BACKGROUND Telangiectatic osteosarcoma (TOS) is a rare subtype of osteosarcoma (OS). The authors reviewed their experience with TOS to characterize its histologic, radiologic, and clinical features. METHODS The authors reviewed records, pathology material, and imaging studies from all patients with TOS who were treated between 1978 and 2005 and compared(More)
BACKGROUND The objective of this study was to prospectively evaluate dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) as an early imaging indicator of tumor histologic response to preoperative chemotherapy and as a possible prognostic factor for event-free survival (EFS) and overall survival in pediatric patients with newly diagnosed,(More)
Seven patients with infected transvenous dual chambered pacemakers have undergone removal of the device using cardiopulmonary bypass. There were four women and three men with a mean age of 58 years. Six patients had localized infection in the generator pocket (mean of 4.6 previous unsuccessful operations for surgical sterilization). Four infections were due(More)
From January 1983 to August 1987, 29 evaluable patients with high-grade osteosarcoma were treated in our institution with preoperative intra-atrial cisplatin, 100 mg/m2 every 14 days for three courses. Surgery was done on day 42. Surgery consisted of limb salvage in six, amputations in 15, and disarticulations in eight. Postoperative chemotherapy included(More)
In order to examine the prognostic value of pulmonary arterial hypertension (PAH) in patients with moderate and severe acute respiratory failure (ARF), 225 patients with ARF who had been treated with mechanical ventilation and admitted to our ICU during a 3-yr period (January, 1983 to January, 1986) were prospectively studied. All 70 (31%) patients with(More)
This study investigated gender effects on verbal and visual memory performance in normal adults (age range 18-91 years). The subjects were 140 volunteers (70 male, 70 female). Individuals in each male-female pair were matched within three years on age and two years on education. Shipley Vocabulary scores for the groups also were equivalent. Subjects were(More)
Visual recognition memory was examined in 310 normal adults (age range 18-91) and 60 patients with unilateral vascular lesions (30 right, 30 left) using the Continuous Visual Memory Test (CVMT). Significant age-related differences were found for both acquisition and delayed phases of the CVMT, with older subjects performing lower on all variables. Data from(More)
BACKGROUND Group 1 allergens elicit a specific IgE response in about 90% of grass pollen-allergic patients. The aim of this work was to study the antigenic similarity among group 1 allergens from different grasses and to develop a monoclonal antibody (MAb)-based quantitation ELISA. METHODS Twenty specific MAbs were produced from BALB/c mice immunized with(More)
