Q

What are the major Microbial problems (not STIs)?

A
  • Vulvovaginal Candidiasis
  • Bacterial Vaginosis
  • Balanoposthitis
  • Tinea Cruris
  • Erythrasma
  • Other things that affect skin elsewhere can also affect skin around the genitals e.g. Staph aureus, impetigo or Cellulitis

Q

So how do we diagnose a case of Candidiasis?

A
  • The classic h/o itching and cottage cheese discharge
  • Examination looking for:
    • Fissuring
    • Erythema with satellite lesions
    • Discharge - can also gram stain and culture

Q

How do we treat Vulvovaginal candidiasis?

A

With Azole antifungals:

  • Either Clotrimazole PV
  • Fluconazole PO

If they’re resistant:

  • Do cultures (determine species) and sensitivity tests

Also avoid irritants and treat dermatitis to protect the skin

A
  • Asymptomatic
  • Watery Grey or yellow “fishy smelling” discharge
  • Look for complaints of the smell worsening after sex

Q

How do you diagnose Bacterial Vaginosis?

A
  • History
  • Examination
    • Thin homogenous discharge (smell)

Q

How do we treat bacterial vaginosis?

A
  • Antibiotics
    • Metronidazole (either oral or vaginal gel)
    • Clindamycin (Vaginal)
  • Probiotics
  • Vaginal acidification ⇒ maintain pH < 4.5

Q

What is Plasma Cell Balantitis (Zoon’s Balantitis)?

A

A red area that spreads out from the groin, often with a flaky edge.

17
Q

What is Erythrasma?

A

Similar to Tinea Cruris its a dark area spreading out from the groin.

Caused by Corynebacterium Minutissimum.

18
Q

List some non-microbial causes of genital symptoms

A
  • Dermatoses
  • Structural Abnormalities e.g. a cyst
  • Pain syndromes
  • Trauma
  • Neoplastic
  • Systemic Diseases
  • Perceived problems
19
Q

What are some common traumatic injuries to the genitals?

A

Torn frenulum or ruptured vessels in the penis

20
Q

What systemic diseases commonly affect the genitals?

A

Some autoimmune conditions can cause Lichen Sclerosis; Lichen Planus, itchy white patches on the skin around the genitals.

In lichen sclerosis they commonly appear around the opening to the vagina, anus and penis and can obstruct the openings.

21
Q

Many people present with a complaint but on history and exam they actually have no pathology, what might be the reason for this?

A
  • Regretted sexual encounters including assault
  • Other problems in life
  • Mental health including anxiety
  • Media story, family member or friend recently diagnosed
22
Q

How do we manage a perceived problem?

A
  • Acknowledge it, they must know your not dismissing them
  • Properly test for anything they’re worried about e.g. HIV or cancer or they won’t stop worrying
  • Provide a benign explanation where possible instead of just saying “its normal don’t worry”
23
Q

What are some benign things that can result in people coming to the doctor?

A
  • Fox-Fordyce spots
  • Vulval Papillomatosis
  • Coronal Papillae (pearly papules on the penis)
  • Tyson’s Glands
24
Q

What are Fox-Fordyce spots?

A

Visible sebaceous glands under the skin of the penis/scrotum They’re totally normal, its just because the glands of that area are very big

25
Q

What are common symptoms of a Non-STI genital symptom?

A
  • Discharge from an orifice
  • Pain from somewhere
  • Rashes
  • Lumps and swellings
  • Cuts, sores, ulcers
  • Itching
  • Change in appearance
  • Vague sense of things not being right…
26
Q

What is this?

A

Candida Balantitis

27
Q

What is this?

A

Zoon’s Balantis

28
Q

What are candida Balantitis and Zoon’s Balantis due to?

A

Commensal pathogens

In the case of Zoon’s balantis due to choronic inflammation and/or foreskin malfunction

29
Q

What can a staph pyogens infection lead to?

A

Impetigo

Erysipelas

30
Q

What can Dermatophyte infection lead to?

A

Tinea cruris

31
Q

What is erythrasma?

A

Bacterial skin rash in groin area which is similar to tinea cruris.

32
Q

Treatment of tinea cruris and erythrasma?

A

Steroids + bacterial/fungal treatment

33
Q

What is this?

A

Erythrasma

34
Q

what is this?

A

Tinea cruris

35
Q

Name three pain syndromes and explain them

A
  • Vestibulodynia - Provoked introital tenderness
  • Vulvodynia - Persistent burning or aching
  • Chronic Pelvic Pain Syndrome
    • Sometimes labelled as prostatitis, but usually no ‘itis’.
    • Cause unclear buy muscular dysfunction implicated
36
Q

What are some examples of pain syndromes?

A

-Vestibulodynia

Provoked introital tenderness

-Vulvodynia

Persistent burning or aching

-Chronic Pelvic Pain Syndrome

Sometimes labelled as prostatitis, but usually no ‘itis’.

Cause unclear buy muscular dysfunction implicated

37
Q

Describe the pathogenesis of bacterial vaginosis

A

Overgrowth of predominantly anaerobic organisms (such as Gardnerella vaginalis, Enterococcus faecalis and Actinomyces neuii) and a loss of lactobacilli.

The vagina loses its normal acidity, and vaginal pH increases to greater than 4.5.

  1. Reduction of lactobacili and H2O2 production
  2. Overgrowth of BV associated bacteria
  3. Raised pH

(cycle)

38
Q

What are possible complications of bacterial vaginosis?

A

Usually asymptomative or very mild symtoms

Occasionally:

  • Assc. with endometritis if uterine instrumentation / delivery
  • Assc. with premature labour
  • Increases risk of HIV acquisition
