ISSN: 0300-2896

Archivos de Bronconeumologia is an international journal that publishes original studies whose content is based upon results of research initiatives dealing with several aspects of respiratory medicine including epidemiology, respiratory physiology, pathophysiology of respiratory diseases, clinical management, thoracic surgery, pediatric lung diseases, respiratory critical care, respiratory allergy and basic research. Other types of articles such as editorials, reviews, and different types of letters are also published in the journal. Additionally, the journal expresses the voice of the following scientific societies: the Spanish Respiratory Society of Pneumology and Thoracic Surgery (SEPAR; https://www.separ.es/), the Latin American Thoracic Society (ALAT; https://alatorax.org/), and the Iberian American Association of Thoracic Surgery (AIACT; http://www.aiatorax.com/).

It is a monthly journal in which all manuscripts are sent to peer-review and handled by the editor or an associate editor from the team and the final decision is made on the basis of the comments from the expert reviewers and the editors. The journal is published solely in English. All the published data is composed of novel manuscripts not previously published in any other journal and not being in consideration for publication in any other journal..

The journal is indexed at Science Citation Index Expanded, Medline/Pubmed, Embase and SCOPUS. Access to any published article is possible through the journal's web page as well as from Pubmed, ScienceDirect, and other international databases. Furthermore, the journal is also present in X, Facebook and Linkedin. Manuscripts can be submitted electronically using the following web site: https://www.editorialmanager.com/ARBR/.

Statistics

Con el fin de precisar el valor de la tomografía computarizada (TC) en el diagnóstico de neumoconiosis complicada o fibrosis masiva progresiva (FMP), se estudiaron de manera prospectiva 127 sujetos que habían trabajado en el interior de minas de carbón durante un período de tiempo superior a 15 años. Tenían neumoconiosis simple (NS) 62 sujetos (profusión nodular ≥ 1/1 según la clasificación internacional ILO-80) en la radiografía simple de tórax y ninguno FMP.

La TC permitió diagnosticar FMP en 8 casos (6,3%; IC 95%: 2,68-11,82). En estos casos la FMP era de categoría A y todos tenían neumoconiosis simple en la radiografía de tórax. De éstos, seis (75%) tenían nodulación q y/o r y cinco (62,5%) tendencia confluente. Estas cifras son significativamente más altas (p < 0,05; test de Fisher) que en el grupo sin FMP, en el que 54 (45,3%) tenían neumoconiosis simple, dos (1,68%) nodulación q y/o r y tres (2,52%) tendencia confluente.

No hemos encontrado diferencias en los valores CVF, VEMS, relación VEMS/CVF y DLCO entre los grupos con y sin FMP.

Estos resultados sugieren que la TC puede ser útil en el diagnóstico de FMP en algunos casos en que ésta se sospeche por hallazgos en la radiografía de tórax (neumoconiosis simple, nodulación q y/o r, tendencia conglomerante).

Tomografía computarizada

To assess the valué of computed tomography (CT) scanning for the diagnosis of complicated pneumoconiosis, or Progressive massive fibrosis (PMF), we conducted a prospective study of 127 subjects who had worked in coal mines for at least 15 years. Sixty-two suffered simple pneumoconiosis (nodular profusión ≥ 1/1 under the ILO-80 international classification System) visible on simple chest films. None were diagnosed of PMF on the basis of x-ray evidence.

CT led to a diagnosis of PMF in 8 cases (6.3%; CI 95%, 2.68-11.82). PMF was category A in all 8; all of them had had chest film evidence of simple pneumoconiosis. Six (75% of these patients had q and/or r nodulation; in 5 (62.5%) the nodules tended to confluence. These figures were significantly higher (p < 0.05, Fisher's test) than in the group of patients with no PMF, among whom 54 (45.3%) had SP, 2 (1.68%) had q and or r nodulation and 3 (2.52%) tended to confluence. We observed no differences in FVC, FEV1, the FEV1/FVC ratio or DLCO between the PMF and non PMF groups.

Our results suggest that CT scans can be useful for diag- nosing PMF in some cases in which it is suspected bases on chest X-ray findings (simple pneumoconiosis, q and/or r nodulation, tendency to confluence).
