Jacobson's nerve schwannoma presenting as middle ear mass

Schwannoma is one of the common benign middle ear space tumors. Middle ear space schwannomas may originate from the nerves of the tympanic cavity or by extensions From outside the middle ear space. In the English-language literature, the facial nerve and chorda tympani nerve, but not yet the tympanic branch of glossopharyngeal nerve (Jacobson's nerve), have been reported as the origins of intrinsic middle ear space schwannomas. We present the clinical and radiologic features of a middle-space schwannoma originating from Jacobson's nerve, and suggest that such a tumor be included in the differential diagnosis of middle ear tumors

Seawater carbonate chemistry parameters model simulation results for Santa Barbara Basin, link to xlsx file

The 2013-2014 model‐based estimates of the carbonate system variables (total alankinity (TA), dissolved inorganic carbon (DIC), and saturation state of araongite and calcite (Ω)) and water column parameters (temperature, salinity, and nitrate concentration) near the site of the sediment trap in the Santa Barbara Basin stem from the simulations described in detail by Turi et al. (2016). Simulated water column parameters span from the sea surface (0 meters) to approximately 275 meters water depth. Based on these simulated values, the carbonate system calculation program, CO2SYS was used to estimate the remaining components of the carbonate system, including pH the fugacity, partial pressure, and concentration of CO2, bicarbonate ion, carbonate ion. The model is based on the UCLA‐ETH version of the Regional Oceanic Modeling System (Shchepetkin & McWilliams, 2005) and includes a nitrogen‐based nutrient‐phytoplankton zooplankton‐detritus model (Gruber et al., 2006) that was extended with a carbon module (Gruber et al., 2012; Hauri et al., 2013). The CalCS model setup employed here has a horizontal resolution of 5 km and 34 levels in the vertical and spans the entire U.S. coast from about 30°N to 50°N and extends more than 1,300 km into the Pacific. The boundary conditions at the lateral boundaries of the model consisted of a combination of climatological fields based on observations and time‐varying anomaly fields derived from a global hindcast simulation with the NCAR CCSM3 model (Graven et al., 2012)

Boron to calcium ratios (B/Ca) of sediment trap collected planktonic foraminifera from the Santa Barbara Basin

These data are in association with a study conducted in the Santa Barbara Basin, California, USA that were used to calibrate and evaluate the boron to calcium ratio (B/Ca) of three species of planktonic foraminifera. Geochemistry data measured by HR-ICP-MS were generated for the G. bulloides, N. dutertrei and N. incompta species. Shell characteristics, specifically area-normalized shell weight (ANSW) measurements and individual shell geochemistry (LA-ICP-MS) were generated for G. bulloides as a part of a cryptic species analyses. Additional information on collection of ANSW data can be obtained in Osborne et al., (2016) publication in Paleoceanography (doi:10.1002/2016PA002933). Modeled marine carbonate system variables for our study site were used for comparison to foraminiferal B/Ca datasets

American Neurotology Society, American Otological Society, and American Academy of Otolaryngology - Head and Neck Foundation Guide to Enhance Otologic and Neurotologic Care During the COVID-19 Pandemic

: This combined American Neurotology Society, American Otological Society, and American Academy of Otolaryngology - Head and Neck Surgery Foundation document aims to provide guidance during the coronavirus disease of 2019 (COVID-19) on 1) priority of care for otologic and neurotologic patients in the office and operating room, and 2) optimal utilization of personal protective equipment. Given the paucity of evidence to inform otologic and neurotologic best practices during COVID-19, the recommendations herein are based on relevant peer-reviewed articles, the Centers for Disease Control and Prevention COVID-19 guidelines, United States and international hospital policies, and expert opinion. The suggestions presented here are not meant to be definitive, and best practices will undoubtedly change with increasing knowledge and high-quality data related to COVID-19. Interpretation of this guidance document is dependent on local factors including prevalence of COVID-19 in the surgeons\u27 local community. This is not intended to set a standard of care, and should not supersede the clinician\u27s best judgement when managing specific clinical concerns and/or regional conditions.Access to otologic and neurotologic care during and after the COVID-19 pandemic is dependent upon adequate protection of physicians, audiologists, and ancillary support Northwell Health. Otolaryngologists and associated Northwell Health are at high risk for COVID-19 disease transmission based on close contact with mucosal surfaces of the upper aerodigestive tract during diagnostic evaluation and therapeutic procedures. While many otologic and neurotologic conditions are not imminently life threatening, they have a major impact on communication, daily functioning, and quality of life. In addition, progression of disease and delay in treatment can result in cranial nerve deficits, intracranial and life-threatening complications, and/or irreversible consequences. In this regard, many otologic and neurotologic conditions should rightfully be considered urgent, and almost all require timely attention to permit optimal outcomes. It is reasonable to proceed with otologic and neurotologic clinic visits and operative cases based on input from expert opinion of otologic care providers, clinic/hospital administration, infection prevention and control specialists, and local and state public health leaders. Significant regional variations in COVID-19 prevalence exist; therefore, physicians working with local municipalities are best suited to make determinations on the appropriateness and timing of otologic and neurotologic care
