Prednisone is a synthetic glucocorticoid used for its anti-inflammatory and immunosuppressive properties. [36] [37] Prednisone is a prodrug; it is metabolised in the liver by 11-β-HSD to prednisolone, the active drug. Prednisone has no substantial biological effects until converted via hepatic metabolism to prednisolone. [38]
Acute bronchitis typically resolves on its own with time. [citation needed] In 2015 there were about 291 million cases. [1] These resulted in 2.74 million deaths down from 3.4 million deaths in 1990. [5] [2] This was 4.8% of all deaths in 2013. [5]
Acute bronchitis usually lasts a few days or weeks. [29] It may accompany or closely follow a cold or the flu, or may occur on its own. Bronchitis usually begins with a dry cough, including waking the patient at night. After a few days, it progresses to a wetter or productive cough, which may be accompanied by fever, fatigue, and headache.
Another common sign of bronchitis is a cough lasting ten days to three weeks. If the cough lasts longer than a month, it may become chronic bronchitis. In addition, a fever may be present. Acute bronchitis is normally caused by a viral infection. Typically, these infections are rhinovirus, adenovirus, parainfluenza, or influenza. No specific ...
[2] [4] [5] Non-asthmatic eosinophilic bronchitis is different from asthma in that it does not have airflow obstruction or airway hyperresponsiveness. [6] Along with eosinophils, the number of mast cells , another type of white blood cell, is also significantly increased in the bronchial wash fluid of eosinophilic bronchitis patients compared ...
5), corticosterone (C 21 H 30 O 4), cortisone (C 21 H 28 O 5) and aldosterone (C 21 H 28 O 5) (cortisone and aldosterone are isomers). The main corticosteroids produced by the adrenal cortex are cortisol and aldosterone. [1] The etymology of the cortico-part of the name refers to the adrenal cortex, which makes these steroid hormones. Thus a ...
Clinical studies have demonstrated that chewing sugarless gum for 20 minutes after eating can prevent tooth decay. “This is due to the mechanics of the chewing," pediatric dentist Ashley Lerman ...
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
