The placenta is a vital organ necessary for healthy fetal development. Placental insufficiency creates an in utero environment where the fetus is at risk of insufficient oxygen or nutrient exchange. This is primarily caused by impairment of either maternal or fetal circulation or vascular thrombosis such as placental infarction. As a result of placental dysfunction, affected fetuses may be growth restricted, neurologically impaired, and at risk of increased morbidity and mortality. In a cohort of 4 pregnant Rhesus macaques, we describe antenatal detection of naturally occurring intrauterine growth restriction (IUGR) and aberrant fetal neurodevelopment in 1 animal...

INTRODUCTION: The combination of bilateral microphthalmos, cystic coloboma and eyelid agenesis is rare. The definite diagnosis of this malformation is established by fundoscopic examination and confirmed by imaging modalities such as ultrasonography (US) and magnetic resonance imaging (MRI). This disorder may be associated with specific chromosomal abnormalities. CASE REPORT: A 1-week-old male newborn was referred for bilateral eyelid agenesis. He was born at term by caesarean for foetal distress, after an uneventful gestation...

Congenital Zika virus infection has stimulated great international concern. A prospective case series of 87 infants with laboratory-confirmed congenital Zika syndrome (CZS) at the epicenter of the Brazilian Zika epidemic in Pernambuco state is presented. Mothers were interviewed for symptoms of possible Zika virus (ZIKV) infection during pregnancy and fetal ultrasounds were obtained. Infant cerebrospinal fluid (CSF) samples were tested for ZIKV specific antibodies and sera were screened for other congenital infections...

There is growing evidence that advanced maternal age is a risk factor for neurological and neuropsychiatric disorders in offspring. However, it remains unclear whether the altered brain programming induced by advanced maternal age is mediated by pre- or postnatal factors. Here, a mouse model was used to investigate whether pregnancy at advanced age may provoke behavioral and brain gene expression changes in offspring. Swiss Albino mice conceived by 3-month-old males and either 15-18-month-old (n = 11) or 3-month-old control females (n = 5), were delivered by cesarean section, fostered after birth by 3-month-old dams and subjected to a battery of behavioral tests...

The premise that ultrasound technologies provide reassurance for pregnant women is well-rehearsed. However, there has been little research about how this reassurance is articulated and understood by both expectant mothers and health care professionals. In this article, we draw on two qualitative UK studies to explore the salience of ultrasound reassurance to women's pregnancy experiences whilst highlighting issues around articulation and silence. Specifically, we capture how expectant parents express a general need for reassurance and how visualisation and the conduct of professionals have a crucial role to play in accomplishing a sense of reassurance...

Idiopathic granulomatous mastitis (IGM) is a rare chronic inflammatory disease of the breast, and its etiology remains not fully elucidated. IGM is observed more often in patients with autoimmune disease. Hyperprolactinemia is observed during pregnancy, lactation, and a history of oral contraceptive use. A 39-year-old patient with no history of oral contraceptive use presented with complaints such as redness, pain, and swelling in her left breast. Ultrasound and magnetic resonance imaging (MRI) revealed a suspicious inflamed mass lesion...

BACKGROUND: The antenatal diagnosis of a combined esophageal atresia without tracheoesophageal fistula and duodenal atresia with or without gastric perforation is a rare occurrence. These diagnoses are difficult and can be suspected on ultrasound by nonspecific findings including a small stomach and polyhydramnios. Fetal magnetic resonance imaging adds significant anatomical detail and can aid in the diagnosis of these complicated cases. Upon an extensive literature review, there are no reports documenting these combined findings in a twin pregnancy...
