Hydranencehaly is an abnormality consisting of complete or almost absence of the cerebral hemispheres, which are replaced by a large fluid-filled cavity. The midbrain and brain stem are relatively intact, and rudiments of frontal, temporal and occipital cortex may be present. We diagnosed it through the evaluation of clinical features, prenatal US (intrauterine pregnancy, 37 wks) and brain CT. Authors have experienced a case of hydranencephaly combined with twin pregnancy and reported with a brief literature review.

BACKGROUND: Adenocarcinoma of the esophagus has been reported to be increasing in incidence in a number of regions throughout the world, while the incidence of squamous cell carcinoma (SCCA) of the esophagus is mostly stable or decreasing. To evaluate the increasing tendency of adenocarcinoma of the esophagus. METHODS: we studied retrospectively the records of patients with histologically proven esophageal cancer between 1970 and 1999 at the Yonsei Medical Center. RESULTS: Total cases of esophageal cancer were 969 patients of which the cases of adenocarcinoma and SCCA were 27 patients and 918 patients, respectively. The ratio of esophageal adenocarcinoma to SCCA was 0.0375 in the 1970s, 0.0241 in the 1980s and 0.0292 in the 1990s. There was no statistical difference (p=0.811) in the ratios of adenocarcinoma of the esophagus between the three consecutive 10-year groups. CONCLUSION: In conclusion, unlike the US and other western countries, it seems that the ratio of esophageal adenocarcinoma compared to SCCA has not increased among patients with esophageal carcinoma at the Yonsei Medical Center.

PURPOSE: This study was to investigate depression prevalence and related factors of depression in Jeju Province. METHODS: The study sample selected using randomized cluster sampling method, and the unit of cluster was 25 households. Data were collected from 1275 adults in 723 households through home visit interview. The response rate was 89.4%. The instrument used for measuring depression was CES-D, the cut-off score was 21. Data were analyzed using Chi-square test and logistic regression. RESULTS: The prevalence of depression in Jeju was 18.1%. The significant differences were found with depression prevalence rate by the group of gender, age, inhabited area, marital status, educational status, monthly household income, life satisfaction, socioeconomic status, perceived health status, morbidity during last 2 weeks, perceived stress, perceived fatigue, participation in social activities, and family life satisfaction. The most predictive factors among those variables were perceived fatigue with 17.93 of odds ratio, family life satisfaction with 9.86 odds ratio, and perceived stress with 9.66 of odds ratio. CONCLUSION: The prevention and management of depression program development was suggested and mental health promotion program for the prevention of depression was suggested.

Purpose: Antivascular endothelial growth factor (anti-VEGF) agents are routinely intravitreously injected to treat neovascular age-related macular degeneration (AMD). Postoperative endophthalmitis, a side effect after intravitreal anti-VEGF injection, has been reported to have a low incidence but may threaten vision. In this study, we aimed to analyze the incidence of acute endophthalmitis after intravitreal anti-VEGF injection and associated risk factors in patients with neovascular AMD in South Korea. Methods: Using the health claims data recorded in the Korean National Health Insurance System database, we identified newly developed neovascular AMD cases from 2010 through 2019. Acute endophthalmitis was defined as a case of invasive treatment for accompanying symptoms. All statistical analyses were performed with a significance level p < 0.05. To find risk factors, we used univariate and multivariable Poisson regression. Results: The overall incidence of acute endophthalmitis was 0.019% (p = 0.21) during the 10-year period: 0.025% for aflibercept injection and 0.014% for ranibizumab injection. The incidence was higher in metropolitan city residents than in Seoul (incidence rate ratio [IRR], 1.96; 95% confidence interval [CI], 1.02–3.79; p = 0.04) and was higher for aflibercept injections than for ranibizumab injections (IRR, 1.82; 95% CI, 1.17–2.82; p = 0.01). However, in multivariate analysis, only aflibercept injections showed a significant effect on the incidence of acute endophthalmitis (IRR, 1.80; 95% CI, 1.16–2.79; p = 0.01). Conclusions The incidence of acute endophthalmitis after intravitreal anti-VEGF injections was generally low, and aflibercept was revealed as a significant risk factor.

BACKGROUND: Lipoprotein lipase(LPL) plays a pivotal role in triglyceride-rich lipoprotein metabolism. It removes TG-rich lipoprotein from circulation by hydrolysing TG and produces active form of HDL. It also affects the development and maintenance of obesity by regulating the fatty acid metabolism of the adipose tissue. Many studies about the association of the genetic variation of LPL and dyslipidemia have been performed, but the results were not consistent. We tried to characterize the phenotypes of the LPL genetic variation in Korean. METHODS: Healthy Korean adults (n=110) were genotyped for Hind III/Pvu II RFLP and Ser447Ter mutation of the LPL gene by PCR-digestion method. We investigated the association of the genetic variations with the lipids, the lipoprotein concentrations and the body mass index(BMI). RESULTS: The allele frequencies of Hind III RFLP, Pvu II RFLP and Ser447Ter mutation were H1:H2=33%:67%, P1:P2=40%:60% and Ser447: Ter447=90%:10%. Ser447Ter mutation carriers had higher HDL cholesterol level than non-carriers (59+/-10mg/dl versus 53+/-11mg/dl, p=0.049) and the Pvu II RFLP is associated with increased body mass index. (P1P1:P1P2:P2P2 = 22.1+/-2.0 kg/m2: 23.5+/-2.7 kg/m2: 24.5+/-2.6 kg/m2, p=0.003) CONCLUSION: The genetic variations of the LPL gene in healthy Korean adult resulted in increased HDL cholesterol and increased BMI. These results were different from previous studies. This difference may reflect the racial difference from the diet and the linkage disequilibrium

