pneumoconiosis
how many disease entities are there
more than 180
how are the disease entities characterized
acute
sub-acute
chronic inflammatory infiltration of alveolar walls by cells, fluid, and connective tissue
what happens if left untreated
inflammatory process can progress to irreversible pulmonary fibrosis
what does the ILD group comprise of
wide range of illnesses with varied causes, treatments, and prognoses
do all ILD reflect similar anatomic alterations of lungs and cardiopulmonary manifestations
yes
is ILD restrictive or obstructive
restrictive
anatomic alterations: what happens to the alveoli and pulmonary capillaries
they are destroyed
anatomic alterations: what happens to respiratory bronchioles, alveolar ducts, and alveoli
fibrotic thickening
what other things can form in the lungs
granulomas, honeycombing, cavity formation, fibrocalcific pleural plaques, bronchospasm and excessive bronchial secretions
how should you categorize ILD
group them according to their occupational or environmental exposure, disease associations, and specific pathology
what are occupation/environmental ILD inorganic exposures
asbestosis, coal dust, silica, beryllium, aluminum, barium, clay, iron, certain talcs
what does occupation/environmental iLD organic exposures cause
hypersensitivity pneumonitis
occupation/environmental - therapeutic exposures
antibiotics antiiinflammatory agents cardiovascular agents drug-induced systemic lupus erythematosus irritant gases radiation therapy
what can cause hypersensitivity pneomonitis
moldy hay silage moldy sugar cane mushroom compost barly cheese wood pulp, bark, dust cork dust bird droppings paints
