[Methodological problems in the induction of exercise-induced asthma in atopic patients].

The considerable discrepancy in results reported by the literature on the question of exercise induced asthma (EIA) poses some methodological problems as regards the standardisation fo such tests. As the variability of the response depends to a great extent on the duration of the physical effort (and, to a smaller extent, on other quality features of the exercise), the importance of being able to deploy an effective, standardised control instrument, with characteristics of simplicity and easy repeatability, is evident. An exercise test with these features is proposed here and significant results in an early sample of ten patients suffering from atopical asthma are reported.

[Broncho-alveolar cancer. Contribution toward a further clinical classification].

The incidence of alveolar bronchiole carcinoma in 1665 histologically verified cases of lung cancer is referred to on the basis of autoptic observations made at the San Luigi Gonzaga Hospital of Orbassano between 1973 and 1979. In agreement with the most recent reviews of the question, a net increase in the absolute values of this form of cancer was confirmed. Reviewing the personal series, stress is laid on the problems of clinico-nosological classification of a.

[Endothoracic Hodgkin's disease. Description of 3 cases with predominantly endobronchial extrinsication].

Three cases of endobronchial lymphogranuloma are reported. The clinical and histological aspects of lung localization of Hodgkin's disease are outlined. Special attention is paid to a case of concomitant broncho-oesophageal involvement of the lymphogranulomatous process and therapeutic problems are reviewed.

[Radiopaque hemithorax, with special reference to scintigraphic methods].

Radioopaque hemithorax is frequently observed. The various situations in which it may occur are examined aetiopathologically, along with the general and specifically radiological methods used for its investigation. Particular attention is given to the employment of radio-isotopes for this purpose and the methods involved.
