Tele-obstetric ultrasound: analysis of first-trimester ultrasound images transmitted in realtime

We evaluated the diagnostic quality of first-trimester ultrasound images transmitted in realtime using low-cost telecommunications. A prospective sample of fetal ultrasound images from 11 weeks to 13 weeks and six days of pregnancy was obtained from pregnant women over 18 years old. The examinations were transmitted in realtime to three independent examiners who carried out a qualitative assessment based on parameters established by the Fetal Medicine Foundation. All fetal structures could be viewed and the quality of images received by the examiners was considered normal. There were significant differences for crown-rump length and nuchal translucency in the transmitted images but the loss in definition was acceptable. Thus the quality of images transmitted via the Internet through the use of low-cost software appeared suitable for screening for chromosomal abnormalities in the first trimester of pregnancy.

The profile of women who have experienced cesarean section and obstetric care at a public maternity hospital in Ribeirao Preto

The present paper presents the social and obstetric profile of women undergoing cesarean childbirth at a public maternity hospital in the interior of Sao Paulo state. This is a quantitative, retrospective, descriptive study performed using documental research. The collected data refer to the period between July and December 2005, and between January and June 2006. A total of 670 records were reviewed. A 23% rate of cesarean births was identified at the institution studied during the aforementioned period. The studied population was characterized as having a low level of education, living in a common-law relationship, and not having a paid occupation. The main indications for cesarean sections were iterativity and acute fetal distress. The findings revealed an emphasis on obstetric nursing in the low-risk normal childbirth scenario, considering the non-interventionist character inherent to their education and training.

Novel ADAMTS13 mutations in an obstetric patient with upshaw-schulman syndrome

Upshaw-Schulman syndrome (USS) is a rarely reported congenital form of thrombotic thrombocytopenic purpura (TTP) that results from mutations in the ADAMTS13 gene. Many USS patients are diagnosed during the second or third trimester of their first pregnancy. We present a patient diagnosed with USS following retinal detachments and intrauterine fetal demise at 34 weeks of gestation. The patient's plasma was tested for ADAMTS13 activity, inhibitor, and antibody. Subsequently, she and her first-degree relatives had ADAMTS13 gene sequencing. Initially, the patient was found to have an ADAMTS13 activity of <5% in the absence of an ADAMTS13 inhibitor (FRETS assay) or antibody (immunoassay). Repeat studies in the months following hospital discharge showed persistent, undetectable ADAMTS13 activity and she was given a clinical diagnosis of USS. Molecular sequencing demonstrated two novel missense mutations in the ADAMTS13 gene: one in the maternal exon 17 (p.Ala690Thr due to nucleotide substitution c.2068 G>A) and another in the paternal exon 22 (p.Arg915Cys due to nucleotide substitution c.2746 C>T). In addition to being compound heterozygous for two ADAMTS13 mutations, the patient also had two maternally inherited single nucleotide polymorphisms: p.P618A (exon 16) and p.A732V (exon 18). Her parents and only sister had normal or near-normal ADAMTS13 activity. Each was heterozygous for one of the novel missense mutations. This case highlights the importance of molecular analysis of the ADAMTS13 gene in patients and family members when the severe ADAMTS13 deficiency does not appear to be autoimmune in nature. J. Clin.

US medical students' knowledge of obstetric fistula in developing countries

Obstetric fistula is a devastating child birth injury affecting millions of women worldwide. This paper explores the knowledge and understanding of medical students at the University of Texas Health Science Center at San Antonio regarding this global public health issue. Obstetric fistula has been eradicated in most industrialized nations, and has therefore faded from view of many modern medical organizations. The United Nations Population Fund has launched a “Campaign to End Fistula” in an attempt to bring global awareness to this preventable and treatable condition. Based on a survey administered to medical students at UTHSCSA, a baseline understanding of this disorder based on current curriculum is reviewed, with the objective of improving future physicians’ awareness of obstetric fistula. Despite a low survey response rate, there was a significant association between greater knowledge about causes, treatment, and complications of obstetric fistula and advanced years in medical school. However, the fourth year medical students averaged only a 70.5 percent of correct responses on the survey, indicating room for improvement in addressing this topic during medical school. ^

