To measure the serum succinyl trialanine p-nitroanilide hydrolytic activity as new index of liver function in workers exposed to organic solvents, this study conducted 114 workers in department of shoe-making of shoes factories. The results obtained from this study were as follows: 1. The mean values of serum GOT, GPT, gamma GT in whole workers were 22+/-12.32, 20+/-9.65, 28+/-21.35IU/l, respectively and the mean value of serum STN hydrolytic activity was 0.08 0.05. 2. The serum STN hydrolytic activity was significantly higher for male(p<0.05) and there was no difference among the groups of age. 3. There was no difference in the groups by working hours but significant difference in persons who worked over 3 years or were exposed to toluene over 100ppm(p<0.05). 4. The correlation of the exposed dose of toluene and serum GOT, GPT, gamma GT and serum STN hydrolytic activity were statistically significant(r=0.027-0.518). 5. The exposed dose of toluene was most explainable variable and statistically significant among the factors affecting serum STN hydrolytic activity(p<0.05).

Familial lichen planus is an uncommon disease, and there are 104 cases reported in the English literature. Several theories regarding the etiopathogenesis of lichen planus have been proposed. However, immunological mechanisms and genetic susceptibility have been emphasized the most. Several reports showed HLA analysis in lichen planus patients, and recently 2 cases have revealed an increased frequency of DR1 antigen in patients with lichen planus compared to a control group. We observed two brothers with typical skin lesions of lichen planus of almost simultaneous onset. We confirmed lichen planus by skin biopsies in both brothers and analyzed HLA typing. We also observed the occurrence of DR1 antigen in both of them.

A umbilical omphalomesenteric duct polyp is the result of incomplete closure of the omphalomesenteric duct, which connects the midgut with the yolk sac of the embryo. It may be associated with underlying embryologic anomalies such as Meckels diverticulum and umbilical enteric fistula, the complications of which may at times be fatal. This rare malformation should be clinically discerned from persistent granulation tissue or pyogenic granuloma. Histologically, it shows a polypoid lesion consisting of ectopic gastrointestinal epithelium with the appearance of gastric, intestinal, or colonic mucosa. We report a case of an umbilical omphalomesenteric duct polyp in an 8-year-old male patient, who had had a bright-red polyp on the umbilicus from the age of 1 month and had not had any other types of underlying abnormalities.

Angiokeratoma circumscriptum is present at birth or early childhood and is an uncommon dermatosis characterized by papules and small nodules that may coalesce to form plaques. Histopathologically, there are varying degrees of hyperkeratosis, papillomatosis, and irregular acanthosis. In the papillary dermis, greatly dilated capillaries are observed, The acanthotic epidermis encircles the vascular spaces(blood cysts) where, occasionally, organized thrombi may be found. The use of pulsed-dye lasers to treat cutaneous vascular lesions is based on the theory of selective photothermolysis. We report a case of an angiokeratoma circumscriptum in an 48-year-old woman for whom the flashlamp pulsed tunable dye laser proved to be a highly successful means of treatment.

Though people occupationally exposed to machineries and automation in the industrialized society desire work involving decreased strength, due to the continuous and repetitive activities, a new industrial stress is present. Studies on prevalence of musculoskeletal disease and their related risk factors have evolved. In this study in relation to work tasks, we investigated the differences in musculoskeletal symptoms occurring in each body region. The results of the survey were as follows. 1. When comparing age, level of education, work duration, job satisfaction and leisure time activities according to work risk, age in control group was 32.83+/-5.5, in comparison to the other 2 groups was smaller(p<0.05), and level of education in control group was higher(p<0.05) Work duration in the cutting department as 8.04+/-4.99 years longer than the other 2 groups(p<0.05), but there was no difference in the job satisfaction and leisure time activities. 2. The mean of symptom scores of each work task was 1.54 in the cutting department, 1.57 in the press department and 1.59 in the control group, and there was no significant difference in the 3 groups. The mean of symptom scores for upper extremities in the control group was low but mo statistically significant difference was shown. 3. When comparing the mean of symptom score according to work task in the each body region, in the shoulder region, the symptom score in the press department which desired strength was higher than the other 2 groups but no significant difference was shown. In the wrist region the cutting department scored 1.01 and in comparison to the other 2 groups was significantly increased(p<0.05). 4. The results of the univariate regression analysis on the major individual risk factors associated with musculoskeletal symptom relating work showed that previous symptom complaints in the same body region was significant risk factor(p<0.001) in the whole body, Besides wrist, hip, and knee, psychological problem was shown to be a significant factor(p<0.05). And the body regions which work task was significant risk factor were wrist and neck region(p<0.05). 5. The results of the multiple regression analysis involving significant factors of each body region from the unfavorite regression analysis showed that previous symptom shoulder, elbow and lumbar region(p<0.001) and psychological problem in the shoulder, elbow and lumbar region(p<0.05) were significant factors, and work task was significant factor in the wrist(p<0.05).

