Purpose: Infantile hepatic hemangioendothelioma (IHHE) is the most common type of hepatic vascular tumor in infancy. We conducted this study to review our clinical experience of patients with IHHE and to suggest management strategies. Methods: We retrospectively analyzed the medical records of 23 IHHE patients (10 males, 13 females) treated at the Asan Medical Center between 1996 and 2009. Results: Median age at diagnosis was 38 days (range, 1 to 381 days). Seven patients (30%) were diagnosed with IHHE based on sonographically detected fetal liver masses, 5 (22%) were diagnosed incidentally in the absence of symptoms, 5 (22%) had congestive heart failure, 3 (13%) had skin hemangiomas, 2 (9%) had abnormal liver function tests, and 1 (4%) had hepatomegaly. All diagnoses were based on imaging results, and were confirmed in three patients by histopathology analysis. Six patients were observed without receiving any treatment, whereas 12 received corticosteroids and/or interferonalpha. One patient with congestive heart failure and a resectable unilobar tumor underwent surgical resection. Three patients with congestive heart failure and unresectable tumors were managed by hepatic artery embolization with/without medical treatment. At a median follow-up of 29 months (range, 1 to 156 months), 21 (91%) patients showed complete tumor disappearance or >50% decrease in tumor size. One patient died due to tumor-related causes. Conclusion: IHHE generally has a benign clinical course with low morbidity and mortality rates. Clinical course and treatment outcome did not differ significantly between medically treated and non-treated groups. Surgically unresectable patients with significant symptoms may be treated medically or with hepatic artery embolization.

Korea's traditional aesthetic criterion changed with a new makeup culture that followed the social change caused by modernization. Such transitional features are well seen in the cosmetic advertisements of the 1920's and 1930's. To investigate the cultural characteristics and aesthetic-criteria changes of makeup culture at this period, this thesis analyzes cosmetic advertisements carried in newspaper media of the 1920's and 1930's from an aesthetic perspective. This study found that after the late 1920's, more diverse tones were used for face-powder makeup, collapsing the visual, powder-focused makeup which had been considered criteria for beauty, in combination with smelling and tactile senses such as scent or touch. Domestic makeup had the highest value attached to basic skincare in terms of the aesthetic effect via powder makeup; however, Japanese makeup still stressed the importance of color. Besides, particular facts were found as to social significance of makeup acts such as powder users' age group, safety, superiority and rivals of products, and appeal for makeup popularization. This thesis demonstrates how traditional female beauty appears in powder advertisements in the modern period and how it is related to present-day female beauty.

Infection has assumed increased importance as a cause of death among thermally injured individuals. Decreased treatment effectiveness and an increase in mortality are the hallmarks of nosocomial infection. Infection control is a monumental task that must be achieved to reduce mortalities. This was a retrospective study to survey the epidemiological features of nosocomial infections in a burn unit and to identify the possibilities for infection control. During the past 6 year 2 month period from July, 1981 to August, 1987, 306 burn patients were treated in the burn unit of university hospital. Among of these, 290 cases were the subjects of this study. The data were collected from the patients' records after discharge. All data collected were analyzed using percent, x$^2$-test, t-test with SPSS program. The results of this study are summariged as follows: 1) Infection rate was 40%. According to site, there were 67 cases of wound infection, 60 cases of post-operative skin graft infection, 20 cases of septicemia and 20 cases of donor site infection. As far as the burn size was concerned, the infection rate for patients whose burn size ranged 61 to 70%, was shown to be 100%, followed by the infection rate of 93.8%, for patients whose burn size ranged from 41~50%. As far as the period of time over which the infection developed, 5 to 7 days showed the highest frequency. Further infection was the main cause of deaths and complications. 2) Based upon the results obained by comparing the general characteristics, between a hospital infection-group and non-hospital infection group, there was a significant defference according to age, the time of the year when the accident happened, the place of accident or length of hospital-admission. And according to the result obtained by comparing the general characteristics of the burn, there was a significant difference according to burn size, burn depth, burn type, and burn site. And also based upon the result obtained by comparing the two groups according to method of treatment, there was a significant difference according to the use of antibiotics and to the type of wound-treatment, and for the 8 different binds of treatment related to infection, there was a significant difference for all. In conclusion, age, length of hospital-admission, burn size, burn type, burn site, burn depth, type of woundtreatment and the 8 different binds of treatment, which are related to burns, were shown to be the factors which affect the infection rate in burn patients.

