  • Clinical characteristics of patients with multi-canal benign paroxysmal positional vertigo. [Journal Article]
    Braz J Otorhinolaryngol. 2020 Jun 16 [Online ahead of print]Si L, Ling X, … Yang X
  • CONCLUSIONS: Posterior-horizontal canal benign paroxysmal positional vertigo was the most common type. Multi-canal benign paroxysmal positional vertigo involving anterior canal was also not uncommon. Caloric tests and pure tone audiometry may help in the determination of the affected side. Manual reduction was effective in most of Multi-canal benign paroxysmal positional vertigo patients.
  • Nystagmus in Ramsay Hunt syndrome with or without dizziness. [Journal Article]
    Neurol Sci. 2020 Jun 26 [Online ahead of print]Lee J, Choi B, … Kim CH
  • CONCLUSIONS: Various patterns of nystagmus including direction-fixed and positional direction-changing nystagmus were observed in RHS patients, and inflammation of the vestibular nerve and inner ear end organs may be responsible for the production of nystagmus in these patients. The results support that the evaluation of vestibular function may be necessary even in RHS patients who do not complain of dizziness or vertigo.
  • Transient Neurological Symptoms Preceding Cerebellar Ataxia with Glutamic Acid Decarboxylase Antibodies. [Journal Article]
    Cerebellum. 2020 Jun 26 [Online ahead of print]Muñiz-Castrillo S, Vogrig A, … Honnorat J
  • A prompt diagnosis and treatment of patients with autoimmune cerebellar ataxia (CA) with antibodies against glutamic acid decarboxylase (GAD-Abs) may lead to a better prognosis. Herein, we report prodromal transient neurological symptoms that should raise clinical suspicion of CA with GAD-Abs. We initially identified a 70-year-old man who presented a first acute episode of vertigo, diplopia, and …
  • Evidence of Large Vestibulo-Ocular Reflex Reduction in Patients With Menière Attacks. [Journal Article]
    Otol Neurotol. 2020 Jun 24 [Online ahead of print]Yacovino DA, Schubert MC, Zanotti E
  • CONCLUSIONS: Vestibular function during an attack of MD is a dynamic process associated with fluctuation of the dynamic (hVOR gain) and static (spontaneous nystagmus) processes, which exist in parallel with the perception of vertigo. Our data support vHIT monitoring during an episode to provide objective and accurate evidence of the ear with active disease. This would be particularly useful for those patients with MD presentations of unreliable hearing or assisting to identify the ear to be treated in the case of bilateral MD.
  • Vertical nystagmus as a feature of PIGN-related glycosylphosphatidylinositol biosynthesis defects. [Review]
    Clin Neurol Neurosurg. 2020 Jun 18; 196:106033.Jezela-Stanek A, Mierzewska H, Szczepanik E
  • Vertical nystagmus is a known clinical feature, is however rarely observed in a specific neurodevelopmental disorder. Based on our experience with Polish patients with glycosylphosphatidylinositol biosynthesis defects (GPIBD) due to PIGN variants, supported by literature review, we have verified the clinical significance of this feature in PIGN-related disorder. We hope to underline the clinical …
  • Contralesional subjective visual horizontal predicts endolymphatic hydrops. [Journal Article]
    Acta Otolaryngol. 2020 Jun 18 [Online ahead of print]Nham B, Welgampola MS, Halmagyi GM
  • Background: The subjective visual horizontal (SVH) is a test of utricular function that assesses conjugate ocular torsion which is a component of the ocular tilt reaction (OTR). In unilateral destructive peripheral vestibular lesions, the OTR and so the SVH tilt is usually ipsiversive.Aims/objective: Our study aimed to profile the causes of a contraversive SVH tilt in patients with a confirmed u…
  • Vestibular migraine and benign paroxysmal positional vertigo, close presentation dilemma. [Journal Article]
    Acta Otolaryngol. 2020 Jun 18 [Online ahead of print]Mahrous MM
  • Background: Not only an association between benign paroxysmal positional vertigo (BPPV) and migraine have been recognized in the literature, but also, there are close similarities between BPPV and vestibular migraine (VM) presentations as both can be presented by very similar positional nystagmus.Aims/objectives: To prescribe relatively uncommon cases of positional nystagmus caused by VM that mi…
  • Lateral Semicircular Canal BPPV…Are We Still Ignorant? [Journal Article]
    Indian J Otolaryngol Head Neck Surg. 2020 Jun; 72(2):175-183.Singh J, Bhardwaj B
  • Benign Paroxysmal Vertigo is one of the most common causes of vertigo. The most common semicircular canal involved in pathogenesis of BPPV is Posterior semicircular canal. However anterior and lateral semicircular canals can also sometimes be responsible for BPPV but their involvement in pathogenesis is still underrated. The incidence of lateral semicircular canal BPPV is in literature is around …
  • Case 279: Central-Variant Posterior Reversible Encephalopathy Syndrome. [Journal Article]
    Radiology. 2020 Jul; 296(1):239-243.Abraham P, Longardner K, … Handwerker J
  • HistoryA 25-year-old woman with recently diagnosed systemic lupus erythematosus and class IV lupus nephritis confirmed with biopsy and treated with mycophenolate mofetil presented with a 2-day history of progressively worsening edema of her face and lower extremities. She had no antecedent infection or vaccination. She was admitted to the hospital and treated with methylprednisolone, furosemide, …
  • Neuroanatomical basis of Wallenberg syndrome. [Journal Article]
    Cir Cir. 2020; 88(3):376-382.Gasca-González OO, Pérez-Cruz JC, … Delgado-Reyes L
  • Wallenberg syndrome, or lateral medullar syndrome, is the clinical presentation of the infarct in the territory of posterior inferior cerebellar artery. Its signs and symptoms include vertigo, nystagmus, diplopia, ipsilateral Horner syndrome, facial ruddiness and dry skin, dysphonia, dysphagia, dysarthria, ipsilateral loss of gag reflex, ipsilateral ataxia, ipsilateral impaired taste, ipsilateral…
  • The evaluation of the use of isotretinoin on vestibular system by using vHIT. [Journal Article]
    Am J Otolaryngol. 2020 Jun 02; 41(5):102579.Kocak E, Bozdemir K, … Dikicier BS
  • CONCLUSIONS: Although the studies demonstrating the effect of ISO on cochlea and symptoms occurring during treatment such as nausea, vomiting and vertigo suggest that it may exert effects on peripheral vestibular system, the present study indicates that it has no short terms effects on structures in peripheral vestibular system and vestibuloocular reflex pathways.
