RESUMO
INTRODUCTION: Several diagnostic modalities with various sensitivity and specificities can be used to evaluate a parotid mass. The aims of this project were to compare the diagnostic actionability, accuracy, and ability to accurately predict extent of surgery for FNA and frozen section during the evaluation of a parotid mass. METHODS: A retrospective chart review of patients who underwent parotidectomy for a parotid mass from January 1, 2015 to January 30, 2022 was conducted. Actionability was defined as a pathology diagnosis or the histologic grade of a lesion, as this provided clear and useful information for the surgeon to act upon. Diagnostic accuracy was determined by comparing FNA and frozen section results to final pathology. Accuracy of extent of surgery was determined by comparing predicted extent of surgery from the FNA or frozen section result to the extent of surgery predicted by the final pathology. RESULTS: A total of 626 patients were included in this study. FNA was obtained in 396 (63%) patients, while all neoplasms were evaluated by frozen section analysis. FNA diagnosis was actionable in 318 (80%), while frozen section diagnosis was actionable in 616 (98%) patients. Exactly 294 (92.5%) FNA diagnoses were accurate compared with 600 (98%) frozen section diagnoses. The FNA diagnosis predicted appropriate extent of surgery in 294 (74%) while the frozen section diagnosis predicted appropriate extent of surgery in 600 (96%). Among the 396 patients with FNA, frozen section was significantly more likely to accurately predict appropriate extent of surgery compared with FNA (p < 0.001). CONCLUSION: Frozen section is more likely to yield actionable and accurate results compared with FNA. Additionally, frozen section is better than FNA in predicting the appropriate extent of surgery.

The goal of the Xflows experimental campaign is to study the radiation flow on the National Ignition Facility (NIF) reproducing the sensitivity of the temperature (±8 eV, ±23 µm) and density (±11 mg/cc) measurements of the COAX platform [Johns et al., High Energy Density Phys. 39, 100939 (2021); Fryer et al., High Energy Density Phys. 35, 100738 (2020); and Coffing et al., Phys. Plasmas 29, 083302 (2022)]. This new platform will enable future astrophysical experiments involving supernova shock breakout, such as Radishock (Johns et al., Laboratory for Laser Energetics Annual Report 338, 2020) on OMEGA-60 [Boehly et al., Rev. Sci. Instrum. 66, 508 (1995)], and stochastic media (such as XFOL on OMEGA). Greater energy and larger physical scale on NIF [Moses et al., Eur. Phys. J. D 44, 215 (2007)] will enable a greater travel distance of radiation flow, higher density, and more manufacturable foams and enable exploration of a greater range of radiation behavior than achievable in the prior OMEGA experiments. This publication will describe the baseline configuration for the Xflows experimental campaign and the roadmap to achieve its primary objectives.
RESUMO
Burnout is just one of many ways that physicians unintentionally become impaired. This article reviews the relevant literature and issues facing physician wellness and presents information about the Missouri Physician and Health Professional Wellness Program sponsored by the Missouri Association of Osteopathic Physicians (MAOPS) and Capital Region Medical Center in Jefferson City, Missouri. Considerations for when to reach out in addition to information on some of the program's preventative services are provided.

PURPOSE: This study investigated the effect of strabismus on a child's playmate selection. METHODS: Photographs of orthotropic children aged 3-6 years were altered to simulate various magnitudes of strabismus. The pictures were arranged in pairs, one orthotropic child and one with strabismus. One hundred children aged 3-8 years viewed the photographs and were asked to select a playmate from each pair. RESULTS: Chi-squared analysis found 23 children showed evidence that strabismus influenced their choices (p < 0.07). Of these 23, 12 preferred playmates with strabismus and 11 preferred orthotropic playmates. Chi-squared analysis of all subjects combined found decisions were not based on the magnitude or direction of strabismus. CONCLUSIONS: As only 11% of the children consistently selected against playmates with strabismus, and about the same percentage preferred playmates with strabismus (12%), the presence of strabismus does not appear to be a significant factor in peer acceptance in this age group.

PURPOSE: The alternate cover test (ACT) measures the magnitude of a deviation, but different prism endpoints may be used. This study investigated the intraexaminer and interexaminer repeatability of the ACT using two different prism neutralization endpoints. METHODS: To determine repeatability of two prism neutralization endpoints (first neutral and midpoint of reversal), two experienced examiners measured near point phoria on 72 subjects. Measurements were repeated with examiners masked to each other and the first results. Paired t-tests were used to assess interexaminer and intraexaminer repeatability and the agreement between different prism endpoints for each examiner within each session. Signed and absolute differences in phoria magnitude were calculated. RESULTS: For two different test sessions with the same examiner using the same prism neutralization endpoint (intraexaminer repeatability), none were significant except examiner 1 using first neutral (p = 0.038). Average signed differences (ASD's) between two test sessions for each comparison were <0.5 prism diopter (pd) with SD's of =2.56 pd. Absolute differences ranged from 1.30 to 1.89 pd. When two different examiners used the same prism endpoint within the same session (interexaminer repeatability), there were no significant differences between examiners. ASD's between the two examiners for each comparison were =0.53 pd with SD's =2.03 pd. The absolute differences ranged from 1.19 to 1.67 pd. Comparisons of the two different prism endpoints by the same examiner at a single test session were all significantly different (p < 0.005), but the differences (<1 pd between the two endpoints) were not clinically significant. ASD's were <1 pd with SD <2 pd. Absolute differences ranged from 1 to 1.58 pd. CONCLUSIONS: With experienced examiners, either prism endpoint provides high interexaminer and intraexaminer repeatability (=0.5 pd). Although the two prism endpoints differ statistically, the differences are not clinically significant.
