Progesterone. Drugs used to terminate pregnancy act by antagonizing the action of progesterone mifepristone; RU 486 ; , inducing myometrial contractions prostaglandins; eg, misoprostol ; , or inhibiting the development of the trophoblast methotrexate ; . The article comments on mode of action, efficacy, and adverse effects of each. Medical termination can be performed as soon as the pregnancy has been confirmed. It is not recommended after 9 weeks of gestation because of the high incidence of failure and uterine bleeding. Success depends on the duration of pregnancy. Medical abortion requires more clinic visits than surgical abortion. Methotrexate or mifepristone can be given in the clinic and the patient sent home. She usually returns to the clinic to take the prostaglandin. Then the patient may wait under observation for 3 to 6 hours to determine outcome. Some women find this burdensome. If abortion fails or results in incomplete abortion or excessive bleeding, surgical termination is performed. Medical termination is acceptable to the majority of women. Most say they would choose it over surgical abortion if facing the choice again. However, for pregnancies over 50 days, medical abortion is more painful and less effective than surgery, so the latter may be more acceptable. Mifepristone RU 486 ; has been approved by many countries worldwide for termination of pregnancy. The U.S. FDA has granted mifepristone approvable status.

James Segars, Reproductive Endocrinology, Reproductive Biology and Medicine Branch, National Institute of Child Health and Human Development, Bethesda, MD Objective: We review ovarian reserve testing prior to assisted reproduction, the concept of diminished ovarian reserve DOR ; or ovarian insufficiency, available screening tests, and diagnostic implications. Design: A PUBMED computer search to identify relevant literature. Result s ; : The prevalence of ovarian insufficiency varies with age. Because the prevalence of the condition varies with age, there are no ideal, highly predictive, accurate screening tests for ovarian insufficiency. At present, most providers use basal FSH values as a screening test due to the widely available nature of the test, but if a single threshold value is used, the test is not highly predictive. AMH has recently shown higher sensitivity, specificity and receiver-operator characteristics, but the test is not widely available. Ovarian volumes and antral follicle counts also exhibit relatively high sensitivity and specificity but are operator-dependent. Our analysis supports dividing impaired ovarian reserve into two groups: age-dependent ovarian aging physiologic ; and premature non-physiologic ; reductions in the oocyte pool. Since the positive predictive value of screening tests is low for women under age 35, any positive results should be corroborated with additional information. Screening for ovarian insufficiency for women over 40 years of age is only useful if abnormal, because normal results are not reassuring. Due to the marked effect of age, we suggest use of a nomogram of basal FSH and age rather than a specific threshold value or cutoff to diagnose impaired ovarian reserve. Conclusions s ; : Proper interpretation of screening tests for ovarian insufficiency in couples considering ART is important since the presence of impaired ovarian reserve is associated with poor pregnancy outcome. The condition of premature non-physiologic ; ovarian insufficiency warrants additional research.

Antiresorptive agents such as the bisphosphonates, calcitonin, tamoxifen, and raloxifene are useful for the prevention or treatment of osteoporosis. Bisphosphonates are stable analogs of pyrophosphate and exert effects primarily on the osteoclast. Newer bisphosphonates such as risendronate are being studied. 1. Comparison of alendronate and estrogen. Data regarding the relative efficacy of the bisphosphonates vs. estrogen are available for effects on bone density but not for fracture prevention. The most commonly used bisphosphonate, alendronate, appears to exert an antiresorptive potency similar to that of estrogen when used at low dose 5 mg ; Fig. 2 ; .

