The desquamative intersitial pneumonia is a rare, sometimes curable from of diffuse interstitial fibrosis. A clinical, optical and ultrastructural, immunochemical and histo-enzymologic study of one case proved the macrophage nature of the intra-alveolar cells and suggested in the histo-genesis an immunological mechanism depending on lymphocytes.
Prolactin has been lately singled-out among the pituitary hormones, and as such the object of considerable research in the past 15 years. The frequency of prolactin secreting adenomes is established now. The responsibility of iatrogenic factors (neuroleptics, oral contraceptives) in some hyperprolactinaemias is a known fact. The study of the inhibiting dopaminergic system was a landmark in the treatment of hyperprolactinaemia. During the recent Nice Congress, some issues remained unsettled on the physiological activities of prolactin. The matter is clearer when it comes to prolactin secretion. In equilibrium between inhibiting and stimulant factors, the secretion is controlled by the CNS, influenced by the hormonal environment, and its timing is the object of a retrocontrol. This is a very instructive pattern in endocrinology.

Myotonic dystrophy or Steinert's disease may be discovered during acute respiratory failure, sometimes caused by a general anaesthetic. It complicates chronic respiratory failure which is present in almost all cases, both restrictive and obstructive, the clinical signs of which progress with the myopathy. Apart from myotonic degeneration of the respiratory muscles, a hypoventilation syndrome of central origin has been described, but the etiology of this respiratory failure is dominated by repeated aspiration pneumonia favoured by constant dysphagia and passage of food into the trachea and poor cough reflex. One should attempt to correct this.
