Injury to the small bowel is one of the tragic complications of radiotherapy. We performed a retrospective analysis of patients operated upon for stenosis, perforation, fistulization, and chronic blood loss of the small bowel after radiotherapy for multiple malignant diseases. In the period 1970 to 1982 in the Department of General Surgery of the St.(More)
We used simple statistics (e.g. mean temperature, degree days, cumulative volume days) to describe present thermal habitats for cool water (yellow perch, Perca flavescens) and cold water (lake trout, Salvelinus namaycush) fish of a small boreal lake. We then modelled changes in the vertical and temporal extent of these habitats under various scenarios of(More)
In order to test the clinically supposed development of tolerance during chronic high-dose nitrate therapy, we studied a total of 24 patients with angiographically proven coronary heart disease at rest and during ergometric exercise (supine position, 50 w for 3 min). Pulmonary arterial pressure (PAP, floating catheter), arterial blood pressure (cuff(More)
The optimal dose of nitrates is still controversial, as chronic usage of too high a dose may result in a decrease in vascular response. The dose should be determined to reduce preload acutely, and not to decrease the activity during chronic therapy. To determine this dose, 50 patients with angiographically confirmed coronary artery disease were studied. The(More)
1. After initial acute administration of 20 or 60 mg ISDN, 2 mg molsidomine and 20 mg nifedipine, a clear effect on the circulation and an increase in work tolerance is detectable. 2. Following 4 weeks' treatment with 3 X 20 mg ISDN, there is no essential loss of action in the venous branch or with respect to working capacity. 3. After 4 weeks' treatment(More)
BACKGROUND If no in-house facilities for percutaneous transluminal coronary angioplasty (PTCA) are present, thrombolytic therapy is the treatment of choice for acute myocardial infarction (AMI). A few studies have shown benefit from rescue PTCA in patients directly admitted to centers with PTCA facilities. The obvious question arises whether patients with(More)
AIMS Adjunctive therapy with glycoprotein IIb/IIIa inhibitors has been shown to reduce ischaemic complications and improve clinical outcome in patients with primary percutaneous coronary intervention (PCI) for acute ST elevation myocardial infarction. Little is known about the use of eptifibatide in this setting. METHODS AND RESULTS One hundred and two(More)
Nine patients presenting with intracardiac masses were examined by ultrasound (US) and computed tomography (CT). Of these, 6 patients with atrial myxomas were diagnosed primarily by US, with the movement of the pedunculated tumors well visualized by this technique. The myxomas and the three solid tumors were demonstrated by CT as contrast defects following(More)
MRI appearances of laryngeal cartilages, normal or invaded by cancer, are still relatively unfamiliar to most clinicians. Twelve primary laryngeal tumors out of a series of 65 patients which have been investigated by MRI were examined postoperatively by macroscopic and microscopic sectioning of the surgical specimens. Images were obtained with a 0.6 Tesla(More)
