[Progress of IgG4 related sino-nasal diseases]
Abstract:
IgG4 related disease(IgG4-RD)is a newly recognized chronic fibroinflammatory disease in recent years.It is often accompanied by the significant elevation of serum IgG4 level,but the diagnostic specificity of the elevation is not high.The diagnosis is mainly based on histopathology,which is characterized by dense IgG4 positive plasma cell infiltration,storiform fibrosis and obliteran phlebitis.IgG4-RDcan involve various organs of the body,but less involve the nasal cavity and paranasal sinuses.The nasal symptoms of IgG4-RD are lack of specificity,so it is easier to be missed and misdiagnosed.PET/CT has important value in the diagnosis and differential diagnosis of the disease.We reviewed the relevant studies of IgG4-RD in nasal cavity and paranasal sinus in recent years,in order to improve the understanding of IgG4-RD in nasal cavity and paranasal sinuses and to improve the diagnosis and treatment rate.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Asthma-IV: Diagnostic and Management
Clinical Assessment for Asthma:
This is the first step in diagnosing and managing asthma. It includes:
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Epistaxis
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...
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
