RESUMEN
OBJECTIVE: To describe the prevalence of labour induction, together with its risk factors and outcomes in Latin America. DESIGN: Analysis of the 2005 WHO global survey database. SETTING: Eight selected Latin American countries. POPULATION: All women who gave birth during the study period in 120 participating institutions. METHODS: Bivariate and multivariate analyses. MAIN OUTCOME MEASURES: Indications for labour induction per country, success rate per method, risk factors for induction, and maternal and perinatal outcomes. RESULTS: Of the 97,095 deliveries included in the survey, 11,077 (11.4%) were induced, with 74.2% occurring in public institutions, 20.9% in social security hospitals and 4.9% in private institutions. Induction rates ranged from 5.1% in Peru to 20.1% in Cuba. The main indications were premature rupture of membranes (25.3%) and elective induction (28.9%). The success rate of vaginal delivery was very similar for oxytocin (69.9%) and misoprostol (74.8%), with an overall success rate of 70.4%. Induced labour was more common in women over 35 years of age. Maternal complications included higher rates of perineal laceration, need for uterotonic agents, hysterectomy, ICU admission, hospital stay>7 days and increased need for anaesthetic/analgesic procedures. Some adverse perinatal outcomes were also higher: low 5-minute Apgar score, very low birthweight, admission to neonatal ICU and delayed initiation of breastfeeding. CONCLUSIONS: In Latin America, labour was induced in slightly more than 10% of deliveries; success rates were high irrespective of the method used. Induced labour is, however, associated with poorer maternal and perinatal outcomes than spontaneous labour.

The values of the medical profession and other healthcare providers allow assessment of the relationship between physicians, healthcare teams, patients, and healthcare networks regarding the defense and promotion of sexual and reproductive health and rights. This paper questions the traditional model of the relationship between healthcare professionals and patients, based on the classic paternalistic role of the physician. It describes the tools available to the medical profession and healthcare teams for the promotion of sexual and reproductive rights, and proposes specific actions that would lead to improvements for women and communities.

Induction of labor is common in clinical practice. Many different medical and mechanical methods have been used, but the current gold standard is vaginal dinoprostone. Misoprostol has been used for the induction of labor since 1987. In early studies with large misoprostol doses (e.g. 200 microg) there were high rates of uterine hyperstimulation. Cochrane meta-analysis, however, shows that when used in low doses it is as effective as vaginal dinoprostone and with no excess of hyperstimulation. 25 microg vaginal misoprostol 4-hourly, 50 microg oral misoprostol 4-hourly or 20 microg oral misoprostol solution 2-hourly are all safe and effective regimens. Reports of uterine rupture in women with previous cesarean sections mean that it remains contraindicated in this group.

The aim was to review the current knowledge about the use of misoprostol alone for abortion induction during the first 12 weeks of pregnancy. Publications reporting experiences with misoprostol alone for pregnancy termination within the first 12 weeks of pregnancy were included in the analysis. Vaginal administration of 800 microg repeated up to three times at 6, 12 or 24 h intervals has an 85% to 90% effectiveness, defined as complete abortion, in most studies. Oral administration is less effective, but sublingual administration at 3-hour interval has the same effectiveness, with more frequent side effects. The oral and sublingual routes appear to be better accepted than vaginal administration. Most studies are limited to the first 9 weeks of pregnancy. The experience on pregnancy termination between 10 and 12 weeks is not yet sufficient for a recommendation.

Emergency contraception (EC) is safe and has the potential to prevent unwanted pregnancies. However, use remains low in most settings, due to a range of barriers to access. This paper reviews key issues related to EC and describes recommendations reached during the Women's Health Alliance pre-Congress workshop, held in advance of the FIGO 2006 World Congress. The working group concluded that national societies of obstetrics and gynecology can play an important role in increasing access to this unique contraceptive method.

