Resumen EPOS 2020 (European Position Paper on Rhinosinusitis and Nasal Polyps 2020) es una guía clínica desarrollada por un grupo profesionales expertos en el área rinosinusal de la Sociedad Europea de Rinología, que corresponde a la última actualización de sus versiones anteriores (2005, 2007 y 2012). El objetivo principal del documento es entregar recomendaciones claras basadas en la mejor evidencia disponible y algoritmos de manejo concisos para las patologías de rinosinusitis aguda y crónica tanto en adultos como en pacientes pediátricos. Algunas de las novedades más importantes de esta guía, son: nueva clasificación de rinosinusitis crónica en primarias y secundarias, rinosinusitis crónica en pediatría, nuevos conceptos en cirugía sinusal, entre otros. También enfatiza la importancia de manejo multidisciplinario de la patología, incluyendo el autocuidado del paciente, inclusive promoviendo el uso de medicamentos de venta libre, antes del manejo médico en niveles escalonados de atención. El objetivo de esta revisión es dar a conocer de manera resumida el manejo de rinosinusitis aguda y crónica en adultos propuesta en esta guía.

Abstract EPOS 2020 (European Position Paper on Rhinosinusitis and Nasal Polyps 2020) is a clinical guide developed by a group of professional experts in the rhinosinusal area of the European Society of Rhinology, which corresponds to the latest update of its previous versions (2005, 2007 and 2012). The main objective of the document is to bring clear recommendations based on the best available evidence and concise management algorithms for the pathologies of acute and chronic rhinosinusitis in both adults and pediatric patients. Some of the most important novelties of this guide are: new classification of chronic rhinosinusitis in primary and secondary, chronic rhinosinusitis in pediatrics, new concepts in sinus surgery, among others. It also emphasizes the importance of multidisciplinary management of the pathology, including self-care of the patient, promoting the use of over-the-counter medications, before medical management at tiered levels of care. The objective of this review is to present in a summarized way the management of acute and chronic rhinosinusitis in adults proposed in this guide.

Predictive diagnostic value of serum 25-hydroxyvitamin D3 in eosinophilic chronic rhinosinusitis with nasal polyps / 中华耳鼻咽喉头颈外科杂志

Objective: To compare the value of 25-hydroxyvitamin D3 (25-(OH)D3) with other clinical parameters in the prediction and diagnosis of eosinophilic chronic rhinosinusitis with nasal polyps (ECRSwNP). Methods: Eligible chronic rhinosinusitis with nasal polyps (CRSwNP) patients and healthy subjects in the Affiliated Hospital of Guizhou Medical University from January to April of 2021 were included for this study. The age, gender, past history and other basic characteristics of all subjects were recorded. The CRSwNP patients were classified into ECRSwNP and non-eosinophilic chronic rhinosinusitis with nasal polyps (nECRSwNP) endotypes by the percentage of tissue eosinophils. Serum 25-(OH)D3 levels measurements were performed in all subjects. Paranasal sinus CT scans, blood eosinophil counts, and determination of total immunoglobulin E (total IgE), Th1/Th2 plasma cytokines and nasal nitric oxide (nNO) levels were performed before surgery. Logistic regression analysis was used to evaluate the related factors of ECRSwNP. Receiver operating characteristic (ROC) curves was used to evaluate the predictive potential of the clinical parameters. Results: One hundred and twenty-seven CRSwNP patients and 40 healthy subjects were recruited, including 74 males and 93 females of the patients, with the age of (38.73±13.05) years. In patients with ECRSwNP, serum 25-(OH)D3 levels were significantly lower than those in nECRSwNP patients ((26.14±4.58) ng/ml vs (35.71±7.86) ng/ml, t=-8.564, P<0.01). The prevalence of asthma, prevalence of allergic rhinitis, peripheral blood eosinophil counts, total IgE levels, nNO levels and CT scores ratio for ethmoid sinus and maxillary sinus (E/M ratio) of ECRSwNP patients were significantly higher than those in nECRSwNP patients (all P<0.05). However, there was no significant difference in Th1/Th2 cytokines levels between the histological types of CRSwNP (all P>0.05). Among the predictive indicators, 25-(OH)D3 had the highest predictive value, with ROC area under curve (AUC) value of 0.882. The best cut-off point of 28.5 ng/ml for 25-(OH)D3 demonstrated a sensitivity of 0.871 and a specificity of 0.762 for ECRSwNP. Conclusion: Measurement of serum 25-(OH)D3 level may be used as an effective method to distinguish between ECRSwNP and nECRSwNP.

