Translation and cultural adaptation of "Glasgow Children's Benefit Inventory" into Brazilian Portuguese

Abstract Objective Translate and cross-culturally adapt into Brazilian Portuguese the Glasgow Children's Benefit Inventory instrument used for the quality-of-life assessment after pediatric ENT interventions. Method This is a methodological study of translation and cross-cultural adaptation of the GCBI instrument following seven stages: 1) Translation of two versions by two independent translators, 2) Elaboration of a consensual synthetized version, 3) Assessment of the synthetized version by experts, 4) Assessment by the target audience, 5) Back-translation, 6) Pilot study and 7) Use of the instrument. The final version of the instrument was answered by a sample of 28 people responsible for children aged from 2 to 7 years, submitted to tonsillectomy between January 2019 and December 2021, in a public hospital in Porto Alegre. The collection considered patients with a minimum of 6-months and a maximum of 3-years of postoperative follow-up. Result The instrument final version was compared to the original version showing semantic equivalence, absence of consistent translation difficulties and appropriate cross-cultural adaptation, and well understood by the target audience. The application of the questionnaire in the sample showed a Cronbach alpha coefficient of 0.944 corresponding to a high degree of reliability of the instrument. Conclusion The translation and cross-cultural adaptation showed semantic appropriateness and its use when assessing ENT postoperative results in a pediatric population showed high reliability of the instrument. Level of evidence 4.

Is it Always Laryngopharyngeal Reflux? How Voice Disorders Can Manifest as LPR

Introduction: Laryngopharyngeal reflux (LPR) manifests with a constellation of common throat symptoms and inconclusive signs on laryngoscopic exam. It is a diagnosis, often made clinically, that can lead to prescriptions of proton pump inhibitors that are unnecessary and potentially harmful. Glottic insufficiency (GI) and the accompanying hyperfunctional laryngeal behaviors can also present with similar, common throat complaints that may or may not include a qualitative change to the voice. Methods: This is a reflection article. It is written to summarize, explain, and support with evidence the opinion of the author on the topic of how symptoms of voice disorders can easily be mistaken for symptoms of LPR. The offered reflection is based on his experience, research and the available literature. Reflection: This article intends to explore the similarities between GI and LPR, how to ultimately differentiate them and how to approach treatment with a broader differential diagnosis. Conclusion: LPR and GI can present with identical, vague throat, and voice symptoms. Empiric medication trials, behavioral interventions and objective laryngovideostroboscopy, impedance-based reflux, and esophageal motility testing may all be needed, sometimes in a trial and error fashion, to correctly diagnose and treat a patient's symptoms.

Introducción: El reflujo laríngeo-faríngeo (LPR, por sus siglas en inglés) se manifiesta con una serie de síntomas comunes en la garganta y signos no concluyentes en el examen larinoscópico. Es un diagnóstico que a menudo se realiza clínicamente y que puede llevar a la prescripción de inhibidores de la bomba de protones que son innecesarios y potencialmente perjudiciales. La insuficiencia glótica (IG) y los comportamientos laríngeos hiperfuncionales que la acompañan también pueden presentar síntomas de garganta comunes similares, que pueden o no incluir un cambio cualitativo en la voz. Métodos: Este es un artículo de reflexión. Está escrito para resumir, explicar y respaldar con evidencia la opinión del autor sobre cómo los síntomas de los trastornos de la voz pueden confundirse fácilmente con los síntomas del LPR. La reflexión ofrecida se basa en su experiencia, investigación y la literatura disponible. Reflexión: Este artículo tiene la intención de explorar las similitudes entre la IG y el LPR, cómo diferenciarlos finalmente y cómo abordar el tratamiento con un diagnóstico diferencial más amplio. Conclusión: El LPR y la IG pueden presentar síntomas idénticos y vagos en la garganta y la voz. Puede ser necesario realizar ensayos de medicación empírica, intervenciones conductuales y pruebas objetivas de laringovideostroboscopia, reflujo basado en impedancia y motilidad esofágica, a veces de manera experimental, para diagnosticar y tratar correctamente los síntomas de un paciente.

