  • The aim of this work is to develop 3-D stereotactic localization system in order to determine the precise shape, size and location of the lesion in the brain in the field of Stereotactic Radiosurgery(SRS) and neurosurgery using CT/MRI/angiography and multi-purpose QA phantom. The algorithms to obtain a 3-D stereotactic coordinates of the target have been developed, and targets on each CT image were superimposed each other on MR/angiography images without distortion corretion. This system was implented in Visual C++ as a PC-based application program.

  • Cerebral palsy refers to the neuromuscular deficit caused by nonprogressive defect or lesion in single or multiple locations in the immature brain resulting in Impaired motor function and sensory integrity. The pathophysiological events may occur during the prenatal intrapartum, perinatal, or early postnatal period. Cerebral palsy is the most common condition and it poses a challenge to practitioners due to the large variation in prognosis for motor function of children with this diagnosis. The objectives of this article are review to pathological and psychological factors of cerebral palsy and upper extremity function. Upper extremity and hand function are most important in activity of daily living in cerebral palsy This article hope to give the information for application in many therapists.

  • Gaucher disease is a multisystemic disorder arising from a deficient activity of the lysosomal enzyme glucocerebrosidase, which leads to accumulation of glycosylceraide and other glycolipids in the regiculoendothelial system. The characteristics of Gaucher disease are anemia, thrombocytopenia, hepatosplenomegaly, and skeletal disease. Enzyme replacement therapy (ERT) has been proven to prevent progressive manifestations of Gaucher disease and effective in improving anemia, thrombocytopenia, bone markers and biomarkers. However, some patient needs still remain unmet because of the inaccessibility of certain sites including brain, bone and various organs. ERT could not Improve the irreversible lesion such as liver fibrosis, hepatopulmonary syndrome, and necrosis or infarction of bone and other organs. Adult patients with Gaucher disease should be screened for longterm complication such as bone disease, pulmonary hypertension, gallstone, and cancer, especially in patients with splenectomy. Parkinsonism and polyneuropathy was also reported among patients with type 1 Gaucher disease, but ERT does not improve neurological function. We need to review the benefits and unmet needs of ERT in Gaucher disease.

  • Isolated hypoglossal nerve paresis due to mechanical compression from a vascular lesion is very rare. We present a case of a 32-year-old man who presented with spontaneous abrupt-onset dysarthria, swallowing difficulty and left-sided tongue atrophy. Brain computed tomographic angiography and magnetic resonance imaging of the brainstem demonstrated an abnormal course of the left vertebral artery compressing the medulla oblongata at the exit zone of the hypoglossal rootlets that was relieved by microvascular decompression of the offending intracranial vertebral artery. This case supports the hypothesis that hypoglossal nerve palsy can be due to nerve stretching and compression by a pulsating normal vertebral artery. Microvascular decompression of the intracranial nerve and careful evaluation of the imaging studies can resolve unexpected isolated hypoglossal nerve palsy.

  • Osteolipoma is an ossified lipoma with distinct components of fat and bone. We present a case of interhemispheric osteolipoma associated with total agenesis of the corpus callosum. A 20-year-old man complained of severe headache, nausea and vomiting. Brain computed tomography showed a low-density mass in an interhemispheric fissure, with high T1 and T2 magnetic resonance signals compatible with fat. The mass measured $4.9\;{\times}\;2.9\;cm$ in size and showed peripheral calcifications. There was another small piece of same signal mass within the lateral ventricular choroid plexus. The interhemispheric lesion was removed by an interhemispheric approach. Osteolipoma is rare in interhemispheric region, however, it should be a differential diagnosis of lesions with fat intensity mass and calcifications.

  • Klippel-Trenaunay syndrome (KTS) is a rare congenital malformation syndrome involving blood and lymph vessels, which is characterized by triad of cutaneous hemangioma, venous varicosities, and overgrowth of the affected limbs. Because vascular malformation in KTS can be located anywhere except the face and brain, the clinical presentation could be extremely variable. But there are only rare case reports that KTS is associated with spinal cord lesion. We report a case of recurrent myelopathy in a patient with KTS.

  • Hemiplegia cruciata (HC) manifests as paralysis of the ipsilateral arm and contralateral leg. Herein, we report a 64-year-old man with weakness of the right leg and of the left arm after multiple sclerosis (MS). His brain and spine magnetic resonance imaging show a lower medulla lesion, which is extended to posterior part of C1 spine through cervicomedullary junction. HC usually results from stroke or trauma, but it is rare as presenting symptom of MS.

  • Microglia are the primary resident immune cells of the central nervous system (CNS). They are the first line of defense of the brain's innate immune response against infection, injury, and diseases. Microglia respond to extracellular signals and engulf unwanted neuronal debris by phagocytosis, thereby maintaining normal cellular homeostasis in the CNS. Pathological stimuli such as neuronal injury induce transformation and activation of resting microglia with ramified morphology into a motile amoeboid form and activated microglia chemotax toward lesion site. This review outlines the current research on microglial activation and chemotaxis.

  • The recruitment and infiltration of monocytes into the artery wall is a crucial early step in atherogenesis. KR-31378 has been shown to be a neuroprotective agent in rat brain via its potent antioxidant and antiapoptotic actions. Here, we report the effects of this compound on atherogenesis, and some possible mechanisms of action.(omitted)

  • Rosai-Dorfman Disease[RDD] is an idiopathic histiocytic proliferation affecting lymph nodes. Although extranodal involvement has been reported in the skin, orbit, upper respiratory tract, of testes, the isolated intracranical involvement without associated lymphadenopathy is extremely rare. We report our experience with 1 case of an isolated intracranial RDD without associated lymphadenopathy and any other organ involvement. A 61-year-old male presented with an isolated well-circumscribed brain mass in the posterior fossa, preoperatively thought to be a meningioma. But histology and Immunohistochemistry confirmed that the lesion was RDD.
