Evidence • Systematic review of RCTs of antiestrogens in PCOS1: -In 3 RCTs (N = 133) that examined clomiphene (50 to 250 mg/d, 1 to 5 cycles) versus placebo, the pregnancy rate was higher with clomiphene (20% vs 3%); the number needed to treat (NNT) was 6. Live births and miscarriages were not reported. -Limitations: small sample, variable dosing and number of cycles, high dropout rate, poor ad...

The severity of the impact of elevated atmospheric pCO 2 to coral reef ecosystems depends, in part, on how seawater pCO 2 affects the balance between calcification and dissolution of carbonate sediments. Presently, there are insufficient published data that relate concentrations of pCO 2 and CO 2− 3 to in situ rates of reef calcification in natural settings to accurately predict the impact of e...

The outcome of ovulation induction in anovulatory polycystic ovarian syndrome (PCOS) may depend, in part, on the pharmacologic compounds used, but also on individual patient characteristics, such as age, body mass index (BMI), hyperandrogenism, luteinizing hormone (LH), hyper-secretion, anti mullerian hormone (AMH) levels and possibly antral follicle count (AFC) with ovarian volume of these wom...

N-acetylcysteine is the acetylated variant of the amino acid L-cysteine and is widely used as the specific antidote for acetaminophen overdose. Other applications for N-acetylcysteine supplementation supported by scientific evidence include prevention of chronic obstructive pulmonary disease exacerbation, prevention of contrast-induced kidney damage during imaging procedures, attenuation of ill...

Polycystic ovarian syndrome (PCOS) is a disorder of androgen excess and ovarian dysfunction. Hirsutism and elevated free testosterone levels are the most consistent signs of the androgen excess. Irregular, infrequent, or absent menses and infertility are symptoms of ovulatory dysfunction. Obesity is also a feature of this syndrome and contributes to associated metabolic abnormalities. Lifestyle...

Seven patients with anorexia nervosa were studied, three during the acute stages of the illness, and four in whom weight gain had been achieved, but who suffered from persistent amenorrhoea of 18 to 79 months' duration.In the acute stage all patients had low serum luteinizing hormone (LH) levels which were unresponsive to clomiphene citrate. In those who had regained weight the mean basal LH le...

Objective Recently the laparoscopic ovarian drilling (LOD) has been used as a surgical treatment for ovulation in women with polycystic ovarian syndrome (PCOS), although its mechanism and outcomes are still unclear. This study was undertaken to evaluate the in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) outcomes in clomiphene-resistant women with PCOS who were treated with...

BACKGROUND The aim of this study was to develop a system of computerised analysis of digital images of posterior capsule opacification (PCO) that is evidence based, objective and freely available. The paper will present evidence for the reliability and validity of the developed system. METHODS The system of PCO analysis was developed considering current published evidence on visual significan...

Clomiphene citrate is the most used drug for the treatment of female infertility, a common condition in western societies and developing countries. Despite dose escalation, up to 30% of women do not respond. Since clomiphene shares structural similarities with tamoxifen, which is predominantly bioactivated by the polymorphic cytochrome P450 (CYP) 2D6, we systematically explored clomiphene metab...

The aim of this work was to develop a novel (99m)Tc-labelled derivative based on triphenylethylene for breast cancer imaging. (99m)Tc-Clomiphene was obtained with a radiochemical yield of 94.4% by adding (99m)Tc to 1.5 mg Clomiphene citrate in the presence of 10 μg SnCl(2) at pH 7. The optimization of the labeling yield of Clomiphene citrate, with (99m)Tc, is described. The reaction parameters ...
