RESUMO
AIMS: To assess the efficacy of surgical decompression of lower extremity nerves for the treatment of painful diabetic peripheral sensorimotor polyneuropathy (DPN). METHODS: People with painful diabetic neuropathy were randomized single-blind to a lower extremity decompression surgery (nâ¯=â¯12) or observation (nâ¯=â¯10) for 1â¯year. RESULTS: Pain was the primary outcome assessed with 2 measures. The McGill pain visual analogue scores over time changed within the groups (p for timeâ¯<â¯0.0001), and changed differently over time within the groups (p for groupâ¯×â¯timeâ¯=â¯0.0138). The NeuroQoL pain sensitivity analysis significantly changed from baseline to 12â¯months comparing intervention to control (pâ¯=â¯0.0079), and the joint effect of group and time on pain scores was statistically significant (p for groupâ¯×â¯timeâ¯=â¯0.0009). At the study end-point of 12â¯months, intervention group participants had over 3 times the odds of rating their pain as "better" compared to "unchanged" or "worse" in the control group (pâ¯=â¯0.0177). CONCLUSIONS: Surgical decompression of lower limb nerves was an effective treatment for decreasing pain in patients with DPN and superimposed nerve compressions.

BACKGROUND: Osteoporosis-related fractures are a significant public health concern. Interventions that increase detection and treatment of osteoporosis are underutilized. This pragmatic randomised study was done to evaluate the impact of a multifaceted community-based care program aimed at optimizing evidence-based management in patients at risk for osteoporosis and fractures. METHODS: This was a 12-month randomized trial performed in Ontario, Canada. Eligible patients were community-dwelling, aged ≥55 years, and identified to be at risk for osteoporosis-related fractures. Two hundred and one patients were allocated to the intervention group or to usual care. Components of the intervention were directed towards primary care physicians and patients and included facilitated bone mineral density testing, patient education and patient-specific recommendations for osteoporosis treatment. The primary outcome was the implementation of appropriate osteoporosis management. RESULTS: 101 patients were allocated to intervention and 100 to control. Mean age of participants was 71.9 ± 7.2 years and 94% were women. Pharmacological treatment (alendronate, risedronate, or raloxifene) for osteoporosis was increased by 29% compared to usual care (56% [29/52] vs. 27% [16/60]; relative risk [RR] 2.09, 95% confidence interval [CI] 1.29 to 3.40). More individuals in the intervention group were taking calcium (54% [54/101] vs. 20% [20/100]; RR 2.67, 95% CI 1.74 to 4.12) and vitamin D (33% [33/101] vs. 20% [20/100]; RR 1.63, 95% CI 1.01 to 2.65). CONCLUSIONS: A multi-faceted community-based intervention improved management of osteoporosis in high risk patients compared with usual care. TRIAL REGISTRATION: This trial has been registered with clinicaltrials.gov (ID: NCT00465387).
