Review Meta Analysis
Intravenous Acetaminophen (Paracetamol) for Post-Craniotomy Pain; Systematic Review and Meta-analysis of Randomized Clinical Trials.
Acute pain control after supratentorial craniotomy is considered among the most important indicators of postoperative recovery. The aim of this study was to determine the effects of intravenous acetaminophen on postcraniotomy pain. ⋯ The results of this systematic review and meta-analysis indicate that preoperative intravenous administration of acetaminophen is associated with decreased postoperative pain, need for rescue analgesics, and dosages of analgesics after craniotomy surgery.

Ependymomas are common intramedullary spinal tumors but there are scattered reports of this tumor presenting with exophytic growth patterns masquerading as intradural extramedullary (IDEM) tumors. Such IDEM ependymomas are seldom suspected preoperatively and it is only during surgery that their existence is revealed. Little is known of such rare growth patterns of an otherwise common intramedullary spinal cord tumor, their characteristics, and their management considerations. ⋯ IDEM ependymomas are more common in thoracic segment of the cord and broadly divisible into 4 subgroups. We suggest a subpial origin of group II IDEM ependymomas. We also advocate proliferation index estimation in grade II ependymomas to enable formulation of an optimal management plan.

Genetic association studies about associations between angiotensin-converting enzyme (ACE) polymorphisms and intracranial hemorrhage (ICH) generated conflicting results. In this study, a meta-analysis was performed to better assess the relationship between ACE polymorphisms and ICH. ⋯ This meta-analysis suggests that ACE I/D polymorphism might affect individual susceptibility to ICH in both East Asians and South Asians. These results indicate that this polymorphism could be used to identify individuals at higher susceptibility to ICH in Asians.
