Giant Cell Arteritis (GCA) and Takayasu's arteritis (TA) are large vessel vasculitis (LVV) primarily affecting the aorta and its major branches, mainly differentiated by the onset age (>50 years GCA and <40 years TA). In addition, temporal artery involvement and polymyalgia rheumatic are typical features of GCA, but not TA. Imaging techniques are required to secure the diagnosis of large-vessel vasculitides, and to monitor the disease course. Both morphological and metabolic imaging are involved. Morphological imaging is represented mainly by Computerized Tomography (CT), CT angiography, Magnetic Resonance (MR), MR angiography, Color-Doppler Sonography (CDS) and high-resolution CDS...

The first vaccine that shows significant potential in providing broad coverage against serogroup B meningococcal disease has recently been approved. Because of its newness, potential adverse events need to be reported. Here we report a case of urticarial vasculitis, a rare disease in children, in probable relationship with the novel vaccine.

Adult-onset Still's Disease is a rare, idiopathic, inflammatory disorder characterized by arthralgia, evanescent, salmon-colored rash, and daily fevers as well as lymphadenopathy, pharyngitis, splenomegaly, myalgias, and serositis. The inciting etiology of this syndrome is unknown, though it has been hypothesized that infection triggers an autoimmune response. The Yamaguchi Criteria, the most sensitive and widely used diagnostic criteria, requires both a minimum set of criteria to be met as well other potential etiologies to be excluded...

IgA vasculitis (IgAV) is a leukocytoclastic vasculitis and characterized by involvement of small vessels in skin, gastrointestinal system, joints, kidneys, and less frequently other organs. It is the commonest vasculitis in childhood and etiology is not completely known. Neurological manifestations of IgAV are very rare and usually seen in patients with severe hypertension or as an uncommon feature such as peripheral neuropathy. Posterior reversible encephalopathy syndrome (PRES) is a clinic-radiologic entity characterized with temporary vasogenic edema developing typically in posterior circulation of the brain and has been reported as a rare manifestation of IgAV...

Classical polyarteritis nodosa (PAN) is a necrotizing arteritis affecting medium-sized vessels. A 73-year-old gentleman who presented with progressive anemia and scant hemoptysis developed acute kidney injury over the course of hospital admission. Kidney biopsy was initially interpreted as consistent with cephalosporin-associated acute interstitial nephritis (AIN) and acute tubular injury (ATI). After oral prednisone (5 days), the patient was discharged with improving serum creatinine. Two days later, he presented with diffuse alveolar hemorrhage...

Infective endocarditis due to Bartonella bacilliformis is rare. A 64-year-old woman, without previous heart disease, presented with 6 weeks of fever, myalgias, and arthralgias. A systolic murmur was heard on the tricuspid area upon examination, and an echocardiogram showed endocardial lesions in the right atrium. Bartonella bacilliformis was isolated in blood cultures, defining the diagnosis of infective endocarditis using Duke's criteria. Subsequently, the patient developed clinical and laboratory features compatible with antineutrophil cytoplasmic antibody-associated vasculitis...

Objective: To test whether varicella zoster virus (VZV) infection of human brain vascular cells and of lung fibroblasts directly increases proinflammatory cytokine levels, consistent with VZV as a causative agent in intracerebral VZV vasculopathy and giant-cell arteritis (GCA). Methods: Conditioned supernatant from mock- and VZV-infected human brain vascular adventitial fibroblasts (HBVAFs), human perineurial cells (HPNCs), human brain vascular smooth muscle cells (HBVSMCs), and human fetal lung fibroblasts (HFLs) were collected at 72 hours postinfection and analyzed for levels of 30 proinflammatory cytokines using the Meso Scale Discovery Multiplex ELISA platform...

Kawasaki disease (KD) is an acute, self-limited vasculitis affecting young children. It can result in coronary artery abnormalities in a significant proportion of patients, especially if the diagnosis is missed or treatment gets delayed. Echocardiography is the imaging modality of choice for detection of coronary artery abnormalities and assessment of myocardial function. It is also useful for characterization and risk stratification of patients with KD. Echocardiography should be performed at the time of diagnosis and then again at 1-2 weeks and 4-6 weeks after treatment, for uncomplicated cases who do not have significant coronary artery involvement...

Behçet disease (BD) is a variable vessel vasculitis that can involve several organs and systems. Gastrointestinal (GI) involvement has an acute exacerbating course with ulcers, most commonly in the ileocolonic area. These ulcers can be large and deep, causing perforation and massive bleeding. This article highlights the current knowledge on the epidemiology, clinical findings, diagnosis, and management of GI involvement of BD, with emphasis on recent findings.

Gastrointestinal (GI) symptoms are common among patients with systemic lupus erythematosus (SLE), although only rarely are they caused by active organ system involvement from SLE itself. Rapid diagnosis and appropriate treatment of lupus enteritis and other GI manifestations of SLE are critical, because of the potential for organ and life-threatening complications. The 3 main variants of lupus enteritis are lupus mesenteric vasculitis, intestinal pseudo-obstruction, and protein-losing enteropathy. These GI manifestations and others in patients with SLE are reviewed here...

Vasculitis is an inflammatory condition that targets the blood vessels, which may occur in isolation or as a component of a systemic inflammatory condition. Although many of the vasculitides can directly affect the organs of the gastrointestinal system, some types exhibit a proclivity for certain gastrointestinal and hepatic organs. Often a patient presents with nonspecific symptoms, delaying the diagnosis and treatment of the underlying vasculitis. Vasculitis can also present with severe manifestations, such as upper gastrointestinal bleeds and bowel perforation...

Vascular inflammation in small to large veins and arteries contributes substantially to mortality above that of the general population in Behçet's disease. Recent data verified also the presence of accelerated classical subclinical arterial damage (atheromatosis, arteriosclerosis, arterial hypertrophy) even in patients free of overt vascular complications, and may be complementary to that of vasculitis. Early detection of such vascular damage might provide helpful pathophysiological insight and potentially even guide treatment management...

Recently, the number of clinical reports of growing pigs showing neurological signs possibly related to viral infections has increased. The objective of this report was to describe two outbreaks of an atypical condition observed in 6- to 7-week-old pigs with a morbidity of 20% and a fatality rate of 60% in two unrelated farms of the same company. During the acute phase of the disease, fever, sudden death, neurological signs, ear necrosis and occasional corneal opacity were observed. Histopathological examination revealed interstitial pneumonia, lymphoid depletion and lymphocytic vasculitis in different organs and mild polioencephalomyelitis suggesting a potential viral infection...

Idiopathic carotidynia (IC) is a rare and poorly understood syndrome consisting of unilateral neck pain, tenderness, and increased pulsations over the affected carotid bifurcation. A growing body of evidence supports the hypothesis that IC is a distinct clinicopathologic entity with characteristic imaging features. We report the case of a 34-year-old Caucasian male presenting with intense unilateral neck pain in the emergency setting. Computed tomography and ultrasonography revealed fusiform eccentric thickening of the ipsilateral carotid bifurcation without vessel narrowing...

While the usage of illicit drugs in itself carries significant health risks and associated toxicities, drugs that are adulterated to give them volume, alter their psychogenic properties, and make them cheaper to produce are to be considered even more dangerous. Cocaine is one of them, and it is now most commonly being adulterated with levamisole. We report a case of a 37-year-old female with the chief complaint of painful skin lesions and wounds on both of her upper and lower extremities for three weeks duration...
