RESUMEN
Background: Diabetic peripheral neuropathy (DPN) is a leading cause of morbidity. This systematic review and meta-analysis evaluate the efficacy of lower extremity nerve decompression in reducing DPN symptoms and complications. Methods: A database search was performed using Medline, Embase, Google Scholar, and Cochrane Central Register of Controlled Trials. Articles addressing surgical decompression of lower limb peripheral nerves in patients with diabetes were screened for inclusion. Two independent reviewers undertook the assessment. Methodological quality measures were the Cochrane risk of bias and Newcastle-Ottawa scale. Results: The pooled sample size from 21 studies was 2169 patients. Meta-analysis of 16 observational studies showed significant improvement in the visual analog scale (VAS) (P < 0.00001) and two-point discrimination (P = 0.003), with strong reliability. Decompression of the tarsal tunnel region had the highest improvement in VAS [MD, 6.50 (95% CI, 3.56-9.44)]. A significant low-risk ratio (RR) of ulcer development and lower limb amputation was detected (P < 0.00001). Lowest RR of ulcer development was detected with tarsal tunnel release [RR, 0.04 (95% CI, 0.00-0.48)]. Improvements in VAS, two-point discrimination, and nerve conduction velocity were nonsignificant in the meta-analysis of five randomized controlled trials (RCTs). The RCT analysis was limited to only two studies for each outcome. Conclusions: Meta-analysis of observational studies highlights the efficacy of lower extremity nerve decompression in reducing DPN symptoms, ulcerations, and amputations. Releasing the tibial nerve in the tarsal tunnel region was the most effective observed procedure. Nevertheless, high-quality RCTs are required to support the utility of this intervention in DPN.
RESUMEN
OBJECTIVE: Body dysmorphic disorder (BDD) represents a bridge between the fields of psychiatry and cosmetic surgery. It is a psychiatric disorder involving altered body image and has been associated with cosmetic surgery. Many studies have investigated BDD following rhinoplasty. However, their findings were inconsistent, which prompted us to conduct this systematic review to obtain strong evidence about the prevalence of BDD among rhinoplasty candidates. METHODS: We searched the literature using electronic databases such as PubMed, Scopus, Web of Science, and others using keywords relevant to the study outcomes. We also manually examined the references of the included studies and relevant reviews to look for articles that might have been missed during the electronic search. RESULTS: Nine articles met the inclusion criteria. We identified 7 other relevant articles; since they had been included in a review conducted in 2016, they were not included in the final list of articles. However, they were included in the discussion, and their findings have been compared with ours. The included articles resulted in a total sample of 712 rhinoplasty candidates. The estimated prevalence rates of BDD in these articles ranged from 22% to 52%, which was considered high by all the authors of the included studies. CONCLUSION: The prevalence of BDD among rhinoplasty candidates is high, and adequate management and interventions are needed to reduce it.
