2. 11. Studies on the influence of sensory stimulation (acupuncture) on neuropeptide release in the saliva

   Author : Irena Dawidson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : acupuncture; substance P; neurokinin A; calcitonin gene-related peptide; vasoactive intestinal polypeptide; neuropeptide Y; xerostomia; salivary secretion rates;

   Abstract : The aim of this thesis was to elucidate the mechanisms behind the effect of sensory stimulation (acupuncture) on the salivary flow rates of xerostomic patients. We hypothesised that the sensory stimulation activates the sensory and autonomic nervous systems, leading to an increased release of neuropeptides that influence salivary secretion in co-operation with or/and beside the classical neurotransmitters.

4. 12. Radiation-induced dysphagia in head and neck cancer - risk structures and methodological aspects

   Author : Johanna Hedström; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; head and neck cancer; radiation therapy; dysphagia; patient-reported outcomes; quality of care;

   Abstract : Background/Aims: Swallowing difficulties are common after radiation therapy (RT) in head and neck cancer (HNC). The overall aim of this thesis was to address radiation-induced late dysphagia with regard to investigating anatomical risk structures related to the development of radiation-induced dysphagia, as well as methodological aspects in the evaluation of swallowing.

5. 13. Studies of different clinical manifestations of Sarcoidosis and the role of genetic factors

   Author : Pernilla Darlington; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Sarcoidosis is a systemic disease of unknown etiology characterized by the formation of non-necrotizing granulomas in the affected organs. Engagement of the lungs and/or thoracic lymph nodes (LN) are found in more than 90 % of all cases, but almost any organ such as the eyes, skin, heart and nervous system can be involved. READ MORE

6. 14. Verification of Dose Calculation Algorithms in Treatment Planning Systems for External Radiation Therapy: A Monte Carlo Approach

   Author : Elinore Wieslander; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; tomografi; medicinsk instrumentering; radiotherapy; dose calculation algorithm; verification; Monte Carlo calculation; electron beam; photon beam; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; treatment planning system;

   Abstract : This thesis presents a new verification concept, the virtual accelerator, for dose calculation algorithms used in treatment planning systems (TPSs) for external beam radiotherapy. The algorithm input data required to implement a treatment unit in the TPS are generated by Monte Carlo simulations as are the beam reference data needed for the subsequent evaluation of the dose calculation algorithm.

7. 15. Mobile phone use and risk of intracranial tumors

   Author : Stefan Lönn; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Acoustic neuroma; brain tumor; case-control study; epidemiology; intracranial tumor; mobile phone; radiofrequency radiation;

   Abstract : Mobile phones are today an integral part of many people's lives in western societies. The phones emit radiofrequency radiation when being used. Concerns have been raised about possible effects that the exposure may have on the health of the mobile phone user. READ MORE
