Rana contribute to sexual dysfunctions directly or indirectly by altering hormonal effects on sexual behaviour.41 A higher incidence of polycystic ovarian syndrome PCOS ; is reported in women with epilepsy, 25 especially those on valproate monotherapy and is attributed to initial weight gain, increased insulin resistance leading to hyperinulinemia, increased insulin like growth factor, decreased insulin like growth factor binding protein and sex hormone binding globulin - protein 29, and resulting in hyperadrogenism i.e. increased synthesis of gonadal steroids and an increase in unbound testosterone ; . Hyperandrogenism may cause anovulation by direct effect on the ovary or by negative feed back on FSH secretion, 25 and is reversed by replacing valproate with lamotrigine29 a view contested by others. Recommendations, though not evidence based, are that one should be aware of this problem and should monitor the female patients for possible symptoms and signs of POCS and when detected replace valproate with an alternative AEDs 4 especially enzyme inducing AEDs which by inducing hepatic enzymes lowers the androgens levels by increasing their metabolism. The problem of PCOS is well discussed by Polson 2003 ; .46 Women with cataminal epilepsy Many women have seizures that cluster around menstrual cycles with reproducible patterns and differing between ovulatory and anovulatory cycles.24 In ovulatory cycles seizures occur approximately 3 days before the onset of flow and persist for 6 days and at midcyles and are related to perimenstrual progesterone withdrawal and LH induced midcycle estrogen surge respectively. In anovulatory cycles they are more frequent and dispersed throughout the cycles, as estrogen level in them remains high throughout the cycle. With menopause there is improved control of cataminal seizures while during perimenopause the seizures may increase in frequency and their pattern may change due to fluctuations in gonadal steroids. Hormonal replacement therapy HRT ; in them adversely affects the seizure control.23 The anticonvulsant properties of progesterone have been known since 1942, though the mechanism underlying this observation was a mystery. In the mid 1980s it was found that progesterone metabolites i.e. allopregnanolone neurosteroids ; have powerful anticonvulsant properties and modulate GABA A receptors. Its low level subsequent to reduced progesterone levels may be responsible for cataminal epilepsy. The treatment of cataminal seizures includes monotherapy with most effective AED with adjunctive therapy consisting of: a ; Intermittent therapy with carbonic anhydrase inhibitors acetazolamide Diamox ; 250-1000 mg day given intermittently for 10-14 days surrounding the time of seizure vulnerability. It acts by the inhibition of carbonic anhydrase in glial cells and anticonvulsant properties may be related to production of mild metabolic acidosis. When oral dose is not possible similar dose can be give by IV route. b ; Progesterones such as medroxyprogesterone given in large doses to produce amenorrhea; natural progesterone given over early luteal phase in the dose of 100-200 mg three to four times a day average dose 600 mg day ; to obtain a level of 5-25 ng ml; prometrium 100 mg a day with progesterone topical cream. c ; Testerogens have been studied in the treatment clomiphene, though effective, is associated with potential side effects of hot flushes, polycystic ovarian cysts, and unplanned pregnancy ; .24 d ; Treatment with synthetic or natural neurosteroids and many antiesterogens are under study and may find a role in future.42, 50 Women with epilepsy and bone metabolism Cytochrome P450 hepatic enzyme inducing AEDs i.e., phenytoin, Phenobarbital, Primidone, carbamazepine ; are usually associated with bony changes and metabolic abnormalities and increased incidence of fractures by effecting vitamin D metabolism.6, 21 Many biochemical abnormalities are present in epileptics and are related to duration of AEDs exposure, number of AEDs used and the type of AEDs used and include a decrease in calcium and phosphorous levels, raised alkaline phosphatase, elevated parathyroid hormone and reduced levels of vitamin D and its metabolites along with markers of bone formation and bone resorption. Other suggested mechanisms are direct effect on bone cells including impairment of absorption of calcium, inhibition of response to PTH, hyperparathyroidism and deficiency of calcitonin. Hypocalcemia may adversely affect the seizure control and if not recognized, further increasing the dose of AEDs will further increase the seizure frequency setting a vicious cycle. Recently valproate has also been incriminated even though it has no enzyme inducing properties. 52 The mechanism by which it affects bone metabolism is not understood. Sato, et al., 52 found increased concentration of ionic calcium and suggested that negative feed back via calcium reduces secretion of PTH, which suppresses formation of active vitamin D metabolite 1, 25 OH ; 2 Hence, addition of calcium is not required and in fact it may worsen osteoporosis. There is little information on newer AEDs. Recommendations are that all women with epilepsy should receive vitamin D and calcium supplementation except when taking valproate ; and do active exercise. The menopausal women with epilepsy should be regularly screened for bone mineral density.

