- Forty-four children were studied to compare the pathogenesis of fever in cerebral malaria, uncomplicated malaria and measles at the Eldoret District Hospital (EDH). A control group of normal children was used. The three patient groups were studied for three consecutive days measuring skin and core temperature three-times a day using the Liquid Crystal Device (LCD) thermometer. A statistical analysis of the results within and between the groups was carried out for core and skin temperature over the study period. No statistical differences were found between the groups for either the skin or the core temperature, but a significant statistical difference was demonstrated between the core and the skin temperature for all of the groups for each of the three days. No statistical difference was found when the differences between the core and skin temperature were compared between cerebral malaria and uncomplicated malaria. The possible roles of fever in morbidity and mortality are discussed, with special reference to cerebral malaria.

- BACKGROUND:The clinical presentation of cerebral malaria in children in the highlands has not been documented.OBJECTIVE:To describe the presentation of cerebral malaria in the age group one to twelve years.DESIGN:Prospective study conducted from May to September 1997, the rainy season during which malaria occurs in epidemics in the highlands of Kenya.SETTING:Paediatric wards of the Moi Teaching and Referral Hospital, Eldoret which is the Teaching Hospital for Moi University and the referral centre for surrounding districts of Western Kenya, with an altitude of over 2000 metres above sea level.PATIENTS:Twenty three consecutive children aged one to twelve years with cerebral malaria as defined by the WHO were studied. All children were treated with the standard quinine regimen for cerebral malaria.RESULTS:Majority of the children were six to ten years of age with 95.7% having a normal weight for age. 91.3%, 89.5% and 72.2% had fever, headache and convulsions respectively. 68.1% had a short duration of illness (less than three days) with only 9.5% presenting with hypoglycaemia. Severe anaemia was not observed but 72% had mild to moderate anaemia. Hyperparasitaemia (parasite counts greater than 100,000 per microlitre) was found in majority of the cases.CONCLUSION:Cerebral malaria presentation in the highlands is similar to that among non-immune populations and is an acute fulminant illness presenting with coma, hyperparasitaemia, fever and convulsions in children with normal nutritional status.

- OBJECTIVES:To report the initial experience of an international group of investigators in identifying mutations in the BRCA1 breast and ovarian cancer susceptibility gene, to assess the spectrum of such mutations in samples from patients with different family histories of cancer, and to determine the frequency of recurrent mutations.DESIGN:Nine laboratories in North America and the United Kingdom tested for BRCA1 mutations in DNA samples obtained from a total of 372 unrelated patients with breast or ovarian cancer largely chosen from high-risk families. Three of these laboratories also analyzed a total of 714 additional samples from breast or ovarian cancer cases, including 557 unselected for family history, for two specific mutations that had been found to recur in familial samples.PARTICIPANTS:A total of 1086 women with either breast or ovarian cancer.MAIN OUTCOME MEASURE:The detection of sequence variation in patients' DNA samples that is not found in sets of control samples.RESULTS:BRCA1 mutations have now been identified in a total of 80 patient samples. Thirty-eight distinct mutations were found among 63 mutations identified through a complete screen of the BRCA1 gene. Three specific mutations appeared relatively common, occurring eight, seven, and five times, respectively. When specific tests for the two most common mutations were performed in larger sets of samples, they were found in 17 additional patients. Mutations predicted to result in a truncated protein accounted for 86% of the mutations detected by complete screening.CONCLUSIONS:The high frequency of protein-terminating mutations and the observation of many recurrent mutations found in a diverse set of samples could lead to a relatively simple diagnostic test for BRCA1 mutations. More data must be accumulated to address specifically the sensitivity and specificity of such a diagnostic testing procedure and to better estimate the age-specific risk for breast and ovarian cancer associated with such mutations.
