La aspiración de cuerpos extraños es una de las principales causas de ingreso a urgencias y de morbi-mortalidad en Ecuador en pacientes pediátricos. El diagnóstico suele ser tardío, por falta de interés de los cuidadores, o por errores en la valoración. Es importante detectar el cuadro a tiempo, para evitar complicaciones. OBJETIVO. Demostrar la necesidad de un diagnóstico acertado ante la alta sospecha en un cuadro dudoso de aspiración de cuerpo extraño. SERIE DE CASOS. Evaluación de cuatro pacientes de ambos sexos, de entre 11 meses a 15 años de edad con antecedente de ingesta de cuerpo extraño, atendidos en la Unidad Técnica de Cirugía Pediátrica, del Hospital de Especialidades Carlos Andrade Marín, durante el periodo 2019-2020. Se realizó la extracción exitosa mediante broncoscopia rígida en tres de ellos. DISCUSIÓN. La mayoría de pacientes con aspiración de cuerpo extraño suelen ser menores de 5 años de edad, en contraste con éste estudio, donde sólo un paciente estuvo dentro de este rango, y el resto fueron escolares y adolescentes. El cuerpo extraño más común es de origen orgánico; el 50% de los casos observados fue de origen inorgánico. CONCLUSIÓN. El diagnóstico de aspiración de cuerpo extraño se condiciona a la obtención completa de datos sobre la Historia Clínica; requiere una valoración rápida y manejo adecuado por emergencias.


INTRODUCTION. Foreign body aspiration is one of the main causes of emergency room admissions and morbidity and mortality in pediatric patients in Ecuador. Diagnosis is usually late, due to lack of interest of caregivers, or due to errors in the assessment. It is important to detect the condition in time to avoid complications. OBJECTIVE. To demonstrate the need for an accurate diagnosis in the presence of high suspicion in a doubtful picture of foreign body aspiration. CASE SERIES. Evaluation of four patients of both sexes, between 11 months and 15 years of age with a history of foreign body ingestion, attended at the Pediatric Surgery Technical Unit of the Carlos Andrade Marin Specialties Hospital, during 2019-2020 period. Successful extraction by rigid bronchoscopy was performed in three of them. DISCUSSION. Most patients with foreign body aspiration are usually under 5 years of age, in contrast to this study, where only one patient was within this range, and the rest were schoolchildren and adolescents. The most common foreign body is of organic origin; 50% of the cases observed were of inorganic origin. CONCLUSION. The diagnosis of foreign body aspiration is conditioned to the complete collection of data on the Clinical History; it requires a rapid assessment and appropriate emergency management.

A pesquisa teve como objetivo avaliar se radiografias panorâmicas de boca fechada podem ser usadas para observação dos tecidos moles e resistência do fluxo aéreo nas vias aéreas (VA), principalmente da faringe (naso, velo, oro e hipofaringe). Para averiguação do potencial obstrutivo das vias aéreas foram estudados 65 indivíduos adultos (54 do gênero feminino e 11 do gênero masculino), 45 com dores orofaciais e 20 assintomáticos. Estabeleceram-se parâmetros através de uma nova análise radiográfica para avaliação da presença de estruturas de tecido mole potencialmente obstrutoras do fluxo respiratório. Investigou-se a influência que a dor orofacial poderia exercer no fluxo aéreo destas vias respiratórias da cavidade nasal até a entrada dos pulmões. Estes parâmetros foram correlacionados à presença e localização de obstruções de vias aéreas (VA), através da técnica de oscilometria, mensurando diferenças do fluxo aéreo durante o repouso por via nasal e bucal. Secundariamente averiguou-se a possibilidade do uso das radiografias panorâmicas para a determinação da classificação de Angle dos pacientes determinada clinicamente. A classe molar de Angle foi confirmada com facilidade através das radiografias panorâmicas de boca fechada, acrescida da vantagem de visualização bilateral da mandíbula, ao invés da superposição dos lados direito e esquerdo como ocorre nas radiografias cefalométricas, comumente utilizadas para este fim. Concluiu-se que as radiografias panorâmicas de boca fechada são úteis para visualização e investigação preliminar de tecidos moles e do fluxo das vias aéreas superiores, principalmente da nasofaringe, velo e orofaringe, e a cavidade nasal, permitindo a detecção de locais com estreitamento potencialmente obstrutivos ao fluxo aéreo. A análise panorâmica facilitou a avaliação da simetria entre os lados direito e esquerdo das estruturas supracitadas. A presença de dor orofacial não influenciou o fluxo aéreo das VAS(AU)


