Abstract
It is likely that mifepristone or levonorgestrel in the future will find extended use for contraceptive purposes. It is therefore essential to characterize the modes of action of these compounds. To assess the effect on the human Fallopian tube, 24 women with regular menstrual cycles and proven fertility, admitted to the hospital for voluntary sterilization by laparoscopic technique, were randomly allocated to a control or one of two treatment groups. Treatments were given with either a single dose of 200 mg mifepristone or 0.75 mg levonorgestrel in two doses 12 h apart, on day LH2. Surgery was performed on day LH4 to LH6. Steroid receptor expression was analysed by immunohistochemistry, Western blot and RT-PCR. In the controls, there was a higher concentration of progesterone receptors in the stromal cells in the isthmic region than in those in the ampullar region. Treatment with mifepristone increased the progesterone receptor concentration in epithelial and stromal cells and increased the estrogen receptor concentration in epithelial cells. No effect on steroid receptor concentration was found following levonorgestrel. The contraceptive effect of post-ovulatory mifepristone has previously been considered to be dependent on an effect on the endometrium. However an effect on the Fallopian tube could contribute to alter the peri-implantation milieu influencing fertilization and embryo development.

Abstract
Objectives:
To determine emergency department (ED) practitioner willingness to offer emergency contraception (EC) following sexual assault and consensual sex, and to compare responses of practitioners from states whose laws permit the refusal, discussion, counseling, and referral of patients for abortions (often called “opt-out” or “abortion-related conscience clauses”) with those of practitioners from states without these laws.

Methods: Using a structured questionnaire, a convenience sample of ED practitioners attending a national emergency medicine meeting was surveyed.

Results: The 600 respondents were: 71% male, 29% female; 34% academic, 26% community, and 33% resident physicians; and 7% nurse practitioners and physician assistants. Many respondents (88%) were inclined to offer EC to those sexually assaulted by unknown assailants. More practitioners said they were willing to offer EC if the assailant was known to be HIV-infected rather than if the assailant had low HIV risk factors (90% vs. 79%, p < 0.01). More respondents would prescribe EC after sexual assault than consensual sex (88% vs. 73%, p < 0.01). The rates of willingness to offer EC were the same for practitioners in states with “abortion-related conscience clauses” and those from other states.

Conclusions: Most ED practitioners said they were willing to offer EC. Although the risk of pregnancy exists after consensual sex, practitioners were less willing to prescribe EC after those exposures than for sexual assault. “Abortion-related conscience clauses” did not seem to influence willingness to offer EC.

The High Cost of Merging With A Religiously-Controlled Hospital

Conclusion

The trend of hospital mergers between religious and non-religious hospitals may continue to threaten access to reproductive health services, especially for patients who already have limited access because they live in rural areas or have low incomes.l” However, as this essay suggests, there are several avenues that concerned citizens and activists can take to try to prevent the loss of these vital services.l ” The creativity and determination of those who commit themselves to ensuring that reproductive health services will continue to be available to all who desire them has resulted in several viable legal and practical methods of intervention. Although I believe it is important to respect the religious rights and beliefs of others. when the expression of these beliefs encroaches on patients’ rights to access basic health services, intervention is appropriate and necessary. I hope that public outcry, in the forms of legal and grassroots action, will persuade state actors, legislatures, hospital administrators, and clergy to properly acknowledge patients’ rights and participate in the creation of acceptable solutions to the financial problems that hospitals increasingly face. We need solutions that do not deny essential health services to any group of people.

Extract
Following a Feb. 16 meeting with the Society of Obstetricians and Gynaecologists of Canada (SOGC) and 4 other organizations, Health Canada has started working toward making emergency postcoital contraception available without a prescription across the country . . . Senikas says some opponents equate EPC with abortion and “have this misplaced notion that emergency contraception is like RU-486. It’s not. It will never displace a pregnancy.

