The present paper investigates drugs and polymers intended for the impregnation of textile carriers intended for use as wound covers. Their suitability was evaluated on the basis of the evaluation of the antimicrobial efficacy of a combination of trimetoprim and sulfadimidine with the local anaesthetics carbizocaine and lidocaine, and the immunomodulating substance fungal glucan. A greater inhibitory effect on the growth of microorganisms was shown by a combination of antimicrobial substances with carbizocaine. In the study of liberation of chlorohexidine from hydrophilic macromolecular dispersions its bond to glucan was confirmed. Dispersions of Natrosol proved to be more advantageous; chlorohexidine as well as local anaesthetics were released from them more rapidly than from methylcellulose gels. The dispersions under study are of a non-Newton character with pseudoplastic flow, glucan-containing gels are thixotropic.

With the widespread use of lidocaine for pain control in cancer therapy, its antitumor activity has attracted considerable attention in recent years. This paper provides a simple strategy of combining lidocaine with chemotherapy drugs for cancer therapy, aiming to relieve chemotherapy-induced pain and achieve stronger antitumor efficacy. However, there is still a lack of substantial pre-clinical evidence for the efficacy and related mechanisms of such combinations, obstructing their potential clinical application.

Introduction And Importance: Intraosseous anesthesia (IOA), an important technique in dental anesthesia, delivers anesthetic directly into the bone, enhancing patient comfort and minimizing side effects. Despite advantages, several disadvantages are known such as injection discomfort, root damage, mechanical obstructions and needle fractures. This report highlights a rare yet significant complication of focal mandibular osteonecrosis following IOA.
