Hearing Loss – Researchers study method to regenerate Inner Ear Damage

Hearing Loss – Researchers study method to regenerate Inner Ear Damage

Ear

Researchers from Massachusetts General Hospital continue studies on hearing loss and found that gene knockout affects different areas of the inner ear.  The researcher’s goal is to be able to regenerate the inner ear’s hair cells that are responsible for converting sound into nerve impulses that is then transmitted to the brain.

The current research study is being reported in the upcoming issue of Proceeding of the National Academy of Sciences and will also be published online as well.  The researchers focused on the suppression of retinoblastoma (Rb) protein.  They discovered that changing the protein had different effects in the inner ear.

"In these first studies of the role of the Rb protein in the ears of postnatal mice, we have confirmed that – under the right conditions – mature hair cells can go through the cell cycle and produce new, functioning hair cells. But we've also confirmed that you need to block Rb reversibly and at an early stage of development, otherwise the hair cells will die," said Zheng-Yi Chen, DPhil, of the MGH Neurology Service who is the study's senior author.  Hearing Loss – Researchers study method to regenerate Inner Ear Damage


Antibiotics and Hearing Loss – Researchers found Aspirin can help in preventing Hearing Loss when taking Aminoglycosides

The antibiotic called aminoglycosides are an inexpensive treatment for acute infections such as tuberculosis and for treatment of cystic fibrosis patients as well as other conditions.  This type of antibiotic has been used for over 60 years, but one of the side effects of taking this medication is irreversible hearing loss.

Researchers from the University of Michigan’s Kresge Hearing Research Institute along with Chinese colleagues studied how hearing could be preserved while taking the antibiotic by taking aspirin with the medication.  The complete study has been published in the April 27th, issue of the New England Journal of Medicine.

Asthma – Dirty House is better than a clean one for preventing Asthma in Children

Asthma – Dirty House is better than a clean one for preventing Asthma in Children

Girl with Asthma Inhaler

A study published in the April 18th, online Journal of Allergy and Clinical Immunology showed that children that were exposed to more dust and microbials had less of a chance of developing asthma.

Researchers from Utrecht University in the Netherlands and Massey University in Wellington, New Zealand measured how much children were exposed to microbials when they were 3 months old and followed up and measured again at 4 years old.

The children were watched for the development of asthma symptoms such as wheezing or atopic sensitization.  Atopic sensitization can develop into allergies and may be inherited from one of their parents; if a child develops this allergy the reaction is instant when coming into contact with the allergen.

Weight Loss Ear Staple – Mississippi Medical Board shuts down Businesses offering Ear Stapling for Losing Weight

Weight Loss Ear Staple – Mississippi Medical Board shuts down Businesses offering Ear Stapling for Losing Weight

Ear Stapling Equipment

The state medical board of Mississippi ordered 14 weight loss businesses that do ear stapling because they say they are doing so illegally.

According to a news report by ABC news, Mal Morgan who is the executive director of the Mississippi Board of Medical Licensure had received several complaints of people that had the ear stapling performed causing serious ear infections.  Doctor’s in the state had more people coming in to get the staple removed and to treat the infection.

The ear stapling business advertised this as a weight loss procedure which is why they closed down the businesses as they are practicing medicine without a license.  Weight Loss Ear Staple – Mississippi Medical Board shuts down Businesses offering Ear Stapling for Losing Weight


Sleep Apnea and Allergies – Children that Snore often have Parents that Snore

Sleep Apnea and Allergies – Children that Snore often have Parents that Snore

Sleeping Baby

Children are at a three times higher risk for snoring if one of their parents snores.  Researchers from the Cincinnati Children’s Hospital Medical Center also found that children that test positive for allergies are two times more often snore while sleeping.  The study was first published in the April issue of the journal called CHEST. 

"We found that snoring was associated with presence of allergic sensitization (a condition called atopy)," according to Maninder Kalra, M.D., a physician and researcher in pulmonary medicine at Cincinnati Children's and who is also a corresponding author of this study.  Sleep Apnea and Allergies – Children that Snore often have Parents that Snore


New Balloon Sinuplasty Cures Sinusitis by Enlarging the Sinuses – Some Dangers But Procedure is Done in United States Now

New Balloon Sinuplasty Cures Sinusitis by Enlarging the Sinuses – Some Dangers But Procedure is Done in United States Now

Balloon

Simple outpatient surgery may help improve symptoms of sinusitis in people with abnormal bone growth in the sinus cavity.  The treatment has only been available in the US since December, but it appears to work.  After the surgery the patients’ sinus openings become significantly wider, allowing sufferers to breathe normally through their noses.

