introduction: one of the most common complaints in pregnancy is sleep disturbances which can cause depression. depression, too, is one of the most common complaints in pregnancy that can affect mother and fetus and even mother and neonate in postpartum period. therefore this research was accomplished by the objective assessment of relationship between sleep pattern and depression in the third t...
INTRODUCTION Weight of placenta has long been associated with fetal growth and perinatal well-being. Low placental weight (standardized for sex gestational age) is more common among stillbirths whereas high neonatal death, serious morbidity, low 5-min Apgar score, respiratory morbidity. believed to reflect an inadequate surface area nutrient gas exchange, leading compromise. However, it also pro...
Four behavioural states are recognised in the human fetus and are comparable to those of the neonate: 1F (quiet sleep), 2F (active state), 3F (quiet awake), and 4F (active awake). State 5, or crying, is not considered to have a fetal correlate. In a study assessing the effects of exposure to tobacco and cocaine during pregnancy on fetal response and habituation to vibroacoustic stimulation, wha...
Ann Saudi Med 30(2) March-April 2010 www.saudiannals.net 171 A two-hour-old female neonate, a product of nonconsanguineous marriage with unremarkable family history, was brought with well-defined bilaterally symmetrical and superficial erosions on the knees, trunk and lower limbs with sparing of scalp and mucosa (Figure 1). Biopsy revealed an absence of epidermis and superficial dermis. Antenat...
Mercury vapor is known penetrate the placental barrier more easily than inorganic mercury. A relative amount of mercury accumulates in the fetus after exposure of pregnant animals to mercury vapor. Mercury concentration in fetal organs is much lower than that in maternal organs except the liver, and fetal liver shows significantly higher mercury concentrations than maternal liver. In fetal live...
The Panel has been asked to reconsider the possible age-dependent toxicokinetics of BPA in animals and humans and their implication for hazard and risk assessment of BPA in food. The Panel concluded that the exposure of a human fetus to free BPA would be negligible due to the maternal capacity for conjugation whereas the fetal rat would be exposed to free BPA from the maternal circulation. Taki...
Humoral immunity is a critical component of the immune system that is established during fetal life and expands upon exposure to pathogens. The extensive humoral immune response repertoire is generated in large part via immunoglobulin (Ig) heavy chain variable region diversity. The horse is a useful model to study the development of humoral diversity because the placenta does not transfer mater...
Double aortic arch (DAA) is a form of vascular ring found in approximately 1 in 2000–4000 pregnancies on fetal echocardiography. In some cases of DAA, respiratory compromise occurs during infancy due to compression of the trachea, which is completely encircled by the right aortic arch (RAA) and left aortic arch (LAA). RAA and left arterial duct were initially seen on screening fetal echocardiog...
Primary sclerosing cholangitis is a progressive disease, and coincidentally in pregnancy it is rare. It is characterized by progressive inflammation and destruction of bile ducts finally resulting in liver failure. A rare case of primary sclerosing cholangitis in pregnancy is presented. The course of the pregnancy was marked by threatened preterm delivery and exacerbation of cholestasis. She wa...
Vein of Galen malformation (VOGM) is a rare congenital vascular malformation caused by the maldevelopment of its embryonic precursor, the median prosencephalic vein of Markowski. VOGM results in neonatal morbidity and mortality, and premature delivery does not improve the outcome. We report a term female neonate in whom a vein of Galen malformation was diagnosed prenatally at 37 wk of gestation...
