W1: Somatoform Pain Disorders Fibromyalgia is a Mental or Somatic Disease?

Mental disorders with pain as a leading symptom are remnat diagnostic categories for physicians and psychotherapist, even if they are educated in pain treatment. Patients with somatoform pain disorder (ICD-10: F45.4) are often diagnosed only after several years and multiple diagnostic procedures, in some cases after iatrogenic impairment. The clinical practical features, diagnostic procedure an...

What Color is My Arm? Changes in Skin Color of an Embodied Virtual Arm Modulates Pain Threshold

It has been demonstrated that visual inputs can modulate pain. However, the influence of skin color on pain perception is unknown. Red skin is associated to inflamed, hot and more sensitive skin, while blue is associated to cyanotic, cold skin. We aimed to test whether the color of the skin would alter the heat pain threshold. To this end, we used an immersive virtual environment where we induc...

Discrete Pathophysiology is Uncommon in Patients with Nonspecific Arm Pain

  Background: Nonspecific symptoms are common in all areas of medicine. Patients and caregivers can be frustrated when an illness cannot be reduced to a discrete pathophysiological process that corresponds with the symptoms. We therefore asked the following questions: 1) Which demographic factors and psychological comorbidities are associated with change from an initial diagnosis of nonspecific...

Color Is Not a Metric Space

Using a metric feature space for pattern recognition, data mining, and machine learning greatly simplifies the mathematics because distances are preserved under rotation and translation in feature space. A metric space also provides a “ruler”, or absolute measure of how different two feature vectors are. In the computer vision community color can easily be misstreated as a metric distance. This...
