Occupational dermatosis is one of the most prevalent occupational disorders. However, the extent of the occupational dermatoses including incidences and prevalencies of each disease entity, and etiologic materials are not yet well stated in Korea. Authors reviewed the literatures on the statistic data and reports on the occupational dermatoses, and surveyed on the occupational dermatoses in two factories, and surveyed the physicians responsible to the occupational dermatoses with formed questionnaire. The results are as follows; 1. Among medical journals published since 1964, there were 31 articles on the occupational dermatoses. Of 31 articles, 18 were case reports and all others were review articles. Of 18 case reports, 9 were epidemiologic survey. The Workers' Periodic Health Examinations revealed that prevalence of the occupational dermatoses was highest(4.36 per 10,000 workers) in 1974, but number of the cases reported were decreased sharply since 1978 with some tendency to increase since 1987. There were 2,240 reported cases of occupational dermatoses between 1966 and 1992, which is 1.90% of all the reported occupational diseases. Skin infection and injuries due to chemicals were most frequent and there were 6 cases of skin cancer. 2. In an epidemiological survey on the dermatoses among 995 workers in a metal product manufacturing factory and 225 workers with acne, 130 workers with scar, 123 workers with deformity of toe nails. Scars, photosensitivity dermatitis, deformity of finger and toe nails, and acne were more prevalent in the metal product manufacturing factory(p<0.05). In the metal product manufacturing factory, workers treating organic solvents and oils had more dermatoses than those without treating the materials(p<0.05). On the skin patch performed on 16 workers in the metal product manufacturing factory, there were 8 cases of irritation dermatitis and 5 cases of contact dermatitis. Prevalence of contact dermatitis in the metal product manufacturing factory was 1.3%. 3. On the questionnaire survey, 34 dermatologists, 29 doctors of preventive medicine, and 22 family physician replied. The proportion of occupational etiology among all dermatoses assumed by the physicians were below 9%, and the most important occupational dermatosis in Korea was contact dermatitis. Main etiologic materials related to the occupational dermatosis were organic solvent, acid and alkali, and metals. The reason for the scarcity of report of occupational dermatoses were difficulty in diagnosis and physician's ignorance of the occupational etiology. They replied that to prevent the occupational dermatosis in the workplace, the use of protective devices was most important, and development of diagnostic criteria on the occupational dermatoses is urgent. Above results shows us that there is many workers with occupational dermatoses, but they are mostly unreported. Measures to prevent and manage the occupational dermatoses are not satisfactory at present. Hence, authors suggest measures for the precises diagnosis, report and prevention of the occupational dermatoses. a. Dernatikigustm orevebtuve physician, and industrial hygienist should work as a team to examine the high risk group and establish the preventive measures. b. Disease entities, diagnostic criteria of occupational dermatoses should be listed, criteria for the compensation and job fitting at recruitment should be established, and manual for the proper treatment and effective prevention of each occupational dermatosis should be developed. c. Patch test antigens against each occupational category should be developed and it should be available to any physicians responsible. d. To facilitate the diagnosis of occupational dermatoses by the doctors responsible for the Workers' Periodic Health Examination, development of standardized questionnaire, education on the techniques of the patch test, and cooperation with the dermatologist in diagnosis of occupational dermatoses is essential.

OBJECTIVE: Macrosomia is associated with increased birth injury and neonatal morbidity as well as a higher rate of cesarean delivery. Our purpose was to determine whether induction of labor after sonographic diagnosis of fetal macrosomia could improve maternal and neonatal outcome. STUDY DESIGN: The hospital records of 180 patients who delivered of an inFant with birth weight over 4000 gm were reviewed. The subjects were divided into three groups based on obstetric management as follows.. expectant management after sonographic diagnosis of fetal macrosomia(group I), induction of labor(group lI), unexpected patients who were underestimated of fetal weight(estimated fetal weight<90th percentile) (groupIII), Patients who underwent elective cesarean delivery and complicated with diabetes were excluded. Outcome variables for comparison in three groups were mode of delivery, 5 minute Apgar score below 7, presence of cephalohematoma, clavicular fracture, brachial plexus injury, and intraventricular hemorrhage. RESULTS: One hundred eighty patients who eligible for the study, of whom 32 patients were included to group I, 57 patients to group lI, and 91 patients to group Ill, respectively. The cesarean rate within elective induction group was 49%, which was significant higher than the 16% rate in expectant management group and 19% in unexpected group(p<0.05). The observed rates of cephalohematoma, clavicular fracture and 5 min Apgar score below 7 were not significantly different in three groups. CONCLUSIONS: There was an significant increased cesarean delivery rate without improvement in neonatal outcomes or reduction in birth injury among pregnancies in which labor was electively induced after sonographic diagnosis of fetal macrosomia. Elective induction of labor should be discharged in cases with fetal macrosomia.

