REVIEW
James P Reichmann, Phillip M Stevens, John Rheinstein, Christopher D Kreulen
Forty years of clinical experience and peer reviewed research studies support the use of non-weight bearing removable rigid dressings (RRD) as an effective means of post-operative management of transtibial amputations. We reviewed the published medical evidence regarding the use of RRDs as a postoperative management strategy, culminating in an evidence-based practice recommendation. Published peer reviewed literature on the topic was searched and classified by level of evidence based on the research design utilizing the scale recommended by the PM&R Journal (level I through V)...

INTRODUCTION: Rupture of the Achilles' tendon is a common injury occurring particularly in middle-aged men due to sports trauma. Operative treatment is preferred generally due to lower risk of re-rupture. Possible complications of the operation include suture granulomas. Suture granulomas might represent a foreign body reaction, which itself is the end-stage response of the inflammatory wound-healing process to biomaterials. It may occur with both absorbable and non-absorbable suture materials such as silk in our case...

Osteopontin (OPN) is known to be overexpressed in numerous carcinomas. Although abundant OPN has been reported to be correlated with poor survival in non-small cell lung cancer (NSCLC) but their clinical and prognostic significance in SCLC remains unknown. In this study, RNA-sequencing was used to obtain gene expression data in SCLC tissue samples and OPN expression levels were then investigated using qPCR, immunohistochemical and Western blot. We found OPN was one of the most upregulated genes. Besides, the correlation of OPN with tumor clinicopathological characteristics was evaluated and we found OPN was associated with advanced tumor stages...

Wound dressings based on bacterial cellulose (BC) can form a soft and conformable protective layer that can stimulate wound healing while preventing bacteria from entering the wound. Bacteria already present in the wound can, however, thrive in the moist environment created by the BC dressing which can aggravate the healing process. Possibilities to render the BC antimicrobial without affecting the beneficial structural and mechanical properties of the material would hence be highly attractive. Here we present methods for functionalization of BC with ε-Poly-L-Lysine (ε-PLL), a non-toxic biopolymer with broad-spectrum antimicrobial activity...

Diabetic foot ulcers (DFUs) often result in severely adverse outcomes, such as serious infections, hospitalization, and lower extremity amputations. In last few years, to improve the outcome of DFUs, clinicians and researchers put their attention on the application of low intensity pulsating electro-magnetic fields through Therapeutic Magnetic Resonance (TMR®). In our study, patients with DFUs have been divided into two groups: The Sham Group treated with non-functioning TMR® device, and the Active Group treated with a functioning device...

Enterococcus faecalis is one of most frequently isolated bacterial species in wounds yet little is known about its pathogenic mechanisms in this setting. Here, we used a mouse wound excisional model to characterize the infection dynamics of E. faecalis and show that infected wounds result in two different states depending on the initial inoculum. Low dose inocula were associated with short term, low titer colonization whereas high dose inocula were associated with acute bacterial replication and long term persistence...

MicroRNA (miR)-124 has been implicated in malignant melanoma (MM). However, the detailed regulatory mechanism of miR-124 in the malignant phenotypes of MM cells has remained largely elusive. A total of 68 pairs of MM tissues and adjacent tissues were collected. Reverse-transcription quantitative polymerase chain reaction was used to examine the mRNA expression of versican as well as the expression of miR-124, and the protein expression of versican was assessed by western blot analysis. MTT, wound healing and Transwell assays were used to determine cell proliferation, migration and invasion, respectively...

Hepatocellular carcinoma (HCC) is one of the most prevalent cancers worldwide and the second most common cause of cancer-related mortalities. With a high potential for metastasis and recurrence, HCC is refractory to cure. The present study aimed to explore the role of a recent-discovered LncRNA, AB209630, in human HCC, in order to provide new insights useful for clinical HCC diagnosis and treatment. Reverse transcription-quantitative polymerase chain reaction was performed to examine the expression of AB209630 in clinical HCC samples and the adjacent non-cancerous tissues...

PURPOSE: Triple-negative breast cancer (TNBC) is an especially aggressive and hard-to-treat disease. Although the anticancer role of kaempferol has been reported in breast cancer, the effect of kaempferol on TNBC remains unclear. MATERIALS AND METHODS: This experiment investigated the migration-suppressive role of a low dose of kaempferol in TNBC cells. Wound-healing assays and cell invasion assays were used to confirm the migration and invasion of cells treated with kaempferol or transfected indicated constructs...

Formyl peptide receptor 2 (FPR2) has been identified as a member of the G protein-coupled chemoattractant receptor (GPCR) family and has been implicated as playing a role in both inflammation and cancer development. Epithelial ovarian cancer (EOC) has been suggested to be correlated with both infectious and non-infectious inflammation. To date, the role of FPR2 in EOC remains poorly understood and controversial. In the present study, we aimed to investigate the potential of FPR2 in regulating EOC. We performed immunohistochemistry and RT-qPCR to analyzed expression of FPR2 in EOC tissues and the correlation between FPR2 and EOC clinicopathological characteristics as well as prognosis were also analyzed...

