one regular contraceptive method but only 2.6% spontaneously listed EC as a contraceptive method, whereas 48% of the respondents had heard of EC. Significantly more nursing students than qualified nurses were familiar with EC. Knowledge about the types of EC, applications, and side effects was poor and 49% of the respondents considered EC as an abortifacient. Of those familiar with EC, 77% approved its use for rape victims and 21% for adolescents and schoolgirls. Only 3.5% of all respondents had personally used EC in the past, 23% of those familiar with EC intend to use it in the future, whereas 53% intend to provide or promote it. The view that EC was abortifacient negatively influenced the decision to use or provide EC in the future. The present findings suggest that the level of knowledge of EC is poor and more information is needed. These findings indicate the potential to popularize emergency contraception in Kenya among nurses and nursing students.

ABSTRACT
Objective: Invasive cervical cancer (ICC) and HIV are common in sub-Sahara Africa.
Both ICC and HIV are immunosuppressive, and are associated with decreased CD4
and CD8 profiles. In a group of women with ICC starting radiotherapy, we determined
their CD4 profiles.
Design: This was a cross-sectional study design.
Settings: Kenyatta National Hospital, Nairobi, Kenya, radiotherapy unit.
Subjects: Women with invasive cervical cancer (344) seeking radiotherapy treatment
for the first time between January 2000 and March 2003, had blood samples analyzed
for CD4 and CD8 cell counts by flow cytometry. Haemoglobin, white cell count,
lymphocyte and platelet counts were determined using coulter machine. All patients
had received pre- and post HIV counseling.
Results: The mean age was 49+13 years. About 13.1% of the women with ICC were
HIV positive. Overall, mean and median CD4 cell count was 829+355 cells/mm3 and
792 cells/mm3. Among HIV+ patients, mean and median CD4 cell counts were 451+288
cells/mm3 and 405 cells/mm3 respectively. The mean CD4 cell count for the HIV+women was 886+329 cells/mm3 with median of 833 cells/mm3, range 147-2065 cells/mm3.
Only nine (20%) of the 45 HIV+ women had CD4 cell count of 0-200. HIV+ women
had lower CD4 percentage and cell count and higher CD8 percentage and cell count
as compared to HIV negative women, p < 0.001. HIV infection was significantly and
independently associated with high proportion of women who had CD4 cell count of
less than 200 cells/mm3 or less than 350 cells/mm3, p < 0.0001.
Conclusions: Women with ICC and concurrent HIV infection have decreased CD4 cell
subset. These results suggest HIV infection may be associated with more severe CD4
depletion in women with ICC.

Invasive cervical cancer (ICC) is common in areas where human immunodeficiency virus (HIV) is also prevalent. Currently, HIV seroprevalence as well as acceptability of HIV testing in ICC patients in Kenya is unknown. The objective of this study was to determine the acceptability of HIV testing among patients with ICC. Women with histologically verified ICC at Kenyatta National Hospital participated in the study. A structured questionnaire was administered to patients who gave informed consent. HIV pre- and posttesting counseling was done. Blood was tested for HIV using enzyme-linked immunosorbent assay. Overall, 11% of ICC patients were HIV seropositive. The acceptance rate of HIV testing was 99%; yet, 5% of the patients did not want to know their HIV results. Patients less than 35 years old were two times more likely to refuse the result of the HIV test (odds ratio [OR] 2.2). Patients who did not want to know their HIV results were three times more likely to be HIV seropositive (OR 3.1). Eighty four percent of the patients were unaware of their HIV seropositive status. The HIV-1 seroprevalence in ICC patients was comparable to the overall seroprevalence in Kenya. ICC patients were interested in HIV testing following pretest counseling. Offering routine HIV testing is recommended in ICC patients.

