Covered exstrophy is an extremely rare variant of exstrophy-epispadias complex. It is less distressing and easier to manage than classical exstrophy of the bladder. We report three cases of this entity, two associated with anorectal malformation and one with unilateral renal agenesis, along with a review of the literature.
A new variant of esophageal atresia (EA) with tracheoesophageal fistula (TEF) associated with duodenal atresia is reported. The TEF was between the lower pouch and the trachea, with a cystic dilatation in the midportion. The tracheal end of the fistula was obstructed by a membranous septum at both ends of a cystic dilatation, leading to a diagnosis of pure EA (gasless abdomen). After the lower pouch was opened beyond the cystic dilatation, 100 ml nonbilious fluid was obtained. A laparotomy revealed a type III atresia of the first part of the duodenum.
Abdominal cocoon is a rare cause of intestinal obstruction. The authors report four cases (3 boys, 1 girl; age range, 6 to 8 years) that presented with features of intestinal obstruction. There was no history of previous surgery, peritonitis, or prolonged drug intake in any of these cases. One patient presented with acute intestinal obstruction and gangrene of bowel. The etiology, preoperative diagnosis, and management of this condition are discussed.
OBJECTIVES: To evaluate the efficacy of intralesional triamcinolone in enhancing regression in various type of hemangiomas. SETTING: Outpatients department of a teaching hospital Subjects: One hundred and five patients with rapidly growing surface hemangioma. The age ranged from 1 month to 15 months (mean 7 months). INTERVENTION: Intralesional triamcinolone administered at monthly intervals, ranging from single injection to 7 injections (mean 3.6 injections). MAIN OUTCOME MEASURE: Regression of the hemangioma. RESULTS: The overall response rate was 88.6% (excellent 51.4%, and good 37.2%). Maximum response was observed in children below 1 year of age (> 90%), lesions over the face (92.8%) and strawberry hemangiomas (99.9%). CONCLUSION: Intralesional administration of triamcinolone devoid of systemic side effects and an effective initial modality for rapidly growing hermangiomas.

Primary bladder stone is a common pediatric surgical problem in developing countries. Many theories are prevalent. The stone matrix theory is based on increased excretion of its precursor, the uromucoid (the urinary mucoprotein). Uromucoid, studied in urine and stones by the electroimmunodiffusion technique in 49 cases with controls, showed significantly increased excretion in stone cases. Family income and serum protein were the only important influencing factors (negative). Causal relationship between uromucoid excretion, stone matrix, and pediatric bladder stones is discussed. Methylene blue decreased uromucoid excretion but not magnesium oxide, vitamin C or B6 (four common therapeutic drugs for prevention/dissolution of urolithiasis).
