Abstract
Introduction Trauma to the extremities is a common major health problem that requires special attention because it can have a dangerous impact on both the viability of the limb and the patient's life. Hyperbaric oxygen therapy is an alternative therapy hypothesized to improve the prognosis in lower extremity trauma. Case presentation We present a series of 7 cases of lower extremity trauma treated with hyperbaric oxygen therapy: soft tissue loss, neglected chronic burn injury, high-voltage electrical burn, gas gangrene, crush injury, chemical burn, and excoriation with skin loss. Discussion Hyperbaric oxygen therapy involves giving 100% oxygen in a chamber at pressures above atmospheric pressure (2–3 atm absolute [ATA]). It can increase oxygen delivery to peripheral tissues with vascular compromise, cytogenic and vasogenic edema, and cellular hypoxia caused by limb trauma. Conclusion Hyperbaric oxygen therapy has many benefits in lower extremity trauma for wound recovery, preventing complications, and helping patients return to daily activities. Hyperbaric oxygen therapy is an alternative therapy believed to improve the prognosis in cases of lower extremity trauma. We present 7 cases: soft tissue loss, chronic burn, high-voltage burn, gangrene, crush, chemical burn, and excoriation. Hyperbaric oxygen therapy has benefits for wound recovery, preventing complications, and return to daily activities.

Abstract
Background This retrospective study aimed to investigate the epidemiology of burns to the hand, including the causes, demographic data, management, and outcome in a single center in Southwest China between 2012 and 2017. Material/Methods A retrospective study included 470 patients with hand burns who were treated at a single hospital in Southwest China between 2012 and 2017. Demographic, injury-related, and clinical data were obtained from the clinical electronic data collection system. Results In 470 patients, men were more commonly admitted to hospital with hand burns (73.62%). Children under 10 years (29.57%) were the main patient group. Hospital admissions occurred in the coldest months, from December to March (55.11%). In 60.21% of cases, hand burns occurred outside the workplace. Fire (40.42%), electricity (30.85%), and hot liquids (20.21%) were the main causes of hand burns. Data from 428 patients showed that burns with a larger total body surface area and deeper burns were associated with surgery and amputation. Burn depth was a risk factor for skin grafting, and lack of burn cooling before hospital admission increased the risk of amputation. Data from 117 patients with localized burns showed that full-thickness burns and lack of cooling before admission were associated with an increased hospital stay. Conclusions The findings suggest that in Southwest China, prevention programs for children aged 0–9 years, injuries occurring in winter and non-workplace sites, and fire burns were imperative.

Int J Biol Macromol 2017; 102:1174-1185.

Abstract
Polymer blending is a strategy commonly used to obtain hybrid materials possessing properties better than those of the individual constituents regarding their use in scaffolds for Tissue Engineering. In the present work, the scaffolds produced by electrospinning solutions of polymeric blends obtained using a polyester (polycaprolactone, PCL), a polysaccharide (chitosan, CS) and a protein (gelatin extracted from cold water fish skin, GEL), were investigated. Solutions conductivity, shear viscosity and surface tension were determined. GEL-containing scaffolds were crosslinked with vapour phase glutaraldehyde (GTA). The scaffolds were characterized physico-chemically regarding fibre morphology, porosity, water contact angle, mechanical properties, chemical bonds and fibre and dimensional stability upon immersion in water and cell culture medium. The scaffolds were further tested in vitro for cell adhesion, growth and morphology of human foetal fibroblasts (cell line HFFF2). Results show that the nanofibrous scaffolds are hydrophilic and display the typical porosity of non-woven fibre mats. The CS/PCL and CS/PCL/GEL scaffolds have the highest elastic modulus (48MPa). Dimensional stability is best for the CS/PCL/GEL scaffolds. FTIR spectra confirm the occurrence of cross-linking reactions of GTA with both GEL and CS. Cell adhesion ratio ranked from excellent (close to 100%) to satisfactory (around 50%) in the order PCL/GEL>CS/GEL>CS/PCL/GEL>CS/PCL. Cell populations show an extended lag phase in comparison with the controls but cell proliferation occurs on all scaffolds until confluence is reached. In conclusion, all scaffolds studied possess characteristics that enable them to be used in skin tissue engineering but the CS/PCL/GEL scaffolds have better physical properties whereas the PCL/GEL scaffolds support a higher cell adhesion.

