Spinal epidural hematoma results from various causes such as use of anticoagulants, hemorrhagic diathesis, pregnancy, labor, arteriovenous malformation and spinal anesthesia as well as idiopathic orgin. We report a 3-year-old boy who was found to have spinal epidural hematoma and presented with lower back pain and fever. He developed paraplegia of lower legs after two consecutive lumbar punctures during two days. The lesion of spinal epidural hematoma was not found with lumbar spinal MRI but with cervico-thorasic one, because the lesion was at the C7-T6 level. Laminectomy was done to evacuate the hematoma and some specimen was obtained, of which pathologic finding was arteriovenous malformation. The boy is receiving physical therapy continuously due to unsatisfactory results with hematoma aspiration procedure and laminectomy treatment.

OBJECTIVE: To describe factors associated with the severity of post-stroke dysphagia. METHODS: We reviewed retrospectively medical records of patients having dysphagia following stroke in Seoul National University hospital from April 2002 through Dec 2009. A total of 578 patients (male and female, 331 and 247) were included. The following parameters were recorded and analyzed: patient's sex, age, type of stroke, onset of dysphagia, location of lesion and the American Speech-Language-Hearing Association National Outcome Measurement System Swallowing Scale (ASHA NOMS). Using Binary logistic regression and multiple regression analysis, the relationship between dysphagia severity and other factors were analyzed. RESULTS: Their average duration between onset of stroke and the date of videofluoroscopic swallowing study (VFSS) was 32.3 +/- 18.4 days. Patients with hemorrhagic stroke (172 patients, ASHA 4.06 +/- 1.98) showed poorer swallowing function than those with ischemic stroke (406 patients, ASHA 4.49 +/- 2.02, p=0.013). Binary logistic regression analysis showed that patients who had longer duration from onset to the first study, hemorrhagic stroke, bilateral lesion and older age were at higher risk for dysphagia requiring non-oral supplements (p=0.031, 0.039, 0.042, and 0.043, respectively). Multiple regression analysis revealed that longer duration from onset to study, older age and hemorrhagic stroke were associated with the lower ASHA NOMS (p=0.006, 0.009 and 0.021, respectively). Bilateral lesion, sex, history of previous stroke and involvement of the brainstem, however, were not significant factors. CONCLUSION: Hemorrhagic stroke, longer duration from stroke onset to the initial evaluation, and older age were identified as associated factors with the poorer swallowing function after stroke. Further prospective studies will be required to evaluate the prognostic value of these characteristics.

Previously, we constructed a humanized antibody (HuS10) that binds to the common a antigenic determinant on the S protein of HBV. In this study, we evaluated its HBV-neutralizing activity in chimpanzees. A study chimpanzee was intravenously administered with a single dose of HuS10, followed by intravenous challenge with the adr subtype of HBV, while a control chimpanzee was only challenged with the virus. The result showed that the control chimpanzee was infected by the virus, and thus serum HBV surface antigen (HBsAg) became positive from the 14th to 20th week and actively acquired serum anti-HBc and anti-HBs antibodies appeared from the 19th and 23rd week, respectively. However, in the case of the study chimpanzee, serum HBsAg became positive from the 34th to 37th week, while actively acquired serum anti-HBc and anti-HBs antibodies appeared from the 37th and 40th week, respectively, indicating that HuS10 neutralized the virus in vivo and thus delayed the HBV infection. This novel humanized antibody will be useful in the immunoprophylaxis of HBV infection.

OBJECTIVE: This study was aimed to identify the incidence and risk factors of vancomycin-resistant enterococcus (VRE) colonization in neurosurgical practice of field, with particular attention to intensive care unit (ICU). METHODS: This retrospective study was carried out on the Neurosurgical ICU (NICU), during the period from January. 2005 to December. 2007, in 414 consecutive patients who had been admitted to the NICU. Demographics and known risk factors were retrieved and assessed by statistical methods. RESULTS: A total of 52 patients had VRE colonization among 414 patients enrolled, with an overall prevalence rate of 6.1%. E. faecium was the most frequently isolated pathogen, and 92.3% of all VRE were isolated from urine specimen. Active infection was noticed only in 2 patients with bacteremia and meningitis. Relative antibiotic agents were third-generation cephalosporin in 40%, and vancomycin in 23%, and multiple antibiotic usages were also identified in 13% of all cases. Multivariate analyses showed Glasgow coma scale (GCS) score less than 8, placement of Foley catheter longer than 2 weeks, ICU stay over 2 weeks and presence of nearby VRE-positive patients had a significantly independent association with VRE infection. CONCLUSION: When managing the high-risk patients being prone to be infected VRE in the NICU, extreme caution should be paid upon. Because prevention and outbreak control is of ultimate importance, clinicians should be alert the possibility of impending colonization and infection by all means available. The most crucial interventions are careful hand washing, strict glove handling, meticulous and active screening, and complete segregation.

The incidence of tuberculoma of the brain in different countries varies reatly. They form a high percentage of intracrnial lesions dealt with in countries of Asia, Eastern Europe, Italy, Spain and South America. The recent introduction of the potent antituberculosis remedies, far from diminishing the incidence of tuberculoma of the brain, is more likely to increase it. This case was a 18 year old male who had increased intracranial pressure signs and characteristic signs which was suggestive lesion in posterior fossa. Conray ventriculography revealed nearly total obstruction of distal portion of aqueduct of Sylvius with displacement to the right side. Intensive antituberclous treatment then was started after removal of tuberculoma in cerebellar vermis and then discharged with fully recovery. References were reviewed as will.

Objective: A prolonged length of stay in the emergency department (EDLOS) is known to be associated with poorer outcomes in critically ill patients. However, this has not been proven in patients who visit the emergency department (ED) due to acute heart failure (AHF). We aimed to find out whether prolonged EDLOS is associated with major in-hospital complications in patients with AHF. Methods: This is a retrospective cohort study of AHF patients who were admitted to intensive care units (ICU) via the ED of a single academic hospital from January 2015 to December 2019. We divided the patients into two groups: EDLOS <24 hours and EDLOS≥24 hours. The primary outcome was major in-hospital complications, which included in-hospital death, application of continuous renal replacement therapy, or extracorporeal membrane oxygenation treatment. Secondary outcomes included in-hospital death, prolonged ICU stay (≥10 days), and prolonged hospital stay (≥14 days) excluding ED stay. Results: A total of 265 patients were enrolled. Of these 163 patients stayed in the ED for over 24 hours. The multivariable logistic analysis demonstrated that EDLOS ≥24 hours was independently associated with major in-hospital complications (odds ratio [OR], 3.296; 95% confidence interval [CI], 1.291-8.413; P=0.013). Analysis of the secondary outcomes showed that EDLOS ≥24 hours was associated with in-hospital death (OR, 2.607; 95% CI, 1.005-6.759; P=0.049) and prolonged hospital stay ≥14 days (OR, 2.458; 95% CI, 1.303-4.636; P=0.006). Conclusion Our study showed that in patients with AHF who visited ED and were admitted to the ICU, prolonged EDLOS was associated with major in-hospital complications.