Rinosinusitis crónica en niños: revisión de la evaluación y manejo actual / Chronic rhinosinusitis in children: review of the evaluation and current management

La rinosinusitis crónica (RSC) en niños corresponde a la inflamación de la mucosa de la cavidad nasal y senos paranasales, presentando síntomas como obstrucción nasal, descarga nasal, presión o dolor facial y tos, presentes por más de 12 semanas. Conlleva una gran carga de morbilidad para quienes la padecen, y un alto costo económico. Su diagnóstico constituye un desafío debido a la sobreposición de síntomas con infecciones respiratorias altas y otras condiciones no infecciosas. En los últimos años se han dilucidado nuevos factores contribuyentes como los biofilms , disfunción del microbioma, y el creciente papel de mecanismos inflamatorios no infecciosos. El estudio imagenológico de elección es la tomografía computarizada, preferentemente en casos de duda diagnóstica, falta de respuesta a tratamiento o sospecha de complicaciones. El tratamiento de primera línea es el manejo médico, basado en irrigación nasal, posible uso de antibióticos prolongados y corticoides nasales. Para casos refractarios se plantean intervenciones quirúrgicas, siendo la adenoidectomía la primera elección, principalmente en niños menores; otras intervenciones incluyen la cirugía endoscópica de cavidades paranasales. Nuevas terapias biológicas están siendo estudiadas basadas en los mecanismos inflamatorios no infecciosos de la RSC y su relación con comorbilidades como el asma.

Chronic rhinosinusitis (CRS) in children is the inflammation of the nasal and sinus mucosa, presenting symptoms such as obstruction, nasal discharge, pressure or facial pain and cough, which extends for more than 12 weeks. It represents a great burden for those affected, with high economic cost. Its diagnosis constitutes a challenge due to the overlap of symptoms with other upper respiratory infections and other non-infectious conditions. In recent years, new contributing factors have been elucidated, such as biofilms, microbiome dysfunction, and the growing role of noninfectious inflammatory mechanisms. Diagnosis depends on the recognition of characteristic symptoms and their duration. The imaging study of choice is computed tomography, especially in cases of diagnostic doubt, lack of response to treatment or suspicion of complications. First-line treatment of is based on nasal irrigation, possible use of prolonged antibiotics and nasal corticosteroids. For refractory cases, surgical intervention is proposed, with adenoidectomy being the first choice, mainly in younger children; other interventions include endoscopic sinus surgery. New biological therapies are being studied based on noninfectious inflammatory mechanisms of CRS and its comorbidities such as asthma.

Rinosinusitis fúngica invasiva aguda: actualización en pacientes adultos y pediátricos / Acute invasive fungal rhinosinusitis: update in adults and pediatric patients

RESUMEN La rinosinusitis fúngica invasiva aguda (RSFIA) es una enfermedad poco frecuente caracterizada por una infiltración fúngica de la submucosa y vasos sanguíneos de las cavidades nasal y paranasal. Afecta a pacientes con grados variables de inmunosupresión, destacando entre estas patologías subyacentes la diabetes mellitus y las neoplasias malignas hematológicas. Presenta una alta tasa de mortalidad, pudiendo reducirse significativamente si el diagnóstico y el tratamiento se realizan precozmente. Este artículo tiene por objetivo presentar una revisión actualizada de la literatura respecto a la presentación clínica, microbiología, factores de riesgos, métodos diagnósticos, tratamiento y pronóstico de la RSFIA, tanto en adultos como en niños.

