Introduction: Surgical site infection (SSI) after lower extremity (LE) bypass surgery is associated with longer length of stay, higher hospital cost, increased morbidity, and even graft loss. Silver impregnated dressings have been used by other surgical subspecialties to decrease SSI with reported success. The National Surgical Quality Improvement Program (NSQIP) published a national expected rate of 7.

Objective: Chronic wounds are a common clinical problem that necessitate the exploration of novel regenerative therapies. We report a method to investigate the in vitro wound healing capacity of an innovative biomaterial, which is based on amniotic membrane-derived stem cells (AMSCs) embedded in an alginate hydrogel matrix. The aim of this study was to prepare an sodium alginate-based hydrogel, cross-linked calcium chloride (CaCl with the active ingredient AMSC (AMSC/Alg-H) and to evaluate its in vitro effectiveness for wound closure.

Department of Chemical Science & Engineering, School of Materials and Chemical Technology, Institute of Science Tokyo, 2-12-1 Ookayama, Meguro-ku, Tokyo, 152-8552, Japan.
Purpose: We aimed to develop a novel fluorescent surgical gauze dyed with indocyanine green (ICG) to guide surgeons to the target anatomical destination during surgery for real-time navigation and to prevent gauze remnants after surgery.
Methods: Surgical gauze was dyed with an aqueous solution of ICG (5.0 × 10 mol L for Steraze, 1.
Bagging an Extremity for Negative-Pressure Wound Therapy: A Case Report.

Krešimir Bulić, MD, PhD, is Professor, Department of Plastic, Reconstructive and Aesthetic Surgery, University Hospital Center Zagreb, Croatia, and Department of Surgery, University of Zagreb School of Medicine. Lucija Gatin, MD, is Resident, Department of Plastic, Reconstructive and Aesthetic Surgery, University Hospital Center Zagreb.
Negative-pressure wound therapy (NPWT) is used to promote wound closure or to prepare a wound for definite coverage. However, the anatomy of the hand makes it difficult to apply dressings that require an airtight seal. In this report, the authors describe the case of a patient with an extensive defect of his right hand and forearm who was treated with a free fibula osteocutaneous flap transfer.