BACKGROUND: Levonorgestrel (LNG) consistently prevents follicular rupture only when it is given before the onset of the ovulatory stimulus. As locally synthesized prostaglandin (PG) plays a crucial role in follicular rupture and cyclooxygenase-2 (cox-2) catalyses the final step of PG synthesis, we reasoned that adding a cox-2 inhibitor to LNG would prevent follicular rupture even after the ovulatory process had been triggered by the gonadotrophin surge. METHODS: Forty-one women were divided into two groups. One was treated when the size of the leading follicle was 15-17 mm (n=10) and the other when it was >or=18 mm (n=31). Each woman contributed with one cycle treated with LNG 1.5 mg single dose plus placebo and another treated with LNG + meloxicam (Melox) 15 mg, in a randomized order. Serial blood sampling for the assay of LH and follicular monitoring by transvaginal ultrasound were performed before and after treatment. RESULTS: Follicular rupture failed to occur within the 5-day period that followed treatment in 50 and 70% of cycles treated with LNG + Placebo and LNG + Melox, respectively, in the 15-17 mm group (P=0.15) and in 16 and 39% of cycles treated with LNG + Placebo and LNG + Melox, respectively, in the >or=18 mm group (P < 0.052). The overall proportion of cycles with no follicular rupture or ovulatory dysfunction increased significantly by the addition of Melox to LNG (66 versus 88%, P < 0.012; n=41-matched pairs). CONCLUSIONS: The trend towards increased incidence of no follicular rupture when Melox was combined with LNG suggests that the addition of a cox-2 inhibitor has the potential to improve the contraceptive efficacy of LNG by a pre-fertilization effect.

INTRODUCTION: Worldwide, 13% of maternal deaths are caused by complications of spontaneous or induced abortion, 29% in Uruguay and nearly half (48%) in the Pereira Rossell Hospital. PURPOSE: This paper describes a risk reduction strategy for unsafe abortions in Montevideo, Uruguay, where over one-fourth of maternal deaths are caused by unsafe abortion. METHODS: Although abortion is not legal in Uruguay, women desiring abortions can be counseled before and immediately after to reduce the risk of injury. Women contemplating abortion were invited to attend a "before-abortion" and an "after-abortion" visit at a reproductive health polyclinic. At the "before-abortion" visit, gestational age, condition of the fetus and pathologies were diagnosed and the risks associated with the use of different abortion methods (based on the best available scientific evidence) were described. The "after-abortion" visit allowed for checking for possible complications and offering contraception. RESULTS: From March 2004 through June 2005, 675 women attended the "before-abortion" and 495 the "after-abortion" visit, the number increasing over time. Some women (3.5%) decided not to abort, others were either not pregnant, the fetus/embryo was dead or the woman had a condition that permitted legal termination of pregnancy in the hospital (7.5%). Most women, however, aborted. All women used vaginal misoprostol in the doses recommended in the medical literature. There were no serious complications (one mild infection and two hemorrhages not requiring transfusion). CONCLUSION: The strategy is effective in reducing unsafe abortions and their health consequences.

We assessed to what extent the standard dose of levonorgestrel (LNG), used for emergency contraception, or a single dose (half dose), given in the follicular phase, affects the ovulatory process during the ensuing 5-day period. Fifty-eight women were divided into three groups according to timing of treatment. Each woman contributed with three treatment cycles separated by resting cycles. All received placebo in one cycle, and standard or single dose in two other cycles, in a randomized order. The diameter of the dominant follicle determined the time of treatment. Each woman had the same diameter assigned for all her treatments. Diameters were grouped into 33 categories: 12-14, 15-17 or 18-20 mm. Follicular rupture failed to occur during the 5-day period in 44%, 50% and 36% of cycles with the standard, half dose and placebo, respectively. Ovulatory dysfunction, characterized by follicular rupture associated with absent, blunted or mistimed gonadotropin surge, occurred in 35%, 36% and 5% of standard, single dose or placebo cycles, respectively. In conclusion, LNG can disrupt the ovulatory process in 93% of cycles treated when the diameter of the dominant follicle is between 12 and 17 mm. It is highly probable that this mode of action fully accounts for the contraceptive efficacy as well as the failure rate of this method. The present data suggest that half the dose may be as effective as the standard dose.

The aim of this paper is to describe different approaches to make emergency obstetric care (EmOC) accessible to women in Mozambique. The definitions of basic (BEmOC) and comprehensive EmOC (CEmOC), proposed by the UN agencies, were adopted by FIGO and by the Mozambican Ministry of Health as a general strategy to reduce maternal mortality. Four projects are presented: (1) José Macamo and (2) Mavalane Hospitals in Maputo city, (3) Manhiça District in Maputo Province and (4) Sofala Province. José Macamo was staffed by physicians 24 h a day; other hospitals by non-physicians trained in surgical and anesthesiology techniques, as well as nurse-midwives. José Macamo Hospital provided CEmOC to the city of Maputo and the southern area of Maputo Province. In 2001, this hospital attended 32% of deliveries and 38% of cesarean sections in the city, up from 14 and 2.5%, respectively, in 1998. The Mavalane Hospital failed to provide CEmOC; however, the number of deliveries per year almost doubled. The Manhiça hospital carried out 31% of the District's C-sections in 2001, up from 9% in 1998. In Sofala Province, one additional CEmOC and four BEmOCs were installed and case fatality rates decreased. In conclusion, the strategy for ensuring provision of EmOC is feasible even in countries with minimal resources and a scarcity of physicians, such as Mozambique.

