Comparative Study40-Hz multiple auditory steady-state responses to narrow-band chirps in sedated and anaesthetized infants.
The general consensus to date has been that a stimulus repetition rate of 40Hz is not appropriate for the recording of auditory steady-state responses (ASSR) in sedated or anaesthetized infants. The aim of this study was to investigate whether reliable 40-Hz ASSR thresholds can be obtained in sedated infants using narrow-band chirp stimuli in the clinical routine. ⋯ In contrast to the general assumption that 40-Hz ASSR are not appropriate for threshold estimation in infants our results demonstrate that multiple ASSR with a stimulus repetition rate of 40Hz can be recorded in sedated and anaesthetized infants using narrow-band chirps. Threshold estimates obtained with 40-Hz ASSR are, on average, slightly higher than those obtained with chirp evoked ABR but allow for a frequency specific characterisation of the hearing ability.

Otogenic lateral sinus thrombosis: case series and controversies.
The aim of this study is to (1) report the clinical presentation, treatment, and sequelae in a series of pediatric patients with otogenic lateral sinus thrombosis and (2) to review the most controversial aspects of management of this rare intracranial complication of otitis media. ⋯ Otogenic lateral sinus thrombosis is a rare intracranial complication of otitis media with significantly reduced morbidity and mortality in the modern era of antibiotic treatment, surgical intervention, and anticoagulation therapy. Due to the rarity of this condition today, the recommended extent of surgical intervention and need for routine anticoagulation are unclear, and requires further data to determine definitively.

Auditing of operating room times: a quality improvement project.
A quality improvement project to evaluate operating room efficiency and utilization and to identify areas for improvement. ⋯ The operating room represents one of a hospital's most costly resources. Ensuring that this resource is designed, staffed and utilized efficiently is of major importance to both the quality of patient care and financial productivity. Surgeons are key components of operating room efficiency, utilization and other measurements of institutional performance. How surgeons schedule and perform cases directly impacts, and is impacted by, these measurements of performance. For fields dominated by high volume, short duration procedures such as pediatric otolaryngology, T4 may be the most important variable in determining OR efficiency. By utilizing modern electronic medical records, surgeons can easily track OR time points thereby determining the potential causes of and solutions for OR inefficiency.
