Forty one cases of Hodgkin's disease and non-Hodgkin's lymphomas were immunohisto-chemi-cally studied for the presence of CD30 antigen on the paraffin embedded formaldehyde fixed tissue by using Ber H2(CD30) monoclonal antibody (Dakopatts, diluted l : 20) and avidin biotin peroxidase complex technique seventy five %(6/8) of Hodgkin's lymphoma and 27% (9/33) of non-Hodgkin's lymphomas were CD30 positive. Five of l7 diffuse large cell and immunoblastic lymphoma and one large cell anaplastic lymphoma showed large numbers of CD30 positive cells. Occasional CD30 positive cells were found in one of 2 angiommunoblastic lymphadenopathy-like T cell lymphoma, one of 4 small lymphocytic lymphoma and one unclassified lymphoma. Immunophenotypically l6% of B cell lymphoma and 42% of T cell lymphoma showed CD30 positivity. six cases of Hodgkin's disease except lymphocyte predominance showed positive tumor cells. Our results show that CD30 is more widespread in histologic subtypes of lymphomas and is not specific for the diagnosis of Hodgkin's disease.

A rare case of uterine lipoleiomyoma is reported with presentation of computed tomography, histomorphologic and immunohistochemical findings. This tumor is predominantly lipomatous with an admixture of smooth muscle fiber and hyalinized fibrous tissue. Immunohistochemical study revealed a positive reaction of S-100 protein in fat cells and desmin in smooth muscle fibers. Its histogenesis also has been discussed.

Inflammatory pseudotumor of the Aver is a rare benign lesion that usually has been discovered at laparotomy. This lesion is inflamrhatory and reactive, but the etiology remains unknown. In-flammatory pseudotumor of the liver is of the interest not only because of its rarity also because it needs to be clinically differentiated from hepatocellular carcinoma and other malignant tu-mors. In this report, we describe a case of inflammatory pseudotumor of the liver with fever and weight loss in a 46-year-old male. Grossly, the lesion showed a rather well demarcated, gray white to pale yellowish nodular mass mesuring 7 x 5.5 x 5 cm in dimensions. M icroscqpically, the tumor was composed of diffuse infiltration of predominantly plasma cells, lymphocytes and histocytes associated with fibroblastic proliferation.

PURPOSE: The increased prevalence and incidence of end-stage renal disease (ESRD) in the elderly has become a worldwide phenomenon. New cases of ESRD are growing faster among people aged older than 70 years. We studied in order to investigate the survival rate, technical survival rate, causes of death and the predictors of death in patient starting hemodialysis aged over 70 years. METHODS: We analyze 34 patients who started hemodialysis as an initial replacement therapy for chronic renal failure in Kangnung Asan Hospital between July 1996 and July 2001. Demographic and clinical characteristics, including diabetes mellitus and laboratory findings at the beginning of hemodialysis were retrospectively analyzed. All subjects were followed up until the point of assessment, the time of death or withdrawal from dialysis. The survival rate was calculated by Kaplan-Meier method. In order to determine independent predictors of death, we used Cox proportional hazard model. RESULTS: The median age of the patients was 74.5 years and sex ratio was 2.4:1 (M:F). The most common cause of ESRD was diabetes (35.5%) and obstructive uropathy was second. The mean follow-up period was 18.6+/-2.5 months and cardiac problems were major causes of death (37.5%). The survival rate of 34 patients was 84.9% at 1 year, 72.8% at 2 year and 56.6% at 5 years. The technical survival rate of 34 patients was 54.7% at 1 year, 48.6% at 2 year and 30.1% at 4 years. The predictors of death were found to be (i) age starting hemodialysis (RR=1.685, p=0.018) (ii) female (RR=18.5, p=0.028) (iii) low initial hemoglobin level (RR 0.233, p=0.009). CONCLUSION: Very elderly ESRD patients on dialysis have a relatively good outcome and age is not barrier to dialysis. Measures to improve quality of life of elderly hemodialysis patients may favorably influence their survival.

The complications of the treatment of penile lesion are wide ranging, urethrocutaneous fistula being one of the less common. This complication affects the ventral aspect of the penis. We present a rare case of urethrocutaneous fistula after vaporization of penile lesion by CO2 Laser. One fistula was at ventral aspect of the penis. A 43-year-old male presented with passage of urine from one opening. He had undergone a vaporization by CO2 laser, 2 times. Urethrocutaneous fistula repairs was performed with biopsy of the edge of fistula site. Squamous cell carcinoma was confirmed. He subsequently underwent a partial penectomy. It is very important that biopsy was performed before vaporization of even small size skin lesion. This case is reported along with a brief review of the literature.

