An ileal segment was interposed between the renal collecting system and bladder in 4 cases. The surgical technique is outlined, with emphasis on the pyelo-infundibulocalico-ileal anastomosis and other technical aspects. The ileal ureter is recommended in selected cases of recurrent renal calculi and nephrocalcinosis with associated nephrolithiasis.

Acetylcholinesterase activity was measured in rectal-biopsy specimens obtained from nineteen children. Seven children in whom the diagnosis of Hirschsprung's disease was established were found to have a significantly higher enzyme activity than the twelve in whom this diagnosis was excluded. The estimation may prove to be of value in the diagnosis of Hirschsprung's disease.

The clinical, endoscopic, and biochemical effects of metiamide, a histamine H2-receptor antagonist, in therapeutic dosage have been studied in a 28-day open trial in patients with duodenal ulcer disease. A good symptomatic response, combined with a 72% ulcer healing rate was observed. There were small but significant rises in plasma creatinine, serum glutamic oxaloacetic transaminase, and serum lactate dehydrogenase during treatment. Small quantities of amino acids appeared in the urine, and the heart size increased slightly. It is concluded that histamine H2-receptor antagonism may be an important therapeutic approach to duodenal ulcer disease.
Dale, G., Goldfinch, M. E., Sibert, J. R., and Webb, J. K. G. (1975). Archives of Disease in childhood, 50, 731. Plasma osmolality, sodium, and urea in healthy breast-fed and bottle-fed infants in Newcastle upon Tyne. Plasma osmolality, sodium, and urea were measured on samples from 50 healthy infants, aged between 18 and 125 days, attending child health clinics in Newcastle upon Tyne. 3 infants had osmolalities greater than 300 mOsm/kg, a lower incidence of hyperosmolality than that previously reported. There was a difference (P less than 0-001) between the plasma urea levels of breast-fed and bottle-fed infants, but not between the osmolalities of these groups. The mean plasma urea of bottle-fed babies was 53 mg/100 ml (SD 12-47), 50-1 mg/100 ml (SD 10-9) if additional solids were being given, and 18-4 mg/100 ml (SD 7-81) for breast-fed babies. There was little difference between the plasma sodium levels of each group. The mean plasma sodium for all groups combined was 135-2 mmol/1 (SD 2-3); no plasma sodium exceeded 140 mmol/1.

In a series of 20 patients with bile peritonitis seen during a 15-year period, 15 were men and 5 women, with an average of 72 years. They represented 1.8% of 1123 patients with acute cholecystitis admitted during the same period. Three patients were not operated upon and all died, while 5 of 17 operated patients died. The high mortality rate is due to a delay in diagnosis and treatment. Early operative treatment of acute cholecystitis should be resorted to whenever possible.
