  1. 16. Systemic effects of occupational exposure to arsenic : with special reference to peripheral circulation and nerve function

    Författare :Birgitta Json Lagerkvist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arsenic toxicity; Cold-induced vasospasm; Finger systolic pressure; Nerve conduction velocity; Occupational exposure; Raynaud s phenomenon; Serotonin antagonist;

    Sammanfattning : Smelter workers who were exposed to air-borne arsenic for a mean of 23 years, and age-matched referents, were examined with clinical, physiological, and neurophysiological methods. Exposure to arsenic in workroom air was estimated to have been around the Swedish occupational limits, which were 500 yg/m before 1975 and 50 yg/ra thereafter. LÄS MER

  3. 17. Dynamic mechanical allodynia in peripheral neuropathic pain : psychological observations

    Författare :Monika Samuelsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dynamic mechanical allodynia; Brush-evoked allodynia; Brush-evoked pain; Neuropathic pain; Pain descriptors; Repeatability; Human pain model; Capsaicin; Psychophysical observations;

    Sammanfattning : Introduction and aim: Pain due to a light moving mechanical stimulus, dynamic mechanical allodynia, is a protruding symptom/sign in subgroups of patients with peripheral neuropathic pain and frequently as troublesome as spontaneous ongoing pain. The objective of this thesis was to survey psychophysical details of dynamic mechanical allodynia using a novel semi-quantitative method. LÄS MER

  4. 18. Measuring the tactile sense: Cortical mechanisms and clinical applications of tactile direction discrimination

    Författare :Linda Lundblad; Göteborgs universitet; []
    Nyckelord :AIC; diabetic neuropathy; DLPFC; fMRI; hairy skin; psychophysics; QST testing; somatosensory cortex; tactile direction discrimination;

    Sammanfattning : Most of the studies aiming to investigate the human tactile sense are done on the glabrous skin. Still, there is a need for a quantitative method for evaluating nervous function of the hairy skin. LÄS MER

  5. 19. Quantitative sensory testing, obstructive sleep apnea and peripheral nervous lesions

    Författare :Louise Hagander; Karolinska Institutet; Karolinska Institutet; Karolinska institutet Institutionen för klinisk neurovetenskap Department of Clinical Neuroscience; []
    Nyckelord :MEDICINE;

    Sammanfattning : In diagnosis of peripheral neuropathies, quantitative sensory testing (QST) is used to assess thermal and vibration sensitivity. QST is a psychophysical method susceptible to the influence of several factors. It is important to standardize the test. Vibrations may cause peripheral nerve lesions. LÄS MER

  7. 20. On the function endogenous pain controlling systems in healthy subjects and patients with peripheral or central neuropathic pain

    Författare :Birgitta Tuveson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Painful peripheral neuropathy; Central post-stroke pain; Dynamic mechanical allodynia; Endogenous pain modulation; Heterotopic noxious conditioning stimulation; Quantitative sensory testing; Ondansetron;

    Sammanfattning : Introduction and aim: Activity in the nociceptive system is modulated by descending inhibitory and facilitatory supraspinal endogenous control. Altered balance between inhibition and facilitation has been suggested to at least partly explain the maintenance of some persistent pain conditions. LÄS MER