The Value of Multiple Medication Trials Prior to Balloon Sinuplasty in the Management of Chronic Sinonasal Disease

Abstract Introduction In patients with chronic rhinosinusitis, conservative interventions with extended medical trials are often attempted prior to procedural treatment. Balloon sinuplasty (BSP) is an established procedure for symptomatic relief from chronic rhinosinusitis. However, data suggesting the suboptimal efficacy of prolonged medication management trials, prior to BSP, is lacking. Objectives The purpose of this study was to evaluate the efficacy of prolonged medication management trials, prior to BSP, for patients with chronic rhinosinusitis. Methods A retrospective review was performed for all adults with chronic rhinosinusitis who received extended medical management prior to their BSP at two outpatient clinics, from November 1, 2013, to June 31, 2018. The patients' Sino-Nasal Outcome Test (SNOT) scores were compared between baseline, post-medication trials, and post-BSP. Results The SNOT scores of a total of 64 patients were collected. Overall, patients showed a significant worsening of symptoms during the medication management trials from baseline (p = 0.002126) but significant improvement of symptoms after undergoing BSP (p < 0.0001). Conclusions The patient symptom burden worsened and prolonged during medication management trials. The BSP procedure alone showed significant improvement in the quality of life for chronic rhinosinusitis patients, when considering their SNOT scores. The worsening of patients' symptoms during medication management may invalidate the necessity of prolonged medication management trials.

Perfil de consulta ambulatoria otorrinolaringológica en pandemia por COVID-19 / Profile of patients in otorhinolaryngological consultation in a COVID-19 pandemic

Introducción: La patología otorrinolaringológica (ORL) presenta alta incidencia en atención primaria, alcanzando hasta 49% de las consultas, sin embargo, la pandemia por SARS-CoV-2 repercutió de manera transversal en los servicios sanitarios, pudiendo haber influido en el perfil de consulta, por lo que se requiere un análisis para la elaboración de estrategias que permitan asegurar la atención sanitaria ante eventos de esta magnitud. Objetivo: Analizar el perfil de consulta libre por patología ORL ambulatoria en un centro médico privado en La Serena durante los años 2019 y 2020. Material y Método: Estudio analítico de corte transversal sobre consultas ambulatorias durante los años 2019 y 2020 realizadas en un centro privado de atención abierta en La Serena. Se estimaron frecuencias en números absolutos y proporciones, estimación de promedios y medianas. Resultados: Durante 2019 hubo un total de 11.932 consultas y en 2020 hubo 9.576. Se observó un predominio de sexo femenino en las consultas de 51% en ambos años. La mediana en 2019 fue de 35 años y en 2020 de 39 años. En 2020 las patologías con mayor consulta fueron nariz (44%), oído (37%) y faringolaringe (14%). Existió un aumento significativo en la consulta por patología cocleovestibular durante 2020. Conclusión: En 2020 hubo una disminución del 19,7% de las consultas dado, probablemente, a las restricciones de movilidad y aforos. Existió un aumento significativo en la proporción de consultas por patologías cocleovestibulares, como vértigo periférico, hipoacusia súbita y tinnitus, atribuido probablemente al estrés emocional generado por la pandemia.

Introduction: Otolaryngological (ENT) pathology presents high incidence in primary care reaching up to 49% of morbidity consultations, however, the pandemic by SARS-CoV-2 had a transversal impact on health services, and may have influenced the consultation profile, so an analysis is required for the development of strategies to ensure health care in the face of events of this magnitude. Aim: To analyze the profile of spontaneous consultation for outpatient ENT pathology in a medical center in La Serena city during 2019 and 2020. Material and Methods: Cross-sectional analytical study of outpatient consultations during the years 2019 and 2020 performed in a private open care center in the commune of La Serena. Frequencies were estimated in absolute numbers and proportions; averages and medians were estimated. Results: During 2019 there were a total of 11,932 consultations and in 2020 there were 9,576. There was a predominance of female sex in the consultations of 51%. The median in 2019 was 35 years and in 2020 it was 39 years. In 2020, the pathologies with the highest number of consultations were nose (44%), ear (37%) and laryngopharynx (14%). There was an increase in consultation for cochleovestibular pathology during 2020. Conclusion: In 2020 there was a 19.7% of consultation decrease probably due to mobility and capacity restrictions. There was a significant increase in the proportion of consultations for cochleovestibular pathologies such as peripheral vertigo, hearing loss and tinnitus, probably attributed to the emotional stress generated by the pandemic.

