Adult-onset epilepsy and risk of traumatic brain injury: a nationwide cohort study.
A knowledge gap exists regarding the risk of traumatic brain injury (TBI) in patients with epilepsy. ⋯ Patients with adult-onset epilepsy have a significantly increased risk of severe and fatal TBI. The results underline the importance of TBI prevention in epilepsy.

Observational StudyAcute Effects of Ketamine on Intracranial Pressure in Children With Severe Traumatic Brain Injury.
The acute cerebral physiologic effects of ketamine in children have been incompletely described. We assessed the acute effects of ketamine on intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in children with severe traumatic brain injury (TBI). ⋯ In this retrospective, exploratory study, ICP did not increase following ketamine administration. In the setting of a guidelines-based protocol, ketamine was associated with a reduction in ICP during ICP crises. If these findings are reproduced in a larger study, ketamine may warrant consideration as a treatment for intracranial hypertension in children with severe TBI.

We report results of a newly developed portable near-infrared spectroscopy (NIRS) based point-of-care device CEREBO® to detect traumatic intracranial hematoma (TICH). ⋯ The performance of currently tested NIRS device for detection of TICH was good and can be considered for triaging a patient requiring a CT scan of the head after injury. The NIRS device can efficiently detect traumatic unilateral hematomas as well as those bilateral hematomas where the volumetric difference is greater than 2cc.

Decompressive hemicraniectomy (DHC) is performed to relieve life-threatening intracranial pressure elevations. After swelling abates, a cranioplasty is performed for mechanical integrity and cosmesis. Cranioplasty is costly with high complication rates. Prior attempts to obviate second-stage cranioplasty have been unsuccessful. The Adjustable Cranial Plate (ACP) is designed for implantation during DHC to afford maximal volumetric expansion with later repositioning without requiring a second major operation. ⋯ ACP implantation during DHC is technically feasible. It achieves a volume of cranial expansion that will accommodate that observed following survivable hemicraniectomy operations. Moving the implant from the up to the down position can easily be performed as a simple outpatient or inpatient bedside procedure, thus potentially eliminating second-stage cranioplasty procedures.

Amazonas is the largest state in Brazil, covering an area of 1,559,159.148 km2 and primarily occupied by the Amazon rainforest. Fluvial and aerial transport are the primary means of transportation. Studying the epidemiologic profile of patients transported by neurologic emergencies is essential because there is only 1 referral center hospital serving approximately 4 million inhabitants in Amazonas. ⋯ Air transportation for neurologic evaluation is essential in Amazonas. However, most patients did not require neurosurgical intervention, indicating that investments in medical infrastructures, such as computed tomography scanners and telemedicine, may optimize health costs.
