The value of perforator flap reconstruction in painful soft tissue calcifications.

Soft tissue calcifications frequently cause debilitating pain and functional impairments, considerably affecting patients' quality of life. As they are rare entities, evidence remains sparse, especially regarding treatment effectiveness and recurrence rates. While both pharmacological and surgical treatments may alleviate symptoms, complete resection is currently believed to prevent long-term recurrence of deposits. To improve understanding and raise awareness for soft tissue calcifications, the goal of this study was to review the current state of treatment and to compare benefits and possibilities of flap reconstruction versus simple excision in improving quality of life. Furthermore, we include a successful case report of complete resolution of symptoms following quadruple perforator flap reconstruction. By systematic literature review, studies published in MEDLINE between 1980 and 2024 reporting on surgical treatment and outcome of soft tissue calcifications were included, in addition to a detailed description of our case report. A total of 53 studies reporting on 197 patients with soft tissue calcifications were included. Simple surgical excision was the most commonly (85.9%) employed procedure, demonstrating a substantial recurrence rate of 13.3%. In contrast, no patients who underwent radical excision experienced recurrence. Dermal matrix grafts and flap reconstruction were successfully used in patients requiring substantial tissue coverage, highlighting their value in complex defect reconstruction following radical excision. The combination of complete surgical resection and flap reconstruction reduces recurrence rates and improves postoperative outcomes and quality of life of these patients, supporting early radical surgical intervention as the gold standard treatment for soft tissue calcifications.

Prevention of nonvertebral fractures with oral vitamin D and dose dependency: a meta-analysis of randomized controlled trials.

BACKGROUND: Antifracture efficacy with supplemental vitamin D has been questioned by recent trials. METHODS: We performed a meta-analysis on the efficacy of oral supplemental vitamin D in preventing nonvertebral and hip fractures among older individuals (> or =65 years). We included 12 double-blind randomized controlled trials (RCTs) for nonvertebral fractures (n = 42 279) and 8 RCTs for hip fractures (n = 40 886) comparing oral vitamin D, with or without calcium, with calcium or placebo. To incorporate adherence to treatment, we multiplied the dose by the percentage of adherence to estimate the mean received dose (dose x adherence) for each trial. RESULTS: The pooled relative risk (RR) was 0.86 (95% confidence interval [CI], 0.77-0.96) for prevention of nonvertebral fractures and 0.91 (95% CI, 0.78-1.05) for the prevention of hip fractures, but with significant heterogeneity for both end points. Including all trials, antifracture efficacy increased significantly with a higher dose and higher achieved blood 25-hydroxyvitamin D levels for both end points. Consistently, pooling trials with a higher received dose of more than 400 IU/d resolved heterogeneity. For the higher dose, the pooled RR was 0.80 (95% CI, 0.72-0.89; n = 33 265 subjects from 9 trials) for nonvertebral fractures and 0.82 (95% CI, 0.69-0.97; n = 31 872 subjects from 5 trials) for hip fractures. The higher dose reduced nonvertebral fractures in community-dwelling individuals (-29%) and institutionalized older individuals (-15%), and its effect was independent of additional calcium supplementation. CONCLUSION: Nonvertebral fracture prevention with vitamin D is dose dependent, and a higher dose should reduce fractures by at least 20% for individuals aged 65 years or older.
