PFAPA syndrome (Periodic Fever, Aphtas, Pharyngitis and cervical Adenopathies) is one of the causes of periodic fever in pediatrics and it is characterised by high fever, pharyngitis, cervical adenitis and aphtous stomatitis. Its etiopathogeny is unknown. The diagnosis is clinical and the findings of laboratory are unspecified. One or two doses (1 mg/kg) of oral prednisone are enough for a fast resolution of the clinic. It is a benign syndrome and no sequels have been noticed after its disappearance, usually in four years from its beginning. ⋯ Periodic episodes of high fever, pharyngitis and cervical adenitis with a bad response to the conventional treatment should alert us to the PFAPA syndrome. The recognition of this entity will help us to improve the diagnostic and therapeutical focusing, lowering also the anxiety that these cases produce.

ReviewIs Helicobacter pylori infection associated with chronic idiopathic urticaria?
Chronic idiopathic urticaria (CIU) is one of the most frequent skin diseases, however its causes remain unknown in the vast majority of cases. There is increasing evidence for systemic effects of gastric Helicobacter pylori infection, which may result in extra gastrointestinal disorders. Although CIU can result from several causes, a possible relationship between chronic urticaria and Helicobacter pylori has been recently suggested. ⋯ Although some authors found convincing evidence of the involvement of Helicobacter pylori as one possible cause of chronic urticaria, our results have failed to confirm the existence of this etiological association. The most remarkable finding was that those patients who had clinical remission of disease were the ones with greater UBT titters suggesting a role for the amount of colonization by Hp in the pathogenesis of urticaria disease.
