Objective: Burn injuries remain a large financial burden on the healthcare system. According to CDC statistics (2010), nonfatal and hospitalized burns in the U.S. cost $1.8 billion for an annual incidence of ∼486,000 cases. To date, no technique proves to be the ideal therapy of deep partial-thickness burns. In this study, we review a trial usage of ACell (ACell, Inc.) wound matrix on deep partial-thickness burns. Approach: Burn patients were admitted through the Vanderbilt Emergency Department. Three were consented to receive ACell therapy...

Chronic wounds are an increasingly prevalent disease with a significant healthcare burden. These wounds often do not respond to standard of care therapy alone, requiring the use of adjuvant therapies. Epidermal grafting, previously utilized primarily for correction of leukoderma, is increasingly being recognized as a beneficial therapy for wounds, both acute and chronic. Epidermal grafting has been shown to be effective in the management of chronic wounds, with successful healing in refractory patients. It has not only been shown to be effective, but it is also associated with lower cost and morbidity than traditional skin grafting techniques as well as improved donor site healing...

INTRODUCTION: Epidermal grafting has several advantages over full-thickness or split-thickness grafts in the treatment of complex non-healing wounds. These include the low risk of donor site complications, minimal patient discomfort, and abstention from the operating room. Traditionally, the lack of reliable epidermal harvesting techniques has limited its clinical utilization. The development of an automated suction blister epidermal graft (SBEG) harvesting device may facilitate clinical utilization of this technique...

Acute compartment syndrome (ACS) is a serious complication of lower-extremity trauma caused by accidents or post-procedure complications. ACS is characterized by increased pressure within the compartment, resulting in reduced blood flow, tissue hypoxia, and tissue necrosis. Fasciotomies to relieve pressure and debridement of necrotic tissue comprise primary treatment. My purpose is to present initial experience using negative pressure wound therapy with instillation and dwell time (NPWTi-d)* to treat fasciotomy wounds in two patients...

OBJECTIVE: Cardiovascular diseases (CVD) are common in patients with chronic obstructive pulmonary disease (COPD) and the BODE index is an important tool for the prognostic assessment of COPD patients. It is well known that epicardial fat thickness (EFT) is related to CVD. However, there are very few data about the relationship between EFT and BODE index. The aim of this study is to investigate the relationship between EFT and BODE index in patients with COPD. PATIENTS AND METHODS: We prospectively included 157 patients with COPD and 45 controls in the present study...

Flexible alternating current electroluminescent devices (ACEL) are more and more popular and widely used in liquid-crystal display back-lighting, large-scale architectural and decorative lighting due to their uniform light emission, low power consumption and high resolution. However, presently how to acquire high brightness under a certain voltage are confronted with challenges. Here, we demonstrate an electroluminescence (EL) enhancing strategy that tetrapod-like ZnO whiskers (T-ZnOw) are added into the bottom electrode of carbon nanotubes (CNTs) instead of phosphor layer in flexible ACEL devices emitting blue, green and orange lights, and the brightness is greatly enhanced due to the coupling between the T-ZnOw and ZnS phosphor dispersed in the flexible polydimethylsiloxane (PDMS) layer...

BACKGROUND: The ability to deconstruct plant biomass without conventional pretreatment has made members of the genus Caldicellulosiruptor the target of investigation for the consolidated processing of lignocellulosic biomass to biofuels and bioproducts. These Gram-positive bacteria are hyperthermophilic anaerobes and the most thermophilic cellulolytic organisms so far described. They use both C5 and C6 sugars simultaneously and have the ability to grow well on xylan, a major component of plant cell walls...

Vitiligo is a multifactorial acquired dermatosis characterised by achromic or hypochromic macules and by the absence of functioning melanocytes. Treatment depends on the extent of the affected areas and on disease activity. Surgical techniques have proven to be effective in stable cases but can be time-consuming and, in some cases, aesthetically unsatisfying or painful for the patients. The aim of the study was to assess the clinical safety and effectiveness of a new automatic epidermal skin harvesting device in patients with stable localised vitiligo over a minimum 12-month period...

Traditionally, the surgical approach to managing abdominal injuries was to assess the extent of trauma, repair any damage and close the abdomen in one definitive procedure rather than leave the abdomen open. With advances in medicine, damage control surgery using temporary abdominal closure methods is being used to manage the open abdomen (OA) when closure is not possible. Although OA management is often observed in traumatic injuries, the extension of damage control surgery concepts, in conjunction with OA, for the management of the septic patient requires that the general surgeon who is faced with these challenges has a comprehensive knowledge of this complex subject...

Although immediate postmastectomy breast reconstruction is favored over delayed reconstruction, it remains associated with high complication rates. Potential complications include seroma formation, dehiscence, infection, and tissue necrosis along incision edges. Closed incision negative pressure therapy (ciNPT; Prevena Incision Management System, KCI, an Acelity company, San Antonio, Tex.) has been reported to help hold incision edges together, protect incisions from external contamination, and remove fluid and infectious material...

Primary cardiac sarcomas are rare and carry a grave prognosis. Improved survival requires a complete margin negative resection of the tumor. These surgical resections are often large and complex, requiring extensive reconstructive procedures. The appropriate material for cardiac reconstruction is not known. We have used glutaraldehyde-fixed bovine pericardium in our early series but have recently employed the MatriStem(®) Surgical Matrix PSMX membrane (ACell(®), Inc.; Columbia, MD), a unique proprietary urinary bladder matrix derived from porcine urinary bladder with the potential for viability and tissue ingrowth...

UNLABELLED: Epidermal skin grafting presents an alternative to traditional autografts since only epidermal skin is harvested from the donor site. Split-thickness skin grafts are associated with difficulties at the donor site, including excessive pain, delayed healing, fluid loss, and unsatisfactory cosmetic results - all exacerbated in patients with comorbidities. A new automated epidermal harvesting tool (CelluTome Epidermal Harvesting System, KCI, an Acelity company, San Antonio, TX) involves concurrent application of heat and suction to normal skin to produce epidermal grafts...

BACKGROUND: Septal ulceration is a mucositis involving the mucous membranes of the nasal septum. Patients often complain of nasal irritation, crusting, and epistaxis. Presently, there is no gold standard for the treatment of septal ulcerations. Currently described therapies include local debridement, septal dermoplasty, septal flap reconstruction, and cadaveric dermal graft repair; however, no therapy has demonstrated a consistent improvement of symptoms. We present a novel approach for the treatment of chronic septal ulceration, using an extracellular matrix scaffold (MatriStem® Wound Care Matrix, ACell, Inc...

OBJECTIVE: Negative-pressure wound therapy (NPWT) is a mainstay in the treatment of acute and chronic wounds. Following the success of the Vacuum-Assisted Closure system (Kinetic Concepts Inc [KCI], an Acelity Company, San Antonio, Texas), many similar systems were developed with minor variations. However, these systems are best suited to wounds with soft-tissue defects. Moreover, the need for a canister to collect wound exudate adds to the size and weight of the device. A canister-free (CF) NPWT device was cleared by the FDA for the treatment of chronic wounds (Kalypto Medical, Mendota Heights, Minnesota)...
