OBJECTIVES: To investigate the factors associated with symptoms from job stress among Korean dental laboratory technicians. METHODS: We collected the data of 786 technicians for life-style, job stressor, social support, self-esteem, personality, and various dimension of stress symptoms included roomatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, and hostility by self-administerd questionnaire. Global severity index of dental technician (GSID) was calculated by total sum of sub-dimension. RESULTS: We used 80 percentile as a cut-off point, and got the 81.5 % of sensitivity, 86.1 % of specificity by receiver operating characteristic curve. The odds ratios of various factors in high group of GSID compared with low group were 1,49(95 % Cl 1.00-2.00) for smoker, 1,53 (1.06-2.21) for unhealthy group, 6,69 (4.74-9.44) for work overload, 8.34(5.82-11.97) for work demand, 9.89 (6.76-74.94) for work process, 8.27 (5.80-11,79) for work environment, 5.82 (4.04-8.39) for interpersonal relationship, 8.34 (5.82-11.97) for occupational conflict, 5.70 (4.04-8.04) for labor remuneration, 7.58 (5.37-10.71) for role conflict, but 0.39 (0.27-0.57) for social support, 0.41 (0.29-0.60) for self-esteem. By multiple logistic regression, factors were significantly associated with GSID were age, working area, role overload, work demand, work procedure, physical environment, occupational conflict, role conflict, social support, personality traits. CONCLUSIONS: Factors associated with symptoms from stress were role overload, work demand, work procedure, occupational conflict, interpersonal relationship, labor remuneration and role conflict in Korean dental laboratory technicians. It is suggested that health promotion program to reduce job stress and to enforce social support and self-esteem should be developed.

Rhabdomyosarcoma are reportedly the most common soft tissue sarcoma occuring in childhood, but the biliary tree is a rare site of origin for this tumor. Recently we experienced a case of embryonal rhabdomyosarcoma of the biliary tree in a 30-month-old child. UItrasonography showed hypoechoic mass filling the dilated left. intrahepatic & extrahepatic bile ducts, and CT showed hypodense mass with heterogeneous enhancement after contrast infusion. Intraoperative cholangiography showed filling defects within the dilated left. intrahepatic & extrahepatic bile ducts. Postoperative MRI showed residual mass within the left. intrahepatic duct which was hypointense on T1WI and hyperintense on T2WI.

Studies on epidemiological aspects of contact dermatitis have been published in recent years since the introduction of standardized method of patch test.However, most previous epidemiologic reports studied patients with allergic contact dermatitis in hospitals with patcb testing. Such data are not directly applicable to the population at large. Very recentiy there are a few reports ahout rates of exposure and patch test reactivity to certain antigens in a general population. which is difficult to be applicable in a developing country at present. With regard to this, we have tried to analyze the contact dermatitis questionaire containing various items of common causative agents producting contact dermatitis (for example, metals, cosmetics, plants, medicaments and rubber etc.) for the detection of past contact dermatitis histories in a total new dermatologic outpatients. A11 2258 dermatologic outpatients entered this study including 303 contact dermatitis patients (allergic contact dermatitis, primary irritant dermatitis and housewife eczema). We also analyzed the patch test results of 107 patients with suggesting contact dermatitis who visited our hospital at the same period of collecting questionaires. The study results were as follows. 1. Positive rate of each item of the questionaire (No. of said Yes/ No. of responders) was metals, 10.4% cosmetics, 31.8%, plants, 18.2%; medicaments, 12.4%; rubber, 5.8%; and others, 11.7%. 2. The most common all regens of the patch test positive reactions were nickel sulfate (9.3%), fragrance mix(9.3%), formaldehyde(6.5%), potassium dichromate (5.6%), neomycin sulfate (5.6%), balsam of Peru (4.7%), cobalt chloride(3.7%), wood tar(3.7%) and paraphenylene diamine (2.8%) in order of frequency. And the patch test positive rate of commercial cosmetic products was 10.3%. In conclusion, cosmetics, medicaments, metals, plants and rarely rubber are found the most common etiologic agents of contact dermatitis in this study. The reasons and back-ground of the results were also discussed in various aspects.

