The effects of dezocine and sufentanyl on the activity of natural killer (NK), CD4 and CD8 cells in patients with breast cancer undergoing postoperative analgesia after radical mastectomy were compared. The clinical data of 76 female patients undergoing radical mastectomy in the Fudan University Shanghai Cancer Center from January 2015 to October 2017 were analyzed retrospectively. Forty-two patients treated with dezocine were group D and 34 patients with sufentanyl were group S. Visual analogue scale (VAS) was used to evaluate the analgesic effect at 3, 12, 24, 48 h after surgery. There was no significant difference in VAS score, NK cells, CD4 cells, and CD8 cell vitality at 3 h postoperatively between the two groups (P>0.05), and VAS score at 12, 24 and 48 h postoperatively in the S group was significantly lower than that in group D (P<0.05). The activity of NK cells and CD4 cells at 3, 12, 24 and 48 h after surgery in group D was significantly higher than that in group S, and the difference was statistically significant (P<0.05). The activity of CD8 cells at 3, 12, 24 and 48 h after surgery in group D was significantly lower than that in group S, and the difference was statistically significant (P<0.05). The analgesic effect of dezocine was slightly worse than that of sufentanyl, but it was more beneficial to the recovery of early postoperative immune function.

With a growing need for non-opioid chronic pain treatments, pain physicians should understand the proper utilization of neuromodulation therapies to provide the most comprehensive care. We aimed to identify the unmet training needs that deter physicians from using spinal cord stimulation (SCS) devices.

The subspecialty of regional anesthesiology and acute pain medicine (RAAPM) is in a position to lead changes that may impact the current opioid crisis. At the hospital level, RAAPM experts can implement evidence-based multimodal analgesic clinical pathways featuring regional anesthesia. Multimodal analgesia consists of using two or more analgesic modalities targeting pain pathways at various levels to improve pain control, while also aiming to reduce opioid utilization and related adverse effects. These types of pathways or protocols have been widely applied in the joint replacement population. This review focuses on the current state of the evidence regarding individual elements of a multimodal analgesic pathway for patients with total knee arthroplasty including new regional anesthesia techniques like the IPACK (Infiltration between the Popliteal Artery and Capsule of the Knee) block and suggests future research directions to improve the clinical care of this surgical population in the future.

Fibrodysplasia ossificans progressiva (FOP) or myositis ossificans, is a genetic disease, with a prevalence of 1 in 2.000.000. It is caused by pathogenic variants in ACVR1 gene and characterized by soft tissue heterotopic ossification, starting in the second decade of life. It is associated to early mortality caused by respiratory complications. It evolves in flare-ups, triggered by soft tissue injuries; therapy is symptomatic, using analgesia, steroids and diphosphonates. We report a 12-year-old female with left renal agenesis, hallux valgus and intellectual disability, presenting with a six months history of thoracic kyphosis, tender nodules in the thorax, and rigidity of right elbow and left knee. Clinical examination revealed dysmorphic facial features. A magnetic resonance showed heterotopic ossification nodules, which was confirmed with spinal radiography. These findings prompted the diagnosis of FOP. Pain treatment was started, and prednisone was used during flare-ups. The ACVR1 gene was analyzed and a pathogenic variant, p. Arg206His, was found, confirming the diagnosis of FOP.

The aim of the present study was to investigate the effect of ultrasound-guided bilateral posterior quadratus lumborum block (QLB) and lateral QLB on postoperative pain scores after laparoscopic cholecystectomy.

The accomplishment of successful pain treatment requires evaluation, characterization and quantification. The present study characterized pain and survival in a cohort of patients with cancer with bone metastasis who were treated with intravenous bisphosphonates. A total of 84 patients self-completed the Brief Pain Inventory (BPI) and 36-Item Short Form Survey (SF-36), between November 2010 and March 2011 with a 5-year survival follow-up as a surrogate marker of cancer burden. The median age was 62 years old (34-85), 64% of patients were female and 58% of these females had breast cancer. In the population, self-reported pain was 91.6%, with 29 patients (34.5%) reporting severe pain (score 7-10). Among these patients, only 13 (44.8%) presented a similar report to that of their clinical files and 5 were undergoing treatment with strong opioids (17.2%). A total of 45 patients (46%) had not been prescribed analgesic drugs, of these patients, 32 were treated with a weak opioid, and 13 with a strong opioid. An association was observed between pain records and the prescribed analgesic (P=0.031). BPI maximum pain and overall survival data were analyzed, and a significant association was identified between male patients presenting severe pain and decreased survival (P=0.004). Male survival was associated with severe pain, which is consistent with other data. The results revealed a skeletal-related events (SRE)-free survival (time elapsed from diagnosis of the first bone metastasis to the first SRE) of 9 months (4.39-13.73, 95% CI) with a statistically significant difference between subgroups of time since diagnosis of bone metastasis (P=0.005). The added value of the present study is the suggestion that complete and accurate pain narratives are mandatory and may contribute to the optimization of analgesia, and may help to increase survival rates. Optimal pain management for patients with cancer remains an urgent requirement.

Limited information is available regarding the characteristics of delaminated rotator cuff tears as compared with nondelaminated tears. Furthermore, there is conflicting information regarding the effects of delamination on the anatomic healing of repaired cuffs.

Chronic pilonidal disease is a common debilitating condition often seen in general practice. It is a cause of considerable morbidity and social embarrassment, but recent developments in treatment options provide promising solutions to this problem.  OBJECTIVE: This article recaps pilonidal sinus development and presentation, details methods of treatment in the primary care setting and explores new specialist management options available in Australia.

Sympathetic joint effusion (SJE) and sympathetic synovial effusion (SSE) are recognized as causes of noninflammatory effusion with <2000 white blood cell (WBC) WBC/mm in the joint and bursa, respectively. Data on normal range SJE/SSE with <200 WBC/mm are unknown. We aimed to investigate the incidence, disease characteristics, and associated triggers of normal range SJE/SSE and to propose diagnostic criteria.

Only a few studies have examined the effects of regular acetaminophen drip infusion as postoperative analgesia in lung cancer surgery.