Sexual differences in the renal response to the diabetic state. A number of potentially pathogenic pathways for diabetic nephropathy may be influenced by sex steroids. Sexual differences in blood pressure have been discussed above; the following sections will examine intracellular pathways of importance in diabetic complications and renal hypertrophy. PKC and Sex Steroids One major cellular system that is dysregulated in diabetes is PKC Fig. 1 ; 87 ; . Hyperglycemia increases production of diacylglycerol DAG ; , which stimulates PKC 87 ; . PKC may in turn stimulate MAPK, which may lead to production of growth factors that ultimately promote accumulation of extracellular matrix materials in the glomerular mesangium and tubulointerstitium 164 ; . Both estrogens and androgens induce PKC activity in certain tissues, including breast cancer cell lines and male reproductive organs 11, 29, 98 ; . Sakabe et al. 147 ; described PKC activation in cultured thymic epithelial cells exposed to androgen or progesterone; estrogen had no effect in this model. Kidney cells have not been studied for sex steroid effects on PKC. Adult male control rats treated with an oral PKCinhibitor showed no difference in kidney weight from untreated controls; however, renal growth was virtually complete at initiation of this study 86 ; . This does not rule out a role for PKC and sex steroids in normal renal growth. Takahara et al. 160 ; reported data from mice overexpressing PKC- 2 in the vasculature; at 4 mo of age, male mice demonstrated a 25% increase in renal weight compared with controls and females. PKC- inhibitors have been shown to prevent mesangial expansion in the diabetic db db mouse, a model of DM2 85 ; . Polyol Pathway and Sex Steroids All cells have the capability to convert glucose to sorbitol via oxidation of NAD P ; H with the enzyme aldose reductase 176 ; . Cells in which glucose uptake is not insulin dependent will have an excess of substrate and typically accumulate sorbitol in DM. This process can produce several effects. First, the osmotic balance of the tissue is disturbed because of the accumulation of sorbitol. Second, consumption of NAD P ; H in these reactions may alter the redox potential of the cell, making it less able to deal with oxidant stress. Third, sorbitol may then be converted to fructose, which promotes nonenzymatic glycation of proteins and accumulation of advanced glycation end products. All of these effects of the polyol pathway are capable of stimulating processes that ultimately produce TGF- Fig. 1 ; . In 1986, diabetes-induced changes in polyol metabolism and collagen cross-linking were shown to be prevented by castration in streptozotocin rats, linking this metabolic pathway to androgens 171 ; . The mechanism of this link remains unclear. Members of the aldo-keto reductase superfamily contain androgen response eleAJP-Renal Physiol VOL and seroquel.
Numerous different progesterone creams are available over-thecounter in the United States and many are available through compounding pharmacies in Canada or surreptitiously through health food stores. For most products, there is little consistency or quality control. The products can be categorized as follows: 1 ; Those that contain no progesterone, but variable amounts of progesterone precursors that are generally obtained from the inedible Mexican wild yam Dioscorea barbasco ; . There is no enzymatic process in the human body to convert these precursors into progesterone. 2 ; Those that contain progesterone that has been synthesized in a laboratory, often from Mexican wild yam or soy precursors. While these products contain variable amounts of chemically defined progesterone, absorption through the skin is variable and usually poor.60-62 In a 12-week randomized trial, no progestational effect on the endometrium was noted in 21 estrogen-primed women using standardized daily doses of 16 to mg of micronized progesterone cream.63 In a one-year randomized controlled trial, a daily dose of 20 mg progesterone cream produced no protective effect on bone density, yet produced a small but significant improvement in vasomotor symptoms compared to placebo.64 Although these products claim to treat menopausal symptoms, premenstrual syndrome, and osteoporosis, the amount of progesterone absorbed from the various preparations is highly variable, and should be considered inadequate to provide endometrial or bone protection.63, 64 While prescription preparations of progesterone and progestins are absorbed through the skin norethindrone-containing patches ; or vaginal mucosa micronized progesterone tablets administered vaginally, progesterone vaginal suppositories or progesterone vaginal gel ; , there is insufficient evidence to conclude that transdermal absorption of the non-prescription progesterone creams is similarly effective.
Friendship formation and development is an important aspect of adolescence. However, little research has examined the friendships of adolescents with chronic illness. In this study, we interviewed 132 early adolescents with Type 1 diabetes and 131 healthy controls all ages 10-12 ; . We compared friendships of adolescents with diabetes to healthy adolescents' friendships on five domains: intimacy, emotional support, instrumental support, dominance, and conflict. Boys with diabetes experienced low levels of intimacy and emotional support compared to girls with diabetes and healthy adolescents. Healthy boys showed marginally more dominance in their friendships than did the others. We next examined the relation of the friendship domains and their interactions with health status on psychological outcomes. In general, positive aspects of friendship were associated with positive outcomes for all adolescents e.g., emotional support from friends was associated with fewer difficulties at school, less anger, more self-worth, and more social competence ; and negative aspects of friendship were associated with negative outcomes e.g., conflict was associated with more difficulties at school and more anger ; . Some interesting marginal interactions also emerged. For adolescents with diabetes but not healthy adolescents, instrumental support from friends was associated with adaptive skills. For healthy adolescents, but not adolescents with diabetes, intimacy was associated with more behavioral problems. This raises the possibility that aspects of friendship serve different roles for chronically ill adolescents. Finally, we examined the relation between domains of friendship and diabetes outcomes. Instrumental support from friends was associated with worse metabolic control, dominance was associated with worse diabetes quality of life, and none of the aspects of friendship were associated with self-care behavior or hypoglycemic episodes.

