Comparative StudyCranial decompression for the treatment of malignant intracranial hypertension after ischemic cerebral infarction: decompressive craniectomy and hinge craniotomy.
Recent randomized trials have demonstrated a positive role (improved survival) in patients treated with cranial decompression for malignant cerebral infarction. However, many variables regarding operative decompression in this setting remain to be determined. Hinge craniotomy is an alternative to decompressive craniectomy, but its role in space-occupying cerebral infarctions has not been delineated. The objective of this study was to compare the authors' experiences with these 2 procedures in the management of space-occupying cerebral infarctions to determine the efficacy of each. ⋯ Hinge craniotomy appears to be at least as good as decompressive craniectomy in providing postoperative ICP control at a similar therapeutic index. Although the in-hospital mortality was higher in patients treated with hinge craniotomy, that procedure resulted in superior long-term functional outcomes and may help limit postoperative complications.

Case ReportsBilateral occlusion of the foramina of Monro after third ventriculostomy.
Occlusion of both foramina of Monro following third ventriculostomy is a very rare complication. The authors present the case of a 30-year-old female who underwent endoscopic third ventriculostomy (ETV) for occlusive hydrocephalus due to aqueductal stenosis. ⋯ Magnetic resonance imaging demonstrated bilateral enlargement of the lateral ventricles with a collapsed third ventricle caused by bilateral stenosis of the foramina of Monro. Left-sided endoscopic foraminoplasty and stenting of the left foramen of Monro were performed with immediate neurological improvement.

Delayed neuromotor recovery and increased memory acquisition dysfunction following experimental brain trauma in mice lacking the DNA repair gene XPA.
This study investigates the outcome after traumatic brain injury (TBI) in mice lacking the essential DNA repair gene xeroderma pigmentosum group A (XPA). As damage to DNA has been implicated in neuronal cell death in various models, the authors sought to elucidate whether the absence of an essential DNA repair factor would affect the outcome of TBI in an experimental setting. ⋯ The authors' results suggest that lack of the DNA repair factor XPA may delay neurobehavioral recovery after TBI, although they do not support the notion that this DNA repair deficiency results in increased cell or tissue death in the posttraumatic brain.

Elevated body mass index and risk of postoperative CSF leak following transsphenoidal surgery.
Postoperative CSF leakage can be a serious complication after a transsphenoidal surgical approach. An elevated body mass index (BMI) is a significant risk factor for spontaneous CSF leaks. However, there is no evidence correlating BMI with postoperative CSF leak after transsphenoidal surgery. The authors hypothesized that patients with elevated BMI would have a higher incidence of CSF leakage complications following transsphenoidal surgery. ⋯ Elevated BMI is an independent predictor of postoperative CSF leak after an endonasal endoscopic transsphenoidal approach. The authors recommend that patients with BMI greater than 30 kg/m(2) have meticulous sellar reconstruction at surgery and close monitoring postoperatively.
