Symptoms and signs in 22 patients with vestibular paroxysmia.

•Up until now, there is no diagnostic gold standard for vestibular paroxysmia, leading to many diagnoses made by exclusion of other (more frequent) episodic vestibular pathologies such as benign paroxysmal positional vertigo, vestibular migraine, Meniere's disease and superior semicircular canal dehiscence. •Results from our study in 22 patients with vestibular paroxysmia show patients with multiple short episodes of daily vertiginous spells lasting seconds or minutes (82%) often described by the patien...

NLRP3 inflammasome activation in human vestibular schwannoma: Implications for tumor-induced hearing loss.

Vestibular schwannoma (VS) is the fourth most common intracranial tumor, arising from neoplastic Schwann cells of the vestibular nerve and often causing debilitating sensorineural hearing loss (SNHL) and tinnitus. Previous research suggests that the abnormal upregulation of inflammatory pathways plays a highly significant, though infrequently described role in VS pathobiology, and that VS-associated SNHL is due not only to mechanical compression of the auditory nerve but also to differences in the intrinsic...

Impact of cochlear modiolus dose on hearing preservation following stereotactic radiosurgery for non-vestibular schwannoma neoplasms of the lateral skull base: a cohort study.

Radiation dose to the cochlea has been proposed as a key prognostic factor in hearing preservation following stereotactic radiosurgery (SRS) for vestibular schwannoma (VS). However, understanding of the predictive value of cochlear dose on hearing outcomes following SRS for patients with non-VS tumors of the lateral skull base (LSB) is incomplete. The authors investigated rates of hearing loss following high-dose SRS in patients with LSB non-VS lesions compared with patients with VS.

Vestibular rehabilitation exercises programs to improve the postural control, balance and gait of children with sensorineural hearing loss: A systematic review.

Several studies have demonstrated that children with sensorineural hearing loss (SNHL) exhibit postural instabilities, as well as balance and gait disorders, due to the vestibular dysfunction that they are prone to display as a consequence of inner ear injury. Thus, some experiments have proposed vestibular rehabilitation exercises programs as a treatment to improve these motor skills in children with SNHL.

Increased expression of blood muscarinic receptors in patients with reflex syncope.

Pathophysiology of reflex syncope is not fully understood but a vagal overactivity might be involved in this syncope. Previously, overexpression of muscarinic M2 receptors and acetylcholinesterase was found in particular in the heart and in lymphocytes of rabbits with vagal overactivity as well as in hearts of Sudden Infant Death Syndromes. The aim of this present study was to look at M2 receptor expression in blood of patients with reflex syncope. The second objective was to measure acetylcholinesterase ex...

Gait analysis in patients after bilateral versus unilateral total hip arthroplasty.

Gait abnormalities were reported in patients after total hip arthroplasty (THA). One-stage bilateral THA was introduced for bilateral hip pathologies, showing similar clinical and surgical outcome to unilateral procedure. However, no studies analyze the gait features after bilateral THA surgery compared to unilateral THA.

Psychiatric Considerations in the Management of Dizzy Patients.

Research over the last 4 decades has revealed a great deal of information about psychiatric and functional causes, consequences, and comorbidity of vestibular syndromes. Primary care clinicians, neurologists, and otologists who are willing to set aside the 20th century notion of "psychogenic dizziness" and incorporate 21st century concepts about 5 behavioral entities into their practices will be rewarded for their efforts with a marked improvement in diagnostic acumen and therapeutic effectiveness. Panic at...

Chemical sympathectomy attenuates lipopolysaccharide-induced increase of plasma cytokine levels in rats pretreated by ACTH.

The sympathetic nervous system participates significantly in the regulation of immune functions. In support of this, data indicate that besides vagal afferent and efferent pathway, sympathetic nerves represent crucial component of inflammatory reflex. In addition, it was shown that efferent arm of this reflex might be activated by ACTH. Therefore, we investigated the effect of chemical sympathectomy on lipopolysaccharide (LPS)-induced increases in plasma IL-1β, IL-6, and TNF-α levels in rats. Plasma IL-10...

