Frederick Li, Joseph Tice, Brian D Musselman, Adam B Hall
Improvised explosive devices (IEDs) are often used by terrorists and criminals to create public panic and destruction, necessitating rapid investigative information. However, backlogs in many forensic laboratories resulting in part from time-consuming GC-MS and LC-MS techniques prevent prompt analytical information. Direct analysis in real time - mass spectrometry (DART-MS) is a promising analytical technique that can address this challenge in the forensic science community by permitting rapid trace analysis of energetic materials...

PURPOSE: The open abdomen has become a standard technique in the management of critically ill patients undergoing surgery for severe intra-abdominal conditions. Negative pressure and mesh-mediated fascial traction are commonly used and achieve low fistula rates and high fascial closure rates. In this study, long-term results of a standardised treatment approach are presented. METHODS: Fifty-five patients who underwent OA management for different indications at our institution from 2006 to 2013 were enrolled...

INTRODUCATION: Negative pressure wound therapy (NPWT) represents an alternative method to optimize conditions for wound healing. Delayed wound closure is a significant health problem, which is directly associated with pain and suffering from patient's aspect, as well with social and financial burden. PRESENTATION OF CASE: We report a case of vacuum-assisted wound therapy with hypertonic solution distillation and continuous negative pressure application, in an infected wound after laparotomy for incisional hernia reconstruction with mesh placement...

BACKGROUND: Sandwich ventral hernia repair (SVHR) may reduce ventral hernia recurrence rates, although with an increased risk of surgical site occurrences (SSOs) and surgical site infections (SSIs). Previously, we found that a modified negative pressure wound therapy (hybrid vacuum-assisted closure [HVAC]) system reduced SSOs and SSIs after ventral hernia repair. We aimed to describe our outcomes after SVHR paired with HVAC closure. METHODS: We conducted a 4-y retrospective review of all complex SVHRs (biologic mesh underlay and synthetic mesh overlay) with HVAC closure performed at our institution by a single surgeon...

INTRODUCTION: The optimal treatment concept for temporary abdominal closure (TAC) in critically ill visceral surgery patients with open abdomen (OA) continues to be unclear. The VACM (vacuum-assisted closure and mesh-mediated fascial traction) therapy seems to permit higher delayed primary fascial closure rates (FCR) than other TAC procedures. MATERIAL AND METHODS: Patients of our clinic (n=58) who were treated by application of a VAC/VACM treatment manual in the period from 2005 to 2008 were retrospectively analysed...

BACKGROUND: Open abdomen treatment (OAT) is a significant burden for patients and is associated with considerable mortality. The primary aim of this study was to report survival and cause of mortality after OAT. Secondary aims were to evaluate length of stay (LOS) in intensive care unit (ICU) and in hospital, time to abdominal closure and major complications. METHODS: Retrospective review of prospectively registered patients undergoing OAT between October 2006 and June 2014 at Trondheim University Hospital, Norway...

INTRODUCTION: The "open abdomen" expression widely used to define a full-thickness defect of the abdominal wall intentionally made in some situations like abdominal compartment syndrome, has been replaced by a newest one called "laparostomy". The definitive closure of an open abdomen with a giant full abdominal thickness defect remains a problem. CASE REPORT: We present a 67-year old male with a descompressive laparostomy treated with a greater omentum flap sutured hermetically with interrupted stitches at the edges of the muscle wall, reinforced with large mesh of polypropylene (PP) placed on-lay and sutured to the fascia by two concentric running sutures of polypropylene...

BACKGROUND: The open abdomen technique may be used in critically ill patients to manage abdominal injury, reduce the septic complications, and prevent the abdominal compartment syndrome. Many different techniques have been proposed and multiple studies have been conducted, but the best method of temporary abdominal closure has not been determined yet. Recently, new randomized and nonrandomized controlled trials have been published on this topic. We aimed to perform an up-to-date systematic review on the management of open abdomen, including the most recent published randomized and nonrandomized controlled trials, to compare negative pressure wound therapy (NPWT) with no NPWT and define if one technique has better outcomes than the other with regard to primary fascial closure, postoperative 30-day mortality and morbidity, enteroatmospheric fistulae, abdominal abscess, bleeding, and length of stay...

