Tetanus01:29

Tetanus

Tetanus is a life-threatening neurological disorder characterized by persistent muscle contractions and spastic paralysis. It is caused by Clostridium tetani, a motile, Gram-positive, rod-shaped, obligate anaerobe. These bacteria produce terminal endospores, giving them a distinctive “lollipop” or “tennis-racket” appearance. They thrive in anaerobic environments, such as those found in deep puncture wounds.Once introduced into the body, the spores germinate into vegetative cells. These cells...
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...
Hyperthyroidism II: Pathophysiology01:27

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
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...
Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...

Summary
This summary is machine-generated.

Terson's syndrome, characterized by intraocular hemorrhage after subarachnoid hemorrhage, is an under-reported condition linked to increased mortality. Prompt diagnosis via funduscopy is crucial for managing this adverse prognostic factor.

Area of Science:

  • Neurology
  • Ophthalmology
  • Neurosurgery

Background:

  • Terson's syndrome involves intraocular hemorrhage (IOH) following subarachnoid hemorrhage (SAH).
  • Its presence correlates with increased mortality in SAH patients.
  • This case highlights the importance of recognizing Terson's syndrome.

Observation:

  • A 71-year-old male with SAH and an internal carotid artery aneurysm developed visual impairment.
  • Retinal hemorrhages were identified on CT scans and confirmed by funduscopy.
  • The patient's poor neurological state persisted, leading to expiration.

Findings:

  • Terson's syndrome occurs in up to 40% of aneurysmal bleeds.
  • Sudden increases in intracranial pressure (ICP) during aneurysmal rupture are implicated.
  • Funduscopy is the gold standard for diagnosis; CT may reveal retinal hemorrhages.

Implications:

  • Terson's syndrome is a frequent yet under-reported complication of SAH.
  • Suspected visual loss post-SAH necessitates funduscopy to detect Terson's syndrome.
  • Identifying Terson's syndrome is vital as it indicates a poorer prognosis.
