Nephrogenic rests (NRs) are considered to be precursor lesions of Wilms tumor, the most common malignant neoplasm of the urinary tract in children. We have previously reported on 2 cases of NRs, incidentally diagnosed at 2 to 3 months of age during an ultrasound mass screening for urinary tract malformations ...

Many ways of detecting hip instability in the newborn infant exist, including a history of risk factors, clinical examination and ultrasound. We investigated our practice of 'at risk' screening using subjective, dynamic and static, ultrasound, followed by radiographic evaluation at 12 months. We found that the average age at presentation ...

Diagnosis of Non-Ketotic Hyperglycinemia by MSMS newborn screening might benefit patients with post-neonatal presentation. We screened 733,527 babies over eight years, and nine babies were subsequently diagnosed with NKHG. Two had newborn glycine levels above our cut-off and presented within 72 h. The remaining patients could not have been diagnosed ...

Distortion product otoacoustic emission (DPOAE) measures of cochlear function, including DPOAE suppression tuning curves and input/output (I/O) functions, are not adultlike in human infants. These findings suggest the cochlear amplifier might be functionally immature in newborns. However, many noncochlear factors influence DPOAEs and must be considered. This study examines whether ...

Primary carnitine deficiency impairs fatty acid oxidation and can result in hypoglycemia, hepatic encephalopathy, cardiomyopathy and sudden death. We diagnosed primary carnitine deficiency in six unrelated women whose unaffected infants were identified with low free carnitine levels (C0) by newborn screening using tandem mass spectrometry. Given the lifetime risk of ...

A common strategy for measuring the real-ear response of the real-ear-to-coupler difference (RECD) in the pediatric population is to insert a probe-tube separately from the eartip. This strategy is at times difficult to implement while attempting to obtain the measurement from a young infant. An RECD probe-tube insertion technique that ...

As more states adopt expanded newborn screening for metabolic disorders, the overall number of false positives increases. False-positive screening results have been associated with increased anxiety and stress in parents of infants who require follow-up testing, even after the infant's good health is confirmed. This article reviews the literature on ...
