Industrial Accident Compensation Insurance (IACI) has a history of about 50 yr, and is the oldest social insurance system in Korea. After more than 20 times of revision improvements in benefits, its contents and claim systems have been upgraded. It became the protector of injured workers and their families, and at the same time became the system which could cope with both financial burden of employers and their responsibilities. However, there are some issues to be reformed to upgrade the IACI: 1) the problems in the approval system of occupational diseases, 2) quality improvement of workers' compensation medical care, 3) vocational rehabilitation and return to work, 4) workers' compensation premiums and out-of-pocket money of injured workers, 5) issues in application of IACI. Growth of IACI cannot be achieved by an effort of an individual. Efforts by workers, owners, and government, in addition to physicians and welfare professionals toward the same goal are required for the next level improvement of IACI.

Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease resulting from infection of oligodendrocytes with JC virus. PML was a rare disease, but nowadays not uncommon as AIDS prevailed. Histopathologic features of the affected lesion shows infiltrations of foamy macrophages and hyperchromatic, pleomorphic, reactive astrocytes that may raise the suspicion of a brain tumor. We recently met with 3 cases of PML. Two of the patients had AIDS and the other had been treated for lymphoma. All cases were diagnosed by histopathologic examination in stereotactic brain biopsies.

Unilateral renal agenesis associated with genito-urinary disease was found in 2 siblings of a single family. There are a few reports of familial unilateral renal agenesis. Bilateral renal agenesis is a fetal condition and unilateral renal agenesis or hypoplasia is usually asymptomatic, so investigations for renal anomalies have not been frequently undertaken in healthy members of families in which bilateral agenesis has occurred. The present report suggests that unilateral renal agenesis could occur as a manifestation of a genetic disorder.

OBJECTIVES: Recirculation is one of the factors preventing effective hemodialysis(HD) and one of the methods which can detect vascular access stenosis. We analyzed the possible clinical risk factors and relationship between the recirculation rate(R) and adequacy of hemodialysis. Also, we attempted to find out whether vascular access stenosis actually exist in the high R group. METHODS: We examined the period of hemodialysis, the presence of diabetes mellitus(DM), use of artificial grafts, the venous pressure(VP) during HD, the difference(deltaKt/V) between prescribed Kt/V(Kt/V') and delivered Kt/V(Kt/V") in 113 patients(22 DM, 39 artifical graft patients) receving maintenence HD. R was obtained by two needle slow flow method. Fistulogram was performed in the high R group(R>10%) and if significant stenosis was found, surgical correction was performed followed by repeated R, VP, Kt/V" measurement. RESULTS: As a whole R was 5.6%(+/-8.8), VP was 92mmHg(+/-44), the duration of hemodialysis was 36 months(+/-25) and Kt/V" was 1.20 (+/-0.29). The VP of the group with artificial graft was higher than that of the group with native fistula, but there was no relationship between R and duration of HD, Kt/V", deltaKt/V as a whole. The VP and deltaKt/V of group with high R(>10%) were significantly higher than the group with low R(<10%). Positive correlation between R and deltaKt/V was demonstrated in the group with high R. In six patients with high R, fistulograms were taken and significant vascular stenosis were found. After surgical correction, R was significantly decreased from 25.5% to 5.2%. On the other hand, the R as well as the rate of diabetes or prosthetic grafts were higher in the group with high VP(>or=100mmHg) than in the group with low VP(<100mmHg) as well as in patients with diabetes or prosthetic grafts, CONCLUSION: We believe recirculation should be measured during maintenance HD especially when the patient has diabetes, artificial graft or high venous pressure during HD. When the recirculation rate is high, reconstructive vascular surgery with proprer mediacl management may lead to better dialysis adequacy.

Marchiafava-Bignami disease (MBD) is a rare alcohol-related disorder that results in progressive demyelination and necrosis of the corpus callosum. The process may extend to the optic chiasm and tracts, cerebellar peduncle, subcortical resion, neighboring white matter, and rarely, cortical gray matter. We report a case of MBD in which fluid-attenuated inversion recovery and diffusion magnetic resonance imaging studies revealed symmetrical hyperintense lesions in the cerebral cortex in addition to the callosal lesions.

Thyrotoxic storm is an extreme state of thyrotoxicosis and a medical emergency. The clinical presentation of thyrotoxic storm includes tachycardia, fever, organ effect of central nervous system, cardiovascular system, and gastrointestinal system dysfunction. It usually occurs in patients with untreated or partially treated Graves' disease. Although it is rare, its mortality rate has reached 10-20%. There are no specific tests for establishing the diagnosis; it can only be diagnosed based on the clinical expression and laboratory results. Rapid diagnosis and treatment are necessary when it unexpectedly occurs during the perioperative period. We report a case of unnoticed hyperthyroidism that was diagnosed due to thyrotoxic storm-induced tachycardia in the post anesthesia care unit.