Although the body of data is limited, it is suggested that excessive or prolonged exposure to clomiphene citrate more than 12 months ; could increase the risk of ovarian cancer.31 When clomiphene fails, gonadotropin administration frequently is successful in helping women to achieve pregnancy 70 percent ; , but it requires self-injection, is costly, and carries an even higher rate of hyperstimulation and multifetal pregnancy as high as 30 percent ; .32.

Southern Ontario Introduction Fertility Technologies Once the "basic" infertility investigation is completed, ovulation induction is often used to promote fertility. Clomiphene has been one of the mainstays of infertility treatment since it was first used in 1963. Letrozole is a new alternative to clomiphene. Tamoxifene is also used in some clinics. Letrozole is often used in Toronto, Montreal and here in the S.O.F.T. clinic. Because it is new, it is not as widely used and many IMPORTANT NOTICE physicians and pharmacists may not be aware of this use. Recently, the use of Both of these agents are used for ovulation induction and Femara for infertility work in a similar manner but by slightly different has come into question. mechanisms detailed later ; . We do not believe that It has been a consistent observation that if Femara is dangerous in clomiphene can produce ovulation at its lowest dose 50 any way and this is mg for 5 days ; that the pregnancy rate per ovulation is discussed in detail on the higher than if higher doses of clomiphene have to be used. femara information The reason for this is that clomiphene causes negative sheet and on a separate effects on the endometrium and cervical mucous. These information sheet. negative effects may start to overcome the beneficial effect of clomiphene in producing ovulation when higher doses are necessary. In women who are not ovulating, it is sometimes necessary to increase the dose despite this to produce ovulation because clomiphene will not cause ovulation at the starting dose. Because letrozole works in a slightly different mechanism than clomiphene, it does not seem to have the same detrimental effects on the endometrium as clomiphene. This is discussed in more detail in the letrozole information sheet. After extensive use of both clomiphene and letrozole, we wondered how both would work together. The combination of these two drugs has theoretical advantages over increasing the dose of one or the other. Because they both promote ovulation, together, they should provide a more potent ovulation promoting stimulus. In addition, because they have different side effect profiles, by using the minimum dose of each, we should minimize the side effects. Although theories like this are not always true, this does appear to be the case using early observations with the combination. For women who are not ovulating producing an egg ; every month clomiphene or letrozole are usually the first treatment attempted. However, sometimes clomiphene or letrozole are not able to cause ovulation, even in higher doses. This is especially common in women who have the PCOS pattern but have very few spontaneous menstruations. Initial experience in the S.O.F.T. clinic with combined clomiphene and letrozole in women resistant to clomiphene alone has demonstrated ovulation in 46% and pregnancies in 19% of the women who ovulated in their first cycle. Also, clomiphene and letrozole may also be useful in couples with "idiopathic" infertility, mild male factor, endometriosis-associated infertility, mild tubal factor infertility, female age-associated infertility or cervical factor infertility who fail to get pregnant with clomiphene or letrozol alone. Usually if a pregnancy does not occur with. We still get the overwhelming majority of our pharmaceutical feedstocks from antibiotics to botox ; & new drugs from plants & some animals and combivir. Naville A.H., Kistner R.W., Wheatley R.E., Rock J. Induction of ovulation with clomiphene citrate. Fertil Steril 1964; 15: 290. Discussion The results of this study indicate that clomiphene-resistant women with PCOS experience higher pregnancy rates and fewer abortions when they receive combined metforminletrozole in comparison with metforminclomiphene. No significant relationship between age, BMI or duration of infertility in the clomiphene citrate or the letrozole groups was observed. According to the results of this study, mean endometrial thickness on the day of HCG administration was significantly less in subjects taking clomiphene citrate than those who received letrozole 0.55 0.28 versus 0.82 0.13 cm ; , which is similar to the results achieved by Mitwally et al. 2005 ; . However, in the study performed by Al-Fozan et al. 2004 ; , a significant relationship was not found between these two groups. It is probable that the cause of endometrial thickening in patients receiving letrozole is because of improved vascularization as compared with