on 2 week review of acute erythematous candidosis - lesions are unchanged

what do you do now

A

oral rinse to determine fungal
consider nutritional deficiency, HIV, inflammatory

Q

what oral lesions are strongly associated with HIV and why

A

acute necrotising ulceration, kaposi sarcoma, oral hairy leukoplakia, aphthous-ulcers, candidiasis

increased susceptibility to infections due to weakened immune system

Q

how is HIV managed and what is the long-term prognosis

A

ART - antiretroviral therapy, halts replication and allows for normal CD4 count, undetectable viral load

very good long term prognosis if treated

  • any other investigations
  • definitive management
A

T.pallidum = syphilis related ulcer

sexual health clinical, contact tracing

sti testing, blood test for IgG + IgM antibodies

Q

discuss pathophysiology of recurrent herpes simplex

A

primary infection via primary herpetic gingivostomatitis
remains latent in dorsal ganglion, reactivation by trigeminal ganglia via sunlight, injury, trauma, stress, immunosuppression, hormones

17
Q

discuss management of recurrent herpes simplex virus

A

avoid triggers
antivirals for prodrome
acyclovir 5% cream - 2hrs
aciclovir 200mg tabs 5x 5 days

18
Q

what are potential complications of recurrent herpes simplex virus

A

disseminated herpes infection
bells palsy
erythema multiforme
herpetic whitlow
herpetic keratoconjunctivitis

19
Q

pt presents with
“white or red/white speckled buccal mucosa and labial commissure, corners of mouth lesions”

what is differential diagnosis

A

chronic hyperplastic candidosis

20
Q

risk factors for chronic hyperplastic candidosis

A

middle age men
smokers
poor OH
recent broad spectrum abx

diabetes

21
Q

gdp management of chronic hyperplastic candidosis

A

predisposing
systemic fluconazole
careful follow uo
dysplasia management - consider referral for biopsy

22
Q

what should a pt be informed of prior to a biopsy

A

purpose - rule out malignancy, definite diagnosis
procedure details
risks [bleeding, infection, scarring]
aftercare

23
Q

what steps to you take to mitigate risks of biopsy and ensure it is optimal for the reporting histopathologist

A

aseptic technique
atraumatic, LA
biopsy site selection so representative of lesion
adequate sample size
proper handling
clear labelling

24
Q

what features of histology would you see for chronic hyperplastic candidosis

A

hyperkeratosis
inflammatory infiltrate
acanthosis
parakeratosis

25
which stain would you use to highlight organisms in fungal infection
PAS - periodic acid-schiff highlights fungal cell walls
26
what microorganism and what form in chronic hyperplastic candidosis
candida albicans hyphal or pseudohypal
27
how would chronic hyperplastic candidosis be managed in OM any risks associated
potential malignant disorder - 12.1% systemic fluconazole, careful follow up, dysplasia management
