Neuroprotective Effects of Thymoquinone on The Hippocampus in A Rat Model of Traumatic Brain Injury.
Traumatic brain injury is a leading cause of morbidity and mortality worldwide. We evaluated the neuroprotective effects of thymoquinone (TQ) in a rat model of traumatic brain injury by using biochemical and histopathologic methods for the first time. ⋯ These results indicate that TQ has a healing effect on neural cells after head injury and this effect is mediated by decreasing MDA levels in the nuclei and mitochondrial membrane of neurons.

Chronic subdural hematomas (CSDHs) are common neurosurgical conditions among elderly patients. ⋯ This comprehensive, best evidence-based, quantitative, systematic review indicates that the use of a closed system drainage after burr-hole evacuation reduces the rate of recurrences but has no other significant differences. The findings also suggest that: (1) treatment with twist drills is equivalent to that with burr holes; (2) the postoperative bed header in the elevated position might reduce the length of hospital stay; (3) irrigation of the subdural space with thrombin solution in patients with high risk of recurrence might reduce this risk; and (4) treatment with twist drill followed by a closed system drainage during 48 hours, instead of 96 hours, might reduce general complication rates. Most of the trials suffered from unclear or high risks of bias and many involved small samples, precluding strong and definitive conclusions.

Predictors of Shunt-Dependent Hydrocephalus Following Aneurysmal Subarachnoid Hemorrhage.
Shunt-dependent hydrocephalus is a common complication of aneurysmal subarachnoid hemorrhage (aSAH). There is a need to identify patients who require ventriculoperitoneal shunt (VPS) insertion so that any modifiable risk factors can be addressed early after aSAH. ⋯ The presence of an external ventricular drain and increased daily CSF output (above 78 mL/day) seems to be predictive of subsequent VPS insertion after aSAH. Although we could not identify modifiable risk factors for needing a VPS, nevertheless, these findings identify patients at greatest risk of VPS placement and inform treatment decisions as well as patient expectations.
