A Meckel's diverticulum may result in a number of complications including hemorrhage, obstruction, and inflammation. We report a case of a gangrenous Meckel's diverticulum secondary to axial torsion, which has been reported only four times in adults and once in children in the past 28 years.
The etiology of craniosynostosis remains unknown. The beta group of transforming growth factors (TGF-beta) and insulin-like growth factors (IGF-I and IGF-II) are known to induce new bone formation and, when added exogenously, cause accelerated closure of calvarial defects. The possible roles of these bone growth factors in premature cranial suture fusion in(More)
The biology underlying normal and premature cranial suture fusion remains unknown. The purpose of this study was to investigate the role of the dura mater in cranial suture fusion. In the Sprague Dawley rat model, the posterior frontal cranial suture fuses between 10 and 20 days of postnatal life. The effect of separating the posterior frontal cranial(More)
The influence of dura mater on adjacent cranial sutures is significant. By better understanding the mechanisms of normal suture fusion and the role of the dura mater, it may be possible to delineate the events responsible for the premature suture fusion seen in craniosynostosis. In the Sprague-Dawley rat, the posterior frontal suture normally fuses between(More)
Distraction osteogenesis has become an accepted method of treatment for patients requiring reconstruction of hypoplastic mandibles. We present a quantitative analysis of volumetric changes after distraction osteogenesis in a series of 10 patients. Group I (n = 5 patients, 3 unilateral craniofacial microsomia, 1 Goldenhaar syndrome, and 1 bilateral(More)
OBJECTIVES/HYPOTHESIS To compare speech perception performance with right versus left cochlear implants (CIs) in children with bilateral CIs implanted simultaneously. STUDY DESIGN Prospective case series of patients undergoing simultaneous bilateral cochlear implantation. METHODS Speech perception performance was tested in 10, right-handed children who(More)
AIM   The aim of this study was to characterize the auditory brainstem responses (ABRs) of young children with suspected autism spectrum disorders (ASDs) and compare them with the ABRs of children with language delay and with clinical norms. METHOD   The ABRs of 26 children with suspected ASDs (21 males, five females; mean age 32.5 mo) and an age- and(More)
Following a recent report by Moore (Auditory learning: implications for speech perception. Proceedings of ISCA Workshop on Plasticity in Speech Perception [PSP2005], London, UK, 2005), showing in a frequency discrimination task that perceptual learning can occur in the absence of perceived stimuli, we further investigated the effects of training with(More)
While it is well documented that significant improvements in a frequency discrimination task occur following training of normal-hearing adult subjects, less is known about the symmetry between the ears. The objectives of the present study were (1) to compare the first obtained DLF thresholds between left and right ears, (2) to determine whether(More)
Premature cranial suture fusion, or craniosynostosis, can result in gross aberrations of craniofacial growth. The biology underlying cranial suture fusion remains poorly understood. Previous studies of the Sprague-Dawley rat posterior frontal suture, which fuses at between 12 and 20 days, have suggested that the regional dura mater beneath the cranial(More)
