Case Study

Chief Complaint

Oligomenorrhea

Patient Profile

Name: Maria Urbino

Age: 27 years old

Gender: female

History of Present Illness

M.U. is a 27-year-old woman who presents today for evaluation of oligomenorrhea. She reports that her menstrual periods have been irregular for many years. She is seeking care for this issue because she is now in a serious relationship with her boyfriend and they have been discussing getting married and having children. She has never been pregnant or tried to become pregnant before, but she is concerned about her ability to conceive on account of her very irregular menstrual cycle.

She reports that she experienced menarche at age 13. Her periods occurred regularly, every 28 days for the first several years. She recalls that around age 15-16 her periods became irregular with the interval between periods lasting anywhere from 3 weeks to 4 months. She estimates that she has had 4 menstrual periods over the past year. She was not so concerned about this because her mother told her that she has always had the same problem. Many of her friends in high school also had irregular menstrual cycles.

She reports that her menstrual periods usually last about 4-5 days when they occur. She denies any unusually heavy bleeding. She reports some mild lower abdominal cramps and lower back pain with her periods, which are successfully managed with acetaminophen and ibuprofen.

Maria reports that she has been sexually active with one male partner for the past 8 months. Prior to this she reports 3 lifetime partners, all males. She denies any history of sexually transmitted infection. She and her current partner use male condoms for barrier protection against STIs and pregnancy prevention. She is nulliparous. She reports that she had 1 Pap smear, shortly after she turned 21 years. She recalls being told that the results were “normal.”

Maria reports that during later adolescence, around the time that her periods became irregular, she gained a considerable amount of weight. She reports that although her weight has fluctuated slightly over the years, she has been overweight since then. She became tearful as she explained that she has felt very self-conscious of her body since adolescence.

She tearfully explains that she is very anxious about her fertility. She has been very happy in her relationship with her boyfriend, but remains self-conscious about her weight and appearance. She is afraid that he will lose interest in their relationship if she is not able to have children.

Activity: Further Assessment

  1. Given the nature of Maria’s complaints, you decide to proceed with a pelvic exam. Which of the following steps is important to do before starting the pelvic exam in order to maintain the patient’s comfort?
    1. Ascertain the exact date of her last instance of sexual intercourse and ask her to sign a statement attesting to the fact that she has not had intercourse in the last 48 hours prior to the exam.
    2. Position the table in reverse Trendelberg to prevent syncopal episodes.
    3. Place an order for the RN to administer ibuprofen 600 mg by mouth x1 dose prior to the exam to minimize discomfort during and after the exam.
    4. Direct the patient to the restroom so that she may fully empty her bladder prior to changing into the gown for the exam.
    5. Apply a topical antifungal agent to the vaginal introitus to avoid any contamination of the area from the environment.
Answer:

D. Feedback:

It is uncomfortable for a woman to have a full bladder during a pelvic exam, so the opportunity to empty the bladder should be offered before the patient has undressed for the exam. The exact date of last sexual intercourse has no relevance in preparing the patient for the pelvic exam. The patient should be positioned supine on the table with the head and shoulders slightly elevated and the legs in the lithotomy position. There is no reason that patients would routinely require the increased venous return of blood which results from reverse Trendelenberg position. There is no indication for prophylactic pain treatment. There is no indication for prophylactic use of an antifungal agent and doing so would potentially cause harm by altering the microbiome. Additionally, the unnecessary use of antimicrobial agents promotes the emergence of resistance mechanisms in microorganisms.

  1. Based on the history provided, which of the following screening tests is most appropriate to collect for this patient?
    1. Gonorrhea and chlamydia NAAT testing from cervical os swab every year
    2. Vaginitis panel to test for bacterial vaginosis, vulvovaginal candidiasis and trichomoniasis via NAAT testing
    3. Urine sample via straight catheter to send for urine culture
    4. Endocervical brush sample for Pap Smear
Answer:

D. Feedback:

During the interview, the patient shared that her only Pap smear had been done when she was 21 years old, about 6 years ago. For women aged 21-29, The United States Preventative Services Task Force (USPSTF) recommends cervical cancer screening every 3 years if done with cytology alone or every 5 years if done with high-risk human papilloma virus (HPV) testing alone or every 5 years if done with co-testing of cytology and high-risk HPV testing (USPSTF, 2018). Therefore, our patient is due for repeat screening regardless of what testing she had done 6 years ago.

