Glioblastoma (GBM) is both the most common and the most devastating primary cancer of the central nervous system, with an expected overall survival in most patients of about 14 months. Despite extensive research, outcomes for GBM have been largely unchanged since the introduction of temozolomide in 2005. We believe that in order to achieve a breakthrough in therapeutic management, we must begin to identify subtypes of GBM, and tailor treatment to best target a particular tumor's vulnerabilities. Our group has recently produced an examination of the clinical outcomes of radiation therapy directed at tumors that contact the subventricular zone (SVZ), the 3-5 mm lateral border of the lateral ventricles that contains the largest collection of neural stem cells in the adult brain...

Fixed-parameter algorithms are designed to efficiently find optimal solutions to some computationally hard (NP-hard) problems by identifying and exploiting "small" problem-specific parameters. We survey practical techniques to develop such algorithms. Each technique is introduced and supported by case studies of applications to biological problems, with additional pointers to experimental results.

BACKGROUND: Surgeries for lesions in the dominant hippocampal and parahippocampal gyrus involving the posteromedial temporal regions are challenging to perform because they are located close to Wernicke's area; white matter fibers related with language; the optic radiations; and critical neurovascular structures. We performed a transtemporal approach with awake functional mapping for lesions affecting the dominant posteromedial temporal regions. The aim of this study was to assess the feasibility, safety, and efficacy of awake craniotomy for these lesions...

Diagnosis of combined peripheral and central vestibulopathy remains a challenge since the findings from peripheral vestibular involvements may overshadow those from central vestibular disorders or vice versa. The aim of this study was to enhance detection of these intriguing disorders by characterizing the clinical features and underlying etiologies. We had recruited 55 patients with combined peripheral and central vestibulopathy at the Dizziness Clinic of Seoul National University Bundang Hospital from 2003 to 2013...

Wernicke's encephalopathy (WE) is a rare life-threatening complication following severe hyperemesis gravidarum. Early recognition of this condition and prompt thiamine administration is the key to preventing devastating sequelae. We report a successful delivery of a small-for-gestational-age (SGA) baby by a patient with WE and thyrotoxicosis in pregnancy.

A number of physiologic, hormonal, immunologic, and hemodynamic changes take place in the maternal body during pregnancy. The majority of these changes are essential for maintaining the normal course of pregnancy. However, these changes may also cause acute or chronic conditions that affect various biologic systems in the mother. In addition, conditions of the central and peripheral nervous systems can cause a variety of neurologic symptoms and complications. Neurologic signs and symptoms in pregnant and postpartum women may be due to the exacerbation of a preexisting medical condition, the initial manifestation of a primary central nervous system-related problem, or a neurologic problem unique to pregnancy and the postpartum period...

CONTEXT: Alcohol consumption has escalated rapidly in many countries over the past decade. Evidence suggests a correlation between alcohol use and cognitive decline. We have systematically reviewed the concept and controversies, epidemiology, nosology, neuropathology and neurobiology, neuropsychology and management updates of alcohol-related dementia (ARD) in this paper. EVIDENCE ACQUISITION: We retrieved papers for this review by searching the PubMed database for terms "alcohol and dementia", "alcohol and cognitive impairment", and "alcohol and wernicke-korsakoff" mentioned in the title of the published papers...

Thiamine deficiency (vitamin B1) is common in patients with alcohol dependence. Cognitive impairments may be an early consequence of thiamine deficiency. Wernicke's encephalopathy is underdiagnosed and undertreated. In patients with established Wernicke's encephalopathy, parenteral thiamine 200-500mg three times a day should be given for 3-5 days, followed by oral thiamine 250-1000mg/day. In patients with suspected Wernicke's encephalopathy, parenteral thiamine 250-300mg should be given two times a day for 3-5 days, followed by oral thiamine 250-300mg/day...

Inhibition of thiamine transporters has been proposed as a putative mechanism for the observation of Wernicke's encephalopathy and subsequent termination of clinical development of fedratinib, a Janus Kinase inhibitor (JAKi). This study aimed to determine the potential for other JAKi to inhibit thiamine transport using Caco-2 and thiamine transporter (THTR) over-expressing cells and to better elucidate the structural basis for interacting with THTR. Only JAKi containing a 2,4-diaminopyrimidine were observed to inhibit thiamine transporters...

Glioblastoma is not only the most common primary brain tumor, but also the most aggressive. Currently, the most effective treatment of surgery, chemotherapy and radiation therapy allows for a modest median survival of 15 months. Here, we report a case of a 57-year-old male with histologically confirmed glioblastoma with unfavorable prognostic characteristics (poor performance status and persistent neurological symptoms after surgery), whose expected 5-year survival is 0%. Further genetic analysis offered a mixed prognostic picture with positive methylation of 0-6-methylguinine-DNA (deoxyribonucleic acid) methyltransferase (MGMT; favorable prognosis) and wild-type isocitrate dehydrogenase 1 (IDH-1; unfavorable prognosis)...

BACKGROUND: Cesium-131 (Cs-131) brachytherapy is used to reduce local recurrence of resected brain metastases. In order to ensure dose homogeneity and reduce risk of radiation necrosis, inter-seed distance and cavity volume must remain stable during delivery. OBJECTIVE: To investigate the efficacy of the "seeds-on-a-string" technique with intracavitary fibrin glue in achieving cavity volume stability. METHODS: We placed intra-operative Cs-131 brachytherapy in 30 cavities post-resection of brain metastases...

Wernicke's encephalopathy is often undiagnosed, particularly in non-alcoholics. There are very few reports of non-alcoholic patients diagnosed with Korsakoff syndrome in the absence of a prior diagnosis of Wernicke's encephalopathy and no studies of diffusion tensor imaging in non-alcoholic Korsakoff syndrome. We report on three non-alcoholic psychiatric patients (all women) with long-term non-progressive memory impairment that developed after malnutrition accompanied by at least one of the three Wernicke's encephalopathy manifestations: ocular abnormalities, ataxia or unsteadiness, and an altered mental state or mild memory impairment...

Hyperemesis gravidarum-induced Wernicke's encephalopathy (WE) is an underestimated condition. The purpose of this study is to improve its awareness and early diagnosis. We report five cases of WE secondary to hyperemesis gravidarum. Classic triad of encephalopathy, ataxia, and ocular signs was seen in four out of five patients. Two unusual features noted in this series were papilledema in one patient and severe sensory-motor peripheral neuropathy in one patient. Magnetic resonance imaging (MRI) was abnormal in all the five patients, and high signal in medial thalamus and surrounding the aqueduct was the most common abnormality (5/5)...

In the sentence "The captain who the sailor greeted is tall," the connection between the relative pronoun and the object position of greeted represents a long-distance dependency (LDD), necessary for the interpretation of "the captain" as the individual being greeted. Whereas the lesion-based record shows preferential involvement of only the left inferior frontal (LIF) cortex, associated with Broca's aphasia, during real-time comprehension of LDDs, the neuroimaging record shows additional involvement of the left posterior superior temporal (LPST) and lower parietal cortices, which are associated with Wernicke's aphasia...
