Sacrum magnetic resonance imaging for low back and tail bone pain: A quality initiative to evaluate and improve imaging utility

As quality and cost effectiveness become essential in clinical practice, an evidence-based evaluation of the utility of imaging orders becomes an important consideration for radiology’s value in patient care. We report an institutional quality improvement project including a retrospective review of utility of sacrum magnetic resonance (MR) imaging for low back pain at our institution over a four-year period and follow-up results after physician education intervention. Sacral MR imaging for low back pain and tailbone pain were only positive for major findings in 2/98 (2%) cases, and no major changes in patient management related to imaging findings occurred over this period, resulting in almost $500000 cost without significant patient benefit. We distributed these results to the Family Medicine department and clinics that frequently placed this order. An approximately 83% drop in ordering rate occurred over the ensuing 3 mo follow-up period. Sacrum MR imaging for low back pain and tail bone pain has not been a cost-effective diagnostic tool at our institution. Physician education was a useful tool in reducing overutilization of this study, with a remarkable drop in such studies after sharing these findings with primary care physicians at the institution. In conclusion, sacrum MR imaging rarely elucidates the cause of low back/tail pain diagnosed in a primary care setting and is even less likely to result in major changes in management. The practice can be adopted in other institutions for the benefit of their patients and improve cost efficiency.     

Anxiety as a consequence of modern dietary pattern in adults in Tehran—Iran

Food intake patterns in relation to mental health have already been revealed. To investigate the relationship between processed food consumption behavior and anxiety disorder, a cross sectional study was conducted. Overall, 1782 young adults aged 18–35 years were randomly selected using cluster sampling method from 22 districts of Tehran—Iran in 2011. Diet assessment was done using a 24 hour recall questionnaire in two times with a week interval. Anxiety level was determined using the validated Speilburger test (Persian version). A proportional odds regression model was used to assess the effect of processed food consumption on anxiety variables. A significant statistical difference was found between men and women in terms of processed food consumption (p < 0.001). Adjusting for age, total calorie intake, gender, body mass index, socioeconomic status, and history of sedative drug consumption as well as mental health disorders, the proportional odds regression model showed a significant relationship between increased consumption of processed foods and anxiety (OR = 4.73, 95% CI: 2.89–12.54 for state and OR = 4.91, 95% CI: 2.88–13.99 for trait). Identification, modification and adjusting incorrect food patterns in the community could be considered as valuable steps to turn down nutritional-based health difficulties.     

Spontaneous perforation of common bile duct in a pediatric patient: application of hepatobiliary scintigraphy

ABSTRACT: We report a case of spontaneous biliary perforation in a 21-month old female pediatric patient with the presenting symptoms of abdominal distension, jaundice, and umbilical hernia. Hepatobiliary scintigraphy showed tracer accumulation in the peritoneal cavity. Preliminary diagnosis of spontaneous biliary perforation was confirmed during surgery. After surgical repair of the biliary leakage, the patient recovered fully. This case shows the importance of hepatobiliary scintigraphy in patients suspicious for this condition.     

The association between bladder-emptying methods and health-related quality of life among Iranian individuals with spinal cord injury

Objectives: In this study, we compared the health-related quality of life (HRQoL) among patients with spinal cord injury (SCI) using different bladder emptying methods including normal spontaneous micturition (NSM), micturition with assisted maneuvers (MAM), aseptic intermittent catheterization by patient (IC-P), aseptic IC by an attendant/caregiver (IC-A) and indwelling catheterization.

Design: Cross-sectional.

Setting: Tertiary rehabilitation center.

Participants: Patients referred to Brain and Spinal Cord Injury Research Center between 2012 and 2014.

Outcome measures: HRQoL was assessed by Short Form Health Survey (SF-36). Hierarchical regression analysis with adjustment for probable confounders (demographic and injury-related variables) was performed to assess the relationship between bladder-emptying method and total SF-36 score.

Results: Patients with injury at cervical sections had significantly lower scores in domain of physical functioning (PF), physical component summary (PCS) and total score (P: 0.001, <0.0001 and 0.027, respectively). Longer time since injury was associated with better scores of PCS, Mental component summary (MCS) and total score (P: 0.002, <0.0001 and 0.003, respectively). Regression analysis showed that the effect of bladder-emptying method on total score of SF-36 was significant (P < 0.0001) and this relationship remained significant after adjustment for probable confounders in the second step of hierarchical regression analysis (R: 0.923, R²: 0.852, Adjusted R²: 0.847, P?<?0.0001). Patients with NSM had the highest scores in SF-36 instrument and individuals with indwelling catheterization had the poorest HRQoL in all domains.

Conclusion: This study shows that the type of bladder management method affects HRQoL significantly in patients with SCI. Intermittent catheterization are recommended to be administered instead of indwelling catheterization to improve HRQoL.