Necrotizing Otitis Externa: A Proposal for Diagnostic and Therapeutic Approach

Abstract Introduction Necrotizing otitis externa has a high impact on the quality of life of patients and has shown a significant increase in its incidence in recent years. There has been a change in the profile of affected patients and a lack of consensus on the management of these patients. Objective To develop a practical and effective care protocol to standardize the diagnostic and therapeutic management of necrotizing otitis externa. Methods A retrospective cohort study of necrotizing otitis externa patients between January 2015 and December 2020. Results There were 34 patients with two bilateral cases, totaling 36 ears. The mean age was 68.5, with a higher prevalence of males (76%). Diabetes was present in 97% of the samples. The involvement of cranial pairs was identified in 35% of the sample. Pseudomonas aeruginosa was the most frequent pathogen isolated, found in 50% of the cases. Among the cultures with bacterial agents isolated, 35% showed resistance to ciprofloxacin. The most frequent exam was computed tomography (94%). Hospital admission was indicated for 31 patients (91%), and ceftazidime was the most prescribed drug (35.5%). There were 11 recurrences (32%), and 12 patients (35%) had complications during treatment. Among the unfavorable outcomes, 12% persisted with some degree of peripheral facial paralysis, 6% maintained dysphagia, and 9% died of the disease. Conclusions The present study developed a diagnostic and therapeutic protocol for the effective management of necrotizing otitis externa. This protocol is a dynamic tool and should be revised and updated as new demands emerge during its implementation.

Application of flipped classroom based on effective teaching theory in clinical teaching of nursing students in otolaryngology and head and neck surgery / 中华医学教育探索杂志

Objective:To investigate the effect of flipped classroom teaching based on effective teaching theory in the clinical teaching of otolaryngology and head and neck surgery.Methods:A total of 35 nursing students who received clinical teaching in Department of Otolaryngology and Head and Neck Surgery, Xinhua Hospital Affiliated to Shanghai Jiao Tong University Medical College, from June 2019 to June 2020 were selected as control group, and 35 nursing students who received clinical teaching from July 2020 to July 2021 were selected as study group. The students in the control group received traditional teaching, and those in the observation group received flipped classroom teaching based on effective teaching theory. The two groups were compared in terms of the scores of theoretical knowledge and practical operation after teaching, abilities of self-learning, analysis and problem-solving, innovative thinking, teamwork, and nurse-patient communication before and after treatment, and the degree of satisfaction with teaching among nursing students. SPSS 24.0 was used to perform the t-test and the chi-square test. Results:After teaching, the study group had significantly higher scores of theoretical knowledge and practical operation than the control group (94.24±3.25/94.65±3.41 vs. 89.54±3.36/88.76±3.37, P < 0.05). After teaching, both groups had significant increases in the scores of self-study ability, analysis and problem-solving ability, innovative thinking ability, teamwork ability, and nurse-patient communication ability, and the study group had significantly higher scores of these abilities than the control group ( P < 0.05). The study group had a significantly higher satisfaction rate of teaching than the control group [94.29% (33/35) vs. 71.43% (25/35)]. Conclusion:In the clinical teaching of nursing students in otolaryngology and head and neck surgery, the application of flipped classroom teaching based on effective teaching theory can improve the understanding of theoretical knowledge and practical operation ability, with significant increases in comprehensive ability and degree of satisfaction with teaching, and therefore, it has a good application value.

