Placental Chorioangioma with Nonimmune Hydrops Fetalis.

A 38-year-old woman was found to have a large placental chorioangioma. The fetus was studied using ultrasound. The pregnancy became complicated by hydrops fetalis, polyhydramnios, and abruptio placenta. The infant delivered at 29 weeks' gestational age. The neonatal course was complicated by nonimmune hydrops fetalis, respiratory distress syndrome, anemia, pulmonary hemorrhage, intraventricular hemorrhage, necrotizing enterocolitis, and bronchopulmonary dysplasia. The infant was discharged home with breastfeeding and off oxygen at 50 days of life. This case represents the multidisciplinary approach to the pregnancy complicated by a large placental chorioangioma and the resulting premature neonate with nonimmune hydrops fetalis.

Graves' Disease Pharmacotherapy in Women of Reproductive Age.

Graves' disease is an autoimmune disorder in which inappropriate stimulation of the thyroid gland results in unregulated secretion of thyroid hormones resulting in hyperthyroidism. Graves' disease is the most common cause of autoimmune hyperthyroidism during pregnancy. Treatment options for Graves' disease include thioamide therapy, partial or total thyroidectomy, and radioactive iodine. In this article, we review guideline recommendations for Graves' disease treatment in women of reproductive age including the recent guideline from the American College of Obstetricians and Gynecologists. Controversy regarding appropriate thioamide therapy before, during, and after pregnancy is reviewed. Surgical and radioactive iodine therapy considerations in this patient population are also reviewed. In patients who may find themselves pregnant during therapy or develop Graves' disease during their pregnancy, consideration should be given to the most appropriate treatment course for the mother and fetus. Thioamide therapy should be used with either propylthiouracil or methimazole at appropriate doses that target the upper range of normal to slightly hyperthyroid to avoid creating hypothyroidism in the fetus. Consideration should also be given to the adverse effects of thioamide, such as agranulocytosis and hepatotoxicity, with appropriate patient consultation regarding signs and symptoms. Individuals who wish to breastfeed their infants while taking thioamide should receive the lowest effective dose. Surgery should be reserved for extreme cases and limited to the second trimester, if possible. Radioactive iodine therapy may be used in nonpregnant individuals, with limited harm to future fertility. Radioactive iodine therapy should be withheld in pregnant women and those who are actively breastfeeding. Clinicians should keep abreast of developments in clinical trials and evidence-based recommendations regarding Graves' disease in reproductive-age women for any changes in evidence-based practice.

Outcomes of pregnancies at risk for hypertensive complications managed using impedance cardiography.

We assessed the effect of antihypertensive therapy guided by impedance cardiography on maternal and fetal outcomes in pregnancies at risk for hypertensive complications. We performed a retrospective review of the outcomes of 318 singleton pregnancies with chronic hypertension or prior preterm delivery due to preeclampsia whose antihypertensive therapy was guided by impedance cardiography. Hemodynamic subsets were compared using analysis of variance. Impedance cardiography was used to evaluate cardiac output and total peripheral resistance starting at less than 24 weeks. All patients received atenolol; 24% required additional therapy with a vasodilator. The mean gestational age at delivery was 37 +/- 2 weeks. Preeclampsia developed in 14%. The incidence of birth weight less than the 10th percentile was 10%. There were no perinatal deaths, and 75% of the infants spent <3 days in the hospital. Hyperdynamic patients had less preeclampsia, less severe preeclampsia, fewer deliveries <34 weeks, and fewer neonatal intensive care unit days compared with those requiring a vasodilator. Antihypertensive therapy guided by hemodynamic information results in pregnancies delivering at or near term, little preeclampsia, and no increase in growth restriction. Hyperdynamic patients have better outcomes than patients with increased total peripheral resistance.

Serotyping group B streptococci in a small community hospital: an analysis of distribution and site of isolation.

OBJECTIVE: To determine the prevalence and site of isolation of different serotypes of group B streptococcus (GBS) colonization or infection at a small community hospital. METHODS: GBS isolates were obtained from a small community hospital and were then serotyped as la, Ib, II, III, IV, V or nontypeable. Hospital records were reviewed for patient sex, age and pregnancy status as well as the site of GBS isolation. RESULTS: GBS serotypes Ia, III and V were most common and accounted for over 60% of the total number of isolates. Serotype Ia was most prevalent in reproductive-age females, while serotypes V and III were most prevalent in non-reproductive-age females and males, respectively. Serotype la was most frequent in both pregnant and nonpregnant females. Serotype IV was more common in this study population than in those from other locations. CONCLUSIONS: The GBS serotype distribution in this small community did not differ significantly from distributions described in larger North American centers. A GBS vaccine designed against multiple serotypes would be protective for most of this population.
