RESUMEN
Necrotizing sarcoid granulomatosis (NSG) was first described by Liebow in 1973 among the heading "pulmonary angeitis and granulomatosis". We reported four cases of NSG. The diagnostic was made by open lung biopsy in all, and the distinctive features were those described by Liebow: presence of numerous sarcoid-like granulomas, foci of fibrinoid necrosis and granulomatous vasculitis. Clinical, radiological, and clinical course characteristics allow the reasonable conclusion that NSG is the histopathological substratum of a variety of sarcoidosis affections termed "nodular sarcoidosis".

This study deals two cases of operated bronchial muco-epidermoid tumours. They were localized in both cases in the segmentary bronchi (apical ones of lower lobes), one mostly endo-bronchial, the other with an endo-exobronchial development. The histological diagnosis was done after the thorough analysis of the surgical specimen revealed the association of two cell types characteristic of these tumours: mucus producing cells and epidermoid cells. Evolution differs in both cases, as the first observation revealed the existence of a potentially benign tumour, while in the second it behaved like a truly malignant one with local recurrence, regional invasion and distant metastases.

This study was done on a case of segmentary bronchial atresia of the left upper lobe. It is an exceptional congenital malformation, as only 47 observations have been so far recorded. Diagnosis was essentially radiological. The standard chest X ray and tomographies revealed an area of segmentary and lobar transparency surrounding a para-hilar lump. Diagnosis was confirmed by bronchography revealing the lack of injection into the atretic bronchus. Possible infectious complications and the evolution of bronchiectasis and obstructive emphysema justify the surgical exeresis.

The authors studied 24 patients with chronic respiratory insufficiency divided in 2 groups, one of them subjected to long lasting oxygen therapy. They studied the correlations between the variations of hemodynamic and non dynamic parameters registered during a previous assay of oxygen therapy and those observed during the evolution so as to deduct criteria of prescription of a long lasting oxygen therapy. They stress the importance of microcatheterism at the beginning. On the other hand if it suggests the indication for a controlable oxygenation, the ponctual assays of oxygen therapy, such as defined, present no interest where the appreciation of later successes of a long term oxygen therapy is concerned.
