We describe a case of a young male who presented to the emergency department with unilateral eye pain, blurred vision, conjunctival injection, and ocular pH of 9, one day after direct ocular exposure to palytoxin (PTX) from coral in a home saltwater fish tank. Although uncommon, ocular PTX toxicity is a potentially vision-threatening condition that requires prompt recognition. This case report documents the successful management of presumed ocular PTX exposure and suggests additional workup and treatment considerations for future patients.

Elevated intracranial pressure (ICP) is defined as a cerebrospinal fluid (CSF) opening pressure (OP) greater than 25 cmH2O. When a diagnostic lumbar puncture is performed it is useful to estimate also intracranial pressure. To do this it is required a presence of pressure gauges, which are currently the gold standard, not available in most resource-constrained contexts. ⋯ Analysis through ANOVA documented an F of 355.301 with p < 0.01 and Dubin Watson of 1.642. The analysis through ROC showed an AUC of 0.980, with a sensitivity of 100% and a specificity of 91% if chosen as a limit, 29 drops in 30 seconds (Youden Index of 0.9140). Therefore, we have concluded, that although there are several precautions, like patient's position, it is technically feasible to indirectly estimate cerebrospinal fluid pressure with good accuracy by counting the drops of cerebrospinal fluid flowing from a 22 G spinal needle.

Case Reports
Abiotrophia defectiva triple threat: A rare case of infective spondylodiscitis, endocarditis, and brain abscess.
Abiotrophia defectiva is a pathogen of the oral, gastrointestinal, and urinary tracts that can cause significant systemic disease with uniquely negative blood cultures depending on the growth medium. Prior cases note possible seeding from relatively common procedures such as routine dental work and prostate biopsies, however case literature describes prior infectious complications to include infective endocarditis, brain abscess formation, and spondylodiscitis. ⋯ This is the only cases noted in literature with all three infection locations with dual risk factors of dental and prostate procedures prior to symptom onset. This case highlights the multifocal illness that can complicate Abiotrophia defectiva infections, and the importance of thorough ED evaluation and multiservice approach for consultation and treatment.

Nicardipine is commonly used in the management of hypertensive crises, except those involving cardiac contractility defects despite its ability to reduce afterload and pulmonary congestion. Consequently, there is limited literature evaluating nicardipine's role for this indication. The purpose of this study was to evaluate the efficacy and safety of nicardipine in adults with reduced ejection fractions presenting with acute heart failure with hypertension (AHF-H). ⋯ In this non-interventional study evaluating the use of nicardipine in patients with reduced ejection fractions presenting to the ED with AHF-H, nicardipine was found to be safe and effective. To our knowledge this is the largest study to date evaluating nicardipine in this patient population and positively contributes to the existing literature.

Whether a longer no-flow (NF) interval affects the magnitude of response to epinephrine in the resuscitation has not been well studied. Therefore, this study aimed to evaluate the effect of NF interval on the vasopressor effect of initial epinephrine administration in a porcine model. ⋯ In the porcine VF cardiac arrest model, 6 min of NF before resuscitation may affect the vasopressor effect of the initial epinephrine administered compared to 4 min of NF. A short NF may play a role in maximizing the effect of epinephrine in advanced cardiovascular life support.
