Attempts have been made to provide a more consistent nomenclature for subtypes of chronic sinusitis. The presence of eosinophils in the mucous lining of the nose and paranasal sinuses has been demonstrated for many people, and this has been termed eosinophilic mucin rhinosinusitis (EMRS). Cases of EMRS may be related to an allergic response ...
Eosinophilia and comparatively fewer cases of hypereosinophilia are associated with the following known diseases that are known or thought to have an allergic basis: allergic rhinitis, asthma, atopic dermatitis, eosinophilic esophagitis, chronic sinusitis, aspirin-exacerbated respiratory disease, allergic bronchopulmonary aspergillosis, chronic ...
Chronic rhinosinusitis is characterized/shaped by an impaired nasal inspiration, feelings of pressure and swelling in the facial area, as well as a higher susceptibility to infection. [ 2 ] Severe complications are rare, although orbital and intracranial inflammations can occur.
Rhinitis is commonly caused by a viral or bacterial infection, including the common cold, which is caused by Rhinoviruses, Coronaviruses, and influenza viruses, others caused by adenoviruses, human parainfluenza viruses, human respiratory syncytial virus, enteroviruses other than rhinoviruses, metapneumovirus, and measles virus, or bacterial ...
Depending on eosinophil target-organ infiltration, the clinical presentation of hypereosinophilic syndrome (HES) varies from patient to patient. [13] Individuals with myeloproliferative variant HES may be more likely to experience mucosal ulcerations involving the genitalia or airways, while patients with lymphocytic variant HES typically exhibit prominent skin symptoms such as urticarial ...
The ionic charges of mucin are mainly provided by acidic amino acids including aspartic acid (pKa=3.9) and glutamic acid (pKa=4.2). The charges of acidic amino acids will change with environmental pH value due to acid dissociation and association. Aspartic acid, for example, has a negative side chain when the pH value is above 3.9, while a ...
Eosinophilic granulomatosis with polyangiitis consists of three stages, but not all patients develop all three stages or progress from one stage to the next in the same order; [7] whereas some patients may develop severe or life-threatening complications such as gastrointestinal involvement and heart disease, some patients are only mildly affected, e.g. with skin lesions and nasal polyps.

Eosinophilia is the main feature of diagnostic criteria for Loffler's syndrome. Eosinophils are white blood cells that fight infection by destroying foreign substances in the body. This increase is determined through a blood test called a complete blood count, or CBC .