Gichangi P, Apers L, Temmerman M. "Rate of caesarean section as a process indicator of safe-motherhood programmes: the case of Kenya." J Health Popul Nutr. 2001;19(2):52-8. Abstract

The study assessed the value of currently-available data on the rates of caesarean section as an indicator of safe-motherhood programmes. Data, collected through the routine health information system of the Ministry of Health, Kenya, were used for analyzing the available process indicators. The methodology of this study illustrates both usefulness and limitations of readily-available healthcare information. The rate of hospital-based caesarean section was 6.3% of all births (range 0.3-37%), whereas the rate of population-based caesarean section was 0.95% (range 0.1%-4%). The rate of population-based caesarean section indicates a significant unmet need for obstetric care in the rural areas and may be a useful tool for monitoring progress on safe-motherhood initiatives in poor settings. Rates of population-based caesarean section are low in Kenya, especially in the rural areas. The rate of caesarean section may be a valuable process indicator for identifying the gaps in obstetric care and may be used for advocating improvements for healthcare to the relevant authorities.

Invasive cervical cancer (ICC) is the leading cause of cancer-related death among women in developing countries. Population-based cytologic screening and early treatment does reduce morbidity and mortality associated with cervical cancer. Some of the factors related to the success of such a program include awareness about cervical cancer and its screening. The objective of this study was to assess knowledge and practice about cervical cancer and Pap smear testing among cervical cancer and noncancer patients using a structured questionnaire to obtain information. Fifty-one percent of the respondents were aware of cervical cancer while 32% knew about Pap smear testing. There were no significant differences in knowledge between cervical cancer and noncancer patients. Health care providers were the principal source of information about Pap testing (82%). Only 22% of all patients had had a Pap smear test in the past. Patients aware of cervical cancer were more likely to have had a Pap smear test in the past. The level of knowledge is low among ICC and noncancer patients. There is need to increase the level of knowledge and awareness about ICC and screening among Kenyan women to increase uptake of the currently available hospital screening facilities.

Gichangi PB, Nyongo AO, Temmerman M. "Pregnancy outcome and placental weights: their relationship to HIV-1 infection." East Afr Med J. 1993;70(2):85-9. Abstract

The relationship between placental characteristics, including weight and inflammation, and pregnancy outcome was examined as part of a case control study looking into the impact of maternal HIV-1 infection on pregnancy outcome. Cases defined as low birth weight (< 2500g) or stillbirth deliveries, were compared to controls defined as mothers who delivered a live born neonate weighing 2500g or more. The mean placental weight and the mean foetal/placental weight ratio were significantly lower in cases (n = 253) than in controls (n = 216) (p < .05). Placental inflammation (chorioamnionitis) was significantly associated with prematurity (p < .001) and with stillbirth (p < .05), maternal HIV-1 antibody being a risk factor for chorioamnionitis in the preterm group. These data support a correlation between placental weight and pregnancy outcome, and suggest that maternal HIV-1 infection is a risk factor for chorioamnionitis in HIV-1 seropositive preterm deliveries.

We examined partner notification among syphilitic pregnant women in Nairobi. At delivery, 377 women were found to be rapid plasma reagin (RPR) reactive. Data were available for 94% of the partners of women who were tested during pregnancy; over 67% of the partners had received syphilis treatment while 23% had not sought treatment mainly because they felt healthy. Six per cent of the women had not informed their partners as they feared blame and/or violence. Adverse pregnancy outcome was related to lack of partner treatment during pregnancy (7% versus 19%, odds ratio (OR) 3.0, 95% confidence interval (CI) 0.9-10.0). Our data suggest that messages focusing on the health of the unborn child have a positive effect on partner notification and innovative and locally adapted strategies for partner notification need more attention.

