While the gold standard for CSF leak confirmation is surgical exploration, testing nasal fluid for beta-2 transferrin (B2Tf) via agarose gel electrophoresis followed by immunofixation (AGEI) remains the initial non-invasive CSF confirmatory test of choice. However, AGEI requires subjective ...
Our aim was to determine L-4, IL-5, IL-6, IL-12p70, IL-13, IL-33, GM-CSF, periostin, and TSLP cytokine levels in the nasal fluid of childhood asthma patients in clinical remission. Because sampling nasal fluid is an easy, non-invasive, non-traumatic sample collection method from chi...
Although blood is considered one of the most promising fluid biomarker candidates for AD, this approach still has to overcome critical issues, such as low concentrations (e.g. p-tau: ~ pg/ml)8, plasma stability, blood–brain barrier penetration of key protein biomarkers to be used for ...
Analysis of nasal secretions for glucose with glucose-oxidase test paper systems (Clinistix or Tes-Tape) is widely used clinically to confirm the presence of cerebrospinal fluid (CSF) rhinorrhea. Studies on 164 subjects, without CSF rhinorrhea (72 normals and 92 patients with allergic or infectiou...

which allow CSF to flow into the nasal mucosa (Sun et al.2018). Therefore, the perineural spaces around the olfactory nerves are called the olfactory/nasal lymphatic route and are the main drainage routes for CSF and interstitial-fluid (ISF) generated from the brain parenchyma (Fig.1A). The...
The nasal flush is a useful tool for collecting samples of material and fluid found between the external nares and the choanal slit, an area that includes the ventral aspect of the middle nasal concha, the suborbital chamber, and occasionally the preorbital diverticulum of the infraorbital sinus...
It is important to exclude an associatedskull fracturewhich may be indicated by the presence of clear fluid in the nasal cavity. A fracture through the cribriform plate can result in a CSF leak. In an ideal world, you can test forbeta-2-transferrin(present only in CSF, perilymph, and aqu...
as much as 17% of it is sucked into the sinus cavities by force.17This fluid contains allergen(s), viral particles, and bacteria; once inside the sinus cavities, the bacteria adhere to the mucosal lining. The stimulation of epithelial cells by bacterial products (lipopolysaccharide by...
In the guinea pig model with allergic rhinitis, number of eosinophil cells in nasal lavage fluid and nasal mucosa inclined to increase 8 h post intranasal drip of IgY compared with that after 4 h, by contrast, the numbers continued to decline in IgY/PMAA nanogel group, indicating the long-...
