The Norwegian aquaculture of Atlantic salmon (Salmo salar L.) is hampered by ulcerative disorders associated with bacterial infections. Chronic ulceration may provide microenvironments that disturb the normal microbial biodiversity of external surfaces. Studying the composition of microbial communities in skin ulcers will enhance our understanding of ulcer aetiology. To achieve this, we tested marine farmed Atlantic salmon and sampled the base and edge of ulcers at the end of winter (April) and end of summer (September), in addition to skin mucus of healthy individuals...

Bone infection and nonunion are the main orthopedic and traumatic complications whose treatment remains a challenge because multiple factors are involved in the rate of failures when you try to correct them. Knowing these factors were the problem that caused the research through a prospective longitudinal study of 83 patients of 43.3 ± 16.1 years old. They were treated for aseptic and septic nonunion, osteomyelitis, osteitis, malunion or infected joint replacement. The cases were classified with or without postoperative complications and outcome related to systemic and local factors taken prognostic model Cierny-Mader as factors affecting immune surveillance, metabolism and local vascularization...

Thymosin beta 4 (Tβ4) is a peptide that has been shown in dermal, corneal, and cardiac preclinical injury models to potentially affect tissue protection, regeneration, and repair. Sacrococcygeal pilonidal sinus disease (SPSD) is a chronic inflammatory disorder associated with a high incidence of recurrence, chronic fistulation, and a challenging postoperative surgical wound healing process. Retrospectively, an immunohistochemical analysis was conducted to evaluate endogenous Tβ4 expression in excisional skin biopsies from patients with SPSD...

Indoleamine 2,3-dioxygenase (IDO) has emerged as a pivotal enzyme for mediating immune tolerance. Because IDO metabolizes tryptophan into kynurenine, the plasma kynurenine/tryptophan (Kyn/Trp) ratio has been widely used as a marker of systemic IDO. Here, we evaluated the clinical value of using the plasma Kyn/Trp ratio to estimate cell-mediated immune responses to tuberculin skin testing and risk of new bacterial infection. We also compared the Kyn/Trp ratio to a novel IDO marker, the IDO median fluorescence index (MFI) of peripheral blood mononuclear cells, which was determined by flow cytometry...

Stings from the hydrozoan species in the genus Physalia cause intense, immediate skin pain and elicit serious systemic effects. There has been much scientific debate about the most appropriate first aid for these stings, particularly with regard to whether vinegar use is appropriate (most current recommendations recommend against vinegar). We found that only a small percentage (≤1.0%) of tentacle cnidae discharge during a sting event using an ex vivo tissue model which elicits spontaneous stinging from live cnidarian tentacles...

Eczematous lesions of atopic dermatitis (AD) patients are known to be a source of Staphylococcus aureus (SA) transmission and might be a reservoir for community-associated methicillin-resistant SA (MRSA). The BD Max StaphSR (BD-SR) is a fully automated, multiplex real-time PCR assay for the direct detection and differentiation of SA and MRSA from nasal swab samples. We evaluated the detection rates of SA and MRSA from skin lesions of outpatients with AD using the BD-SR assay, and determined the usefulness of the BD-SR assay...

Needle-free jet injections constitute a crucial method for drug delivery. A novel liquid drug delivery system has been proposed recently, in which pressure atomizes liquid before delivering that atomized liquid to the patient's body; however, the mechanism and efficiency of the system are unclear. This study explored the shot delivery pressure, penetration depth, and cumulative amount of permeation of this system. This system was used to deliver 0.5% (w/v) methylene blue to agarose phantoms at various shot delivery pressures...
