Pettker, MD; James D. Goldberg, MD; and Yasser Y. This document reflects emerging clinical and scientific advances as of the date issued and is subject to change. The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. Accurate dating of pregnancy is important to improve outcomes and is a research and public health imperative. As soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained, the gestational age and the estimated due date EDD should be determined, discussed with the patient, and documented clearly in the medical record. Subsequent changes to the EDD should be reserved for rare circumstances, discussed with the patient, and documented clearly in the medical record. When determined from the methods outlined in this document for estimating the due date, gestational age at delivery represents the best obstetric estimate for the purpose of clinical care and should be recorded on the birth certificate. For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the last menstrual period alone, should be used as the measure for gestational age. Recommendations The American College of Obstetricians and Gynecologists, the American Institute of Ultrasound in Medicine, and the Society for Maternal—Fetal Medicine make the following recommendations regarding the method for estimating gestational age and due date:

Much Ado About Careers Well, I met someone this weekend who said he used to be a customs officer and it reminded me of a conversation I had years ago in Moremi Hall in Unilag. Anyway, on that day, I was waiting for my friend, D, in front of the faculty. She came out with this older looking guy who was wearing a suit with his tie hanging loosely around his neck. After waiting for like 3 minutes, she finally caught up with me.

Vasilchenko Nikita Definition Pathological gambling disorder occurs when a person gambles compulsively to such an extent that the wagering has a severe negative effect on his or her job, relationships, mental health, or other important aspects of life. The person may continue to gamble even after they have developed social, economic, interpersonal, or legal problems as a result of the gambling.

Description Pathological gambling disorder is characterized by uncontrollable gambling well beyond the point of a social or recreational activity, such that the gambling has a major disruptive effect on the gambler’s life. People who are pathological gamblers may lose their life savings, and may even commit crimes stealing, embezzling, or forging checks to get money for their “habit. Pathological gambling disorder is an example of a process, or behavioral, addiction , as distinct from an addiction to such substances as food, drugs, tobacco, or alcohol.

In process addictions, the characteristic “rush” or “high” comes from the series of steps or actions that are involved in the addictive behavior.

Then, on October 6, , Michel Mayor and Didier Queloz of the Geneva Observatory announced the first definitive detection of an exoplanet orbiting an ordinary main-sequence star 51 Pegasi. Many known extrasolar planets are many times the mass of Jupiter, approaching that of stellar objects known as brown dwarfs. Brown dwarfs are generally considered stars due to their ability to fuse deuterium , a heavier isotope of hydrogen.

Although objects more massive than 75 times that of Jupiter fuse hydrogen, objects of only 13 Jupiter masses can fuse deuterium.

Overall, a high-quality ultrasound in a woman’s first trimester is the most accurate method of establishing or confirming the gestational age of the fetus. Therefore, if information from an ultrasound is available — or if the date of the woman’s last menstrual period is known — health care providers should estimate the woman’s due date and record it in her files as early as possible, using whatever they believe to be the best obstetrical method.

Women are traditionally told their due date is days, or 40 weeks, after the first day of their last period — a rule of thumb that assumes each woman has a typical day cycle and that each woman ovulates on the 14th day of her cycle. If, for example, an ultrasound performed less than 14 weeks into the pregnancy suggests a due date that differs by more than seven days from the estimated due date generated by a woman’s last period, the woman’s providers should change her due date to reflect her ultrasound.

Before the nine-week mark, a discrepancy of more than five days is reason enough to change her due date. However, Monday’s joint statement from the various medical groups emphasizes that a woman’s due date should rarely be changed based on an ultrasound in her second or third trimester — particularly if she had a previous ultrasound that closely matched the estimate generated according to her last menstrual period. The estimates determined by a woman’s fertility team — for example, the age of the embryo and date of transfer in the case of IVF — should be the primary measure used to determine a woman’s due date, as opposed to subsequent ultrasounds.

Yet even with improved imaging and dating policies, estimated due dates are just that — estimates. Only a small number of women — 5 percent, according to some figures — deliver on their given due date. Traditionally, babies born as much as three weeks before their due dates, or up to two weeks after, have been considered full term. In , however, ACOG redefined what it means for a woman to carry her baby to term , in an effort to prevent non-medically necessary inductions before 39 weeks.

Babies born between 37 weeks and 38 weeks and six days are now considered “early term. Your Blood Volume Increases During pregnancy, the volume of blood in a woman’s body increases by a whopping 50 percent in order to help support the uterus. Accordingly, the amount of blood pumped by the heart increases as well.

