Introduction: The electrohydraulic lithotripter has revolutiomised the treatment of urolithiasis. It produces shock waves by electrical discharge in water associated at a noise. We know that the hearing damage is above 85 decibels. Our goal is determine if the Econolith 2000 lithotriptor produce hearing damage.
Patients And Methods: 10 patients were treated. They had audiometry prior to a single exposure to lithotripsy and twenty four hours after treatment. All our patients wore protective ear. The intensity of the sound was measured.
Results: Inside of the operated room the intensity of the sound was 96 decibels, outside was 70. There weren't hearing damage in the patients.
Conclusions: The lithotriptor Econolith 2000 doesn't produce hearing damage in patients with protective ear.

Noise-induced ribbon synapse loss in the mouse basal cochlear region does not reduce inner hair cell exocytosis.

Noise-induced hearing loss is one of the most common forms of hearing loss in adults and also one of the most common occupational diseases. Extensive previous work has shown that the highly sensitive synapses of the inner hair cells (IHCs) may be the first target for irreparable damage and permanent loss in the noise-exposed cochlea, more precisely in the cochlear base. However, how such synaptic loss affects the synaptic physiology of the IHCs in this particularly vulnerable part of the cochlea has not yet been investigated.

Mitochondrial DNA (mtDNA) variants considerably affect diabetes mellitus by disturbing mitochondrial function, energy metabolism, oxidative stress response, and even insulin secretion. The m.3243 A > G variants is associated with maternally inherited diabetes and deafness (MIDD), where early onset diabetes and hearing loss are prominent features.

Objectives: An occupational disease (OD) is a disorder or health condition which arises due to work related activities and tasks or is caused by work environment. The impact of ODs on medical and social system may be considered as a very important in relation to mortality, morbidity, and invalidity. The most common ODs in the European Union are musculoskeletal disorders (58% of all ODs in 2015).

It remains unclear however whether or not noise exposure also compromises the cochlear efferent system, a feedback pathway in the brain that fine-tunes hearing sensitivity in the cochlea. We examined the effects of noise-induced hearing loss on the spontaneous action potential (AP) firing pattern in mouse lateral olivocochlear (LOC) neurons.

Hair cell (HC) loss, frequently induced by ototoxic agents such as gentamicin, leads to irreversible hearing loss. Because of the restricted regenerative capabilities of the mammalian inner ear, the exploration of therapeutic strategies to restore damaged HCs is critically needed. Recombinant human Neuritin (rhNeuritin), a neurotrophic factor with established roles in promoting cell survival and regeneration across various systems, presents itself as a promising therapeutic candidate for HC repair.
