After admission, hyperglycemia 150 to 160 mg dL was treated by insulin, according to local stroke management guidelines, 19 irrespective of whether the patient had been treated with insulin before. Oral antidiabetic drugs were continued in 34 of patients 57% ; . The remaining cases were treated with insulin. All patients received a CT scan, blood pressure and temperature measurement, and ECG immediately after admission and, depending on type and severity of the infarct, a repeated CT or MRI after 1 to 7 days to assess final infarct volume. Doppler duplex sonography was performed, usually within 24 hours. Blood pressure was maintained within systolic values of 140 to 190 mm Hg by means of colloidal or starch infusion or, if elevated, by calcium antagonists or urapidil. Patients without contraindications received thrombolysis with recombinant tissue plasminogen activator within 3 hours. Heparin was administered intravenously in an unfractionated dose-adjusted manner in cases with presumed high stroke recurrence risk or low-flow conditions atrial fibrillation, high-grade carotid stenosis, dissection ; or with unfractionated heparin according to local stroke treatment guidelines. Exclusion criteria were hemorrhagic stroke, subarachnoid hemorrhage, transient ischemic attacks TIAs ; , and cerebral sinus thrombosis. Stroke etiologies were defined according to the Trial of Org 10172 in Acute Stroke Treatment TOAST ; .20 End points were as follows: 1 ; in-hospital case mortality rate; 2 ; motor impairment, assessed by the Canadian Neurological Scale CNS ; 21; 3 ; length of hospital stay; 4 ; requirement of intensive care; 5 ; clinical course within the first 72 hours after admission, derived from the medical record; 6 ; in-hospital complications eg, pneumonia, urinary tract infection, recurrent stroke, hemorrhage and 7 ; Rankin Scale score at follow-up 3 months after stroke ; .

Determined that the best line of treatment involves parental reassurance and education. No evidence was found to support the use of pharmacological agents in the treatment of GOR. Although both pro-kinetic agents and proton pump inhibitors may reduce oesophageal acid exposure, they do not have any effect on the symptoms of GOR, including infant irritability; which will improve with time, regardless of treatment. In contrast, this review found that antacids and feed thickeners were most effective in decreasing the symptoms, but not gastric acidity associated with GOR. There was no evidence supporting the use of positioning in decreasing the symptoms. When a parent presents to a doctor with an infant that vomits after every feed, he she will find it difficult to accept that regurgitation is a normal occurrence. Providing parents with education surrounding this common and normal physiological process is essential to reducing their anxiety and concern. However, if an infant shows features of failure to thrive with persistent respiratory symptoms and signs of oesophagitis, which are manifestations of GORD affecting only 1 in 300 infants, then this would require admission and further evaluation. Gastro-oesophageal reflux is a self-limiting condition that usually resolves by six to 12 months of age. Infant irritability tends to improve with time, which could be a confounding factor in any study involving therapeutic intervention of GOR. Reassurance and parent education is paramount and should be the first-line of management. If parents insist, conservative treatment may be employed and

A number of studies are beginning to evaluate combining fulvestrant with aromatase inhibitors. SWOG-S0226 will compare anastrozole to anastrozole plus fulvestrant as first-line therapy in postmenopausal women. In the UK, the SoFEA study will enroll patients who have had disease progression while on an aromatase inhibitor. Those patients will be randomly assigned to fulvestrant, exemestane, or fulvestrant plus anastrozole. The rationale behind that trial is the data suggesting that estrogen-deprived MCF-7 cells become supersensitive to lower doses of estradiol and, hence, are stimulated again. The third arm of that trial will keep the estradiol levels low and then come in with fulvestrant to determine if that strategy is different from fulvestrant alone without estradiol suppression. -- John F R Robertson, MD It remains unclear where fulvestrant should be utilized in the sequence of hormonal therapies for metastatic disease. Several new North American trials and the SoFEA trial should help to clarify its role in our armamentarium of hormonal therapies. The SoFEA trial will provide an indication of whether fulvestrant is better than exemestane as second-line therapy and also whether it's necessary to suppress the levels of estrogen. It's possible that by discontinuing the aromatase inhibitor, sufficient estrogen will be produced to circumvent the effects of fulvestrant. -- Anthony Howell, MD EFECT is an American and European study that will randomly assign patients who have failed therapy with a nonsteroidal aromatase inhibitor to fulvestrant or exemestane. Our own study, SoFEA, is slightly different from EFECT because it is based on the observation that the addition of small amounts of estrogen to cells that have been estrogen-deprived for a long time reduces the effectiveness of fulvestrant. That scenario equates to the withdrawal of a nonsteroidal aromatase inhibitor and the addition of fulvestrant. Hence, the third arm of our trial includes a nonsteroidal aromatase inhibitor and fulvestrant. The SoFEA trial will randomly assign 750 patients who have failed therapy with a nonsteroidal aromatase inhibitor to exemestane, fulvestrant alone or fulvestrant plus anastrozole. I predict fulvestrant alone will probably be better than exemestane, and fulvestrant plus anastrozole will be better than fulvestrant alone. -- Mitchell Dowsett, PhD.

