Diagnostic accuracy of the video otoscope in tympanic membrane perforation.

OBJECTIVE: The video otoscope has already proven to be useful for the diagnosis of several pathologies, so the objective of this study was to evaluate the diagnostic accuracy of the video otoscope in cases of tympanic membrane perforation. METHODS: This is a diagnostic accuracy study performed at the hearing health division of a tertiary-level referral hospital. Patients older than 8 years of age who had any symptom that could be related to perforation (otalgia, otorrhea, tinnitus, and/or hypoacusis) were invited to participate in the study. Participants were evaluated by three different diagnostic methods (otomicroscope, conventional otoscope, and video otoscope) performed by three different evaluators in a blind fashion. The microscope was considered the reference standard. RESULTS: 176 patients were evaluated, totaling 352 tympanic membranes. Twenty-seven tympanic membrane perforations were diagnosed by the microscope, a prevalence of 7.7%. The video otoscope showed a sensitivity of 85.2% (95% CI 81.5%‒88.9%), specificity of 98.1% (95% CI 96.7%‒99.5%) and accuracy of 97.1% (95% CI 95.4 %-98.8 %). The conventional otoscope showed a sensitivity of 96.3% (95% CI 94.3-98.3), specificity of 98.8% (95% CI 97.7-99.9) and accuracy of 98.6% (95% CI 97.4-99.8). The Kappa value between the microscope and the video otoscope was 0.8 and between the microscope and the conventional otoscope was 0.9. Regarding the participants' perception, 53.4% (p< 0.001) considered the video otoscope as the best method for understanding the tympanic membrane condition presented by them. CONCLUSIONS: The video otoscope showed relevant sensitivity and specificity for clinical practice in the diagnosis of tympanic membrane perforation. Moreover, this is an equipment that can facilitate the patient's understanding of the otologic pathology presented by him/her. In this regard, this method may be important for better patient compliance, requiring further studies to evaluate this hypothesis. LEVEL OF EVIDENCE: Is this diagnostic or monitoring test accurate? (Diagnosis)-Level 2 (Individual cross-sectional studies with consistently applied reference standard and blinding).

Tonsils are major sites of persistence of SARS-CoV-2 in children.

In the present study, we show that SARS-CoV-2 can infect palatine tonsils, adenoids, and secretions in children without symptoms of COVID-19, with no history of recent upper airway infection. We studied 48 children undergoing tonsillectomy due to snoring/OSA or recurrent tonsillitis between October 2020 and September 2021. Nasal cytobrushes, nasal washes, and tonsillar tissue fragments obtained at surgery were tested by RT-qPCR, immunohistochemistry (IHC), flow cytometry, and neutralization assay. We detected the presence of SARS-CoV-2 in at least one specimen tested in 27% of patients. IHC revealed the presence of the viral nucleoprotein in epithelial surface and in lymphoid cells in both extrafollicular and follicular regions, in adenoids and palatine tonsils. Also, IHC for the SARS-CoV-2 non-structural protein NSP-16 indicated the presence of viral replication in 53.8% of the SARS-CoV-2-infected tissues. Flow cytometry showed that CD20+ B lymphocytes were the most infected phenotypes, followed by CD4+ lymphocytes and CD123 dendritic cells, CD8+ T lymphocytes, and CD14+ macrophages. Additionally, IF indicated that infected tonsillar tissues had increased expression of ACE2 and TMPRSS2. NGS sequencing demonstrated the presence of different SARS-CoV-2 variants in tonsils from different tissues. SARS-CoV-2 antigen detection was not restricted to tonsils but was also detected in nasal cells from the olfactory region. Palatine tonsils and adenoids are sites of prolonged RNA presence by SARS-CoV-2 in children, even without COVID-19 symptoms. IMPORTANCE This study shows that SRS-CoV-2 of different lineages can infect tonsils and adenoids in one quarter of children undergoing tonsillectomy. These findings bring advancement to the area of SARS-CoV-2 pathogenesis, by showing that tonsils may be sites of prolonged infection, even without evidence of recent COVID-19 symptoms. SARS-CoV-2 infection of B and T lymphocytes, macrophages, and dendritic cells may interfere with the mounting of immune responses in these secondary lymphoid organs. Moreover, the shedding of SARS-CoV-2 RNA in respiratory secretions from silently infected children raises concern about possible diagnostic confusion in the presence of symptoms of acute respiratory infections caused by other etiologies.

