wegeners labs
c-ANCA and confirm with PR3 ELISA
allergic contact stomatitis aka
stomatitis venenata
quincke dz aka
angioedema
angioedema aka
quincke dz
types of angioedema (x3)
- IgE hypersensitivity
- ACE inhibitors
- activation of complement pathway - C1 - INH problems (hereditary - type I and II; acquired - lymphoproliferative dz and autoimmune)
transient lingual papillities aka and 3 types
aka lie bumps, tongue torches
- localized – one or several enlarged fungirform papillae - red papule, may ulcerate, dorsal tongue
- generalized – large % of fungiform papillae on tip/laterl tongue dorsum
- diffuse (papulokeratotis): white/yellow asymptomatic papules (poss frictional keratosis)
recurrent aphthous ulcers underlying cellular process
T cell reaction - decreased CD4/CD8 ratio, increased T cell receptors, increased TNF
types of aphthae and alternative names
minor aka mikulicz
major aka sutton or periadenitis mucosa necrotica recurrens
herpetiform
simple and ocmplex aphthosis
simple: few lesions, heal 1-2 weeks, few recurrences
complex: >3 lesions, almost constant
silver nitrate dangers
used for aphthae
can cause massive necrosis and systemic argyria
behcet syndrome aka
Adamantiades syndrome
geography and genetics of behcet
middle east, japan
HLA B51
aphthae in behcet
99% of pts
commonly first sign
more numerous (>6) and dif location (soft palate and oropharynx) than sporadic aphthae
usually minor or majoe
genital lesions in behcet
less frequent, deeper, more scarring than oral
pathergy
positive in behcet
sterile pustule after insertion of sterile needle in skin
behcet classic histo
leukocytoclastic vasculitis: intramural invasion of n/ph, karyorrhexis of n/ph, RBC extravastion an dfibrinoid necrosis of vessel wall
diagnosis criteria for behcet
oral ulcers + 2 of:
- genital lesions
- eye lesions (eveitis, retinal vasculitis, cells in vitrous)
- skin lesions (erythema nodosum, pseudofolliculitis or papulopustular lesions)
or pathergy test
