The second case of this serial reports under the title of unusual cutaneous manifestations of connective tissue diseases is a woman with primary idiopathic dermatomyositis who developed cutaneous ulcerations on her arms and legs, which is thought to b a rare manifestation of adult dermatomyositis. These multiple ulcerations are about bean sized, polymorphous, and grouped on the poikilodermatous lesional skin. In this patient these ulcerative lesions became regressive and healed with disfiguring scars after the activity of the disease has controlled by prednisolone and methotrexate.

The objective of cancer screening is to reduce the risk of death, i.e., mortality from cancer among individuals subjected to screening. For cervical and colorectal cancer, the screening test is aimed at detection of preinvasive lesions. Therefore, reduction in the incidence of invasive disease also results from screening. In a national cancer control program, the programs should be orgainzed to ensure that a large proportion of the target group is screened and that those individuals in whom abnormalities are abserved receive appropriate diagnosis and therapy. Agreement should be reached on guidelines to be applied in the national cancer control program. When establishing appropriate cancer screening recommendations several factors should be considered. ① For establishing the starting age, age-specific incidence and mortality rate, life lost person-years, and cost-effectiveness can be considered. ② For frequency of screening, it is necessary to understand the natural history of disease. ③ For choosing the best test tool, sensitivity and specificity, compliance, cost, and adverse effects can be considered. It seems that doctors' willingness to participate is essential for a successful cancer screening program. They should understand the rationale of cancer secreening, its effectiveness, and the risk.

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.

The bone mineral densities of 60 middle school boys were measured with dual photon absorptiometry to define the influence of Taekwon-Do. They were divided into Taekwon-Do and control group, each comprising 30 boys. The bone mineral densities of the head, trunk, pelvis, both upper and lower extremities, and body total were measured. The results were as follows. 1. The BMD of head was 1.668 ± 0.153 in Taekwon-Do and 1.554 ± 0.153 0.167 in control. It was significantly increased in aekwon-Do(p <0.05). 2. The BMD of trunk was 0.378 ± 0.153 0.044 in Taekwon-Do and 0.353 ± 0.153 0.053 in control. There was no significant difference(p >0.05). 3. The BMD of pelvis was 1.648 ± 0.153 0.112 in Taekwon-Do and 1.444 ± 0.153 0.215 in control. It was significantly increased in Taekwon-Do(p <0.005). 4. The BMD of right and left legs were 1.597 ± 0.153 0.118 and 1.579 ± 0.153 0.125 in Taekwon-Do and 1.425 ± 0.153 0.115 and 1.421 ± 0.153 0.113 in control group respectively. They were significantly increased in Taekwon-Do(p <0.005). 5. The BMD of right and left arms were 1.184 ± 0.153 0.090 and 1.178 ± 0.153 0.115 in Taekwon-Do and 1.056 ± 0.153 0.095 and 1.066 ± 0.153 0.097 in control group respectively. They were significantly increased in Taekwon-Do(p.<0.005). 6. The total body BMD was 0.932 ± 0.153 0.068 in Taekwon-Do and 0.846 ± 0.065 in control. It is significantly increased in Taekwon-Do(p<0.005). In conclusion, Taekwon-Do increases the total bone mineral density and the mineral densities of the head, pelvis and extremities but not that of trunk. It is thought that continued practice of Taekwon-Do throughout adult life might prevent the senile osteoporosis

We present a patient who developed a pseudolymphoma after ear piercing. A patch test showed gold sensitivity. Therefore, long standing dermal exposure to gold from a pierced-type earring might have produced the patient's disease. This patient did not respond to an intralesional steroid injection and was finally treated with a complete resection of the lesion. It is proposed that every patient with a hyperplastic lesion in the ear lobe should be taken a biopsy in order to rule out the possibility of a pseudolymphoma. When a pseudolymphoma develops in the ear lobe, a complete surgical excision could be the treatment of choice, especially for the prevention of recurrence.

