UK researcher identifies brain region responsible for spatial hearing
A major science prize was today awarded to a researcher who is looking for the region of the brain that helps us to hear someone in a noisy place, such as a party or bar, and is responsible for "training" the brain to hear better in these situations.

Boosting local immunity in nose can help treat chronic sinusitis
Researchers at Johns Hopkins have evidence that curbed activity from several key chemicals on the inner lining of the nose are linked to chronic sinusitis that fails to respond to the usual current treatments.

Acidic mammalian chitinase gene linked to recurrent sinusitis
Although it's unclear why it's so, scientists at Johns Hopkins have linked a gene that allows for the chemical breakdown of the tough, protective casing that houses insects and worms to the severe congestion and polyp formation typical of chronic sinusitis.

Beta-actin mutations linked to deafness and dystonia
Findings of a recent genetic study on developmental brain disorders may be the "tip of an iceberg" revealing factors involved with a number of congenital diseases, according to UC Irvine researchers. The study is the first to find that mutations in the structural proteins in brain cells - beta-actin - are linked to disorders such as deafness and dystonia, a debilitating neural disease, and further suggests that genetic variants of these proteins may play a wider role with inherited human diseases. Study results appeared in the June issue of the American Journal of Human Genetics.

Role of Folic Acid in Treatment of Laryngeal Leucoplakia
Folic acid supplements may prevent cancer progression and promote regression of disease, according to a new study. Published in the July 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the small study found that 31 of 43 patients with the precancerous laryngeal lesion called leucoplakia demonstrated 50 percent or greater reduction in the lesion size after six months of taking folate supplements. In 12 of 31 responders, there was no evidence of the original lesion. Folate levels in the patients' blood also increased significantly from baseline while homocysteine levels decreased significantly. This study provides data to support the hypothesis that folate insufficiency is a risk factor for cancer progression.

Hyperactivity, attention deficit, sleepiness, and ADHD often improves after tonsillectomy - Study
In fact, about half of the children in the study who were found to have Attention-Deficit/Hyperactivity Disorder before tonsil surgery no longer met criteria for this diagnosis one year later. Other cognitive and behavioral issues also improved.

New vaccine against ear infection
Czech scientists have developed a vaccine to help prevent ear infections in young children. Next to the common cold, ear infections are the most commonly diagnosed childhood illness. More than three out of four children in the US have at least one ear infection by the time they reach three years of age. The infection known as acute otitis media could be very painful and - very rarely - cause long term damage. Roman Prymula, from the University of Defence at Hradec Kralove, Czech Republic, administered almost 5,000 infants with either the ear vaccine or a hepatitis A vaccine at various ages between three and 15 months.

Middle cranial fossa approach preserves hearing in acoustic neuroma patients
Even when they're extremely small, tumors on the nerves that connect the brain to the ear can wreak havoc on a person's hearing and balance. But removing them is a delicate process that can, in some cases, cause further harm.

Aldosterone linked to good hearing as we age
Researchers have linked a hormone known to adjust levels of key brain chemicals to the quality of our hearing as we age. The more of the hormone that older people have in their bloodstream, the better their hearing is, and the less of the hormone, the worse their hearing is.

Salicylate causes tympanic membranes to rupture more easily
It's well known that high doses of aspirin can cause ulcers and temporary deafness, but the biochemical mechanism responsible for these phenomena has never been deciphered. New research from Rice University offers clues, showing for the first time how salicylate -- an active metabolite of aspirin -- weakens lipid membranes. Researchers believe these mechanical changes disrupt the lining of the stomach, which functions to protect underlying tissue from the acidic contents of the gut. By a similar mechanism, the changes may result in aspirin-related deafness by interfering with the proper function of prestin, a transmembrane protein that's critical for mammalian hearing.

Amount of hearing in an ear prior to surgery is unrelated to a patient's ability to interpret speech using an implant
Hearing-impaired individuals with severe to profound hearing loss and poor speech understanding who possess some residual hearing in one ear may experience significant communication benefit from a cochlear implant even if it is placed in the worse-hearing ear, a Johns Hopkins study suggests.

How sensory hair cells in the ear develop unique shapes that enable sound perception
Scientists are one step closer to understanding the genetic pathway involved in the development of hearing. New research findings, published online this week in the journal Nature Genetics, detail how sensory hair cells in the ear �� the cells largely responsible for hearing �� develop unique shapes that enable the perception of sound.

Chronic sinus infection is not a tissue issue
Mayo Clinic researchers have found that the cause of chronic sinus infections lies in the nasal mucus -- the snot -- not in the nasal and sinus tissue targeted by standard treatment.

Extracorporeal septoplasty for difficult nasal reconstructive surgery
A surgical technique that requires the removal, restructure and re-implantation of the nasal septum (the partition of the nose between the nostrils) appears to be a useful option for repairing the hard-to-treat severely deviated septum, according to an article in the July/August issue of the Archives of Facial Plastic Surgery, one of the JAMA/Archives journals.

Cidofovir as an Useful Adjunct in Treating Recurrent Respiratory Papillomatosis
Recurrent Respiratory Papillomatosis (RRP) is a chronic disease evidenced by wart-like lesions in the larynx, particularly on the vocal folds. Debulking or removing a major part of the lesions is generally the treatment of choice in order to preserve as much laryngeal function as possible and limit the morbidity associated with surgical treatment of this generally benign disorder.
