In current practice, the device that is most often used is the Pipelle endometrial aspirator. To ensure a maximum amount of tissue for morphological reading, the specimen should be placed on a piece of lens paper or some other adhesive tissue and then immersed in the fixative. By this means, all of the tissue fragments remain tightly attached to the lens paper, rather than floating in the fixative, and no tissue will be lost for histologic examination. In premenopausal women with regular menstrual cycles, histological preparations include the upper portion of the functional layer of the endometrium. This is necessary, for in most instances morphological changes occur in the functionalis as opposed to the basalis layer, and, by inference, provide a clinically useful diagnosis. In cases in which little or no tissue is obtained but the endometrium was penetrated with the aspirator, a repeat procedure should be performed.
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.
Immunity tends to wane by 20 percent a month, leaving those who got their shot in August or September with less than desirable protection by the time they’re exposed.
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:
The methods that have been used in the past were indirect, assumptive and not reproducible. Researchers in Spain have created a new tool which has been shown to be promising for identifying molecular markers for uterine receptivity. Remarkably, as the blastocyst floats within the uterine cavity looking for a place to land, a dialog takes place between the blastocyst and the endometrium. The hormonal preparation of the uterus plays a critical role each month in creating this environment in which the blastocyst can adhere to the endometrium in the hope that implantation will take place.
The uterine lining undergoes changes during the two phases of the menstrual cycle that prepare it for blastocyst implantation. During the proliferative phase, it grows due to the increasing production of estrogen by the ovaries.

Bradley, in Hysteroscopy , Endometrial Biopsy Endometrial biopsy is generally performed in the office with a pipelle instrument. The biopsy is associated with few complications, is performed quickly, and generally is well tolerated by the patient. It has a high sensitivity for detecting endometrial cancer and hyperplasia, but it has a low sensitivity for detecting intracavitary lesions, including polyps and submucosal fibroids.
Lesions encompassing a small surface area and cornual regions are likely to be missed. Additionally, Huang and colleagues16 noted that preoperative pipelle biopsy more often underestimated than overestimated the final grade of endometrial cancer. Patients with persistent symptoms despite a trial of medical therapy, normal biopsy, and normal TVUS need further evaluation with SIS or hysteroscopy.
When hysteroscopy is used alone and the patient has persistent symptoms, TVUS is helpful for excluding intramural fibroids and the rare causes of abnormal bleeding, including ovarian cancer or fallopian tube carcinoma. A meta-analysis of 39 studies reviewing women premenopausal and postmenopausal with endometrial pipelle biopsy noted the following In these subjects, submucosal or intramural fibroids were missed and 63 endometrial polyps remained in situ. These intracavitary lesions rarely respond to hormonal therapy.
Flexible Karl Storz hysteroscope with ancillary biopsy forceps. Targeted directed biopsies are possible in an office setting. The pelvic examination and findings dictate the appropriate investigation tools. In women with a bimanual examination indicating the uterus is less than 12 to 14 weeks in size, TVUS has been the gold standard method of imaging in the premenopausal patient.
Aetna considers the endometrial brush Tao brush an acceptable alternative to an endometrial suction curette e. Aetna considers sentinel lymph node mapping medically necessary for pathologic evaluation and surgical staging in persons with endometrial cancer. Aetna considers the following experimental and investigational because the effectiveness of these approaches has not been established: Background The National Cancer Institute NCI, has stated that there is insufficient evidence to establish whether a decrease in mortality from endometrial cancer occurs with screening by endometrial sampling.
The NCI notes that based on solid evidence, endometrial biopsy sampling may result in discomfort, bleeding, infection, and in rare cases uterine perforation.

Definitions[ edit ] Surgery is a technology consisting of a physical intervention on tissues. As a general rule, a procedure is considered surgical when it involves cutting of a patient’s tissues or closure of a previously sustained wound. Other procedures that do not necessarily fall under this rubric, such as angioplasty or endoscopy , may be considered surgery if they involve “common” surgical procedure or settings, such as use of a sterile environment, anesthesia , antiseptic conditions, typical surgical instruments , and suturing or stapling.
All forms of surgery are considered invasive procedures; so-called “noninvasive surgery” usually refers to an excision that does not penetrate the structure being excised e. Types of surgery[ edit ] Surgical procedures are commonly categorized by urgency, type of procedure, body system involved, degree of invasiveness, and special instrumentation.
Elective surgery is done to correct a non-life-threatening condition, and is carried out at the patient’s request, subject to the surgeon’s and the surgical facility’s availability. A semi-elective surgery is one that must be done to avoid permanent disability or death, but can be postponed for a short time.

