Induction of labor is a common obstetric procedure, and approximately one-fourth of pregnant patients undergo the procedure. Although exercise and nipple stimulation can increase the likelihood of spontaneous labor, sexual intercourse may not be effective. Acupuncture has been used for labor induction; however, it has not been shown to increase vaginal delivery rates. ⋯ The effect of amniotomy on labor is uncertain. Pharmacologic intervention with oxytocin or prostaglandins is effective for cervical ripening and induction of labor. Combining a balloon catheter with misoprostol is a common practice and has been shown to decrease time to delivery in a small study.

Fever of unknown origin is defined as a clinically documented temperature of 101°F or higher on several occasions, coupled with an unrevealing diagnostic workup. The differential diagnosis is broad but is typically categorized as infection, malignancy, noninfectious inflammatory disease, or miscellaneous. Most cases in adults occur because of uncommon presentations of common diseases, and up to 75% of cases will resolve spontaneously without reaching a definitive diagnosis. ⋯ If noninvasive diagnostic tests are unrevealing, then the invasive test of choice is a tissue biopsy because of the relatively high diagnostic yield. Depending on clinical indications, this may include liver, lymph node, temporal artery, skin, skin-muscle, or bone marrow biopsy. Empiric antimicrobial therapy has not been shown to be effective in the treatment of fever of unknown origin and therefore should be avoided except in patients who are neutropenic, immunocompromised, or critically ill.
