Minimizing acute postsurgical pain (APSP) remains a challenge, despite extensive research about it. This study comprehensively analyzed the literature on APSP to assess how the field has developed and where it may go in the future.

Palmar-plantar atopic dermatitis is a common and debilitating condition with significant diagnostic and management challenges.

Migraine is a worldwide disabling chronic brain disorder, some studies suggest acupuncture-related therapy plays an important role in raising efficiency rates and reducing migraine attacks. However, clinical trials comparing the efficacy of different interventions for migraine are limited and controversial. This network meta-analysis (NMA) was performed to review all randomized controlled trials (RCTs) comparing the effects of acupuncture-related therapy for migraine.

An overlap between the skin disease rosacea and the headache disease migraine has been established; however, the magnitude of this overlap and the distribution between subtypes/phenotypes remains unclear.

Orthodontic tooth movement (OTM) is a tissue remodeling process based on orthodontic force loading. Compressed periodontal tissues have a complicated aseptic inflammatory cascade, which are considered the initial factor of alveolar bone remodeling. Since skeletal and immune systems shared a wide variety of molecules, osteoimmunology has been generally accepted as an interdisciplinary field to investigate their interactions. Unsurprisingly, OTM is considered a good mirror of osteoimmunology since it involves immune reaction and bone remolding. In fact, besides bone remodeling, OTM involves cementum resorption, soft tissue remodeling, orthodontic pain, and relapse, all correlated with immune cells and/or immunologically active substance. The aim of this paper is to review the interaction of immune system with orthodontic tooth movement, which helps gain insights into mechanisms of OTM and search novel method to short treatment period and control complications.

Many patients with osteoarthritis experience pain which can lead to higher healthcare expenditures. It is important to understand the factors that drive the excess expenditures associated with pain in osteoarthritis.

Due to the rarity of the condition, Valentino's syndrome is an underrated differential diagnosis for acute appendicitis. We describe a patient with Valentino's syndrome in whom preoperative and intraoperative diagnoses were challenging due to misleading clinical, investigative, and morphological findings. A 31-year-old woman who was on methylprednisolone for sensory radiculopathy presented to the emergency department with acute right lower quadrant pain. The clinical diagnosis of acute appendicitis was supported by the elevated inflammatory markers and ultrasonographic findings. An appendicectomy and an ovarian cystectomy were performed due to the findings of mild appendicitis and right ovarian endometrioma, respectively. Postoperatively, she developed peritonitis with a purulent bile-stained discharge from the surgical site and per vagina. Contrast-enhanced computed tomography of the abdomen showed a retroperitoneal collection at the second lumbar vertebral level extending along the right paracolic gutter to the pelvis and intraperitoneal fluid collections in right lower quadrant and pelvis. An emergency exploratory laparotomy confirmed a perforation at the posterior aspect of the duodenum which was repaired with an omental patch. Unfortunately, relaparotomy and end ileostomy were required due to colonic perforation with the eroded drain tube. She made an uneventful recovery with intensive care and underwent ileostomy reversal after 12 weeks. We emphasize the clues to have a high degree of suspicion during preoperative and intraoperative evaluation to recognize this lethal mimicker of acute appendicitis.

Lower back pain (LBP) is the primary reason leading to dyskinesia in patients, which can be experienced by people of all ages. Increasing evidence have revealed that paraspinal muscle (PSM) degeneration (PSMD) is a causative contributor to LBP. Current research revealed that fatty infiltration, tissue fibrosis, and muscle atrophy are the characteristic pathological alterations of PSMD, and muscle atrophy is associated with abnormally elevated oxidative stress, reactive oxygen species (ROS) and inflammation. Interestingly, microgravity can induce PSMD and LBP. However, studies on the molecular mechanism of microgravity in the induction of PSMD are strongly limited. This study identified 23 differentially expressed genes (DEGs) in the PSM (longissimus dorsi) of mice which were flown aboard the Bion M1 biosatellite in microgravity by bioinformatics analysis. Then, we performed protein-protein interaction, Gene Ontology function, and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis for the DEGs. We found that Il6ra, Tnfaip2, Myo5a, Sesn1, Lcn2, Lrg1, and Pik3r1 were inflammatory genes; Fbox32, Cdkn1a, Sesn1, and Mafb were associated with muscle atrophy; Cdkn1a, Sesn1, Lcn2, and Net1 were associated with ROS; and Sesn1 and Net1 were linked to oxidative stress. Furthermore, Lcn2, Fbxo32, Cdkn1a, Pik3r1, Sesn1, Net1, Il6ra, Myo5a, Lrg1, and Pfkfb3 were remarkably upregulated, whereas Tnfaip2 and Mafb were remarkably downregulated in PSMD, suggesting that they might play a significant role in regulating the occurrence and development of PSMD. These findings provide theoretical basis and therapeutic targets for the treatment of PSMD.

Endometriosis is a disease defined by the presence of endometrial tissue in extrauterine locations. This chronic condition is frequently associated with pain and emotional disorders and has been related with altered immune function. However, the specific involvement of immune cells in pain and behavioral symptoms of endometriosis has not been yet elucidated. Here, we implement a mouse model of non-surgical endometriosis in which immunocompetent mice develop abdomino-pelvic hypersensitivity, cognitive deficits, anxiety and depressive-like behaviors. This behavioral phenotype correlates with expression of inflammatory markers in the brain, including the immune cell marker CD4. Depletion of CD4 + cells decreases the anxiety-like behavior of mice subjected to the endometriosis model, whereas abdomino-pelvic hypersensitivity, depressive-like behavior and cognitive deficits remain unaltered. The present data reveal the involvement of the immune response characterized by CD4 + white blood cells in the anxiety-like behavior induced by endometriosis in mice. This model, which recapitulates the symptoms of human endometriosis, may be a useful tool to study the immune mechanisms involved in pain and behavioral alterations associated to endometriosis.

Regional anesthesia is frequently employed in efforts to improve postoperative analgesia and reduce opioid requirements following abdominal surgery. The purpose of the current analysis was to determine if there was a difference in postoperative pain and opioid consumption between patients who underwent open total abdominal hysterectomy (TAH) and received ultrasound-guided bilateral transversus abdominis plane (TAP) blocks using either liposomal bupivacaine or ropivacaine. A single-center retrospective analysis was conducted of 215 patients from November 2018 through March 2020 who underwent an open TAH and received bilateral TAP blocks with either liposomal bupivacaine or ropivacaine. The primary outcome measure was opioid consumption at regular intervals until discharge, and the secondary outcome measures included pain scores, incidence of nausea/vomiting, and use of antiemetics at the same time intervals. Intraoperative opioid consumption and postanesthesia recovery unit opioid requirements were similar between the two groups. Opioid requirements at 24 hours ( < 0.04) and 48 hours ( < 0.01), as well as total morphine equivalent requirements ( < 0.05), were significantly lower in the liposomal bupivacaine group compared to the ropivacaine group. Patients undergoing open TAH who received liposomal bupivacaine TAP blocks required fewer postoperative opioids to achieve similar pain scores when compared to patients who received ropivacaine TAP blocks.
