Mussel-inspired adhesive antioxidant antibacterial hemostatic composite hydrogel wound dressing via photo-polymerization for infected skin wound healing.

Bioact Mater 2022 Feb 23;8:341-354. Epub 2021 Jun 23.

Frontier Institute of Science and Technology, and State Key Laboratory for Mechanical Behavior of Materials, and Key Laboratory of Shaanxi Province for Craniofacial Precision Medicine Research, College of Stomatology, Xi'an Jiaotong University, Xi'an, 710049, China.

With the increasing prevalence of drug-resistant bacterial infections and the slow healing of chronically infected wounds, the development of new antibacterial and accelerated wound healing dressings has become a serious challenge. In order to solve this problem, we developed photo-crosslinked multifunctional antibacterial adhesive anti-oxidant hemostatic hydrogel dressings based on polyethylene glycol monomethyl ether modified glycidyl methacrylate functionalized chitosan (CSG-PEG), methacrylamide dopamine (DMA) and zinc ion for disinfection of drug-resistant bacteria and promoting wound healing. The mechanical properties, rheological properties and morphology of hydrogels were characterized, and the biocompatibility of these hydrogels was studied through cell compatibility and blood compatibility tests.

Less-invasive Treatment for Group A Streptococcal Fasciitis with Rapid Antigen Detection Test and Collagen/Gelatin Sponge.

Plast Reconstr Surg Glob Open 2021 Sep 13;9(9):e3793. Epub 2021 Sep 13.

Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Kyoto University, Kyoto, Japan.

Patients with severe group A Streptococcus (GAS) induced necrotizing soft tissue infection sometimes develop Streptococcal toxic shock syndrome, which is a life-threatening condition with an extremely high fatality rate. Obtaining survival is the most important goal; however, an early diagnosis for debridement surgery and quick granulation formation for skin grafting surgery can better preserve the extremity functions. The patient was a 47-year-old man with a history of atopic dermatitis who presented with GAS-induced necrotizing soft tissue infection in his left lower extremity. Read More

Bioglass promotes wound healing by inhibiting endothelial cell pyroptosis through regulation of the connexin 43/reactive oxygen species (ROS) signaling pathway.

Lab Invest 2021 Sep 14. Epub 2021 Sep 14.

Institute of Life Sciences, Engineering Laboratory of Zhejiang province for pharmaceutical development of growth factors, Biomedical Collaborative Innovation Center of Wenzhou, Wenzhou University, Zhejiang, China.

Bioactive glass (BG) has recently shown great promise in soft tissue repair, especially in wound healing; however, the underlying mechanism remains unclear. Pyroptosis is a novel type of programmed cell death that is involved in various traumatic injury diseases. Here, we hypothesized that BG may promote wound healing through suppression of pyroptosis.

MRI of the Meniscus.

Clin Sports Med 2021 Oct;40(4):641-655

Musculoskeletal Radiology, Department of Radiology, DC069.10, University of Missouri, Columbia, MO, USA.

The menisci of the knee are accurately evaluated by MRI. Knowledge of normal anatomy, imaging parameters, imaging appearance of the normal and torn meniscus, and common anatomic variants and pitfalls are essential in obtaining the correct imaging diagnosis. There are multiple imaging signs of meniscal tear, including linear signal intensity extending to an articular surface on at least 2 images, altered meniscal shape, displaced meniscal flap, ghost meniscus, meniscal extrusion, and parameniscal cyst.

Fluorodeoxyglucose Positron-Emission Tomography/Computed Tomography and Magnetic Resonance Imaging for Adverse Local Tissue Reactions near Metal Implants after Total Hip Arthroplasty: A Preliminary Report.

Clin Orthop Surg 2021 Sep 17;13(3):320-328. Epub 2021 Aug 17.

Department of Orthopedic Surgery, Faculty of Medicine, Oita University, Yufu, Japan.

Background: Plain computed tomography (CT) and magnetic resonance imaging (MRI) are useful for diagnosing adverse local tissue reactions after metal-on-metal total hip arthroplasty (THA), but metal artifacts can hamper radiological assessments near the implants. We sought to clarify the usefulness of 18F-fluorodeoxyglucose positron-emission tomography (18F-FDG-PET) CT and MRI in the periprosthetic region, which is difficult to assess after THA due to metal artifacts.

Methods: We performed preoperative 18F-FDG-PET/CT and 18F-FDG-PET/MRI, as well as plain CT and MRI, in 11 metal-on-metal THA patients who underwent revision surgery. Read More

Clin Exp Dermatol 2021 Sep 4. Epub 2021 Sep 4.

Department of dermatology, Saudi German hospitals and clinics, Opposite of American School, Hessa Street 331 West, Al Barsha 3, Exit 36 Sheikh Zayed Road, Dubai, United Arab Emirates.

Keloids are aberrant tissue scarring typically occurring in the injured skin, caused by the overgrowth of granulation tissue or collagen type III during the healing process. Keloid has a genetic component, and therefore, it can be genetically transmitted. Keloids are difficult to treat because of their post-excisional recurrence and impact the quality of life due to psychological stress on cosmetic concerns and functional disability. Read More

Endosc Int Open 2021 Sep 16;9(9):E1371-E1380. Epub 2021 Aug 16.

Division of Gastroenterology and Hepatology, University of Toledo, Toledo, Ohio, United States.

Esophageal defects (leaks, fistulas, and perforations) are associated with significant morbidity and mortality. Endoluminal vacuum-assisted closure (EVAC) is a novel intervention that entails the use of sponges in the defect along with negative pressure to achieve granulation tissue formation and healing and has been gaining popularity. We performed a systematic review and pooled analysis of available literature to assess the safety and effectiveness of EVAC for esophageal defects. Read More

Predicting hyperbaric oxygen therapy success using the decision tree approach.

Ann Med Surg (Lond) 2021 Sep 16;69:102725. Epub 2021 Aug 16.

Department of Surgery, Faculty of Medicine, Hasanuddin University, Makassar, Indonesia.

Introduction: Hyperbaric oxygen therapy (HBOT), a procedure that involves the patient inhaling 100% oxygen gas under pressure, is currently used as an adjunctive treatment option for certain inflammatory conditions. HBOT can improve wound healing by increasing the rate of angiogenesis in injured tissue by increasing levels of vascular endothelial growth factor (VEGF). VEGF causes re-epithelialization, the migration of endothelial cells, and the formation of granulation tissue, which are involved in the wound healing process. Read More
