• colorectal adenoma
  12 May 2004

  colorectal adenomas ; TA/TVA
  Definition: Adenomas, the benign glandular neoplasms that precede colon cancer development, originate from the intestinal epithelium. They occur singly or multiply. When multiple, the patients may have a genetic predisposition syndrome for colorectal cancer.

  JRC:10442 : cutaneous metastasis of a gastric adenocarcinoma.
  Etiology
  Gastric cancer is thought to result from a combination of environmental factors and the accumulation of specific genetic alterations due to increasing genetic instability, and consequently affects mainly older patients.

• ulcerative colitis
  2 March 2004

  Definition: Ulcerative colitis (UC) is generally considered an inflammatory disorder that always involves the rectum and may also involve more proximal portions of the colon, but always in a diffuse and continuous (non-segmental) fashion.
  Earlier biopsy studies have shown that both rectal sparing and patchy disease may occur during the natural history of UC and may, in fact, be accentuated by oral or enema therapy. (#20410806#)

  Types
  Crohn disease
  Crohn colitis
  ulcerative colitis (hemorragic rectoloitis )
  undeterminate colitis
  Susceptibility
  Genetic association studies have identified 210 risk loci for inflammatory bowel disease, which have revealed fundamental aspects of the molecular biology of the disease, including the roles of autophagy and Th17 cell signaling and development.
  A study identified 26 new genome-wide significant loci, three of which contain (...)

  colorectal cancer, colorectal adenocarcinoma, colonic adenocarcinoma, colorectal carcinoma; colonic carcinomas
  Definition: Adenocarcinoma arising in the colon or rectum.
  Colorectal carcinoma is one of the most common cancers and one of the leading causes of cancerrelated death in the United States. Pathologic examination of biopsy, polypectomy and resection specimens is crucial to appropriate patient managemnt, prognosis assessment and family counseling. Molecular testing plays an (...)

• helminths
  24 November 2004

  Parasitic worms are highly differentiated multicellular organisms. Their life cycles are complex; most alternate between sexual reproduction in the definitive host and asexual multiplication in an intermediary host or vector.
  Thus, depending on parasite species, humans may harbor either adult worms (e.g., Ascarus lumbricoides) or immature stages (e.g., Toxocara canis) or asexual larval forms (e.g., Echinococcus species).
  Once adult worms take up residence in humans, they do not multiply (...)
