PURPOSE OF REVIEW: Methicillin-resistant Staphylococcus aureus (MRSA) has become a major public health issue worldwide over the last years. MRSA is frequently implicated in the development of skin and soft tissue infections, leading to significant increases in morbidity, mortality and overall healthcare costs. RECENT FINDINGS: In order to face the threat of MRSA, major changes in clinical management of skin and soft tissue infections are required. The identification of populations at risk for the acquisition of infections due to MRSA, together with the improvement of the diagnostic techniques, is paramount...

A problem of community-acquired Staphylococcus aureus skin infections emerged in the French armed forces in 2004, in a malaria-endemic areas. The high incidence rate led us to evaluate military staff practices. This was a cross-sectional survey of doctors and nurses deployed as officers in French Guyana since 2006. The definition of skin and soft-tissue infection came from the criteria for epidemiological surveillance of the armed forces. We studied the management of antibiotic therapy and its related difficulties...

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...

Group A streptococcus and Staphylococcus aureus are the most common bacterial etiologies of skin and soft tissue infections that range in virulence from very mild to limb/life threatening. Antibiotic coverage recommendations are varying and subject to controversy. Antibiotic resistance patterns are evolving with many different biochemical mechanisms. Rapid bacterial identification using mass spectrometry is on the horizon. Therapeutic considerations should include cost and adherence issues.

Mycobacterium fortuitum group (M. fortuitum), also known as rapidly growing Mycobacteria, can cause pyogenic infections in human beings, most commonly in immunocompromised patients. Herein, we present a 40-year-old immunocompetent male patient who underwent planned excision of a sebaceous cyst in the abdominal wall. He suffered from tender erythematous lesions with purulent discharge around the healing wound that developed 2 weeks after surgery. Gram stain, bacterial and fungal culture results of the wound were negative...

Streptococcus pyogenes secretes many toxins that facilitate human colonization, invasion, and dissemination. NADase (SPN) and streptolysin O (SLO) are two toxins that play important roles in pathogenesis. We previously showed that increased production of SPN and SLO in epidemic serotype M1 and M89 S. pyogenes strains is associated with rapid intercontinental spread and enhanced virulence. The biological functions of SPN and SLO have been extensively studied using eukaryotic cell lines, but the relative contribution of each of these two toxins to pathogenesis of epidemic M1 or M89 strains remains unexplored...

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: Non-viral injecting-related injuries and diseases (IRID), such as abscesses and vascular damage, can result in significant morbidity and mortality if untreated. There has been no systematic assessment of the prevalence of non-viral IRID among people who inject drugs; this review aimed to address this gap, as well as identify risk factors for experience of specific IRID. METHODS: We searched MEDLINE, Embase and CINAHL databases to identify studies on the prevalence of, or risk factors for, IRID directly linked to injecting in samples of people who inject illicit drugs...

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 exam 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...
