Abstract PDF: Hemolytic disease in a newborn that causes early jaundice is common. It is often due to the Rh (D) and ABO incompatibility, but rarely due to unexpected antibodies. Among these unexpected antibodies, the anti-Di(a) antibody rarely occurs. The anti-Di(a) antibody was observed in the serum and red-cell eluate of an infant, and in the serum of his mother. The frequency of the appearance of the Di(a) antigen in the Korean population is estimated to be 6.4-14.5%. This paper reports a case of hemolytic disease in a newborn associated with the anti-Di(a) antibody. A full-term male infant was transferred to the authors' hospital due to hyperbilirubinemia the day after his birth. The laboratory data indicated a hemoglobin value of 11.6 g/dL, a reticulocyte count of 10.6%, a total bilirubin count of 14.4 mg/dL, a direct bilirubin count of 0.6 mg/dL, and a positive result in the direct Coombs' test. Due to the identification of an irregular antibody from the maternal serum, an anti-Di(a) antibody was detected, which was also found in the eluate made from the infant's blood. The infant had been treated with phototherapy and intravenous immunoglobulin since the second day after his birth and was discharged due to an improved condition without exchange transfusion. Therefore, in cases of iso-immune hemolytic disease in a newborn within 24 hours from birth who had a negative result in an antibody screening test, the conduct of an anti-Di(a) antibody identification test is recommended due to the suspicion of an anti-Di(a) antigen, followed by early administration of intravenous immunoglobulin.

Abstract PDF: BACKGROUND
As Mycoplasma pneumoniae pneumonia has increased in Korea, its relevance to infants, toddlers, and adolescents has magnified as well as. However, it is difficult to perform the serological test and PCR test routinely for diagnosis in actual clinical practice. Thus, the authors conducted this study to help clinicians do presumptive diagnosis of Mycoplasma pneumoniae pneumonia using clinical, radiological, and hematological findings. METHODS: The study population consisted of 224 children between 1 month and 14 years old, hospitalized for radiographically confirmed pneumonia. Patients were divided into two groups of 100 children with Mycoplasma pneumoniae pneumonia, as diagnosed using the ELISA method. Groups with negative result in Mycoplasma IgM antibody test were classified into the viral group (98 patients with respiratory virus) and the bacterial group (46 patients with the bacteria detected in the blood sputum culture or antibiotic treatment except macrolide improved the patient's condition). These groups were compared and analyzed using clinical, hematological,and radiographic differences and scoring system. RESULTS: Clinical, hematological, and radiographic characteristics of Mycoplasma pneumoniae pneumonia have shown the intermediate level results between bacterial pneumonia and viral pneumonia. In terms of scoring system, the mean score of Mycoplasma pneumoniae pneumonia was 4.23, which was the intermediate level between bacterial pneumonia (mean score=6.67) and viral pneumonia (mean score=1.48). CONCLUSION: Results suggest that the combination of the scoring system information can increase the accuracy in the diagnosis even if they may have difficulties on diagnosis, because clinical manifestations, hematological, and radiographic findings are nonspecific.

A Case of Superior Mesenteric Venous Thrombosis after Endoscopic Sclerotherapy.: Won Duck Kim, Kwang Hae Choi, Jeong Ok Hah; Yeungnam Univ J Med. 2001;18(2):297-301. Published online December 31, 2001; DOI: https://doi.org/10.12701/yujm.2001.18.2.297

Abstract PDF: The efficacy of injection sclerotherapy for treatment of acute esophageal variceal bleeding is well established. But several complications of endoscopic sclerotherapy have been reported. One of the complications is mesenteric venous thrombosis which develops when vasopressin is user for the sclerotherapy. We report a case of superior mesenteric venous thrombosis with developed after endoscopic sclerotherapy for control of esophageal variceal bleeding.

Abstract PDF: We report the result of a high-dose intravenous immunoglobulin therapy in a Henoch-Sch?nlein purpura patient with severe abdominal pain and nephrotic syndrom who did not respond to methylprednisolone pulse therapy. Kidney bbiopsy showed diffuse mesangial cell proliferative glomerulonephritis with fibrocellular crescent formation in approximately 50% of glomeruli. Mesangium of all glomeruli were strong positive for IgA and C3 antibodies. High-dose intravenous immunoglobulin treatment was introduced and dramatic improvement of gastrointestinal symptom and proteinuria as well as hematuria was noted. Immunoglobulin administration should be considered in Henoch-Schnlein purpura patients with sterois-resistant intractable dastrointestinal manifestation and renal involvenment.

Abstract PDF: BACKGROUND
Acute idiopathic thrombocytopenic purpura(ITP) is one of the common hematologic disorders in children. Bone marrow aspiration(BMA) is often performed in children with acute ITP to rule out leukemia, aplastic anemia or other hematologic diseases. However, whether BMA is needed in children with typical clinical and hematological features of acute ITP have been questioned. This study was performed to examine the proper indication of BMA in acute childhood ITP. MATERIALS AND METHODS: The medical records and BMA reports of children with the provisional diagnosis of acute ITP were reviewed from January 1984 to December 2000. Patients were divided into two groups, one with typical and another with atypical clinical and hematological features of acute ITP. Typical acute ITP group was characterized by the history of previous viral infection, well being appearance, no hepatosplenomegaly, no lymphadenopathy, normal Hb, WBC, neutrophil count and peripheral blood smear except thrombocytopenia. A platelet count of 50x109/L or lower was the cutoff level. RESULTS: Total 120 children with the provisional diagnosis of acute ITP were included. One hundred eighteen of them were confirmed to have acute ITP by BMAs. Of these, 66 had typical and 54 had atypical features. All of typical features and 52 of 54 with atypical features of acute ITP were confirmed to have acute ITP by BMAs. Two patients with atypical features of acute ITP were diagnosed as aplastic anemia and myelodyspalstic syndrome, respectively, by BMAs. CONCLUSION: This study concludes that BMA is not needed for the children with typical features of acute ITP but it is needed for the children with atypical features of acute ITP to rule out other hematologic disorders.
