One hundred and forty-two arthroscopies under local anesthesia, using "high pressure" irrigation-suction technique were carried out in 137 patients. With this technique the duration of the examination was shortened, the endoscopic field of vision was enlarged (posterior horn of the menisci could be visualized in most patients), the manipulation of the scope inside the joint cavity was easier and safer. More patients could have been examined during one session. The arthroscopic accuracy verified at 51 operations, was 90.5%, which is an improvement on our previous experience with arthroscopy under general anesthesia, with tourniquet and the routine " drip" technique.

Aim: The objective of the present study is to assess and compare the effectiveness of two different anesthetic agents, namely, 4% articaine and 2% lignocaine, in the extraction of primary molar teeth in children.
Materials And Methods: The study included 25 children requiring bilateral extractions of primary molar, with extraction performed on one side with 4% articaine and the contralateral side extraction with 2% lignocaine at two separate appointments. The anesthetic efficacy was evaluated objectively by assessing pain and the child's behavior at baseline, during injection and during extraction using the sound, eye, and motor (SEM) scale objectively, and subjectively using the faces pain rating scale (FPS).

Depression and pain are common comorbidities in cancer patients, and ketamine, a dissociative anesthetic, has shown potential in managing both. This review summarizes current literature on ketamine and its enantiomer, esketamine, in managing depression and pain in the oncologic population. Studies indicate that sub-anesthetic doses of intravenous ketamine and esketamine can alleviate postoperative depressive symptoms in cancer patients with a tolerable safety profile.

Minimally invasive Ponto surgery (MIPS) enables the installation of percutaneous bone-anchored hearing implants (BAHIs) with a drill guide through a hole punch incision. Despite being well established for adults, there is a lack of studies in the literature regarding its use in pediatric patients. The aim of the present study was to investigate the hearing performance and soft-tissue outcomes of the use of MIPS under local anesthesia in children with unilateral craniofacial malformation (UCM).
