Efficacy and safety of parenteral and local application of tramadol in mandibular third molar extraction: a qualitative systematic review of current evidence.

Purpose: To assess the efficacy and safety of perioperative parenteral administration or submucosal infiltration of tramadol for perioperative pain control on the basis of pain intensity or analgesics consumption and perioperative outcomes in mandibular third molar surgery.

Material-methods: An electronic database search was conducted up to 10 November 2022 to retrieve all randomized controlled trials (RCTs), assessing the analgesic efficacy of parenteral use of tramadol implemented as an adjunct to local anesthesia or intraoperative sedation/general anesthesia, in surgical extraction of mandibular third molars. Modified Jadad scale and Cochrane bias tool were used for the qualitative appraisal.

N-Glycosylation of the Ig Receptors Shapes the Antigen Reactivity in Chronic Lymphocytic Leukemia Subset #201.

Subset #201 is a clinically indolent subgroup of patients with chronic lymphocytic leukemia defined by the expression of stereotyped, mutated IGHV4-34/IGLV1-44 BCR Ig. Subset #201 is characterized by recurrent somatic hypermutations (SHMs) that frequently lead to the creation and/or disruption of N-glycosylation sites within the Ig H and L chain variable domains. To understand the relevance of this observation, using next-generation sequencing, we studied how SHM shapes the subclonal architecture of the BCR Ig repertoire in subset #201, particularly focusing on changes in N-glycosylation sites.

Higher-order immunoglobulin repertoire restrictions in CLL: the illustrative case of stereotyped subsets 2 and 169.

Chronic lymphocytic leukemia (CLL) major stereotyped subset 2 (IGHV3-21/IGLV3-21, ∼2.5% of all cases of CLL) is an aggressive disease variant, irrespective of the somatic hypermutation (SHM) status of the clonotypic IGHV gene. Minor stereotyped subset 169 (IGHV3-48/IGLV3-21, ∼0.
