Safety and Efficacy of the Mandibular Advancement Device 'Bioguard' for the Treatment of Obstructive Sleep Apnea: A Prospective, Multi-Center, Single Group, and Non-Inferiority Trial / 수면정신생리

OBJECTIVES: The purpose of this study was to estimate the safety and efficacy of a mandibular advancement device (MAD), 'Bioguard,' for the treatment of obstructive sleep apnea (OSA). METHODS: In this 5-week prospective, multi-center, single group, and non-inferiority trial, patients who chose 'Bioguard' as their treatment option were evaluated using both questionnaires (Pittsburgh Sleep Quality Index (PSQI), Epworth sleepiness scale (ESS)) and polysomonography (PSG) (apnea hypopnea index (AHI), oxygen saturation). All patient data, including clinical records, PSG studies (both pre- and post-treatment), and adverse events (AEs), were reviewed and analyzed. RESULTS: Results were obtained for 59 of 62 patients (95.16%). No significant difference in success rate was found between the MAD treatment and surgical treatment (95% CI). AHI, PSQI, ESS and oxygen saturation demonstrated significant improvement (p < 0.001) after MAD treatment, and 39 of 62 patients (62.9%) reported 85 AEs. 79 of the 85 AEs (91.8%) were mild cases, and there were no severe AEs related to the MAD treatment. CONCLUSION: The MAD 'Bioguard' should be considered as an alternative treatment option for OSA patients.

A Study of Reliability and Validity on the Korean Version of Clinician Administered PTSD Scale for Children and Adolescents / 신경정신의학

OBJECTIVES: This present study was conducted to explore the reliability and the validity of Clinician Administered PTSD Scale for Children and Adolescents Korean version (CAPS-CA). METHODS: The Subjects were children and adolescents (8-13yrs) from different places: a certain elementary school, three orphanages, a general hospital, and two neuropsychiatric local clinics. Only subjects who experienced a catastrophic traumatic event were tested by CAPS-CA, CDI, RCMAS, and TSC. RESULTS: The range of correlations between item-criterion were .67-.84. The coefficients of internal consistency were .87. and test-retest reliability was .90, were all the coefficients in the proper range. Inter-correlations of CAPS-CA, CDI, RCMAS, and TSC scale showed significant correlation. TSC showed the highest correlation coefficient. CAPS-CA can be a useful clinician- administered diagnostic instrument for children and adolescents PTSD symptoms. CONCLUSION: The reliability and the validity of CAPS-CA were confirmed. CAPS-CA could be applied for diagnostic purposes of PTSD in children and adolescents.
