Bacterial spray can help children with glue ear

29.03.2010
Many children have long-term problems with fluid in the middle ear, and sometimes surgery is the only way to shift it. However, a bacterial nasal spray can have the same effect in some children, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

The study covered 60 children with glue ear, or secretory otitis media (SOM), who were split into three groups. The first group received a solution containing Streptococcus bacteria, the second a solution with Lactobacillus bacteria, and the third a bacteria-free solution (placebo). These solutions were then sprayed into the children's noses for ten days.

"In the group given the Streptococcus spray, a third of the children got much better or were cured completely, while only one child given the bacteria-free spray recovered," says Susann Skovbjerg, a doctoral student at the Department of Infectious Diseases and Clinical Bacteriology. "Treatment with Lactobacillus bacteria was less effective."

A number of different types of bacteria come under the Streptococcus umbrella. The type used in the study is normally found in the mouth and belongs to the viridans group. The researchers have various theories as to why a spray with these bacteria can help children with glue ear.

"One explanation for the marked improvement may be that the spray stimulates the immune system to conquer the long-term inflammation," says Skovbjerg.

Studies of bacterial sprays have been performed before, including in patients who have had a throat infection and children suffering from recurring acute ear infections, and now their effect has been studied in children with glue ear. The results of these studies have generally been good, but Skovbjerg says that more studies are needed to confirm the results and look at what actually happens in the children treated with the spray.

"In the longer term, bacterial sprays may come to be part of the treatment for glue ear," she says. "They could be used to help the body to heal itself and so perhaps enable some children to avoid an operation."

GLUE EAR
Glue ear, or secretory otitis media (SOM), can occur after an acute ear infection or a cold. It is common in children and can spell long-term problems with fluid in the middle ear, which can result in impaired hearing and, in rare cases, permanent damage to the eardrum. The children are normally examined by an ear specialist, and the condition normally resolves itself. If the fluid does not disappear spontaneously, an operation is performed to insert a plastic tube through the eardrum.
Around 10,000 children in Sweden undergo this operation each year.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
