Although recent studies have shown that botulinum toxin-A (BTX-A) has a good analgesic effect on trigeminal neuralgia (TN) and peripheral neuropathic pain (PNP), the quality of evidence is low due to limited data. This meta-analysis is used to synthesize existing evidence for the treatment of these conditions with BTX-A. ⋯ Pooled data from our meta-analysis suggest that BTX-A is efficacious and safe in treating TN and PNP. However, due to the limited sample size and heterogeneity, further larger and well-designed RCTs are imperative to validate these findings.

Neuropathic pain can be a predictor of severe emotional distress, up to full-blown depressive states. In these patients, it is important to move beyond the sole treatment of pain, to recognize depressive symptoms, and to ultimately improve the quality of life. We systematically searched for published and unpublished clinical trials assessing the efficacy and tolerability of antidepressants vs placebo on depression, anxiety and quality of life in patients with neuropathic pain, and pooled data in a meta-analysis. ⋯ To the best of our knowledge, this is the first meta-analysis specifically focusing on the effect of antidepressants on psychiatric symptoms and quality of life in patients with neuropathic pain. Our findings suggest that despite their potential benefit in patients with neuropathic pain, antidepressants should be prescribed with particular care because they might be less tolerable in such a fragile population. However, our findings warrant further research to explore how a correct use of antidepressants can help patients to cope with the consequences of neuropathic pain on their psychosocial health and quality of life.

Controversy still exists regarding the efficiency and safety of ilioinguinal/iliohypogastric nerve (II/IH) block versus transversus abdominis plane (TAP) block for pain management after inguinal hernia repair. The purpose of the current meta-analysis was to perform a relatively credible and comprehensive assessment to compare the efficiency and safety of II/IH versus TAP for pain management after inguinal hernia repair. ⋯ In general, this meta-analysis revealed that both approaches have similar postoperative opioid consumption and no significant difference in postoperative complication and patient satisfaction. The II/IH block provides excellent analgesic effects at 6 and 8 hours after inguinal herniorrhaphy in compared with the TAP block. However, more high-quality randomized controlled trials with long-term follow-up are still required to make the conclusion.

Meta AnalysisAcetyl-L-carnitine for the treatment of diabetic peripheral neuropathy.
Diabetic peripheral neuropathy (DPN) is a common and severe complication that affects 50% of people with diabetes. Painful DPN is reported to occur in 16% to 24% of people with diabetes. A complete and comprehensive management strategy for the prevention and treatment of DPN, whether painful or not, has not yet been defined.Research into treatment for DPN has been characterised by a series of failed clinical trials, with few noteworthy advances. Strategies that support peripheral nerve regeneration and restore neurological function in people with painful or painless DPN are needed. The amino acid acetyl-L-carnitine (ALC) plays a role in the transfer of long-chain fatty acids into mitochondria for β-oxidation. ALC supplementation also induces neuroprotective and neurotrophic effects in the peripheral nervous system. Therefore, ALC supplementation targets several mechanisms relevant to potential nerve repair and regeneration, and could have clinical therapeutic potential. There is a need for a systematic review of the evidence from clinical trials. ⋯ We are very uncertain whether ALC causes a reduction in pain after 6 to 12 months' treatment in people with DPN, when compared with placebo, as the evidence is sparse and of low certainty. Data on functional and sensory impairment and symptoms are lacking, or of very low certainty. The evidence on adverse events is too uncertain to make any judgements on safety.

Meta AnalysisProgression of Neuropathic Pain after Acute Spinal Cord Injury: A Meta-Analysis and Framework for Clinical Trials.
The translation of therapeutic interventions to humans with spinal cord injury with the goal of promoting growth and repair in the central nervous system could, inadvertently, drive mechanisms associated with the development of neuropathic pain. A framework is needed to evaluate the probability that a therapeutic intervention for acute spinal cord injury modifies the progression of neuropathic pain. We analyzed a large, longitudinal dataset from the European Multi-Center Study about Spinal Cord Injury (EMSCI) and compared these observations with a previously published Swedish/Danish cohort. ⋯ Characteristics that were significantly associated with the progression of pain included age and sensory and motor preservation. We provide historical benchmarks for estimating the progression of neuropathic pain during the first year after acute SCI. This information will be useful for comparison and evaluating safety during early phase acute spinal cord injury trials.
