Low back pain related to a sacral insufficiency fracture: role of paravertebral oxygen-ozone therapy in a paradigmatic case of nociplastic pain.

We describe the case of a 68-year-old woman with an acute episode of severe low back pain (LBP) resistant to opioids, who had experienced a sacral insufficiency fracture (SIF) two years earlier. At clinical examination, patient reported constant, dull, non-localizable pain at lumbar and sacral level, exacerbated by paravertebral palpation, particularly at L4-L5 and the sacroiliac joint, with a concomitant and remittent neuropathic component, difficult to localize at lumbar and sacral level. The latest magnetic resonance imaging study revealed disc herniations at L3-L4, L4-L5, and L5-S1 levels. The patient was treated with intramuscularparavertebral injections of oxygen-ozone (O2O3) mixture for 4 weeks (once a week), using a O3 concentration of 20 mcg/mL (5 mL in L4-L5 zone and 5 mL in L5-S1 zone, bilaterally). At 1 week after the first injection, the pain (assessed by Numerical Pain Rating Scale and Brief Pain Inventory) was considerably reduced and the patient's health-related quality of life (assessed by Short Form 12-Item Health Survey and European Quality of Life Index) had improved; these findings were confirmed at follow-up 1 month after the last injection. This paradigmatic case of nociplastic pain successfully treated by paravertebral O2O3 therapy might be a starting point for further studies on the effects of this treatment in terms of decreasing pain and improving HRQoL in patients affected by opioid-resistant LBP.

Are Dietary Supplements and Nutraceuticals Effective for Musculoskeletal Health and Cognitive Function? A Scoping Review.

OBJECTIVE: The aim of our scoping review was to summarize the state of the art regarding micronutrients in order to identify which of them might effectively improve health status in the areas typically impaired in older people: bone, skeletal muscle, and cognitive function. DESIGN: Scoping review. METHODS: The Italian Study Group on Healthy Aging by Nutraceuticals and Dietary Supplements (HANDS) performed this scoping review, based on the following steps: doing a list of micronutrients related with musculoskeletal or cognitive functions, included in dietary supplements and nutraceuticals commercialized in Italy; planning a research on PubMed, according to an evidence-based approach, in order to the most relevant positive study for each micronutrient into each of the three areas involved (bone, skeletal muscle and cognitive function); identifying the micronutrients effective in maintaining or achieving an adequate health status in older people, specifying the effective and safe daily doses, according to the selected studies. RESULTS: In literature we found 12 relevant positive studies (1 international society guidelines/recommendations, 1 systematic review, 7 randomized controlled trials, and 3 prospective cohort studies). We showed that only 16 micronutrients resulted to have appropriate scientific evidences in terms of improving musculoskeletal health and/or cognitive function in older people: beta-alanine, calcium, creatine, fluorides, leucine, magnesium, omega-3 fatty acids, potassium, vitamin B6, vitamin B9, vitamin B12, vitamin C, vitamin D, vitamin E, vitamin K2, and zinc. CONCLUSION: This scoping review showed that selected micronutrients in adequate doses might have an ancillary role in musculoskeletal health and cognitive functions in older people.
