Natural history and consequences of the novel 2009 influenza A H1N1 (2009 H1N1) infection in immunocompromised pediatric patients are not yet fully understood. In this study, we investigated the clinical features and outcomes of the 2009 H1N1 infection in pediatric patients with hematological and oncological diseases. We retrospectively reviewed the medical records of 528 patients who had hematological and oncological diseases... |
Purpose : An association between idiopathic thrombocytopenic purpura (ITP) and systemic lupus erythematosus (SLE) has been recognized for decades because thrombocytopenia is the first manifestation in some patients with SLE. However, the risk of later development of SLE in childhood ITP is currently unknown. We retrospectively evaluated the incidence and clinical significance of the positive antinuclear antibody (ANA) in children... |
Purpose : The aim of this study was to investigate the incidence and course of neutropenia following intravenous immunoglobulin (IVIG) therapy in children with idiopathic thrombocytopenic purpura (ITP). Methods : From January 2001 to June 2006, fifty-four patients with ITP were enrolled in this study. Forty-two of 54 patients were treated with IVIG, while the other 12 were treated with... |
Anemia can be defined as a reduction in blood hemoglobin concentration or red cell mass relative to age matched normal values. Clinical presentation may range from obviously pale and lethargy to an incidental finding during screening of an otherwise well appearing child. The differential diagnosis of anemia in each instance is broad with numerous possible etiologies. A careful history and... |
Aplastic anemia following acute hepatitis or acute hepatic failure is an uncommon disease and has a poor prognosis. We experienced a case of aplastic anemia following acute hepatic failure in a 10- year-old girl. She was admitted because of jaundice and lethargy for 8 days. Laboratory findings revealed marked elevated serum transaminases and bilirubin levels, prolonged prothrombin time and partial... |
Shwachman-Diamond syndrome(SD syndrome) is a rare genetic disorder chracterized by pancreatic insufficiency, short stature, skeletal abnormalities and bone marrow dysfunction. Exocrine pancreatic insufficiency and neutropenia are the main components of the syndrome. A hallmark of SD syndrome is varying severity of pancreatic dysfunction due to acinar maldevelopment. The hematologic abnormalities associated with SD syndrome include varying cytopenias, marrow aplasia, myelodysplasia... |
Purpose : For the control of childhood leukemia, of which the mortality is still high, the basic data for the incidence has a great importance. The authors analyzed the data from 133 new patients with childhood leukemia between 1996-2000 in Busan, Korea. Methods : The data were obtained from 133 new cases(87 males and 46 females from 0 to 15 years... |
Purpose : We'd like to evaluate the relationship between the degree of cardiac damage and that of cardiac function according to the total injected dose of doxorubicin. Methods : 12 rabbits(body weight : 2.0-3.2 kg) were used and 30 mg/m2/week of doxorubicin hydrochloride was injected intravenously. The cardiac function was checked under anesthesia, after which the thorax was opened and cardiac samples were evaluated... |
Purpose : We evaluated plasma coagulation parameters sequentially and the influence of antithrombin Ⅲ adjuvant treatment in children with acute lymphoblastic leukemia. Methods : Twenty-nine cases with acute lymhoblastic leukemia who had been treated with L-asparaginase at Pusan National University Hospital were enrolled in this study. The coagulation parameters were checked before and on every week of L-asparaginase administration. The... |
Purpose : This study was designed to evaluate the safety and efficacy of early cessation of antibiotic treatment regardless of absolute neutrophil count in children with febrile neutropenia and no identifiable infectious source. Methods : A prospective randomized clinical trial was performed in 93 episodes of fever in 37 neutropenic children with cancer, who were admitted to the Department of... |
Purpose : Clinical and pathological prognostic factors of idiopathic IgA nephropathy have been reported, but mostly in adults and a few in children. Especially studies about correlation between those factors are very rare. Methods : We studied 58 children patients who were hospitalized to our clinics and diagnosed as IgA nephropathy by renal biopsy from Jan. 1989 to Jun 1996. They... |
Purpose : The aim of the present study was to assess the clinicopatholgical significance of Bcl-2 oncoprotein expression in childhood non-Hodgkin' s lymphoma(NHL). Methods : We have assessed 16 cases of childhood NHL during last 6 years from 1990 to 1995. Bcl-2 oncoprotein expression has been semiquantitatively analyzed in paraffin sections from 16 cases of childhood NHL with 39 control cases of adult NHL. The... |
Purpose : Endothelin-1 is the most potent vasoconstrictor. This study was investigated the correlation of plasma endothelin-1 and pulmonary hypertension associated with congenital heart defect. Methods : We evaluated the concentration of ET-1 in 24 cases of congenital heart disease diagnosed at the Department of Pediatrics, Pusan National University, from December 1993 to September 1994. The patients were divided into 2 groups according to mean... |
A case of ring 14 chromosome syndrome, confirmed by chromosome study, was dis¡ⓒ cribed. She was 15 months old and manifestated facial abnormalities containing micro¡ⓒ cephaly, flat occiput, hyperterrorism and psychomotor retardation, intractable seizure. Chromosomal study showed the ring 14 chromosome, karyotypic ally she was depicted 46, XY, r(14). A brief review of all literature was also presented. |
Eosinophilic gastroenteritis is an uncommon disorder of the stomach, small bowel, and colon, characterized by eosinophilic infiltration of the gut wall and peripheral blood eosinophilia. The clinical features depend on the site of eosinophilic infiltration. Patients with eosinophilic gastroenteritis may develop an exudative ascites containing eosinophils.

Congenital absence of spleen is often associated with malpositions and malformations of other organ system such as congenital heart disease partial situs inversus, symmetric lobulation of the liver and the lungs. This is a rare syndrome but has been reported in increasing frequency in recent years. The pure congenital asplenia is a very rare disease. We experienced two cases of congenital asplenia. One is... |
