Background Many specialty societies have found that neuroimaging in headache is a low-value intervention for benign presentations. This study describes factors that influence Emergency Room (ER) physicians' adherence to Choosing Wisely (CW) recommendations for low-risk headache patients presenting to Calgary's Emergency Departments (EDs). Emergency medicine has yet to address imaging in headache as a CW topic; however, this study may inform that decision. Methods Data were retrospectively collected for all patients presenting to Calgary EDs with headaches from April 1, 2014 to March 31, 2016...

OBJECTIVE The authors report a novel paradigm for resection of the disc or dural complex to treat giant calcified transdural herniated thoracic discs, and they describe a technique for the repair of dural defects. These herniated thoracic discs are uncommon, complicated lesions that often require a multidisciplinary team for effective treatment. The intradural component must be removed to effectively decompress the spinal cord. The opening of the friable dura mater, which frequently adheres to the extradural component of the disc, can result in large defects and difficult-to-manage CSF leaks...

The 2016 scientific meeting of the American Association of Neurological Surgeons (AANS) focused on the theme "A World of Innovation." In his presidential address, 2016 AANS President Frederick Boop compared the historical development of the specialty of neurological surgery with that of the development of global communications. In the early years, general surgeons training in the United States would spend post-residency time abroad learning from surgical masters in Europe and other places. Since Harvey Cushing's day, neurosurgeons from around the world continue to travel abroad, with many now coming to America for training at centers of excellence...

BACKGROUND: In previous studies of pneumococcal meningitis in adults within general hospitals or national cohorts, the most common predisposing conditions are otitis media, sinusitis, pneumonia, immunosuppression, alcoholism, and diabetes. The epidemiology of pneumococcal meningitis is changing due to the use of vaccines in childhood, and antibiotic resistance has increased. METHODS: We retrospectively reviewed the cases of patients with diagnosis of pneumococcal meningitis proved by an inflammatory CSF with a positive culture, treated during a period of 14 years at an adult neurosurgical neurological reference center...

Neuroscience began with neuroanatomy and neurosurgery in Egypt more than 5000 years ago. Knowledge grew over time and specialized neurosurgery centers were established in north Africa in the eleventh century. However, it was not until the twentieth century that neuroscience research became established in sub-Saharan Africa. In most African countries, clinical research focused on understanding the rationale and improving treatment of epilepsy, infections, nutritional neuropathies, stroke and tumors. Significant advances were made...

The modified frailty index (mFI) is emerging as a leading measure for preoperative risk assessment using routinely available medical record data. Our objective was to determine if mFI predicts morbidity and mortality in the diverse national cohort of patients undergoing neurosurgery for intracranial neoplasms. We identified patients in the National Surgical Quality Improvement Program who underwent oncologic neurosurgery procedures between 2008 and 2012. The mFI, ranging from 0 to 1, was calculated as the proportion of 11 possible risk factors present...

Brit Long, Alex Koyfman
Neurotrauma is a leading cause of death and is associated with many secondary injuries. A balance of mean arterial pressure (MAP) and intracranial pressure (ICP) is required to ensure adequate cerebral blood flow and cerebral perfusion pressure. Evaluation and management in the emergency department entails initial stabilization and resuscitation while assessing neurologic status. ICP management follows a tiered approach. Intubation requires consideration of preoxygenation, head of bed elevation, first pass success, and adequate analgesia and sedation...

BACKGROUND: Cranioplasty is considered a low-risk operation in the field of neurosurgery following decompression craniectomy (DC). Well-known complications after cranioplasty, such as infection, seizure, and titanium plate exposure, may not threaten the lives of patients. Unfortunately, there are many fatal complications that are under reported. In this study, we report a case and perform a literature review to introduce malignant cerebral swelling, which is regarded as a devastating complication...

We report a case of free flap deterioration which may have been induced by pressure gradient resulting from cranial defect overlying a ventriculoperitoneal shunt (VP shunt). The patient, male and aged 78, had a VP shunt operation for progressive hydrocephalus. Afterwards, the scalp skin flap surrounding the VP shunt collapsed and showed signs of necrosis, exposing part of the shunt catheter. After covering the defect with a radial forearm free flap, the free flap site showed signs of gradual sinking while the vascularity of the flap remained unimpaired...

Antiepileptic drugs (AEDs) possess diverse mechanisms of action - enhancement of GABA-mediated events, inhibition of glutamate-mediated excitation, blockade of voltage-dependent sodium or calcium channels being the most frequently shared. They are not only used for the symptomatic management of epilepsy but in the treatment of psychiatric or neurologic disorders (e.g. bipolar disorder, neuropathic pain, prophylaxis of migraine). Generally, this group of drugs is also widely used in neurosurgery patients for the prevention of seizure activity and their effectiveness in this regard has been evaluated in this review...

BACKGROUND: Epilepsy is a common condition with up to 1% prevalence in the general population. In the perioperative course of neurologic surgery patients, the use of prophylactic and therapeutic antiepileptic drugs is a common practice. Nonetheless, there is limited evidence supporting the use of prophylactic antiepileptics to prevent perioperative seizures and there are no guidelines for which anesthetic technique is preferred. OBJECTIVE: To discuss the seizurogenic potential of anesthetic drugs and to discuss intraoperative seizures in neurosurgical patients...
