Department of Dental Surgery, College of Health Sciences, University of Nairobi, Kenya. Two hundred and fifty one African children aged 13-15 years were examined for specific intra- and inter-arch malocclusions and tooth loss. The children were from 6 schools randomly selected from 154 primary schools in Nairobi. Overall, 47% of the children were found to have malocclusion, the most frequently encountered anomaly being crowding. Some of the anomalies showed prevalences which differed markedly from those previously reported for American and British Caucasians of comparable age-groups. Nineteen per cent of the children had missing teeth due to caries, 5.6% due to extractions as part of orthodontic treatment and 13% due to other reasons. The mean number of permanent teeth missing due to caries was 0.2, orthodontic treatment 0.1 and due to other reasons 0.2. Almost all the teeth lost as a result of caries were molars and those due to orthodontic indications were premolars. No teeth were recorded as missing due to periodontal disease or trauma. The study indicated a need to exercise caution in trying to relate the numerical values for prevalence of malocclusions in current textbooks to the present population. The results also showed that the proportion of permanent teeth lost was small.

Department of Paediatric Dentistry and Orthodontics, Dental School, University of Nairobi, Kenya. The purpose of this study was to obtain data on the oral hygiene practices, oral hygiene status, and periodontal health among primary school children in Nairobi. The study group consisted of 513 children, 262 aged 6-8 years and 251 aged 13-15 years. The children were from 6 schools randomly selected among the 154 public primary schools in the city. The clinical examination was performed in a room with natural daylight, using the WHO (1980) criteria. Although most of the children reported brushing habits, 75% of the index tooth surfaces in the younger and 55% in the older age group had visible plaque. In both age groups about 25% of the index sites had gingivitis. Moderate amounts of calculus were recorded among the older children. Only two children had periodontal pockets greater than or equal to 4 mm. There was no statistically significant difference (p greater than 0.05) between males and females recorded with plaque and gingivitis in the younger age group. In the older group, however, a significantly higher proportion of males (p less than 0.05) were recorded with plaque and gingivitis. The oral hygiene practices and oral hygiene status were poorer among children from low than from high socioeconomic status. Provision of dental health education for children in Nairobi is recommended.

Am J Orthod Dentofacial Orthop. 1992 Sep;102(3):244-50.". In: Am J Orthod Dentofacial Orthop. 1992 Sep;102(3):244-50. Hekima III (1) 27-42; 1992. Abstract

Information related to bonding of orthodontic brackets to fluorotic teeth is scanty. The purpose of this study was to compare, in vitro, the tensile bond strength and the bond failure site of brackets bonded directly to fluorotic and nonfluorotic teeth. The etching patterns were also evaluated. The study involved 26 teeth classified as score 3 and 4, and 26 as score 0 with the Thylstrup and Fejerskov's (TF) fluorosis index. In addition to the clinical classification, difference in the concentration of fluoride in the teeth was verified by acid etching. Brackets were bonded with a composite resin after etching the enamel surface with 40% phosphoric acid for 60 seconds. Tensile bond strength was determined with an Instron testing machine. The bond failure site was assessed by the percentage of residue cement on the tooth surface after debonding and the etching pattern by SEM. The mean concentration of fluoride was 2888.5 ppm (SD 1081.7) in the fluorotic teeth and 1227.1 ppm (SD 526.3) in the nonfluorotic teeth. The mean bond strength was 7.8 N/mm2 (SD 1.47) for the fluorotic teeth and 8.6 N/mm2 (SD 2.19) for the nonfluorotic teeth. The difference between the means for bond strength was not statistically significant (p greater than 0.05). Bond failure site was primarily at the bracket-adhesive interface. The mean percentage of adhesive on the enamel surface after debonding was 70% (SD 25.90) for the fluorotic teeth and 75% (SD 24.66) for nonfluorotic teeth. The difference in the means was not statistically significant (p greater than 0.05).

The present longitudinal study was conducted on ten children from age 5-6 years to determine the post-eruptive enamel changes of fluorosed permanent incisors. The children were born and reared in an area of Kenya with a water fluoride level of 14-45 parts per million. The incisors were examined and photographed periodically from the time of eruption over a period of 2 1/2 years. It was noted that the fluorosed incisor was intact as it erupted and then it underwent a variety of changes. In some there was mechanical breakdown (pitting) of the chalky white enamel which occurred rapidly initially and then the breakdown slowed down by 2 years. In others, there was smoothening of the pitted enamel resulting in a translucent appearance. Alternatively there was some degree of patchy staining of the enamel without surface breakdown. Much of the cervical 1/3 of the enamel remained intact even in teeth with severe breakdown. In most cases, these changes were bilaterally symmetrical. The possible reasons for these changes are discussed.

Department of Paediatric Dentistry and Orthodontics, Faculty of Dental Sciences, University of Nairobi, P.O. Box 19676, Nairobi, Kenya. Although multiple supernumerary teeth without any associated syndromes are rare, their occurrence can create a variety of clinical problems such as derangement of the occlusion, prevention of eruption of permanent teeth, damage to adjacent teeth, cystic degeneration and root resorption. Hence, clinical and radiographic evaluation of patients should always be thorough in order to detect their presence. Furthermore, because the clinical management of multiple supernumerary teeth poses a great challenge to clinicians, timely, appropriate consultation and interdisciplinary approach to treatment is extremely important. We report two cases, a 14 year-old boy with eight and a 13-year-old girl with seven supernumerary teeth not associated with syndromes. In the boy, the teeth were bilaterally distributed in all quadrants in the premolar regions, and in the girl they were distributed bilaterally in the premolar regions in the mandible and bilaterally distal to the upper third molars. The clinical implications and management are discussed.

Dental School, College of Health Sciences, University of Nairobi. This paper reviews the cariological aspects of fixed orthodontic treatment and discusses the role played by topical fluorides. During fixed orthodontic treatment, carious lesions may occur in the form of white spots. These may constitute an aesthetic problem. The clinical management of white spot lesions remains unresolved. In order to prevent development of these lesions, the use of topical fluorides is advocated. The need for patient co-operation in the use of self-administered topical fluorides is critical. To reduce this critical need, the use of fluoride-releasing orthodontic cements is recommended. The literature suggests that calcium fluoride, which is the major reaction product on enamel during topical fluoride application, plays an important role in the cariostatic mechanism.

