BackgroundThis research sought to further validate the rat nitroglycerin (NTG) migraine model by comparing the effects of single versus recurrent NTG episodes on behavioral endpoints that mirror ICHD-3 diagnostic criteria for migraine, and to determine if the altered behavioral endpoints are reduced after administration of sumatriptan.MethodsSeparate cohorts of rats were administered NTG (10 mg/kg/2 ml) or saline (Experiment 1: single injection; Experiment 2: repeated injections; Experiment 3: repeated injections with sumatriptan [0.0, 0.3 and 1.0 mg/kg/ml] rescue. Behavioral endpoints were assessed 2 h after final NTG administration and included time in light/dark chambers for photophobia and activity, pain facial ratings, and cool (5 °C) and warm (46 °C) tail dip.ResultsThe first two experiments demonstrated that repeated (n = 5) but not single NTG injections produced photophobia, decreased activity, and yielded less weight gain than saline injections. Experiment 3 showed that sumatriptan attenuated hypoactivity, reduced facial expressions of pain, and reversed weight alterations in a dose-dependent manner.ConclusionsThese findings identify numerous clinical homologies of a recurrent NTG rat migraine model that may be useful for screening novel pharmacotherapies.

To address financial and scheduling conflicts associated with residency interviews for otolaryngology candidates, our residency program implemented virtual interviews as an alternative to the traditional in-person format for our visiting subinterns during the 2018-2019 and 2019-2020 interview cycles. Applicants then completed an anonymous survey about their interview experience. We found that, overall, positive attitudes toward virtual interviews increased among 2019-2020 candidates as compared with the year prior. Our results demonstrated an average cost savings per interview of $500 to $1000 when virtual technology was utilized. Based on feedback, improvements may be considered regarding eye contact, minimizing distractions, and providing the option to extend the interview length. Our experience provides a preliminary framework for transitioning to virtual interviews in the upcoming 2020-2021 otolaryngology residency selection process during the COVID-19 era, as well as for future studies assessing the utility of this method and its impact on overall match statistics.

Sentinel lymph node biopsy (SLNB) has been used across oncological specialties for prognostication, staging, and identification of occult nodal metastasis. Recent studies demonstrated the potential clinical utility of SLNB in oral cavity squamous cell carcinoma (OCSCC). Elective neck dissection is the current standard of care in early management of OCSCC with depth of invasion greater than 2-4 mm; however, majority of patients ultimately do not have nodal disease on final pathology. SLNB is an alternative procedure widely adopted in early cancer management in many oncological subspecialities. Several considerations such as depth of invasion, nodal mapping, histopathology methods, operator variability, postoperative complications, and advancement in preoperative and intraoperative imaging technology can guide the appropriate application to SLNB in OCSCC. The aim of this review is to discuss the current evidence for SLNB in the treatment of early stage OCSCC, imaging technologies that support SLNB procedures, and studies that are currently underway.
