Pigmented squamous cell carcinoma is a very rare malignant, pigmented, epidermal tumor. The rarity of pigmented squamous cell carcinomas may reflect in part their misdiagnosis as other pigmented neoplasms, particularly malignant melanoma. To our knowledge, only five cases have been reported in literature. We recently experienced a case of pigmented squamous cell carcinoma arising from pigmented actinic keratosis in a 77 years old female. Physical examination showed a 0.8 0.6 cm, smooth, dark brown pigmented patch with irregular but sharply defined borders located on the upper left chest. The biopsy specimen showed histologic findings of pigmented actinic keratosis with abundant melanin pigments, which became pigmented squamous cell carcinoma. Most of pigments in the squamous cell carcinoma were contained within the melanocytes along with the neoplastic squamous cells.

This study investigated the trends of gastric cancer in Korea by adding the latest updated gastric cancer data from 2019. Gastric cancer incidence between 1999 and 2019 was reviewed using data from the Korea Central Cancer Registry. The study period was divided into 3 periods: period I (1999–2005), period II (2006–2012), and period III (2013–2019). The incidence, mortality, tumor location, histology, stage, and treatment were analyzed.Between 1999 and 2019, 577,502 patients were newly diagnosed with gastric cancer in Korea, accounting for 33.2% of patients aged ≥70 years. The age-standardized incidence rate (per 100,000) significantly decreased from 2011 (43.0) to 2019 (29.6), with an annual percent change of −4.50. Additionally, the age-standardized mortality rate (per 100,000) markedly decreased from 1999 (23.9) to 2019 (6.7). The proportions of patients with cardia and fundus cancers remained consistent. The proportion of localized stage cases increased, while those of regional and distant stages decreased. The rate of surgical treatment increased in localized and regional stages from 2006 to 2019. The overall 5-year relative survival (5YRS) rate of gastric cancer (per 100,000) increased from 55.7% in period I to 77.0% in period III. From 2013 to 2019, the 5YRS rates of patients (per 100,000) who underwent surgical treatment were 100.6% and 70.5% in the localized and regional stages, respectively. The results of this study demonstrated several changes in the epidemiology of gastric cancer in Korea. This study provides information to help understand the current trends in gastric cancer in Korea.

OBJECTIVE: To compare maternal characteristics and pregnancy outcomes in a group of women with gestational diabetes mellitus(GDM) diagnosed in our hospital with those of women without this disorder. MATERIALS AND METHOD: This is a retrospective study of 402 gestational diabetic women with singleton cephalic presenting pregnancies delivered at Ilsin Christian Hospital during the period January 1, 1997, through December 31, 1999. National Diabetes Data Group thresholds were used to diagnose gestational diabetes. Women in this group were compared with a nondiabetic control group(n=430) randomly selected and effects of confounding variables were analyzed using stratified analysis. RESULTS: Prevalence of GDM was 2.36%. Women with gestational diabetes were significantly older, heavier, of greater parity and more often had the following risk factors for GDM. Hypertension, cesarean delivery, macrosomia, and large for gestational age(LGA) rate were significantly increased. The adequate treatment group diagnosed before 32wks and received glucose control was compared with a inadequate treatment group. And there was no significant difference in maternal characteristics and pregnancy outcomes between the two groups. Within the adequate treatment group, three groups were subdivided by birth weight as SGA(small for gestational age), AGA(appropriate for gestational age) and LGA. The group with LGA had no difference in age, parity, pregnancy-induced hypertension, 2hr mean postprandial glucose level except body mass index and insulin treatment rate. After adjusting these two factors with stratified analysis, there was no general association between birth weight and glucose level(p=0.342). CONCLUSIONS: Maternal characteristics of gestational diabetes were significantly different compared with those of nondiabetic women. Pregnancy outcomes of gestational diabetic women were not improved by our conventional management and more intensified but acceptable and compliable treatment should be tried.

OBJECTIVES: We review the sleep problems of the alcohol dependence patients. Especially we are interested in the prevalence, the severity of symptoms, anxiety, depression, and sleep quality of restless legs syndrome (RLS) in the alcohol dependence patients. METHODS: We recruit 86 alcohol dependence patients who were admitted from October 6th, 2008 to October 17th, 2008. We interviewed each patient and evaluated sleep questionnaires such as the Sleep Disorder Questionnaire (SDQ), the Pittsburgh Sleep Quality Index (PSQI) and the International Restless Legs Syndrome Study Group (IRLSSG) rating scale. The presence of RLS and its severity were assessed using the IRLSSG diagnostic criteria and the IRLSSG severity scale, respectively. Depression and anxiety were evaluated by the Beck Depression Inventory (BDI) and the Beck anxiety inventory (BAI). RESULTS: Of all 86 patients, 59 patients have insomnia, 33 patients have RLS, 30 patients have Periodic limb movement disorder (PLMD), 29 patients have nightmare. RLS patients have more high score in the BAI (21.70+/-10.36 vs 14.67+/-11.98), and their sleep quality was poor in the PSQI (11.09+/-4.08 vs 7.92+/-3.91) than non-RLS patients. CONCLUSION: This study shows that alcohol dependence patients show many sleep problems such as insomnia and RLS. So we should notice that the sleep problems of alcohol dependence patients are important in clinical approach and treatment.

Diatomology has provided important evidences for diagnosis of drowning in forensic practice. However, conflicting opinions about the reliability of diatom test still exist. As a part of efforts to end this controversy, it is very important to secure the diatom profile in the water sample of drowning site. Our results obtained in this study show the characteristics of temporal and spatial distribution of diatom collected from the main drowning sites of Han river in Korea. During spring, 111 taxa (98 species and 13 varieties) were identified from 31 genera, and 87 taxa (77 species and 10 varieties) were identified from 22 genera during summer. At the level of genus Achnanthes, Cyclotella, Cymbella, Fragilaria, Navicula, Nitzschia, and Stephanodiscus represented the highest numbers, and were the most widely occurred during two seasons. The centric diatoms, Stephanodiscus hantzschii f. tenuis and Cyclotella atomus were typical of spring and summer, respectively, and identified as dominant indicator species. The commonly occurred species, including dominant species in the seasonal cluster analysis influenced the formation of site - specific groups. As a result, our results will be able to be used not only as the comparison data of diatom found in the drowning victim's tissue but also a reference data to rule out the possibility of contamination.
