Article Abstract
Background: There are no data comparing the use of self-gripping mesh with standard mesh in total extraperitoneal repair (TEP). In this prospective study we aim to study the incidence of chronic pain between Progrip (PG) and standard mesh fixed by fibrin sealant (FS).
Materials And Methods: Under Institutional Review Board approval, from April 2016 to May 2017, patients with primary unilateral or bilateral inguinal hernia eligible for TEP were recruited. Before mesh insertion they were randomized into PG or FS (Tisseel). Demographics, intraoperative, and postoperative data were recorded. Patients were followed up for at least 1 year. Visual Analog Scale was used to record pain scores. Primary outcome was the incidence of chronic pain at 3 months after surgery.
Results: One hundred fifty patients were randomized. Of the 150 patients (193 hernias), 76 were randomized to PG and 74 randomized to FS. Demographic data such as age, presence of comorbidities, smoking history, mean body mass index was comparable in both groups. Bilateral hernias occurred in 25 (32.9%) and 18 (24.3%) patients in PG and FS group, respectively. Mean mesh deployment time was 283.7 seconds (range, 140 to 720 s) in PG group and 301.9 seconds (range, 67 to 1006 s) in FS group (P=0.30). A total of 5 patients were lost at follow-up and they were excluded from subsequent data analysis. Seroma occurred in 15 (20.3%) and 16 (22.5%) patients in PG and FS group, respectively (P=0.45). Mean Visual Analog Scale at 2 weeks (cough) was highest at 1.05 and 1.02 in PG and FS group, respectively (P=0.62). Eight (12.3%) and 15 (23.4%) patients in PG and FG group, respectively, reported pain at 3-month follow-up (P=0.1). Of those who experienced pain, majority was mild pain which did not affect activities of daily living. At a mean follow-up of 13.1±5.4 months, no recurrence was detected.
Conclusions: There was no significant difference in terms of chronic pain between PG and FS group. The use of PG is effective in TEP.

MS4A4A belongs to the MS4A tetraspan protein superfamily and is selectively expressed by the monocyte-macrophage lineage. In this study, we aimed to evaluate the role of MS4A4A+ macrophages in rheumatoid arthritis (RA) pathogenesis and response to treatment. RNA sequencing and immunohistochemistry of synovial samples from either early treatment-naïve or active chronic RA patients showed that MS4A4A expression positively correlated with synovial inflammation.

Anal fissure causes pain and bleeding during or after bowel movements, significantly impacting individuals' quality of life. Current treatments aim to interrupt this cycle but have associated risks and limitations. The emergence of arginine, crucial for protein creation and nitric oxide (NO) production, presents an intriguing therapeutic avenue by the impact on reducing anal sphincter pressure and enhancing anoderm blood flow, due to its roles in vasodilation, anti-inflammatory responses, and collagen synthesis, which can promote wound healing and highlighting its potential as an alternative therapy.

Purpose: Primary ventral hernia repair is a common elective procedure; however, mesh placement practices vary widely, and there is limited evidence to guide optimal placement. This international study examined surgeons' preferences and considerations regarding mesh placement in elective primary ventral hernia repair.
Methods: We conducted an international cross-sectional survey targeting surgeons experienced in primary ventral hernia repair.

Background: The Type D personality ("distressed personality") is characterized by a combination of negative affectivity and social inhibition. While this personality style was originally researched in the context of cardiovascular disease, recent studies also show a significant association with chronic pain disorders, especially back pain.
Objectives: This narrative review examines the current state of knowledge on the relationship between type D personality and back pain.
