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.

A survey was conducted to study perception and attitudes of examinees of, health screening center towards items, cost and procedures of health examination and degree of satisfaction with health examination, from March 2 to May 31, 1995. The study population was 468 examinees received health examination at Health Screening & Diagnosis Center of Yeungnam University Hospital. A questionnaire method was used to collect data. The followings are summaries of findings Examinees were predominantly male(77.4%) ; had college education(68.6%), and held white-collar workers (57.8%).

BACKGROUND: The safety of ergonovine provocation for coronary vasospasm (CVS) performed outside the catheterization laboratory has been questioned. We sought to address the issues of safety, feasibility and clinical impact of noninvasive diagnosis of CVS. METHOD AND RESULTS: We retrospectively analyzed the results of bedside ergonovine provocation testing with monitoring of left ventricular regional wall motion abnormalities (RWMAs) by 2-dimensional echocardiography (ergonovine echocardiography, Erg Echo). After confirmation of no significant fixed epicardial coronary artery disease, 1,504 Erg Echo were performed in 1,372 patients from July 1991 to December 1997. Erg Echo was prematurely terminated in 13 patients (0.9%) due to limiting side effects unrelated with myocardial ischemia. Among 1,491 completed tests, 32% (477) showed positive results with development of RWMAs in 467 tests (98%) or ST displacement in ECG in 10 tests (2%). During the test, transient arrhythmias developed in 1.7% (26/1491) including transient ventricular tachycardia (2) and atrioventricular block (4), which were promptly reversed with nitroglycerin. There were no procedure-related death or development of myocardial infarction. On the basis of angiographic criteria in 218 patients, who also underwent invasive spasm provocation test during coronary angiography, the sensitivity and specificity of Erg Echo for the diagnosis of CVS were 93% and 91% respectively. From 1990 to 1997, total 2,073 spasm provocation tests were performed either during invasive coronary angiography in the catheterization or in the echocardiography laboratory. Since 1994, noninvasive Erg Echo became a more popular diagnostic method and comprised more than 95% of all spasm provocation tests in recent 3 years. Erg Echo was also performed safely in outpatient clinic setting without hospital admission in 34% (500/1491). CONCLUSIONS: Erg Echo is highly feasible, accurate and safe for diagnosis of CVS and can replace the invasive spasm provocation test during coronary angiography in the catheterization laboratory.

Systemic lupus erythematosus is a connective tissue disease which can affect every organ system. Neurologic abnormalities are common, occuring in approximately half of all patients at some time during the course of their illness. But symptoms of nervous system as the sole presenting symptoms occur in less than 1% of lupus patients. In patients initially presenting with neurologic symptoms and signs, differential diagnosis is difficult and sometimes it may be misdiagnosed. Therefore extensive laboratory investigations should be carried out in all patients with unusual neurological symptoms, since early diagnosis of lupus can help in providing effective treatment. We report a patient with systemic lupus erythematosus who presented with dysarthria and dysphagia resembling multiple sclerosis.

Cyclopia is rare congenital craniofacial anomaly, in which the eyes are fused together and located in a single orbit. It is consistently associated with severe holoprosencephaly, which is the failure of cleavage of the prosencephalon with a deficit in the midline facial development. chromosomal study revealed 47, X( ), +13 (Patau syndrome).

Vitamins and their metabolites are essential for many physiological processes including immune response. In addition to regulating calcium homeostasis, vitamin D exerts various effects on cells of the immune system, such as macrophages, dendritic cells as well as, B and T cells. Low vitamin D levels are found in patients with autoimmune diseases, which suggest a potential role of vitamin D in autoimmunity. In this review, we discuss the roles of vitamin D in modulating immune responses and the clinical potential of vitamin D metabolites for preventing and treating inflammatory and autoimmune diseases.

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.
