Developmental dysplasia of the hip (DDH) results from the abnormal development of the acetabulum, femoral head and mechanical instability of the hip joint. DDH often presents at birth, and if diagnosed early and treated successfully, children are able to develop a normal hip joint without functional limitation. If left untreated, DDH can lead to pain and osteoarthritis by early adulthood as well as discrepancy in leg length and functional disability. DDH risk factors include breech position in utero, oligohydramnios, female sex, primigravida, family history of DDH and improper swaddling. While there are recommendation for ultrasound screening in breech infants, only a few studies have dealt with the influence of gestational age on the development of DDH. Optimal timing of hip US and identification of patients who need follow-up are important to reduce unnecessary treatment and to avoid overtreatment. We aim to evaluate whether extremely premature infants (<28 weeks gestational age) warrant ultrasound screening for DDH in the absence of other risk factors. Read More

MRS is the best prognostic indicator for hypoxic-ischemic encephalopathy (HIE) but is difficult to obtain early after injury. We investigated whether cerebral blood flow measures of resistive indices (RI) and time average maximum velocities (TAMx) shortly after birth would relate to later degree of neural injury by MRI in hypothermic HIE newborns. We predicted that abnormally high/low blood flow would be associated with poor outcomes. Read More