PURPOSE: Abdominal CT scans in patients with intraperitoneal fluid were retrospectively studied to identify characteristic features useful for differential diagnosis of various causes. MATERIALS AND METHODS: One hundred and seventy patients with intraperitoneal fluid collection were classified as categories of hepatic disease, carcinomatosis, and infectious disease. We analyzed sites of fluid collection, the presence of peritoneal thickening, omental and mesenteric fat infiltration, and lymph node enlargment. RESULTS: Intraperitoneal fluid was present in subhepatic space, subphrenic space, paracolic gutter, mesentery, and fossa of the gallbladder in decreasing order of frequency. Fluid in the gallbladder fossa was the most frequent in hepatic diseases. The fluid collection in subhepatic and subphrenic space was less frequent in infectious diseases. Peritoneal thickening was noted in infectious diseases, and carcinomatosis. Omental fat infiltration and enlarged lymph nodes were the most frequent in carcinomatosis (58% and 44%, respectively), whereas, mesenteric fat infiltration and enlarged lymph nodes were the most common in infectious diseases (61%, and 26%, respectively). CONCLUSION: The location of peritoneal fluid collection showed some lesion specific characteristics, and CT features of fat infiltration and enlarged lymph nodes of peritoneum, omentum, and mesentery were helpful for differential diagnosis between carcinomatosis and infectious diseases.

In order to provide some basic data for the control of air water pollution in Korea, the suthors have estimated the amount of air and water pollutant emitted from industries which are employed over 20 employes. This study have done from July 1, 1972 to the end March 1973. The results are as follows: 1. Total number of establishments tith over 20 employees is 5,197 in Korea and the largest gorup establishments was the manufacturing of texttiles with 1,363 establishments(26.2%). 2. By order of number of employees it was observed that there 2,800 industries with 20-59(53.9%) employees, 1,101 with 50-99(21.2%), 571 with 100-199(11.0%), 501 with 200-499(9.6%) and 225with over 500(4.3%) respectively. 3. By order of regional distribution, it was observed that there were 2,257 industries in Seoul (43.3%) and 736 industries in Pusan(14.2%). 4. Industrial coal consumption was 596,154 M/T in 1972, but it'11 be 315,000 M/T in 1980, Fuel consumption was 4,972,000 K1 in 1972, and estimated volume will be 19,3700,000 K1 in 1980. 5. Ttotal amounts of air polutants emitted from industris by fuel combustion were sulfur oxides 79,459 tons, carbon monoxide 33,908 tons, particulate 31,304 tons and hydrocarbon 30,280 tons in 1972 but in 1990 there will be sulfur oxides 1,010,474 tons, nitrogen oxides 204,575 tons, carbon monoxide 68,014 tons, particulate 64,820 tons and hydrocarbon 67,622 tons, respectively. 6. Annual emitted air pollutants through the working processes were sulfur oxides 91,250 tons and nitrogen oxides 32,485 tons in 1972, but sulfur oxieds 118,625 tons and nitrogen oxides 42,555 tons will be present in 1980, respectively. 7. Annual emitted air pollutants by national unit area amounted to 0.77 tons/km2/year in 1965 and 14.7 ton/km2/year in 1980. 8. Total industrial wastes from all industries in Korea were estimated at 810,360 tons/day in 1972; manufacturing of chemicals and plastic products showed the highest amount of wastes at 470,000 tons/day. 9. The amounts of water pollutants due to industrial wastes were the .B.O.D., 471.5 tons/day,suspended solid 331.5 tons/day, CN, 2.3 tons/day, and Cr. 3. 4 tons/day in 1972, but it might be evident of a B.O.D of 3.388 tons/day, suspended solid 2,544 tons/day, CN 20.1 tons/day, and 26.5 tons/day in 1990. 10. Total population equivalent of B.O.D. was 943,000 in 1972, and the estimated value in 1990 will be6, 780, 000.
