Bright light has recently been shown to have phase-shifting effects on human circadian rhythms. In this study we applied this effect to 20 patients with delayed sleep phase syndrome (DSPS) who were unable to fall asleep at conventional clock times and had a problem staying alert in the morning. In a controlled treatment study, we found that 2 h of bright light exposure in the morning together w...

Forty six prepubertal boys who had constitutional growth delay were treated with oxandrolone. Mean age at the onset of treatment was 11.9 years (range 9.0-14.0) and bone age delay was 1.9 'years'. The dose of oxandrolone used was a mean of 0.05 mg/kg (range 0.03-0.18) for a mean of 0.9 years (range 0.2-3.6). Height velocity increased from a mean (SD) before treatment of 4.0 (1.0) to 7.5 (1.2) c...

The present investigation seeks to assess to what extent some Dutch phonemes can serve as cues in auditory voice identification of telephone speech. Four Dutch consonants, /x/, /r/, /s/ and /p/, occurring in three different contexts in 24 monosyllabic words, were selected on the basis of their different auditory interspeaker variability. The words were pronounced by 16 speakers in two guises, o...

Unclamped umbilical cord may cause inconvenience in preterm neonates because they commonly need some levels of emergent services. Some studies revealed delayed cord clamping (DCC) of preterm neonates results in be...

Background and Aim: This study aimed to present the results of early and delayed operation on patients with ruptured brain aneurysms. In addition to comparing the results and rates of morbidity and mortality in the surgical procedure and identifying the effective factors, this study aimed to provide methods to improve the treatment of brain aneurysm. Methods and Materials/Patients: This was a ...
