Defining the Zone of Acute Peripheral Nerve Injury Using Fluorescence Lifetime Imaging in a Crush Injury Sheep Model.
J Hand Surg Am
January 2025
Hand and Upper Extremity Division of Plastic and Reconstructive Surgery, University of California Davis, Sacramento, CA.
Purpose: Current technologies to define the zone of acute peripheral nerve injury intraoperatively are limited by surgical experience, time, cumbersome electrodiagnostic equipment, and interpreter reliability. In this pilot study, we evaluated a real-time, label-free optical technique for intraoperative nerve injury imaging. We hypothesize that fluorescence lifetime imaging (FLIm) will detect a difference between the time-resolved fluorescence signatures for acute crush injuries versus uninjured segments of peripheral nerves in sheep.

Background: Vitiligo is a chronic autoimmune disease manifested by depigmented patches of skin devoid of melanocytes. Baricitinib, a JAK inhibitor selectively targeting JAK1/2, has shown preliminary efficacy for vitiligo. We aimed to assess the efficacy and tolerability of combination therapy with baricitinib and narrowband UV-B (NB-UVB) to treat active nonsegmental vitiligo (NSV).

December 2024
Consultant Dermatologist, Indore, Madhya Pradesh, India.
Background: Tacrolimus, a topical calcineurin inhibitor (TCI) with immunomodulatory effects, is considered a viable treatment option for vitiligo. A consensus building exercise was undertaken to determine the role and clinical utility of topical tacrolimus in the management of vitiligo using input from experts in the field of dermatology.
Methods: Seventeen experts collaborated to create consensus statements using a modified Delphi methodology.
The Impact of Corneal Oedema on UV Light Transmission: An Experimental Study in Porcine Eyes.
J Clin Med
November 2024
Department of Optics and Optometry and Vision Sciences, Faculty of Physics, Universitat de València, Dr. Moliner, 50, Burjassot, E-46100 Valencia, Spain.
Corneal oedema is known for changing the cornea's optical properties, particularly its ability to transmit ultraviolet (UV) light, which is crucial for visual clarity and eye health. This study explores how changes in corneal thickness in oedematous states affect UV light transmission. This study included 107 porcine eyes with artificially induced corneal oedema.

Methods: This was a cross-sectional observational comparative study including 45 consecutive patients with progressive keratoconus planned for CXL. Mi-OCT (RESCAN 700) was used to measure central corneal thickness (CCT) during four stages of CXL: before epithelial debridement, after debridement, after riboflavin instillation, and after ultraviolet irradiation.
