Abstract
- PURPOSE
In Korea, neonatal clinical features and feeding pattern are not reported systematically. So we report the neonatal presentation of Prader-Willi syndrome.
METHODS
This is a retrospective study of 14 neonate with Prader-Willi syndrome whose diagnosed in neonatal intensive care unit, Samsung Medical Center between January 1st 1997 and December 30th 2011.
RESULTS
The birth characteristics of patients, maternal age was 31.5+/-4.5 years and 5 (35.7%) were primiparous. Oligohydramnios were reported in 2 cases (14.2%), polyhydramnios were reported in 4 cases (28.5%). 5 pregnancies (35.7%) had complained that decreased fetal movements. Mean gestational age were 38.1+/-2.2 weeks and 12 patients (85%) were term infants, one patient (7.1%) was post term infant, the other patient was preterm infants (7.1%). The average weight at birth were 2509.0+/-442.5 grams. All 14 patients (100%) had hypotonia and a weak cry at birth. 9 patients (64.5%) had the characteristic facial dysplasia. In all, nine male patients (100%) had cryptorchidism. All patients had weak sucking power, so they started to eat via nasogastric tube at birth. The mean duration of use nasogastric tube were 3.2+/-2.0 months. The median age of diagnosis were 1.5 months. 7 cases (50%) were diagnosed within one month of life. Median time of starting GH treatment was 2.0 years. The mean interval of from diagnosis to treatment of growth hormone were 2.2+/-2.0 years.
CONCLUSION
Early diagnosis of Prader-Willi syndrome is a very important to improve long-term prognosis.
