Angina bullosa haemorrhagica is a condition of the mucous membranes characterized by the sudden appearance of one or more blood blisters within the oral cavity. [1]: 808 The lesions, which may be caused by mild trauma to the mouth tissues such as hot foods, typically rupture quickly and heal without scarring or further discomfort. [2]
Human saliva contains a wide variety of bacteria that are harmless in the mouth, but that may cause significant infection if introduced into a wound. A notable case was a diabetic man who licked his bleeding thumb following a minor bicycle accident , and subsequently had to have the thumb amputated after it became infected with Eikenella ...
Cosmetic deformity is relatively minor, although symptoms may recur in up to 11-13%, of these not all require further treatment. The occurrence of recurrent symptoms is lower (4%) for subtotal parotidectomy. The choice of the surgical procedure is determined by the extent of the disease and the patient’s preference.
Causes: Epstein–Barr virus (EBV) usually spread via saliva [2] Diagnostic method: Based on symptoms and blood tests [3] Treatment: Drinking enough fluids, getting sufficient rest, pain medications such as paracetamol (acetaminophen) and ibuprofen [2] [4] Frequency: 45 per 100,000 per year (U.S.) [5]
Diagramatic representation of mucosal erosion (left), excoriation (center), and ulceration (right) Simplistic representation of the life cycle of mouth ulcers. An ulcer (/ ˈ ʌ l s ər /; from Latin ulcus, "ulcer, sore") [2] is a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissue. [3]
Salivary gland dysfunction affects the flow, amount, or quality of saliva produced. A reduced salivation is termed hyposalivation.Hyposalivation often results in a dry mouth condition called xerostomia, and this can cause tooth decay due to the loss of the protective properties of saliva.
Treatment for angular cheilitis is typically based on the underlying causes along with the use of a barrier cream. [2] Frequently an antifungal and antibacterial cream is also tried. [ 2 ] Angular cheilitis is a fairly common problem, [ 2 ] with estimates that it affects 0.7% of the population. [ 3 ]
Other causes can be duct stricture (narrowing of the duct), infection or injury. Symptoms may include recurrent swelling, pain and aggravation during eating as this is when saliva production is stimulated. Ductal obstruction may cause less saliva flow, which can result in recurrent gland infections. [8]
