BACKGROUND: CO laser emiis energy in the mid portion of the infrared spectrum at a wavelengt,h of 10,600nm. The CO laser is the workhorse laser in the treatment of cuianeous disease. With water as the chromophore(light-absorbing compound), CO laser light is highy absorbed in biologic tissue. Human body tissue comprises between 75% to 90% of water. The CO laser is superficially absorbed by tissue water, with little scatter, limiting penetration into the skin to less than 0.1 mm. The beam can be delivered with a large spot size and low power density(defocus mode) or focused tightly with great power density(focused mode). AS A RESULT: the CO laser may be used both to vaporize and to cut tissue while coagulating blood vessels, providing a relatively bloodless su gical field. OBJECTIVE: The purpose of this study was to evaluate the therapeutie effect of the CO laser on benign cutaneous tumors. MEHTODS: 114 cases of benign cutaneous tumors treated with the CO laser between October 1987 and September 1992 were subjected to detailed analysis, The CO later is Pizer Laser system(U.S.A., Ca) Model 20-C CO. The laser produces power output that ranges from 0 to 25 W of continuous wave. Spot size is variable, between 0.3mm and 2mm. RESULTS: 1. Angiofibromas and seborcheic keratoses showed very good response(95.3%, 92.8% ). 2. Syringomas showed a good esponse(82.8%). 3. Epidermal nevus and trichovpitheliomas showed a fair response(58.5%, 60%). 4. There were hypertrophic scars(10.5%) and transient hypopigmentation. CONCLUSION: The Co laser was a very effective modality for the treatment of benign cutaneous tumors such as angiofibromas, seborrheic keratosis and syringomas.

PURPOSE: Neonatal surgical conditions affecting the gastrointestinal tract are varied, can affect any part of the intestinal tract, and frequently require urgent surgical intervention. Unfortunately, nonspecific and overlapping symptomatology exists among the conditions affecting the intra-aMominal intestinal tract and requires of the evaluating physician a thorough understanding of their pathophysiology. So we studied signs and symptoms, frequency and incidence, ages at diagnosis, and diagnostic method of the neonatal gastrointestinal obstructions. METHOD: We reviewed retrospectively the charts of patients, who had been diagnosed as gastrointestinal obstruction during the neonatal period, and had been admitted to Gyeongsang National University Hospital from Feb. 1988 to Feb. 1997. RESULT: Total 77 cases were enrolled in this study. There were 59 rnales (76.796) and female 18 cases (23.4%). The male to female ratio was 3.28: 1. Twenty-two cases of imperforate anus (28.6%), 18 cases of hypertrophic pyloric stenosis (23.4%), 15 cases of congenital megacolon (19.5%) were observed. Other diseases causing the neonatal gastrointastinal obstruction were annulus pancreas (7.8%), jejunal atresia (6.5%), duodenal atresia (1.3%), duodenal web (2.6%), ileal atresia (2.6%), midgut volvulus (2.6%), intussusception (1.3%), and trachoesophageal fistula (2.6%). The rnost common symptom was vomiting with 32 cases (41.6%), followed by abdominal distension with 31 cases (40.3%), absence of anus with 17 cases (22.1%), and delayed meconium passage with 9 cases (11.7%). Associated other anomalies were observed in 18 cases (23%). Imperforate anus was seen with the highest rate of associated anomalies. The most common associated anomaly was the cardiac anomaly. Colon study (26%), physical examination (24.7%), abdominal sonography (15.6%), upper GI series (11.7%), and simple abdomen (9.1%) were diagnostic in the neonatal gastrointestinal obstructions. Seventeen cases (22%) were died before or after the surgical intervention. CONCLUSION: Neonatal gastrointestinal obstructions were associated with the high mortality rate. Abdominal distension and vomiting were the specific symptoms of neonatal gastrointe- stinal obstructions. Extensive search for the associated anomalies are reqiured because of its high frequency in the patients of the neonatal gastrointestinal obstructions. Thorough physical examination, colon study, abdominal sonography, upper GI series, and simple abdomen were essential in the diagnosis of the neonatal intestinal obstructions.