Department of Pediatric Dentistry and Orthodontics, University of Nairobi Dental School, Kenya. Data on occlusal features and the need for orthodontic treatment in Kenya is scanty. This study was carried out to determine the prevalence of malocclusion in children in Nairobi, Kenya. Nine hundred and nineteen children aged 13-15 years (468 male, 451 female) were examined. The registration method used was that described by Bjork et al. The prevalence of malocclusion was 72%. The predominant anteroposterior relationship of the dental arches was neutral occlusion (93%). Specific malocclusion traits were highest for crowding (19%), rotations (19%), posterior crossbite (10%), maxillary overjet (10%), and frontal open bite (8%). There was no statistically significant difference in the overall prevalence of malocclusion between males and females, but some occlusal traits were significantly higher in males. Although the findings indicate that the present population is not characterized by a substantial difference in the overall prevalence of malocclusion compared with other communities, some traits differed in prevalence from those reported elsewhere.

Department of Pediatric Dentistry and Orthodontics, University of Nairobi Dental School, Kenya. The need for orthodontic treatment in Kenya was previously not been investigated. This study was undertaken to assess the need for orthodontic treatment in 13- to 15-year-old children in Nairobi. The objective need was assessed in 919 children by using the Norwegian treatment need index, and the subjective need was assessed in 739 children by using a structured questionnaire. Objective treatment need was recorded in 29% and subjective need in 33% of the children. Less than 1% were allocated the 'very great need' category. Relatively more girls than boys were dissatisfied with the appearance of their teeth, and a significantly higher number of girls (P < 0.001) said they would like to have their teeth straightened. The children's perceived need for treatment correlated significantly with the treatment need index. Fixed appliances were found necessary for correcting malocclusion in 23% of the children and removable appliances in 6%. Future studies in Kenya should be directed at determining the societal perception of malocclusion, upon which treatment standards may be based.

The purpose of this study was to record the caries status in children attending public primary schools in Nairobi. The sample comprised 513 children, 262 aged 6-8 years and 251 aged 13-15 years. The children were drawn from six randomly selected schools in the city. Clinical examination was carried out in a room with natural daylight, using the WHO (1977) criteria. Fifty-four per cent of the 6- to 8-year-olds and 50% of the 13- to 15-year-olds were caries-free. The mean dmft in the 6- to 8-year-olds was 1.7, and the mean dmfs was 3.5. The mean DMFT in the 13- to 15-year-olds was 1.8, and the mean DMFS was 2.9. The d- and D-components dominated and were mainly located in the occlusal surfaces. The f-component of the dmft and the F-component of the DMFT comprised 1% and 10%, respectively. There was no statistically significant difference (p > 0.05) in the prevalence of caries between males and females in the younger age group. In the older age group, however, females had a higher (p < 0.05) prevalence than males. In general, the study showed a low caries prevalence in Nairobi children.

Department of Pediatric Dentistry and Orthodontics, Dental School, University of Nairobi, Kenya. The purpose of this study was to assess the prevalence and severity of dental fluorosis in 513 primary school children in Nairobi. The clinical examination was performed in a room with natural daylight using Thylstrup & Fejerskov's index (TFI). Overall, 18% of 6-8-yr-olds had dental fluorosis in the primary dentition and 76% of 13-15-yr-olds in the permanent dentition. There was no significant sex difference (P > 0.05) in either the prevalence or the severity of fluorosis. In children with mixed dentition, the prevalence and severity of fluorosis was higher in the permanent teeth. In the permanent dentition, no clear difference was demonstrable in the severity between the anterior and the posterior teeth. The degree of fluorosis in most of the children in the area served with river water (0.2-0.4 ppm F-) was of a very mild form. However, in the area served with borehole waters, 48% of the children and 40% of the teeth were found to have TFI scores > or = 5. Measures to reduce dental fluorosis are necessary in the latter area.

Department of Dental Surgery, University of Nairobi, Kenya. The present longitudinal study was conducted on ten children from age 5-6 years to determine the post-eruptive enamel changes of fluorosed permanent incisors. The children were born and reared in an area of Kenya with a water fluoride level of 14-45 parts per million. The incisors were examined and photographed periodically from the time of eruption over a period of 2 1/2 years. It was noted that the fluorosed incisor was intact as it erupted and then it underwent a variety of changes. In some there was mechanical breakdown (pitting) of the chalky white enamel which occurred rapidly initially and then the breakdown slowed down by 2 years. In others, there was smoothening of the pitted enamel resulting in a translucent appearance. Alternatively there was some degree of patchy staining of the enamel without surface breakdown. Much of the cervical 1/3 of the enamel remained intact even in teeth with severe breakdown. In most cases, these changes were bilaterally symmetrical. The possible reasons for these changes are discussed.

OBJECTIVE: To determine the dietary patterns and nutritional status of pre-school children in Nairobi, Kenya. DESIGN: A cross-sectional study. SETTING: Pre-schools in Nairobi, Kenya. SUBJECTS: Three hundred and four pre-school children (149 males and 155 females) aged three to five years were assessed. RESULTS: About 96% of the children had been breastfed 46.7% of them for 12-24 months (46.7%), and the mean breastfeeding duration was 20.17 months. The most commonly consumed foods on a daily basis were fruits, vegetables bread, ugali, porridge and milk. The level of malnutrition was low with underweight at 16% stunting 4.3% and wasting 1.0%. The factors that positively correlated with child nutritional status were the age of the mother and father. CONCLUSIONS: The children were consuming a variety of foods both at home and in school, and this together with the high literacy levels the parents/guardians could have contributed towards the good nutritional status.

