Gynecologic Infections

A $24$-year-old nulligravid woman comes to the clinic due to worsening lower abdominal pain and a new, foul-smelling vaginal discharge over the past $4$ days. She has a copper intrauterine device (IUD) that was inserted three years ago. She recently became sexually active with a new male partner. Her temperature is $38.2^\circ\text{C}$ ($100.8^\circ\text{F}$), blood pressure is $118/76\text{ mm Hg}$, and pulse is $92\text{/min}$. Speculum examination shows a yellow, mucopurulent discharge exuding from the cervical os, and the IUD strings are clearly visible in the vaginal vault. Bimanual examination reveals pronounced cervical motion tenderness and bilateral adnexal tenderness. There are no palpable adnexal masses, and a pelvic ultrasound is unremarkable aside from a properly positioned intrauterine device. A urine pregnancy test is negative. Which of the following is the most appropriate next step in management?

Match each clinical presentation of a lower genital tract infection with the most appropriate corresponding microscopic or diagnostic laboratory finding.

A 29-year-old woman comes to the clinic reporting a bothersome, malodorous vaginal discharge for the past week. She describes the odor as "fishy" and notes that it becomes more pronounced after unprotected sexual intercourse. She has a new male sexual partner. The patient denies any vulvar itching, burning, dysuria, or lower abdominal pain. Her medical history is unremarkable, and she takes no medications. Vital signs are within normal limits. Pelvic examination reveals a thin, homogeneous, grayish-white discharge evenly coating the vaginal walls. There is no vulvovaginal erythema, cervical motion tenderness, or adnexal tenderness. The vaginal fluid pH is 5.5. Addition of 10% potassium hydroxide to the vaginal discharge produces a strong amine odor. Microscopic evaluation of a wet mount preparation reveals squamous epithelial cells whose borders are obscured by adherent coccobacilli. Which of the following is the most appropriate next step in management?

A series of afebrile patients with stable vital signs present to the gynecology clinic evaluating for abnormal vaginal discharge and discomfort. Match each patient's specific clinical context and diagnostic findings with the most accurate diagnosis and its corresponding guideline-concordant management.

A 23-year-old woman presents to the clinic with a 4-day history of a copious, malodorous vaginal discharge and mild vulvar itching. She is sexually active with a new male partner and uses oral contraceptive pills consistently. Her temperature is 37.1°C (98.8°F), blood pressure is 110/70 mmHg, and pulse is 76/min. Pelvic examination reveals a frothy, yellow-green discharge in the vaginal vault and punctate macular hemorrhages on the cervix. Vaginal pH is measured at 6.0. Wet mount microscopy demonstrates numerous motile, flagellated organisms slightly larger than polymorphonuclear leukocytes. Which of the following is the most appropriate pharmacotherapy for this patient?

Match the following gynecologic infections with their classic clinical and laboratory findings.

A 26-year-old woman evaluates at the urgent care center due to four days of copious, malodorous vaginal discharge associated with mild dysuria. Her medical history is unremarkable, and she recently became sexually active with a new male partner. Her temperature is $37.1^\circ\text{C}$ ($98.8^\circ\text{F}$). Speculum examination demonstrates frothy, yellow-green fluid pooled in the posterior vaginal fornix and several punctate macular hemorrhages on the cervix. A saline microscopy preparation of the fluid reveals multiple motile, pear-shaped, flagellated organisms slightly larger than polymorphonuclear leukocytes. Which of the following is the most appropriate pharmacological intervention?

Following a presentation of severe, bilateral lower pelvic pain and high-grade fever ($38.9^\circ\text{C}$), a $32$-year-old female is evaluated in the emergency department. She reports having a copper intrauterine device (IUD) inserted four years prior. On physical examination, marked cervical motion tenderness and purulent cervical exudate are noted. Pelvic ultrasonography confirms the IUD is properly situated within the endometrial cavity and reveals bilateral fallopian tube thickening consistent with severe pelvic inflammatory disease (PID), but no tubo-ovarian abscess is visualized. The patient is admitted to the inpatient ward for complicated PID.

Arrange the following diagnostic and therapeutic interventions in the most appropriate chronological sequence according to current clinical guidelines.

For each of the following complicated or atypical presentations of gynecologic infections, select the most appropriate evidence-based management strategy.

During a routine follow-up visit at the community health center, a 26-year-old G2P2 woman complains of deep pelvic pain with intercourse and a new-onset, foul-smelling vaginal discharge over the past week. Her medical history includes the insertion of a copper intrauterine device (IUD) 18 months ago. Vital signs are within normal limits except for a temperature of 38.1°C (100.6°F). On bimanual examination, there is marked tenderness upon moving the cervix and bilateral adnexal fullness with guarding, but no discrete mass is palpated. A point-of-care urine pregnancy test is negative. Which of the following is the most appropriate next step in the management of this patient's condition?

A 26-year-old woman, gravida 1 para 0, at 10 weeks gestation presents to the clinic for an initial prenatal visit. She reports feeling well, noting only mild morning nausea and bilateral breast tenderness. She describes a slight increase in clear vaginal discharge over the past few weeks but denies any pruritus, malodor, dyspareunia, or dysuria. Her temperature is 37.0°C (98.6°F), blood pressure is 112/72 mmHg, and heart rate is 78/min. Pelvic examination reveals a closed, nulliparous-appearing cervix without friability, erythema, or visible lesions. A small amount of clear, non-malodorous mucus is present in the vaginal vault. Bimanual examination shows a soft, appropriately enlarged uterus with no adnexal tenderness. Routine prenatal laboratory screening is performed. The cervical nucleic acid amplification test (NAAT) returns positive for *Chlamydia trachomatis* and negative for *Neisseria gonorrhoeae*. She has no known drug allergies. Which of the following is the most appropriate management for this patient?

