Even though thrombotic risks in thalassemia patients from standpoints of platelet dysfunction and coagulation factors are controversial, they are in favor of thrombosis due to thrombocytosis. From the study of 74 cases of thalassemia in children, marked thrombocytosis occurred during day 8 to 4 months during which one should be aware of the thrombosis.(More)
A prospective study was performed to verify the hemogram of 318 healthy fullterm newborn babies aged one hour to thirty days. The mean hemoglobin, hematocrit and reticulocyte count were between 17.6-17.9 g/dl, 52.2-53.4% and 5.7-6.7% in the first 72 hours of life. After that, they were decreased gradually approaching adult level at the later half of one(More)
HIV seroconversion was reported in 2 haemophiliacs after having corrective orthopaedic surgery. They received solvent-detergent/heat-treated factor VIII concentrate, HIV-seronegative cryoprecipitate and fresh frozen plasma during the course of surgery. HIV seroconversion was found on days 31 and 71 after surgery. It is highly probable that the infections(More)
Pulmonary microthromboembolism is one of the serious complications found in patients with thalassemia. The pathogenesis is undetermined. The thrombotic risk in 44 patients (26 males, 18 females) with beta-thalassemia/hemoglobin E disease and without clinical symptoms of thrombosis were studied. The age ranged from 3-19 yr (X +/- SD = 10 +/- 4). Neither of(More)
Recently there have been increasing reports of HIV infection acquired through transfusion of HIV seronegative blood in Thailand due to high incidence of HIV new infection in blood donors. Blood or blood components (BC) prepared from HIV seronegative blood donation pose significant hazards to recipients because of the risk of viremia during the "window(More)
During 1982-1992, 15 major surgical orthopedic correction (SOC) were performed in 12 hemophiliacs. There were 11 synovectomy, 2 osteotomy, 1 currettage and suture wound, 1 release of multiple joint contracture and 1 removal of pseudotumour. During 1982-1989, frozen cryoprecipitate was entirely used for replacement therapy in 5 cases who had 7 SOC. During(More)
Acquired platelet dysfunction with eosinophilia (APDE) is acquired bleeding diathesis associated with platelet dysfunction causing prolonged bleeding time. Most of them had eosinophilia. Various reports of the isolated cases had normal level of immunoglobulins but few had increased IgE. This report is different from others in that among 41 cases of APDE, it(More)
In Thailand, the anti-HIV screening in the donor blood was started in 1987 and was compulsory nationwide in February 1989. Sixty-six hemophilia A and 10 hemophilia B patients who received approximately six million units of factor VIII and IX in the form of fresh frozen plasma, frozen cryoprecipitate, cryoprecipitate removed plasma, fresh dry plasma and(More)
Retrospective analysis of childhood histiocytoses treated at the Department of Pediatrics, Ramathibodi Hospital from May 1970 till June 30, 1992 to verify the prevalence according to the recent classification, course and prognosis was conducted. Among 120 cases, 54 were Class I or Langerhan Cell Histiocytosis (LCH, previously called Histiocytosis-X).(More)
