Stomach cancer is one of the major causes of cancer deaths in Korea. It has been well known, like other solid tumors, that cancer stage at diagnosis is the most important prognostic factor in gastric cancer. Previous studies from Japan have revealed that screen-detected gastric cancers showed an earlier stage distribution and had a lower mortality rate than symptom-diagnosed cases. Considering the high provalence and substantial mortality from gastric cancer in Korea, it seems necessary to establish a well organized nationwide screening program. In this regard, consensus meeting was held in January, 2002 in conjunction with The Koean Gastric Cancer Association and National Cancer Center in Korea. In this meeting, specialists from gastroenterology, surgery and radiology drew a conclusion as follows : biannual screening for people aged 40 years and over either by endoscopy or upper gastrointestinal series. During the screening endoscopy, biopsy can be performed if necessary, and specimens should be examined by pathologist. Screening test should be performed in authorized hospital or mobile unit by qualified doctors.

Solitary morphea profunda is a rare form of scleroderma, characterized clinically by a solitary sclerotic plaque, and histologically by marked dermal and subcutaneous fibrosis with an inflammatory infiltrate. We describe another case of this entity presented with an ulcerative, indurated plaque on the left iliac crest, which histologically revealed a focal incidental acantholysis in the overlying epidermis and a marked eosinophilic infiltration through the dermis to the sub-cutaneous tissue.

BACKGROUND: The immortalized human keratinocyte line, HaCaT cells have been widely used as substitutes for normal epidermal keratinocytes. Recently, reconstruction of a skin equivalent using HaCaT cells showed a multilayered epithelium,but somewhat different tissue architecture as compared with normal epidermis. OBJECTIVE: In this study, using HaCaT cells we tried to reconstruct an epidermis resembling more closely to normal epidermis than the previous results. MATERIALS AND METHODS: HaCaT cells were cultured in air-liquid interface on a recently developed dermal substrated in our laboratory, de-epidermized dermis (DED) raised on fibroblast-populated collagen matrix and the result was compared with those on DED or fibroblast-populated collagen matrix alone. RESULTS: HaCaT cells on the new dermal substrate formed a multilayered epithelium with rete ridges, showing rather orderly cellular organization compared with those on fibroblast-populated collagen matrix. However, horny and granular layers were not observed contrary to normal epidermis. Immunohistochemical studies revealed that differentiation markers such as keratin 1, keratin 6 and involucrin showed the similar pattern to those in HaCaT cells cultured on fibroblast-populated collagen matrix. Markers of terminal differentiation, loricrin and filaggrin were not expressed contrary to normal epidermis. CONCLUSION: These results suggest that organotypic culture HaCaT cells on the dermal substrate combines DED with fivroblast-populated collagen matrix results in incomplete differentiation of HaCaT cells contrary to normal keratinocytes.

We described a case of diffuse biphasic cutaneous amyloidosis, a unique form of localized cutaneous amyloidosis. A 41-year-old man has gradually developed a lichenoid papular and a grouped spotted pigmented macular eruption on the trunk and upper extremities over the past 15 years. Histopathologic examination revealed that amyloid deposits were present in the papillary dermis. It was confirmed by Congo red staining, immunohistochemistry and electron microscopy. There was no evidence of systemic amyloidosis.

BACKGROUND: We compared factors associated with self-reported depression and, in particular, diagnosis and treatment of depressive symptoms in Korean adults. METHODS: The sample included 13,306 adults aged 19 years or older from the 2010 and 2011 Korea National Health and Nutrition Examination Survey (KNHANES V). Data were applied to the chi2 test and multivariate logistic regression analysis. RESULTS: The following characteristics of individuals are significantly associated with self-reported depression: female (vs. male, OR [odds ratio]=3.35), ages 50-59 years (vs. 60+, OR=1.45), economic status (low vs. high, OR=1.35; middle-low vs. high OR=1.29), unemployed (vs. employed, OR=1.23), education (elementary vs. college, OR=1.18; middle school vs. college, OR=1.27; vs. high school vs. college, OR=1.18), current smoking (vs. no, OR=1.19), high-risk alcohol consumption (vs. no, OR=1.18), perceived health (good vs. very good/excellent, OR=1.156; poor/fair vs. very good/excellent, OR=2.65), chronic disease (vs. no, OR=1.26), activity limitation due to health problems (vs. no, OR=1.74), and being in a sickbed during the past month (vs. not in a sickbed, OR=1.69). Living in a metropolitan area (vs. rural, OR=1.40) is significantly associated with greater odds of being diagnosed with depression. The odds of being treated for depression are lower for female (vs. male, OR=0.53). Greater odds of being treated for depression was seen for those with chronic conditions (vs. no, OR=1.73) and activity limitation due to health problems (vs. no, OR=2.05), as well as, those in a sickbed (vs. not, OR=1.88). CONCLUSIONS: Applying our findings, policy makers should address the lower rates of depression diagnosed in non-metropolitan areas to reduce regional variations, and also promote treatment in females.
