Aim: The present research was conducted to identify site-specific pain resulting from musculoskeletal disorders (MSDs) among practicing dentists and determine its impact on their quality of life.
Setting and Design: A cross-sectional questionnaire study conducted among practicing dentists of Puducherry Taluk, Puducherry, India.
Method and Materials: A closed-ended, self-administered questionnaire was distributed to 95 practicing dentists to identify site-specific MSP from the study subjects. Data on pain due to MSDs, frequency of pain, its impact on quality of life, relieving factors, patients attended per day, working hours per day, and awareness on ergonomics were also recorded.
Statistical Analyses: The data were analyzed for descriptive statistics, and Chi-square tests was used for proportions.
Results: Almost all respondents experienced pain due to MSDs. Approximately, 11.1% "always" experienced elbow pain; 5.6% "always" experienced pain in neck and back. Approximately, 83% "sometimes" experienced pain in the back. Pain in elbow was significantly associated with gender (P = 0.036), qualification (P = 0.029), and years of practice (P = 0.032). Approximately, 36% reported having an impact on their life.
Conclusion: The magnitude of the problem is slowly shifting from "sometimes" to "always." Although small in proportion, pain due to MSDs has an impact on dental practitioners' quality of life, and elbow pain was reportedly higher in the study setting. Measures need to be implemented before MSD becomes a career limiting occupational hazard.
METHOD: This study utilized a quantitative, nonexperimental, cross-sectional research design. A total of 60 subjects were randomly selected after passing the study's sampling criteria. The Nordic Musculoskeletal Questionnaire (NMQ) was to used to determine common MSDs affecting the various regions in the body. The Demographic Pofile Sheet was provided to gather a subject's demographic characteristics.
RESULTS: Filipino migrant workers mostly complain of pain in the low back area (60%) and shoulder pain (60%), followed by pain in the upper back (48.3%) and neck pain (45%) in the last 12 months. Household workers accounting for 73.3% of the subjects commonly complain of pain in the hips/thighs (78.9%), while workers in the service industry commonly complain of knee pain (39.1%).
CONCLUSIONS: Results imply that Filipino migrant workers have a higher prevalence of shoulder and lower back pain in the last 12 months. Household workers are more susceptible to hip/thigh pain. Interventions focusing on ergonomics policy implementation, education on posture and lifting techniques and physical function is recommended. Further studies should consider the psychological and psychosocial aspects of migrant employment, which are known risk factors for MSDs.
OBJECTIVE: To investigate the association between postoperative upper instrumented vertebrae (UIV) tilt angle with postoperative medial shoulder and neck imbalance.
SUMMARY OF BACKGROUND DATA: Studies had found that current recommendations for UIV selection were not predictive of good postoperative shoulder balance.
METHODS: A total of 98 patients with adolescent idiopathic scoliosis with Lenke 1/2 curves who underwent posterior spinal fusion between 2013 and 2014 with minimum follow-up of 2 years were recruited. Radiological parameters: UIV tilt angle, T1 tilt, cervical axis, and clavicle angle were measured preoperatively, postoperatively, and at final follow-up.
RESULTS: Mean age was 16.2 ± 6.2 years. Mean follow-up was 37.9 ± 6.5 months. There were 73.5% Lenke 1 and 26.5% Lenke 2 curves. Significant factors affecting postoperative T1 Tilt were postoperative UIV tilt angle, preoperative T1 tilt, and preoperative UIV tilt angle. Postoperative UIV tilt angle and preoperative cervical axis were significant factors affecting cervical axis at final follow-up. UIV level was not significant independent factor that affected postoperative T1 tilt and cervical axis. There was strong correlation between postoperative UIV tilt angle and T1 tilt for the whole cohort (P
Methodology: Thirty rats were treated to receive 0.5 mL phosphate-buffered saline (group A, control), 0.5 mL corn oil (group B), 0.2% CPZ (group C), for 6 weeks, 0.2% CPZ for 3 weeks and then 200 mg/kg of Kv for 3 weeks (group D), or 200 mg/kg of Kv for 3 weeks followed by 0.2% CPZ for 3 weeks (group E). Rats were assessed for exploratory functions and anxiety-like behaviour before being euthanised and perfused transcardially with 4% paraformaldehyde. Prefrontal and hippocampal thin sections were stained in hematoxylin and eosin and cresyl fast violet stains.
Results: CPZ-induced demyelination resulted in behavioural impairment as seen by reduced exploratory activities, rearing behaviour, stretch attend posture, center square entry, and anxiogenic characteristics. Degenerative changes including pyknosis, karyorrhexis, neuronal hypertrophy, and reduced Nissl integrity were also seen. Animals treated with Kv showed significant improvement in behavioural outcomes and a comparatively normal cytoarchitectural profile.
Conclusion: Kv provides protective roles against CPZ-induced neurotoxicity through prevention of ribosomal protein degradation.
