Review Case Reports[Localized tracheobronchial amyloidosis. The usefulness of computed tomography].
Tracheobronchial amyloidosis is the most common form of localized bronchopulmonary amyloidoses, although its diagnosis is rare in daily practice. We describe two new cases of localized tracheobronchial amyloidosis, one in the form of a single node and one diffuse. We discuss in particular the contribution of computed axial tomography, mainly for diagnosing the diffuse form, in which a finding of a thickened tracheobronchial wall and intraluminal nodes should lead to the suspicion of this entity. The treatment of choice in most cases is resection with an Nd-YAG laser.

Two cases of traumatic pulmonary pseudocysts in young patients are presented. Blunt chest injuries resulting from traffic accidents were the causes in both cases. ⋯ In both cases, self-limited hemoptysis preceded the appearance of an air-fluid level on X-rays. The diagnoses of pulmonary pseudocyst were made after excluding other possible cause and the outcomes were satisfactory after treatment of symptoms and associated lesions.

Fiberoptic bronchoscopy is at present an indispensable technique in pediatric pulmonology. Sixty-nine such procedures were performed at our center between April 1993 and November 1994 on children under 14 years-old. We used an Olympus BF-3C20 fiberoptic bronchoscope, after providing sedation with diazepam or midazolam, sometimes accompanied by fentanyl and atropine. ⋯ The endoscopic findings were upper airways disease (8.6%), bronchial disease (52.17%), extrinsic bronchial compression (4.34%) and normal (13.04%). Samples were taken in 52.17%. No important complications occurred but there were slight decreases in oxygen saturation.
