Q

What is the spread of infection facilitated by in PID

A

The spillage of purulent material from the fallopian tubes because they’re hollow
Or via lymphatic spread, which can lead to acute peritonitis and acute perihepatitis (F-H-C)

Q

Is PID common in pregnancies?

A

Rare because the mucous plug acts as a barrier between the uterus and bacteria
Infection can still occur in the 12 weeks of gestation because the mucous plug has not formed, and it can travel
Fetal loss may result

Q

What can decrease the risk of PID?

A

Barrier protection decreases the risk of acquiring most STDs
Oral contraceptives mag decrease the risk of symptomatic PID by increasing cervical mucus viscosity, but this is not proven
Current IUD’s carry a much lower risk of PID than older IUDs- the most significant risk is within the first month after insertion

22
Q

What laparoscopic findings are consistent with PID

A

Tubal erythema
Edema
Adhesions
Purulent exudate or cul-de-sac fluid

23
Q

What do adhesions form from?

A

When there’s a disruption in tissue from trauma infection, etc. the tissue is healing and will form adhesions

24
Q

What does the treatment of PID address?

A

The relief of acute symptoms, eradication of current infection, and minimization of the risk of long-term sequelae

25
Q

What does long-term sequelae include for PID

A

Chronic pelvic pain due to adhesions
Ectopic pregnancy, because adhesions in the fallopian tube can block the egg
Infertility, depending on the degree can block sperm from getting to egg
Implantation failure with in vitro, fertilization attempts

26
Q

What is the treatment of PID? General

A

Therapy with antibiotics alone is successful in 33 to 75% of cases
If surgical treatment is warranted, conservation of reproductive organs is favored by performing simple drainage, adhesiolysis, copious irrigation, or unilateral adnexectomy if possible
Insufficient evidence to recommend removal of IUDs. However, they should be closely followed.

27
Q

What must all regimens be affective against in PID?

A

Chlamydia trachomatis and N. Gonorrhea. As well as gram-negative, facultative organisms, anaerobes and streptococci

28
Q

When should antibiotic therapy be done in PID?

A

Should be initiated quickly, if suspicious of PID and should include empirical broad-spectrum antibiotics

29
Q

When should PID patients be managed as hospitalization

A

Uncertain diagnosis
Pelvic abscess
Pregnancy
Inability to tolerate oral antibiotics
Severe illness
Immunodeficiency (HIV w/ <250 CD4)
IUD
Low likelihood of compliance with outpatient regimen
Failure to improve clinically after 72 hours of outpatient therapy

30
Q

Inpatient treatment of PID regimen a

A
  1. Cefoxitin 2g IV q6hrs OR cefotetan 2g IV q12hrs
  2. Doxycycline 100mg PO or IV q12hrs
31
Q

Inpatient treatment of PID regimen b

A
  1. Clindamycin 900mg IV q8hrs
  2. Gentamicin IV in a loading dose of 2mg/kg, followed by a maintenance dose of 1.5mg/kg q8hrs IV or IM
32
Q

When can IV therapy be discontinued for
PID patients

A

IV Therapy may be discontinued 24 hours after the patient improves clinically
Decreased fever, less tenderness and labs are improving

33
Q

What should be continued in a PID patient after IV antibiotics

A

Oral therapy with 100 mg doxycycline BID x 14d

34
Q

Outpatient treatment of PID regimen a

A
  1. Ceftriaxone 500 mg IM
  2. Doxycycline 100mg PO BIDx 14d
  3. Metronidazole 500 mg PO BID x14d

Give all three
Metronidazole can be added, if suspicion of vaginitis

35
Q

Outpatient treatment of PID regimen b

A
  1. Cefoxitin 2g IM and Probenecid 1g PO
  2. Doxycycline 100mg PO BIDx 14d
  3. Metronidazole 500 mg PO BID x14d

Probenecid helps antibiotics to stay longer in the blood

36
Q

What should a follow up look like for a patient with PID?

A

Reevaluate patients 48 to 72 hours after starting antibiotics
Patients who do not improve in 72 hours, should be reevaluated for possible laparoscopic or surgical intervention
Patient should follow up 3 to 4 weeks after receiving treatment to receive a pelvic exam, STD and HIV prevention counseling, and contraceptive counseling

37
Q

Should sexual partners be treated for patients with PID

A

Anyone who has had sexual contact with a woman with PID in the 60 days preceding the onset of symptoms should be treated empirically for Chlamydia trachomatis and gonorrhea

38
Q

What prevention techniques are there for PID?

A

Improved education, routine screening, diagnosis and empirical treatment

Education should focus on strategies to prevent PID and STDs, including
Reducing the number of sexual partners
Avoiding unsafe sexual practices
Using appropriate barrier protection

39
Q

Complications of PID

A

Tubo ovarian abscess (TOA)
F-H-C syndrome
Infertility
Ectopic pregnancy
Chronic pelvic pain
Endometritis

40
Q

What is a tubo ovarian abscess?

A

An inflammatory mass involving the fallopian tube, ovary, and sometimes adjacent pelvic organs( like the bladder, bowel, etc)

41
Q

What can a tubo ovarian abscess rupture result in?

A

Serious and potentially life-threatening condition
Can result in sepsis, because pus collects in a pocket and forms an abscess, which is released

42
Q

Signs and symptoms of TOA

A

Similar to presentation of patient with PID
Acute lower abdominal pain
+/- fever
Chills
Vaginal discharge

43
Q

What is the most useful and commonly performed study to assess for TOA

A

Pelvic ultrasound or pelvic CT

44
Q

Ultrasound findings of TOA

A

Transvaginal ultrasound image
Shows a complex cyst (appears walled off and you can see white ISH stripes, indicating fluid )and fluid filled tube

45
Q

How can a definitive diagnosis of TOA be made?

A

Only be made with direct visualization of the abscess during an invasive surgical procedure, such as laparoscopy or laparotomy

46
Q

What is the treatment for TOA?

A

Hospitalization is recommended
Same treatment as PID regimen A and B for inpatient
Oral therapy with 100 mg doxycycline BID should be continued for a total of 14 days

47
Q

When is the removal of an IUD indicated?

A

In treatment of TOA because risk of uterine perforation from inflammation

48
Q

What happens if a TOA is not better after 48 to 72 hours of treatment?

A

Surgical intervention is required abscess may have ruptured

49
Q

What is a telltale sign of Fitz Hugh Curtis syndrome?

A

Violin string adhesions caused by spread of gonorrhea and chlamydia infection to the liver capsule and peritoneal surfaces of the right upper quadrant

50
Q

How does a patient with Fitzhugh Curtis syndrome present?

A

Usually present with severe right upper quadrant pain with a pleuritic component (taking a deep breath, radiation of pain)
Pain can radiate to the right shoulder and be confused with cholecystitis

51
Q

What is a treatment for Fitz Hugh Curtis syndrome?

A

Surgical lysis of adhesions, but that could just cause more adhesions

52
Q

What is chronic pelvic pain?

A

Defined as menstrual or non-menstrual pain of at least six months duration, that occurs below the umbilicus, and is severe enough to cause functional disability

53
Q

What is the etiology of chronic pelvic pain?

A

The exact etiology is unknown, the pain most likely results from scarring and adhesions that develop from inflammation during PID

54
Q

What is the link between endometritis and PID?

A

Women with PID are 6 to 10 times more likely to have a diagnosis of endometritis than healthy controls