A comparison between Different Surgical Approaches of Nasopharyngeal Angiofibroma: A Cross-Sectional Observational Study in BSMMU, Bangladesh

Background: The Otolaryngologist is currently dealing with a dramatic problem the nasopharyngeal angiofibroma. The posterolateral wall of the nasal cavity, close to the superior margin of the sphenopalatine foramen, is where the tumor commonly first appeared.Material & Methods:The Otolaryngology & Head Neck Surgery department at Bangabandhu Shiekh Mujib Medical University, Dhaka Medical College Hospital, and Shaheed Suhrawardy Medical College Hospital in Dhaka undertook this retrospective cross-sectional study. The research was done from February 2012 to November 2012. The study’s overall sample size was 30.Results:The majority of individuals (54%) who have nasopharyngeal angiofibroma are between the ages of 16 and 20. the majority of patients have similar symptoms such epistaxis, nasal blockage, nasal discharge, anemia, and masses in the nasal cavity. At presentation, anaemia is present to various degrees in 90% of cases. The lateral rhinotomy method is employed (40%) more often than other approaches. Three blood units were to be transfused into a maximum of 36.66% of the patients throughout the surgery.Conclusion:Nasopharyngeal angiofibroma is currently a difficult issue for otolaryngologists. When endoscopy was used instead of open techniques, we discovered that the mean length of the procedure was shorter, which may be related to endoscopy’s decreased morbidity.

INTRODUCCIÓN. La patología de oído es una enfermedad frecuente en nuestro medio, asociada a infecciones a repetición del oído, con la presencia de perforación timpánica y colesteatoma, que determinará la presencia de lesiones mucho más acentuadas en cuanto a la evolución auditiva o complicaciones locales o sistémicas. OBJETIVO. Determinar la asociación existente entre la presencia de colesteatoma y perforación timpánica en pacientes con otitis media crónica. MATERIALES Y MÉTODOS. Estudio epidemiológico analítico retrospectivo. Población de 4 733 y muestra de 75 pacientes para casos y 75 para controles basados en historias clínicas tomadas del sistema informático AS 400, que acudieron a la consulta externa de torrinolaringología del Hospital de Especialidades Carlos Andrade Marín en el periodo de enero de 2018 a diciembre de 2019; Criterios de inclusión para grupo de casos: Hombres y mujeres de 20 a 65 años de edad, diagnóstico de otitis media crónica, diagnóstico de colesteatoma ótico. Criterios de inclusión para grupo controles: Hombres y mujeres de 20 a 65 años de edad, no presentar diagnóstico de colesteatoma. RESULTADOS. Se observó una relación fuerte entre el poseer perforación timpánica y el desarrollo de colesteatoma con un valor de OR 33,14 con un IC al 95% de 31,94 ­ 34,34, con lo que se comprobó la hipótesis del estudio. Se determinó que la perforación timpánica es un factor de riesgo asociado con el desarrollo de colesteatoma en pacientes con otitis media crónica, la prevalencia de colesteatoma en relación a la edad estuvo en un 72% en pacientes de 41 a 65 años, con mayor predominancia en mujeres en un 57,3%. DISCUSIÓN. La presencia de perforación timpánica de acuerdo a lo observado es un factor de riesgo para el desarrollo de colesteatoma, ligado en su mayoría a cuadros de Otitis Media Crónica. CONCLUSIONES. Se confirmó que la perforación timpánica, es un factor de riesgo en el desarrollo del colesteatoma en los pacientes que tienen otitis media crónica, lo que demuestra la necesidad de manejo actualizado y continuo en pacientes con esta patología de oído. Se requieren estudios con muestras más amplias para determinar otros factores de riesgo como sexo, nivel de educación y edad que podrían influir en el desarrollo de colesteatoma.

INTRODUCTION. Ear pathology is a frequent disease in our environment, associated with repeated ear infections, with the presence of tympanic perforation and cholesteatoma, which will determine the presence of much more accentuated lesions in terms of auditory evolution or local or systemic complications. OBJECTIVE. To determine the association between the presence of cholesteatoma and tympanic perforation in patients with chronic otitis media. MATERIALS AND METHODS. Retrospective analytical epidemiological study. Population of 4 733 and sample of 75 patients for cases and 75 for controls based on clinical histories taken from the AS 400 computer system, who attended the Otorhinolaryngology outpatient clinic of the Carlos Andrade Marín Specialties Hospital in the period from January 2018 to December 2019; Inclusion criteria for case group: Men and women aged 20 to 65 years, diagnosis of chronic otitis media, diagnosis of otic cholesteatoma. Inclusion criteria for controls group: men and women aged 20 to 65 years, no diagnosis of cholesteatoma. RESULTS. A strong relationship was observed between having tympanic perforation and the development of cholesteatoma with an OR value of 33,14 with a 95% CI of 31,94 - 34,34, thus proving the study hypothesis. It was determined that tympanic perforation is a risk factor associated with the development of cholesteatoma in patients with chronic otitis media, the prevalence of cholesteatoma in relation to age was 72% in patients aged 41 to 65 years, with greater predominance in women in 57,3%. DISCUSSION. The presence of tympanic perforation according to what was observed is a risk factor for the development of cholesteatoma, mostly linked to Chronic Otitis Media. CONCLUSIONS. It was confirmed that tympanic perforation is a risk factor in the development of cholesteatoma in patients with chronic otitis media, which demonstrates the need for updated and continuous management in patients with this ear pathology. Studies with larger samples are required to determine other risk factors such as sex, education level and age that could influence the development of cholesteatoma.

