Sleep Disorders among Dental Students: An Original Research.

Introduction: With the increased stress among the students, their sleep patterns have been derailed from the routine. Hence, in our study, we aimed to appraise among the dental students the occurrence of sleep disorders. Materials and Methods: We conducted a questionnaire-based survey study among 1115 dental students of 1-4 years. The survey was based on SLEEP-50 that had 50 questions that were given scores from 1 to 4 based on the response. The scores were analyzed for the statistical connotation, keeping P < 0.05 as significant. Results: We observed that 352 students suffered from sleep disorders. The sex ratio of male:female was 25:75. No significant age variation was seen. For the various disorders, insomnia (25%), nightmares (13%), and sleepwalk (8%), circadian rhythm disorders (34%), obstructive sleep apnea (26%), and narcolepsy (30%) were noted with significant variation. The habit of alcohol was seen in 17% of students. Conclusions: The sleep disorders were prevalent among the dental students due to the great amount of stress caused in the study. They should be educated about the stress management methods and importance of sleep.

Variation in Tendinous Intersections of Rectus Abdominis Muscle in North Indian Population with Clinical Implications.

AIM OF THE STUDY: Incisions through the abdominal wall are based on anatomical principles and Rectus abdominis muscle provides an excellent myocutaneous flap. The present work was proposed to identify variations in numbers and location of tendinous intersections of the Rectus Abdominis muscle in the cadavers as a guide to the surgical procedures. MATERIALS AND METHODS: The study was conducted on 54 cadavers of North Indian origin allotted to undergraduate medical student for Anatomy dissection classes. Manual dissection was done to identify tendinous intersections of the Rectus Abdominis muscle with reference to number and location. RESULTS: In the present study one cadaver had five tendinous intersections (1.85%), one cadaver had four tendinous intersections (1.85%) and 52 cadavers had three tendinous intersections (96.29%). CONCLUSION: The present study is an effort to provide data about the anatomical variation in numbers and location of tendinous intersections of the Rectus Abdomini muscles. Rectus abdominis muscle provides an excellent myocutaneous flap because the muscle belly is separated from surrounding tissue within the rectus sheath. This study is representative of a small study of the human population and only serves to illustrate the variations in the anatomy of the tendinous intersections. More extensive studies are required to establish a definitive pattern among local populations to serve as a guide for surgical procedures.