No association was found between consultation or surgery of patients with COVID-19 and infection of medical personnel.

El buceo recreativo y la otorrinolaringología: ¿qué sabemos y deberíamos saber? / Recreational diving and otolaryngology: what do we know and should we know?

El buceo recreativo es una práctica cada vez más popular en la población mundial, sin embargo, no está exenta de riesgos. A medida que transcurre una inmersión, el buzo es susceptible a una serie de cambios de presión que afectan las distintas cavidades que contienen aire dentro del cuerpo humano, tales como el oído, cavidades paranasales y los pulmones. Existe un gran espectro de patologías asociadas al buceo, explicándose la mayoría de ellas por el barotrauma asociado, cuya gravedad depende de la magnitud del daño asociado, pudiendo presentar desde manifestaciones a nivel local, así como también a nivel sistémico. Las patologías otológicas suelen ser las más frecuentes y el principal motivo de consulta en este tipo de pacientes. Sin embargo, las afecciones otoneurológicas, rinosinusales, de vía aérea y sistémicas pueden ser comunes dependiendo de cada perfil de buceo. Actualmente no existen recomendaciones locales sobre esta práctica, por lo que el conocimiento de la fisiología, fisiopatología y el tratamiento de las patologías otorrinolaringológicas asociadas deben ser conocidas a medida que este deporte se vuelve cada vez más popular. Se realizó una revisión de la literatura sobre las distintas afecciones otorrinolaringológicas con el fin de sistematizarlas y elaborar recomendaciones para establecer una práctica segura.

Recreational diving is an increasingly popular practice in the world; however, it is not without risks. As a dive progresses, the diver is susceptible to a series of pressure changes that affect the air-containing cavities, such as the ear, paranasal cavities, and lungs. There is a large spectrum of pathologies associated with diving, most of them being explained by associated barotrauma, the severity of which depends on the magnitude of the associated damage, could present local manifestations, as well as at systemic level. Otological pathologies are usually the most frequent and the main reason for consultation in this type of patients, however, otoneurological, rhinosinusal, airway and systemic conditions can be common depending on each diving profile. Currently there are no local recommendations on this practice, therefore, knowledge of the physiology, pathophysiology and treatment of associated otorhinolaryngological pathologies should be known as this sport becomes increasingly popular. A review of the literature on the different ear, nose and throat conditions was carried out in order to systematize them and develop recommendations to establish a safe practice.

Trastorno del procesamiento sensorial. Una mirada conjunta desde la terapia ocupacional y la otorrinolaringología / Sensory processing disorder. A vision statement from occupational therapy and otolaryngology

Resumen El trastorno del procesamiento sensorial (TPS) es una condición frecuente, pero poco conocida por muchos profesionales de la salud. El procesamiento sensorial se define como la capacidad que posee el sistema nervioso central de interpretar y organizar las sensaciones del propio cuerpo y del ambiente, para su uso efectivo en el entorno mediante respuestas adaptativas. Por lo tanto, cualquier disfunción en el procesamiento (registro, modulación y/o discriminación) de estos estímulos se expresa como una respuesta desadaptativa, siendo significativo cuando esta impacta en la vida diaria del paciente. Es deber del médico sospechar este trastorno, acogiendo al paciente y su familia, derivando oportunamente a terapia ocupacional para su correcta evaluación y eventual manejo de acuerdo con las necesidades de cada paciente.

Abstract Sensory processing disorder (SPD) is an unknown condition for many health care professionals. Sensory processing is defined as the capacity of the central nervous system to interpretate and organize sensations from our own body and from the environment, for their proper use by adaptive responses. Any dysfunction in this processing (registration, modulation and or discrimination) is expressed by a maladaptive response, being considered abnormal when this response has a negative impact in the patient's daily activities. Is our duty as health care workers to suspect this disorder, help our patients and their families by doing a proper referral to an occupational therapist for their evaluation and management, according to each patient needs.

Ear, Nose, and Throat Practice Guidelines: An Update for COVID-19.

