Right adrenal gland neuroblastoma infiltrating the liver and mimicking mesenchymal hamartoma: A case report.

Introduction: Neuroblastoma is the most common extracranial solid pediatric malignancy. The most common site is abdomen with predominance of suprarenal medulla. Infiltration of the tumour to the liver is rare.

Long-term follow-up of 120 patients after hepaticojejunostomy for treatment of post-cholecystectomy bile duct injuries: A retrospective cohort study.

Background: Long-term follow-up is essential for assessment of success of the surgical repair of post-cholecystectomy bile duct injuries (BDI). Factors affecting the long-term outcome and satisfactory length of follow-up have been little reported in the literature. The aim of this study is long-term evaluation of hepaticojejunostomy regarding clinical, radiological, laboratory and quality of life assessment.

Biochemical studies on bilharzial and nonbilharzial hyperoxaluria: effect of pyridoxine and allopurinol treatment.

The urinary excretion levels of oxalic acid, calcium, kynurenic, and xanthurenic acids and serum pyridoxal and pyridoxal phosphate concentrations were determined for nonbilharzial and bilharzial hyperoxaluric patients with or without urinary stones. The effects of pyridoxine and allopurinol treatment were also studied. The different groups studied showed elevated levels of urinary oxalic acid, calcium, kynurenic, and xanthurenic acids as well as decreases in serum pyridoxal and pyridoxal phosphate concentrations.

Hepatic microsomal enzymes in Schistosoma mansoni-infected mice: I. Effect of duration of infection and lindane administration on dimethylnitrosamine demethylases.

The prevalence of schistosomiasis in Egypt, its suspected relationship to carcinoma of the bladder, and the inevitable exposure of schistosomal patients to insecticides prompted the undertaking of this study. Dimethylnitrosamine (DMN) demethylases, responsible for the activation of DMN, were assessed in the hepatic microsomes from albino mice under the influence of Schistosoma mansoni infection and/or lindane administration. DMN-demethylase I responded to infection by an early increase in activity, reaching a peak 30 days after disease induction and declining sharply afterwards.

Hepatic microsomal enzymes in S. mansoni infected mice: II. Effect of duration of infection and lindane administration on aminopyrine demethylase and aniline hydroxylase.

The time course of effects of S. mansoni infection on hepatic microsomal drug metabolizing enzymes was studied in swiss albino mice. Aminopyrine demethylase and aniline hydroxylase showed increases in activity, reaching a peak 30 days post infection.
