INTRODUCTION: The use of cyanoacrylate glue as sealant on the exit site of peripherally inserted central catheters (PICCs) may offer some important clinical advantages. However, concerns exist about the potential interaction between cyanoacrylate and the material of the catheter itself. The aim of this study was to investigate the possibility of damage to the catheter secondary to a long-term contact with a two-component skin glue (N-butyl + octyl cyanoacrylate). METHODS: Twelve PICCs of different brands and types were selected (11 made of polyurethane and one made of silicon)...

INTRODUCTION: The aim of this study was to evaluate the effectiveness and safety of a new three-component 'bundle' for insertion and management of centrally inserted central catheters (CICCs), designed to minimize catheter-related bloodstream infections (CRBSIs) in critically ill children. METHODS: Our 'bundle' has three components: insertion, management, and education. Insertion and management recommendations include: skin antisepsis with 2% chlorhexidine; maximal barrier precautions; ultrasound-guided venipuncture; tunneling of the catheter when a long indwelling time is expected; glue on the exit site; sutureless securement; use of transparent dressing; chlorhexidine sponge dressing on the 7th day; neutral displacement needle-free connectors...

Silks are naturally occurring polymers that have been used clinically as sutures for hundreds of years. It's so for obtained from insects or worms, silk consists of a filament core protein, termed fibroin, and a glue-like coating made up of sericin proteins. An important component of silk has an extended history of being discarded as a waste in the course of silk processing. The cost of sericin for tissue engineering is underestimated and its capability in using as regenerative remedy has simply began to be explored...

We report a case of free flap deterioration which may have been induced by pressure gradient resulting from cranial defect overlying a ventriculoperitoneal shunt (VP shunt). The patient, male and aged 78, had a VP shunt operation for progressive hydrocephalus. Afterwards, the scalp skin flap surrounding the VP shunt collapsed and showed signs of necrosis, exposing part of the shunt catheter. After covering the defect with a radial forearm free flap, the free flap site showed signs of gradual sinking while the vascularity of the flap remained unimpaired...

INTRODUCTION: Rhinophyma is a rare, benign and unsightly disease of the skin of the nose that was first described a very long time ago, as illustrated by portrait of an old man with a bulbous nose holding his grandson, by Ghirlandaio in 1490. It was described for the first time by Ferdinando Hebra Von (1816-1880), as the third stage of rosacea. The objective of this study is to report the author's experience and propose a new treatment option in the management of rhinophyma. MATERIAL AND METHODS: We describe our experience of rhinophyma based on a retrospective case study...

PURPOSE: Penile adhesions are the most common complication after circumcision, although strategies to decrease them are poorly studied. We conducted a prospective, randomized trial comparing the use of 2-octyl cyanoacrylate (glue) skin adhesive to hydrophobic ointment after circumcision. METHODS: Patients <7years old undergoing circumcision were randomized to glue around the sutures and corona of the penis or antibiotic ointment. The primary outcome variable was postoperative penile adhesions...

Orbital arteriovenous malformations (AVMs) are rare vascular lesions that may be managed with endovascular embolization followed by surgical resection. Embolization is often accomplished with n-butyl-2-cyanoacrylate (nBCA), which is considered to be a safe and effective liquid occlusive agent. Localized vascular inflammation has been associated with endovascular nBCA use in histopathologic studies, but reports of systemic hypersensitivity reactions following endovascular embolization with nBCA are rare. We present a case of a 26-year-old male who developed an intermittent systemic urticarial reaction without cardiopulmonary compromise beginning four weeks after nBCA embolization of an orbital AVM...

The ability to monitor micropipette injections with a high-resolution fluorescent microscope has utility for a variety of applications. Herein, different approaches were tested for creating broad-band fluorescently labelled glass micropipettes including: UV cured glass glues, baked glass enamel containing fluorescent dyes as well as nanodiamonds attached during pipette formation in the microforge. The most robust and simplest approach was to use labelled baked enamel on the exterior of the pipette. This approach was tested using pipettes designed to mimic a mosquito proboscis for the injection of the malaria parasite, Plasmodium spp...

Lipoxin A4 (LXA4) is involved in the resolution of inflammation and wound healing; however, it is extremely unstable. Thus, to preserve its biological activities and confer stability, we encapsulated LXA4 in poly-lactic-co-glycolic acid (PLGA) microparticles (LXA4-MS) and assessed its application in treating dorsal rat skin lesions. Ulcers were sealed with fibrin adhesive and treated with either LXA4-MS, unloaded microparticles (Un-MS), soluble LXA4, or PBS/glue (vehicle). All groups were compared at 0, 2, 7, and 14 days post-lesions...

Salamanders have developed a wide variety of antipredator mechanisms, including tail autotomy, colour patterns, and noxious skin secretions. As an addition to these tactics, the red-legged salamander (Plethodon shermani) uses adhesive secretions as part of its defensive strategy. The high bonding strength, the fast-curing nature, and the composition of the biobased materials makes salamander adhesives interesting for practical applications in the medical sector. To understand the adhesive secretions of P. shermani, its components were chemically analysed by energy dispersive X-ray spectroscopy (EDX), inductively coupled plasma mass spectrometry (ICP-MS), amino acid analysis, and spectroscopy (ATR-IR, Raman)...

Sutures penetrate tissues to close wounds. This process leads to inflammatory responses, prolongs healing time, and increases operation complexity. It becomes even worse when sutures are applied to stress-sensitive and fragile tissues. By bonding tissues via forming covalent bonds, some medical adhesives are not convenient to be used by surgeons and have side effects to the tissues. Here egg albumen adhesive (EAA) is reported with ultrahigh adhesive strength to bond various types of materials and can be easily used without any chemical and physical modifications...

Meek micrografting permits wide expansion of skin grafts in true ratios from 3:1 to 9:1, as well as the utilization of poor donor sites. The proprietary glue critical to successful skin transference is unavailable in the United States. While the technique is widely employed worldwide, alternative glues resulted in poor skin transfer and frustrated use in American burn centers. The authors present their protocol resulting in effective MEEK skin transfer using Mastisol® adhesive: "The Rule of Sevens." 1) Soak the corks in normal saline for 7 minutes...

Over the past few years, the development of novel adhesives for biological soft tissue adhesion has gained significant interest. Such adhesives should be non-toxic and biocompatible. In this study, we synthesized a novel solid adhesive using nanostructured hydroxyapatite (HAp) and evaluated its physical adhesion properties through in vitro testing with synthetic hydrogels and mouse soft tissues. The results revealed that HAp-nanoparticle dispersions and HAp-nanoparticle-assembled nanoporous plates showed efficient adhesion to hydrogels...
