Bilateral Fasciocutaneous V-Y Advancement Flaps for Reconstruction of a Stage IV Sacral Pressure Injury in a Burn Patient: A Case Report and Literature Review

International Journal of Medical Students
Background: Pressure injuries (PIs) in the sacral region are a major reconstructive challenge, particularly in critically ill patients or those with a history of extensive burns. Healing capacity is often impaired, and the availability of healthy tissue

Risks of Laparoscopic Harvest of Free Intestinal Flaps for Esophageal Reconstruction

, 2021
Background: Performing ablative surgery using an laparoscope is a common practice. However, its use in the harvest of a segment of intestine for reconstruction has 2 major challenges: risk of damage to the vascular pedicle of the flap as well as to the ...

Receptogenesis in a Vascularized Robotic Embodiment

Advanced Science, EarlyView.
Functional augmentation of situated robots via ex novo hardware generation extends physical adaptability. Drawing inspiration from open circulatory systems for mass and function redistribution, this study presents a vascularized robotic composite exhibiting receptogenesis ‐ the on‐demand construction of sensors ‐ from internal fluid reserves based on ...

Surgical Treatment of Relapsing Keloid of the Pinna by Fillet Flap

Actas Dermo-Sifiliográficas (English Edition), 2010
Keloid scars occur when, compared to normal healing, there is excessive formation of collagen after skin wounds or burns. Different treatments have been tried, though no particular one has been shown to be superior. The objective of this study was to assess the usefulness of the surgical technique originally described as keloid fillet flap in the ...

SemanticST: A Scalable Multi‐Contextual Graph Learning Framework for Uncovering Spatial Niches and Robust Multi‐Sample Integration in Spatial Transcriptomics

Advanced Science, EarlyView.
Technical limitations often let dominant signals overshadow rare cell types and fine‐grained heterogeneity in spatial transcriptomics. SemanticST, a graph neural network using multi‐semantic graph fusion and a novel min‐cut loss, recovers these subtle patterns.

Surgery for scar revision and reduction: from primary closure to flap surgery

Burns & Trauma, 2019
Scars are the final result of the four processes that constitute cutaneous wound healing, namely, coagulation, inflammation, proliferation, and remodeling. Permanent scars are produced if the wounds reach the reticular dermis.

Hyperbaric oxygen therapy accelerates vascularization in keratinized oral mucosal surgical flaps

, 2014
Background Hyperbaric oxygen therapy (HBOT) is thought to promote vascular regeneration in wounds. The purpose of this study was to investigate the role of HBOT in advancing vascular regeneration in healing oral mucosal surgical flaps. Methods A palatine

Discrete 2D Material Programming for 3D Shaping and Morphogenesis‐Inspired 4D Bioprinting

Advanced Science, EarlyView.
Cell‐compatible discrete 2D material programming enables 2‐to‐3D shape transformation and morphogenesis‐inspired 4D bioprinting. By patterning cell‐supportive microdomains within a responsive hydrogel, the approach programs in‐plane growth to encode target metrics.

A Magnetic‐Driven Self‐Rotation‐Stabilized Miniature Swimming Robot

Advanced Science, EarlyView.
Inspired by the stable rotational descent of seeds in nature, this study designs a magnetic‐driven self‐rotation‐stabilized miniature swimming robot (MSMSR). Based on a resonance‐driven strategy, the robot exhibits high swimming performance, offering enhanced directional swimming and improved resistance to water flow disturbances compared to existing ...
