Epley Maneuver (canalith repositioning) for Benign Positional Vertigo.

Acad Emerg Med 2020 Apr 13. Epub 2020 Apr 13.

Department of Emergency Medicine, Kings County Hospital Center, Brooklyn, New York, United States.

Benign paroxysmal positional vertigo (BPPV) is one of the most common causes of vertigo, and is thought to be caused by free-floating debris primarily in the posterior semicircular canal. The condition is usually brought on by a rapid change in head position, and diagnosis can be confirmed by a positive Dix-Hallpike test (DHT). The Epley maneuver was invented as a way to move the ear debris out of the semicircular canal, and involves a series of four sequential movements. Read More

Approaching Acute Vertigo With Diplopia: A Rare Skew Deviation in Vestibular Neuritis.

Mayo Clin Proc Innov Qual Outcomes 2020 Apr 9;4(2):216-222. Epub 2020 Mar 9.

Department of Neurology, University of Illinois College of Medicine at Peoria.

Evaluating the patient with acute constant vertigo or diplopia can be a daunting task for clinicians, who recognize that such symptoms can be the manifestation of potentially devastating disorders like stroke but may be uncomfortable eliciting and interpreting the key symptoms and subtle signs that distinguish dangerous from benign causes. We present a novel and highly instructive case of a patient with acute vertigo and binocular diplopia from a large skew deviation due to vestibular neuritis. As the case unfolds, text and video commentary guide the clinician through the important elements of the history, bedside examination, and laboratory evaluation necessary for accurate diagnosis in the acute vestibular syndrome.

Pseudo-Benign Paroxysmal Positional Vertigo: A Retrospective Study and Case Report.

Front Neurol 2020 24;11:187. Epub 2020 Mar 24.

Department of Otolaryngology, Shandong Provincial Hospital Affiliated to Shandong University, Jinan, China.

Pseudo-benign paroxysmal positional vertigo (pseudo-BPPV) is a specific type of vestibular migraine disguised as benign paroxysmal positional vertigo, which is characterized by recurrent different types of positional and atypical positional vertigo with migraine features. It is easy to be misdiagnosed with BPPV at the first visit, which means that the ideal therapeutic effects are not achieved. Twenty-five cases of pseudo-BPPV with frequent changing positional vertigo were retrospected and the following key features help to identify the disease: recurrent positional and atypical positional vertigo, migrainous accompanying symptoms or migraine history, mild or indistinctive headaches, with or without impaired vestibular function, ineffective for simply reposition.

Is drug consumption correlated with benign paroxysmal positional vertigo (BPPV) recurrence?

Eur Arch Otorhinolaryngol 2020 Jun 20;277(6):1609-1616. Epub 2020 Feb 20.

ENT and Head Neck Surgery Department, Catholic University, Rome, Italy.

Background: Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vertigo and its recurrence is fairly common. Several studies correlated the pathophysiological role of different comorbidities-such as diabetes, osteoporosis, vascular, psychiatric and autoimmune diseases-in the development and recurrence of BPPV. The aim of this study is to analyse the pharmacological history of patients with idiopathic BPPV in relation to the risk of developing recurrence. Read More

Combination of head-up sleep and vertical recognition training may cure intractable motion-evoked dizziness with unknown origin.

Acta Otolaryngol 2020 Feb 18:1-6. Epub 2020 Feb 18.

Department of Otolaryngology-Head and Neck Surgery, Nara Medical University, Kashihara-City, Japan.

It has been reported that head-up sleep (HUS) prevents free-floating otoliths from entering canals and that vertical recognition training (VRT) promotes vestibular compensation. We would like to assess HUS and VRT for intractable motion-evoked dizziness, including possible benign paroxysmal positional vertigo (BPPV). 162 patients diagnosed with intractable motion-evoked dizziness of unknown origin were enrolled and randomly divided into the following four groups: HUS-/VRT-, HUS+/VRT-, HUS-/VRT+, and HUS+/VRT+.

Simultaneous Presentation of Benign Paroxysmal Positional Vertigo and Meniere's Disease - Case Report.

Open Access Maced J Med Sci 2019 Nov 14;7(21):3626-3629. Epub 2019 Oct 14.

University Clinic of Ear, Nose and Throat, University Campus "St. Mother Theresa", Skopje, Republic of Macedonia.

Background: Benign paroxysmal positional vertigo (BPPV) is one of the most common clinical entities, which develops spontaneously in most of the cases, but it can be secondary as a result of different conditions such as head injuries, viral neurolabyrinthitis, Meniere's disease and vertebrobasilar ischemia. The aim of presenting this case is to point out to the need of taking a precise clinical history and performing Dix-Hallpike manoeuvre in all patients who complain about vertigo regardless of the previously diagnosed primary disease of the inner ear.

Case Presentation: A 63-year-old female patient presented with the classical triad of symptoms for Meniere's disease (fluctuating sensorineural hearing loss in the right ear, tinnitus and fullness in the same ear and rotary vertigo), two years later complained of brief episodes of vertigo linked to changes in head position relative to gravity.
