Refinements in the design and division of the thenar flap to achieve better functional results.

ABSTRACT: Though the thenar flap has been described since 1926, its use has not been widespread. The main criticisms are donor site morbidity and proximal interphalangeal joint (PIPJ) stiffness. In this paper, we describe a standard design technique for flap design and division to address these two issues. From July 2018 to April 2019, a total of ten patients underwent thenar flap reconstruction of the fingertip. The flap dimensions ranged from 10 mm × 10 mm to 25 mm × 15 mm. All the flaps survived. One patient developed wound infection post division. All donor sites were closed primarily without skin graft. We are using mirror image technique to elevate the flap to ensure that it is inset in the position as we planned without displacement. It largely reduced the chance of rotation and extensive tension when fix the finger to the thenar region. Our technique allows for the flap design to be individually customized based on the orientation of the defect, making it simpler and more replicable. We have also emphasized how care during division of the thenar flap can help prevent complications.

Project description:Discovery of new pharmaceutical substances is currently boosted by the possibility of utilization of the Synthetically Accessible Virtual Inventory (SAVI) library, which includes about 283 million molecules, each annotated with a proposed synthetic one-step route from commercially available starting materials. The SAVI database is well-suited for ligand-based methods of virtual screening to select molecules for experimental testing. In this study, we compare the performance of three approaches for the analysis of structure-activity relationships that differ in their criteria for selecting of "active" and "inactive" compounds included in the training sets. PASS (Prediction of Activity Spectra for Substances), which is based on a modified Naïve Bayes algorithm, was applied since it had been shown to be robust and to provide good predictions of many biological activities based on just the structural formula of a compound even if the information in the training set is incomplete. We used different subsets of kinase inhibitors for this case study because many data are currently available on this important class of drug-like molecules. Based on the subsets of kinase inhibitors extracted from the ChEMBL 20 database we performed the PASS training, and then applied the model to ChEMBL 23 compounds not yet present in ChEMBL 20 to identify novel kinase inhibitors. As one may expect, the best prediction accuracy was obtained if only the experimentally confirmed active and inactive compounds for distinct kinases in the training procedure were used. However, for some kinases, reasonable results were obtained even if we used merged training sets, in which we designated as inactives the compounds not tested against the particular kinase. Thus, depending on the availability of data for a particular biological activity, one may choose the first or the second approach for creating ligand-based computational tools to achieve the best possible results in virtual screening.
