Objectives: We sought to determine the frequency at which patients with elevated voriconazole (VRC) levels but no clinically evident central nervous system (CNS) toxicity subsequently develop CNS toxicity., Methods: We retrospectively reviewed the records of adult patients with haematolologic malignancy who had a VRC serum level >5.5 μg/mL at MD Anderson Cancer Center (January 2010 to December 2015). Patients with any documented CNS toxicity at the time the VRC level was obtained or patients whose VRC was discontinued as a response to high VRC level were excluded. Neurologic status was assessed using standard grading scales. Demographic and clinical characteristics, including potentially interacting medications, were correlated with the development of toxicity., Results: We identified 320 such patients (mean age, 57 ± 15 years; 202 male (63%)). Subsequent CNS toxicity was documented in only 16 patients (5%). The most common CNS toxicities were visual disturbances (9/16, 56%), depressed consciousness (5/16, 31%) and cognitive disturbance (4/16, 19%). Patients with CNS toxicity tended to be older than those without (64 ± 8 vs 57 ± 15 y, p 0.08). The use of one or more neurotoxic drugs was common in patients with subsequent CNS toxicity (14/16, 88%). Reduction of VRC dose associated with the high VRC level did not correlate with less subsequent CNS toxicity., Conclusions: Development of subsequent CNS toxicity is uncommon in haematolologic malignancy patients with elevated VRC levels who had no evidence of toxicity at the time the level was obtained. Automatic reduction of VRC dose out of concern for impending CNS toxicity might not be warranted., (Copyright © 2017 European Society of Clinical Microbiology and Infectious Diseases.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne disease caused by a novel bunyavirus. Although the increasing numbers of cases and deaths is of great concern, an effective treatment strategy for SFTS has not been established. We present the cases of two patients with rapidly progressing SFTS who were successfully treated with plasma exchange and ribavirin., (Copyright © 2013 The Authors. Published by Elsevier Ltd..

Forty-two multidrug-resistant (MDR) Acinetobacter baumannii isolates were obtained during outbreaks in a Korean hospital. The co-carriage of bla(OXA-23), bla(OXA-51), bla(PER-1) and armA was observed in 23 isolates, and they were susceptible only to colistin and minocycline. The MDR A. baumannii isolates were found to belong to sequence group 1 using sequence-based typing.
