    Title Erp Implementation in Rural Health Care.
    Date September 2002
    Journal Journal of Management in Medicine
    Excerpt

    Enterprise resource planning (ERP) systems provide organizations with the opportunity to integrate individual, functionally-oriented information systems. Although much of the focus in the popular press has been placed on ERP systems in large for-profit organizations, small hospitals and clinics are candidates for ERP systems. Focusing information systems on critical success factors (CSFs) allows the organization to address a limited number of areas associated with performance. This limited number of factors can provide management with an insight into dimensions of information that must be addressed by a system. Focuses on CSFs for small health-care organizations. In addition, also considers factors critical to the implementation of health-care information systems. Presents two cases. The results indicate support for the continuing use of CSFs to help focus on the benefits of ERPs. Focusing on groups of tangible and intangible benefits can also assist the rural health-care organization in the use of ERPs.

    Title Prenatal Diagnosis of the Klippel-trenaunay-weber Syndrome.
    Date April 1995
    Journal Prenatal Diagnosis
    Excerpt

    The Klippel-Trenaunay-Weber syndrome is a complex developmental disorder of the vascular and skeletal systems. While many features of the syndrome are congenital, it has not been diagnosed often before birth. This paper describes a case of Klippel-Trenaunay-Weber syndrome diagnosed at 19 weeks' gestation on the basis of sonographic findings and family history. The clinical variability of the syndrome is emphasized and the importance of family history in differential diagnosis is stressed.

    Title Antibiotic Concentration in Maternal Blood, Cord Blood and Placental Tissue in Women with Chorioamnionitis.
    Date July 1992
    Journal Gynecologic and Obstetric Investigation
    Title "meconiumcrit" and Birth Asphyxia.
    Date December 1991
    Journal American Journal of Obstetrics and Gynecology
    Excerpt

    Determination of the percent by volume of the solid component of meconium (the "meconiumcrit") provides a more objective method of characterizing the type of meconium. In a study of 106 women with meconium-stained amniotic fluid, 61 (58%) had thin meconium, 36 (34%) had moderate meconium, and nine (8%) had thick meconium. There was no correlation between the type of meconium and newborn acidemia (umbilical artery pH, less than 7.20)--13%, 19%, and 11%, respectively. None of the newborns with either thin or thick meconium had 1-minute Apgar scores of less than or equal to 3 and only two with moderate meconium had such Apgar scores; none had an Apgar score of less than or equal to 3 at 5 minutes. None of the newborns with thin or moderate meconium had meconium aspiration syndrome, although two of nine infants with thick meconium did have meconium aspiration syndrome. All newborns subsequently did well and left the hospital in good condition. There would appear to be no correlation between the consistency of meconium and recently reported criteria for defining birth asphyxia.

    Title Observations on the Cause of Oligohydramnios in Prolonged Pregnancy.
    Date January 1991
    Journal American Journal of Obstetrics and Gynecology
    Excerpt

    There is increasing evidence that implicates reduced amnionic fluid volume as a major determinant of fetal risk in prolonged pregnancy. We sought to determine whether reduced fetal urine production might be associated with oligohydramnios in pregnancies that reach 42 weeks or more. Ultrasonographic measurements of the fetal bladder were obtained every 2 to 5 minutes for 1 hour in 38 gestations verified to be at least 42 weeks. Oligohydramnios was present in eight of the prolonged pregnancies. Similar measurements were performed in 15 normal pregnancies delivered by elective repeat cesarean section between 38 and 40 weeks' gestation. Hourly fetal urine production rates were calculated with sequential bladder volume measurements. The result of this investigation suggest that diminished fetal urine production is associated with oligohydramnios in prolonged pregnancy. The mechanism by which fetal urine production is reduced in prolonged pregnancy remains unknown. A likely possibility is reduced fetal swallowing because of already diminished amnionic fluid volume, the latter a result of placental senescence.

    Title Peripartum Cocaine Use and Adverse Pregnancy Outcome.
    Date
    Journal American Journal of Human Biology : the Official Journal of the Human Biology Council
    Excerpt

    The objective of the study was to analyze possible adverse effects of peripartum cocaine use on maternal and fetal outcomes. Informed consent was given by 720 (97%) of 740 women who delivered consecutively at a large urban public hospital to test an umbilical cord blood sample for the presence of non-medically administered drugs of abuse and alcohol and to be interviewed for the study. Samples were tested for the presence of a cocaine metabolite (benzoylecgonine-BZE) by radioimmunoassay. The presence of other substances of abuse (alcohol, methamphetamine, opiates) resulted in exclusion from the sample of 143 subjects. Thus, in this cohort analysis, drug-free controls (N = 469) were compared to those positive for cocaine only (N = 108). Peripartum exposure to cocaine only, and no other substances of abuse, was associated with an increased frequency of abruptio placentae (1.9% vs 0% for control, P < 0.004), thick meconium stained amniotic fluid (3.9% vs 0.7% for controls, P < 0.006), premature rupture of membranes (P < 0.02), genitourinary anomalies (OR = 3.6, P < 0.05), abdominal wall defects (OR = 4.4, P < 0.01) and increased frequency of low birth weight (OR = 2.0, P < 0.02). These are important findings because previous studies have been complicated by the confounding effects of other substances of abuse. Am. J. Hum. Biol. 11:598-602, 1999.
