A

HSV-2

27
Q

How do you treat Primary genital herpes in pregnancy if contracted before 28 weeks of gestation?

Aciclovir during the initial infection. Followed by prophylactic aciclovir starting from 36 weeks.
Women that are asymptomatic at delivery can have a normal vaginal delivery.

28
Q

A
  • Kaposi’s Sarcoma
  • Pneumocystis jirovecii pneumonia
  • Cytomegalovirus infection
  • Candidiasis
  • Lymphomas
  • Tuberculosis
31
Q

What tests can be used to monitor HIV?

A

CD4 Count
Viral load

32
Q

What is the CD4 count?

A

The CD4 count is the number of CD4 cells in the blood. These are the cells that are destroyed by the virus.
The lower the count the higher the risk of opportunistic infections

500-1200cells/mm3 is the normal range
<200 cells/mm3 is considered end stage HIV and puts the patient at risk of opportunistic infections

33
Q

What is the Viral load?

A

Viral load is the number of copies of HIV RNA per ml of blood. “Undetectable” refers to a viral load that is below the labs recordable range.

34
Q

How often should women with HIV have smears?

A

They are required yearly.

35
Q

What are the breastfeeding rules for mothers with HIV?

A

HIV can be transmitted during breastfeeding, even if the mothers viral load is undetectable.

36
Q

How does primary syphilis present?

A
  • A painless genital ulcer (chancre) which tends to resolve over 3-8 weeks.
  • Local lymphadenopathy
37
Q

How does secondary syphilis present?

A
  • Maculopapular rash
  • Condylomata lata (grey wart-like lesions)
  • Low-grade fever
  • Lymphadenopathy
  • Alopecia
  • Oral lesions
38
Q

How does tertiary syphilis present?

A

Can present with several symptoms depending on the affected organs. Key features to be aware of are
- Gummatous lesions
- Aortic aneurysms
- Neurosyphilis

Q

What is the treatment for Syphilis?

A

A

MSM
Sex workers
Individuals with multiple sexual partners

42
Q

What investigations are available for syphillis?

A
  • Serological testing: Non-treponemal tests for screening and monitoring treatment response and treponemal tests for confirmation of diagnosis
  • Dark field microscopy: Can be used to directly observe T.Pallidum in samples from primary lesions or secondary rash
  • CSF examination: should be considered in tertiary syphilis
43
Q

What factors can contribute to pH imbalance in the vagina?

A
  • Having multiple sexual partners or a new sexual partner
  • Douching

Q

What is the Jarisch-Herxheimer reaction?

A

It is a systemic inflammatory response to antibiotic treatment, particularly prevalent in syphilis infection but also seen in other spirochetal diseases.

Thought to be a result from the rapid lysis of the bacteria and the subsequent release of endotoxins

51
