Normal-pressure hydrocephalus (NPH) is a disease characterized by gait disturbance, urinary incontinence, and dementia. Our objectives were to define an average value of the test for the population, check the specificity and test sensitivity as evaluation criteria and diagnostic testing, and correlate with other already used more frequently. ⋯ TUG is a good test for the diagnosis of NPH because there is very good specificity and sensitivity, with a mean value of 16.5 seconds as the cut-off.

Percutaneous dilatational tracheostomy (PDT) is a commonly performed method in neurocritical care, and its safety has been proven in numerous studies. Nevertheless, data regarding the application in patients with acute brain injury and poor respiratory function are poor. The purpose of this study was to evaluate the incidence of hypoxemia and hypercapnia during PDT in those patients. ⋯ Regarding the intraoperative gas exchange, indication of PDT in patients with ABI and ARDS should be considered carefully. However, PDT in ABI patients with reduced PaO2/FiO2 ratio alone appears to be a safe procedure.

Review Case Reports
Spontaneous regression of a hypoglossal neurinoma: a case report and review of the literature.
Hypoglossal neurinomas are very rare intracranial tumors. The management choices include surgery, as the gold standard, and radiosurgery or a combination of both. Little is known about this condition and the behavior of this tumor. ⋯ Our case highlights the importance of considering careful observation and diligent follow-up as a treatment option, as these lesions can show spontaneous regression with no invasive approaches.

Case Reports
Internal Maxillary Artery Bypass with Radial Artery Graft Treatment of Giant Intracranial Aneurysms.
Giant intracranial aneurysms (GIAs) can be approached via microsurgical and endovascular techniques. Use of flow diversion devices has yielded favorable outcomes, and indications for cerebral revascularization have dramatically decreased. ⋯ Considering the grave natural history and treatment complexity of these lesions, this study showed satisfactory results in the treatment of GIAs with IMA bypass.