Livestockmanure is a valuable source of plant nutrients for crop production in the Central Kenyan highlands but its quality in terms of available nitrogen is low due to considerable nitrogen losses through ammonia olatilization. This study aimed at assessing the potential of agro-organic wastes to reduce nitrogen losses from manure heaps during the storage period. Three organic amendments selected from a laboratory simulation experiment were evaluated under farmers' conditions based in Karura, Kiambu District for their ability to reduce nitrogen losses from cattle manure heaps. The effect of a polyethylene sheet covering of manure heaps on nitrogen retention was also determined. There were eight treatments that comprised three agro­organic amendments (maize stover, coffee pulp and sawdust) and the control. Agronomic effectiveness of the treated manure samples and N uptake by maize seedlings were evaluated in a glasshouse experiment. 19% and 46% of the initial nitrogen respectively. Maize growth improved significantly (p:s;0.05) with increasing rates of manure irrespective of the organic treatments except for manure amended with sawdust. Treatments that received the recommended rate of nitrogen at 100 kg N ha-' had significantly higher (p:S;0.05) biomass of 21.55 g/p1ant while the control produced 2.78 g/p1ant only. Nitrogen uptake increased with increasing rates of manure and was higher (p-;O.O5) with manure amended with coffee pulp. Covering manure heaps to reduce moisture loss would also be beneficial in reducing nitrogen losses.

Gicheru PT, Gachene CKK. "Effects of soil management practices and tillage systems on soil moisture conservation and maize yield on a sandy loam in semiarid Kenya.". 2005. Abstract

Maize is an important crop in the high and medium rainfall areas of Kenya and thus, there is a need for additional information on the effect of tillage and soil management practices on water conservation and yield of maize. The objective of this study was to determine the effects of seven soil management practices: bare with conventional tillage (BC), bare with minimum tillage (BM), incorporated mulch with conventional tillage (IMuC), manure with conventional tillage (MaC), manure with minimum tillage (MaM), surface mulch with conventional tillage (SMuC), and surface mulch with minimum tillage (SMuM) on water conservation and yield of maize. Soil water content was greater in minimum tilled plots than in the conventionally tilled (hand hoeing) plots during the study period. This was demonstrated by the manure with minimum tilled treatment, which had the highest soil moisture (7.6% and 8.3%) both at 0-7 cm and 7-23 cm depth. However, when organic matter additions were analyzed separately, it was observed that manure irrespective of tillage had the highest soil moisture in both depths (7.6% and 8.1%). The differences within the treatments occurred when soil water contents were highest shortly after the rains. When the amount of soil water for each management practice was averaged for all the seasons, a significant difference was found at P = 0.0001. Manure (Ma) and surface mulched (Smu) treatments had significantly higher soil moisture content than the other treatments. The higher moisture content found under these treatments was attributed to higher infiltration rates, better cover that reduced the rainfall kinetic energy, and to better structural stability contributed to by higher organic carbon. Compared with the traditional form of hand hoeing, minimum tillage increased available soil water content drastically and crop performance was improved. Grain yields were greatest in manure and lowest in bare treatments. There were significant differences in grain yield in all treatments.

Gicheru MM, Olobo JO, Kariuki TM, Adhiambo C. "Visceral leishmaniasis in vervet monkeys: immunological responses during asymptomatic infections." Scand. J. Immunol.. 1995;41(2):202-8. Abstract

Nine vervet monkeys (Cercopithecus aethiops) were infected intradermally with 8 x 10(7) virulent L. donovani promastigotes. Four animals developed clinical visceral leishmaniasis and died over a period of 18 months. The remaining five animals have remained asymptomatic for a period of 3 years now. Attempts to isolate parasites from spleen and liver through biopsies were fruitless. Immunological responses of these subclinically infected animals were examined. Enzyme-linked immunosorbent assay (ELISA) and western blot analyses demonstrated Leishmania specific antibodies in these animals, but the antibody titres were low. When proliferation of peripheral blood monocytes (PBMC) to Concanavalin A (Con A) of these animals was compared with control 'disease free animals' there were no significant differences in response. However, L. donovani antigen (fixed promastigotes) specific proliferation was demonstrated in the five subclinically infected animals. High and varying levels of interferon gamma (IFN-gamma) were secreted in PBMC cultures from the five vervet monkeys when stimulated with either Con A or L. donovani antigens. In control animals, IFN-gamma was only detected when PBMC were stimulated with Con A. Marked delayed-type hypersensitivity (DTH) responses were demonstrated in the five subclinically infected animals 48 h after injection with formalin fixed promastgotes. It was concluded that the visceral Leishmania disease spectrum due to L. donovani observed in humans could be induced in vervet monkeys and that L. donovani asymptomatic/cryptic infected animals have competent humoral and cellular responses to homologous parasites.

