The authors had experienced 24 cases of aeromioclavicular dislocation from 1980 to 1988 at Korea university Haehwa hospital with at least 6 months follow up. They were treated by modified Phemister method. Ther were twenty-three males and one female. The ages ranged from eighteen to fifty-eight, the average was 31.6 years. The following results were obtained. 1. The most common cause of injuries was sports injury, followed by fall down and traffic accident. 2. There were twenty-two type III and type IV according to Rockwood and Green classification. 3. Duration between injury and operation were less than 1 week in 21 cases, between 1 to 2 weeks in 2 cases and more than 2 weeks in 1 case. 4. Clinical results according to Ejeskar classification were excellent in 16 cases(66.7%), good in 6 cases(25%), and acceptable in 2 cases(8.3%). 5. There were five complications : two K-wire breakage, two recurrent dislocation and one lateral end fracture of right clavicle.

BACKGROUND/AIMS: In order to determine the relationship between the HBV precore mutant and the severity of liver disease in Korea, we performed liver biopsies in patients with HBV related chronic liver disease and compared the types of mutations and histologic findings in the same liver tissue simultaneously. METHODS: HBV DNA in liver tissues was amplified by polymerase chain reaction (PCR). The precore mutants were detected by PCR-SSCP(single strand conformation polymorphism), cloning the amplified PCR products and direct sequencing for them. RESULTS: 1. HBV DNA was detected in liver tissues of 28 cases among 30 patients with PCR. And with SSCP, the most cases were mixed type infections. 2. The HBV precore mutants were found in 12 cases among the total number of 28 cases(42.9%) and all mutations were G to A change at nucleotide 1896, creating a stop codon at codon 28. However, 10 cases among 12 mutants were associated with simultaneous another mutation at different positions or regions;9 cases at core gene region, 2 cases at nucleotide 1856(C to T change at codon 15), one case at core promoter, and one case with double mutations at nucleotide 1837 and 1846 respectively. Also, all HBV precore mutants were combined with wild type HBV sequence. 3. The relationship between HBV precore mutants and HBeAg status revealed that 4 cases from 13 HBeAg positive(30.8%) and 8 from 15 HBeAg negative or Anti-Hbe positive(53.3 %) were mutants. 4. In analysis of the types of mutants and histopathological findings of liver diseases, 6 among 15 chronic active hepatitis(40.0%), all 3 cases with hepatocellular carcinoma(100,0 %), 2 among 4 asymptomatic carriers with minimal histopathologic changes(50.0%) and a case with chronic lobular heaptitis(100.0%) showed precore region mutation. CONCLUSION: The patterns of HBV precore mutants in Korea could be summarized as followings. Firstly, most of the mutations are composed of G to A change at nucleotide 1896. Secondly, the most of the mutants at nuclmtide 1896 have been associated with simultaneous mutations at core promoter, core gene, and rarely at other positions, and manifested usua'ly mixed type viremic conditions. Thirdly, although precore mutation could be occurred in asymptomatic carrier, this type of mutation might be closely related with chronic or severe liver disease. However, it needs further investigations hereafter.

Lipodystrophia centrifugalis abdominalis infantilis, an typical form of progressive lipodystrophy, is a disease mainly decribed in japanese infants. We report a case of lipodystrophia centrifugalis abdominals infantilis in Korean infant. The patient is a 2 year-old-girl with a coin sized well defined depressed lesion with surrounding redness and scaly changes in the right inguinal region. The skin from the depressed lesion revealed changes similar to those originally described by Imamura et al.

OBJECTIVE: The aim of this study was to investigate the usefulness of serum ECP as a marker of the severity of asthma and extent of airway inflammation. METHOD: We investigated 108 patients suffering from bronchial asthma, who were classified as mild intermittent(n=19), mild persistent(n=27), moderate persistent(n=42), and severe persistent(n=20) and 10 healthy controls. Atopy was defined as those who showed >2+ responses on skin prick test. Serum ECP, peripheral blood eosinophil, sputum eosinophil, and PEFR were measured on the same date and meth~acholine PC20 were determined within 2 weeks. RESULTS: Serum ECP levels were 10.1+- 2.0 ug/L in controls, and 29.1+- 23.6 ug/L in asthmatic patients. According to symptom severity, serum ECP levels were 22.9 +- 15.6 ug/L, 28. 6 +- 24.1 ug/L, 29.5 +- 22.2 ug/L, and 34.6 +- 31.2 ug/L in mild intermittent, mild persistent, moderate persistent and severe persistent asthmatic patients, respectively and there were no significant differences among four groups(p>0.05). Serum ECP levels correlated with peripheral blood eosinophil counts(r=0.48, p<0.01), but not with sputum eosinophil, PEFR, and methacholine PC20 levels. There was no significant difference in serum ECP level between atopic and non-atopic asthma(p>0.05). CONCLUSION: Single measurevment of ECP level at clinic could not represent the severity of asthma.

OBJECTIVE: We evaluated the clinical implications of serum ECP and peripheral blood eosinophil counts as indices of airway inflammation during the follow-up of asthmatics (BA). METHODS: We repeatedly measured the serum ECP, peripheral blood eosinophil counts and peak expiratory low rate (PFR) during the follow up of 24 symptomatic BA. RESULTS: Mean serum ECP level of BA at uncontrolled status of airflow limitation was significantly higher than that of controlled state (24.5i3.7 ng/ml rs. 16.2+1.9 ng/ml, p<0.05) and the ECP levels of controlled and uncontrolled status were significantly higher than that of health control subjects (n=10, 10.1+/-2.0 ng/ml, p<0.01 respectively). Pe ripheral blood eosinophils were also significantly increased in uncontrolled status than in controlled status of BA (535.7+/-81.0/1tL vs. 300.4+33.4/micro liter, p < 0.05). In controlled status, 8 BA had higher circulating ECP levels than in uncontrolled status, but with peripheral blood eosinophil counts, only 3 BA had higher levels in controlled status than in uncontrolled status. Variations of PFR correlated with the variations of serum ECP level (r=-0.5370, p<0.01) and variations of peripheral blood eosinophil count (r=-0.6215, p<0.001). CONCLUSION: Measurement of serum ECP and peripheral blood eosinophil count would be useful tools for monitoring the disease activity of asthma, but we could not obtain any more informations from the measureinert of serum ECP levels than from the peripheral blood eosinophil counts.

The authors reviewed surgical materials from 20 patients with carcinoma of the extrahepatic biliary system, and a correlation between macroscopic appearance of the tumors with various clinical features and histopathologic findings was made. Microscopically, the tumors were classified into four types; Four (21%) patients had polypoid tumors, six (32%) had nodular growths, five (26%) were scirrhous constricting in type, and four (21%) had diffusely infiltrating type. Histologically all the differentiation in two cases. The degree of differentiation of the tumors was classified into 3 types: 11 (55%) patients were well differentiated, 3(15%) were moderately well and 6(30%) were poorly differentiated. All polypoid tumors were well differentiated and had low stage. No correlation in the degree of differentiation of the tumor with the stage was present. No correlation in clinical symptoms, duration of symptoms, laboratory findings with morphologic findings of the tumors was noted.
