There is compelling evidence that free-floating endolymph particles in the posterior semicircular canal underlie most cases of benign paroxysmal positional vertigo (BPPV). Recent pathological findings suggest that these particles are otoconia, probably displaced from the otolithic membrane in the utricle. ⋯ We describe the various techniques for this manoeuvre, plus treatments for uncommon variants of BPPV such as that of the lateral canal. For the rare patient whose BPPV is not responsive to these manoeuvres and has severe symptoms, posterior canal occlusion surgery is a safe and highly effective procedure.

To examine vestibular system functions in children with episodic vertigo attacks. ⋯ Peripheral vestibular problems in childhood present in a wide spectrum, which varies from a short episode of dizziness to a typical vestibular attack with fluctuating sensory neural hearing loss or episodes of BPPV. A considerable number of these vestibular problems might be related to the migraine syndrome.

Either licensed American chiropractors or traditional Chinese herbalists may produce vertiginous attack in a patient after cervical manipulation. The purpose of the study was to present our experience in treating these patients to determine the risk of this procedure. ⋯ When there are multiple central signs in electronystagmography results or slow blood flow of the vertebral artery is displayed in neck on Doppler sonography or magnetic resonance angiography scan, the therapeutic benefits of cervical manipulation cannot be expected to outweigh its potential risk for the morbidity of cervical vessels.

Randomized Controlled Trial Multicenter Study Clinical TrialBetahistine dihydrochloride in the treatment of peripheral vestibular vertigo.
The present study compares the efficacy and safety of betahistine dihydrochloride to that of a placebo in recurrent vertigo resulting from Meniere's disease (MD) or in paroxysmal positional vertigo (PPV) of probable vascular origin. The design was double-blind, multicentre and parallel-group randomised. Eleven Italian centres enrolled 144 patients: 75 of the patients were treated with betahistine (41 MD/34 PPV) and 69 with placebos (40 MD/29 PPV). ⋯ Associated symptoms and the quality of life also were significantly improved by betahistine. Both the physician's judgement and the patient's opinion on the efficacy and acceptability of the treatment were in agreement as to the superiority of betahistine. The effective and safe profile of betahistine in the treatment of vertigo due to peripheral vestibular disorders was confirmed.
