Gastritis is a major disease that has the potential to grow as gastric cancer. Gastric cancer is a very common cancer, and it is related to a very high mortality rate in Korea. This disease is known to have various reasons, including infection with Helicobacter pylori, dietary habits, tobacco, and alcohol. The incidence rate of gastritis has reported to differ between age, population, and gender. However, unlike other factors, there has been no analysis based on gender. So, we examined the high risk factors of gastritis in each gender in the Korean population by focusing on sex. We performed an analysis of 120 clinical characteristics and genome-wide association studies (GWAS) using 349,184 single-nucleotide polymorphisms from the results of Anseong and Ansan cohort study in the Korea Association Resource (KARE) project. As the result, we could not prove a strong relation with these factors and gastritis or gastric ulcer in the GWAS. However, we confirmed several already-known risk factors and also found some differences of clinical characteristics in each gender using logistic regression. As a result of the logistic regression, a relation with hyperlipidemia, coronary artery disease, myocardial infarction, hyperlipidemia therapy, hypotensive or antihypotensive drug, diastolic blood pressure, and gastritis was seen in males; the results of this study suggest that vascular disease has a potential association with gastritis in males.

In order to investigate psychological and behavioral characteristics of homosexuals and to present evidence that homosexuals are in danger of HIV infection in Korea, this study was done by self-administered questionnaire and then direct interview with the 28 (35%) HIV infected homosexual/bisexuals of 79 HIV infected persons reported in 1992. Homosexuals without heterosexual activity were 9 and the others were bisexuals. Sixty-five percent of respondents had a guilty conscience for their homosexual activty. Twenty (71%) were in twenties and 5 (18%) in thirties. Twelve(43%) were detected via health card checking by health office, 21% by blood donation, 18% by hospital visit, and 7% by partner notification. Motivations for homosexual activity were curiosity (36%), temptation or recommendation (14%) and compulsion (11%). Eighteen (72%) never used condom on anal sex. Nine of 26 respondents had experience for anal sex with foreigners. Fourteen (54%) of 26 respondents had history for sexually transmitted diseases. Fighty percent did not have sexual contact after HIV infection and the others usually used condom. It was confirmed that over 57% of the respondents were infected within 1 year before HIV diagnosis and over 82% within 2 years. These data suggest that HTV infection among homosexual group is rapidly spreading.

Rabies is a major zoonotic disease that causes approximately 55,000 human deaths worldwide on an annual basis. The nucleocapsid protein and glycoprotein genes of the Korean rabies virus (RABV) have been subjected to molecular and phylogenetic analyses. Although the phosphoprotein (P) has several important functions in viral infection and pathogenicity, the genetic characterizations of the P of Korean RABV isolates have not yet been established. In the present study, we conducted genetic analyses of P genes of 24 RABV isolates circulating in the Republic of Korea (hereafter, Korea) from 2008 to 2011. This study revealed that the P genes of Korean RABVs are genetically similar to those of RABV strains of lyssavirus genotype I including V739 (dogs, Korea), NNV-RAB-H (humans, India), NeiMeng925 (raccoon dogs, China), and RU9.RD (raccoon dogs, Russia). Among Korean isolates, the RABV P genes showed low variability in the variable domains among Korean isolates; they had specific consensus sequences and amino acid substitutions capable of identifying geographic characteristics and retained specific sequences thought to be important for viral function. These results provide important genetic characteristics and epidemiological information pertaining to the P gene of the Korean RABV.

Purpose: To provide the epidemiological information for developing preventive programs encourage appropriate eating and weight control behaviors. Method: 349 college students in Seoul were administered self-report question- naires to examine eating habits, trend of disordered eating, weight reduction practice and body size evaluation from September to October 2002. Data were analyzed by SAS program for frequency, t-test, ANOVA with Scheff test. Result: The mean eating score was moderate and it differed by subjects' characteristics. The mean score of EAT-26 was relatively lowered, and 3.4% of the subjects score showed disordered eating behavior. It differed significantly by subjects' general characteristics. 30.4% of total sample were currently trying to lose weight and had interested in trying to lose weight. EAT-26 was significantly different by weight reduction practices and interest. Perceived body size differed by the score of eating habit and EAT-26. Conclusion: It can be suggested weight preoccupation have a relation to eating habits, weight control practice and disordered eating. Further study is recommended educational interventions targeting at-risk subjects.

