A bodyguard for your ears: Scientists discover novel pain sensors in inner ear that warn of dangerously loud noise

Our hearing has a secret bodyguard, a newly discovered connection from the cochlea to the brain that warns of intense incoming noise that causes tissue damage and hearing loss. Scientists believe it's the ear's novel pain system designed to protect it from dangerous noise. Because the ear doesn't have the nerve cells that normally detect pain, it needs its own alert system. The findings could usher new treatments for painful hearing conditions like tinnitus and hyperacusis.

CONCLUSIONS: IHS is a rare entity with a difficult diagnosis. It requires high quality neuroimaging tests for its detection and early treatment. The evaluation of both techniques, MRI and Radionuclide cisternography, allow to specifically determinate the level of CSF leakage. EBP-guided imaging, according to clinical practice, provides a better chance of therapeutic success compared to a blind performance.

This article reports a case of exploding head syndrome (EHS) as an aura of migraine with brainstem aura (MBA). A middle-aged man presented with intermittent episodes of a brief sensation of explosion in the head, visual flashing, vertigo, hearing loss, tinnitus, confusion, ataxia, dysarthria, and bilateral visual impairment followed by migraine headache. The condition was diagnosed as MBA. Explosive head sensation, sensory phenomena, and headaches improved over time with nortriptyline. This case shows that EHS can present as a primary aura symptom in patients with MBA. PMID: 29694468 [PubMed - in process]

This study describes characteristics of FMD patients with and without A and/or D (A/D).Methods: Patients enrolled in the US Registry for FMD between 2009-2017 and had A/D information were analyzed (n=985). Diagnosis of A/D was ascertained from patient charts or self-reported via medical history questionnaires at time of registry enrollment. Demographics, family history, past medical history, presenting symptoms, and affected vascular beds were compared between patients with and without A/D.Results: A total of 351 (35.6%) had A/D. Of patients with A/D, 126 (35.9%) had both. Patients with A/D were more likely to have a famil...

Progress in drug development has brought a host of novel agents for the treatment of neurological disorders ranging from multiple sclerosis to chronic pain. However, the treatment of most neurological disorders is still dependent on older medications. This includes medications, such as carbamazepine, with clinical activity across a broad number of disorders. Carbamazepine was first approved in 1963 for the treatment of epilepsy but has been used for treating types of schizophrenia, bipolar disorder, neuropathic pain, tinnitus, and trigeminal neuralgia. Although this agent is safe and effective for many patients, there is a...

Abstract BACKGROUND Tocainide is an antiarrhythmic agent belonging to class IB that was primarily used for suppression of symptomatic ventricular arrhythmias. Tocainide was also reported to relieve pain such as tic douloureux, trigemina neuralgia in humans and tinnitus. Significant antinociception, as assayed on the hot-plate test, was observed after intraperitoneal injection of tocainide, too. By the mid-1980s tocainide was emerging as a more consistently effective treatment for myotonic disorders. Numerous reports of serious adverse reactions led to the use of tocainide being discontinued, even though research o...
