Let’s shift gears a little bit and talk about pelvic inflammatory disease or PID. This is a sexually
transmitted disease of the upper female genital tract. It’s a complication of cervicitis.
These patients will have an ascending spread of microorganisms from the lower genital tract
into the upper tract. This can include endometritis, salpingitis, tubo-ovarian abscesses,
pelvis peritonitis, peri-hepatitis. That peri-hepatitis is also known as Fitz-Hugh-Curtis syndrome.
Adolescent females are responsible for one-third of all pelvic inflammatory disease in the United States.
We need to make adolescent females aware of this disease and treat them aggressively when they have it.
Teen girls are at a higher risk for sexually transmitted diseases than even adults.
Chlamydia and gonorrhea have a predilection for columnar cells which are in the cervical os of adolescents.
These cells gradually transform to squamous epithelium during adulthood. Thus, higher rates
of chlamydia and gonorrhea can occur in adolescents and PID is common. There are certain risk factors
for sexually transmitted diseases in children. One is being at a young age with the first sexual encounter.
Having multiple sexual partners, having unprotected sex, having a previous history of pelvic inflammatory
disease or having bacterial vaginosis associated with pelvic inflammatory disease.
So, what are the causes of pelvic inflammatory disease in adolescents? One is Neisseria gonorrhoeae
and another is Chlamydia trachomatis. There are other organisms that can cause this problem
such as Streptococcus, E. coli, Mycoplasma, Ureaplasma, and Bacteroides. Generally, in patients with
urethritis, they’ll have a lower genital tract infection, usually cervicitis. This results in an inflammatory
disruption of cervical barrier which permits ascension of the bacteria up into the uterus.
Then multiple vaginal organisms can follow along route. These patients can get a polymicrobial
upper tract infection. The plasma cells infiltrate the endometrium and this can decrease motility
of fallopian tubes due to inflammation. That can, in turn, lead to a hydrosalpinx or a pyosalpinx.
Thus, patients can get complications and infections of their upper tract. This can include peritonitis,
peri-hepatitis, and a tubo-ovarian abscess. So, let’s talk about what our historical findings
or signs and symptoms that we can see in these patients. First, they usually complain of having
a lower abdominal or pelvic pain or cramping. That’s in about 80%. About half will have a vaginal discharge.
These patients may have dyspareunia or pain while having sex. They can have irregular vaginal bleeding.
And they may have difficulty ambulating secondary to pain. Some call this the PID shuffle.
Other symptoms include dysuria, fever, nausea, and vomiting. When we see a patient with pelvic
inflammatory disease, it’s important to take vital signs. Patients with Fitz-Hugh–Curtis may be very sick.
We need to assess their hemodynamic stability. We have to assess them for abdominal tenderness.
Let’s review the physical exam findings for pelvic inflammatory disease and in particular, the pelvic exam.
The exam with the speculum is not necessary for the diagnosis of PID in an adolescent.
We don’t typically do that. Usually, we defer the pelvic, that part of the pelvic exam
for the regular checkup. However, if a speculum exam is performed, it may reveal vaginal or cervical
discharge and an inflamed cervix. A bimanual exam is critical. We have to check for tenderness
of the uterus, adnexa, and cervix involvement. If there’s cervical motion tenderness,
that definitely raises our concern that this could be PID. So, for the diagnosis of PID, we need at least
one of the following: cervical motion tenderness, uterine tenderness, or adnexal tenderness.
It’s important to get a sense of is it a reliable tenderness or is it just they’re discomfortable
with the bimanual exam. That requires a little bit of experience and some careful observation
of the patient during the exam. Additional criteria supporting a diagnosis of PID include a temperature
greater than 38.3 °C, abnormal cervical or vaginal mucopurulent discharge, the presence of white cells
on a wet mount, an elevated sed rate or a CRP, or a positive test for gonorrhea or chlamydia.
What extra lab findings will we get? Well, we usually check a pregnancy test to make sure
they aren’t pregnant. A CBC may show elevated white count especially in frank PID. A sed rate and a CRP
may be elevated. In Fitz-Hugh-Curtis, the hallmark is elevated liver function test. We will get a urine dip
which will show maybe leukocyte esterase. Vaginal microscopy, a wet mount may show more than 10
white blood cells per high power field. Testing for gonorrhea and chlamydia is indicated
and specifically an NAAT which has to be on the first void, not a clean catch specimen.
Additionally, we will test for other sexually transmitted diseases like syphilis, HIV, et cetera.
In patients with significant adnexal pain or with significant abdominal pain, we may choose to get
a pelvic ultrasound. This can reveal things like fluid-filled fallopian tubes and may be useful to narrow
our differential diagnosis, in other words, to rule out appendicitis or some other cause of pain.
Additionally, the pelvic ultrasound is important for visualization of the tubo-ovarian abscess
which is a surgical emergency. So, how do we treat this? Well, antibiotics are the first line.
Usually, we’ll start with ceftriaxone and doxycycline. Don’t forget to treat sexual partners.
That’s very important to prevent recurrence of disease. What are the indications for hospitalization?
We don’t hospitalize these patients as much as we used to. We used to hospitalize them for education
but it’s turning out that it’s not clear that that’s much better than not hospitalizing them.
That said, we do hospitalize them for surgical emergencies, if they are pregnant, if they’ve failed
or had poor response to outpatient therapy, if they’re incapable of tolerating an outpatient regimen
of say doxycycline, for severe illness, nausea, vomiting, or high fever, or if they are operable
such as a tubo-ovarian abscess. So, what are complications? Well, for a TOA, we worry about bacteria,
inflammatory cells, and fluid in the fallopian tubes. This can then lead to an ovarian abscess
which is quite a complex problem. Also, in patients with fallopian involvement, there’s a risk
for ectopic pregnancy, infertility, and chronic pelvic pain. So to prevent this problem,
we have to educate patients on safer sexual practices and condom use. We have to educate them
about sexually transmitted infections. It’s important also to consider routine screening
of asymptomatic adolescents for sexually transmitted infections. If we can treat the chlamydia early,
it’s less likely to become pelvic inflammatory disease. So, that’s my review of urethritis, cervicitis,
and pelvic inflammatory disease in adolescent patients. Thanks for your time.
