The story of her allegedly stolen twin brother in Armenia is recounted by a 'singleton twin' living in the United States. The behavioral consequences and societal implications of this loss are considered. This case is followed by twin research reports on the evolution of sleep length, dental treatment of craniopagus conjoined twins, cryopreserved double embryo transfer (DET), and gender options...

We report neurologic damage in twins that was associated with twin-twin transfusion syndrome. Intracranial hemorrhage, detected prenatally, was seen in the larger twin , and periventricular leukomalacia was identified on the first day of life in the smaller twin . Recognition of fetal intracerebral hemorrhage on prenatal sonograms is uncommon; it has been reported only three times (1-3] . The p...

To study the effect of twin boundaries on thermal transmission, thermal conductivities of twinned diamond with different twin thicknesses have been studied by NEMD simulation. Results indicate that twin boundaries show a weak phonon scattering effect on thermal transmission, which is only caused by the additional twin boundaries' thermal resistance. Moreover, according to phonon kinetic theory,...

Background: Comparison of obstetric and neonatal outcomes of twin pregnancies conceived by assisted reproduction technology (ART) with those of spontaneously conceived (SC). Materials and Methods: In this prospective cohort study, all dichorionic twin pregnancies following fresh IVF/ intra-cytoplasmic sperm injection (ICSI) or ICSI cycles (n=320) and (SC) (n=170) in nulliparous women in Royan I...

INTRODUCTION Twin pregnancy is a high-risk pregnancy with different prevalences in different regions of the world which is on the rise due to growing use of assisted reproductive technology. The objective of this study is to determine the frequency of twin pregnancy and the neonatal outcome of these pregnancies. MATERIALS AND METHODS This is a descriptive-analytic study conducted in 2004-2007...

OBJECTIVE Fetal vessel thrombosis has been related to pregnancy complications and adverse neonatal outcomes in singleton pregnancies, but the clinical and pathologic characteristics of fetal thrombosis in twin pregnancy are still ill defined. METHODS To clarify the characteristics of fetal thrombosis in twins, we reviewed the histology slides and medical records of live-born infants of twin p...

The Australian Twin Registry (ATR) is a national volunteer resource of twin pairs and higher-order multiples willing to consider participating in health, medical, and scientific research. The vision of the ATR is 'to realize the full potential of research involving twins to improve the health and well-being of all Australians'. The ATR has been funded continuously by the National Health and Med...

BACKGROUND Our aim was to study attitudes towards twins and single embryo transfer (SET) among IVF/ICSI-twin mothers with 3 to 4-year old children. METHODS A national survey was conducted by questionnaire (n = 1769). The study population consisted of IVF/ICSI-twin mothers (n = 266), and the two control groups of IVF/ICSI-singleton mothers (n = 764) and non-IVF/ICSI-twin mothers (n = 739), all...

Despite the need to provide evidence-based health policy, most developing countries suffer from a lack of resources for sound epidemiologic evidence. Most twin registers have been established in developed countries and there are relatively fewer twin registers in developing countries. Considering the immense potential of twin research, it will be worthwhile to attempt to establish a new twin re...

Twins have a high frequency of adverse perinatal events and have been reported to have an increased risk of seizures. Contrary to popular belief, a recent study reported that twins do not have an increased risk of seizures. We studied the relationship of twinning and epilepsy in India. The frequency of twinning in families of probands with epilepsy was compared with the frequency of twinning am...