OUT-OF-HOSPITAL CHILDBEARING CENTERS IN THE UNITED STATES: A DESCRIPTIVE STUDY OF THE DEMOGRAPHIC AND MEDICAL-OBSTETRIC CHARACTERISTICS OF WOMEN BEGINNING LABOR THEREIN 1972-1979

There is currently much interest in the appropriate use of obstetrical technology, cost containment and meeting consumers' needs for safe and satisfying maternity care. At the same time, there has been an increase in professionally unattended home births. In response, a new type of service, the out-of-hospital childbearing center (CBC) has been developed which is administratively and structurally separate from the hospital. In the CBC, maternity care is provided by certified nurse-midwives to carefully screened low risk childbearing families in conjunction with physician and hospital back-up.^ It was the purpose of this study to accomplish the following objectives: (1) To describe in a historical prospective study the demographic and medical-obstetric characteristics of patients laboring in eleven selected out-of-hospital childbearing centers in the United States from May 1, 1972, to December 15, 1979. Labor is defined as the onset of regular contractions as determined by the patient. (2) To describe any differences between those patients who require transfer to a back-up hospital and those who do not. (3) To describe administrative and service characteristics of eleven selected out-of-hospital childbearing centers in the United States. (4) To compare the demographic and medical-obstetric characteristics of women laboring in eleven selected out-of-hospital childbearing centers with a national sample of women of similar obstetric risk who according to birth certificates delivered legitimate infants in a hospital setting in the United States in 1972.^ Research concerning CBCs and supportive to the development of CBCs including studies which identified factors associated with fetal and perinatal morbidity and mortality, obstetrical risk screening, and the progress of technological development in obstetrics were reviewed. Information concerning the organization and delivery of care at each selected CBC was also collected and analyzed.^ A stratified, systematic sample of 1938 low risk women who began labor in a selected CBC were included in the study. These women were not unlike those described previously in small single center studies reported in the literature. The mean age was 25 years. Sixty-three per cent were white, 34 per cent Hispanic, 88 per cent married, 45 per cent had completed at least two years of college, nearly one-third were professionals and over a third were housewives. . . .

Emergency Obstetric Care: Strategy for Reducing Maternal Mortality in Developing Countries

Twenty-five years have passed since the global community agreed in Nairobi to address the high maternal mortality by implementing the Safe Motherhood Initiative. However, every year nearly three million women die due to pregnancy related causes. This tragedy is avoidable if women have timely access to required emergency obstetric care. Emergency obstetric care refers to life-saving services for maternal and neonatal complications provided by skilled health workers. Since the beginning of the 1980’s, several efforts have been intensified to improve maternal and child health status and reducing the high morbidity and mortality. There was built on a worldwide consensus to provide improved maternal and child health care for addressing the high morbidity and mortality. All participant countries agreed to integrate emergency obstetric care services in their national health care system. Emergency obstetric care is one of the strategies for reducing the maternal mortality as pregnancy related complications are unpredictable. However, many women in developing countries do not have access to essential health care services including emergency obstetric care. Basic emergency obstetric care by skilled birth attendants or timely referral for further comprehensive emergency obstetric care can reduce maternal deaths and disabilities significantly. This paper is based on the results published in PubMed, Medline, Lancet, WHO and Google Scholar web pages from 1990 to 2013.

Practice advisory: interim guidance for care of obstetric patients during a zika virus outbreak

Zika during pregnancy has been associated with birth defects, specifically significant microcephaly. Transmission of Zika to the fetus has been documented in all trimesters; Zika virus RNA has been detected in fetal tissue from early missed abortions, amniotic fluid, term neonates and the placenta. However, much is not yet known about Zika virus in pregnancy. Uncertainties include the incidence of Zika virus infection among pregnant women in areas of Zika virus transmission, the rate of vertical transmission and the rate with which infected fetuses manifest complications such as microcephaly or demise. The absence of this important information makes management and decision making in the setting of potential Zika virus exposure (i.e. travel to endemic areas) or maternal infection, difficult. Currently, there is no vaccine or treatment for this infection.
