    Notes: Summary Bilateral renal hypoplasia with oligomeganephronia, associated with bilateral tapetoretinal degeneration was observed in a child; this association has been reported only once before. Light, ultrastructural and immunofluorescent microscopic studies of the renal tissue were performed. The glomeruli were few and hypertrophic, with numerous mesangial cells, mesangial deposits, focal glomerular sclerosis and prominent thickened basement membrane. Two types of tubular changes were observed: focal necrosis of proximal tubules and focal atrophy of tubules surrounded by a thickened basement membrane. Mild fibrosis with few lymphocytes could be observed in the interstitium. A congenital reduction in the number of nephrons, related to a yet unknown pathological process may explain these morphological changes in part.

    Notes: Abstract Ten clinical episodes of acute pancreatitis (AP) occurred in six patients (mean age 10 years, range 3–15 years) with chronic renal failure (CRF) during a 9-year period (1977–1986). The underlying cause of CRF was vesicoureteral reflux (2); urethral valves (1); ureterohydronephrosis (1); nephronopthisis (1) and a haemolytic uraemic syndrome which occurred 12 years before (1). In all patients a diagnosis of AP was established both on clinical grounds and with a serum amylase level of 〉600 IU/1. In 3 patients laparotomy was performed because of suspected appendicitis. All patients required exclusive parentenral feeding (mean duration 25 days) and 2 patients had a partial pancreatectomy. No patient developed pancreatic pseudocysts, 2 patients experienced one relapse (3 and 21 months later) and 1 patient had two relapses and died. Mean duration of follow up was 3 years (range 1–10 years). Possible aetiological factors were: choledochal cyst (1); parotitis without a rise in mumps antibodies (1); familial dyslipidaemia but without AP in other family members (1), and aluminium intoxication with hypercalcaemia and convulsive encephalopathy treated with valproic acid in 1 patient. Severe hyperparathyroidism with radiological signs was absent in all patients. Transplantation had been performed either before AP in 2 patients (1 and 3 years before AP) or had followed AP in 1 patient (7 years after) without occurrence or relapse of AP.
