[Effects of beta blockaders on ventilatory function in chronic bronchitis].

This study was carried out to determine whether beta blockers could be prescribed for patients with coronary insufficiency and chronic bronchitis. The effects of intravenous infusions (30 mn) of propranolol (30 micrograms/kg), practolol 90 micrograms/kg), atenolol (90 micrograms/kg) and acebutolol (150 micrograms/kg) on vital capacity and expiratory flow rates were investigated in chronic bronchitics. Propranolol (n = 51) moderately reduced the vital capacity and FEV1, by an average 9% and a maximum of 20%. The three other infused agents given to groups of 10 patients did not change the ventilatory function. When the same patients were investigated by cross over with propranol bronchoconstriction was observed. This effect was seen in all stages of chronic bronchitis but was much less severe than in a group of 50 asthmatic patients (-23%). The respiratory tolerance of the cardioselective beta blockers seems to be better but there is considerable individual variation and the diagnosis between asthma and chronic bronchitis may itself be very difficult.

[Symptomatology in 162 patients with spasmophilia (chronic idiopathic or constitutional tetany). A statistical analysis using a computer (author's transl)].

A computer was used for a statistical analysis of the results of treatment in 162 patients (130 women and 32 men with an average age of 29 years), with chronic idiopathic tetany. Symptoms leading to diagnosis were mainly feelings of ill-health (27.2 %), motor disorders (19.7 %), and sensory problems (19.1 %). The onset of acute attacks is related, more especially, to psychogenic factors. The frequency of the various clinical manifestations, and their symptomatic grouping were analyzed. The clinical profile is similar in both sexes apart from 7 of the 89 items: lipothymia, abnormal feelings of warmth, pseudo-contraction of the larynx, abnormalities of the exoskeleton, and digestive disorders are more frequent in women, while precordalgia is more often present in men. Factorial analysis of correspondence between 38 variables reveals a very large dispersion of the variables, as the first three factors, which are the most significant, supply only 30% of the total information. Furthermore, very few variables share significant relationships in each factor. In spite of the amount of information collected, this dispersion of the symptomatology does not permit the definition of one or more profile-types of spasmophilia.

[Asthma and propranolol].

The authors report the results of a study of propranolol perfused intravenously at a dose of 1 mcg/kg/mn during 30 mn to 50 asthmatic patients. The VC decreased by 8.3 and by 10.9% in the middle and at the end of the perfusion. The FEV1 decreased by 18.3 and 23% concomitantly. Classifying patients in 4 groups according to the clinical severeness of the asthma showed that the response to propranolol increased with that severenesse. Exploration of obstructive bronchopneumopathies by propranolol provided valuable data or the differential diagnosis of asthma and chronic bronchitis.

[Chronic mediastinitis].

Although unfrequent, chronic mediastinites are not exceptional. Their clinical polymorphism results from diversity of the mediastinal content. The superior vena cava syndrome is the most frequent clinical sign. The essential examination is the angiopneumography. Mediastinitis can be associated to other fibrinogenous processes, particularly the retroperitoneal ones. Infectious processes (tuberculosis, various bacteria), parasitic or medicinal (methysergide), are found in the etiology of this affection. Very often the etiological research is negative: recurring lymphotropic respiratory infections appear responsible for these cryptogenetic chronic mediastinites. Surgery is debatable in case of a superior vena cava syndrome. Anti-tuberculous treatment is efficient against related affections.

[Evaluation of an analgesic activity in man: thermodolorimetery].

The authors propose an experimental technique which makes possible the evaluation in man of the activity of analgesic or anti-inflammatory medications. The principle of thermodolorimetre threshold of painful thermic sensitivity (S.S.T.D. in the french text) which is stable over a period of time in a given individual receiving a placebo but which varies in a significant fashion in groups treated with a medication belonging to one of the two classifications studied.
