Purpose: Poor living conditions such as overcrowding and sharing a bed are reported to be significant risk factors for H. pylori infection throughout childhood. We investigated the prevalence of Helicobacter pylori infection in Korean athletes who are obliged to live together in training camps over six months a year. Methods: Blood sampling and surveying through questionnaire were performed on 440 regular high school students (228 boys and 212 girls) and 220 athletes (148 boys and 72 girls) of a physical education high school. We measured serum IgG Ab to H. pylori in order to compare the prevalence of H. pylori infection between normal adolescents and athletes. In addition, we conducted a nutritional analysis and questionnaire survey for socioeconomic status in order to compare other risk factors that might influence H. pylori infection between groups. Results: The prevalence (43.2%) of H. pylori infection in athletes was higher than that (22.7%) in the controls. No significant differences in the nutritional factors or socioeconomic status, such as Hollingshead index, type of house, and crowding index, were found between the groups. Multivariate analysis showed that crowding and the difference in school type were the significant predictors of H. pylori seropositivity after controlling for dietary and socioeconomic factors. Conclusion: Living together in training camps might be a significant risk factor for H. pylori infection in athletes. 목적: 침대를 함께 사용하고 밀집된 공간에서 생활하는 것이 H. pylori 감염을 일으키는 의미 있는 위험 인자로 알려져 있다. 저자들은 훈련을 위해 합숙해야 하는 청소년 운동선수들에서 H. pylori 감염의 유병률을 조사하고 이를 일반 학생들과 비교해 보고자 하였다. 방법: 일반 고등학교 440명(남학생 228명과 여학생 212명)과 체육 고등학교의 운동 선수 220명(남학생 148명과 여학생 72명)을 대상으로 정맥 채혈과 설문지를 통한 조사가 이루어졌다. 첫째, 일반 학생과 운동 선수들의 H. pylori 감염의 유병률을 비교하기 위해 H. pylor에 대한 혈청 IgG 항체를 검사하였다. 둘째, H. pylori 감염에 영향을 미칠수 있는 위험 인자를 비교하기 위해 두 군간의 섭취하는 음식에 대한 영양 분석과 사회 경제적인 상태에 대한 설문지 조사가 시행되었다. 결과: 1) 육상 선수들의 H. pylori 감염의 유병률(43.2%)이 대조군(22.7%)에 비해 의미있게 높았다. 2) 두 군간에 영양섭취 및 Hollingshead 지표, 주택소유 여부, 혼잡지표 등의 사회경제적인 상태의 의미있는 차이는 없었다. 3) 다변량 회귀분석상 학교의 차이와 혼잡지표가 H. pylori 감염에 영향을 주는 유의한 인자였다. 결론: 훈련 캠프의 합숙생활이 청소년 운동 선수들에서 H. pylori 감염을 일으키는 의미있는 위험 인자가 될 수 있다.

Amelanotic maliganat melanoma is a comparatively rare disease. It accounts for 1.8∼8.1% of all malignant melanoma. It is sometime difficult to diagnose amelanotic malignant melanoma because there is no pigmentation, clinically. Polypoid melanoma is a variant of nodular melanoma, which in depth seldom reaches the reticular dermis. The main part of the tumor is located above the nearby epidermis, raised in the form resembling cauliflower. We report a rare case of amelanotic malignant melanoma with polypoid feature in a 78-year-old woman who presented a single bright red nodule on the left thigh.

