Objective: The aim of this study was to calculate the volume of graft necessary for rehabilitation using varying lengths of implants, and to evaluate the usefulness of the planning dental software in determining the pre-operative volume of bone graft in maxillary sinus floor lifts.
Material And Methods: Using the CompuDent program, we calculated the volume of graft necessary for 62 sinus lifts. This volume was measured to raise the floor of each sinus to 13.4 and 15 mm in height.
Results: The average volume of graft to achieve a lift of 13.4 mm was 2.61 ± 0.69 cm³ for the right maxillary sinus, with the range of 1.38-4.1 cm³, and 2.68 ± 0.81 cm³ for the left maxillary sinus, with the range of 1.1-4.25 cm³. The average volume of graft to achieve a lift of 15 mm was 3.13 ± 0.75 cm³ for the right maxillary sinus, with the range of 1.59-4.81 cm³, and 3.29 ± 1.02 cm³ for the left maxillary sinus, with the range of 1.48-5.11 cm³. The statistical results showed a significant inversely proportional correlation between the average of the heights and the volume of graft in the right sinus.
Conclusions: The planning dental software is an effective tool in determining the volume of bone graft given the tool's simplicity, rapidness and possibility of standardization in all pre-surgical procedures.

A simple, fast, sample-saving, and sensitive liquid chromatography-tandem mass spectrometry method was established with a linear range adjusted by in-source collision-induced dissociation. Notably, this could simultaneously determine busulfan, fludarabine, phenytoin, and posaconazole in plasma from children, each having unique physical and chemical properties. The procedure necessitated only 20 μL of plasma and involved a simple protein precipitation process.

Background: Hepatocellular carcinoma (HCC) associated with major vasculature tumor extension is considered an advanced stage of disease to which palliative radiotherapy or chemotherapy is proposed. Surgical resection associated with chemotherapy or chemoembolization could be an opportunity to improve overall survival and recurrence-free survival in selected cases in a high-volume hepatobiliary center. Moreover, it has been 25 years since Couinaud described the entity of a posterior liver located behind an axial plane crossing the portal bifurcation.

Finger amputations following complex hand injuries (CHI) pose a significant challenge in hand surgery due to severe tissue trauma and neurovascular damage, necessitating precise arterial repair. While restoring arterial perfusion is critical, it remains unclear whether reconstructing both proper palmar digital arteries is required for optimal outcomes. This study evaluates whether restoring one or both arteries in finger replantation after complex injuries impacts perfusion and overall outcomes.

Introduction: To analyze the impact of Kirsten-Rat-Sarcoma Virus (KRAS) mutations on tumor-growth as estimated by tumor-doubling-time (TDT) among solid-dominant clinical-stage I lung adenocarcinoma. Moreover, to evaluate the prognostic role of KRAS mutations, TDT and their combination in completely-resected pathologic-stage I adenocarcinomas.
Methods: In this single-center retrospective analysis, completely resected clinical-stage I adenocarcinomas presenting as solid-dominant nodules (consolidation-to-tumor ratio > 0.
