Summary
Embolic stroke of undetermined source (ESUS) is a type of cryptogenic stroke. Further diagnostics can help identify specific causes, reducing the number of undetermined strokes.
Area of Science:
- Neurology
- Cardiology
- Vascular Medicine
Background:
- Embolic stroke of undetermined source (ESUS) is a significant clinical challenge.
- ESUS represents a subset of cryptogenic strokes with an embolic pattern on imaging.
- Current diagnostic evaluations often fail to identify a specific etiology.
Purpose of the Study:
- To analyze the fundamental concept of ESUS.
- To review recent evidence from cohort studies on ESUS.
- To reassess the definition, etiology, and diagnostic approaches for ESUS.
Main Methods:
- Literature review of recent cohort studies.
- Analysis of the ESUS definition and diagnostic criteria.
- Reassessment of etiological factors and diagnostic strategies.
Main Results:
- ESUS is characterized by an embolic stroke pattern without an identified cause after thorough evaluation.
- Recent cohort studies provide insights into the characteristics and outcomes of ESUS patients.
- Targeted diagnostic interventions can potentially uncover specific stroke etiologies in a subset of ESUS cases.
Conclusions:
- Refining the definition and diagnostic pathways for ESUS is crucial.
- Implementing targeted diagnostics can decrease the overall burden of cryptogenic strokes.
- Identifying specific causes in ESUS patients improves stroke management and prevention strategies.

Acute Coronary Syndrome I: Introduction
265
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Pulmonary Embolism I: Introduction
238
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Seizures: Classification
903
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
