Sinusitis is a very common disease and exists in both an acute and a chronic form. In Europe, over nine per cent of the population suffers from chronic sinusitis.
The author of the thesis is Pernilla Sahlstrand Johnson, a PhD student and ear, nose and throat doctor at Lund University and Skåne University Hospital. In the work on the thesis, she and her colleagues at the Faculty of Engineering at Lund University tested and evaluated a new method to better diagnose sinusitis.
The method employs a Doppler ultrasound sensor, which, unlike a normal ultrasound or CT scan, can determine the viscosity of the sinus fluid. Until now, the only way to find this out for certain has been by flushing out the maxillary sinuses, which is an unpleasant procedure for the patient.
Only patients with thick sinus fluid are considered to need antibiotics, while for those with thin fluid there are other effective treatment options.
“Antibiotic resistance is seen as a growing problem. One in four people in Sweden takes antibiotics at least once a year, and many of these have been diagnosed with sinusitis. A more accurate diagnosis could reduce the amount of antibiotics prescribed and the right treatment could also reduce costs”, says Pernilla Sahlstrand Johnson. “We have used the new method in the laboratory with good results. We are planning to trial the Doppler ultrasound sensor in a clinical environment soon, on a number of patients at the Ear, Nose and Throat Clinic at Skåne University Hospital in Malmö and Lund.”
Pernilla Sahlstrand Johnson has also studied the self-perceived quality of life of a group of just over 200 patients awaiting sinus surgery. As well as the Ear, Nose and Throat Clinics in Skåne, patients at Karolinska and Sahlgrenska University Hospitals have also completed questionnaires for the study, which is one of the largest of its kind.
Both general questionnaires and questionnaires specific to sinusitis have been used, and the answers shed light on the patients’ perceived quality of life and mental health and their absence from work. The responses indicate high levels of absence – patients reported 8–14 days of sick leave in the course of a year resulting from their sinus problems.
“The participants in our study experienced a significant fall in quality of life as a result of their sinusitis – greater than in other large patient groups with diseases such as angina or cancer. Sinusitis probably also has a major financial impact on society, as it is a common disease and leads to relatively high levels of sick leave”, says Pernilla Sahlstrand Johnson.
Pernilla Sahlstrand Johnson defended her thesis on 30 September 2011. The title of the thesis is "On health-related quality of life and diagnostic improvement in rhinosinusitis"

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