A 19-year-old woman comes to the emergency department complaining of sudden-onset, sharp right upper quadrant abdominal pain that worsens with deep inspiration. She also reports a 5-day history of lower pelvic discomfort and spotting between her menstrual periods. She recently became sexually active with a new male partner. Her only medication is an oral contraceptive. Her temperature is 38.3°C (101.0°F), blood pressure is 112/68 mmHg, pulse is 98/min, and respirations are 18/min. Physical examination shows marked right upper quadrant tenderness without guarding or rebound. Murphy sign is negative. There is also bilateral lower quadrant tenderness. Pelvic examination reveals a mucopurulent cervical discharge and pronounced cervical motion tenderness.

Correlate each specific clinical scenario involving a gynecologic infection (or related incidental finding) with its most appropriate, guideline-concordant next step in management.

A 24-year-old nulligravid woman is evaluated in the hospital on the third day of admission for pelvic inflammatory disease complicated by a 4-cm left tubo-ovarian abscess. On admission, she presented with a temperature of 38.9°C (102.0°F), severe lower abdominal pain, and a leukocyte count of 18,500/mm³. She was started on intravenous cefoxitin and oral doxycycline. Today, she reports feeling much better. Her temperature is 37.1°C (98.8°F), blood pressure is 118/76 mm Hg, pulse is 78/min, and respirations are 14/min. Abdominal examination shows significantly decreased tenderness with no rebound or guarding. Pelvic examination reveals markedly improved cervical motion tenderness and a stable left adnexal fullness. She is tolerating a regular diet, and her leukocyte count has decreased to 9,200/mm³. Which of the following is the most appropriate next step in management?

Review the following microscopic descriptions of vaginal secretions prepared with normal saline or potassium hydroxide. Associate each distinct microscopic finding with the most likely corresponding gynecologic infection.

A 24-year-old woman comes to the clinic for a follow-up visit regarding persistent vaginal discharge and spotting after intercourse. Three weeks ago, she presented with similar symptoms and was diagnosed with cervicitis. A nucleic acid amplification test (NAAT) at that time was positive for *Chlamydia trachomatis* and negative for *Neisseria gonorrhoeae*. She was prescribed a 7-day course of oral doxycycline, which she completed. Her new male sexual partner was also treated, and they abstained from sexual activity for 10 days. Today, her vital signs are within normal limits. Pelvic examination reveals an erythematous, friable cervix with mucopurulent discharge. No cervical motion tenderness or adnexal tenderness is appreciated. A repeat NAAT for *C. trachomatis* and *N. gonorrhoeae* is negative. Wet mount microscopy shows numerous polymorphonuclear leukocytes but no clue cells, trichomonads, or pseudohyphae. Which of the following is the most appropriate next step in management?

A 22-year-old female is evaluated in the emergency department for three days of worsening right-sided abdominal pain and lower pelvic discomfort. The abdominal pain is sharp, exacerbated by deep inspiration, and accompanied by nausea. She has a past medical history of asthma and a severe allergic reaction to amoxicillin during childhood that resulted in anaphylaxis and endotracheal intubation. Her temperature is 38.9°C (102.0°F), blood pressure is 112/72 mmHg, and pulse is 114/min. Physical examination reveals right upper quadrant tenderness with a palpable friction rub over the anterior costal margin, as well as profound bilateral lower abdominal tenderness. Pelvic examination demonstrates a friable cervix with mucopurulent discharge at the cervical os and exquisite pain on cervical motion. Laboratory studies show a leukocyte count of 16,800/mm³. Liver aminotransferases and alkaline phosphatase levels are within normal limits. A right upper quadrant ultrasound demonstrates no biliary abnormalities and no pericholecystic fluid. Which of the following is the most appropriate initial pharmacologic management for this patient?

A 25-year-old woman is evaluated in the emergency department for severe bilateral lower quadrant abdominal pain, intractable nausea, and a fever of $39.1^{\circ}\text{C}$ ($102.4^{\circ}\text{F}$). She is unable to tolerate oral fluids. On pelvic examination, there is severe cervical motion tenderness and a palpable left adnexal fullness. Arrange the following steps in the correct chronological sequence for the standard diagnostic workup and management escalation of this patient's suspected complicated Pelvic Inflammatory Disease (PID).

A 25-year-old woman presents to the ambulatory care clinic with complaints of increased, yellowish vaginal discharge for the past week. She denies any pelvic pain, fever, nausea, or burning with urination. The patient is sexually active with a new male partner and reports inconsistent use of barrier contraception. Her medical history is unremarkable, and she takes only a daily oral contraceptive pill. Vital signs show a temperature of 37.1°C (98.8°F), blood pressure of 118/76 mmHg, and a heart rate of 78/min. On pelvic examination, the vagina appears normal, but the cervix is erythematous, edematous, and bleeds easily upon speculum contact. A sample of mucopurulent discharge is visible at the cervical os. Bimanual examination demonstrates a normal-sized, non-tender uterus and no adnexal masses or cervical motion tenderness. A rapid nucleic acid amplification test (NAAT) performed in the clinic on a cervical swab returns positive for *Neisseria gonorrhoeae* and negative for *Chlamydia trachomatis*.
