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.
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."
The thesis has been successfully defended.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
