BACKGROUND: Most of surgical site infections (SSI) are caused by commensal and pathogenic agents from the patient's microbiota, which may include antibiotic resistant strains. Pre-surgical asepsis of the skin is one of the preventive measures performed to reduce SSI incidence and also antibiotic resistance dissemination. However, in veterinary medicine there is no agreement on which biocide is the most effective. The aim of this study was to evaluate the effectiveness of two pre-surgical skin asepsis protocols in dogs...

BACKGROUND: With increasing rates of virulent drug resistant organisms, MRSA (methicillin-resistant Staphylococcus aureus) decolonization has been demonstrated to decrease infection rates. Recent research has shown the antiseptic povidone-iodine to be equally effective and potentially cost saving compared to intranasal mupirocin. This study's purpose is to evaluate the incidence of MRSA colonization in a more rural community-based population, rates of infection on a mupirocin decolonization protocol, and develop a cost analysis model to compare costs of utilizing povidone-iodine...

BACKGROUND: There is a burglar association between diabetes and periodontitis. Many studies has shown that periodontitis treatment can help improving glycemic control in diabetes patients but little evidence of non-surgical treatment benefit is available in sub Saharan african diabetes patients. We aimed to assess the effects of non-surgical periodontal treatment (NSPT) of chronic periodontitis on glycaemic control in poorly controlled type 2 diabetes patients (T2D) in a sub-Saharan Africa urban setting...

Implant-based breast reconstruction accounts for more than 70% of all breast reconstructions, and breast augmentation is the most commonly performed cosmetic operation annually. The clinically significant impact of infection and capsular contracture after breast implant surgery has brought clinicians to create infection reduction protocols for both oncologic and cosmetic operations alike. The use of triple-antibiotic saline irrigation has become a recommended intraoperative maneuver within these protocols to minimize surgical site infections, but the constituents of the irrigation, its individual efficacy, and the acceptability of including povidone-iodine within irrigation recipes have been debated...

This study is a comprehensive evaluation of praziquantel (PZQ) behavior upon grinding considering the influence of milling temperature (cryogenic vs room temperature), frequency and time and presence of polymers (milled raw PZQ vs comilled PZQ/povidone and PZQ/crospovidone at 50:50 w/w) on two experimental responses (residual crystallinity and PZQ recovery). To this aim a full factorial design was set up and the responses of the experimental design were statistically assessed. The powder temperature, measured in different milling conditions, was found to increase with increasing milling frequency and time, up to a maximum recorded value of 46...

In the fourth quarter of 2017, the US FDA reviewed and approved a request by one of the breast implant manufacturers for a change in the Directions for Use (DFU) that removed warnings regarding the use of Betadine (povidone-iodine [PI] 10% solution, 1% available iodine [Purdue Frederick Company, Stamford, CT], also available in generic formulations [Aplicare, Inc., Meriden, CT]). Previously, in 2000, there were concerns by the FDA that PI would degrade the silicone elastomer shell. This change in the DFU represents an important advance that will benefit patients through the permitted use of PI to reduce the risk of bacterial contamination of implant surfaces...

The morphological features of pluronic F127 at various concentrations were investigated and 20% aqueous pluronic F127 solution was chosen for the preparation of biomembrane. The pluronic solution was mixed with appropriate concentration of excipients such as PVA, Povidon S630, PG, Nipagin, Neomycin and Panthenol. The prepared pluronic F127 was thermosensitive, a liquid phase at low temperatures (≤10 °C) but converting into gel at temperatures above 20 °C, and formed stable biomembrane at 37 °C. The neomycin impregnated pluronic membrane suppressed the bacterial growth on agar plate by the sustained release of neomycin...

BACKGROUND: The skin bacterium Propionibacterium acnes has been reported to be responsible for surgical site infections (SSIs). Skin disinfection before surgery therefore is of the utmost importance in the prevention of SSIs caused by skin bacteria. METHODS: We assessed the susceptibility of clinical isolates of two skin bacteria, P. acnes and Staphylococcus epidermidis, to disinfectants. RESULTS: The range of chlorhexidine digluconate (CHG) minimum inhibitory concentrations (MICs) for P...

BACKGROUND: Antiseptic and antibacterial solutions used for intraoperative irrigation are intended to kill bacteria and thereby decrease the incidence of surgical site infections. It is unknown if the concentrations and exposure times of irrigation solutions commonly used for prophylaxis in clean cases (povidone-iodine 0.35% for 3 minutes) are effective against bacteria in biofilm that are present in implant infections. Currently, povidone-iodine (0.35%), chlorhexidine (0.05%), sodium hypochlorite (0...

Background: Infection and capsular contracture are two of the most significant complications of breast-implant surgery. Both complications are associated with bacterial contamination of the implant surface. Plasma activation of the surface of a silicone breast implant changes its surface properties from water repelling (hydrophobic) to water absorbing (hydrophilic), thus making it possible for antibacterial irrigants to temporarily adsorb onto the implant surface. Objective: To support our hypothesis that by changing the surface properties we could render antibacterial irrigation more effective in inhibiting bacterial growth on a breast implant shell...
