Orolabial Lymphogranuloma Venereum, Michigan, USA.

Orolabial lymphogranuloma venereum was diagnosed for a man in Michigan, USA, who had sex with men, some infected with HIV. High index of suspicion for lymphogranuloma venereum led to accurate diagnosis, successful therapy, and description of an L2b variant with a unique genetic mutation.

Correlation between Identification of ß-Lactamase Resistance Genes and Antimicrobial Susceptibility Profiles in Gram-Negative Bacteria: a Laboratory Data Analysis.

We reported the frequency of resistance gene detection in Gram-negative blood culture isolates and correlated these findings with corresponding antibiograms. Data were obtained from 1045 isolates tested on the GenMark Dx ePlex Blood Culture Identification Gram-Negative Panels at the Mount Sinai Hospital Clinical Microbiology Laboratory in New York from March 2019 to February 2021. Susceptibilities were performed using Vitek 2 (bioMérieux Clinical Diagnostics) or Microscan (Beckman Coulter Inc.). blaCTX-M was detected in 26.4% Klebsiella pneumoniae, 23.5% Escherichia coli, and 16.4% Proteus mirabilis isolates. As would be expected, both blaCTX-M and blaCTX-M negative isolates were likely to be susceptible to newer agents while blaCTX-M positive isolates were more likely to be resistant to earlier generations of beta-lactam antibiotics. 3/204 blaCTX-M-positive isolates were found to be ceftriaxone-susceptible. Conversely, 2.8% ceftriaxone nonsusceptible strains were negative for all ß-lactamase genes on the ePlex BCID-GN panel, including blaCTX-M. The prevalence of CTX-M-producing Enterobacterales remains high in the United States. A small number of blaCTX-M-positive isolates were susceptible to ceftriaxone, and a small number of ceftriaxone nonsusceptible isolates were negative for blaCTX-M. Further studies are needed to determine the optimal management when an isolate is phenotypically susceptible to ceftriaxone, but blaCTX-M is detected. IMPORTANCE There is limited literature on corresponding results obtained from rapid molecular diagnostics with the antibiotic susceptibility profile. We reported a correlation between the results obtained from ePlex and the antibiograms against a large collection of Gram-negative bacteria. We reported that there can be a discrepancy in a small number of cases, but the clinical significance of that is unknown.

Preventing Varicella-Zoster: Advances With the Recombinant Zoster Vaccine.

Prevention strategies against varicella zoster infection include chemoprophylaxis with acyclovir and live attenuated zoster vaccine. However, resistance to acyclovir has been problematic, and safety concerns have limited the use of the live attenuated vaccine in immunosuppressed patients. Recombinant zoster vaccine, made available in 2017 for the immunocompetent host, has been evaluated for safety, immunogenicity, and efficacy in several immunocompromised settings as well. The present review compares the live attenuated vaccine and the recombinant zoster vaccine and highlights data on the use of recombinant zoster vaccine in different immunocompromised states. Robust data are available for the safety, immunogenicity, and efficacy of the recombinant vaccine in the autologous stem cell population, particularly among patients with multiple myeloma. The vaccine appears safe and immunogenic in populations including those with cancer (solid tumors and hematologic malignancies), HIV-infected patients, and renal transplant recipients. Efficacy and safety data in other populations are awaited before use of the recombinant vaccine can be more widespread. It is anticipated that an increased use of the recombinant zoster vaccine, particularly in immunosuppressed patients, would lead to a decreased use of acyclovir prophylaxis.

Outcomes of an Online Virtual Boot Camp to Prepare Fourth-Year Medical Students for a Successful Transition to Internship.

Introduction Changes in medical education and health care delivery have limited the ability of fourth-year medical students to perform the role of an intern prior to graduating from medical school. To address this issue, many schools have instituted residency preparation courses (sometimes referred to as boot camps) particularly for students entering surgical fields. Courses for students entering nonprocedural fields are less common and most assess increases in self-reported confidence without providing objective evidence of a gain in knowledge or skills improvement. Materials and Methods We used a Plan, Do, Study, Act (PDSA) model to develop and pilot cycle 1 of a nonprocedural internship preparation elective in 2019. Feedback was used to refine the course and map sessions to core competencies outlined by the Accreditation Council of Graduate Medical Education (ACGME) for PDSA cycle 2. The curriculum was adapted for remote synchronous delivery due to the coronavirus pandemic in spring 2020 using a combination of didactic lectures containing embedded polls and case-based role play responses using a chat box. Students completed anonymous surveys assessing self-perceived levels of confidence, as well as an objective comprehensive assessment after course completion. Results A total of 89 students participated in the course. Pre-session confidence was lowest for transfusion medicine, handling pages from nursing while on call, and knowledge of the role of a chief resident. A statistically significant increase in median scores for self-reported knowledge or confidence was seen in all sessions. The percentage of students reporting that they were either confident or extremely confident also increased significantly after each session (p<0.001 for all). All sessions analyzed were rated as useful or extremely useful by more than half of the students, and 94% of the students scored 70% or higher on the comprehensive course assessment. Conclusions An online virtual synchronous boot camp increased students' confidence in handling common topics encountered during residency and demonstrated an appropriate gain in knowledge using a comprehensive assessment. We were able to adapt our curriculum to a remote model and will likely keep several sessions in an online format in the future.
