RESUMO

OBJECTIVES/HYPOTHESIS: Dermal filler (DF) is a widely used nonsurgical option for facial rejuvenation with a rapidly expanding market. Physician payments by DF industry leaders have yet to be characterized. We sought to investigate trends in physician-industry payments by DF companies over 6 years. Differences in payments based on physician specialty and time were characterized. STUDY DESIGN: Database review. METHODS: The Open Payments Database was queried from 2013 to 2018. Payments made by the three largest DF companies by market share to otolaryngologists, plastic surgeons, and dermatologists were analyzed. Total dollars paid, number of payments made, type of payments made, and total number of specialists paid were recorded. One-way ANOVA was used for statistical analysis. RESULTS: Otolaryngologists, plastic surgeons, and dermatologists received average annual payments of $0.36 million, $6.3 million, and $6.6 million respectively (P < .001). An average of 330 otolaryngologists, 2,128 plastic surgeons, and 5,980 dermatologists were paid annually (P < .001). Accredited speaking arrangements, consulting fees, and royalty/licensing fees comprised the majority of dollars paid to physicians. CONCLUSIONS: Average physician payment by DF companies exceeds $12 million annually, with otolaryngologists receiving significantly less compared to plastic surgeons and dermatologists. LEVEL OF EVIDENCE: NA Laryngoscope, 132:301-306, 2022.

RESUMO

INTRODUCTION: Mucoepidermoid carcinoma (MEC) of the upper aerodigestive tract (UADT) is an uncommon malignancy, with limited literature available on its clinical and pathologic characteristics. Here, we describe the behavior of MEC of the UADT including pathologic characteristics and predictors of nodal metastasis. METHODS: Retrospective cohort study of patients with MEC of the UADT treated at an academic medical center from January 2008 to May 2018. Data was collected about demographics and tumor characteristics including clinical and histological data. The two-tailed Student t test and χ2 analysis were performed to assess for predictors of nodal metastasis. RESULTS: We identified 44 patients with minor salivary gland MEC of the oral cavity (OC) and oropharynx (OP). All patients were treated with primary site surgery. The primary site was the OC in 25 patients (57%) and OP in 19 (43%). Low-grade histology was seen in 27 specimens (61.4%), intermediate histology in 9 specimens (20.5%), and high-grade histology in 8 specimens (18.2%). Perineural invasion was noted in 10 specimens (22.7%). Neck dissection was performed in 17 patients (39%), with pathologically positive nodes found in 9 (20.5%). Notably, 5 of the 9 positive nodal specimens were found in clinically node-negative necks. Pathologically positive cervical lymph nodes were significantly associated with the OP as the primary site (p = 0.0005), perineural invasion (p = 0.012), lymphovascular invasion (p < 0.001), and high-grade histology (p = 0.004) in the primary specimen. DISCUSSION: MEC of the UADT is an uncommon malignancy. Our findings suggest elective neck dissection should be considered with perineural and lymphovascular invasion, high-grade tumor, and the OP as the primary site.

RESUMO

OBJECTIVE: We present the largest population based study of sinonasal squamous cell carcinoma (SCC) to identify risk factors for presentation with nodal metastasis. METHODS: The National Cancer Database (NCDB) was used for this study. Location codes corresponding to the nasal cavity and paranasal sinuses and histology codes representing SCC malignancy were queried. Logistic regression analysis was performed to identify factors associated with presentation with nodal metastasis. RESULTS: 6448 cases met inclusion criteria. Nodal metastasis at presentation was seen in 13.2% of patients, with the sinus subsite (19.3%) being a significant risk factor for nodal metastasis at presentation when compared to the nasal cavity (7.9%). Logistic regression analysis showed black, uninsured and Medicaid patients were more likely than white and privately insured patients, respectively, to present with nodal metastasis. CONCLUSIONS: In sinonasal SCC, the sinus subsite has a significantly increased risk of nodal metastasis compared to the nasal cavity. Black race, uninsured and Medicaid patients are more likely to have nodal metastasis at presentation.

RESUMO

BACKGROUND: Gun violence remains a staggering public health care crisis. Although viewing the victim's body is essential to the grieving process, this practice is not universally practiced in the trauma bay and may not be supported by nurses. This study investigates how trauma nurses perceive bereavement and the potential barriers to family viewing after death by gun violence. METHODS: A survey designed to assess demographics, current practices, knowledge of policies, and personal beliefs regarding family viewing after violent crime was sent electronically to members of the Society of Trauma Nurses. Participants were asked to rank the importance of 14 viewing barriers. Descriptive analysis and perception of barriers between those who did and did not permit viewing were compared using Mann-Whitney tests. *P < 0.05 is considered significant. RESULTS: Of the 212 participants, the majority were white, female nurses (86%), aged 30 to 60 y who worked in an urban or suburban setting (58% and 30%). Only 15% had a written hospital policy with the majority not knowing if the police (68%) or medical examiner (74%) had written policies. Despite lack of guidelines, viewings did routinely occur (68%), but only 37% permitted touching. Nurses who did not permit viewing were more likely to rank legal concerns and trauma bay environment as significant barriers. CONCLUSIONS: Although family viewing after gun violence frequently occurs in the trauma bay, there are significant barriers that are compounded by lack of formal policies. Collaboration with police and medical examiners could mitigate these fears while promoting a safe and more family-centered experience.

RESUMO

Human pluripotent stem cells (hPSCs) offer a renewable source of cells that can be expanded indefinitely and differentiated into virtually any type of cell in the human body, including neurons. This opens up unprecedented possibilities to study neuronal cell and developmental biology and cellular pathology of the nervous system, provides a platform for the screening of chemical libraries that affect these processes, and offers a potential source of transplantable cells for regenerative approaches to neurological disease. However, defining protocols that permit a large number and high yield of neurons has proved difficult. We present differentiation protocols for the generation of distinct subtypes of neurons in a highly reproducible manner, with minimal experiment-to-experiment variation. These neurons form synapses with neighboring cells, exhibit spontaneous electrical activity, and respond appropriately to depolarization. hPSC-derived neurons exhibit a high degree of maturation and survive in culture for up to 4-5 months, even without astrocyte feeder layers.
