[Coronary artery disease observed in general hospitals: ETTIC study. Comparison between trimetazidine and mononitrate isosorbide for patients receiving betablockers]. / L'insuffisance coronaire chronique dans les hôpitaux généraux: registre ETICC. Comparaison entre la Trimetazidine et le Mononitrate d'isosorbide en complément du traitement bêtabloquant.

The extended use of interventional surgery of revascularisation has modified the prognosis and the evolution of ischaemic heart diseases. However, both coronary artery bypass graft and percutaneous transluminal coronary angioplasty failed to make the symptomatic or subclinical ischaemic manifestations of chronic coronary insufficiency disappear. The interest of using betablockers as a first-line therapy was widely demonstrated. However, their combination with another efficient molecule is often necessary. The aim of this trial has been to appreciate the efficiency of the association of a betablocker with either trimetazidine or with isosorbide monoitrate. Hundred and eighty five patients retaining a positive effort test despite 100 mg of atenolol, received in addition, either 60 mg of trimetazidine (93 cases) of 60 mg of isosorbide mononitrate (92 cases) for a two-month period and are then re-evaluated at the end of this period. The ischaemic threshold is delayed in a significant way in both groups (p < 0.0001; trimetazidine +7%, isosorbide mononitrate +10.7%). Twenty-three percent of the exercise tests under trimetzidine and 19% under isosorbide mononitrate become negative after two months of the therapeutic combination. The clinical improvement is even clearer with the disappearance of the angina crisis during the week before the second exercise test in 63% of the cases under trimetazidine and 54% of the cases under isosorbide mononitrate, among the patients who had kept it under atenolol at the inclusion. In conclusion, the combination of a second efficient molecule, trimetazidine or isosorbide mononitrate, brings a functional and objective improvement to patients with insufficient chronic coronary disease not totally controlled using a betablocker, even with high dosage. One should notice two important advantages in favour of the trimetazidine: one is practical due to a better tolerance (lack of cephalalgia), the other is conceptual (use of the complementary metabolic approach of cellular oxygenation rather than the haemodynamic approach of nitrate compounds which are already in concurrency with all other anti-ischaemic molecules).

[Treatment of tooth discoloration in adolescents with mucoviscidosis]. / Traitement des colorations dentaires chez les adolescents atteints de mucoviscidose.

The very high density of adolescents suffering from mucoviscidosis in the North Finistère, and followed at the Roscoff Hélio-Marin Centre, has led the authors to deal with the dental colourations of these patients. The severity this tetracycline, dyschromy, varies with the intake of the medicament. Several therapies are possible, the technique of composite laminate facings is the most used as it adapts particularly well to the cases of these adolescents.
