All articles undergo a rigorous double-blind review process. CiteScore measures average citations received per document published. Read more. SRJ is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact.

SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. Diseases that involve the medium caliber airways segmental and subsegmental bronchi are common and present clinically with nonspecific respiratory symptoms such as cough, recurrent respiratory infections and occasionally, hemoptysis. The diagnosis can be challenging and the analysis of the regional distribution of the bronchiectasis is the most useful diagnostic guide.

The objective of this manuscript is to describe the main imaging findings of bronchiectasis and their classification, review the diseases that most commonly present with this abnormality, and provide an approach to the diagnosis based on their imaging appearance and anatomic distribution.

Bronchiectasis is a frequent finding that may result from a broad range of disorders. Imaging plays a paramount role in diagnosis, both in the detection and classification, and in the diagnosis of the underlying pathology.. Las bronquiectasias son un hallazgo frecuente, resultado de un amplio espectro de enfermedades.

The epithelium and airway smooth muscles of patients with chronic obstructive pulmonary disease COPD or bronchial asthma undergo certain structural changes that are probably related to increased expression of inflammatory molecules and cell growth factors. Studying the relation between disease and changes in bronchial smooth muscle is difficult if investigation is restricted to samples from autopsies or thoracotomies. This study was designed to evaluate the probability of obtaining bronchial smooth muscle by endoscopic bronchial biopsy in patients with COPD and from individuals with normal lung function, the relation of disease to bronchial epithelial histology, and the potential usefulness of studying airway muscle remodeling events.. Forty-two patients undergoing diagnostic fiberoptic bronchoscopy were enrolled. Bronchial biopsies were taken systematically from the lobar and segmental dividing ridges. The epithelial structure was analyzed by conventional histology.
