Background: Glioblastoma is the most aggressive primary brain tumor in adults. The prognosis is still very poor with a median survival time less than a year. A growing body of data supports the role for fatty acid oxidation (FAO) in the aggressive behavior of glioblastoma.

Purpose: Currently available grading and classification systems for hemifacial spasm either rely on subjective assessments or are excessively intricate. Here, we make use of facial recognition and facial tracking technologies towards accurately grouping patients according to severity and characteristics of the spasms.

Methods: A retrospective review of our prospectively maintained preoperative videos database for hemifacial spasm was done.

Background: Colloid cysts (CCs) are benign lesions commonly located in the third ventricle, near the foramen of Monro. They constitute about 0.5%-1% of all intracranial tumors.

Background And Objectives: Despite a 90% success rate, microvascular decompression occasionally fails to resolve hemifacial spasm (HFS), necessitating revision surgery. We investigated recurrent cases to identify underlying causes.

Methods: We evaluated patients at our institution who underwent revision microvascular decompression because of recurrent or persistent HFS, assessing recurrence causes, decompression techniques, complications, and outcomes.

Article Synopsis
  • About 20-40% of melanoma patients develop brain metastases, which makes treatment really hard.
  • Researchers studied the genes and markers in these brain tumors to find new ways to help patients.
  • They discovered that a certain protein called MET might help the tumors grow and avoid treatment, so targeting MET could be a good way to control these brain tumors.

Background: Eosinophilic granuloma (EG) belongs to the family of Langerhans cell histiocytosis (LCH) and is considered to be a benign disease typically found in children younger than 15 years of age. Here, the authors describe an EG of unusual localization and clinical presentation.

Observations: The authors report a 9-year-old girl with an EG presenting as an osteolytic lesion of the clivus.

Study Design: Prospective quasi-experimental observational study.

Objective: The objective of this study was to evaluate whether duration of surgery is a modifiable risk factor for postoperative delirium (POD) after spine surgery and explore further modifiable risk factors. In addition, we sought to investigate the association between POD and postoperative cognitive dysfunction and persistent neurocognitive disorders.

The α-secretase A disintegrin and metalloprotease 10 (ADAM10) regulates various physiological and pathophysiological processes. Despite its broad functional implications during development, plasticity, and disease, no pharmacological approaches to inhibit ADAM10 in acute brain injury have been reported. Here, we examined the effects of the ADAM10 inhibitor GI254023X on the neurological and histopathological outcome after experimental traumatic brain injury (TBI).

Background: Instrumentation of the lumbosacral region is one of the more challenging regions due to the complex anatomical structures and biomechanical forces. Screw insertion can be done both navigated and based on X-ray verification. In this study, we demonstrate a fast and reliable open, low exposure X-ray-guided technique of iliac screw placement.

Purpose: Disialoganglioside GD is expressed by glioblastoma multiforme (GBM) cells representing a promising target for anti-GD2 immunotherapeutic approaches. The aim of the present study was to investigate anti-tumor efficacy of the chimeric anti-GD antibody (Ab) dinutuximab beta against GBM.

Methods: Expression levels of GD2 and complement regulatory proteins (CRP; CD46, CD55 and CD59) on well-known and newly established primary tumor originated GBM cell lines were analyzed by flow cytometry.
