Vibrio alginolyticus causes soft tissue and bloodstream infection; little systematically collected clinical and epidemiological information is available. In the USA, V. alginolyticus infections are reported to the Cholera and Other Vibrio Illness Surveillance system. Using data from 1988 to 2012, we categorised infections using specimen source and exposure history, analysed case characteristics, and calculated incidence rates using US Census Bureau data. Most (96%) of the 1331 V. alginolyticus infections were from coastal states...

Staphylococcus aureus must rapidly adapt to a variety of carbon and nitrogen sources during invasion of a host. Within a staphylococcal abscess, preferred carbon sources such as glucose are limiting, suggesting that S. aureus survives through the catabolism of secondary carbon sources. S. aureus encodes pathways to catabolize multiple amino acids, including those that generate pyruvate, 2-oxoglutarate, and oxaloacetate. To assess amino acid catabolism, S. aureus JE2 and mutants were grown in complete defined medium containing 18 amino acids but lacking glucose (CDM)...

Hossam El-Din Ali Ismail, Mohamed Hassan El Fahar
Introduction: The sensory loss and alteration of the shape of the foot make the foot liable to trauma and pressure, and subsequently cause more callus formation, blisters, and ulcers. Foot ulcers usually are liable to secondary infection as cellulitis or osteomyelitis, and may result in amputations. Foot ulcers are a major problem and a major cause of handicaps in leprosy patients. The current study is to present our clinical experience and evaluate the use of sural flap with posterior tibial neurovascular decompression (PTND) in recurrent foot ulcers in leprosy patients...

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...

William F Wright, Manu Rajachandran
Leo Buerger, MD, was the first to describe dependent rubor associated with marked atherosclerosis. Historically, dependent rubor has been described as erythromelalgia (or erythromelia), and terms such as chronic rubor, reactionary rubor, induced rubor, and hyperemic response have also been used to describe this sign associated with peripheral vascular disease. This brief review will reacquaint physicians with the Buerger test, which is used to assess arterial sufficiency, as well as erythromelalgia, and the proposed mechanisms responsible for erythromelalgia...

BACKGROUND: The Bengal Bay clone, ST772-MRSA-V, associated with multi-drug resistance, Panton-Valentine leukocidin (PVL) and skin and soft tissue infections, is emerging worldwide. In Norway, a country with low prevalence of meticillin-resistant Staphylococcus aureus (MRSA), increased occurrence of ST772-MRSA-V has also caused hospital outbreaks. The conserved nature of this clone challenged the outbreak investigations. AIM: To evaluate the usefulness of S. aureus protein A (spa) typing, multiple-locus variable number tandem repeat fingerprinting/analysis (MLVF/MLVA) and pulsed-field gel electrophoresis (PFGE) when investigating outbreaks with a conserved MRSA clone...

Dolors Rodríguez-Pardo
Gram-positive infections are currently a therapeutic challenge because of the emergence of strains resistant to first-line antibiotics. Consequently, in the last few years, new antibiotics have been developed with activity against multiresistant Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus and strains with intermediate sensitivity to vancomycin. Among the new antibiotics approved for the treatment of these microorganisms, dalbavancin is a semisynthetic lipoglycopeptide derived from teicoplanin, but has a superior efficacy profile to the latter...

Dalbavancin is a semisynthetic lipoglycopeptide approved for the treatment of acute skin and soft tissue infections due to Gram-positive microorganisms susceptible to this antimicrobial agent. The FDA (Food and Drug Administration) and the EUCAST (European Committee on Antimicrobial Susceptibility Testing) have established clinical breakpoints to interpret the results of the antibiogram (expressed as MIC [minimum inhibitory concentration]) with approved doses (1g intravenously [IV] followed by 0.5g IV at day 8 or 1...

The use of linezolid to treat gram-positive cocci infections is increasing in France. Linezolid is approved in pneumonia and complicated skin and soft tissue infections. Overuse and misuse of linezolid can favor the emergence and spreading of linezolid-resistant strains. We aimed to assess the appropriateness of linezolid use in French hospitals. This is a multicenter, retrospective study conducted in three tertiary care hospitals. Appropriateness of linezolid indications and adequacy (composite score concerning dosage, route of administration and blood monitoring) were assessed...
