[Diagnosis of lung cancer. Fluorescence bronchoscopy]

International audienceAutofluorescence endoscopy is used for more than ten years as an help to the diagnosis of bronchial precancerous lesions and early lung cancers. The technique has been extensively evaluated during the past decade including in two recent randomized studies versus conventional endoscopy that have shown an improvement for the localisation and the diagnosis of high grade precancerous lesions from 2 to 5 times. This paper reviews the principal applications and results of the use of autofluorescence endoscopy in high risk individuals, as well as innovative endoscopic approaches using the fluorescence properties of the respiratory tract

[Acute encephalopathy after infusion of paclitaxel]

International audienceINTRODUCTION: Paclitaxel is an anti-neoplastic agent commonly used in the treatment of primary bronchial carcinoma and tumours of the breast and ovary. Its toxicity, haematological and peripheral neuropathy, are well known. On the other hand central nervous system toxicity is rare. CASE REPORT: We report a case of acute encephalopathy, occurring eight hours after infusion of Paclitaxel, in a patient treated for adenocarcinoma of the lung. It included drowsiness, confusion and hallucinations, and resolved completely after ten days. The diagnosis of encephalopathy secondary to Paclitaxel injection was reached after exclusion of other possible aetiologies. CONCLUSIONS: Acute encephalopathy is a rare complication of intravenous Paclitaxel treatment. The pathophysiology of this toxic effect is discussed: a direct toxicity of Paclitaxel or of its solvent (polyoxethylated castor oil), and the role of a pre-existing alteration of the blood-brain barrier
