Q

What is bacterial vaginosis?

A

overgrowth of predominately anaerobic organisms eg Gardnerella Vaginalis.

leads to consequent fall in lactic acid = produces aerobic lactobacilli = raised vaginal ph

Q

What is amsels criteria?
used for?

A

used for bacterial vaginosis

diagnosis of BV - you need 3 of the following 4 :

  • thin white homogenous discharge
  • clue cells on microscopy- stippled vaignal epithelial cells
  • vaginal ph > 4.5
  • positive whiff test - addition of potassium hydroxide = fishy odour

Q

how would you manage a BV patient?

A

asx: no tx. do swab. exception is if woman undergoing pregnancy termination

if symptomatic :
ORAL METRONIDAZOLE FOR 5-7 DAYS.
70-70% initial cure rate. relapse rate> 50% within 3 months.

if adherence issue: single oral dose metronidazole 2g.

topical metronidazole/clindamycin alternative

Q

How to treat BV in pregnant pt?

A

previously they said no oral metronidazole in 1st trimester. NOW YOU CAN :)

TOPICAL CLINDAMYCIN TOO?

if asx: discuss with woman obstretrician

if sx: oral metronidazole 5-7 days or topical tx.

clinical features
serology
microscopic examination of infected tissue.

60
Q

tell me about the serological tests for syphilis investigation?

A

non-treponemal tests:
-not specific for syphilis , might result in false positive
- based on reactivity of serum from infected patients to a cardiolipin-cholesterol-lecithin antigen
- assess the quantity of antibodies being produced.
- becomes negative after treatment
eg: rapid plasma reagin (RPR) and Venereal Disease Research Laboratory (VDRL)

treponemal-specific tests:
- generally more complex and expensive but specific for syphillis
- qualititive only - reported as “reactive” or “non-reactive”
- eg include: TP-EIA (t. pallidum enzyme immunoassay), TPHA (t. pallidum Hemagglutination test)

the TP-EIA is more popular

61

A

pregnancy

SLE, anti-phospholipid syndrome

TB

leprosy

malaria

HIV

62
Q

Interpreting syphilis results

A

positive non-treponemal test + positiv treponemal test : active syphilis infection

positive non-treponemal test + negative treponemal test : false-positive syphilis result eg: due to pregnancy or SLE

negaive non-treponemal test + positive treponemal test : successfully treated syphilis

62
Q

how would you manage syphilis?

A

intramuscular benzathine penicillin - 1st line
alternative : doxycycline

monitor nontreponemal titres (RPR or VDRL) after tx to assess response: should be fourfold decline 1:16 - 1:4. - adequate response.

63
Q

what is the jarisch-herxheimer reaction?

A

seen following syphilis treatment

fever , rash, tachycardia after 1st dose of abx

in contrast to anaphylaxis - no wheeze or hypotension

due to release of endotoxins following bacterial death and typically occurs within few hrs of tx.

no tx needed other than antipyretic if required

64

A

genitourinary

rectum
pharynx

75
Q

incubation period of gonorrhoea?

A

2-5 days

76
Q

male: urethral discharge, dysuria

female: cervicitis eg : leading to vaginal discharge

rectal and pharyngeal infection: usually asx

77
Q

Microbiology of gonorrhoea

A

cant immunise for gonorrhoea

reinfection common due to : - antigen variation of type 4 pili (proteins which adhere to surfaces)
- opa proteins (surface proteins which bind to receptors on immune cells)

78
Q

local complications of gonorrhoea

A

urethral strictures - scarring narrowing the tube that releases urine

what is disseminated gonococcal infection?

what is gonococcal arthritis?

A

DGI: not fully understood.
due to haematogenous spread from mucosal infection (eg asx genital infection).

classic triad:
- tenosynovitis

- dermatitis

later comps:
- septic arthritis
-endocarditis
-perihepatitis (fits-hugh-curtis syndrome)

80
Q

how would you manage gonorrhoea?

A

ciprofloxacin used to be - NOW CEPHALOSPORINS bc 36% resistance in uk to ciprofloxacin

previous 1st line : im ceftriaxone + oral azithromycin.
new 1st line : single dose IM ceftriaxone 1g.

IF SENSATIVES ARE KNOWN: oral ciprofloxacin 500mg

81
Q

what is hiv?

A

RNA retrovirus.

HIV-1 MC.

HIV-2 in west africa.

virus enters and destroys the cd4 t-helper cells of immune system.

initial seroconversion flu-like illness occurs within a few weeks of infection.
the infection is then asx until it progresses to immunodeficiency. - could be years after initial infection.

108
Q

how would you manage hiv?

A

antiretroviral therapy - (ART)

combo of at least 3 drugs

2 nucleoside reverse transcriptase inhibitors (NRTI)

and
either:
- protease inhibitor (PI)
- non-nucleoside reverse transcriptase inhibitor (NNRTI).

this combo decreases viral replication and reduces risk of viral resistance emerging.

109
Q

when to start ART?

A

as soon as diagnosed with HIV

110
Q

entry inhibitors

A

maraviroc( binds to CCR5, prevents interaction with gp41) , enfuvirtide (binds to gp41, fusion inhibitor)

prevent HIV-1 from entering and infecting immune cells

give examples of nucleoside analgoue reverse transcriptase inhibitors (NRTI)

A

zidovudine
abacavir
emtricitabine
didanosine
lamivudine
stavudine
zalcitabine
tenofovir

112
Q

give me some ntri side effects:

A

peripheral neuropathy

tenofovir: renal impairement , osteoporosis

zidovudine: anaemia, myopathy, black nails

didanosine : pancreatitis
