    PMID: 6265744
    Cefotaxime [HR 756], a third generation cephalosporin with pronounced antibacterial activity
    against the Enterobacteriaceae, was assessed in serious and problem antibiotic resistant infection. Good clinical success was achieved without observed untoward effects. The study suggests that due to its properties, cefotaxime could be used as a first-line antibiotic provided that the clinical situation warrants the use of a cephalosporin or aminoglycoside.
    Key words - cefotaxime [HR 756], serious surgical infection, antibiotic resistant infection.

    Antibiotics are the pillar of surgery from prophylaxis to treatment; any failure is potentially a leading cause for increased morbidity and mortality. Robust data on the burden of SSI especially those due to antimicrobial resistance (AMR) show variable rates between countries and geographical regions but accurate estimates of the incidence of surgical site infections (SSI) due to AMR and its related global economic impact are yet to be determined. Quantifying the burden of SSI treatment is an incentive to sensitize governments, healthcare systems, and the society to invest in quality improvement and sustainable development. However in the absence of a unified epidemiologically sound infection definition of SSI and a well-designed global surveillance system, the end result is a lack of accurate and reliable data that limits the comparability of estimates between countries and the possibility of tracking changes to inform healthcare professionals about the appropriateness of implemented infection prevention and control strategies. This review aims to highlight the reported gaps in surveillance methods, epidemiologic data, and evidence-based SSI prevention practices and in the methodologies undertaken for the evaluation of the economic burden of SSI associated with AMR bacteria. If efforts to tackle this problem are taken in isolation without a global alliance and data is still lacking generalizability and comparability, we may see the future as a race between the global research efforts for the advancement in surgery and the global alarming reports of the increased incidence of antimicrobial-resistant pathogens threatening to undermine any achievement.

  4. Fulltext The antibacterial properties of Malaysian tualang honey against wound and enteric microorganisms in comparison to manuka honey
    Tan HT, Rahman RA, Gan SH, Halim AS, Hassan SA, Sulaiman SA, et al.
    BMC Complement Altern Med, 2009;9:34.
    PMID: 19754926 DOI: 10.1186/1472-6882-9-34
    Antibiotic resistance of bacteria is on the rise, thus the discovery of alternative therapeutic agents is urgently needed. Honey possesses therapeutic potential, including wound healing properties and antimicrobial activity. Although the antimicrobial activity of honey has been effectively established against an extensive spectrum of microorganisms, it differs depending on the type of honey. To date, no extensive studies of the antibacterial properties of tualang (Koompassia excelsa) honey on wound and enteric microorganisms have been conducted. The objectives of this study were to conduct such studies and to compare the antibacterial activity of tualang honey with that of manuka honey.

  5. Fulltext Impact of pharmacist-led antibiotic stewardship interventions on compliance with surgical antibiotic prophylaxis in obstetric and gynecologic surgeries in Nigeria
    Abubakar U, Syed Sulaiman SA, Adesiyun AG
    PLoS One, 2019;14(3):e0213395.
    PMID: 30845240 DOI: 10.1371/journal.pone.0213395
    BACKGROUND: Inappropriate and excessive use of surgical antibiotic prophylaxis are associated with the emergence of antibiotic resistance. Antibiotic prophylaxis malpractices are common in obstetrics and gynecology settings and antibiotic stewardship is used to correct such malpractice.

    OBJECTIVE: To evaluate the impact of antibiotic stewardship interventions on compliance with surgical antibiotic prophylaxis practice in obstetrics and gynecology surgeries.

    METHOD: A prospective pre- and post-intervention study was conducted in two tertiary hospitals between May and December 2016. The duration of the each period was 3 months. Antibiotic stewardship interventions including development of a protocol, educational meeting and audit and feedback were implemented. Data were collected using the patient records and analyzed with SPSS version 23.

    RESULTS: A total of 226 and 238 surgical procedures were included in the pre- and post-intervention periods respectively. Age, length of stay and estimated blood loss were similar between the two groups. However, specialty and surgical procedures varied significantly. There was a significant increase in compliance with timing (from 14.2% to 43.3%) and duration (from 0% to 21.8%) of surgical antibiotic prophylaxis after the interventions. The interventions significantly reduced the prescription of third generation cephalosporin (-8.6%), redundant antibiotic (-19.1%), antibiotic utilization (-3.8 DDD/procedure) and cost of antibiotic prophylaxis (-$4.2/procedure). There was no significant difference in the rate of surgical site infection between the two periods. Post-intervention group (OR: 5.60; 95% CI: 3.31-9.47), elective surgery (OR: 4.62; 95% CI: 2.51-8.47) and hospital attended (OR: 9.89; 95% CI: 5.66-17.26) were significant predictors of compliance with timing while elective surgery (OR: 12.49; 95% CI: 2.85-54.71) and compliance with timing (OR: 58.55; 95% CI: 12.66-270.75) were significantly associated with compliance to duration of surgical antibiotic prophylaxis.