Perforating calcific elastosis, referred to as periumbilical perforating pseudoxanthoma elasticum that can occur in middle-aged, multiparous, obese women with a possible genetic predisposition to pseudoxanthoma elasticum. We report two cases which showed the clinical and histopathologic fundings of perforating calcific elastosis in a 77 year-old and; 69 year-old woman. Clinically, the losio is were well-demarcated, yellow to brownish hyperpigmentcd and verrucous plaques with discreted ratotic papules just above the umbilicus. Histopathologically, altered basophilic calcified elastic fiber were extruded through the hyperplastic epidermis to the surface of the skin and were present in the eticular dermis.

BACKGROUND: Evening primrose oil(EPO) is a rich source of cis-linoleic acid and gammalinolenic acid(GLA) and has been used as a therapeutic agent in various skin diseases such as atopic dermatitis. OBJECTIVE: The purpose of this study was to evaluate the suppressive effect of EPO on murine contact sensitivity. METHODS: BALB/c mice were divided into 3 groups, positive control, experimental and negative control groups: the positive control group represents a group of mice which were sensitized and challenged with DNFB, the experimental group represents EPO-pretreated positive control group and the negative control group represents a group of mice which were challenged only. The changes of ear thickness were measured, and H & E staining and immunohistochemical staining for ICAM-1 expression of ear skin were performed to evaluate the histological changes of each group. RESULTS: The Pretreatment of mice with EPO resulted in suppression of contact sensitivity by more than 82%. On H & E staining, only a mild inflammatory reaction was observed in the dermis. Also ICAM-1 expression of keratinocytes, the intensity of the staining was significantly decreased in the experimental group compared with positive group. CONCLUSIONS: Our study indicates that EPO was able to suppress the induction of contact sensitivity.

The photostress test was applled in 80 normal eyes and in 30 eyes with macular lesions. The normal recovery time ranged from 5.3 seconds to 12.6 seconds, its mean was 7.89 seconds. In patients with macular lesions the test results showed wide scattering of values, ranging from 8.0 to 255.0 seconds and the mean value being 57.01 seconds. These two mean values showed highly significant difference. It can be concluded that the photostress test is valuable for making diagnosis and for evaluating the present status of the lesions and their prognosis in macular lesions.

BACKGROUND: Data on the frequency of Herpes Zoster are sparse, especially in inpatients OBJECTIVE: The purpose of this study was to elucidate the epidemilogy and the clinical characteristics of herpes zoster in inpatients. METHODS: During a 3-year-Period from Jan. 1991 to Dec. 1991, 157patients with herpes zoster were evaluated in regard to annual, monthly and seasonal incidence age incidenee and sex ratio. Patients with herpes zoster were further assessed concerning associratel conditions, dermatomic distributions and complications. RESULTS: 1. The annual rate ranged from 2.6% to 3.3% (mean 2.8%) and the ratio of male to female was 0.85: 1. 2. There were no marked manthly of spasonal differences in herpsoster, ranging from 4.5% to 10.8% and 21.7% to 31.2%, respectively. 3. Herpes Zoster was seen most frequently in the 50-59 year age group(27.4%) 4. The dermatomic involvernent of herpes zoster was most freqer t of thoracic dermatome(51.6%) and others were trigeminal(19.1%), cervical(13.4%), lumbar(6.4%), sacral(5.7%), facial(1.9%) and generalized(1.9%). 5. The frequency of associated conditions in herpes zoster was in d scending order, hypertension, tuberculosis, diabetes mellitus, malignancy, SLE, gastric ulcer, chronic renal failiure, rheumatoid arthritis, idiopathic pulmonary fibrosis. 6. The most common complication of herpes zoster was postheret c neuralgia and others were ophathalmologic complications, secondary bacterial infection, keloicl, formation, generalized varicelliform eruption, recurrent herpes zoster. CONCLUSION: Herpes Zoster is a major problem in the Department of Dermatology, especially in inpatients.
