[Malignant transformation of inverted papilloma of the nasal sinuses.. Apropos of a series of 7 cases].

Seven cases of malignant inverting papillomas are presented (6 men and 1 woman) with ages ranging from 31 to 72 years (mean age: 58 years); the minimum follow up was 37 months. The diagnosis was based on the histopathologic analysis of biopsy in five patients. In two patients the diagnosis was confirmed by the pathological analysis of the specimen. Treatment was always surgical: lateral rhinotomy and total ethmoidectomy. Neoadjuvant chemotherapy was given to four patients. Post operative radiation therapy was delivered in five patients. Five patients on seven died: local recurrence and systemic metastases: 3; systemic metastases: 1; second primary: 1. Reports from the literature are discussed. The authors emphasize the treatment modalities based on complete tumor removal through lateral rhinotomy.

[Contribution of L lactate and amino-acid enzymatic biosensors for the analysis of Frey syndrome].

Twelve patients with Frey's syndrome after total parotidectomy for plemorphic adenoma were analysed using simultaneously 2 biosensors. Biosensors allowed for detection of L lactate and amino acid level on intact skin. The assay procedure and the results achieved with the simultaneous use of these 2 biosensors are presented. The L lactate biosensor appears to be an interesting tool for Frey's syndrome analysis. The sensibility of the amino acid biosensor is not sufficient enough to allow its use at time of Frey's syndrome analysis.

[Laryngostroboscopy].

Videostroboscopy has become an essential examination for the assessment of vocal function. The authors describe and review the development of this technique with an analysis and discussion of its indications and results.

[Acoustic distortion products. Clinical values and limitations in the study of low frequencies].

Distortion products are otoemissions produced when the cochlea is stimulated by two pure, continuous sounds f1 and f2. The most ample distortion product in Man corresponds to a frequency of 2f1-f2. The aim of our work is to appreciate the possibilities to study the distortion products for the exploration of low frequencies in Man. Three populations of subjects have been studied: young subjects have been studied: young subjects with a normal hearing, subjects with pathological otoscopic findings in spite of a normal hearing, subjects with pathological otoscopic findings in spite of a normal audiometric study, and subjects with endocochlear perceptive deafness. The major result of this study was to demonstrate that the lowest frequency that can be explored with distortion products is 750 Hertz.
