Preterm labor biomarker discovery in serum using 3 proteomic profiling methodologies.

Objective: The aim of this study was to identify changes in protein expression in normal pregnancy compared with preterm labor by using 3 proteomic methods.

Study Design: Serum was collected from 25 nonpregnant (n = 5) and pregnant women at 24-40 weeks' gestation (n = 20) who had preterm labor resulting in preterm delivery (n = 5), preterm labor with term delivery (n = 5), term labor resulting in delivery (n = 5), or at term with contractions (n = 5). Undepleted serum was used for surface-enhanced laser desorption ionization and immune-depleted serum for matrix-assisted laser desorption ionization and 2-dimensional electrophoresis.

The diagnostic dilemma of thrombotic thrombocytopenic purpura/hemolytic uremic syndrome in the obstetric triage and emergency department: lessons from 4 tertiary hospitals.

Objective: We report a series of occurrences of thrombotic thrombocytopenic purpura (TTP)/hemolytic uremic syndrome (HUS) in pregnancy that emphasizes early diagnosis.

Study Design: Fourteen pregnancies with TTP (n = 12) or HUS (n = 2) were studied. Analysis focused on clinical and laboratory findings on examination, initial diagnosis, and treatment.

Diagnosis and management of atypical preeclampsia-eclampsia.

Preeclampsia, eclampsia, and hemolysis, elevated liver enzymes, and low platelets syndrome are major obstetric disorders that are associated with substantial maternal and perinatal morbidities. As a result, it is important that clinicians make timely and accurate diagnoses to prevent adverse maternal and perinatal outcomes associated with these syndromes. In general, most women will have a classic presentation of preeclampsia (hypertension and proteinuria) at > 20 weeks of gestation and/or < 48 hours after delivery.

The coexistence of gestational hypertension and diabetes: influence on pregnancy outcome.

Gestational hypertension (GHTN) and gestational diabetes mellitus (GDM) are both insulin resistance states. Perinatal outcome of GHTN or GDM alone are well established, but their combined effect on pregnancy outcome is underinvestigated. Our objective was to determine if pregnancies complicated by GHTN/GDM have higher rates of morbidity.

HELLP syndrome: an atypical presentation.

HELLP syndrome without proteinuria or hypertension is rare. We present the case of a 33-year-old primigravid who initially was diagnosed with pulmonary embolism. The patient was readmitted with a diagnosis of subcapsular hematoma and eventually diagnosed with HELLP syndrome with a sequela of hepatic rupture.

Postpartum headache: is your work-up complete?

Objective: Headache is a common finding in the postpartum period, and there are limited data describing the cause and treatment of women with postpartum headache. Our objective was to describe our experience with women who were hospitalized for postpartum headache and to develop a management algorithm for these women.

Study Design: Data for 95 women with headache >24 hours after delivery from 2000-2005 were reviewed retrospectively.

Thrombophilia and adverse maternal-perinatal outcome: controversies in screening and management.

A recent review of the literature on thrombophilia and adverse pregnancy outcome reveals contradictory findings. There are retrospective and prospective studies that recommend testing for genetic and acquired markers of thrombophilia for those with the enumerated adverse pregnancy outcome. Based on our review, routine screening for thrombophilias in women with a history of adverse pregnancy outcome (preeclampsia, abruptio placenta, intrauterine growth restriction, and fetal loss) is not justified.

Thrombophilia and adverse maternal-perinatal outcome.

A recent review of the literature on thrombophilia and adverse pregnancy outcome (APO) reveals contradictory findings. We have limited our review of literature mostly to the most recent decade. On the basis of our review, screening for thrombophilias with a history of APO (preeclampsia, abruptio placenta, intrauterine growth restriction, and fetal loss) is not clear.

Preeclampsia: Diagnosis and management of the atypical presentation.

Preeclampsia, eclampsia, and HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome remain as major obstetric problems that plague a large percentage of women resulting in an equally large percentage of maternal and perinatal morbidities. It is important that a clinician makes the most accurate diagnosis possible to prevent these adverse maternal and perinatal outcomes. In general, most women will have a classical presentation of preeclampsia (hypertension and proteinuria) at >20 weeks gestation and <48 hours postpartum.

Tocolysis in women with preterm labor between 32 0/7 and 34 6/7 weeks of gestation: a randomized controlled pilot study.

Objective: The purpose of this study was to determine whether intravenous magnesium sulfate (MgSO4) followed by oral nifidepine tocolysis in women with preterm labor between 32 0/7 and 34 6/7 weeks' gestation reduces neonatal hospital stay.

Study Design: Fifty-four women between 32 0/7 and 34 6/7 weeks with preterm labor were randomized to receive either MgSO4 and oral nifidepine (n = 24) or no tocolysis (n = 30). All women received betamethasone and prophylactic antibiotics.
