Obstetrician-gynecologists performing genetic amniocentesis may be misleading themselves and their patients.

OBJECTIVE: Our purpose was to compare midtrimester amniocentesis-related fetal loss rates between obstetrician-gynecologists and perinatologists. STUDY DESIGN: This cohort study analyzes 1384 midtrimester amniocenteses from January 1, 1996, to December 31, 1999. Obstetrician-gynecologists who split their practices between two or more hospitals and explained fetal losses (eg, fetal anomalies, aneuploidy) were excluded from analysis. Eight obstetrician-gynecologists performed 138 procedures; 3 perinatologists performed 1246 procedures. Three experienced obstetrician-gynecologists accounted for 113 procedures. Analysis was by chi2. RESULTS: Within 30 days of midtrimester amniocentesis, there were 3 fetal losses for obstetrician-gynecologists and 4 for perinatologists (P =.02, chi2 = 5.19, degrees of freedom = 1). Obstetrician-gynecologist loss rates were 1 in 46 procedures versus 1 in 312 procedures for perinatologists. Losses were clustered among the 3 experienced obstetrician-gynecologists (P <.01, chi2 = 6.93, degrees of freedom = 1). The experienced obstetrician-gynecologist fetal loss rate was 1 in 38 amniocenteses, and the perinatologist fetal loss rate was 1 in 312. CONCLUSION: The risk of fetal loss from midtrimester amniocentesis appears to be higher when performed by an obstetrician-gynecologist compared with a perinatologist.

Use of two Greenfield caval filters to prevent recurrent pulmonary embolism in a heparin-allergic gravida.

BACKGROUND: Maternal mortality may be reduced by prompt diagnosis and treatment of pulmonary embolism. CASE: A 25-year-old pregnant woman required a second Greenfield filter after developing a heparin allergy and recurrent pulmonary embolism. CONCLUSION: Heparin allergy has not been reported previously in pregnancy. A Greenfield filter may be used in this circumstance. Extension of the thrombus cephalad to the filter can cause recurrent emboli, so deployment of a second caval filter may be an effective remedy.

Acute iron intoxication in pregnancy: case report and review of the literature.

Limited reports exist regarding acute iron intoxication during pregnancy. The maternal and fetal effects of accidental or deliberate ingestion of large amounts of iron may be catastrophic. A case report of acute iron intoxication, management strategies, and a review of the literature are presented. The cornerstones of effective therapy are aggressive management with emesis induction or gastric lavage, bicarbonate instillation, vigorous intravenous hydration, and chelation therapy with deferoxamine.
