Data relating to reproductive parameters of German shepherd bitches were collected from registered German shepherd dog (GSD) breeders with information kept over a 15-year period (1982-1997). The information obtained was verified using the East African Kennel Club records. A total of 594 bitches from 280 breeders were recorded. From these, 798 heats were observed, 594 of which were used for breeding, resulting in 3592 puppies. The mean age at puberty was 519.0 +/- 41 days. Heats occurred throughout the year, although significantly (P < 0.05) higher and lower incidences were observed in October and April respectively Pregnancy significantly (P < 0.01) increased interoestrous interval, which was 247.8 +/- 99.6 and 183 +/- 52 days among bred/pregnant and non-bred bitches respectively. Most bitches in oestrus (73.7%) were bred, and breeding was carried out throughout the year, with a distribution closely related to that of heat incidence. Subsequently, whelping occurred throughout the year, and 95.5% of the bitches that were mated whelped. A mean gestation period of 60.6 +/- 5.1 days was observed. The mean litter size was 6.4 +/- 0.4 puppies, and did not differ significantly between months. The preweaning losses were low, with 2.3% stillbirths, 0.9% culls and 11.4% mortalities.

United States International University-Africa, Nairobi, Kenya. OBJECTIVE: To investigate the prevalence and pattern of substance use among an undergraduate population in a Kenyan university. DESIGN: Cross-sectional survey, cluster sampling of classrooms, self-administered questionnaires. SETTING: Private international university in Nairobi province, Kenya. PARTICIPANTS: Five hundred fifty eight undergraduate students of both sexes, age range 16-50 and mean age (S.E) of 21.1 +/- 0.2. MAIN OUTCOME MEASURES: Self-reported use of psychoactive substances. RESULTS: Percentages of lifetime prevalence rates of commonly used substances were tobacco, 54.7%; alcohol, 84.2%; cannabis, 19.7% and inhalants, 7.2%. The corresponding "past use" and "current use" rates were relatively lower but followed the same pattern. The percentage rates were significantly higher in males than females (p < 0.005). Rates for regular use (> 20 days/month) were higher for tobacco (24.7%) than alcohol (11.5%). The lifetime prevalence rates of other drugs (heroin, cocaine, mandrax, amphetamines and LSD) were low (< 5%), while modest rates were recorded for tranquilizers (10.8%), local brews (13.6%) and cough mixtures (35.1%). Less than 20% of respondents initiated substance use in lower primary school, while more than 50% started using in upper primary and secondary school and 11% to 25% started using substances at university. CONCLUSION: Substances most commonly used by respondents studied were of the licit variety (alcohol and tobacco). The rate of use of the two substances is rather high. The use of illicit drugs seems to be growing and may soon escalate to alarming levels. The findings suggest an urgent need to gather more data, which can be used to guide formulation of health promotion and prevention programmes.

From these, 798 heats were observed, 594 of which were used for breeding, resulting in 3592 puppies. The mean age at puberty was 519.0 +/- 41 days. Heats occurred throughout the year, although significantly (P < 0.05) higher and lower incidences were observed in October and April respectively Pregnancy significantly (P < 0.01) increased interoestrous interval, which was 247.8 +/- 99.6 and 183 +/- 52 days among bred/pregnant and non-bred bitches respectively. Most bitches in oestrus (73.7%) were bred, and breeding was carried out throughout the year, with a distribution closely related to that of heat incidence. Subsequently, whelping occurred throughout the year, and 95.5% of the bitches that were mated whelped. A mean gestation period of 60.6 +/- 5.1 days was observed. The mean litter size was 6.4 +/- 0.4 puppies, and did not differ significantly between months. The preweaning losses were low, with 2.3% stillbirths, 0.9% culls and 11.4% mortalities.

