E-cadherin (ECD) is a Ca++ -dependent adhesion molecule which plays a major role in the maintenance of intercellular adhesion in epithelial tissues. The expression pattern of ECD in 77 surgically resected gastric adenocarcinomas was examined by immunohistochemistry, using a rat monoclonal antibody raised against murine E-cadherin (DECAM-1). ECD was strongly expressed uniformly at cell to cell borders in normal gastric epithelium without exception. But, various staining patterns were observed in the cancer tissues. The frequency of tumors with preserved ECD expression (Pre-type) and reduced ECD expression (Rd-type) was 44% and 56%, respectively. Using Lauren's classification, the high frequency of the Pre-type expression in adenocarcinoma of the intestinal type was significantly higher than that in adenocarcinoma of the diffuse type (p<0.05). But, no significant correlation between the ECD expression and the gross type, invasion depth, growth pattern or metastasis was observed. These results suggest that ECD might play a key role in the morphogenesis of gastric adenocarcinoma.

Myometrial pregnancy developing in an previous cesarean section scar is the rarest of all ectopic pregnancy and provavly one of the most dangerous because of the risk of rupture and hemorrhage. For a young patient wanting to maintain her fertility, an earlier diagnosis and more conservative treatment are highly desirable. We present a case of an ectopic pregnancy embedded in the myometrium of a previous cesarean section scar in which the patient preserved her fertility through more noninvasive method, transvaginal ultrasound-guided Methotrexate injection.

The 2015 Middle East respiratory syndrome (MERS) outbreak in the Republic of Korea, which started with an imported case and spread throughout the country with a total of 186 cases, revealed the vulnerabilities of the health-care system of the country. The situation was compounded by the unique health-care settings in the Republic of Korea, including crowded emergency departments and large numbers of hospital visitors seeking care at multiple hospitals. To assist with the outbreak response, the Ministry of Health and Welfare of the Republic of Korea hosted several international joint missions that provided valuable information and recommendations for MERS control and prevention of future outbreaks. This report briefly summarizes the missions’ outcomes and discusses their positive impacts.

BACKGROUND: As indicators of obesity, waist circumference (WC), body mass index (BMI), and adiponectin are well known risk factor for diabetes mellitus. The objectives of this study were to measure the independent association between these obesity indicators and diabetes and to examine the combined effect of these indicators on diabetes in a Korean population. METHODS: The WC, BMI, and serum adiponectin were measured in 6,505 healthy Koreans and were classified into tertile groups for men and women. The independent and combined associations of the obesity indicators with diabetes were measured using logistic regression analyses. Diabetes was defined as fasting serum glucose greater than 126 mg/dL or taking medication. RESULTS: Levels of adiponectin were inversely associated with BMI and WC and directly associated with age and high density lipoprotein cholesterol (HDL) cholesterol (P <0.001). After adjusting for age, WC, and other lifestyle factors, low levels of adiponectin were associated with an increased prevalence of diabetes. Further adjustment for HDL cholesterol and triglyceride attenuated this association in both men and women. The best cut-off value of adiponectin in terms of identifying the presence of diabetes was 5.5 /ml with a sensitivity and specificity of 46.7% and 63.9% for men and 9.5 /ml with a sensitivity and specificity of 68.2% and 55.2 for women. CONCLUSIONS: These results suggest that adiponectin was associated with diabetes. The association was independent of WC and was partly modified by HDL and triglyceride. There were no effect modifications of adiponectin with WC on diabetes.

Sebaceous epithelioma is a relatively rare tumor, mostly occuring in the face or scalp. The histogenesis and clinical and pathological features of sebaceous epithelioma have not been clearly defined, and a few other diagnostic terms have been used so far instead of sebaceous epithelioma. Two cases of sebacous epitheliomas were presented. No recurrence or metastasis was observed in our cases, so sebaceous epithelioma is considered to be a benign tumor. A brief review of the literature, concerned about the biological behavior, histogenesis and pathological findings of the sebaceous epithelioma, was made.

Confluent and reticulated papillomatosis (Gougerot and Carteaud) is a rare but clinically distinct dermatosis of which the etiology is unknown. We report 2 cases. One case is a 16-year-old boy who had a hyperpigmented reticulated eruption on the trunk and both arms and the other case is a 33-year-old man who had a similar eruption on the chest and back. The former, with previous treatment with oral and topical antifungal agent in another clinic didn't show any improvement and the latter case, with initial treatment of itraconazole did not improve his skin lesion. The rashes of two patients virtually disappeared with administration of minocycline. These observations indicate that the role of microorganisms sensitive to minocycline or anti- proliferative effect of minocycline could be presumed.
