BACKGROUND: The purpose of this study was to analyze the relationships between cardiorespiratory fitness and body mass index (BMI), metabolic syndrome risk factors, homeostasis model assessment-insulin resistance (HOMA-IR), and high sensitivity C-reactive protein (hsCRP) in male high school students in Korea. Furthermore, the effects of the cardiorespiratory fitness levels on these four factors were examined. METHODS: The level of cardiorespiratory fitness, BMI, percent body fat, waist circumference (WC), systolic blood pressure, glucose, triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), HOMA-IR, and hsCRP of 227 male high school students were measured. Analyses of multiple correlation and simple regression were applied. RESULTS: The results showed that the level of cardiorespiratory fitness correlated negatively with BMI, percent body fat, WC, TG, and HDL-C, in addition to HOMA-IR and hsCRP, and strongly influenced BMI, percent body fat, WC, TG, HDL-C, HOMA-IR, and hsCRP. Comparative analysis of our subjects showed that higher cardiorespiratory fitness levels had positive effects on BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. CONCLUSIONS: This study found that there are close correlations between cardiorespiratory fitness and BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. It also showed that, compared to lower levels of cardiorespiratory fitness, higher levels had beneficial effects on BMI, metabolic syndrome risk factors, diabetes, and cardiovascular disease risk factors.

Choriocarcinoma of the gastrointestinal tract is rare. Among them, that of the stomach is the most common. Six cases of choriocarcinoma of the colon were found in the review of the literature. All of these previously reported cases had multiple metastatic foci in the liver, lung, lymph nodes and the prognosis seemed to be very poor. Therefore we think that choriocarcinoma of the colon should be distinguished from conventional adenocarcinoma. A 66-year old female patient, described in this case, was operated on under the impression she was suffering from acute appendicitis. The resected ascending colon revealed extensive hemorrhagic necrosis and perforation with fibrous adhesion in the cecum. On the cut section, the mural tumorous thickening was not definite. Histologically, the tumor showed a focus of typical adenocarcinoma arising from glandular epithelial cells, which were transformed into highly anaplastic tumor cells. There were frequent vascular invasions of tumor cells, similar to syncytiotrophoblasts. In the immunohistochemical stains, both glandular and highly anaplastic tumor cells reacted with cytokeratin. The glandular cells were also reactive for carcinoembryonic antigen (CEA) and anaplastic tumor cells for human chorionic gonadotrophin (hCG). This is the first report of choriocarcinoma of the colon in Korea. We describe this case with a review of the literature.

OBJECTIVES: This study was conducted in order to determine how the association between socioeconomic position(SEP) and health status changes with age among Seoul residents aged 25 and over. METHODS: We utilized the 2001 and 2005 Seoul Citizens Health Indicators Surveys. We used self-rated 'poor' health status as an outcome variable, and family income as an indicator of SEP. In order to characterize the differential effects of socioeconomic position on health by age, we conducted separate multivariate analyses by 10-year age groups, controlling for sociodemographic covariates. In order to assess the relative health inequality across socioeconomic groups, we estimated the Relative Index of Inequality (RII). RESULTS: The risk of 'poor health' is significantly high in low family income groups, and this increased risk is seen at all ages. However, the magnitude of relative socioeconomic inequality in health, as measured by the odds ratio and RII, is not identical across age groups. The difference in health across income groups is small in early adulthood (ages 25-34), but increases with age until relatively late in life (ages 35-64). It then decreases among the elderly population (ages more than 65). When the RII reported in 2005 is compared to that reported in 2001, RII can be seen to have increased across all ages, with the exception of individuals aged 25-34. CONCLUSIONS: The magnitude of health inequality is the greatest during mid- to late adulthood (ages 45-64). In addition, health inequalities have worsened between 2001 and 2005 across all age groups after economic crisis.

BACKGROUND: Breast cancer is the most frequent malignant neoplasm among women in the Orient. This cancer is also increasing in Korea due to westernization of the living pattern, increased recognition among the general population, and improved methods for early detection. In the surgical treatment of breast cancer, cosmetic conservation of the breast has drawn the patients' attention so that conservative surgery is increasing nowadays. The purpose of this study is to describe the current status of breast cancer management at our institution and to identify the survival and the recurrence rates according to the stage and the surgical method used. METHODS: We reviewed the medical records of 150 patients diagnosed as having breast cancer on pathologic examination at the Department of General Surgery, EulJi College of Medicine, from January 1991 to December 1996 and evaluated the clinical findings, the diagnostic method, operation, and the prognosis. RESULTS: The mean age of the patients was 49.1 years, and 34.0% of the patients was in the fifth decade. A palpable mass in the breast was the most frequent clinical symptom and sign (80.7%). The interval between symptom onset and diagnosis was about 6 months in 76.0% of patients. The size of the mass was 2~5 cm in 51.3% of the patients. A modified radical mastectomy was the most frequently employed surgical method (74.0%), but conservative surgery has increased lately. Seventy-ight patients (52.0%) were in stage II. The five-ear survival rates for stages I, II, III were 100%, 82.9%, and 55.0% (p=0.00006). The five-ear survival rates for 0, 1~3, 4~9, and more than 10 axillary-ode metastases were 85.9%, 55.3%, 53.6%, and 21.1%, respectively (p=0.0007). The five-ear survival rates for breast-conserving surgery and a modified radical mastectomy, for both stage of I and II, were 90.9% and 89.3% (p=0.8114), respectively, and the recurrence rates were 17.9% and 23.8% (p=0.88). CONCLUSIONS: The authors may conclude that breast-onserving surgery may offer an effective alternative to a modified radical mastectomy for patients with stage I & II breast cancer.

We report two human cases of tick bite. A 63-year-old male had a pruritic pea-sized brownish nodule on the left popliteal area. Another 41-year-old male had an asymptomatic bean-sized black nodule in the pubic area. The ticks were identified as Ixodes nipponensis, which are the 18th and the 19th cases in Korea.

We report a case of malignant tumor of the stomach showing both carcinoma and sarcoma components in a 47 year-old woman. The resected stomach revealed two tumors which were in different location. The one mass was a 2 x I cm, poorly demarcated tumor at the body, along the lesser curvature and the other was a 6 x 7 cm, well demarcated polypoid tumor with a central depression at cardia of the posterior stomach wall. The tumor at the body was a poorly differentiated adenocarcinoma which showed strong reactivity for CEA. The tumor at the cardia was composed of epithelioid or spindle shaped cells with abundant eosinophilic cytoplasm and revealed 5-6 mitoses per ten high power field. The tumor at the cardia was diagnosed as epithelioid leiomyosarcoma and showed reactivity for vimentin but none for actin, desmin,keratin, and CEA. This is different from the usual carcinosarcoma.

Malignant glomus tumor is a rare neoplasm arising from the glomus body, comprising categories of locally infiltrative glomus tumor, sarcoma arising in benign glomus tumor and de novo glomangiosarcoma. We report one case of locally infiltrative glomus tumor arising in nail bed of the right thumb of a 50 year-old woman. The tumor showed the architectural features of glomus tumor but cytologically bizarre, pleomorphic features without mitosis and infiltrative growth pattern to adjacent connective tissue and nerve. Immunohistochemical results were consistent with glomus tumor. This category of malignant glomus tumor must be distinguished from other round cell tumors because of its good prognosis.