The objective of this study was to evaluate the use of closed-mouth panoramic radiographs for visualization of soft tissues and airflow resistance of upper airways, especially the pharynx (naso, velo, oro, and hipopharynx regions). This study analyzed 65 adult individuals (54 of the feminine gender and 11 of the masculine gender), 45 with orofacial pain and 20 with no symptoms. Parameters were stablished using a new radiographic analysis for evaluation of the potentially obstructive soft tissues in the airways from the nasal cavity to the lungs. The influence of orofacial pain on the respiratory airflow was investigated. These parameters were correlated to the presence and level of the airway obstruction (VA), using forced oscillation technique or oscillometry were measured by the nose and mouth. The Angle's classes previously determined on the clinical way were verified. The results demonstrated that the closed-mouth panoramic radiographs can be used to soft tissues visualization and initial investigation of airways, mostly at nasopharynx and oropharynx, their potentially obstructive sites, nasal cavity, symmetry between right and left sides of these structures. The analysis of the results also demonstrated, as a specific objective, that the closed-mouth panoramic radiographs could be used easily to the confirmation of the Angle's clinical classification. The closed mouth panoramic radiography showed an advantage of maxillar and mandibular bilateral visualization, instead of the right and left sides overlapping as it occurs in the usually used cephalometric radiography. The closed mouth panoramic radiography showed an advantage of maxillar and mandibular bilateral visualization, instead of the right and left sides overlapping as it occurs in the usually used cephalometric radiography. The orofacial pain did not influence the upper airways

Abstract Introduction: There is no consensus on a single classification system for the obstructive findings in drug-induced sleep endoscopy. Previous classification systems have neglected to address the upper retropalatal obstruction, the segmental division of the lateral pharyngeal wall and the primary or secondary nature of laryngeal collapse. Objective: To propose, illustrate and evaluate a more comprehensive and yet simple classification for drug-induced sleep endoscopy findings. Methods: Cross sectional study in a tertiary sleep surgery unit. A total of 30 patients with obstructive sleep apnea underwent drug-induced sleep endoscopy according to a new classification system called LwPTL, and its findings were analyzed according to obstructive sleep apnea severity and body mass index. LwPTL incorporates the description of upper retropalatal collapse, distinguishes the lateral pharyngeal wall collapse into three levels and clarify when laryngeal collapses are primary or secondary. Results: 93.3% of the patients presented lateral pharyngeal wall collapse, usually at the level of the velum (73.3%). 80% presented multilevel collapse. Regarding the upper retropalatal region, LwPTL identified 10% of the cases presenting lateral salpingopharyngeal obstruction and 6.6% with high palatal collapse. 3.3% presented epiglottic collapse. Patients presenting lower levels of collapse, either from the lateral wall and/or tongue and/or larynx, represented 30% of the cases and had significantly more severe obstructive sleep apnea, without significant differences in body mass indexes. Conclusion: LwPTL seems a simple and straightforward staging system for classifying drug-induced sleep endoscopy, distinguishing the important upper retopalatal obstruction and the primary and secondary laryngeal collapses, providing more information for appropriate treatment selection.


