Pathological lesions in and around a joint can arise from underlying dermis, subcutis, deep muscle, bone or synovium. Clinical presentation can include joint pain, joint swelling, palpable masses and mechanical restriction. Whilst giant cell tumour of tendon sheath, pigmented villonodular synovitis, synovial chondromatosis, lipoma arborescens, juxta articular myxomas and inflammatory arthritis are the better-known conditions of the joint. Intra-articular nodular fasciitis, on the other hand, is less well recognized both clinically and radiologically. It is rarely seen in routine practice and is only described in case reports in the literature. Due to the non-specific clinical and radiological findings as well as the unfamiliarity with the entity, the diagnosis of intra-articular nodular fasciitis is usually clinched only after histological examination. We present a case of intra-articular nodular fasciitis arising in the knee joint which was not suspected clinically or radiologically

Primary pyogenic psoas abscess is rare lesion, and often is not suspected. Reasons for delayed diagnosis are unfamility with the lesion and the fact that symptoms often resemble those of primary disease of the hip. We present a case of primary pyogenic psoas abscess in child, which was diagnosed by MRI, and completely recovered after surgical treatment.

Cytologic findings from five cases with variable types of Hodgkin' disease were reviewed with special emphasis on the Reed-Sternberg (R-S) cells and their variants. Typical R-S and Hodgkin's cells were mono- or binucleated, and nuclei had rounded smooth contour. Acidophilic prominent nucleoli with perinucleolar halo were conspicuous. In comparison to typical Reed-Sternberg cells, L & H (lymphocytic and histiocytic) cells in the lymphocyte predominant type tended to show pop-corn like irregular nuclear contour and to lack the prominent nucleoli. Lacunar cells in the nodular sclerosis type had multilobated nuclei with prominent acidophilic nucleoli. There was no prominent perinucleolar halo in L & H and lacunar cells. In conjuction with the number of Reed-Sternberg cells and back ground findings observed on the smears, the characteristic features of R-S cells and their variants allowed to make typing of Hodgkin's disease.

PURPOSE: Epstein-Barr virus(EBV) exists in the human population in two genetic forms, usually referred to as type 1 and type 2 which have been defined on the basis of sequence divergence in the EBNA-2 and EBNA-3 family genes. In this study, we were intended to investigate whether the subtypes of EBV in malignant lymphoma in Korea were associated with specific disease entities and geographical distribution. MATERIALS AND METHODS: Biopsy samples obtained from 18 Korean patients with malignant lymphoma including Hodgkin's disease(3 cases), B cell lymphoma(1 case), and NK/T cell lymphoma(14 cases) were analyzed to determine the subtype of EBV infected therein. DNA was extracted from formalin-fixed, paraffin-embeded tissues by ordinary method and specific viral sequences were sought using the polymerase chain reaction(PCR) and Southern blot hybridization assay. Oligonucleotide primers used for examination of EBV strain type were derived from the EBNA-3B and EBNA-3C coding regions. As a control, four cases of reactive hyperplasia were analyzed. RESULTS: The two of four reactive hyperplasia cases were associated with type 1 and the rest of two cases with both types. Among the 18 cases with malignant lymphoma, thirteen cases(72%) had type 1, one(6%) had type 2, and four(22%) had dual infections with both types. In case of NK/T cell lymphoma(14 cases) occupying 78% of 18 biopsy samples, 86%(12 cases) were associated with type 1, 7%(1 case) with type 2, and 7%(1 case) with both types. In case of Hodgkin's disease, all of three cases had both types. B cell lymphoma taking only one case of twenty two cases was determined as type 1. CONCLUSION: These observations indicated that type 1 EBV was predominant in Korean patients with malignant lymphoma, especially NK/T cell lymphoma and showed high frequency of dual viral infections(22%) in Hodgkin's disease as well as in reactive hyperplasia.

BACKGROUND: This prospective cohort study was carried out to investigate the relation of lifestyle variables to total mortality in residents aged 60-64 of a rural community in Korea. METHODS: A total of 1,042 residents was interviewed by face-to-face survey for baseline data collection in 1996 and 955 residents were successfully followed up until April 2002, among which 91 died. RESULTS: In univariate logistic regression, consumption of cigarette per day, duration of smoking, status of smoking, frequency of drinking per month, status of drinking, average duration of TV watching per day and average duration of sleeping were statistically significant, predicting total mortality. None of the variables reflecting leisure-time physical activities were statistically significant. Adjusting for sex, age, education, current as well as past chronic diseases history, and limitation of daily living with multiple logistic regression, those smoking more than 40 years and current smokers showed reduced, but statistically significant RRs, 1.89 (95% CI 1.05-3.41) and 1.82 (95% CI 1.01-3.25), respectively. Sleeping more than 10 hours a day showed RR, 2.41 (95% CI 1.11-5.22). CONCLUSION: These results suggested that some lifestyle variables, smoking and sleeping were predictive of total mortality while drinking, TV watching and leisure-time physical activities were not.

Histopathological findings, clinical picture, various laboratory data and correlation of them to response of the patients to steroid therapy were analyzed in 9 nephrotic who had been admitted to the Seoul National University Hospital during the period of 3 years and 6 months from March of 1975 till September of 1978, and who were confirmed to have pure mesangial proliferative glomerulonephritis by renal histology. All patients were followed-up at least 1 year, up to 3 years. Age of the patients at the onset was widely distributed from 2 to 14 years, but most patients, (7 cases in 9) were after the age of 6 years. Selected findings of blood and urine examinations revealed typical patterns of the nephrotic syndrome and there was no case without edema of any degree. Histopathological study showed characteristic glomerular mesangial hypercellularity and lobular stalk widening. According to severity of the glomerular mesangial hypercellularity the patients were divided into 2 groups, one with milder changes and the other with more severe ones. There were no difference of degree of symptoms, laboratory data and response to steroid therapy between the 2 groups of the patients. But the pattern of response to steroid therapy as a whole was conspicuously different from that seen in cases with minimal change lesion. During the observation period, there were 2 cases of relapse, but case of renal failure or death was, absent possibly because the observation period was short. There was no case who developed serious side effect of steroid so as to stop administration of the drug.