Comments Regarding Article "Is This Any Way to Have a Baby?" by Barbara Seaman O Oprah ; Magazine February 2004 ASRM is not in the habit of commenting on individual articles that appear in the lay press. While ASRM does not always agree with a journalist's perspective, we generally respect the integrity of their reporting and appreciate their genuine efforts to inform their readers. However, after publication of the article "Is This Any Way to Have a Baby?" in the February issue of O Magazine, we felt compelled to express our profound objections to the misstatements and implications in this article. The article consists primarily of anecdotes from former infertility patients who either failed to become pregnant or had serious health issues during or following their infertility treatment. The manner in which these stories are presented implies that these tragic outcomes are common rather than the rare exception. The poorly researched reporting in this article can be appreciated from the citation of sources such as: "I talked to some women" and another as "A leading fertility scholar who prefers to remain anonymous said." No sincere effort is made to provide objectivity or to distinguish underlying medical problems that may be associated with but not caused by the infertility treatment. Therefore, ASRM believes that this particular situation warrants a response. Patients often feel victimized by and angry about their infertility condition, particularly when treatments fail or are associated with physical and emotional discomfort. Rather than to provide useful, factual information, this article serves merely to mislead and frighten already vulnerable women and undermine their trust in their healthcare providers. ASRM would expect that a reputable magazine such as "O" would welcome and accept correction constructive criticism. ASRM would therefore like to provide the following rebuttal to this article: 1. Fertility drugs cause cancer. The photographs of two deceased celebrities as the only two illustrations in the entire piece ; would imply that ovarian cancer is a common, proven side effect of ovulation medications. Certainly, the exceptional accomplishments of these women underscore the tragedy of their early deaths. However, this conjecture is unsupported by any scientific data; in fact, the preponderance of the medical literature that has addressed this subject to date has found that ovulation medications do not increase the risk of either ovarian or breast cancer. Women who have never been pregnant are at the greatest risk of developing ovarian cancer. It is therefore logical that infertility is also a risk factor for ovarian cancer. While it is an attractive theory that excessive ovarian stimulation might increase the risk, numerous studies have carefully scrutinized this possibility with none demonstrating an increased cancer incidence in patients exposed to infertility treatments. In fact, the Cochrane review cited by the author concludes that available data do not demonstrate a statistically significant increase in ovarian cancer associated with use of fertility medications. The author implies that breast cancer may also be increased by fertility medications. Whereas conditions associated with an increased lifetime exposure to estrogen increase the risk of breast cancer, no studies have indicated that the very short-term estrogen elevation produced by fertility treatment increases breast cancer incidence and

Relevance to the NHS Research and Development Programme The Department aims to use its resources to address clinically relevant questions. Of particular relevance to the NHS nationally is our work on predicting those patients with primary breast cancer about 35, 000 new cases each year in the UK ; who will benefit from tamoxifen treatment. About 80% of these patients will receive this drug immediately after surgery, often for more than five years, although only a minority will benefit see Apoptosis and Immunochemistry report ; . In addition, our work on the development of aromatase inhibitors over a 15-year period has helped identify drugs anwstrozole and letrozole ; , which are now being tested in international clinical trials involving over 15, 000 women. All these studies are rated of high or very high relevance to the NHS research and development programme.