Background: Neurovascular compression (NVC) is a well-known cause of trigeminal neuralgia (TN). However, patients with idiopathic TN (ITN) do not have evidence of NVC on magnetic resonance imaging (MRI), and other patients may remain asymptomatic despite evidence of NVC on MRI. This suggests that there may be additional risk factors for TN development other than NVC. Although epidemiological factors, such as age and sex differences, are useful for understanding the pathophysiology of TN, detailed statistics for each TN subtype are currently unavailable. Therefore, this study aimed to classify patients with TN into the following groups based on data extracted from past medical records: classical TN (CTN), secondary TN, and ITN. Methods: The characteristics of the groups and their differences were explored. Results: CTN was more common in women than in men, as previously reported, whereas ITN was more common in men than in women. The ratio of pain sites located on the right side of the face was high in all groups. Patients with CTN were also prone to NVC on the asymptomatic side. Conclusion: By investigating TN subtype, it may be possible to elucidate the pathophysiology of TN. This would greatly improve treatment outcomes.

Scabies is a parasitic skin infection with intense itching. Scabies infection seriously impairs quality of life, while outbreaks in medical institutions cause financial losses. This study aimed to present the annual and seasonal trend of prevalence of scabies in the national population. Scabies cases were extracted from National Health Insurance Service database and its epidemiologic characteristics were assessed. To analyze the seasonality of scabies occurrence, temperature and humidity were included in the model as weather factors, and the per capita gross national income index was adjusted. The annual prevalence by age group was 0.56-0.69 per 1,000 persons until the age of 40 years and peaked at 3.0-4.1 per 1,000 persons in the age group over 80 years. The number of women diagnosed with scabies has been consistently higher compared to that of men since 2010. Mean number of cases diagnosed as scabies was lowest in spring, approximately 4,000 cases, when the average temperature was less than $5^{\circ}C$ at 2 months prior, whereas more than 6,000 scabies cases occurred in autumn when temperatures exceeded $25^{\circ}C$ at 2 months prior. This study presents the epidemiological characteristics and seasonality of all cases nationwide over 8 years and will help to establish control policies.

Background: Trigeminal neuralgia (TN) is one of the most painful disorder in the orofacial region, and many patients have suffered from this disease. For the effective management of TN, fundamental epidemiologic data related to the target population group are essential. Thus, this study was performed to clarify the epidemiological characteristics of TN in the Korean population. This is the first national study to investigate the prevalence of TN in Korean patients. Methods: From 2014 to 2018, population-based medical data for 51,276,314 subscribers to the National Health Insurance Service of Korea were used for this study. Results: The incidence of TN was 100.21 per 100,000 person-years in the year of 2018 in Korea, and the male to female ratio was 1:2.14. The age group of 51-59 years had the highest prevalence of TN. Constant increases in medical cost, regional imbalance, and differences in prescription patterns by the medical specialties were showed in the management of TN. Conclusions: The results in this study will not only help to study the characteristics of TN, but also serve as an important basis for the effective management of TN in Korea.

Canine lymphoma (cL) is the most common hematopoietic cancer in dogs. Various determinants have been evaluated to find the predisposing factors in both human and canine lymphoma. Due to common risk factors and similar pathways, cL is considered a potential model for non-Hodgkin lymphoma (NHL) in humans. In this case-series study, major hospitals in Tehran consented to take part in this study and between the years of 2020-2022, provided us with 52 cL cases which were approved by the attended pathologist. We designed a questionnaire and collected information about the dogs and their owners. Most of the owners were women, young (younger than 50 years old), had at least diplomas and interestingly were housewives or househusbands. Male dogs with middle to old age (more than 6 years) were mostly referred. The most common characteristics were neutered, normal BCS, purebred, urban but not industrial residence, previous tobacco smoke exposure but no history of previous fungicide or pesticide exposure. Also, most of them did not have any previous autoimmune or immunosuppressive diseases. Presented characteristics should be considered risk determinants but to approve their validity, they should be further evaluated in epidemiological studies.

