Question

Ms. O is a 28-year-old woman married for 3 years who has just returned from an outdoor camping trip with her husband, with symptoms of dysuria with a burning sensation, urgency to urinate, and frequent urination. She said, “I have had similar symptoms three times over the last 2 years. Pubic and low back discomfort awoke me two nights ago and that is why I am here.” On physical examination, her temperature was 98.6° F, blood pressure was 114/64 mm Hg, pulse was 68 beats per minute, and the respiratory rate was 12 breaths per minute. Other than a tender abdominal pelvic area, the examination was unremarkable.

Question #3 Notable laboratory results from a dipstick urinalysis, microscopic examination, and urine culture: Color was dark yellow; trace blood; no casts; bacteria, especially E. coli, and WBCs were too numerous to count.

Given the following laboratory results, what is her final diagnosis and treatment?

Explanation / Answer

The symptoms point towards Trichomoniasis which is sexually transmitted infection. It is caused due to Trichomonas vaginalis which is a flagellated protozoan parasite. Since the examination was unremarkable ordering a lab test on a sample of vaginal or urethral fluid to look for the disease-causing parasite is a good idea. Once the diagnosis is confirmed it is safe to move on to the treatment.

Treatment: The drug that is used for treating Trichomoniasis is an oral antibiotic- metronidazole (Flagyl). This is also the only safe drug is also given in case the patient is suspected to be pregnant. It is necessary that patient's sexual partner is also treated for the same to avoid further complications.
