Abstract
PDF - Several methods of physiotherapy have been advanced for benign paroxysmal positional vertigo involving horizontal semicircular canal (HC-BPPV). In this review article, the diagnosis and therapeutic maneuvers for HC-BPPV including recently published several randomized controlled trials are described.

Abstract
PDF
- Objective: The purpose of this study was to identify the clinical characteristics of
horizontal canal benign paroxysmal positional vertigo (h-BPPV) with persistent geotropic
direction changing positional nystagmus (DCPN).
Methods
One hundred thirty two patients diagnosed as the geotropic subtype of h-BPPV were analyzed retrospectively. Patients were classified into two groups: persistent h-BPPV (ph-BPPV) group which means h-BPPV showing persistent (＞1 minute) geotropic DCPN and short duration h-BPPV (sh-BPPV) group that means h-BPPV with short duration (≤1 minute) geotropic DCPN. We compared the clinical characteristics and treatment outcomes between the two groups.
Results
The study included 34 patients with ph-BPPV and 98 patients with sh-BPPV. There were no differences between the two groups in age, distribution of sex and the affected side. The ph-BPPV group had higher secondary BPPV preponderance and dizziness handicap index (DHI) score compared to the sh-BPPV group. The ph-BPPV group required higher number of canalith repositioning procedures (CRPs) until resolution and higher multiple/single CRP ratio than the sh-BPPV group. In addition, the ph-BPPV group showed longer duration until the remission of subjective symptoms (vertigo, dizziness) compared to the sh-BPPV group.
Conclusion
ph-BPPV was more frequently associated with secondary causes of BPPV and demonstrated higher DHI score, total number of CRP, and longer remission duration of subjective symptoms compared to sh-BPPV. This information may be helpful for clinicians in counseling and managing the patients with persistent geotropic DCPN h-BPPV.

Abstract
PDF
- The binding of anti-GD1b IgG antibody to the cerebellar granular area or spinocerebellar Ia fibers in the peripheral nerves may cause the prominent cerebellar ataxia, mild quadriparesis and sensory dominant neuropathy. A 31-year woman presented with severe cerebellar ataxia and prominent apogeotropic positional nystagmus/vertigo. Increased anti-GD1b antibody IgG in her serum was noted. 18F-flurodeoxyglucose positron emission tomography (FDG-PET) showed decreased uptake in cerebellum. It is the first case of central positional nystagmus with anti-GD1b IgG antibody.
