A 62-year-old farmer was admitted to our department because of second degree chemical burns of both buttocks ten days following accidental contact with Gramoxone, a weed killer. He was treated with oral antibiotics and cold compresses and discharged after the burned area were reepithelialized. Laboratory findings were within normal limits for three weeks. Although lung fibrosis, hepatic and renal failure can be caused by repeated absorption of paraquat (Gramoxone) through injuried skin, systemic absorption through normal skin has not been reported. During the four month follow up period there were no systemic problems nor recurrence of skin lesions. We report herein a case of chemical burns induced by Gramoxone, which is probably an occupational dermatosis of farmers handling weed killers.

There are many controversies concerning therapeutic guidelines for the treatment of Kienbock's disease. We experienced 17 cases of stage II or III Kienbock's disease(Lichtman's classification), which were treated with triscaphe fusion from March 1983 to March 1992. The mean Follow-up peri- od was 25 months. The purpose of this study is to evaluate the clinical and radiological result of triscaphe fusion of 17 cases of Kienbock's disease. 1. The pain was relieved in all cases, but range of motion was not improved after operation. 2. The postoperative results of triscaphe fusion were evaluated by Licthman's method. 9 cases (53%) were rated as satisfactory and 8 cases as unsatisfactory. 75%(3 cases of 4) were rated sat isfactory in IIIA a group and 22%(2 casaes of 9) were rated satisfactory in IIIB group. 3. The psudoarthrosis was noted in 2 cases of 17.

PURPOSE: To evaluate the differences in dry eye and meibomian gland dysfunction (MGD) by comparing ocular surface status before and after wearing an orthokeratologic (OK) lens and rigid gas permeable (RGP) lens made of the same material. METHODS: The ocular surface and meibomian gland statuses of 12 eyes of 12 OK lens wearers (OK lens group) and 16 eyes of 16 RGP wearers (RGP lens group) were evaluated before and 1 and 3 months after lens wearing. Ocular surface disease index (OSDI), tear film break-up time (TBUT), Schirmer's test I, and ocular surface staining score were evaluated for ocular surface parameters. Meibomian gland function was evaluated by assessing lid margin abnormality, meibomian gland expressibility, and meibum quality. RESULTS: TBUT and ocular surface staining score after 1 and 3 months of wearing an OK lens were significantly aggravated (p= 0.004, p < 0.001). The MGD grade, lid margin abnormality, meibomian gland expressibility, and meibum quality were aggravated after 1 and 3 months of wearing an OK lens (p < 0.001, p < 0.001, p < 0.001, p= 0.002). After 1 and 3 months of wearing an RGP lens, OSDI, TBUT, and ocular surface staining score were aggravated (all p < 0.001). The MGD grade, lid margin abnormality, meibomian gland expressibility, and meibum quality were aggravated after 1 and 3 months of wearing an RGP lens (all p < 0.001). MGD grade, lid margin abnormality, meibomian gland expressibility, and meibum quality were significantly more aggravated in the RGP lens group than in the OK lens group after 3 months (p < 0.001, p < 0.001, p= 0.001, p < 0.001). CONCLUSIONS: Use of OK and RGP lenses affects ocular surface status. Especially, meibomian gland parameters and OSDI showed greater changes in RGP lens wearers than OK lens wearers.

PURPOSE: The purpose of this study was to investigate factors that influence married female immigrants' perceived health status. METHODS: This study was a retrospective review of dataset from the 2012 National Multicultural Family Survey in Korea. Data were analyzed using descriptive statistics, t-tests, an analysis of variance (ANOVA), Pearson correlation analysis, and multiple regression with the data of 3,014 married female immigrants. RESULTS: Multiple regression analysis showed that demographic factors (age, education level, nationality, period of residency in Korea, and residential area), socio-economical factors (monthly family income, employment, support from the government for basic living, and Medicaid), social support factors (marital conflict, satisfaction with family relationships, some one to talk about self or family matters, meeting with homeland friend, and participation in community meeting), and immigration factors (life satisfaction, experience of social discrimination, and difficulties with living and using medical care) were associated with perceived health status. CONCLUSION: It is important to pay closer attention to immigrant women who have low economic status, less social support, experience difficulties with living in Korea and using medical care. An effective support system for this population should be developed in order to help them successfully transition.

