Efficacy Of Screening For Gestational Diabetes, G. Marquette, V. Klein, Jennifer Niebyl May 2013

Efficacy Of Screening For Gestational Diabetes, G. Marquette, V. Klein, Jennifer Niebyl

Jennifer R Niebyl

A cost analysis of glucose screening was studied prospectively in 434 patients. All patients underwent a 50-gm oral glucose load followed by a 1-hour plasma glucose screen test at 28 weeks (+/- 2 weeks). Patients with a screen test greater than or equal to 130 mg/dl plasma glucose were further tested with an oral glucose tolerance test. Also, previously described clinical risk factors for diabetes were documented on all patients. A 3.3% prevalence of gestational diabetes was found in 178 patients with risk factors, compared with 2.4% of 256 patients without risk factors, not a significant difference. Ten of the …


Prevention Of Perinatal Transmission Of Hepatitis B Virus: The Sensitivity, Specificity, And Predictive Value Of The Recommended Screening Questions To Detect High-Risk Women In An Obstetric Population, G. Mcquillan, T. Townsend, C. Johannes, T. Dillard, R. Molteni, P. Ness, Jennifer Niebyl May 2013

Prevention Of Perinatal Transmission Of Hepatitis B Virus: The Sensitivity, Specificity, And Predictive Value Of The Recommended Screening Questions To Detect High-Risk Women In An Obstetric Population, G. Mcquillan, T. Townsend, C. Johannes, T. Dillard, R. Molteni, P. Ness, Jennifer Niebyl

Jennifer R Niebyl

The Advisory Committee on Immunization Practices recommends that all pregnant women be questioned concerning risk factors for hepatitis B virus infection and that those giving positive responses be serotested. The sensitivity, specificity, and predictive value of those recommended questions among 692 parturient women were determined. A total of 59 currently or previously infected women (hepatitis B surface antigen (HBsAg), antibody to hepatitis B surface antigen (anti-HBs), or antibody to hepatitis B core antigen (anti-HBc) seropositive) were compared with the 633 seronegative women. Among nonwhite women, the sensitivity of a positive response to any one of the recommended questions was 60%. …


Cost-Effective Criteria For Glucose Screening, G. Marquette, V. Klein, J. Repke, Jennifer Niebyl May 2013

Cost-Effective Criteria For Glucose Screening, G. Marquette, V. Klein, J. Repke, Jennifer Niebyl

Jennifer R Niebyl

To study cost-effective screening criteria for gestational diabetes, a prospective study of 1012 patients was completed. All patients underwent a glucose screen between 26 and 30 weeks of gestation, consisting of a 50-g oral glucose load followed by a one-hour plasma glucose determination. Patients with a glucose screen greater than or equal to 130 mg/dL were studied with a standard three-hour oral glucose tolerance test. The incidence of gestational diabetes was 2.4% (24 of 1012). Only one gestational diabetic was identified with a glucose screen below 150 mg/dL. Twenty-two of the 24 cases were at least 24 years old. Twenty-one …


Lack Of Maternal Metabolic, Endocrine, And Environmental Influences In The Etiology Of Cleft Lip With Or Without Cleft Palate, Jennifer Niebyl, D. Blake, L. Rocco, R. Baumgardner, E. Mellits May 2013

Lack Of Maternal Metabolic, Endocrine, And Environmental Influences In The Etiology Of Cleft Lip With Or Without Cleft Palate, Jennifer Niebyl, D. Blake, L. Rocco, R. Baumgardner, E. Mellits

Jennifer R Niebyl

We studied metabolic, endocrine, and environmental factors in 59 women who had delivered a child with cleft lip with or without cleft palate (CL +/- CP) and compared these values with those of 56 mothers of unaffected children. There was no significant difference between the two groups with respect to race, age, weight, height, education, parity, menstrual history, medical illnesses, or the use of contraceptives, tobacco, alcohol, or caffeine. All patients had a normal XX karyotype confirmed by the fluorescent banding technique. The two groups demonstrated no significant difference in test results of serum chemistries, glucose tolerance, serum or erythrocyte …


Clinical High-Risk Designation Does Not Predict Excess Fetal-Maternal Hemorrhage, P. Ness, M. Baldwin, Jennifer Niebyl May 2013

Clinical High-Risk Designation Does Not Predict Excess Fetal-Maternal Hemorrhage, P. Ness, M. Baldwin, Jennifer Niebyl

Jennifer R Niebyl

During a 5-year period, an enzyme-linked antiglobulin test was used to screen and quantitate fetal-maternal hemorrhage in 789 consecutive D-negative mothers who were delivered of D-positive babies. Six hundred seventy-two patients (85.2%) had no detectable fetal-maternal hemorrhage, and 117 patients (14.8%) had a detectable fetal-maternal hemorrhage. Eight of the 789 (1%) had a fetal-maternal hemorrhage greater than 30 ml and required more than one vial of Rh immune globulin. Two patients with fetal-maternal hemorrhage of 29 and 30 ml also received additional Rh immune globulin. Each case was reviewed for the presence of high-risk features that are thought to predict …


Multiple Pregnancy With Late Death Of One Fetus, P. Cherouny, I. Hoskins, T. Johnson, Jennifer Niebyl May 2013

Multiple Pregnancy With Late Death Of One Fetus, P. Cherouny, I. Hoskins, T. Johnson, Jennifer Niebyl

Jennifer R Niebyl

Twenty cases of fetal death complicating a multiple pregnancy after 20 weeks' gestation are reviewed. We evaluated gestational age at diagnosis and delivery (29.3 +/- 0.7 and 31.8 +/- 0.9 weeks, respectively), interval from diagnosis to delivery (2.6 +/- 0.6 weeks), and cause of fetal death as a group and by type of placentation (76.5% monochorionic). Eighty-five percent of the surviving fetuses were delivered preterm, and the four neonatal deaths were all due to extreme prematurity, with a mean (+/- SEM) birth weight of 794 +/- 237 g. Perinatal mortality was 585 per 1000, 450 for twin A and 750 …