ABSTRACT Acute invasive fungal rhinosinusitis (AIFS) is a rare disease characterized by fungal infiltration of the submucosa and blood vessels of the nasal y paranasal cavities. It affects almost exclusively patients with different degrees of immunosuppression, with underlying pathologies such as diabetes mellitus and hematological malignancies. AIFS has a high mortality rate, but it can be significantly reduced if the diagnosis and treatment are carried out early in the course of disease. This article aims to present an updated literature review regarding clinical presentation, microbiology, risk factors, diagnostic methods, treatment and prognosis of AIFS, both in adults and children.

Sinusitis en Pediatría / Sinutisis in Pediatrics

Resumen Sinusitis, definida como enfermedad inflamatoria de la mucosa de los senos paranasales, es una enfermedad con alta prevalencia e incidencia en la población general, especialmente en Pediatría.1 Los padecimientos alérgicos e infecciosos de la mucosa nasal representan dos de las enfermedades más frecuentes de las vías aéreas superioras crónicas en niños y adultos jóvenes. Es un problema de salud pública de gran magnitud debido a su alta prevalencia, lo que ocasiona gran presión asistencial en términos de consultas ambulatorias, deterioro significativo de la calidad de vida para el paciente y sus familiares además, implica un fuerte impacto en la comunidad por los altos costos socioeconómicos que generan.2 Su etiología multifactorial y la creciente resistencia bacteriana a antibióticos, especialmente a penicilinas naturales o sintéticas sugiere reconsiderar los fundamentos anatómicos y funcionales con la finalidad de establecer conductas razonables de diagnóstico, terapéutica médica y quirúrgica que permitan un diagnóstico y tratamiento apropiado para disminuir su recurrencia.1,2

Abstract Sinusitis, defined as an inflammatory disease of the paranasal sinuses, is a disease with high prevalence and incidence in the general population, especially among children. The allergic and infectious diseases of the nasal mucosa represent two of the most frequent diseases of the chronic upper airways in children and young adults. It is a public health problem of great magnitude due to its high prevalence, which causes great assistance pressure in terms of outpatient consultations, significant deterioration of the quality of life for the patient and their families, and it also implies a strong impact on the community due to the high socio-economic costs. Its multifactorial etiology and the increasing bacterial resistance to antibiotics, especially natural or synthetic penicillins, suggest reconsidering the anatomical and functional foundations in order to establish reasonable diagnostic, medical and surgical therapeutic behaviors that allow a diagnosis and appropriate treatment to decrease its recurrence.

Sinusitis aguda invasiva por Exserohilum rostratum en una paciente pediátrica con recaída medular de leucemia linfoblástica aguda / Invasive acute sinusitis by Exserohilum rostratum in a patient with medullary relapse of acute lymphoblastic leukemia

La infección fúngica invasora ha aumentado en frecuencia a lo largo de la última década, y la sinusitis fúngica es cada vez más habitual. Los hongos del género Exserohilum (familia Pleosporaceae, orden Pleosporales) son filamentosos y dematiáceos, de localización ubicua. Se trata de patógenos emergentes, que producen, en la mayoría de los casos, infecciones sistémicas que afectan, principalmente, a los senos paranasales y los pulmones. Son más frecuentes en pacientes inmunosuprimidos, aunque pueden presentarse en pacientes inmunocompetentes. El tratamiento de estas infecciones comprende el tratamiento antifúngico, resección quirúrgica y restitución de la inmunidad. Se presenta el caso de una paciente con recaída medular de leucemia linfoblástica aguda con sinusitis fúngica invasiva por Exserohilum rostratum.

Invasive fungal infection has increased in frequency over the last decade, with fungal sinusitis becoming more frequent. The fungi of the genus Exserohilum (family Pleosporaceae, order Pleosporales) are filamentous and dematiaceous of ubiquitous location. It is an emerging pathogen, which in most cases produces a systemic infection that mainly affects the paranasal sinuses and lungs. It is more common in immunosuppressed patients, although it may occur in immunocompetent patients. The treatment is based on three pillars: antifungal treatment, surgical debridement and restitution of immunity. We present the case of a patient with medullary relapse of acute lymphoblastic leukemia with invasive fungal sinusitis by Exserohilum rostratum.