The procedure, called balloon sinuplasty, requires general anesthesia. The doctors thread a guide wire catheter equipped with a tiny balloon into the nostrils and up to the blockage.  They then inflate the balloon about a quarter inch.  This is just enough to open the passageway.  The balloon is then deflated and withdrawn.

Ear nose and throat (ENT) surgeons are being trained in the procedure.  Newsdial.com reports that the procedure does have some risks.  According to Dr. Christopher Brown, a principal researcher at the Alfred Hospital in Melbourne Australia, “Because the brain is in close proximity to the sinuses, there is potentially a risk of injury.  The frontal sinus in particular can be challenging to many ENT surgeons and so any new developments are always welcomed.”  New Balloon Sinuplasty Cures Sinusitis by Enlarging the Sinuses – Some Dangers But Procedure is Done in United States Now


New PillCam Used to Examine Esophagus - Takes Colored Images After Swallowed - Pictures Inspected for Ulcers or Signs of Cancer

New PillCam Used to Examine Esophagus - Takes Colored Images After Swallowed - Pictures Inspected for Ulcers or Signs of Cancer

Pill Cam

A new device called the Pillcam is being used for patients concerned with Gastroesophageal Reflux Disease or GERD.  The device is about the size of a multivitamin so it is easy to swallow, and has cameras at both ends of the pill.  During the procedure, there are three sensor arrays placed on the patient’s chest that send data back to a data recorder worn on a belt around the waist. 

Doctor Tim Johnson, ABC News' medical editor, wanted to make sure his chronic heartburn wasn’t causing serious damage to his esophagus.  He underwent the procedure which requires the patient to swallow the pill lying down and then sit up straight over a five minute period.  The gradual inclination ensures that the pill travels slowly down the esophagus.  The patient remains in the upright position for an additional 15 minutes to ensure the pill travels to the stomach.  The disposable pill is later excreted naturally.

Early Antibiotic Use May be Linked to Asthma - Ear Infections Bronchitis and Upper Respiratory Infection Treatments May Lead to Childhood Asthma

Early Antibiotic Use May be Linked to Asthma - Ear Infections Bronchitis and Upper Respiratory Infection Treatments May Lead to Childhood Asthma

Asthma Patient X-ray

Researchers warn that antibiotic use may double the risk of childhood asthma.  According to a study by the University of British Columbia, “children under age 1 who are treated with an antibiotic are twice as likely to develop asthma in childhood.”

Current guidelines recommend antibiotics for children under the age of 2 who contract ear infections.  The study’s coauthor, Fawziah Marra, M.D, said “In children, antibiotics are commonly used to treat ear infections, upper respiratory tract infections, and bronchitis, but not every childhood infection requires an antibiotic.” Since most upper respiratory tract infections and bronchitis are viral, antibiotics are ineffective.  Early Antibiotic Use May be Linked to Asthma - Ear Infections Bronchitis and Upper Respiratory Infection Treatments May Lead to Childhood Asthma


Rheumatoid Arthritis and Hearing Loss may be Unrelated

Rheumatoid Arthritis and Hearing Loss may be Unrelated

Ear

The Mayo Clinic completed a study recently that found that people with Rheumatoid arthritis do not have an increased risk of hearing loss compared to the general population.  This contrasts previous research that found a link between rheumatoid arthritis and hearing problems.  This research report will be presented today at the American Auditory Society annual meeting in Scottsdale, Arizona.

"This is very good news for rheumatoid arthritis patients," said Eric Matteson, M.D., Mayo Clinic rheumatologist and the senior study researcher. "Patients with rheumatoid arthritis actually have preserved hearing and are no more susceptible to hearing loss than those who do not have the disease; there is no measurable difference with standard testing. This was surprising. I expected to see more hearing loss in rheumatoid arthritis patients."  Rheumatoid Arthritis and Hearing Loss may be Unrelated

Finally an Ear Infection Vaccine -  GlaxoSmithKline develops Vaccination in Effort to Prevent Middle Ear Infections

Middle Ear

Researchers from GlaxoSmithKline have developed a vaccine that may help prevent ear infections in children under the age of 2.  It is hoped the vaccine will successfully prevent one of the most commonly diagnosed childhood ear infections, the Acute otitis media (middle ear infection) caused by the bacteria Streptococcus pneumoniae and Haemophilus influenzae.

The drug was tested by researchers in the Czech Republic.  A vaccine containing 11 different strains of pneumoniae attached to a protein derived from H. influenzae was tested on more than 4,000 infants.  They set up control groups between the ages of 3 and 15 months.  Finally an Ear Infection Vaccine -  GlaxoSmithKline develops Vaccination in Effort to Prevent Middle Ear Infections


Link between Hearing Loss and lower Levels of Aldosterone Hormone

Link between Hearing Loss and lower Levels of Aldosterone Hormone
