Q

Aphthous Ulceration:

Minor RAS

A
  • Arise almost exclusively on nonkeratinized mucosa and may be preceded by an erythematous macule in association with prodromal symptoms of burning, itching, or stinging
  • Demonstrate a yellow-white, removable fibrino- purulent membrane that is encircled by an erythematous halo
  • Measure between 3 -10 mm in diameter, demonstrate a variable recurrence rate, and heal without scarring in 7 to 14 days
  • Pain is out of proportion for the size of the ulceration

Aphthous Ulceration:

Major Aphthous Ulcerations- Clinical Features:

A
  • Larger and deeper than minor aphthae with longest duration per episode
  • Measure from 1 to 3 cm in diameter, may have irregular raised borders take from 2 to 6 weeks to heal, and may cause scarring
  • Labial mucosa, soft palate, and tonsillar fauces are involved most commonly

Aphthous Ulceration:

Herpetiform Aphthous Ulcerations - Clinical Features:

A

1 to 2 mm in diameter in clusters of 10 to 100 in groups or throughout the mouth, which usually heal within a few weeks

Q

Aphthous Ulceration:

Clinical Manifestations:

A
  • Burning or itching sensation 24-48 hours before the onset of ulcerations
  • Fever, rash, headache, or lymphadenopathy are typically absent and would suggest a different diagnosis such as herpangina or PFAPA syndrome (periodic fever, pharyngitis, adenitis, and oral ulceration)
  • A history of prior ulceration is typical On physical exam, patients with aphthous stomatitis are well- appearing and afebrile
  • Assess for clinical signs of dehydration, especially in infants and children
  • Involvement of the eye (uveitis) or genitalia suggest other diagnoses, such as Behçet syndrome or MAGIC syndrome (mouth and genital ulcers with inflamed cartilage)

Q

Aphthous Ulceration:

Diagnostic Procedures:

A
  • Diagnosis of aphthous stomatitis is clinical, and laboratory testing is usually unnecessary Diagnostic testing might be considered in persistent, severe, or recurrent cases
  • A CBC demonstrating anemia might suggest hematinic deficiency such as iron, folate, or vitamin B12.
  • Neutropenia might prompt consideration of cyclic neutropenia as a cause of ulcerations
  • Gluten-sensitive enteropathy (celiac disease) present in fewer than 5% of recurrent aphthous stomatitis cases and can be identified with serum anti- endomysial antibody and transglutaminase assay
  • The detection of anti-transglutaminase IgA (tTG) and anti-endomysial (EMA) is used for screening of celiac disease (CD) with a sensitivity and specificity of 90 and 99% respectively
  • Consider HIV testing in cases with complex or severe involvement, persistent herpetiform or major aphthous stomatitis, or those involving keratinized mucosa (adherent gingival, dorsum of the tongue, hard palate)

Q

Aphthous Ulceration:

Treatment:

A

No definitive curative treatment for RAS has been established to date The primary objectives of treatment are to:

  • relieve pain
  • accelerate healing
  • reduce the frequency and severity of episodes of RAS

The approach to therapy should be based on:

  • the severity of symptoms
  • the frequency and duration of the outbreaks
  • the clinical history, and
  • the patient’s ability to tolerate medication

Patients with isolated episodes of simple RAS that last only a few days require no more than topical treatments for relief of pain and a series of general measures, mainly good oral hygiene

Systemic therapy is indicated in patients who experience multiple episodes of RAS and/or severe cases that involve intense pain and difficulty eating and do not respond to topical medication

Despite the frequency of this condition, few high-quality studies have appropriately evaluated treatment of RAS. Therefore, there is no standard therapy. The multiple topical and systemic treatments used have had varying degrees of success

Q

Aphthous Ulceration:

General Measures:

A
  • Oral hygiene: It is important to ensure appropriate oral hygiene and to avoid injury, since this leads to mouth ulcers. We recommend using a soft toothbrush, toothpaste that does not contain sodium lauryl sulfate and an alcohol-free mouthwash
  • Eating: In general, we should try to avoid products that are frequently associated with triggering flare-ups, especially if the patient reports an association with the products
  • Supplements: It is necessary to rule out nutritional deficiencies (e.g., vitamin B12, folic acid, iron, zinc), since in these cases, patients improve when they receive appropriate treatment