Kiambu District Hospital, Kenya. OBJECTIVE: To assess the occurrence of hypodontia (except 3rd molars) in a population of orthodontic patients. DESIGN: A retrospective case study. SETTING: Private orthodontic practice in Nairobi PATIENTS: Six hundred and fifteen orthodontic patients aged eight to fifteen years. RESULTS: Hypodontia occurred in 39 children (6.3%). The missing teeth were observed in 24 males (7.2%) and 15 females (5.3%). Of the children with hypodontia, about 80% lacked one or two teeth, 54% had hypodontia involving anterior teeth, 18% lacked single posterior teeth and 8% had two or more teeth missing in the same quadrant. The highest recorded number of missing teeth in any one individual was seven. The most frequently missing teeth were mandibular 2nd premolars (30%), maxillary 2nd premolars (24%) and maxillary lateral incisors (22%) in that order. CONCLUSIONS: Our data for hypodontia were within the wide range reported in the literature. The finding of patients with hypodontia involving the anterior teeth and others missing more than two teeth in the same quadrant was an indication of a great need for orthodontic treatment. The present findings reiterate the neeed for a thorough radiographic evaluation of patients prior to removal of permanent teeth for orthodontic reasons.

Although a relationship between Lapiat and post-Lapita ceramic traditions has long been suspected, a systematic and detailed examination of the similarities and differences has not been previously made. An important first step is to determine the nature of change from one to the other by examining pottery from sites which have the full ceramic sequence. My analyses of the assemblages from Manus and New Island demonstrate continuity between the two traditions.

The periodontal health status of diabetic patients and the association between periodontal disease and treatment mode, age and duration of diabetes were investigated in 86 dentulous men and women aged between 20 years and 69 years. 43 were diabetics regularly controlled at Kenyatta National Hospital Diabetic Clinic and 43 were non-diabetics attending medical outpatient clinic at the same hospital for minor ailments. Diabetic patients were found to have significant severer levels of periodontal disease than the non-diabetics. The difference persisted with increasing age.

East African Medical Journal 67:No 1(1990).". In: East African Medical Journal 67:No 1. Dar-es-salaam University Press (DUP) in 1996.; 1990. Abstract
The present longitudinal study was conducted on ten children from age 5-6 years to determine the post-eruptive enamel changes of fluorosed permanent incisors. The children were born and reared in an area of Kenya with a water fluoride level of 14-45 parts per million. The incisors were examined and photographed periodically from the time of eruption over a period of 2 1/2 years. It was noted that the fluorosed incisor was intact as it erupted and then it underwent a variety of changes. In some there was mechanical breakdown (pitting) of the chalky white enamel which occurred rapidly initially and then the breakdown slowed down by 2 years. In others, there was smoothening of the pitted enamel resulting in a translucent appearance. Alternatively there was some degree of patchy staining of the enamel without surface breakdown. Much of the cervical 1/3 of the enamel remained intact even in teeth with severe breakdown. In most cases, these changes were bilaterally symmetrical. The possible reasons for these changes are discussed.

Osteosarcoma (OS) is a highly malignant tumour and is the most common primary neoplasm of bone; although rare, especially in the maxillofacial skeleton. This article presents 14 Kenyan cases of OS of the maxillofacial bones seen between January 1991 and July 1997: 11 in the mandible, two in the maxilla and one in the right zygomatic arch. Patients ranged in age from one week to 50 years (Mean = 29.7), with an equal gender distribution. While pain and rapid swelling were the commonest clinical features, the radiographic and histopathological characteristics were as varied as has been described elsewhere. Generally, effective management of most of the cases was poor due to late presentation for treatment.

OBJECTIVE: To determine the dietary patterns and nutritional status of pre-school children in Nairobi, Kenya. DESIGN: A cross-sectional study. SETTING: Pre-schools in Nairobi, Kenya. SUBJECTS: Three hundred and four pre-school children (149 males and 155 females) aged three to five years were assessed. RESULTS: About 96% of the children had been breastfed 46.7% of them for 12-24 months (46.7%), and the mean breastfeeding duration was 20.17 months. The most commonly consumed foods on a daily basis were fruits, vegetables bread, ugali, porridge and milk. The level of malnutrition was low with underweight at 16% stunting 4.3% and wasting 1.0%. The factors that positively correlated with child nutritional status were the age of the mother and father. CONCLUSIONS: The children were consuming a variety of foods both at home and in school, and this together with the high literacy levels the parents/guardians could have contributed towards the good nutritional status.

Ethnopharmacological relevance: Traditional medicines play an important role in the management of chronically painful and debilitating joint conditions, particularly in the rural Africa. However, their potential use as sources of medicines has not been fully exploited. The present study was carried to find the medicinal plants traditionally used to manage chronic joint pains in Machakos and Makueni counties in Kenya. Materials and methods: To obtain this ethnobotanical information, 30 consenting traditional herbal med-ical practitioners were interviewed exclusively on medicinal plant use in the management of chronic joint pains, in a pre-planned workshop. Results and discussion: In this survey, a total of 37 plants belonging to 32 genera and 23 families were cited as being important for treatment of chronic joint pains. The most commonly cited plant species were Pavetta crassipes K. Schum, Strychnos henningsii Gilg., Carissa spinarum L., Fagaropsis hildebrandtii (Engl.) Milve-Redh. and Zanthoxylum chalybeum Engl. Acacia mellifera (Vahl) Benth., Amaranthus albus L., Balanites glabra Mildbr. & Schltr., Grewia fallax K. Schum., Lactuca capensis, Launaea cornuta (Oliv. & Hiern) O.

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.

To determine the prevalence of sucking habits and its association with anterior open bite, posterior cross-bite and transverse dimensions of the Jaws In 3-5-year-olds in Nairobi. Design: A cross-sectional study. Setting: Nairobi, Kenya. Subjects: Three hundred and four children aged 3-5 years (155 boys and 149 girls). Results: The prevalence of digit suckers was 15.8%, nd pacifier users 1.0%. Those with anterior open bite constituted 7.6%. The average intercanine archwidth between 53-63 was 3d.8mm and between 73-83 was 25.4mm. A statistically significant correlation (Pearson!)was observed between digit-sucking and anterior open bite (P<0.01). Concluslon: The present study forms a baseline for future trends in sucking habits among children in Nairobi, Kenya. Low prevalence of sucking habits was found. The average difference between the upper and lower intercanine arch widths was relatively high and prevalence of postenor cross-blte was low. A significant correlation was observed between anterior open bite and digit sucking. The need for orthodontic treatment due to sucking habit was low among children in Nairobi.

