BACKGROUND Diltiazem reduces non-fatal reinfarction and refractory ischaemia after non-Q-wave myocardial infarction, an acute coronary syndrome similar to the incomplete infarction that occurs after successful reperfusion. We postulated that this agent would reduce cardiac events in patients after acute myocardial infarction treated initially with(More)
PURPOSE To characterise an Irish kindred with apparent autosomal dominant peripheral retinal lesions and peripapillary crescents associated with retinal breaks and uveitis and assess whether these findings were associated with altered homocysteine metabolism. METHODS Family members were followed prospectively and regularly examined. Molecular genetic(More)
BACKGROUND AND PURPOSE Previous T2*-weighted magnetic resonance imaging (MRI) studies have used white matter lesion (WML) central veins to distinguish multiple sclerosis (MS) from its mimics. To be clinically applicable, the "central vein sign" needs to be detectable across different T2* sequences. Our objective was to determine if the central vein sign is(More)
OBJECTIVE Evaluation of selective decontamination of the digestive tract (SDD) on late mortality in ventilated trauma patients in an intensive care unit (ICU). METHODS A multicenter, randomized controlled trial was undertaken in 401 trauma patients with Hospital Trauma Index-Injury Severity Score of 16 or higher. Patients were randomized to control(More)
The total weight of the normal adult human heart as well as that of each ventricle is proportional to body size. Body weight is superior to height as a predictor of total heart and isolated ventricular weights. Ventricular wall thickness is an insensitive means of assessing ventricular hypertrophy. Heart weight is a poor predictor of isolated right(More)
The purpose of this study was to evaluate the effectiveness of three 5-HT3 antagonists in routine clinical practice. The ultimate aim was to develop an antiemetic protocol, selecting a single 5-HT3 antagonist. Each of the drugs was studied for a 4-month period and data was collected from patients on nausea, vomiting (both acute and delayed) and side-effects(More)
Preliminary results of a study of the possible relationship of depot-medroxy-progesterone acetate (DMPA) to invasive cervical cancer are presented. The findings are based on data from three participating centres in Thailand and one in Mexico. A relative risk for cervical cancer of 1.2 was observed in women who had ever used DMPA; this was not statistically(More)
