Abstract Introduction The COVID-19 pandemic has led to a reduction in surgical and clinical volume, which has altered the traditional training experience of the otolaryngology resident. Objective To describe the strategies we utilized to maximize resident education as well as ensure patient and staff safety during the pandemic. Methods We developed a system that emphasized three key elements. First and foremost, patient care remained the core priority. Next, clinical duties were restructured to avoid unnecessary exposure of residents. The third component was ensuring continuation of resident education and maximizing learning experiences. Results To implement these key elements, our residency divided up our five hospitals into three functional groups based on geographical location and clinical volume. Each team works for three days at their assigned location before being replaced by the next three-person team at our two busiest sites. Resident teams are kept completely separate from each other, so that they do not interact with those working at other sites. Conclusions Despite the daily challenges encountered as we navigate through the COVID-19 pandemic, our otolaryngology residency program has been able to establish a suitable balance between maintenance of resident safety and well-being without compromise to patient care.

Abstract Aortic valve disease is one of the most common valvular heart diseases in the cardiovascular category. Surgical replacement of the diseased aortic valve remains the definitive intervention for most diseases. There is a clear consensus that in young patients who require aortic valve replacement, a mechanical prosthesis is the preferred choice due to its durable prosthesis without fear of wear and tear over time. However, this comes at the expense of increased risk of bleeding and thromboembolic events; in addition, there is a lack of strict evidence in using bioprosthesis in patients younger than 50 years. The objective of this review article is to assess the current evidence behind using bioprosthetic aortic valve in this young cohort.

Resumo Justificativa: A intubação seletiva neonatal do brônquio principal esquerdo para tratar a doença pulmonar direita é tipicamente feita com elaboradas manobras, instrumentação e dispositivos. Isso é frequentemente atribuído à geometria brônquica que favorece a entrada principal direita de um tubo endotraqueal (TET) deliberadamente avançado para além da carina. Resumo do caso: Recém-nascido com enfisema bolhoso grave que afetava o pulmão direito e precisou com urgência da não ventilação desse pulmão. Para conseguir a intubação brônquica esquerda fizemos uma rotação de 180° do TET, de forma que o olho de Murphy ficasse voltado para a esquerda, e não para a direita, e para simular uma intubação à esquerda orientamos ligeiramente o TET, de modo que sua concavidade virasse para a esquerda em vez de para a direita, como em uma intubação convencional à direita. Conclusão: A intubação urgente do brônquio principal esquerdo com um TET pode ser facilmente obtida se reconhecermos que é a posição da ponta do TET e a direção de sua concavidade que determinam para qual brônquio o TET irá quando avançado. Isso é importante em neonatos criticamente doentes diante da margem de segurança e janela de tempo pequenas e na ausência de tubos de duplo lúmen. O uso de broncofibroscópio e bloqueadores deve ser considerado como planos de segurança.

Abstract Background: Selective neonatal left mainstem bronchial intubation to treat right lung disease is typically achieved with elaborate maneuvers, instrumentation and devices. This is often attributed to bronchial geometry which favors right mainstem entry of an endotracheal tube deliberately advanced beyond the carina. Case summary: A neonate with severe bullous emphysema affecting the right lung required urgent non-ventilation of that lung. We achieved left mainstem bronchial intubation by turning the endotracheal tube 180° such that the Murphy's eye faced the left instead of the right, and simulated a left-handed intubation by slightly orientating the endotracheal tube such that its concavity faced the left instead of the right as in a conventional right-handed intubation. Conclusion: Urgent intubation of the left mainstem bronchus with an endotracheal tube can be easily achieved by recognizing that it is the position of the endotracheal tube tip and the direction of its concavity that are the chief determinants of which bronchus an endotracheal tube goes when advanced. This is important in critically ill neonates as the margin of safety and time window are small, and the absence of double-lumen tubes. Use of fiberoptic bronchoscope and blockers should be reserved as backup plans.