Resumo Introdução: Não há consenso sobre um sistema único de classificação para os achados obstrutivos da endoscopia do sono induzido por drogas. Os sistemas de classificação anteriores negligenciaram a abordagem da obstrução retropalatal alta, a divisão segmentar da parede lateral da faringe e a natureza primária ou secundária do colapso laríngeo. Objetivo: Propor, ilustrar e avaliar uma classificação mais abrangente e simples para os achados da endoscopia do sono induzido por drogas. Método: Estudo transversal em uma unidade terciária de cirurgia do sono. Foram submetidos à endoscopia do sono induzido por drogas 30 pacientes com apneia obstrutiva do sono, de acordo com um novo sistema de classificação denominado LwPTL, e seus achados foram analisados de acordo com a gravidade da apneia obstrutiva do sono e índice de massa corpórea. O LwPTL incorpora a descrição do colapso retropalatal alto, distingue o colapso da parede faríngea lateral em três níveis e esclarece quando os colapsos laríngeos são primários ou secundários. Resultados: Apresentaram colapso da parede faríngea lateral 93,3% dos pacientes, geralmente no nível do palato mole (73,3%). Em 80% dos pacientes o colapso foi multinível. Em relação à região retropalatal alta, o LwPTL identificou 10% dos casos com obstrução salpingo-faríngea lateral e 6,6% com colapso alto do palato. Em 3,3% ocorreu colapso epiglótico. Pacientes com colapso em regiões baixas, tanto da parede lateral e/ou língua como e/ou laringe, representaram 30% dos casos e apresentaram apneia obstrutiva do sono significativamente mais grave, sem diferenças significantes no índice de massa corpórea. Conclusão: O LwPTL parece um sistema de estadiamento simples e direto para classificar os achados da endoscopia do sono induzido por drogas, distingue a importante obstrução retropalatal alta e os colapsos laríngeos primários e secundários, fornece mais informações para uma seleção adequada do tratamento.

Abstract Introduction: Imaging studies have hystorically been used to support the clinical otorhinolaryngological evaluation of the upper respiratory tract for the diagnosis of obstructive causes of oral breathing. Objective: The objective of this study was to compare 3D volumetric measurements of nasal cavity, nasopharynx and oropharynx of obstructed mouth-breathing children with measurements of non-obstructed mouth-breathing children. Methods: This retrospective study included 25 mouth-breathing children aged 5-9 years evaluated by otorhinolaryngological clinical examination, flexible nasoendoscopy and full-head multi-slice computed tomography. Tomographic volumetric measurements and dichotomic otorhinolaryngological diagnosis (obstructed vs. non-obstructed) in three anatomical regions (the nasal cavity, nasopharynx and oropharynx) were compared and correlated. An independent sample t-test was used to assess the association between the 3D measurements of the upper airways and the otorhinolaryngological diagnosis of obstruction in the three anatomical regions. Inter- and intra-observer intraclass correlation coefficients were used to evaluate the reliability of the 3D measurements. Results: The intra-class correlation coefficients ranged from 0.97 to 0.99. An association was found between turbinate hypertrophy and nasal cavity volume reduction (p < 0.05) and between adenoid hyperplasia and nasopharynx volume reduction (p < 0.001). No association was found between palatine tonsil hyperplasia and oropharynx volume reduction. Conclusions: (1) The nasal cavity volume was reduced when hypertrophic turbinates were diagnosed; (2) the nasopharynx was reduced when adenoid hyperplasia was diagnosed; and (3) the oropharynx volume of mouth-breathing children with tonsil hyperplasia was similar to that of non-obstructed mouth-breathing children. The adoption of the actual anatomy of the various compartments of the upper airway is an improvement to the evaluation method.


Resumo Introdução: O exame clínico otorrinolaringológico da via aérea superior tem sido historicamente feito com a ajuda de imagens radiográficas para diagnosticar causas obstrutivas da respiração bucal. Objetivo: O objetivo deste estudo foi comparar as medidas volumétricas em 3D da cavidade nasal, nasofaringe e orofaringe entre crianças com respiração bucal e obstrução respiratória e crianças respiradoras bucais sem obstrução respiratória. Método: Estudo retrospectivo que inclui 25 crianças respiradoras bucais de 5 a 9 anos. As crianças foram avaliadas por exame clínico otorrinolaringológico, nasofibroscopia flexível e tomografia computadorizada multi-slice. Medidas volumétricas obtidas tomograficamente de três regiões anatômicas (cavidade nasal, nasofaringe e orofaringe) foram correlacionadas e comparadas com diagnóstico dicotômico otorrinolaringológico (obstruído vs. não obstruído). Um teste t de amostra independente foi usado para avaliar a associação entre as medidas em 3D das vias aéreas superiores e o diagnóstico otorrinolaringológico de obstrução nas três regiões anatômicas. Os coeficientes de correlação intraclasse inter e intraobservador foram usados para avaliar a confiabilidade das medidas em 3D. Resultados: O coeficiente de correlação intraclasse variou de 0,97 a 0,99. Uma associação foi encontrada entre a hipertrofia de conchas e a redução do volume da cavidade nasal (p < 0,05) e entre a hiperplasia de tonsila faríngea e a redução do volume da nasofaringe (p < 0,001). Não foi encontrada associação entre a hiperplasia da tonsila palatina e a redução do volume da orofaringe. Conclusões: 1) O volume da cavidade nasal estava reduzido nas crianças com diagnóstico de hipertrofia de conchas; 2) O volume da nasofaringe estava reduzido nas crianças com diagnóstico de hiperplasia de tonsila faríngea; e 3) O volume da orofaringe de crianças com respiração bucal e hiperplasia de tonsila palatina foi semelhante ao de crianças respiradoras bucais sem aumento da tonsila palatina. A adoção da mensuração anatômica dos vários compartimentos da via aérea superior complementa o método de avaliação.

