Contemp Clin Dent 2022 Jan-Mar;13(1):61-68. Epub 2022 Mar 23.

Objective: The purpose of this prospective, randomized study was to evaluate and compare the anesthetic efficacy of 0.8 ml of 4% articaine and 1.6 ml of 2% lidocaine administered through buccal infiltration (submucosal) only in adult male and female patients with irreversible pulpitis of maxillary 1 molar.

Study Design: Two hundred patients with irreversible pulpitis of the maxillary first molar were divided into four study groups and received only buccal infiltration of either 0.8 ml of 4% articaine or 1.6 ml of 2% lidocaine. Endodontic access was begun 7 min after the solution deposition. The success was defined as "no pain (0 mm)" or "weak/mild pain (>0 mm and ≤54 mm)" during access opening, and during the first file insertion till working length.

Results: The compiled data of the number of failed cases were analyzed by two sample proportion test and of mean pain scores were analyzed by Student's unpaired -test. < 0.05 was taken as statistically significant. No significant difference was found in the number of failed cases on using 4% articaine and 2% lidocaine ( > 0.05). Moreover, no significant difference was found in the number of failed cases between the genders in Group I (4% articaine with 1:100,000 epinephrine) and also in Group II (2% lidocaine with 1:80,000 epinephrine). On comparing the mean pain scores of failed cases, it has been found that females experience more pain than males in Group I (not significant) and Group II (significant).

Conclusion: The efficacy of 4% articaine with 1:100,000 epinephrine has been found to be better than 2% lidocaine with 1:80,000 epinephrine, as only 0.8 ml of 4% articaine with 1:100,000 epinephrine was effectively used as compared to 1.6 ml of 2% lidocaine with 1:80,000 epinephrine. Furthermore, females experience more pain as compared to males.

Department of Neurointervention Radiology, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China.

Background: The Pipeline for Uncoilable or Failed Aneurysms (PUFS) trial primarily demonstrated the safety and efficacy of the implantation of multiple pipeline embolization devices (multi-PEDs) for large/giant intracranial aneurysms. However, no study has focused on when, why, or how to apply multi-PEDs.

Objective: The purpose of this study was to investigate the indications and strategies of using multi-PEDs for complex intracranial aneurysms. Read More

Facultad de Medicina, Universidad de los Andes, Bogotá, Colombia.

Background: Although chronic urticaria (CU) is a common, cause of medical consulting both in general practitioners and allergist specialists worldwide, there is little information about its behavior and management in Latin America. Currently, national and international guidelines recommend using Omalizumab for cases refractory to management with antihistamines. Despite advances in the knowledge of Omalizumab for the management of CU, although there are few studies in underdeveloped countries, there are many studies evaluating the impact of Omalizumab treatment.