Continuum solvation modeling based upon the Poisson-Boltzmann equation (PBE) is widely used in structural and functional analysis of biomolecules. In this work, we propose a charge-central interpretation of the full nonlinear PBE electrostatic interactions. The validity of the charge-central view or simply charge view, as formulated as a vacuum Poisson equation with effective charges, was first demonstrated by reproducing both electrostatic potentials and energies from the original solvated full nonlinear PBE...

BACKGROUND: Open abdomen is a salvage procedure that prevents catastrophes after severe intraabdominal traumas. However, following this life saving attempt, it is mostly not feasible to close the abdomen immediately after the recovery of intraabdominal injuries. Consequently, a staged reconstruction is required, and the first stage is usually a temporary closing approach. At the end of this stage, resulting giant "ventral hernia" is a burden for both the patient and the surgeon. Therefore a permanent repair is subsequently needed...

A new structure of flexible transparent electrodes is reported, featuring a metal mesh fully embedded and mechanically anchored in a flexible substrate, and a cost-effective solution-based fabrication strategy for this new transparent electrode. The embedded nature of the metal-mesh electrodes provides a series of advantages, including surface smoothness that is crucial for device fabrication, mechanical stability under high bending stress, strong adhesion to the substrate with excellent flexibility, and favorable resistance against moisture, oxygen, and chemicals...

The authors present the case of a 54-year-old man with ulcers on the dorsal hand and forearm with exposed extensor tendons after he received misdiagnoses at 2 other hospitals, leading to deep soft tissue defects from multiple debridements. Due to the complicated nature of the wound, the ulcers did not heal under the systemic medication. After careful debridement, the defect was primarily closed with a collagen-glycosaminoglycan biodegradable matrix (Integra Matrix Wound Dressing, Integra LifeSciences, Plainsboro, NJ) on the dorsal hand and covered with a mesh graft 14 days later...

Electrospun non-woven poly(ε-caprolactone) (PCL) microfiber meshes are described as biodegradable, mechanically robust, and reusable polymeric oil sorbents capable of selectively retrieving oil from simulated oil spills in both fresh and seawater scenarios. Hydrophobic PCL meshes have >99.5% (oil over water) oil selectivity and oil absorption capacities of ~10 grams of oil per gram of sorbent material, which is shown to be a volumetrically driven process. Both the oil selectivity and absorption capacity remained constant over several oil absorption and vacuum assisted retrieval cycles when removing crude oil or mechanical pump oil from deionized water or simulated seawater mixtures...

OBJECTIVE: Negative pressure wound therapy (NPWT) is a widely accepted treatment modality for open or infected wounds. Premature ending of NPWT occasionally occurs due to negative effects on the quality of life (QoL), however, the actual impact on QoL is unknown. The aim of this review is to analyse the effect of NPWT versus standard wound care (SWC) on QoL when used for the treatment of open or infected wounds. METHOD: A systematic literature search in a range of databases (PubMed, CINAHL, Medline, Web of Science, Science Direct Freedom Collection, SwetsWise, PSYCArticles and Infrotrac Custom Journals) using the following search terms; 'standard wound care', 'wound dressing', 'dressing', 'treatment', OR 'negative pressure wound therapy [MESH]', OR 'vacuum assisted closure' AND 'quality of life [MESH]', 'patient-satisfaction', OR 'experiences' was performed...

Erysipelas are common soft tissue infections responding to first-line antibiosis. Because of factors of related to responsible bacteria and host, complications can occur that need extensive surgery in addition to intensified drug therapy. We report on a 65-year-old woman with leg ulcer who developed an absceding and necrotizing panniculitis of the affected leg complicating erysipelas. Escherichia coli and Pseudomonas aeruginosa were identified. Debridement and surgical removal of inflamed subcutaneous adipose tissue was decisive to interrupt the process...
