• species
  • Mordella melaena is a species of beetle in the Mordella genus that is in the Mordellidae family, which is a part of the Tenebrionoidea superfamily. (wikipedia.org)
  • Causes
  • Causes of "false" melena include iron supplements, Pepto-Bismol, Maalox, and lead, blood swallowed as a result of a nose bleed (epistaxis), and blood ingested as part of the diet, as with consumption of black pudding (blood sausage), or with the traditional African Maasai diet, which includes much blood drained from cattle. (wikipedia.org)
  • stool
  • Iron supplements may cause a grayish-black stool that should be distinguished from melena, as should black coloration caused by a number of medications, such as bismuth subsalicylate (the active ingredient in Pepto-Bismol), or by foods such as beetroot, black liquorice, or blueberries. (wikipedia.org)
  • While it is reported that melena results in foul-smelling stool, this is sometimes difficult to differentiate from the normal odor. (healthhype.com)
  • symptoms
  • However, aside from the melena itself, many patients may present with few symptoms. (wikipedia.org)
  • Melena strongly suggests, and hematemesis confirms, that bleeding is of upper gastrointestinal origin…Peptic ulcer, the most common cause of gastrointestinal hemorrhage, should be pursued through questions about epigastric distress, the relationship of symptoms to food intake, and a past history of peptic ulcer disease. (wikipedia.org)
  • name
  • Elpis Melena (1818-1899, born as Marie Espérance von Schwartz) was an Anglo-German writer who published under the name of Elpis Melena. (wikipedia.org)
  • Most likely due to the name of a place of early settlers who founded the San Juan de Melena corral, where he later built the first house, which led to the current town. (wikipedia.org)
  • upper
  • However, any bleeding within the upper gastrointestinal tract or the ascending colon can lead to melena. (wikipedia.org)
  • In cases where the source of the bleed is unclear, but melena is present, an upper endoscopy is recommended, to try to ascertain the source of the bleed. (wikipedia.org)
  • small
  • Only blood that originates from a more proximal source (such as the small intestine), or bleeding from a lower source that occurs slowly enough to allow for enzymatic breakdown, is associated with melena. (wikipedia.org)
  • year
  • A 64-year-old man presented with melaena of 2 weeks in duration and with dizziness for the past day. (bmj.com)
  • The 14 of January 1878 is marked the "Ayuntamiento of Melena del Sur", and reorganized in the year 1899. (wikipedia.org)
  • blood
  • A less serious, self-limiting case of melena can occur in newborns two to three days after delivery, due to swallowed maternal blood. (wikipedia.org)