Blue nevus is a neoplasm composed of pigmented dendritic dermal melanocytic cells in the reticular dermis. The lesion clinically presents as a well dermacated cerulean-blue or bluish black colored papule or plaque that usually measure less than 1 cm in diameter. Pilar sheath acanthoma is a rare, benign follicular hamartoma commonly affecting middle-aged and elderly individuals. It is characterized by a small, solitary, skin colored papule situated on the head and neck, particularly around the upper lip. We report a rare case of a blue nevus associated with a pilar sheath acanthoma in a 26 year-old man presented with a bluish papule on the neck. (Korean J Dermatol 2013;51(10):814∼816)

Background: The most of typical seborrheic keratoses (SKs) can be clinically differentiated with ease from other dermatoses. However, its differential diagnosis can sometimes be difficult and recently reported cases clinically suggest that SKs with the skin biopsy result being some other diseases can bring on the need for further evaluations. Objective: The aim of this study is to examine the diagnostic yield in submitting clinically diagnosed SKs which showed single discoid lesions of the face for routine microscopic examinations. Methods: We conducted a retrospective review of cases for histological examinations with a clinical diagnosis of SKs or with a differential diagnosis that includes SKs which shows single discoid lesion of the face. A total of 94 pathology reports containing a diagnosis of SKs in the clinical information field were identified. The accuracy of the clinical diagnosis and clinic histopathological correlations were studied. Results: In this study, 45.7% of patients was clinically assumed to have SKs but turned out to be some other diseases according to the histopathology test results - a total of 19 cases (44.2%) with some considered to be precancerous (actinic keratosis 25.6%, benign lichenoid keratosis 16.3% or cancerous (basal cell carcinoma 9.3%, squamous cell carcinoma 4.7%). Conclusion: Lesions suggested to be SKs need more examinations and lesions of atypical clinical appearances which cannot completely exclude the possibility of precancerous or malignant lesions are strongly recommended for skin biopsies.

Squamous cell carcinoma on the lip is a common oral malignancy, and it is responsible for >30% of all oral squamous cell carcinomas. Numerous factors have been implicated in the development of squamous cell carcinoma on the lip, but the most frequently identified risk factors include chronic exposure to ultraviolet radiation. Squamous cell carcinoma on the lip is more prevalent in elderly men, with a male-to-female ratio of 5:1. We report an interesting case of squamous cell carcinoma mimicking herpes simplex on the lip in a 35-year-old woman who presented with erythematous grouped vesicles on the upper lip.

In this study's contents are structural design for submarine's pressure hull structural strength to secure a stable. The most stable for at least the surface of the pressure hull is sphere. Speed on the hydrodynamic aspects of the vessel, the efficiency and production of space, because of the cylindrical structure is applied against. The material of the pressure hull HY100 was used for weight loss. Submarine pressure hull is composed of several different structural elements. This failure mode is complex and the interaction between the components should be reviewed.. In this study, designed the submarine pressure hull structure design of the core driven mainly Approximation, Empirical, FEM analysis was verified in parallel.

Background: Melasma has been shown to have a significant emotional and psychological effect on affected patients. Objective: The aim of this study is to evaluate the usefulness of the Melasma Quality of Life Scale (MELASQOL) as compared to Dermatology Life Quality Index (DLQI). Methods: A total of 74 female patients of melasma were asked to complete a questionnaire of MELASQOL, DLQI, and additional demographic data. The degree of melasma was determined on the basis of clinical photos by the investigator using the Melasma Area and Severity Index (MASI). Results: The mean age of these patients was 46.3±8.5 years. The mean MELASQOL score was 39.8±16.03 and the mean DLQI score 6.7±4.41. The MASI and MELASQOL scores showed statistically significant correlations (p<0.01, Pearson correlation=0.373). But, there was no statistically significant correlation between MASI and DLQI scores (p>0.05, Pearson correlation=0.129). Also, multiple linear regression model shows that the correlation of MASI and MELASQOL (standardized coefficient=0.367, p<0.001) is higher than the MASI and DLQI (standardized coefficient=0.139, p>0.05). Conclusion: We suggest that the MELASQOL could be more relevant and useful than DLQI when evaluating the quality of life for melasma patients. It is presumed that the MELASQOL might be helpful in guiding the patient to appropriate treatment methods and in tracking patient`s satisfaction levels.
