Glutaraldehyde is commonly used as a biocide to disinfect delicate instruments such as dental instruments, to treat warts, hyperhidrosis and bullous diseases and as a preservative in various materials. Contact sensitivity to glutaraldehyde may not be detected, because it is not included in the standard screening chemicals recommended in the screening tests. We report a case of allergic contact dermatitis caused by Wydex(2% glutaraldehyde). A 54-year-old female made a visit to our departrnent with eczematous dermatitis of both hands, neck and face. She worked as a cleaner in delivery room and newborn nursery, and had developed the dermatitis 1 month after Wydex' containing 2% glutaraldehyde had been to clean the rooms. She had no family or personal history of atopy or contact dermatitis. Patch tests with Korean Standard(KS-1000) and Wydex were performed, and patch tests with 2% glutaraldehyde, 0.2% gluteraldehyde and rubber mix followed. The positive results were, Wydex 2% ++, 0.2% +, 0.02% + and. glutaraldehyde 2% aq. +, 0.2% aq. + on day 2 and day 4. We confirmed that the skin lesions had been caused by Wydex . The symptoms were eradicated after she changed her work environment and there has been no evidence of recurrence.

PURPOSE: This study was done to identify the influence of workplace violence on anger and post traumatic stress disorder among nurses. METHODS: The research design for this study was a descriptive survey design using a random sampling. Data collection was done using self-questionnaire with 477 nurses. The collected data were analyzed by descriptive statistics, chi2-test and logistics regression. RESULTS: The incidences of total violence, verbal, physical, and sexual violence were 31.2%, 28.7%, 6.3%, 3.6% of the nurses, respectively. Anger was significantly associated with verbal violence (OR: 2.34, CI: 1.40~3.91) and physical violence (OR:4.85 CI: 1.67~14.13). Post traumatic stress disorder was significantly associated with verbal violence (OR: 15.99, CI: 9.58~26.69) and physical violence (OR: 5.37, CI: 1.66~17.40). CONCLUSION: To promote psychological health in nurses, there is a need to develop prevention programs to decrease workplace violence and to develop programs supporting psychological aspects of verbal violence that nurses experience.

Facial asymmetry is the most frequent disease in craniofacial deformities. And the primary causing area of that is mostly placing in mandible. That is to say, it is known that primarily, mandible grows excessively or deficiently, and other facial region involving maxilla undergoes compensatory growth secondarily, so asymmetric face develops. In facial asymmetry, the surgical correction of undergrowth is more difficult than that of overgrowth and the reason of it is the postoperative relapse caused by stress of surrounding soft tissues. It means the stress of surrounding soft tissues occurring after bone lengthening and reducing above stress is the same meaning with reducing postoperative relapse. Among various areas, mandibular ramus is the most difficult area to lengthen vertically and maintain its length. The reason of it is considered by many authors as the stress of surrounding pterygomasseteric sling which is enveloping lower border of mandible and interrupting elongation of ramal height. So we applied two different surgical procedures in which pterygomasseteric slings have different stress respectively to monkeys which have similar masticatory function and anatomy to human being and compared relapse by radiographic film and observed periodically the histochemical change of masseteric muscle fiber. So we could see the following results. The relapse was less in EVRO group in which we separated pterygomasseric sling in inferior border and didn't approximate muscle sling after vertical lengthening to minimize the stress of soft tissues than IVRO group in which we elongated ramal height preserving pterygomassetric sling. Of course, we could see a problem in EVRO group such as bone resorption in inferior border caused by uncovering the periosteum of inferior border. But we expect that such problem will be solved by developing periosteum substitutes for covering the exposed bone and minimizing the surgical trauma. In histochemical study of masseteric muscle fiber, the fiber constituents of EVRO group in which we minimized soft tissue stress was changed immediately after operation and maintained it for 1 year, whereas that of IVRO group in which we preserved soft tissue stress was changed in more portion after operation and recovered it by 1 year . By the histochemical results, we can see that the recovery of fiber constituents reflect the recovery of muscle stress and it is closely related with relapse phenomenon.

We report two cases of type V hyperlipoproteinemia and eruptive xanthomas associated with diabetes mellitus in a 44-year-old woman and a 25-year-old woman. They had asymptomatic, diffuse, erythematous yellowish papules on the extremities and buttocks. The laboratory studies showed increased serum blood glucose, total cholesterol, triglyceride, increasing pre-β and chylomicron bands on electrophoresis of lipoprotein. Histopathologic findings of erythematous yellowish papules on the thigh and buttock revealed aggregation of foam cells in the dermis. They have been treated with diet control, hypoglycemic agent (gliclazide) and hypolipidemic drug (gemfibrozil), and are under continued supervision.
