Joint infection might be one of the rare but serious complications following a total knee or hip arthroplasty (TKA, THA). A previous intra-articular steroid injection was considered as a risk factor. The purpose of present study was to access the effects of ipsilateral intra-articular steroid injection followed by TKA or THA on the incidence of infections later. ⋯ No increased risk of infection among patients who received steroid injections prior to the surgery was identified from the present evidence. A multicenter prospective study with more defined variables is needed further investigate this issue.

Randomized Controlled Trial Comparative Study
Pyriform sinus localization-assisted blind intubation: comparison with laryngoscopic intubation.
Conventional endotracheal intubation requires laryngoscopy for a direct view of the glottis. However, laryngoscopy is associated with many potential complications. The aim of the present study was to compare the efficacy and safety of pyriform sinus localization-assisted blind orotracheal intubation with those of conventional laryngoscopic orotracheal intubation. ⋯ Pyriform sinus localization-assisted blind orotracheal intubation was shown to be more effective than conventional laryngoscopic orotracheal intubation in terms of success rate, intubation time, and postoperative complication rate. Moreover, it is less affected by common risk factors; thus, this method may be more beneficial in patients with difficult airways.

Cumulating evidence indicated that nerve injury-associated cellular and molecular changes play an essential role in contributing to the development of pathological pain, and more recent findings implicated the critical role of epigenetic mechanisms in pain-related sensitization in the DRG subsequent to nerve injury. In this part of the dyad review (Part II), we reviewed and paid special attention on the etiological contribution of DGR gene expression modulated by epigenetic mechanisms of CRPS. As essential effectors to different molecular activation, we first discussed the activation of various signaling pathways that subsequently from nerve injury, and in further illustrated the fundamental and functional underpinnings of nerve injury-induced pain, in which we argued for the potential epigenetic mechanisms in response to sensitizing stimuli or injury. Therefore, understanding the specific mediating factors that influence individual epigenetic differences contributing to pain sensitivity and responsiveness to analgesics possesses crucial clinical implications.

Effect of electroacupuncture at Zusanli (ST36) and Sanyinjiao (SP6) acupoints on adrenocortical function in etomidate anesthesia patients.
We aimed to investigate the effect of electroacupuncture at Zusanli (ST36) and Sanyinjiao (SP6) on adrenocortical function in patients with etomidate anesthesia. ⋯ Electroacupuncture at ST 36 and SP 6 can mitigate the adrenal cortical inhibition induced by etomidate and can reduce the secretion of catecholamines during surgery.

DRG is of importance in relaying painful stimulation to the higher pain centers and therefore could be a crucial target for early intervention aimed at suppressing primary afferent stimulation. Complex regional pain syndrome (CRPS) is a common pain condition with an unknown etiology. Recently added new information enriches our understanding of CRPS pathophysiology. ⋯ In this part, we first reviewed and summarized the role of neural sensitization in DRG neurons in performing function in the context of pain processing. Particular emphasis is placed on the cellular and molecular changes after nerve injury as well as different models of inflammatory and neuropathic pain. These were considered as the potential molecular bases that underlie nerve injury-associated pathogenesis of CRPS.
