Pregnancy and Birth

Laparoscopy is one of the most common surgical procedures performed in the United States today. It is the modality of choice for many physicians for removal of ectopic pregnancy, bilateral tubal sterilization, treatment of endometriosis, lysis of adhesions, cholecystectomy, appendectomy, splenectomy, prostatectomy, etc. It is becoming increasingly popular for more complex procedures, including laparoscopic hysterectomy and myomectomy.

Transvaginal Ultrasonography, Sonohysterography, Hysterosalpingography And Operative Hysteroscopy In Predicting Endometrial Hyperplasia

Reproductive endocrinology, a relatively new subspecialty of obstetrics and Gynecology, came of age during the 1980s. The discipline has benefited greatly from substantial recent advances in reproductive biology and allied fields and technologic improvements in computers, ultrasonography, and surgical instrumentation. All of these developments have been applied to clinical practice at an unprecedented rate.

Many clinicians and perhaps some statisticians are at odds regarding the correct application of Bayes theorem in integrated risk assessments of screening programs for Down syndrome1. Most standard textbooks show that the posterior odds = prior odds X likelihood ratio but some publications show the use of prior risk X likelihood ratio to calculate the posterior risk. Bayes theorem does refer to probabilities, which is equivalent to the word "risk"

Since the first report of Doppler ultrasound evaluating high-risk pregnancies in 1983, the fetal arterial system has been extensively studied to determine if abnormal waveforms identify fetuses at increased risk for perinatal mortality.

The Prenatal Ultrasonographic Detection of Myelomeningocele in Patients Referred to Children's Hospital Medical Center

Uterine myomas irrespective of whether they are small and asymptomatic (as in the postmenopausal women) or large and symptomatic (as in premenopausal women) considerably affect uterine artery blood flow velocity. Benign uterine leiomyomas are usually easily recognized with gray-scale ultrasonography, but may sometimes be difficult to differentiate from solid ovarian tumours.

Differential Diagnosis of the Placental Adhesive Disorders by Contrasted Nuclear Magnetic Resonance & Ultrasound - Placenta Accreta and Percreta

Some of you know that I have long been an advocate of miniaturization in Sonography, and predicted that we will all be Cyborgs within 5 years. Well, one of our own, Master Sgt. Cheryl Vance, a diagnostic sonography instructor assigned to the 382nd Training Squadron at Sheppard Air Force Base, Texas (yes, SDMS Region 3 rules the future!) may well be the first Sonographic Cyborg on Earth! Or would that be a "SonoBorg"?

The Air Force has a program, the Education and Training Technology Application Program (ETTAP), specifically geared to introduce new technology into the training environment. This program funds initiatives to incorporate the latest advances in technology into the training setting.

OST's ultrasound laboratory is developing the test methods manufacturers need to assure the safety of their diagnostic equipment. This was accomplished in two related studies concerning hydrophones.

The offering of amniocentesis or chorionic villus sampling (CVS) for chromosome studies is recommended for pregnant women at high risk for Down syndrome. The offering of screening for Down syndrome by serum multiple-marker testing is recommended for all low-risk pregnant women, and as an alternative to amniocentesis and CVS for high-risk women.

A study unveiled today at the 24th annual Society for Maternal-Fetal Medicine (SMFM) meeting brings hope to all pregnant women looking for an early, non-invasive way to assess their risk of delivering a baby with Down Syndrome. The trial reveals that measuring fetal neck fold thickness (nuchal translucency) by ultrasound, combined with a measurement of biochemical markers, is effective in the first trimester.

Pre eclampsia, sometimes called toxemia, is a unique and often dangerous condition that only occurs during pregnancy. Most experts define PRE ECLAMPSIA as an elevation in blood pressure in a pregnant woman of 140/90, with protein in the urine, or swelling (edema) of the feet, hands, and/or face. The condition occurs more commonly during first pregnancies, with twins or triplets, in very young or older women, and when a woman has had pre eclampsia with previous pregnancies.

This series describe an innovative approach for anterior placenta percreta surgery. The procedure has been developed in Argentina and is intended to limit obstetric bleeding and hysterectomy incidence. Though definite results will be reported later, a uterine preservation rate of about 90% with a mean transfusion need of 1000 ml has been achieved.

While growing up in Brownfield, Terry Dubose, an expert in sonography, thought he wanted to be a banker. He enrolled in Hardin-Simmons University after graduating from Brownfield High School in 1962 and earned a bachelor's degree in business administration in 1966.

Confusion about whether to use "ultrasound" or "sonogram," "sonographer" or "ultrasound tech", has done the profession a disservice. The following is the unedited version of the manuscript submitted, including references. The version referenced above was edited.

One of our own Ultrasound@OBGYN.net participants has published an article in the British Medical Journal proposing the use of electronic publication to include the original data with research articles. The article, by David J R Hutchon, consultant obstetrician and gynaecologist. Memorial Hospital, Darlington, County Durham DL3 6HX, proposes several advantages to having the original data available to the readers.

This overview describes and illustrates the clinical applications of three-dimensional transvaginal sonography in reproductive medicine. Its main applications include assessment of uterine anomalies, intrauterine pathology, tubal patency, polycystic ovaries, ovarian follicular monitoring and endometrial receptivity. It is also useful for detailed evaluation of failed and/or ectopic pregnancy. Three-dimensional color Doppler sonography provides enhanced depiction of uterine, endometrial, and ovarian vascularity.

Monochorionic Triamniotic Triplet Pregnancy with a Co-triplet Fetus Discordant forCongenital Cystic Adenomatoid Malformation of the Lung

The visual combination of different modalities is essential for many medical imaging applications in the field of Computer-Assisted medical Diagnosis (CAD) to enhance the clinical information content. Clinically, incontinence is a diagnosis with high clinical prevalence and morbidity rate.

Nuchal translucency is the swelling just under the skin at the back of the fetal neck. It is important because if the fetus has a greater-than-normal amount of swelling at the back of the neck, there is a high likelihood that the baby will have Down Syndrome or a major heart problem or both.

Transvaginal Ultrasound-guided Aspiration and Instillation of HyperosmolarGlucose for Treatment of Unruptured Tubal Heterotopic Pregnancy

The Relationship Between Transvaginal Sonogram and Hysteroscopy Findings in the Assessment of Endometrial Lesions in Postmenopausal Bleeding: A Case Study

Asymmetric and parasitic conjoined twins are rarer anomalies of monochorionic monoamniotic twins, consisting of an incomplete twin attached to the fully developed body of the co-twin.

The Value of 3D Ultrasound Measurement of Placental Volume in Prediction of IUGR, in Cases of Pre-eclampsia

The aim of this study was to evaluate the role of TV-SH in the assessment of tubal patency and to compare these results with those obtained using HSG and laparoscopy.
