Complications are not common but include infection, lung abscess, and bronchopleural fistula (a fistula between the pleural space and the bronchial tree). [4] A bronchopleural fistula results when there is a communication between the laceration, a bronchiole, and the pleura; it can cause air to leak into the pleural space despite the placement of a chest tube.

With an active surface area of 160 cm 2, the nasal cavity is another noteworthy route of mucoadhesive administration. Due to the sweeping motion of the cilia that lines the mucosa, nasal mucus has a quick turnover of 10 to 15 minutes. Because of this, the nasal cavity is most suitable for rapid, local medicinal dosages.
Mucosal immunology is the study of immune system responses that occur at mucosal membranes of the intestines, the urogenital tract, and the respiratory system. [1] The mucous membranes are in constant contact with microorganisms , food, and inhaled antigens . [ 2 ]
The cells in the respiratory epithelium are of five main types: a) ciliated cells, b) goblet cells, c) brush cells, d) airway basal cells, and e) small granule cells (NDES) [6] Goblet cells become increasingly fewer further down the respiratory tree until they are absent in the terminal bronchioles; club cells take over their role to some extent here.

After delivery, if the patient is symptomatic, resection is mandated. If the infant is asymptomatic, the need for resection is a subject of debate, though it is usually recommended. Development of recurrent infections, rhabdomyosarcoma , adenocarcinomas in situ within the lung malformation have been reported.
However, in a subsequent pregnancy with an Rh positive fetus, the formed antibodies can cross the placenta and attack the red blood cells of the fetus, a process called Rh isoimmunization that can result in a condition known as Rhesus disease or hemolytic disease of the fetus and newborn.
In pregnancies between 32 and 34 weeks (right around the time that fetal lungs mature) vaginal fluid can be tested to determine fetal lung maturity using chemical markers which can help to decide if corticosteroids should be given. [9]
A new study that includes a thousand additional workers shows that the declines have persisted over time. [34] Prior to 9/11, 3% of firefighters had below-normal lung function, one year after 9/11 nearly 19% did, and six years later it stabilized at 13%.
