[Melatonin therapeutic use in psychiatry: a 39 year bibliographic study].

INTRODUCTION: The therapeutic uses of melatonin in psychiatry are reviewed. METHODS: Data source and search strategy: a 39 year period search covering a 39 year period (1966-2004) was carried out using Medline data base. The search strategy consisted in the combination of the key words ((mental disorders or psychiatry)) and ((melatonin and therapeutic use)). Two restrictive criteria were applied: a) selection of studies carried out in humans, and b) only randomized controlled trials were admitted RESULTS: 56 articles were found. Twelve were excluded because they were not directly related to the study aim. Melatonin was used in 44 articles related to different clinical conditions. It was used because of its hypnotic and/or resynchronizing actions in 93.2 % of the articles, while in 4.5 % of the articles melatonin was used due to its antioxidant properties. CONCLUSIONS: The main use of melatonin as a therapeutic agent in psychiatry is in sleep disorders and its use in other psychiatric is minor.

[Reactive and adaptive phenomena in bronchial asthma].

Psychological phenomena secondary to bronchial asthma play a relevant role in this disease influencing in a remarkable way its clinical course in each patient. Thus, an appropriate knowledge of the reactive and adjustment phenomena may lead to an outstanding medical outcome in response to the relevant conventional medical treatments usually carried out in these patients. In our present paper diverse psychosological variables involving psychological responders to a chronic disease as bronchial asthma are analysed. Such variables include so important topics as "illness behaviour", "life style", coping style" and treatment compliance in this very clinical condition.

[Incomplete Digeorge syndrome (author's transl)].

A newborn with multiple malformations, recurrent infections and hypocalcemic tetany is presented. The malformations included: Facial asymmetry, micrognathia, epicantus, low set nose, peculiar ears, club-feet and heart disease. The immunologic work-up disclosed a cellular immunodeficiency, but normal humoral immunity, and a diagnosis of "incomplete DiGeorge syndrome" was made. No thymus, nor parathyroid glands were found at autopsy. The disagreement between the analytical data and the pathological findings of "complete DiGeorge syndrome" are discussed. The existence of vestigial ectopic thymus not found in the dissected organs is considered the most likely hypothesis. Finally some considerations are made about a possible role of the rubeola virus on its etiology and the actual therapeutic possibilities.
