A new study published in The New England Journal of Medicine found that a shortened five-day antimicrobial treatment regimen for middle ear infections in young children is less effective than the standard 10-day regimen. The study also failed to show a significant reduction in antibiotic resistance threat.
Researchers found a rare genetic variant in the A2ML1 gene associated with an increased risk of middle ear infections. The study, led by Dr. Regie Santos-Cortez, identified the variant in 37 Filipinos and two European-Americans with otitis media, suggesting it may be the result of a founder effect from Spain.
Researchers found that a flu virus can inflame nasal tissue and increase bacterial growth, leading to middle ear infections. The study suggests that the flu virus modifies the immune system's response to certain bacteria, enabling them to infect the middle ear.
A systematic review of 40 studies found that ear tube surgery has no significant impact on hearing, speech, or other functional outcomes beyond a short period. Adenoidectomy also showed limited benefits in reducing time with ear infections and improving hearing up to two years.
Researchers at Clemson University identified two regions in the chicken genome associated with congenital deafness and spine deformities in humans. The Araucana breed's unique ear tufts and rumplessness provide a model for studying human genetic mutations.
A recent study led by Loyola University Medical Center physician Matthew Kircher identified a simple way to reduce healthcare costs without compromising care. The researchers found that in 178 cases, there was virtually perfect agreement between otologists' findings and official diagnoses from the pathology lab, suggesting that these e...
Scientists at King's College London found that the middle ear cavity is formed by two different tissue types, one of which is less efficient at clearing debris and more susceptible to infection. This 'evolutionary glitch' may be the reason why some children are more prone to developing chronic ear problems like glue ear.
A new biodegradable antibiotic pellet can be implanted in the middle ear to target glue ear infections, potentially reducing the need for repeated grommet operations. The pellet slowly releases antibiotics over three weeks, addressing biofilms that cause up to 20% of cases.
A new treatment for sudden hearing loss has been found comparable to oral steroids, providing patients with more treatment options. The study showed that both treatments led to similar hearing improvements, but patients with severe hearing loss benefited more from oral steroids.
A large clinical trial has shown that direct injection of steroids into the middle ear is equally effective as oral steroids in restoring hearing levels in patients with sudden deafness. The study results, published in the Journal of the American Medical Association, have implications for treatment options and cost-effectiveness.
A recent clinical trial found that nasal steroid sprays do not significantly improve symptoms of eustachian tube dysfunction. The study enrolled patients with either otitis media with effusion or negative middle ear pressure and randomly assigned them to receive either a steroid spray or a placebo.
Children with chronic otitis media with effusion (COME) experience changes in their sense of taste, which may be related to childhood obesity. Researchers found that the taste thresholds of sweet and salty tastes were elevated for children in the COME group.
