Background: Low back pain (LBP) is a common musculoskeletal problem in recent days, and 85% of LBP is NSLBP. Studies have shown that psoas syndrome can be the cause of pain in lumbosacral region in a clinical scenario. Aims and Objectives: To find out the immediate effect of contract-relax antagonist-contract (CRAC) method on iliopsoas muscle and hamstring muscle stretching on chronic NSLBP. Materials and Methods: Totally 30 subjects from both genders were selected based on inclusion criteria were aged from 20 to 30 years, chronic NSLBP of more than 3 months, iliopsoas muscle tightness at least one side ("positive" from modified Thomas test). Pain intensity at least 3/10 on a 10-cm visual analog scale (VAS). Hamstring tightness with a minimum of −6 cm (male), −10 cm (females) done by sit and reach test. CRAC technique and hamstring stretching were administered. Results: Pre-and post-test values of all the outcomes measure are 0.000, there is a significant result exist between the VAS scale, hamstring and iliopsoas flexibility, before and after the interventions (P < 0.05). Conclusion: CRAC stretching technique combined with hamstring stretching can reduce back pain.

Neo adjuvant chemotherapy has been studied in oral cavity with the aim of improving locoregional control and overall survival rates as an organ preservation tool in the resettable cancers. It is usually given post operative to improve the quality of life and to increase the survival rates. This study was conducted by reviewing the records of patients visiting the Oral Oncology department in Saveetha Dental College and hospitals, between 1 st June 2019 -1 st April 2020. Among 57 carcinoma patients (maxillary, mandibular, buccal carcinoma) 16 (28%) patients were treated with the chemotherapy post operatively. There was male predominance with 9 males (57%) and 7 females (43%) in this study. The mean age of the patient's undergoing chemotherapy was 40-50 years, ranging from 20 to 60 years of age. Among various sites of carcinoma patients subjected to chemotherapy, maxillary carcinoma accounted to 8 patients (50%) mandibular carcinoma-5 patients (31.25%), buccal mucosa carcinoma-3 patients (18.75%) Chi-square test was done on association between gender and number of patients with carcinoma in different sites and found not statistically significant [chi square value-0.2320, p value-0.314 (p>0.05)]. Chi-square test was done to find the association between age and type of carcinoma and was found to be statistically not significant [chi square value-0.529, p value-0.612(p>0.05)]. From this study we can conclude that chemotherapy treatment was commonly undergone by men and patients in the 4th decade of life. Maxillary carcinoma patients underwent chemotherapy more commonly as compared to mandibular carcinoma patients or buccal carcinoma patients. Association between age and incidence of chemotherapy treatment, gender and incidence of chemotherapy treatment was found statistically not significant.
