Oral mucositis is an inflammation that affects the mucosa in the mouth. It often affects patients undergoing chemotherapy for cancer. The risk of inflammation can be reduced by cooling the mouth. In this project, ten different mouthpieces for cryotherapy of the oral cavity with air as cooling medium have been modeled in the SolidWorks. Flow simulations have been made on the different mouthpieces to investigate how the air is distributed in the models. The goal of the simulations is that the outflow of air should not differ more than 10 % between the largest and the smallest flow. With the results, the mouthpieces could be fine-tuned. Flow simulation on the ten prototypes gave varying results, some have a good distribution of air between the holes. Some, however, do not evenly spread the air and it flows much less air through certain holes. Three prototypes were printed in hard plastic at an early stage to see how they fit the mouth. At the end of the project, a total of seven models were printed by TADA medical's partner in a softer plastic. Several models then showed some points that need to be considered when designing nozzles. A handful of the models have been tested with the cooling device and the flow has been examined with a heating camera. The other prototypes have not been 3D-printed, so there is nothing about their convenience. To get better results, more advanced simulation requires the environment of the oral cavity with the exact dimensions.

<p>A randomized intervention study, with the aim to compare the effects of individual psychosocial support provided by (1) oncology nurses specially trained in psychological techniques (INS), or (2) psychologists (IPS), to (3) standard care (SC). Breast cancer patients, living in Uppsala County, and about to start adjuvant treatment at the Department of Oncology, Uppsala, were consecutively included between 1998 and 2000. The patients were assessed seven times during two years by self-administered questionnaires. Study I revealed positive effects of both INS and IPS as compared to SC on global quality of life, side effects, and post-traumatic distress. A lower proportion of patients in the intervention groups had psychosocial support provided in routine care compared with the SC group. In study II the patients reported being highly satisfied with the intervention, irrespective of profession providing the support. However, patients in the INS group reported higher levels of benefit regarding disease-related problems than those in the IPS group. In study III total Health Care costs were lower in the intervention groups and since a gain in quality-adjusted life years (QALY) was seen (mean .1 QALY), the interventions dominated. The costs for the interventions were 44 291- 48 978 SEK. In study IV, daily reporting of anxiety, depression and activity on Visual Analogue Scales (VAS) were completed during two weeks before and after the Hospital Anxiety and Depression Scale (HADS) assessments. A point assessment with the HADS captured the situation better than four weeks assessment on three VAS in the diary. The HADS was considered preferable to the diary. The conclusion is that psychosocial support is beneficial for breast cancer patients and that the intervention delivered by nurses was as effective as that given by psychologists. The costs for the interventions were limited.</p>
