Naloxone was given as an I.V. bolus of 0.8 mgs to four groups of patients with stroke: 1) 20 patients with C.T. proven cerebral infarcts of longer than 7 days duration; 2) 20 patients with acute cerebral ischemia of less than 24 hours; 3) 5 patients with C.T. proven intracerebral hemorrhage of less than 24 hours, and; 4) 3 patients with hyperacute cerebral ischemia which occurred during the per...

OBJECTIVES We investigated the prognostic significance of exercise-induced silent myocardial ischemia in both high and low risk men with no prior coronary heart disease (CHD). BACKGROUND Silent ischemia predicts future coronary events in patients with CHD, but there is little evidence of its prognostic significance in subjects free of CHD. METHODS We investigated the association of silent i...

The ankle-brachial index (ABI) is widely accepted as a diagnostic test used to evaluate the presence of lower extremity peripheral artery disease (PAD) in patients with symptoms of intermittent claudication or rest ischemia.1–3 However, the majority of patients with PAD are asymptomatic; therefore, measurement of the ABI only when prompted by symptoms will result in most cases of PAD going unre...

Essential thrombocytosis (ET) is a myeloproliferative disorder characterized by an anomalous increase in platelet production. Many patients with ET are asymptomatic. Few studies have reported ET-associated thromboembolism in large vessels such as the aorta. We report a patient with ET who presented with peripheral embolism from an abdominal aortic thrombus and developed acute limb ischemia. The...

A thoracic outlet syndrome (TOS) is caused by arterial or nervous obstruction because of skeletal or muscular anomalies and hypertrophies. Congenital rib anomalies occur with low incidences (0.15-0.31%), predominantly affect the right side and are normally diagnosed at a young age or remain asymptomatic throughout life. Here, we report on the unusual case of a 71-year-old female patient with su...

Endoscopy revealed pulsatile submucosal arterial vascular collaterals with nipple sign in stomach [Figure 1]. There was a small amount of fresh blood in stomach, but no active bleeding. He was treated conservatively and remained asymptomatic in follow‐up. Abdominal‐enhanced computed tomography (CT) showed dissection of the celiac trunk and enhancement perigastric and gastric intramural vascular...
