Effects of capsulorhexis size and position on post-surgical IOL alignment.

In cataract surgery, post-surgical stability of the intraocular lens plays a major role. This study aims to explore how the size and decentration of the capsulorhexis affect intraocular lens decentration and tilt by using numerical methods. Finite element models included zonules, ciliary body, capsular bag, and an IOL with two open-loop haptics were built.

Traditional postero-medial ankle approach for Bartonícek type III in Volkmann Fractures: Is it useful?

Introduction: There is evidence that the presence of a posterior malleolus fracture (PMF) worsens the prognosis of ankle fractures, making conservative treatment a poor choice. PMFs include a heterogeneous group of bone injury patterns that are sometimes associated to medial malleolus extensions, as well as fibula fractures or syndesmotic damage. This requires the surgeon to be well-versed in anatomy to choose the appropriate surgical approach.

Clinical Trial With a Depigmented, Polymerized Mite Mixture Extract at Maximum Concentrations.

Background: Efficacy of allergen immunotherapy is dose-dependent; however, high doses of allergen may imply a greater risk of adverse reactions.

Objective: To assess the safety and tolerability of subcutaneous immunotherapy (SCIT) with mixtures of mite allergen extracts, Dermatophagoides pteronyssinus/Blomia tropicalis (Dpt/Bt) and Dermatophagoides pteronyssinus/Lepidoglyphus destructor (Dpt/Ld) at maximum concentrations, in adult patients with allergic rhinitis or rhinoconjunctivitis, and controlled allergic asthma due to a clinically relevant sensitisation to these mites.

Methods: An open-label, noncontrolled, nonrandomised, phase IIb clinical trial was carried out in three hospitals in Spain between September 2014 and May 2018.

Training in Lumbar Pedicle Screw Instrumentation Using a 3D-Printed Model: From Validation to Transferability Onto a Cadaver Model.

Lumbar pedicle screw placement in spinal surgery is complex and prone to errors, with notable risks to patients. Standard training methods, such as mentorship in operating rooms, pose safety concerns, prompting the need for alternative training tools. This study aimed to validate and use a three-dimensional (3D)-printed simulation model for lumbar pedicle screw insertion training and assess its effectiveness compared with standard methods.
