• necrotizing vasculitis
  18 November 2005

  Definition: Necrotizing vasculitis occurs as a primary phenomenon in connective tissue disorders and cognate fields, including polyarteritis nodosa and the Churg and Strauss syndrome variant, rheumatoid arthritis, systemic lupus and Wegener’s granulomatosis.
  In all these conditions focal and multifocal neuropathy occur as a consequence of destruction of the arterial wall and occlusion of the lumen of small epineurial arteries.

• acute gastritis
  10 January 2005

  Definition: Acute gastritis is an cute inflammation in the gastric mucosa is most readily demonstrated as epithelial PMN infiltration, which is never a normal finding.
  Acute inflammation is the presence of extravascular polymorphonuclear neutrophils (PMNs) in the absence of concurrent chronic inflammation.
  Acute gastritis (accompanied by acute mucosal injury) results from many disorders with multifactorial etiologiesand diverse histologic patterns.
  The clinical symptoms, endoscopic (...)

• chronic inflammation
  1 June 2004

  Definition: Inflammation in which mononuclear leukocytes, including lymphocytes, plasma cells (plasmocytes), and macrophages (histiocytes) predominate.
  Occasional small lymphoid aggregates without germinal centers are to be expected, but presence of germinal centers is prima facie evidence of chronic inflammation.
  Prominent numbers of eosinophils and mast cells, and fibrocytes with fibrosis when there is tissue repair, are often included in the overall picture of chronic inflammation. (...)
