ABSTRACT
The conventional hearing aid has benefited from the progress made in electronic miniaturization and digital signal processing. The prescriber should be familiar with these improvements, the anatomic and acoustic limitations related to hearing aids, the possibilities of surgical rehabilitation, as well as the indications for other auditive rehabilitation techniques (bone conduction hearing, middle ear implant, and cochlear implant). A hearing aid should be prescribed within a precise context taking into account patient history, clinical examination, audiometric testing, and choice of the device. Optimal management of a hearing device for a child should be conducted within an adapted network including a specialized ENT physician, audiophonology, a qualified hearing prosthetist, a speech therapist, etc.).

The aim of this randomised, cross-over trial was to compare the gastroduodenal tolerability and anti-aggregating effect of effervescent calcium carbasalate (ECC equivalent to 160 mg aspirin) given once daily either in the morning or in the evening. Twelve healthy volunteers received calcium carbasalate for 2 periods of 5 days (21 days of wash-out between the 2 periods). The principal criterion was the gastroduodenal tolerability assessed by the total number of lesions at upper gastro-intestinal endoscopy. The same treatment-blinded endoscopist performed all evaluations. Efficacy was evaluated by thromboxane B2 measurement and collagen-induced platelet aggregation tests. No difference was observed between morning and evening administration of ECC on gastroduodenal tolerability and platelet agregation. ECC was very well tolerated as assessed by upper gastrointestinal endoscopy and almost totally inhibited platelet aggregation.