Self-medication practices with conventional and herbal drugs among ear, nose, and throat patients

SUMMARY OBJECTIVE: This study evaluates the self-practices with conventional and herbal drug use among ear, nose, and throat outpatients. METHODS: A cross-sectional survey-based study was carried out among all ear, nose, and throat outpatients on their first visit to the otorhinolaryngology department at a tertiary care hospital. The survey comprised a total of 14 questions with 4 different sections, including demographic characteristics, self-medication of conventional medicines, herbal medication usage, and perception regarding herbal medicines. RESULTS: Overall, 255 questionnaires were distributed among patients, of which 183 completed the questionnaire (response rate=71.7%). Respondents reported self-medication (44.8%) with conventional drugs before visiting a hospital. The most commonly used medicine was analgesics (31.7%) and antibiotics (21.9%). Nearly half of the patients (49.2%) used at least one herbal drug. The most commonly used herbal medications were Tilia cordata (78.8%), Zingiber officinale (62.2%), and Camellia sinensis (45.5%). According to the International Union for Conservation of Nature Red List, most of the medicinal herbs were considered as data deficient/least concern. About 36.6% of the participants perceived that herbal drugs are effective for ear, nose, and throat problems. Moreover, 22.9% of the patients did not know about herbal-drug interaction with other medications. CONCLUSIONS: This study observed a considerable prevalence of self-based practices with conventional and herbal medications. Strict national regulations on conventional and herbal medication access and long-term actions should be implemented to discourage inappropriate drug use.

The Impact of COVID-19 on the Daily Life and Medical Practice of Otolaryngology Physicians

Abstract Introduction The coronavirus disease 2019 (COVID-19) has made otolaryngologists more susceptible than their counterparts to its effect. Objective This study aimed to find if COVID-19 had a different impact on ear, nose, and throat (ENT) physicians' of various categories (residents, registrars, and consultants ) regarding many aspects of the quality of life (protection, training, financial, and psychological aspects). Methods We included 375 ENT physicians, of different categories (residents, registrars, and consultants), from 33 general hospitals and 26 university hospitals in Egypt. The study was conducted using a 20-item questionnaire with a response scale consisting of three categories: yes, no, and not sure. It covered infection control and personal protective equipment (PPE) usage; medical practice and safety; online consultation and telemedicine,; webinars and online lectures; COVID-19 psychological, financial, and quarantine period effects; and future expectations. Results The results of the questionnaire showed that COVID-19 had a statistically significant impact on the daily life of the responders. There were statistically significant differences among the three involved categories, based on their answers. Conclusion This study showed a statistically significant difference regarding the impact of COVID-19 on many aspects of the quality of life (protection, training, financial, and psychological aspects) of ENT physicians of various categories (residents, registrars, and consultants), and these effects may persist for a long time.

