Q

what is urethritis and who gets it?

+ risk factors

A

inflammation of urethra in those who are normally young, biologically male with STIs

so risk factors are unprotected sexual intercourse and multiple sexual partners/ partner with STI

21
Q

name 5 causes of urethritis from most common to least

A

infectious:

  • chlamydia trachomatis
  • neisseria gonorrheoea
  • mycoplasma genitalium

non infectious:

  • chemical irritation - spermicides, soap
  • trauma
22
Q

complications of urethritis?

A

reactive arthritis secondary to c.trachomatis

gonoccocal conjunctivitis

epididimitis

prostatitis

penile lymphangitis

periurethral abscess

23
Q

signs and symptoms of urethritis?

A

dysuria
urethral pruritus
urethral discharge
inflammation of urethral meatus

24
Q

diagnosis of urethritis?

A

diagnostic criteria = 1 or more of the following

mucopurulent/purulent urethral discharge

> 1 leukocytes per oil immersion field of gram stain urethral discharge

positive leukocyte esterase on FIRST CATCH urine

25
what lab tests can you do for urethritis?
urethral discharge microscopy leukocyte esterase on first catch urine NAATs - c.trachomatis, N.gonnorhea
26
what features of a urethritis might point you in the direction of what infection is causing it?
chlamydia = dysuria on its own gonorrhea = purulent discharge herpes Simplex Virus - dysuria + painful genital ulcers
27
what medication do you give for gonococcal urethritis and what classes of abx are they? what other interventions should you suggest?
ceftriaxone (cephalopsorin) + azithromycin (macrolide) barrier protection: condoms abstinence until treated
28
what medication do you give to someone with urethritis causes by chalmydia? what other interventions should you suggest?
azithromycin or doxycycline barrier protection: condoms abstinence until treated
29
what is reactive arthritis and what can you get it from?
seronegative spongyloarthropathy: autoimmune condition also known as reiter's syndrome which causes inflammation of the joints most commonly after an infection (STI or GI) STI is commonly after chlaymdia infection
30
what is PID?
pelvic inflammatory disease: infection of the upper reproductive tract in a woman due to bacterial infection inflaming the mucosa of the uterus, fallopian tubes and ovaries
31
complications of PID?
tubal infertility risk of ectopic pregnancy chronic pelvic pain tubo-ovarian abscess hydrosalpinx fitz-hugh-curtis syndrome
32
what is an infection of the fallopian tubes called? what about if it include the ovaries?
salpingitis | salping-oophritis
33
what is the pathophysiology of what causes the complications of PID - like infertility, ectopic pregnancy, tubo-ovarian abscess, hydrosalpingx
chronic inflammation of the fallopian tubes causes scarring and adhesions causing pockets to form inside them
34
what is fitz-hugh-curtis syndrome/
inflammation from PID spread to the peritoneum this inflammation then spreads to glisson's capsule, which surrounds the liver violin string adhesions which attach the liver to the peritoneum
35
what bacteria most commonly cause PID?
chlamydia trachomatis neisseria gonorrhoeae most of the time its only one type of bacteria but can become polybacterial because one infection makes you more susceptible to another
36
risk factors for developing PID?
Factors related to sexual behaviour, such as: Young age (younger than 25 years). Early age of first coitus. Multiple sexual partners. Recent new partner (within the previous 3 months). History of STI in the woman or her partner. Recent instrumentation of the uterus or interruption of the cervical barrier, such as due to: Termination of pregnancy. Insertion of an intrauterine device (within the past 4–6 weeks, especially in women with pre-existing gonorrhoea or C. trachomatis infection). Hysterosalpingography. In vitro fertilization and intrauterine insemination.
37
symptoms of PID?
Pelvic or lower abdominal pain (usually bilateral). Deep dyspareunia. Abnormal vaginal bleeding (intermenstrual, postcoital, or 'breakthrough'). Abnormal vaginal or cervical discharge. feeling on pelvic fullness dysuria Right upper quadrant pain. - fitz-hugh-curtis syndrome Secondary dysmenorrhoea.
38
signs of PID?
Signs of PID include: Lower abdominal tenderness (usually bilateral). Adnexal tenderness (with or without a palpable mass) cervical motion tenderness, or uterine tenderness (on bimanual vaginal examination). Abnormal cervical or vaginal mucopurulent discharge (on speculum examination). A fever of greater than 38°C, although the temperature is often normal.
39
differentials for PID (lower abdo pain)?
Pregnancy should be ruled out. Other causes of lower abdominal pain in a young woman such as ``` acute appendicitis; endometriosis; irritable bowel syndrome; ovarian cyst rupture, torsion, or haemorrhage; urinary tract infection) ```
40
tests for suspected PID
pregnancy test high vaginal swabs - BV, candiasis test for chlamydia, gonorrhoea + mycoplasma genitalium where possible endocervical or vaginal pus cells (leukocytes) under a microscope on a wet-mount vaginal smear. elevated support diagnosis but non specific: Erythrocyte sedimentation rate (ESR), C-reactive protein, Leucocyte count. offer HIV and syphilis blood tests USS if suspected hydrosalpinx or tuba-ovarian abscess
41
where should PID be managed and why?
in a GUM clinic - facilitate screening for infections and for contact tracing -current and recent partners [within the last 6 months]
42
who should you diagnosis PID in?
A diagnosis of pelvic inflammatory disease (PID) should be considered (and usually empirical antibiotic treatment offered) in any sexually active woman who has recent onset lower abdominal pain associated with local tenderness on bimanual vaginal examination, in whom pregnancy has been excluded and no other cause for the pain has been identified.
43
empirical antibiotics treatment for PID?
Ceftriaxone 1 g as a single intramuscular (IM) dose, followed by oral doxycycline 100 mg twice daily plus oral metronidazole 400 mg twice daily for 14 days. BUT there are different regimens based on age, contraindications etc
44
what should you do if a woman has recently had an IUC inserted and presents with PID?
discuss and remove if she wants it removed but consider removing if symptoms have not resolved after 72 hours either way consider emergency hormonal contraception if removed
45
what is BV?
bacterial vaginosis: characterized by an overgrowth of predominantly anaerobic organisms and a loss of lactobacilli. The vagina loses its normal acidity, and its pH increases to greater than 4.5.
46
what are the risk factors for BV?
Being sexually active — BV is not a sexually transmitted infection (STI), but being sexually active or having concurrent STIs increases the risk of developing BV. The use of douches, deodorant, and vaginal washes; menstruation; and presence of semen in the vagina. Copper intrauterine device. Smoking.
47
what at the signs/symptoms of BV?
Approximately 50% of women with BV are asymptomatic. When symptoms are present, BV is characterized by a fishy-smelling vaginal discharge. It is not usually associated with soreness, itching, or irritation. Examination may reveal a thin, white, homogeneous discharge coating the walls of the vagina and vestibule.
48
how do you treat BV?
Non-pregnant women with asymptomatic BV do not usually require treatment. For symptomatic women (pregnant or non-pregnant): Oral metronidazole is the treatment of choice. if asymptomatic pregnant women: consult obstetrician
49
how do you treat PID?
ibuprofen/paracetamol for the pain empirical antibiotics (ceftriaxone IM, then doxycycline and metronidazole for 2 weeks)
