Cochlear and Vestibular Functional Study in Patients with Sudden Deafness and Lyme Disease

چکیده
Lyme disease (LD) and idiopathic sudden deafness (ISD) are supposed to be different diseases with different aetiologies. In an attempt to confirm this assumption, 10 patients with confirmed LD and 12 patients with ISD were consecutively included into the study. Further to the laboratory and audio logical investigation, a low frequency sound (LFS) stimulation on posturography was performed and evaluated. Patients with ISD had higher pure tone average (PTA) than patients with LD (PTA ISD/LD was 72 decibel (dB)/23 dB). There was no difference of vertigo between LD and ISD patients. Patients with ISD have more body sway velocity during the first stimulation than patients with LD. We conclude that the cochlear organ is more affected in ISD patients than in patients with LD. However, the vestibular organ seems to be affected in both diseases. ISD and LD are two different disease entities with different aetiologies but with common otological clinical signs.

متن کاملRecovery of cochlear and vestibular function after labyrinthine haemorrhage.
Inner ear haemorrhage is a rare disorder with disabling symptoms. Prognosis is generally considered to be poor with essentially no chance of functional recovery. The most common aetiologies are related to blood dyscrasias, anticoagulant therapy or local trauma. The association with autoimmune diseases is exceptional. The authors report a case of sudden deafness with vertigo in a patient with rh...
متن کاملSudden deafness and anterior inferior cerebellar artery infarction.
BACKGROUND AND PURPOSE Acute ischemic stroke in the distribution of the anterior inferior cerebellar artery (AICA) is known to be associated with vertigo, nystagmus, facial weakness, and gait ataxia. Few reports have carefully examined the deafness associated with the AICA infarction. Furthermore, previous neurological reports have not emphasized the inner ear as a localization of sudden deafne...
متن کاملFailure of Fluid Absorption in the Endolymphatic Sac Initiates Cochlear Enlargement that Leads to Deafness in Mice Lacking Pendrin Expression
Mutations of SLC26A4 are among the most prevalent causes of hereditary deafness. Deafness in the corresponding mouse model, Slc26a4(-/-), results from an abnormally enlarged cochlear lumen. The goal of this study was to determine whether the cochlear enlargement originates with defective cochlear fluid transport or with a malfunction of fluid transport in the connected compartments, which are t...
متن کاملRadixin deficiency causes deafness associated with progressive degeneration of cochlear stereocilia
Ezrin/radixin/moesin (ERM) proteins cross-link actin filaments to plasma membranes to integrate the function of cortical layers, especially microvilli. We found that in cochlear and vestibular sensory hair cells of adult wild-type mice, radixin was specifically enriched in stereocilia, specially developed giant microvilli, and that radixin-deficient (Rdx(-)(/)(-)) adult mice exhibited deafness ...