This article looks at the current climate finance architecture and its impact on developing countries climate
change responses. The primary aim is to capture the contradictions that exist in the climate finance architecture
particularly between those recommended by the United Nations Framework Convention on Climate Change
(UNFCCC) and those advanced by developed countries otherwise known as non-UNFCCC climate financing
mechanisms. The overall observation is that once non-UNFCCC climate financing mechanisms emerged and the
more they were justified using the UNFCCC, the global response to the climate change problem was fatally
wounded through a procedural derailment of UNFCCC objectives. This article calls for a review of nonUNFCCC
with the aim of divesting them of the profit factor which in this case is the problematic.

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.

Objective: To determine the pattern of breast disease at Kenyatta National Hospital (KNH) Study design:    Retrospective descriptive study Study setting:    Kenyatta National Hospital, a University teaching and National Referral Hospital Patients: Records of 1172 patients were reviewed. Results: An average 469 new patients per year or 11 new patients per clinic visit were seen at the clinic over a two and a half year period. Females predominated (98.9%) in this series. The mean age was 34.71 years (range 1 to 96 years). The average age at menarche was 14.49 years and the mean duration of symptoms was 6.86 months. Only 2.6% of 843 patients had a positive family history of breast disease. Fibroadenoma was the commonest diagnosis made (33.2%) followed by ductal carcinoma (19.7%). Gynaecomastia was the most common lesion seen in males. Two thirds of patients presenting with tumors had masses measuring more than 5cm.  Overall five conditions (fibroadenoma, ductal carcinoma, breast abscesses, fibrocystic disease and mastalgia) accounted for over 85% of all breast ailments. Surgery formed the main stay of care in over 80% of patients. Conclusions: The pattern of breast diseases at KNH closely mirrors those reported in other studies in the region and beyond.

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.

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.

The study was carried out between November 2008 and April 2009 to investigate the occurrence and pathology due to Echinostomum revolutum in free-range indigenous chickens. One hundred and fifty six (156) indigenous chickens were purchased from various farms and markets in A thorough post mortem examination was performed on each bird and the isolated worms from the ceaca, large intestines, cloaca and oviduct were identified and quantified.  Tissues were collected for histopathology, processed, examined and the severity of the lesions determined. Echinostoma revolutum was recovered in 3/156 (1.9 %) birds examined in the ceaca and large intestines but not in cloaca and oviduct. Affected birds originated from market birds in Kiambu. They caused heamorrhages and typhylo-enteritis in the affected birds. Other worms observed from these organs were Ascaridia galli, Heterakis gallinarum, Heterakis isolonche, Heterakis dispar, Subulura brumpti, Raillietina echinobothrida and Hymenolepis contaniana. The trematodes are reported in Kenya for the first time.

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.

This study was carried out to verify the possibility that ducks are sources of Newcastle disease (ND) virus infection for chickens in mixed flocks. Immunosuppressed (IS) and non immunosuppressed (NIS) birds, at three different antibody levels (medium, low and absent) were used; the titres having been induced through vaccination, and Immunosuppression done using dexamethazone. Each of the 3 respective groups was further divided into 2 groups of about 12 ducks each: one challenged with velogenic ND virus; the other not challenged. Selected ducks fromall groups had their antibody titres monitored serially using hemagglutination inhibition test, while two birds from each of the challenged groups were killed and respective tissues processed for ND viral recovery, using chicken embryo fibroblasts. In general, antibody titres of IS and NIS challenged ducks were significantly higher than their unchallenged counterparts (P<0.05). Non-challenged pre-immunised ducks had a progressive decrease in antibody levels; non-immunised ducks did not seroconvert. Newcastle disease virus was isolated from livers and kidneys of the challenged ducks throughout the experimental period; indicating a possibility of viral excretion, especially when the birds are stressed. It, therefore, provides another possible model of viral circulation within mixed flocks.

