  1. 1. Accidental hypothermia and local cold injury : physiological and epidemiological studies on risk

    Author : Helge Brändström; Michael Haney; Urban Wiklund; Anders Eriksson; Karl-Axel Ängquist; Ola Winsö; Sigridur Kalman; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cold-related injuries; hypothermia; frostbite; cold adaptation; rewarming; autonomic nervous system; heart rate variability;

    Abstract : Background: (Papers I and II) The objectives were to first determine incidence and contributing factors to cold-related injuries in northern Sweden, both those that led to hospitalization and those that led to fatality.  (Papers III and IV) A further aim was to assess post-cooling hand-rewarming responses and effects of training in a cold environment, both on fingertip rewarming and on function of the autonomic nervous system, to evaluate if there was adaptation related to prolonged occupational cold exposure.

  2. 2. Evaluation of hand skin temperature : Infrared thermography in combination with cold stress tests

    Author : Katarina Leijon Sundqvist; Niklas Lehto; James Mercer; Luleå tekniska universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cold provocation; rewarming; thermoregulation; dynamic IR thermography; Health Science; Hälsovetenskap;

    Abstract : AbstractSince ancient times, warm or cold skin on the human body has been used as a parameter in evaluating health. Changes in body temperature are attributed to diseases or disorders. The assessment of body temperature is often performed to measure fever by detecting an elevated core temperature. READ MORE

  3. 3. Effects of Motion Sickness on Human Thermoregulatory Mechanisms

    Author : Gerard Nobel; Ola Eiken; Nigel A.S. Taylor; KTH; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motion Sickness; autonomic thermoregulation; behavioural thermoregulation; hypothermia; acetylcholine; histamine; Physiology; Fysiologi;

    Abstract : The presented studies were performed to investigate the effects of motion sickness (MS) on human autonomic and behavioural thermoregulatory mechanisms during cold stress and in a thermoneutral environment. The roles of histaminergic and cholinergic neuron systems in autonomic thermoregulation and MS-dependent dysfunction of autonomic thermoregulation were studied using a histamine-receptor blocker, dimenhydrinate (DMH), and a muscarine-receptor blocker, scopolamine (Scop).

  4. 4. Airway responsiveness and exhaled nitric oxide : Studies in asthma and Sjögren's syndrome

    Author : Dóra Lúðvíksdóttir; Uppsala universitet; []
    Keywords : Medical sciences; Airway hyperresponsiveness; nitric oxide; airway inflammation; Sjögren s syndrome; asthma; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Abstract : In this thesis, four different types of provocation agents: methacholine, adenosine, cold air and mannitol were used to study different aspects of the airway responsiveness profile in asthma and Sjögren's syndrome. Exhaled nitric oxide (NO) and markers of eosinophil activation, serum eosinophil peroxidase (S-EPO) and eosinophil cationic protein (S-ECP) were measured. READ MORE

  5. 5. Dynamics of Descending Inhibition and Neuroendocrine Analgesia with special reference to the Trigeminal region

    Author : Anna Feldreich; Karolinska Institutet; Karolinska Institutet; []

    Abstract : In patients with pain, it is of relevance to use clinical assessments that evaluate the pain modulation. In this thesis, the dynamics of descending inhibition or central sensitization and neuroendocrine analgesia were investigated: in healthy volunteers; in patients with chronic closed lock of the temporomandibular joint (TMJ), before and after discectomy; and finally in patients with possible neuropathic pain, (atypical odontalgia).
