BACKGROUND Itch is a major symptom of allergic skin disease. Acupuncture has been shown to exhibit a significant effect on histamine-induced itch in healthy volunteers. We investigated the effect of acupuncture on type I hypersensitivity itch and skin reaction in a double-blind, randomized, placebo-controlled, crossover trial. METHODS An allergen stimulus(More)
BACKGROUND Contact allergy to dental materials is poorly understood; clinical manifestations are heterogeneous. OBJECTIVE To analyse positive patch test reactions to metals (as their alloys or salts) used in dentistry together with clinical symptoms and possible relevance to dental fillings. METHODS We retrospectively analysed 206 patients who underwent(More)
An autoimmune subset of chronic spontaneous urticaria is increasingly being recognized internationally, based on laboratory and clinical evidence that has accrued over the last 20 years. This evidence has been reviewed by a taskforce of the Dermatology section of the European Academy of Allergy and Clinical Immunology. Functional autoantibodies in chronic(More)
The pathogenesis of acute and chronic (> 6 weeks duration) pruritus is complex and involves in the skin a network of resident cells (e. g., mast cells, keratinocytes, sensory neurons) and transient inflammatory cells (e. g., eosinophils). Though pruritus and pain show overlapping mechanisms, recent studies have provided evidence that pruritus and pain(More)
Bronchial asthma represents a severe chronic inflammatory disease with increasing prevalence. The pathogenesis is characterized by complex neuroimmune dysregulation. Although the immunopathogenesis of the disease has been extensively studied, the nature of neuronal dysfunction still remains poorly understood. Recent data indicate that neurotrophins(More)
BACKGROUND Recently, the pivotal role of brain-derived neurotrophic factor (BDNF) has been described in allergic asthma. However, the role of this neurotrophin in atopic dermatitis (AD) still remains unknown. OBJECTIVE The aim of this study was to investigate the functional role of BDNF on eosinophils and to assess BDNF levels in patients with AD and(More)
BACKGROUND Brachioradial pruritus (BRP) describes a rare form of itching occurring at the dorsolateral part of the forearms. Recent case reports suggest that BRP may be attributed to cervical lesions or spine neoplasms. OBJECTIVE We sought to determine the incidence of cervical spine changes in BRP and to correlate the localization of spinal lesions with(More)
Alpha-melanocyte-stimulating hormone (alpha-MSH) is a neuropeptide controlling melanogenesis in pigmentary cells. In addition, its potent immunomodulatory and immunosuppressive activity has been recently described in cutaneous inflammatory disorders. Whether alpha-MSH is also produced in the lung and might play a role in the pathogenesis of inflammatory(More)
