2. 11. Preservation of parathyroid function in thyroid and parathyroid surgery

   Author : Stefan Ander; Göran Åkerström; Linköpings universitet; []
   Keywords : Human parathyroid glands; vascular supply; parathyroid preservation; laser Doppler flowmetry; iPTH; autotransplantation; xenotransplantation; a thymic mice; angiogenesis; immunohistochemistry; electron microscopy; ultrastructure; autoradiography; MEDICINE; MEDICIN;

   Abstract : Preservation of normal parathyroid function and calcium homeostasis after operations on the thyroid and parathyroid glands is a difficult assignment in endocrine surgery, and it is crucial to minimise the risks of permanent postoperative hypoparathyroidism. The aim of this thesis was to study the vascular supply of the parathyroid glands and the revascularisation, growth, and function of transplanted parathyroid tissue, in order to add new information about parathyroid preservation.

4. 12. Splanchnic perfusion in cardiac surgery

   Author : Anders Thorén; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Splanchnic circulation; jejunal mucosal perfusion; laser Doppler flowmetry; cardiopulmonary bypass; cardiac surgery; inotropic agents; gastric tonometry; sympathetic reflex;

   Abstract : Splanchnic ischemia in cardiac surgery is considered a risk factor in the development of the Multiple Organ Dysfunction Syndrome (MODS), which is the leading cause of morbidity and mortality in the intensive care unit. Splanchnic ischemia/reperfusion may lead to an injury of the intestinal mucosa and induce a systemic inflammation (SIRS), which is proposed to precede MODS. READ MORE

5. 13. Skin circulation measured by fluorescein flowmetry

   Author : Eduardo Patricio Proaño Romero; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Skin circulation;

   Abstract : Fluorescein flowmetry (FF) is an indicator dilution technique using sodium fluorescein as an indicator. If the tissue is illuminated with U-V light or blue light, after a bolus injection of the dye, fluorescence is seen in the tissue, and can be measured either photographically or by the video technique.

6. 14. Laser Speckle Contrast Imaging in Reconstructive Surgery

   Author : Johan Zötterman; Simon Farnebo; Erik Tesselaar; Jacob Wikner; Henry Svensson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : ObjectivesReconstructive surgery aims to restore function or normal appearance by reconstructing defective organs after trauma or disease. In patients undergoing reconstructive surgery, previous trauma, surgery or radiotherapy can result in compromised blood supply. READ MORE

7. 15. Photon migration in tissue : laser induced fluorescence for cancer diagnostics and influence of optical properties on microvascular Doppler spectroscopy

   Author : Henrik Nilsson; Othar Svaasand Svansand; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Laser induced flourescence (LIF) is an "optical biopsy" method, based on the selective accumulation of fluorophores in neoplastic tissue. Two recently developed, non-photosensitizing tumor seeking carotenoporphyrins were assessed regarding tumor selectivity, and biodistribution, in experimental animals. READ MORE