Efecto placebo en otorrinolaringología: revisión de la literatura / Placebo effect in otorhinolaryngology: a narrative review

Resumen La palabra placebo ha sido usada, indistintamente, para referir a una sustancia o procedimiento que es "inerte" ("placebo") y al efecto que ocurre como consecuencia de la administración de un placebo ("efecto placebo"). El efecto placebo es un fenómeno psicobiológico que ha sido explicado desde el conductismo (condicionamiento clásico), desde fenómenos preconscientes (expectativas o "efecto placebo clásico"), desde el cognitivismo (disonancia cognitiva) y también a nivel neurobiológico. No obstante, los ensayos clínicos abiertos que verifican la respuesta a placebo desafían el mecanismo de la expectativa, dando lugar al análisis bayesiano, que integra sensaciones, experiencias, predicciones y claves del contexto; biológicamente, el efecto placebo no es inerte. Por tanto, el placebo ocupa un lugar relevante en la práctica clínica y en la investigación biomédica. Se realizó una búsqueda sistemática sobre placebo y otorrinolaringología en las bases de datos PubMed/Medline, SciELO y Cochrane Library. Se incluyeron estudios primarios y revisiones sistemáticas de la literatura. En cuanto a intervenciones placebo, la literatura publicada indica mejorías significativas en síntomas nasales y calidad de vida en rinitis alérgica (estacional y perenne) y disminución del dolor posoperatorio en amigdalectomía. En la enfermedad de Méniere, las intervenciones placebo son comparables a las de uso habitual, incluyendo las quirúrgicas. No se encontraron ensayos clínicos abiertos en otorrinolaringología ni evidencia sobre otras patologías del área. Las intervenciones y el efecto placebo abren un campo de investigación y desarrollo en otorrinolaringología que desafía la comprensión actual de las patologías, su funcionamiento, su tratamiento y la relación terapéutica.

Abstract The word placebo has been used interchangeably to refer to a substance or procedure that is "inert" ("placebo") and the effect that occurs as a consequence of its administration ("placebo effect"). The placebo effect corresponds to a psychobiological phenomenon that has been explained from behaviorism (classical conditioning), from preconscious phenomena (expectations or "classical placebo effect"), from cognitivism (cognitive dissonance) and at the neurobiological level as well. Nevertheless, some open-label trials that verify the response to placebo challenge the expectation mechanism, giving rise to Bayesian analysis, which integrates sensations, experiences, predictions and context clues; therefore, biologically, the placebo effect is not inert. The placebo has a relevant place both in clinical practice and in biomedical research. We conducted a systematic search on placebo and otolaryngology in PubMed/Medline, SciELO and Cochrane Library databases. We included primary studies and systematic reviews. Regarding placebo interventions, the available literature points out significant improvements in nasal symptoms and quality of life in allergic rhinitis (seasonal and perennial) and a decrease in post-tonsillectomy pain. In Méniére's disease, placebo interventions have demonstrated to be comparable to treatment-as-usual, including surgical interventions. No open-label clinical trials were found in otolaryngology, as well as no evidence on other diseases in the area. Placebo interventions and their effects open a field of research and development in otolaryngology, challenging the current understanding of pathologies, their functioning, their treatment and the therapeutic relationship.

Cochlear implant complications in a low-income area of Brazil

SUMMARY OBJECTIVE: The primary objective was to analyze and report on the complications that occurred in the cochlear implant surgeries performed at a large philanthropic teaching hospital located in a low-income area of Brazil. METHODS: A historical cohort study that analyzed surgical records of 432 patients of all age groups and both genders who received unilateral cochlear implant in a tertiary referral center that serves only Brazil's Public Health Care System patients, from February 2009 to December 2017. RESULTS: A total of 67 (15.5%) complications occurred in the cochlear implant surgeries, with 21 (5.4%) major complications. Minor complications occurred in 50 (12%) cases. The most frequent major complication was receiver-stimulator displacement (four cases). There were three cases of hardware failure. Only one case of meningitis and one case of facial nerve paralysis (grade VI in House-Brackmann scale) were found. Six patients needed to be explanted due to a major complication. The relative risk of major complications in the population aged 60 years and older was 4.41 (1.53-12.72; 95% confidence interval [CI]). CONCLUSIONS: Elderly patients suffered more complications than younger patients. receiver-stimulator displacement and dizziness were the most frequent complications (major and minor, respectively). The overall complication rates were comparable to those in the literature. Age as an isolated risk factor for complications in cochlear implant surgery is a path to be explored in future observations.