clomiphene citrate Fisher et al., 2002 ; . Other studies also show that clomiphene citrate can cause inadequate endometrial thickness in 1550% of patients Fisher et al., 2002 ; and have negative effects on the quality or quantity of the cervical and endometrial mucosa Mitwally and Casper, 2001 ; . These complications may be attributed to the anti-estrogenic effect and the relatively longer half-life of clomiphene citrate, thus decreasing endometrial thickness by its long-term effect in decreasing the number of estrogen receptors Mitwally and Casper, 2001 ; . A significant statistical relationship did not exist between the frequency of ovulation in either group; neither was there a significant relationship between the mean number of mature ovarian follicles diameter 18 mm ; . the study performed by Al-Fozan et al. 2004 ; , a significant relationship did not exist between the number of follicles measuring more than 14 and 18 mm among patients who were studied for ovulation induction and intrauterine insemination IUI ; in the two groups. However, in the study performed by Mitwally et al. 2005 ; , the mean number of mature follicles was significantly higher in the letrozole group versus clomiphene citrate group. According to the findings of this study, mean total E2 and E2 level per mature follicle were significantly higher in the clomiphene citrate group than the letrozole group on the day of HCG administration 1664.63 versus 981.38 pM l and 783.38 versus 447.60 pM l ; . High supraphysiological levels of estrogen attained during ovarian stimulation with clomiphene citrate may explain some of the adverse effects of clomiphene on the outcome of infertility treatment, although reducing 1434 and lamivudine. We caution that clomiphene citrate should be taken only when it is absolutely certain that the woman is not pregnant.

Monitoring heart rate and oxygen levels of the fetus during ect can detect most problems, and medications are available to correct difficulties and zidovudine. For many years, clomiphene has been the first line treatment choice for women with PCOS. Because it lowers estrogen levels, it increases FSH Follicle Stimulating Hormone ; production which increases the stimulation to the ovaries to develop mature follicles. Unfortunately, clomiphene does not work very well in thin women with PCOS. The anti-estrogen effects are profound enough that although egg development and ovulation may occur, pregnancy will not. This is just an observation, but women that experience side effects from clomiphene such as hot flashes will not conceive on clomiphene.

Side effects of clomiphene include mild headache, mood swings, vaginal dryness, and ovarian cysts and compazine. Showing an increased risk of birth defects during the use of clomiphene.17 Clomiphene is used as monotherapy in appropriately selected anovulatory women in whom ovulatory dysfunction with adequate serum estrogen concentrations has been demonstrated. Some gynaecologists prescribe in addition corticosteriods in the case of overproduction of adrenal androgens, or use of bromocriptin when moderate hyperprolactinemia co ; exists. The primary use of hMG hCG is substitution of deficient pituitary gonadotropin release, nowadays mainly because of primary pituitary disease. However, our analysis shows that clomiphene is often followed by hMG hCG as a secondary drug for induction of ovulation. Also hCG is often used in the same cycle as clomiphene, or in a following cycle without clomiphene treatment. It is reasonable to assume that in medical practice one starts 'blind' with the use of clomiphene. The number of other ovulation related drugs during the two-years follow-up period does not increase with the number of cycles of treatment: women who were only treated for one or two cycles with clomiphene used as many different ovulation related drugs as those who were treated for more than 6 cycles. Besides the three drugs under study clomiphene, hCG, and hMG ; the most commonly prescribed hormones or hormone related drugs were progestins, busereline and urofollotropine. Progestins are used to determine whether estrogen concentrations are sufficiently high to merit the use of clomiphene as an ovulation-inducing drug. Busereline and urofollotropine were frequently used in the group of hMG hCG users. In the Netherlands, busereline is registered for the treatment of disseminated hormone dependent carcinoma of the prostate.35It has a relatively short half-life and therefore it has been adopted as a means of creating hypogonadotrophic state, thereby facilitating follicular stimulation with hMG, especially in "controlled" ovarian hyperstimulation with hMG hCG as currently used in in vitro fertilization protocols. This accounts for its prescription to users of ovulation-inducing drugs, and its use should thus be considered as experimental. Nevertheless, it was prescribed to 11% of the clomiphene users and to 38% of the