Development of novel therapies for CNS tumors requires reliable assessment of response and progression. This requirement has been particularly challenging in neuro-oncology for which contrast enhancement serves as an imperfect surrogate for tumor volume and is influenced by agents that affect vascular permeability, such as antiangiogenic therapies. In addition, most tumors have a nonenhancing component that can be difficult to accurately quantify. To improve the response assessment in neuro-oncology and to standardize the criteria that are used for different CNS tumors, the Response Assessment in Neuro-Oncology (RANO) working group was established...

Gliomas are the most common CNS tumors in children and adolescents, and they show an extremely broad range of clinical behavior. The majority of pediatric gliomas present as benign, slow-growing lesions classified as grade I or II by the WHO classification of CNS tumors. These pediatric low-grade gliomas (LGGs) are fundamentally different from IDH-mutant LGGs occurring in adults, because they rarely undergo malignant transformation and show excellent overall survival under current treatment strategies. However, a significant fraction of gliomas develop over a short period of time and progress rapidly and are therefore classified as WHO grade III or IV high-grade gliomas (HGGs)...

Suspected cauda equina syndrome (CES) requires urgent evaluation, investigation and treatment. Timing of cauda equina decompression is crucial, and delays in its management, leading to significant irreversible disability can be devastating for patient and surgeon alike. The standard of care in CES therefore needs to be clear and unambiguous. Todd and Dickson have written an excellent paper summarising the condition, and have outlined what they feel is the standard of care. We would ask the authors to clarify an important point...

BACKGROUND: There exists a need for effective and easy-to-use software tools supporting the analysis of complex Electrocorticography (ECoG) data. Understanding how epileptic seizures develop or identifying diagnostic indicators for neurological diseases require the in-depth analysis of neural activity data from ECoG. Such data is multi-scale and is of high spatio-temporal resolution. Comprehensive analysis of this data should be supported by interactive visual analysis methods that allow a scientist to understand functional patterns at varying levels of granularity and comprehend its time-varying behavior...

BACKGROUND: Although half of all medical students are now and women are increasingly filling surgical residency positions, few ascend the academic ladder to become chairman of their departments, much less full academic professors. METHODS: We queried PubMed to search for the number of women surgeons in different subspecialties, and asked how many were chairman or full academic professors? RESULTS: Data coming out of largely general or cardiothoracic surgery departments cited no substantial gains for women surgeons over the years; there were few chairmanships or full professorships...

BACKGROUND: Currarino syndrome (CS) is a rare genetic condition that presents with the defining triad of anorectal malformations, sacral bone deformations, and presacral masses, which may include teratoma. Neurosurgeons are involved in the surgical treatment of anterior meningoceles, which are often associated with this condition. The accepted surgical treatment is a staged anterior-posterior resection of the presacral mass and obliteration of the anterior meningocele. CASE DESCRIPTION: This case involved a 36-year-old female who presented with late onset of symptoms attributed to CS (e...

Cho Ray Hospital is the premier tertiary care center in Ho Chi Minh City, Vietnam's most populous city. The neurosurgical department was founded in 1958 and is currently one of the busiest in the world. Last year the department was responsible for over 10,000 neurosurgical operations, excluding neuroendovascular cases. Most of the elective cases are craniotomies for complex lesions such as aneurysms, AMV's, skull base tumors, gliomas and meningiomas. While the neurosurgeons within the department are technically gifted, doing more with less predominates as the mantra at Cho Ray Hospital...
