Perinatal Management Of Women With Immune Thrombocytopenic Purpura: Survey Of United States Perinatologists, D. Peleg, Stephen Hunter

Stephen K. Hunter

OBJECTIVE: The aim of the study was to determine how perinatologists in the United States manage the care of women with immune thrombocytopenic purpura with respect to mode of delivery. Study Design: US members of the Society of Perinatal Obstetricians were surveyed with a 4-question questionnaire. Two mailings were sent. Questions 1 and 2 asked for a response regarding the perinatal management of delivery for women with chronic immune thrombocytopenic purpura and new-onset disease. The options were cordocentesis or fetal scalp blood sampling and cesarean delivery if the platelet count was <50,000 cells/microL, cesarean delivery if the maternal platelet count …

Periodontal Disease In Pregnancy Complicated By Type 1 Diabetes Mellitus, J. Guthmiller, J. Hassebroek-Johnson, D. Weenig, G. Johnson, H. Kirchner, F. Kohout, Stephen Hunter

BACKGROUND: Systemic disease and hormonal changes have been implicated as complicating factors for periodontal disease. Diabetes has been identified as a risk factor for periodontal disease, and diabetics can experience periodontal destruction at an earlier age than non-diabetic individuals. Increased hormone levels during pregnancy can contribute to increased gingival inflammation. The purpose of this study was to examine the association of type 1 diabetes mellitus (DM) on the periodontal status of pregnant women. METHODS: Thirty-three (13 diabetic and 20 non-diabetic) subjects, 20 to 39 weeks gestation, participated in this study. The mean age of the diabetics and non-diabetics was 28.5 …

Cell Encapsulation As A Potential Nondietary Therapy For Maternal Phenylketonuria., Donna Santillan, Mark Santillan, Stephen Hunter

OBJECTIVE: The objective of this work was to determine whether cells overexpressing phenylalanine (Phe) hydroxylase (PAH) can significantly reduce Phe in vitro for potential use as a therapy for preventing maternal phenylketonuria.

STUDY DESIGN: Human 293T and WRL68 cell lines were transiently and stably transfected to overexpress PAH. Cells were encapsulated within microspheres of sodium alginate. Timed measurements of Phe in media were performed using tandem mass spectrometry.

RESULTS: Both nonencapsulated and encapsulated transiently transfected cells overexpressing PAH significantly reduced the Phe concentration in media by approximately 50% in comparison to mock-transfected cells. Cell line clones stably expressing PAH significantly …

Leukemia In Pregnancy And Fetal Response To Multiagent Chemotherapy, W. Hansen, P. Fretz, Stephen Hunter, J. Yankowitz

Stephen K. Hunter

BACKGROUND: Leukemia is rare in pregnancy and treatment with intensive, multiagent chemotherapy produces complete remission in most adults, but might have deleterious effects on fetuses. CASE: A 24-year-old gravida 3 para 2 presented at 24 weeks with pruritus, rash, pancytopenia, and hepatitis. A bone marrow biopsy found acute lymphocytic leukemia. She completed three cycles of intensive multiagent chemotherapy with transient oligohydramnios in each cycle. Although there was decreased fetal growth rate, umbilical artery Doppler scans were normal. She delivered a normal 2150-g male infant at 36 weeks. CONCLUSION: Pregnant women with newly diagnosed leukemia should not delay treatment, but multiagent …
