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.

OBJECTIVES: In order to standardize the CRP, ESR and WBC count after three types of spinal surgery and get clinical usefulness from these laboratory dadas after spinal surgery and clincal usefulness of laboratory datas. MATERIAL AND METHODS: Three groups of patients(microdisectomy, anterior and posterior fusion) were chosen for the study. CRP, ESR and WBC levels were prospectively determined before surgery and at days 1-5, 10, 14,21 and 42 after surgery. RESULTS: In all patients, preoperative normal CRP level(<10mg/L) increased, reaching peak levels on the second day after anterior fusion(84.6mg/L), and at the third day after microdiscectomy(54.5mg/L) and posterolateral intercorporal fusion(152.2mg/L), with normalization in 5-10 days. Preoperative normal ESR level increased to peak level on the forth day after microdiscectomy(33.0mm/hr), and increased double peak levels after anterior(postoperative days 2&5) and posterolateral intercorporal fusion(postoperative days 3&5). ESR followed by a slow and irregular decrease, and at 42 days after surgery often remained elevated. WBC increased to variable peak level within normal limit in all patients. CONCLUSIONS: The rapid decline in CRP will probably be interrupted by a second rise or persisting elevation if infection occurs. CRP is presumably a better test than ESR for early detection of postoperative infection.

We report a non-obese patient suffering from spastic gait and right leg paresis caused by thoracic spinal cord compression secondary to spinal epidural lipomatosis. Although spinal epidural lipomatosis is most often associated with the administration of exogenous steroid or endogenous Cushing syndrome, obesity also has been reported as a possible cause. However, idiopathic(non-glucocorticoid induced) spinal epidural lipomatosis in non-obese healthy man is an extremely rare disease and dose not have any good explanation for the abnormal fat deposition in spinal epidural space. We recently experienced a patient with idiopathic thoracic epidural lipomatosis in whom MRI and histopathology established the specific diagnosis. With a case report, brief review of the disease including clinical feature, diagnostic procedure and therapeutic considerations is described.

PURPOSE: To investigate the spontaneous cerebral microbleeding occurring at gradient-echo MRI, and its relationship with associated stroke lesions and risk factors. MATERIALS AND METHODS: Between September 2001 and December, 2002, 32 patients (21 men and 11 women; mean age 63 years) in whom cerebral microbleeding occurred at gradient-echo MRI were retrospectively investigated. Using a 1.5 T MR imager, spin-echo T1-weighted, fast spin-echo T2-weighted, diffusion-weighted, and gradient-echo images were obtained. The number and location of microbleeds seen on gradient echo images, patient data, and associated stroke lesions such as intracerebral hemorrhage and lacunar and territorial infarction were assessed. RESULTS: Among the 32 patients, 563 microbleeds and between 1 and 66 (mean, 17.6) were noted at gradientecho imaging. Microbleeding occurred in the cortical/subcortical area (n=216), the basal ganglia (n=173), thalamus (n=92), cerebellum (n=41), brainstem (n=36) and corpus callosum (n=1), and in 20 patients was bilateral. Patients had a history of hypertension (n=26), hypertriglycemia (n=12), heart disease (n=4), and diabetes mellitus (n=3). Stroke lesions were seen in 27 patients, intracerebral hemorrhage in ten, lacunar infarction in 24, and territorial infarction in four. CONCLUSION: The incidence and number of microbleeds was greater in older patients and in those with hypertension, hypertriglycemia, and stroke lesions such as intracerebral hemorrhage or lacunar infarction. The detection of microbleeding at gradient-echo imaging is helpful, since it predicts the possibility of cerebral hemorrhage in these patients.

The effects of NMDA-receptor antagonist (MK-801) were assessed for the oxygen free radical mediated brain (hippocampus) injury with eighty rats which were exposed to carbon monoxide (CO) followed by hyperbaric oxygen (HBO) treatment. Superoxide dismutase (SOD) and malondialdehyde (MDA) were used as parameters of the oxygen free radical reaction. Experimental groups consisted of (1) control group (=breathing with air), (2) CO group (=exposed to CO after air breath), (3) CO-air group(exposed to CO after air breath followed by air breath), and (4) CO-HBO group (=exposed to CO after air breath followed by 3 ATA HBO). Each group was divided two subgroup according to the pretreatment (normal saline or MK-801). CO, CO-air and HBO groups increased in SOD activity as compared with control group. And CO-air and HBO groups increased in MDA as compared with control and CO group. Pretreatment of MK-801 decreased SOD activities significantly (p-value<.05) , but MDA amount not significantly (p-value=.107). These results suggest a useful protective effect of NMDA-receptor antagonist (MK-801) in CO induced hippocampal injury mediated by oxygen free radicals.

