Fifty-two patients with suspected coronary artery disease underwent coronary angiography, thallium-201 myocardial imaging, and ECG-gated blood pool ventriculography at rest and at maximal exercise. In 11 patients without coronary artery disease, all thallium images were normal. The resting ejection fraction (EF) was normal in all 11 patients and increased during exercise in six, was unchanged i...

BACKGROUND Reye's syndrome is characterized by encephalopathy and fatty degeneration of the liver, usually after influenza or varicella. Beginning in 1980, warnings were issued about the use of salicylates in children with those viral infections because of the risk of Reye's syndrome. METHODS To describe the pattern of Reye's syndrome in the United States, characteristics of the patients, and...

Poverty persists in many sectors of society. Choosing no one, it creates a dent in an inclusive approach to development the Philippines has endeavored in the last few decades. To make it worse, high poverty incidence is apparent in the agriculture sector, which, together with the manufacturing industry, serves as backbone of the Philippine economy. Exposed to a multitude of risks, a considerabl...

41 patients with trauma to the urinary bladder are reviewed. 70 percent were injured as a result of blunt trauma and 63 percent of patients had an associated fracture of the pelvis. 82 percent of extra peritoneal ruptures were associated with fracture of the pelvis. the most common cause of trauma was car accident (56 percent), followed bywar injury (25 percent). the incidence of intra and extr...

Objective: We aimed to determine the effectiveness of team-based reporting, systems analysis, and redesign to address medical errors in pediatric ambulatory care. Methods: Voluntary, anonymous, nonpunitive reporting, paired with a team-based system analysis and change implementation, was established in an outpatient pediatric department of an urban teaching hospital. Results: In the first year,...

OBJECTIVES Previous studies have shown that female patients with cystic fibrosis (CF) have a significantly poorer prognosis than male patients. Such studies investigating gender-related differences have generally combined data from several centers. The aim of this study was to determine whether with modern aggressive treatment of CF this is still true when care is standardized within a single c...

We evaluated the effectiveness of high dose rate (HDR) endobronchial irradiation for palliation of malignant airway obstruction. Between May 1989 and February 1992, 39 patients were treated in our department. Thirty-two patients (82 percent) had primary lung neoplasms and 7 (18 percent) had metastatic disease. Thirty-three patients (85 percent) had prior external irradiation (either alone or in...

The real and imaginary part of the vacuum polarisation function Π(q2) induced by a massive quark is calculated in perturbative QCD up to order αs. The method is described and the results are presented. This extends the calculation by Källén and Sabry from two to three loops. The complete postscript file of this preprint, including figures, is available via anonymous ftp at ttpux2.physik.uni-kar...
