BACKGROUND: Acetyl-triacylglycerols (acetyl-TAGs) are unusual triacylglycerol (TAG) molecules that contain an sn-3 acetate group. Compared to typical triacylglycerol molecules (here referred to as long chain TAGs; lcTAGs), acetyl-TAGs possess reduced viscosity and improved cold temperature properties, which may allow direct use as a drop-in diesel fuel. Their different chemical and physical properties also make acetyl-TAGs useful for other applications such as lubricants and plasticizers...

C J Lewis, A Al-Mousawi, A Jha, K P Allison
A multitude of household and occupational compounds have the potential to induce chemical burns to the eye and skin. Without prompt intervention, irreversible visual loss and disfigurement may prevail. Diphoterine(®) and Hexafluorine(®) are amphoteric and hypertonic chelating solutions used in the management of general chemical and hydrofluoric acid burns, respectively. They rapidly neutralise both acid and alkali agents without heat release and limit diffusion, making them superior to water irrigation alone...

BACKGROUND: Burns present a devastating injury to patients. Burns caused by chemical agents, present a worse scenario. In a resource limited country like Nigeria, readily available sources of these corrosive agents are mainly from lead-acid battery vendors and to some extent local small scale soap manufacturers who use caustic soda. We hypothesized that with the reduction in small scale soap manufacturing and increasing trend towards modernization in the use of dry cell batteries, chemical burns may be on the decline, and we sought to investigate this...

Covering tibial bone exposure from third degree burns to the lower limbs is a challenging task for the plastic surgeon. We present our experience of covering tibial exposure from burns in three different patients, where four limbs were involved and three muscular flaps were used in conjunction with one another; i.e. the tibialis anterior flap, the medial gastrocnemius flap and the hemisoleus flap. Through the use of this technique, tibial bone exposure, ranging from 15-30 cm, was successfully covered. This technique constitutes a good solution for surgically challenging wounds...

Anterior cervical contractures of the neck represent a great challenge for plastic and reconstructive surgeons. Necks can be reconstructed with a wide range of surgical techniques, including chimeric flaps, supercharged flap, pre-expanded flaps, "superthin" flaps and perforator flaps. The supraclavicular flap is easy to harvest without the need for free tissue transfer. It provides a relatively large flap for neck resurfacing with tissue very similar to that of the neck. Between January 2013 and March 2015, 20 patients suffering from postburn neck contracture underwent reconstruction with 20 unilateral supraclavicular artery perforator flaps...

Fungal infection is a leading cause of death in burns patients and incurs significant costs for burn units. Our aim was to determine epidemiology of these infections, and analyze risk factors in the burns intensive care unit of the National Center for Burns and Plastic Surgery at Ibn-Rochd University Hospital, Casablanca. It is a retrospective review of all patients admitted from 2011-2014 who developed cultures positive for fungal organisms. Criteria for nosocomial fungal infections were those of the Center for Disease Control in Atlanta (1988, revised 1992, 2004)...

Paul M Glat, Thomas Davenport
The reconstructive ladder is a term coined by reconstructive plastic surgeons to describe levels of increasingly complex management of wounds. The first rungs of the ladder is allowing the wound to heal by secondary intention, advancing up the ladder to direct tissue closure, with skin grafting and tissue transfer (flaps) comprising the higher rungs. Skin grafting and tissue transfer (flaps) at the middle and higher rungs of the ladder are often necessary for the treatment of complex burn injuries. Our purpose is to describe how dehydrated human amnion/chorion membrane allografts may be used as an adjunctive treatment...

INTRODUCTION: Social support and ego resiliency play a great role in maintaining the physical and mental health of patients with burn injuries. The present study has been designed to compare ego resiliency levels and the degree of social support in patients with a burn injury and their healthy counterparts. METHODS: This study was conducted in two teaching hospitals in Lahore, Pakistan from May 2015 to July 2015. A total of 80 burn patients presenting in outpatient departments of general surgery, plastic surgery, and burn centers of these hospitals were surveyed conveniently, and for comparison, 80 patients presenting in outpatient departments with minor ailments, for routine checkups or follow-ups were recruited...

Cell therapy with autologous or allogeneic keratinocytes applied as a single-cell suspension is well established in clinical practice in the treatment of severe burn injuries to augment epithelial barrier restoration. Yet, the application of cell sprays can lead to significant cell loss owing to lack of adhesion of cell suspension to the wound bed. The development of a robust and controllable method of transplanting cells onto the wound bed is yet to be established. The ability to control adhesion and distribution of cells by using a cell carrier embedded in a biodegradable scaffold could significantly improve the treatment of cutaneous wounds with keratinocyte cell therapy...

Background: The success of tissue transplantation and long-term tissue stability after wound healing depends on sufficient tissue perfusion. Laser Doppler-supported procedures allow for an objective measurement of relative tissue perfusion. The development of Speckle-based Laser Doppler imaging now enables a real-time representation of tissue perfusion. The perfusion of tissues relevant in plastic surgery such as scars, phalangeal replantations and burn wounds were systematically analysed by Laser Speckle Contrast Analysis (LASCA) imaging...

Thermal injuries are common and the majority will initially present to primary care physicians. Despite being a part of the objectives of training in family medicine (FM) and emergency medicine (EM), previous study has shown that in practice, gaps exist in the delivery of care. An electronic survey was sent to all FM/EM trainees at our university for the 2014 to 2015 academic year. Plastic Surgery trainees were included as a control group. Demographics and educational/clinical experience were assessed. Trainee comfort was measured on a five-point Likert scale across 15 domains related to thermal injuries...

PREMISE OF THE STUDY: Functional trait plasticity in resource capture traits has been suggested as an underlying mechanism promoting invasive species establishment and spread. Earlier studies on this mechanism treat invasiveness as a discrete characteristic (i.e., invasive vs. noninvasive) and do not consider the potential impacts of evolutionary history. In the present study, we used a continuous measure of invasiveness and a phylogenetic framework to quantify the relationship between functional trait expression, plasticity, and invasiveness in Rosa...
