Hand dermatitis of silk industry workers had been a troublesome problern for a long time. It was said the cause was due to toxic reaction by denatured pupae and physical reaction from high water temperaturc. During Augnst and September 1973, patch test was performed with pupa and cocoon to 680 workers in 4 separate silk factories in order to persue the factors which may cause their hand dermatitis. Among 475 workers who had performed first patch test, only 12 workers in one of four factories showed positive reaction in pupa and we came to know that only that factory had used formalin in order to protect denaturation of pupae and cocoons. Second patch test with pupa and 1% formalin was repeated to 130 subjects including 6 of 12 positive cases in the first pateh test. Five Subjects shosved positive reaction in pupa, also 5 in 1% formalin and 2 of them showed positive reaction in both pupa and 1% formalin. In the second patch test, 3 of 6 who had been positive in pupa at first patch test were positive at pupa. It seemed to be that toxic or allergic theory is not enough to explain clearly the cause of hand dermatitis in silk industry workers. Further stucly is necessarv to elucidate how the silk fiber, water temperature and parasites in the pupa and cocoon contribute to the hand dermmatitis.

PURPOSE: To evaluate the indication for intracavitary Urokinase(UK) in the treatment of Ioculated pleural effusion. MATERIALS AND METHODS: We analyzed CT and US in 31 patients who were treated with intracavitary UK in Ioculated pleural effusion. In each patient, a single chest catheter (10-12F) was insected under imaging guidance. When the amount of drainage was less than 100ml/day, UK was instilled through the catheter until less than 50ml/day was drained. On follow-up chest radiographs of more than 1 month, we classified the results of treatment into 3 groups:(1) completely effective (lung expansion, over 80%);(2) partially effective (20-80%); (3) ineffective (below 20%) group. Sonographic pattern of pleural fluid was classified into anechoic, septated, and honeycomb appearances and the thickness of parietal pleura was measured on CT. RESULTS: Sixteen patients were completely effective, nine were partially effective, and six were ineffective. patients with completely or partially effective outcome had anechoic and linear septated appearance on had less than 4mm of parietal pleural thickness on CT. Of six ineffective patients, US showed linear septated in one patient and honeycomb appearance in five patients and the thickness of parietal pleura on CT was 3 mm in one patient, 4ram in two patients, 5mm in one patient, and 6mm in two patients. CONCLUSION: UK instillation through percutaneous catheter was an effective method in the treatment of Ioculated pleural effusion. However, we found near complete reaccumulation of pleural fluid when honeycomb appearance of pleural fluid on US or more than 5mm parietal pleural thickness on CT was observed, which might suggest that we should consider the other kinds of treatment method in those patients.

Microsporum gypseum, long considered to be of animal origin, has recently been found to be soil inhabitating fungus and abundant in soil throughout the world. M. Gypseum infections tend to increase nowadays in Korea. Nineteen cases of ringworm caused by M. gypseum were reported in Korean literature until 1980 to the best of our knowledge. We present 5 cases of M. gypseum infection confirmed by culture findings on Sabouraud agar media and microscopic examination. The first case was 4 year-old boy with solitary coin sinzed pruritic annular erythernatous plaque ontaining papules, pustules and scales on the right cheek of on month duration. The second case, 7 year-old boy, had solitary walnut sized ovoid plaque consisted with papulopustules, oozing and peripheral scaling on right cheek of one month duration. The third case, 5 year-old boy, had solitary egg sized pruritic erythematous plaque with papuIes, scales and crust on the right lower leg of three weeks duration. The fourth case, 63 year-old female, had solitary egg sized sharply demarcated erythematious scaly patch with central clearing on nose and. nasolabial area of 10 days duration. The last case was 2 year-old girl with solitary coin sized annular erythematous scaly pIaque on left lower leg of two weeks duration.

BACKGROUND: There are reviews with regard to the treatment of pigmented nevi present on the palms, soles, and genitalia. One advocated that pigmented nevi on thesa locations should be prophylactically removed to avoid their tuture development into malignant melanoma, while the other believes that this is not practicable. OBJECTIVE: Our purpose was to determine the incidence rates and clinical characteristics and to discuss the management of pigrnented nevi, developed on these areas of the Korean men. METHOD: We examined 1,537 Korean men, between 19 and 21 rears old, to evaluate the pigmented nevi on their palms, soles, and genitalia. RESULTS: Atleast 1 pigmented nevus appeared in 314(20.4%) men on the palms, 189(12.3%) on the soles, and 117(7.6%) on the genitalia. The sizes(mean diameter) of nevi on genitalia, soles, and palms were 4.5mm, 3.1mm, and 2.3mm respectively. The color of the nevi was darkest on the penile shaft(4.3 point) and then glans penis(3.9 points), soles(3.2 points), palms(2.5 points) in decreasing orders of the points. Most of the nevi was consistent with type 1 by Levers clinical classification and their incidence were 357 on palms, 211 on soles, and 128 on genitalia. Among the 21 nevi of type 2, 13 nevi appeared on the soles, and noine of type 3 and type 5 were found. The distribution of the nevi on the palms was of a rather uniform and scattered pattern, whereas, on the soles, they were distinctly concentrated in the midfoot. Tkie nevi on the glans penis appeared larger and more irregular in outline than those on the penile shaft. CONCLUSION: The plantar nevi were larger, darker, and had greater incidence of elevated type compared with the palmar nevi. From this observation, particular attenticn should be paid to the presence of pigmented nevi on the soles.

