Sympathetic Activation01:16

Sympathetic Activation

The sympathetic division can influence tissues and organs by releasing norepinephrine at peripheral synapses and distributing epinephrine and norepinephrine through the bloodstream. In times of crisis or stress, sympathetic activation occurs, which is regulated by sympathetic centers in the hypothalamus. As a result, sympathetic activation prepares the body for physical exertion, rapid ATP production, and heightened alertness, allowing individuals to respond effectively to challenging or...
Transient Ischemic Attack l: Introduction01:26

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
Papillary Dermis01:11

Papillary Dermis

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
Graves Disease II: Pathophysiology01:24

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
Pericarditis II: Clinical Features and Diagnostic Tests01:19

Pericarditis II: Clinical Features and Diagnostic Tests

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Summary

This case report details the immunopathology of Terson syndrome, revealing high endoglin expression in the eye. This suggests endothelial cell activation and potential regeneration following subarachnoid hemorrhage.

Area of Science:

  • Ophthalmology
  • Neuropathology
  • Immunohistochemistry

Background:

  • Terson syndrome is characterized by vitreous hemorrhage associated with subarachnoid hemorrhage.
  • The underlying immunopathology and cellular changes in Terson syndrome remain incompletely understood.
  • Endoglin (CD105) is a marker of endothelial cell activation and angiogenesis.

Observation:

  • This study presents an observational case report of a patient with Terson syndrome.
  • Histopathology and immunohistochemical staining were performed on ocular tissue.
  • The analysis focused on endoglin (CD105) expression within the affected eye.

Findings:

  • High papillary endoglin expression was observed in the patient's eye.
  • The upregulation of endoglin indicates significant activation of endothelial cells.
  • These findings provide insights into the cellular response within the eye in Terson syndrome.

Implications:

  • The observed endoglin upregulation may signify an active regeneration process.
  • This suggests a potential role for endothelial cell response in the recovery from ocular complications of subarachnoid hemorrhage.
  • Further research into endothelial markers could elucidate therapeutic targets for Terson syndrome.
