BACKGROUND: Lipids of horny layer forming multiple lamellar structure in the intercellular space acts as a skin barrier having a primary protective function and keeps softness and flexibility of the skin by absorbing and maintaining moistures. Among the intercellular lipids, ceramides mainly contribute to this important role. In xerotic eczema, atopic dermatitis, psoriasis, ichthyosis, and experimentally induced scaly lesion showing dryness and scales, the amount of ceramides is decreased or distribution of ceramide is changed. In addition to lipids, free amino acids, a component of NMFs, serve as a water retainer and are decreased in ichthyosis or experimentally induced scaly lesion. Hand eczema has dry and scaly lesion showing impaired skin barrier and low water content. So, changes of ceramides or free amino acids can be considered in the lesion of hand eczema. OBJECTIVE: The purpose of this study was to confirm the relationship between the development of hand eczema and changes of ceramides or free amino acids. METHOD: The lipids and free amino acids in scales from lesion of hand eczema were analyzed by using high performance thin layer chromatography and amino acid analyzer. RESULTS: Amounts of total lipids extracted were 0.63+/-0.33 microgram/cm2 in hand eczema and 0.44+/-0.26 microgram/cm2 in control. There was no difference between the two groups. Cholesterol sulfate, glucosyl ceramide, cholesterol, triglyceride, sterol ester, and n-alkane showed no difference between hand eczema and control. But ceramides were significantly decreased in hand eczema(11.0+/-5.5%) compared with control(21.4+/-8.0%)(p<0.05). Especially, ceramide type IV was significantly decreased in hand eczema (6.6+/-5.3%) compared with control(15.6+/-6.2%)(p<0.05) but ceramide type III in hand eczema did not differ from control. Amounts of total free amino acids in 10mg of scale were 10.4+/-3.1nmol in hand eczema and 9.5+/-3.0nmol in control. There was no significant difference between the two groups. CONCLUSION: Dry skin and scales in hand eczema are related to the decrease of total amount of ceramides and ceramide type IV than amino acids in horny layer. To clarify the exact pathogenesis of hand eczema, further investigations on all types of ceramides and their defect in the process on biosynthesis of ceramides will be necessary.

This study was alone to identify the meaning and the essence of the menopause experience by means of the Colaizzi's phenomenological method. The participants were eight women, 48-60 years old, who were experiencing perimenopause or postmenopause. They were selected using a theoretical sampling technique. Data were collected through in-depth interviews from April 6 to May 20, 1999. The interviews took from 40 to 90 minutes. Interviews were tape- recorded and analyzed using the constant comparative method. Significant statements from data were extracted. From these formulated meanings, 18 themes, 8 clusters of themes and 3 catagories were constructed. Final descriptions were found to be valid through the interviewee validation process. Essential themes of the menopausal experience which emerged were "coming of change", "inclined to deny the in mind", and "adapted life". Menopause, as coming of change was the turning point in the women's life cycle acompaning changes, in body and mind and marital life changes. Especially, the unpredictable menopausal changes were an opportunity to hide the fact of menopause and not to talk with anybody. Such a phenomenon reflected on the psychological attributes of menopausal woman such as an inclination to deny in the mind. Their experiences of menopause as adapted life were generally regarded as signalling the end of fertility and were interpreted as a natural developmental process that indicates a life transition. In conclusion, participants depicted the menopause as a natural stage in the life cycle. In order to help women have a positive life change and self accomplishment, nurses need to understand the essential themes of the menopausal experience. Thus, the importance of an open approach in eliciting the phenomena of menopause cannot be overemphasized. In conclusion, the results of this study suggest that exercise program is one of the effective interventions to improve the self-efficacy and also to lower the fatigue in the sample of female college students.

