PURPOSE: To evaluate whether a repeated canalith repositioning procedure (CRP) influences the residual symptoms and the rate of recurrence of benign paroxysmal positional vertigo (BPPV) in patients with post-CRP dizziness. MATERIALS AND METHODS: In this retrospective study, we analyzed 292 patients at the referral center for ENT diseases with a first episode of BPPV treated with a single CRP following clinical practice guidelines. In 178 patients (67.9%) who presented dizziness after BPPV recovery at the follow-up visit, 94 patients underwent CRP (treated group) and 84 did not (non-treated group)...

Residual dizziness (RD) following the resolution of a benign paroxysmal positional vertigo (BBPV) episode is frequently reported by patients. Possible causes are still under debate in the literature. This study discusses the possible role of otolithic function and of elapsed time from onset of symptoms to diagnosis in the genesis of RD. In total, 116 patients younger than 65 years with their first episode of BPPV and without any other comorbidities were enrolled in the study. Before a bedside examination, subjective visual vertical (SVV) was determined in the case of a history suggestive of BPPV...

OBJECTIVE: To analyze the clinical characteristics, prognosis and therapeutic effects of sudden sensorineural hearing loss (SSHL) patients associated with vertigo, and to investigate the strategy of diagnosis and treatment. METHODS: We retrospectively analyzed the clinical characteristics of 240 patients diagnosed as SSHL with vertigo, who were treated in the Chinese PLA General Hospital from July 2008 to August 2012. Various factors affecting the therapeutic effects were analyzed, such as audiological features, vestibular function tests, genders, audiograms, lasting before seeing a doctor, courses of vertigo and vascular factors...

OBJECTIVE: To investigate the diagnosis applying effects of ocular vestibular evoked myogenic potentials(oVEMP) in peripheral BPPV disease. METHOD: During September 2012 to January 2015, we selected 80 healthy people in our hospital medical center as the control group, choose the same period of primary benign paroxysmal positional vertigo as the observation group of 80 patients. Two groups were carried out fully functional auditory evoked potential analysis, determination of oVEMP and cervical vestibular evoked myogenic potentials (cVEMP) anomaly amplitude threshold, P1 latencies, N1 incubation period...

OBJECTIVES: To investigate the role of viral infection in benign paroxysmal positional vertigo (BPPV). METHODS: In this retrospective study, 483 patients with BPPV were included in the study group. The control group consisted of 461 healthy subjects. In both groups, serologic analysis of viral agents (HSV1, HSV2, Herpes zoster, EBV, CMV, adenovirus, influenza, and parainfluenza virus) was performed. RESULTS: With the exception of influenza and parainfluenza, all viral serology values were higher in the BBPV group than the control group...

OBJECTIVE: To investigate the clinical features and vestibular symptoms of patients with abnormal ocular vestibular evoked myogenic potentials (oVEMPs) and/or cervical VEMPs (cVEMPs) in the presence of normal caloric responses. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary referral center. METHODS: One thousand five hundred twenty-one consecutive patients with balance problems who underwent the caloric, cVEMP, and oVEMP tests were included, and patients who showed abnormal oVEMPs and/or cVEMPs in the presence of normal caloric responses were selected...

OBJECTIVE: To compare the clinical presentation and outcome between patients with traumatic-BPPV (t-BPPV) and idiopathic-BBPV(i-BPPV). METHOD: The clinical records of 186 patients with posterior canal BPPV were reviewed retrospectively. All patients were diagnosed using the Dix-Hallpike test and treated with the canalith repositioning procedure. The outcome of patients with t-BPPV was compared with patients with i-BPPV. RESULT: Twenty-three of 186 patients with BPPV fulfilled the diagnostic criteria for t-BPPV...

BACKGROUND: Many patients consult neurologists because of vertigo. Benign paroxysmal positional vertigo (BBPV) is one of the most common types of vertigo. Although the clinical presentation of this common condition is straightforward, the diagnosis and diagnostic maneuvers can be challenging. OBJECTIVES: How useful is the Dix-Hallpike test in establishing the diagnosis of BPPV? How useful is an alternative positional test, such as the side-lying maneuver, in the diagnosis of BPPV? METHODS: We addressed the question through development of a structured critically appraised topic...

BACKGROUND: Although head trauma is considered a common cause of benign paroxysmal positional vertigo (BPPV), clinical presentation and outcome of traumatic BPPV (t-BPPV) have not been systematically evaluated. OBJECTIVES: To compare the clinical presentation, patient's response to physical treatment, and outcome of patients with t-BPPV with those with the idiopathic form (i-BBPV). SETTING: Tertiary referral neuro-otology outpatient clinic...

BACKGROUND: Positioning nystagmus of the peripheral benign type (BPPV) has long been considered to be due to cupulolithiasis-i.e. attachment of inorganic material to the cupula-of the posterior vertical semicircular canal. Meanwhile it has generally been recognized that not all characteristics of this type of nystagmus/vertigo can be explained by assuming a gravity-dependent reaction of the posterior canal. Canalolithiasis-i.e. floating material within the canal, heavier than endolymphe-of the posterior semicircular canal is now widely regarded as the cause of BPPV...

Arkansas bee virus (ABV) is a 30-nm isometric virus composed of one major species of polypeptide (mol. wt. 43 X 10(3] and one species of single-stranded RNA (mol. wt. 1.8 X 10(6]. The size of the genomic RNA and the lack of evidence for encapsidation or synthesis of a second smaller RNA species exclude further consideration of this virus for inclusion with the physicochemically similar viruses of the Nodaviridae. Several independent isolations of ABV were made from bees, and in each case it was associated in mixed infection with a picorna-like virus termed Berkeley bee picornavirus (BBPV)...