Antecedentes. La valoración del riesgo de violencia es un requisito fundamental en la toma de decisiones profesionales que implican prevenir, intervenir o informar sobre la conducta de las personas. El uso de herramientas estructuradas de evaluación del riesgo de violencia ha mostrado mejoría en la precisión de las evaluaciones basadas exclusivamente en el juicio clínico o en la pericia de un experto en contextos psiquiátricos, penitenciarios y jurídicos. Objetivo. Este estudio presenta los resultados de la primera encuesta sobre las prácticas profesionales asociadas al uso de herramientas de evaluación del riesgo de violencia en España. Materiales y métodos. La información fue recogida mediante la administración de una encuesta en internet que fue distribuida por correo electrónico a los miembros de organizaciones profesionales. Resultados. De manera similar a los contextos profesionales del resto del mundo, las escalas de psicopatía de Robert Hare (Psychopathy Checklist-Revised y Psychopathy Checklist: Screening Version) y el Historical-Clinical-Risk Management-20 encabezaron la lista de las herramientas más usadas tanto por elección personal como por requisito institucional. Conclusiones. Se ofrecen datos novedosos sobre la prevalencia de uso y la utilidad percibida de las herramientas estructuradas, así como sobre otras cuestiones relacionadas a las prácticas profesionales de evaluación del riesgo de violencia en España que pueden orientar tanto a los profesionales de contextos sanitarios, correccionales y forenses, como a los responsables de las instituciones en la elección de las herramientas a implementar para asistirlos en la toma de decisiones.

Background. Violence risk assessment is a key requirement in professional decision making involving prevention, intervention or reporting on human behavior. The use of structured tools for violence risk assessment has shown to improve the accuracy of assessments based exclusively on clinical judgment or expertise in psychiatric, correctional and legal settings. Objectives. This study presents results of the first survey about professional practices associated with tools for violence risk assessment in Spain. Materials and methods. The information was collected by administering an online-based survey that was distributed by e-mail to members of professional organizations around the country. Results. As in professional contexts worldwide, the Robert Hare's psychopathy scales (Psychopathy Checklist-Revised and Psychopathy Checklist: Screening Version) and the Historical-Clinical-Risk Management-20 topped the list of the most used tools both by professional choice and institutional requirement. Conclusions. We provide novel data on the prevalence of use and the perceived utility of specific tools, as well as on other issues related to the professional practice of violence risk assessment in Spain, which can guide professional in the health care, correctional and forensic settings, as well as those responsible for decisions in institutions about choosing which tool to implement.

FUNDAMENTO: O bloqueio completo do ramo esquerdo esforço-induzido (BCRE E-I) é um achado infrequente ao teste de exercício e sua prevalência e significado prognóstico não são claros. OBJETIVO: Avaliar de forma longitudinal a prevalência e o significado prognóstico do BCRE E-I em homens americanos veteranos de guerra. MÉTODOS: Avaliamos 9.623 pacientes que realizaram ergometria em esteira (TE) entre 1987 e 2007. Os desfechos foram comparados entre aqueles com TE NL, os com BCRE E-I e os que apresentaram Dep ST anormal. A mortalidade e a causa das mortes foram identificadas de forma cega para os resultados do TE. RESULTADOS: Nesta coorte prospectiva, 6922 indivíduos apresentaram TE NL (57,2 ± 11,4 anos), 1.739 apresentaram Dep ST anormal (62,7 ± 9,8 anos) e 38 casos de BCRE E-I foram identificados (65,2 ± 11,9 anos). A prevalência do BCRE E-I foi 0,38%. Após 8,8 anos, ocorreram 1.699 mortes por todas as causas e 610 mortes cardiovasculares (CV). Doença arterial coronária e insuficiência cardíaca foram mais prevalentes nos pacientes com BCRE E-I. Pacientes com BCRE E-I tiveram razão de azar de 2,37 (p = 0,002) para mortalidade por todas as causas, mas a mesma não foi significativa quando ajustada para idade ou quando a mortalidade cardiovascular foi o desfecho avaliado. CONCLUSÃO: BCRE E-I é um achado raro. Indivíduos com BCRE E-I apresentam maior mortalidade por todas as causas quando comparados aqueles com TE NL. No entanto, tal fato é explicado por esses pacientes serem significativamente mais velhos e por apresentarem mais enfermidades cardiovasculares associadas.

