Polyethylene wear is one of the major problems following total knee arthroplasty. Many factors affect the degree and the pattern of polyethylene wear. We experienced three cases of early catastrophic poly- ethylene wears. All cases showed flexion contracture with severe genu varum deformity and total knee arthroplasty was performed with Advantim total knee prostheses in all cases. Postoperatively, bony align- ment and ligament balancing were good in all cases. However, in 12 to 22 months later, lateral subluxa- tion and valgus instability were developed with early catastrophic polyethylene wear especially in the medial compartments. Flat surface geornetry of polyethylene might be responsible for the development of lateral subluxation and early catastrophic wears. From these experience, we concluded that the mediolat- eral as well as anteroposterior dishing is essential for the stability of the artificial joint and prevention of early rapid wear of polyethylene articular inserts following total knee arthroplasty.

PURPOSE: Medical students are exposed to various interpersonal relationships with patients, faculty and colleagues. Therefore, a clear understanding of their personality types and interpersonal problems is vital in creating an appropriate educational program for medical students. This study intends to explore the characteristics of interpersonal problems based on medical students' personality types. METHODS: The Myers-Briggs type inventory(MBTI) and Korean Inventory of Interpersonal Problems were used to assess the first-year medical students at Yonsei University College of Medicine, 2006. RESULTS: The personality types focusing on the interpersonal domain showed that the medical students could be categorized into four types: analytical type(47.2%), driving type(30.3%), amiable type(12.4%), and expressive type(10.1%). The characteristics of interpersonal problems data were within normal range. The relationship between the personality indicator and the characteristics of interpersonal problems is statistically significant in extraversion-introversion. CONCLUSION: Our results demonstrate that the personality factors of medical students are correlated to the interpersonal problems they face. Thus, educational programs that take into account personality types and characteristics of interpersonal problems are crucial in providing high-quality medical education.

A 32-year-old male patient with uncontrolled diabetes mellitus was affected with hyperlipoproteinemia type II His skin lesion showed yellowish papulsr tuberoruptive xanthoma on forearm, shoulder, elbow and knee. Besides skin eruption, he showed abnormal liver function test and right bundle branch block on EKG. The laboratory examinations revealed increase of serum cholesterol, triglycerides. and fasting blood sugar, and slight turbid color of fasting blood serum which had been kept standing at 4C for 24 hrs. On the agarose electrophoresis, bands of different densities of LDL and VLDL in beta and pre-beta position Were noted. Authors discussed here about laboratory characteristics, clinical manifestations and differential diagnosis of hyperlipoproteinemia type II and III.

The purpose of this study is to investigate whether nicotinic acid (NA) and nicotinamide (NAM) reduce the Alzheimer disease (AD)-related gene expression in brain tissues of amyloid beta (Aβ)-injected mice. Male Crj:CD1 (ICR) mice were divided into 6 treatment groups; 1) control, 2) Aβ control, 3) Aβ + NA 20 mg/kg/day (NA20), 4) Aβ + NA40, 5) Aβ + NAM 200 mg/kg/day (NAM200), and 6) Aβ + NAM400. After 1-week acclimation period, the mice orally received NA or NAM once a day for a total of 7 successive days. On day 7, biotinylated Aβ42 was injected into mouse tail vein. At 5 hours after the injection, blood and tissues were collected. Aβ42 injection was confirmed by Western blot analysis of Aβ42 protein in brain tissue. NAM400 pre-treatment significantly reduced the gene expression of amyloid precursor protein and presenilin 1 in brain tissues. And, NAM200 and NAM400 pre-treatments significantly increased sirtuin 1 expression in brain tissues, which is accompanied by the decreased brain expression of nuclear factor kappa B by 2 doses of NAM. Increased expression of AD-related genes was attenuated by the NAM treatment, which suggests that NAM supplementation may be a potential preventive strategy against AD-related deleterious changes.

