Background: Glucocorticoids are the main drug used to control vasogenic edema in patients with brain tumor. Rapid GC tapering may not only decompensate intracranial pressure, but also unmask SAI, and some symptoms of SAI can be mistakenly attributable to increased intracranial pressure or side effects of chemotherapy and radiation therapy.
Methods: The University of Virginia Neuro-Oncology Database was reviewed from February 2002 to January 2006, and 5 neuro-oncology patients with clinical and laboratory evidence of SAI were identified.
Results: In our experience, 1% of neuro-oncology patients treated with GC developed SAI. Symptoms resembled increased intracranial pressure or side effects of antineoplastic treatment.
Conclusion: A healthy index of suspicion for this complication and use of pharmacologic testing will help avert misattribution of symptoms of SAI and its deleterious consequences.

Health Economics, Hospital Management and Nursing Research Deptment, School of Public Health, Université Libre de Bruxelles - Bruxelles, Belgium.
Objective: This study aimed to explore the association between high outliers and intensive care unit admissions and to identify the factors contributing to high intensive care unit costs.
Methods: This retrospective cohort study used data from 17 Belgian hospitals from 2018 and 2019. The study focused on the 10 most frequently admitted diagnosis-related groups in the intensive care unit.
Effects of intrathecal administration of sodium nitroprusside and nicardipine on cerebral pial microcirculation, cortical tissue oxygenation, and electrocortical activity in the early post-resuscitation period in a porcine cardiac arrest model.

Recent studies suggested intrathecal vasodilator administration as a therapy to mitigate post-ischemic cerebral hypoperfusion following cardiac arrest. We examined the effects of two commonly used intrathecal vasodilators, sodium nitroprusside (SNP) and nicardipine, on cerebral pial microcirculation, cortical tissue oxygen tension (PctO2), and electrocortical activity in the early post-resuscitation period using a porcine model of cardiac arrest. Thirty pigs were resuscitated after 14 min of untreated cardiac arrest.

Netter Medical School (JGJ-C), North Haven, Connecticut; and Department of Anesthesiology (DZ), Critical Care and Pain Medicine, Boston Children's Hospital, Harvard Medical School, Boston, Massachusetts.
Background: Patients with craniosynostosis are at high risk of developing elevated intracranial pressure (ICP) causing papilledema and secondary optic atrophy. Diagnosing and monitoring optic neuropathy is challenging because of multiple causes of vision loss including exposure keratopathy, amblyopia, and cognitive delays that limit examination. Peripapillary hyperreflective ovoid mass-like structures (PHOMS) are an optical coherence tomography (OCT) finding reported in association with papilledema and optic neuropathy.

Purpose Of Review: This review explores the phenomenology, pathogenesis, and nosology of headaches associated with infections, an often-overlooked yet clinically significant symptom. With the increasing recognition of secondary headaches in infections, understanding their clinical patterns, mechanisms, and classifications is crucial for accurate diagnosis and management.
Recent Findings: Headaches in infections are ubiquitous but vary in presentation, severity, and underlying mechanisms depending on the causative pathogen.
Unicoronal synostosis is a rare condition leading to anterior plagiocephaly with facial scoliosis and deformation of the anterior cranial fossa. Fronto-orbital advancement and remodelling (FOAR) is the standard of care for management, aiming to normalise the brow shape and position while ameliorating the risk of raised intracranial pressure (ICP) throughout childhood. Published long-term surgical outcome data for unicoronal synostosis is lacking.