Allergic contact dermatitis to topical agents mostly results from vehicles and preservatives and rarely from the active ingredients. Ribavirin, an active ingredient of Viramid® cream, is a synthetic nucleoside derivative with broad spectrum activity against a wide variety of DNA and RNA viruses. We report an 18-year-old woman, who had a perioral edematous patch with exudative crusts after topical application of Viramid® cream (nsung pharmaceutical Co., Korea) for the treatment of herpes labiahs. A patch test showed that the sensitizer was ribavirin, the active ingredient of the antiviral agent, Viramid® cream.

PURPOSE: The purpose of this study was to identify the research trends and instruments for assessment of sleep quality in Korea. METHODS: 66 quantitative research reports published from 2000 to March 2009 in Korea were selected from 5 databases: RISS4U, KISS, KISTI, DBpia, and the National Assembly Library and were analyzed according to criteria such as publication years, type of journal, participants, study fields, research design, participants, key words and instruments for assessment. RESULTS: Research in sleep quality has been rapidly increasing in recent years. More than half of the research analyzed was conducted in nursing. The majority of research methods were survey and correlational research. Patients with chronic illness and the elderly were the major subjects in those researches. Most research was performed based on hospitals and communities. The types of variables tested for their relation and influence on sleep quality were quite limited. With respect to the instrument used for assessing sleep quality, most studies did not consider whether or not the validity of their instrument had been established. CONCLUSION: It is recommended to conduct clinically applicable interventional research with an experimental design and to develop a reliability and validity established sleep quality instrument for Koreans.

PURPOSE: To evaluate the clinical usefulness of the 10-prism-diopter (PD) fixation test in the diagnosis of amblyopia. METHODS: The study comprised 132 children (42 normal, 90 amblyopes) who underwent the 10-PD fixation test and stereoacuity test. The sensitivity, specificity, false-positive and false-negative rates of the 10-PD fixation test were analyzed according to the clinical diagnosis. RESULTS: The 10-PD fixation test sensitivity was 86%, the specificity was 61%, the false-positive rate was 17% and the false-negative rate was 24%. Data showed agreement between the 10-PD fixation test and the stereoacuity test (gamma=0.737, p=0.000). The results in the 10-PD base-down test and base-out test also showed agreement (gamma=0.779, p=0.000). CONCLUSIONS: The 10-PD fixation test is a simple and useful method in detecting amblyopia.

PURPOSE: The purpose of this study was to explore the yangsaeng level in a health management way of an aged women in rural area, and to offer basic material for the development of community's public health service. METHODS: The subjects were 144 aged women who participated voluntarily in the questionnaire. The data were collected from January to February, 2008 with a self-administered questionnaire. Data were analyzed by SPSS 13.0 win program for finding frequency, percentage, mean, standard deviation, ANOVA and Tukey. RESULTS: The average age of workers was 72. Total yangsaeng level was 3.08+/-.33, highest yangsaeng factor was Activity & Rest Yangsaeng of 3.55+/-.46 and lowest yangsaeng factor was Season Yangsaeng of 2.43+/-.75. The total Yangsaeng level was the significant difference in monthly incomes(F=4.046, p=.047). CONCLUSION: Considering the results above, the yangsaeng level of aged women is affected by the age, education level, a monthly income etc. Therefore, for health promotion plan of aged women, consider that their age, educational level, economic level ect, and systematic education for promotion of health is necessary.

We analyzed the factors of importance for nonunion in series of 91 open fractures of tibial diaphysis which were treated with external fixation. Factors analyzed included, age and sex of the patients, the mechanism of injury, the amount of soft tissue damage, the grade of comminution, the level at which the tibia was fractured, the presence of an intact fibula, the presence of the multiple injuries, the type of the external fixation used(AO external fixator, EXTOR; monotube external fixator, Ilizarov), and the need to supplement the stability of the reduction. We found that the amount of soft tissue damage and comminution of the fracture played a role in the development of the nonunion.