United States International University-Africa, Nairobi, Kenya. OBJECTIVE: To investigate the prevalence and pattern of substance use among an undergraduate population in a Kenyan university. DESIGN: Cross-sectional survey, cluster sampling of classrooms, self-administered questionnaires. SETTING: Private international university in Nairobi province, Kenya. PARTICIPANTS: Five hundred fifty eight undergraduate students of both sexes, age range 16-50 and mean age (S.E) of 21.1 +/- 0.2. MAIN OUTCOME MEASURES: Self-reported use of psychoactive substances. RESULTS: Percentages of lifetime prevalence rates of commonly used substances were tobacco, 54.7%; alcohol, 84.2%; cannabis, 19.7% and inhalants, 7.2%. The corresponding "past use" and "current use" rates were relatively lower but followed the same pattern. The percentage rates were significantly higher in males than females (p < 0.005). Rates for regular use (> 20 days/month) were higher for tobacco (24.7%) than alcohol (11.5%). The lifetime prevalence rates of other drugs (heroin, cocaine, mandrax, amphetamines and LSD) were low (< 5%), while modest rates were recorded for tranquilizers (10.8%), local brews (13.6%) and cough mixtures (35.1%). Less than 20% of respondents initiated substance use in lower primary school, while more than 50% started using in upper primary and secondary school and 11% to 25% started using substances at university. CONCLUSION: Substances most commonly used by respondents studied were of the licit variety (alcohol and tobacco). The rate of use of the two substances is rather high. The use of illicit drugs seems to be growing and may soon escalate to alarming levels. The findings suggest an urgent need to gather more data, which can be used to guide formulation of health promotion and prevention programmes.

Data relating to reproductive parameters of German shepherd bitches were collected from registered German shepherd dog (GSD) breeders with information kept over a 15-year period (1982-1997). The information obtained was verified using the East African Kennel Club records. A total of 594 bitches from 280 breeders were recorded. From these, 798 heats were observed, 594 of which were used for breeding, resulting in 3592 puppies. The mean age at puberty was 519.0 +/- 41 days. Heats occurred throughout the year, although significantly (P < 0.05) higher and lower incidences were observed in October and April respectively Pregnancy significantly (P < 0.01) increased interoestrous interval, which was 247.8 +/- 99.6 and 183 +/- 52 days among bred/pregnant and non-bred bitches respectively. Most bitches in oestrus (73.7%) were bred, and breeding was carried out throughout the year, with a distribution closely related to that of heat incidence.

{ University of Nairobi, Kenya. OBJECTIVES: To profile and quantify the psychometric properties of the NOK (Ndetei-Othieno-Kathuku) scale against internationally used Gold-standards and benchmarks for mild psychiatric disorders and post-traumatic stress disorders and to provide a potential easy to administer culture sensitive instrument for screening and assessing those with possible psychiatric disorders for the Kenyan and similar social-cultural situations. DESIGN: Cross-Sectional quantitative study. SETTING: A psychiatric clinical consultation setting and Kyanguli Secondary School psychotrauma counselling clinical set-up. SUBJECTS: Survivors of the Nairobi USA Embassy bombing who were referred for psychiatric treatment and survivors of a fire disaster from a rural Kenyan school (Kyanguli School fire disaster) including students, parents of the diseased children and staff members. RESULTS: Positive correlation was found between the NOK and all the instruments. The highest correlations were between the NOK and the BDI and SCL-90 (r = 0.557 to 0.786). The differences between the NOK scores among the different groups were statistically significant (F ratio = 13.54 to 160.34, p < 0.01). The reliability coefficient (internal consistency) of the scale

DESIGN: Cross-sectional survey, cluster sampling of classrooms, self-administered questionnaires. SETTING: Private international university in Nairobi province, Kenya. PARTICIPANTS: Five hundred fifty eight undergraduate students of both sexes, age range 16-50 and mean age (S.E) of 21.1 +/- 0.2. MAIN OUTCOME MEASURES: Self-reported use of psychoactive substances. RESULTS: Percentages of lifetime prevalence rates of commonly used substances were tobacco, 54.7%; alcohol, 84.2%; cannabis, 19.7% and inhalants, 7.2%. The corresponding "past use" and "current use" rates were relatively lower but followed the same pattern. The percentage rates were significantly higher in males than females (p < 0.005). Rates for regular use (> 20 days/month) were higher for tobacco (24.7%) than alcohol (11.5%). The lifetime prevalence rates of other drugs (heroin, cocaine, mandrax, amphetamines and LSD) were low (< 5%), while modest rates were recorded for tranquilizers (10.8%), local brews (13.6%) and cough mixtures (35.1%). Less than 20% of respondents initiated substance use in lower primary school, while more than 50% started using in upper primary and secondary school and 11% to 25% started using substances at university. CONCLUSION: Substances most commonly used by respondents studied were of the licit variety (alcohol and tobacco). The rate of use of the two substances is rather high. The use of illicit drugs seems to be growing and may soon escalate to alarming levels. The findings suggest an urgent need to gather more data, which can be used to guide formulation of health promotion and prevention programmes.

