New aspects of itch pathophysiology: component analysis of atopic itch using the 'Eppendorf Itch Questionnaire'.
Itch represents a leading symptom in dermatological practice with many psychophysiological aspects. Instruments for qualitative registration of these central nervous factors and evaluation of therapeutic measures are still missing. We analyzed in detail the subjective itch sensation in 108 patients with acute atopic eczema with a new questionnaire developed in analogy to the McGill pain questio...
متن کاملItch in atopic dermatitis - pathophysiology and treatment.
Pruritus is an essential feature of atopic dermatitis with a high impact on the quality of life. Although the pathophysiology of atopic dermatitis itch is not fully understood, recent studies have demonstrated that a variety of mechanisms contribute to the induction and maintenance of the symptom. For example, an increased number of cutaneous nerve fibers and neuropeptides were identified in at...
متن کاملRecent advances in pathophysiology and current management of itch.
The neurophysiology of itch, the dominant symptom of skin disease, has previously received scant attention. Recent advances in the neurophysiology and molecular basis of itch include the use of microneurography to demonstrate the existence of a subset of itch-dedicated afferent C neurons distinct from neurons which transmit pain; use of functional positron emission tomography (PET) and magnetic...
متن کاملInflammatory and Noninflammatory Itch: Implications in Pathophysiology-Directed Treatments
Itch is the main chief complaint in patients visiting dermatologic clinics and has the ability to deeply impair life quality. Itch results from activation of cutaneous nerve endings by noxious stimuli such as inflammatory mediators, neurotransmitters and neuropeptides, causing itch signal transduction from peripheral skin, through the spinal cord and thalamus, to the brain cortex. Primarily non...
متن کاملO6: Pathophysiology of Anxiety Disorders
The most important risk factors for anxiety disorders include genes, early life stress, and current stress. These factors do not act independently but interact with each other throughout human development through examples such as epigenetic modifications and complex forms of learning. The neural substrate of pathological anxiety includes hyperactivity in the amygdala and other limbic brain regi...
