GU + Sexual health Flashcards

1
Q

Bacterial vaginosis

A

The overgrowth of ANAEROBIC bacteria in the vagina, caused by the LOSS of LACTOBACILLI.

NOT AN STI but is a RFx for STIs - can occur alongside other infections

Q

Role of lactobacilli in healthy vagina

A

Produce LACTIC ACID - keeps vagina ACIDIC (<4.5)

When reduced numbers of lactobacilli - becomes ALKALINE allowing ANAEROBIC bacteria to multiply

Q

Sx of bacterial vaginosis

A

Strong fishy odour of watery grey/white discharge

Q

Bacterial vaginosis investigations

A
  • speculum examination to check discharge (not always required if v typical/low risk of STI)
  • VAGINAL SWAB:
    • pH paper shows >4.5
    • CHARCOAL SWAB for MICROSCOPY
      • CLUE CELLS on microscopy (epithelial cells so covered in bacteria their edges are grainy)

Q

Bacterial vaginosis management

A

Asymp = none; generally can self resolve

  • METRONIDAZOLE (only works on ANAEROBIC) - ORAL or VAGINAL GEL
    • 2nd: Clindamyicin
  • Swab for STIs + assess risk of other pelvic infection
  • Give advice/info
      • Don’t drink while on metranidazole

Can prevent with ACIDIFIED VAGINAL GEL

Q

Balanitis Tx

A

Core treatment:

  • Ensuring to clean properly under foreskin
  • 1% hydrocortisone if more severe irritation - for a SHORT TIME

Depends on cause:

    • High potency = lichen sclerosus
  • Antifungal cream
    • topical CLOTRIMAZOLE
  • Antibiotics

A

The transition from the point of viral infection to when the antibodies are made

  • e.g. this the time period when the initial HIV infection presents with flu-like Sx
83
Q

Transmission of HIV

A
  • Unprotected sex (more likely to infect in MSM?)
  • Vertical transmission (pregnancy, birth, breastfeeding)
  • Mucous membrane, blood / open wound exposure to infected BLOOD / Bodily fluids
84
Q

HIV screening

A

Routinely offered at sexual health, antenal and substance misuse services

  • Need to get verbal consent to test tho

The lab test checks for HIV antibodies AND the p24 antigen

  • window period of 45 days = can take up to 45 days for test to turn positive

POC test - only checks Ab
- 90 day window period

Can get home kits if think at risk
- Self-sample (lab)
- PoC test

84
Q

AIDS-defining illnesses

A

Only occur in end-stage HIV infection when CD4 count has dropped (usually < 200)

  • Kaposi’s sarcoma
  • PNEUMOCYSTIS JIROVECII PENUMONIA (PCP)
  • CYTOMEGALOVIRUS
  • OESOPHAGEAL / BRONCHIAL Candidiasis
  • Lymphomas
  • TUBERCULOSIS
85
Q

How is HIV monitored

A
  • CD4 count
    - norm = 500 - 1200 cells/mm3
    - < 200 cells/mm3 = high risk of opportunistic infection
  • HIV RNA -> VIRAL LOAD
    - undetectable if well treated
86
Q

HIV Mx

A

Managed at specialist centres

Antiretroviral therapy (ART)

  • can do Genotypical resistance testing to establish how resistant the HIV strain is to the diff antiretrovirals to guide Tx

Diff classes:

  • Protease Inhib
  • Integrase Inhib
  • Nucleoside reverse transcriptase Inhib
  • Non-nucleoside reverse transcriptase inhib
  • Entry inhib

Usually starting regime = 2 NRTIs (e.g. Tenofovir + Emtricitabine) + a 3rd agent (e.g. Bictegravir)

  • Prophylactic Co-trimoxazole if CD4 count < 200
  • close CVD risk monitoring (as higher risk because of the HIV)
  • YEARLY PAP smear
  • Vaccinate (including PCP) but avoide live vaccines
87
Q

How to prevent HIV transmission during birth

A
  • Viral load < 50 copies/ml = normal delivery is fine
  • > 50 = CONSIDER Pre-labour C-section
  • > 400 = PRE- LABOUR C-SECTION
  • If unknown OR >1000 = IV ZIDOVUDINE during labour

Consider prophyl for babies:

  • Low risk (mum’s viral load <50) = ZIDOVUDINE for 2-4 wks
  • High risk = ZIDOVUDINE, LAMIVUDINE and NEVIRAPINE for 4 WEEKS

Avoid breastfeeding afterwards!

88
Q

Post-exposure prophylaxis (PEP) for HIV

A
  • must be started within LESS thhan 72 HOURS after exposure (sooner the better)
    - not 100% effective
  • ART combination = Emticitabine/tenofovir (Truvada) + raltegravir (for 28 DAYS)

NB can also take Emitricitabine/tenofovir before potential exposure

89
Q

Risk factors for urinary incontinence

A
  • Increasing age
  • Previous preg / child birth
  • High BMI
  • Hysterectomy
  • FHx
90
Q

Classification of urinary incontinence

A
  • Urge incontinence / overactive bladder
    • caused by detrusor overactivity
    • urge is quickly followed by uncontrollabe leakage
  • stress incontinence
    • leaking small amounts when coughing / laughing
  • mixed incontinence
  • overflow incontinence
    • due to bledder outlet obstruction (e.g. enlarged prostate)
  • Functional incontinence
    • Patient can’t get to bathroom in time due to co-morbs
      • e.g. dementia, sedation, injury/illness -> decreased ambulation
91
Q

Initial Ix for urinary incontinence

A
  • MINIMUM 3 DAYS of bladder diary
  • Vaginal exam to exclude pelvic organ prolapse + check ability to initiate colutary contraction of pelvic floor muscles
  • Urine dipstick + cultures (to exclude infection)
  • Urodynamic studies
92
Q

Urge incontinence Mx

A
  1. Bladder retraining (for at least 6 weeks)
  2. Bladder stabilising drugs
    • 1st line = antimuscarinics
      • Oxybutynin (immediate release) (avoid immediate release in frail older women)
      • Tolterodine (immediate release)
      • Darifenacin (OD)
    • Mirabegron (beta-3 agonist) - if worried about anti-muscarinic SE esp in frail older patients
  3. Surgical/invasive
    • botulinum toxin (risk of subsequent overflow incontinence)
    • Sacral nerve stimulation
93
Q

Stress incontinence Mx

A
  1. PELVIC FLOOR MUSCLE TRAINING
    • 8 contractions TDS, for minimum 3 months
    • consider electrical stimulation
    • Vaginal cones
  2. Duloxetine - the SNRI (can increase muscle tone of striated muscle in external urethral sphincter by increasing the synaptic concentration of noradrenaline and serotonin in the PUDENDAL NERVE)
  3. Surgical
    • Colposuspension (lifting and fixing neck of bladder)
    • Sling surgery (placed around neck of bladder) - usually autologous tissue
    • Urethral bulking agenst
    • Artificial urinary sphincter