PURPOSE: Burn injuries still produce a significant morbidity and mortality. The collection and analysis of burn epidemiology data would provide insights into new prevention management strategies in terms of nationwide profile. We reviewed and compared the data from other countries. METHODS: This study was carried out to analyze the epidemiology, current etiological factors (circumstances), treatment methods and mortality of 4,321 acute burn patients, excluding electrical burn, who were admitted to Hanil Hospital Burn Center during 12 years (1996~2007). RESULTS: 1) The male to female ratio was 1.3:1. The mean age of admission was 30.0 years. The children below 18 years made up 38.9%, and adult over 60 years 10.2%. 2) The scald was the most common cause making up 53.8% followed by flame (30.8%), contact (9.3%), steam (3.6%) and chemical (2.1%) burn. The mean extent was 9.8%, 19.1%, 3.8%, 7.2%, 8.7% respectively. 3) The etiologies of scald burn were boiled water (32.9%), hot food soup (28.1%), boiling water (13.8%), instant food (10.3%) at home (87.4%). The 13.7% of victims underwent surgery of STSG (12.9%), FTSG (0.6%), local flap (1.2%) and advanced flap (0.1%). 4) The majority of flame burn occurred at home (43.7%) and work place factory (23.5%). Leading causes were inflammables (29.3%), fire (14.0%), explosion of butane can (12.8%), gas range (10.1%) and LPG (8.7%). The 31.4% of victims underwent STSG (26.2%), FTSG (0.8%), local flap (0.2%) and major amputation (0.1%). 5) The major victims (50.6%) of steam were children below 2years by exposing to steam of rice cooker (70.0%) at home. The 28.9% of victims underwent STSG (14.7%), FTSG (16.0%) and local flap (5.1%). 6) The contact burns occurred at various places (home; 56.5%, work place; 16.9%, vehicles; 9.0%, sauna; 4.5%) by various causes (Ondol; 11.9%, hot pack; 11.2%, oriental herb medicine; 6.7%). The 45.8% of victims underwent STSG (36.3%), FTSG (6.7%), local flap (5.2%), advanced flap (2.0%) and minor amputation (1.2%). 7) The chemical burn occurred at various place (home; 39.3%, work place; 49.4%) by acids (43.8%), alkalies (11.2%), vinegar (15.7%) and herb moxa (16.9%). The 28.1% of victims underwent STSG (22.5%), FTSG (9.0%), local flap (7.9%) and minor amputation (6.7%). 8) Children<18 years old were burnt mainly by scald (79.0%) while for adults below 50 years old was flame, over 50 years was scald. Children below 2 years old had higher frequency of steam (9.2%) and contact (7.9%) burn. The contact burn had relatively higher frequency among 7th (17.6%) and over 8th (20.4%), while chemical among 6th (3.9%) decade. 9) Inhalation injury was accompanied in 13.8% of flame burn (4.3% of total). The inhalation injury only was 4.9% of flame (1.5% of total). 10) The overall mortality rate was 1.8%. The mean age of death was 47.3 years old and burn extent was 74.5%TBSA. There was a strong correlation between flame burn (96.2% of total death), TBSA (50~60%; 9.3% vs 70~80%; 65.2%, 80~90%; 71.4%, over 90%; 87.9%) and mortality. The prognosis was poor for those over 70 year old (7.7% vs 30~50 yo; 2.8%, 7 th decade; 3.7%), flame burn (5.6% vs scald; 0.04%) and combined inhalation injury (22.3%). The patients died at mean 17.3 PBD by ARDS (51.3%), sepsis (44.9%), burn shock (20.5%) and ARF (5.1%) 11) The severity and sequelae of scald by prepackaged instant food, steams of rice cooker, flame by used butane can, contact by Ondol, sauna and chemical by vinegar should be added to preventive programs. CONCLUSION: Further study for implications of changes in management protocols and policies on treatment outcomes would improve the provision of appropriate care for the patients.

Lyme disease, a multi-systemic infection occurring worldwide, has yet to be reported in Korea, although the spirochete B. burgdorferi, known as the causative organism of the disease, has recently been isolated from the vector tick Ixodes persulcatus in the region. To contribute to revealing whether Lyme disease exists in Korea or not, B. burgdorferi specific antibodies (IgG, IgM, and/or IgA) were measured by three individual enzyme-linked immunosorbent assays (ELISA) utilizing different antigens in 38 patients with juvenile rheumatoid arthritis (JRA) which shares a number of clinical features with Lyme arthritis. The antibody prevalence rates in patients with JRA were various depending on the antigens (21% of IgG and IgM antibodies to purified organisms, 0% for IgG antibody to purified native flagella, and 5% for IgG, IgM, and IgA antibodies to recombinant p39) and were not different compared to 39 controls (21%, 0%, and 0% respectively). The antibody prevalence rates compared in various subgroups of patients with JRA according to types of JRA, length of illness, age, and sex were not different. Comparing the three different antigens, the greatest number of positive responders were yielded by purified organisms followed by p39 and purified flagellin, however the possibility of nonspecificity with purified organisms remained. The data indicate that serologic tests using ELISA fail to illustrate Lyme disease among 38 patients with JRA in Korea.