Towards the control of the hypertension epidemic. The Philippine experience Abarquez R.F. Jr. Philippine Heart Center, East Avenue, Quezon City Philippines Philippine Journal of Internal Medicine Philippines ; , 1995, 33 2 ; As of 1990 the Philippines is 2nd to Indonesia in hypertensive-related mortality. To reverse this trend, hypertension control strategies involve health provider and client perceptions of the issues. A recent Philippine Society of Hypertension PSH ; survey which included pooled historical data of 25, 427 respondents showed 15% clinical practice hypertension prevalence. Most initial work-up includes ECG, urinalysis, cholesterol and sugar blood levels and chest x-ray examinations. Antihypertensive monotherapy preferences were calcium antagonists 25% ; , betablockers 8% ; , and diuretics 7% ; . Client awareness of being hypertensive is 52% with only 23% admitting good BP control. Almost 60% are asymptomatic at hypertension discovery. Role of diabetes, pregnancy, renal and eye problems in hypertension obtained low perception. Use of garlic and cleansing diet were perceived to be beneficial in BP control despite lack of documentation. Antihypertensive medication compliance was 33% in industrial patients compared to 51% in the general population. From this pooled survey data, programs and strategies will emerge in order to control the hypertension epidemic. A clear message seems obvious - it is wrong to assume that a patient understands a doctor's explanation readily and rebetol.
Medications are very effective to treat fibromyalgia.
Do the rates of such services performed during hospitalizations. Physicians forget to prescribe indicated tests and therapies; patients receive care from multiple sources and therefore contraindicated therapies can be prescribed, as with calcium channel blockers in heart failure ; , 19 and patients are sometimes non-adherent to their treatment. A RAND study of 439 indicators of the quality of health care demonstrated that nearly half of services important to optimal outcomes in quality care were not being delivered.20 Because of the diffuse nature of outpatient care, alert and reminder systems that may be effective in a hospital setting are often unsuited to the outpatient world. Multiple strategies have been attempted to increase physician and patient adherence to established clinical practice guidelines. Many of these strategies have recognized that people adopt innovations at varying rates. Adopting an innovation ie, a behavior associated with a practice guideline ; is different from acquiring new knowledge. The classic work of Everett Rogers on innovation diffusion theory showing an S-shape adoption curve from innovators and early adopters through the early majority, late majority, and late adopters or resisters ; 21 suggests that physicians will adopt an innovation such as the findings of a major clinical study or a clinical practice guideline ; if the potential adopter judges that the benefits of the innovation outweigh its risks, if it can be tried without disrupting usual workflows, if the physician can watch others using it, if respected "opinion leaders" are using the innovation, and if the innovation can be tried out without involving great commitment. However, the method of innovation diffusion plays a key role in physicians' adoption as well. Passive information dissemination brochures, mailings, and continuing education courses ; that does not provide patient-specific, clinical scenario-specific feedback has little influence on physician performance, while active participation eg, workshop groups ; , use of opinion leaders, and patient-specific guideline alerts showed improvement in measured performance and sometimes in outcomes.13, 2225 Studies of use of computer-supported decision support systems such as alerts and reminders at the point of care or shortly thereafter ; , which and ribavirin.

