Q
immunologic responce in RAS

9
Q
what questions should be asked in ulcer history
A
- onset - what age

- impact on QOL
10
Q
what questions in medical history should be asked for ulcer diagnosis
A
- any medical problems

what is this
A
minor RAS
14
Q
how may minor RAS present
A
- less than 1cm(<10mm)
- 7-10 days
- non keratinised mucosa
- no scarring
- low number of ulcers
- tend to be on stretchy bits of mouth
15
Q
how may major RAS present
A
- greater than 1cm
- last longer than 2-3 weeks
- can affect all mucosa
- heal with scarring
16
Q
how may herpeteform RAS present
A
- multiple tiny ulcers
- resemble herpetic ulcers
- can coalesce
- keratinised surface
- often effects tongue
- can present with systemic effects
17
Q
what is this
A
herpetiform RAS
18
Q
investigations to diagnose ulcers
A
- if otherwise healthy - RAS
- bloods
- standard (FBC, haematinics, coeliac screen)
- additional (ESR, ANA, viral screens(HIV etc), immunoglobins
- referral to specialists to exclude underlying conditions
- biopsy - +/- direct immunofluorescence
19
Q
what is aphthous like ulceration
A
presentation of RAS in association with variety of systemic disordered and medications
20
Q
what conditions are associated with aphthous like ulceration
A
- bechets
- IBD
- crohns
-ulcerative colitis - HIV
-PFAPA
-sweets
21
Q
1st line management of RAS
A
- diet modification - healthy, no benzoate
-trauma - dentist fix - toothpaste - SLS free
- benzydamine
-lidocaine
-covering agent
-chlorhexidine
22
Q
2nd line management of RAS
A
- topical corticosteroids - betamethasone, hydrocotisone
- topical antibiotics - doxycycline
- vitamin b12
- laser - ablative or non ablative
23
Q
3rd line management of RAS
A
- systemic corticosteroids
-prednisalone
-biologics
-azathioprine
24
what is bechets
- chronic, relapsing, multisysyem, inflammatory vasculitis
- affects large and small vessels
- affects whole body
24
cause of bechets
- unknown
- genetic predisposition
- auto inflammatory disease
25
symptoms/presentation of bechets
- ulcers - RAS- deeper and last longer
- mouth ulcers, genital ulcers, eye inflammation, skin issues, bowel issues, headache
26
how to diagnose bechets
- international criteria for bechets
- 4 = diagnosis
genital ulcers, oral ulcers , ocular lesions = 2
positive pathergy, skin lesion = 1
27
Tx of bechets
- Similar to RAS
- corticosteroids
- covering agent
- lidocaine
28
how to treat traumatic ulcers
remove the cause
29
what is TUGSE
- traumatic ulcerative granuloma with stromal eosinophilia
- self limiting , rare, benign
30
what is the aetiology of TUGSE
- unknown - ulcer stuck in healing
-consider differential diagnosis in patients with
dry mouth
ulcers
complex MH
elderly
31
Tx of TUGSE
- resolution after biopsy
-topical/intra-lesional steroid
32
how may TUGSE present
- side of tongue
-white halo - granulating
-doesn't heal
33
medications which cause ulcers
- cytotoxic drugs - methotrexate
- NSAIDS - ibuprofen , aspirin
- Nicorandil (angina)
34
infections which can cause ulceration
- TB
- HSV 1 and 2
- Primary syphillis infection
- Marcella zoster
-epstein barr virus
35
how may a syphillis ulcer present
- solitary and painless
36
what is this
TUGSE
37
which other conditions can present with ulceration
- lichen planus
-blistering conditions
38
how does ulceration occur in blistering conditions
- unstable epithelium
- if rubbed will blister, collapse and then ulcer
- common on buccal mucosa, FOM and soft palate
39
how may a traumatic ulcer present
- white keratotic border
- causative agent
- surrounding mucosa normal and ulcer soft
40
features of an ulcer which make it a higher cancer risk
- exophytic
- rolled borders
- raised
- hard to touch
41
iatrogenic causes of ulcers
- chemo
-radiotherapy
-graft versus host disease
-drug induced ulceration
42
how may neoplastic ulcer present
- exophytic
- rolled border
- raised
- hard to touch
- non moveable
- not always painful - numbness
- sensory disturbance