Background: The aim of this study was to investigate demographic features, dietary habits, and some possible risk factors for being susceptible to breast cancer in Iranian women. Materials and Methods: A study of dietary habits and breast cancer was conducted among 53 Iranian women with histological confirmed disease and 40 matched controls. A dietary habits questionnaire was used to evaluate the pattern of selected food intakes. The risk of cancer was analyzed after adjustment for confounding factors. Age, weight, body mass index (BMI), waist circumference, educational status, parity, lactation, marital status, menopause, history of estrogen therapy, and family history of breast disease or cancer were assessed among participants. Special attention was given to the relationship between consumption of high fat meat, milk, yogurt and cheese as well use of frying oils for frying foods, use of olive/liquid oils for cooking, removing fat from meat and poultry, removing chicken skin and not use of mayonnaise as salad dressing and the risk of breast cancer. Moreover, salad, vegetable and fruit consumption, and eating outdoors owere investigated. Results: Our results revealed significant lower education and higher BMI and waist circumference levels in patients with breast cancer. There was significantly increased breast cancer risk in overweight women in comparison with normal weight (OR=2.91, 95%CI 1.24 to 6.82). High intake of fat dairy products including milk and cheese was found to be a statistically significant factor for increasing breast cancer risk in models adjusting for age, BMI and education. Use of olive/liquid oils for cooking and avoidance of mayonnaise as salad dressing are related to lower risk of breast cancer. The frequency of vegetable and fruit consumption was significantly lower in patients with breast cancer compared to healthy women. Conclusions: Dietary habits might be risk factors for breast cancer among Iranian women. Adoption of a prudent diet could be an appropriate strategy for preventing breast cancer.

목 적: 부식성 식도염은 화학적 화상으로 인하여 식도 협착 등과 같은 심각한 합병증을 초래할 수 있는 질환으로 예방과 함께 적절한 조기 치료가 중요하다. 그러나 부식성 식도염에 대한 국내의 연구는 그리 많지 않는 실정이다. 이에 저자들은 부식성 물질을 섭취하고 내원한 환아에서 임상 양상, 상부위장관 내시경 소견 및 식도 협착과 같은 합병증 발생 여부에 대해 알아보고자 본 연구를 시행하였다. 대상 및 방법: 1992년 1월부터 1999년 12월까지 전남대학교 병원 응급실과 소아과 외래에 부식성 물질의 섭취하고 내원한 31명의 환아를 대상으로 병력지를 후향적으로 검토하여 나이, 성별, 원인물질, 초기 임상증상 및 증후, 식도 협착의 발생빈도와 부위, 치료 및 경과에 대해 알아보았다. 또한 초기 내시경 검사를 시행했던 21명의 환아에서 손상부위와 정도를 알아보고 후기 합병증 발생과의 관계에 대하여 조사하였다. 결 과: 1) 평균 연령은 2세 3개월(12개월~9세 2개월)이었으며 남녀비는 2:1로 남아가 많았다. 환아의 대부분(27명)은 빙초산을 섭취한 후 내원하였다. 2) 내원시 임상 증상은 연하곤란이 17명(54.8%), 구토가 15명(48.3%), 피부 및 입술의 화상이 각각 14명(45.2%), 분비물 과다가 14명(45.2%), 경한 호흡기 증상이 10명(32.3%)이었고 흡인성 폐렴은 3명(9.8%)에서 관찰되었다. 3) 급성기에 상부위장관 내시경 검사를 시행하였던 21명의 환아 중 1도 손상은 8명, 2도 손상은 7명, 3도 손상은 2명에서 관찰되었다. 식도 손상의 부위는 식도 전장에 걸친 손상이 9례, 근위부 손상이 5례, 원위부 손상이 3례이었다. 21명의 환아 중 6례에서 위 점막 손상이 관찰되었다. 4) 식도 협착은 6명(19.4%)에서, 평균 5주에 발생하였으며 모두 빙초산 섭취 후 발생하였고, 황산차 밧데리 용액을 섭취한 환아 1례(3.2%)에서 위유문부 협착이 발생하였다. 1례에서 빙초산 섭취후 흡인성 폐렴으로 사망하였다. 5) 점막 손상의 정도와 식도 협착과의 관계를 보면 손상이 없거나 경미한 1도 손상에서는 모두 식도 협착이 발생하지 않았으나, 2도 손상을 보인 7명중 3명(42.9%)에서 3도의 식도 손상을 보인 2명 모두에서 식도 협착이 발생하였다. 결 론: 부식성 물질을 섭취하고 내원한 환아에서 조기에 시행한 상부위장관 내시경 검사는 식도 협착의 발생 가능성을 예측할 수 있는 유용한 검사로 생각되었으며, 적절한 치료에도 불구하고 높은 합병증의 발생을 보여 무엇보다도 우발 사고의 예방을 위해 가정에서 부식성 물질에 대한 철저한 관리가 필요하리라 사료되었다.