To `puncture' condoms if they wanted to make a woman pregnant, and then as one informant said, `you'll get a disease or fall pregnant even if you were using a condom'. Only six informants said that they had ever used a condom. One explained that she sometimes used condoms with her partner whenever she suspected that he had another partner, adding that they openly did not always trust each other although she said she had always been sexually faithful ; , and that this situation was acceptable to both of them. Two informants had used condoms when the clinic had run out of Nuristerate, but one of these reported that `we didn't feel any desire' and stopped, and the other said that on one occasion they had sex without a condom because her partner told her he hadn't brought one and she became pregnant. Many informants who had never used condoms reported that they and their partners `trusted each other', and had no or few ; other sexual partners and so perceived themselves to be safe. Some said that they were reluctant to use them because of the potential problems, while others merely thought them to be `horrible'. A few admitted that they had never thought of using or that nurses had never offered them or explained what they were for. Some teenagers were evidently too disempowered within their sexual relationships to request or enforce condom use, despite general awareness that `diseases' could `spoil your reproductive organs', `affect' your womb and cause infertility if not treated early. One teenager for example described how her partner had refused to use condoms saying that `plastic' made him `sweat', and she hadn't challenged him because she feared that he would beat her. Another teenager reported that her partner had aggressively rejected her request that they use condoms, had demanded to know whether she had sex with other men, threatened to beat her and shouted at her that he would never `throw his blood away while looking at it'. In her words: `I told him about their importance, that there are many diseases and that he has many affairs but never tells me so he'll infect me'. Another informant made the point that women who wanted to prevent pregnancy had to use methods which they themselves could control as `boys force us to sleep with them without a condom even if we're not using contraception, and then obviously you can get pregnant'. Nurses reported that although they informed teenagers who had defaulted from a method to use condoms while waiting for their next menstruation, most teenage clients refused to take them because their partners would never agree to using them or because they were afraid to ask in case it would be misconstrued as an admission of sexual infidelity or mistrust. At most clinics however, nurses reported that some boys did come to request condoms usually in small groups ; and that there had been a visible increase in the numbers doing this since the campaigns.
Recent questions have been raised about the safety of these three widely used drugs.
Despite trials 20 and 21, most physicians start with anastrozole rather than fulvestrant because of the way the data have been presented.
Addition, tamoxifen provides a 47% reduction in contralateral breast cancer for patients with estrogen positive tumors. Tamoxifen therapy results in a slight increase in the incidence of endometrial cancer and thromboembolic events. In the EBCCTG overview, actual excess deaths from endometrial cancer in patients receiving tamoxifen was 2 deaths per 1000 patients. An increase in pulmonary embolus was also noted, with no increase in mortality. In addition, the benefit for combination chemotherapy and tamoxifen was additive.6 Tamoxifen, a selective estrogen receptor modulator SERM ; , is the current standard adjuvant hormone therapy for patients with estrogen receptor positive tumors. Aromatase inhibitors, which prevent the conversion of androgens to estrogens, are an effective therapy for postmenopausal women with advanced breast cancer. At the December 2001 San Antonio Breast Cancer Symposium, preliminary results of a clinical trial exploring the role of the aromatase inhibitor anastrozole trade name Arimidex ; in the adjuvant setting were presented. The trial, entitled Arimidex, Tamoxifen, Alone or in Combination ATAC ; , randomized patients who were candidates for adjuvant hormone therapy to 5 years of anastrozole, tamoxifen, or the combination. At a median duration of 3 years, patients receiving anastrozole had a significant reduction in disease-free survival compared to tamoxifen alone or the combination. In addition, the incidence of contralateral breast cancer was reduced significantly in patients receiving anastrozole compared to those randomized to tamoxifen. Longer follow-up is required to determine the effect of each therapy on disease-free survival, overall survival, and to determine the risk benefit of aromatase inhibitors on bone mineral density, endometrial cancer, incidence of new breast primaries and cognitive function. The ATAC trial is the single largest adjuvant trial ever conducted in women with early breast cancer, and enrolled 9, 366 postmenopausal women from 21 countries. Patient enrollment in clinical trials and completion of trials such as ATAC are crucial to answer outstanding questions in breast cancer treatment and prevention. The media portrayal of the ATAC preliminary results has raised anxiety for patients on.
