To describe our contemporary experience with aspiration and sclerotherapy (AS) as a non-surgical alternative for patients with symptomatic hydrocele and spermatocele who prefer non-surgical treatment.

To evaluate the outcomes of a narcotic-sparing clinical pathway after robotic-assisted radical cystectomy (RARC) with ileal conduit targeting discharge on postoperative day #2 and report postoperative narcotic consumption, pain scores, and the resulting length of stay (LOS).

To analyze the National Hospital Ambulatory Medical Care Survey (NHAMCS) database to determine geographic and temporal trends, as well as variables associated with the likelihood of receiving an opioid prescription for urolithiasis in US EDs.

To investigate the bidirectional relationship by determining whether baseline sleep quality predicts pain intensity and whether baseline pain intensity predicts sleep quality in older people with chronic LBP.

To assess the antinociceptive efficacy and safety of neuraxial morphine in inland bearded dragons (Pogona vitticeps).

There is evidence in the literature for high-fidelity in situ simulation training programs being an effective modality for physicians training. This quality initiative focused on implementation of the procedural sedation and analgesia (PSA) in our pediatric emergency department (PED). The primary outcomes of this study were to evaluate the impact of blended in situ simulation training (BST) program on PSA for closed forearm fracture reduction in the PED and to assess its cost-effectiveness. The secondary outcomes were to estimate this change on PSA's clinical efficacy and safety.

Caesarean delivery is common and can cause severe postoperative pain but injection of local anaesthetic at various sites for regional blocks or local anaesthetic infiltration may reduce this. We aimed to compare and rank these sites. We searched PubMed, Google Scholar, EMBASE and CENTRAL to June 2021 for randomised controlled trials and performed a random-effects Bayesian model network meta-analysis. The primary outcome was dose of parenteral morphine equivalents in the first 24 postoperative hours. We used surface under cumulative ranking probabilities to order techniques. We analysed 114 trials (8730 participants). The ordered mean (95% credible interval) reduction in morphine equivalents, from 34 mg with placebo, were as follows: ilio-inguinal 15 (1-32) mg; ilio-inguinal-iliohypogastric 13 (6-19) mg; transversalis fascia 11 (4-26) mg; erector spinae 11 (10-32); transverse abdominis 9 (4-13) mg; wound catheter infusion 8 (2-15) mg; quadratus lumborum 8 (1-15) mg; wound infiltration 8 (2-13) mg; and no intervention -4 (-10 to 2) mg. Ordered efficacies for injection sites were different for other relevant outcomes, including pain (to 4-6 h and to 24 h) and time to rescue analgesia: there was no single preferred route of injection. The ordered mean (95% credible interval) reduction in dynamic pain scores (0-10 scale) at 24 h compared with placebo were as follows: wound infusion 1.2 (0.2-2.1); erector spinae 1.3 (-0.5 to 3.1); quadratus lumborum 1.0 (0.1-1.8); ilio-inguinal-iliohypogastric 0.6 (-0.5 to 1.8); transverse abdominis 0.6 (-0.1 to 1.2); wound infiltration 0.5 (-0.3 to 1.3); transversalis fascia -0.8 (-3.4 to 1.9); ilio-inguinal -0.9 (-3.6 to 1.7); and no intervention -0.8 (-1.8 to 0.2). We categorised our confidence in effect sizes as low or very low.

In addition to the symptoms of aging, the main symptoms in Werner syndrome (WS), a hereditary premature aging disease, include calcification of subcutaneous tissue with solid pain and refractory skin ulcers. However, the mechanism of calcification in WS remains unclear. In this study, the histological analysis of the skin around the ulcer with calcification revealed an accumulation of calcium phosphate in the lymphatic vessels. Moreover, the morphological comparison with the lymphatic vessels in PAD patients with chronic skin ulcers demonstrated the ongoing lymphatic remodeling in WS patients because of the narrow luminal cross-sectional area (LA) of the lymphatic vessels but the increment of lymphatic microvessels density (MLVD). Additionally, fluorescence immunohistochemical analysis presented the cytoplasmic distribution and the accumulation of WRN proteins in endothelial cells on remodeling lymphatic vessels. In summary, these results point out a relationship between calcification in lymphatic vessels and the remodeling of lymphatic vessels and suggest the significance of the accumulation of WRN mutant proteins as an age-related change in WS patients. Thus, cytoplasmic accumulation of WRN protein can be an indicator of the decreasing drainage function of the lymphatic vessels and the increased risk of skin ulcers and calcification in the lymphatic vessels.
