Match the following classic infectious disease clinical presentations with their most appropriate first-line antimicrobial therapy.
- A 22-year-old non-pregnant woman with acute onset of dysuria, increased urinary frequency, and suprapubic tenderness; she is afebrile with no flank pain.Oral nitrofurantoin
- A 35-year-old man presenting with a single, painless, well-circumscribed, indurated genital ulcer and bilateral non-tender inguinal lymphadenopathy.Intramuscular penicillin G benzathine
- A 40-year-old man from Connecticut presenting in July with a target-shaped erythematous rash (erythema migrans) on his thigh and mild fatigue.Oral doxycycline
- A 28-year-old woman with a thin, grayish-white vaginal discharge that has a prominent 'fishy' odor, particularly noticeable after intercourse.Oral metronidazole
Cevap
The correct matches align each classic clinical presentation with its standard, guideline-directed first-line antimicrobial agent: Uncomplicated cystitis with Oral nitrofurantoin, Primary syphilis with Intramuscular penicillin G benzathine, Early localized Lyme disease with Oral doxycycline, and Bacterial vaginosis with Oral metronidazole.
Each presentation represents a highly classic clinical scenario with a strongly established first-line treatment. Uncomplicated cystitis requires medications that concentrate well in the lower urinary tract (nitrofurantoin). Treponema pallidum remains highly susceptible to penicillin. Borrelia burgdorferi is covered excellently by doxycycline. Gardnerella and other anaerobes in bacterial vaginosis respond well to metronidazole.