The prevalence of local signs and symptoms related to the site of insertion of implants, and the association of these signs and symptoms with time of use, skin color and body mass index (BMI) was evaluated among users of the Norplant implant system. Three hundred and three Norplant users attending at the reproductive health clinic of PROFAMILIA in Santo Domingo, Dominican Republic, were asked if they had ever had any discomfort at the site/arm of implant insertion and the implant insertion area was examined and hyperpigmentation and hollowing of the surface was recorded. Half of the subjects reported either pain or paresthesia or both, in almost equal numbers, some time since insertion. Hyperpigmentation was observed in 35.6% and hollowing in 22.4% of the subjects. Report of pain and paresthesia was inversely associated to time of use and to BMI. Hyperpigmentation was directly associated to time of use and darker skin, and hollowing of the arm surface in the implants area with time of use and BMI. Local signs and symptoms were more frequent than previously reported, although they were of mild nature and appeared not to worry most of the users.

Emergency contraception (EC) consists of either 1.5 mg of levonorgestrel (LNG) in one or two doses, or a combination of LNG with ethinylestradiol, administered for up to 5 days after unprotected intercourse. Clinical studies indicate that LNG alone is more effective and has less side effects. Its effectiveness decreases the longer after coitus it is taken. EC is indicated when there is non-compliance or accidents with the use of regular methods of contraception, or when women have had voluntary or imposed unprotected intercourse. The ethics of providing EC has been questioned by some, arguing that it acts by preventing implantation. Scientific evidence does not support this concept, but shows that EC acts mostly before fertilization. Placing obstacles to the access of EC is unethical as it transgresses the ethical principles of autonomy, non-maleficence beneficence and justice. Far from inducing abortions, EC reduces unwanted pregnancies and prevents abortion.

Contraceptive implant technology has been used by millions of women throughout the world. The three marketed implant systems today are levonorgestrel-releasing implants: Norplant and Jadelle, and a single etonogestrel-releasing implant, Implanon. The main benefits common to these delivery systems are their safety, high effectiveness, ease of use, long duration of action (3 - 5 years) and reversibility. Bleeding disturbances are the main adverse events associated with implantable contraceptives. Other minor risks relate to the insertion and removal procedures, which require adequately trained providers as well as aseptic techniques. Furthermore, since initiation and discontinuation of use is provider-dependent and not controlled by the user, there may be a risk of coercion of use on the one hand or, on the other hand, difficulty in access to initiating use, if trained providers are not readily available. Although no single contraceptive method is perfect or appealing to all, contraceptive implants are safe and fulfil a very important need among fertility regulation methods.

The objective of the study was to evaluate the effect of levonorgestrel (LNG) on the occurrence of acrosome reaction (AR) of capacitated spermatozoa from fertile men. A total of 20 semen samples from four fertile men were evaluated. The spermatozoa were separated by swim-up, and subsequently incubated for 20 h under capacitating conditions. Capacitated spermatozoa were exposed to three different concentrations of LNG (200, 400 and 800 ng/mL), follicular fluid (20% v/v), and ethanol or human tubal fluid medium (HTF) as a control. The AR rate and the ratio of live to dead spermatozoa were assessed after 15 and 30 min of incubation at 37 degrees C and 5% CO(2). The different treatments were compared with follicular fluid and HTF medium as positive and negative controls. The main results showed that the AR rate after 15 min of exposure was not affected by LNG and was significantly higher with follicular fluid than with all the other treatments. At 30 min of exposure, the three LNG concentrations induced a greater rate of AR than the HTF and a trend of higher AR rate with greater concentration was observed. Follicular fluid induced a significantly higher rate of AR than the other treatments. In conclusion, the addition of LNG in vitro to capacitated human spermatozoa is associated with a dose-dependent increased rate of AR, but such increase was not as great that induced by follicular fluid.

