Dr. Schiffman received his B.S. degree with High Honors in biology from Hobart College in 1976. He then moved to Chicago where he studied biochemistry at the University of Illinois, Chicago Circle. He attended Rush Medical College where he received his M.D. degree in 1982 and was elected to the Alpha Omega Alpha Medical Honor Society. He completed his Internal Medicine internship and residency at the University of California, Irvine.

What are examples of hypersensitivity pneumonitis?
Examples of hypersensitivity pneumonitis include:
farmer's lung disease from exposure to mold spores in hay,
pigeon breeder's disease from exposure to protein particles in pigeon droppings,
sauna takers' disease from exposure to mold growing in wet containers,
mushroom workers' disease from exposure to moldy compost,
bagassosis from exposure to moldy sugar cane, and
many others.
The most common form of hypersensitivity pneumonitis results from exposure to pet birds.
How is hypersensitivity pneumonitis diagnosed?
Many people with episodes of hypersensitivity pneumonitis are probably unrecognized and undiagnosed. Some cases believed to be viral pneumonias may actually be hypersensitivity pneumonitis. The patient's history of repeated episodes of typical symptoms, hours after exposure to certain environments are important in establishing the diagnosis.
Blood antibody tests and skin tests against certain offending molds, bacteria, or particles are also available but their results are usually inconclusive. The interpretation of these tests is complicated, and is best performed by a doctor experienced in hypersensitivity pneumonitis. The most accurate determination of the cause of hypersensitivity pneumonitis is a detailed exposure history.
What is the treatment of hypersensitivity pneumonitis?
The most important treatment of hypersensitivity pneumonitis is avoidance of repeated exposures to the offending particles. With early diagnosis and prevention, the prognosis is good. Prolonged, repeated exposures can lead to permanent lung damage, scarring, and potentially significant disability.
Pulmonary fibrosis is scarring throughout the lungs. Pulmonary fibrosis can be caused by many conditions including chronic inflammatory processes, infections, environmental agents, exposure to ionizing radiation, chronic conditions, and certain medications. Symptoms include shortness of breath, coughing, and diminished exercise tolerance. Treatment options are dependent on the type of pulmonary fibrosis; lung transplant and/or medications are optons.
Mold exposure may cause symptoms in people who are sensitive to molds. Symptoms of mold allergy include sneezing, runny nose, wheezing, coughing, redness of the eyes, and rash. Prevent mold growth by keeping indoor humidity low, between 30%-50%, using bathroom fans when showering, repairing plumbing leaks quickly, and using an air conditioner during humid seasons.
