Metronidazole is a nitroimidazole antimicrobial drug prescribed to treat infections caused by anaerobic bacteria and protozoa. Uncommonly, it causes central nervous system (CNS) toxicity manifesting as metronidazole-induced encephalopathy (MIE). ⋯ MIE is an uncommon adverse effect of treatment with metronidazole that characteristically affects the dentate nuclei but may also involve the brainstem, corpus callosum, subcortical white matter, and basal ganglia. While the clinical symptoms and neuroimaging changes are usually reversible, persistent encephalopathy with poor outcome may occur.

Headache after aneurysmal subarachnoid hemorrhage (SAH) is very common and is often described as the "worst headache imaginable." SAH-associated headache can persist for days to weeks and is traditionally treated with narcotics. However, narcotics can have significant adverse effects. We hypothesize that gabapentin (GBP), a non-narcotic neuropathic pain medication, would be safe and tolerable and would reduce narcotic requirements after SAH. ⋯ GBP appears to be relatively safe and tolerable in SAH patients with headache and may be a useful narcotic-sparing agent to prevent narcotics-associated complications, such as gastrointestinal immobility, ileus, and constipation.

Feasibility and Diagnostic Accuracy of Early Electrophysiological Recordings for ICU-Acquired Weakness: An Observational Cohort Study.
An early diagnosis of ICU-acquired weakness (ICU-AW) is difficult because disorders of consciousness frequently preclude muscle strength assessment. In this study, we investigated feasibility and accuracy of electrophysiological recordings to diagnose ICU-AW early in non-awake critically ill patients. ⋯ Nerve conduction studies of the ulnar and peroneal nerve are feasible in critically ill patients. The diagnostic accuracy is low using cut-off values from healthy controls. Cut-off values validated specifically for discrimination between critically ill patients with and without ICU-AW may improve diagnostic accuracy.

Long-term studies of survivors of acute respiratory distress syndrome (ARDS) have reported neuromuscular, quality of life, and neuropsychological impairments. This study aims to determine if development of ARDS was associated with neuromuscular weakness and depression at 6-month following hospital discharge in a population-based cohort of patients at high risk for ARDS. ⋯ In this single-center population-based cohort study, survivors of ARDS in the community had similar reported functional impairment and depression prevalence compared to an at-risk cohort that did not develop ARDS.
