Purpose : As a result of advances in neonatal intensive care and perinatal care, neurodevelopmental outcomes of very low birth weight infant(VLBWIS) is expected to lead to improvement. The aim of this study was to report neurodevelopmental outcomes and risk factors of neurologic impairment of very low birth weight infants during the past 10 years. Method : We performed a retrospective study of 447 newborn infants below 1,500 gm admitted to neonatal intensive care unit of Taegu Fatima Hospital between Janury 1996 and December 2004. Infants were subdivided into group 1(Jan. 1996 to Dec. 1998), group 2(Jan. 1999 to Dec. 2001), and group3(Jan. 2002 to Dec. 2004). We analyzed epidemiologic data to study changes of neurodevelopmental outcomes and risk factors of neurologic impairment. Result : The incidence of cerebral palsy and developmental delay decreased significantly in periods 2 and 3(vs period 1; cerebral palsy 10 percent, developmental delay; 18 percent, P<0.05). Periventricular leukomalacia incidence decreased in period 3(vs period 1; 14.5 percent, P<0.05). The overall survival rate of VLBWIS increased significantly in period 2 and 3(vs period 1; 90.0 percent, P<0.05). The risk factors of neurologic impairment are long-term ventilator care(above 1 wk), low Apgar score, low gestational age and low birth weight. Conclusion : In the most recent 10 years, neurologic impairments of VLBWIS significantly decreased, as a result of advances in neonatal intensive care and perinatal care.

Purpose : Brain metastases are the most frequent metastatic neurologic complication of systemic cancer. Even if the prognosis of brain metastases is grave, with available treatments, most patients experience effective palliation of neurologic symptoms and meaningful extension of life. We evaluated the clinical features and prognostic factors of the patients who were diagnosed as solid tumors with brain metastasis and received radiotherapy for brain metastases. Materials and Methods: Between January 1987 and January 1998, 71 patients with brain metastases from solid malignancy were included. We reviewed neurologic symptoms and signs of patients and evaluated improvememt of neurologic symptoms and signs. Survival durations after brain metastasis were ana lysed according to several factors such as age, performance status, primary malignancies, the pre-sence of brain metastasis at initial diagnosis of primary tumor, multiplicity of brain metastass, the presence of metastases other than brain, and treatment method. Results: Frequent symptoms associated with brain metastasis were headache (47.9$\%$), motor weakness (40.8$\%$), nausea and vomiting (19.7$\%$) and mental change (19.7%). Palliation of these symptoms was accomplished in 64.9$\%$ of cases. The overall median survival time was 16 weeks and 1- and 2-year survival rates were 15.0$\%$ and 5.1$\%$ respectively. Patients without extracranial metastases (n=27) had longer median survival than patients with extracranial metastases (33 weeks vs 10 weeks, p=0.0018). In patients with single brain metastasis (n=37), the median survival time was longer in patients treated with surgery plus radiotherapy than in patients treated with radiotherapy alone (40 weeks vs 16 weeks, p=0.0438). Conclusion: Patients who has brain metastases only constitute a prognostically favorable group and they may be benefited from radiotherapy and surgery if indicated.

Purpose: Human parechovirus (HPeV) is an increasingly recognized pathogenic cause of central nervous system (CNS) infection in neonates. However, HPeV infections have not been studied in older children. This study determined the prevalence and clinical features of HPeV CNS infection in children in Korea. Methods: Reverse transcription polymerase chain reaction assays were performed using HPeV-specific, 5' untranslated, region-targeted primers to detect HPeV in cerebrospinal fluid (CSF) samples from children presenting with fever or neurologic symptoms from January 1, 2013, to July 31, 2014. HPeV genotyping was performed by sequencing the viral protein 3/1 region. Clinical and laboratory data were retrospectively abstracted from medical records and compared with those of enterovirus (EV)-positive patients from the same period. Results: Of 102 CSF samples, six (5.9%) were positive for HPeV; two of 21 EV-positive samples were co-infected with HPeV. All samples were genotype HPeV3. Two HPeV-positive patients were <3 months of age and four others were over 1 year old. While HPeV-positive infants under 1 year of age presented with sepsis-like illness without definite neurologic abnormalities, HPeV-positive children over 1 year of age presented with fever and neurologic symptoms such as seizures, loss of consciousness, and gait disturbance. The CSF findings of HPeV-positive patients were mostly within the normal range, whereas most (73.7%) EV-positive patients had pleocytosis. Conclusions: Although HPeV is typically associated with disease in young infants, the results of this study suggest that HPeV is an emerging pathogen of CNS infection with neurologic symptoms in older childhood.

Object : This study was conducted as part of the national project to standardize stroke diagnosis in Korean medicine. In this study, we aimed to evaluate the characteristics of acute stroke between heat pattern group and cold pattern group. Methods : We recruited stroke patients from 5 universities(Kyung-Hee University oriental medical center, Kyung-Hee University East-West Neo medical center, Kyungwon university lncheon oriental medical center, Kyungwon university Songpa oriental medical center and DongGuk university llsan oriental medical center) from April, 2007 until February, 2010. We diagnosed them and selected 463 heat pattern patients and 182 cold pattern patients. Results : We find that the risk factor of smoking, alcohol, diet(prefer to meat) are more associated with the heat pattern group. On the other hand, inflammation history in recent 3 months and diet(prefer to sea food) are more associated with the cold pattern group. RBC, Hg, Hct, TG, CK and Cl are more related to the heat pattern group. CPT, total cholesterol and HDL are more related to the cold pattern group. Tae-eum type takes high distribution of the heat pattern group, and So-eum type takes high distribution of the cold pattern group. Conclusions : This study provides evidence that the heat pattern group have more risk factor than the cold pattern group.