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

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.

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.

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

isolated from preterm neonates during the outbreak of gastroenteritis in hospital in Nairobi, Kenya, were resistance to trimethoprin-sulfathoxaxole, Chloramphenicol, oxytetracycline and ampicilin, but only a few strains were resistant to cefazolin, cefamandole, cefataximine, amikacin and nalidixic acid. Fourteen different antimicrobial resistance patterns were observed in the 229 strains of E.coli analyzed. Eighty-two percent of the EPEC strains belonged to two resistance patterns. There was no consistent relationship between palsmid profile group and antimicrobial resistance pattern, although one resistance pattern was more frequently observed in EAF-positive strins belonging to the dominant plasmid profile group. Nine percent of the EPEC strins were resistant to gentamicin compared to 37% in the non-EPEC group. No correlation was observed between administration of gentamicin and percentage of resistant strains isolated. None of the nine neonates receiving gentamicin died during the outbreak. Gentamicin resistance was observed in E.coli strains from six out of these nine neonates. Five out of fourteen neonates who received other antimicrobials, or no antibiotic at all, died.

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 study that devised a modified method of reporting antibiotic sensitivity results was undertaken. Enterobacteriaceae and Gram positive cocci were tested for drug sensitivity by a disc diffusion method. Zones of bacterial growth inhibition were measured, dividing the isolates into four groups: the highly sensitive, the moderately sensitive, the slightly sensitive and the resistant ones. The slightly sensitive isolates were taken as indicators of antibiotic resistance acquisition. By that system, when more than 50% of the isolates fell into the slightly and resistant groups, that meant that the antibiotic concerned would be discontinued for some time until the bacteria reverted to being moderately sensitive. The study also provided a method of making antibiotic discs from local blotting papers, and a sample of a form on which antibiotic sensitivity results could be recorded was presented. The method is considered to be easy and very appropriate for developing countries in detecting gradual and abrupt acquisition of antibiotic resistance by bacteria.

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

OBJECTIVE–To determine the efficacy of the nonoxynol 9 contraceptive sponge in preventing sexual acquisition of the human immunodeficiency virus (HIV). DESIGN–Prospective, randomized placebo-controlled trial. SETTING–Research clinic for prostitutes in Nairobi, Kenya. PATIENTS AND INTERVENTIONS–One hundred thirty-eight HIV-seronegative women were enrolled, of whom 74 were assigned to nonoxynol 9 sponge use and 64 to placebo use. These two groups did not significantly differ with respect to demographic characteristics, sexual practices, or prevalence of genital infections at enrollment, except for a lower number of sex partners per week and a higher initial prevalence of genital ulcers among women assigned to nonoxynol 9 sponge use. Among the 116 women who returned for follow-up, the mean durations of follow-up were 14 and 17 months for the two groups, respectively. MAIN OUTCOME MEASURE–HIV seroconversion. RESULTS–Nonoxynol 9 sponge use was associated with an increased frequency of genital ulcers (relative risk [RR], 3.3; P less than .0001) and vulvitis (RR, 3.3; P less than .0001) and a reduced risk of gonococcal cervicitis (RR, 0.4; P less than .0001). Twenty-seven (45%) of 60 women in the nonoxynol 9 sponge group and 20 (36%) of 56 women in the placebo group developed HIV antibodies. The hazard ratio for the association between nonoxynol 9 sponge use and HIV seroconversion was 1.7 (95% confidence interval [CI], 0.9 to 3.0). Using multivariate analysis to control for the presence of genital ulcers at enrollment, the adjusted hazard ratio for the association between nonoxynol 9 sponge use and seroconversion was 1.6 (95% CI, 0.8 to 2.8). CONCLUSIONS–Genital ulcers and vulvitis occurred with increased frequency in nonoxynol 9 sponge users. We were unable to demonstrate that nonoxynol 9 sponge use was effective in reducing the risk of HIV infection among highly exposed women.

In this study five aqueous extracts; Bidens pilosa, Strychnos henningsii, Aspilia pluriseta, Catha edulis and Erythrina abyssinica were screened for anti-diabetic activity and their in vivo safety evaluated. The anti-diabetic activity was assessed by intraperitoneally injecting varying doses of aqueous extracts of the five plants into alloxanised mice. Toxicity was determined by injecting normal mice with 450mg of the plant extract / kg body weight and observing the effects of the extracts on histology of various organs. All the extracts showed hypoglycaemic activity. At high doses, some plants proved to be highly toxic, mildly toxic and others were safe. This study has established that the five bioactive plants can be safely used in the management of diabetes.

Conventional drug therapy though effective in the management of diabetes mellitus is expensive and has toxic side effects. Herbal medicine would thus provide alternative therapy if effective and less toxic. This paper reviews the use of various antidiabetic plants in management of diabetes mellitus. Their documented modes of actions along with in vivo are also discussed. Keyword: Herbal medicine, Diabetes mellitus, Antidiabetic plants, Toxic side effects.

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.

East African Medical Journal. 74(8):, 1997.". In: East African Medical Journal. 74(8):, 1997. University of Nairobi.; 1997. Abstract

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.

