Raynaud's is a fairly rare disorder of the blood vessels supplying the skin. During a Raynaud's attack, the blood vessels narrow, limiting blood circulation to affected areas. It makes parts of your body (usually fingers, toes, nose and ears) feel numb and cool in cold temperatures or under stress.
PPROM is associated with 30-40% of preterm deliveries and is the leading identifiable cause of preterm delivery. PPROM complicates 3% of all pregnancies and occurs in approximately 150,000 pregnancies yearly in the United States.
Premature infants, known as preemies, come into the world earlier than full-term babies. Prematurity is when a pregnancy lasts less than 37 weeks; full-term infants are born 37 to 42 weeks after the mother's last menstrual period (LMP). Thanks to recent medical advances, most premature babies survive.
