Anterior semicircular canal benign paroxysmal positional vertigo and positional downbeating nystagmus.

Purpose: The aim of this study was to describe the clinical features and video-oculographic findings in patients with anterior semicircular canal benign paroxysmal positional vertigo (BPPV).

Study Design: This is a prospective case series.

Setting: The study was set at an outpatient clinic in a general hospital.

Long-term outcome and health-related quality of life in benign paroxysmal positional vertigo.

A prospective cohort study was designed to evaluate the long-term outcome and health-related quality of life (HRQoL) in patients with posterior canal benign paroxysmal positional vertigo (PC-BPPV) treated by the particle repositioning maneuver (PRM) in the outpatient clinic of a general community hospital. Fifty individuals with PC-BPPV were included, and 45 (90%) completed the study. The diagnosis was based on the history of short episodes of vertigo and a positional nystagmus during the Dix-Hallpike test (DHT).

Health-related quality of life in patients over sixty years old with benign paroxysmal positional vertigo.

Background: Benign paroxysmal positional vertigo (BPPV) is a common cause of dizziness within the geriatric population causing disability. The diagnosis is established by the position-induced rotatory nystagmus, related to the involved ear, demonstrated by the Dix-Hallpike test (DHT). Although the Epley's modified manoeuvre, or particle respositioning manoeuvre (PRM), is an effective treatment for this disorder, its impact on health outcome in patients over 60 years old is unknown.

Impact of treatment on health-related quality of life in patients with posterior canal benign paroxysmal positional vertigo.

Objective: To determine the impact of the particle repositioning maneuver on posterior canal benign paroxysmal positional vertigo-related quality of life using the Medical Outcomes Study 36-Item Short Form Health Survey and the Dizziness Handicap Inventory Short Form.

Study Design: Prospective, consecutive new cases of posterior canal benign paroxysmal positional vertigo.

Setting: Ambulatory, primary referral hospital.

Position in bed is associated with left or right location in benign paroxysmal positional vertigo of the posterior semicircular canal.

Purpose: To determine if position during bedrest is related to the canal affected in posterior canal benign paroxysmal positional vertigo (BPPV).

Materials And Methods: Fifty-five individuals with posterior canal BPPV were investigated. Diagnosis was established if a consistent clinical history was found with vertigo and induced positional nystagmus elicited on the Dix-Hallpike test (DHT).