Treatment of hyperkalaemia by altering the transcellur gradient in patients with renal failure: effect of various therapeutic approaches East African Medical Journal, 73(8): 503 -504; 1997.". In: East African Medical Journal, 73(8): 503 -504; 1997. University of Nairobi.; 1997. Abstract
Ten patients with acute and 60 with chronic renal failure (both groups having hyperkalaemia), were managed at Kenyatta National Hospital in the medical wards and Renal Unit between August, 1995 and January, 1996. They were divided into seven different treatment groups, each consisting of ten patients. Treatment A glucose 25g i.v. with insulin 10 units i.v., treatment B 50 mmol of 8.4% sodium bicarbonate infusion, treatment C 0.5mg of salbutamol i.v. in 50mls 5% dextrose, treatment D was a combination of treatments A and B, treatment E was a combination of treatment B and C, treatment F was a combination of treatments A and C while treatment G was a combination of treatments A and B and C. Serum potassium was measured, 30 minutes, 1 hour, 2 hours, 4 hours and 8 hours after treatment. Plasma glucose concentration was measured before treatment was given and 1 hour after in all patients. Electrocardiography was done before treatment on all patients and repeated 30 minutes and 1 hour after treatment for the patients with hyperkalaemic changes on the initial recording. All treatment modalities had satisfactory potassium lowering effects. Of the single therapeutic approaches, treatment A and C were equieffective, but better than treatment B (P < 0.001). Amongst the two regimen combinations, treatment D and F were more efficacious than treatment E and all the single therapeutic approaches (P < 0.001). Treatment G was the most efficacious in lowering serum potassium in this study. All treatment modalities had maximum serum potassium lowering effect at 1-2 hours. A fall in plasma glucose concentration was a notable feature of treatments A and D, but significant hypoglycaemia occurred in 20% of patients receiving treatment A and in none on treatment D. The ECG changes of hyperkalaemia did not correlate with serum potassium levels. The normalisation of hyperkalaemic ECG alteration occurred within the first 30 minutes after treatment. In conclusion, combination therapies for hyperkalaemia appear to be more efficacious than single therapeutic approaches. Inclusion of salbutamol seems to protect against insulin induced hypoglycaemia. The maximum potassium lowering effect is observed 1-2 hours of administration of either agents. The potassium reducing effect remains significant compared to baseline values even after 8 hours. If dialysis cannot be instituted early enough it seems reasonable to repeat treatment every 4-6 hours to sustain the effect. Repeated administration of glucose with insulin may not be safe because of the hypoglycaemic effect. Other single and combination therapies can theoretically be repeated regularly until dialysis is initiated although this requires further clinical evaluation.

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.

OBJECTIVES: To determine the histology of the prostate in prostatectomy done for benign prostatic hypertrology (BPH), and prostate needle biopsy done for raised prostatic specific antigen (PSA). DESIGN: A retrospective study. SETTINGS: Nairobi Hospital, Kenyatta National Hospital and Upper Hill Medical Centre. SUBJECTS: The records of all the patients who had prostatectomy for BPH or trans-rectal needle biopsy of the prostate for raised prostatic specific antigen by the author and whose histology was determined at the Nairobi Hospital between May 2004 and December 2006. RESULTS: A total of 108 specimens from 108 patients were sent to the laboratory. The ages of the patients ranged from 48 years to 83 years with a mean of 71.3 years. Of the 108 specimens submitted 82 were benign prostatic hypertrophy and 26 were carcinoma of the prostate. Out of 78 prostatectomy specimens ten (12.8%) had prostate cancer. In the needle biopsy group 16 out of 30 (53%) had prostate cancer. In total there were 82 (76%) patients with histology of benign prostate enlargement and 26 (24%) with histology of prostate cancer. CONCLUSION: Prostate cancer is a common disease in Kenya and a lot of it is important cancer as it will progress and cause death. In this poor resource setting it is possible to make diagnosis of prostate cancer even in the absence of transrectal ultrasound (TRUS) to help biopsy the prostate. The higher the prostatic specific antigen in asymptomatic patients the higher the yield of prostate cancer on biopsy of the prostate.

OBJECTIVE: To compare clean intermittent self-catheterisation and urethral dilatation with sounds in the management of recurrent urethral strictures. Design: A prospective randomised control trial between repeated urethral dilatation with sounds and use of clean intermittent self-catheterisation in the management of recurrent urethral strictures. SETTING: Kenyatta National Hospital, urology clinics. SUBJECTS: Forty nine patients with recurrent urethral strictures were randomised between clean intermittent catheterisation (CISC) and urethral dilatation with sounds. RESULTS: The urinary flow rates were better in patients on the CISC arm compared to the dilatation arm. Seventy three percent of patients having clutton sounds dilatation developed urinary tract infections compared to 25% of those on CISC. The patients in the CISC arm had a uniformly higher quality of life score than those having sounds dilatation of the urethra. CONCLUSION: Clean intermittent self-catheterisation is an effective and safe way of managing recurrent urethral strictures. It is a better method than repeated clutton sounds dilatation.

OBJECTIVE: To carry out a review of the management of early (clinically localised) prostate cancer. DATA SOURCE: Review of all published literature on the management of early prostate cancer was carried out through medline and index medicus searches. DATA SELECTION: Published data of the management of early prostate cancer over the last three decades were included in the review. DATA EXTRACTION: Abstracts of articles identified were assessed, read and analysed to determine their relevance to the title under review. DATA SYNTHESIS: After establishing relevance from the abstract, the entire paper was read, and the significant points included in the review. CONCLUSION: Greater number of men are currently being diagnosed with early prostate cancer. This is due to widespread use of Prostate Specific Antigen (PSA) screening available worldwide. Radical treatment including radical prostatectomy and radical radiation therapy have proven curative value for a significant number of men with localised disease. Survival outcomes indicate that radical prostatectomy offers more reliable cure than radiation therapy for clinically localised disease. Immediate treatment related morbidity of radical prostatectomy and radiation therapy is currently quite low. Both treatment methods have similar impact on erectile function and continence. Rectal complications are however unique to radiation therapy. Surgical and radiation therapy delivery techniques should be further improved to reduce treatment related morbidity and quality of life outcomes.

