Spinal anesthesia for knee arthroscopy is a well-documented and safe procedure. However, some complications and higher costs have been reported. Also, many orthopaedic surgeons are reluctant to use local anesthesia for fear of having to convert to general anesthesia due to inadequate pain control. The purpose of this study is to compare local with spinal anesthesia in two groups of patients submitted to knee arthroscopy. Sixty-five patients were divided in two groups; based on the anesthesia method used, and submitted to the same surgical routine and postoperative analgesia protocol. They were evaluated for analgesia, level of postoperative pain, and level of satisfaction with the type of anesthetic. The two groups did not present any significant differences in relation to perioperative analgesia and pain on the first postoperative day, neither was there any difference in relation to emotional state. However, there was a significant difference in terms of acceptance of the procedure; 100% said they would accept the procedure again in the local anesthesia group, compared with 60.5% in the spinal anesthesia group; also, 100% in the local anesthesia group said they felt encouraged by the type of anesthesia, compared with 67.7% in the spinal anesthesia group. We can conclude that local anesthesia is similar to spinal anesthesia in almost all the aspects investigated, except in terms of acceptance and patients' level of satisfaction with the procedure. Local anesthesia can be a good alternative to spinal anesthesia, especially in outpatient departments, or when patients have restrictions to traditional models of anesthesia.

Faster referral and surgical intervention for rhegmatogenous retinal detachment during COVID-19: a comparison of pre- and during-pandemic cases.
Sci Rep

Eye Research Center, Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran.
Article Synopsis
- The study investigated how the COVID-19 pandemic affected patients with rhegmatogenous retinal detachment (RRD) at Farabi Eye Hospital in Iran, comparing patients from before and during the pandemic.
- A total of 375 patients were analyzed, revealing that those referred during the pandemic had quicker referral and surgical wait times, but no significant changes in clinical characteristics or surgical outcomes.
- The use of general anesthesia increased during the pandemic period, prompting the need for further research into this trend.
A comparative evaluation of the effects of white noise, brown noise, and pink noise on dental anxiety of pediatric patients undergoing dental extraction treatment: A randomized control study.

Background: Audio-analgesia is one of the unexplored aspects of behavior management in pediatric dentistry, and recently, there have been many new inclusions in shades of noise that were previously just limited to white noise, like brown noise and pink noise.
Aim: The aim of the study was to evaluate and compare the effectiveness of white noise, brown noise, and pink noise on dental anxiety in pediatric patients undergoing primary tooth extraction.

Do transversus abdominis plane (TAP) blocks improve pain after laparoscopic bilateral inguinal hernia repairs beyond the recovery unit? A randomized control trial.

Department of Surgery, Icahn School of Medicine at Mount Sinai, One Gustave L. Levy Place, Box 1259, New York, NY, 10029, USA.
Purpose: While surgeons agree that perioperative field blocks should be performed for open inguinal hernia surgery, there lacks consensus in the minimally invasive context. Prior small-scale randomized trials study pain scores only up to 24 h postoperatively. Thus, we sought to investigate the analgesic benefits of a bupivacaine transversus abdominis plane (TAP) block in the first 4 postoperative days.

Aim: To create and explore a novel patient-perceived burden of disease (PPBoD) score in a large Australasian cohort, and correlate PPBoD scores with demographics, disease and treatment factors.
Assessing Caries Removal Efficacy and Pain Perception in Children, Using Smart Bur Versus Carbide Bur: A Randomized Clinical Study.

Department of Preventive Dental Sciences, College of Dentistry, Jazan University, Jazan, Saudi Arabia.
BACKGROUND Dental caries removal is conventionally done using carbide burs, but non-metallic polymer burs have recently been developed with the aim of being more selective and causing less pain. The objective of the study is to evaluate and compare the effectiveness of caries removal, time taken, and patient compliance during restorations using smart bur and carbide burs in pediatric patients. MATERIAL AND METHODS A clinical study was designed and conducted at the Pedodontics Outpatient Department, with a focus on 40 children between 6 and 12 years old, who were split into 2 groups consisting of 20 children each: group 1, using a carbide conventional rotary bur, and group 2, using a smart bur.
