Objectives: Recurrent miscarriages are a current consultation pattern. Etiologic evaluation is classically proposed and preventive therapy should be discussed. We wanted to study our University Hospital pregnancies outcomes, following 3 repetitive early miscarriages, and how those patients are managed., Materials and Methods: A 10-years retrospective study has been performed in our center, with 296 patients found having a three-repetitive miscarriage experience. Information about diagnostic evaluation following miscarriages, preventive therapy initiation, and next pregnancy outcome has been provided., Results: Around 62.5% of the patients experienced a life-birth. When investigations were done (n=148), a 64.9% part of the patients had abnormal results. Life-birth rate was more important when there were normal karyotypes or no thrombophilia found (respectively p equal 0.30 and 0.45). We noticed a better prognostic in the group of patients with normal investigations results who had a preventive therapy (n=20, 85% of life-birth, P=0.19)., Conclusion: When done, investigations for recurrent miscarriages, allow the finding of an abnormality in two thirds of cases. Wonderingly, outcomes are very encouraging since that almost two thirds of the patients experienced life-birth. Investigations indications, results interpretations, and consecutive therapy should be well thought but preventive therapy seems to be efficient in the normal results patient group., (Copyright © 2014 Elsevier Masson SAS.

The files for ultrasound diagnosis of gestating mares belonging to the French equine herd recorded for 3 consecutive years were joined with the files for foal birth of these same mares, allowing the statistical analysis of factors of pregnancy loss. For 28 872 positive diagnoses of gestation, 2898 losses were recorded, that is, a global rate of gestation interruption of 9.12%. The etiology of these interruptions is mainly extrinsic: the year and month of insemination, as well as region for climatic reasons. The intrinsic causes that are implicated are breed of the father (heavy breeds except the hypermetric ones lose fewer pregnancies than warm-blooded breeds), age of the mother (losses are lower in mares of 7 to 10 years of age) and status (mares with foals have fewer pregnancy losses than mares not having foaled the previous year), as well as fetuses with consanguinity (when this increases, the pregnancy losses increase as well). However, the additive genetic effect is extremely low; it corresponds to heritability below 5% and few effects of the environment, common to the offspring of the same mare, were identified. This therefore gives little hope of being able to select against the 'gestation loss' trait.

Vanishing fetal twins occurred in 9% (264 out of 2,829) intracytoplasmic sperm injection pregnancies and are associated with a lower fetal loss rate in the first trimester. The live birth rate was higher in pregnancies associated with vanishing fetuses., (Copyright © 2010 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.)

The aim was to compare obstetric outcomes of IVF singleton pregnancies diagnosed with vanishing twin (VT) syndrome with those pregnancies originating as singleton pregnancies and with twin pregnancies. In this case control study, 57 patients diagnosed with VT syndrome were matched and compared with 171 singleton controls and 171 twin controls. Mean gestational age was 35.1+/-3.7 versus 38.2+/-2.6 weeks (P=0.001) for patients and singleton controls respectively. Birth weights were 2834.4+/-821.2 versus 3036+/-489.3g (P=0.02), proportion of low birth weight (< 2500 g) was 33.3 versus 11.7% (P=0.0001) and very low birth weight (< 1500 g) 3.5 versus 0.6% for patients and singleton controls respectively. The proportion of deliveries before 28 weeks of gestation was 7.0 versus 1.2% (P=0.01) for patients and singleton controls respectively. When comparing the study group to twin control pregnancies, a similar gestational age at delivery (35 weeks) and rate of preterm birth (23%) were found. In conclusion, pregnancies diagnosed with the VT syndrome after IVF carry a higher rate of adverse obstetric outcomes in terms of preterm deliveries and lower birth weight, compared with IVF pregnancies that were originally singleton. Additionally, significant similarities were observed in the obstetrics outcome of vanishing twin pregnancies and twin pregnancies., (2009 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

An observational study including 276 patients with early pregnancy failure was performed to evaluate the clinical and ultrasound factors influencing the efficacy of misoprostol in the treatment of first trimester pregnancy failure. Gestational age did not influence the efficacy of this treatment and the success rate was inversely proportional to parity.