Chronic rhinosinusitis and nasal polyposis in cystic fibrosis: update on diagnosis and treatment / Rinossinusite crônica e polipose nasossinusal na fibrose cística: atualização sobre diagnóstico e tratamento

Although cystic fibrosis (CF) is an irreversible genetic disease, advances in treatment have increased the life expectancy of CF patients. Upper airway involvement, which is mainly due to pathological changes in the paranasal sinuses, is prevalent in CF patients, although many are only mildly symptomatic (with few symptoms). The objective of this literature review was to discuss the pathophysiology and current therapeutic management of chronic rhinosinusitis (CRS) in CF patients. The review was based on current evidence, which was classified in accordance with the Oxford Centre for Evidence-Based Medicine criteria. When symptomatic, CRS with nasal polyps can affect quality of life and can lead to pulmonary exacerbations, given that the paranasal sinuses can be colonized with pathogenic bacteria, especially Pseudomonas aeruginosa. Infection with P. aeruginosa plays a crucial role in morbidity and mortality after lung transplantation in CF patients. Although clinical treatment of the upper airways is recommended as initial management, this recommendation is often extrapolated from studies of CRS in the general population. When sinonasal disease is refractory to noninvasive therapy, surgery is indicated. Further studies are needed in order to gain a better understanding of upper airway involvement and improve the management of CRS in CF patients, with the objective of preserving lung function and avoiding unnecessary invasive procedures.

A fibrose cística (FC) é uma doença genética irreversível, mas os avanços no tratamento têm aumentado a expectativa de vida dos pacientes. O acometimento das vias aéreas superiores, principalmente por alterações patológicas dos seios paranasais, é prevalente nesses pacientes, embora muitos apresentem poucos sintomas. O objetivo desta revisão é discutir a fisiopatologia e o manejo terapêutico atual da rinossinusite crônica (RSC) na FC. A revisão fundamentou-se nas evidências mais recentes, classificadas em conformidade com os critérios do Oxford Centre for Evidence-Based Medicine. Quando sintomática, a RSC com pólipos nasais pode afetar a qualidade de vida e as exacerbações pulmonares, já que os seios paranasais podem ser colonizados por bactérias patogênicas, principalmente a Pseudomonas aeruginosa. Essa bactéria tem papel crucial na morbidade e mortalidade após o transplante pulmonar em pacientes com FC. Embora o tratamento clínico das vias aéreas superiores seja indicado no manejo inicial, a indicação é muitas vezes extrapolada de estudos sobre RSC na população geral. A cirurgia é a alternativa quando o quadro nasossinusal é refratário à terapia não invasiva. Mais estudos são necessários para compreender melhor o acometimento das vias aéreas superiores e melhorar o manejo da RSC na FC, a fim de preservar a função pulmonar e evitar procedimentos invasivos desnecessários.

Trends in the clinical Pattern, diagnosis and management of rhinosinusitis in a sub-urban tertiary health centre

