Posterior urethral valves in childhood : experience in a center with scarce facilities

Objective: Posterior urethral valves (PUV) are the most common congenital causes of lower urinary tract obstruction in male children; but few cases have been reported from Nigeria. In this study we describe our 7-year experience of management of PUV in children in order to increase the awareness of this condition in our environment. Patients and Methods : This is a report of 41 consecutive children with PUV who were managed at the Jos University Teaching Hospitals (JUTH); Jos; Nigeria; from June 2000 to April 2006. Their age at presentation ranged from 2 days to 15 years (mean: 2.5 years). The relevant clinical; laboratory and radiological data were entered into a database and analyzed.Results: Twenty-eight patients presented with a condition highly suspicious of PUV; while 7 patients presented with other urological conditions. Six patients presented with non-urological symptoms which caused a delay in diagnosis and institution of treatment. Voiding cystourethrography was diagnostic in all cases. In the majority of patients (n=31); management consisted of transurethral balloon avulsion of the valves yielding a satisfactory outcome in over 80. Conclusion : Although this study was restricted to one hospital; there appears to be a high incidence of PUV in children in North Central Nigeria. An increased awareness of varied clinical features; a high index of suspicion and simple conservative treatment by balloon avulsion of PUV would improve the outcome.of the patients. Urethral stricture was the main complication (which responded to serial dilatation) and occurred in 3 patients. The postoperative mortality rate was 2.6

Management of Conjoined Twins : a Report of Two Sets

Background: Conjoined twinning is a rare congenital anomaly. We present here; our experience in the management of two sets of conjoined twins at a Teaching Hospital in north central Nigeria. Method: Data of conjoined twins managed at the Jos University Teaching Hospital in 1987 and 2004 were retrospectively collated and analyzed. Result: Two sets of pyopagus tetrapus conjoined twins were managed within the period; one was a set of triplets. The conjoined pairs in both sets of twins were females. None of the twins was diagnosed prenatally. Both sets of conjoined twins were delivered spontaneously by vaginal route. Emergency surgical separation was undertaken in both sets be- cause of deteriorating anencephaly in one twin in the first set and anorectal malformation and intestinal obstruction in one twin in the second set. Both sets of twins died after separation. Conclusion: Our experience showed that separation of conjoined twins may be associated with high mortality. Sepsis and electrolyte imbalance appear to be the major causes of morbidity and mortality; particularly when the resultant skin defects are large

Influence of variety of Nigerian rice on experimental peptic ulceration

The susceptibility of rats prefed with five varieties of rice to indomethacin - induced gastric ulceration was studied. The degree of ulceration was significantly higher (P0.001) in rats fed with white polished rice than in any of the two local rice varieties (Tapa and Ofada). Ulceration was significantly lower (P 0.001) in the brown rice-fed rats than with the polished rice-fed rats. This study indicates that the modern milling processes which improve the palatability and digestibility of rice remove most of the required vitamins along with the bran. Lack of these vitamins makes animals susceptible to gastric ulceration
