A neuromuscular transmission block produced by a cancer tissue extract derived from a patient with the myasthenic syndrome

The myasthenic syndrome occasionally is associated with bronchogenic carcinoma. The neuromuscular transmission defect in this syndrome is characterized by a reduction of acetylcholine release from motor nerve endings. This paper reports that an acetone extract of cancer tissue from a patient with the syndrome reduces the acetylcholine release from motor nerve endings and produces a neuromuscular transmission defect in the frog nerve-muscle preparation. This suggests that the pathogenic substance(s) contained in the extract may be produced by certain types of bronchogenic carcinoma and may cause the myasthenic syndrome.

La broncho-fibroscopie sous anesthésie générale et ses possibilités

Les auteurs ont rapporté les résultats d’une étude portant sur 559 cas de cancer du poumon étudiés pendant 19 ans de pratique bronchoscopique. Ils notent que dans 116 cas de cancer d’origine périphérique, les techniques bronchoscopiques traditionnelles ne sont pas suffisantes pour faire le diagnostic. Il montrent l’intérêt des examens cytologiques des frottis obtenus par la technique du brossage sélectif de la muqueuse, de la biopsie bronchique par pince et de la biopsie transbronchique à l’aiguille. The authors have reported the results of a study involving 559 cases of lung cancer seen during a 19-year period of bronchoscopic examination. They found that in the 116 cases of cancer of peripheral origin, classic bronchoscopy techniques were not sufficient to establish the diagnosis. The authors point out the importance of cytological examination of smears obtained by selective mucosal brusch biopsy, of transbronchial punch biopsy and of transbronchial needle biopsy.RésuméLes auteurs ont rapporté les résultats d’une étude portant sur 559 cas de cancer du poumon étudiés pendant 19 ans de pratique bronchoscopique.

A cuffed bronchoscope in an emergency haemorrhage in particular

ConclusionIn the preceeding paragraphs, we have described the structure of our cuffed bronchoscope with general anaesthesia and further pointed out the widspread indications of bronchoscopy and reported the important role in an emergency, haemorrhage in particular.In the preceeding paragraphs, we have described the structure of our cuffed bronchoscope with general anaesthesia and further pointed out the widspread indications of bronchoscopy and reported the important role in an emergency, haemorrhage in particular.
