: Military trainees are at high risk for skin and soft-tissue infections (SSTIs). Although Staphylococcus aureus is associated with purulent SSTI, it is unclear to what degree this pathogen causes nonpurulent cellulitis. To inform effective prevention strategies and to provide novel insights into SSTI pathogenesis, we aimed to determine the etiology of SSTI in this population. We conducted a prospective observational study in US Army Infantry trainees with SSTI (cutaneous abscesses and cellulitis) from July 2012 through December 2014...

Nipple-sparing mastectomy (NSM) offers improved cosmesis for women undergoing mastectomy; however, there is increased risk for complications with this technique. We sought to determine if standard anatomic measurements could be used to predict complications of NSM. We performed a retrospective review of NSM for which anthropometric measurements of sternal notch to nipple distance, base width, and inframammary fold to nipple distance were available, and compared outcomes by anatomic measurements. We identified 102 cases of NSM with measurements available for study performed in 55 patients...

Atopic dermatitis (AD) is a complex, chronic inflammatory skin disorder affecting more than 10% of UK children and is a major cause of occupation-related disability. A subset of patients, particularly those with severe AD, are persistently colonised with Staphylococcus aureus (S. aureus) and exacerbation of disease is commonly associated with this bacterium by virtue of increased inflammation and allergic sensitisation, aggravated by skin barrier defects. Understanding the complex biology of S. aureus is an important factor when developing new drugs to combat infection...

BACKGROUND: Lichen planus is a mucocutaneous papulosquamous itchy disease with unknown etiology. A number of factors such as immune mechanisms, viral agents, and drugs have been implicated in pathogenesis of lichen planus. In recent years, several studies have indicated the role of viral agents in this disease, including human herpesvirus-7 (HHV-7). Studies have given contradictory results, which is why we decided to study the possible association between lichen planus with HHV-7. METHODS: In this case-control study, which was conducted on 60 cutaneous classic lichen planus samples as well as 60 healthy control skin samples after matching the two groups in terms of gender and age, tissue samples of patients and controls were studied by real time polymerase chain reaction to detect for HHV-7...

The Brazilian forests have one of the world's biggest biodiversities. Achyrocline satureioides (macela) and Acmella oleracea (jambu) are native species from Brazil with a huge therapeutic potential, with proved anti-inflammatory and anesthetic action, respectively. The jambu's crude extract after depigmentation with activated charcoal and macela's essential oil were incorporated in a film made with hydroxyethyl cellulose. Those films were evaluated by mechanical test using a texturometer and anti-inflammatory and anesthetic activities by in vivo tests: wound healing and antinociceptive...

Understanding the cost of burn treatment is very important for patients, their families, governmental authorities and insurance companies. It alleviates patient and familial stress, provides a framework for better use of resources, and facilitates better performance between burn centers. Hospital burn costs can provide a basis for authorities to budget for acute burn treatment, for further management of chronic complications, and for planning prevention and public educational programs in Iran. To identify costs we used data from our burn registry program...

Mucor fungus infection is a rare opportunistic infection, rapidly progressive and often fatal in immunocompromised patients, or in patients with chronic debilitating diseases. We report six cases of trauma patients with mucormycosis. Three had severe thermal burns, one of them with a medical history of diabetes mellitus. The other three patients suffered from severe soft tissue injuries caused by traffic accidents. In all cases there had been spontaneous exposure and contact of the wounds with soil. During hospitalization, fungi cultures and/or biopsies of all wounds were performed and all resulted positive...

A 71-year-old man presented with a high fever, polyarthralgia, petechiae and palpable purpura accompanied by livedoid change on his legs and feet. Histopathological findings of the purpura revealed perivascular infiltration of neutrophils, mononuclear cells, and nuclear debris, and extravasation of red cells mainly in the upper dermis: all signs consistent with leukocytoclastic vasculitis. Small vessel thrombi, which are characteristic features of septic vasculopathy, were also observed. Direct immunofluorescence showed negative results...

Atlantic salmon skin tissues with and without scales were taken from two preferred sites of salmon louse (Lepeophtheirus salmonis) attachment, behind the dorsal fin (scaled) and from the top of the head (scaleless), respectively. Tissues were profiled by qPCR of 32 genes to study responses to copepodids, 4 days post infection (dpi), and during the moult of copepodids to the chalimus stage, at 8 dpi. Basal/constitutive differences were found for many immune-related genes between the two skin sites; e.g., mannose binding protein C was over 100 fold higher expressed in the scaled skin from the back in comparison to the skin without scales from the head...

Approximately 200 human papillomaviruses (HPVs) infect human epithelial cells, of which the alpha and beta types have been the most extensively studied. Alpha HPV types mainly infect mucosal epithelia and a small group of these causes over 600,000 cancers per year worldwide at various anatomical sites, especially anogenital and head-and-neck cancers. Of these the most important is cervical cancer, which is the leading cause of cancer-related death in women in many parts of the world. Beta HPV types infect cutaneous epithelia and may contribute towards the initiation of non-melanoma skin cancers...