Introduction Amidst another wave of COVID-19, the alarming number of cases per day in India has affected the healthcare system and professionals tremendously. As the disease burden continues to increase, ear, nose, and throat (ENT) specialists remain at high risk of exposure to this aerosol borne virus. This requires the creation and regulation of protocols for conducting routine clinical practice, especially by ENT specialists. Objectives To review the available literature and to propose strategies and recommendations for ENT practitioners to conduct their regular practice amidst this pandemic. Data synthesis A systematic review of the available literature on ENT practice during the COVID-19 pandemic was done. Out of the many protocols proposed in various studies, the most practical and feasible ones that could be adopted by practicing ENT doctors/ surgeons in the long run were selected. Adequate precautions and use of high level of personal protective equipment (PPE) is required to be adopted by all practicing ENT doctors. Use of teleconsultation has been promoted as it limits face-to-face exposure. Proper guidelines should be followed for both emergency and elective surgeries. Endoscopy can be used as a safe and useful tool for ENT examination. Conclusion As practicing otorhinolaryngologists, it is of utmost importance that we take all necessary precautions and adopt safety measures in our clinical practice while conducting out patient department (OPD) consultations, operative procedures, and emergency care to protect our patients, ourselves, and other healthcare staff during this time.

Analysis of Ear, Nose and Throat Manifestations in COVID-19 Patients.

Introduction Coronavirus disease 2019 (COVID-19) has dramatically spread all over the world, crossing the borders of all countries. It is presented mainly by lower respiratory tract symptoms such as fever, cough, dyspnea, and chest tightness. However, COVID-19 causes different upper respiratory tract-related symptoms including nasal congestion, sore throat, and olfactory dysfunction. Objective To discuss different ear, nose and throat (ENT) manifestations in COVID-19-positive patients and their relation to other manifestations and to the severity of COVID-19. Methods We detected ENT manifestations in polymerase chain reaction (PCR)-confirmed positive COVID-19 patients at Zagazig Isolation Hospitals (Zagazig University hospitals, Zagazig Chest hospital, Al-Ahrar hospital, and Zagazig Fever hospital) with proportional allocation in the period from April 15 to June 15, 2020. All patients were subjected to full history taking and COVID-19 was categorized into 4 classes of severity after all patients underwent computed tomography (CT) of the chest. Afterwards, the collected data was analyzed and compared. Results Among the included 120 COVID-19 patients, the most frequent reported ENT manifestations were; sore throat (30%), nasal congestion (28.3%), nasal obstruction (26.7%), sneezing (26.6%), headache (25%), smell and taste dysfunction (25%), rhinorrhea (20%), upper respiratory tract infection (URTI) (15%), and tonsil enlargement (10%). The most common non-ENT manifestations were fever (88.3%), cough (63.3%), and dyspnea (45%). Conclusion Fever and cough are the dominant symptoms of COVID-19, but ENT manifestations for COVID-19 are common and should be a part of the suspected clinical criteria for COVID-19, particularly if the nasal examination was nonsignificant. The most common symptoms are sore throat, followed by nasal congestion and obstruction, headache, and lastly, olfactory dysfunction.

Hearing Loss in Mucopolysaccharidosis.

Introduction Mucopolysaccharidosis (MPS) is a set of rare diseases caused by deficiency of lysosomal enzymes that lead to the accumulation of glycosaminoglycans (GAG) in tissues and organs, which, in turn, is responsible for the multisystemic clinical, chronic, and progressive symptoms. Objective To describe the profile of the otorhinolaryngological clinical examination and audiology tests of patients with MPS disease. Methods The present study is a case series. The evaluation was performed, initially, in 24 patients with MPS types I, II, IIIA, IV and VI. Results The most common hearing complaint was hearing loss, which was confirmed by audiology tests in almost 100% of the patients, most of whom presented conductive hearing loss. Conclusions It is important to evaluate the complaints, physical examination, and audiology tests in patients with MPS. The otorhinolaryngologistshould be part of the group of professionals that follows these patients to better monitor their hearing and provide early hearing rehabilitation.

Manifestaciones otorrinolaringológicas en la infección por virus de inmunodeficiencia humana