Abstract
Postburn contractures are a common occurrence after severe burn injuries. It is important to understand the pathologic condition and anatomy of specific postburn deformities in order to provide comprehensive surgical care. Postburn contractures can result in a flexion contracture, boutonniere deformity, burn syndactyly, metacarpophalangeal extension contracture, wrist contracture, or claw hand. A patient evaluation is performed before proceeding to the operating room. Surgery sequences require proper incision design, release of the skin, and deeper contracted structures and coverage with an appropriate flap or graft. Postoperative splinting, scar care, and therapy are equally important for a successful outcome.

Abstract
Improvements in critical care and burn victim resuscitation have led to increased survival of burned patients. Initial resuscitation, early excision of burned tissues, prevention of burn wound sepsis, and wound coverage remain mainstays of care. Many burn wounds require complex reconstruction. This is particularly important in the hand. Coverage of tendons, ligaments, joints, vessels, nerves, and bones of the hand requires healthy vascularized tissue to maintain viability and function. Local flaps or regional flaps may be within the burn zone of injury. Refined microvascular free tissue transfer techniques offer free tissue transfer as a procedure that can be safely performed.

Wound healing after thermal injury is improved by fat and adipose-derived stem cell isografts. J Burn Care Res 2015; 36:70-6.

Abstract
Patients with severe burns suffer functional, structural, and esthetic complications. It is important to explore reconstructive options given that no ideal treatment exists. Transfer of adipose and adipose-derived stem cells (ASCs) has been shown to improve healing in various models. The authors hypothesize that use of fat isografts and/or ASCs will improve healing in a mouse model of burn injury. Twenty 6 to 8 week old C57BL/6 male mice received a 30% surface area partial-thickness scald burn. Adipose tissue and ASCs from inguinal fat pads were harvested from a second group of C57BL/6 mice. Burned mice received 500 μl subcutaneous injection at burn site of 1) processed adipose, 2) ASCs, 3) mixed adipose (adipose and ASCs), or 4) sham (saline) injection (n = 5/group) on the first day postinjury. Mice were followed by serial photography until being killed at days 5 and 14. Wounds were assessed for burn depth and healing by hematoxylin and eosin (H&E) and immunohistochemistry. All treated groups showed improved healing over controls defined by decreased wound depth, area, and apoptotic activity. After 5 days, mice receiving ASCs or mixed adipose displayed a non-significant improvement in vascularization. No significant changes in proliferation were noted at 5 days. Adipose isografts improve some early markers of healing postburn injury. The authors demonstrate that addition of these grafts improves specific structural markers of healing. This improvement may be because of an increase in early wound vascularity postgraft. Further studies are needed to optimize use of fat or ASC grafts in acute and reconstructive surgery.

Abstract
OBJECTIVE The aim of this systematic review was to discuss the comparison of split-thickness skin graft (STSG) and full-thickness skin graft (FTSG) use as the treatment for volar digital and palmar burns in children. METHODS We conducted PubMed and Cochrane Library searches using keywords "hand injuries", "contracture" and "skin transplantation". The search was limited to studies published from 1st January 1980 until 31st December 2013 and used English language. We selected the studies based on specific inclusion and exclusion criteria. We assessed the quality of the studies by using Newcastle-Ottawa Scale (NOS) for cohort studies. RESULTS We included eight articles in our systematic review. One of those studies is a prospective cohort study and the others are retrospective cohort studies. Based on combined range of motion (ROM) evaluation in three studies, STSG group yielded poorer functional outcomes than FTSG group. However, there is no study which can fairly show that FTSG was significantly superior to STSG to achieve good functional outcomes. CONCLUSION Currently, there is no strong, high-quality evidence to prove that FTSG is superior to STSG to cover pediatric palmar burns. Either FTSG or STSG can be utilized with consideration of several influential factors especially splinting and physiotherapy.
