ABSTRACT

BACKGROUND: The aim of this study is to verify if (1) there is a link between hypovitaminosis D and benign paroxysmal positional vertigo, (2) the number of benign paroxysmal positional vertigo relapses decreases after vitamin D supplementation; and (3) benign paroxysmal positional vertigo response to physical therapy improves after hypovitaminosis D correction. METHODS: We enrolled 26 patients with benign paroxysmal positional vertigo and 24 subjects, who never suffered from vertigo, as a control group. All benign paroxysmal positional vertigo patients underwent physical therapy, once a week, until benign paroxysmal positional vertigo resolution. All participants were subjected to a dosage of serum 25(OH) vitamin D. In patients with hypovitaminosis D, we prescribed cholecalciferol. After 3 months of therapy, all patients were asked to undergo a second dosage of serum 25(OH) vitamin D. For each patient, we counted the number of maneuvers required to resolve each episode of benign paroxysmal positional vertigo before and after vitamin D supplementation. RESULTS: Our results suggest that (1) there is a relationship between vitamin D deficiency and the onset of BPPV and (2) hypovitaminosis correction is able to reduce both the number of patients relapsing and the number of relapses per patient. CONCLUSIONS: We have not found a significant effect of vitamin D supplementation as regards the responsivity of benign paroxysmal positional vertigo to physical therapy.

ABSTRACT

We lately reported the cases of patients complaining positional vertigo whose nystagmic pattern was that of a peripheral torsional vertical positional down beating nystagmus originating from a lithiasis of the non-ampullary arm of the posterior semicircular canal (PSC). We considered this particular pathological picture the apogeotropic variant of PSC benign paroxysmal positional vertigo (BPPV). Since the description of the pilot cases we observed more than 150 patients showing the same clinical sign and course of symptoms. In this paper we describe, in detail, both nystagmus of apogeotropic PSC BPPV (A-PSC BPPV) and symptoms reported by patients trying to give a reasonable explanation for these clinical features. Moreover we developed two specific physical therapies directed to cure A-PSC BPPV. Preliminary results of these techniques are related.
