The pulmonary cavernous hemangioma is usually from birth and there may be without symptoms until adulthood. Larger or multiple pulmonary angiomata with considerable pulmonary arteriovenous shunts may cause cyanosis, finger clubbing, dyspnea and frequently accompanyingbruit. Recently, we experienced a case of cavernous hemangioma of the lung. A 34-year-old woman was admitted to our hospital for surgical evaluation of a 4 cm solitary, round nodule in the right upper lobe on the chest X-ray and CT scan. She had no symptoms. Laboratory findings are within normal limits except for elevated glucose levels. At surgery, the mass was well encapsulated and easily excised from the peripheral portion of the posterior segment of the right upper lobe. Grossly, it consisted of a 4 cm in diameter, round, soft, sponge-like, hemorrhagic, slightly lobulated mass with a smooth external surface. Microscopically, the mass was composed of vessels, which were thin walled, dilated and filled with blood. The wall of the abnormal vessels was thin and composed of endothelium and fibrous connective tissue with only a little smooth muscle. Immunohistochemically, the wall of the dilated abnormal vessesls showed negative reaction for cytokeratin(low and high) and epithelial membrane antigen but weakly positive reaction for UEA-1 in focal areas.

BACKGROUND: Several studies have demonstrated that quantitation of hepatitis B virus (HBV) DNA in sera of HBsAg-positive patients is more useful test for the assessment of infectivity and for the evaluation of disease status than previously utilized numerous serological markers and qualitative polymerase chain reaction for the detection of HBV DNA. We tried to measure serum HBV DNA using a branched DNA (bDNA) signal amplification assay, which is recently introduced and known to be a simple and nonradioisotopic method. METHODS: Total forty patients with HBsAg were randomly selected and serum HBV DNA was measured with duplication using bDNA signal amplification assay (QUANTIPLEXTM HBV DNA ASSAY, Chiron, USA). Quantitation was determined from a standard curve and expressed as HBV DNA equivalents/mL (Eq/mL; 1 Eq = 1 molecule of the primary HBV DNA standard). Serum HBeAg, aspartate aminotransferase (AST), alanine aminotransferase (ALT) , and soluble interleukin-2 receptor (sIL-2R) were compared with HBV DNA. RESULTS: Serum HBV DNA was quantitated in 13 patients (32.5%) (range 6.4x106-7.4x109 Eq/mL, mean 1.8x109 Eq/mL, CV 8.1%). All eleven patients (100%) with both HBsAg and HBeAg an4 2 of 29 patients (6.9%) with HBsAg but not with HBeAg showed measurable HBV DNA (p < 0.001). In addition, serum levels of AST, ALT, and sIL-2R were significantly higher in HBV DNA measured patients compared with those of unmeasured patients. CONCLUSIONS: Above results show that more than half the HBsAg-positive patients do not have enough HBV DNA which is measurable with boNA signal amplification assay but all of HBeAg-positive patients and some of HBeAg-negative patients do. In addition, HBV DNA quantitation might be correlated with the disease activity in HBsAg-positive patients because serum levels of AST, ALT, and sIL-2R are higher in patients measured with HBV DNA than unmeasured.

