25
What does herpangina present like?
Vesicles in the tonsillar/pharyngeal region its a mild condition that presents like PHG with vesicles rupturing to ulceration but further back in the mouth (tonsil pharyngeal region)
26
What is hand foot and mouth?
caused by coxackie A virus Hand, foot and mouth disease is a common infection that causes mouth ulcers and red spots on the hands and feet. It mainly affects children.
27
What does child present with in hand foot and mouth?
Ulcers on the gingival/tongue/cheeks and palate and a maculopapular rash on hands and feet soar throat reluctance to eat
28
What appears a few days after mouth ulcers in hand foot and mouth?
Maculopapular rash on hands and feet
29
What is management like for hand foot and mouth?
Same as herpes simplex 1 - bed rest, stay hydrated, paracetamol if required and will heal in 7-10 days
30
What is an oral ulceration?
Localised defect in surface oral mucosa where covering epithelium is destroyed leaving inflamed area of exposed connective tissue
31
What are the 10 facts we need when taking ulcer history?
onset freq number size site duration exacerbating diet factors lesions in other areas? associated med problems any tx so far that has helped or not helped?
32
What are the 8 causes of oral ulceration?
infection immune mediated disorders vesticulobullous disorders inherited or acquired immunodeficiency disorders neoplastic/haematological trauma vitamin deficiencies recurrent apthous stomatitis
33
What infections can cause ulcers?
herpes simplex hand foot and mouth coxsackie virus syphillis
34
What immune mediated conditions can cause ulcers?
Crohns coeliac
35
What neoplastic/haemotological conditions can cause ulcers?
leukaemia anaemia
36
What causes trauma ulcers?
Physical, thermal or chemical trauma can cause ulceration which will cause ulcer in area of trauma that will resolve approx 2 weeks after causative factor is identified and solved - ie if sharp tooth we manage it and ulcer should resolve within 14 days
37
What vitamin deficiencies can cause ulcers?
iron b12 folate
38
What is recurrent apthous stomatitis?
This is when there is no underlying cause
39
What is the most common cause of ulceration in children?
recurrent apthous ulceration
40
How would apthous ulcers be described as?
Round or ovoid in shape with grey or yellow base and varying degree of perilesional erythema
41
What are the 3 subgroups of recurrent apthous ulceration?
minor major herpetiform
42
What are minor ulcers?
These are under 10mm in size and don't affect keratinised mucosa and tend to heal within 10-14 days
43
Describe the mucosa in the mouth
Keratinized squamous epithelium is present in the attached gingiva and hard palate as well as areas of the dorsal surface of the tongue. Nonkeratinized squamous epithelium covers the soft palate, inner lips, inner cheeks, and the floor of the mouth, and ventral surface of the tongue.
44
What are major ulcers?
These are >10mm in size and can affect keratinised tissue and takes several weeks to heal and can leave residual scarring
45
What are heptiform ulcers?
Ulcers 1-2mm in size, normally multiple present at a time and can be up to 100 present
46
What can heptiform ulcers appear like?
similar to PHG however unlike viral infections they aren't normally accompanied by a fever and can be recurrent
47
What are the causes of recurrent ulcers?
Aetiology unclear - no single causative factor however genetic predisposition holds strongest risk for children developing ulcers where pattern of ulceration changes
48
What are some other causes of recurrent ulcers?
Haematological and deficiency disorders - iron demands increase in childhood and low iron levels and subsequent ulcers can be seen during growth GIT disease such as coeliac - low level of b12 will warrant referral stress allergic disorders hormonal disturbances
49
What allergies can cause ulcerations?
SLS in toothpaste foods with benzoate - chocolate, tomatoes
50
If following history and exam pt is considered to have recurrent apthous ulceration then what should we do?
Often useful to carry out some investigations such as: - diet diary - FBCs - Haematinics - folate/b12/ferritin - coeliac screen
51
If pt is expected coeliac what investigation do we do?
Anti-transglutaminase antibodies
52
How do we manage recurrent ulceration?
Diet analysis to see if any exacerbating food groups low ferritin - 3 months of iron supplementation low b12 or folate then refer to paediatrician positive anti-ttransglutaminase then referral also
53
How can we manage exacerbating factors of ulcers?
we can correct nutritional deficiencies avoid sharp or spicy foods manage traumatic factors allergic facets - diet exclusion, sis free toothpaste
54
What is the main aim of pharmacological intervention in recurrent ulcers?
To prevent superinfection, protect healing ulcers and provide relief of symptoms
55
What do we use to prevention superinfection?
Corsodyl 0.2% mouthwash
56
What do we use to protect healing ulcers?
gengigel topical gel - 3-4 times a day gengigel mouthwash
57
How do we relieve symptoms of ulcers?
benztdamine mouthwash, spray echt (bran - difflam) 0.15%
58
When does OFG begin
Often begins in childhood - average onset of age is 11
59
What is OFG?
rofacial granulomatosis (OFG) is an uncommon condition of the mouth that causes lip swelling, and sometimes swelling of the face, inner cheeks, and the gums.
60
What does OFG appear like?
Identical to oral manifestation of crohns disease - can be future predictor of crohns
61
What causes the clinical features of OFG?
Allergic component which results in lymphoedema and swelling of oral tissues and the presence of non caveating granulomas in oral tissues which prevent normal lymphatic drainage
62
What is the characteristic pathology of OFG?
Non caveating giant cell granulomas which then result in lymphatic obstruction
63
What can OFG be a future predictor of?
Crohns disease
64
What are the clinical features of OFG?
Lip swelling full thickness gingival swelling swelling of non labial facial tissues cobblestone appearance of buccal mucosa mucosal tags lip tongue fissuring angular chelitis deep penetrating ulcers
65
Whats the cause of OFG?
Unknown - limited evidence of genetic predisposition
66
How do we dx OFG?
Mostly by clinical basis as biopsy of lip not essential and can be uncomfy and distressing resulting in additional post op swelling
67
For pts who have clinical OFG dx what do we do?
Consider investigations to aid management and rule out other underlying conditions
68
What are some OFG investigations we can do?
Measure growth - to track weight and height - growth failure or pubertal delay can be see in crohns disease and can indicate this disease FBC - iron deficiency may be present Check for c reactive proteins - usually raised in crohns faecal calcirotein
69
How do we manage OFG in kids?
Can be difficult - needs referral to specialist often support needed with OHI as oral discomfort often present can provide symptomatic relief as per oral ulceration (difflam) manage nutritional deficiencies topical steroids short courses of oral steroids if severe or unresponsive to topical
