Review Meta Analysis
Antibiotic Impregnated External Ventricular Drains: Meta and Cost Analysis.
To determine whether antibiotic impregnated external ventricular drains (AI-EVDs) are effective in preventing ventriculostomy associated infection (VAI), and to examine their cost effectiveness. ⋯ Meta-analysis demonstrated a significant protective benefit of AI-EVDs against VAI, and this benefit is likely associated with cost savings. However, current data on AI-EVDs are limited, and overall hospital costs will vary among institutions. Although both the efficacy and cost effectiveness of AI-EVDs are supported by this analysis, further study of AI-EVDs is clearly warranted.

Review Case Reports
Managing a rare Malignant Sweat gland tumour invading the Brain: Case report and literature review.
Malignant sweat gland adnexal tumors are rare with an incidence of 0.001%. Of these, clear cell hidradenocarcinoma is an extremely uncommon subtype that accounts for 6% of malignant eccrine sweat gland tumors. They occur commonly in the head, neck, and extremities. Although they have a propensity for local recurrence, intracranial extension with brain invasion is extremely rare. ⋯ We report a rare indolent case of clear cell hidradenocarcinoma invading the brain, which was managed with near-total decompression and adjuvant radiotherapy. Intracranial extension in such aggressive tumors poses challenges in management, and regular neuroimaging surveillance is advised.

The three-dimensional (3D) endoscope is a novel tool that provides stereoscopic vision and may allow for improved dexterity and safety during surgical resection of ventral skull base lesions. We describe here the cumulative experience available in the neurosurgical literature. ⋯ Our findings suggest that 3D endoscopy provides improved surgical dexterity by affording the surgeon with depth perception when manipulating tissue and maneuvering the endoscope in the endonasal corridor.
