Childhood vesicolithiasis in Hazara division of N.W.F.P. Pakistan

100 children up-to 5 years of age, from various hospitals of Hazara Division with vesicolithiasis were included in this study. This study was carried out from January 1990 to December 1992. A similar number of age and sex matched normal children as control group were also studied. The highest incidence was between 1-3 years of age [44%]. Almost all cases were reported in males. Most of the cases belonged to low socio-economic class. Dehydration seemed to be an important etiological factor. Voiding difficulties, frequency of micturition and acute retention were the commonest presenting symptoms

Long-term results of gill Vernet procedure for vesica-ureteric reflux

The authors reviewed nine children with 15 refluxing urters who had Gil Vernet procedure at Salmaniya Medical Complex between 1984 and 1987. The follow-up period ranged between 7.5 to 11 years with a mean of 9.3 years. All the ureters stopped refluxing. Three patients presented with dysuria and lower abdominal pain. These three patients had urinary bladder claculi over protruding non-absorbable sutures. Gil Vernet procedure stops vesico-ureteric reflux, but the non-absorbable sutures have the risk of urinary bladder claculus formation. It is recommended to replace the non-absorbable sutures by long lasting inverted buried absorbable sutures

Pathophysiology of cholesterol gallstone disease

The purpose of the present paper is to review the current knowledge about cholesterol gallstone disease. It is generally accepted that the formation of cholesterol gallstone requires three major pathogenic defect, namely, supersaturation, nucleation and crystal growth as well as disorder of gallbladder motility. The supersaturation is necessary but not sufficient to explain stone formation. It has been suggested that nucleation is the key factor for gallstone formation. However, those three factors are necessary for the formation of cholesterol gallstones, and the presence of just one or two factor does not lead to stones. We also touch briefly on the results form studies performed in Mexico in this area

Manejo quirúrgico oportuno de la pancreatitis biliar: la importancia del factor tiempo / Timely management of gallstone pancreatitis: importance ot eh time factor

Objetivo: Establecer cuál es el momento más oportuno para interrumpir la patogenia de la pancreatitis de origen biliar mediante cirugía. Sede: Hospital Central Norte de Petróleos Mexicanos, México, D.F. Diseño: estudio retrospectivo, observacional, comparativo y transversal de 29 pacientes consecutivos con pancreatitis biliar y que fueron divididos en 2 grupos; el grupo I, pacientes manejados "agresivamente" y operados en las primeras 48 horas de ingreso; y el grupo II, pacientes manejados médicamente en un principio y operados pasadas las primeras 48 horas de internamiento. Resultados: El grupo I incluyó 12 casos y el II a 17. Ambos fueron comparativos ya que no hubo diferencias estadísticamente significativas en cuanto a factores de riesgo, severidad del cuadro o tipo de operación efectuada. La morbilidad, mortalidad y estancia hospitalaria fueron mayores para el grupo I, aunque sin significado estadístico; no así la tasa de reintervenciones, que fue de 16.6 por ciento para el grupo I y 0 por ciento para el II. Conclusión: Recomendamos operar a este tipo de pacientes sólo hasta que el cuadro agudo dé muestras de remisión, pues no prolonga su estancia hospitalaria y sí, en cambio, permite evitar reintervenciones y mejorar las condiciones generales del paciente
