There is increasing interest in outpatient shoulder arthroplasty (SA); however, the clinical evidence behind this practice is sparse. The purpose of this study was to assess the safety of outpatient SA performed in an ambulatory surgery center and to determine patient factors that are associated with increased risk for perioperative complications or dissatisfaction.

Thermo-nociception, the detection and behavioral response to noxious temperatures, is a highly conserved action to avoid injury and ensure survival. Basic molecular mechanisms of thermal responses have been elucidated in several model organisms and are of clinical relevance as thermal hypersensitivity (thermos-allodynia) is common in neuropathic pain syndromes. larvae show stereotyped escape behavior upon noxious heat stimulation, which can be easily quantified and coupled with molecular genetic approaches. It has been successfully used to elucidate key molecular components and circuits involved in thermo-nociceptive responses. We provide a detailed and updated protocol of this previously described method ( Tracey , 2003 ) to apply a defined local heat stimulus to larvae using a fast-regulating hot probe.

larvae have been extensively used as a model to study the molecular and cellular basis of nociception. The larval nociceptors, class IV dendritic arborization (C4da) neurons, line the body wall of the animal and respond to various stimuli including noxious heat and touch. Activation of C4da neurons results in a stereotyped escape behavior, characterized by a 360° rolling response along the body axis followed by locomotion speedup. The genetic accessibility of has allowed the identification of mechanosensory channels and circuit elements required for nociceptive responses, making it a useful and straightforward readout to understand the cellular and molecular basis of nociceptive function and behavior. We have optimized the protocol to assay mechanonociceptive behavior in larvae.

Flecainide acetate is a drug used primarily for cardiac arrhythmia. Some studies also imply that flecainide acetate has the potential to regulate inflammatory-immune responses; however, its mechanism of action is contended. We determined the effects of flecainide acetate on lipopolysaccharide (LPS)-stimulated human neutrophils in vitro and on mortality in a septic rat model.

Practices to support the transition of a young person from the pediatric to the adult health care setting have been examined for many chronic illness populations. However, specific transition practices to support young people with chronic pain have not been examined.

Intravitreal silicon oil removal surgery can cause mild-to-moderate postoperative pain and discomfort in most patients. Postoperative pain can be managed by using many methods, including a local anesthetic drug. One of the common local anesthetic drugs is 0.5% bupivacaine. The application techniques also vary, such as subconjunctival application. It was a good alternative for postoperative analgesia in the ophthalmic surgery because of its minimal risks and complications. The purpose of this research was to measure the effectiveness of subconjunctival 0.5% bupivacaine for postoperative analgesia in silicon oil removal surgery.

It is known that the epigenetic process of histone acetylation is involved in the neuropathic pain. The aim of this study was to determine whether sirtuin type 1 (SIRT1), an NAD dependent deacetylase, affected allodynia and hyperalgesia in neuropathic pain. The neuropathic pain model was established by ligature of the right sciatic nerve to induce chronic constriction injury (CCI) in rats. Histone acetyltransferase (HAT) activity was increased and, and histone deacetylase (HDAC) activity was declined in tissue of the spinal dorsa horn in CCI rates by means of enzyme-linked immunosorbent assay (ELISA). The persistent hyperalgesia and allodynia caused by CCI were associated with downregulation of SIRT1 and upregulation of acetylated-H3 (Ac-H3) in tissue of the spinal cord by Western blot assay, which was reversed after intrathecal injection of SIRT1 agonist SRT1720. SRT1720 treatment achieved analgesic through inhibiting the acetylation of nuclear factor kappa B (NF-κB) and blocking the releases of the inflammatory factors including tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 by means of Western blot and real-time quantitative PCR (RT-PCR), respectively. Taken together, these data suggest that SIRT1 in the spinal cord plays an important role in the neuropathic pain in the rat model.

The biopsychosocial model claims that illness is generated by both biological and psychosocial factors. Accordingly, several studies have shown that both factors contribute to the generation of pain.

Apremilast is used as a systemic therapy for the treatment of psoriasis and psoriatic arthritis. This drug is considered relatively safe with a very low incidence of serious side effects. Common side effects are diarrhea, nausea, headache, nasopharyngitis, upper respiratory tract infections which are mild to moderate in severity. Diarrhea tends to occur within 2 weeks of starting treatment and resolve spontaneously within 4 weeks without dose adjustment or discontinuation of therapy. Chronic diarrhea and malnutrition due to apremilast have not been reported yet. We report a case of apremilast induced chronic diarrhea leading to malnutrition, necessitating discontinuation of therapy.