BACKGROUND: There have been no previous studies on the effect of anesthetic agents on rhinovirus (RV) infection, which is the most common pathogen of the common cold in human airway epithelial cells. We investigated the effects of propofol and etomidate on the airway epithelial cells infected with RV. METHODS: RV-infected A549 cells were treated with propofol and etomidate for 24 hours. On the third day of infection, cells and supernatant were collected to measure the intercellular adhesion molecule-1 (ICAM-1) expression, viral titer and the amount of cytokine. The extents of the viral replication were expressed as viral titers by 50% tissue culture infection dose (TCID50). RESULTS: The ICAM-1 expression of the groups treated with propofol 1, 10, 100micrometer vs etomidate 1, 5, 25micrometer were 15.6 +/- 4.2, 16.4 +/- 3.7, 14.1 +/- 4.7% vs 16.8 +/- 5.7, 16.4 +/- 5.3, 17.2 +/- 4.5%, but there were not significantly different among subgroups. Productions of cytokines were increased after RV-infection, but there were not significantly different among the propofol and etomidate treated subgroups. The viral titers of the groups treated with propofol and etomidate were not significantly different among subgroups either. CONCLUSIONS: Propofol and etomidate had no effect on the replication of RV and the cytokine release after RV infection in human airway epithelial cells.

OBJECTIVE: Little is known about the characteristic differences in alexithymic construct in various psychiatric disorders because of a paucity of direct comparisons between psychiatric disorders. Therefore, this study explored disorder-related differences in alexithymic characteristics among Korean patients diagnosed with four major psychiatric disorders (n=388). METHODS: Alexithymic tendencies, as measured by the Korean version of the 20-item Toronto Alexithymia Scale (TAS-20K), of patients classified into four groups according to major psychiatric diagnosis were compared. The groups consisted of patients with depressive disorders (DP; n=125), somatoform disorders (SM; n=78), anxiety disorders (AX; n=117), and psychotic disorders (PS; n=68). RESULTS: We found that substantial portions of patients in all groups were classified as having alexithymia and no statistical intergroup differences emerged (42.4%, 35.9%, 35.3%, and 33.3% for DP, SM, PS, and AX). However, patients with DP obtained higher scores in factor 2 (difficulties describing feelings) than those with SM or AX, after adjusting for demographic variables. CONCLUSION: These findings suggest that alexithymia might be associated with a higher vulnerability to depressive disorders and factor 2 of TAS-20K could be a discriminating feature of depressive disorders.

Inverted papillomas are uncommon benign epithelial tumors which typically occur on the lateral wall of the nose or paranasal sinuses. Inverted papilloma of the nasal septum account for between 5.5% and 16.7% of inverted papilloma. Histopathologically, these tumors show inversion of the neoplastic epithelium into the underlying stroma, rather than proliferating outwards. The tumors also demonstrate local aggressiveness, a high recurrence rate and the possibility of malignant transformation. Malignant transformation rate varies from 2% to 53%. But there is no clinical prognostic indicator to show the malignant potency of tumors. Therefore, early diagnosis and careful follow-up is very important. Some cases of this condition have been reported in otolaryngologic literature, but there are no reports of it in dermatologic literature. Herein we report a case of squamous cell carcinoma arising from an inverted papilloma in the nasal septum of a 78-year-old man.

OBJECTIVES: To evaluate the Community-Based Participatory Research (CBPR) professional periodontal care program model for patients with hypertension and diabetes. METHODS: This descriptive case study included 151 participants of the professional periodontal care program. The CBPR-based professional periodontal care program consists of 5-steps: ‘Issue identification and prioritization’ (Step 1), ‘Strategy development’ (Step 2), ‘Entry into community’ (Step 3), ‘Implementation’ (Step 4), and ‘Transition’ (Step 5). Quantitative data were analyzed using frequency analysis, and descriptive data with PASW 23.0 (SPSS Inc., Chicago, IL, USA). The results of the Focus group interview (FGI) were classified as ‘general opinions regarding the program planning and operation receptiveness’, ‘sustainability’, ‘potential spread of the program’, and ‘improvement of program’. The interviews were qualitative research involving seven people. RESULTS: 1. Participants increased their interest in health and oral health by managing their hypertension, diabetes, and periodontal disease using community resources. Through this, healthy practices and improved awareness helped to prevent complications and manage periodontal diseases. 2. Community organizations actively cooperated, resulting in positive changes in oral health practices (increased registration of patients in education centers for hypertension and diabetes, and increased number of patients visiting the local dental clinic). In the future, it was positive to participate in the program continuously. CONCLUSIONS: The most important step is ‘Entry into community’, which has led to active participation and cooperation of community organizations and participants. Therefore, community organizations and strategy development should be discussed, and the role of community leaders should be emphasized to build cooperative relationships. In addition, participation in and collaboration with health-based projects should be achieved through a search of various community organizations.
