METHODOLOGY: This is a descriptive cross-sectional study at the Sleep Clinic, Department of Otorhinolaryngology-Head and Neck Surgery. Flexible nasopharyngolaryngoscopy was performed in seated erect and supine position. Retropalatal and retroglossal regions were continuously recorded during quiet breathing and Mueller's maneuver in both positions. Captured images were measured using Scion Image software and narrowing rate was calculated. Level of each site was classified based on Fujita classification and severity of obstruction using Sher scoring system for Mueller's maneuver.
RESULTS: A total of 59 patients participated in this study. Twenty-nine (49.2%) participants had type 1 (retropalatal) obstruction, 23 (38.9%) had type 2 (retropalatal and retroglossal), and seven (11.9%) in type 3 (retroglossal) obstruction. Fifty (84.7%) of the patients have severe obstruction at the retropalatal region in supine position (SRP) followed by 35 (59.3%) at retropalatal region in erect position (ERP), 27 (45.8%) at retroglossal region in supine position (SRG) and eight (13.5%) at retroglossal region in erect position (ERG). The average oxygen saturation showed significant association in ERP (P = 0.012) and SRP (P < 0.001), but not significant in ERG and SRG.
CONCLUSIONS: Videoendoscopy utilizing flexible nasopharyngolaryngoscopy and Scion Image software is reliable, minimally invasive, and useful as an office procedure in evaluating the multilevel obstruction of upper airway in OSA patients. The retropalatal region has more severe obstruction compared with retroglossal region either in erect or supine position.
Methods: A qualitative phenomenological study was conducted on a group of Universiti Sains Malaysia medical students who had finished the Community and Family Case Study (CFCS) program. Data were gathered through focused group discussions and student reflective journals. Participants were sampled using the maximal variation technique of purposive sampling. Three steps of thematic analysis using the Atlasti software were employed to identify categories, subthemes, and themes.
Results: Personal, role, social, and research identities were generated that contribute to the PID of medical students through the CFCS program. The results indicate that the CFCS program nurtured personal identity through the development of professional skills, soft skills, and personal values. Pertaining to role identity, this is related to patient care in terms of primary care and interprofessional awareness. Pertaining to social identity, the obvious feature was community awareness related to culture, society, and politics. A positive outcome of the CFCS program was found to be its fostering of research skills, which is related to the use of epidemiology and research methods.
Conclusion: The findings indicate that the CFCS program promotes PID among medical students. The current data highlight and provide insights into the importance of integrating CBE into medical curricula to prepare future doctors for their entry into the profession.
