Endometriosis is an estrogen-dependent inflammatory disease defined by the growth of endometrial tissues outside of the uterus. Epidemiological and clinical studies show that estrogen is essential for the growth of endometriosis. Molecular studies have revealed the presence of Localization of apoptotic cells within the human endometrium and correlation between apoptosis and p21 expression.
It has also changed significantly over time. Most of this extra food energy came from an increase in carbohydrate consumption rather than fat consumption. In the United States, subsidization of corn, soy, wheat, and rice through the U.
In the endometrium, proliferative activity occurs even before the complete cessation of menstruation, i.e. a few days into the cycle. The glands at this earlier stage are relatively straight or, at most, slightly coiled and are found within relatively loose endometrial stroma.
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.
This chapter uses the term luteal phase deficiency LPD. Although it successfully can be argued that LPD is the most common abnormality of the menstrual cycle, its significance as a disease entity is shrouded in controversy over its incidence, means of diagnosis, and legitimacy of treatment. Since the first formal description of LPD in as a possible cause of infertility and recurrent miscarriage by Jones, 1 innumerable investigations have been undertaken in an effort to verify its existence or to characterize its pathophysiology, diagnosis, and treatment.
The consensus of the literature is that LPD does exist and that its cause is multifactorial e. These possible causes are not mutually exclusive in individual patients with LPD, which adds more fuel to the controversy. Obscuring the issue further are related syndromes, such as hyperprolactinemia and hypothyroidism, that are associated with LPD and may induce luteal phase abnormalities secondarily in the presence of otherwise normal ovarian and endometrial function.
An endometrial ablation is a procedure your doctor might consider if you bleed between your menstrual periods, have a heavy flow, or have periods that last a long time.
Complex atypical hyperplasia What are signs and symptoms of endometrial hyperplasia? The most common sign of hyperplasia is abnormal uterine bleeding. If you have any of the following, you should see your health care provider: Bleeding during the menstrual period that is heavier or lasts longer than usual Menstrual cycles that are shorter than 21 days counting from the first day of the menstrual period to the first day of the next menstrual period Any bleeding after menopause How is endometrial hyperplasia diagnosed?
There are many causes of abnormal uterine bleeding. If you have abnormal bleeding and you are 35 years or older, or if you are younger than 35 years and your abnormal bleeding has not been helped by medication, your health care provider may perform diagnostic tests for endometrial hyperplasia and cancer. Transvaginal ultrasound may be done to measure the thickness of the endometrium.
For this test, a small device is placed in your vagina. Sound waves from the device are converted into images of the pelvic organs. If the endometrium is thick, it may mean that endometrial hyperplasia is present. The only way to tell for certain that cancer is present is to take a small sample of tissue from the endometrium and study it under a microscope.

Usually, when cells grow old or get damaged, they die , and new cells take their place. Cancer starts when new cells form unneeded, and old or damaged cells do not die as they should. The buildup of extra cells often forms a mass of tissue called a growth or tumor. These abnormal cancer cells have many genetic abnormalities that cause them to grow excessively. When a mutant version of p53 is overexpressed, the cancer tends to be particularly aggressive. Serous carcinomas are thought to develop from endometrial intraepithelial carcinoma.
Epigenetic silencing and point mutations of several genes are commonly found in Type I endometrial cancer. Pre-cancerous endometrial hyperplasias are also referred to as endometrial intraepithelial neoplasia. This tissue is then examined histologically for characteristics of cancer.

Answered by Experts Q. Could you provide a few links to the major studies showing excessive saturated fat is unhealthy? There has been a backlash against low fat diets, leading people to go in the opposite direction, embracing diets high in saturated fat diets. Can I still get pregnant? You know, that’s honestly a tricky question.

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.
It will make it harder for you to get pregnant. Instead, she will insert very thin tools through your vagina to reach your uterus. The types will depend on what kind of ablation she does.
Bleach is an allergen contained in many household cleaning products. As with many cleaning products, bleach can cause an allergy that.
It has also changed significantly over time. Most of this extra food energy came from an increase in carbohydrate consumption rather than fat consumption. In the United States, subsidization of corn, soy, wheat, and rice through the U. Obese people consistently under-report their food consumption as compared to people of normal weight. Sedentary lifestyle See also: Sedentary lifestyle and Exercise trends A sedentary lifestyle plays a significant role in obesity.
The World Health Organization indicates people worldwide are taking up less active recreational pursuits, while a study from Finland [ ] found an increase and a study from the United States found leisure-time physical activity has not changed significantly. As of , more than 41 of these sites on the human genome have been linked to the development of obesity when a favorable environment is present. The term “non-syndromic obesity” is sometimes used to exclude these conditions.
The correct identification of the appropriate window of implantation in a given patient, by using endometrial receptivity biomarkers, can help to prevent reproductive failure resulting from misplaced timing of the endometrial window of implantation WOI. Although to date no single, clinically relevant morphologic, molecular, or histologic marker capable of indicating endometrial receptivity status has been identified, global transcriptomic analysis of human endometria performed in the last decade has given us insights into a genomic signature that is capable of identifying endometrial receptivity.
As a consequence, a genomic tool named the Endometrial Receptivity Array ERA , based on a customized microarray, was developed, and along with it a specially trained bioinformatic prediction computer algorithm was created to identify WOI timing in the endometrium.
Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have a negative effect on health. People are generally considered obese when their body mass index (BMI), a measurement obtained by dividing a person’s weight by the square of the person’s height, is over 30 kg/m 2, with the range 25–30 kg/m 2 defined as overweight.
Proliferative Phase Proliferative phase change. The glands are simple appearing as circles in cross-section. Mitotic activity is conspicuous. In the endometrium, proliferative activity occurs even before the complete cessation of menstruation, i. The glands at this earlier stage are relatively straight or, at most, slightly coiled and are found within relatively loose endometrial stroma.
As the name suggests, there is brisk cell division with prominent mitotic activity in both the glands and the stroma.
Many women conceive without any problems, despite never observing any egg white cervical mucus at all. For others, however, having little or no fertile cervical mucus can make it more difficult to get pregnant. Even if your cervical mucus is abundant, it may be too thick to allow sperm cells to easily penetrate the cervix. Here are 9 easy ways to increase your supply of good fertile-quality cervical mucus, in order to maximize your chances to conceive.
If you are not sufficiently hydrated, your cervial mucus production will suffer.
Histological dating of timed endometrial biopsy tissue is not related to fertility status. whereas specificity is defined as the proportion of fertile women with an in-phase biopsy based on each definition. Curves are presented for all patients, and for patients sampled in the midluteal and late luteal phase.
Menorrhagia, or hypermenorrhea, is defined as excessive menstrual bleeding and is usually associated with ovulatory cycles. Quantifying the amount of menstrual loss objectively is impractical and unnecessary. Reported pad counts may markedly differ between patients. Several laboratory techniques have been described attempting to quantify blood loss, but it is a cumbersome and time-consuming process. In addition, intermenstrual bleeding IMB is commonly associated with the use of combined oral contraceptive pills COCs.
This type of breakthrough bleeding BTB often occurs during the first few months of use and usually resolves thereafter. Causes include missed pills, drug interactions with anticonvulsants, rifampicin, and certain antibiotics, but BTB most commonly results from an imbalance between the estrogen and progestin that makes the endometrial lining unstable or fragile.
