Comparison of oral cholecystography (OCG) with real time ultrasonography in the diagnosis of cholelithiasis at the Tikur Anbessa Hospital, Addis Ababa, Ethiopia.

A prospective study of the accuracy of real time ultrasonography in the detection of gallstones was undertaken in 180 patients from February 1987 to February 1988. The ultrasound findings were compared with single dose oral cholecystography (OCG), and with the surgical findings where surgery was undertaken. Ultrasonography gave more accurate results than OCG, with an overall accuracy in the surgically proven patients of 97.1%, no false positive findings and a 2.9% false negative rate. OCG gave an accuracy of 80% with no false positive findings and a 20% false negative rate. Ultrasound was particularly valuable where there was non visualisation of the gall bladder at OCG, giving an overall accuracy of 93.3% in such patients. Ultrasonography is a non invasive, simple, safe and economic diagnostic test of high accuracy in the diagnosis of cholelithiasis and of particular benefit in those patients unsuited for OCG.

Unusual manifestations of deep mycoses due to Streptomyces somaliensis.

The incidence of deep mycotic infection due to Streptomyces somaliensis in Kenya and the Sudan is referred to and the common radiological appearance reviewed. Two patients having unusual manifestations are reported. In one skull vault involvement caused raised intracranial pressure. The other patient presented with a pathological fracture of the femur and subsequently acquired a further infection at the opposite ankle.

Schistosomiasis haematobia in coast province Kenya. Relationship between egg output and morbidity.

Several studies of schistosomiasis haematobia in Africa have revealed a correlation between intensity of infection as measured by urine egg counts and severity of disease as determined by intravenous pyelography. The present study consisted of a survey of 390 school children in the coastal area of Kenya involving a single egg count, and intravenous pyelograms in a stratified random sample of 69 children; the results showed a greater prevalence of urinary tract disease in those with higher intensities of infection. This survey was then followed by a more detailed study in which nine consecutive daily egg counts were done on 121 children; 17 of these children, subdivided into three groups with different intensities in infection, were given intravenous pyelograms. The results were similar in the 11 children with minimal and moderate counts (averaging, respectively, less than 1 egg and 167 eggs/10 ml urine daily), with approximately 30% having bladder or renal abnormalities. In comparison, all of the six children with heavy counts (averaging 1,288 eggs/10 ml urine daily) had bladder lesions and five of them had renal lesions.
