Nerve injury-induced aberrant changes in gene expression in spinal dorsal horn neurons are critical for the genesis of neuropathic pain. N6-methyladenine (m 6 A) modification of DNA represents an additional layer of gene regulation. Here, we report that peripheral nerve injury significantly decreased the level of m 6 A-specific DNA methyltransferase 1 ( N6amt1 ) in dorsal horn neurons. ⋯ Rescuing the decrease in N6amt1 reversed the loss of m 6 A at the promoter for inwardly rectifying potassium channel subfamily J member 16 ( Kcnj16 ), mitigating the nerve injury-induced upregulation of Kcnj16 expression in the dorsal horn and alleviating neuropathic pain hypersensitivities. Conversely, mimicking the downregulation of N6amt1 in naive mice erased DNA m 6 A at the Kcnj16 promoter, elevated Kcnj16 expression, and led to neuropathic pain-like behaviors. Therefore, decreased N6amt1 caused by NR2F6 is required for neuropathic pain, likely through its regulation of m 6 A-controlled KCNJ16 in dorsal horn neurons, suggesting that DNA m 6 A modification may be a potential new target for analgesic and treatment strategies.

Oral analgesic for musculoskeletal injuries in children: A systematic review and network meta-analysis.
Pain in pediatric musculoskeletal (MSK) injuries can lead to increased anxiety, fear, and avoidance of medical care, making analgesic management critical. Therefore, we evaluated analgesic efficacy and adverse effects to select the optimal analgesic agent in pediatric patients with MSK injuries. ⋯ Our NMA found ibuprofen to be the most effective and least adverse analgesic in pediatric patients with MSK injuries.

Randomized Controlled TrialAnalgesic efficacy of erector spinae plane block versus paravertebral block in lung surgeries-A non-inferiority randomised controlled trial.
Pain management plays an essential role in postoperative recovery after lung surgeries. The Erector Spinae Plane Block (ESPB) is a widely used regional anaesthesia technique; however, few clinical trials have compared this block to active control in thoracic surgeries. This study evaluated the non-inferiority of the analgesia provided by ESPB when compared to paravertebral block (PVB) in lung surgeries. ⋯ This trial demonstrated that a continuous erector spinae plane block was not non-inferior to a continuous paravertebral block for analgesia after lung surgery but resulted in higher levels of postoperative pain and opioid consumption.

Loxosceles spp are arthropods found worldwide. Its bite may produce cutaneous loxoscelism (necrotic or edematous) or cutaneous-visceral loxoscelism. Depending on their severity and location, cutaneous forms are managed with local cold application and systemic administration of antihistamines, corticosteroids, antibiotics, polymorphonuclear inhibitors, and analgesics. ⋯ PROSPERO ID CRD42023422424 (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023422424).

Acetaminophen is a commonly used analgesic and antipyretic drug, which has experienced an increase in its consumption in recent years in our environment. There has also been an increase in the number of accidental and intentional overdoses that were treated by the health system. Its toxicity is dose-dependent and can cause fulminant liver failure, becoming one of the main reasons for liver transplantation in English-speaking countries. ⋯ She developed fulminant liver failure and metabolic acidosis, for which she underwent an emergency liver transplant due to the severity of her condition, from which she evolved favorably. The decision to perform a liver transplant in serious cases like this and under a condition of severe psychiatric vulnerability is challenging and must be carefully considered. This particular case illustrates the importance of multidisciplinary care including psychiatric evaluation in patients with acetaminophen poisoning.