Is endometrial biopsy really necessary? Speed points out that in women with suspected luteal phase deficiency, ideally endometrial biopsy should be carried out 1. A defective luteal phase DLP results from a relative deficiency in secretion of progesterone by the corpus luteum. Endometrial biopsy remains the classical way to diagnose an inadequate luteal phase.
A study 2 which evaluated biopsies in women showed that diagnosis of LPD in both infertile and fertile women represents only a chance event; and hence luteal phase evaluation by histological dating of the endometrium is not worthwhile. Moreover because of the discomfort and expense associated with endometrial biopsy, attention has turned to direct measurements of plasma progesterone levels as a means to rule out an inadequate luteal phase. A critical analysis of the accuracy, reproducibility, and clinical utility of histologic endometrial dating in fertile women showed that it does not have the accuracy or the precision necessary to provide a valid method for the diagnosis of luteal phase deficiency or to otherwise guide the clinical management of women with reproductive failure 4.

Rock Abstract It is asserted that examination of the endometrium during the secretory phase yields more information about the time of ovulation degree of progestational change and normality of the endometrium than any other test used in sterility studies. Attention to qualitative changes in 8 morphological factors is most useful in dating the endometrial biopsy.
During the 1st week of luteal activity attention should be focused on changes occurring in gland epithelium: During the 2nd week stromal changes including edema predecidual reaction stromal mitosis and leukocytic infiltration are the key criteria.

Sometimes the independent thinkers prove to be correct, and paradigms shift as a result. You also know that extraordinary claims require extraordinary evidence. When a discovery proves to square with the observable world, scientists make reputations by confirming it, and corporations are soon making profits from it. When a decades-old claim by a “persecuted genius” finds no acceptance from mainstream science, it probably failed some basic experimental tests designed to eliminate self-deception.

Abstract The process of embryo implantation is carried out during the receptive stage of the endometrium in the midluteal phase of the menstrual cycle, known as window of implantation WOI. It has been assumed that the WOI is not a constant variable in all women and the determination of its displacement is of crucial importance, especially for patients with recurrent implantation failure RIF.
Furthermore, in rare cases it could have different duration and position in the menstrual cycle even in the same woman but during different periods.
The major morphologic criteria useful for dating the endometrium throughout the cycle are presented in Fig. 3. In routine dating, the pathologist should avoid bias by evaluating the histologic section before reading the clinical information.
There are a variety of things that can cause pain during sex , but if you’re experiencing not-so-pleasant sensations in the sack, ask your doctor about pelvic floor dysfunction, or muscle spasms in the pelvic area. Heather Gottlieb, a urologist tells WomansDay. Gottlieb adds that medicine such as oral Valium, Valium suppositories, or a topical numbing lubricant, like Lidocaine gel can help alleviate muscle spasms and pain. But don’t worry, you can still orgasm and enjoy sexual sensations: Don’t assume stinging and burning when you urinate means you have a urinary tract infection—you might need a lot more than a cranberry juice and antibiotic cocktail.
Gottlieb, Interstitial Cystitis, or Painful Bladder Syndrome, often mimics a UTI infection, causing symptoms such as burning and stinging, plus a frequent urge to urinate. If it is not a UTI, you should undergo a pelvic exam at your gynecologist’s office. Gottlieb adds that undergoing a cystoscopy, a procedure that examines the lining of the bladder and the urethra is the next step.
A hollow tube equipped with a lens, called a cystoscope, is inserted into your urethra and slowly advanced into your bladder to rule out a urethral diverticulum, Interstitial Cystitis, or a bladder tumor. If you suspect you’re suffering from endometriosis, Dr. Audlin says to be especially aware of pelvic pain during periods and intercourse, uncomfortable bowel movements, and lower back distress, in addition to excessive bleeding.
Removing the issue by surgical means is the primary treatment. You’re probably experiencing common hemorrhoids. Richard Krauss, a gynecologist.