Cuerpos extraños en otorrinolaringología: Experiencia en Clínica Santa María / Foreign bodies in otolaryngology: Experience at Clínica Santa María

Resumen Introducción: Los cuerpos extraños (CE) en oído, nariz y vía aéreodigestiva superior son el 30% de las urgencia en otorrinolaringología (ORL). No existen datos epidemiológicos nacionales que describan la casuística de CE. Objetivo: Describir la epidemiología de pacientes con diagnóstico de CE evaluados, entre el 2013-2018 en Clínica Santa María de Santiago, Chile. Describir las características de los CE, ubicación, método de extracción y complicaciones. Material y Método: Estudio descriptivo y retrospectivo, basado en revisión de fichas clínicas de pacientes con diagnóstico de CE, analizando variables epidemiológicas y clínicas. Resultados: Se revisaron 1.847 casos con diagnóstico de CE, confirmando 1.494. La mayoría de sexo masculino (53,3%), con un promedio de edad de 16,5 años (rango de 0-95 años). Los CE más prevalentes fueron ótico (52,9%) y nasal (27,9%). El síntoma asociado más frecuente fue la sensación de CE (18,1%). El diagnóstico fue principalmente por examen físico (84%), requiriéndose exámenes complementarios en 18,2%. La extracción fue ambulatoria en su mayoría (84,6%), requiriendo extracción en pabellón el 12,5%. El 5,5% presentó complicaciones, y la tasa de letalidad fue de 0,07%. Conclusión: Esta casuística, única a nivel nacional, nos permite conocer la epidemiología de los CE. Un bajo porcentaje de pacientes fue de riesgo vital, pero el manejo oportuno permite una baja tasa de complicaciones y letalidad.

Abstract Introduction: Foreign bodies (FB) in the ear, nose and upper airway-digestive tract are 30% of the emergencies in otolaryngology (ORL). There is no national epidemiological data that describes the FB casuistry. Aim: To describe the epidemiology of patients who have a diagnosis of a FB evaluated, between 2013-2018, at Santa María Clinic in Santiago, Chile. To describe the characteristics of FB, location, method of removal, and complications. Material and Method: A descriptive and retrospective study, based on review of clinical records of patients with the diagnosis of FB, analyzing epidemiological and clinical variables. Results: 1847 cases with a diagnosis of FB were reviewed, of which 1494 were confirmed. Most were male (53.3%), with an average age of 16.5 years (range 0-95 years). The most prevalent FB locations were otic (52.9%) and nasal (27.9%). The most frequent associated symptom was sensation of a FB (18.1%). The diagnosis was fundamentally based on physical examination (84%), requiring complementary tools in 18.2%. The extraction was mostly ambulatory (84.6%), requiring extraction in the operation room in 12.5%. 5.5% presented complications, and the fatality rate was 0.07%. Conclusion: This casuistry is unique at the national level, and allows us to know the epidemiology of FB. A low percentage of patients correspond to life-threatening locations, but timely management allows a low rate of complications and fatality.

Biobancos en otorrinolaringología / Biobanks in otolaryngology

Resumen Los biobancos son una innovadora herramienta biotecnológica y un recurso fundamental para el continuo avance en la investigación científica biomédica, y para el advenimiento de la medicina de precisión. Se han desarrollado de forma exponencial durante los últimos 20 años en el mundo, como también a nivel de nuestro país, con la creación de 10 biobancos desde el año 2004. En ellos se almacenan y organizan distintos tipos de muestras biológicas, asociadas a datos epidemiológicos y genéticos de donantes voluntarios. Todos los especímenes almacenados deben ser preservados con estándares de calidad garantizados, a modo de asegurar trazabilidad, integridad y calidad de las muestras. A pesar de que la mantención de un biobanco puede significar altos costos, a fin de cuentas, abaratan costos de los estudios clínicos, dado que es precisamente el biobanco quien se encarga de la obtención de datos y muestras clínicas confiables, permitiendo realizar múltiples estudios a partir de las mismas muestras. A través de este proceso, los biobancos permiten mantener una fuente confiable de recur-sos para la investigación en diversas áreas de la medicina, dentro de ellas la otorrinolaringología. En otorrinolaringología, los biobancos han significado un gran avance, facilitando la investigación en relación con hipoacusia, presbiacusia y tinnitus, así como en el área oncológica. En un futuro, se espera que la comunidad científica haga uso de este recurso, pudiendo expandir su utilidad no solo en el área médica, sino también en otras profesiones de la salud, maximizando así su gigantesco potencial.