El síndrome de obstrucción congénita de la vía aérea superior (CHAOS), es una condición infrecuente que causa asfixia o muerte perinatal inmediata, de no mediar una estrategia terapéutica que permita permeabilizar la vía aérea del paciente durante el nacimiento. El diagnóstico prenatal, es fundamental para delinear estrategias de tratamiento perinatal con el fin de minimizar la morbimortalidad de niños con anomalías congénitas. El tratamiento ex-útero intraparto (EXIT) es el procedimiento de elección. Clásicamente se realiza mediante una cesárea programada, manteniendo el soporte fetal a través de la circulación útero-placentaria. Se requiere un equipo altamente calificado y un trabajo coordinado para concretar el procedimiento en estas condiciones. Objetivo: El objetivo es reportar un caso de Síndrome de CHAOS, en el que se realizó un procedimiento EXIT en un niño nacido por parto vaginal, con la participación de un equipo multidisciplinario de profesionales de dos Instituciones Públicas de la Ciudad de Buenos Aires, en el marco de un Programa Conjunto de Diagnóstico y Tratamiento Fetal (AU)


Congenital high airway obstruction syndrome (CHAOS) is a rare entity causing perinatal asphyxia or immediate death if no therapeutic strategy is undertaken to correct airway patency at birth. Prenatal diagnosis is essential to plan perinatal strategies to decrease morbidity and mortality in children with congenital anomalies. The exutero intrapartum treatment (EXIT) is the procedure of choice. Classically, a programmed cesarean section is performed while the fetus is maintained on uteroplacental circulation. A highly trained team is required in the coordinated effort to perform the procedure. Aim: The aim of this study was to report on a case of CHAOS managed with an EXIT procedure in a child born through vaginal delivery performed by a multidisciplinary team of professionals belonging to two public institutions of the city of Buenos Aires in the framework of the Joint Program of Fetal Diagnosis and Treatment (AU)

OBJECTIVE: The aim of this study was to evaluate whether the difference in the degree of collateral ventilation between canine and swine models of bronchial obstruction could be detected by using xenon-enhanced dynamic dual-energy CT. MATERIALS AND METHODS: Eight mongrel dogs and six pigs underwent dynamic dual-energy scanning of 64-slice dual-source CT at 12-second interval for 2-minute wash-in period (60% xenon) and at 24-second interval for 3-minute wash-out period with segmental bronchus occluded. Ventilation parameters of magnitude (A value), maximal slope, velocity (K value), and time-to-peak (TTP) enhancement were calculated from dynamic xenon maps using exponential function of Kety model. RESULTS: A larger difference in A value between parenchyma was observed in pigs than in dogs (absolute difference, -33.0 +/- 5.0 Hounsfield units [HU] vs. -2.8 +/- 7.1 HU, p = 0.001; normalized percentage difference, -79.8 +/- 1.8% vs. -5.4 +/- 16.4%, p = 0.0007). Mean maximal slopes in both periods in the occluded parenchyma only decreased in pigs (all p < 0.05). K values of both periods were not different (p = 0.892) in dogs. However, a significant (p = 0.027) difference was found in pigs in the wash-in period. TTP was delayed in the occluded parenchyma in pigs (p = 0.013) but not in dogs (p = 0.892). CONCLUSION: Xenon-ventilation CT allows the quantification of collateral ventilation and detection of differences between canine and swine models of bronchial obstruction.
