Surgical excision of an insulinoma results in dramatic reversal of hypoglycemic symptoms. Laparoscopic resection, if feasible, could reduce postoperative discomfort. Successful laparoscopic resection of an insulinoma is described. Preoperative studies failed to visualize the tumor; however, it was visualized and then imaged successfully during surgery. The(More)
Dual-energy x-ray absorptiometry (DEXA) is a relatively new method of assessing body composition in humans. In the current study, DEXA was analyzed for accuracy and precision by using both anthropomorphic phantoms and a combination of body composition techniques in humans. Satisfactory precision for measurement of total body fat, fat-free mass, and total(More)
OBJECTIVE To develop insight into resident physician attitudes about inpatient hyperglycemia and determine perceived barriers to optimal management. METHODS As part of a planned educational program, a questionnaire was designed and administered to determine the opinions of residents about the importance of inpatient glucose control, their perceptions(More)
Excess free fatty acid release (rate of appearance) is seen in overnight postabsorptive, upper body obese women and, if present postprandially, could contribute to glucose intolerance. These studies examine the antilipolytic effect of a mixed meal in upper body obese, lower body obese, and nonobese women and the contribution of meal triglyceride fatty acids(More)
BACKGROUND Little is known about management of hyperglycemia in inpatients. OBJECTIVE To gain insight into caring for hospitalized patients with hyperglycemia. DESIGN Retrospective analysis. SETTING Teaching hospital. PATIENTS Data on all patients discharged between January 1, 2001, and December 31, 2004 with a diagnosis of diabetes or hyperglycemia(More)
Whether changing from a high-fat diet to an isoenergetic, low-fat, high-complex-carbohydrate diet results in thermogenic benefits is controversial. Brief dietary interventions and failure to account for the potential influence of body-fat distribution on energy metabolism could have confounded the interpretation of previous studies. To address these issues,(More)
To determine whether estrogen directly affects effective adipose lipolysis, palmitate rate of appearances ([14C]palmitate) was measured in 15 postmenopausal women. Each volunteer was studied after > or = 2 mo of estrogen treatment and again after > or = 2 mo of estrogen deficiency. Plasma hormone concentrations were controlled and identical on the 2 study(More)
PURPOSE Individuals whose diabetes is being treated in the outpatient setting via an insulin pump often wish to maintain this therapy during hospitalization. The authors propose guidelines for management of patients on insulin pumps who require a hospital admission. METHODS A collaborative interinstitutional task force reviewed current available(More)
Obesity is a growing worldwide epidemic, increasingly addressed through surgical options for weight loss. Benefits of these operations, such as weight loss and improvement or reversal of obesity-related comorbidities, are well established; however, postoperative complications do occur. This article will evaluate common causes for hospital admissions in the(More)
PURPOSE The study reviewed the interrelationships of diabetes mellitus and coccidioidomycosis. SUBJECTS AND METHODS We conducted a retrospective review of the medical records of immunocompetent patients with coccidioidomycosis who were treated at our academic medical institution between January 1, 1999, and October 31, 2003, to compare those with and(More)