Since coronary arteriovenous fistula(CAVF) was first reported by Krause in 1865, more than 400 cases have been reported. It is relatively rare disease and originates more commonly in the right than in the left coronary artery. We report a case of CAVF between right coronary artery and right ventricular inflow tract with significant left to right shunt in a 34-year old female who was admitted for the cardiomegaly on routine chest X-Ray. It was detected by transthoracic and transesophageal echocardiography, and confirmed by cardiac catheterization and coronary angiography. The opening of the fistula draining into the right ventricle was obliterated with sutures. There was no significant shunt in postoperative cardiac catheterization and coronary angiography.

BACKGROUND: Mesenchymal stem cells can be expanded rapidly in vitro and differentiated into multiple mesodermal cell types. This study was planned to isolate human adipose tissue stromal cells (hATSCs) from human liposuction tissues and to investigate the changes of tactile threshold after hATSC transplantation in animal neuropathic pain models. METHODS: hATSCs were grown under control conditions in alpha-MEM/10% FBS. To prepare neuropathic pain model rats, thirty male Sprague-Dawley rats that had the average body weight of 208 +/- 5 g, had an experimental nerve injury by cutting or clamping of sural and tibial nerves. The tactile threshold was measured by von Frey hair filament at preinjury and postoperative day (POD) 1, 2, 3, 7, 14. Transplantation of hATSCs was performed after measurement of tactile threshold at POD3. RESULTS: hATSCs grew as a monolayer of large, flat, and spindle-shaped cells. The tactile threshold after spared nerve injury was significantly decreased since one day after cutting or clamping of nerves (P < 0.01). The percent changes of a tactile threshold in clamping and hATSC group were decreased to 59.8 +/- 7.1% (POD7) and 52.6 +/- 5.1% (POD14) (P < 0.05). CONCLUSIONS: This results was suggested that hATSCs could be isolated from human adipose tissue easily. Althogh it needs more long-term investigation hATSCs might be used as a method of therapy for neuropathic pain.

Adenolipoma of the thyroid gland, also called thyrolipoma, is an extremely rare neoplasm characterized by encapsulated or tumorous mass of admixtures of mature adipose tissue and thyroid tissue. Only a few scattered cases have been reported in English literatures. It should be differentiated with encapsulated papillary carcinoma, follicular neoplasm and liposarcoma. We report an additional case of an adenolipoma of the thyroid gland.

OBJECTIVE: To analyse neonatal outcomes of the very low birthweight infants born to women who underwent an indicated preterm delivery and spontaneous preterm delivery. METHODS: We performed an observational study of 150 very low birthweight(<1500 grams) infants delivered at Samsung Medical Center. The study population was limited to singleton infants without major congenital anomalies. The primary reason for delivery was categorized as indicated preterm delivery or spontaneous preterm delivery. Selected neonatal outcomes were compared between infants born to women in each of these groups. RESULTS: Univariate analyses showed some survival benefits in infants born to women who underwent indicated preterm delivery. Selected neonatal outcomes, however, did not differ between the groups in the multiple logistic regression analysis. CONCLUSION: There was no survival advantage to the very low birthweight infants born to women who underwent an indicated preterm delivery compared to those born to women with spontaneous preterm delivery.

OBJECTIVE: The aim of this study was to determine whether fetuses delivered prematurely because of pregnancy complications had a different neonatal outcomes than that of those bom after either spontaneous preterm labor or after premature rupture of membrane. METHODS: The study design was a retrospective analysis of 150 very low birthweight(<1500 grams) infants and their mothers who delivered preterm neonates at Samsung Medical Center. Only singleton infants without major congenital anomalies were included. The primary reason for delivery was categorized as preterm delivery because of pregnancy complications(indicated preterm delivery) or spontaneous preterm delivery. Selected neonatal outcomes were compared between infants born to women in each of these groups. RESULTS: There were some survival benefits in infants born to women who underwent indicated preterm delivery from univariate analyses. In the multiple logistic regression analysis, however, selected neonatal outcomes did not differ between the groups. CONCLUSION: We concluded that a "stressed" pregnancies confer negligible survival advantage to the very low birthweight infants.
