Q

A 38 y/o primigravida has premature rupture of membranes at 36 weeks gestation, necessitating delivery. At birth, the infant is noted to have a two vessel umbilical cord, a cleft lip, a heart murmur and spina bifida. Which of the following factors is most likely to increase the risk of hyaline membrane disease in the infant?
a. Chorioamnionitis
b. DM, type 1
c. Maternal corticosteroid therapy
d. Oligohydramnios

A

b. DM, type 1

The hyperinsulinism in the fetus of a diabetic mother suppresses pulmonary surfactant production. Corticosteroids stimulate surfactant production in type II pneumocytes. Infection may increase the risk of premature birth, but it does not significantly affect surfactant production. The risk for major malformations, called diabetic embryopathy, is 6% to 10% in infants born to mothers with diabetes mellitus; but there is no set pattern to the anomalies, and similar embryopathies are not seen in gestational diabetes. So the cause for anomalies here is unknown. Macrosomia is the result of growth-promoting effects of insulin in the fetus. Oligohydramnios leads to constriction in utero that culminates in pulmonary hypoplasia, not decreased surfactant. Maternal hypertension may reduce placental function and increase growth retardation, but it typically does not have a significant effect on the production of surfactant.

Q

Physical examination of a newborn revealed microcephaly, frontal bossing, long and narrow forehead, maxillary and mandibular hypoplasia, narrow palpebral fissures, thin elongated philtrum. Ocular problems include microphthalmia, corneal clouding, coloboma and proptosis, A systolic murmur is heard auscultation and echocardiography revealed ventricular septal defect. Which of the following conditions is most likely to produce these findings?
a. Congenital rubella
b. Fetal alcohol syndrome
c. Maternal diabetes mellitus
d. Trisomy 21

A

b. Fetal alcohol syndrome

Alcohol is one of the most common environmental teratogens affecting fetuses, although the effects can be subtle. There is no threshold amount of alcohol consumption by the mother to produce fetal alcohol syndrome; no amount is safe. Children with fetal alcohol syndrome tend to be developmentally impaired throughout childhood, but the physical anomalies tend to become less apparent as the child matures. Vertebral abnormalities, including scoliosis, can be present. The liver can have fatty metamorphosis with hepatomegaly and elevated serum transaminases. The major effects of congenital rubella occur during organogenesis in the first trimester and result in more pronounced defects, including congenital heart disease. Maternal diabetes often results in a larger infant, and malformations may be present. Placenta previa, a low-lying placenta at or near the cervical os, can cause significant hemorrhage at the time of delivery or uteroplacental insufficiency with growth retardation before delivery. Placental causes of intrauterine growth retardation result in asymmetric growth retardation with sparing of the brain. The findings of trisomy 21 are subtle at birth, but typically include brachycephaly, not microcephaly.
