There are many causes that can induce or contribute to the development of bronchiectasis. The frequency of these different causes varies with geographic location. [24] Cystic fibrosis is identified as a cause in up to half of cases. [3] Bronchiectasis without CF is known as non-CF bronchiectasis.
[4] [5] [6] Due to its rarity it presents a difficulty in adult diagnoses, and its initial presentation can be confused with septic shock. [7] Diagnosis requires an appropriate clinical history, the characteristic expiratory airway collapse on radiological investigation, and exclusion of other causes of congenital and acquired bronchiectasis.
Respiratory syncytial virus (RSV), [a] also called human respiratory syncytial virus (hRSV) and human orthopneumovirus, is a virus that causes infections of the respiratory tract. It is a negative-sense, single-stranded RNA virus. [2] Its name is derived from the large cells known as syncytia that form when infected cells fuse. [2] [3]
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction.Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself.
Tracheobronchomegaly is a very rare congenital disorder of the lung primarily characterized by an abnormal widening of the upper airways. [2] The abnormally widened trachea and mainstem bronchi are associated with recurrent lower respiratory tract infection and copious purulent sputum production, eventually leading to bronchiectasis and other respiratory complications.
Bronchomalacia is a term for weak cartilage in the walls of the bronchial tubes, often occurring in children under a day. Bronchomalacia means 'floppiness' of some part of the bronchi. Patients present with noisy breathing and/or wheezing. There is collapse of a main stem bronchus on exhalation. If the trachea is also involved the term ...
The disease is more common in males, [25] with the male to female ratio at 1.4–2:1 (or about 5 men to 3 women). [4] The average onset of the disease is around age 40, and two-thirds of those affected are non-smokers, although smoking is not believed to be a cause. [7] The presence of HLA-Bw54 increases the risk of diffuse panbronchiolitis 13. ...
Bronchorrhea is the production of more than 100 mL per day of watery sputum. [1] Chronic bronchitis is a common cause, but it may also be caused by asthma, [2] pulmonary contusion, [3] bronchiectasis, tuberculosis, cancer, scorpion stings, severe hypothermia and poisoning by organophosphates and other poisons.
