hypersensitivity pneumonitis  extrinsic allergic alveolitis; a hypersensitivity reaction to repeated inhalation of organic particles, usually on the job, with onset a few hours after exposure to the allergen.

pneumonitis

[no̅o̅′mənī′tis] pl. pneumonitides

Etymology: Gk, pneumon + itis

inflammation of the lung. Pneumonitis may be caused by a virus or may be a hypersensitivity reaction to chemicals or organic dusts, such as bacteria, bird droppings, or molds. It is usually an interstitial, granulomatous, fibrosing inflammation of the lung, especially of the bronchioles and alveoli. Dry cough is a common symptom. Treatment depends on the cause but includes removal of any offending agents and administration of corticosteroids to reduce inflammation. Compare pneumonia.

pneumonitis [noo″mo-ni´tis]

inflammation of the lung; see also pneumonia.

hypersensitivity pneumonitis a respiratory hypersensitivity reaction to repeated inhalation of organic particles, usually in an occupational setting, with onset a few hours after exposure to the allergen. Many different substances are potential causes of the condition; see bagassosis, farmer's lung, and pigeon breeder's lung. Characteristics include fever, fatigue, chills, unproductive cough, tachycardia, and tachypnea; in the chronic form there is interstitial fibrosis with collagenous thickening of the alveolar septa. Called also extrinsic allergic alveolitis.

radiation pneumonitis lung inflammation resulting from radiation exposure, usually radiation therapy, with coughing, dyspnea, and alveolar infiltration of secretions, leading to mild to severe or even fatal fibrosis 6 to 9 months after the exposure.

Patient discussion about pneumonitis.

Q. Can I catch pneumonia, if I go outside with wet hair? My Mother used to tell me when I was a kid that if I go outside with wet hair, I will catch pneumonia. Is this true?

A. IF YOUR WET WATER REMOVES MORE HEAT FROM THE BODY FASTER THAN WHEN YOUR DRY ALSO CONSIDER THAT HEAT RISES WE LOSE MOST OF THE TOP OF OUR HEADS WHEN YOU ADD WATER YOU DRAMATICLY LOWER YOUR TEMPERATURE ON YOUR HEAD AND ALSO CONSIDER THAT IF YOUR MOVING FROM A COLD PLACE TO A WARM PLACE SEVERAL TIMES A DAY LIKE A FREEZER ON A HOT SUMMER DAY OR INDOORS TO OUT DOORS IN THE WINTER TIME 20 MINUTE INTERVALS I WILL SAY YES YOU CAN CATCH COLD AN GET THE SNIFFLES, COUGH AND OR SORE THROUGHT BUT I DO AGREE THAT YOU WON'T NECISARLY GET PENOMNIA FROM JUST WET HAIR ALONE THERES MANY MORE FACTORS FOR THAT.

Q. Do I have Bronchitis? I had a cold and since then I have a severe cough which I can't seem to get rid of. Is this bronchitis? Does it need to be treated or will it go away by itself?

A. Bronchitis most commonly occurs after an upper respiratory infection such as the common cold or a sinus infection. You may see symptoms such as fever with chills, muscle aches, nasal congestion, and sore throat. Most cases of bronchitis clear up on their own, however if you have complications, go see your doctor. If the cough is very severe and interrupts your sleep, if you are wheezing or have a fever for longer than a few days, then you should see your Doctor.

Q. PNEUMONIA is it viral or bacterial

A. Pneumonia Information

Pneumonia is an inflammation and consolidation f lung tissue to due to an infectious agent- typically a bacteria or a virus, and is usually acquired in a community setting. Bacterial pneumonia occurs more often by a microbe called S. Pneumo. Half of all people infected with this bacteria show no symptoms. Compared with viral pneumonia, bacterial pneumonia has a shorter duration and is also more severe in the damage the bacteria can do to the patient. If left untreated, pneumonia can lead to the critical diseases of meningitis or sepsis.
Approximately 2 to 5 million people acquire pneumonia every year. 40 to 60 thousand people die due to pneumonia every year, and pneumonia is the most common infectious cause of death that exists. More men get pneumonia than women. About 20 percent of CAP cases are viral rather than bacterial. So most of the time, an antibiotic will be needed for the pneumonia patient. Also, about 10 million doctor visits are due to CA
