Early initiation of intravenous cyclophosphamide and one-year outcome in super-refractory cryptogenic-new onset refractory status epilepticus.

To explore the potential efficacy of early initiation of intravenous cyclophosphamide (IVCPA), we reviewed consecutive four cases of super-refractory cryptogenic-new onset refractory status epilepticus (C-NORSE) between 2015 and 2023. We compared functional outcomes at 3 months and 1 year after the onset between patients who received IVCPA within 20 days (early-treated) and those who received it later (late-treated). All patients (median age: 43 years) had a prodromal fever.

Discordant Diagnosis of Coronary Microvascular Dysfunction by Microvascular Resistance Reserve: Transthoracic Doppler Echocardiography vs Bolus Thermodilution Method.

Background: Epicardial stenosis and coronary microvascular dysfunction (CMD) may coexist in patients with chronic coronary syndrome (CCS). Microvascular resistance reserve (MRR) has been demonstrated to be a valid cross-modality metric using continuous saline infusion thermodilution and intracoronary Doppler flow velocity methods. This study aimed to investigate the prevalence and diagnostic concordance of CMD defined by MRR using two methods-stress transthoracic Doppler echocardiography (S-TDE) and the invasive bolus thermodilution method (B-Thermo)-in patients with functionally significant epicardial stenosis.

Punctate Hippocampal Hyperintensities on Diffusion-Weighted Imaging Following Epileptic Seizures: A Case Report.

Punctate hippocampal hyperintensity (PHH) on diffusion-weighted imaging (DWI) is a well-known observation in patients with transient global amnesia (TGA), which is characterized by acute self-limiting episodes of anterograde and retrograde amnesia. These lesions occur unilaterally or bilaterally in the CA1 regions of the hippocampus, which are crucial for memory processes. PHH on DWI is well-documented in TGA but rare in other conditions.

Myelin measurement in amyotrophic lateral sclerosis with synthetic MRI: A potential diagnostic and predictive method.

Background: Myelin damage has recently been highlighted as a major causative factor of amyotrophic lateral sclerosis (ALS). Although myelin damage has been pathologically identified in ALS, it has not been clinically evaluated. This study aimed to quantify myelin volume using synthetic MRI to evaluate myelin damage in patients with ALS, and determine its association with clinical parameters.

Prognostic Value of Endogenous-Type Coronary Microvascular Dysfunction After Elective Percutaneous Coronary Intervention.

Background: Global coronary flow reserve (G-CFR) impairment represents coronary microvascular dysfunction (CMD) and correlates with poor prognosis. Hyperemic coronary flow is reduced in conventional CMD, but normal or mildly reduced with elevated resting flow in endogenous-type CMD (E-CMD). This retrospective study assessed the prognostic value of post-percutaneous coronary intervention (PCI) CMD, focusing on E-CMD.

Impact of coronary revascularization on coronary flow capacity measured by transthoracic Doppler echocardiography in patients with chronic coronary syndrome.

Coronary flow capacity (CFC) integrates quantitative assessment of hyperemic myocardial blood flow and coronary flow reserve. We aimed to evaluate the effect of elective percutaneous coronary revascularization (PCI) on CFC using serial stress transthoracic Doppler echocardiography (STDE). Overall, 148 stable patients underwent STDE of the left anterior descending arteries (LAD), before and after elective PCI.

Prognostic value of global coronary flow reserve before and after elective percutaneous coronary intervention in patients with chronic coronary syndrome.

Background: Impaired global coronary flow reserve (G-CFR), evaluated through phase-contrast cine cardiovascular magnetic resonance (PC-CMR), has been linked to worse outcomes in patients with cardiovascular disease. This study aimed to investigate the prognostic value of G-CFR improvement, as evaluated using PC-CMR imaging pre- and post-percutaneous coronary intervention (PCI).

Methods: In this single-center study, 320 patients with chronic coronary syndrome (CCS) who underwent pre- and post-PCI PC-CMR measurements were followed up to determine major adverse cardiac or cerebrovascular events (MACCE) predictors.