Resumen La infección por el virus de la inmunodeficiencia humana (VIH) es una pandemia global que afecta a 38 millones de personas en el mundo. En Chile, se ha visto un alza sostenida en la incidencia de VIH, aumentando un 57% entre 2010 y 2019, reportándose 74.000 personas que viven con VIH en el país. Las manifestaciones en cabeza y cuello ascienden a un 80% de los pacientes con VIH. Éstas pueden presentarse durante el síndrome retroviral agudo, en etapas más avanzadas, incluso como forma de debut, o aparecer en casos de falla de tratamiento o complicaciones derivadas del síndrome inflamatorio de reconstitución inmune. Con la mayor cobertura de terapia antirretroviral (TARV) se ha visto a lo largo del tiempo un cambio en la frecuencia de las manifestaciones otorrinolaringológicas. Las lesiones de la cavidad oral han representado un signo de avance de la enfermedad o de falla al tratamiento, siendo más frecuentes la candidiasis y la leucoplasia vellosa. En el área rinosinusal predominan la rinitis y rinosinusitis, en el cuello las linfadenopatías e hipertrofia parotídea, y en el oído la hipoacusia, alteraciones vestibulares y del oído medio. Para la especialidad de otorrinolaringología es fundamental conocer estas manifestaciones para mantener un alto índice de sospecha del diagnóstico. De esta forma, se permite un diagnóstico precoz y tratamiento oportuno para así mejorar la calidad de vida del paciente. Además, se requiere un seguimiento cercano de forma de detectar signos tempranos de falla al tratamiento o progresión a etapas más avanzadas.

Abstract The human immunodeficiency virus (HIV) infection is a global pandemic, affecting 38 million people worldwide. In Chile, its incidence has risen continuously, increasing to 57% from 2010 to 2019, with 74,000 infected people in the country. Head and neck manifestations account to 80% of HIV patients. These manifestations may be present during the acute retroviral syndrome, in more advanced stages, even as a debut, or appear in treatment failure or complications secondary to the immune reconstitution inflammatory syndrome. With the increase in antiretroviral therapy (ART) coverage, the prevalence of otorhinolaryngological manifestations has changed. Oral lesions may be an early sign for advanced stages or treatment failure, with a predominance of candidiasis and hairy leukoplakia. Rhinitis and rhinosinusitis are the main manifestations in the sinonasal area, lymphadenopathy and parotid hypertrophy in the neck, and hearing loss, vestibular and middle ear disorders in the ear. It is essential for otorhinolaryngologists to be aware of these manifestations in order to maintain a high index of clinical suspicion, allowing an early diagnosis and opportune treatment to improve the patient's quality of life. In addition, a close follow-up is required to identify early signs of treatment failure or progression to more advanced stages.

Bruxismo y su relación con otorrinolaringología: una revisión de la literatura

Resumen El bruxismo es una condición que se observa frecuentemente en los pacientes y estos a menudo consultan por sus consecuencias físicas, como pueden ser el desgaste o destrucción dentaria, el dolor orofacial, así como también por el deterioro de la calidad de vida tanto de ellos mismos como de las personas cercanas. En la última década han aumentado en forma importante las investigaciones en torno a esta condición, así como los consensos en cuanto a su definición, clasificación y manejo clínico. Los dentistas son quienes actualmente reconocen esta actividad parafuncional y manejan estos problemas, pero es importante que los profesionales de otras áreas de la salud, como médicos y en especial otorrinolaringólogos, puedan identificar los signos, síntomas y consecuencias del bruxismo, ayudando en la detección de esta condición. Así, el objetivo de esta revisión es establecer un estado del arte sobre bruxismo e incentivar la formación de equipos multidisciplinares que ayuden en el diagnóstico y la terapéutica de esta condición.

Abstract Bruxism is a condition that is frequently observed in patients, and they often consult for physical consequences, such as teeth wear or destruction, orofacial pain, as well as for the decrease of the quality of life, of both patients and their loved ones. In the last decade, research on this phenomenon has increased significantly, as well as the consensus in terms of definition, classification and clinical management. Dentists are those who at present recognize this parafunctional activity and manage these problems, but it is important that professionals from other health areas, such as medical doctors, and specially otolaryngologists, can identify signs, symptoms and consequences of bruxism, helping in the detection of this condition. Thus, the objective of this review is to establish a state of the art about bruxism and encourage the formation of multidisciplinary teams that help to in the diagnosis and better management of this condition.

Neonatal nasal obstruction.

PURPOSE: Congenital nasal obstruction can be a significant cause of respiratory distress in the newborn, given that they are considered to be obligate nasal breathers. Several different causes have been described, which can be broadly classified as anatomical/malformative, non-tumoral masses and cysts, benign and malignant neoplasia, inflammatory/infectious, traumatic/iatrogenic, and miscellaneous. The purpose of this review is to provide updated and useful clinical information for teams involved in neonatal care, especially in a hospital setting. METHODS: A review of the available literature was performed. Studies were sourced from PubMed with searching of relevant headings and sub-headings and cross-referencing. RESULTS: The most common etiology is inflammatory, which can have different precipitating factors or be idiopathic, a condition known as neonatal rhinitis. On the other hand, some less frequent but nonetheless relevant conditions causing severe nasal obstruction include choanal atresia, midnasal stenosis, and pyriform aperture stenosis. Some cystic lesions, such as dacryocystoceles with intranasal mucocele, can also produce significant obstruction. Diagnosis usually requires a nasal endoscopy and in some cases imaging such as computed tomography. Management includes different medical and surgical strategies and will greatly depend on the etiology and the severity of symptoms. CONCLUSION: Congenital nasal obstruction can be a significant cause of respiratory distress in the newborn. The wide spectrum of differential diagnoses requires a thorough knowledge of nasal anatomy, physiology, and pathology; as well as different management strategies.

