Attempted jugular vein cannulation in a patient with a discrete goitre resulted in a rapid growing haematoma and airway obstruction. This life-threatening complication is rare, and is usually related to two conditions: pre-existing coagulopathy and/or arterial puncture by a large bore cannula or vessel dilator. None of these was present in this patient.(More)
BACKGROUND AND OBJECTIVES Microscopic polyangiitis (MPA) is a systemic small-vessel vasculitis associated with anti-neutrophil cytoplasmic antibodies (ANCA), often targeting myeloperoxidase (MPO). Cyclophosphamide (CYC) plus corticosteroids (CS) is considered standard therapy for patients with renal involvement, but treatment response is not satisfactory in(More)
Spermatogonial stem cells (SSCs) maintain spermatogenesis by self-renewal and generation of spermatogonia committed to differentiation. Under certain in vitro conditions, SSCs from both neonatal and adult mouse testis can reportedly generate multipotent germ cell (mGC) lines that have characteristics and differentiation potential similar to embryonic stem(More)
Myeloperoxidase (MPO)-specific antineutrophil cytoplasmic antibodies have been proposed as pathogenic for microscopic polyangiitis. Supporting this hypothesis, a case report of transplacental anti-MPO antibody transfer presumably causing a vasculitis-like syndrome in the newborn is cited frequently. Here, we report a case of transplacental transfer of high(More)
OBJECTIVE Relapse following remission is common in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), particularly with ANCAs directed at proteinase 3 (PR3). This study was undertaken to evaluate the association of an increase in PR3-ANCA level with subsequent relapse. METHODS Data from the Rituximab versus Cyclophosphamide for(More)
ANCA-associated vasculitides (AAV) are small vessel systemic vasculitis syndromes associated with the potential for high morbidity and mortality. This group includes granulomatosis with polyangiitis (Wegener´s, GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (Churg-Strauss, EGPA). The standard treatment consists of a(More)
Physical exercise (PE) is a regular component in various disorders management, such as ankylosing spondilitis (AS). AS is a chronic and systematic rheumatic disorder without an effective treatment to restore the health. PE plays an important role on the prevention and management of the deformities related to AS. This review summarizes the randomized(More)
Proteinase 3 (PR3)-specific antineutrophil cytoplasmic antibodies (ANCA) are highly specific for the autoimmune small vessel vasculitis, Wegener's granulomatosis (WG). PR3-ANCA have proven diagnostic value but their pathogenic potential and utility as a biomarker for disease activity remain unclear. PR3-ANCA recognize conformational epitopes, and(More)
OBJECTIVE An association between therapeutic inhibition of tumor necrosis factor (TNF) and solid malignancies was observed during the Wegener's Granulomatosis Etanercept Trial (WGET), which included 180 patients with granulomatosis with polyangiitis (Wegener's) (GPA). The present study was conducted to determine the malignancy risk beyond the time of(More)