Objective: To determine the pattern of breast disease at Kenyatta National Hospital (KNH) Study design:    Retrospective descriptive study Study setting:    Kenyatta National Hospital, a University teaching and National Referral Hospital Patients: Records of 1172 patients were reviewed. Results: An average 469 new patients per year or 11 new patients per clinic visit were seen at the clinic over a two and a half year period. Females predominated (98.9%) in this series. The mean age was 34.71 years (range 1 to 96 years). The average age at menarche was 14.49 years and the mean duration of symptoms was 6.86 months. Only 2.6% of 843 patients had a positive family history of breast disease. Fibroadenoma was the commonest diagnosis made (33.2%) followed by ductal carcinoma (19.7%). Gynaecomastia was the most common lesion seen in males. Two thirds of patients presenting with tumors had masses measuring more than 5cm.  Overall five conditions (fibroadenoma, ductal carcinoma, breast abscesses, fibrocystic disease and mastalgia) accounted for over 85% of all breast ailments. Surgery formed the main stay of care in over 80% of patients. Conclusions: The pattern of breast diseases at KNH closely mirrors those reported in other studies in the region and beyond. This study indicates that a large proportion of patients presenting with breast disease are treated initially by surgery.

bstract Localization of Newcastle disease viral nucleoprotein and pathological lesions was evaluated in tissues of 55 indigenous ducks (45 experimentally infected and 10 sentinel ones). In addition, ten Newcastle disease infected chickens were used to ensure that the virus inoculum administered to the ducks produced the disease in chickens, the susceptible hosts. Ducks were killed on day 1, 4, 8 and 14 post-infection. Postmortem examination was done with six tissues (liver, spleen, lung, caecal tonsils, kidneys and brain) being collected from each bird. The tissues were preserved in 10% neutral formalin for 24 h. They were then transferred to 70% ethanol for histology and immunohistochemical staining. Airsacculitis, necrotic splenic foci, congested intestines, lymphoid depleted caecal tonsils and focal infiltrations by mononuclear cells were the main pathological lesions in infected ducks. Over 28.9% of the infected ducks had Newcastle disease viral nucleoprotein in macrophage-like large mononuclear cells in the caecal tonsils and kidney tubular epithelium. The viral antigens were located in the cytoplasm and nucleolus of the cells. The other organs had no detectable viral antigens. This study shows that the kidneys and caecal tonsils are the likely predilection sites for the virus in ducks. They thus need to be considered as diagnostic indicators for the viral carriage in ducks

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.

In: Livestock research for Rural development. Livestock research for Rural Development; 2011. Abstract
Indigenous chickens constitute over 81% of poultry in Kenya and produce 71% of eggs and poultry meat. Ecto- and haemoparasites limit production of these birds in the rural areas. However, there exists scanty information on these parasites infection in indigenous chicken. This study was conducted to determine and document the type and prevalence of haemoparasites affecting different ages and sex groups of free range indigenous chicken from two agro ecological zones: Lower highland 1 (LH1) in Embu District and Lower Midland 5 (LM5) in Mbeere District in Eastern Province, Kenya. Of the 144 birds examined, 79.2% were infected with haemoparasites, with 62.3% single and 37.7% mixed haemoparasitic infections. Plasmodium gallinaceum was the most prevalent haemoparasite (53.5%) followed by Leucocytozoon schoutedeni (52.1%) and Hemoproteus spp., (3.5%). Grower birds had a prevalence of 83.3% for haemoparasites compared to 81.3% of adults, and 72.9% of chicks (p> 0.05). Male birds had 83.3% prevalence, while female birds had 75.0% (p> 0.05). LH1 was found to have a slightly high prevalence of 81.9% compared to LM5, 76.4% (p> 0.05). Hemoproteus spp were isolated in chickens from LH1 but not from LM5. This study has documented a high prevalence of haemoparasites, hence further studies to determine the impact of infection on the health and productivity of these birds, and evaluation of cost benefit of various control strategies need to be undertaken.

