ABSTRACT
Introducción: La enfermedad pulmonar obstructiva crónica cursa con un patrón inflamatorio en la vía aérea que incluye neutrófilos, macrófagos, linfocitos, los cuales se pueden obtener mediante un cepillado bronquial citológico. Objetivos: Identificar patrón inflamatorio según células inflamatorias presentes en la vía aérea, mediante el cepillado bronquial citológico e índice tabáquico de paquetes/año en pacientes con enfermedad pulmonar obstructiva crónica. Métodos: Se realizó un estudio descriptivo transversal en pacientes con enfermedad pulmonar obstructiva crónica, que concurrieron al Hospital Neumológico Benéfico-Jurídico, en el período comprendido de junio de 2018 a junio de 2019, con indicación para la realización de fibrobroncoscopía con cepillado bronquial. Resultados: El 53,1 por ciento de los pacientes corresponden al sexo masculino. Un 46,1 por ciento presentó un índice tabáquico de paquetes/año entre 21-40. Predominaron las criptas y estrías como hallazgos broncoscópicos con un 51 por ciento y 40,8 por ciento respectivamente en pacientes con índice paquetes/año mayor que 40. De los pacientes con índice paquetes/año mayor de 40 (13 para un 26,5 por ciento) presentaron hiperplasia de células basales. El 46,9 por ciento de los pacientes presentaron un patrón inflamatorio neutrofílica. Conclusiones: Se identificaron a los pacientes con EPOC que presentaron patrón inflamatorio neutrofílica en la vía aérea y elevado índice tabáquico y desde el punto de vista broncoscópico tienen varios hallazgos que sugieren cronicidad(AU)
Introduction: Chronic obstructive pulmonary disease presents with an inflammatory pattern in the airway that includes neutrophils, macrophages, and lymphocytes, which can be obtained by cytological bronchial brushing. Objectives: To identify inflammatory pattern according to inflammatory cells present in the airway, through cytological bronchial brushing and smoking rate of packs/year in patients with chronic obstructive pulmonary disease. Methods: A cross-sectional descriptive study was carried out in patients with chronic obstructive pulmonary disease, who attended Benefico-Jurídico Pneumological Hospital, from June 2018 to June 2019, with an indication for fiberoptic bronchoscopy with bronchial brushing. Results: 53.1percent of the patients correspond to the male sex. 46.1percent ad a smoking rate of packs/year between 21-40. Crypts and striae predominated as bronchoscopic findings with 51percent and 40.8percent respectively in patients with a pack/year index greater than 40. Patients with a pack/year index greater than 40 (13 for 26.5percent) showed basal cell hyperplasia. 46.9percent of the patients had a neutrophilic inflammatory pattern. Conclusions: Patients with COPD who had a neutrophilic inflammatory pattern in the airway and high smoking index were identified, and from the bronchoscopic point of view they have several findings that suggest chronicity(AU)

Background: Tracheobronchial stenosis, particularly central airway stenosis, which frequently results in severe complications such as lung damage, occurs in patients with tracheobronchial tuberculosis (TBTB). Objectives: To analyze the clinical characteristics of patients with central airway stenosis due to tuberculosis (CASTB). Methods: Retrospective analysis was performed on the clinical features, radiological features, bronchoscopic features and treatment of 157 patients who were diagnosed with CASTB in two tertiary hospitals in Chongqing, China, from May 2020 to May 2022. Results: CASTB mostly occurs in young patients and females. Patients with CASTB exhibited different symptoms repeatedly during the disease, especially varying degrees of dyspnea, prompting many patients to undergo bronchoscopic intervention and even surgery. Patients with cicatricial strictures constituted the highest proportion of the TBTB subtype with CASTB and 35.7% of the patients with CASTB were found to have tracheobronchomalacia (TBM) under bronchoscopy. CASTB and TBM mainly involved the left main bronchus. Patients with lower levels of education had higher rates of TBM. Patients with TBM manifested shortness of breath more frequently than patients without TBM. Patients with TBTB who had undergone bronchoscopic interventions have a higher rate of TBM. Conclusions: Despite mostly adequate anti-tuberculosis chemotherapy, patients with TBTB can present with CASTB involving severe scarring stenosis, bronchial occlusion, tracheobronchomalacia and even destroyed lung.

