Common variable immunodeficiency is the most common symptomatic primary immune deficiency characterized by hypogammaglobulinemia, recurrent infections, and increased risk of autoimmune disease and malignancy. Secondary amyloidosis develops from chronic inflammatory conditions. The co-existence of CVID (especially in patients with bronchiectasis) and(More)
Clinical examination is very important in the practice of medicine. In patients presenting with a supraclavicular mass, a number of diseases including cancer should be ruled out. Two patients who presented with a bulky left supraclavicular mass were evaluated. Their medical history revealed complaints attributed to lower urinary tract infection. We(More)
Rapidly progressing immunoglobulin A (IgA) nephropathy usually presents with a histological pattern of focal or diffuse necrotizing crescentic glomer-ulonephritis. Antineutrophil cytoplas-mic antibody (ANCA) and its specific antibody to antigen proteinase-3 (an-ti-PR3) are markers of pauci-immune crescentic nephritis, Wegener granulo-matosis, and(More)
The Internet of Things (IoT) is the interconnection of embedded devices and offers the possibility of exploiting cloud-based services to improve control functions. But how much cloud control is possible when facing real-time challenges in a safety-critical environment? This paper provides first insights and data into cloud-based control by means of a(More)
Common variable immunodeficiency (CVID) is a heterogenous group of predominantly antibody-deficiency disorders that make up the greatest proportion of patients with symptomatic primary hypogammaglobulinemia. The rare coincidence of amyloidosis and hypogammaglobulinemia has been reported previously. Contrary to the usual insidious, slowly progressive disease(More)
