OBJECTIVE To evaluate the impact of oral magnesium supplementation on risk factors for end-organ disease in patients with non-insulin-dependent diabetes mellitus (NIDDM). DESIGN A 16-week randomized, double-blind, placebo-controlled crossover trial. SETTING Outpatient center of an academic family medicine residency program. PATIENTS Twenty-eight(More)
The interaction between angiotensin II (ANG II) and catecholamines was examined in nonmammalian vertebrates. ANG II challenge caused a significant pressor response in representatives of the seven vertebrate classes. Additionally, plasma levels of both epinephrine and norepinephrine increased following intravascular ANG II injection in the conscious(More)
Sympathetic nerve activity and in particular renal sympathetic nerve activity were monitored in six conscious dogs subjected to 6 days of intravenous angiotensin (ANG II) infusion (20 ng/kg/min). This was accomplished by measurement of both arterial and renal venous plasma catecholamine concentration. During the initial 4 hours of ANG II infusion, mean(More)
UNLABELLED This study is a retrospective analysis of 124 differentiated thyroid cancer patients who underwent dosimetric evaluation using MIRD methodology over a period of 15 y. The objectives of the study were to demonstrate the clinical use of dosimetry-guided radioactive iodine ([RAI] (131)I) treatment and the safe and effective application of a 3-Gy(More)
STUDY OBJECTIVES Topical nitroglycerin has been reported to prevent skin necrosis from brown recluse spider bites, but this has never been scientifically tested. This study attempts to assess the effects of topical nitroglycerin on experimental Loxosceles reclusa envenomations. METHODS We performed a randomized, blinded, controlled study in an animal care(More)
Venous air embolism during neurosurgical procedures (detected by Doppler Ultrasound and aspiration via a right atrial catheter) was noted in 100 of 400 patients in the sitting position, 5 of 60 patients in the lateral position, 7 of 48 patients in the supine position, and 1 of 10 individuals monitored in the prone position. We confirmed venous air embolism(More)
The opening of voltage sensitive calcium channels is an important event in the progression of irreversible shock, allowing the entry of toxic amounts of calcium (Ca2+) into the cells. Because intracellular magnesium (Mg2+) can efflux through these same channels, changes in serum Mg2+ may reflect the patency of these channels. In this study, electrolytes and(More)
The educator's portfolio provides a mechanism for identifying and evaluating faculty teaching activities. The educator's portfolio has separate areas for educational research, teaching encounters, and educational service. This article describes the components of a traditional educator's portfolio and relates them to the basic scientist's curriculum vitae.(More)
METHODS Thirty-two patients with clinical node-negative breast cancer underwent sentinel node localization study as part of a National Cancer Institute-sponsored multicenter trial. Anatomical and histopathologic characteristics of sentinel lymph node (SLN) and a kinetic analysis of nodal uptake were studied. Patients were injected with 1 mCi/4 ml unfiltered(More)
