Résumé

Introducción La enfermedad por coronavirus 2019, o COVID-19, se ha convertido en una pandemia. Dada que la mayor carga viral de coronavirus de tipo 2 causante del síndrome respiratorio agudo severo (SARS-CoV-2) se encuentra en la vía aérea, los otorrinolaringólogos tienen un elevado riesgo de infección. Múltiples recomendaciones han surgido con respecto a las medidas de protección, incluidos la suspensión de procedimientos y cirugías electivas. Objetivos Evaluar el impacto de la pandemia de COVID-19 en los programas de formación de otorrinolaringología a nivel nacional. Métodos Estudio transversal de encuesta en línea a residentes de otorrinolaringología realizado durante abril de 2020. Se analizaron datos demográficos, actividades clínicas, turnos de llamado, infección por COVID-19, exposición a pacientes COVID-19 positivos, despliegue a otras especialidades, procedimientos y cirugías realizadas. Se utilizaron los portafolios quirúrgicos de años previos para comparar los resultados. Resultados Completaron la encuesta 47 residentes, con 84% de tasa de respuesta; el 64% refirió haber acudido a su centro asistencial 10 días o menos durante el mes de abril de 2020. Con relación a procedimientos frecuentes tales como nasofibroscopía, endoscopia nasal rígida y drenaje de absceso periamigdalino, no fueron realizados por más del 40% de los residentes en el mes. Solo el 38% participó en cirugías, con un promedio de 0,6 procedimientos como primer cirujano; se constata una drástica disminución al comparar los registros de años anteriores. La mayoría de los residentes refieren estas medidas educativas complementarias: videoconferencias bibliográficas (87%), seminarios de casos clínicos en línea (60%), revisión de artículos (38%), entre otros. Conclusiones La formación clínica y quirúrgica disminuyó drásticamente durante abril de 2020. Se deben considerar ajustes a los planes de estudio para disminuir el impacto negativo de la pandemia en la formación de los residentes.


Introduction Coronavirus disease 2019, or COVID-19, has become a global pandemic. Given that the highest viral load of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is found in the airway, otolaryngologists are at high risk of infection. As a result, multiple recommendations have emerged regarding protective measures for surgical teams, including suspending non-urgent procedures and surgeries. Objectives To evaluate the impact of the COVID-19 pandemic on otolaryngology residency training programs nationwide. Methods A cross-sectional survey-based study was completed in April 2020. The participants were recruited through an online survey, sent by email to all Chilean otolaryngology residents. Demographics, clinical activities, on-call shifts, COVID-19 infection status, exposure to COVID-19 patients, deployment to other specialties, diagnostic/therapeutic procedures, and surgeries performed were analyzed. Self-reported surgical data logs from previous years were used to compare results. Results Forty-seven residents completed the survey (84% response rate); 64% of residents refer seeing patients ten days or less during April 2020. Commonly performed procedures such as flexible nasolaryngoscopy, rigid nasal endoscopy, and peritonsillar abscess drainage were not performed by over 40% of the residents in that month. Only 38% participated in surgeries, with an average of 0.6 surgeries as a first surgeon, a dramatic decrease in surgical exposure when comparing the data logs from previous years. Most residents refer the following measures taken by their residency program to improve residency training: bibliographic videoconferences (87%), online clinical case seminars (60%), weekly journal clubs (38%), among others. Conclusions Clinical and surgical opportunities decreased dramatically during April 2020. Adjustments to the regular academic curricula should be considered to decrease the negative impact of this pandemic on residency training.

Résumé

In the last decades, there has been an increase in life expectancy in the world, with the consequent modification in the proportion of adults over 60 years. This is accompanied by an increase in pathologies for which aging is the main risk factor, such as dementia and hearing loss, which profoundly affect the quality of life of individuals and their family and impact health system costs. Given the lack of disease-modifying treatments for dementia, the study of mechanisms to prevent its occurrence has become a world priority. In the year 2017, the Lancet "Commission for dementia prevention, intervention, and care" proposed a model, in which hearing loss emerged as a new modifiable risk factor for the development of dementia. This result undoubtedly has important consequences for the understanding the multifactorial nature of dementia, our daily clinical practice and public policies aimed at its prevention and treatment. In this article, we review the current evidence supporting the association between dementia and hearing loss, discussing the available strategies for prevention, detection and treatment of hearing loss and its possible impact on the natural course of dementia. A flow chart for the clinical management of different subgroups of patients is proposed.

Résumé

Hearing loss is the most common inherited sensorial deficiency in humans; about 1 in 1000 children suffer from severe or profound hearing loss at birth. Mutations in the GJB2 gene are the most common cause of prelingual, non-syndromic autosomal recessive deafness in many populations; the c.35delG mutation is the most common in Caucasian populations. The frequency of the c.35delG mutation was estimated in two samples of deaf patients from Santiago, Chile. Unrelated non-syndromic sensorioneural deaf patients were examined: Group 1 consisted of 47 unrelated individuals with neurosensory deafness referred to the Chilean Cochlear Implant Program; Group 2 included 66 school children with prelingual deafness attending special education institutions for deaf people. Individuals with profound to moderate isolated neurosensory hearing loss with unknown etiology were included. The presence of the c.35delG mutation was evaluated by the allele-specific polymerase chain reaction method (PCR), and in some cases it was confirmed by direct DNA sequencing of the coding region of the GJB2 gene. Deaf relatives were present in 20.3% of the cases. We found 19.5% (22/113) patients with the c.35delG mutation, 6 of them homozygous; these rates are similar to frequencies found in other Latin American countries.

Résumé

Se presentan dos casos de recién nacidos con alteraciones compatibles con el síndrome de bridas amnióticas. El primero presenta posturas viciosas de extremidades inferiores y mutilaciones de las superiores, además de labio leporino complicado. El segundo caso corresponde a una brida facionucal que practicamente separa la boca del resto de la cara. A la luz de ambos casos se hace una revisión crítica de las teorías etiológicas planteadas en la literatura