BACKGROUND: Open simple prostatectomy has long been associated with large blood losses; hence allogeneic blood transfusion in this procedure is a standard practice world over. A review of literature suggests significant association between perioperative blood loss accompanying open simple prostatectomy and certain patient factors. The shortage of blood and blood products in our blood transfusion centres as well as the alarming risks of transfusion reactions and disease dissemination demanded a review of these factors with the aim of reducing morbidity associated with peri-operative blood loss and blood transfusion. OBJECTIVES: To assess blood loss, determine blood transfusion rate, and define some of the factors associated with peri-operative blood loss and blood transfusion in open simple prostatectomy. DESIGN : A prospective cohort study. SETTINGS: The urology units of Kenyatta National Hospital, Kenya. RESULTS: Ninety five patients who underwent open simple prostatectomy for benign prostatic hyperplasia were enrolled into the study. Their median age was 70 years (Range 50 to 97). The mean decrease in haemoglobin concentration, which was the main indicator of peri-operative blood loss, was 2.1 g/dl (+/- 1.4). The peri-operative blood transfusion rate was 36.8 %. Twenty four (68.6%) of the patients who received either one or two units of blood had a pre-operative haemoglobin level above 13.5g/ dl and a post-operative haemoglobin level above 11.5 g/dl, while 11 (31.4%) had severe peri-operative bleeding, that necessitated immediate surgical re-intervention. A total of 68 units of blood was transfused, 42 (61.8%) allogeneic and 26 (38.2%) autollogous blood. The post-operative median hospitalisation time was eight days (Range 4 to 35). There were two (2.1%) post-operative deaths and both patients had intractable intra- and post-operative bleeding, massive blood transfusion and disseminated intravascular coagulopathy. The factors that were significantly associated with peri-operative blood loss and blood transfusion in open simple prostatectomy were patient's aged above 70 years, pre-operative use of acetylsalicylate or warfarin sodium, pre-operative systolic blood pressure above 140 mmHg, general anaesthesia, Freyer's (transvesical) technique and the weight of resected prostatic tissue above 70 grams. CONCLUSION: Open simple prostatectomy performed under spinal anaesthesia using Millin's (retropubic) technique is associated with minimal blood loss. The perioperative blood transfusion rate was 36.8%.

Cities around the world are currently facing considerable pressure to cope with infrastructure provision amidst rapid urban development and economic growth. Kenya is also facing an
increasing growth of informal settlements in her urban centres. As rapid urbanization takes its toll, so has the development and growth of slums. More than 34% of Kenya‟s total population lives in urban areas and of this, more than 71% is confined in informal settlements (UN-Habitat, 2009).
This paper presents the result of study to assess the effects of the change in land use in two sub-catchments, in an urban area close to the Nairobi Central Business District (NCBD). The paper compares the change in land use of two regions in Nairobi, Kenya that are slowly changing due to the fast growing population and economy, on urban runoff.

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

Towers are typical structures that can be found in many urban and rural landscapes the world over. From their basic design, they are usually exposed to severe environmental loads. It is therefore prudent to carry out periodic maintenance that includes checking that they are correctly aligned. This paper describes a method that was used for the re-alignment of a guyed tower in Limuru, Kenya. Angular and distance observations, made from two observation points detected a vertical misalignment that was larger than the acceptable tolerance of l/400. An iterative re-alignment procedure was then applied, resulting in an acceptable final misalignment of 1 / 520.

The stability of adrenaline ophthalmic solutions, at pH 5.8 and 7.4, to sterilization and storage conditions has been studied. Solutions sterilized by filtration or heating at 98 degrees C for 30 min showed no detectable degradation at either pH value, whilst sterilization at higher temperatures resulted in losses of up to 30%. Total degradation increased with increasing sterilization temperature at both pH values.

Seventeen cows of various breeds with varying degrees of severity of advanced ocular squamous cell carcinoma were treated by radical surgery, which included enucleation and extirpation of the surrounding ocular muscles and tissues. The degree of severity and the extent of the carcinoma lesion was correlated with the outcome of treatment for each case. It was observed that: 1. eyeball involvement, 2. ulceration and subsequent infection of carcinoma lesion involving the eyelids and 3. involvement of the regional lymphnodes especially the parotid , are some of the main factors that could be used to draw prognosis of such cases. Although the initial surgery may not be costly, the overall cost of managing postoperative complications is prohibitive and results to vast economic losses that should not be ignored.

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.

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

In: issueProceedings of the 5th Biennial Scientific conference, Faculty of Veterinary Medicine, September 6th . University of Nairobi; 1991. Abstract
The healing of forty full-thickness skin wounds in the distal parts of the limbs was evaluated in ten experimental calves, and observations were also made in similar wounds of nine clinical cases of cattle. All the wounds were distal to the hock and the carpus. Those in the clinical cases were mainly punctures or small laceration wounds. Septic fetlock arthritis, growth of exuberant granulation tissue, bone periostitis, tendon involvement, cellulitis, necrosis and loss of skin were the ensuing complications in the healing process of these wounds. In some cases, large blood vessels were exposed after skin loss, predisposing them to the risk of rupture and blood loss. These complications were observed to negatively influence the prognosis of wounds of the distal parts of the limbs and grossly affected the performance of eh animal as a whole. Proper management of these wounds to avoid the complications and improve the prognosis included shaving liberally round the wounds, thorough wound cleansing, topical antisepsis, dressing and bandaging to protect and immobilize the wound area and also included a course of systemic antibiotics.

In: Faculty of Veterinary Medicine Biennial Conference. 2004 Kabete Nairobi. University of Nairobi; 2006. Abstract
Trauma and surgeries are common causes of wounds that require proper management to prevent complications, economic losses, pain and suffering, death or euthanasia of the affected animals. A retrospective study of 243 wounds in cattle, sheep and goats treated between 1981 and 2006 is described. It describes practical clinical methods of categorizing and correlating wounds based on their management, complications, and prediction of prognosis. Location of a wound in the body is one of the most important factors that determine the mode of management, possible complications and anticipated outcome. Approximately 22% of the wounds were located on the ventral abdomen and thoracic regions and these healed rapidly due to good drainage of exudates. Periarticular and articular wounds constituted 17.3% and required protective and supportive bandages to prevent contamination and minimize movement. Wounds in areas prone to gross contamination constituted 14.3%, took long to heal and had a high incidence of suture dehiscence. The type of wound meant the state in which it was, while the level of tissues involved determined depth. About 46.1% of wounds involved areas with scarcity of tissue and healed slowly, while sepsis and abscessation formed 39.2% of the wounds and healed after prolonged treatment. Wounds involving dense muscular tissue were 23.6% and these healed within 3 weeks of treatment, but skin-deep wounds made 6.7% and healed within 2 weeks. Those involving the bone were 4.5% and took an average of 16 weeks to heal. Bites and gangrenous wounds were unmanageable and frequently resulted in high patient mortality, while partially granulating wounds healed rapidly. Wounds penetrating to any body cavity were best managed closed rather than open. Effective wound management-entailed debridement of deep-seated necrotic tissue, removal of foreign materials or special surgery to enhance drainage. The complicating factors included presence of subcutaneous emphysema, oedema, sepsis, foreign bodies, maggots and abscesses. Location, type and depth of wounds are therefore useful factors for categorizing wounds and these factors influence management and prognostic outcomes.

