PURPOSE: Many studies have shown that regular exercise produces positive effects on health. The purpose of this study was to examine the differences of health-related quality of life by stage of exercise and the interaction effect of age, sex and stage of exercise. METHOD: A total of 1266 participants were interviewed with structured questionnaire. Stage of exercise was assessed with a single item and respondents were classified with respect to exercise intention and behavior. Health-related quality of life was measured with SF-36 Health Survey Questionnaire. RESULT: Health-related QOL were found to be different by stage of exercise. The subjects who were reached maintenance stage showed significantly higher scores on physical functioning, bodily pain, general health perception, mental health, role limitation due to emotional problems, social functioning, and vitality than those in preparation, contemplation, and precontemplation stage. In addition a significant interaction effect between stage of exercise and age was found on physical functioning, bodily pain, general health perception, mental health, and vitality. CONCLUSION: Perceived health-related QOL varies with stage of exercise. This finding suggests that health is related to both intention and behavior of exercise. Therefore it is important to consider cognitive-motivational and behavioral stage of change for developing exercise programs.

Deep palmoplantar warts (Myrmecia) are frequently tender papules or plaques caused by HPV-1. Myrmecia are usually misdiagnosed as paronychia or digital mucous cysts. They occur not only on the palms and soles but also on the lateral aspects and tips of the fingers and toes. We report a rare case of deep palmoplantar wart occurring on proximal nail fold, unusual site of right 5th finger in an 11-year-old girl.

From Jan. of 1990 to Dec. of 1992, we have experienced three cases of multiple primary malignant neoplasms originated from different histogenesis, in the Department of Orthopedic Surgery of Korea Cancer Center Hospital. Liposarcomas, malignant fibrous histiocytoma were combined with renal cell carcinoma, mucinous cystadenocarcinoma of ovary or prostatic cancer. With Moertel's classification, synchronous tumors were found in 2 cases and metachronous in 1 case. Synchronous tumors were 2 liposarcomas-renal cell carcinoma or mucinous cystadenocarcinoma of ovary. Metachronous tumors were malignant fibrous histiocytoma-prostate cancer. We couldn t find any family history among them. The causes of these multiple malignancies were considered as the individual predilrection to tumors.

BACKGROUND: Germline mutations in the breast cancer-associated genes BRCA1 and BRCA2 confer susceptibility and a lifetime risk of breast. Several morphological and clinical features have been attributed to hereditary tumors. However, in sporadic breast cancer, the interrelationship between the loss of heterozygosity (LOH) of these loci and clinical features remains to be fully elucidated. METHODS: Microdissected paraffin-embedded tissue blocks of 48 cases of surgically resected breast carcinoma were investigated to identify the LOH of BRCA1 and BRCA2 using microsatellite markers. RESULTS: Of 48 cases, 22 (45.9%) exhibited LOH at BRCA1 locus while in 29 out of 48 (60.4%) cases LOH was observed for the BRCA2 region. There was no significant correlation between LOH at BRCA1/2 and the patient's age, tumor size, histologic grade or lymph node metastasis. When comparing the frequency of LOH with the expression of several prognostic factors, such as p53, c-erb B2 protein, estrogen and progesterone receptor using immunohistochemical stain, there was only correlation with LOH at BRCA2 and the progesterone receptor. CONCLUSIONS: Our results suggest that allelic deletion play a role to the development of sporadic breast cancers.

BACKGROUND: Left ventricular hypertrophy(LVH) is a powerful indepedent risk factor of ventricular tachycardia and sudden death. Even though it is not clear the mechanism of sudden death in patients with LVH, inhomogenous ventricular repolarization is highly suggested. QT dispersion which reflecting regional inhomogeneity of repolarization is defined as interlead variation in QT intervals of 12 leads ECG. The purpose of this study was to assess whether QT dispersion is associated with LVH in hypertensive patients. METHODS: We assessed 23 untreated hypertensives with echocardiographic LVH and normal left ventricular systolic function. The criteria of 5th Joint National Committee stage I-III was used to define hypertension. Thirty four normotensives was assessed as controls. On a standard 12 lead ECG, the intervals between onset of QRS to end of T wave were measured(QT intervals) and corrected by heart rate(QTc). QT dispersion was calculated by the difference of maximal and minimal QTc. Left ventricular mass(LVM) was calculated from Devereux's formula using the parameters measured by the recommendation of American Society of Echocardiography. LVH was defined by LVM indices over 130 g/m2. RESULTS: LVM indices of hypertensive group were significantly greater than those of controls (162.2+/-39.3 g/m2 vs 84.2+/-16.1 g/m2, p<0.001). Maximal QT and QTc of hypertensive group were significantly prolonged than those of controls(maximal QT=401+/-31 ms vs 380+/-35 ms, p<0.05 ; maximal QTc=432+/-19 ms vs 414+/-17 ms, p<0.001). QT dispersions were significantly greater in hypertensive group than in controls(60.2+/-15.7 ms vs 33.2+/-11.7 ms, p<0.001). In hypertensive group, there was significant association between LVM index and QT dispersion(r=0.492, p=0.017). CONCLUSIONS: Hypertensives with LVH have a prolonged QT and QTc and increased QT dispersion in comparision with controls. QT dispersion in these patients correlates with degree of LVH.

Multiple lymphomatous polyposis (MLP) is an uncommon type of primary non-Hodgkin's gastrointestinal B cell-lymphoma characterized by the presence of multiple lymphomatous polyps along the gastrointestinal tract. Unlike MALT-lymphoma, MLP has a strong tendency for histologically monomorphic character, extra-digestive localization, rare lymphoepithelial lesion and poor prognosis. The malignant cells of MLP share morphological, immunohistologic and cytogenetic similarities with cells of node-based mantle cell lymphoma. We report a case of mantle cell lymphoma presenting with MLP involving various segments of the gastrointestinal tract, skeletal muscles of the right thigh and bone marrow observed in a 71-year-old woman who complained of lower abdominal pain and a palpable right thigh mass.

PURPOSE: For prevention of renal scar, early diagnosis and treatement of acute pyelonephritis are important in children with febrile urinary tract infection. But it has been difficult to differentiate acute pyelonephritis from lower urinary tract infection. We have performed this study to evaluate the diagnostic value of 99mTc-DMSA renal scan and to clarify the relationship among acute pyelonephritis, vesico-ureteral reflux and renal scar. METHODS: We have studied 100 patients with febrile urinary tract infection, from September, 1993 to June, 1995 at the Pediatric department of Ewha Womans University, Mok-dong hospital. Acute phase reactants, causative organism, renal ultrasound, 99mTc- DMSA renal scan on the acute stage, voiding cystouretherogram after 1-2 weeks of treatement, and follow-up 99mTc-DMSA renal scan were evaluated. RESULTS: Ther results are as follows; 1) 57 patients (57%) had defect on 99mTc-DMSA renal scan and diagnosed as acute pyelonephritis. 2) Acute phase reactants, renal ultrasound had low accuracy. 3) VUR was found in 31 (56.1%) of 57 patients with defect which was significantly higher than the 4 (9.3%) of 43 patients without defect on 99mTc-DMSA renal scan. 4) On the follow up 99mTc-DMSA renal scan, 34.8% of defects recorvered, and 65.2% of defects developed renal scar. CONCLUSIONS: 99mTc-DMSA renal scan is a valuable method for early diagnosis of acute pyelonephritis in children with febrile urinary tract infection. It would contribute to evaluate the relationship between acute pyelonephritis, vesico-ureteral reflux and renal scar.
