A 73-year-old man developed refractory multiple hemorrhagic gastric ulcers. Emergent gastrectomy was performed, and the diagnosis of polyarteritis nodosa was made by histologic evaluation of the resected stomach. Although gastric ulceration is a relatively rare complication of polyarteritis nodosa, it should be considered in the differential diagnosis of refractory hemorrhagic gastric ulcers. E...

The case of a 45 year old man with cutaneous polyarteritis nodosa and Raynaud's phenomenon as initial manifestation of the disease is reported. Although peripheral vascular disease is a well characterised extracutaneous manifestation of cutaneous polyarteritis nodosa, to our knowledge this is the first reported case in which Raynaud's phenomenon was the initial and sole manifestation of the dis...

Methods Pediatric patients of Caucasian Italian origin with the following diseases/manifestations were included in the study: i) histologically confirmed polyartiritis nodosa (PAN) or cutaneous polyartiritis nodosa (cPAN), ii) persistent livedo reticularis with elevation of acute phase reactants, iii) ischemic or hemorrhagic strokes with systemic inflammation. Direct sequencing of CECR1 gene (e...

Drug abuse has been controversially linked to polyarteritis nodosa. A 28-year-old man with a history of drug abuse with inhaled heroin presented with an enigmatic illness consisting of refractory fever, bilateral pleural effusions, migratory polyarthritis, and a leukaemoid reaction. An abdominal angiography confirmed the diagnosis of polyarteritis nodosa, and treatment with both prednisone and ...

Short history of Kawasaki disease, clinical features (principal symptoms and other significant symptoms or findings), diagnosis, cardiovascular involvement, epidemiology. Pathological features (lesion of vessels and lesion of organs exclusive of vessels), comparison between infantile periarteritis nodosa (IPN)/Kawasaki disease and classic periarteritis nodosa (CPN), etiology, treatment and mana...

The association of peculiar giant-cellular granulomatous lesions of the upper respiratory tract and the lungs or other organs with necrotizing vascular lesions resembling polyarteritis nodosa has been seldom reported. Klinger (1931) described one case; R6ssle (1936) one case; Wegener (1939) three case-s; Neumann (1940) four cases; Banowitch, Polayes, and Charet (1942) one case; Lindsay, Aggeler...

The effects of temperature, irradiance, and other environmental variables on photosynthesis in seagrasses are well understood. However, little information is available regarding the nitrate concentration seawater photosynthetic characteristics marine vegetation. Thus, aim this study was to determine effect effective quantum yield seagrass Cymodocea nodosa. nodosa shoots were incubated under dif...
