Infants and children who suffer from congenital or acquired hearing loss can face a lifetime of speech and language deficits, poor academic performance and emotional problems. In the clinical report, "Hearing Assessment in Infants and Children: Recommendations Beyond Neonatal Screening, " researchers have developed an algorithm to assist pediatricians determine the course of treatment when a hearing screening indicates hearing loss in children from infants to 18 years of age. Confirmed abnormal hearing test results require ongoing evaluation and intervention by a team of specialists including an audiologist, otolaryngologist, speech-language pathologists and teachers.
It's a ringing, a buzzing, a hissing or a clicking - and the patient is the only one who can hear it. Complicating matters, physicians can rarely pinpoint the source of tinnitus, a chronic ringing of the head or ears that can be as quiet as a whisper or as loud as a jackhammer. Now a Henry Ford Hospital study finds that a non-invasive imaging technique can actually aid in the diagnosis of tinnitus and may detect a reduction in symptoms after different treatments, offering hope to the more than 50 million patients with tinnitus. "Until now, we had no way of pinpointing the specific location of tinnitus in the brain, " says study co-author Michael D.
A comprehensive study of the prevalence and risk factors for noise-induced hearing loss (NIHL) show that men, especially those who are white and married, are significantly more at risk than women, according to new research presented at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in San Diego, CA. The study, which analyzed the audiometric testing data from 5, 290 people between the ages of 20 and 69 years indicates that more than 13 percent of subjects suffer from NIHL, which would correspond with approximately 24 million Americans suffering from the ailment. The strongest association was of gender, where men are 2.
Increased intakes of antioxidant vitamins have no bearing on whether or not a man will develop hearing loss, but higher folate intake can decrease his risk by 20 percent, according to new research presented at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in San Diego, CA. The study, which identified 3, 559 cases of men with hearing loss, found that there was no beneficial association with increased intakes of antioxidant vitamins such as C, E, and beta carotene. However, the authors found that men over the age of 60 who have a high intake of foods and supplement high in folates have a 20 percent decrease in risk of developing hearing loss.
Drivers who frequently take to the road with the top down may be risking serious damage to their hearing, according to research presented at the 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting & OTO EXPO, in San Diego, CA. A prospective study of the convertible-driving experience measured noise levels at speeds of 50, 60, and 70 miles per hour (mph), and indicated that drivers are consistently exposed to between 88 and 90 DbA, with a high of 99 Db. Long or repeated exposure to sounds over 85 Db is widely recognized to cause permanent hearing loss. Road surface, traffic congestion, wind noise, and driving speed were all contributing factors.
The vast majority of school-aged children can focus on the voice of a teacher amid the cacophony of the typical classroom thanks to a brain that automatically focuses on relevant, predictable and repeating auditory information, according to new research from Northwestern University. But for children with developmental dyslexia, the teacher's voice may get lost in the background noise of banging lockers, whispering children, playground screams and scraping chairs, the researchers say. Their study appears in the Nov. 12 issue of Neuron. Recent scientific studies suggest that children with developmental dyslexia - a neurological disorder affecting reading and spelling skills in 5 to 10 percent of school aged children - have difficulties separating relevant auditory information from competing noise.