Abstract Biobanks are novel biotechnological tools and a fundamental resource for the constant development of biomedical research, as much as for the growing practice of precision medicine. They have proliferated worldwide over the past 20 years and Chile has not been left behind with the creation of 10 bio-banks since 2004. Biobanks store and organize different types of biological samples associated with epidemiological and genetic data from volunteer donors. These samples are stored and preserved under guaranteed quality standards to ensure their traceability, integrity, and quality. Even though the price of maintaining a biobank may seem high, after all, they reduce the costs of research, since biobanks are responsible of the acquisition and storage of data and samples, allowing the performance of multiple studies from the same collection of specimens. In this direction, biobanks grant a constant source of well-founded scientific material for investigation in a wide range of medical fields, such as otolaryngology among them. In otolaryngology, the biobanks have meant a great improvement, facilitating investigations related to deafness, presbycusis, tinnitus and oncology. In the future we hope the scientific community will expand the use this innovative tool over a broader medical field and towards other health-related professions, making the most of its enormous potential.

Mediastinitis descendente en el contexto de la angina de Ludwig. Artículo de revisión / Descending mediastinitis in the context of Ludwig's Angina. Article review

Introducción: la mediastinitis se define como el proceso inflamatorio usualmente infeccioso del tejido conectivo mediastinal y los órganos que este rodea. Específicamente, la mediastinitis descendente corresponde a una complicación rara por infección de los espacios profundos del cuello, la orofaringe o la cavidad oral, que se extiende a través de los espacios fasciales del cuello y los diseca. De forma infrecuente, esta patología puede originarse a partir de la parotiditis, las infecciones de la piel del cuello o la epiglotitis. También, de manera menos frecuente, puede generarse en el contexto de un traumatismo del cuello o la cavidad oral. En este estudio se pretende llamar la atención, en particular, sobre los aspectos que involucran al especialista otorrinolaringólogo en el manejo de los pacientes con infecciones profundas del cuello y su rol en el diagnóstico y tratamiento eficaz de la mediastinitis descendente, como la principal causa de mortalidad en estos casos. Metodología: se llevó a cabo una búsqueda con las palabras clave "Airway" "Ludwig's angina" en PubMed, no se efectuó filtración por fecha ni tipo de estudio. Se encontró un total de 147 artículos. Se realizó lectura de los resúmenes por los autores y se seleccionaron 50. Se realizó lectura crítica del texto completo de los 50 artículos resultantes de la búsqueda y se extrajo la información relevante. Conclusión: esta patología de marcada severidad conlleva a un aumento significativo de la mortalidad. Su tratamiento, aunque permanece controversial en ciertas circunstancias, debe ser agresivo y oportuno, con un enfoque en el rol del otorrinolaringólogo en 4 pilares de tratamiento: el drenaje quirúrgico, la antibioticoterapia de amplio espectro, el soporte hemodinámico y la seguridad de la vía aérea.

Introduction: Mediastinitis is defined as the usually infectious inflammatory process of the mediastinal connective tissue and the organs it surrounds. Specifically, descending mediastinitis corresponds to a rare complication, an infection of deep spaces of the neck, oropharynx, or oral cavity, which extends through the facial spaces of the neck, dissecting. Less frequent, this pathology can originate from parotiditis, skin infections of the neck or epiglottitis. Also, less frequent it can be generated in the context of trauma to the neck or oral cavity. This study intends to draw attention to the aspects that involve the ENT specialist in the management of patients with deep neck infections and their role in the diagnosis and effective treatment of descending mediastinitis as the main cause of mortality in these patients. Methodology: A search was carried out with the keywords "Airway" "Ludwig's angina" in PubMed, no filtering was performed by date or type of study, finding a total of 147 articles, abstracts were read by the authors, selecting 50. A critical reading of the 50 articles full texts is carried out and the relevant information is extracted. Conclusion: This pathology of marked severity, carries a significant increase in mortality and its treatment, although it remains controversial in certain circumstances, it must be aggressive and timely, focusing the role of the otorhinolaryngologist on 4 pillars of treatment: surgical drainage, antibiotic therapy, hemodynamic support, and airway safety.
