  1. 1. Carpal Tunnel Syndrome and Diabetes. Surgical outcome and nerve pathology

    Författare :Niels Thomsen; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intraepidermal nerve fibre; health-related quality of life; Carpal tunnel syndrome; diabetes mellitus; myelinated nerve fibre; nerve biopsy; nerve conduction study; skin biopsy.;

    Sammanfattning : Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy in the upper extremity. Diabetes mellitus increases the risk of developing CTS from an estimated prevalence of 2-4% in the general population to 15-30% in diabetics. LÄS MER

  2. 2. Effects of nucleus pulposus on nerve root circulation and function. Morphologic and functional studies in an experimental model using porcine spinal nerve roots

    Författare :Gunnar Byröd; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; Nerve root; dorsal root ganglion; intervertebral disc; nucleus pulposus; epidural space; nerve fibre; permeability; blood flow; sciatica;

    Sammanfattning : Sciatica due to lumbar disc herniation has for many decades been viewed as a consequence of mechanical compression exerted on spinal nerve roots by the bulging disc tissues. Recent research has, however, indicated that extruded nucleus pulposus (NP) from the intervertebral disc might cause functional and endoneurial morphological changes in spinal nerve roots, without mechanical compression.

  3. 3. Peripheral nerve function : metabolic features, clinical assessment, and heat shock protein 27

    Författare :Kaveh Pourhamidi; Olov Rolandsson; Lars B Dahlin; Svein-Ivar Mellgren; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Peripheral neuropathy is a common complication among patients with diabetes mellitus, but whether peripheral neuropathy is present in individuals with impaired glucose tolerance (IGT) is debatable. In order to identify and diagnose peripheral neuropathy correctly, it is important to evaluate diagnostic tools that can be implemented in routine health care to assess both large and small nerve fibre function.

  4. 4. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function

    Författare :Carolin Freccero; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; wavelength; sympathetic vasodilatation; sympathetic vasoconstriction; sympathetic nerve function; parasympathetic nerve function; laser Doppler perfusion imaging; laser Doppler perfusion monitoring; finger skin blood flow; fibre separation; contralateral cooling; Concentration; Fysiologi; Cardiovascular system; Kardiovaskulära systemet; Diagnostik; Diagnostics;

    Sammanfattning : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. LÄS MER

  5. 5. Molecular factors influencing nerve growth : studies on the developing rodent trigeminal ganglion and tooth pulp

    Författare :Christina Lillesaar; Ted Ebendal; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The adult tooth pulp has a rich protective sensory innervation from the trigeminal ganglion (TG). The developmental establishment of this exclusively nociceptive innervation is not fully understood today. LÄS MER
