Cerebrospinal fluid (CSF) leaks usually happen in the early postoperative period. However, delayed CSF leak can happen several years after treatment. The purpose of this study was to review the characteristics and clinical course of delayed CSF leak after treating skull base tumors. ⋯ Patients with delayed CSF leak are more likely to have a history of radiation and to present with meningitis at diagnosis. Therefore, CSF rhinorrhea should always be suspected, even several years after treatment, if early symptoms of CSF leak develop in patients with a history of skull base tumor.

Chronic subdural hematoma (CSDH) is a common form of intracranial hemorrhage with a substantial recurrence rate. We aimed to investigate the predictive factors for the postsurgical recurrence of CSDH. ⋯ Burr hole craniostomy with irrigation and closed-system drainage is effective for the surgical treatment of CSDH. Mixed density hematoma is an independent predictor for the recurrence of CSDH. Presence of thick inner neomembrane might be the primary cause of CSDH recurrence.

Despite improved medical management, the incidence of spinal pathology remains high in patients with Parkinson disease (PD). Several studies have investigated lumbar spine surgery in this population, but data regarding costs and perioperative complications for patients undergoing cervical decompression/fusion on a nationwide scale are lacking. ⋯ Although patients with PD experience greater complication rates and non-home discharges following cervical spine surgery compared with NPD patients, the overall clinical impact of these results may be minimal relative to surgery at other spinal levels in this population.

Glioma is the most frequent primary brain tumor. Immunotherapy is one of the most promising therapeutic approaches for gliomas. T cell immunoglobulin domain and mucin domain-3 can induce the malignancy of gliomas. The function of galectin-9 (GAL-9), as one of the ligands of T cell immunoglobulin domain and mucin domain-3, in glioma has remained elusive. The aim of this study was to characterize the expression of GAL-9 in patients with glioma. ⋯ Our results highlight the pivotal role of GAL-9 in regulation of immune suppressive features of gliomas and indicate that GAL-9 is a promising target for cancer immunotherapy and may lead to development of further therapies.

Hydrocephalus is the most common complication of extraparenchymal neurocysticercosis, combining obstructive and inflammatory mechanisms that impair cerebrospinal fluid circulation. ⋯ Our neurocysticercosis-induced hydrocephalus model allows for the long-term maintenance of hydrocephalic animals, involving mild clinical performance impairments, including body weight and behavioral changes.
