The prevalence of obesity is increasing at a disparaging rate in the United States. Although previous studies have associated obesity with increased surgical complications and readmission rates, the impact of obesity on surgical outcomes after cranial surgery remains understudied. The aim of this study is to assess the effect of obesity on complication and 30-day readmission rates after cranial surgery. ⋯ Our study suggests that obesity may not have a significant impact on surgical outcomes after cranial surgery.

Spinal cord herniation (SCH) is rare, is mostly idiopathic, and occurs predominantly in the thoracic spine. SCH is less common in the cervical spine and has been reported after posterior cervical spine surgery associated with the development of pseudomeningoceles. Two cases of SCH have been reported after anterior cervical corpectomies for ossified posterior longitudinal ligament with cerebrospinal fluid (CSF) leaks. We report the third such case, but the first in a patient without ossified posterior longitudinal ligament (degenerative disc disease and pseudarthrosis). ⋯ This is the first reported case of anterior cervical SCH in a patient without ossified posterior longitudinal ligament after multiple anterior cervical fusions including a cervical corpectomy for pseudarthrosis with a CSF leak. We hypothesize that persistent CSF leak causes a pressure gradient across the dura mater through the cage to the lower pressure in the retropharyngeal space, which led to herniation of the spinal cord into the anterior cage. We review the literature and discuss the treatment choices for anterior cervical SCH.

Posterior reversible encephalopathy syndrome (PRES) is characterized by headache, altered mental status, visual changes, and seizure combined with brain imaging consistent with cerebral edema without infarction. To the best of our knowledge, we report the first case of PRES after an endoscopic endonasal resection of a pituitary macroadenoma. ⋯ Although rare in neurosurgical patients, PRES must be considered in patients who develop acute vision loss and mental status changes associated with hypertension after surgery, including endoscopic endonasal surgery. PRES has the potential for significant neurologic morbidity, if not treated in a timely manner. Early recognition and treatment, with blood pressure control mainly, are therefore mandatory after a surgical complication, such as a postoperative hematoma, has been ruled out.

Sparing the hypothalamus after craniopharyngioma treatment is a prerequisite to ensure a good quality of life. In this study, the functional prognosis of craniopharyngioma after endoscopic endonasal skull base surgery (EES) was examined in function of the degree of hypothalamic extension. ⋯ EES provides optimal resection rate and limited complications because of the preservation of the hypothalamus, regardless of the degree of preoperative hypothalamic involvement. Consequently, the rate of obesity occurrence is also decreased. This study indicates that EES protects hypothalamus function and improves tumor removal rate, and that it will become the first choice of surgical procedure for managing craniopharyngiomas.

Treatment of pediatric hydrocephalus in sub-Saharan countries is associated with significant complication rates. The objective of this study is to analyze the management of hydrocephalus and complication rates of surgical intervention in the Ethiopian setting to improve future quality. ⋯ VP shunt insertions had unacceptably high infection rate despite the presence of a protocol for the procedure. Intraoperative guidelines should be developed further and followed strictly to reduce infections. Such measures should include restricting the number of surgeons performing the procedure. In our opinion, one should avoid insertion of a VP shunt as the primary treatment. ETV has proved to be a good alternative in other studies and the decreasing pattern of ETV failure in our study also suggest ETV as a better alternative to VP shunt.
