ulcer

Examples of ulcer in the following topics:

• Genital Ulcer Diseases

  • Genital ulcers are skin ulcers on the genital area caused by sexually transmitted diseases or noninfectious conditions.
  • Genital ulcers are skin ulcers located on the genital area and can be caused by a number of sexually transmitted diseases or other noninfectious conditions such as yeasts, trauma, lupus, rheumatoid arthritis or Behcet's syndrome.
  • Genital ulcers can be painful or painless depending on the type of infection.
  • In about 25% of the cases, the reason for the ulcer will not be identified by laboratory testing.
  • The CDC recommends routine HIV screening for all patients who present with genital ulcers.

• Chancroid (Soft Chancre)

  • Quite often, these enlarged lymph nodes can rupture through the skin and produce draining abscesses.The first symptoms after infection are small painless bumps which quickly become painful ulcers.
  • These ulcers can be quite different in size.
  • The base of the ulcers is usually covered in a gray or yellow substance and bleeds easily.
  • Men often have only one ulcer while women present with multiple ulcers.
  • For proper diagnosis, the other two infectious agents that can present with similar although not identical ulcers need to be excluded.

• Other Infectious Eye Diseases

  • This classic herpetic lesion consists of a linear branching corneal ulcer (dendritic ulcer).
  • In immune deficient patients or with the use of corticosteroids the ulcer may become large and in these cases it is called geographic ulcer.
  • Metaherpetic ulcer results from inability of the corneal epithelium to heal.
  • Summarize the various types of herpes simplex keratitis: dendritic ulcer (epithelial keratitis) and disciform keratitis (stromal keratitis)

• Hydrogen Oxidation

  • They found that it was present in patients with chronic gastritis and gastric ulcers, conditions that were not previously believed to have a microbial cause.
  • It is also linked to the development of duodenal ulcers and stomach cancer.
  • They found that it was present in patients with chronic gastritis and gastric ulcers, conditions that were not previously believed to have a microbial cause.
  • It is also linked to the development of duodenal ulcers and stomach cancer.
  • Testing for H. pylori is recommended if there is peptic ulcer disease, low grade gastric MALT lymphoma, after endoscopic resection of early gastric cancer, if there are first degree relatives with gastric cancer, and in certain cases of dyspepsia, not routinely.

• Fusobacteria

  • The Fusobacterium are associated with infection and disease including periodontal diseases, topical skin ulcers and Lemierres's syndrome.
  • The diseases attributed to Fusobacterium infection involve symptoms that include tissue necrosis, septicemia, intra-amniotic infections and ulcers.

• Lymphogranuloma Venereum

  • The first symptom is usually painless ulcers at the contact area.The secondary stage can manifest from days to months later.
  • Diagnosis is made after serological analysis and exclusion of other reasons for genital ulcers and lymphatic issues.

• Cytophaga and Relatives

  • Columnaris disease is characterized by the presence of ulcerations on the skin and the development of fungus-like patches on the gill filaments.
  • An image of a chinook salmon that has been infected with Cytophaga columnaris and has lesions and ulcerations on the gill.

• Other Fungi Involved in Respiratory Disease

  • More lesions will appear, until a chronic ulcer develops.

• Blastomycosis

  • Skin lesions, usually asymptomatic, that appear as ulcerated lesions with small pustules at the margins

• Epsilonproteobacteria

  • Some strains of this bacterium are pathogenic to humans as it is strongly associated with peptic ulcers, chronic gastritis, duodenitis, and stomach cancer.
