[IgG4 related disease with exclusive sinonasal involvement: A case report and literature review].

IgG4 related disease (igG4-RD) is a pathological process which integrates a large number of diseases of unknown pathogenesis, considered as being exclusive to many different organs. Diagnosis is established through histological, radiological and serological criteria. Treatment is based on long term corticosteroids; rituximab being used only in refractory cases.

[Assessment of degree of psychological health involvement in pre-laryngectomized patients].

Introduction And Objective: Several authors have found increased anxiety in patients the day before an intervention and its correlation with anxiety levels the post-operative period. In this study, we determined a number of problems to which patients who underwent total laryngectomy often objected: the tracheostomy, being left without a voice and it being an aggressive, major surgery. Our objective was to assess the degree of anxiety and fears of the patient prior to total laryngectomy.

[Utility of bone replacement material in cochlear implant, skull base and sinus surgery: our experience].

Introduction: To solve certain problems that arise in cochlear implant, sinus and skull base surgery, the use of bone cement (PolyBone®) has been introduced in our department. With the goal of making use of surgical bone cements, combining bone growth factors and polyphosphates has allowed the study of these biological materials.

Materials And Results: We present a total of 28 patients aged between 2 and 69 years (mean age of 29.

[Evolution of the tubotympanal mucociliary system activity evaluated with scintigraphy, after ventilation tube insertion in adults with chronic otitis media with effusion].

Introduction And Goals: Tubotympanal mucociliary function is damaged in patients with otitis media with effusion. Our objective was to study its situation and recovery after timopanostomy tube insertion.

Methods: We evaluated the mucociliary activity of the ear and Eustachian tube with scintigraphy in four groups of adults with chronic otitis media with effusion after ventilation tube insertion.

[Study of olfactory function for pyridine in healthy population: influence of variations in humidity].

Objectives: We study the influence of humidity and its variations on human olfactory threshold for pyridine.

Material And Method: Olfactory function was tested on 154 healthy volunteers without rhino-sinusal pathology. Pyridine was used as odorant in four different concentrations investigating the ability to detect the stimulus and the acuity to estimate its intensity.
