Abstract

Background: In Japan, carbapenem-resistant Enterobacterales (CRE) infections were incorporated into the National Epidemiological Surveillance of Infectious Diseases (NESID) in 2014, necessitating mandatory reporting of all CRE infections cases. Subsequently, pathogen surveillance was initiated in 2017, which involved the collection and analysis of CRE isolates from reported cases to assess carbapenemase gene possession. In this surveillance, CRE is defined as (i) minimum inhibitory concentration (MIC) of meropenem ≥2 mg/L (MEPM criteria) or (ii) MIC of imipenem ≥2 mg/L and MIC of cefmetazole ≥64 mg/L (IPM criteria). This study examined whether the current definition of CRE surveillance captures cases with a clinical and public health burden. Methods: CRE isolates from reported cases were collected from the public health laboratories of local governments, which are responsible for pathogen surveillance. Antimicrobial susceptibility tests were conducted on these isolates to assess compliance with the NESID CRE definition. The NESID data between April 2017 and March 2018 were obtained and analyzed using antimicrobial susceptibility test results. Results: In total, 1681 CRE cases were identified during the study period, and pathogen surveillance data were available for 740 (44.0%) cases. Klebsiella aerogenes and Enterobacter cloacae complex were the dominant species, followed by Klebsiella pneumoniae and Escherichia coli. The rate of carbapenemase gene positivity was 26.5% (196/740), and 93.4% (183/196) of these isolates were of the IMP type. Meanwhile, 315 isolates were subjected to antimicrobial susceptibility testing. Among them, 169 (53.7%) fulfilled only the IPM criteria (IPM criteria-only group) which were susceptible to meropenem, while 146 (46.3%) fulfilled the MEPM criteria (MEPM criteria group). The IPM criteria-only group and MEPM criteria group significantly differed in terms of carbapenemase gene positivity (0% vs. 67.8%), multidrug resistance rates (1.2% vs. 65.8%), and mortality rates (1.8% vs 6.9%). Conclusion: The identification of CRE cases based solely on imipenem resistance has had a limited impact on clinical management. Emphasizing resistance to meropenem is crucial in defining CRE, which pose both clinical and public health burden. This emphasis will enable the efficient allocation of limited health and public health resources and preservation of newly developed antimicrobials. [ABSTRACT FROM AUTHOR]

34. Two Cases of Penoscrotal Strangulation

Author

Subjects
Penile strangulation, Penoscrotal strangulation, 494.9
Abstract

Case 1 (42-year-old man) : The patient was examined for penoscrotal swelling that had continued for 1 month. An annular erosive skin ulcer was observed at the penoscrotal base, with distal swelling. Asking the patient about the history of his condition was difficult due to a history of mental illness. We suspected his symptoms were due to an embedded foreign object. As computed tomography indicated the presence of a subcutaneous foreign object, surgery was performed to remove it. A rubber band was found wrapped twice around the area. After releasing the strangulation, penoscrotal swelling improved. Case 2 (72-year-old man) : Penoscrotal swelling appeared after having an automobile tow hook attached to the penoscrotal base for 2 weeks. The patient was examined at the emergency room because he could not remove it on his own. A rescue squad was called, and they cut the strangulating object with an electric saw. After releasing the strangulation, penoscrotal swelling improved. Although we experienced 2 cases of penoscrotal strangulation involving strangulating objects with different characteristics, improvement was achieved in both by releasing the strangulation. The cases of penoscrotal strangulation reported in Japan with known strangulation type are reviewed.
