We report a case of calcinosis cutis following administration of 10% calcium gluconate, used for the treatment of a hypocalcemic seizure in a 5-week-old neonate. After administration of 10% calcium gluconate, subcutaneous induration developed at the infusion site. The histopathological findings taken from the dorsum of the left foot showed multiple foci of calcium deposits with infiltration of epitheloid histiocytes between collagen bundles and foreign body giant cells phagocyting calcific granules throughout the reticular dermis and subcutis.

p21 is a universal inhibitor of cyclin-dependent kinase (cdk) and of cell-cycle progression. p21 expression is variable according to the type of tissue and the pathologic condition. To study the role of p21 in the multistep hepatocarcinogenesis, the expression of p21, p53 and Ki-67 was investigated in 53 cases of inactive liver cirrhosis, 4 cases of low grade dysplastic nodules, 3 cases of high grade dysplastic nodules, 7 cases of early hepatocellular carcinomas (HCCs), 27 cases of small HCCs (< or =3 cm), and 52 cases of advanced HCCs (>3 cm). p21 expression was not detected in liver cirrhosis, low grade dysplastic nodules, high grade dysplastic nodules and early HCCs which were mitotically inactive. p21 expression was significantly increased in small HCCs and advanced HCCs which were mitotically active. p21 expression was significantly correlated with Ki-67 labelling indices. p53 protein was not expressed in liver cirrhosis, dysplastic nodules, and early HCCs. The expression of p53 protein was, however, significantly increased in small and advanced HCCs. The p21 expression was not correlated with p53 expression. Therefore, p21 is suggested to play a role in the mitotically active small and advanced HCCs, but not in the mitotically inactive lesion of dysplastic nodules and early HCC in multistep hepatocarcinogenesis. These findings suggest that homeostatic mechanism of growth control is not totally destroyed in HCC.

The lower ureter is not so frequent site of the urinary tract obstruction. In lower ureteral obstruction, the obstruction should be relieved by any method for maintaining renal parenchyme. A clinical studies were made on the 24 ureters of the lower ureteral obstruction. This studies were mainly focused on the method of management by internal stent indwelling. The following results were obtained. 1. In etiology, acquired lower ureteral strictures were most common ; tuberculosis in 10 ureters, radiation in 6 ureters, pelvic lymphadenopathy in 4 ureters, and iatrogenic stricture in 3 ureters. Congenital UVJ stricture was only one ureter. 2. In the method of management, open surgeries were done in 10 ureters and endourologic methods in 14 ureters. 3. In 5 failures of the first management, open surgeries were done in 3 ureters and endourologic methods in 2ureters. The tuberculosis was the most of their etiology. 4. Complications in internal stent indwelled cases were flank pain, severe vesical irritation, migration into the bladder and the obstruction of the lumen of stent.

Gastric glomus tumor is an uncommon benign, submucosal neoplasm and does not require radical surgical procedure. Because there are no specific clinical or radiologic features associated with the glomus tumor, it can be recognized only by its histologic characteristics. We report a 30-year-old woman who had 10 years history of epigastric hunger pain. Radiologically, a gastric submucosal tumor was discovered, which was suggestive of leiomyoma. Gastric antrectomy was performed. The tumor cells showed immunohistochemical and ultrastructural evidence of smooth muscle differentiation.

During 1964 to 1967, a survey of 30,534 persons for filariasis was made on all over the country with the following results: Among 24,816 draftees from all over the country in the army recruitment camp 155(0.63 %) were found infected with Brugia malayi. Cheju Do showed the highest microfilaria rate(3.5 %), North Kyongsang Do(1.4 %) the next and South Cholla Do(1.2 %) the third. Blood films from 2,308 inhabitants were examined and 407(17.6 %) showed microfilaria in Cheju Do. 30(3.1 %) out of 974 inhabitants in North Kyongsang Do were found to be infected. The microfilaria rates were 2.0 per cent for 400 inhabitants of Chindo island in South Cholla Do. However, no positive case of microfilaria was found in the inhabitants of Kokumdo among 1,820 persons examined in South Cholla Do and of Namhae island(among 165 persons examined) in South Kyongsang Do. The mean microfilarial density per 20 cu. mm of blood was 52.6 in the inhabitants of Cheju Do, 12.2 in North Kyongsang Do and 27.3 in Chindo island(South Cholla Do). Any distinct relationship between the incidence of positive cases of microfilariae and age or sex of the cases was not observed in Cheju Do. However, in Norh Kyongsang Do and South Cholla Do the microfilaria rate of the male group is higher than the one of the female group of the inhabitants. From the above survey results it turned out that filariasis was found throughout Southern Korea except Kyonggi Do and South Kyongsang Do. A total 30,534 persons examined, 601(2.0 %) were found to be infected by Brugia malayi. Therefore, it seems that there are some endemic foci of malayian filariasis in three main areas such as North Kyongsang Do, South Cholla Do and Cheju Do.

In the Workers' Compensation Insurance (WCI) system in Korea, occupational diseases (ODs) are approved through deliberation meetings of the Committee on Occupational Disease Judgment (CODJ) after disease investigations when workers or medical institutions requested the Korea Workers' Compensation and Welfare Service (COMWEL) for medical care benefits. Insufficient data presented by employers or workers or lack of objective evidence may increase the possibility of disapproval. The expertise of accident investigation staff members should be reinforced and employers' and related institutions' obligations to cooperate and submit data should be specified under the law. The deliberation meetings of the CODJ are held separately for musculoskeletal, cerebro-cardiovascular, and medical diseases, and the judgments of ODs are made by the chairperson of COMWEL and six committee members by majority vote by issue. To reinforce the expertise of the members of the CODJ, periodic education and a system to accredit the committee members after appropriate education should be introduced. To fairly and quickly compensate for diseases that occur in workers, the criteria for the recognition of occupational diseases should be continuously amended and the systems for disease investigations and judgments should be continuously improved.