PURPOSE: To identify age, gender, medication, seasons and place of fall, and areas of the fractures from the fall among the hospitalized elderly patients in order to provide the basic data for future fall prevention program for the elderly. METHODS: This study was conducted for 106 elderly patients admitted into a university hospital by fractures from the fall during the period from January 1, 1999 to December 31, 1999. Data on the age, gender, medication, season and place of the fall, areas of the fracture were collected based on their medical records. RESULT: The age range of the subjects were from 60 to 96 years old. The subjects were aged between 60-69 years old 49(46.2%), between 70-79 years old 31(29.2%), between 80-89 years old 24(22.6%), and over 90 years old 2(1.9%). Male patients comprised was 34(28.3%), while female patients comprised 76(71.7%). The fall occurred in Winter most frequently 34(32%). The place of the fall included room 81(76.4%), streets 13(12.3%), bathroom 6(5.7%), stair 4(3.8%), and mountain 2(1.9%). Twenty-two subjects (20.8%) had medication regularly, while 84 subjects (79.2%) had no medication. The areas of the fracture from the fall included upper extremities 20(18.9%) and lower extremities 86(81.1%). Radius fracture (7.5%) was the area where the fracture occurred most frequently in upper extremities and femur fracture (52.8%) was the area where the fracture occurred most frequently in lower extremities. A significant difference was found in the fracture area by age, season and place of the fall (p<.05). No significant difference was found in the fracture area by gender and medication. In all age groups, seasons and places of the fall, occurrence of fracture in lower extremity was significantly higher than that in upper extremity.

BACKGROUND: The purpose of this study is to evaluate the evidence for the effectiveness of different isolation policies in reducing the incidence of methicillin-resistant Staphylococcus aureus (MRSA) infection in hospital in-patients. METHODS: We prospectively evaluated the effectiveness of an isolation policy on transmission of MRSA in the 745-beds hospital. First period, all patients with MRSA (March - July 2000) were not isolated Second period, strict isolation policies were performed (August 2000 - January 2002). All patients with MRSA were isolated in separated room, hand hygiene using alcohol handrub, gowning and g1oving, apply of MRSA notice sticker, criteria in isolation remove, separated disinfection and wastement. Third period, semi strict isolation policies were performed (February 2002 - August 2005). Some patients with MRSA were isolated in separated room and others were admitted in general ward for bed shortage. Only some practices were performed in hand washing and separated disinfection in general ward. RESULTS: The rates of MRSA nosocomial infection per patients during 1st, 2nd, and 3rd surveillance were reported 0.56, 0.23, and 0.42 (P<0.05). Patient-days rate of MRSA nosocomial infection during 1st, 2nd, and 3rd surveillance were reported 0.62, 0.27, and 0.38 (P<0.05). CONCLUSION: With many different isolation policies, it was possible to reduce nosocomial infection of MRSA. In this study, strict isolation policies (2nd period) were the most effective practices in reducing MRSA infection.

BACKGROUND: Massive bleeding, inability to identify important landmarks and structures, and necessity for a blood transfusion have been the usual problems of hemangioma excision. OBJECTIVE: We introduce a CO2 laser excision technique as a surgical method for the treatment of hemangioma of the lips and demonstrate its benefits. METHODS: In 4 patients with nevus flammeus of hemiface and accompanying hemangioma of the lips, excision of the hemangioma was performed using a focused beam from a CO2 laser under local anesthesia. RESULTS: Excellent to good results were achieved with minimal blood losses in all patients. No or minimal post-operative pain and edema and no significant complications were observed. CONCLUSION:The CO2 laser excision technique is recommended since it renders less textural change, greater volume reduction, hemostasis and an overall good cosmetic outcome than defocused modes or conventional scalpel surgery.

PURPOSE: This descriptive study aimed to compare the perception of the acceptable foods for the neutropenic diet between nurses and patients by food type. METHODS: The participants were 225 nurses working at chemotherapy wards and 71 patients in chemotherapy treatment. Data were collected with a self-administered questionnaire from January 2 to February 24, 2012, and analyzed with SPSS 12.0 program using descriptive statistics and the chi2-test. RESULTS: Eighty-eight point eight percent of nurses and 76.1% of cancer patients thought the patients needed the neutropenic diets. The most important decisional criteria to determine dietary restriction was neutrophil count for nurses and food type for patients. The two groups showed significantly different allowance to raw fruits and raw vegetables, sterilized canned juice, fried vegetables, yogurt, uncooked tofu, salted fish, cooked fish, cooked shellfish, uncooked grain powder, jellified food, home-made bread/cookies, nuts including peanuts, instant coffee or tea and tea brewed. In general, patients were more permissive about the neutropenic diet than nurses. CONCLUSION: It is recommended to consider patients' preference as well as nurses' professional knowledge and publish standardized clinical diet guidelines for neutropenic patients with collaboration between nurses and patient representatives.
