The effect of epilepsy and anti-epileptic treatment on neonatal outcome was investigated in 86 pregnancies terminating in delivery. Various maternal and neonatal parameters were considered. Each infant born to an epileptic mother was double-matched with two infants born to healthy mothers and the results were submitted for statistical analysis. Infants of(More)
Current flow-based blood counting devices require significant medical infrastructure and are not appropriate for field use. In this article we report on the development of a sample preparation, measurement, and analysis method that permits automated and accurate counting of red blood cells (RBCs), white blood cells (WBCs), and platelets, as well as allowing(More)
Potential sources of stress and satisfaction as perceived by direct-care staff members in community residences for mentally retarded adults were investigated. Results indicated that stress and satisfaction are not polar opposites but two largely separate dimensions of workers' experiences. In addition, sources of satisfaction and stress had two components,(More)
Immunologic studies demonstrate that non-Hodgkin's lymphomas are derived predominantly from B- or T-lymphoid cells, while node-based tumors of true histiocytic derivation are rare, with few documented cases. This report describes the clinical, histologic, immunohistochemical, and ultrastructural features of two cases of node-based true histiocytic lymphoma.(More)
UNLABELLED We performed this study in an attempt to reconcile the differences with respect to 67Ga uptake as a function of tumor grade and type in the literature, as well as to determine the sensitivity of 201Tl uptake in both Hodgkin's and non-Hodgkin's lymphoma. METHODS Thirty-six (9 with low-grade lymphoma, 11 with intermediate-grade lymphoma, 4 with(More)
Ninety patients with Stage I or II, including extranodal (E), presentations of non-Hodkin's lymphoma were investigated by laparotomy, either for the definitive staging of patients with peripheral presentations or for diagnosis of abdominal disease. Sixty-eight patients had staging laparotomies after extensive work-up, which included lymphangiography and(More)
Cystadenocarcinoma of the pancreas is generally considered to be unresponsive to chemotherapy and radiation therapy. We present two cases of laparotomy-proven unresectable cystadenocarcinoma which responded to intravenous 5-fluorouracil (1,000 mg/m2/24 hr x 5 days x 2) and 4,000 rads of radiation therapy. Both patients had objective response with marked(More)
Ninety-five families who had completed a 20-week behavioral-training program for parents of retarded children (Heifetz, 1977) were re-contacted 14 months later. An in-home interview and several questionnaires assessed maintenance of child gains and parents' knowledge of programming principles, as well as the extent and quality of continued and new(More)
The penetration of oral cefixime into the synovial fluids of 16 patients (mean age, 50.6 years) who underwent joint taps for rheumatic noninfectious disorders was examined. The patients were each given a single dose (400 mg) 2 to 24 h prior to the tap. Cefixime concentrations in serum and joint fluid samples were measured by high-performance liquid(More)
