Bronchiolitis obliterans is an anatomical lesion with multiple aetiologies. In the lung transplant patient the pure forms of bronchiolitis obliterans are probably the consequence of a process of chronic rejection; in fact necropsy tissue or lungs removed which have been transplanted show that the lesions of bronchiolitis obliterans are often associated with parenchymal disorders, vascular and proximal bronchial disease, which are sequelae of phenomena of rejection or infection. The effect of bronchiolitis obliterans on lung function is constant; this may appear progressively or in stages. ⋯ It is exceptional to achieve the diagnosis of bronchiolitis obliterans from the examination of a transbronchial biopsy. It is a combination of features, both clinical and respiratory function, negative bacteriology and virological investigations as well as the absence of any efficacy of conventional treatment for rejection which leads to the diagnosis. In certain cases the question of a pulmonary re-transplantation is raised.

The main primary pollutants released into the atmosphere are sulfur dioxide (SO2), nitrogen monoxide and dioxide (NOx), particulate dust and in a less important part carbon monoxide (CO), hydrocarbons and heavy metals (Pb, Cd). Sulfur and nitrogen oxides are released from combustion of coals and fuels. Sulfates, nitrates and ozone are secondary pollutants resulting from chemical reactions within the atmosphere. ⋯ Since most of these studies do not include bacteriologic and virologic confirmation, it is unclear whether this respiratory morbidity is due to respiratory irritation or infection. In conclusion, we think that high concentrations of air pollutants are very likely to increase sensibility to respiratory infections in humans. There are however no sufficient data to clearly establish whether air pollution constitutes a risk factor for respiratory infections at usual ambient concentrations.

We report a case of patient presenting with a very large pulmonary metastasis which revealed a previously unrecognised uterine epithelioid leiomyosarcoma. This is a rare tumour with a poor prognosis. The treatment of both the primary tumour and the metastasis was surgical.

Respiratory diseases are known to have consequences on health status. The objective of this study was to assess the quality of life of subjects with obstructive respiratory disorders coming for preventive medicine examinations. We conducted a study on a sample of adults living in agricultural areas (n = 1,235). ⋯ In case of airway obstruction, there is no major consequences on health profile. Subjective health measurements are interesting tools in subjects with non-chronic diseases. They can be associated with medical questionnaires because they give complementary inquiries.
