[IS ROUTINE CT SCAN NECESSARY AFTER THE REMOVAL OF BENIGN BRAIN TUMORS?].

Aims: Determine if early CT evaluation is justified in patients operated on for benign brain tumors.

Background: Researchers have recently questioned the common practice of referring all patients after cranial surgery for CT scans to rule out silent complications.

Methods: The cohort included 257 consecutive patients who underwent surgical removal of a benign brain tumor in the years 2011-2016.

Relative neuroprotective effects hyperbaric oxygen treatment and TLR4 knockout in a mouse model of temporary middle cerebral artery occlusion.

Purpose: To examine the effects of hyperbaric oxygen (HBO) therapy and knockout of toll-like receptor 4 (TLR4) on the outcome of temporary middle cerebral artery occlusion (MCAO) in a mouse model.

Materials And Methods: MCAO was induced in anesthetized male C57Bl/6 mice (WT) and TLR4 knockout mice (TLR4(-/-)) using an intra-arterial filament method. After 30 or 90 min, the filament was removed, and the mice were given either no treatment (WT and TLR4(-/-) groups) or HBO (WT only).