PURPOSE: Throat culture for streptococcal pharyngitis is a gold standard to diagnose, but it may be misleading to interpret due to the carriers. The isolation rates of beta-hemolytic streptococci (BHS) and Streptococcus pyogenes in the school children in Chinju were investigated and compared with those of Kangwon, Chungnam and Seoul previously reported. METHODS: Throat cultures were taken from the healthy 476 elementary school children who had no symptoms or signs of upper respiratory tract infection in April 1995, and the beta-hemolytic streptococci were identified with bacitracin disk (0.04 U) and latex agglutination. RESULTS: One-hundred fifty-four (32.4%) yielded BHS and 88 (18.5%) had S. pyogenes. The serogrouping revealed 30 (6.7%) group G, 24 (5.0%) group C, 4 (0.8%) group B, and 8 (1.7%) non-group A,B,C,G respectively. CONCLUSIONS: The isolation rate of BHS in Chinju was significantly higher (p<0.001) than the results of Kangwon, Chungnam and Seoul. The identification of BHS was also different from the other areas. In addition to these bacteriologic investigation, the study should be followed whether these carriers were simple contact ones or suffered from asymptomatic infections, and the epidemiologic study using serotyping, such as M or T typing, is necessary.

Gastric volvulus is an uncommon condition which is difficult to diagnose and treat. It designates abnormal rotation of the stomach along its longitudinal (organoaxial) or transverse (mesenteroaxial) axis. When the rotation exceeds 180 degrees, gastric obstruction or strangulation may occur. The classical presentation of acute gastric volvulus is the triad of severe epigastric pain, vomiting followed by retching without the ability to vomit, and difficulty or inability to pass a nasogastric tube. Delay in diagnosis and treatment of gastric volvulus can lead to fatal complications such as gastric ischemia, perforation, and hemorrhage. Gastric volvulus is a true emergency which should be treated immediately either surgically or by upper endoscopy. We report a case of an acute incarcerated gastric volvulus due to a left-sided diaphragmatic hernia in an adult male patient, which was treated successfully by operation.

BACKGROUND: Korea is one of high incidence areas of Hepatocellular carcinoma (HCC) and major etiologic factor is hepatitis B virus (HBV). In future incidence of HBV related HCC may decrease and non viral hepatitis HCC (Non-B,C HCC) relatively increase because of widely used vaccination for HBV. To evaluate epidemiological characters of Non-B,C HCC, We divided HCC by viral or non-viral feature and compared each others. METHODS: 185 patients firstly diagnosed HCC and 455 normal subjects included from January 1997 to December 2000 and divided into 3 groups, HBV group (positive HBsAg), HCV group (positive anti-HCV Ab) and Non-B,C group (both negative HBsAg and anti-HCV Ab). RESULTS: 136 cases were HBV group (73.5%), 19 cases were HCV group (10.3%) and 27 cases were Non-B,C group (14.6%). Mean age of Non-B,C group at diagnosis was higher than HBV group (64.1+/-7.1 vs 55.6+/-7.7). Non-B,C HCC were more associated with alcohol abuse and rural residence (p<0.01). There was no difference of family history of liver disease, coexistence rate of liver cirrhosis and occupation. CONCLUSION: Non-B,C HCC tended to be older in mean age than HBV HCC and more associated with alcohol abuse and rural residence. This characteristics of Non-B,C HCC supposed to be from difference in alcohol consumption and environment.

Purpose: This study evaluates the prognostic significance of tumor size at disease progression (PD) and depth of response (DOR) in cancer patients. Materials and Methods: We performed post hoc analysis using data from six prospective clinical trials conducted by the Korean Cancer Study Group. Patients with tumor size at PD was categorized into ‘Mild PD’ and ‘Significant PD’ based on the cutoff values of relative change from baseline using maximally selected rank statistics. The overall survival (OS) and progression-free survival (PFS) were compared between PD and DOR categories. Results: Among the 194 evaluable patients, 130 experienced PD. A 35.48% decrease from baseline in tumor size at PD was chosen for the cutoff between mild and significant PD for OS (mild PD: tumor size from the baseline ≤ −35.48%; significant PD > −35.48%). The mild PD had superior OS compared to the significant PD (25.8 vs. 12.8 months; Hazard ratio [HR] 0.47, 95% CI 0.266-0.843, p=0.009). When using an exploratory cutoff based on whether the tumor size was below vs. exceeded from the baseline (mild PD: tumor size from the baseline ≤ 0%; significant PD > 0%), OS remained significantly longer in the mild PD (17.1 vs. 11.8 months; HR 0.60, 95% CI 0.392-0.932, p=0.021). The greatest DOR was associated with the longest OS and PFS (p<0.001 for both). Conclusion Tumor size at PD and DOR were significant prognostic factors for progressive disease. Maintaining a sufficiently reduced tumor size even during PD was associated with better survival outcomes.
