In August 2001 we began to use WELPAS (a benzalkonium chloride solution) as part of our cost-containment drive, replacing self-made glycerol-added ethanol, which had been used for a long time to prevent nosocomial infections. Since then, blackish stains have become particularly noticeable here and there on the floorboards of the passageways in the hospital wards. The newly adopted quick-drying hand disinfectant was suspected as the culprit. To find the real cause of the dirt, we built a hallway similar to the real passageway for experiment. The disinfectant agents used were WELPAS, WELLUP (chlorhexidine gluconate), HIBISOFT (chlorhexidine gluconate), medicinal ethanol, cationic detergent solution, HIBITANE solution (chlorhexidine hydrochioride) and glycerol solution. These agents and distilled water were dropped on a limited area of the floor respectively for comparison of the degrees of dirt. The cationic detergent solution and WELPAS containing cationic detergent left blackish stains that were hardest to remove. From this finding, it was inferred that the cationic detergent solution was responsible for the dirt on the floor. So we decided to switch to a quick-drying hand disinfectant which does not contain cationic detergents. After considering economic benefit, we chose WELLUP which contains medicinal alcohol plus chlorhexidine gluconate and put it into actual use in October 2003. Since then, the hospitall floors have become unmistakalbly clean.

Formaldehyde is contained in various everyday products such as shampoos, detergents, leathers and papers, and is thought to be one of the important couses of clothing related contact dermatitis(ACD). The results about the minimum sensitizing concentrations of formaldehyde were different, and the concentration of 30 pg per gram of textiles was the least one. We measured the quantity of formaldehyde in 16 different types of textiles which are widely used in Korea to investigate whether the textiles contain an enough amount of formaldehyde to induce ACD and washing can reduce the amount of it. The results were as follows : 1. The quantity of formaldehyde ranged from 3 to 1246 pg per gram of textiles. 2. Three types textiles contained more than 100pg of formaldehyde per gram of textiles and 6 between 50 pg and 100pg. 3. 1.00% cotton, ramie and rayon contained the highest content of formaldehyde per gram fabric. 4. After washing, the average quantity of formaldehyde decreased to 60% of that, of pre-wash measure.

BACKGROUND: It is important to avoid the direct contact with water of detergents as possible for the treatment and prevention of hand eczema. OBJECTIVE: The purpose of this study is to evaluate the protective effect of skin protector, Marly skin on housewifes eczema, METHODS: The patients with hand eczema apply skin protector, Maly skin, four times a day on their both hands. They are evaluated with the scores of subjective symptor is(itch, dryness, smarting) and objective signs(erythema, scaling, fissures), and skin replica which are taken from the specified site are analysed by using an image analyser and, scanning electron micrascipe. RESULTS: 4 weeks after application of skin protector, there are statstically significant decrease of total clinical symptom scores. Scanning electron microscopic findings of the skin replicas show marked changes between the beginning and the end of the study. On quantive image analysis of the skin replicas, the length of fissure is a little decreased and the depth of rrows is slightly increased than before application of skin protector, but these are not statistically significant. CONCLUSION: Skin protector, Marly skin, has a protective effect on the development of hand eczema.

In order to prevent cross-infection, the sterilization of used and/or contaminated anesthetic- apparatus is still a difficult problem in clinical practice, particularly, following anesthesia for known advanced pulmonary tuberculosis cases. Therefore the antibacterisl activities of, an amphoteric detergent, Dodecyl diaminoethyl glycin hydrochloride (Hygien 51) were tested in vitro as a disinfectant against mycobacteria (M. tuberculosis H37 Rv, M. bovis, M. avium, M. tuberculosis H37 Ra, M. phlei, B.C.G.) The antimycobacterial activity tests were performed according to the modified Kolmer method. The testing organisms were cultured in Dubos broth at 37 degrees C, and the detergent, Hygien 51, was: diluted with sterile distilled water to 1,3,5 and 10%. One half milliliter of culture was pipetted into each tube containing 4.5 ml of diluted detergent, and at intervals of 3, 15, 30, 60, 120, 180 and 240 minutes, a 4mm loopful of the material was removed from each tube, and transferred to Ogawa media. The tests were carried out at two different temperatures, 20 degrees C and 50 degrees C. The subcultures were incubated at 37 degrees C for more than 8 weeks. The results were obtained as follows: 1) At room temperature (20 degrees C), all mycobateria, except M. bovis, were destroyed by treatment- with 10% solution of the detergent for more than 60 minutes. M. bovis was relatively sensitive to the detergent, and was killed by 5% solution for 30 min. and 10% for 15 min., but M. avium. was very resistant, and was not killed by 10% solution for 240 min. 2) By treatment with the detergent at 50 degrees C, the antimycobacterial activities of the detergent were highly increased. All mycobacteria were destroyed by 1% solution for 180 min, and by 10% for less than 30 min at 50 degrees C. In the comparison of the antibacterial activities against mycobacteria and other bacteria, it shows that mycobacteria are generally more resistant to the detergent, Hygien 51.