hMG hCG users, probably as part of IVF treatment. Interestingly, non-steroidal antiinflammatory drugs and analgesics were also frequently used. The percentage of women who used non-steroidal antiinflammatory drugs is much higher 27.2 and 36.9% ; than that found in a study on pharmacy records of pregnant subjects.24In that study only 2.8% of the women used a drug from this category in the 6-month period prior to pregnancy which is a period comparable to that used in the women in the present study ; . Most probably this higher use of nonsteroidal antiinflammatory drugs is the consequence of ovulatory or premenstrual pain secondary to the use of the ovulation-inducing drug. We should keep in mind the fact that possible interactions between clomiphene and such nonsteroidal antiinflammatory drugs, other ovulation-stimulating drugs or other drugs frequently used under these conditions, might contribute to the suspected teratogenic effects of clomiphene. Thirty percent of the women who used clomiphene were treated for 6 or more cycles. It is well known from the literature that the effectiveness of ovulation induction decreases significantly after three cycles of treatment. The recommended maximum number of cycles of treatment of clomiphene is, according to the litera. Procter & Gamble Pharmaceuticals, Inc. May 2007 and prochlorperazine. Clomiphene is not recommended for use in children. It is painfully clear post-Lucknow that as long as Section 377 exists there is no possibility of anyone approaching HIV from a health perspective alone. The formation of alliances and coalitions under a human rights framework--in which queer groups work along with feminist groups, civilliberties groups, and groups working on HIV AIDS to understand and address the ways in which health intersects with the state's need to regulate sexuality--has now, after the experiences and lessons of Lucknow, become a critical necessity.31 The emergence of this alliance would, of course, depend upon the willingness of diverse groups to take on broad concerns beyond their narrow "core" concerns ; . Thus it would mean that sexuality-based groups would have to take on broader human rights concerns, and vice versa. Constitutional Challenges to Section 377: Homosexuality as Framed by Hindutva While the Lucknow case is emblematic of how work on health issues with the MSM community has become caught up in a wider debate around homosexuality, the state's response to the constitutional challenge to Section 377 illustrates how clearly Hindutva is implicated in concerns around health. The concern with sexual health postLucknow has become essentially a concern about homosexuality. As the government's response to the petition challenging Section 377 clearly illustrates, the concern with ho14 Vol. 7 No. 2 and coreg and clomiphene.

For young patients with pco ovaries on ultrasound, if clomiphene fails to achieve a pregnancy in 4 months time, we usually advise laparoscopic surgery as the next treatment option, this is because leos helps us to correct the underlying problem; and about 80% of patients will have regular cycles after undergoing this surgery, of which 50% will conceive in a year's time, without having to take further medication or treatment.
Clomiphene ovulation induction compared to clomiphene citrate, conclusecondionsecond. Obstruction, irritation or compression. They may have been immunocompromised by their diseases, drug treatment or radiotherapy. Operations or instrumental investigations such as cystocopy or retrograde pyelogram put them at risk of infection. Pathogens in the urinary tract infection in general practice mainly come from the patient's own body, such as E. Coli from his gut, while those in hospital may have come from the environment or other patients. These latter pathogens have been exposed to many antibiotics and are very often resistant to multiple antimicrobials. Hence, it would be inappropriate to extrapolate the results of research from the hospital setting to general practice. It would be more so to extrapolate results of researches done overseas to Hong Kong practice, be they done in hospital or in general practice. In Hong Kong, we have a fee-for-service medical system. Patients have to pay for every prescription or investigation. Many doctors opt to omit a formal urine culture and sensitivity test before treating their patients merely because the patient cannot afford them. In this case, the doctor provides an empirical treatment according to his own experience. It would be ineffective, if not dangerous, if he has no knowledge of the most probable pathogen or antibiotic sensitivity in his district of practice. The aim of this study is to define the spectrum of pathogens responsible in the urinary tract infections in general practice as compared to that in hospital practice, and compare the result with those from hospital and general practice in Australia and United Kingdom.
