By , the number of ectopic pregnancies had increased to , Concurrently, however, the case-fatality rate decreased from The increased incidence of ectopic pregnancy has been partially attributed to improved ability in making an earlier diagnosis. Ectopic pregnancies that previously would have resulted in tubal abortion or complete, spontaneous reabsorption and remained clinically undiagnosed are now detected. See Presentation, DDx, and Workup. In the s and s, medical therapy for ectopic pregnancy was implemented; it has now replaced surgical therapy in many cases. See Treatment and Medication. Implantation sites The faulty implantation that occurs in ectopic pregnancy occurs because of a defect in the anatomy or normal function of either the fallopian tube as can result from surgical or infectious scarring , the ovary as can occur in women undergoing fertility treatments , or the uterus as in cases of bicornuate uterus or cesarean delivery scar.
To reassess endometrial morphological criteria of normality identifying the best To date endometrium , should see surface endometrium , but date based on most advanced area; Must biopsy uterine corpus above the level of the isthmus; must. Endometrial maturation, important in the diagnosis of infertile couples , has been evaluated since using the Noyes criteria. It estimates scores for the different.
Tubal infertility and the intrauterine device.
Real-time scanners had rather standard appearance, sizes and fabrication. They are usually portable on 4 wheels with the monitor on the top of the console and rows of receptacles at the bottom to accomodate a variety of scanner probes. See some of these scanners here. By the mid s curvilinear or convex abdominal transducers have come into the market which have a better fit to the Obstetric abdomen and have a wider field of view further from the transducer face.
Curvilinear arrays have completely replaced the linear configuration by the late s. Prior to the s, B-scan ultrasound images made steady progress in resolution and quality, but the improvements were not dramatic and except for a few really top-end brands, most had felt that images in the late s did not have significant improvements over those in the early 80s.
During this period, techiques for resolution and overall image enhancement centered around: See a brief discussion on the linear and phased-array principles. The machine shook the ultrasound community with its excellent resolution and clarity and also the price. Many other companies followed on similar system designs. The early to mid- s was the time with the heaviest proliferation of standard-setting good quality machines. By the early s there were over 45 large and small diagnostic ultrasound equipment manufacturers worldwide.
Image quality saw real improvements in the early s. It is interesting to note that the availability of new and effective technologies to ultrasound scanners had also progressively stemmed from advances in technology in other areas of science such as radar navigation, telecommunications and consumer electronics.

The goal with frozen semen is to breed within a window of 6 to 8 hours prior to ovulation up to 6 hours post ovulation. Accordingly, once the mare receives either HcG or Deslorelin, ultrasound exams occur every 6 hours to evaluate for impending ovulation. There are several options for breeding with frozen semen; the Arizona Equine doctors will work with the owner select the ideal protocol for their mare. Shockwave Shockwave therapy is a treatment modality used by equine veterinarians to treat some tendon and ligament injuries in the leg.
Shockwaves are created by a machine and a veterinarian guides the waves over the injured area for a specific amount of time. Shockwaves improves the healing time of tendon and ligament injuries by increasing blood supply to the damaged area.
This is particularly important in those patients starting on IVF programmes, as these polyps may limit their success.
Transvaginal ultrasound is performed using a special transducer which is slightly thicker than a tampon. It is covered with a disposable latex sheath and lubricating gel, then gently placed into the vagina. The probe sits in the vagina throughout the examination which usually takes between minutes. Most patients find the examination much more tolerable when compared to a cervical PAP smear.
During the scan the sonographer may need to gently press on the abdomen to move bowel out of the way and bring the ovaries and other pelvic structures into view. This also enables any point of tenderness in the pelvis to be identified. Transvaginal or transabdominal ultrasound: Is there a choice? It is a Sydney Ultrasound For Women protocol to offer transvaginal assessment for all Gynaecological and early pregnancy scans.
This is because the transducer is positioned close to the pelvic structures, producing superior image quality, hence, the most detailed and accurate diagnosis. Though a SUFW protocol to offer an internal scan, patients may decline and instead be scanned transabdominally. In certain circumstances a transvaginal ultrasound examination is not possible or not advisable eg.

It is found most commonly on the ovaries and the pelvic peritoneum.
A pelvic or gynaecologic ultrasound is an ultrasound of the female pelvis. Most pelvic ultrasounds are performed using both the transabdominal and transvaginal approaches. Transabdominal ultrasound involves scanning through your lower abdomen. Transabdominal ultrasound usually provides an overview of the pelvis rather than detailed images. The transabdominal assessment is particularly helpful for the examination of large pelvic masses extending into the abdomen, which are not always well viewed with transvaginal ultrasound.
A small amount of ultrasound gel is put on the skin of the lower abdomen, with the ultrasound probe then scanning through this gel. The gel helps improve contact between the probe and your skin.
An Important Announcement from the ARDMS:
Although this technique will not probably replace two-dimensional ultrasound, it is being increasingly used. It has been reported that 3D US is a very high reproducible technique. The endometrium has been paid special attention when using this technique.
Endometrial thickness varies between the proliferative phase mm and the secretory phase mm.
Adapted from Witkin et al. Unsuspected Chlamydia trachomatis infection and in vitro fertilization outcome. Am J Obstet Gynecol Nongonococcal-nonchlamydial salpingitis may also arise de novo as a primary infection. There is less fever, vaginal discharge, and liver tenderness than with gonococcal PID. Despite these differences, the clinical presentation does not adequately distinguish between the two, and reliance on culture is necessary.
Except for the presence of N. As shown in Table 1 , the cervix and vagina of healthy women contain an abundance of aerobic and anaerobic microorganisms. There may be a critical number of organisms needed to overwhelm local host defense mechanisms in the cervix, allowing an infection to ascend to the upper genital tract. There is probably a continuum from bacterial vaginosis to endometritis and salpingitis, because women with bacterial vaginosis are significantly more likely to be diagnosed with PID.
Previous gonorrhea, use of an IUD, frequent douching, and uterine instrumentation predispose to the development of nongonococcal PID. Oral contraceptives may decrease the risk of developing PID, although they have less protective effect than barrier contraceptives. It is logical that women who have used IUDs suffer more tubal infertility and that women who used oral contraceptives have less infertility than women who have used neither method. The introduction of water-soluble contrast media has eliminated the complications of oil embolism and has reduced the risk of granuloma formation, but inflammatory reactions continue to be serious complications of this procedure.

By earning the Midwife Sonography Certificate, midwives gain a critical edge in promoting public safety in women's point-of-care ultrasound. In order to earn the Midwife Sonography Certificate, the certified-midwife must pass both required components in the following order: Practical Examination You may begin acquiring this experience before passing the computer-based examination and then once that examination is passed, you may submit the practical portion.
Once the eligibility requirements have been met and your application has been approved, you can take the computer-based examination. Upon successfully completing the computer-based examination, you must successfully complete the Practical examination within two years. Midwife Sonography Computer-Based Examination The Midwife Sonography computer-based examination is two hours long and contains multiple-choice questions. As a windowed examination, scores for the Midwife Sonography computer-based examination will be available approximately 60 days following the close of the administration via MY ARDMS.
Upon successfully completing the computer-based examination, you will then be eligible to complete the Practical examination within two years from the date of receiving your computer-based results. For more information, review the "Scoring" tab. Periodically we conduct a Midwife Sonography Job Task Analysis JTA and update the Midwife Sonography examination to reflect the frequency and importance of tasks being performed by midwives.