Results: An average 469 new patients per year or 11 new patients per clinic visit were seen at the clinic over a two and a half year period. Females predominated (98.9%) in this series. The mean age was 34.71 years (range 1 to 96 years). The average age at menarche was 14.49 years and the mean duration of symptoms was 6.86 months. Only 2.6% of 843 patients had a positive family history of breast disease. Fibroadenoma was the commonest diagnosis made (33.2%) followed by ductal carcinoma (19.7%). Gynaecomastia was the most common lesion seen in males.

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.

The study was carried out between November 2008 and April 2009 to investigate the occurrence and pathology due to Echinostomum revolutum in free-range indigenous chickens. One hundred and fifty six (156) indigenous chickens were purchased from various farms and markets in A thorough post mortem examination was performed on each bird and the isolated worms from the ceaca, large intestines, cloaca and oviduct were identified and quantified.  Tissues were collected for histopathology, processed, examined and the severity of the lesions determined. Echinostoma revolutum was recovered in 3/156 (1.9 %) birds examined in the ceaca and large intestines but not in cloaca and oviduct. Affected birds originated from market birds in Kiambu. They caused heamorrhages and typhylo-enteritis in the affected birds. Other worms observed from these organs were Ascaridia galli, Heterakis gallinarum, Heterakis isolonche, Heterakis dispar, Subulura brumpti, Raillietina echinobothrida and Hymenolepis contaniana. The trematodes are reported in Kenya for the first time.

The study was carried out between November 2008 and April 2009 to investigate the occurrence and pathology due to Echinostomum revolutum in free-range indigenous chickens. One hundred and fifty six (156) indigenous chickens were purchased from various farms and markets in A thorough post mortem examination was performed on each bird and the isolated worms from the ceaca, large intestines, cloaca and oviduct were identified and quantified.  Tissues were collected for histopathology, processed, examined and the severity of the lesions determined. Echinostoma revolutum was recovered in 3/156 (1.9 %) birds examined in the ceaca and large intestines but not in cloaca and oviduct. Affected birds originated from market birds in Kiambu. They caused heamorrhages and typhylo-enteritis in the affected birds. Other worms observed from these organs were Ascaridia galli, Heterakis gallinarum, Heterakis isolonche, Heterakis dispar, Subulura brumpti, Raillietina echinobothrida and Hymenolepis contaniana. The trematodes are reported in Kenya for the first time.

Objective: To determine the pattern of breast disease at Kenyatta National Hospital (KNH) Study design:    Retrospective descriptive study Study setting:    Kenyatta National Hospital, a University teaching and National Referral Hospital Patients: Records of 1172 patients were reviewed. Results: An average 469 new patients per year or 11 new patients per clinic visit were seen at the clinic over a two and a half year period. Females predominated (98.9%) in this series. The mean age was 34.71 years (range 1 to 96 years). The average age at menarche was 14.49 years and the mean duration of symptoms was 6.86 months. Only 2.6% of 843 patients had a positive family history of breast disease. Fibroadenoma was the commonest diagnosis made (33.2%) followed by ductal carcinoma (19.7%). Gynaecomastia was the most common lesion seen in males. Two thirds of patients presenting with tumors had masses measuring more than 5cm.  Overall five conditions (fibroadenoma, ductal carcinoma, breast abscesses, fibrocystic disease and mastalgia) accounted for over 85% of all breast ailments. Surgery formed the main stay of care in over 80% of patients. Conclusions: The pattern of breast diseases at KNH closely mirrors those reported in other studies in the region and beyond. This study indicates that a large proportion of patients presenting with breast disease are treated initially by surgery. It may be wise to consider other alternative forms of therapy where appropriate. The Annals of African Surgery: 2008 June; Vol 2, pg 97-101.

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.
