Q

Why is it important to have a low threshold of diagnosis for PID? What group is especially at risk?

A

Often missed as can present as non specific signs e.g. abnormal bleeding, dyspareunia, and vaginal discharge

pts at risk:
- sexually active women between the ages of 15 and 24

Q

How would you examine a pt with suspected PID?

A

general:
- include temperature - pyrexial?

Abdo:
- light and deep palpation (looking for bilateral lower abdo tenderness / pain)

Pelvic :
- inspect external genitalia for vaginal discharge - yellow / green?
- speculum examaintion expose cervix (look for mucpurulent or purulent exudate at the endocervix)
- Bi manual examination - cervical excitation or adenexal tenderness

Q

What are the 3 findings looking for on bimanual pelvic examination of a patient with PID (1 or more minimun criteria)

A

Cervical motion tenderness
Uterine tenderness
Adnexal tenderness

24
Q

What other additional criteria (other than minimum criteria) can support diagnosis of PID ?

A

Oral temperature >38.3°C (>101°F)

Abnormal cervical mucopurulent discharge or cervical friability

Presence of abundant numbers of white blood cells on saline microscopy of vaginal fluid

Elevated erythrocyte sedimentation rate

Elevated C-reactive protein

Laboratory documentation of cervical infection with Chlamydia trachomatis or Neisseria gonorrhoeae.

25
Q

You have a pt in A&E who you think has PID but you need to rule of ECTOPIC pregnancy

b) What investigations would you do?

A

(can resemble severe PID. PID can exist concurrently with ectopic pregnancy!)

Investigations:
- Pregnancy test
-Result: hCG high in serum and urine (if ECTOPIC)

US
- empty uterus and mass in fallopian tubes (if ECTOPPIC)

26
Q

You have a pt in A&E who you think has PID but you need to rule of acute appendicitis

b) What investigations would you do?

A

Abdo US
- outer diameter >6mm and aperistaltic / non compressible structure

Abdo / pelvic CT
- appendix >6mmm / calcified apppendicolith present with periappendiceal inflammation

Laproscopy
- confirms diagnosis

27
Q

You have a pt in A&E who you think has PID but you need to rule out ovarian cyst torision

b) What investigations would you do?

A

Pelvic ultrasound confirms diagnosis of ovarian torsion

28
Q

You have a pt in A&E who you think has PID but you need to rule out endometriosis?

What clues in hx endometriosis?
What investigations to confirm endometriosis?

A

signs/ symptoms
- Adnexal enlargement
- lateral displacement of uterus
- cyclic pain that is exacerbated by onset of menses and during the luteal phase; or
- dyspareunia.
( Cyclic pain is not a feature of PID)

Investigations
- Transvaginal US - show ovarian endometrioma / deep pelvic endometriosis e.g. uterosacral ligament involvement

-Laproscopy - diagnose by visualising peritoneal implants and biopsy endometrial glands / stroma outside uterine cavity.

29
Q

What are key features in your history and exam that would point to Ectopic preganncy?

A

History:
Abdo pain - lower or general
ammenorhoea 6-8 weeks
vaginal bleeding
referred shoulder pain
urge to defecate (blood pooling in cul-de-sac)

Examination:
general: orthostatic hypotension / haem instability
Abdominal tenderness (acute e.g. guarding warning sign of rupture)
adnexal tenderness or mass
blood in vaginal vault (in absence of rupture)
cervical motion tenderness

30
Q

A young woman in A&E you are thinking could this be miscarriage or ectopic pregnancy as the cause of acute pelvic pain.
1. What hx /signs / symptoms more likely miscarriage?
2. What investigations / examinations are you doing that would confirm miscarriage?

A
    • vaginal bleeding in the first trimester + abdominal discomfort secondary to uterine contractions.
    • disappearance of pregnancy symptoms e.g. breast tenderness and nausea.

2
- Ultrasound - inter-uterine pregnancy
- pelvic examination - dilation of cervix + tissue at cervical oss
Low HcG and low progesterone

31
Q

What counselling should you give a woman after treatment for PID as primary prevention?

A

Behavioural change is central to the prevention of PID, as potentially modifiable risk factors are associated with PID (e.g., practising safe sex).

High-risk patients should be counselled on safer sex behaviours such as the use of condoms, and the risk of infection with STIs.[20] Counselling and testing for HIV infection should be done where appropriate.