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.

Seventeen cows of various breeds with varying degrees of severity of advanced ocular squamous cell carcinoma were treated by radical surgery, which included enucleation and extirpation of the surrounding ocular muscles and tissues. The degree of severity and the extent of the carcinoma lesion was correlated with the outcome of treatment for each case. It was observed that: 1. eyeball involvement, 2. ulceration and subsequent infection of carcinoma lesion involving the eyelids and 3. involvement of the regional lymphnodes especially the parotid , are some of the main factors that could be used to draw prognosis of such cases. Although the initial surgery may not be costly, the overall cost of managing postoperative complications is prohibitive and results to vast economic losses that should not be ignored.

Open wound healing following dehorning using a wire saw was observed in 25 cattle aged between 1 and 5 years. Initially, there was a marked thickening of the scab over the wound as a ridge near the skin margin. A pale yellow to pink membrane then developed from the sides of the frontal sinus opening. Granulation tissue formed to fill the frontal sinus opening before healing by epithelization, followed by wound contraction. In some animals a bony horn stump projecting about 2-3 mm above the wound surface appeared which underwent osteosis; the dead bone gradually loosened and fell off during the healing process; histological sections revealed the presence of numerous osteoclasts lining the bone spicules. The presence of the frontal sinus and the stump of the horn processes left after dehorning are factors that make the healing of an open dehorning wound unique compared with other wounds

Seventeen cows of various breeds with varying degrees of severity of advanced ocular squamous cell carcinoma were treated by radical surgery, which included enucleation and extirpation of the surrounding ocular muscles and tissues. The degree of severity and the extent of the carcinoma lesion was correlated with the outcome of treatment for each case. It was observed that: 1. eyeball involvement, 2. ulceration and subsequent infection of carcinoma lesion involving the eyelids and 3. involvement of the regional lymphnodes especially the parotid , are some of the main factors that could be used to draw prognosis of such cases. Although the initial surgery may not be costly, the overall cost of managing postoperative complications is prohibitive and results to vast economic losses that should not be ignored.

The healing of forty full-thickness skin wounds in the distal parts of the limbs was evaluated in ten experimental calves, and observations were also made in similar wounds of nine clinical cases of cattle. All the wounds were distal to the hock and the carpus. Those in the clinical cases were mainly punctures or small laceration wounds. Septic fetlock arthritis, growth of exuberant granulation tissue, bone periostitis, tendon involvement, cellulitis, necrosis and loss of skin were the ensuing complications in the healing process of these wounds. In some cases, large blood vessels were exposed after skin loss, predisposing them to the risk of rupture and blood loss. These complications were observed to negatively influence the prognosis of wounds of the distal parts of the limbs and grossly affected the performance of eh animal as a whole. Proper management of these wounds to avoid the complications and improve the prognosis included shaving liberally round the wounds, thorough wound cleansing, topical antisepsis, dressing and bandaging to protect and immobilize the wound area and also included a course of systemic antibiotics.

OBJECTIVE: The role of Biophysical Profile Score and resistive index of the umbilical artery for monitoring pre-eclampsia patients. DESIGN: Descriptive prospective study. SETTING: Kenyatta National Hospital and Mater Hospital, Nairobi, Kenya. SUBJECTS: One hundred and ten cases during a three month period. RESULTS: Normal biophysical profile scores were found in 93 (84.5%), and 17 (17.5%) cases had abnormal scores ranging from mild to severe foetal distress. Resistive index of umbilical artery (RI-UA) were normal in 72 (66.1%) and high resistive index accounted for 33.9%. Intra-Uterine Growth Restriction (IUGR) was a prominent finding accounting for 30.5%. A positive relationship was shown to exist between IUGR and RI-UA and also with severity of hypertension with P-values < 0.05. Resistive index of umbilical artery was positively related to the duration of illness confirming its dependence on chronicity (P = 0.004). Resistive index of umbilical artery proved to be an earlier indicator of foetal compromise before any foetal distress becomes obvious. CONCLUSION: Regular obstetrical ultra sound foetal surveillance in pre-eclampsia patients is important for foetal wellbeing. Doppler evaluation of high risk patients is more sensitive test than the biophysical profile score. PMID: 16771106 [PubMed - indexed for MEDLINE]

The haemolymph of the tsetse fly, Glossina morsitans morsitans, contains a high (lipophorin) and a low molecular weight protein of high densities, 1.11 and 1.29 g/ml, respectively. The purification of the proteins was achieved by a combination of density gradient ultracentrifugation and reported gel permeation chromatography. The lipophorin is of high molecular weight (M(r) integral of 600,000) and consists of two apoproteins, apolipophorin I (M(r) integral of 250,000) and apolipophorin II (M(r) integral of 80,000) both of which are glycosylated. Lipophorin also has a pI of 6.1. However, electrophoresis under non-denaturing and denaturing conditions showed the low molecular weight protein to be a single polypeptide chain (M(r) integral of 23,000). Amino acid analysis revealed a relatively high content of the acidic amino acids as well as serine and glycine. The protein contained lipids as shown by Sudan Black staining but was unglycosylated. Using rabbit antiserum against the isolated protein in immunodiffusion and immunoblotting experiments, no cross-reactivity was detected with haemolymph samples from insects representing six orders. In conclusion, the finding of lipophorin suggests that, although flies primarily utilize proline for their energy needs, there is an active transport mechanism for the supply of lipid requirements. However, the results for the low molecular weight protein indicate that the protein is unique to Glossina, suggesting that it may have an important role in the physiology of this insect and is therefore a significant target for vector management.

