BACKGROUND: Bacterial skin and soft tissue infections (SSTIs) are a health issue for people who inject drugs (PWID). There is a lack of evidence on the associations between harm reduction (HR) uptake and SSTIs. This paper examines the associations between the uptake of injecting equipment (IE) and opiate substitution treatment (OST) on SSTIs among PWID, and the injecting behaviours associated with having had an SSTI. This is the first large-scale, national study to examine the association between IE uptake and SSTIs...

Genetic variants are considered as one of the main determinants of the concentration of serum lipids and coronary artery disease (CAD). Polymorphisms in the Apolipoprotein (Apo) AI-CIII-AIV gene cluster has been known to affect the concentrations of various lipid sub-fractions and the risk of CAD. The present study assessed associations between polymorphisms of the Apo AI-CIII-AIV gene cluster, [ApoA-I,-75G > A, (rs1799837); ApoC-III 3238C > G, (SstI), (rs5128) and ApoA-IV, Thr347Ser(347A > T), (rs675)] with serum lipids and their contributions to CAD in North Indian population...

The aim of this prospective study was to evaluate the performance of the Polymerase Chain Reaction (PCR) tool Xpert MRSA/SA SSTI test (Cepheid, Sunnyvale, CA, USA) on periprosthetic samples from a cohort of patients with suspected prosthetic joint infection (PJI). Seventy adult patients were included in this prospective study. On the basis of the preoperative evaluation, 39 patients were clinically considered to have a PJI, whereas 31 were presumed to suffer from an aseptic mobilization of the implant. Xpert MRSA/SA SSTI identified 4 out of 4 MRSA, 7 out of 7 MSSA, and 14 out of 16 methicillin resistant CoNS...

Only a few, relatively cumbersome animal models enable long-term Gram-negative bacterial infections that mimic human situations, where untreated infections can last for weeks. Here, we describe a simple murine cutaneous abscess model that enables chronic or progressive infections, depending on the subcutaneously injected bacterial strain. In this model, Pseudomonas aeruginosa cystic fibrosis epidemic isolate LESB58 caused localized high-density skin and soft tissue infections and necrotic skin lesions for up to 10 days but did not disseminate in either CD-1 or C57BL/6 mice...

Ultrasound imaging is a rapid and noninvasive tool ideal for the imaging of soft tissue infections and is associated with a change of clinician management plans in 50% of cases. We developed a realistic skin abscess diagnostic and therapeutic training model using fresh frozen cadavers and common, affordable materials. Details for construction of the model and suggested variations are presented. This cadaver-based abscess model produces high-quality sonographic images with internal echogenicity similar to a true clinical abscess, and is ideal for teaching sonographic diagnostic skills in addition to the technical skills of incision and drainage or needle aspiration...

Community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) are the cause of a severe pandemic consisting primarily of skin and soft tissue infections. The underlying pathomechanisms have not been fully understood and we report here a mechanism that plays an important role for the elevated virulence of CA-MRSA. Surprisingly, skin abscess induction in an animal model was correlated with the amount of a major cell wall component of S. aureus, termed wall teichoic acid (WTA). CA-MRSA exhibited increased cell-wall-associated WTA content (WTA(high)) and thus were more active in inducing abscess formation via a WTA-dependent and T-cell-mediated mechanism than S...

Vibrio vulnificus can cause severe skin and soft tissue infection (SSTI). The pathogen is an opportunistic marine bacterium that is likely to infect patients with chronic liver disease, patients in an immunocompromised state, and those in end-stage renal disease. V. vulnificus gains entry through soft tissues by direct penetration of a wound by infected marine organisms, such as raw oysters, shellfish and other seafood, or by exposing a wound to contaminated water. Despite its ease of entry, V. vulnificus necrotising fasciitis with compartment syndrome has rarely been described...

Mycobacterium kansasii is a slow growing acid-fast non-tuberculosis mycobacterium. It most commonly causes pulmonary disease with tuberculosis-like manifestations. Mycobacterium kansasii-induced skin and soft tissue infections (SSTIs) are very uncommon, especially in the absence of obvious risk factors. In this report, we present a rare case of M. kansasii-associated SSTI complicated by tendonitis and osteomyelitis in an immunocompetent patient. This case highlights the importance of considering non-tuberculosis mycobacteria while investigating chronic, relapsing, non-healing SSTIs and osteomyelitis...

Mast cells are located at host interfaces, such as the skin, and contribute to the first-line defense against pathogens by releasing soluble mediators, including those that induce itching and scratching behavior. Here, we show that delta-hemolysin (Hld) and phenol soluble modulins (PSMs) PSMα1 and PSMα3, but not alpha-hemolysin (Hla) or Panton-Valentine leukocidin (PVL), induce dose-dependent tryptase, and lactate dehydrogenase (LDH) release by the HMC-1 human mast cell line. Using supernatants from isogenic strains, we verified that tryptase and LDH release was Hld- and PSMα-dependent...

BACKGROUND: Primary care providers often manage skin abscesses in the outpatient setting. Estimating the size and depth of an abscess, and distinguishing abscess from cellulitis by clinical examination can be challenging due to surrounding firm tissue induration. Definitive treatment of abscess requires incision and drainage, and the approach chosen may be altered by abscess size, depth, and surrounding neurovascular structures. METHODS: For 31 consecutive patients seen in the primary care outpatient clinic, we prospectively compared the estimated size of skin abscesses by clinical examination with that determined by ultrasound...

Methicillin-resistant Staphylococcus aureus (MRSA) is an important cause of pneumonia in ventilated patients. Our objective was to evaluate the GeneXpert MRSA/SA SSTI Assay (Xpert MRSA/SA) (Cepheid, Sunnyvale, CA) for use in lower respiratory tract (LRT) specimens for rapid MRSA detection and to determine the potentially saved antibiotic-days if a culture-based identification method was replaced by this assay. Remnant LRT samples from ventilated patients submitted to the microbiology laboratory for routine culture were tested using conventional culture and Xpert MRSA/SA...
