O salmão-do-atlântico (Salmo salar L., 1758) é uma espécie piscícola migradora icónica dos ecossistemas aquáticos, com um elevado valor económico e cultural, cuja área de distribuição se localiza desde o mar Báltico até ao norte da Península Ibérica. Em Portugal, as populações de salmão encontram-se no limite sul da sua distribuição e, portanto, em condições sub-ótimas associadas com o regime térmico e variaçõe...
O salmão-do-atlântico (Salmo salar) é uma espécie anádroma emblemática do Hemisfério Norte e autóctone em Portugal. Segundo a IUCN o seu estatuto de conservação global é Pouco Preocupante (LC), mas em Portugal encontra-se classificado como Criticamente em Perigo (CR), sendo provavelmente a população desta espécie mais ameaçada à escala global. A sua abundância na Europa diminuiu em toda a área nativa, fruto de ...
Atlantic salmon (Salmo salar L.) are an emblematic anadromous fish species that inhabit marine and freshwater ecosystems in the Northern Hemisphere. In Portugal, the southern limit of its global distribution range, the species is classified as Critically Endangered (CR), and occurs only in the Minho and Lima rivers, which hold the most abundant populations, with occasional confirmed occurrences in the Cávado an...
Ustekinumab is a monoclonal antibody directed against the p40 subunit common to both IL-12 and IL-23 cytokines. Although the evidence of ustekinumab efficacy and safety in clinical trials is extensively recognized, data on its use in clinical practice is limited. Our objective is to report on the real-life experience of two Portuguese dermatology departments with ustekinumab in patients with moderate to severe ...
Blaschkitis and lichen striatus are generally distinguished in the literature by the age of onset, lesion distribution, and histopathology. However, there is currently no clear consensus among authors about whether to consider blaschkitis and lichen striatus different clinical entities or a spectrum ofthe same disease. We present a case of adult BLAISE with features of both lichen striatus and blaschkitis, whic...

Introdução: As infeções fúngicas superficiais são as dermatoses infeciosas mais frequentes e a sua incidência continua a aumentar. Os dermatófitos são os principais agentes causais apresentando, contudo, uma distribuição geográfica variável. Material e Métodos: O presente estudo teve como objetivo a caracterização epidemiológica das infeções fúngicas superficiais diagnosticadas nos Serviços/Unidades de Dermatol...
Annular elastolytic giant cell granuloma (AEGCG) is a rare granulomatous skin disease of undetermined cause, characterized by annular plaques with raised erythematous borders in sun-exposed skin. The typical histologic features are dermal infiltration by multinucleated giant cells, elastin degeneration, and elastophagocytosis. The authors describe a clinical case of AEGCG, which exhibited an excellent response ...
Bullous pemphigoid (BP) is an immune mediated bullous disease that is manifested by urticarial plaques with superimposed subepidermal blisters and significant pruritus. It is generally found in the elderly, but is rare in the pediatric population. A 5-month-old girl previously diagnosed with hand-foot-mouth disease was examined in our dermatology department owing to vesicles and bullae, initially located to the...
