Q

What history do we ask a pt with ulcer?

A

Where is the ulcer?
What size is the ulcer?
What shape is the ulcer?
Does the ulcer begin as a blister and then bursts to produce ulcer? or is it always just been an ulcer?
How long does ulcer last for? - when did it begin (can last several weeks or months if ulcer episode but individual ulcer should last 2 weeks or less if aphthous ulcer)

Q

What must we determine with regards to duration of ulcer?

A

How long pts ulcer free period is - how long they go with no ulcer? - this tells us how inconvenient condition is

Q

Why may trauma cause ulcers?

Appliance such as denture (if so then when dente is removed tissue will heal until re wearing denture), brace, URA, sharp tooth, restoration edge, fractured filling

Q

When might we dx single episode oral ulceration?

A

Pts first presentation with ulcer, no history of recurrence

22
Q

How do we tx traumatic ulcers?

A

Remove traumatic cause
Review pt
In interim we can suggest salt water rinses

23
Q

What primary viruses can cause single episode ulceration?

A

Herpes
Coccsaky Virus

24
Q

How does herpes virus ulceration look?

A

It tends to follow the innervation pattern of the oral mucosa - one side of mouth only

25
Q

If an ulcer is in fact more sinister what may it be?

A

oral squamous cell carcinoma (SCC)

26
Q

What are the types of aphthous ulcers?

A

Minor
Major
Herpetifrom

27
Q

What are the potential causes of rsingle episode oral ulceration?

A
  1. TRauma
  2. First ep of RAU
  3. Viral - herpes or cokksaky virus
  4. Orsal SCC
28
Q

Define minor apthous ulcers

A

Less than 10mm in size
Normally 2-5 lesions but can be up to 20
Mainly affect non-keratinised mucosa
Heal within 14 days
Heal with no scar

29
Q

Define major apthous ulcer

A

> 10mm in size
<5 lesions at a time (1-5)
Affects both keratinised and non-keratinised mucosa
Can take several weeks(6-12 to heal)
Often scar - due to depth of erosion

30
Q

What are herpetiform ulcers?

A

<5mm in size
can have 1-200 ulcers affecting non keratinised mucosa
dont have viral aetiology
dont scar
heal within 14 days

31
Q

What are different types of recurrent oral ulceration?

A

Aphthous ulcers (major, minor, herpetifrom)

Lichen planus
Vesicobullous lesions - pemphigoid, pemphigus, EM
Recurrent viral lesion - herpes
trauma - sharp tooth, resto, denture
systemic disease - crohns, UC

32
Q

What are some vesiculobullous ocniditons that can cause ulceration?

A

Pemphigus
Pemphigoid
Angina bulls HAemorrhagica
Erythema Multiform - TARGET LESIONS (type IV)

33
Q

What are the types of recurrent apthous stomatitis? (RAS)

A

Major
Minor
Herpetifrom
Behcets syndrome

34
Q

What is a RAS?

A

This is a form of conditions where there is immunological damage to the oral mucosa and presents in different patterns dx by history and findings of clinical exam

35
Q

What are triggers of recurrent aphthous stomatitis?

A

Haematinic deficiencies
Systemic diseases - crohns

36
Q

What are the 3 haematinics?

A

Ferrin
B12
Folate

37
Q

What ulcers can crohns disease cause?

A

It can cause a mix of apthous type ulcers usually due to HCT deficiency and also crohns specific ulcers

38
Q

What are crohns specific ulcers?

A

These are lesions that are LINEAR FISSURED ULCERS ALONG SULCUC DEPTH - often seen alongside typical apthous ulcers with oval appearance due to HCT deficiency from crohns itself

last for month s

39
Q

What are the 4 features of a traumatic ulcer?

A

Identifiable cause
Single episode
Lesion will heal once we remove causative factor (not necessarily heal fully just begin to heal and be less prominent)
Halo of keratosis surrounding ulceration with fibrinous cover over the top - trauma due to white change around ulcer suggesting trauma has exceeded tissues capacity for repair and ulcer has occurred as epithelial cells are removed quicker than body can replace them

40
Q

Why do traumatic ulcers have yellow fibrin base and often keratotic halo?

A

There is loss of epithelial cells by trauma which is quicker than the body natural ability to replace ep cells resulting in keratin production

41
Q

What can cause recurrent herpetic lesions?

A

Herpes simplex 1 or 2
Herpes zoster

42
Q

How can we identify herpetic lesions?

A

Lesion is usually limited to one nerve group/branch and are often seen on the HARD PALATE

Ulceration reappears in same area each time - often before ulcer appears pt feels discomfort

43
Q

Why can recurrent herpetic lesions caused by herpes simplex be painful?

A

Not usually due to virus - often due to vesicle which bursts resulting in exposed connective tissue

44
Q

What tx can we provide for recurrent herpetic lesions?

A

Systemic acyclovir - for viral replication suppression - important when lesion is associated with inc nerve damage and possibility of persisting nerve pain after lesion settles

45
Q

What in to history makes us suspicious lesion is herpetic lesion?

A

Oral ulceration that has history of recurring in same place

46
Q

What is the general rule aphthous ulcers?

A

They tend to be self healing ulcers that affect NON KERATINISED MUCOSA

47
Q

What ulcers tend to be self healing affecting non k mucosa only?

A

Apthous

48
Q

What is the general rule for viral caused ulcers?

A

They tend to affect keratinised mucosa and recur

49
Q

What is often the cause of recurring ulceration on k mucosa?

A

Viral cause

50
Q

If ulcer doesn’t heal in 2 weeks what can we do?

A

Urgent cancer pathway
Discuss with hospital specialist and then biopsy
