Dedifferentiated thyroid cancer (DeTC) derived from follicular epithelium is often incurable because it does not respond to radioiodine, radiotherapy, or chemotherapy. In cases, RET/PTC rearrangements are found in 30%-40%, RAS mutations in about 10%, and BRAF mutations in around 40%-50%, with no overlap between these mutations results in papillary thyroid(More)
The hepatitis C virus (HCV) is both hepatotropic and lymphotropic, responsible for a great number of hepatic and extrahepatic immune-system disorders that comprise the so-called HCV syndrome. HCV-associated rheumatic diseases are characterized by frequent clinico-serological overlap; therefore, correct classification of individual patients is necessary(More)
Cryoglobulinemic vasculitis (CV) is an immune-complex-mediated systemic vasculitis involving small-medium sized vessels. A causative role of hepatitis C virus (HCV) in over 4/5 patients has been definitely established on the basis of epidemiological, pathological, and laboratory studies. There is great geographical heterogeneity in the prevalence of CV as(More)
OBJECTIVE The aim of this study was to validate the classification criteria for cryoglobulinaemic vasculitis (CV). METHODS Twenty-three centres were involved. New patients with CV (group A) and controls, i.e. subjects with serum cryoglobulins but lacking CV based on the gold standard of clinical judgment (group B) and subjects without cryoglobulins but(More)
Objectives. Sjögren's syndrome (SS) may be complicated by some neurological manifestations, generally sensory polyneuropathy. Furthermore, involvement of cranial nerves was described as rare complications of SS. Methods. We reported 2 cases: the first one was a 40-year-old woman who developed neuritis of the left optic nerve as presenting symptom few years(More)
S ystemic sclerosis (SSc) is a connective tissue disease characterised by skin and visceral organ involvement. The cause of SSc is still unknown; it has been suggested that one or more factors may be responsible for the disease through a complex pathogenic mechanism. 3 4 Immune system dysregulation, collagen hyperproduction by altered fibro-blasts, and(More)
TNF-alpha blockers represent one of the most important therapeutic strategies for rheumatoid arthritis, but their use has raised the question about their safety profile, particularly in respect to viral infections/reactivations. We describe the case of a patient who developed a symptomatic EBV reactivation 11 days after the first infusion of infliximab.
Sporadic associations between inflammatory myopathies with vaccinations were described in the literature, raising the possible trigger value of vaccines in the development of these autoimmune disorders. Here, we reported the clinical history of 3 patients who developed polymyositis complicated by interstitial lung disease (2 cases) and dermatomyositis (1(More)
In Model-Driven Engineering, UML profiles and MOF-based Domain Specific Modeling Languages (DSMLs) are the most used approaches for describing domain specific applications. The choice of the right approach depends on several aspects, such as tool support, expressivity, complexity of models, company policies. In general, profiled UML models are very much(More)