Association between optical coherence tomography-defined culprit morphologies and changes in hyperemic coronary flow after elective stenting assessed by transthoracic Doppler echocardiography.

Background: Stress-transthoracic Doppler echocardiography (S-TDE) provides a noninvasive assessment of coronary flow parameters in the left anterior descending artery (LAD). However, the association between morphological characteristics and coronary flow changes after elective percutaneous coronary intervention (PCI) remains unclear. We aimed to evaluate the relationships between periprocedural coronary flow changes observed on S-TDE and lesion-specific plaque characteristics obtained by optical coherence tomography (OCT) in the interrogated vessels in patients with chronic coronary syndrome (CCS).

Clodronate liposome treatment contributes to the nerve regeneration in corneal nerve involvement of diabetic mice.

The dense nerve and thin vascular structure of the corneal tissue provide the refractive function in healthy eyes. Diabetes mellitus causes ocular complications including corneal opacification because of corneal nerve degeneration. Diabetic neurotrophic keratopathy is characterized by reduced corneal sensitivity, delayed corneal wound healing, and nerve degeneration.

Predictors and prognostic value of coronary computed tomography angiography for unrecognized myocardial infarction in patients with chronic coronary syndrome.

Objective: Unrecognized myocardial infarction (UMI) on delayed-enhancement cardiac magnetic resonance imaging (DE-CMR) and coronary computed tomography angiography (CCTA) derived high-risk features provide prognostic information in patients with chronic coronary syndrome (CCS). The study aimed to assess the prognostic value of UMI and predictors of UMI using CCTA in patients with CCS who underwent elective percutaneous coronary intervention (PCI).

Methods: This study enrolled 181 patients with CCS who underwent DE-CMR and CCTA before elective PCI.

Prognostic Value of Integrated Assessment of Cardiac Magnetic Resonance-Derived Global Coronary Flow Reserve and Cardiopulmonary Exercise Testing-Derived Peak Oxygen Consumption in Patients With Acute Myocardial Infarction.

This study investigated the prognostic value of cardiovascular magnetic resonance (CMR)-derived global coronary flow reserve (G-CFR) in addition to cardiopulmonary exercise testing (CPET) variables in patients with acute myocardial infarction (AMI). We investigated 127 patients with AMI who underwent primary or urgent percutaneous coronary intervention (PCI) and post-intervention CMR and CPET. The incidence of major cardiac and cerebrovascular events (MACCE), defined as all-cause death, recurrent non-fatal myocardial infarction, re-hospitalization due to congestive heart failure, and stroke, was evaluated (median follow-up, 2.

Predictors of Optical Coherence Tomography-Defined Calcified Nodules in Patients With Acute Coronary Syndrome - A Substudy From the TACTICS Registry.

Background: Recent studies suggest that the presence of calcified nodules (CN) is associated with worse prognosis in patients with acute coronary syndrome (ACS). We investigated clinical predictors of optical coherence tomography (OCT)-defined CN in ACS patients in a prospective multicenter registry.

Methods And Results: We investigated 695 patients enrolled in the TACTICS registry who underwent OCT assessment of the culprit lesion during primary percutaneous coronary intervention.

Association of Coronary Computed Tomography-Defined Myocardial Bridge With Pre- and Post-Procedural Fractional Flow Reserve in Patients Undergoing Elective Percutaneous Coronary Intervention.

Background: Myocardial bridge (MB) is a common coronary anomaly characterized by a tunneled course through the myocardium. Coronary computed tomography angiography (CCTA) can identify MB. The impact of MB detected by CCTA on coronary physiological parameters before and after percutaneous coronary intervention (PCI) is unknown.

Multimodality Imaging of Fabry Disease Cardiomyopathy Complicated With Coronary Vasospasm.

A 41-year-old man with resting angina was diagnosed with a coronary vasospasm and subsequently with Fabry disease exhibiting low serum α-galactosidase A activity. High computed tomography (CT)-derived extracellular volume was detected in the apical inferior wall of the left ventricle suggesting myocardial fibrosis, potentially from vasospasm-related ischemia and/or microvascular dysfunction.
