In July 1992, 13 parents with children attending a child care center (CCC) developed aseptic meningitis (AM) due to echovirus 30 (E30). To determine the extent of illness and risk factors for transmission, survey and blood specimens were collected from CCC families and teachers and from adult and pediatric controls. Infection was defined as the presence of(More)
The effects of insulin on triacylglycerol/fatty acid cycling (fatty acid reesterification) were studied in 12 normal subjects during euglycemic hyperinsulinemia with the use of stable isotope dilution analysis ([2H5]glycerol and [1-13C]palmitate) in combination with indirect calorimetry. During basal conditions, 5.6 +/- 0.6 mumol.kg-1 x min-1 of fatty acid(More)
Acute appendicitis is the most common nonobstetrical surgical condition of the abdomen complicating pregnancy. Appendectomy reportedly is performed during pregnancy once for every 1,500 deliveries. Although the incidence of appendicitis occurring in pregnant women is considered to be the same as in nonpregnant women, the signs and symptoms, and the(More)
OBJECTIVE Aging is known to be associated with increasing insulin resistance and declining glucose tolerance. The cause for the insulin resistance, however, remains uncertain. In this study, we examined the hypothesis that at least part of the insulin resistance may be attributable to age-related changes in body composition and muscle blood flow rather than(More)
We have studied effects of ethanol on insulin's ability to suppress its own release and on its antilipolytic action in 12 healthy elderly men during euglycemic hyperinsulinemia. Insulin secretion was estimated from plasma C-peptide concentrations. Lipolysis was determined with the two stable isotopes [2H5]glycerol and [1-13C]palmitate. Hyperinsulinemia(More)
We examined the mechanism by which an increase in blood insulin concentration inhibits insulin secretion by the pancreas. To this end, we determined plasma C-peptide concentrations during euglycemic-hyperinsulinemic (approximately 500 pmol/L) clamps in five patients with insulin-dependent diabetes mellitus (IDDM) after combined pancreas and kidney (P/K)(More)
Uterine packing to control obstetrical hemorrhage has been generally discouraged over the past several decades. Intractable uterine hemorrhage postpartum or following an abortion is an extremely vexing management problem for the physician and continues to be a leading cause of maternal mortality. Uterine packing should be considered as a presurgical(More)
We have previously reported that in young men, ethanol caused acute insulin resistance, but compensatory insulin secretion prevented deterioration of glucose tolerance (1). In this study, we tested the hypothesis that elderly men, because of their pre-existing insulin resistance and compromised insulin secretory capacity, may experience worsening of their(More)
Patients with insulin-dependent diabetes mellitus (IDDM) who have undergone combined pancreas and kidney (P/K) transplantation, are hyperinsulinemic and have impaired insulin-stimulated whole body glucose uptake. We have investigated whether their reduced glucose uptake was due to insulin resistance at the tissue level or was caused by reduced muscle blood(More)
