INTRODUCTION In a large proportion of patients with chronic urticaria, a coexisting autoimmune type of Hashimoto's thyroiditis is being diagnosed. An intradermal test with autologous serum has been generally considered as a screening procedure indicating the presence of triggering autoimmune inflammatory factors in the sera of patients with urticaria. These factors could be possibly involved in...

Metamizol, a pyrazolone derivative, is commonly implicated in IgE-mediated allergic reactions. Skin tests have different sensitivity in drug allergy diagnosis and false positive or false negative results render their interpretation difficult, especially because the ranges of the tested concentrations have not been adequately investigated in all drugs.

We studied 25 men with active scabies and 25 healthy controls. Skin prick tests with standardized house du...
