Intracranial clear cell meningioma: Clinical study with long-term follow-up in 24 patients.
Clear cell meningioma (CCM) is a rare disease, and controversy about treatment and prognosis of CCMs still exists. We aimed to clarify the natural history, radiological features, histological characteristics, management and prognosis of intracranial CCMs. ⋯ CCMs are rare diseases which have a predilection to affect younger patients and a high rate of recurrence and metastasis. Surgery resection is the first treatment choice. For patients underwent STR or with MIB-1 index ≥3%, we hold further radiotherapy is necessary. Close follow-up of the brain and spine for years is crucial to monitor recurrence or metastasis.

Anticoagulant prophylaxis against venous thromboembolism following severe traumatic brain injury: A prospective observational study and systematic review of the literature.
Venous thromboembolism (VTE) is a serious complication following severe traumatic brain injury (TBI), however, anticoagulant prophylaxis remains controversial due to concerns of intracranial hemorrhage (ICH) progression. We examined anticoagulant prophylaxis practice patterns at a major trauma centre and determined risk estimates for VTE and ICH progression classified by timing of anticoagulant initiation. ⋯ VTE is a common complication after severe TBI. Anticoagulant prophylaxis is often started late (≥3d) post-injury. Randomized trials are justifiable and necessary to provide practice guidance with regards to optimal timing of anticoagulant prophylaxis.

Diffuse low grade glioma after the 2016 WHO update, seizure characteristics, imaging correlates and outcomes.
The majority of patients with supratentorial diffuse grade II glioma present with seizures, which adversely affect quality of life. The exact mechanism of epileptogenesis is unknown and the influence of tumour characteristics, radiological and histological, are not well studied, particularly following the introduction of molecular genetics in the 2016 WHO reclassification of gliomas. We sought to define predictors of seizure development and outcome in low grade glioma. ⋯ Seizure outcome is directly related to EOR in low grade glioma, which can be predicted by the initial tumour volume. Tumour histological subtype, including updated molecular genetic classification did not predict seizure development or outcome in this series. The use of awake craniotomy results in greater EOR and improved Engel Class following surgery.

Relationship between the location of the ventricular catheter tip and the ventriculoperitoneal shunt malfunction.
Ventriculoperitoneal (VP) shunt is the most common neurosurgical procedure to treat obstructive and communicating hydrocephalus, but failures are frequent. The most common causes of shunt failure are malpositioning and obstruction of the ventricular catheter by debris or blood clothes. The knowledge of the relationship between ventricular catheter tip position, etiology of hydrocephalus and patient's age with shunt malfunction may be useful to avoid shunt failure. ⋯ Ventricular catheter tip position is one the most important factor for shunt function.
