A 69-year-old woman without significant medical history presented to an emergency department for evaluation and management of altered mental status and a 10-day history of worsening symptoms of upper respiratory infection. Two days previously, she had been evaluated at an urgent care center, where she reported productive cough and neck pain. Evaluation in the emergency department aroused suspicions of sepsis and meningitis, and computed tomography of the head revealed nontraumatic pneumocephalus with evidence of bony erosion of the sinus into the brain. Culture results revealed disseminated Streptococcus pneumoniae. Cerebral vasculopathy secondary to the meningitis caused bilateral acute ischemic strokes in areas of the brain, with the potential to lead to significant disability.

Prolonged bed rest is a known contributor to muscle atrophy, weakness, and deconditioning. Early active mobilization protocols aim to combat acquired weakness and loss of function in patients in the intensive care unit. Despite these benefits, mobilization of patients in the intensive care unit remains a challenge, most notably for patients with limited ability to get out of bed because of invasive devices and prolonged hospitalization. Virtual reality has gained favor for use in critical care to mitigate patients' stress, pain, and anxiety and to provide distraction and socialization. This case report demonstrates a novel application of virtual reality and the ease with which virtual reality can be used to facilitate early mobility and activity progression in the critically ill.

The experience of serious illness or injury frequently results in increased vulnerability. In cases in which decision-making capacity is compromised, this vulnerability is compounded by threats to a patient's autonomy. This case report presents an opportunity to explore the elaborately entwined relationship between autonomy and vulnerability in patients with severe impairment who are reliant on surrogate decision-makers. Expanded views of autonomy and vulnerability are applied to the case of a young woman with a severe and life-altering spinal cord injury and iatrogenic loss of decisional capacity to illustrate how one can experience enhanced autonomy despite special vulnerability and can be made less vulnerable through surrogate-mediated autonomy. Also revealed is how attitudes and actions of surrogates can potentiate pathogenic vulnerability and disturb the balance between patient autonomy and vulnerability. Through methodical review and robust deliberation, clinical ethics committees can play a stabilizing role in helping distressed care teams reconcile the two.

β-Adrenergic agonist medications such as albuterol are the mainstay for treatment of patients with acute asthma exacerbations. Patients who present to the emergency department with severe symptoms are often treated with multiple albuterol doses in sequence to maximize the impact of the medications, relax bronchoconstriction, and relieve their breathlessness. Patients who present with acute dyspnea have numerous potential causes of hyperlactatemia and acidosis including an uncommonly recognized outcome of albuterol administration. This clinical case report outlines a scenario where a patient who was treated for an acute asthma exacerbation had rising lactate levels despite improving clinically. Causes of elevated lactate levels are discussed, particularly related to β-adrenergic agonist use, and considerations for monitoring and withdrawal of albuterol administration are outlined.
