BACKGROUND: Iron infusions have become increasingly common in the treatment of iron-deficiency anemia during pregnancy. Although iron infusions are generally well tolerated, adverse reactions have been reported. CASE: A pregnant patient was diagnosed with rhabdomyolysis after receiving a second dose of intravenous (IV) iron sucrose at 32 6/7 weeks of gestation. On admission to the hospital, creatine kinase was 2,437 units/L, sodium was 132 mEq/L, and potassium was 2.1 mEq/L. Intravenous fluids and electrolyte repletion were administered, with improvement of symptoms within 48 hours. Creatinine kinase normalized 1 week after hospital discharge. CONCLUSION: Rhabdomyolysis can be associated with IV iron infusion during pregnancy.

BACKGROUND: The Yaari Extractor is intended to wrap around and guide the fetal shoulder to facilitate vaginal delivery in cases of shoulder dystocia. INSTRUMENT: The Yaari Extractor is a single-use device for fetal shoulder extraction. The device consists of two curved, rigid plastic–coated metal arms with handles and an elastic engagement element that includes two hollow sleeves that cover the portion of the device that enters the vagina and contacts the fetus. EXPERIENCE: The device has been used in three cases of shoulder dystocia. In all three cases, the shoulder dystocia was resolved without the need for ancillary obstetric maneuvers, and there was no reported maternal or fetal injury. CONCLUSION: The Yaari Extractor is a novel technology that can be used to successfully resolve shoulder dystocia.

Under the direction of U.S. Northern Command for COVID-19 pandemic response efforts, approximately 500 Navy Reserve medical professionals were deployed to the New York City area from April to June 2020. Some of these providers were asked to serve in 11 overburdened local hospitals to augment clinic staffs that were exhausted from the battle against coronavirus. Two maternal/fetal medicine physicians were granted emergency clinical providers to assist in these efforts.

OBJECTIVES: To determine practice patterns for shoulder dystocia and concepts dealing with brachial plexus palsy. METHODS: An Internet-based 25-question survey was electronically disseminated to all current members of the Central Association of Obstetricians and Gynecologists. For those individuals who did not respond, an additional opportunity to complete the assessment was provided during the 2009 annual meeting. RESULTS: Of 429 Central Association of Obstetricians and Gynecologists members, 268 (62%) responded, with 192 (78%) filling out the survey online. Nearly 90% of those queried believed that shoulder dystocia was unpredictable and unpreventable. Thirty-seven percent felt that an elective cesarean delivery should be offered for an estimated fetal weight of 4,500 g among nondiabetics. Just 40% would have allowed a trial of labor with a documented history of shoulder dystocia. Slightly more than half answered that they never used either lateral or excessive traction and obstetrician–gynecologists were more likely than maternal–fetal medicine specialists to conclude that traction applied by the clinician doing the delivery was the cause of shoulder dystocia-related brachial plexus palsy (36% compared with 12%, P=.005). Maternal–fetal medicine specialists were more likely to believe that 40–50% of brachial plexus palsies occur without concomitant shoulder dystocia (21% compared with 9%, P=.015). CONCLUSION: Differences in practice patterns exist among with regard to management recommendations of the American College of Obstetricians and Gynecologists' Practice Bulletin on shoulder dystocia. LEVEL OF EVIDENCE: III

Adult granulosa cell tumor associated with antecedent use of tamoxifen as adjuvant hormonotherapy for breast cancer is rare. The pathogenesis of this occurrence remains difficult to explain. The estrogenic effect of tamoxifen can be one such explanation.

The exact role of the Zavanelli maneuver for the management of shoulder dystocia still remains to be defined. None of the previously reported cases in which the Zavanelli maneuver has been employed described impaction of posterior fetal arm. At 40 weeks' gestation, a nulliparous patient with gestational diabetes, who underwent vacuum delivery, delivered an infant with shoulder dystocia. McRoberts' maneuver, suprapubic pressure, midline episiotomy, and Woods' maneuver were all unsuccessful in alleviating the shoulder dystocia. The posterior fetal arm was noted to be persistently impacted, so the Zavanelli maneuver was used to deliver an unsuspected macrosomic (4215 g) infant. The newborn, at the age of 3 years, has a right Erb's palsy. The Zavanelli maneuver can be used to alleviate a posterior arm shoulder dystocia, though there may be concomitant neurological injury.
