In this article we briefly review the biology, testing and interpretation of POLE and mismatch repair defects in EC.
  Total knee replacement (TKR) normally provides improvements of physical function and reduces pain. However, ∼20% of the patients report chronic postoperative knee pain. The aims of the present study were to assess the pain, physical function, and physiological characteristics 5 years after TKR surgery.
 
  Eighty patients were recruited 5 years after TKR and divided into 2 groups based on their average 24-hour knee pain intensity assessed on a visual analog scale (VAS 0 to 10) ("high pain group" VAS≥3; "low pain group" VAS<3). The patients completed the PainDETECT Questionnaire (PDQ), Oxford Knee Score (OKS), Pain Catastrophizing Scale, and Forgotten Joint Score-12. Furthermore, the patients underwent a clinical examination of the knees and high-sensitivity serum C-reactive protein was measured as an inflammatory marker.
 
  A total of 53% of the patients in the high pain group were not satisfied with the outcome, while only 11% of the patients in the low pain group was not satisfied, and the pain intensities in the 2 groups were 5.1 (4.6 to 5 to 6) and 1.1 (0.6 to 1.5) (P<0.001), respectively. Furthermore, the high pain group demonstrates worse scores in Forgotten Joint Score-12 (P=0.001), OKS function (P<0.001), OKS pain (P<0.001), and Pain Catastrophizing Scale (P<0.001).The high pain group demonstrated increased level of high-sensitivity serum C-reactive protein (4.3 mg/L [3.2 to 5.5] vs. 1.7 mg/L [1.2 to 2.2], P<0.001), and decreased range of motion in the knee (110 vs. 119-degree range of motion, P=0.013).
 
  Patients with high chronic postoperative knee pain 5 years after TKR demonstrate decreased physical function, higher levels of catastrophizing thoughts, and increased levels of inflammation.

  School-based educational programs have shown positive changes in health-related behaviors among adolescents. The aim of this study was to analyze the changes in pain-related knowledge among adolescents and in the use of positive responses to their peers' pain behaviors after watching a brief educational video.
 
  One hundred and thirty-five adolescents (mean age=13.27; SD=1.17) participated and provided demographic and pain-related information. They also responded to a pain-related knowledge questionnaire before (T1), after (T2), and 1 month after (T3) watching a brief pain educational video, and to a modified version of the Inventory of Parent/Caregiver Responses to the Children's Pain Experience at T1 and at T3.
 
  There was a significant increase in pain knowledge for all participants between T1 and T2 (η2p=0.73) and between T1 and T3 (η2p=0.62). An increase in responses considered to be positive to peers' pain behaviors (ie, the promotion of well-behaviors and coping responses) 1 month after watching the educational video was also found. Interestingly, these results were not associated with the chronic pain status of the participant.
 
  The findings showed that a brief and inexpensive educational video-based intervention in schools helps to increase pain-related knowledge and change responses to students with chronic pain. This has the potential to prevent chronic pain and related disability among students, and decrease bullying-like behaviors toward students with chronic pain.

  Postoperative pain after craniotomy is a significant clinical problem that is sometimes underestimated, although moderate or severe pain in early postoperative period complicates up to 60% of cases. The purpose of this prospective randomized multicenter trial was to determine the optimal timing for selective scalp block in patients undergoing general anesthesia for supratentorial craniotomy.
 
  After ethics committee approval and informed consent, 56 adult patients were enrolled, and randomly assigned to receive a selective scalp block combined with incision line infiltration preoperatively or postoperatively.
 
  Postoperative pain at 24 hours after the procedure was recorded in all 56 enrolled patients. In patients assigned to receive a scalp block preoperatively, median VAS score at 24 hours after surgery was 0 (0 to 2), and in patients assigned to receive a scalp block postoperatively it was 0 (0 to 3) (P>0.05). There was no difference in severity of pain at 24, 12, 6, and 2 hours after surgery between stoperative pain regardless of whether the scalp block is performed preoperatively (after general anesthesia induction) or postoperatively (before extubation). Patients assigned to receive a scalp block combined with incision line infiltration preoperatively needed less intraoperative opioids than those assigned to postoperative scalp block.Carbamazepine, an anticonvulsant drug, has shown antidepressant effects in clinical and experimental models. Nitric oxide (NO) is a neurotransmitter in the central nervous system and has been involved in a variety of diseases including depression.  https://www.selleckchem.com/erk.html  In the present study, the involvement of NO/cyclic GMP/KATP channels pathway in the antidepressant action of carbamazepine was investigated in mice. The antidepressant-like activity was assessed in the forced swim test (FST) behavioral paradigm. Carbamazepine reduced (40 mg/kg, intraperitoneal) immobility period. The antidepressant-like effect of carbamazepine (40 mg/kg, intraperitoneal) was prevented by pretreatment with L-arginine [substrate for NO synthase (NOS), 750 mg/kg, intraperitoneal], sildenafil (a PDE-5 inhibitor, 5 mg/kg, intraperitoneal) and diazoxide (K+ channels opener, 10 mg/kg). Pretreatment of mice with L-NAME (a non-selective NOS inhibitor, 10 mg/kg, intraperitoneal), methylene blue (direct inhibitor of both NOS and soluble guanylate cyclase, 10 mg/kg, intraperitoneal) and glibenclamide (an ATP-sensitive K+ channel blocker, 1 mg/kg, intraperitoneal) produced potentiation of the action of a sub-effective dose of carbamazepine (30 mg/kg, intraperitoneal).