PURPOSE: This descriptive study was done to evaluate the attitude and practice of hand-washing by student nurses. METHOD: The subjects of the study were 463 senior and junior undergraduate student nurses and RN-BSN students. The questionnaire was developed by the researchers. Data were collected from Oct. 16 to Dec. 20. 2001. and analysed by SPSS/WIN. General characteristics, attitude and practice were analyzed by frequency and percentage and differences in attitude and practice according to grade and practice setting were analyzed with x2 test, t-test or ANOVA. RESULT: 1) The mean frequency of hand- washing was 6.63. Senior students washed more frequently than junior students. 2) The reasons for non-compliance were 'not being accustomed', 'forgetting', and 'not accessible' 3) The mean time for hand- washing was 23.79 sec., less than the stated appropriate time of 42.18 sec. 4) 90% of the students washed their hands 'after contacting excretions and contaminated items' and few washed 'before giving care to the client'. 5) Most students washed hands rotationally rubbing with soap and water. 6) While washing, they removed their rings more often than their watches. 7) Soap bar (52.8%) and paper towel (69.6%) were most frequently used as decontaminating agent and drying method, but detergent solution (74.2%) and paper towels (60%) were considered as the most appropriate agent and method. 8) Hand-washing was perceived important generally 'to protect from cross-infection', 'to protect one-self' and 'the most cost effective'. 9) All students responded nurses should practice 'hand-washing,'.

PURPOSE: The purpose of this study was to develop guidelines for cleaning of enteral nutrition bags by comparing the level of equipment contamination according to cleaning and disinfection methods. METHOD: This study was a true-experimental study, with 60 cases in total. Twenty cases each were randomly assigned to tepid water, detergent and brush, and disinfectant groups. The period of the experiment was March to April 2010, and enteral nutrition was given for 1 houre, 3 times a day at 7AM, noon, and 7PM for seven days. Enteral nutrition bags were cleaned after each feeding according to assigned cleaning and disinfection method followed by microbial cultures on 4th and 8th day before the 7AM feeding. RESULTS: After 3 days of feeding and cleaning, the level of contamination of bags was not significantly different among the three groups. After seven days, the level of contamination was significantly lower when bags were cleaned with detergent and brush or with disinfectant compared to cleaning with tepid water. CONCLUSION: In cases where enteral nutrition bags are reused for example, in home care settings, studying findings indicate that cleaning bags using detergent and brush or disinfectant is an effective way to prevent contamination of bags.

BACKGROUND: Daily bathing with antiseptic cleansers are proposed by some physicians as an adjunctive management of atopic dermatitis (AD). As atopic skin is sensitive, selection of cleansing products becomes a topic of concern. OBJECTIVE: Our purpose is to evaluate the pH of various antiseptic body cleansers to give an overview for recommendation to patients with AD. METHODS: Commonly bar and liquid cleansers consisted of antiseptic agents were measured for pH using pH meter and pH-indicator strips. For comparison, mild cleansers and general body cleansers were also measured. RESULTS: All cleansing bars had pH 9.8-11.3 except syndet bar that had neutral pH. For liquid cleansers, three cleansing agents had pH close to pH of normal skin, one of antiseptic cleansers, one of mild cleansers and another one of general cleansers. The rest of antiseptic cleansers had pH 8.9-9.6 while mild cleansers had pH 6.9-7.5. Syndet liquid had pH 7 and general liquid cleansers had pH 9.6. CONCLUSION: The pH of cleanser depends on composition of that cleanser. Adding antiseptic agents are not the only factor determining variation of pH. Moreover, benefit of antiseptic properties should be considered especially in cases of infected skin lesions in the selection of proper cleansers for patients with AD.
