To determine whether ultrasonographic findings can predict the karyotype of spontaneous abortions, 137 pregnancies (54 spontaneous, 83 assisted ovulatory cycles) that subsequently aborted and had chromosome analysis performed on the products of conception were studied ultrasonographically. Transvaginal ultrasound was performed using an Acuson 128XP/10 with 7.5 MHz probe. The numbers of empty ge...

objective: approximately 15-20% of clinically recognizable pregnancies end in spontaneous abortion. the incidence of chromosomal abnormalities in those abortions is as high as 50%.a modest but clinically important proportion of spontaneous abortions is caused by a balanced chromosomal aberration in one of the parents. this results from the production of gametes and embryos with unbalanced chrom...

objective: this study determined the chromosomal constitution of recurrent spontaneous abortions by comparative genomic hybridization (cgh) analysis of fetal samples. material and methods:   forty pregnant women with early recurrent pregnancy losses aged 21 to 42 years old from tehran university of medical sciences affiliated hospitals entered in this descriptive study. hibridization analysis o...

Data on the birth ranks of miscarriages within sibships in which a case of anencephaly or spina bifida (ASB) had occurred were analysed by the Haldane-Smith statistical test. This showed that miscarriages in ASB sibships tend to have a negative birth order effect--that is, they occur in earlier rather than later pregnancies within the sibship. The strongest source of bias in this analysis--the ...

KEY II X Deadinferred carrier Q Chromosomes normal a couple who presented at a sub-fertility clinic with a history of two spontaneous abortions and no live born children after three years of marriage. Examination revealed a healthy 23-year-old female and a 27-year-old male, neither of whom had any previous relevant medical history. In addition to the two original spontaneous abortions, at 8 and...

The toxicity of pesticides on human reproduction is largely unknown--particularly how mixtures of pesticide products might affect fetal toxicity. The Ontario Farm Family Health Study collected data by questionnaire on the identity and timing of pesticide use on the farm, lifestyle factors, and a complete reproductive history from the farm operator and eligible couples living on the farm. A tota...

1. Abdella A. 1996. Demographic characteristics, socioeconomic profile and contraceptive behaviour in patients with abortion at Jimma Hospital, Ethiopia. East Afr Med J. Vol. 73(10): 660-664. • This is a hospital-based study of women admitted for post-abortion care (PAC) in 1992-1993. 53% of the cases were induced abortions (using the WHO definition of “definite induced”) while 47% were spontan...

The authors estimated the number of clinically recognized pregnancies that occurred annually from 1981 to 1991 in the United States by type of outcome and by race. Estimates of the numbers of livebirths, induced abortions, ectopic pregnancies, and fetal deaths were obtained by using data from the Centers for Disease Control and Prevention in Atlanta, Georgia. The number of spontaneous abortions...
