Combining bio-logging, stable isotopes and DNA metabarcoding to reveal the fora...

The foraging range of central-place predators is limited by spatiotemporal and energetic constraints. Gadfly petrels Pterodroma spp. are seabirds well adapted to travel vast distances in oceans with sustained wind conditions, although our understanding of their foraging ecology in these heterogeneous and highly dynamic environments is still limited. We studied the foraging behaviour, habitat use, ecological nic...

Myocardial Perfusion in Rheumatoid Arthritis Patients: Associations with Tradit...

Introduction. Cardiovascular (CV) diseases are a major cause of death in rheumatoid arthritis (RA) patients. Novel biomarkers [B-type natriuretic peptide (BNP); osteoprotegerin (OPG)/receptor activator of nuclear factor-kappa B ligand (RANKL) ratio; and dickkopf-1 (DKK-1)] have been used in CV risk assessment. We analysed, in established RA patients, the presence of silent myocardial ischemia and its associatio...

Leg ulcer as a manifestation of eosinophilic vasculitis in a patient with hepat...

Cryoglobulinaemic vasculitis is a complication of hepatitis C virus (HCV) infection, responding to treatment with pegylated interferon (peg-IFN)/ribavirin (RIB), but vasculitis may first appear after treatment with peg-IFN/RIB. A 35-year-old man with HCV infection presented to our department with a 2-month history of a 3.3×3 cm ulcer localised on the right shin, with a regular border, on a violaceous base. Hist...

Colloid milium successfully treated with MAL-PDT

Schimmelpenning syndrome

Schimmelpenning syndrome (SS) includes an organoid nevus that follows the lines of Blaschko and defects of brain, eyes, bones, or other systems. We report a case of a 3-month old female infant, who presented with several thin plaques, with irregular borders, yellowish color, which had a verrucous appearance, following the lines of Blaschko, mainly occupying the left side of posterior trunk, the left face, the r...

Alopécia Areata: Análise Retrospectiva da Consulta de Dermatologia. Pediátrica ...

INTRODUCTION: Alopecia areata usually presents as patchy, nonscarring hair loss. It seems to be an immune mediated disease, whereas genetic predisposition, environmental and psychological triggers may be involved in its aetiology. OBJECTIVES: To study the epidemiology, clinical aspects, associations, and treatment of alopecia areata in the paediatric population of Peadiatric Dermatology outpatients over a 9-yea...

Indeterminate cell histiocytosis in association with acute myeloid leukemia

Indeterminate cell histiocytosis (ICH) is a rare proliferative disorder, in which the predominant cells share morphologic and immunophenotypic features from both Langerhans and non-Langerhans cell histiocytosis. We describe a 62-year-old man presenting a 2-month history of firm nodular lesions on the upper lip. Histopathology, immunohistochemical, and ultrastructural analysis showed typical findings of ICH. The...
