ReviewLong-term consequences of the posterior reversible encephalopathy syndrome in eclampsia and preeclampsia: a review of the obstetric and nonobstetric literature.
This review summarizes the long-term consequences of the posterior reversible encephalopathy syndrome (PRES) that have been described in the obstetric literature (eclampsia and preeclampsia) and compares these with data from the nonobstetric literature. Preeclampsia is characterized by new-onset hypertension and proteinuria after the 20th week of pregnancy. Neurological symptoms include headache; visual deficits; confusion; seizures; and, in the most severe cases, intracranial hemorrhage. ⋯ Although no firm conclusions can be drawn because of the heterogeneity of reported cases, some general comments can be made. Because most persistent long-term problems are present in the nonobstetric population, the main determinant for these long-term problems may be the underlying condition that gave rise to the PRES episode. In addition, most reports suggest that late diagnosis or inadequate therapy may contribute, emphasizing the need for early recognition, adequate treatment, follow-up, and support.

In utero fetal surgery interventions are currently considered in selected cases of congenital diaphragmatic hernia, cystic pulmonary abnormalities, amniotic band sequence, selected congenital heart abnormalities, myelomeningocele, sacrococcygeal teratoma, obstructive uropathy, and complications of twin pregnancy. Randomized controlled trials have demonstrated an advantage for open fetal surgery of myelomeningocele and for fetoscopic selective laser coagulation of placental vessels in twin-to-twin transfusion syndrome. The evidence for other fetal surgery interventions, such as tracheal occlusion in congenital diaphragmatic hernia, excision of lung lesions, fetal balloon cardiac valvuloplasty, and vesicoamniotic shunting for obstructive uropathy, is more limited. ⋯ Moreover, there is scanty information on long-term outcomes. It is recommended that fetal surgery procedures be performed in centers with extensive facilities and expertise. The aims of this review were to describe the main fetal surgery procedures and their evidence-based results and to provide generalist obstetricians with an overview of current indications for fetal surgery.

ReviewFetal endoscopic tracheal occlusion for congenital diaphragmatic hernia: indications, outcomes, and future directions.
In the present study, we review the indications, technical aspects, preliminary results, risks, and clinical implications of fetal endoscopic tracheal occlusion (FETO) for severe congenital diaphragmatic hernia (CDH) performed outside the United States and its potential future directions in this country and globally. Congenital diaphragmatic hernia occurs in approximately 1 in 2500 live births and results in high neonatal morbidity and mortality, largely associated with the severity of pulmonary hypoplasia and pulmonary arterial hypertension. With the advent of prenatal imaging, CDH can be diagnosed before birth, and in utero treatment is now available in some centers. ⋯ Fetal endoscopic tracheal occlusion is thought to improve outcomes by decreasing mortality and allowing more rapid neonatal stabilization. Ultimately, the goal of FETO is to minimize pulmonary hypoplasia and pulmonary arterial hypertension. Following delivery, neonates still require diaphragm repair.

Noninvasive prenatal testing (NIPT) refers to recently developed genetic tests of the maternal serum that allow higher detection rates of trisomy 21 and other chromosomal aneuploidies in high-risk pregnancies. Noninvasive prenatal test analyzes cell-free DNA (cfDNA) in the maternal serum. Approximately 3% to 15% of cfDNA in the maternal blood is of fetal origin. ⋯ Noninvasive prenatal test is a screening test, and both false-positive (0.2%-1%) and false-negative results can occur. As the technology for NIPT is further evaluated, this test is likely to be increasingly used for prenatal screening. This review provides the obstetric clinician with an update of the current issues concerning NIPT.

Effective postoperative pain management provides improved patient comfort and satisfaction, earlier mobilization, fewer pulmonary and cardiac complications, reduced risk of deep vein thrombosis, faster recovery, and reduced cost of care. Although many therapeutic modalities are available for pain management, the optimal combination in managing postoperative pain in total abdominal hysterectomy is controversial. The objective of this study was to review the literature to formulate optimal, evidence-based preoperative, intraoperative, and postoperative pain management for women undergoing total abdominal hysterectomy. Using the OVID platform, we searched in MEDLINE and PubMed using MeSH terms postoperative pain and total abdominal hysterectomy for published articles from 1960 to the present; we found 545 studies. We screened and included only randomized clinical trials, publications in English, human studies, and abdominal hysterectomy for noncancerous indications. We excluded 456 studies that reported on animal studies; laparoscopic, vaginal, supracervical, or robotic hysterectomy; pharmacokinetic studies; primary outcome other than pain management; and chronic pain management. Studies with inadequate power, poor methodology, or inconclusive results were further excluded from this review. Thus, 89 studies constituted the cohort for our article. Pain control remains complex given variables such as age, anxiety, and extent of surgery. In general, regimens should be tailored to the needs of the individual patient, taking into account medical, psychological, and physical condition. A multimodality approach is better than conventional, single-agent narcotic in achieving optimal pain management. After reading this article, the reader should be able to understand various modalities that can be considered for preoperative, intraoperative, and postoperative pain management in total abdominal hysterectomy. ⋯ Obstetricians and gynecologists, family physicians Learning Objectives: After completing this CME activity, physicians should be better able to understand various modalities that can be considered for preoperative, intraoperative, and postoperative pain management in total abdominal hysterectomy.
