Comparative study of the effectiveness of the surgical technique with and without preservation of the conchal cartilage in otoplasty through the measure of the cephalo-auricular and scapho-conchal angles.

Objectives: Prominent ear abnormalities affect 5% of the population. A prospective, double-blind study of patients who underwent otoplasty procedures to correct these abnormalities was conducted to compare two surgical techniques. They diverge by the preservation or not of conchal cartilage.

Pole-Zero REM Modeling with Application in EEG Artifact Removal.

A new approach of pole-zero modeling in the presence of white noise is proposed. While the model estimate is calculated through the conventional least square estimation, the choice of number of poles and zeros in this scenario is critical and a challenging task. A wrong choice can overfit the additive noise in larger orders or underfit and discard parts of the noiseless data in smaller orders.

[Arguments for early treatment of refractory schizophrenia].

The authors, taking up their experience and the literature, attempt to view the precociousness of alternative, classical neuroleptic treatments in schizophrenia, from notion of treatment-resistant schizophrenia, precocious refractory and intolerance. Until now, clozapine was administrated to patients lasting resistant and in mainly cases hospitalized since many years. As such as quality of life and economy of health, it would be desirable to quickly think of alternatives neuroleptic's therapeutic protocols and clozapine in the treatment-resistant schizophrenias or those presenting an intolerance.
