Ultrasound Is The Optimal Choice For Guidance In Difficult Hysteroscopy., J. Kresowik, Craig Syrop, Bradley Van Voorhis, Ginny Ryan

Bradley J Van Voorhis

OBJECTIVES: To compare costs and complications associated with ultrasound-guided hysteroscopy vs laparoscopy-guided hysteroscopy vs hysteroscopy alone for the surgical repair of intrauterine septa and synechiae. METHODS: This was a retrospective cohort study. Charts of all patients undergoing reparative surgery for intrauterine synechiae or uterine septa at our academic institution between 2000 and 2008 were reviewed. A total of 159 procedures were included in the study, categorized into concurrent laparoscopic guidance (n = 69), ultrasound guidance (n = 52) or no guidance (n = 38). Data regarding billing, surgical case logs and complications were collected for these procedures. Using these data, …

OBJECTIVE: To determine the cost-effectiveness of infertility treatments. DESIGN: Retrospective cohort study. SETTING: Academic medical center infertility practice. PATIENT(S): All patients treated for infertility in a 1-year time span. INTERVENTION(S): Intrauterine inseminations, clomiphene citrate and IUI (CC-IUI), hMG and IUI (hMG-IUI), assisted reproductive techniques (ART), and neosalpingostomy by laparotomy. MAIN OUTCOME MEASURE(S): All medical charges and pregnancy outcomes associated with the treatments were obtained. Cost-effectiveness ratios defined as cost per delivery were determined for each procedure. The effects of a woman's age and the number of spermatozoa inseminated on cost-effectiveness of the procedures was also determined. RESULT(S): Intrauterine inseminations, CC-IUI, …

BACKGROUND: Long-term follow-up studies of children conceived by IVF are limited. We examine academic performance on standardized tests [Iowa Tests of Basic Skills/Educational Development (ITBS/ITED)] of children conceived by IVF. METHODS: Parents of children 8-17 years of age at the onset of the study (March 2008) who were conceived by IVF at the University of Iowa Hospitals and Clinics and living in the state of Iowa were contacted by mail. Parents completed questionnaires on their child's health and education and parental education. ITBS/ITED scores from school grades 3-12 were obtained on IVF children and a group of anonymous children matched …

OBJECTIVE: To determine the risk of major birth defects in cohorts of children conceived through IVF or through IUI as compared with naturally conceived children. DESIGN: Retrospective cohort study. SETTING: Academic medical center. PATIENT(S): Children conceived by IVF or IUI at the University of Iowa from 1989 through 2002, compared with a matched cohort of naturally conceived children. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Outcome data were obtained from Iowa state birth and fetal death certificates and from the Iowa Birth Defects Registry. RESULT(S): Ninety of 1,462 IVF-conceived children (6.2%) and 17 of 343 IUI-conceived children (5.0%) had a major birth …
