Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

ECG Interpretation of Arrhythmias I: Sinus Arrhythmias

ECG Interpretation of Arrhythmias I: Sinus Arrhythmias

Arrhythmias are disturbances in the heart's rhythm that lead to abnormal heartbeats. These irregularities can originate from different parts of the heart and are classified based on their origin and nature.
Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...

Acute Pancreatitis II: Clinical Manifestations and Management

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Angina III: Clinical Manifestations and Assessment

Angina III: Clinical Manifestations and Assessment

Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis II: Clinical Manifestations and Diagnostic Tests

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Summary

Silent sinus syndrome (SSS) causes gradual, one-sided eye and facial changes due to maxillary sinus collapse. This condition often presents without prior sinus symptoms, leading to enophthalmos and hypoglobus.

Area of Science:

Ophthalmology
Otorhinolaryngology
Radiology

Background:

Silent sinus syndrome (SSS) is a rare condition characterized by progressive enophthalmos and hypoglobus.
It results from chronic maxillary sinus disease, often without preceding sinus symptoms.

Observation:

A retrospective review identified 7 cases of SSS between 2005 and 2017.
Patients presented with unilateral enophthalmos and hypoglobus; 3 experienced vertical diplopia.
Two cases had a history of trauma, while the others had no relevant history.

Findings:

The primary finding is maxillary sinus collapse due to ostial obstruction and negative pressure.
Subclinical maxillary sinus disease is the underlying pathology.
Surgical interventions included functional endoscopic sinus surgery and orbital floor support.

Implications:

SSS is a slow, progressive disorder requiring accurate diagnosis.
Understanding the pathophysiology aids in managing enophthalmos and hypoglobus.
Early recognition and intervention can improve patient outcomes.