Gonorrhea and chlamydia screening for women aged 25 or older is recommended for women with increased risk for infection based on sexual practices (USPSTF, 2021). Based on the history provided, this patient does not have increased risk for gonorrhea or chlamydia infection; however, screening should be offered to sexually active women who have not been screened since sexual activity began with a new partner.

A vaginitis panel uses DNA amplification techniques to test for the presence of microorganisms which can cause vulvovaginal candidiasis, bacterial vaginosis, and trichomoniasis. It is a diagnostic test, not a screening test. Therefore it is not an appropriate test to use when the patient does not have any signs or symptoms of the condition. This is the same issue with collecting a urine culture.

Case Study Continued

Pelvic Exam Findings

No inguinal adenopathy. There is acanthosis nigricans in the inguinal skin folds. No lesions, erythema or masses of the external genitalia. Pubic hair of normal distribution for adult female. Vaginal mucosa is pink with no visible lesions. There is a moderate amount of whitish/clear discharge in the vaginal canal. Uterus is anterior, midline, smooth, and not enlarged. Cervical os is visualized with no drainage noted. No cervical motion tenderness with bimanual exam. Slight tenderness with adnexal palpation bilaterally. Ovaries are not palpable. No adnexal masses palpated.

Diagnostic Reasoning

You have included polycystic ovarian syndrome (PCOS) in your differential diagnosis. The Rotterdam criteria are the recommended diagnostic tool for identifying patients with PCOS (Barbieri & Ehrmann, 2024b).

Table 1. Rotterdam Criteria for the Diagnosis of Polycystic Ovarian Syndrome (PCOS)
Two of the listed criteria are required to make the diagnosis of PCOS Oligo- and/or anovulation
Clinical and/or biochemical signs of hyperandrogenism
Polycystic ovaries by ultrasound

Review Questions

Click the arrow to expand the section and view the correct answers.

  1. Based on your evaluation, you suspect that Maria has polycystic ovarian syndrome (PCOS) because she has clinical manifestations of two out of three Rotterdam criteria. From the box, select the two criteria that are evident in your evaluation of Maria and are included in the Rotterdam Criteria
    1. Oligomenorrhea or amenorrhea
    2. Hyperandrogenism
    3. Polycystic ovaries
    4. Metabolic syndrome
    5. Pelvic inflammation
Answer:

A. Feedback:

Maria’s history is consistent with oligomenorrhea based on the duration between menstrual cycles often being longer than 35 days and having had only 4 menstrual cycles completed over the past year.

The physical exam in the case study describes acne, hirsutism, and female pattern hair loss. All of these findings are clinical manifestations of hyperandrogenism (Barbieri & Ehrmann, 2024a).

At this time, we do not know if she has polycystic ovaries on ultrasound because no imaging studies have been done yet. Metabolic syndrome and pelvic inflammation are not part of the Rotterdam criteria.

  1. One reason that it is important to make a timely diagnosis of PCOS for affected patients is that the syndrome is associated with increased risk for other serious conditions. After PCOS has been diagnosed, you should consider screening for which two conditions:
    1. Ovarian cancer
    2. Breast cancer
    3. Dyslipidemia
    4. Type 2 diabetes
    5. Ulcerative colitis
    6. Pelvic organ prolapse
Answer:

C & D. Feedback:

PCOS is associated with increased risk of dyslipidemia and type 2 diabetes, both of which increase the patient’s cardiometabolic risk profile. Therefore, a fasting lipid panel is recommended to evaluate for dyslipidemia at the time of PCOS diagnosis. Screening for type 2 diabetes can be completed at the time of PCOS diagnosis with either a 2-hour glucose tolerance test or if that is not feasible, a fasting glucose with a measurement of the glycated hemoglobin A1C concentration can be done instead. PCOS is not associated with increased risk of ovarian cancer, breast cancer, ulcerative colitis, or pelvic organ prolapse (Barbieri & Ehrmann, 2024a).