An unusual case of bilateral anterior opercular syndrome from a neuro-rehabilitation perspective.

Bilateral anterior opercular syndrome, also known as Foix-Chavany-Marie syndrome, is relatively rare and is characterized by inability of voluntary activation of facial, lingual, pharyngeal, and masticatory muscles with preserved automatic and reflex movements such as smiling and yawning. The syndrome is caused by bilateral lesions of the anterior opercula and results in severe impairments with speech and swallowing. This article describes a patient with bilateral anterior opercular syndrome secondary to em...

Exaggerated pressor and sympathetic responses to stimulation of the mesencephalic locomotor region and exercise pressor reflex in type II diabetic rats.

The cardiovascular responses to exercise are potentiated in patients with type 2 diabetes mellitus (T2DM). However, the underlying mechanisms causing this abnormality remain unknown. Central command (CC) and the exercise pressor reflex (EPR) are known to contribute significantly to cardiovascular control during exercise. Thus, these neural signals are viable candidates for the generation of the abnormal circulatory regulation in this disease. We hypothesized that augmentations in CC as well as EPR function ...

Bilateral facial palsy.

Because the incidence of bilateral facial palsy is extremely low, clinical diagnosis and treatment may be delayed and the possibility of misdiagnosis is high. This systematic review, therefore, evaluated the clinical manifestations of bilateral facial palsy. The SCOPUS and PubMed databases were searched through 31 August 2018, using the search term 'bilateral facial palsy'. Reference lists of identified studies were also reviewed. A search of titles and abstracts identified 390 studies; after eliminating ...

Acute Presentation of Vestibular Schwannoma Secondary to Intratumoral Hemorrhage: A Case Report and Literature Review.

Vestibular schwannomas (VS) are common slow-growing tumors that typically present with the insidious progression of unilateral hearing loss, tinnitus, vertigo, and gait imbalance. Clinically significant intratumoral acute hemorrhage is exceedingly rare and can present with the acute onset of symptoms, neurologic deterioration, and significant dysfunction of cranial nerves VII and VIII. We discuss a 40-year-old male who developed mild hearing loss and headaches over the course of a month prior to presenting ...

Deletion of Brg1 causes stereocilia bundle fusion and cuticular plate loss in vestibular hair cells.

Brg1 is an ATPase subunit of the SWI/SNF chromatin-remodeling complex, and it is indispensable for the development and homeostasis of various organs. Conditional deletion of Brg1 in cochlea hair cells (HCs) leads to multiple structural defects and profound deafness. However, the premature death of Brg1-deficient cochlea HCs hindered further study of the role of Brg1. In contrast to cochlea HCs, Brg1-deficient vestibular HCs survived for a long time. Therefore, HC apical structure and vestibular function wer...

Peripheral vestibular plasticity vs central compensation: evidence and questions.

Over the last few decades, several studies have been conducted to identify the mechanisms involved in spontaneous functional recovery following peripheral vestibular damage. Different reactive processes occur at both the central and peripheral levels over the first few hours after the loss of the peripheral vestibular input. The restoration of the electrophysiological homeostasis between opposite vestibular nuclei is one of the key mechanisms of central compensation. This is achieved through a mosaic of bio...

Vestibular neurons with direct projections to the solitary nucleus in the rat.

Anterograde and retrograde tract tracing were combined with neurotransmitter and modulator immunolabeling to identify the chemical anatomy of vestibular nuclear neurons with direct projections to the solitary nucleus in rats. Direct, sparsely branched but highly varicose axonal projections from neurons in the caudal vestibular nuclei to the solitary nucleus were observed. The vestibular neurons giving rise to these projections were predominantly located in ipsilateral medial vestibular nucleus. The cell bod...
