Q

How is vaginal candidiasis diagnosis?

Q

Describe the primary phase of syphilis

A
  1. Presents as a solitary painless genital ulcer known as a chancre

57
Q

Describe the tertiary phase of syphilis

A
  1. One third of latent infections will progress to this stage
  2. Patients can develop cardiac, neurological, auditory abnormalities and gummatous lesions (small, rubbery granulomas with a necrotic center enclosed by a fibrous capsule)
58
Q

How is early syphilis diagnosed?

A

Dark field exam: Remove sample of discharge from chancre and inspect it on a slide; no contrast, so you have to use a black background to see the bacteria

59
Q

How is syphilis diagnosed if there is no lesion present for screening?

A
  1. Non-treponemal testing (VDRL - Venereal Disease Research Laboratory or RPR - Rapid Plasma Reagin)
  2. If non-treponemal testing is positive, Treponemal testing (TP-PA - Treponemal Pallidum particle Agglutination) to confirm diagnosis
60
Q

What are some important things to remember about syphilis diagnostic testing?

A

Non-treponemal testing will become negative over time, and a positive TP-PA will remain positive for the patient’s life

61
Q

What is the treatment for syphilis?

A

Benzathine Penicillin G IM single dose of 2.4 mil units can be used to treat primary, secondary, and early latency phase but does not treat damage caused by tertiary infection
