Is it important to repeat the positioning maneuver after the treatment for benign paroxysmal positional vertigo?

Introduction: Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular dysfunction.

Objective: To assess whether the performance of the Dix-Hallpike maneuver after the Epley positioning maneuver has prognostic value in the evolution of unilateral ductolithiasis of posterior semicircular canal.

Methods: A prospective cohort study in monitored patients at otoneurology ambulatory with a diagnosis of BPPV; they were submitted to the therapeutic maneuver and then to a retest in order to evaluate the treatment effectiveness; all cases were reassessed one week later and the retest prognostic value was evaluated.

The outcome of patients with Ménières disease.

Unlabelled: Ménière;s disease is a frequent vestibular disease that occurs predominantly in the fourth decade of life. Diagnosis is mostly medical and is based on findings of vertigo, sensorineural hearing loss, tinnitus and aural fullness.

Aim: To study the clinical findings of Ménière;s disease: age, duration of vertigo, tinnitus, hearing loss and aural fullness, and unilateral or bilateral involvement.

Diagnosis of chronic rhinosinusitis in patients with cystic fibrosis: correlation between anamnesis, nasal endoscopy and computed tomography.

Unlabelled: The sinonasal involvement is one of the most common manifestations in cystic fibrosis. Data show a high incidence of chronic rhinosinusitis in these patients. Although it has been found radiographic opacification of the sinus in more than 90% of cases, few are symptomatic.
