Morbihan disease (MD), also referred to as solid facial edema, or rosacea lymphedema, is a rare disorder that involves chronic erythema and solid edema of the cheeks, eyelids, forehead and glabella and may arise as a complication of acne vulgaris or rosacea. Of note, it may be the only initial presenting symptom of these associated diseases.1,2 Few cases have been described in the literature, since its first description by Robert Degos in 1957. The condition is characterized by its chronicity, a typical clinical appearance, and the lack of specific histopathologic or laboratory findings...

Acne is one of the most prevalent skin conditions seen by dermatologists. The cosmetic sequelae of severe acne, including scarring and pigmentation, have a profound psychological impact on those in icted. Topical (eg, retinoids, antibiotics, dapsone, hydroxyacids) and oral treatments (eg, antibiotics and/or spironolactone) are often bene cial to control acne or in the instance of oral isotretinoin use, rid the acne permanently; however, these treatments have very little affect on the ultimate cosmetic outcome of the acne scarring and skin texture that results...

Nitric oxide (NO) is a diatomic gas that is synthesized within and released by multiple host cell types functioning to provide a variety of physiologic and homeostatic effects. Nitric oxide exhibits a variety of effects that relate significantly with outcomes that can provide therapeutic benefit if properly formulated and released. These include anti-inflammatory, immunomodulatory, antimicrobial, vasodilatory properties, and effects that are beneficial to wound healing. Lack of antibiotic resistance appears to be one major advantage of topically delivered NO...

BACKGROUND: The gastrointestinal motility is affected by gut microbiota and the relationship between them has become a hot topic. However, mechanisms of microbiota in regulating motility have not been well defined. We thus investigated the effect of microbiota depletion by antibiotics on gastrointestinal motility, colonic serotonin levels, and bile acids metabolism. METHODS: After 4 weeks with antibiotics treatments, gastrointestinal and colon transit, defecation frequency, water content, and other fecal parameters were measured and analyzed in both wild-type and antibiotics-treated mice, respectively...

Background Treatment of musculoskeletal infections principally consists of radical surgical debridement and systemic administration of antibiotics. Additional local antibiotic therapy is not yet generally established, and lacks evidence-based proof of efficacy. Nonetheless, there are a variety of practical approaches, as most specialised departments are unwilling to forego this option. The established polymethylmetacrylate (PMMA) carrier system has a number of practical disadvantages. This has led to the increased use of absorbable carrier systems, and those based on calcium sulphate have given particularly encouraging results...

Aminoglycosides are a family of critically important antibiotics for the treatment of serious infections including multidrug-resistant pathogens. However, clinical use of aminoglycoside antibiotics is compromised by bacterial biofilm formation at subinhibitory concentrations or adverse side effects such as ototoxicity and nephrotoxicity at high antibiotic doses. Preparation of aminoglycoside formulation that allows on-demand drug delivery is a solution to this sticky issue. Here, we designed a new type of aminoglycoside hydrogels by cross-linking oxidized polysaccharides such as dextran, carboxymethyl cellulose, alginate, and chondroitin using aminoglycosides as cross-linkers...

Members of the Vibrionaceae family are often associated with chitin-containing organisms, and they are thought to play a major role in chitin degradation. The purpose of the present study was to determine how chitin affects the transcriptome and metabolome of two bioactive Vibrionaceae strains, Vibrio coralliilyticus and Photobacterium galatheae. We focused on chitin degradation genes and secondary metabolites based on the assumption that these molecules in nature confer an advantage to the producer. Growth on chitin caused upregulation of genes related to chitin metabolism and of genes potentially involved in host colonization and/or infection...

Peritoneal dialysis exit site infections caused by Pseudomonas spp. are difficult to treat and can lead to peritonitis and/or modality failure. Effective alternative or adjunct non-antibiotic antimicrobial agents could improve treatment as well as reduce the use of antibiotics and contribute to a reduction in antibiotic selection pressure and the further development of antibiotic resistance. Vinegar is popularly promoted as a topical antimicrobial agent and has been recommended as an adjunct treatment for Pseudomonas exit site infections in PD patients...

REVIEW
Sami K Saikaly, Amor Khachemoune
For centuries, honey has been utilized for wound healing purposes. In recent times, this specific topic has become a field of interest, possibly due to the advent of antibiotic resistance in microbial pathogens. With constant technological advancement, the information regarding honey's mechanisms of action on wound healing has accumulated at a rapid pace. Similarly, clinical studies comparing honey with traditional wound care therapies are steadily emerging. As a follow-up to a previous review published in the journal in 2011, the current review article outlines publications regarding honey and wound healing that have been published between June 2010 and August 2016...

: Biofilms on wound surfaces are treated topically with hyperosmotic agents such as medical-grade honey and cadexomer iodine; in some cases, these treatments are combined with antibiotics. Tissue repair requires oxygen, and a low pH is conducive to oxygen release from red blood cells and epithelialization. We investigated the variation of dissolved oxygen concentration and pH with biofilm depth, and the variation in oxygen consumption rates when biofilms are challenged with medical-grade honey or cadexomer iodine combined with vancomycin or ciprofloxacin...

Biofilms are regarded as one of the most challenging topics of modern biomedicine, and they are potentially responsible for over 80% of antibiotic-tolerant infections. Biofilms have displayed an exceptionally high tolerance for chemotherapy, which is thought to be multifactorial. For instance, the matrix provides a physical barrier that decreases the penetration of antibiotics into the biofilm. Also, cells within the biofilms are phenotypically diverse. Likely, biofilm resilience arises from a combination of these and other, yet unknown, mechanisms...

In Germany, the reported syphilis prevalence has increased continuously since 2010, with a total of 6834 syphilis cases being reported in 2015. The largest increase of reported syphilis occurred in men who have sex with men (MSM). The antibiotic agent of choice for treatment of syphilis is still penicillin. There are no penicillin-resistant Treponema pallidum strains. Alternatives are ceftriaxone and doxycycline. In Germany, azithromycin is not approved for treatment of syphilis; however, therapy failures are increasingly reported...

BACKGROUND: Deep sternal wound infection (DSWI) is a devastating complication that increases morbidity and death in cardiac surgical patients. Vancomycin is often administered intravenously for antibiotic prophylaxis in cardiac operations. Many cardiac surgeons also apply vancomycin paste topically to the sternal edges. We examined the effect of vancomycin paste on the incidence of DSWI in patients undergoing elective cardiac operations. METHODS: We retrospectively reviewed the medical records of all patients from 2003 to 2015 who underwent coronary artery bypass grafting, valve, or combined coronary artery bypass grafting and valve operations at a single institution...

Driven by the need to engineer robust surface coatings for medical devices to prevent infection and sepsis, incorporation of nanoparticles has surfaced as a promising avenue to enhance non-fouling efficacy. Microbial synthesis of such nanoscale metallic structures is of substantive interest as this can offer an eco-friendly, cost-effective, and sustainable route for further development. Here we present a Mucor hiemalis-derived fungal route for synthesis of silver nanoparticles, which display significant antimicrobial properties when tested against six pathological bacterial strains (Klebsiella pneumoniae, Pseudomonas brassicacearum, Aeromonas hydrophila, Escherichia coli, Bacillus cereus, and Staphylococcus aureus) and three pathological fungal strains (Candida albicans, Fusarium oxysporum, and Aspergillus flavus)...