PURPOSE: This study was done to provide data that would contribute to effective task performance in clinical nursing and development of nursing professional by understanding job stress, job satisfaction and organizational commitment according to Life Organization (LIFO) behavior types of novice nurses. METHODS: This study was a cross-sectional survey and the participants were 313 novice nurses who worked in one university hospital located in the city of Gwangju. Data were collected through the structured questionnaires that included general characteristics, job stress, job satisfaction, and organizational commitment scales. Collected data were analyzed using descriptive statistics, and ANOVA with SPSS/WIN 19.0. RESULTS: Regarding job stress according to LIFO behavior types of novice nurses, there were statistically significant differences between the favorable situation and the unfavorable situation. There were also statistically significant differences regarding the organizational commitment according to LIFO behavior types. CONCLUSION: The results indicate a difference in behavior patterns of novice nurses that suggest a need for education in order to reduce stress from the job and enhance organizational commitment by developing each nurse's preferred pattern and compensating for unfavorable patterns, as well. There also needs to be nursing resources that take into consideration behavior patterns of novice nurses.

PURPOSE: This study was done to explore the meaning and nature of life world for adolescents with epilepsy. The hermeneutic phenomenological method which was developed by van Manen was used. METHODS: Participants were four boys and five girls, ages 13 to 18 being seen in a neurology outpatient department. Data were collected from iterative work with in-depth interviews from during the period from February to September, 2010. Contents of the interviews were tape-recorded with participant consent. RESULTS: Essential themes that fit into the context of the 4 existential grounds of body, time, space and other people were: an illness that makes a hurt in one's heart rather than one's body, a change in the body that is not controllable, a future like thick fog, everyday life trapped in illness, a change of relationships, learning how to live with an illness. CONCLUSION: Findings reveal the life world of the adolescents is affected to varying degrees by the epilepsy. It is important for nurses to identify and address developmental issues and effects of the illness and to support reorientation in a disintegrated life situation. The result of this study will provide nurses with insights into these experiences and should help promote empathetic care.

Gestational trophoblastic tumor is one of the curable disease, but metastatic trophoblastic tumor still shows high mortality rate because of resistance to the chemotherapy. Choriocarcinoma may occur after an any type of human pregnancy. The incidence of choriocarcinoma following term pregnancy is very uncommon, and such tumor appears to follow a more aggressive course with more extensive metastatic spread and is less responsive to chemotherapy resulting in a poorer prognosis. Choriocarcinoma presenting as postpartum hemorrhage, and spontaneous tumor perforation with intra-abdominal hemorrhage is even rarer, requiring emergency laparotomy. We had experienced one case of metastatic choriocarcinoma following term pregnancy that required emergency total abdominal hysterectomy due to uterine perforation and hemorrhage. So, we report this case with brief review of literatures.

PURPOSE: This study was conducted to assess the nutritional status of female marriage immigrants attending Korean language class in Gwangju, Korea by analyzing daily food and nutrient intake. METHODS: Eighty-three female immigrants completed a survey. Anthropometric measurements were obtained, and dietary food intake was assessed using a 1-day 24 hour recall method. RESULTS: The average length of residence in Korea was 5.3 years, and mean age of subjects was 31.0 years old. The home countries of subjects were Vietnam (50.6%), China (24.1%), Philippines (13.3%), and others (12%). Due to the length of residence, there were significant differences in body weight (p < 0.05), BMI (p < 0.05), percent body fat (p < 0.05), and diastolic blood pressure (p < 0.05). The subjects who were 30~49 years old consumed more vegetables and less seaweed than the subjects who were 20~29 years old. The other kinds of consumed foods were similar among groups in different age groups or lengths of residence in Korea. Average energy intake of subjects was 1,641.0 Kcal. The group with less than 5 years of residence showed higher cholesterol intake than the group with 5 or more years of residence in Korea (p < 0.05). There was no significant difference in nutrient intake between the groups of different age or length of residence. There was a positive association among dietary cholesterol intake and consumption of eggs, milk. and dairy products, and blood pressure. CONCLUSION: The study shows that length of residence affects rate of obesity and nutritional status. Further extensive research is needed to understand the effect of dietary changes and nutritional status of female marriage immigrants as well as for their successful adaptation to develop a more active and long-term nutrition education program.
