- lip involvement + skin manifestations
- primar herpatic gingivostomatitis
Treatment:
- ACYCLOVIR SUSPENSION 200mg in 5ml of water 5 times a day for 5 days

oral symptoms of herpes zoster
- unilateral vesicles
- burst leaving painful herpetic ulcers
What divisions of the trigeminal nerve (5) are effected in varicella zoster virus (herpes zoster)
V1 opthamlic and V2 maxillary
V1= opthalmic herpes zoster ->corneal scarring ->loss of vision
V2= gingival/tooth pain and can be misdiagnosed as pulpitis

Lymphadenopathy
pyrexia
malaise

Kaposi sarcoma clinical features
- often on the palate
- purple/red papules/macules/nodules
- associated with HIV/AIDS
- lymph, GIT, oral, cutaneous
- low CD4+ (normal 500-1500)
How to treat KSHV
- cART
- follow up to check CD4+
- Kaposi sarcoma= surgical excision/cryotherapy/radiothrapy/chemotherapy
What is rosacea
chronic inflammatory facial dermatosis= pustules+erythema+telangiectasia + congested conjunctiva/conjunctivitis/blepharitis/keratitis (corneal scarring)/rhinophyma
-common in fair skin+ blue eyes
EXACERBATED BY= TOPICAL CORTICOSTEROIDS+SUN
Management of rosacea
NO CORTICOSTEROIDS AS THIS EXACERBATES IT
topical metronidazole gel 2 times a day
tetracycline for 2-3 months (causes oral pigmentation)
