Controlled clinical trial of pentoxifylline versus cinnarizine in the treatment of labyrinthine disorders.

Seventy-six patients with labyrinthine diseases of vascular origin were treated in a 6-week double-blind comparative study with either 400 mg pentoxifylline ('Trental') or 75 mg cinnarizine 3-times daily. Clinical evaluations, supported by audiological tests and vectornystagmography, were carried out before and after treatment. Statistical analysis of the results showed pentoxifylline to be globally superior to cinnarizine and especially to have a more intense antivertiginous effect. No significant differences were observed between the two drugs in respect of tinnitus and hearing loss therapy. Side-effects were occasional, mild and well tolerated in the pentoxifylline group, and more pronounced and frequent with cinnarizine.

The Mondini dysplasia - a clinical study.

The authors describe a clinical approach to the diagnosis and treatment of sensory-neural hearing loss associated to the Mondini dysplasia. The first element of diagnostic suspicion was represented either by a history of fluctuant and progressive hearing loss or by electrocochleography patterns showing multiple-peaked acoustic nerve action potentials similar to those observed in Ménière's disease. Confirmation of the diagnosis was obtained by temporal bone polytomography. An endolymphatic subarachnoid shunt was performed in 22 ears of 18 patients. The results, although preliminary, suggest that the shunt effectively contributes to stabilize the hearing and arrest the further progression of the hearing loss.

Vestibular decruitment. A study of the phenomenon in a normal population.

Vestibular decruitment is a phenomenon characterized by the presence of less intense responses following stronger vestibular stimulation, and its presence has been considered as indicative of central vestibular pathology. In this study conducted in 24 normal individuals, with normal caloric responses, decruitment was observed in 58.3% of the cases. These decruitments were of types I and II as defined by Torok. Type III decruitment was not seen in these patients. In view of the present findings the actual meaning of the phenomenon must be investigated in larger numbers of patients with peripheral or central vestibular disorders.

Flunarizine and cinnarizine as vestibular depressants. A statistical study.

The authors analysed the vestibular depressant activity of flunarizine and cinnarizine, as compared to a placebo, in 58 patients with peripheral labyrinthine disorders. The activity of the medications was judged by the reduction of the average velocity of the slow phase of the post-caloric nystagmus, before and after treatment. In spite of being administered in a smaller dosis, flunarizine appeared to have a more intense vestibular supressant activity, as judged by different statistical tests.
