To define the clinical significance of exercise-induced ST-segment elevation, exercise thallium-201 scintigraphy (Ex-Tl), left ventriculography and coronary arteriography were performed in 19 patients with anterior infarction less than 3 months previously. Seven of the 19 patients showed redistribution by Ex-Tl and underwent percutaneous transluminal coronary angioplasty (PTCA). In these 7 pati...

segmental defects of the tibia are challenging therapeutic problems for both the physician and the patient. these defects may be caused by severe trauma, infection, tumors and congenital processes. several different techniques have been described for treatment of these defects including the papineau technique, allograft reconstruction, bone transport using the ilizarov frame, free vascularized ...

OBJECTIVES The goal of this study was to determine, in patients with a recent myocardial infarction (MI) and residual wall motion abnormalities within the distribution of the infarct-related artery, whether normal perfusion by myocardial contrast echocardiography (MCE) would accurately predict recovery of segmental left ventricular (LV) function. BACKGROUND Left ventricular dysfunction after ...

BACKGROUND Infarct size is a strong predictor of mortality and major adverse cardiovascular events after myocardial infarction. Acute reperfusion therapy limits infarct size and improves survival, but its use has been confined to patients with ST-segment-elevation myocardial infarction. The purpose of this study was to assess the relationship between echocardiographic parameters of left ventric...

ted with a 1-day history of abdominal pain on the right side. Results of abdominal computed tomography done at another hospital the evening before were normal. The patient also had anorexia, nausea, vomiting and diarrhea, and she smoked. Three months earlier she had had a myocardial infarction treated by percutaneous transluminal coronary angioplasty and insertion of a stent. One month later ec...

AIM Successful primary PTCA (with TIMI 3 reflow) in patients with acute transmural infarction has been observed to result in an immediate abnormal increase in wall thickness associated with persisting abnormal post-systolic thickening. To understand the sequential changes in regional deformation during: (i) the development of acute transmural infarction, (ii) upon TIMI grade 3 infarct reperfusi...

background: segmental vitiligo is a small subset albeit persistent form of focal vitiligo with dermatomal distribution and resistant to medical therapy. in recent years, surgical therapy as hair follicle autograft transplantation has been a hot topic in management of segmental vitiligo. in this study, we evaluated the efficacy of this method in segmental vitiligo lesions. methods: the study rec...

Segmentat Middle Cerebral Artery Occlusion in Primates: An Experimental Method Requiring Minimal Surgery and Anesthesia • Due to certain anthropomorphic features of the cerebral circulation, monkeys are generally preferable to lower species in experimental models of stroke. By injecting specially molded silicone cylinders through internal carotid artery cannulas, segmental occlusions of the mid...

Mesenteric cysts are rare abdominal tumors. About 60% of these cysts occurs before 5 years of age and can be located anywhere in the gastrointestinal tract, but are most often found in the small bowel mesentery. The clinical presentation depends on the location and size of the cyst and many cases are asymptomatic and are diagnosed incidentally. The most common symptoms are abdominal pain, bloat...
