This study aimed to determine the optimal cervical priming regimen before surgical abortion between 14+0 and 24+0 weeks\' gestation.
Embase, MEDLINE, and the Cochrane Library were searched for publications up to February 2020. Experts were consulted for any ongoing or missed trials.
Randomized controlled trials, published in English after 1985, that compared (1) mifepristone, misoprostol, and osmotic dilators against each other, alone or in combination; (2) different doses of mifepristone and misoprostol; (3) different intervals between priming and abortion; or (4) different routes of administration of misoprostol were included.
Risk of bias was assessed using the Cochrane Collaboration checklist for randomized controlled trials, and data were meta-analyzed in Review Manager 5.3. Dichotomous outcomes were analyzed as risk ratios using the Mantel-Haenszel method, and continuous outcomes were analyzed as mean differences using the inverse variance method. Fixed effects models were used when there was no significant heterogeneity (I2<50%), random effects models were used for moderate heterogeneity (I2≤50% and <80%), and evidence was not pooled when there was high heterogeneity (I2≥80%). Subgroup analyses were undertaken based on parity where available. The overall quality of the evidence was assessed using Grades of Recommendation Assessment, Development, and Evaluation.
A total of 15 randomized controlled trials (N=2454) were included and showed decreased difficulty of procedure and/or increased cervical dilation and decreased patient acceptability with regimens that included dilators compared with those that did not include dilators; increased preoperative expulsion of the pregnancy with sublingual misoprostol and mifepristone compared with sublingual misoprostol alone; increased difficulty of procedure with dilators and misoprostol compared with dilators and mifepristone; decreased difficulty of procedure with dilators and mifepristone compared with dilators alone; and increased cervical dilation when dilators were placed the day before abortion compared with the same day.
Considered alongside clinical expertise, the published data support the use of osmotic dilators, misoprostol, or mifepristone before abortion for pregnancies at 14+0 to 16+0 weeks\' gestation; osmotic dilators or misoprostol for pregnancies at 16+1 to 19+0 weeks\' gestation; and osmotic dilators alone or with mifepristone for pregnancies at 19+1 to 24+0 weeks\' gestation. The effectiveness of pharmacologic agents alone beyond 16+0 weeks\' gestation and the optimal timing of dilator placement remain important questions for future research.

This study aimed to determine the optimal cervical priming regimen before surgical abortion up to and including 13+6 weeks\' gestation.
Embase, MEDLINE, and the Cochrane Library were searched for publications up to February 2020. Experts were consulted for any ongoing or missed trials.
This study included randomized controlled trials published in English after 2000 that compared the following: (1) mifepristone and misoprostol against each other, placebo, or no priming; (2) different doses of mifepristone or misoprostol; (3) different intervals between priming and abortion; or (4) different routes of misoprostol administration.
Risk of bias was assessed using the Cochrane Collaboration checklist for randomized controlled trials, and data were metaanalyzed in Review Manager 5.3. Dichotomous outcomes were analyzed as risk ratios using the Mantel-Haenszel method, and continuous outcomes were analyzed as mean differences using the inverse variance method. Fixed effects models were used when there was no substantial heterogeneity (I2<50%), random effects models were used for moderate heterogeneity (I2≤50% and <80%), and evidence was not pooled when there was high heterogeneity (I2≥80%). Subgroup analyses were undertaken based on parity where available. The overall quality of the evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation.
A total of 18 randomized controlled trials (n=8538) were included and showed the following: decreased incomplete abortion rate (risk ratio=0.44; 95% confidence interval, 0.21-0.9) and force required to dilate the cervix (mean difference= -7.08 N; 95% confidence interval, -11.67 to -2.49) and increased preoperative bleeding (risk ratio=5.90; 95% confidence interval, 5.08-6.86) with misoprostol compared with no priming; decreased preoperative bleeding when sublingual misoprostol was given 1 hour before abortion compared with 3 hours before (risk ratio=0.14; 95% confidence interval, 0.03-0.56); and increased force required to dilate the cervix (mean difference=14.3 N; 95% confidence interval, 2.13-26.47) when mifepristone was given 24 hours before abortion compared with 48 hours before. The quality of the evidence base was limited by low event rates and risk of bias in included studies.
Cervical priming with misoprostol decreases the force needed to dilate the cervix for first trimester surgical abortion and reduces the risk of incomplete abortion. Considered alongside clinical expertise, this evidence supports the use of routine cervical priming before first trimester surgical abortion with 400 µg misoprostol or, if misoprostol cannot be used, 200 mg oral mifepristone.

Evidence-based guidelines on the management of pain associated with first-trimester medical abortion are lacking. Most published clinical trials have failed to report on this important aspect of the procedure. The aim of this comprehensive work was to provide clinical advice based on a comprehensive literature review, supplemented by the clinical experience of a group of European experts in case no evidence is available. Pain level ranged from 5 to 8 in 80% of studies where pain was measured on a 0-10 visual analogue scale; severe pain was reported by 20-80% of women. Pain assessment was rarely reported in studies. Pain treatment should be preventive and avoidance of unnecessary uterine contractions should be considered. Analgesic treatment should follow the WHO three-step ladder, starting with the use of NSAIDs and allowing for easily available back-up treatment with weak opioids.

After years of the worsening burden of unsafe abortion and attendant morbidities and mortalities in Nigeria, a National Guideline on the Safe termination of pregnancy for legal indications was enunciated. This report presents and discusses an illustrative case of a hydranencephaly that benefited from it. A 43-year old multipara was informed during routine ultrasonography at booking for antenatal care, at 16 weeks of gestation, of a major defect in her baby and advised to meet her physician. Following a repeat high- resolution ultrasonography and discussions between the Obstetricians, Neurosurgeon, and Ultrasonologist, the woman was counseled on the diagnosis. At her insistence and provision of written consent, medical abortion with Mifepristone and Misoprostol was successfully instituted.

