Case ReportsNonocclusive mesenteric ischemia associated with propranolol overdose: implications regarding splanchnic circulation.
We describe a case of massive propranolol overdose in a healthy 19-year-old woman associated with isolated mesenteric ischemia following shock. We postulate that endogenous catecholamine release from shock combined with massive beta-adrenergic blockade led to severe splanchnic vasoconstriction from unopposed alpha-adrenergic activity. This case supports current thinking regarding the effect of vasoactive mediators on the gastrointestinal tract in humans and might be relevant to the mechanism of action of propranolol in the prophylaxis of variceal bleeding.

Comparative Study Clinical Trial Controlled Clinical TrialComparison of efficacy of a glucose/glycine/glycylglycine electrolyte solution versus the standard WHO/ORS in diarrheic dehydrated children.
It was hypothesized that a mixture of glucose and amino acids enhances sodium and water absorption and therefore diminishes the volume of oral rehydration solution, stool output, and duration of diarrhea. To investigate this hypothesis, the efficacies of two oral rehydration solutions (ORS) were compared, one containing (mmol/L): Na+ 90, K+ 20, Cl- 80, citrate 10, glucose 67, glycine 53, and glycylglycine 30, yielding an osmolality of 350 mosmol/kg H2O, and the other, the standard ORS recommended by the World Health Organization, containing the same electrolyte concentrations and only glucose 110 mmol/L, yielding 310 mosmol/kg H2O. ⋯ The only statistically significant difference was the mean time between admission and the last diarrheic stool. The glycylglycine/glycine/glucose electrolyte solution was found to be suitable for rehydration, but not to have an advantage over the standard WHO/ORS.

Case ReportsAscites complicating ventriculoperitoneal shunts.
Ventriculoperitoneal shunts are currently a standard therapy for obstructive hydrocephalus. These shunts are associated with a variety of abdominal complications, one of which is the development of ascites. We report an 11-year-old girl with a ventriculoperitoneal shunt in whom a low-grade peritoneal infection presented with ascites. This case demonstrates the importance of diagnostic paracenteses, appropriate antibiotic therapy and the potential need to establish an alternative route for cerebrospinal fluid diversion in patients with ventriculoperitoneal shunts and ascites.

Hypernatremic diarrheal dehydration treated with oral glucose-electrolyte solution containing 90 or 75 mEq/L of sodium.
Of 33 infants with hypernatremic dehydration (serum Na+ of greater than or equal to 150 mEq/L) 7 were excluded, 6 because severe alteration of the level of consciousness or shock precluded oral rehydration and 1 because he was given glucose-electrolyte solution plus water. We studied the remaining 27 infants. Twenty (group A) were treated with the World Health Organization-recommended oral rehydration solution (90 mEq/L Na+) and seven (group B) were treated with Pedialyte-RS (Abbott Laboratories Ltd.; 75 mEq/L Na+). ⋯ This patient had high stool output and failed to become rehydrated after 24 h of unsuccessful oral rehydration. None of the patients had seizures or persistent CNS dysfunction. We conclude that the slow administration of oral rehydration solutions containing either 90 or 75 mEq/L Na+ is a safe and effective treatment of hypernatremic dehydration.

Randomized Controlled Trial Comparative Study Clinical TrialPooled pasteurized breast milk and untreated own mother's milk in the feeding of very low birth weight babies: a randomized controlled trial.
It has been shown that milk derived from mothers with term infants is not optimal for premature babies. There is also concern about the effect of heat sterilizing breast milk. At Baragwanath Hospital, the majority of mothers remain with and care for their premature babies. ⋯ This occurred in spite of the fact that there was little difference, especially in terms of energy content, between the two types of breast milk. This was due to the fact that the pooled pasteurized milk was also largely obtained from mothers of premature babies. It is suggested from our data that slower weight gain in the group receiving the pooled pasteurized milk could be due to the pasteurization, which probably destroys heat-labile milk lipase.
