Randomized Controlled Trial Multicenter Study Comparative Study
A Clinical Comparison of Anterior Cervical Plates versus Stand-Alone Intervertebral Fusion Devices for Single-Level Anterior Cervical Discectomy and Fusion Procedures.
To compare radiologic and clinical outcomes, including rates of dysphagia and dysphonia, using a no-profile stand-alone intervertebral spacer with integrated screw fixation versus an anterior cervical plate and spacer construct for single-level anterior cervical discectomy and fusion (ACDF) procedures. ⋯ Anterior cervical discectomy and fusion with stand-alone spacers resulted in similar clinical and radiologic outcomes as compared with plate and spacers and may help minimize postoperative dysphonia.

Anterior cervical discectomy (ACD) is one of the most common spinal surgeries. Although rare, iatrogenic vertebral artery injuries (VAIs) are potentially life-threatening. Risk factors are anatomic, operative, and pathologic. We report a rare case of iatrogenic VAI during ACD and successful endovascular treatment with no long-term complications. We also review the literature on all VAIs associated with ACD and fusions. Risk factors and the safety and effectiveness of various management modalities are discussed. ⋯ Delayed pseudoaneurysm formation after iatrogenic VAI can occur. Endovascular embolization can be a safe treatment alternative to surgical repair.

Review
Prevalence and incidence of drug-resistant mesial temporal lobe epilepsy in the United States.
We reviewed data on the epidemiology of epilepsy in the United States and estimated the prevalence and incidence of drug-resistant temporal lobe epilepsy (TLE) due to hippocampal sclerosis (HS) based on extrapolation from the available data drawn from the literature. ⋯ Although full scale epidemiologic studies on drug-resistant HS-TLE are needed, several observational studies allow adequate estimates of the range for the incidence and prevalence of this condition. Given the morbidity and mortality associated with poorly controlled seizures, this relatively large and growing patient population is a matter of concern. Considering the variety of treatment options that are available or in the pipeline to treat drug-resistant epilepsy, future efforts should focus on advocating for early referral of patients with drug-resistant HS-TLE for more comprehensive epilepsy management.

In Japan, neurosurgeons have traditionally mainly treated brain diseases, with most cases involving the spine and spinal diseases historically being treated by orthopedists. Nowadays, spinal surgery is 1 of the many subspecialties in the neurosurgical field in Japan. ⋯ Neurosurgeons in Japan must rethink the educational program to include advanced trauma life support and spinal surgery.

Despite selection process before awake-craniotomy, some patients experience an unexpected decline in language functions in the operating room (OR), compared with their baseline evaluation, which may impair their functional monitoring. To investigate this phenomenon we prospectively compared language function the day before surgery and on entrance to the OR. ⋯ Patients undergoing awake-craniotomy may experience a substantial decline in language functioning after entering the OR. Tumor grade and the presence of preoperative language deficits were significant risk factors for this phenomenon, suggesting a possible relation between cognitive reserve, psychobehavioral coping abilities and histologic features of a tumor involving language areas. Capturing and identifying this unique population of patients who are prone to experience such language decline may improve our ability in the future to select patients eligible for awake-craniotomy.
