#1
Christopher J Greene, Christopher Bibbo
Traditional transmetatarsal amputations are a reliable level of amputation. However, amputations at the Lisfranc level have met with limited success owing to improper biomechanics resulting from tendon imbalance, ultimately leading to foot deformity positions and an unstable soft tissue envelope with ensuing skin breakdown, infection, and below-the-knee amputation. We describe proper tendon rebalancing that results in improved biomechanics and a more reliable and stable amputation at the more proximal Lisfranc level...

BACKGROUND: Lymphedema is a condition of localized protein-rich swelling from damaged or malfunctioning lymphatics. Because the immune system is compromised, there is a high risk of infection. Infection in patients with lymphedema may present in a variety of ways. OBJECTIVE: The goals of this review were to standardize the terminology of skin breakdown in the context of lymphedema, synthesize the available information to create best practice recommendations in support of the American Lymphedema Framework Project update to its Best Practices document, and create recommendations for further research...

Prolonged mechanical loading can lead to the breakdown of skin and underlying tissues which can, in turn, develop into a pressure ulcer. The benefits of pressure relief and/or redistribution to minimise risk have been well documented. Manufacturers have developed alternating air pressure mattresses (APAMs) to provide periodic relief for individuals on prolonged bed-rest. The present study describes the development of a control system, termed Pneumatic Manager which can vary the signature of an APAM, namely its pressure amplitude, cell profile and cycle period...

BACKGROUND AND OBJECTIVE: Pressure ulcers (PU) are a significant problem facing the health system in the United States. Here, we present preliminary case studies demonstrating feasibility of Spatial Frequency Domain Imaging (SFDI) to assess skin status in high-risk populations and pre-existing wounds. SFDI is a wide-field non-contact optical imaging technology that uses structured light to obtain tissue optical properties and of tissue constituents. This study aims to determine the fit of SFDI for PU care and determine the next steps...

The reconstruction of large cranial and scalp defects is a surgical and esthetic challenge. Single autologous tissue transfer can be insufficient due to the defect size and the anatomic complexity of the recipient site. Alloplastic patient-specific preformed implants can be used to recover hard tissue defects of the neurocranium. Nevertheless, for long-term success adequate soft tissue support is required. In this brief clinical study, the authors describe calvarian reconstruction in a 33-year-old patient with wound healing disorder after an initial resection of ependymoma...

PURPOSE: The use of flaps in the two-stage repair of posterior hypospadias associated with severe chordee has been well established. Despite the almost certain guarantee of flap take, complications such as diverticuli are still relatively high. While different applications of the tubularized incised plate have been described, experience with the application of the technique to the two-stage flap repair is very limited. A previous local review of 15 cases performed at the present institution during the period 1998-2003, using the technique as described by Rekit, revealed fistulae and diverticulum rates of 20% and 27%, respectively...

OBJECTIVES/HYPOTHESIS: Tracheotomy is a common procedure. A reliable method of securing the tracheotomy tube is essential to minimize accidental decannulation. However, skin breakdown has been reported in ∼30% of patients. We sought to evaluate rates of skin-related complications and accidental decannulation with the use of Velcro ties compared to twill ties. STUDY DESIGN: A nonblinded, randomized controlled trial comparing Velcro versus twill ties in patients undergoing tracheotomy between July 1, 2014 and January 31, 2016...

Due to the high intensification of poultry production in recent years, white chicken breast striping is one of the most frequently seen myopathies. The aim of this research was to develop a spectrophotometry-based sensor to detect white striping physiopathy in chicken breast meat in whole chicken carcasses with skin. Experiments were carried out using normal and white striping breasts. In order to understand the mechanism involved in this physiopathy, the different tissues that conform each breast were analyzed...

Increased filaggrin expression was found to be correlated with severity scores in chronic spontaneous urticaria (CSU); however, the role of filaggrin breakdown products (FBPs) in CSU has not been studied. We collected stratum corneum (SC) specimens from the volar forearms of 10 CSU patients, 10 AD patients, and 10 healthy normal controls (NCs) and measured contents of FBPs (pyrrolidone carboxylic acid [PCA] and urocanic acid [UCA]) using UPLC-MS/MS, transepidermal water loss (TEWL) and epidermal pH. Compared to NCs, cis-UCA level was increased in CSU lesions (P < 0...

Tissue stem cells contribute to tissue regeneration and wound repair through cellular programs that can be hijacked by cancer cells. Here, we investigate such a phenomenon in skin, where during homeostasis, stem cells of the epidermis and hair follicle fuel their respective tissues. We find that breakdown of stem cell lineage confinement-granting privileges associated with both fates-is not only hallmark but also functional in cancer development. We show that lineage plasticity is critical in wound repair, where it operates transiently to redirect fates...

The technique of cryosurgery has been used to control local recurrence in a variety of benign and malignant bone tumors. Early studies revealed significant complication rates (25%) that included fracture, infection, and soft tissue injury. Our method of cryosurgery has yielded excellent tumor control with improved complication rates. The objective of this study is to determine the characteristics of postoperative complications after pouring liquid nitrogen into curettaged bone defects, and to review our current indications and surgical technique in bone tumor management...

BACKGROUND: Ten percent of patients with a deep-vein thrombosis (DVT) will develop a fatal pulmonary embolism (PE), often initially asymptomatic. The risks and benefits of pharmacological thromboprophylaxis are well documented in respect of total joint arthroplasty and hip fractures, but little is understood about the incidence of venous thromboembolism (VTE) or the potential risks and benefits of chemoprophylaxis in foot and ankle surgery. OBJECTIVE: To determine whether prophylactic chemoprophylaxis had any impact on the prevention of VTE in a cohort of foot and ankle surgical patients requiring the combination of below-knee cast immobilisation and non-weightbearing for ≥4 weeks...

Cyanoacrylate adhesives can make the placement of spreader grafts in open septorhinoplasty technically easier, but its use is off-label beneath the skin. There is a theoretical risk of toxicity from cyanoacrylate breakdown products, but this risk has not been thoroughly studied in rhinoplasty. The objective was to evaluate the effects of subcutaneous cyanoacrylate use during spreader graft placement in rhinoplasty in a retrospective review of open septorhinoplasties in which 2-octyl cyanoacrylate was used to aid placement of spreader grafts...

IMPORTANCE: Improvements in skin appearance resulting from treatment with fractionated picosecond-lasers have been noted, but optimizing the treatment efficacy depends on a thorough understanding of the specific skin response. The development of non-invasive laser imaging techniques in conjunction with laser therapy can potentially provide feedback for guidance and optimizing clinical outcome. OBJECTIVE: The purpose of this study was to demonstrate the capability of multiphoton microscopy (MPM), a high-resolution, label-free imaging technique, to characterize in vivo the skin response to a fractionated non-ablative picosecond-laser treatment...
