A multicenter study was set up to elucidate the environmental and medical risk factors contributing age-related hearing impairment (ARHI). Nine subsamples, collected by nine audiological centers across Europe, added a total of 4,083 subjects between 53 67 years. Audiometric data (pure-tone average [PTA]) were participants filled out questionnaire on history. People with history disease that could affect excluded. PTAs adjusted for age sex tested association exposure factors. Noise associated...

Can SARS-CoV-2 hitchhike on the olfactory projection and take a direct short route from nose into brain? We reasoned that neurotropic or neuroinvasive capacity of virus, if it exists, should be most easily detectable in individuals who died an acute phase infection. Here, we applied postmortem bedside surgical procedure for rapid procurement tissue, blood, cerebrospinal fluid samples deceased COVID-19 patients infected with Delta, Omicron BA.1, BA.2 variants. Confocal imaging sections...

Age-related hearing impairment (ARHI) is the most prevalent sensory in elderly. ARHI a complex disease caused by an interaction between environmental and genetic factors. The contribution of various factors has been relatively extensively studied. In contrast, investigations to identify risk have only recently initiated. this paper we describe results association study performed on 2418 samples derived from nine centers seven European countries. 70 candidate genes, total 768 tag single...

Age-related hearing impairment (ARHI) is the most common sensory among elderly. It a complex disorder influenced by genetic as well environmental factors. SNPs in candidate susceptibility gene, KCNQ4, were examined two independent Caucasian populations. Two quantitative trait locus (QTL) values investigated: Zhigh and Zlow, measure of high respectively low frequency loss. In first population, statistical analysis 23 genotyped spread across KCNQ4 resulted significant p-values for Zhigh-SNP9...

Image-guided and robot-assisted surgeries have found their applications in skullbase surgery. Technological improvements terms of accuracy also opened new opportunities for robotically-assisted cochlear implantation surgery (RACIS). The HEARO® robotic system is an otological next-generation surgical robot to assist the surgeon. It first provides software-defined spatial boundaries orientation reference information anatomical structures during neurosurgical procedures. Second, it executes a...

Mal de Debarquement Syndrome (MdDS) is a neurological condition typically characterized by sensation of motion, that persists longer than month following exposure to passive motion (e.g., cruise, flight, etc.). The most common form MdDS triggered (MT). However, recently it has been acknowledged some patients develop typical symptoms without an apparent trigger. These cases are identified here as spontaneous or other onset (SO) MdDS. This study aimed address similarities and differences...
