Comparative StudyEffective comparison of two auto-CPAP devices for treatment of obstructive sleep apnea based on polysomnographic evaluation.
Automatic continuous positive airway pressure (auto-CPAP) machines differ mainly in algorithms used for respiratory event detection and pressure control. The auto-CPAP machines operated by novel algorithms are expected to have better performance than the earlier ones in the treatment of obstructive sleep apnea syndrome (OSAS). ⋯ These findings suggest that the f-APAP works better than the v-APAP in abolishing breathing abnormities in the treatment of OSAS; however, the f-APAP device might still have some potential limitations in the clinical application.

Case ReportsTreatment of scattered glass foreign bodies in both the superficial and deep neck: a case report.
There have not been any reports about scattered glass foreign bodies in the neck, while injuries of the head and neck region as a result of traffic accidents have been frequently reported. We report the case of a 17-year-old male injured in a traffic accident, with scattered glass foreign bodies in both the superficial and deep neck. A CT scan indicated the existence of numerous glass foreign bodies in the various layers of the neck. ⋯ The wounded skin was keloidal and expected to lead to remarkable facial edema of the left side. The foreign bodies and cervical keloidal lesions with small pieces of glass were carefully removed, and then reconstruction was conducted in stages using tissue expanders. The facial edema was reversed and the aesthetic reconstruction satisfied the patient.

Case ReportsA case with tracheo-innominate artery fistula. Successful management of endovascular embolization of innominate artery.
Tracheo-innominate artery fistula (TIF) is known as a fatal complication after tracheostomy. We report a 9-year-old girl with early hypoxic encephalopathy who had a tracheo-innominate artery fistula with exsanguinating hemorrhage from her tracheostoma 10 months after tracheostomy. ⋯ The patient has remained well 1 year after the procedure. We reviewed the aetiology, diagnosis and management of the tracheo-innominate fistula, and findings suggest that endovascular embolization of the innominate artery may be an appropriate treatment for patients with tracheo-innominate artery fistula.

Validity and limitation of manual rotational test to detect impaired visual-vestibular interaction due to cerebellar disorders.
The aim of this study was to investigate validity and limitation of the novel infrared system to record and analyze horizontal visual-vestibular interaction using whole-body rotation rapidly and conveniently in the routine vestibular clinic. We examined 11 patients with cerebellar dysequilibrium and 25 patients with peripheral dysequilibrium for vestibulo-ocular reflex in darkness (DVOR), visually-enhanced vestibulo-ocular reflex (VEVOR), and fixation suppression of vestibulo-ocular reflex (FSVOR), and compared the results with those of examination for head-fixed smooth pursuit and fixation suppression during caloric stimulation. The manual rotation stimuli were 0.5-0.75 Hz in frequency and 60-90 degrees /s in maximal angular velocity. ⋯ On the other hand, there was no significant difference among the two disease groups and the normal control group in gain of visually-enhanced vestibulo-ocular reflex. In about a half of patients with cerebellar dysequilibrium, measured smooth pursuit gain was lower than estimated smooth pursuit gain calculated based on a simple superposition theory of vestibulo-ocular reflex and smooth pursuit. Testing fixation suppression using the present system is an unusually convenient tool for detection of cerebellar dysequilibrium.

Effects of aminoglycoside administration on cochlear elements in human temporal bones.
Although there have been numerous reports on the relationship between the period of aminoglycoside administration and cochlear damage in animals, to date there have been no such studies in humans. The purpose of this study is to observe the early and late cochlear effects of aminoglycoside administration on hair cells, spiral ganglion cells, stria vascularis, and spiral ligament. ⋯ This study demonstrates that in a short period (within 2 weeks) after aminoglycoside administration, a decrease in hair cells and in the area of the stria vascularis occurred.
