Insights

Internal carotid artery dissection (ICAD) can cause vision problems and Horner syndrome. Ocular symptoms may be the first sign of ICAD, even without classic symptoms.

Area of Science:

  • Vascular Neurology
  • Ophthalmology

Background:

  • Internal carotid artery dissection (ICAD) involves arterial wall intima disruption, leading to intramural hematoma.
  • This hematoma can compress the vessel's true lumen, causing stenosis or occlusion.

Purpose of the Study:

  • To summarize the ocular manifestations associated with internal carotid artery dissection (ICAD).
  • To categorize these ocular findings for better understanding and diagnosis.

Main Methods:

  • Literature review and synthesis of case reports and studies on ICAD.
  • Categorization of ocular manifestations into visual symptoms, oculosympathetic palsy, and ocular motor nerve palsy.

Main Results:

  • ICAD can present with a range of ocular symptoms, not limited to the classic triad.
  • Ocular manifestations can be the initial or sole presenting signs of ICAD.
  • Key categories include visual disturbances, Horner syndrome, and cranial nerve palsies affecting eye movement.

Conclusions:

  • Ocular manifestations are a significant aspect of internal carotid artery dissection (ICAD).
  • Recognizing these varied ocular signs is crucial for timely ICAD diagnosis, especially when classic symptoms are absent.

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Internal Energy02:00

Internal Energy

The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Internal Energy

The internal energy of a thermodynamic system is the sum of the kinetic and potential energies of all the molecules or entities in the system. The kinetic energy of an individual molecule includes contributions due to its rotation and vibration, as well as its translational energy. The potential energy is associated only with the interactions between one molecule and the other molecules of the system. Neither the system's location nor its motion is of any consequence as far as the internal...

Internal Receptors01:31

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

International System of Units

The International System of Units, known as the SI system, is a universally accepted measurement system recognized and used worldwide. The SI system is based on a set of three base units considered absolute, and their values do not change with location. These base units are meters, kilograms, and seconds.
Prefixes are used to define both larger and smaller quantities in the SI system. For example, milli, micro, and nano define smaller quantities, while kilo, mega, and giga are used to define...
