Malassezia species are natural inhabitants of the healthy skin. However, under certain conditions, they may cause or exacerbate several skin diseases. The ability of this fungus to colonize or infect is determined by complex interactions between the fungal cell and its virulence factors. This study aims to evaluate "in vitro" the hydrophobicity levels, the adherence on a plastic surface and the biofilm formation of 16 clinical isolates of Malassezia furfur. Cellular surface hydrophobicity (CSH) levels were determined by two-phase system...

We performed a retrospective chart review for all cases of recurrent Stevens Johnson Syndrome (SJS) from March 2013 to March 2016. Nine children had 29 episodes of SJS or incomplete SJS; all children were male and 8 (88%) were white. Episodes affected mucus membranes with minimal skin involvement. Mycoplasma infections and HLA-B27/-B51 were common.

Superficial fungal infections are a major epidemiological issue with increasing prevalence and are a common global problem. This article describes experimental therapy of superficial fungal skin infection using low-temperature plasma. Groups of guinea pigs were artificially infected with Trichophyton mentagrophytes SK 3286 dermatophyte and treated with plasma produced by a DC cometary discharge with an inserted grid. The course of infection was a week shorter and milder in animals treated by plasma than that in nontreated animals, the significant lowering of dermatophytic germs also occurred in the treated group...

Grapevine red blotch-associated virus (GRBaV) is a major threat to the wine industry in the USA. GRBaV infections (aka red blotch disease) compromise crop yield and berry chemical composition, affecting the flavor and aroma properties of must and wine. In this study, we combined genome-wide transcriptional profiling with targeted metabolite analyses and biochemical assays to characterize the impact of the disease on red-skinned berry ripening and metabolism. Using naturally infected berries collected from two vineyards, we were able to identify consistent berry responses to GRBaV across different environmental and cultural conditions...

Hyptis umbrosa (syn. Mesosphaerum sidifolium) (Lamiaceae Family) has been used to treat several conditions such as gastrointestinal disorders, skin infections, nasal congestion, fever and cramps. The objective of this study was to evaluate the chemical composition, analgesic and anti-inflammatory profiles of ethanol extract from leaves of Hyptis umbrosa (EEB). HPLC-DAD was used to determine the fingerprint chromatogram of the extract. Male Swiss mice were orally pretreated with EEB (100, 200 or 400 mg/kg; 60 min before initiating algesic stimulation) and antinociceptive activity was assessed using the acetic acid-induced writhing model, formalin test and hyperalgesia induced by glutamate or capsaicin...

PURPOSE: The impact of an antimicrobial stewardship initiative on time to first antibiotic dose and clinical outcomes in bacteremic patients was evaluated. METHODS: A single-center, retrospective study was conducted for adult inpatients who received antibiotics before and after implementation of a rapid administration of antimicrobials by an infectious diseases specialist (RAIDS) protocol. Patients admitted to an inpatient service from June to October 2011 (pre-RAIDS protocol) and from December 2011 to February 2012 (post-RAIDS protocol) were eligible for inclusion if (1) they were age 18 years or older, (2) their infection occurred two or more days after hospital admission, and (3) they had a blood culture growing an organism other than common skin contaminants (i...

BACKGROUND: Vitamin C (vit C) is an essential dietary nutrient, which is a potent antioxidant, a free radical scavenger and functions as a cofactor in many enzymatic reactions. Vit C is also considered to enhance the immune effector function of macrophages, which are regarded to be the first line of defence in response to any pathogen. The THP-1 cell line is widely used for studying macrophage functions and for analyzing host cell-pathogen interactions. RESULTS: We performed a genome-wide temporal gene expression and functional enrichment analysis of THP-1 cells treated with 100 μM of vit C, a physiologically relevant concentration of the vitamin...

Purpura fulminans (PF) is a dreadful and frequent complication of Neisseria meningitidis invasive infection, and is associated with a high mortality rate. This syndrome begins with dermal microvessels thrombosis that rapidly lead to hemorrhagic skin necrosis. In this review, we discuss the prothrombotic events occurring during meningococcal infection. Moreover, recent data from an experimental mouse model have highlighted the critical role of the meningococcus adhesion to the endothelium in the development of PF lesions, thus opening new therapeutic perspectives...

INTRODUCTION: Gastrointestinal complications are common after renal transplantation, including oral lesions, esophagitis, gastritis, diarrhea, and colon carcinoma. The differential diagnosis is difficult in this scenario because multiple factors such as drugs, infections, and preexisting gastrointestinal disease come into play. CASE PRESENTATION: We report a case of varicella zoster virus-induced pancreatitis and hepatitis in a renal transplant recipient. The patient underwent renal transplantation 3 years earlier and now presented with severe pain in the epigastrium radiating to his back and had raised serum lipase levels and skin lesions characteristic of varicella...

BACKGROUND: Currently, various methods of skin closures are used in contaminated and dirty abdominal wounds without solid, evidence-based guidance. This study investigates whether closure methods affect surgical site infection (SSI) and other incisional complications. We hypothesize that open management of the skin would have the lowest complications, including SSI. PATIENTS AND METHODS: Patients age ≥18 who underwent trauma laparotomy (TL) or damage control laparotomy (DCL) from 2008-2013 and had class III/IV wounds were included...

BCG vaccination sensitises cattle to bovine tuberculin which compromises the use of the current bovine TB surveillance tests. Although the performance of a blood test (that utilises antigens expressed by Mycobacterium bovis but not by BCG) capable of discriminating infected from vaccinated animals (DIVA interferon-gamma test, DIT) has been evaluated in naturally infected TB field reactors, there is a need to perform similar analysis in a BCG vaccinated/M. bovis infected population. Furthermore, we explored different scenarios under which a DIT may be implemented alongside BCG vaccination: (i) serial testing to resolve potential false positive skin test results; or (ii) standalone test to replace the single intradermal comparative cervical tuberculin skin test (SICCT)...
