Objectives: A single case study is reported of a child who underwent several surgical procedures as result of congenital grade III subglottic stenosis. The anterior aspect of the right vocal cord was damaged and underwent atrophy during one of these procedures. Now, an active 10-year-old, the patient has become increasingly aware of his vocal limitations on functional activities. Injection of hyaluronic acid into the vocal folds has been known to provide improved voice quality in adults although there are no known cases reported of this procedure in children.
Methods: This article reports voice outcomes after injection of hyaluronic acid into the Reinke's space in a single case study. Voice recordings were made before, after, and 1 month after injection. The voice recordings were subject to acoustic and perceptual analysis.
Results: Post and follow-up voice recordings demonstrate decreased jitter, shimmer, and harmonics-to-noise ratio. Perceptual evaluation indicates improved voice quality.
Conclusion: Injection of hyaluronic acid in children who require voice augmentation is possible and may contribute to increased vocal function and improved voice outcomes.

Stem cell implantation holds promise for enhancing bone repair, but risks of pathogen transmission and malignant cell transformation should not be ignored. Compared to stem cell implantation, recruitment of endogenous stem cells to injured sites is more critical for in situ bone regeneration. In this study, based on the acidic microenvironment of bone injury, an HG-AA-SDF-1α composite hydrogel with a dual-control intelligent switch function is developed by incorporating stromal cell-derived factor (SDF-1α), arginine carbon dots (Arg-CDs), and calcium ions (Ca) into the oxidized hyaluronic acid/gelatin methacryloyl (HG) hydrogel.

To survey how cells from different tissue types respond to various changes in ECM mechanics and composition, we measured physical characteristics (adherent area, shape, cell stiffness, and cell speed) of 25 cancer and 5 non-tumorigenic cell lines on 7 different substrate conditions. Our results indicate substantial heterogeneity in how cell mechanics changes within and across tissue types in response to mechanosensitive and chemosensitive changes in ECM.

Hydrogel-based patches have demonstrated their values in diabetic wounds repair, particularly those intelligent dressings with continuous repair promoting and monitoring capabilities. Here, we propose a type of dual physiological responsive structural color particles for wound repair. The particles are composed of a hyaluronic acid methacryloyl (HAMA)-sodium alginate (Alg) inverse opal scaffold, filled with oxidized dextran (ODex)/quaternized chitosan (QCS) hydrogel.

Hyaluronic acid fillers rarely cause potentially devastating occlusive adverse events that require immediate hyaluronidase salvage infiltrations. An exploratory photographic investigation probed whether topical heparin's anticlotting and anti-inflammatory properties could synergize with and enhance the effectiveness of hyaluronidase. Based on heparin pharmacodynamics, the authors explored the rationale for associating topical heparins with hyaluronidase in treating occlusive side effects following accidental intra-arterial hyaluronic acid injections.

Purpose: Gastrostomy is the commonly used enteral feeding technology. The clinical risks caused by tube dislodgement and peristomal site infection are the common complications before complete tract maturation after gastrostomy. However, there is currently no relevant research to promote gastrostomy wound treatment and tract maturation.