Prostaglandin F2 production by the primate and human corpus luteum is well established, just like the changes in relative concentrations of PGE2 PGF2 and their binding sites in early, midand late corpora luteal phases. The number of binding sites has been shown to vary with the age of the corpus luteum during the human menstrual cycle. The early luteal phase is characterised by elevated PGE2 concentrations, corresponding to peak progesteroone levels, while the late secretory phase is associated with lower progewterone levels and markedly higher PGF2 37, 38. In most mammals, PGF2 originates in the endometrium. Recent studies have proposed that in humans, endometrial extraluteal PGF2 initiates luteolysis whereas luteal PGF2 may contribute to structural luteolysis 39. The high concentration of the agent is responsible for terminating the lifespan of the corpus luteum if fertilization fails to take place 40, 41. 1.4.2 Fetal Circulation and requip and progesterone.

Recent studies have demonstrated that decreased fertility in lactating dairy cows is associated with high levels of plasma urea nitrogen PUN ; , although the mechanism by which this occurs is unknown. The objective of this study was to monitor changes in the uterine environment during chronic elevation of PUN. Dairy cows n 8 ; between 40 to 100 days of lactation were studied on day 7 after estrus. Cows were determined to have ovulated by observation of a corpus luteum CL ; using ultrasonography. Infusion through jugular vein catheters of either saline n 4 ; or urea .01 g urea hr kg bwt; n 4 ; was continued for 24 hrs. Treatments were then switched between groups for a second 24 hr infusion period. Blood samples were collected every 1 to 2 hours to monitor PUN levels. Uterine pH was recorded at 6-hr intervals by inserting a steel cannula containing a micro pH electrode through the cervix and into the uterine lumen. After the termination of each infusion period, 30 ml of sterile saline was flushed into the uterine lumen and immediately retrieved. During urea infusion, the mean PUN level increased from the baseline during saline treatment 16.1 1.5 mg dl ; to that commonly found in high producing dairy cows fed a TMR 23.3 1.0 mg dl; P .001 ; . Uterine pH declined during urea infusion from a mean of 7.18 .03 at 0 hr 6.88 .03 at 18 hr .06 ; , but remained unchanged in controls 7.16 .04 to 7.27 .04 ; . PGE2 and PGF2 levels in uterine lavages were not different between treatments. Proteins in uterine lavage samples were characterized using SDS polyacrylamide gel electrophoresis SDS-PAGE ; . Protein profiles appeared to be similar among cows with no obvious differences being observed. Decreases in uterine pH during the infusion periods were correlated with higher plasma progesterone concentrations P .04 ; . This study demonstrates that increased PUN can exert direct effects on the uterine environment. However, the mechanism by which changes in the uterine environment may affect fertility in high producing dairy cows needs further study. Key Words: Cows, pH, Urea and ropinirole.

Slide 12 Several modifiable risk factors for breast cancer are known. Just as estrogen exposure from early menstruation may increase a woman's risk of breast cancer, several modifiable risk factors are related to estrogen exposure. Having no children or having children after age 30 slightly increases breast cancer risk. The use of oral contraceptives that contain estrogen and progesterone seems to slightly increase the risk of breast cancer. However, this risk returns to normal 10 years after discontinuing usage of these agents. Hormone replacement therapy with estrogen plus progesterone by postmenopausal women increases the risk of developing and dying from breast cancer among current and recent users. The risk of breast cancer returns to normal five years after stopping HRT. The use of estrogen replacement therapy, on its own, after hysterectomy does not appear to affect breast cancer risk much, if at all.
