: Isadore Max Tarlov (1905-1977) is primarily remembered for his 1938 description of the eponymous perineural "Tarlov cyst." However, during his long career as a neurosurgeon and researcher, he was responsible for many other observations and inventions that influenced the development of neurosurgery in the 20th century. While studying at Johns Hopkins Medical School he was acquainted with Walter Dandy, and he became the first resident to study under Wilder Penfield at the newly formed Montreal Neurological Institute...

BACKGROUND: The primary objective of this study was to characterize changes in cerebral blood flow measured using transcranial Doppler in children with central nervous system infections. We hypothesized that children with central nervous system infections have abnormal cerebral blood flow, associated with a greater frequency of complications and poor neurological outcome. METHODS: We conducted a single-center, retrospective study of children admitted to the neonatal or pediatric intensive care unit with central nervous system infection and undergoing transcranial Doppler as part of routine care between March 2011 and July 2015...

BACKGROUND: Conventional management for concussion involves prescribed rest and progressive return to activity. Recent evidence challenges this notion and suggests that active approaches may be effective for some patients. Previous concussion consensus statements provide limited guidance regarding active treatment. OBJECTIVE: To describe the current landscape of treatment for concussion and to provide summary agreements related to treatment to assist clinicians in the treatment of concussion...

Awake craniotomy for brain tumours  Awake neurosurgery is a useful method in lesions near eloquent brain areas, particularly low-grade gliomas.The aim is to maximise tumour resection and preserve neurological function. We performed 40 primary awake surgeries and 8 residual surgeries. Patients were operated awake throughout the procedure or with a laryngeal mask and general anaesthesia during the opening stage and then awake during intracerebral surgery. Language and motor function were mapped with direct cortical stimulation, motor evoked potential and standardised neurological testing...

INTRODUCTION: Parkinson's disease (PD) is a common neurodegenerative disease which begins in adulthood. Its incidence in Mexico is estimated to be 40-50 cases per 100,000 inhabitants/year and is the fourth reason for medical care in the National Institute of Neurology and Neurosurgery. The protein alpha-synuclein, SNCA, plays a key role in the pathology of PD, and its polymorphisms have been associated with an increased risk of developing the disease. AIM: To evaluate the risk of PD represented by the polymorphisms rs2619364, rs2619363, rs2736990, rs7684318, rs17016074, rs356219, rs356220 and rs356203 of SNCA in a sample of Mexican subjects...

Importance: Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disorder associated with the accumulation of infectious abnormal prion protein through a mechanism of templated misfolding. A recent report has described the detection of abnormal prion protein in the urine of patients with variant CJD (vCJD) using protein misfolding by cyclic amplification, which was apparently absent in the more common sporadic form of CJD (sCJD). A noninvasive diagnostic test could improve early diagnosis of sCJD and, by screening donations, mitigate the potential risks of prion transmission through human urine-derived pharmaceuticals...

PURPOSE: The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. METHODS: A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed...

OBJECTIVES: Surgical resection of low-grade gliomas (LGGs) in eloquent areas is one of the challenges in neurosurgery, using assistant tools to facilitate effective excision with minimal postoperative neurological deficits has been previously discussed (awake craniotomy and intraoperative cortical stimulation); however, these tools could have their own limitations thus implementation of a simple and effective technique that can guide to safe excision is needed in many situations. MATERIALS AND METHODS: The authors conducted a retrospective analysis of a prospectively collected data of 76 consecutive surgical cases of LGGs of these 21 cases were situated in eloquent areas...

Resection of large lesions growing into the third ventricle is considered nowadays still a demanding surgery, due to the high risk of severe endocrine and neurological complications. Some neurosurgical approaches were considered in the past the procedures of choice to access the third ventricle, however they were burden by endocrine and neurological consequences, like memory loss and epilepsy. We report here the endocrine and functional results in a series of patients operated with a recently developed approach specifically tailored for the resection of large lesions growing into the third ventricle...

BACKGROUND: Tumors with epicenter in the thalamus occur in about 4 % of pediatric brain tumors. The histological diagnosis is mainly gliomas. Among them, low-grade glioma (LGG) constituted of a significant entity of the tumors (Cuccia et al., Childs Nerv Syst 13:514-521, 1997; Puget et al., J Neurosurg 106:354-362, 2007; Bernstein et al., J Neurosurg 61:649-656, 1984; Bilginer et al., Childs Nerv Syst 30:1493-1498, 2014). Since Kelly's report in 1989, >90 % resection of thalamic tumors were achieved in reported series (Ozek and Ture, Childs Nerv Syst 18:450-6, 2002; Villarejo et al...

China is currently the most populous and rapidly aging nation in the world. In the next few decades, China will have to increase the throughput, quality, and scope of its neurosurgical training programs in order to meet forecasted demand. Until recently, China lacked national education standards in neurosurgery that fostered imbalances in medical and pedagogical resources, quality of care, and education between different regions; and introduced significant heterogeneity in neurosurgical competency. In 2010, Shanghai implemented the first new standards-based comprehensive neurosurgery training program, which spans 7 years broken down into 2 blocks...