We present a 67-year-old man with allergic bronchopulmonary aspergillosis (ABPA), whose chest computed tomography (CT) scans showed localized circumferential bronchial wall thickening in the right main bronchus to middle truncus. Chest CT scans showed high-attenuation mucus in the right B8 bronchus. Bronchoscopy showed narrowing of the right main bronchus and inspissated mucus plugging in the right B8 bronchus. Histological examination of the right main bronchus revealed bronchial inflammation with numerous neutrophils and plasma cells. Treatment with corticosteroid and antifungal agents resulted in resolution of the symptoms and right bronchial lesions. The clinical course may indicate that the bronchial lesions were associated with ABPA.
ABSTRACT
Introducción: Se denomina como cáncer de pulmón a un conjunto de enfermedades resultantes del crecimiento aberrante de células del tracto respiratorio, en particular del tejido pulmonar. Objetivo: Determinar los aspectos broncoscópicos e histológicos útiles en la confirmación del diagnóstico de dichas neoplasias malignas. Métodos: Se realizó una investigación descriptiva y transversal de los 346 pacientes atendidos por cáncer de pulmón en el Servicio de Neumología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba durante los años 2016 y 2017, en quienes se realizó broncoscopia. Para ello se utilizaron las variables edad, sexo, técnica diagnóstica empleada, diagnóstico histopatológico, localización más frecuente. Resultados: Predominaron los pacientes en las edades entre los 56 y 75 años (66,1 %), así como el sexo masculino (65,0 %). La biopsia bronquial fue el procedimiento que mayormente reveló la presencia del cáncer (61,3 %) y el tipo histológico más frecuente fue el carcinoma epidermoide (67,8 %). Conclusiones: Se demostró la importancia de la broncoscopia y sus procedimientos diagnósticos para confirmar la existencia del proceso morboso.
Introduction: It is denominated as lung cancer to a group of diseases resulting from the abnormal growth of cells of the breathing tract, in particular of the lung tissue. Objective: To determine the useful bronchoscopic and histologic aspects in the confirmation of the diagnosis of these neoplasms. Methods: A descriptive and cross-sectional investigation of the 346 patients assisted due to lung cancer in the Pulmonology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital was carried out in Santiago de Cuba during 2016 and 2017 to whom a bronchoscopy was carried out. The variables used were age, sex, diagnostic technique used, histopatologic diagnosis and more frequent localization. Results: The patients aged 56 and 75 (66.1 %), as well as the male sex (65.0 %) prevailed. The bronchial biopsy was the procedure that mostly revealed the presence of cancer (61.3 %) and the most frequent histologic type was the squamous cell carcinoma (67.8 %). Conclusions: The importance of bronchoscopy and its diagnostic procedures to confirm the existence of the morbid process was demonstrated.

Inhalation of Foreign Body is one of the most common causes of accidental death at home in the paediatric age group. There may not be a clear history of foreign body inhalation and the patient may be asymptomatic at initial presentation. This coupled with the failure of radiological investigations on most occasions makes this a vexing clinical situation. These apparently normal children almost invariably have a bad prognosis if the foreign body is ignored. This study aims to define the most important factors influencing the decision to carry out the definitive surgery, i.e., bronchoscopy, which can be diagnostic as well as therapeutic, based on our experience with 50 cases of suspected FB in the tracheobronchial tree from January 2001 to July 2003. Results from the study suggest that radiological investigations have only limited value in deciding the management of a patient with suspected Foreign Body inhalation. This should not influence the decision to carry out a bronchoscopy, which should rather be based on history and clinical examination.
