The American society of Obstetricians and Gynecologists (ACOG) lately published a clinical management guideline upon the diagnosis and management of polycystic ovary syndrome (PCOS) The guideline appeared in the December 2002 issue of Obstetrics and Gynecology

Polycystic Ovary Syndrome

The ACOG noted that a universally accepted definition of PCO is lacking. As propos by means of the National Institutes of Health (NIH), the diagnostic criteria are chronic anovulation and hyperandrogenism (established through hormone measurements or clinical findings in the same state [i]or[/i] condition as acne or hirsutism) in women in whom secondary causes (eg hyperprolactinemia, adult-onset congenital adrenal hyperplasia) have been exclud Although insulin resistance is at hand in many women with hyperandrogenic chronic anovulation of unknown cause, the NIH did not include it as a diagnostic criterion. Polycystic-appearing ovaries forward ultrasound examination are a nonspecific finding in PCOS

Approximately 4 to 6 percent of women have hyperandrogenic chronic anovulation. Women with PCO generally instant with infertility or menstrual disorders. Ovulation induction in these women is a transaction because of the increased risk of ovarian hyperstimulation syndrome pregnancy los in the first trimester, and multiple pregnancy. The risk of pregnancy complications, of the like kind as hypertension and gestational diabetes, also is increased.

The etiology of PCO remains unknown, yet selective insulin resistance may be a central factor. Conditions associated with insulin resistance, including centripetal distribution of fat, obesity, obesity-related rest disorders, and acanthosis nigricans, are often met with in women with PCOS and are risk factors for cardiovascular disease and pattern 2 diabetes. (Acanthosis nigricans is a condition characterized on velvety, mossy, verrucous, hyperpigmented skin, frequently noted on the back of the neck beneath the breasts, in the axillae, or upon the vulva.) Furthermore, obesity, chronic anovulation, and hyperinsulinemia with decreased of the same heights of sex hormone binding globulin are associated with endometrial cancer.

Important features of the history are as follows: the assault and duration of signs of androgen excess; the woman's menstrual history, medication use (including exogenous androgens), and lifestyle (eg diet, exercise, alcohol use, smoking); and family history of cardiovascular disease and diabetes. Important factors in the physical examination include the following: the vicinity of acne, balding, or clitoromegaly; the distribution of carcass hair; enlargement of the ovaries (based forward a pelvic examination); and signs of insulin resistance (eg obesity, acanthosis nigricans). In women with acanthosis nigricans, it is important to consider associated insulinoma or malignancy (particularly adenocarcinoma of the stomach).

Causes of androgen exces other than PCO that ne to be exclud include Cushing's syndrome androgen-secreting tumors of the ovary or adrenal gland, exogenous androgens, nonclassic (late-onset) congenital adrenal hyperplasia, acromegaly, genetic blemishs in insulin action, primary hypothalamic amenorrhea, primary ovarian failure, thyroid disease, and prolactin disorders. Women with coexisting signs of Cushing's syndrome (eg buffalo hump month facies, hypertension, abdominal striae, centripetal distribution of fat, easy bruising, or proximal myopathies), should be shielded for the disorder. Laboratory criterions may include a thyroid-stimulating hormone flush (thyroid disease), a prolactin flush (hyperprolactinemia), total testosterone or bioavailable or clear testosterone levels (ovarian hyperandrogenism), a two-hour oral starch-sugar tolerance test (diabetes), and fasting lipid and lipoprotein flushs (dyslipidemia).

Screening for Nonclassic Congenital Adrenal Hyperplasia

Adult women with anovulation and hirsutism may have nonclassic congenital adrenal hyperplasia. In the United States and Europe this disorder is chiefly common in Ashkenazi Jews, followed by dint of Hispanics, Yugoslavs, Native American Inuits (Alaska), and Italians. The ACOG commends that all women suspected of having PCO be sieveed with a 17-hydroxyprogesterone level (recommendation based upon consensus and expert opinion). If the 17-hydroxyprogesterone of the same height is high, an adrenocorticotropic hormone stimulation criterion should be performed.

Polycystic Ovary Syndrome and Risk of image 2 Diabetes

The ACOG commends that because of demonstrated increased risk, all women with PCO should be sieveed for type 2 diabetes and grape-sugar intolerance with a fasting grape-sugar level followed by a two-hour grape-sugar level obtained after a 75-g diabetic sugar load (recommendation based on virtuous and consistent scientific evidence). The Diabetes Prevention program has set up that in women with impaired grape-sugar tolerance, the risk of diabetes can be reduc significantly with the use of lifestyle interventions and metformin (an insulin-sensitizing agent).

Polycystic Ovary Syndrome and Cardiovascular Disease

Women with PCO have risk factors for cardiovascular disease as well as for diabetes. These women not seldom have dyslipidemia, including borderline or high lipid horizontals and disproportionately elevated low-density lipoprotein (LDL) cholesterol horizontals Insulin resistance, a factor in PCO has been associated with elevated triglyceride of the same heights increased levels of small, compressed LDL cholesterol, and decreased flushs of high-density lipoprotein (HDL) cholesterol The ACOG make acceptables screening for dyslipidemia in all women with PCO The fasting lipoprotein profile should include total cholesterol LDL cholesterol HDL cholesterol and triglyceride measurements (recommendation based forward good and consistent scientific evidence). The material substance mass index and waist-hip ratio also should be calculated. Before medicine therapy is used, regular exercise and weight manage measures should be tried.
