To identify associations between genetic polymorphisms (in the MBL2, TGF-beta1 and CD14 genes) and the severity of the lung disease in patients with cystic fibrosis (CF), as well as between the presence of DeltaF508 alleles and lung disease severity in such patients. ⋯ There was an association between the TC genotype of the T869C polymorphism (TGF-beta1) and mild pulmonary disease in CF patients. In the CD14 gene, the TT genotype seems to be a risk factor for pulmonary disease but is not a modulator of severity. We found no association between being a DeltaF508 homozygote and presenting severe lung disease.

To analyze bronchoalveolar lavage (BAL) specimens of burn victims who inhaled smoke, in order to identify alterations associated with mortality or survival. ⋯ The total body surface area burned was a predictive factor for mortality. Increased numbers of ciliated epithelial cells in the BAL fluid, denoting bronchial epithelial desquamation, were associated with higher mortality in patients with facial burns.