BACKGROUND: T cell mediated immune destruction is an important mechanism of liver injury in patients with chronic hepatitis C. Serum levels of soluble interleukin-2 receptor(sIL-2R) seem to serve as a marker for the T cell activation and progressive liver injury, This study examined serum levels of sIft-2R and hepatitis C virus (HCV) RNA in patients with chronic HCV infection to determine the correlation with the severity of chronic hepatocellular damage. METHODS: Serum levels of sIft-2R in 73 patients with HCV infection (chronic hepatitis 52, liver cirrhosis 9, hepatocellular carcinoma 12) and 40 healthy controls were measured by sandwich enzyme immunoassay (CELLFREE, T Cell Sciences, USA). HCV RNA was quantified by QUANTIPLEX(TM) HCV RNA 2.0 assay (Chiron, USA) with duplication. This assay is a sandwich nucleic acid hybridization procedure using branched DNA amplification for the quantitation of HCV RNA. RESULTS: The sIL-2R levels of 52 patients with chronic hepatitis (591.4+/-238.7U/mL), 9 with liver cirrhosis(949.4+/-721.9 U/mL), and 12 with hepatocellular carcinoma (1,167.4+/- 554.4 U/mL) were significantly higher than those of healthy controls(370.8+/-71.8 U/mL) (p<0.001). A progressive and significant increase occurred in sIL-2R levels with chronic hepatitis C, liver cirrhosis and hepatocellular carcinoma (HCC) in order (p(0.001). The HCV RNA was detected in all patients and the means of HCV viral load were 3.3 MEq/mL in chronic hepatitis, 2.8 MEq/mL in cirrhosis, and 3.7 MEq/mL in HCC. There was no significant correlation between HCV RNA and the severity of liver injury in chronic HCV infection. There were no correlations among sIL-2R, HCV RNA and serum ALT. CONCLUSIONS: These results suggest that chronic hepatocellular injury by HCV progress mainly by T cell mediated immune response, not by direct cytopathic injury. Also, sIL-2R can be useful as a marker in monitoring the patients with HCV infection at high risk of getting HCC.

Eosinophilic granuloma of the lung, first described by Farrinaci et al. in 1951, is rare. A 35-year-old male smoker presented with recurrent pneumothorax. Open thoracotomy with bleb resection and biopsy was performed. Microscopically there was histological changes consistent with typical eosinophilic granuloma and intertitial fibrosis. The Langerhans cells showed positive reaction for S-100 protein and typical Birbeck granules in their cytoplasm. A brief summary of histopathological aspect of this disease and a review of literature are presented.

Metaphyseal Chondrodysplasia is rare, hereditary disease characterized by defective enchondral bone formation with major manifestation at the metaphysis. Jansen originally used the term metaphyseal dysostosis in 1934 to describe a patient who has a short stature with irregular metaphysis of the lower extremity and hands. Schmid reported a milder form of Metaphyseal dysostosis in 1949, which is more common and is transmitted in autosomal dominant trait. Mukusick reported another form of Metaphyseal Chondrodysplasia which is associated with ectodermal abnormalities in 1964. The other different types were reported alos, but they are extremly rare. The basic defect in the disease may be the failure of hypertrophic cells to mature and degenerate, caused by a block in or deficiency of enzymes of glycolytic cycle. The skull and spine are spared. Serum chemistry and kidney function are normal. The only treatment necessary, once adequate diagnosis has been estabilished, is careful observation and properly timed corrective orthopaedic surgery. We experienced one case of Schmid Type Metaphyseal Chondrodysplasia. Corrective osteotomy was performed and satisfactory result was obtained.

Twenty-four cases of complete acromioclavicular dislocation had been treated surgically by Weaver and Dunn method at Hanil Hospital during the period from March 1976 to March 1988. Among twenty-four cases, we had average 84.4 months follow-up data on fifteen cases with acute complete dislocation and two cases with chronic complete dislocation. The following results were obtained. 1. The transferred coracoacromial ligament had been secured to the resected clavicular end by wire or silk(silk in eleven cases, wire in six). All patients in wire sutured group had to be reoperated on because of breakage of wire. But no significat differences in final clinical function of the shoulder was seen. 2. Calcification was found in the region of the transferred coracoacromial ligament in twelve cases(70.6%). 3. All patients had normal shoulder motion, sixateen(94.1%) were asymptomatic, and only four(23.5%) felt mild weakness of shoulder. 4. On the clinical assessment by the criteria of Imatani et. al., 12 patients(70.6%) were graded excellent, 4 patients(23.5%) were good, and one patient(5.9%) was fair.
