BACKGROUNDThe management of nonmissile penetrating head injuries is not well established given the heterogeneity of injuries described. The authors describe the management of a patient who presented to their institution along with a review of the literatureOBSERVATIONSThe glass shard was removed in the operating room with the ophthalmology team without complication. A diagnostic cerebral angiogram was also obtained in an urgent and delayed fashion. A total of 53 studies with 90 patients were included. The mean age was 27 years, and 86% of subjects were male. The frontal region violated via metal spike was the most common location of injury. Prophylactic antibiotics and antiepileptic drugs were administered in 68% and 24%, respectively. Craniotomy for removal was performed in 82% of cases and infection occurred in 6%.LESSONSEmergency CT angiography should be obtained when concern for vascular injury based on trajectory or significant depth of penetration exists. Immediate administration of prophylactic antibiotics and AEDs should be completed. Diagnostic angiography for suspicion of vessel injury in an urgent and delayed fashion should be performed. Removal of intracranial objects should only occur in the operating room. Immediate postoperative CT should be utilized to rule out worsening of intracranial injury.https://thejns.org/doi/10.3171/CASE24851

Mitral valve prolapse is a common valve disorder that usually has a benign prognosis unless there is significant regurgitation or LV impairment. However, a subset of patients are at an increased risk of ventricular arrhythmias and sudden cardiac death, which has led to the recognition of "arrhythmic mitral valve prolapse" as a clinical entity. Emerging risk factors include mitral annular disjunction and myocardial fibrosis. While echocardiography remains the primary method of evaluation, cardiac magnetic resonance has become crucial in managing this condition. Cine magnetic resonance sequences provide accurate characterization of prolapse and annular disjunction, assessment of ventricular volumes and function, identification of early dysfunction and remodeling, and quantitative assessment of mitral regurgitation when integrated with flow imaging. However, the unique strength of magnetic resonance lies in its ability to identify tissue changes. T1 mapping sequences identify diffuse fibrosis, in turn related to early ventricular dysfunction and remodeling. Late gadolinium enhancement sequences detect replacement fibrosis, an independent risk factor for ventricular arrhythmias and sudden cardiac death. There are consensus documents and reviews on the use of cardiac magnetic resonance specifically in arrhythmic mitral valve prolapse. However, in this article, we propose an algorithm for the broader use of cardiac magnetic resonance in managing this condition in various scenarios. Future advancements may involve implementing techniques for tissue characterization and flow analysis, such as 4D flow imaging, to identify patients with ventricular dysfunction and remodeling, increased arrhythmic risk, and more accurate grading of mitral regurgitation, ultimately benefiting patient selection for surgical therapy.

The COVID-19 pandemic with the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has been one of the largest topics of discussion in the medical world over the last few years. Most of the research has focused on the risks and correlation of chronic diseases and immunosuppression with the severity and mortality of the viral infection. Less research has occurred in the setting of post-infectious sequelae and the long-term effects of COVID-19 with the development of chronic conditions and diseases, such as new-onset type 1 diabetes mellitus. The incidence of diabetic ketoacidosis (DKA) has increased during the COVID-19 pandemic, but the relationship between the two conditions remains to be fully understood. We report the case of a 24-year-old male who presents with malaise, polyuria, polydipsia, headache, and fatigueand was eventually found to be in diabetic ketoacidosis (DKA). He had a history of COVID-19 infection 12 weeks prior to this presentation. He also had a family history of DKA and type 1 diabetes mellitus. This case highlights the need to perform an in-depth workup for each patient with DKA and new-onset diabetes mellitus in order to find a potential cause of the autoimmune condition.

This review sought to define the mechanism of the drug-drug interaction between phosphodiesterase-type-5 (PDE-5) inhibitors and organic nitrates as well as the clinical impact and recommended management across different clinical scenarios. This drug-drug interaction results in hemodynamically significant hypotension during episodic PDE-5 use and acute nitrate administration mainly during cardiovascular emergencies with multiple studies describing the expected impact. Chronic co-administration of long-acting nitrates and PDE-5 inhibitors has been observed in practice in a small percentage of patients despite the labeled contraindication without noted adverse effects. Acute nitrate therapy should be avoided in the context of episodic PDE-5 exposure, likely identified through systematic processes. Few data exist defining risk with lower-intensity daily PDE-5 administration. Chronic co-administration is not recommended but may be navigated with careful risk-benefit determination. Future directions also aim to identify potential areas where nitrate synergy may achieve clinical benefit.

BackgroundAlzheimer’s disease, the most common cause of dementia, causes a progressive and irreversible deterioration of cognition that can sometimes be difficult to diagnose, leading to suboptimal patient care.MethodsWe developed a predictive model that computes multi-regional statistical morpho-functional mesoscopic traits from T1-weighted MRI scans, with or without cognitive scores. For each patient, a biomarker called “Alzheimer’s Predictive Vector” (ApV) was derived using a two-stage least absolute shrinkage and selection operator (LASSO).ResultsThe ApV reliably discriminates between people with (ADrp) and without (nADrp) Alzheimer’s related pathologies (98% and 81% accuracy between ADrp - including the early form, mild cognitive impairment - and nADrp in internal and external hold-out test sets, respectively), without any a priori assumptions or need for neuroradiology reads. The new test is superior to standard hippocampal atrophy (26% accuracy) and cerebrospinal fluid beta amyloid measure (62% accuracy). A multiparametric analysis compared DTI-MRI derived fractional anisotropy, whose readout of neuronal loss agrees with ADrp phenotype, and SNPrs2075650 is significantly altered in patients with ADrp-like phenotype.ConclusionsThis new data analytic method demonstrates potential for increasing accuracy of Alzheimer diagnosis.