Data relating to reproductive parameters of German shepherd bitches were collected from registered German shepherd dog (GSD) breeders with information kept over a 15-year period (1982-1997). The information obtained was verified using the East African Kennel Club records. A total of 594 bitches from 280 breeders were recorded. From these, 798 heats were observed, 594 of which were used for breeding, resulting in 3592 puppies. The mean age at puberty was 519.0 +/- 41 days. Heats occurred throughout the year, although significantly (P < 0.05) higher and lower incidences were observed in October and April respectively Pregnancy significantly (P < 0.01) increased interoestrous interval, which was 247.8 +/- 99.6 and 183 +/- 52 days among bred/pregnant and non-bred bitches respectively. Most bitches in oestrus (73.7%) were bred, and breeding was carried out throughout the year, with a distribution closely related to that of heat incidence. Subsequently, whelping occurred throughout the year, and 95.5% of the bitches that were mated whelped. A mean gestation period of 60.6 +/- 5.1 days was observed. The mean litter size was 6.4 +/- 0.4 puppies, and did not differ significantly between months. The preweaning losses were low, with 2.3% stillbirths, 0.9% culls and 11.4% mortalities.

R W Nduati. Acute Septic Arthritis As It Is Seen In Children At Kenyatta National Hospital.; 1987. Abstract

A nine-month study was done on children with acute septic arthritis admitted to the Paediatric Orthopaedic and general paediatric wards. The aims of the study were to elucidate the clinical characteristics and aetiological agents of septic arthritis in children admitted to Kenyatta National Hospital. Thirty one children were recruited into the study and of these 58% were infants and 32.3% were school age children. There was a striking male predominance in the school age children - 9:1 while male/female ratio was 1.2:1 in the
younger children. Knees and shoulders were the most frequently affected by septic arthritis and together were responsible for
71% of the septic joints. It is of interest that all the septic

shoulder joints occurred in infancy. Non-typhoidal salmonella species especially Salmonella typhimurium, Klebsiella species and Staphylococcus aureus were the most frequently isolated bacteria.

The rate of bacterial isolation was as high as 72.2% when both blood cultures and joint aspirate cultures were done. Salmonella species had 75% sensitivity to the aminoglycosides (Gentamicin,Kanamycin) and Chloramphenicol while only two thirds of the Klebsiella species were sensitive to the same antibiotics. Staphylococcus aureus isolated in this study were sensitive to Erythromycin and uniformly resistant to
Ampicillin,.Cloxacillin and Cotrimoxazole. There was full

recovery in 63.7% of the patients while 23% went home without appropriate follow-up.

The author recommends that blood and joint aspirate cultures should be done in all patients suspected to have septic arthritis. Antibiotic sensitivity testing should be done r~gularly to facilitate appropriate drug therapy. Clinicians should ensure adequate follow-up of patients following discharge from hospital.

A study of vision-related quality of life and visual acuity in Kenya.Ophthalmic Epidemiol. 2010 Jan-Feb;17(1):41-9.". In: PMID: 20100099 [PubMed - indexed for MEDLINE]. Korean Society of Crop Science and Springer; 2010. Abstract

PURPOSE: To determine possible differences in visual acuity, socio-demographic factors and vision-related Quality of Life (QoL) between people accepting and people refusing sponsored cataract surgery.

METHODS: Three hundred and fifty seven local residents with visually impairing cataract, presenting at screening sites in Kwale District, Kenya were clinically assessed and interviewed. The World Health Organization (WHO) QoL-questionnaire WHO/Prevention of Blindness and Deafness Visual Functioning Questionnaire 20 (PBD-VFQ20) was used to determine the vision-related QoL. A standardized questionnaire asked for socio-demographic data and prior cataract surgery in one eye. After interview, patients were offered free surgery. Primary outcome was the mean QoL-score between acceptors and non-acceptors. Secondary outcomes were visual acuity and socio-demographic factors and their contribution to QoL-scores and the decision on acceptance or refusal.