Midgut homogenates prepared from Glossina morsitans morsitans, that had previously been fed on different host blood samples, were tested for their abilities to transform bloodstream Trypanosoma brucei into procyclic (midgut) forms in vitro. Compared to rat and goat blood samples, eland blood had the least capacity to support trypanosome transformation, whereas buffalo blood showed intermediate capacity. Fractionation of rat blood showed the importance of the cellular portion since both rat and eland red blood cells (RBCs) supported the process. Virtually no transformation was observed in rat and eland plasma or serum fractions. Suspending rat blood cells in eland plasma led to a reduction in parasite transformation rates. Further experiments showed that the RBC membranes were also capable of supporting the process. These results clearly show the important role played by blood, especially the red blood cells, in the transformation of bloodstream trypanosomes. In addition, the low transformation rates observed in eland blood is due to an inhibitory factor(s) present in the plasma fraction.

1. Larval development in Glossina species occurs in utero with the mature third instar larva being deposited after a developmental period of 7 days. 2. In this study, the patterns of cuticular protein synthesis during larval development were analysed by two-dimensional gel electrophoresis. 3. From the results, four types of cuticle proteins were identified: those specific to larval, pupal and adult cuticles, and others common to all the stages. 4. Few cuticular proteins were synthesized between the first and second larval instars. By the third larval instar (two days before larviposition), a large number of proteins (Mr < or = 30 kDa) were induced. These proteins persisted up to the brown pupal stage and showed a rapid decline thereafter. Most of the proteins with molecular weights Mr < or = 30 kDa were undetectable at apolysis (5 days after larviposition). 5. By day 15 of the pupal stage, the number of cuticle proteins was very small. The protein profile during the pupal stages remained relatively constant. This was probably due to the fact that the pupal cuticle does not provide any protection since it is itself enclosed at all times within the protective puparium.

In: Proceedings of the 11th Annual Medical Scientific Conference, Nairobi, Kenya. East African Medical Journal; 1990. Abstract
Lipophorin was isolated from the haemolymph of adult tsetse fly, Glossina morsitans morsitans, by ultracentrifugation in a potassium bromide density gradient. 2. The tsetse fly lipophorin (Mr congruent to 600,000) has a density of congruent to 1.11 g/ml and consists of two apoproteins, apolipophorin-I (apoLp-I, Mr congruent to 250,000) and apolipophorin-II (apoLp-II, Mr congruent to 80,000), both of which are glycosylated as shown by staining with periodate-Schiff reagent. The protein complex is composed of 49% protein and 51% lipids. 3. The finding of lipophorin in tsetse fly haemolymph suggests that, although these flies primarily utilize proline for their energy needs, there is an active transport mechanism for the supply of lipid requirements.

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.

Over the last six years there has been a tremendous development of infrastructure projects in virtually all corners of Kenya. This has taken the form of Road Improvement Project, Water and sewerage improvement project and the Electricity Transmission Improvement Project as envisioned in the Kenya Vision 2030. The purpose of this paper is to investigate the principles of compulsory land acquisition and way leaves in the three sectors in Kenya by looking at the current legislative framework governing the entire process of acquisition. In considering the process, the paper explores the various provisions of the relevant act which governs the particular utility envisaged for improvement project component in the Kenya Vision 2030. A critical evaluation of the procedures adopted is outlined in each case and the general public apprehensions towards such acquisitions. The second part of the paper focuses on suggestions on the choice of valuation methodology in making claims for compensation for land for various infrastructure projects in Kenya. This is borne out of the fact that there appear to be very little standardization in the methods adopted by the various bodies. The paper cites several cases under the Electricity Transmission Improvement Project where a large proportion of way leaves are dealt with at local level, with little consistency. Coupled to this is the public concern that electricity lines have potentially serious health effects that continue to attract research and media interest. The paper concludes with a description of the various cases on how to improve compensation paid to those affected by compulsory acquisition in cases of land and way leaves.

Untreated maternal syphilis during pregnancy will cause adverse pregnancy outcomes in more than 60% of the infected women. In Nairobi, Kenya, the prevalence of syphilis in pregnant women of 2.9% in 1989, showed a rise to 6.5% in 1993, parallel to an increase of HIV-1 prevalence rates. Since the early 1990s, decentralized STD/HIV prevention and control programmes, including a specific syphilis control programme, were developed in the public health facilities of Nairobi. Since 1992 the prevalence of syphilis in pregnant women has been monitored. This paper reports the findings of 81,311 pregnant women between 1994 and 1997. A total of 4244 women (5.3%) tested positive with prevalence rates of 7.2% (95% CI: 6.7-7.7) in 1994, 7.3% (95% CI: 6.9-7.7) in 1995, 4.5% (95% CI: 4.3-4.8) in 1996 and 3.8% (95% CI: 3.6-4.0) in 1997. In conclusion, a marked decline in syphilis seroprevalence in pregnant women in Nairobi was observed since 1995-96 (P<0.0001, Chi-square test for trend) in contrast to upward trends reported between 1990 and 1994-95 in the same population. PIP: This study presents the trend in syphilis prevalence among 81,311 pregnant women in Nairobi, Kenya, from 1994 to 1997. Clinic nurses performed syphilis serology using a rapid plasma reagin (RPR) card test in 10 NCC clinics and Chi square; these were used to study trends over time. Results showed that a total of 4244 women (5.3%) tested positive with prevalence rates of 7.2% (95% CI: 6.7-7.7) in 1994, 7.3% (95% CI: 6.9-7.7) in 1995, 4.5% (95% CI: 4.3-4.8) in 1996, and 3.8% (95% CI: 3.6-4.0) in 1997. Thus, a significant decrease in syphilis seroprevalence among pregnant women in Nairobi was observed since 1995-96, by contrast with the rising trend in syphilis prevalence reported in 1990 and 1994-95 in the same population. This decline was attributable in large part to the syphilis control program initiated in Nairobi in June 1992, which focused on sexual behavior modifications, changes in health care seeking behavior and improved health care services.
