Pleomorphic xanthoastrocytoma is histologically characterized by marked cellular pleomorphism of lipid-laden neoplastic astrocytes and bizarre giant cells showing mitotic figures and high cellularity. Inspite of its ominous-looking microscopic features, howerver, the prognosis is usually favorable. This tumor develops mainly in the supratentorial area of young people and frequently involves the leptomeninges. We experienced a case of pleomorphic xanthoastrocytoma in 18 year-old-male. In addition to the cellular pleomophism, the prominent reticulin fibers surround the individual tumor cells or the tumor cells nests. Immunohistochemical staining and electron microscopy revealed glial fibrillary acidic protein(GFAP) expression and pericytoplasmic basal lamina in the tumor cells.

To knew the prevalence and nature of asymptomatic microscopic hematuria in a community. we evaluated 13,678 cases(M; 12.198 cases, F; 1,480 cases) that visited to the Department of Health Service. Kang Nam General Hospital from April to October, 1992 for annual physical examination. For the detection of hematuria urine dipstick test was done. and then urine microscopy was done in cases with positive dipstick test (262 cases). Hematuria was defined as 3 or more RBCs/HPF on microscopic examination of the urinary sediment(189 cases). Repeated urinalysis was done in cases with 3-4 RBCs/HPF (30 cases). And in cases with 5 or more RBCs/HPF on urine microscopy, excretory urography(105 cases) was primarily checked and in addition, renal ultrasonography. cystoscopy. RGP. urine culture. urine cytology. serum IgA, C3. C4 were performed for investigation ofThe results were as follows: I. Prevalence of asymptomatic microscopic hematuria was 1.38% and significantly increased with age (p<0.01). 2. Urologic abnormalities associated with hematuria were identified in 23 cases (21.9 %)-6 cases of renal stone. 4 cases of BPH. 4 cases of UPJ stricture, 3 cases or cystitis, 2 cases of ureteral stone. 1 case or ureteral stricture. nephroptosis. renal cyst. renal tuberculosis. S. In 82 cases, urologic abnormalities could not be found and then serum IgA. C3 C4 checked in 36 cases among these. IgA was increased in 21 cases (58.3%). From the above result. the causes of asymptomatic microscopic hematuria in adults could not be found in 78.1% and serious urologic diseases tumor and so on) were almost not found. We conclude that in order to obtain the detection of accurate prevalence and various urologic diseases. repeatedurine dipstick test and long-term followup in larger populations would be needed, and that screening test for the evaluation of hematuria would consist of performing excretory urography only in relative young adults and excretory urography with selective urine cytology after age 50 years.

Cerebro-cardiovascular disease (CVD) is one of compensable occupational diseases in Korea as in Japan or Taiwan. However, most countries accept only cardiovascular diseases (ischemic heart diseases) as compensable occupational diseases if any, but not cerebrovascular diseases. Korea has a prescribed list of compensable occupational diseases. CVD was not included in the list until 1993. In the early 1990s, a case of cerebral infarction was accepted as occupational disease by the Supreme Court. The decision was based on the concept that workers' compensation system is one of the social security systems. In 1994, the government has established a diagnostic criterion of CVD. The crude rate of compensated cerebrovascular disease decreased by 60.0% from 18.5 in 2003 to 7.4 in 2008 per 100,000 workers, and that of compensated coronary heart disease decreased by 60.5% from 3.8 in 2003 to 1.5 in 2008 per 100,000 workers. The compensated cases of CVD dramatically increased and reached its peak in 2003. Since many preventive activities were performed by the government and employers, the compensated cases have slowly decreased since 2003 and sharply decreased after 2008 when the diagnostic criterion was amended. The strategic approach is needed essentially because CVDs are common, serious and preventable diseases which lead to economic burden.