  1. Sleep apnea is common in women with PCOS. To determine whether further evaluation for sleep apnea is needed you need to find out if Maria has any signs or symptoms of sleep apnea. Which of the following questions will help determine if she has signs or symptoms of sleep apnea?
    1. Do either of your parents wear a CPAP or BiPAP mask for sleeping?
    2. Do you have difficulty falling or staying asleep?
    3. Has your dentist ever told you that you have large tonsils?
    4. Do you feel that you experience frequent daytime sleepiness or morning headaches?
Answer:

D. Feedback:

Symptoms of sleep apnea include snoring, gasping, choking, interruptions in breathing while sleeping, excessive daytime sleepiness, and morning headaches. Difficulty falling or staying asleep indicates insomnia. Although there may be hereditary components to sleep apnea, this is not well-established, so asking about family history would not help you determine if she needs additional screening. Similarly, although craniofacial and upper abnormalities, such as large tonsils or adenoids, are associated with increased risk of sleep apnea, the presence of these abnormalities alone is not an indication for sleep apnea screening and do not tell you if she has clinical signs or symptoms of the condition (Kline, 2024).

  1. The visit continues as you and Maria discuss the diagnosis of PCOS and make plans for the next steps. You observe that Maria is quietly tearful and seems withdrawn. This prompts you to do the following:
    1. Screen for depression and anxiety.
    2. Nothing is needed, her response is part of normal coping behavior after receiving a difficult diagnosis.
    3. Screen for bipolar disorder using the Rapid Mood Screener.
    4. Place a referral for cognitive behavioral therapy.
    5. Screen for alcohol use disorder because you are concerned that she may start drinking more alcohol to cope with the emotions surrounding this new diagnosis.
Answer:

A. Feedback:

Screening for depression and anxiety is recommended at the time of PCOS diagnosis because women with PCOS are at increased risk of having these conditions (Barbieri & Ehrmann, 2024a). The PHQ9 can be used to screen for depression and the GAD7 can be used to screen for depression (Bickley, 2024). Although her tearful response may very well be a normal emotional response to receiving a difficult diagnosis, she still requires screening for depression and anxiety because of the increased risk of these conditions in women with PCOS. There is no association between bipolar disorder and PCOS. At this time, there is no indication to refer for cognitive behavioral therapy. Alcohol use disorder is not associated with PCOS. Although it is recommended that all adult patients are screened for unhealthy alcohol use, this is not specifically related to PCOS and the priority is to screen for depression and anxiety.

Clinical Pearls

Key Features

  • Irregular menstrual cycles
  • Hirsutism
  • Polycystic ovarian morphology on transvaginal ultrasound (TVUS)

Diagnosis

  • Rotterdam criteria: 2 out of 3 of the following criteria are diagnostic of PCOS:
    • Oligo- and/or anovulation
    • Clinical and/or biochemical signs of hyperandrogenism
    • Polycystic ovaries by ultrasound
  • In many cases, women with irregular menstrual cycles and hyperandrogenic symptoms can be diagnosed based on history and physical alone. However, other conditions that cause oligo/amenorrhea and hyperandrogenism must be ruled out. Conditions that mimic PCOS by causing oligo/amenorrhea and hyperandrogenism include:
    • Thyroid disease
    • Nonclassic congenital adrenal hyperplasia
    • Androgen secreting tumors
  • Once the diagnosis of PCOS is made, women should be evaluated for the following conditions, which are associated with PCOS:
    • Mood disorders
    • Fatty liver
    • Obstructive sleep apnea
    • Cardiometabolic risk
    • Infertility for patients who are pursuing fertility