BACKGROUND: Controversy exists as to whether or not inhalation anesthetics and intravenous anesthetics impair arterial oxygenation (PaO2) during one lung ventilation (OLV). Accordingly, we examined the effect of enflurane and propofol on PaO2 and pulmonary vascular resistance (PVR) during OLV. METHODS: Forty patients, who had prolonged periods of OLV anesthesia with minimal trauma to the nonventilated lung were studied in a cross over design. Patients were randomized to four groups; Group 1 received 1 MAC of enflurane and oxygen from induction until the first 20 min after complete lung collapse, then were switched to propofol 100 g/kg/min (P100). In group 2, the order of the anesthetics was reversed. Group 3, Group 4 received the same order of the anesthetics as Group 1, Group 2, respectively but received propofol 200 g/kg/min (P200). RESULTS: During OLV, the PaO2 values were lower than those with two lung ventilation (TLV), there were no significant differences among each groups and between propofol and enflurane in PaO2, but in the selected patients (n=10, PaO2<120 mmHg during OLV), PaO2 in propofol group was higher than that of enflurane group (p<0.05). Conversion from TLV to OLV caused a significant increase in PVR, but there were no difference in PVR between propofol and enflurane group. CONCLUSIONS: These results suggest that the usual clinical dose of propofol affords no advantage over 1 MAC of enflurane anesthesia except low PaO2 patients during OLV. Propofol might be of value in risk patients of hypoxemia during thoracic surgery when OLV is planned.

BACKGROUND: This study aimed at identifying the effects of improved methods of endotracheal suction and hand washing on incidence of nosocomial pneumonia (NP) in the neurosurgical ICU. METHOD: Repeated training of nurses about hand washing and adherence of the single use of suction catheter and sterile normal saline of endotracheal suction was provided. Then hand washing compliance of nurses before and after training was investigated. and the incidence of NP in all patients hospitalized for more than 72 hours in the neurosurgical ICU was investigated from Sep 1, 2000 to Jan 31, 2001 (2nd surveillance). The NP rate of that period was compared with the incidence of the 1st surveillance period, from Sep 1, 1999 to Jan 31, 2000. The data were analyzed with chi-square-test. Fisher's exact test and logistic regression analysis by SAS 8.0. RESULT: The proportion of hand washing performance increased from 15.6% to 46.8%. The rates of NP per patient during 1st surveillance and 2nd surveillance were 10.3%, 3.9%(p=0.01) patient-days rates of NP were 10.0 cases/1,000 patient days, 4.1 cases/1,000 patient days(p=0.04), and ventilator-days rates of NP were 67.6 cases/1.000 ventilator days, 16.2 cases/1,000 ventilator days(p=0.00) respectively. Out of 29 isolates, 18 were methicillin-resistant Staphylococcus aureus, which was the most frequently isolated microorganism. The risk factors associated with incidence of NP were age, length of stay, Glasgow coma scale, diabetes mellitus, duration of intubation, insertion of endotracheal tube, duration of tracheostomy, presence of tracheostomy, duration of ventilator, use of ventilator, and insertion of nasogastric tube. CONCLUSION: These results showed that single use of suction catheters and sterile normal saline and increased compliance of hand washing were important factors to decrease the incidence of NP.

OBJECTIVE: In order to confirm the local production of total and specific IgE antibodies in the nasal polyp tissues. MATERIAL AND METHOD: We measured total IgE and house dust mite(Dermatophagoides pteronpssinus .' DP)-specific IgE antibody using enzyme-linked immunosorbent assay(ELISA) in the supernatant of nasal polyp homogenates from 72 subjects undergoing nasal polypectomy. The subjects were divided into three groups according to skin reactivity to DP: 20 strongly atopic subjects to group I(mean wheal diameter) 3mm), 19 weakly atopic subjects to group II (mean wheal diameter 1-3mm) and 33 negative skin responders to group III. RESULT: Group I showed significantly higher levels of total and DP-specific IgE levels in the nasa
