Occasionally, auto-immune diseases may emerge as paraneoplastic syndromes. This is especially recognized in the case of polymyositis/dermatomyostis, but it is an extremely rare event in systemic sclerosis (SSc). The authors report the case of a sixty-year-old woman who presented with Raynaud's phenomenon and rapidly progressing skin thickness of the forearms, hands and lower limbs. Patient evaluation revealed a...
Introdução: Os suportes vasculares restaurativos transitórios (sVRT) foram recentemente aprovados para intervenção coronária percutânea (ICP) na Europa e possuem propriedades muito inovadoras. O objetivo desta declaração de posição é rever criticamente a informação e os estudos com os sVRT disponíveis e contribuir para uma reflexão científica que promova o seu uso racional com orientações estruturadas para a su...
BACKGROUND: Bioresorbable vascular scaffolds (BVS) were recently approved for percutaneous coronary intervention in Europe. The aim of this position statement is to review the information and studies on available BVS, to stimulate discussion on their use and to propose guidelines for this treatment option in Portugal. METHODS AND RESULTS: A working group was set up to reach a consensus based on current evidenc...

The authors present a clinical case of a male, 53-years old with a multiple sclerosis like syndrome, progressive, with 3 years of evolution. The patient also referred dry eye and inflammatory arthralgias, the complementary workup was according with Sjögren's Syndrome. The central nervous system involvement of Sjögren's Syndrome and the difficulty of differential diagnosis with neurological diseases such as Mult...
Recent Hyper Rayleigh Scattering measurements report a significant increase of second-order hyperpolarizability upon introduction of positive charges at the pyridyl end groups in trispyridyl octopolar chromophores. We calculated the geometries, linear response, and first-order hyperpolarizabilities of a series of six trispyridyl molecules both in the neutral and protonated forms. The calculations were performed...
The authors report a clinical case of a 57 years old woman with systemic lupus erythematosus diagnosed 25 years before and secondary amyloidosis. Secondary amyloidosis can be associated with inflammatory or infectious chronic diseases, however the association with systemic lupus erythematosus is rare. We discuss the association between the two entities.
Extraarticular features are usually found in rheumatological diseases sometimes with no correlation with the disease's activity in that moment. Lymphoedema is one of these manifestations and it's defined as a tissue fluid accumulation with gradual onset of swelling of a limb. Because it is an unusual finding, the physiopatological explanation of this feature is still difficult to understand. We describe a case ...
Myxobolus platanus n. sp. infecting the spleen of Mugil platanus Günther, 1880 (Osteichthyes, Mugilidae) from Lagoa dos Patos, Brazil is described The parasites formed round or slightly oval whitish plasmodia (about 0.05-0.1mm in diameter) on the surface of the organ. The spores were round in frontal view and oval in lateral view, 10.7µm (10-11) long, 10.8µm (10-11) wide and 5µm thick, and pre...
