Q

what is the oral presentation of crohns

A
  1. crohs unique ulcers
    - linear at depth of sulcus for months
    - full of crohns associated granulomas
  2. aphthous type ulcers caused by haemotinic deficiency - behave like these ulcers

Q

key diagnosis signs for recurrent herpetic lesions and what treatment

A
  1. lesions present along a common nerve branch i.e. MOSTLY one side of hard palate
  2. vesiculation prior to ulcer
  3. caused by herpes zoster or simplex (more likely if painful) or simplex
  4. treatment = SYSTEMIC aciclovir

Q

what is the main rule and sign in diagnosing a ulcerative conditions

A
  • recurrent, self healing ulcers on NON-keratinised mucosa normally Aphthous
  • if on keratinised mucosa then most likely viral
  • if systemic ilness then most likely viral (coxsackie or herpes)

Q

what is recurrent aphthous stomatitis

A
  • immunologically caused RECURRING ulcers
  • genetic basis with environmental modificiaiton
  • follow a specific ulceration pattern depending on which type
  • yellow fibre base of ulcer with erythematus halo

Q

information on minor aphthous ulceration

A
  • <10mm
  • lasts <2 weeks / ulcer
  • ONLY non keratinised tissue
  • can have many
  • phase of ulceration can go away for a long or short time then environmental factor aggrivates and starts again
  • most common type of recurrent ucleraiton
  • react well to topical steroids

Q

information on major aphthous ulcers

A
  • normally >10mm
  • can last for months
  • ANY oral tissue (non-keratinised/keratinised)
  • topical steroids rarely work (need intralesional)
  • can be diagnosed along side minor aphthous ulceration

Q

what is herpetiform aphthae (herpetiform recurrent aphthous stomatitis) and what is its difference to primary herpatic gingivostomatitis and recurrent herpatic lesions

A
  • many SMALL ulcers - 2mm (can coalesce to make bigger)
  • on NON-keratinised tissue (dif. from herpetic lesions)
  • NOT caused by herpes (dif. to herpatic lesions)
  • …UNKNOWN cause
  • rarest form of aphthous ulcers
  • dif. from primary herpatic gingivostomatitis = PHG is on both keratinsied and non keratinised surfaces and PHG gives a fever most likely
17
Q

what is the aphthous ulceration disease that causes both oral and genital symptoms and give infomation on what this is, also what are the two criteria for diagnosing this

A
  • bahçets syndrom
  • inflammation of the blood vessels thus effects oter organs
  • to have this needs 2 of the following to be this disease - genital sores, eye inflammation, skin ulcers, pathergy
  • AND need 3 phases of ucleraiton in a year
  • difference from minor and major aphthous ucleration is that it is debilitating and will have out of the oral cavity consequences
  • linked to many other issues like with the heart and lungs, bowel ulceration, joints and the brain
18
Q

what are conditions that can effect the oral cavity and the genitals involving ulceraiton

A
  1. lichen lanus
  2. vesiculobullous diseases
  3. behçets syndrom
19
Q

environmental aggrivators of RAS

A
  1. pre menstral hormone fluctuations
  2. stress (main)
  3. sharp tooth
  4. nutrient deficiency (iron, B12, folic acid) - cause or a symptom
  5. viral and bacterial infections
20
Q

what is the mechanism that causes ulceration in apthae ulcers and what is the treatment for this

A
  • immunopathology at basal stem cells causing no new cells but shedding of other temporarily 3-4 days later
  • need to treat while immunological activity active (done in the 3-4 days)
  • patient can apply topical steroid if learn tingling sensaiton when occuring
  • or steroid mouthwash prophylaxis all the time
21
Q

tests when suspect an aphthous disease

A
  1. blood tests
    - haematinics (ferritin[iron], folic acid and b12)
    - coeliac disease - TTG
  2. NOT allergy tests, just take out diet and see if gets better
    - chocolate, e numbers (cinnamon, sorbette, benzoate[fizzy drinks])
    - test without eating these for 3 months and if benefit then connection
22
Q

aphthous treatment and managment

A
  1. tx
    - non-steroidal topical for inconvininet lesions
    - steroidal topical for disabling lesions
  2. managment
    - correct blood deficiencies
    - coeliac specialist
    - avoidance of dietary triggers
23
Q

describe the trends in RAS in children

A
  • tend to get ulcers and new shoes - at times of growth (less iron availability)
  • 8-11 and 13-16 yo
24
Q

specialist treatment for vesiculobullous

A
  1. prednisolone systemicly (steroid)
  2. azathiopine (immunosuppresant)
  3. micophenolate (immunosupressant)
