[Relationship between expiratory muscle dysfunction and dynamic hyperinflation in advanced chronic obstructive pulmonary disease].
Dynamic hyperinflation (DH) and expiratory flow limitation (EFL) are physiologically linked and seem to be involved in the genesis of dyspnea and the quality of life (QL) impairment in chronic obstructive pulmonary disease (COPD). Advanced COPD patients often show expiratory muscles dysfunction that could be involved in DH development. ⋯ In advanced COPD a poorer expiratory muscles endurance is related with higher DH during exercise (and lower EFL), which is correlated with higher dyspnea and worse QL.

Case Reports[Familial pulmonary fibrosis in 2 Mexican sisters with Hermansky-Pudlak syndrome].
Hermansky-Pudlak syndrome is an autosomal recessive disorder commonly found in individuals of Puerto Rican ancestry. We present 2 cases of familial pulmonary fibrosis in 2 Mexican sisters with Hermansky-Pudlak syndrome. Pulmonary fibrosis was biopsy-proven in 1 of the patients. This report shows that Hermansky-Pudlak syndrome may occur in individuals of Mexican ancestry.

Case Reports[Hypersensitivity pneumonitis caused by Mucor species in a cork worker].
Suberosis is a type of hypersensitivity pneumonitis caused by exposure to cork proteins and molds such as Aspergillus fumigatus and Penicillium frequentans. We present the case of a man with suberosis caused by Mucor species, a mold that has been rarely reported to cause hypersensitivity pneumonitis. ⋯ A diagnosis was made on the basis of bronchoalveolar lavage and transbronchial biopsy findings. Mucor species was identified as the causative agent using a specific bronchial challenge test.
