ABSTRACT

CONTEXT/OBJECTIVE: To identify circumstances surrounding incident lower extremity fractures (ILEFs) in patients with spinal cord injury (SCI) and to describe the impact of these fractures on service needs and provision of pharmacological therapies for osteoporosis. DESIGN: Retrospective medical record review. SETTING: Four Veterans Affairs Medical Centers in the USA. PARTICIPANTS: One hundred and forty patients with traumatic SCI who sustained an ILEF from 2002 to 2007. OUTCOME MEASURES: Fracture circumstances and use of assistive devices were described using percentages, means, and standard deviations. Fisher's exact test was used to determine the relationship between fracture site, and patient age and duration of SCI. Differences in pharmacological provision of therapies for osteoporosis pre- and post-fracture were examined using exact McNemar's test. RESULTS: One hundred and fifty-five ILEFs were identified in 140 patients. Tibia/fibula and femur fractures were the most common fractures. Fracture site was not related to patient's age or duration of SCI. Almost one-third of all fractures occurred during transfers to and from wheelchairs. Post-fracture, the provision of new or modified assistive devices, primarily wheelchairs, was frequent, occurring in 83% of patients in the year post-fracture. Few patients transferred residence to a nursing home following the fracture. There was a significant difference in the use of pharmacological therapies for osteoporosis in the first year post-fracture compared with the year prior to the fracture (P < 0.01), with significant differences in the volume of prescriptions for calcium supplements (P < 0.01) and bisphosphonates (P = 0.02). Overall, the amount of prescriptions for osteoporosis increased the year post-fracture (56%) from the year pre-fracture (39%); this increase was secondary to increases in prescriptions for calcium supplements (pre = 13%; post = 30%) and bisphosphonates (pre = 2%; post = 7%). CONCLUSIONS: We have identified that wheelchair and other transfer activities are a key area that could be a focus of fracture prevention in SCI. The need for new or modified assistive devices and/or wheelchair skills retraining post-fracture should be anticipated. Examination of whether treatments for osteoporosis following a fracture can prevent future osteoporotic fractures is warranted.

ABSTRACT

OBJECTIVE: The aim of this study was to determine whether anticonvulsants, including the benzodiazepine subclass, are associated with an increased risk for lower extremity fractures in male patients with spinal cord injury. DESIGN: All male patients with a history of a traumatic spinal cord injury of 2 yrs' duration or longer in the Veterans Affairs Spinal Cord Disease Registry from 2002 to 2007 were included. Incident lower extremity fractures during this period and anticonvulsant use were identified. The association of anticonvulsant use, overall, by type (enzyme inducing, non-enzyme inducing), by number (monotherapy vs. polytherapy), by benzodiazepine subclass, and by individual medication used was determined. RESULTS: In this cohort, 892 veterans sustained a fracture, and 6555 did not. Compared with nonusers of anticonvulsants, there was a significant positive relationship with fractures by overall use of anticonvulsants (HR, 1.17 [95% CI, 1.01-1.36]), by users of the benzodiazepine subclass (HR, 1.28 [95% CI, 1.11-1.47]), and by polytherapy compared with monotherapy (HR, 1.20 [95% CI, 1.00-1.42]) but not by anticonvulsant type (HR, 0.92 [95% CI, 0.58-1.47]). Temazepam (HR, 1.28 [95% CI, 1.01-1.62]), alprazolam (HR, 1.54 [95% CI, 1.04-2.29]), and diazepam (HR, 1.23 [95% CI, 1.06-1.41]) were significantly positively associated with fractures. CONCLUSIONS: Attention to fracture prevention is important when anticonvulsants are prescribed in spinal cord injury, particularly when more than one anticonvulsant is used.

ABSTRACT

OBJECTIVE: To determine the association between opioid use and lower extremity fracture risk in men with spinal cord injury (SCI). DESIGN: Retrospective cohort study. SETTING: Veterans Affairs Healthcare System. PARTICIPANTS: In total, 7447 male Veterans with a history of a traumatic SCI identified from the Veterans Affairs (VA) Spinal Cord Dysfunction Registry (SCD) from September 2002 through October 2007 and followed through October 2010. OUTCOME MEASURES: Incident lower extremity fractures by use of opioids. RESULTS: In individuals identified from the VA SCD Registry 2002-2007, opioid use was quite common, with approximately 70% of the cohort having received a prescription for an opioid. Overall, there were 892 incident lower extremity fractures over the time period of this study (597 fractures in the opioid users and 295 fractures in the non-opioid users). After adjusting for covariates, there was a statistically significant relationship between opioid use and increased risk for lower extremity fractures (hazard ratio 1.82 (95% confidence interval 1.59-2.09)). Shorter duration of use (<6 months) and higher doses were positively related to fracture risk (P < 0.0001). CONCLUSIONS: Opioid use is quite common in SCI and is associated with an increased risk for lower extremity fractures. Careful attention to fracture prevention is warranted in patients with SCI, particularly upon initiation of an opioid prescription and when higher doses are used.

ABSTRACT

IMPORTANCE OF THE FIELD: Systemic sclerosis (SSc) is an uncommon autoimmune disease with variable degrees of fibroproliferation in blood vessels and certain organs of the body. There is currently no cure. The purpose of this article is to review the current literature regarding pathogenesis and treatment of complications of SSc. AREAS COVERED IN THIS REVIEW: All available articles regarding research related to SSc pathogenesis and treatment listed in the PubMed database were searched; relevant articles were then reviewed and used as sources of information for this review. WHAT THE READER WILL GAIN: This review attempts to highlight for the reader some current thought regarding mechanisms of SSc pathogenesis and how autoimmunity relates to vascular changes and fibrogenesis of the disease, as well as providing a review of results of completed clinical trials and current ongoing clinical trials that address organ-specific or global therapies for this disease. This can aid physicians who provide medical care for patients with SSc. TAKE HOME MESSAGE: SSc is a complex autoimmune disease, the pathogenesis of which, although not completely understood, is under active study; new insights into pathogenesis are continually being discovered. Although there is no effective disease-modifying treatment for patients with SSc, quality of life, morbidity and mortality can be improved by using targeted therapy directed at affecting the consequences of damage to lungs, blood vessels, kidneys and the gastrointestinal tract. Innovative approaches to treating SSc are under intense investigation.