RESULTS: Fifty nine people (16.5%) refused and 298 accepted cataract surgery. Vision-related QoL was poorer in people accepting than in those refusing (mean score 51.54 and 43.12 respectively). People with poor visual acuity were only slightly more likely to accept surgery than people with better vision; the strongest predictors of acceptance were the QoL-score and gender. Men were twice as likely to accept compared to women. Of people who accepted surgery, 73.8% had best eye vision of 20/200 or better.

CONCLUSION: In this population, visual acuity was of limited use to predict a person's decision to accept or refuse cataract surgery. QoL-scores provide further insight into which individuals will agree to surgery and it might be useful to adapt the QoL-questions for field use. Gender inequities remain a matter of concern with men being more likely to get sight-restoring surgery.

OBJECTIVES: To estimate the prevalence of active trachoma (TF) in children aged one to nine years and potentially blinding trachoma (TT) in adults aged 15 years and older in six known trachoma-endemic districts in Kenya. DESIGN: Community based survey. SETTING: Six known trachoma endemic districts in Kenya (Samburu, Narok, West Pokot, Kajiado Baringo and Meru North). SUBJECTS: A total of 6,982 children aged one to nine years and 8,045 adults aged 15 years and older were randomly selected in a two stage random cluster sampling method: Twenty sub-locations (clusters) per district and three villages per sub-location were randomly selected. Eligible children and adults were enumerated and examined for signs of trachoma. RESULTS: Blinding trachoma was found to be a public health problem in all the surveyed districts. Active trachoma was a district wide public health problem in four districts (Samburu, Narok, West Pokot and Kajiado) and only in some of the sub-locations of the other two (Baringo and Meru North). CONCLUSIONS: There is need for district trachoma control programmes preferably using the WHO recommended SAFE strategy in all the surveyed districts. Extrapolation of these survey results to the entire country could not be justified. There is need to survey the remaining 12 suspected endemic districts in Kenya.

OBJECTIVE: To estimate the prevalence and pattern of conjuctival squamous cell carcinoma (CSCC) in patients with HIV infection. DESIGN: A hospital based cross sectional study. SETTING: Kenyatta National Hospital (KNH) and Kikuyu Eye Unit (KEU) during the period November 2003 and May 2004. SUBJECTS: Four hundred and nine HIV positive patients. RESULTS: Four hundred and nine HIV positive patients aged 25 to 53 years were screened. Male to Female ratio was 1:1. One hundred and three had conjunctival growths. Thirty two had histologically proven conjunctiva squamous cell carcinoma (CSCC). Estimated prevalence of CSCC among HIV positive patients was 7.8%. The average duration of growth of the conjunctival masses was 21.8 months. The average size of the lesions at the time of presentation was 6.6 mm. Twenty two (68.8%) patients had primary CSCC, while ten (31.2%) had recurrent lesions. The pattern of the histopathology results was: fifteen (46.9%) patients had poorly differentiated squamous cell carcinoma; nine (28%) had moderately differentiated squamous cell carcinoma; five patients (15.6%) had CIN; two patients (6.3%) had dysplasia and one patient (3.1%) had a well differentiated squamous cell carcinoma. CONCLUSIONS: Prevalence of CSCC in HIV/AIDS patients was 7.8%. Patients present late with advanced lesions. Recurrence rates from previous surgery are high. The often uncharacteristic complaints and findings on presentation complicate the clinical diagnosis. Active search for early manifestations of CSCC in HIV / AIDS patients, complete surgical excision and close follow up is necessary. Alternative treatment methods and techniques like the topical use of antimetabolites should be explored further.

CONCLUSIONS: There is need for district trachoma control programmes preferably using the WHO recommended SAFE strategy in all the surveyed districts. Extrapolation of these survey results to the entire country could not be justified. There is need to survey the remaining 12 suspected endemic districts in Kenya.

