Diabetic foot ulcer (DFU) is a common complication observed in diabetic patients and affects diabetic patients in multiple ways. Severe DFU even leads to amputation in many cases. Early detection and intervention of DFU in diabetic patients can significantly relieve the pain caused by the ulcer and also keep patients from losing limbs in severe cases. In this study, the risks of diabetic patients getting DFU were estimated through a hospital-based survey. This survey collected information from hospitalized diabetic patients in Wuhan City, Hubei Province, China, using a questionnaire...

Buruli ulcer (BU) is a chronic necrotizing disease of the skin and subcutaneous fat tissue. The causative agent, Mycobacterium ulcerans, produces mycolactone, a macrolide toxin, which causes apoptosis of mammalian cells. Only a small proportion of individuals exposed to M. ulcerans develop clinical disease, as surrounding macrophages may control the infection by bacterial killing at an early stage, while mycolactone concentration is still low. Otherwise, bacterial multiplication leads to in higher concentrations of mycolactone, with formation of necrotizing lesions that are no more accessible to immune cells...

OBJECTIVE: Because melanoma patients are at high risk of further disease, we aimed to study their melanoma prevention behaviours. METHODS: In a large cohort of patients newly diagnosed with high-risk melanoma in Queensland, Australia, we assessed clustering of preventive behaviours using latent class analysis. We assessed associated factors with prevalence proportion ratios (PPRs) and 95% confidence intervals (CIs) estimated by Poisson regression, and also if preventive behaviour was associated with better tumour prognosis at diagnosis...

Langerhans cell histiocytosis (LCH) is a rare disease characterized by a proliferation of cells that show immunophenotypic and ultrastructural similarities with antigen-presenting Langerhans cells of mucosal sites and skin. LCH in adults is rare, and there are still many undiagnosed/misdiagnosed patients. We describe LCH involvement of the perianal region of a 33-year-old male with a previous history of diabetes insipidus. The differential diagnosis and all the reported cases of LCH of the perianal skin involvement since its description in 1984 till 2016 are discussed...

Hereditary sensory neuropathy type 1 (HSAN1) may be the first genetic neuropathy amenable to a specific mechanism-based treatment, as L-serine supplementation can be used to lower the neurotoxic levels of 1-deoxysphingolipids (1-deoxySL) that cause the neurodegeneration. The treatment is so far untested in HSAN1C caused by variants in the serine palmitoyl transferase subunit 2 (SPTLC2) gene. The aim of this study was to establish whether oral L-serine lowers 1-deoxySL in a patient with HSAN1C, to perform a dose escalation to find the minimal effective dose, and to assess the safety profile and global metabolic effects of the treatment...

Multilineage differentiating stress enduring (Muse) cells, discovered in the spring of 2010 at Tohoku University in Sendai, Japan, were quickly recognized by scientists as a possible source of pluripotent cells naturally present within mesenchymal tissues. Muse cells normally exist in a quiescent state, singularly activated by severe cellular stress in vitro and in vivo. Muse cells have the capacity for self-renewal while maintaining pluripotent cell characteristics indicated by the expression of pluripotent stem cell markers...

Leukemia inhibitory factor (LIF) is a member of IL-6 family, which serves as a potent chemoattractant for neutrophils as well as a potent angiostatic factor. LIF has been implicated in various autoimmune inflammatory diseases, but its role still remains elusive in systemic sclerosis (SSc). Therefore, we investigated the potential role of LIF in the development of SSc by evaluating the clinical correlation of serum LIF levels, the expression of LIF and its receptors in skin samples, and in vitro experiments with human dermal microvascular endothelial cells...

 Behçet's disease is a chronic, recurrent, inflammatory disorder characterized by orogenital ulcers and skin lesions; serious manifestations also include ocular, large vessel, gastrointestinal and neurological involvement. Genetic and unknown environmental factors modify the wide clinical spectrum of the disease. During the long clinical course of the disease, testicular and epididymal involvement has been reported, with scrotal pain and swelling being the most common symptoms. In this review, we discuss the various aspects of epididymo-orchitis in Behcet's disease patients, and we evaluate the diagnostic approaches as well as the empirical therapeutic modalities of this entity...

A 73-year-old female was admitted to our hospital with abdominal pain and diarrhea. Computed tomography detected distension of the small intestine. A palmar erythema, multiple oral ulcers, and desquamation of the fingers appeared after hospitalization. Small-bowel endoscopic images showed multiple ulcers. We attributed this case to infection with Yersinia pseudotuberculosis based on the changes in Y. pseudotuberculosis antibody titers throughout the course of the illness. This report is valuable, as it illustrates the endoscopic characteristics of a Y...

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...

Pyoderma gangrenosum is an inflammatory, ulcerative, neutrophilic dermatosis that is clinically characterized by rapidly evolving, painful, necrotic skin lesions. It is typically associated with chronic systemic inflammatory or neoplastic diseases, but may also occur secondary to cutaneous injury or surgery (pathergy). Post-surgical pyoderma gangrenosum typically develops around surgical sites within the immediate postoperative period, mimicking early wound infection. However, common treatment strategies including antibiotics and debridement fail to improve or even worsen symptoms...

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...

Dermatofibrosarcoma protuberans with fibrosarcomatous differentiation (DFSP-FS) is a rare soft tissue tumor with more aggressive behavior and it is not clear what causes this type of skin cancer. We describe the case of a 48-year-old woman who was born with a vascular malformation in the sternal region and presented suddenly with a soft tissue sarcoma (DFSP-FS) in the same territory. She was initially treated by embolization as the sarcoma was misdiagnosed but the tumor within 6 months seemed to be growing rapidly and reached a giant dimension with ulceration and required surgical intervention...
