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.
When a baby is born before the 37th week of pregnancy, it is called a preterm delivery. Some preterm births happen on their own -- a mother goes into labor and her baby comes early. In other cases, problems with the pregnancy prompt doctors to deliver a baby earlier than planned. About three quarters of preterm births are spontaneous and about one quarter occur because of medical complications.
