Initial experience in the microsurgical treatment of ruptured brain aneurysms in the endovascular era: characteristics and safety of the learning curve in the first 300 consecutively treated patients.

Purpose: Currently, there is an increasing tendency to refer only complex aneurysms for microsurgery. The formation of new neurosurgeons dedicated to open vascular neurosurgery becomes challenging in a situation in which complex aneurysms must be dealt with early in the career, raising questions about the safety of the learning curve.

Methods: We analyzed the characteristics and surgical results of the first 300 consecutively treated patients after subarachnoid hemorrhage by a single neurosurgeon.

Lateral supracerebellar infratentorial approach for a ruptured cerebellomesencephalic fissure arteriovenous malformation resection.

In this surgical video, the authors present a case of a 24-year-old male patient who presented with sudden-onset headache and imbalance. On examination, he had a right-sided dysmetria and was otherwise neurologically intact. MRI showed a right cerebellar hematoma associated with multiple flow voids in the cerebellomesencephalic fissure and an enlarged lateral mesencephalic vein.

Cognitive Dysfunction and Single Nucleotide Polymorphisms in Hepatitis C Virus-Infected Persons: A Systematic Review.

The aim of this study was to realize a systematic review to identify data reported in the literature involving people infected by hepatitis C virus (HCV) with cognitive dysfunctions and single nucleotide polymorphisms (SNPs). The research was realized in six databases and the selection of studies was performed in two stages. Initially, we searched indexed articles from the following electronic databases: SciELO, MEDLINE, PubMed, HighWire, LILACS, and ScienceDirect.