Background: Rhinosinusitis (RSS) is a common form of upper airway disease encountered by Otolaryngologists. Objectives: To describe the trends in the clinical presentation, diagnosis and management of RSS in a tertiary hospital.Methods:Retrospective analysis of clinical information retrieved from the hospital records of patients with RSS managed in the ENT department of OOUTH Sagamu over an 18-month period was done.Results: Out of 1814 patients, 143 had RRS with the prevalence rate of 7.9%. The male-to-female ratio was 1.1:1, the age ranged from 7 to 79 (median = 32.4) years. The presenting symptoms included mucoid nasal discharge (68.7%), nasal congestion (61.5%) and excessive sneezing (46.8%). Most (71.3%) of the patients presented after 3weeks of the onset of symptoms and the median duration was 3.2 months. The leading physical findings included engorged nasal turbinates (78.3%), ooedematous nasal mucosa (72.0%), mucopurulent anterior rhinorrhoea (28.6%) and pale nasal mucosa (25.9%). The investigations done included plain X-Rays of the sinuses (86.0%), full blood count (67.1%) and computerized tomographic (CT) scan of the sinuses (8.4%). Plain X-Ray abnormalities were most common in the maxillary sinuses (45.5%) while 30.1% had multi-sinusitis. The trend of diagnosis ranged from infective RSS in 51.7% to allergic RSS in 38.5%. About a quarter had different forms of non-endoscopic surgical intervention. Recorded complications included nasal polyps in 11.9%. Conclusion: The trend of RSS observed relative affectation of adults and mostly chronic infective types, and sometimes allergic types.Radiological assessment was by plain X-Rays in most cases, management was either medical or non-endoscopic surgical methods, frequently complicated by polyps

Sinonasal disorders in hematopoietic stem cell transplantation / Afecções nasossinusais em pacientes transplantados de células-tronco hematopoiéticas,

INTRODUCTION: hematopoietic stem cell transplantation (HSCT) is associated with more respiratory infections due to immunosuppression. OBJECTIVE: this study aimed to verify the frequency of rhinosinusitis after HSCT, and the association between rhinosinusitis and chronic graft vs. host disease (GVHD) and type of transplantation, clinical treatment, surgical treatment, and survival. METHODS: this was a retrospective study in a tertiary university hospital. A total of 95 patients with hematological diseases undergoing HSCT between 1996 and 2011 were selected. RESULTS: chronic myeloid leukemia was the most prevalent disease. The type of transplant most often performed was the allogenic type (85.26%). The frequency of rhinosinusitis was 36%, with no difference between the autologous and the allogenic types. Chronic GVHD occurred in 30% of patients. Patients with GVHD had a higher frequency and recurrence of rhinosinusitis, in addition to more frequent need for endoscopic sinusectomy and decreased overall survival. CONCLUSION: there was a higher frequency of rhinosinusitis in HSCT and GVHD. The type of transplant does not appear to predispose to the occurrence of rhinosinusitis. GVHD seems to be an aggravating factor and requires a more stringent treatment. .

INTRODUÇÃO: O transplante de células troncas hematopoiéticas (TCTH) associa-se a mais infecções respiratórias devido a imunossupressão. OBJETIVO: Este trabalho tem o objetivo de verificar a frequência das rinossinusites pós-TCTH, a associação entre a rinossinusite e a doença do enxerto contra hospedeiro (DECH) crônico e o tipo de transplante e o tratamento clinico e o tratamento cirúrgico e a sobrevida. MÉTODO: Estudo retrospectivo em hospital universitário terciário. Foram selecionados 95 pacientes com doença hematológica submetidos a TCTH entre 1996 a 2011. RESULTADOS: A leucemia mieloide crônica foi a doença mais prevalente. O tipo de transplante mais realizado foi o alogênico (85,26%). A frequência de rinossinusite foi de 36%, sem diferença entre os tipos de transplante autólogo e alogênico. A DECH crônica ocorreu em 30% dos pacientes. Os pacientes com DECH tiveram maior frequência e recorrência de rinossinusite, além de mais necessidade de sinusectomia endoscópica e de diminuição da sobrevida global. CONCLUSÃO: Houve maior frequência de rinossinusite no TCTH e DECH. O tipo de transplante não parece predispor a ocorrência da rinossinusite. A DECH parece ser um fator agravante e necessita de tratamento mais rigoroso. .

Gripe ou resfriado? Sinusite ou rinite? / Influenza or cold? Sinusitis or rhinitis?

