    Abstract Background: During the first wave of the COVID-19 pandemic, a substantial number of Quebec hospitals were hit by hospital-acquired (HA) SARS-CoV-2 infections. Our objective was to assess whether mortality is higher in HA cases than in non-hospital-acquired (NHA) cases and determine the prevalence of HA-SARS-CoV-2 infection in our hospital.
    Methods: This retrospective single-centre cohort study included all adults (≥ 18 yr) who had COVID-19, admitted to Hôpital Maisonneuve-Rosemont (Montréal, Canada) from Mar. 1 to June 30, 2020. We collected data on demographic characteristics, comorbidities, treatment, admission to the intensive care unit (ICU) and mechanical ventilation requirements from electronic health records. We adjudicated hospital acquisition based on the timing of symptom onset, and polymerase chain reaction testing for and exposures to SARS-CoV-2. To evaluate the association between HA-SARS-CoV-2 infection and in-hospital mortality, we computed a multivariable logistic regression analysis including known risk factors for death in patients with COVID-19 as covariates.
    Results: Among 697 patients with SARS-CoV-2 infection, 253 (36.3%) were classified as HA. The mortality rate was higher in the HA group than in the NHA group (38.2% v. 26.4%,
    Interpretation: Our results show that HA-SARS-CoV-2 infection in younger patients was associated with higher mortality. Future studies need to evaluate relevant patient-centred long-term outcomes in this population.

    Abstract Background: Burkholderia stabilis
    Methods: One sample was not available for testing, but the remaining 10 isolates (91%) were sent for phylogenetic testing. Medical materials and the patients' environments were also sampled and cultured. Samples were tested using pulsed field gel electrophoresis and multilocus sequence typing.
    Results: The outbreak was found to be associated with the use of intrinsically contaminated non-sterile ultrasound gel. Relatedness of the gel's and the patients'
    Conclusion: Contaminated non-sterile gel caused infections and pseudo-infections in several patients.

    Abstract A 40-year-old man reported a 5-day history of fever and malaise, followed by a pruritic generalized rash. He had well-demarcated erythematous papules and plaques with scaling. The patient was diagnosed with secondary syphilis. The skin biopsy showed a psoriasiform lichenoid dermatitis with plasma cells. The anti-T. pallidum antibody confirmed the presence of spirochetes. He was also found to be hepatitis C virus and human immunodeficiency virus positive. The characteristic rash of secondary syphilis may appear as maculopapular, evolving initially from macules to small reddish-brown papules with minor scaling later. When the scaling is prominent, lesions can be difficult to differentiate from guttate psoriasis. Typical target lesions are most often associated with erythema multiforme, but they can rarely occur in secondary and congenital syphilis. Syphilis should be suspected in high-risk patients presenting a variety of atypical syndromes such as neurologic symptoms, uveitis or cholestatic hepatitis, especially if palmoplantar lesions are present.

    Abstract From March 2014 to December 2016, a cluster of 13 cases of Campylobacter fetus intestinal and extraintestinal infections, including 2 patients with an aortic mycotic aneurysm, caused significant morbidity. The cluster likely resulted from sexual transmission between men having sex with men living in the greater Montreal area, Quebec, Canada.

    Abstract In this controlled before-after study, wound swabs were only processed for culture, identification, and susceptibility testing if a quality metric, determined by the Q score, was met. Rejection of low-quality wound swabs resulted in a modest decrease in reflexive antibiotic initiation while reducing laboratory workload and generating few clinician requests.