The most favorable treatment for acute Achilles tendon ruptures remains controversial. In particular, three key questions are intensively debated: is operative or non-operative treatment superior? If surgery is performed, should open or minimally invasive percutaneous techniques be used? How should the follow-up treatment be carried out? The aim of this article is to answer these essential questions based on the currently available evidence. Non-operative treatment leads to a higher rate of re-ruptures and inferior functional results when compared to operative treatment...

Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used to reduce inflammation by suppressing cyclooxygenases (COXs). NSAID eye drops are frequently prescribed after ocular surgery to reduce inflammation and pain, but this treatment has clinically significant side effects, including corneal ulcer and perforation. The molecular mechanisms underlying these side effects remain unknown. Recently, the COX product 12(S)-hydroxyheptadeca-5Z,8E,10E-trienoic acid (12-HHT) was identified as an endogenous ligand for leukotriene B4 receptor 2 (BLT2), which is important in maintenance of epithelial homeostasis...

INTRODUCTION: Predictive in vitro testing of novel wound therapeutics requires adequate cell-based bio-assays. Such assays represent an integral part during preclinical development as pre-step before entering in vivo studies. Simple "scratch tests" based on defected skin cell monolayers exist, however these can solely be used for testing liquids, as cell monolayer destruction and excessive hydration limit their applicability for (semi-)solid systems like wound dressings. In this context, a cell-based wound healing assay is introduced for rapid and predictive testing of wound therapeutics independent of their physical state in a bio-relevant environment...

Long non-coding RNAs (lncRNAs) have multiple functions in gene regulation and during cellular processes. However, the functional roles of lncRNAs in colorectal cancer (CRC) have not yet been well understood. In our previous study, we demonstrated that sTLR4/MD-2 complex can inhibit CRC in vitro and in vivo by targeting LPS. Therefore, the aim of the present study is to investigate the expression of lncRNA H19 in CRC and to evaluate its effect on the inhibition of sTLR4/MD-2 complex. The expression of H19 is measured in 63 CRC tumor tissues and adjacent normal tissues by quantitative real-time PCR (qRT-PCR)...

This paper describes a randomized, controlled, parallel-group, single-center clinical trial designed to compare non surgical treatment methods of deep partial thickness skin burns of the hand. All patients were scanned with the Laser Doppler Imaging device to determine the depth of the burn wound. Viable keratinocytes sites were determined according to the established Perfusion Units (PU) measurement system. The trial enrolled 87 patients with hand burn wounds in the section of 260-600PU. Hand burn patients were divided into the following four groups: treated with hydrocolloid dressings; treated with mechanical debridement of monofilament polyester fibers pad and then applying silver sulfadiazine; treated with gauze dressings containing enzymatic collagenase preparation...

Mesenchymal stem cells (MSCs) have been developed for a number of indications due to their regenerative and anti-inflammatory phenotypes and their utility is enhanced by the fact that allogeneic transplant is feasible with this cell type. Animal studies and early human cases indicate this has the potential to be an exciting new therapy for treating chronic non-healing wounds such as diabetic ulcers, burns and cutaneous radiation burns. This review will focus on the use of MSCs to treat thermal and radiation burns...

The study of indeterminate-growing organisms such as teleost fish presents a unique opportunity for improving our understanding of central nervous tissue growth during adulthood. Integrating the existing experimental data associated with this process into a theoretical framework through mathematical or computational modeling provides further research avenues through sensitivity analysis and optimization. While this type of approach has been used extensively in investigations of tumor growth, wound healing, and bone regeneration, the development of nervous tissue has been rarely studied within a modeling framework...

BACKGROUND: Open reduction and internal fixation is the standard treatment for displaced ankle fractures. However, the presence of comorbidities such as diabetes mellitus and BMI is associated with poor bone quality, and these factors may predict the development of postoperative complications. The study aim was to assess the role of diabetes mellitus and BMI in wound healing in patients younger than 65 years who were surgically treated for malleoli fractures. METHODS: Ninety patients, aged from 18 to 65 years old, with surgically treated ankle fracture, were retrospectively enrolled...

The disease burden of failing skin repair and non-healing ulcers is extensive. There is an unmet need for new diagnostic approaches to better predict healing activity and wound infection. Uncontrolled and excessive protease activity, of endogenous or bacterial origin, has been described as a major contributor to wound healing impairments. Proteolytic peptide patterns could therefore correlate and "report" healing activity and infection. This work describes a proof of principle delineating a strategy by which peptides from a selected protein, human thrombin, are detected and attributed to proteolytic actions...