OBJECTIVE: The objective of this work is to evaluate the place of new treatments in the management of endometriosis outside the context of infertility.
METHODS: A review of the literature was conducted by consulting Medline data until July 2017.
RESULTS: Dienogest is effective compared to placebo in short term (NP2) and long term (NP4) for the treatment of painful endometriosis. In comparison with GnRH agonists, dienogest is also effective in terms of decreased pain and improved quality of life in non-operated patients (NP2) as well as for recurrence of lesions and symptomatology postoperatively (NP2). Data on GnRH antagonists, selective progesterone receptor modulators as well as selective inhibitors (anti-TNF-α, matrix metalloprotease inhibitors, angiogenesis growth factor inhibitors) are insufficient to provide evidence of interest in clinical practice for the management of painful endometriosis (NP3).
CONCLUSIONS: Dienogest is recommended as second-line therapy for the management of painful endometriosis (Grade B). Because of lack of evidence, aromatase inhibitors, elagolix, SERM, SPRM and anti-TNF-α are not recommended for the management of painful endometriosis (Grade C).

To analyze the success rate, time to passage of tissue and subjective patient experience of a newly implemented protocol for medical management of early pregnancy failure (EPF) over a 2-year period.
A retrospective chart review of all patients with early pregnancy failure primarily opting for medical management was performed. 200 mg mifepristone were administered orally, followed by a single vaginal dose of 800 mcg misoprostol after 36-48 h. We followed-up with our patients using a written questionnaire.
167 women were included in the present study. We observed an overall success rate of 92 %, defined as no need for surgical management after medication administration. We could not identify predictive values for success in a multivariate regression analysis. Most patients (84 %) passed tissue within 6 h after misoprostol administration. The protocol was well tolerated with a low incidence of side effects. Pain was managed well with sufficient analgesics. Responders to the questionnaire felt adequately informed prior to treatment and rated their overall experience as positive.
The adaption of the institutional medical protocol resulted in a marked improvement of success rate when compared to the previously used protocol (92 vs. 61 %). We credit this increase to the adjusted medication schema as well as to targeted physician education on the expected course and interpretation of outcome measures. Our results underscore that the medical management of EPF is a safe and effective alternative to surgical evacuation in the clinical setting.

For a dilation and evacuation (D&E) procedure, the cervix must be dilated sufficiently to allow passage of operative instruments and products of conception without injuring the uterus or cervical canal. Preoperative preparation of the cervix reduces the risk of cervical laceration and uterine perforation. The cervix may be prepared with osmotic dilators, pharmacologic agents or both. Dilapan-S™ and laminaria are the two osmotic dilators currently available in the United States. Laminaria tents, made from dehydrated seaweed, require 12-24 h to achieve maximum dilation. Dilapan-S™, made of synthetic hydrogel, achieves significant dilation within 4 h and is thus preferable for same-day procedures. A single set of one to several dilators is usually adequate for D&E before 20 weeks\' gestation. Misoprostol, a prostaglandin E1 analogue, is sometimes used instead of osmotic dilators. It is generally regarded as safe and effective; however, misoprostol achieves less dilation than overnight osmotic tents. The literature supports same-day cervical preparation with misoprostol or Dilapan-S™ up to 18 weeks\' gestation. As the evidence regarding alternative regimens increases, highly experienced D&E providers may consider same-day regimens at later gestations utilizing serial doses of misoprostol or a combination of osmotic and pharmacologic agents. Misoprostol use as an adjunct to overnight osmotic dilation is not significantly beneficial before 19 weeks\' gestation. Limited data demonstrate the safety of misoprostol before D&E in patients with a prior cesarean delivery. Mifepristone, a progesterone receptor antagonist, is also effective for cervical preparation prior to D&E, although data to support its use are limited. The Society of Family Planning recommends preoperative cervical preparation to decrease the risk of complications when performing a D&E. Since no single protocol has been found to be superior in all situations, clinical judgment is warranted when selecting a method of cervical preparation.

There are still too many unsafe abortions performed worldwide. Together with the efforts to reduce the abortion by choice, we note a rise in the need for mid trimester pregnancy termination for medical reasons. The article looks at the past present and future perspective of the abortion as a procedure in Bulgaria. States the fact that medical abortion is officially not widely performed. We reckon that with the existing guidelines by WHO and with Mifepriston and Misoprostol recently registered in Bulgaria, it is time for the medical abortion to become part of the clinical practice in Bulgaria. We believe that early medical abortion as well as mid trimester induced abortion is and adequate if not better alternative to the existing in Bulgaria procedures.

The need to interrupt a pregnancy between 24 and 28 weeks of gestation is uncommon and is typically due to fetal demise or lethal anomalies. Nonetheless, treatment options become more limited at these gestations, when access to surgical methods may not be available in many circumstances. The efficacy of misoprostol with or without mifepristone has been well studied in the first and earlier second trimesters of pregnancy, but its use beyond 24 weeks\' gestation is less well described. This document attempts to synthesize the existing evidence for the use of misoprostol with or without mifepristone to induce labor for nonviable pregnancies at gestations of 24-28 weeks. The composite evidence suggests that a regimen combining mifepristone and misoprostol may shorten the time to expulsion, though the overall success rates are similar to those seen with misoprostol-only regimens.
