Specific afterdischarge properties can enhance the clinical utility of electrical stimulation mapping during intracranial monitoring.

Objective: Extraoperative electrical cortical stimulation (ECS) facilitates defining the seizure onset zone (SOZ) and eloquent cortex. The clinical relevance of stimulation-induced afterdischarges (ADs) is not well defined.

Methods: Fifty-five patients who underwent intracranial electroencephalogram evaluations with ECS were retrospectively identified.

Trends of Odontogenic Sinusitis Incidence During the COVID-19 Pandemic.

Objectives: The COVID-19 pandemic affected the epidemiology of several diseases. This study aims to compare the incidence of surgically treated odontogenic sinusitis (ODS) before and during the COVID-19 pandemic and identify unique features.

Methods: A retrospective chart review of patients who underwent at least maxillary antrostomy at a tertiary referral center was performed.

Subjective and Objective Taste Change After Cochlear Implantation Systematic Review and Meta-Analysis.

Introduction: There is a paucity of data reporting the rate of chorda tympani nerve injury during cochlear implantation (CI) surgery. To better provide clarity to patients and surgeons regarding the risk of taste change, we performed a systematic review and meta-analysis of prospective studies examining taste change after CI.

Data Sources: PubMed, Embase, and Cochrane Library databases were queried.

Cochlear implants and deep brain stimulators.

Objective And Importance: With an aging population and increasing utilization of both cochlear implants (CI) to treat hearing loss and deep brain stimulation (DBS) to treat neurodegenerative movement disorders, more patients will be sequentially implanted with the two devices. As such, understanding both presurgical evaluations and surgical procedures will be of great importance to the treating cochlear implant surgeon and neurosurgeon in optimizing outcomes for both conditions.

Clinical Presentation: Two illustrative cases of sequential CI followed by DBS are reviewed.

T2 Hypointense Schwannoma Masquerading As A Vascular Lesion: A Case Report.

Spinal schwannomas are rare nerve root tumors that typically produce subtle symptoms from nerve root compression. These tumors are known to be heterogeneously hyperintense on T2-weighted MRI and avidly enhance with contrast. However, here we describe an L5 spinal schwannoma in a 66-year-old woman that was hypointense on T2-weighted imaging with other radiographic findings more closely aligning with a vascular lesion.

Iatrogenic traumatic superficial temporal arteriovenous fistula development post-craniectomy: A case report.

We report a case of superficial temporal arteriovenous fistula development following frontotemporoparietal hemicraniectomy. This patient presented with intracerebral hemorrhage (ICH) secondary to underlying arteriovenous malformation (AVM) rupture. Following decompressive hemicraniectomy and follow-up successful resection of the underlying AVM, the patient returned to the hospital with a seizure.

Predictors of smell recovery in a nationwide prospective cohort of patients with COVID-19.

Objective: To determine which factors (demographic, symptoms, comorbidities, and treatments) are associated with recovery of smell in patients with COVID-19 associated olfactory loss.

Study Design: Prospective, longitudinal questionnaires.

Setting: National survey.

Quality of life and safety impact of COVID-19 associated smell and taste disturbances.

Objective: The association between COVID-19 and chemosensory loss has garnered substantial attention, however to date little is known about the real-life consequences of impairment in this unique patient population. The aim of this study is to evaluate the quality of life (QOL) and personal safety deficits experienced by patients with COVID-19 infection.

Study Design: Prospective, longitudinal questionnaires.

Subjective smell and taste changes during the COVID-19 pandemic: Short term recovery.

Since the COVID-19 pandemic began, many individuals have reported acute loss of smell and taste. In order to better characterize all patients with these symptoms, a longitudinal national survey was created. Since April 10, 2020, 549 completed the initial survey, with 295 completing 14-day, and 202 completing 1-month follow up surveys.

l-Arginine supplementation in severe asthma.

BACKGROUNDDysregulation of l-arginine metabolism has been proposed to occur in patients with severe asthma. The effects of l-arginine supplementation on l-arginine metabolite profiles in these patients are unknown. We hypothesized that individuals with severe asthma with low fractional exhaled nitric oxide (FeNO) would have fewer exacerbations with the addition of l-arginine to their standard asthma medications compared with placebo and would demonstrate the greatest changes in metabolite profiles.

Subjective Changes in Smell and Taste During the COVID-19 Pandemic: A National Survey-Preliminary Results.

Since the COVID-19 pandemic began, many individuals have noted acute loss of smell and/or taste, although not all patients with these symptoms are tested for COVID-19. To better characterize all patients with these rare symptoms, a national survey was created. Over 13 days in April 2020, a total of 220 people completed the survey in its entirety, representing a wide geographic distribution across the United States.