OBJECTIVES: To estimate the prevalence of active trachoma (TF) in children aged one to nine years and potentially blinding trachoma (TT) in adults aged 15 years and older in six known trachoma-endemic districts in Kenya. DESIGN: Community based survey. SETTING: Six known trachoma endemic districts in Kenya (Samburu, Narok, West Pokot, Kajiado Baringo and Meru North). SUBJECTS: A total of 6,982 children aged one to nine years and 8,045 adults aged 15 years and older were randomly selected in a two stage random cluster sampling method: Twenty sub-locations (clusters) per district and three villages per sub-location were randomly selected. Eligible children and adults were enumerated and examined for signs of trachoma. RESULTS: Blinding trachoma was found to be a public health problem in all the surveyed districts. Active trachoma was a district wide public health problem in four districts (Samburu, Narok, West Pokot and Kajiado) and only in some of the sub-locations of the other two (Baringo and Meru North). CONCLUSIONS: There is need for district trachoma control programmes preferably using the WHO recommended SAFE strategy in all the surveyed districts.

The gene Q13L coding for the Capripoxvirus group specific structural protein P32 was expressed in Escherichia coli using plasmid pGEX-2T as a fusion protein with glutathione-s-transferase and purified on glutathione sepharose affinity chromatography column. The protein was then employed for diagnosis of sheeppox, goatpox and lumpyskin disease, by a latex agglutination test (LAT) using the purified P32 antigen and guinea pig detector antiserum raised against the P32 antigen. The LAT and virus neutralization test (VNT) were used to screen one hundred livestock field sera for antibodies to Capripoxvirus, in comparison the LAT was simpler, rapid and 23% more sensitive than the VNT. In addition the LAT was found to be specific for Carpripoxvirus because it did not pick antibodies to Orthopoxvirus and Parapoxvirus. The LA test can be taken for a simple and quick diagnostic tool for primary screening of Carpripoxvirus infection and will reduce the reliance of diagnostic laboratories on tissue culture facilities. Keywords: Carpripox, latex agglutination test, attachment gene J. Trop. Microbiol. Biotechnol. Vol. 3 (2) 2007: pp. 36-43

OBJECTIVE: To estimate the prevalence and pattern of conjuctival squamous cell carcinoma (CSCC) in patients with HIV infection. DESIGN: A hospital based cross sectional study. SETTING: Kenyatta National Hospital (KNH) and Kikuyu Eye Unit (KEU) during the period November 2003 and May 2004. SUBJECTS: Four hundred and nine HIV positive patients. RESULTS: Four hundred and nine HIV positive patients aged 25 to 53 years were screened. Male to Female ratio was 1:1. One hundred and three had conjunctival growths. Thirty two had histologically proven conjunctiva squamous cell carcinoma (CSCC). Estimated prevalence of CSCC among HIV positive patients was 7.8%. The average duration of growth of the conjunctival masses was 21.8 months. The average size of the lesions at the time of presentation was 6.6 mm. Twenty two (68.8%) patients had primary CSCC, while ten (31.2%) had recurrent lesions. The pattern of the histopathology results was: fifteen (46.9%) patients had poorly differentiated squamous cell carcinoma; nine (28%) had moderately differentiated squamous cell carcinoma; five patients (15.6%) had CIN; two patients (6.3%) had dysplasia and one patient (3.1%) had a well differentiated squamous cell carcinoma. CONCLUSIONS: Prevalence of CSCC in HIV/AIDS patients was 7.8%. Patients present late with advanced lesions. Recurrence rates from previous surgery are high. The often uncharacteristic complaints and findings on presentation complicate the clinical diagnosis. Active search for early manifestations of CSCC in HIV / AIDS patients, complete surgical excision and close follow up is necessary. Alternative treatment methods and techniques like the topical use of antimetabolites should be explored further.

Studies were commenced to collect and identify the phlebotomine sandflies found in Nairobi. These studies were also aimed at determining their numbers as well as assessing the effects of seasonal changes on the sandfly population. Four trapping methods, namely, light traps, sticky traps, aspiration and human bait were employed. Eight species and one undescribed species were recorded over a period of 6 months. The identified species included Phlebotomus guggisbergi (Kirk and Lewis), P. rodhaini (Parrot), Sergentomyia adleri (Theodor), S. harveyi (Heisch, Guggisberg and Teesdale) and S. bedfordi (Newstead) and an undescribed species. Most of the sandfly species trapped showed seasonal prevalence. The seasonal variation was closely related to the weather conditions. Sandflies were found in termite mounds, animal burrows, caves and dugouts some of which were near human habitations. Termite mounds and animal burrows were the most preferred habitats.
