Fetal supraventricular tachycardia and maternal COVID-19 vaccination: is there any relationship?

Fetal supraventricular tachycardia accounts for 60-80% of the fetal tachyarrhythmias with prevalence ranging from 1/1000 to 1/25 000 pregnancies. It may be secondary to fetal anomalies or maternal factors. By reviewing the literature, there is no previous article that reports fetal arrhythmia after maternal vaccination.

Lateral distribution of endometriomas as a function of age.

The lateral asymmetry of ovarian endometriomas, with a left-sided predilection, seems to disappear with advancing age. This asymmetry does not seem to persist in women >35 years of age.

Pregnancy in patients with beta-thalassemia intermedia: outcome of mothers and newborns.

Little is known about the outcome of pregnancy in women with beta-thalassemia intermedia (TI). Over 10 years, maternal and neonatal outcomes of women with TI followed at a single thalassemia center were reviewed. Nine spontaneous pregnancies in five women with TI were studied.

The small-for-gestational-age twin: blessing or curse?

Objective: To compare small-for-gestational-age (SGA) twins to appropriate-for-gestational-age (AGA) twins regarding preterm delivery (PTD).

Study Design: Retrospective review of maternal and neonatal records of live, nonanomalous twins > or = 25 weeks' gestation delivered in 1984-2000 in a tertiary care center. Pregnancies (N = 679) were divided into AGA/ AGA (n = 347), SGA-AGA (n = 191) and SGA/SGA (n = 141) groups using singleton growth curves.

Pregnancy outcome in spontaneous twins versus twins who were conceived through in vitro fertilization.

Objective: The purpose of this study was to compare maternal and neonatal complications in spontaneous versus in vitro fertilization twins.

Study Design: Twin gestations that were delivered from 1995 to 2000 were reviewed. Cases consisted of 56 in vitro fertilization twins, each of which was matched to two control mothers by age and parity.
