Acute vestibulopathy.

The presentation of acute vertigo may represent both a common benign disorder or a life threatening but rare one. Familiarity with the common peripheral vestibular disorders will allow the clinician to rapidly "rule-in" a benign disorder and recognize when further testing is required. Key features of vertigo required to make an accurate diagnosis are duration, chronicity, associated symptoms, and triggers.

[Clinical value of dynamic posturography in the evaluation and rehabilitation of vestibular function of patients with benign paroxysmal positional vertigo].

Objective: To explore the clinical value of dynamic posturography in the evaluation and rehabilitation of vestibular function of patients with benign paroxysmal positional vertigo (BPPV).

Methods: A total of 48 patients with BPPV of posterior semicircular canal in vertigo clinic of our hospital from May 2007 to December 2008 were retrospectively analyzed in this study. All patients underwent the inspection of caloric test, static posturography, and dynamic posturography.

Management of benign paroxysmal positional vertigo with the canalith repositioning maneuver in the emergency department setting.

Vertigo is a common clinical manifestation in the emergency department (ED). It is important for physicians to determine if the peripheral cause of vertigo is benign paroxysmal positional vertigo (BPPV), a disorder accounting for 20% of all vertigo cases. However, the Dix-Hallpike test--the standard for BPPV diagnosis--is not common in the ED setting.

Effect of the canalith repositioning procedure on subjective visual horizontal in patients with posterior canal benign paroxysmal positional vertigo.

Conclusion: Substantial numbers of patients with posterior canal benign paroxysmal positional vertigo (p-BPPV) have signs of utricular dysfunction at baseline. This improves after performing the canalith repositioning procedure.

Objective: To evaluate the changes of subjective visual horizontal (SVH) in patients with p-BPPV before and after treatment with the canalith repositioning procedure.

Canalith repositioning variations for benign paroxysmal positional vertigo.

Objective: To determine if variations in common treatments for benign paroxysmal positional vertigo (BPPV) affected efficacy.

Study Design: Prospective, pseudo-randomized study.

Setting: Outpatient practice in a tertiary care facility.

Dizziness: a diagnostic approach.

Dizziness accounts for an estimated 5 percent of primary care clinic visits. The patient history can generally classify dizziness into one of four categories: vertigo, disequilibrium, presyncope, or lightheadedness. The main causes of vertigo are benign paroxysmal positional vertigo, Meniere disease, vestibular neuritis, and labyrinthitis.

[Meta-analysis on the efficacy of Epley's manoeuvre in benign paroxysmal positional vertigo].

Introduction: Benign paroxysmal positional vertigo (BPPV) is one of the most common conditions that cause the physiognomy of peripheral vertigo.

Objective: To evaluate the effectiveness of Epley's manoeuvre (EM) in the treatment of BPPV using a critical review of the medical literature and a meta-analysis.

Methods: Searches were made in the databases of MEDLINE (PubMed), in the Cochrane collection (Cochrane Register of controlled studies), BIREME and LILACS (all of them up to December 2008).

Assessing vestibular dysfunction. Exploring treatments of a complex condition.

In summary, patients with BPPV can be treated with the canalith repositioning maneuver. Patients with unilateral vestibular hypofunction can be treated using adaptation, substitution, and/or habituation exercises. Patients with motion sensitivity can demonstrate improved tolerance to motion after performing habituation exercises.

Benign paroxysmal positional vertigo.

Benign paroxysmal positional vertigo (BPPV) is characterized by brief recurrent episodes of vertigo triggered by changes in head position. BPPV is the most common etiology of recurrent vertigo and is caused by abnormal stimulation of the cupula by free-floating otoliths (canalolithiasis) or otoliths that have adhered to the cupula (cupulolithiasis) within any of the three semicircular canals. Typical symptoms and signs of BPPV are evoked when the head is positioned so that the plane of the affected semicircular canal is spatially vertical and thus aligned with gravity.

Canalithiasis of the anterior semicircular canal (ASC): treatment options based on the possible underlying pathogenetic mechanisms.

Benign paroxysmal positional vertigo (BPPV) of the anterior semicircular canal (ASC) is an uncommon disorder currently diagnosed with the Dix-Hallpike (D-H) examination. According to the literature, nystagmus and vertigo may be more pronounced when the affected ear is either up or down. In some patients, both right and left D-H tests can trigger nystagmus with the same direction.

Clinical inquiries. What is the best approach to benign paroxysmal positional vertigo in the elderly?

