The perinatal autopsy is an important tool in the investigation of fetal and neonatal death, and a complete understanding of its risks and benefits is necessary for providers of perinatal care. This review, from the perspective of a perinatal pathologist, reports the details of the autopsy procedure, its goals, its value to individual patients and the health care system in general, and its alternatives. Even with new emerging technologies, the conventional perinatal autopsy remains the gold standard for determining the cause of death and the final summary of all pathologic findings. Therefore, the information provided in this review can help providers properly convey information about perinatal autopsy to bereaved families.

ReviewAntenatal corticosteroid therapy: current strategies and identifying mediators and markers for response.
Landmark early work has led to the nearly universal use of antenatal corticosteroids to accelerate fetal lung maturity with pregnancies complicated by impending preterm birth. Antenatal corticosteroids clearly reduce respiratory morbidity, death, and other adverse neonatal outcomes. ⋯ This review article summarizes the history, clinical use, and pharmacology of antenatal steroids. In addition, the review highlights some potential mediators of steroid response and current research strategies aimed at possible optimization of this therapy.

ReviewThe outpatient management and special considerations of nausea and vomiting in pregnancy.
With 50-90% of pregnant women experiencing nausea and vomiting of pregnancy (NVP), the burden of illness can become quite significant if symptoms are under-treated and/or under-diagnosed, thus allowing for progression of the disease. The majority of these women will necessitate at least one visit with a provider to specifically address NVP, and up to 10% or greater will require pharmacotherapy after failure of conservative measures to adequately control symptoms. As a result, initiation of prompt and effective treatment in the outpatient setting is ideal. ⋯ Of note, co-existing gastroesophageal reflux disease (GERD), Helicobacter pylori infection, and psychosocial factors may have a negative impact on the management of NVP. Ultimately, every woman has her own perception of disease severity and desire for treatment. It is critical that both the provider and patient be proactive in the diagnosis and management of NVP.

ReviewGestational diabetes mellitus management with oral hypoglycemic agents.
Oral hypoglycemic agents such as glyburide (second-generation sulfonylurea) and metformin (biguanide) are attractive alternatives to insulin due to lower cost, ease of administration, and better patient adherence. The majority of evidence from retrospective and prospective studies suggests comparable efficacy and safety of oral hypoglycemic agents such as glyburide and metformin as compared to insulin when used in the treatment of women with gestational diabetes mellitus (GDM). ⋯ Additional research is needed to evaluate optimal dosage for glyburide and metformin during pregnancy. Comparative studies evaluating the effects of glyburide and metformin on long-term maternal and fetal outcomes are also needed.

ReviewAnesthesia implications of coagulation and anticoagulation during pregnancy.
Coagulation is an organized and well-orchestrated process that depends on the intrinsic balance between procoagulants, anticoagulants, and fibrinolytic systems. During pregnancy, this balance is affected in various ways and becomes more critical due to the physiologic changes and obligate hemorrhage after delivery. In some instances, this equilibrium will be disrupted. In this article, we describe the anesthetic implications of bleeding disorders, thrombophilias, and anticoagulation for the safe management of the parturient, with an emphasis on how this impacts decision-making by the anesthesiologist.
