OBJECTIVE To report a patient with a probable acute tubular necrosis (ATN) induced by chronic exposure to polyethylene glycol (PEG)-400 via long-term, massive dosage of intravenous lorazepam. CASE SUMMARY A 57-year-old man with a history of alcohol abuse was admitted to the intensive care unit for acute respiratory failure. Lorazepam therapy was initiated(More)
Relationships between testosterone plasma levels and evoked vocal responses of males of the leptodactylid frog Batrachyla taeniata from southern Chile were studied. Evoked vocal responses were elicited in the field with playbacks of a synthetic imitation of the conspecific advertisement call and variants of this signal for which different temporal(More)
OBJECTIVE To assess the association between postoperative central venous oxygen saturation (ScvO(2)) and arterial lactate with outcome after cardiac surgery. DESIGN Prospective observational study. SETTING University-affiliated tertiary care hospital. PARTICIPANTS Patients after coronary artery bypass and/or valve surgery. INTERVENTIONS None. (More)
To study the effect of cardiac glycosides on platelet function, we obtained serial blood samples from 18 normal male volunteers before and 3, 5, and 7 weeks after beginning digoxin therapy (0.375 mg daily). The combined effect of digoxin and nifedipine (mean dose, 57 mg/day) was assessed during the 5th week. Spontaneous platelet aggregation and platelet(More)
A patient with acute bacterial endocarditis in whom ischaemic contracture of the left ventricle (stone-heart syndrome) developed during aortic and mitral valve replacement had an emergency implantation of an intracorporeal partial artificial heart (an abdominal left-ventricular assist device of ALVAD). This device functioned as a total artificial heart for(More)
Particulate microemboli and in vitro platelet aggregation were studied in blood of patients during cardiac operations with an electronic particle size analyzer. A small gradient of microemboli developed on passage of blood through a bubble oxygenator but not through a membrane oxygenator. However, with both types of oxygenators, there was a sustained(More)
The effects of changes in arterial carbon dioxide tension (PaCO2) on the oxygenation of tissues in 34 patients undergoing surgery for aortocoronary bypass were studied while temperature, systemic blood flow, and the delivery of oxygen to the peripheral tissues remained constant. Mixed venous and superior vena caval oxygen tensions (PvO2 and PsvcO2,(More)
The work herein examines in vitro the kinetics of platelet aggregation in response to the fluid-shearing stress imparted by a rotational viscometer. Aggregation is expressed through changes in particle size histograms and total particle count. Platelet aggregation commenced above 2000 sec-1 shear rate and was stable above 5000 sec-1. Activation by shear(More)
With recent advances in laparoscopy, specifically the development of laparoscopic splenectomy, a complete laparoscopic Hodgkin's staging procedure is now possible. Using five trocars and the patient in the right semidecubitus position, six laparoscopic staging procedures were performed. All were stages IIA or IIB pre-operatively, and none were upgraded to(More)