After Roman Catholic leaders issued strong criticism about its trampling of religious freedom, the American Medical Association approved a watered-down measure supporting continued community access to a full range of reproductive services following hospital consolidations. The AMA’s amended resolution stopped short of saying Catholic hospitals should have to perform all reproductive health procedures. . . The AMA instead upheld its policy that physicians and hospitals not be forced to perform services that violate their moral principles. . .

(News) With teen pregnancies skyrocketing, ob/gyns seek support for nonprescription “morning-after pill”

Support for a move to make emergency postcoital contraception available without a prescription appears to be mushrooming in Canada. The Society of Obstetricians and Gynaecologists of Canada (SOGC) and 23 other medical and pharmaceutical organizations have joined the groundswell of support since the SOGC launched a campaign to increase awareness and availability of the “morning-after pill” in November 1998. . . some CPhA members feel emergency contraception “may interfere with implantation of the fertilized egg and they consider that more [like] abortion,” said Cooper. Pharmacists for Life, a Canadian group with about 10 members, has already opposed the move, even though the World Health Organization (WHO) says taking the drug is not equivalent to performing an abortion because the woman is not pregnant.

Conscience clause: moral compromise

Chris Thatcher

Canadian Pharmacists Journal
Canadian Pharmacists Journal

Extract
Ask your pharmacist: It’s the ubiquitous slogan of the past decade, underscoring the campaigns of most national and provincial pharmacy organizations as they promote the value of pharmacy services. But what if the question is about RU-486, the abortion drug, or Preven, the morning-after-pill? What if the question is from a physician seeking information on terminal sedation or assisted suicide?

Such questions push, and often breach, an ethical boundary for some pharmacists, who find their desire to help the patient in conflict with their moral convictions. And the ethical quagmire is likely to get deeper as advocacy groups press the federal government to allow physician-assisted suicide and various health organizations promote greater access to emergency postcoital contraception.

If these practices compromise your moral convictions, could you be fired by your employer for refusing to fill a prescription? More specifically, is there a point at which your personal beliefs supersede your obligation to the patient? That’s the difficult question posed by an Alberta-based group called Concerned Pharmacists for Conscience, which has suggested a conscience clause to protect pharmacists in such situations.

Abortion: 1. Definitions and implications

Bernard M Dickens

Canadian Medical Association Journal, CMAJ
Canadian Medical Association Journal

Summary
Discusses the difference between definitions in the Criminal Code and regulations promulgated by provincial authorities. Notes that post-coital interception (IUD or pharmaceuticals) may be considered abortions. “The problem may become more acute when ‘morning-after’ contraception and menstrual self-regulation with pills and suppositories become widely available. Recent legislation in New Zealand has established that pregnancy begins not with fertilization but with implantation.6 To keep legitimate contraception from coming under the abortion law in Canada we should make a similar provision. However, the recommendation made in August 1980 by the general council of the United Church of Canada – to decriminalize abortion within the first 20 weeks of pregnancy – may be the best solution.”

Correction

[CMAJ] An error appeared in the editorial by Dr. Bernard M. Dickens in the Jan. 15, 1980 issue of the Journal. The second sentence in the second column should read (with the correction in italics): “Furthermore, if the life of the unborn child is deliberately ended after labour begins but before it has an existence outside the mother’s body, the act is considered child destruction, which is lawlul when it is done to save the mother’s life (section 221 [2]).” We apologize to Dr. Dickens for this oversight.

Since my earlier letter in the August 7 issue of the Journal, (p. 240) some additional information has been received which supports the use of the “morning after pill.” Sarrel at Yale reports only one pregnancy in about 1000 cases given 50 mg. of diethylstilbestrol daily for five days within 72 hours of unprotected intercourse.

Extract
A course of post-coital estrogens, in adequate dosage, is a highly effective and safe (though misnamed) form of post-coital contraception that deserves to be more widely known and prescribed. Both unwanted pregnancies and the demand for abortion could be reduced by its widespread use in emergency situations.