Pulmonary aspergillosis is the most common disease of fungal infection and has lower infectivity. Pulmonary asergillosis is classified by aspergilloma, bronchopulmonary aspergillosis, necrotic and invasive aspergillosis. Invasive aspergillosis is found in immune compromised host, immunosuppressive treatment after organ transplantation, anticancerous chemotherapy, blood abnormality, AIDS patients etc. We reported a case of invasive aspergillosis in an immunocompetent host, with review of literatures.

The relationship between the brain monoamines and morphine tolerance was examined in ginseng total saponins treated mice. Ginseng total saponins (100 mg/kg, i.p.) did not antagonize morphine (10 mg/kg, s.c.) analgesia in mice. Daily treatment with ginseng total saponins (100 mg/kg) did not affect the brain levels of noradrenaline, dopamine and serotonin for 5 days but inhibited the development of morphine tolerance. This inhibition of the development of morphine tolerance was not attributed to the reductions of brain noradrenaline, dopamine and serotonin in mice treated with ginseng total saponins (100 mg/kg) daily. This result suggest that a newly equilibrated state of neurologic function may involve an underlying mechanism in mice treated with ginseng total saponins.

We present an extremely rare case of the atypical choroid plexus papilloma in an adult which developed at the trigone of right lateral ventricle. A 62-year-old woman presented with the history of intermittent and gradually progressive headache and left side hemiparesis for 6 months. The brain magnetic resonance image showed highly enhanced and well demarcated mass at the trigone of lateral ventricle attached to the choroid plexus. Gross total resection was performed by transcortical approach via the middle temporal gyrus. The tumor was diagnosed as an atypical choroid plexus papilloma. She had no neurologic deficit after the surgery. We report a case of atypical choroid plexus papilloma in adult and introduce newly classified pathologic characteristics of this tumor.

A 12-year-old spayed female Yorkshire terrier dog was presented with two-weeks history of lethargy, mental dullness and polydipsia. Neurologic examination revealed proprioceptive defect of all limbs and loss of swallowing gag reflex. The dog revealed persistent dehydration, hypernatremia, hyperosmolarity and hyposthenuria. On magnetic resornance imaging (MRI), the mass were heterogeneous signality on T1 weighted images, hyperintense signality on T2 weighted image with contrast enhancement on hypothalamohypophyseal lesion. Based on these findings, the dog was suspected as having pituitary gland tumor. Through water deprivation test and response to desmopressin acetate (1-deamino-8-D-arginine, DDAVP), this case was diagnosed by central diabetes insipidus (CDI). This paper reports the clinical sign, MRI, response to the exogenous antidiuretic hormone of CDI due to suspected pituitary tumor in a dog and DDAVP administration was evaluated effective therapy to correct hypernatremia induced by CDI.

Purpose. The main purpose of this critical ethnography was to examines the process and discourses through which family caregivers experience while caring for their sick family member in a hospital. Methods. This was achieved by conducting in-depth interviews with 12 family caregivers, and by observing their caring activities and daily lives in natural settings. The study field was a unit for neurologic patients. Data was analyzed using taxonomy, discourse analysis, and proxemics. All research work was iteratively processed from March 2003 to December 2004. Results. Constant comparative analysis of the data yielded the process of becoming a successful family caregiver: encountering the differences and chaos as novice; constructing their world of skilled caregivers; and becoming a hospital family as experienced caregivers. During the process of becoming an experienced hospital family, the discourse of family centered idea guided their caring behaviors and daily lives. Conclusion. The paternalistic family caregivers struggled, cooperated, and harmonized with the patriarchal world of professional health care system. During this process of becoming hospital family, professional nurses must act as cultural brokers between the lay family caring system and the professional caring system.

Low back pain is a common clinical condition with heterogeneous causes and challenges to manage. High prevalence and numerous assessments result in an enormous socioeconomic burden. Clinician must conduct efficient and stepwise evaluation process to rule out serious spinal pathology, neurologic involvement, and identify risk factors for chronicity. The process can be achieved through the focused history taking and physical examination. Certain factors related to serious spinal pathology include age (>50 years), trauma, unexplained fever, recent urinary or skin infection, unrelenting night or rest pain, unexplained weight loss, osteoporosis, immunosuppression, steroid use, and widespread neurological symptoms. In non-specific low back pain, diagnostic imaging and laboratory studies are often unnecessary and can disturb an appropriate management. For the management of acute low back pain, patient education and medication such as acetaminophen, non-steroidal anti-inflammatory drugs, and muscle relaxants are recommended. For chronic low back pain, behavior therapy, back exercise, and spinal manipulation are beneficial. The evidence based approach could improve success rate of management, result in prevention of acute low back pain from being chronic intractable pain.