Impaired sweating reportedly has been associated with a high incidence of heat pyrexia. An important cause is attributed to sweat gland fatigue following intense prolonged sweating. For further investigation, sweat gland fatigue was induced by heat exposure for 2 hours in a hot room (dry bulb 46c, wet bulb 37c) with 9 healthy subjects. Sweating rate of the right forearm increased progressively for the first 45 minutes with a maximum value of 40.0mg/4. 91 cm2/15 min followed by a slow decrease to 24.9 mg/4.91cm2/15 min at the end of 2 hours. Active sweat pores decreased in number following 2 hours of heat exposure but the differences were not significant statistically. In spite of the higher sweat rate on the back, the number of active sweat pores was smaller as compared to the right forearm. Na+ concentrations of the second hour sweat collections were higher than those of the first hour with difference of 14. 9 mEq/l on the right forearm and 12.3 mEq/1 on the back.

Serum IgE values were determined in 100 patients vith atogic dermatitis in the Department of Dermatology at Severance Hospital, Yonsei University College of Medicine, from Oct. 1, 1978 to Mar. 31, 1980. Mean IgE value of patients is 293. 4 unit/ml which is significantly higher than reference value, and the following results were obtained. 1. The mean IgE value in adults with atopic dermatitis, 339.8 unit/ml, 30 cases: more tian 16 years old) was significantly higher than in children(251. 4 unit /ml, 70 cases). 2. Male patierts showed higher IgE va,lue (mean 324. 5 unit/ml, 62 cases,' than female patients (242.7 unit/ml, 38 cases). 3. No close correlation was demonstrated between IgE values and eosiniphils in blood. 4. Patients with parasitic infesta,tion (5 cases) showed relatively increased IgE values (mean; 116. 2 unit/ml;. 5. Patients wifh bronchial asthma (2 cases) showed high IgE values exceeding 1000 unit/ml, 6. IgE. values roughly correlated with severity of the dermatitis. Four cases with high IgE values exceeding 1000 unit/ml were included in the clinically severe group.

The association rate of antibody with antigen has been reported to be greatly increased by lowering ionic strength. Low-ionic strength salt solution(LISS) method has been used for the detection of various alloantibodies. To investigate the sensitivity of LISS in indirect antiglobulin test, a comparison study of LISS with saline and albumin methods was conducted. A total of 32 patients' samples requested for indirect antiglobulin test were evaluated. Out of 32 patients with clinical immune hemolytic anemia, 11(34.3%) were positive in 37 degrees C saline antiglobulin test, 18(56.2%) in albumin antiglobulin test, 23(71.8%) in LISS antiglobulin test respectively. These results were statistically analyzed using non parametric Page's test for ordered alternatives. LISS method is more sensitive than 37 degrees C saline method or albumin method significantly (p<0.01).

While a giant cell tumor most frequently involves the distal end of the femur and proximal end of the tibia, involvement of the cervical spine is quite rare. Recently we observed a patient with a giant cell tumor affecting the sixth cervical vertebra. This is regarded as a clinically malignant tumor because its nature and difficulty in diagnosis and treatment We easily confirmed the extent of the lesion by CT scanning with Metrizamide. The treatment was palliative tumor ressection. This case of a giant cell tumor affecting the sixth cervical vertebra is reported with a brief review of the literature.

Since the first attemt of internal fixation not much more than a century ago, implants have come to play an important role in orthopaedic surgery. Yet little has been reported about complications which may result from implant surgery. During the period of May 1980 to April 1984, 32 cases of fixation failures were treated in the Department of Orthopaedic Surgery, Hallym College, Kang Nam Sacred Heart Hospital and results were obtained as follows: 1. The most common area involved femoral shaft, but the highest rate was distal femur. 2. The most common period of failure was between 2 to 4 months postoperatively. 3. The leading cause of failure was remaining defects at fracture site. 4. The authors recommend accurate reduction of fracture and bone graft, if necessary, adequate immobilization postoperatively and co-coperation of patient to avoid failure of implant.
