Accepted for publication 5 December 1995 A 51 year old woman was transferred to our hospital for surgical treatment of a paracardiac mass. The patient was free of symptoms on admission. The chest x ray and electrocardiogram were normal. Echocardiography showed a large paracardiac mass with a homogeneous acoustic pattern in the right atrioventricular groove. Magnetic resonance imaging also showe...

on its use as a diagnostic aid in the evaluation of closed abdominal injuries, acute pancreatitis, and primary pneumococcal or streptococcal peritonitis. Though no cases were reported in their paper, they also predicted a wider use for the test in the diagnosis of ruptured hollow viscera and bleeding ectopic pregnancies. Later studies have confirmed these observations, especially in relation to...

Filtering procedures remain the most popular surgical option for controlling intraocular pressure (IOP) in medically refractory glaucoma. Incorporation of adjunctive anti fibrotic treatment has enhanced IOP control and prolonged filtering efficacy [1-3], but for various reasons some blebs are prone to failure many months or years later. Sometimes that failure may take the form of hyperfiltratio...

Evidence was obtained regarding the way the O-2-forming NADPH oxidase of human neutrophils is arranged within the plasma membrane. O-2 production by particles from zymosan-activated human neutrophils rose two- to threefold when the particles were assayed in the presence of appropriate concentrations of Triton X-100. The portion of activity revealed by the detergent was not affected by treating ...

Determining an appropriate control for use in acupuncture research remains one of the largest methodological challenges acupuncture researchers face. In general, acupuncture controls fall under one of two categories: (1) sham acupuncture, in which the skin is punctured with real acupuncture needles either fully at nonacupoint locations or shallowly at acupoint locations or both and (2) placebo ...

BACKGROUND/AIMS This study sought to determine the natural course of Crohn's disease (CD) and identify predictors that could indicate responsiveness to corticosteroid (CS) therapy. METHODS Patients with active CD who were treated with oral CS at a single institution between August 1994 and February 2008 were retrospectively reviewed. The clinical outcomes at 1 month, 4 months, and 1 year afte...

Platelet stimulation with ADP results in several responses, including shape change, increase in cytoplasmic ionized calcium concentration [Ca2+]i, an inhibition of adenylate cyclase. 5'-p-Fluorosulphonyl benzoyladenosine (FSBA), which covalently labels an ADP binding site on platelets, blocks platelet shape change but not the inhibition of cyclic AMP levels by ADP, whereas p-chloromercuribenzen...

PURPOSE To evaluate and compare the results and complications of eyes that underwent a phaco-deep sclerectomy (DS) converted into phaco-trabeculectomy due to an intraoperative macroperforation with eyes undergoing uneventful phaco-DS. METHODS The authors reviewed 106 eyes having a planned phaco-DS; 10 of them (9.4%) had to be converted into phaco-trabeculectomy because of a large perforation ...

This clinical policy provides evidence-based recommendations on select issues in the management of adult patients with mild traumatic brain injury (TBI) in the acute setting. It is the result of joint efforts between the American College of Emergency Physicians and the Centers for Disease Control and Prevention and was developed by a multidisciplinary panel. The critical questions addressed in ...

OBJECTIVE To compare the effects of dimethyl sulfoxide (DMSO), 1,2-propanediol (PROH), sucrose, trehalose, concentration of cryoprotectants, equilibration method, and postseeding freezing rate on doe rabbit ovarian tissue preservation after freezing, using fractional experimental design. DESIGN Experimental prospective study. SETTING Research institute in veterinary and agronomic colleges. ...
