Rising antimicrobial resistance is a pressing public health concern. An increase in carbapenem-resistant organisms has led to increased use of novel antibiotics, such as ceftazidime/avibactam (CZ/AV). However, recent studies have shown increasing treatment failures and resistance rates associated with ceftazidime/avibactam use. The efficacy of CZ/AV has not been studied in patients with thermal or inhalation injuries, where pharmacokinetic derangements are common and patients are often subject to longer lengths of stay and several antimicrobial courses that may lead to higher resistance rates. The objective of this study was to evaluate the outcomes of patients with thermal and inhalation injuries including clinical success, the frequency of adverse effects, and emergence of resistance. In the 17 courses of CZ/AV evaluated, clinical success occurred in 71% (12/17) of courses. Enterobacter cloacae was the most commonly treated pathogen. Resistance developed in 18% (3/17) of courses, but follow-up sensitivities were not evaluable for every case. Although lower than desired, clinical success rates in this sample were similar to other reported populations treated with CZ/AV. However, the emergence of resistance occurred more frequently and was likely underreported in this sample. Although limited by its small sample size, this study emphasizes the concern of growing antimicrobial resistance among even novel antibiotics. Resistance can develop during the initial course, stressing the importance of infection prevention and antimicrobial stewardship. Furthermore, attention and resources should be given to proper pharmacokinetic analysis of medications given in severely ill, hypermetabolic populations.
Sarcoidosis rarely involves the genitourinary system or the spinal cord. This report describes a case of sarcoidosis with a scrotal mass, a mass compressing the spinal cord, and lesions in the liver and spleen. This case illustrates an uncommon manifestation of sarcoidosis, which may mimic disseminated testicular cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
