Mother worked in hosiery mills and then in 1966 @ Corning Glass Works working with glass cane cutting them down into various lengths to make resistors. She would come home covered in this "glass dust". Immediate family members that lived together with my mother had some sort of lung issues (i.e. grandfather had 1 lung removed due to cancer in the 1970's, grandmother died of lung cancer in 1968, my mother had many lung issues, placed on prednisone, had a heart attack, passed away in 1993. Sister, 5 yrs older than myself hospitalized 3 yrs ago due to lung issues) I was born in 1963 and have been diagnosed with "chronic interstitial lung disease" with COPD & persistent dyspnea" by my family physician. When I was 16 yrs old and a non-smoker, I contracted pleurisy, went to the emergency room at the local hospital was given Tylenol 3, told to get moderate bed rest, see our own doctor in a few days if symptoms did not get better (we didn't have a regular doctor). Anyway, I started smoking at age 18, have had pneumonia and the flu which took 2 weeks to get over. I quit smoking for two years, the started back again. I am now 49, have had 3 PFT's all of which show a "severly low diffusing capacity" which is 27% as of 4/27/11. I have had 2 CT scans which did not change that showed "lungs mildly hyperinflated"..."the lung bases demonstrate dependent atelectasis"..."a suggestion of prominent reticulonodular opacities observed along the interlobular septa"...and "there is a 3mm noncalcified pulmonary nodule within the right lung base". Otherwise, everything else shows normal on the CT scan, including heart. I do have severe breathing problems during any activity and have had very sharp chest pains from doing just minor things such as washing/drying my hair & changing out air filters in the a/c unit. I am on Spiriva, Flovent 110mcg 2 puffs daily & ProAir rescue inhaler. From just this information given to you, which type of ILD would you or could you say this would or could be??