BACKGROUND: Exercise-induced left bundle branch block (EI-LBBB) is an infrequent finding. Its prevalence and prognostic significance are not clear. OBJECTIVE: To evaluate, in a longitudinal study, the prevalence and prognostic significance of EI-LBBB in American war veterans. METHODS: We evaluated 9,623 patients submitted to an exercise test (ET) in treadmill between 1987 and 2007. The outcomes were compared between those with normal TE, the ones with EI-LBBB and the ones with down-sloping ST-segment. Mortality and causes of death were identified while blinded to the ET results. RESULTS: In this prospective cohort, 6,922 individuals had normal ET results (57.2 ± 11.4 years), 1,739 had abnormal ST-segment depression (62.7 ± 9.8 years), and 38 had EI-LBBB (65.2 ± 11.9 years). The prevalence of EI-LBBB was 0.38%. After 8.8 years, there were 1,699 deaths due to all-cause mortality and 610 cardiovascular (CV) deaths; coronary artery disease and heart failure were more prevalent in patients with EI-LBBB. Patients with EI-BCRE had a hazard ratio of 2.37 (p = 0.002) for all-cause mortality, but it was not significant when adjusted for age or when the CV death was the assessed outcome. CONCLUSION: EI-LBBB is a rare clinical finding. Individuals with BCRE-EI have higher all-cause mortality when compared to those with normal ET results. However, this fact is explained by the fact that these patients are significantly older and have more associated cardiovascular diseases.

FUNDAMENTO: El bloqueo completo de rama izquierda esfuerzo-inducido (BCRI E-I) es un hallazgo infrecuente en el test de ejercicio y su prevalencia y significado pronóstico no son claros. OBJETIVO: Evaluar de forma longitudinal la prevalencia y el significado pronóstico del BCRI E-I en los hombres norteamericanos veteranos de guerra. MÉTODOS: Evaluamos 9.623 pacientes que realizaron ergometría en cinta (TE) entre 1987 y 2007. Los resultados fueron comparados entre aquellos con TE normal (TE NL), los con BCRI E-I y los que presentaron infradesnivel del segmento ST (Dep ST) anormal. La mortalidad y la causa de las muertes fueron identificadas de forma ciega para los resultados del TE. RESULTADOS: En esta cohorte prospectiva y después de las exclusiones, 6.922 individuos presentaron EC NL (57,2 ± 11,4 años), 1739 tuvieron Dep ST anormal (62,7 ± 9,8 años), y 32 casos de BCRI E-I fueron identificados (65,2 ± 11,9 años). La prevalencia del BCRI E-I fue del 0,38%. Después de 8,8 años, ocurrieron 1699 muertes por todas las causas y 610 muertes cardiovasculares (CV). La enfermedad arterial coronaria y la insuficiencia cardíaca fueron las más prevalentes en los pacientes con BCRI E-I. Los pacientes con BCRI E-I presentaron azar de 2,37 (p = 0,002) para la mortalidad por todas las causas, pero ella no fue significativa cuando se ajustó para la edad o cuando la mortalidad cardiovascular fue el desenlace evaluado. CONCLUSIÓN: BCRI E-I es un hallazgo raro. Los individuos con BCRI E-I presentan una mayor mortalidad por todas las causas cuando se les compara con los de EC NL. Sin embargo, ese hecho se explica porque esos pacientes son significativamente más viejos y por presentar más enfermedades cardiovasculares asociadas.
