A case of an 18 year old woman is reported who presented with a pyrexia of unknown origin having returned from a trip to India. She initially had constitutional symptoms only, which rapidly progressed to a multisystem disorder. The difficulty in making the diagnosis of polyarteritis nodosa, especially with the possible differential diagnosis of infection after her recent travel, is discussed. T...

In the current study, the entomotoxic effects of a lectin, extracted from Polygonum persicaria, were determined on Pieris brassicae larvae. The purified molecule significantly decreased larval survival, weight, and mass protein. Different concentrations of P. persicaria agglutinin (PPA) (0.5, 1 and 2 mg/ml) significantly decreased nutritional indices including: the efficiency of conversion of i...

POLYARTERITIS NODOSA is a disease in which widespread acute necrosis occurs in the arteries, leading to a variety of functional disturbances involving the nervous system, heart, kidneys, lungs, abdominal viscera, and blood (Harvey, 1959). The liver is affected in this condition more frequently than is recognized. The following case report illustrates the need for care in the administration of m...

We report a case of bilateral ureteral obstruction most likely caused by polyarteritis nodosa. The diagnosis was based upon muscle biopsy which showed typical necrotizing vasculitis in medium size artery in conjunction with microaneurysms in renal angiography. Ureteral obstruction is a rare manifestation of polyarteritis nodosa. This condition is thought to result from vasculitis of periuretera...

Hemobilia, in patients with the diagnosis of polyarteritis nodosa, is rare at clinical presentation and has a grave prognosis. We describe a case of massive hemobilia, due to aneurysmal rupture, in a patient with polyarteritis nodosa. A 39-year-old man was admitted to the hospital with upper abdominal pain. The patient had a history of partial small bowel resection, for intestinal infarction, a...

Cutaneous polyarteritis nodosa is a rare form of vasculitis relating to small-to-medium-sized arteries. Its etiology is unknown. Clinical manifestations include tender subcutaneous nodules, livedo reticularis, cutaneous ulcers and necrosis. Although it is distinct from systemic polyarteritris nodosa in that it lacks significant internal organ involvement, extra-cutaneous manifestations may be e...

UNLABELLED PREMISE OF THE STUDY We developed 10 novel microsatellite loci for Sagina nodosa, a diploid perennial arctic-alpine herb. To our knowledge, these are the first microsatellite loci for a Sagina species. • METHODS AND RESULTS We performed a low-coverage 454 next-generation sequencing of enriched genomic fragments derived from one individual to generate a massive library of contigs...

Polyarteritis nodosa (PAN) is a systemic vasculitis whose severe forms are treated with glucocorticoids and cyclophosphamide. Refractory patients are exposed to many complications, notably accelerated atherosclerosis. We report a case report of 71-year-old man followed for polyarteritis nodosa refractory to glucocorticoids and cyclosphosphamide. Systemic vasculitis relapses are followed to acce...

Polyarteritis nodosa is multisystem disease with necrotizing vasculitis of middle and small sized arteries. Takayasu arteritis is a rare nonspecific inflammatory disease with unknown cause, predominantly affecting the aorta and its main branches. In the literature, experience about the appropriate graft selection and the long-term patency is reported for vasculitis syndromes such as Takayasu’s ...