32
Q

What monitoring / follow up should be done for pt with PID

A

Repeat testing of all women who have been diagnosed with chlamydia or gonorrhoea is recommended 3 months after treatment, regardless of whether their sexual partners were treated.

If not possible, test when they next seek medical care <12 months after treatment.

All women diagnosed with PID should be tested for gonorrhoea, chlamydia, HIV, and syphilis

33
Q

A woman has acute pelvic pain. You have ruled out ectopic pregnancy and miscarriage.

What are differentials for acute pelvic pain in non-pregnant women?

Added from BB slides xx

A
  • torsion of ovarian cyst
  • degeneration of fibroid
  • **PID flare up **
  • **haematocolpos **(where there is ablood filled dilated vagina from menstrual bleed in the setting of an anatomical obstruction, e.g. imperforate hymen)
  • Haematometra (retention/collection of blood in uterus due to imperforate hymen or transverse vaginal septum)
  • Pyometra ( accumulation of pus in the uterine cavity resulting from interference with its natural drainage. It is an uncommon condition that occurs mainly in postmenopausal women and is rare in the premenopausal age group)
  • Endometriosis

A

Non pregnant:
Torsion of ovarian cyst
Degeneration of fibroids
Flare of PID
Hematocolpos
Heatometra / Pyometra
Endometriosis

Pregnant:
Torsion of ovarian cyst
degeneration of fibroids
flare up of PID

37
Q

A

Dermoid cysts
heavy, once tort cannot go back to original position

38
Q

outline what you know of a scoring system for women with adnexal torsion?

A
39
Q

What are the clinical features of adnexal torsion (includes ovarian cyst torsion) :

  1. symptoms
  2. Signs

A
39
Q

What are some DDx for ovarian cysts torsion ? Think of discriminatory factors in Hx and clinical features

A
40
Q

What is the diagnosis and treatment of ovarian cysts torsion?

A

Diagnosis
1. USG pelvis (clinical diagnosis if imaging not available - do not delay surgery for further imaging)
2. Tumour markers (don’t delay surgery but if suspicious mass - explore results in follow up)
3. Raised CRP and WCC

Treatment:
1. Admit
2. IV fluids (pts often dehydrated)
3. Pain relief - opiates a lot of pain
4. Surgery either laparotomy or laproscopy

41
Q

What is fibroid degeneration?

A
42
Q

What findings to aid diagnosis of fibroid degeneration?

A

Palpable mass

raised inflammatory markers

43
Q

What is management of fibroid degeneration?

A

Pregnant - conservative management:
- Pain relief (opiates)
- Hydration
- Antibiotic

Emergency surgery:
- indicated if: pedunculated fibroid that has torted to remove it

Hysterectomy:
- if suspicious the fibroid is a sarcoma
- following investigations, MRI imaging and tumour markers

44
Q

What is a triple swab ?
What is included in it / tested for?

A

Outside a sexual health clinic three swabs - ‘triple swab’ used to screen for infection in symptomatic women

note: HVS = high vaginal swab
ECS - endocervical swab
stuarts = charcoal swab

45
Q

A

Bedside:
Pregnancy testing

Lab:
FBC, CRP, WCC
MSU
Triple swabs

Imaging:
USG- pelvis / abdomen
X rya
Diagnostic laparoscopy

46
Q

What is the management of tubo-ovarian abscess

A
47
Q

For tubo-ovarian abscess compare the benefits of laparoscopy and laparotomy

A
48
Q

Is it safe to perform laparoscopy when a woman is pregnant?

A

yes

49
Q

When is a laparoscopy indicated for a pregnant woman?

A

Appendicitis
Cholecystitis
torsion of ovarian cysts

50
Q

What are the main risks for a pregnant woman undergoing a laparoscopy?

A

General anaesthetic
acute inflammatory condition itself -
Fetal loss 1.5% in appendicitis and 4% in cholecystitis

51
Q

Who gets haematocolpos?

A

Younger patients less than 16 yrs old

52
Q

What are the features of haematocolpos?

A

Cyclical pain but NO bleeding

53
Q

What would you see on examination of a pt with haematocolpos and why?

A

Bluish membrane at introitus
becuase: hymen is intact and blood bulges behind it

Pt may be in acute urinary retention - often how picked up once blood released retention improves

54
Q

What is the management of haematocolpos?

A

Admit for immediate incision and drainage by cruciate incision