Resfriado comum e gripe são habitualmente confundidos, principalmente se o resfriado for mais intenso. Coriza é rotulada tanto como alergia como sinusite. Os processos inflamatórios das vias aéreas superiores envolvidos nessas entidades clínicas conjugam fatores comuns, embora tenham etiologias diferentes. Graças a isso, diagnósticos equivocados geram tratamento inadequado, geralmente com emprego desnecessário de antibióticos. O resfriado comum e a gripe (influenza) são infecções virais do trato respiratório, assim como a maioria das rinossinusites. Já a rinite é, em sua maior parte, manifestação da atopia respiratória.

Common cold and flu are usually confused, especially if the cold is more intense. Many times, coryza is labeled as being allergy or sinusitis. The inflammation of the upper airways involved in these clinical entities combine common factors, although they have different etiologies. As a result, misdiagnosis generates inadequate treatment, usually with unnecessary use of antibiotics. The common cold and the flu (influenza) are viral infections of the respiratory tract, as well as most cases of rhinosinusitis. On the other hand, rhinitis is, most of the time, a manifestation of respiratory atopy.

A case of Kartagener’s syndrome: Importance of early diagnosis and treatment.

Kartagener’s syndrome is a very rare congenital malformation comprising of a classic triad of sinusitis, situs inversus and bronchiectasis. Primary ciliary dyskinesia is a genetic disorder with manifestations present from early life and this distinguishes it from acquired mucociliary disorders. Approximately one half of patients with primary ciliary dyskinesia have situs inversus and, thus are having Kartagener syndrome. We present a case of 12 year old boy with sinusitis, situs inversus and bronchiectasis. The correct diagnosis of this rare congenital autosomal recessive disorder in early life is important in the overall prognosis of the syndrome, as many of the complications can be prevented if timely management is instituted, as was done in this in this case.

Correlation of preoperative sinusitis patients' characteristics with final diagnostic findings

Chronic rhinosinusitis [CRS] is a common disease which is usually diagnosed clinically, considering the combination of natural history, physical examination and imaging studies. This study aimed to evaluate the clinical value of routine postoperative histopathologic examination [POHE] in patients with a clinical diagnosis of chronic rhinosinusitis with polyposis [CRSWP], or without polyposis [CRSWOP One hundred of patients with clinically approved CRSWP and CRSWOP were enrolled in this study. All patients underwent complete physical examination, scoring paranasal sinuses involvement by Lund-Mackay [LM] CT scoring scale, determining the extent of polyposis by Stumberger's endoscopic classification, and assessing health related quality of life by Sinonasal Test 22 [SNOT22] questionnaire. After FESS, histopathologic results were compared with preoperative clinical diagnosis. Among our patients, 65% were male, and the rest of them were female. Also, 66% of them suffered from CRSWP, and the rest of them were CRSWOP. LM CT score and SNOT22 score was 36.62 +/- 12, 17.11 +/- 6, and 43.62 +/- 20 respectively. Only in one of patients with CRSWP, POHE was other than what was expected preoperatively [adenoid cystic carcinoma]. In all other cases, POHE was well correlated with preoperative clinical diagnosis. HRQOL was better in males, absence of septal deviation and CRSWOP [P<0.05]. Para nasal sinuses involvement in preoperative CT was more severe in the presence of eosinophil in POHE [P=0.008] and in patients with class 3 Stumberger's classification [P<0.001]. This study suggested preoperative clinical diagnosis of CRS considering the combination of natural history, physical examination and imaging studies can be accurate, and POHE is indicated only in suspicious cases.

Allergic fungal sinusitis in a 5 years old child

The aim of this case is to focus on the importance of early diagnosis of allergic fungal sinusitis in children since it is well know that this disease can affect all age groups and can lead to dysmorphic facial features in children in case of delayed diagnosis

Avaliação da integridade da cortical do seio maxilar em proximidade a lesões periapicais simuladas em maxilas suínas maceradas por meio da Tomogr Computadorizada por Feixe Cônico / Integrity evaluation of the cortical sinus in proximity to periapical lesions simulated in macerated swine maxillae by cone beam computed tomography