Construção de consenso Delphi das competências otorrinolaringológicas preconizadas ao egresso de Medicina / Building a Delphi consensus on Otorhinolaryngological skills for the medical graduate

Resumo: Introdução: Afecções otorrinolaringológicas são destaques entre as enfermidades mais frequentes na atenção primária. Acredita-se que a sobrecarga na atenção secundária seja consequência da baixa resolução dos problemas na atenção primária. Uma possível explicação para esse fato seria a deficiência na capacitação médica durante a graduação. Estima-se que a carga horária média de otorrinolaringologia seja 0,6% da carga horaria média total, após análise de 141 matrizes curriculares, correspondendo a aproximadamente 70,5% do total das escolas médicas em funcionamento em 2013. Nessa área, poucos estudos têm sido realizados em relação ao ensino e à necessidade de reavaliação curricular. Objetivo: O presente estudo tem o intuito de buscar um consenso sobre as competências necessárias ao generalista na especialidade de otorrinolaringologia. Métodos: Criou-se um questionário inicial que abordava as competências otorrinolaringológicas pertinentes à prática clínica dos médicos da atenção primária. Por meio da metodologia Delphi, no formato eletrônico, o questionário foi enviado para 20 especialistas com formações distintas: médicos generalistas, otorrinolaringologistas e médicos de família e comunidade. Essa heterogeneidade entre os especialistas contribuiu para garantir a confiabilidade dos resultados. Os resultados obtidos após cada rodada eram analisados pelos pesquisadores, que observavam as tendências e as opiniões dissonantes, bem como suas justificativas. Ao final da sistematização e compilação dos resultados, um novo questionário era elaborado e reenviado, iniciando uma nova rodada até que o consenso fosse estabelecido em todas competências. Resultados: Realizaram-se cinco rodadas para o estabelecimento do consenso em todas as 17 competências otorrinolaringológicas avaliadas pelas proposições, o possibilitou a definição do nível de competência dos conteúdos e procedimentos otorrinolaringológicos preconizados ao egresso de Medicina. Conclusão: Os dados obtidos neste trabalho podem servir para o embasamento, direcionamento e desenvolvimento do currículo otorrinolaringológico nos cursos de graduação de Medicina, visto que não se encontrou na literatura consenso estabelecendo as competências mínimas otorrinolaringológicas na formação curricular da graduação.

Abstract: Introduction: Otorhinolaryngological disorders are amongst the most prominent frequent diseases in primary care. The overload in secondary care is thought to be a consequence of the low resolution of these problems in primary care. A deficiency in undergraduate medical training may explain this fact. The average estimated time spent studying otorhinolaryngological practice is estimated to be 0.6% of the total average practice hours after analysis of data from 141 medical course syllabuses in Brazil, corresponding to approximately 70.5% of all the medical schools in operation in 2013. Few studies have been conducted in this area and regarding teaching and the need for curriculum reassessment. Objectives: This study seeks to ascertain a consensus on the skills required by the general practitioner in the specialty of otorhinolaryngology. Methods: An initial questionnaire was devised addressing the otorhinolaryngological skills relevant to primary care clinical practice. Using the Delphi method, the questionnaire was sent in electronic format to 20 specialists with training in three different specialties; this heterogeneity of the survey sample helped ensure the reliability of the results. The results obtained after each round were analyzed by one researcher and validated by another, observing any discrepant trends and opinions, as well as their justifications. Once the results had all been compiled and systematized, a new questionnaire was devised and sent out, starting a new round until consensus had been established for all the skills. Results: Five rounds were completed until a consensus was established for all 17 otorhinolaryngological skills evaluated by the propositions. Conclusions: The data obtained by this work can serve as a basis and guideline for developing an otorhinolaryngological curriculum for undergraduate medical training since no consensus was found in the literature establishing such a minimum skill set.
