Epidermolysis bullosa (EB), often referred to as the butterfly disease, is a group of rare genetic conditions characterized by skin that is delicate and fragile as butterfly wings. The skin blisters in response to friction, minor injury, or trauma. In certain types of EB, other organs, such as the esophagus, can also be affected, and secondary complications may require multiple interventions. While there has been significant progress in classifying the disease – identifying genes and proteins involved – there have been few advances in the treatment of the disease. The care of the EB patient focuses on management of symptoms, protecting the skin, and preventing complications. In this case report, the use of a multivalent wound-healing ointment (Terrasil®) was evaluated in a 60-year-old patient with a history of junctional EB. A polymerase chain reaction-based culturing was utilized to quantitatively test for bacteria and fungi at baseline and follow-up visits. Pain assessment and wound area were also documented at each visit. Following the application of the wound care ointment, there was a reduction in wound surface area on central (96%) and distal mid-back (92%) by treatment visit three, and there was a 96% reduction on the left shoulder blade ulcer by treatment visit four. Moreover, there was a noticeable drop in the percentage of bacteria detected by polymerase chain reaction. The wound care ointment was also effective in eliminating the fungal species and reducing pain, itching, blistering, and cracking around the wound … read more

The Neuropathic Diabetic Foot Ulcer Microbiome Is Associated With Clinical Factors
Nonhealing diabetic foot ulcers (DFUs) are a common and costly complication of diabetes. Microbial burden, or “bioburden,” is believed to underlie delayed healing, although little is known of those clinical factors that may influence microbial load, diversity, and/or pathogenicity. We profiled the microbiomes of neuropathic nonischemic DFUs without clinical evidence of infection in 52 individuals using high-throughput sequencing of the bacterial 16S ribosomal RNA gene. Comparatively, wound cultures, the standard diagnostic in the clinic, vastly underrepresent microbial load, microbial diversity, and the presence of potential pathogens. DFU microbiomes were heterogeneous, even in our tightly restricted study population, but partitioned into three clusters distinguished primarily by dominant bacteria and diversity. Ulcer depth was associated with ulcer cluster, positively correlated with abundance of anaerobic bacteria, and negatively correlated with abundance of Staphylococcus. Ulcer duration was positively correlated with bacterial diversity, species richness, and relative abundance of Proteobacteria, but was negatively correlated with relative abundance of Staphylococcus. Finally, poor glycemic control was associated with ulcer cluster, with poorest median glycemic control concentrating to Staphylococcus-rich and Streptococcus-rich ulcer clusters. Analyses of microbial community membership and structure may provide the most useful metrics in prospective studies to delineate problematic bioburden from benign colonization that can then be used to drive clinical treatment … read more
Reducing infection in chronic leg ulcers with an activated carbon cloth dressing
Chronic wounds are likely to have an increased bioburden, which in turn increases the risk of local infection. Indeed, infection is one of the most frequent complications of non-healing wounds, resulting in longer treatment times, increased risk of morbidity, greater resource use (of both dressings and nurse time) and, most importantly, a high personal cost to patients and their families (Cooper et al, 2014). While the ultimate aim is to treat the underlying wound, use of antimicrobial dressings is the cornerstone of the treatment of infected wounds. Most antimicrobial dressings work by killing the bacteria, and are indicated for use only when there are clear signs of increased bioburden and/or clinical signs of infections. As such, their use is assessed after 2 weeks, at which point it is advised that the clinician switches to another type of dressing if the wound is observed to be healing (Cooper et al, 2014) … read more