A canalith repositioning maneuver (CRM), such as the Epley or Semont maneuver, should be the first-line treatment for benign paroxysmal positional vertigo (BPPV) in the elderly. Following the Epley maneuver with self-treatment at home using a modified Epley procedure improves outcomes. Postural restrictions are not necessary after CRM treatment.

Long-term follow-up of patients with posterior canal benign paroxysmal positional vertigo.

Conclusions: Recurrence of posterior canal benign paroxysmal positional vertigo (PC-BPPV) developed in one-third of patients when followed for an average of 5 years from diagnosis. History of head trauma and Ménière's disease contributed significantly to recurrence (p < 0.05).

Takotsubo cardiomyopathy and canalith repositioning procedure for benign paroxysmal positional vertigo.

Background: Takotsubo cardiomyopathy, also known as left ventricular apical ballooning syndrome, ampulla cardiomyopathy, or transient left ventricular dysfunction is characterized by chest pain, electrocardiographic changes, transient left ventricular apical aneurysm, and normal coronary arteries. Takotsubo is a round-bottomed, narrow-necked Japanese octopus trap and lends its name to takotsubo cardiomyopathy because of its resemblance to echocardiographic and ventricular angiographic images of the left ventricle in this condition. This appearance takes its source from peculiar, transient regional systolic dysfunction involving the left ventricular apex and mid-ventricle with hyperkinesis of the basal left ventricular segments.

Model experiments of otoconia stability after canalith repositioning procedure of BPPV.

Conclusion: Postural restrictions are probably not necessary after the canalith repositioning procedure (CRP).

Objectives: Epley reported the effect of CRP for benign paroxysmal positional vertigo (BPPV). After CRP, patients are often requested to restrict postural change.

Clinical management of a patient with chronic recurrent vertigo following a mild traumatic brain injury.

Vertigo, was provoked and right torsional up-beat nystagmus was observed in a 47-year-old patient when she was placed into the right Hallpike-Dix test position using infrared goggle technology. The clinical diagnosis was benign paroxysmal positional vertigo (BPPV), specifically right posterior canalithiasis, resulting from a mild traumatic brain injury (TBI) suffered approximately six-months earlier. Previous medical consultations did not include vestibular system examination, and Meclizine was prescribed to suppress her chief complaint of vertigo.

Disconnect between charted vestibular diagnoses and emergency department management decisions: a cross-sectional analysis from a nationally representative sample.

Objectives: The most common vestibular disorders seen in the emergency department (ED) are benign paroxysmal positional vertigo (BPPV) and acute peripheral vestibulopathy (APV; i.e., vestibular neuritis or labyrinthitis).

Benign paroxysmal positional vertigo recurrence and persistence.

Unlabelled: Benign paroxysmal positional vertigo (BPPV) is one of the most common vestibular disorders.

Aim: To study the recurrence and persistence of BPPV in patients treated with canalith repositioning maneuvers (CRM) during the period of one year.

Study Design: longitudinal contemporary cohort series.

[Clinical study of benign paroxysmal positional vertigo recurrence].

Objective: To investigate the cause of recurrence and clinical significance in benign paroxysmal positional vertigo (BPPV).

Method: By retrospectively analyzing the clinical data and results of TCD, CT or MRI of head of 65 patients with non-recurred BPPV and 44 patients with recurred BPPV in 2 years after successful canalith repositioning maneuver.

Result: The prognosis of BPPV shows significant correlated with age, family history, migraine history, intracranial arterial and carotid stenosis and stroke history.

Are postural restrictions after an Epley maneuver unnecessary? First results of a controlled study and review of the literature.

Objective: Postural restrictions after canalith repositioning maneuvers (CRM) for benign paroxysmal positional vertigo of the posterior semicircular canal (p-BPPV) have no proven value and therefore most physicians regard them as unnecessary. The aim of this study was to assess the short-term efficacy of head and body movement limitations after a single Epley maneuver. A review of the literature was performed to assess the current level of evidence for the efficacy of postural restrictions.

Balance in posterior and horizontal canal type benign paroxysmal positional vertigo before and after canalith repositioning maneuvers.

Benign paroxysmal positional vertigo (BPPV) is characterized by acute, brief and rotatory vertigo attacks provoked by changes in head position. Most patients complain of a loss of equilibrium and unstable gait during and between the vertigo attacks. Canalith repositioning maneuvers (CRM) relieve attacks and improve postural stability.
