Objective: The objective of this review is to describe the outcomes of patients treated with ceftaroline in the non-Food and Drug Administration (FDA) approved indication of methicillin-resistant Staphylococcus aureus (MRSA) infections in both pediatric and adult populations. Data sources: A systematic overview was conducted by searching PubMed, Medline, and The Cochrane Library up to January 2019. Study selection and data extraction: All English-language clinical trials and case reports related to the efficacy of ceftaroline in new, not-yet-approved FDA indications in MRSA infections in pediatric or adult populations. Data synthesis: In the case of MRSA bacteremia (MRSAB) infections, three different randomized studies in pediatric patients showed effectiveness of ceftaroline. When used in the case of adult populations with MRSA bacteremia, a small trial of 16 patients showed 50% clinical success in patients with acute bacterial skin and skin structure infections versus 63% clinical success in patients with community-acquired bacterial pneumonia. Another case series of six refractory case reports showed 50% clinical success of ceftaroline in patients with MRSA. Conclusions: Although there are few case reports and limited data to date, ceftaroline fosamil should continue to be studied as an alternative therapy in MRSA infections in both pediatric and adult populations. Clinical success rates of ceftaroline were, in most cases, considered high when treating patients with MRSA infection. More clinical trials need to be studied. In the specific case of MRSA bacteremia, the treatment options remain few and ceftaroline should be extensively studied for the salvage treatment of MRSAB.

The role of circumcision and its benefits has received increased attention across several disciplines in recent years; however, there is increasing concern that some uncommon complications such as severe infections are being related to post-circumcision. We describe the clinical course of a 14-day-old boy who had Methicillin-resistant Staphylococcus aureus urosepsis after circumcision.

Abstract Ceftaroline is approved by the Food and Drug Administration for acute bacterial skin and skin-structure infections and community-acquired bacterial pneumonia, including cases with concurrent bacteremia. Use for serious methicillin-resistant Staphylococcus aureus (MRSA) infections has risen for a multitude of reasons. The aim of this article is to review the literature evaluating clinical outcomes and safety of ceftaroline prescribed for serious MRSA infections. We conducted a literature search in Ovid (Medline) and PubMed for reputable case reports, clinical trials, and reviews focusing on the use of ceftaroline for treatment of MRSA infections. Twenty-two manuscripts published between 2010 and 2016 met inclusion criteria. Mean clinical cure was 74% across 379 patients treated with ceftaroline for severe MRSA infections. Toxicities were infrequent. Ceftaroline treatment resulted in clinical and microbiologic cure for severe MRSA infections. Close monitoring of hematological parameters is necessary with prolonged courses of ceftaroline.

Background: Evidence supporting beta-lactam plus vancomycin synergy for methicillin-resistant Staphylococcus aureus (MRSA) continues to grow. Current in vivo evidence demonstrates that combination therapy is associated with shorter time to blood sterilization than vancomycin monotherapy. However, this combination has not been reported as salvage therapy for persistent MRSA bacteremia. Case report: We report a case of an 81-year-old male who was successfully treated with vancomycin plus nafcillin after failing vancomycin monotherapy, daptomycin monotherapy, and daptomycin plus gentamicin combination therapy. The patient originally presented with sepsis from a suspected urinary tract infection. Blood cultures drawn on days 1, 3, 5, 15, 19, 23, and 28 remained positive for MRSA despite multiple antimicrobial therapy changes. On day 29, therapy was changed to vancomycin plus nafcillin. Blood cultures drawn on day 32 remained negative. After 11 days, nafcillin was changed to piperacillin–tazobactam due to an infected decubitus ulcer. The combination was continued for 42 days after achieving blood sterility, 71 days after the patient originally presented. Evidence regarding salvage therapy for persistent bacteremia is sparse and is limited to case reports and case series. Conclusion: This case report supports that vancomycin plus an anti-staphylococcal beta-lactam combination should be further studied as salvage therapy for persistent MRSA bacteremia.

INTRODUCTION Marker pens are widely used in surgery but pre-operative marking of patients may be a cause of bacterial cross-infection. PATIENTS AND METHODS Two experiments were performed to assess whether marking pens can be cause of cross-infection: (i) 26 indelible marker pens were collected from surgical wards for analysis; and (ii) ‘fresh’ as well as ‘dry’ (artificially dried by removing cap and exposing tip for 2 h) new permanent marker pens, and whiteboard marker pens were inoculated by dipping the tips into various concentrations of methicillin-resistant Staphylococcus aureus (MRSA). Each pen was inoculated onto 2 blood agar plates at 0 (immediately after inoculation) to 30 min at various intervals, 4 h and 24 h. The plates were incubated for 18 h at 35°C in an incubator. RESULTS Of 26 pens collected from the wards, 2 cultured Micrococci spp. (skin commensals). The constituents of new ‘fresh’ pen tips rapidly kill MRSA – in all cases by 4 h, but usually within minutes. At high inoculum concentrations, MRSA is not killed immediately. Dry marker pens harbour MRSA for at least 30 min and probably longer. CONCLUSIONS Marker pens can act as fomites for nosocomial infection. The ethanol-based ink in permanent marker pens has a bactericidal action against MRSA that starts within seconds, and they are likely to be safe to use with a gap of at least 2 min between patients. Usually, harmless skin commensals are not pathogenic except in immunocompromised patients. Old or dried-out marker pens can harbour pathogens and should be discarded before attempted use on patients. We recommend disposable markers for the immunocompromised and patients with a known positive MRSA status.
