RESUMO
We carried out a serological and clinical survey to determine the prevalence and clinical presentation of yaws on two twin islands in Polynesia: Wallis and Futuna. A total of 264 serum samples were tested for specific Treponema pallidum haemagglutinations assay and non-specific rapid plasma reagin: 52 were positive for one or both tests; only one young adult had skin lesion consistent with yaws; and there were no observed cases of secondary or tertiary yaws. Our results contrast with findings in neighbouring islands, such as Vanuatu, where yaws has been reported to resurge. This difference might be explained by better availability and accessibility of healthcare on Wallis and Futuna, thus allowing widespread use of antibiotics for other bacterial diseases.

Acute urticarial lesions may display central clearing with ecchymotic or haemorrhagic hue, often misdiagnosed as erythema multiforme, serum-sickness-like reactions, or urticarial vasculitis. We report a case of acute annular urticaria with unusual presentation occurring in a 20-month-old child to emphasize the distinctive morphologic manifestations in a single disease. Clinicians who care for children should be able to differentiate acute urticaria from its clinical mimics. A directed history and physical examination can reliably orientate necessary diagnostic testing and allow for appropriate treatment.
