Insights

Idiopathic hidden arterial epistaxis commonly bleeds from the olfactory cleft, inferior, and middle meatus. Awareness of less common sites like the nasal floor and nasopharynx is also crucial for effective treatment.

Area of Science:

  • Otolaryngology
  • Rhinology
  • Medical Imaging

Background:

  • Idiopathic hidden arterial epistaxis presents a diagnostic challenge.
  • Endoscopic examination is key to identifying bleeding sources.

Purpose of the Study:

  • To determine the frequency distribution of bleeding sites in idiopathic hidden arterial epistaxis.
  • To enhance understanding of common and uncommon epistaxis locations.

Main Methods:

  • Retrospective cohort study of 107 patients with hidden arterial epistaxis.
  • Endoscopic examination to identify bleeding sites.

Main Results:

  • The olfactory cleft (47 patients), inferior meatus (29), and middle meatus (11) were the most common bleeding sites.
  • Less frequent sites included the nasal floor (11) and nasopharynx (2).
  • Bleeding points often appeared as volcano-like bumps (75 patients).

Conclusions:

  • The olfactory cleft, inferior meatus, and middle meatus are primary sites for idiopathic hidden arterial epistaxis.
  • Uncommon sites and multiple bleeding points require clinical consideration.

Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Conserved Binding Sites

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Bleeding in Fresh Concrete01:22

Bleeding in Fresh Concrete

Bleeding in fresh concrete occurs when water from the mix rises to the surface. This happens because the mix's solid components fail to retain all the water as they settle, leading to separation where water collects at the top. The severity of bleeding can be measured by assessing the total settlement or by noting the decrease in height per unit height of concrete.
Bleeding can cause several issues in the concrete structure. Sometimes, the rising water gets trapped beneath large aggregate...

Ligand Binding Sites

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