Ectopic or tubal pregnancy presents a medical emergency that requires prompt treatment in order to contain risks of maternal death and morbidity, including loss of future fertility. Medical circumstances involving individual patients and resources of the prevailing health care system will determine the options and means of treatment. Termination of ectopic pregnancy does not constitute or directly implicate abortion. Any practice of deliberately delaying treatment of reliably diagnosed ectopic pregnancy, on non-clinical grounds, until rupture of the fallopian tube has occurred or is imminent, in order to justify termination of the ectopic pregnancy on grounds of saving the patient's life, is unethical and illegal. Those who undertake or counsel deliberate delay of medically-indicated treatment can be charged with criminal offences and civil (non-criminal) liability, and medical professional misconduct. On reliable diagnosis, prompt treatment to remove ectopic pregnancy is legally justified, and ethically and legally required.

The aim of this study was to compare the urodynamic findings among climacteric women complaining of urinary incontinence who had only vaginal deliveries with those who had only cesarean sections. The study group comprised 30 climacteric women with complaints of urinary incontinence consulting at the Menopause Outpatient Clinic, State University of Campinas, submitted to anamneses and complete urodynamic testing. Nineteen women had had only vaginal deliveries and 11 were delivered only by cesarean section. Vaginal delivery was significantly associated with a reduced normal and strong desire to void and maximum cystometric capacity compared to women who delivered only by Cesarean section. Detrusor instability was four to five times more frequent among women who had had only vaginal deliveries. There was no difference between the two groups concerning uroflowmetry parameters. Climacteric women with urinary incontinence who had had only vaginal deliveries are at a higher risk of urodynamic abnormalities.

Sexual violence is highly prevalent although barely visible in most countries. While its prevention is a task of the whole society, the care of the women who suffer sexual violence, from immediate assistance to treatment of its consequences, is a responsibility of obstetricians-gynecologists. One of the most severe consequences of rape is unwanted pregnancy, which frequently ends in abortion. Currently, even in countries where abortion following rape is accepted by the law, raped women do not have access to legal abortion. The role of obstetricians-gynecologists in solving this problem is described, giving as an example the work of the Brazilian Federation of Gynecology and Obstetrics Societies (FEBRASGO). After 5 years of work of a special FEBRASGO Committee, services for the comprehensive care of women victims of sexual violence exist in all mayor cities in Brazil and are rapidly expanding.

This study was conducted to assess to what extent the Yuzpe regimen, or half the dose, given in the follicular phase, prevents ovulation during the ensuing 5 days. Sixty women were divided into six groups. All groups received placebo in one cycle and drug in another, in a randomized order. Groups differed by the dose and size of the leading follicle at the time of treatment (12-14, 15-17, or 18-20 mm). Ovulation was absent during the ensuing 5 days in 13 of 20 participants (65%) and in 8 of 20 participants (40%) who received the full and the half dose, respectively, when follicles were 12-17 mm. No ovulation occurred, within the critical period, in 7 of 39 placebo cycles (18%). When follicles were 18-20 mm, treatment did not prevent ovulation. In most drug-treated cycles, plasma gonadotropin and sex steroid levels were significantly depressed within the 5-day period, even when follicular rupture occurred within that period. In conclusion, the Yuzpe regimen can suppress or postpone ovulation to an extent that exceeds the fertile life of spermatozoa. Lack of ovulation within the critical period and dysfunction of the ovulatory process probably account for the contraceptive effect of this method in most cases. The present data do not warrant the use of half the dose of the Yuzpe regimen.

Contraceptive methods, including implants, do not prevent common symptoms and adverse health events that most people experience. It is difficult, therefore, to decide whether or not the occurrence of symptoms or adverse events that are common can be attributed to use of a contraceptive method or to determine if a given method changes the likelihood of their occurrence. Based on the review of the literature, no apparent differences in the frequency of adverse events are evident between the six-implant or two-rod levonorgestrel systems and the single implant etonogestrel and nomegestrol acetate systems. The most frequent adverse events reported in clinical trials that are probably related to implant use are headaches and acne. Weight gain, dizziness, and mood changes are also frequently mentioned adverse events and are possibly steroid-related. Other possibly related adverse events, although much less frequently reported, are loss of libido, fatigue, hair loss, and other skin conditions. Persistent ovarian follicles that spontaneously disappear are a common event during use of progestin-only contraceptives, and providers should be aware of this condition to avoid unnecessary interventions. Overall, the vast experience reported in the clinical studies reviewed here show that all existing implantable contraceptives are equally safe. This can probably be attributed to the low-hormonal dose delivered by progestin-implant systems.
