Abstract
PDF - Systemic plasmacytosis is an uncommon disorder characterized by widely disseminated macular skin eruptions composed of polyclonal lymphoplasmacytic infiltrates associated with variable extracutaneous involvement. An aggressive clinical course has been observed in a small number of patients, but most cases have followed chronic and benign clinical course without spontaneous remission. Previously reported cases of this entity have been described almost exclusively in Japanese patients. We recently experienced a case of systemic plasmacytosis in a 48-year-old Korean female patient. Initial skin biopsy specimen revealed patchy perivascular and periadnexal infiltrates of mature plasma cells. Serum immunoelectrophoresis revealed polyclonal hypergammaglobulinemia, and polyclonal plasmacytosis was noted on the subsequent biopsy specimens of left supraclavicular and axillary lymph nodes. Multiple tiny pulmonary nodules appeared six years after the initial cutaneous presentation and were found to be of the same histologic appearance. We herein report a rare case of systemic plasmacytosis with a review of the literature.

Abstract
PDF
- The pathogenetic role of intrauterine infection to the neonatal pulmonary injury and bronchopulmonary dysplasia was assessed by studying the interleukin-6 (IL-6) level in the umbilical cord blood and the early morphologic changes of the neonatal lung. Patients were grouped into bronchopulmonary dysplasia (4 cases), chorioamnionitis without chronic lung injury (4 cases), and 6 cases without morphologic evidence of chronic lung injury or placental inflammation. IL-6 level of umbilical cord blood was higher in babies with bronchopulmonary dysplasia (17.7 pg/ml) compared to those with chorioamnionitis (4.7 pg/ml) or those with morphologically normal lung and placenta (6.2 pg/ml). Morphologic parameters of neonatal pulmonary injury were hyaline membrane, terminal bronchiole inflammation, terminal bronchiole regeneration, alveolar collapse and fibroblastic proliferation. Bronchiolar regeneration was the most peculiar feature seen in the lung with bronchopulmonary dysplasia. Alveolar collapse and interstitial fibroblastic reaction were commonly seen in bronchopulmonary dysplasia. The postnatal age at death was higher in those with bronchopulmonary dysplasia, although the occurrence of the morphologic changes was related with the chronicity of those lesions. These findings suggest that intrauterine infection is an aggravating factor for the neonatal pulmonary injury and bronchopulmonary dysplasia, although the early stage of the lung injury is not a definitive indicator for the progressive pulmonary damage leading to the bronchopulmonary dysplasia.

Abstract
PDF
- Viral myocarditis is considered an important cause of dilated cardiomyopathy. At preseent, two mechanisms are known to be involved in the pathogenesis of viral myocarditis and subse-quent cardiomyopathy: viral direct toxicity and immune mediated toxicity. Some authors have reported that IL-6 influences the immunologic mechanism and the virus-induced tissue damage in myocarditis. We injected encephalomyocarditis(EMC) virus to induce viral myocarditis in ICR mice. In order to study the lymphocyte subset and IL-6 expression to clarify the immune mechanism and to demonstrate the role of IL-6 in viral induced myocardial damage. The following results were obtained: 1) In virus inoculated mice, inflammation was severest at 10 days, and some serious complications developed, indicating a possible transition to dilated cardiomyopathy. 2) On analysis of the lymphocyte subset, CD4 cells were most prevalent at 5 days and CD8 cells were most prevalent at 10 and 20 days. 3) IL-6 was significantly increased and expression of IL-6 was constant, but its intensity was strongest at 5 days. In conclusion, IL-6, produced by inflammatory cells, fibroblasts, and endothelial cells, might play an important role in myocardial damage in experimentally induced EMC viral myocarditis by its direct cytotoxicity or cytokine mediated activation of cytotoxic cells.
