ABSTRACT
Abstract Objective: To assess the diagnostic agreement between smartphone-enabled otoscopy and rigid otoendoscopy in tympanic membrane and middle ear diseases. Methods: A cross-sectional study was carried out to analyze otoscopies in patients seen at a general otorhinolaryngology (ORL) outpatient clinic, from June to December 2019. Eighty-three images of patients obtained from otoscopies performed through a smartphone device and a rigid endoscope were included, recorded, and stored for further analysis. The images were first analyzed by an experienced otologist, who assigned his diagnostic impression (defined as the gold standard) on each of the images. After this analysis, the images were displayed to a group of secondary raters (an experienced otorhinolaryngologist, a second-year resident in ORL, and a general practitioner). A questionnaire was applied related to each image. Results: There was high agreement between the smartphone device and the otoendoscopy images for all professionals, with a Kappa coefficient of 0.97 (p < 0.001). The smartphone device showed a diagnostic sensitivity of 81.1% and a specificity of 71.1%. As for the otoendoscopy, it showed a sensitivity of 84.7% and a specificity of 72.4%. The image classification as "2 = Good" was the most frequent one, with 34.9% for otoendoscopy and 31.6% for the smartphone device. Conclusion: There was a high diagnostic agreement between smartphone device-guided otoscopy and the rigid otoendoscopy, demonstrating the feasibility of using this device in clinical practice. Level of Evidence: 3
ABSTRACT
ABSTRACT INTRODUCTION: Intrathecal fluorescein has been effective for topographic diagnosis of rhinoliquorrhea. Nonetheless, there are no reports on the study of cerebral spinal fluid (CSF) after use of intrathecal fluorescein. OBJECTIVE: A prospective study attempting to evaluate CSF through chemical and cytological analysis, after injection of fluorescein. METHODS: Prospective analysis of 24 samples of CSF after intrathecal injection of fluorescein for topographic diagnosis of CSF fistulae, collected at the time of puncture and after 24 and 48 h, divided by cellularity: Group 1, up to five cells, and Group 2, with more than five cells. RESULTS: The yellow-greenish color of CSF remained after 48 h in 36%, evidencing permanence of fluorescein. No changes in protein and glucose levels were observed between 0-24 h and 0-48 h. In group 2, an increase in cell count was observed between 24 h and 48 h (p = 0.019). In both groups, there was an increase of neutrophils between 0 and 48 h (p = 0.048) and a decrease between 24 and 48 h (p = 0.05). CONCLUSION: Intrathecal fluorescein provoked discreet meningeal reactions, such as an increase of cells between 24 and 48 h and an increase of neutrophils at 24 h, with a subsequent decrease at 48 h with no correlation with symptomatology.
RESUMO Introdução: A fluoresceína intratecal tem sido efetiva no diagnóstico topográfico da rinoliquorréia. Entretanto, não há estudos no líquor após o uso de fluoresceína intratecal. Objetivo: Estudo prospectivo visando avaliar o líquor, através de análise química e citológica, após injeção de fluoresceína. Método: Análise prospectiva de 24 punções após injeção intratecal de fluoresceína para diagnóstico topográfico de fístula liquórica, coletado no momento da punção, 24 e 48 horas, divididos pela celularidade: grupo 1, com até 5 células e grupo 2 com mais de 5 células. Resultado: A coloração amarelo-esverdeada do líquor permaneceu após 48 horas em 36%, evidenciando permanência de fluoresceína. Observou-se ausência de mudanças no nível de proteína e glicose entre 0-24 horas e 0-48 horas. No grupo 2, um aumento na contagem celular foi observado entre 24 e 48 horas (p = 0,019). No dois grupos juntos, observou-se um aumento de neutrófilos entre 0 e 48 horas (p = 0,048) e uma diminuição entre 24 e 28 horas (p = 0,05). Conclusão: Fluoresceína intratecal provocou discretas reações meníngeas, como o aumento de células entre 24 e 48 horas e aumento dos dos neutrófilos em 24 horas com uma subsequente dimi nuição em 48 horas sem correlação com sintomas.

Opresente documento tem por objetivo esclarecer àqueles que tratam das doenças nasossinusais, tanto especialistas quanto generalistas, sobre as terapêuticas tópicas nasais. Por meio de uma revisão das evidências científicas, a Academia Brasileira de Rinologia vem proporcionar sua visão prática e atualizada sobre as medicações tópicas nasais mais utilizadas, excetuando-se as medicações que possuam antibióticos tópicos na sua formulação.
This documents aims at educating those who treat sinonasal diseases - both general practitioners and specialists - about topical nasal treatments. By means of scientific evidence reviews, the Brazilian Academy of Rhinology provides its practical and updated guidelines on the most utilized topical nasal medication, except for the drugs that have topical antibiotics in their formulas.

O nariz, a garganta e o ouvido intrigam a humanidade desde os períodos mais remotos. Tratamentos laringológicos, rinológicos e otológicos, além de cirurgias, já eram praticados por médicos gregos, hindus e bizantinos. No século XX inovações clínicas e cirúrgicas foram incorporadas graças às novas técnicas anestésicas, aos antibióticos, à radiologia e às novas tecnologias. OBJETIVO E MÉTODO: Mostrar a evolução desta ciência ao longo dos tempos, reconhecendo figuras importantes da otologia, rinologia e laringologia por revisão em literatura. RESULTADO E CONCLUSÃO: O conhecimento das evoluções em anatomia, fisiologia, tratamentos clínicos e cirúrgicos, além das personalidades que conduziram a estes avanços é de grande importância para que a ciência médica evolua cada vez mais. A Otorrinolaringologia tem história muito rica, com importantes colaboradores e figuras de renome para a história da medicina. A especialidade foi uma das primeiras a utilizar anestesia local para realização de procedimentos, pioneira em tratamentos com próteses que recuperavam a audição e teve a primazia na utilização de microscópios em cirurgias. Poucas especialidades médicas sofreram tantas mudanças e desenvolvimentos científicos nestas últimas décadas quanto a Otorrinolaringologia que teve a vantagem de incorporar tecnologias na endoscopia, radiologia, microcirurgia e uso da informática.
Ears, nose and throat have intrigued humanity since immemorial times. Treatments for the larynx, the nose and the ear and also surgeries were practiced by Greek, Hindu and Byzantine doctors. In the 20th century clinical and surgical innovations were incorporated, thanks to new anesthesia techniques, antibiotics, radiology and new technologies. AIM AND METHOD: show the evolution of this science throughout the times, recognizing important persons in otology, rhinology and laryngology. RESULTS AND CONCLUSION: Understanding the evolutions in clinical and surgical anatomy, physiology, treatment modalities, and the personalities that lead to these advances is of great importance for the evolution of medical science. Otorhinolaryngology has a very rich history, with important collaborators and personalities in the history of medicine. The specialty was one of the first to use local anesthesia for procedures, pioneer in treatments with devices that recouped hearing and the use of microscopes in surgeries. Few medical specialties had suffered as many changes and scientific developments in these last decades as Otorhinolaryngology had, with the advantage of incorporating technologies such as endoscopy, radiology, microsurgery and information technology.