PURPOSE: The purpose of this study was to describe the anglographic finding and clinical result of transarterial embolotherapy(TAE) in patients with injuries of renal artery branches by blunt trauma. MATERIALS AND METHODS: The study was based on retrospective analysis of seven cases, in which TAE was attempted for the control of traumatic renal arterial bleeding. All procedures were performed via the transfemoral approach. TAE was performed with stainless steel coil in two cases, Gelfoam in one case, and Gelfoam and stainless steel coil in four cases. RESULTS: Angiographic findings of vascular injuries were pseudoaneurysm in four cases, extravasation in two cases and arteriocalyceal fistula in one case. All procedures were performed successfully without complication. CONCLUSION: Pseudoaneurysm is a common anglographic finding in patients with injury of renal artery branches and TAE is considered a safe and effective method for treating such cases.

Serum prostate specific antigen (PSA) and prostate acid phosphatase (PAP) were measured in 106 patients including 9 patients with prostate cancer, 63 patients with BPH. and 34 normal control group free of prostate disorders. The mean PSA value was 61.14+/-43.87 ng/ml for prostate cancer, 6.07+/-5.57 ng/ml for BPH and 1.42+/-0.98 ng/ml for normal control group, and the mean PAP value was 9.81+/-10.16 ng/ml for prostate cancer, 1.58+/-2.36ng/ml for BPH and 1.00+/-0.17 ng/ml for normal control group. The positive rates of PSA were 78% for prostate cancer, 22% for BPH and 0% for normal control group, and those of PAP were 67% for prostate cancer, 6% for BPH and 0% for normal control group. The sensitivity and specificity for PSA were 78%, respectively. We conclude that PSA may be a useful tool for detection and therapeutic monitoring of the prostatic cancer.

In order to evaluate the effects of trichloroethylene (TCE) on the central and autonomic nervous system, the brain stem auditory evoked potentials (BAEPs) and the electrocardiographic R-R interval variability (CV(rr)) were measured in three groups of workers (11) working in TCE degreasing process, workers (4) exposed to lead and two groups of workers (12) not exposed to any kinds of neurotoxicants. Two components of the CVrr reflecting parasympathetic activity (C-CV(rsa)) and sympathetic and parasympathetic activities (CCV(mwsa)) were examined. The TCE workers were exposed to TCE at the level of less than 1 hour per week while the degreasing material was changed. There were no differences in the latencies of BAEPS and CV(rr) and the components of the CV(rr) between control and TCE and lead groups. However, two lead workers had the blood lead level of less than 60 g/dl recommended as present biological guideline by the Ministry of Labor, showed the delayed latencies of V5 and I-V in BAEP. This results suggested that intermittent TCE erposure didn't affect the auditory nervous pathway and the autonomic nervous system, however, lead exposure might affect the central nervous system at the level of less than 60 g/dl in blood lead.

Work-related Musculoskeletal Disorders (WMSDs) arising from repetitive work, awkward working postures and exerted force have the potential to occur in almost every workplace. In 2007, WMSDs took 67.3% of the total occupational diseases compensated as industrial accident. Firefighters in particular, are more exposed to the risks of low back pain because they encounter many cases of excessive exertion in unexpected situations. However, the employer (government) and the employees (firefighters) awareness on WMSDs is rather low when compared to the attention given to the industrial accidents. Firefighters' tasks include lifting, lowering, pushing, pulling and moving heavy objects with fully equipped turn out gear. These assigned tasks require excessive force and often occur in uncomfortable situations. In some cases, tasks are performed in undesirably high or low temperature environments. Some workers such as emergency call operator retain a static position for long working hours. In addition, the boundaries of fire protection tasks in Korea have extended to include emergency management since 1999, exposing firefighters to the greater risks of WMSDs. According to the U.S. National Fire Protection Association report, strain and sprain took more than 40% of injuries occurred during fire ground operation in 2005. In Korea, 2007, it was reported out of 30,630 firefighters, 279 were involved in work-related accident or injury. Even though there was no exact information reported on WMSDs, it must be acknowledged that during performing fire protection tasks, injuries including low back pain, sprain, strain, and more easily occurs. Also when treating the injured fire prevention related workers, its work-relatedness must be considered, because prevention will become a reality only if work-relatedness is fully understood. Therefore, in order to reduce the occurrence of WMSDs in fire protection related workers, risk factors of WMSDs must be continually reviewed and managed, and all workers must be educated on WMSDs prevention.
