Acute pancreatitis caused by penicillin.

Acute pancreatitis in childhood is a rare condition but should still be considered in all children presenting with abdominal pain. A complete history and physical exam with emphasis on recent trauma, infection, chronic diseases, and current medications should be obtained. Numerous and varied drugs have been implicated in the development of pancreatitis.

Renal transplantation in multiple myeloma. Case report and review of the literature.

A patient with end-stage renal disease and known benign monoclonal gammopathy underwent kidney transplantation at Westchester County Medical Center, Valhalla, NY. After surgery, during routine follow-up, the patient had laboratory evidence of frank multiple myeloma. However, she did not show any clinical signs or symptoms of the disease.

Do changes in end-tidal PCO2 quantitatively reflect changes in cardiac output?

In anesthetized patients, acute decreases in cardiac output (CO) are often reflected as decreases in end-tidal CO2 tension (PETCO2), but the quantitative relationship between the changes in CO and the changes in PETCO2 is uncertain. We hypothesize that a quantitative relationship can be demonstrated if timing of the measurements in each episode of hemodynamic perturbation is standardized. In 24 patients undergoing abdominal aortic aneurysm surgery with constant ventilation, we prospectively performed 33 measurements of CO, PETCO2, and CO2 elimination (VECO2) within 10 min of hemodynamic changes.
