Acoustic features of expiratory cry vocalizations were studied in 125 pre-term infants prior to being discharged from a level-3 neonatal intensive care unit. The purpose was to describe various phonatory behaviors in infants in whom significant hearing loss could be ruled out. We also compared these results with normal-hearing full-term infants, and(More)
OBJECTIVE To evaluate a stepped-dose protocol for intralesional injection of cidofovir in children with recurrent respiratory papillomatosis (RRP). DESIGN Prospective, nonrandomized case series. SETTING Tertiary care children's hospital. PARTICIPANTS Eleven children undergoing evaluation for RRP from June 1, 2000, through December 31, 2001. (More)
OBJECTIVE To review our experience with intracapsular tonsillectomy using powered instrumentation in the management of tonsillar hypertrophy causing obstructive sleep-disordered breathing in children. STUDY DESIGN Retrospective case series. METHODS Intracapsular tonsillectomy, a form of partial tonsillectomy performed with an endoscopic microdebrider,(More)
The long-term distributions of trajectories of a flow are described by invariant densities, i.e. fixed points of an associated transfer operator. In addition, global slowly mixing structures , such as almost-invariant sets, which partition phase space into regions that are almost dynamically disconnected, can also be identified by certain eigenfunctions of(More)
Despite advances in radiology--including CT scanning--the three-dimensional (3D) nature of facial fractures must still be inferred by the spatial imagination of the physician. A computer system (Insight Phoenix Data Systems, Inc., Albany, N.Y.) uses CT studies as substrate for 3D reconstructions. We have used the Insight computer for the evaluation and(More)
OBJECTIVE To evaluate the polysomnographic outcomes after supraglottoplasty (SGP) performed for obstructive sleep apnea syndrome (OSAS) associated with occult laryngomalacia. DESIGN Retrospective case series with medical chart review. SETTING Tertiary pediatric medical center. PATIENTS Twenty-two patients aged 2 to 17 years met the inclusion criteria(More)
OBJECTIVE To evaluate the effect driver-side and passenger-side airbags have had on the incidence and severity of maxillofacial trauma in victims of automobile accidents. DESIGN Retrospective analysis of all automobile (passenger cars and light trucks) accidents reported in 1994. SETTING New York State. PATIENTS Of the 595910 individuals involved in(More)
Pediatric obstructive sleep apnea (OSA) is not always resolved or improved with adenotonsillectomy. Persistent or complex cases of pediatric OSA may be due to sites of obstruction in the airway other than the tonsils and adenoids. Identifying these areas in the past has been problematic, and therefore, therapy for OSA in children who have failed(More)