The aquatic quality of the Naktong river after two of three months in June, 1991 with phenol spillage from a electrical factory in Kumi was investigated. The samples were collected at six sites of the Naktong river basin and Kachang and Kongsan lakes. Phenol was not detected from all water samples. Turbidity was very much increased to the down stream in the Naktong river. The BOD and COD values exceeded the 2nd grade(3 mg/l) of the Korean standard quality of Environmental Water Act at the all sampling sites of the Naktong river. Especially, the value of COD at Kaejin (12.5 mg/l) was poorly classified as to the 5th grade of water class for the environmental quality standards. Organophosphorous pesticides such as parathion, malathion, fenitrothion and diazinon were investigated but not detected. Diazinon was only detected at the Ilson bridge(1.42 ppb), Okkye stream(6.95 ppb), Waekwan bridge(0.32 ppb), Gangjung reservior(0.13 ppb), Kaejin(0.05 ppb). Of the carbamates such as carbanyl, isoprocarb and cabofuran, the carbofuran was detected all sites except tap water, and Kachang and Kongsan lakes. The content of heavy metals such ans Cd, Pb, Zn, Fe, Mn, Hg were not exceeding for drinking water standards at the all sampling region, but only mecury was detected from Okkye stream(0.018ppb) and Kaejin(0.09ppb). In the regions of Kachang and Kongsan lakes, the content of heavy metals were lower than that of reservoir of Naktong river.

PURPOSE: We studied this study to see the effect of hearing music on response to pain during needling. We hypothesized that music would reduce pain in newborns. METHODS: Twenty term and near-term newborns were enrolled for the study. They were admitted to neonatal intensive care unit of Hanyang University Guri Hospital from May 1, 2011 to September 30, 2011. We evaluated pain response to needling, such as arterial puncture or heel prick, by using Neonatal Infant Pain Scale (NIPS; facial expression, crying, breathing patterns, arms, legs, state of arousal) and duration of crying through video recording. We started video recording when the newborns were stable with 0 score of NIPS, and continued for 3 minutes after needling. Each newborn took video-recordings in 2 separate periods. One was done with hearing music (Music group) and the other without music (Control group). Two observers reviewed the videotapes and gave final scores in agreement. T-test was done for comparisons of pain scale and duration of crying between music and control groups. RESULTS: Mean age and hospital days at test of the subjects were 6+/-5 days of life (1-16 days of life) and 3+/-2 days, respectively. Twenty-one of 40 needlings (52.5%) for blood sample were from radial arterial puncture and 19 (47.5%) from heel prick. The music group had lower NIPS score than the controls (5.6+/-1.1 vs 6.5+/-0.7, P=0.006). Among the NIPS parameters, the music group had lower scores in crying and arm (crying, 1.6+/-0.5 vs 1.9+/-0.3, P=0.028; arm, 0.3+/-0.5 vs 0.7+/-0.5, P=0.01) parameters. The remaining parameters such as facial expression, leg, breathing patterns and state of arousal, and duration of crying were not significantly different in 2 groups. CONCLUSION: c reduced pain response to needling in newborns. Music could be one of modalities to relieve pain during routine medical procedures in newborns.

PURPOSE: To assess clinical features and efficacy of spectacles and low vision devices in pediatric patients with albinism. METHODS: A retrospective study was performed of 15 pediatric patients with albinism for whom glasses and low vision devices had been prescribed to determine subjective satisfaction and objective improvement in visual acuity (VA), strabismus, contrast sensitivity, number of reading letters during 1 minute with refractive correction and low vision devices. RESULTS: The median refractive correction was +0.12 +/- 5.45 diopter (D) spherical equivalent with -0.71 +/- 3.62 D astigmatism. Most patients complained of reading difficulty and photophobia. Hand-held magnifier and Keplerian telescope were commonly prescribed low vision devices. In addition, VA, strabismic deviation, contrast sensitivity and number of reading letters during 1 minute significantly improved after wearing glasses and low vision devices. CONCLUSIONS: The present study showed a significant improvement in corrected VA, alignment and subjective symptoms in pediatric patients with albinism by wearing glasses and low vision devices. Additionally, high compliance can improve final patients' satisfaction through using training of low vision devices.

Cutaneous horn is a nonspecific clinical description and may arise from a variety of benign and malignant lesions. A 46-year-old Korean man presented with a 1-year history of an extensively hyperkeratotic nodule on his left foot. Following an initial diagnosis of dermatofibroma with underlying cutaneous horn by wedge biopsy, the tumor was completely removed by excision with 5 mm margin. When excisional surgery was performed, the size of the dermal tumor mass was found to be 1.3 cm in length on the axis and 0.6 cm in depth on section. On histopathologic examination, the tumor was characterized by spindle-shaped cells arranged in storiform pattern, epidermal hyperplasia, and an overlying compact hyperkeratotic mass. The tumor cells did not express CD34. Cutaneous horn of dermatofibroma may be the product of epidermis-dermal tumor interaction. Although we performed a wide excision for complete removal of the tumor, Mohs micrographic surgery could have been another option.

Dariers disease is inherited as an autosomal dominant trait and characterized by follicular pruritic hyperkeratotic papules. The onset is usually in late childhood and the course of the disease is chronic and slowly progressive in most cases. Dariers disease is refractory to treatment with most conventional keratolytics and anti-inflammatory agents. To date, oral and topical retinoid products have been the mainstay therapy for this population, but local as well as systemic side effects often limit their effectiveness. We present a case of localized Dariers disease which responded promptly to the topical application of adapalene 0.1% gel without side effects. A review of treatment for Dariers disease also is presented.
