Anesthesia for ophthalmic surgery: an educational review.

Selecting an anesthetic agent for ophthalmic surgery has crucial implications for the surgeon, anesthesiologist, and patient. This educational review explores the common classes of anesthesia used in ophthalmology. Additionally, we discuss the considerations unique to cataract, glaucoma, strabismus, orbital, oculoplastic, and ocular trauma surgeries.

Slow and Steady But Not Related to HIV Stigma: Physical Activity in South Africans Living with HIV and Chronic Pain.

HIV stigma may influence physical activity in people living with HIV (PLWH) and chronic pain. We prospectively examined the relationship between stigma, activity and chronic pain in a convenience sample of PLWH initiating antiretroviral therapy in an inner-city clinic in Johannesburg, South Africa. Participants wore accelerometers to measure daily duration and intensity of activity for 2 weeks. Stigma was assessed with the Revised HIV Stigma Scale. Participants [n = 81, 89% female, age mean (SD) 42 (8)] were active for a median of 7 h daily (IQR 5.2, 9.2), but at very low intensity, equivalent to a slow walk [median (IQR): 0.39 m s (0.33, 0.50)]. Duration and intensity of activity was not associated with stigma, even after controlling for age, self-assessed wealth, pain intensity and willingness to engage in physical activity (p-values > 0.05). As stigma did not associate with greater activity, drivers of sustained activity in South African PLWH remain unclear.

Keratinocyte TLR2 and TLR7 contribute to chronic itch through pruritic cytokines and chemokines in mice.

Although neuronal Toll-like receptors (TLRs) (e.g., TLR2, TLR3, and TLR7) have been implicated in itch sensation, the roles of keratinocyte TLRs in chronic itch are elusive. Herein, we evaluated the roles of keratinocyte TLR2 and TLR7 in chronic itch under dry skin and psoriasis conditions, which was induced by either acetone-ether-water treatment or 5% imiquimod cream in mice, respectively. We found that TLR2 and TLR7 signaling were significantly upregulated in dry skin and psoriatic skin in mice. Chronic itch and epidermal hyperplasia induced by dry skin or psoriasis were comparably reduced in TLR2 and TLR7 knockout mice. In the dry skin model, the enhanced messenger RNA (mRNA) expression levels of pruritic CXCL1/2, IL-31, IL-33, ST2, IL-6, IL-17A, TNF-α, and IFN-γ were inhibited in TLR2 mice, while CXCL2, IL-31, and IL-6 were inhibited in TLR7 mice. In psoriasis model, the enhanced mRNA expression levels of pruritic CXCL1/2, IL-31, IL-33, ST2, IL-6, and TNF-α were inhibited in TLR2 mice, while CXCL1/2, IL-31, IL-33, ST2, IL-6, IL-17A, and TNF-α were inhibited in TLR7 mice. Incubation with Staphylococcus aureus (S. aureus) peptidoglycan (PGN-SA) (a TLR2 agonist), imiquimod (a TLR7 agonist), and miR142-3p (a putative TLR7 agonist) were sufficient to upregulate the expression of pruritic cytokines or chemokines in cultured keratinocyte HaCaT cells. Finally, pharmacological blockade of C-X-C Motif Chemokine Receptor 1/2 and high mobility group box protein 1 dose-dependently attenuated acute and chronic itch in mice. Together, these results indicate that keratinocyte TLR2 and TLR7 signaling pathways are distinctly involved in the pathogenesis of chronic itch.

Opioid versus non-opioid analgesia for spine surgery: a systematic review and meta-analysis of randomized controlled trials.

Opioids are the primary analgesics used in patients undergoing spine surgery. Postoperative pain is common despite their liberal use and so are opioid-associated side effects. Non-opioid analgesics are gaining popularity as alternative to opioids in spine surgery.

Comparative Efficacy of the Stromal-Vascular Fraction Cells of Lipoaspirate and Hyaluronic Acid in the Treatment of Gonarthrosis: Results of an Interim Analysis.

The use of cell technologies, in particular the stromal-vascular fraction of adipose tissue, is a new direction in the treatment of osteoarthritis of the weight-bearing joints. Stromal-vascular fraction cells have anti-inflammatory and immunomodulatory effects and are able to differentiate into connective tissue cells, including cartilage, tendons, and ligaments. Our clinical study showed the safety and good tolerability of intra-articular administration of autologous stromal-vascular fraction cells in 16 patients with severe manifestations of osteoarthritis. Single administration of stromal-vascular fraction cells led to more pronounced and stable (up to 12 months) clinical improvement in the main symptoms of the disease, including pain and functional activity of the affected joints, in comparison with intra-articular injection of hyaluronic acid (10 patients of the comparison group).

The Ethanol Extract of Syringa oblata Heartwood, a Mongolian Folk Medicine Containing Major Lignans, Exerts the Analgesic and Sedative Effects on Mice.

The heartwood of Syringa oblata Lindl. (SO) is one of Mongolian folk medicine to treat insomnia and pain, but related pharmacological evaluation and mechanism of action remains unclear. In the present study, the locomotor activity test and the threshold dose of pentobarbital sodium induced sleep test in mice were used to evaluate the sedative effect of ethanol extract of SO (ESO), and the hot plate test, acetic acid-induced writhing test and formalin test in mice were to evaluate the analgesic effect. The underlying mechanism of ESO analgesia was explored by RT-PCR and western blot analysis that associated with the regulation of NF-κB signaling pathway. Besides, the main constituents of ESO were characterized by LC-MS data analysis and comparison with isolated pure compounds. The current findings brought evidence for clinical application and further pharmacological and phytochemical studies on SO.

Development of Primary Palliative Care End-of-Life Quality Measures: A Modified Delphi Process.

Children with complex chronic conditions (CCCs) and their families deserve high-quality pediatric palliative care (PPC) throughout their illness trajectory, including at end of life (EOL). Standard EOL quality measures (QM) have only recently been proposed, require surveys and/or manual chart review, and focus on children with cancer. Therefore, we aimed to develop expert-endorsed, hospital-based, primary PPC quality measures for EOL care for all children with CCCs that could be automatically abstracted from the electronic health record (EHR).

Intravenous lidocaine infusion compared to thoracic epidural analgesia in cytoreductive surgery with or without heated intraperitoneal chemotherapy. A retrospective case-cohort study.

Intravenous (IV) lidocaine is a proven analgesic therapy but has not been evaluated in extensive procedures such as cytoreductive surgery (CRS). Our aim was to assess the effectiveness and safety of IV lidocaine in this setting.

Impact of Long-Term Evoked Compound Action Potential Controlled Closed-Loop Spinal Cord Stimulation on Sleep Quality in Patients With Chronic Pain: An EVOKE Randomized Controlled Trial Study Subanalysis.

Spinal cord stimulation (SCS) is considered an effective interventional nonpharmacologic treatment option for several chronic pain conditions. Here we present the effects of the novel evoked compound action potential (ECAP) controlled closed-loop (ECAP-CL) SCS system on long-term sleep quality outcomes from the EVOKE study.