This was the first randomized trial to compare the efficacy and tolerability of the new ER antagonist, fulvestrant, with tamoxifen for the treatment of postmenopausal women who have received no prior hormonal or cytotoxic therapy for advanced breast cancer. The results show fulvestrant to be active and well tolerated in this setting. Two large randomized trials have previously shown that fulvestrant is at least as effective as anastrozole against breast cancer in postmenopausal women who failed on prior endocrine therapy.8, 9 Naastrozole has previously demonstrated benefits over tamoxifen as first-line treatment for advanced disease, 13, 14 so it was considered probable that fulvestrant would also demonstrate benefits over tamoxifen in the first-line setting. It was therefore unexpected that fulvestrant showed neither superiority nor noninferiority to tamoxifen for the primary efficacy end point of TTP. The almost identical median TTP for fulvestrant and tamoxifen approximately 8 months ; in the subgroup of patients with ER and or PgR tumors the group intended for treatment with endocrine therapies ; indicates similar efficacy for the two treatments against hormone receptorpositive tumors. However, the upper 95% CI of the HR for TTP 1.36 ; in this subgroup does not rule out inferiority of fulvestrant compared with tamoxifen.
Hypoglycemia, or an insulin reaction, occurs from a relative excess of insulin in the blood and is characterized by belownormal blood glucose levels.38 It occurs most commonly in people treated with insulin injections, but prolonged hypoglycemia also can result from some oral hypoglycemic agents. Hypoglycemia usually has a rapid onset and progression of symptoms. The signs and symptoms of hypoglycemia can be divided into two categories: those caused by altered cerebral function and those related to activation of the autonomic nervous system. Because the brain relies on blood glucose as its main energy source, hypoglycemia produces behaviors related to altered cerebral function. Headache, difficulty in problem solving, disturbed or altered behavior, coma, and seizures may occur. At the onset of the hypoglycemic episode, activation of the parasympathetic nervous system often causes hunger. The initial parasympathetic response is followed by activation of the sympathetic nervous system; this causes anxiety, tachycardia, sweating, and constriction of the skin vessels i.e., the skin is cool and clammy ; . There is wide variation in the manifestation of signs and symptoms; not every person with diabetes manifests all or even most of the symptoms. The signs and symptoms of hypoglycemia are more variable in children and in elderly people. Elderly people may not display the typical autonomic responses associated with hypoglycemia but frequently develop signs of impaired function of the central nervous system, including mental confusion. Some people develop hypoglycemic unawareness. Unawareness of hypoglycemia should be suspected in people who do not report symptoms when their blood glucose concentrations are less than 50 to 60 mg dL. This occurs most commonly in people who have a longer duration of diabetes and A1C levels within the normal range.38 Some medications, such as -adrenergicblocking drugs, interfere with the sympathetic response normally seen in hypoglycemia. Many factors precipitate an insulin reaction in a person with type 1 diabetes, including error in insulin dose, failure to eat, increased exercise, decreased insulin need after removal of a stress situation, medication changes, and a change in insulin site. Alcohol decreases liver gluconeogenesis, and people with diabetes need to be cautioned about its potential for causing hypoglycemia, especially if it is consumed in large amounts or on an empty stomach. The most effective treatment of an insulin reaction is the immediate administration of 15 to glucose in concentrated carbohydrate source, which can be repeated as necessary. Monosaccharides such as glucose, which can be absorbed directly into the bloodstream, work best for this purpose. Complex carbohydrates can be administered after the acute reaction has been controlled to sustain blood glucose levels. It is important not to overtreat hypoglycemia and cause hyperglycemia. Alternative methods for increasing blood glucose may be required when the person having the reaction is.
