Filter by:An RCT will be set up to compare outcomes between two groups of hand surgery patients. These are: • Emergency hand surgery patients - randomized to either absorbable or non-absorbable suture. The primary outcomes investigated will be: • Infection occurrence The secondary outcomes will be: - Scar appearance at 1 week and 6-8 weeks (assessed from photographs and scar scoring scale) - Wound inflammation as a percentage of wound length at day 7 post surgery. - Patient symptoms at 1 week (assessed from patient questionnaire) - Patient symptoms at 6-8 weeks (assessed from patient questionnaire) - QDASH Score at 1 week (assessed from patient questionnaire) - QDASH score at 6-8 weeks (assessed from patient questionnaire) - Occurrence of other complications (assessed from the above photographs, the above questionnaires and from nurse and doctor led reports of wound breakdown and other complications)
This study will investigate the tissue distribution of azithromycin in healthy, artificially inflamed and actually infected tissue of humans.
This is an exploratory study to evaluate the effect of adjunctive clindamycin in the treatment of skin and soft-tissue infections due to Staphylococcus aureus in patients from Sierra Leone. The study hypothesizes that clindamycin, when added to routine treatment, will lead to a more rapid clinical resolution and less frequent recurrences of infection.
Among multidrug-resistant bacteria, Methicillin-resistant Staphylococcus aureus (MRSA) isolates were recognized to be an important mortality factor in hospital infections and a major concern in health-care and community settings . The antibiotic-resistant of S. aureus is extended by various bacterial strategies, including limiting uptake of the drug, alteration of the drugtargets, production of druginactivating enzymes and the activation of efflux pumps that effectively remove antibiotics . Relying on the type of antibiotics, bacteria can apply one or more strategies. Specifically, localization of resistance genes in transferable genetic elements, such as plasmid and transposons , causing Horizontal transfer of resistance genes between bacterial strains . MRSA strains are resistant to nearly all beta-lactam antibiotics by producing an alternative penicillin-binding protein known as PBP2a . This protein is encoded by the mecA gene and has a low affinity to manybeta-lactam antibiotics. Furthermore, these strains often show resistance to a wide range of antibiotics . The use of fluoroquinolone for the effective infectious therapy is limited by presence of fluoroquinolone resistance . There are two mechanisms causing resistance to fluoroquinolone. The first one is attributed to mutations occurring in the quinolone-resistance determining region (QRDR) of topoisomerase IV encoded by grlA/grlB and DNA gyrase encoded by gyrA/gyrB; these mutations decrease the affinity ofthe drug. The other mechanism is mediated by efflux pumps which is less recognized . Recently, several efflux pumps have been identified for S. aureus including efflux pumps encoded by chromosome or plasmids. The efflux pumps norA, norB, norC, mdeA, sepA, mepA, sdrM and lmrS are encoded by chromosome while qacA/B, qacG, qacH, qacJ and smr are plasmid-encoded . Efflux pumps could be specialized for specific substrate or mobilized a wide varieties of different antibiotic classes . Despite, efflux pumps can potentially increase resistance to antibiotics in clinical isolates of S. aureus, few studies have been evaluated the individual and collective participation of the efflux system in resistant isolates . Therefore the aim of the study is to detect ciprofloxacin resistant strains of staphylococcus aureus isolates and to detect efflux pump genes ( norA , norB and norC ) mediating resistance in such strains.
Identify the cutaneous microbiota on a cutaneous lesion (cellulite, wound, rash, etc.) on a swab, biopsies or abscess puncture and on "healthy" skin on a skin swab performed for cutaneous mapping to search for staphylococcal deposits.