목적: 사람 코로나바이러스(human coronavirus [HCoV]) 감염은 보통 경미한 임상 양상을 보이는 경우가 많으므로, HCoV에 대한 연구가 다른 호흡기 바이러스들에 비해 상대적으로 잘 이루어지지 않고 있다. 본 연구는 국내 소아청소년에서의 HCoV 역학 및 임상적 특성을 기술하고자 하였다. 방법: 2015년 1월부터 2019년 12월까지 서울대학교 어린이병원에서 수집한 호흡기 검체의 호흡기바이러스 검사 결과를 분석하였다. 다중 reverse transcription polymerase chain reaction을 이용하여 바이러스를 검출하여 역학을 조사하였고, 이전 건강했던 어린이에게서 HCoV가 검출된 경우에 한하여 임상 진단을 분석하였다. 결과: 총 9,589 개 검체 중 5,017개(52.3%)에서 1개 이상의 호흡기바이러스가 검출되었고 463개(4.8%)가 HCoV 양성이었다(OC43 2.8%, NL63 1.4%, 229E 0.7%). 3가지 유형 모두 겨울철(11월-2월)에 유행하였으며 유형별로 역학적 차이를 보였다. HCoV-OC43이 가장 흔하였으며 매년 겨울에 유행하였다. HCoV-NL63은 1월-3월과 11월-2월 사이에 유행하였다. 한편, HCoV-229E는 2015/2016 및 2017/2018 겨울에 격년으로 유행하였다. 연령군을 0-1세, 2-4세, 5-19세로 분류하였을 때, HCoV 감염의 빈도는 2-4세에서 가장 높았고, 5-19세에서 가장 낮았다. HCoV 양성 검체의 40.8%에서 다른 호흡기바이러스가 함께 검출되었다. 리노바이러스 및 호흡기세포융합바이러스의 동시검출률이 각각 13.2%, 13.0%로 높았고, 인플루엔자 바이러스는 4.3%로 낮았다. 이전에 건강했던 135 명의 어린이에게서 가장 흔한 임상 진단은 상기도감염(60.0%)이었고, 폐렴(14.8%), 크루프(8.1%), 세기관지염(6.7%) 순이었다. 크루프는 NL63 양성인 어린이의 임상 진단 중 17.0%를 차지했다. 결론: 본 연구는 소아청소년에서의 HCoV (OC43, NL63, 229E) 감염의 역학적, 임상적 특성을 기술하였다. 소아청소년에서의 HCoV 감염에 대한 지속적인 감시가 필요하며, 추가적으로 HCoV-HKU1을 진단 패널에 포함한다면 HCoV 감염의 임상역학적 특징을 파악하는 데 더 도움이 될 것이다.

Objective : The current study investigated the prevalence and clinical characteristics of sexual exhibitionism and frotteurism, which was conducted for the first time in Korea. Methods : Among 568 total subjects (mean age $19.28{\pm}5.0$ year), 109 were victims of sexual exhibitionism (19.2%, VSE) of which 57 were females (91.9 percent) ; and 57 were victims of sexual frotteurism (10.9%, VSF) of which 57 were females (91.9%). The participants completed the self-reported scale for epidemiological and clinical characteristics. Results : Incident frequencies of above two times of VSE and VSF were 49 (50.0%) and 20 (32.3%), respectively. Incident locations of VSE were school/office 37 (33.3%), street 28 (25.6%), and near home 20 (18.3%). Also, incident locations of VSE were inside of bus 12 (19.3%), subway 12 (19.3%), subway/bus station 8 (12.9%), near home 8 (12.9%), and school/office 7 (11.3%). Notifying rate of VSE and VSF to the police were 7.3% and 0%, respectively. Also, notifying rate of VSE and VSF to family or friends were 72.5% and 58.1%, respectively Conclusion : These results suggested that VSE and VSF had a common prevalence, which could be different from behavioral and emotional characteristics of a control group ; and the victims were shown to require an active intervention by supportive social system.
