    Abstract This case presents a patient with ectopic secretion of adrenocorticotrophic hormone from a carcinoid tumor resulting in severe hypertension, posterior reversible encephalopathy syndrome (PRES), and refractory status epilepticus. Secondary hypertension may be difficult to identify in critically ill patients. Severely uncontrolled hypertension presenting with PRES caused by Cushing syndrome is rare but should be considered. Management requires the correct diagnosis and specific treatment. A missed or delayed diagnosis can lead to serious consequences and disability.

    Abstract Intracerebral hemorrhage (ICH) is a stroke subtype with high mortality and significant disability among survivors. The management of ICH has been influenced by the results of several major trials completed in the last decade. It is now recognized that hematoma expansion is a major cause of morbidity and mortality. However, efforts to improve clinical outcome through mitigation of hematoma expansion have so far been unsuccessful. Acute blood pressure management has recently been shown to be safe in the setting of acute ICH but there was no reduction in mortality with early blood pressure (BP) lowering. Two large trials of surgical evacuation of supratentorial ICH have not shown improvement in outcome with surgery, thus minimally invasive surgical strategies are currently being studied. Lastly, a better understanding of the pathophysiology of ICH has led to the identification of several new mechanisms of injury that could be potential therapeutic targets.

    Abstract Objectives: The purpose of this pilot study was to obtain baseline quantitative pupillometry (QP) measurements before and after catheter-directed cerebral angiography (DCA) to explore the hypothesis that cerebral angiography is an independent predictor of change in pupillary light reflex (PLR) metrics.
    Design: This was a prospective, observational pilot study of PLR assessments obtained using QP 30 min before and after DCA. All patients had QP measurements performed with the NPi-300 (Neuroptics) pupillometer.
    Setting: Recruitment was done at a single-centre, tertiary-care academic hospital and comprehensive stroke centre in Dallas, Texas.
    Participants: Fifty participants were recruited undergoing elective or emergent angiography. Inclusion criteria were a physician-ordered interventional neuroradiological procedure, at least 18 years of age, no contraindications to PLR assessment with QP, and nursing transport to and from DCA. Patients with a history of eye surgery were excluded.
    Main outcome measures: Difference in PLR metric obtained from QP 30 min before and after DCA.
    Results: Statistically significant difference was noted in the pre and post left eye readings for the minimum pupil size (a.k.a., pupil diameter on maximum constriction). The mean maximum constriction diameter prior to angiogram of 3.2 (1.1) mm was statistically larger than after angiogram (2.9 (1.0) mm; p<0.05); however, this was not considered clinically significant. Comparisons for all other PLR metrics pre and post angiogram demonstrated no significant difference. Using change in NPi pre and post angiogram (Δpre=0.05 (0.77) vs Δpost=0.08 (0.67); p=0.62), we calculated the effect size as 0.042. Hence, detecting a statistically significant difference in NPi, if a difference exists, would require a sample size of ~6000 patients.
    Conclusions: Our study provides supportive data that in an uncomplicated angiogram, even with intervention, there is no effect on the PLR.

    Abstract Purpose of review: The purpose of this review is to examine the impact of pupillometer assessment on care and research of patients with neurological injury.
    Recent findings: Recent studies demonstrate that automated pupillometry outperforms manual penlight pupil examination in neurocritical care populations. Further research has identified specific changes in the pupillary light reflex associated with pathologic conditions, and pupillometry has been used to successfully identify early changes in neurologic function, intracranial pressure, treatment response to osmotherapy, and prognosis after cardiac arrest. Automated pupillometry is being increasingly adopted as a routine part of the neurologic examination, supported by a growing body of literature demonstrating its reliability, accuracy, and ease of use. Automated pupillometry allows rapid, non-invasive, reliable, and quantifiable assessment of pupillary function which may allow rapid diagnosis of intracranial pathology that affects clinical decision making.

    Abstract Abstract: INTRODUCTION: Enteral nimodipine provides a neuroprotective effect in patients who have experienced an aneurysmal subarachnoid hemorrhage (aSAH). Nimodipine remains the only US Food and Drug Administration-approved medication for aSAH. CONTENT: Nimodipine has been prescribed for patients with aSAH; however, little is known about factors to consider regarding dosing or patient-specific variables that may affect tolerability to nimodipine. Clinical impact of dose or dosing frequency changes has also been much debated based on risk of hypotension with currently approved dosing regimens. CONCLUSION: This review article addresses factors to consider for dosing and administration, pharmacokinetic and pharmacogenetic impact on nimodipine, and, finally, drug interaction considerations to assess as patients are initiated on enteral nimodipine for aSAH.
