We experimentally studied a new technique for anastomosis of small arteries which involves the telescoping method and a surgical adhesive with the objective of examining its clinical potential. This technique was applied to the unilateral femoral arteries of 27 mongrel dogs. After division of the artery, the distal artery was incised longitudinally, and the proximal end was invaginated into the opened artery. One stay suture and the elastomeric adhesive PUP201 were placed in the anastomotic site. The bursting and tensile strength and the patency were examined, and a histopathological study was performed at various intervals up to 1 year after the operation. The bursting strength exceeded 500 mm Hg. The patency rate of the anastomosed arteries was 100%. The mean percentage of stenosis to diameter of the proximal normal lumen was 20% one year after operation. The luminal surface of the anastomosed line was healed smoothly, and thrombi between the telescoped arteries were replaced by elastofibrotic union. In conclusion, small arterial anastomosis using the telescoping method and an elastomeric adhesive is easy and safe and provides good patency.

Purpose: To evaluate the intermediate-term visual and safety outcomes of the small-incision second-generation implantable miniature telescope (SING IMT) in patients with late-stage age-related macular degeneration (AMD) at 6 months post-surgery.
Design: Retrospective cohort study.
Methods: Medical records of patients implanted with the SING IMT at two sites in Italy were reviewed.

Aims: Bone preservation is a requirement for long-term stability of dental prostheses, which is all the more important in the posterior mandible, given the particular challenges these areas pose to prosthetic treatment. The objective was to investigate the implications of different prostheses on the atrophy of posterior alveolar bone after tooth loss.
Materials And Methods: A total of 457 treatment cases were retrieved from the medical documentation and information network.
Impact of Lower Limb Lengthening with Telescopic Nails on Functionality and Quality of Life in Patients with Achondroplasia.

Introduction: The short stature characteristic of patients with achondroplasia can negatively affect health-related quality of life (HRQoL). Lower limb lengthening reusing telescopic intramedullary nails (TIMNs) offers an alternative to external fixators, with the potential to enhance functionality, self-esteem, and HRQoL, while reducing complication risks, which this study aims to evaluate.
Materials And Methods: This retrospective study included nine patients with achondroplasia who underwent parallel transverse lengthening of femurs and/or tibias reusing a TIMN between 2015 and 2022.
Purpose: Previous studies have shown that subtrochanteric femoral fractures treated with intramedullary nails might lead to varus-procurvatum malalignment. Similar results have been reported when using antegrade intramedullary lengthening nails (ILNs). The purpose of our study is to examine if antegrade telescoping intramedullary lengthening nails lead to varus-procurvatum malalignment of the proximal femur and what are possible predictors of that shift.

Objectives: The aim of the study was to evaluate anatomical and functional outcomes of the Smaller-Incision New Generation Implantable Miniature Telescope (SING IMT™) in patients with bilateral advanced age-related macular degeneration (AMD).
Methods: This non-comparative retrospective single-surgeon interventional case series included patients with bilateral late-stage AMD who underwent cataract surgery and SING IMT™ implantation at the Sant'Anna University Hospital, University of Ferrara, Italy. The main outcome measures included corrected distance (CDVA) and near visual acuity (CNVA), endothelial cell loss (ECL), and incidence of complications.
