Neonatal ovarian cysts.

UNLABELLED: Foetal and neonatal ovarian cysts have previously been considered uncommon. With the development of sonography, however, the detection of cysts has increased. As ovarian cyst formation in the perinatal period is a self-limiting process, treatment options depend on the risk of complications and on the ability to differentiate these benign cysts from other pathology. The history of two neonates with an ovarian cyst detected antenatally with ultrasound techniques is described. CONCLUSION: It is important that paediatricians have knowledge about the incidence, treatment and prognosis of foetal neonatal ovarian cysts.

Heparin-induced thrombocytopenia is rare in pregnancy.

OBJECTIVE: The indications for heparin use during pregnancy are expanding; however, heparin is associated with serious adverse effects including heparin-induced thrombocytopenia. Low-molecular-weight heparin is expensive but is associated with less frequent occurrences of heparin-induced thrombocytopenia in the nonpregnant population. However, the incidence of heparin-induced thrombocytopenia during pregnancy is unknown. The purpose of this study was to compare the incidence of heparin-induced thrombocytopenia in pregnant and nonpregnant women. STUDY DESIGN: This is a retrospective cohort comparison. Pregnant and nonpregnant women were identified by means of diagnosis related group and Current Procedural Terminology code searches at three medical centers in Utah; the incidence of heparin-induced thrombocytopenia in the two groups was compared. RESULTS: There were 10 (4%) cases of thrombocytopenia among 244 heparin-treated pregnant patients and 26 (11%) cases among the 244 nonpregnant controls. There were no cases of heparin-induced thrombocytopenia in the pregnant group, but there were 10 (4%) cases in the control group (P =.0014). CONCLUSION: Heparin-induced thrombocytopenia is extremely rare in pregnant women.
