what is the most common type of uti that affects women?

• acute bacterial cystitis
• pyelonephritis
• asymptomatic bacteriuria
• pyelitis

Explanation:

Question 19

Eflornithine, when applied topically for facial hirsutism, works by inhibiting ornithine decarboxylase, an enzyme involved in hair follicle cell division. This inhibition slows the rate of hair growth. Reducing androgen levels is not its mechanism (androgens are systemic or from other treatments), it doesn't target alopecia (hair loss, opposite of hirsutism), and it doesn't inhibit gonadotropin secretion (that's for hormonal regulation of gonads, not hair growth at follicles).

UTIs (urinary tract infections) in women most commonly affect the bladder (cystitis). Acute bacterial cystitis is the most frequent, as the female urethra is shorter, making bladder infections more common. Pyelonephritis is kidney infection (less common than cystitis), asymptomatic bacteriuria is bacteria in urine without symptoms (not the most common symptomatic UTI), and pyelitis is also a kidney - related infection, less common than cystitis in women.

Answer:

A. It slows the rate of hair growth.