References “The technology of prenatal diagnosis is usually presented to us as a solution, but it brings with it problems of its own If you’ve already read it, you may want to skip ahead. All pregnant women in our technology-happy modern society face confusing choices about prenatal testing, its advantages and disadvantages, and its appropriateness for them. Large pregnant women face even more confusion, since prenatal testing can be slightly harder in this population, and the results can be more confusing.

However, since they may be at a somewhat increased risk for problems like neural tube defects, they also face greater pressure than others to have these prenatal tests, even though the tests are often difficult to interpret.

Determination of Gestational Age by Ultrasound Dating Based on Menstrual History Dating by certain menstrual history is inexpensive and readily available. Typically, the EDD is based on a day gestation from the first day of the LMP. Certain menstrual dating criteria assume regular cycles, ovulation at the midpoint of the cycle.

Aetna considers detailed ultrasound fetal anatomic examination experimental and investigational for all other indications including routine evaluation of pregnant women who are on bupropion Wellbutrin or levetiracetam Keppra , pregnant women with low pregnancy-associated plasma protein A, and pregnant women who smoke or abuse cannabis. There is inadequate evidence of the clinical utility of detailed ultrasound fetal anatomic examination for indications other than evaluation of suspected fetal anatomic abnormalities.

Detailed ultrasound fetal anatomic examination is not considered medically necessary for routine screening of normal pregnancy, or in the setting of maternal idiopathic pulmonary hemosiderosis.

Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations. Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels.

The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’. Diminished flow, particularly in the diastolic phase of a pulse cycle is associated with compromise in the fetus. Various ratios of the systolic to diastolic flow are used as a measure of this compromise.

In , the overall incidence of postterm pregnancy in the United States was 5. The incidence of postterm pregnancies may vary by population, in part as a result of differences in regional management practices for pregnancies that go beyond the estimated date of delivery. Accurate determination of gestational age is essential to accurate diagnosis and appropriate management of late-term and postterm pregnancies. Antepartum fetal surveillance and induction of labor have been evaluated as strategies to decrease the risks of perinatal morbidity and mortality associated with late-term and postterm pregnancies.

The purpose of this document is to review the current understanding of late-term and post-term pregnancies and provide guidelines for management that have been validated by appropriately conducted outcome-based research when available.

The risk of stillbirth increases beyond 41 weeks. Oligohydramnios is more common in postterm pregnancies and has been associated with cord compression, fetal heart rate abnormalities, meconium-stained amniotic fluid, and fetal acidosis. Maternal risks are generally those associated with macrosomia and related dysfunctional labors, including severe perineal lacerations, infection, and postpartum hemorrhage.

Two strategies are recommended to reduce the diagnosis of postterm and late-term gestations: Definitive recommendations for fetal surveillance are hampered by the absence of randomized controlled trials demonstrating that antepartum fetal surveillance actually decreases perinatal morbidity or mortality in late-term and postterm gestations.

Prior to the 18th century, caring for pregnant women in Europe was confined exclusively to women, and rigorously excluded men. The expectant mother would invite close female friends and family members to her home to keep her company. The presence of physicians and surgeons was very rare and only occurred once a serious complication had taken place and the midwife had exhausted all measures to manage the complication.

Calling a surgeon was very much a last resort and having men deliver women in this era whatsoever was seen as offending female modesty. However, the subject matter and interest in the female reproductive system and sexual practice can be traced back to Ancient Egypt [6] and Ancient Greece. Living in the late first century A.

References Dating the Beginning of Pregnancy One of the most important aspects of obstetrical care is to date, as precisely as possible, the beginning of pregnancy so that the estimated time of arrival ETA can be calculated sometimes referred to as the estimated date of confinement — EDC. And yet, even with all of the available technology, one of the puzzles of modern obstetrics, is that the obstetrician has not yet learned how to accurately date the beginning of a pregnancy.

Pregnancy can be measured in two different ways. The most common and most often used in clinical obstetrics is the measurement of the gestational age of the pregnancy. The gestational age of the pregnancy is measured from the first day of the last menstrual period. In this way of dating the pregnancy, the pregnancy is 40 weeks in duration on average instead of the actual 38 weeks.

In other words, it dates the pregnancy, on average, two weeks longer than it is. The other way of measuring the dates of the pregnancy is to measure the fetal age. The fetal age of the pregnancy is measured from the time of conception or the estimated time of conception ETC.
