Surface ECG findings in 29 patients with left isomerism were reviewed. Among the total 46 wave axis distributions, 25(54%) were abnormal axis, not originated from sinus node. Congenital atrioventricular block was found in 2 children. 6 patients showed the bradycardia and junctional escape rhythm intermittently or persistently. 4 of them, not related with heart surgery, were much older than 2 patients who showed these ECG findings after heart surgery. These ECG findings suggested the possibility of occurrence of sinus node or subsidiary pacemaker dysfunction in the patients with left isomerism, especially in the older patients. So we thought that electrophysiologic evaluation is necessary in some patients with left isomerism.

Pneumocystis carinii is a pulmonary pathogen of immunocompromised humans or other mammals. Its infection results from activation of organisms involved in latent infection or from new infection through the air. Almost all children are known to be infected within 2 to 4 years of birth, though prenatal transplacental transmission has not yet been demonstrated. In this study we observed experimental P. carinii infection in neonatal rats, thus investigating the possibility of transplacental vertical transmission by Diff-Quik staining of the lung impression smears and in-situ hybridization for lung sections. The positive rate of P. carinii infection in immunosuppressed maternal rats was 100%, but that in normal maternal rats was 0%. Cystic forms of P. carinii were observed in three of six 1-week old neonatal rats born of heavily infected mothers, but none of them was positive by in-situ hybridization. Five weeks after birth, cystic forms were detected in four neonatal rats. In the lobes of the lungs, no predilection site of P. carinii was recognized. Counts of cystic forms on smears and the reactivity of in-situ hybridization in the lungs of neonatal rats were significantly lower than in maternal rats. The present findings suggest that P. carinii is rarely transmitted through the placenta and proliferates less successfully in the lungs of neonatal rats than in mothers.

Allogenic peripheral blood stem cell transplantation could be used instead of allogenic bone marrow in treatment of leukemia in children. This 10-year-old female patient with high-risk acute lymphoblastic leukemia received a myeloablative regimen followed by allogenic peripheral blood stem cell transplantation from an HI A-identical sibling donor. Neutrophil recovery to greater than 500/pL occurred at day 11 and platelets recovered to greater than 20,000/pL at day 13. Allogenic peripheral blood stem cell transplantation can be performed safely and may result in a rapid neutrophil and platelet engraftment, without any apparent increased risk of acute graft versus host disease.

A case of Aicardi syndrome with cleft lip and palate was experienced at the Department of Pediatrics, College of Medicine, Hallym University, and the patient's infantile spasm was treated with ACTH. In previous studies, four cases of Aicardi syndrome accompanied by cleft lip and palate were reported. We present the fifth case of Aicardi syndrome with cleft lip and palate in the world. Thus, facial clefts may be found as an occasional manifestation of Aicardi syndrome.

BACKGROUND: CD44 protein is known as a homing cellular adhesion molecule that is linked to diverse cellular functions such as adhesion, migration and invasion, which are all important in cancer progression and metastasis. The expression of CD44 standard and variant isoforms (CD44 standard isoform [CD44s] and CD44 splice variants containing exon v6 [CD44v6], respectively) is associated with an unfavorable clinical outcome in various neoplasms. METHODS: Forty patients who were diagnosed with diffuse large B-cell lymphoma (DLBCL) through biopsy at Hanyang University Hospital between 1996 and 2003 were included in this study. CD44 proteins expression was analyzed by immunohistochemical staining on a tissue microarray and the correlation of CD44 with the types of DLBCL and clinical parameters, including the factors defined by the International Prognostic Index, was evaluated. RESULTS: A high CD44s and intermediate to strong CD44v6 expression, including cytoplasmic membranous staining patterns, was present in 35% (14/40) and 25% (10/40) of DLBCL patients, respectively. High CD44s expression was correlated significantly with non-germinal center B-cell-like types (non-GCB, p=0.004) and patients with old age (p=0.041). CONCLUSIONS: High CD44s expression may be significantly associated with the non-GCB type compared to the GCB type and may be essential to the prediction of disease outcome in tumor stage III in DLBCL patients.