    CONCLUSION: The interventions improve compliance with surgical antibiotic prophylaxis and reduce antibiotic utilization and cost. However, there is opportunity for further improvement, particularly in non-elective surgical procedures.

    Ng SF, Jumaat N
    Eur J Pharm Sci, 2014 Jan 23;51:173-9.

    Lyophilised wafers have been shown to have potential as a modern dressing for mucosal wound healing. The wafer absorbs wound exudates and transforms into a gel, thus providing a moist environment which is essential for wound healing. The objective of this study was to develop a carboxymethyl cellulose wafer containing antimicrobials to promote wound healing and treat wound infection. The pre-formulation studies began with four polymers, sodium carboxymethyl cellulose (NaCMC), methylcellulose (MC), sodium alginate and xanthan gum, but only NaCMC and MC were chosen for further investigation. The wafers were characterised by physical assessments, solvent loss, microscopic examination, swelling and hydration properties, drug content uniformity, drug release and efficacy of antimicrobials. Three of the antimicrobials, neomycin trisulphate salt hydrate, sulphacetamide sodium and silver nitrate, were selected as model drugs. Among the formulations, NaCMC wafer containing neomycin trisulphate exhibited the most desirable wound dressing characteristics (i.e., flexibility, sponginess, uniform wafer texture, high content drug uniformity) with the highest in vitro drug release and the greatest inhibition against both Gram positive and Gram negative bacteria. In conclusion, we successfully developed a NaCMC lyophilised wafer containing antimicrobials, and this formulation has potential for use in mucosal wounds infected with bacteria.

    Thalassemia is the commonest hemoglobinopathy in Malaysia. Patients with thalassemia major are transfusion dependent, and a large proportion of them will require splenectomy. As this particular group of patients is immunocompromized, overwhelming sepsis is a recognized complication. We report a series of three patients who all developed intra-abdominal abscesses following splenectomy.

    Rajoo A, Ramanathan S, Mansor SM, Sasidharan S
    J Ethnopharmacol, 2021 Feb 10;266:113414.
    PMID: 32980488 DOI: 10.1016/j.jep.2020.113414
    ETHNOPHARMACOLOGICAL RELEVANCE: Medicinal plants are crucial to healing numerous illnesses. Elaeis guineensis Jacq (family Arecaceae) is a medicinal plant traditionally used for the treatment of wounds.

    AIM OF THE STUDY: However, there are no scientific reports documented on the wound healing activities of this plant against Staphylococcus aureus infections in the Sprague Dawley male rat model. Thus, the present study was conducted to evaluate the wound healing potential of E. guineensis extract leaves.

    MATERIALS AND METHODS: The crude extract was prepared in 10% (w/w) ointment and evaluated for wound healing activity using excision and infected wound models in Sprague Dawley rats. The wound healing activity was evaluated from wound closure rate, CFU reduction, histological analysis of granulation tissue and matrix metalloprotease expression.

    RESULTS: The results show that the E. guineensis extract has potent wound healing ability, as manifest from improved wound closure and tissue regeneration supported by histopathological parameters. Assessment of granulation tissue every fourth day showed a significant reduction in the microbial count. The expression of matrix metalloproteinases was well correlated with the other results, hence confirming E. guineensis wound healing activity's effectiveness.

    CONCLUSIONS: E. guineensis enhanced infected wound healing in rats, thus supporting its traditional use.

  10. Essential oils and metal ions as alternative antimicrobial agents: a focus on tea tree oil and silver
    Low WL, Kenward K, Britland ST, Amin MC, Martin C

    PMID: 27146784 DOI: 10.1111/iwj.12611
    The increasing occurrence of hospital-acquired infections and the emerging problems posed by antibiotic-resistant microbial strains have both contributed to the escalating cost of treatment. The presence of infection at the wound site can potentially stall the healing process at the inflammatory stage, leading to the development of a chronic wound. Traditional wound treatment regimes can no longer cope with the complications posed by antibiotic-resistant strains; hence, there is a need to explore the use of alternative antimicrobial agents. Pre-antibiotic compounds, including heavy metal ions and essential oils, have been re-investigated for their potential use as effective antimicrobial agents. Essential oils have potent antimicrobial, antifungal, antiviral, anti-inflammatory, antioxidant and other beneficial therapeutic properties. Similarly, heavy metal ions have also been used as disinfecting agents because of their broad spectrum activities. Both of these alternative antimicrobials interact with many different intracellular components, thereby resulting in the disruption of vital cell functions and eventually cell death. This review will discuss the application of essential oils and heavy metal ions, particularly tea tree oil and silver ions, as alternative antimicrobial agents for the treatment of chronic, infected wounds.

