A commonly cited reason for the infrequent detection of cognitive impairment in the Emergency Department (ED) is the lack of an appropriate screening tool. The Abbreviated Mental Test 4 (AMT4) is a brief instrument recommended for cognitive screening of older adults in the ED. However, its exact utility in the detection of altered mental status in the ED is yet to be fully determined. ⋯ The present study found that the limited sensitivity of the AMT4 in identifying the majority of cognitively impaired persons restricts its use in isolation as a general cognitive screener in the ED.

Extracorporeal membrane oxygenation (ECMO) is a life-saving system used for critically ill patients with cardiac and/or respiratory failure. The pharmacokinetics (PK) of drugs can change in patients undergoing ECMO, which can result in therapeutic failure or drug toxicity requiring further management of drug complications. In this review, we discussed changes in the PK of antibiotic, antiviral, antituberculosis and antifungal agents administered to adult patients on ECMO. These drugs are crucial for managing infections, which commonly occur during ECMO. ⋯ The impact of ECMO on PK varies among drugs in adult patients, and there is no consistent correlation between the effects observed in adult and infant studies. This review suggested that doses of imipenem, oseltamivir, rifampicin and voriconazole should be adjusted and therapeutic drug monitoring is needed when ECMO is used in adult patients. In the future, large PK trials in adults on ECMO are needed to provide optimal dosing guidelines. A PK/PD modelling approach will be useful for determining the precise impact of ECMO and other factors that contribute to PK changes for each drug. Finally, it is important to develop dosing guidelines based on PK/PD modelling studies that can be used in clinical practice.

Case ReportsClinical manifestations and treatment outcomes of parvovirus B19 encephalitis in immunocompetent adults.
Parvovirus B19 (PVB19) has rarely been identified as a cause of encephalitis in immunocompetent adults, in whom clinical information regarding PVB19 encephalitis has remained unclear. Herein, we report the clinical presentations, laboratory and imaging findings, and treatment outcomes of five immunocompetent adults with PVB19 encephalitis. Although none of the patients showed any distinctive features of PVB19 infection, they showed various clinical manifestations, including one instance of brainstem involvement. Additionally, immunotherapy can be considered an effective approach, especially in immunocompetent adults with PVB19 encephalitis who are resistant to the initial management.

Stereotactic radiosurgery (SRS) is a well-established treatment modality for cerebral arteriovenous malformations (AVMs). The main limiting factor in the radiosurgical treatment of AVMs is the volume of the nidus, with high-grade lesions often requiring combined treatment to reduce the SRS target volume. To overcome this limitation, we have been using a combined treatment approach consisting of endovascular embolization with Onyx followed by SRS. ⋯ The multimodality treatment of cerebral AVMs using embolization with Onyx followed by SRS is feasible and safe. The use of Onyx significantly reduced the SRS treatment target volume.
