W DRMUTHOMIJAMES. "Oerke, E. C, Meier, A., Lienemann, G., and Muthomi, J. 2002. Incidence and control of Fusarium species causing head blight in the Rhineland, Germany. Pages 32-44 in: Wissenschaftlichen Fachtagung: Fusarium-befall and Mykotoxinbelastung von Getreide Schadv.". In: Wissenschaftlichen Fachtagung, Landwirtschaftliche Fakult. Landwirtschaftliche Fakult; 2002. Abstract
Fusarium culmorum is an important pathogen of wheat causing seedling blight, foot rot, and head blight (FHB) or scab. The pathogen is dominant in cooler areas like north, central and western Europe. The fungus reproduces asexually by means of conidia, which form the main mode of dispersal. Head blight is by far the most serious concern of Fusarium infection on pre-harvest wheat and other small grain cereals. The significance of F. culmorum in wheat production is attributed to both head blight and mycotoxin contamination of the grain harvested from infected ears. Ear infection mainly occurs during anthesis and is favoured by wet weather or high humidity and warm temperatures. The major mycotoxins produced by F. culmorum are deoxynivalenol, nivalenol and zearalenone, which are a potential health hazard for both humans and animals. The mycotoxins, especially deoxynivalenol, are believed to play a role in disease development. Available options of managing Fusarium head blight include use of fungicides, cultural practices, resistant varieties and biological agents. However, no wheat variety is completely resistant to Fusarium head blight while fungicides are at most 70% effective against natural infection. This review seeks to document and infer information on F. culmorum, with special emphasis on wheat head blight infection process, mechanisms of mycotoxin production, the role the mycotoxins play in pathogenesis, and the possible management options.
W PROFNJENGALYDIAH, Kariuki DN, S.M.Ndegwa. "Water Labile fluoride from Fresh Raw Vegetable Juices from Markets in Nairobi, Kenya'.". In: Fluoride 38 (3) 205 - 208. UoN; 2005. Abstract

Analysis of water-labile fluoride in fresh vegetable juices from markets in Kenya was conducted by direct analysis with a fluoride ion selective electrode. Among 20 different vegetable juices, the fluoride content ranged from 1.2 mg FIL to 5.4 mg FIL. Some of the juices contained higher fluoride levels than the limits recommended by the World Health Organization for drinking water. Consumption of vegetable juices for healing therapy has become popular, and it is therefore important to consider the fluoride intake from this source. Calculation of the amount of fluoride that may be ingested from the juices based on the recommended formulations shows that the juices make a significant contribution to daily fluoride intake.

Keywords: Fluoride in juices; Fresh vegetables; Nairobi, Kenya; Vegetable juices; Water-labile fluoride.

This paper describes the methodology and presents preliminary results of an economic appraisal of a community based health care project in Kenya. Community health workers, trained for 12 weeks and deployed in two locations in Kenya's Western Province, act as first contact providers of basic health care and promoters of selected health, sanitation and nutrition practices. A Cost Benefit Analysis has been undertaken using the Willingness to Pay approach to compare the costs of the project and its benefits. The benefits are in the form of more easily accessible basic health care and are measured as consumer surplus accruing to the community. Gain in consumer surplus is consequent on the fall of average user costs and rise in utilisation of the project established points of first contact with primary health care. The argument for the economic viability of the project is validated by the large Net Present Value and Benefit Cost Ratio obtained for the whole of the project area and for the two locations separately. Although the evaluation technique used faces the problem of valuation of community time, aggregation of health care services at all points of first contact and the partial nature of cost benefit analysis evaluations, the results are strongly in favour of decentralisation of primary health care on similar lines in the rest of the country.

he distribution of cathinone and d-norpseudoephedrine in Catha edit/is plants from 2 different geographical localities has been investigated. There was no difference in the chemical constituents of Catha material from 2 locali-ties. D-norpseudoephedrine was present in all parts of the plant examined except the root but cathinone was only detected in the young shoots and bran-chlets. It is concluded that the psychostinaulant effect following chewing of young Catha shoots is due to both cathinone and d-norpseudoephedrine with the cathinone being more important since it is 7-10 times more potent than d-norpseudoephedrine.

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

Analysis of 355 cases with fractures of the mandible indicated that 74.9% of the cases were due to interpersonal violence and 13.8% were caused by road traffic accidents. The men to women ratio was 8.4:1 and 75.5% of the fracture cases had single fractures while 24.5% had multiple fractures. In cases with a single fracture, the most commonly involved mandibular site was the body (42.2%). The angle of mandible was most frequently fractured (50.5%) in cases with multiple fractures.

There is a causal relationship between political leadership and economic development. There is evidence that the deterioration of economic conditions in African since independence is owed to poor management of public economic affairs by the incumbent state leadership. This argument implies that whereas the continent may not be very well endowed with natural resources, this may not be held solely responsible for the existing economic woes. Whatever resources exist are capable of generating economic development, indeed economic breakthrough, if they are harnessed and utilized effectively. Conversely, a country may be endowed with enormous natural and human resources, but may remain characterized by poverty and economic backwardness if it is not endowed with visionary, dedicated and rational political leadership capable of appropriating such resources for the purpose of national development and for the prosperity of the citizens.

Persons with congenital or acquired immunosuppression have long been known to have an increased incidence of lymphoproliferative disorders. Unsurprisingly, therefore, the acquired immunodeficiency syndrome (AIDS), caused by the human immunodeficiency virus (HIV), is associated with an increased incidence of lymphoma. Three cases with HIV-associated lymphoma aged 30, 32 and 35 years respectively are presented. Two had cutaneous non-Hodgkin's lymphoma while one had Hodgkin's lymphoma. Standard chemotherapy for lymphoma was given with good tumour regression. Two of the patients died within six months of lymphoma diagnosis due to other complications of HIV.
