Q

Forms of Candidiasis

A

Many..

20
Q

Psudeomembranous

A

“thrush” white/yellow plaque-red; removable; common in children and geriatric patients

21
Q

erythematous

A

Redness; baldness of tongue (lack papilla); scalded symptom (burned tongue)

22
Q

central papillary atrophy

A

on dorsal surface of tongue- loss of texture in middle of tongue in circle shape-old name is median rhomboid glossitis

23
Q

chronic multifocal

A

many places in the mouth; central pappillary and palate

24
Q

angular cheilitis

A

fungal infection at the corner of the mouth

25
Q

denture stomatitis

A

under the dentures; often asymptomatic

26
Q

Hyperplastic

A

candidiasis-invade epithelium- Will NOT rub off; byproducts are known carcinogens ; topical medications will not work due to penetration

27
Q

Thrush

A

psuedomembranous candidiasis; resembles cottage cheese

28
Q

resembles cottage cheese/curdled milk

A

thrush, or psuedomembranous candidiasis

29
Q

stromatopyrosis

A

burning mouth, thrush

30
Q

Stomatodynia

A

sore mouth; thrush

31
Q

bald tongue

A

erythematous candidias

32
Q

rhomboid glossitis aka central papillary atrophy location

A

@jcn of ant 2/3 and post 1/3 of dorsal tongue

33
Q

Cause of median rhomboid glossitis

A

NOT developmental; caused by candidias; do not treat; triangular loss of pappila

34
Q

Candidiasis that will not rub off

A

chronic hyperplastic-use systemic antifungals

35
Q

therapeutic diagnosis

A

treat without confirming organism; retrospectively note if you were correct

36
Q

Flourhexidine

A

Use commonly for perio diseases and candidiasis

37
Q

Topical or oral for candiadis

A

topical common; use systemic anti fungal when needed

38
Q

Double stranded DNA viruses

A

Herpes

39
Q

HHV-1

A

recurrent, travels in nerve ganglia in latent state

40
Q

reactive HHV

A

traumas (UV, hormones, illness)

41
Q

Asymptomatic shedders

A

shed the virus for 24hrs at a time without showing symptoms-70% of people do

42
Q

Site Specific

A

Recurrent lesions found on vermillion border, attached gingiva (keratinized and to bone), and hard palate (keratinized and to bone)

43
Q

differentiate ulcerus/canker sore cores from HHV

A

canker sores-everywhere except gingiva an d hard palate (where HHV is)

44
Q

Tzanch cells

A

in recurrent herpes simplex; virus travels down the nerve to epithelium; destroys connection between adjacent cells; these cells float around in the blister fluid; these are tzanch cells

45
Q

Diagnosis of Recurrent herpes simplex

A

clinical; or serological (detect antibodies) which is less common