    Wounds that remain in the inflammatory phase for a prolonged period of time are likely to be colonised and infected by a range of commensal and pathogenic microorganisms. Treatment associated with these types of wounds mainly focuses on controlling infection and providing an optimum environment capable of facilitating re-epithelialisation, thus promoting wound healing. Hydrogels have attracted vast interest as moist wound-responsive dressing materials. In the current study, biosynthetic bacterial cellulose hydrogels synthesised by Gluconacetobacter xylinus and subsequently loaded with silver were characterised and investigated for their antimicrobial activity against two representative wound infecting pathogens, namely S. aureus and P. aeruginosa. Silver nitrate and silver zeolite provided the source of silver and loading parameters were optimised based on experimental findings. The results indicate that both AgNO3 and AgZ loaded biosynthetic hydrogels possess antimicrobial activity (p wound management applications.

    Antimicrobial peptide LL37 is a promising antibacterial candidate due to its potent antimicrobial activity with no known bacterial resistance. However, intrinsically LL37 is susceptible to degradation in wound fluids limits its effectiveness. Bacterial toxins which are released after cell lysis are found to hinder wound healing. To address these challenges, encapsulating LL37 in microspheres (MS) and loading the MS onto activated carbon (AC)-chitosan (CS) hydrogel. This advanced wound dressing not only protects LL37 from degradation but also targets bacterial toxins, aiding in the healing of chronic wound infections. First, LL37 MS and LL37-AC-CS hydrogel were prepared and characterised in terms of physicochemical properties, drug release, and peptide-polymer compatibility. Antibacterial and antibiofilm activity, bacterial toxin elimination, cell migration, and cell cytotoxicity activities were investigated. LL37-AC-CS hydrogel was effective against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. LL37-AC-CS hydrogel bound more endotoxin than AC with CS hydrogel alone. The hydrogel also induced cell migration after 72 h and showed no cytotoxicity towards NHDF after 72 h of treatment. In conclusion, the LL37-AC-CS hydrogel was shown to be a stable, non-toxic advanced wound dressing method with enhanced antimicrobial and antitoxin activity, and it can potentially be applied to chronic wound infections to accelerate wound healing.

    PMID: 26639493
    Microbial resistance to existing antibiotics has led to an increase in the use of medicinal plants that show beneficial effects for various infectious diseases. The study evaluates the susceptibility of multidrug resistant Staphylococcus aureus to Nigella sativa oil. Staphylococcus aureus was isolated from 34 diabetic patient's wounds attending the Renaissance hospital, Nsukka, Southeast Nigeria. The isolates were characterized and identified using standard microbiological techniques. Isolates were cultured and a comparative In vitro antibiotic susceptibility test was carried out using the disk diffusion method. Of the 34 samples collected, 19(56%) showed multidrug resistance to the commonly used antibiotics. Nigella sativa oil was then studied for antibacterial activity against these multidrug resistant isolates of Staphylococcus aureus in varying concentration by well diffusion method. The oil showed pronounced dose dependent antibacterial activity against the isolates. Out of 19 isolates, 8(42%) were sensitive to undiluted oil sample; 4(21%) of these showed sensitivity at 200 mg/ml, 400 mg/ml and 800 mg/ml respectively. Eleven (58%) of the isolates were completely resistant to all the oil concentrations. The present study, reports the isolation of multi-drug resistant S. aureus from diabetic wounds and that more than half of isolates were susceptible to different concentrations N. sativa oil.

  15. Fulltext ZnO-NPs embedded biodegradable thiolated bandage for postoperative surgical site infection: In vitro and in vivo evaluation
    Arshad R, Sohail MF, Sarwar HS, Saeed H, Ali I, Akhtar S, et al.
    PLoS One, 2019;14(6):e0217079.
    PMID: 31170179 DOI: 10.1371/journal.pone.0217079
    Post-operative surgical site infections (SSI) present a serious threat and may lead to complications. Currently available dressings for SSI lack mucoadhesion, safety, efficacy and most importantly patient compliance. We aimed to address these concerns by developing a bioactive thiolated chitosan-alginate bandage embedded with zinc oxide nanoparticles (ZnO-NPs) for localized topical treatment of SSI. The FTIR, XRD, DSC and TGA of bandage confirmed the compatibility of ingredients and modifications made. The porosity, swelling index and lysozyme degradation showed good properties for wound healing and biodegradation. Moreover, in-vitro antibacterial activity showed higher bactericidal effect as compared to ZnO-NPs free bandage. In-vivo wound healing in murine model showed significant improved tissue generation and speedy wound healing as compared to positive and negative controls. Over all, thiolated bandage showed potential as an advanced therapeutic agent for treating surgical site infections, meeting the required features of an ideal surgical dressing.