A detecção de periapicopatias comprometendo a cortical sinusal pode ser subestimada em radiografias periapicais, que é o exame de rotina, pela sobreposição de estruturas. Neste estudo, a sensibilidade, especificidade e reprodutibilidade da TCFC para a avaliação da integridade da cortical sinusal próxima de lesões periapicais (com e sem comunicação oroantral) foram avaliadas em relação a um padrão-ouro (erosões na região periapical de molares superiores em 20 maxilas suínas maceradas). Foi realizada a primeira etapa de aquisições com as maxilas íntegras, visando familiarizar os observadores com a anatomia da maxila suína e excluir da amostra os sítios com defeitos ósseos pré-existentes. Após isso, foram extraídos os primeiros-molares e lesões periapicais foram simuladas com ácido perclórico. A duração da exposição ao ácido foi controlada em dois tempos: T1 que gerou lesões incipientes e T2 que gerou lesões maiores. O estabelecimento de comunicação oroantral deu-se em 22 sítios. Em seguida, os dentes foram reimplantados nos devidos alvéolos. Realizou-se a segunda etapa de aquisições. Dois observadores, devidamente familiarizados com lesões simuladas na maxila suína com e sem comunicação, avaliaram os exames duas vezes, com intervalo de tempo de uma semana. Todos os exames estavam em ordem aleatória em uma estação de trabalho independente contendo o software OsiriX MD. Os resultados demonstraram uma boa acurácia (66 a 78%) e alta especificidade (70 a 98%) com índices moderados de concordância intraobservadores (0,49 e 0,56), porém gerou resultados distintos de sensibilidade (41%, 55%, 78% e 60%) que culminou em um baixo índice de concordância interexaminadores (0,21 e 0,35). A maior dificuldade relatada pelos observadores foi a alta presença de ruído na imagem, influenciada principalmente pela relação do FOV e voxel que acabou afetando a resolução da imagem do exame.

The detection of periapical diseases affecting the cortical sinus may be underestimated in periapical radiographs, which is the method of choice, by overlapping structures. In this study, the sensitivity, specificity and reproducibility of CBCT to assessing the integrity of the cortical sinus near periapical lesions (with and without communication oroantral) were evaluated by comparing with a gold standard (erosions in the periapical region of maxillary molars in 20 maxillae swine macerated). We performed the first step of acquisitions with intact maxillae in order to acquaint the observers with the swine anatomy and delete the sample sites with pre - existing bone defects. After this, we extracted the first premolar and simulated periapical lesions with perchloric acid . The duration of acid exposure was controlled in two stages: generating incipient lesions T1 and T2 which generated larger lesions. Establishing oroantral communication was more related to the proximity with the alveolus then the periapical periodontitis size, generating 22 sites with communication. Then the teeth were reimplanted in the appropriate dental alveoli to the next tomographic acquisitions. Two trained observers evaluated the tests twice, with an interval of a week's time. All tests were in random order on a standalone workstation with software OsiriX MD. The results demonstrated good accuracy (66 to 78%) and high specificity (70% to 98%) and moderate rate of intraobserver concordance (0,49 and 0,56)trai, but generated different results of sensitivity (41%, 55%, 78% and 60%) which culminated in a low rate of interobserver concordance (0,35 and 0,21). The main difficulty reported by the observers was the high presence of image noise, mainly influenced by the ratio of the FOV and voxel that ended up affecting the reliability of the examination.

Manejo das infecções agudas das vias aéreas superiores para o pediatra geral / Management of acute upper airway infections for the general pediatric

O artigo tem por objetivo revisar o manejo inicial das infecções agudas de vias aéreas superiores prevalentes em crianças, com foco nas rinossinusites e nas faringoamigdalites. Discute-se o diagnóstico diferencial entre infecções virais e bacterianas e a indicação do uso de antimicrobianos.

The purpose of this article is to rewiew the initial management of the most prevalent upper respiratory tract infections in children focusing on rhinosinustis and pharyngotonsilitis. Also provides discussion on the differencial diagnosis between viral e bacterial infecctions and the recommendations to the use of antimicrobial therapy.
