1. 6. Neuropathic pain : somatosensory functions related to spontaneous ongoing pain, mechanical allodynia and pain relief

   Författare :Åsa Landerholm; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Peripheral neuropathic pain; Central post stroke pain; Dynamic mechanical allodynia; Static mechanical allodynia; Dysesthesia; Quantitative sensory testing; Spinal cord stimulation.;

   Sammanfattning : Introduction and aim: Patients with neuropathic pain suffer from spontaneous ongoing pain and from abnormal stimulus-evoked pain, e.g., allodynia. LÄS MER

3. 7. Observations on morphology and function of cutaneous and subcutaneous sensory mechanoreceptors : an experimental study in mammals

   Författare :Birgit Stark; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :mechanoreceptors; somatosensory organisation; blood-nerve barrier; Glucose transporter-1; nerve regeneration; TGF-ß family; neurotrophin receptors;

   Sammanfattning : Tactile sensory discrimination is dependent upon an intact system of peripheral mechanoreceptors, their nerve fibre afferents with cell bodies in the dorsal root ganglion and the dorsal column-medial lemniscal system which relays tactile information from the skin to the cortex. Injury to any part of the afferent pathways leads to compromised mechanoreceptive perception. LÄS MER

4. 8. Pedicled and free TRAM flaps in breast reconstructions : a comparative study

   Författare :Åsa Edsander-Nord; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :breast reconstruction; TRAM; pedicled flap; free flap; microdialysis; monitoring; flap circulation; flap metabolism; glucose; lactate; glycerol; abdominal muscles; trunk muscle strength; KIN-COM; quantitative sensory testing; tactile perception threshold; thermal perception threshold; breast volume; thermoplastic; quality of life; SF-36; esthetic evaluation; applanation tonometry;

   Sammanfattning : The transverse rectus abdominis musculocutaneous (TRAM) flap is frequently used when autologous tissue is desired for breast reconstruction, and it can be transferred pedicled or free. The pedicled TRAM flap is elevated as a lower transverse abdominal flap with the rectus abdominis muscle attached in the epigastric area, by which means the deep superior epigastric vessels nourish the flap.

5. 9. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue : positron emission tomography study

   Författare :Alexander Korotkov; Docent Tomas Graven-Nielsen; Umeå universitet; []
   Nyckelord :Experimental muscle pain; Hypertonic saline; Kinesthesia; Proprioception; Movement; Vibration; Muscle fatigue; Brain; Imaging; Positron emission tomography; Regional cerebral blood flow;

   Sammanfattning : Chronic muscle pain is a significant medical and social problem and better understanding of the pathophysiological mechanisms involved is an important requirement for further development of diagnostics, treatment and rehabilitation methods. Experimental imaging studies have investigated functional neuroanatomy of different pain components. LÄS MER

7. 10. Peripheral and central effects of nerve regeneration : Experimental and clinical studies

   Författare :Thomas Hansson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : A nerve injury in the hand often results in profound abnmmalities in sensory perception despite careful alignment and microsurgical repair in order to facilitate accurate nerve regeneration. The present experimental and clinical studies were undertaken in an attempt to functionally evaluate peripheral and central effects of nerve regeneration. LÄS MER
