Abstract
On Oct. 23, 1931, there came to my office for the first time a man, aged 48, whose chief complaints were shortness of breath and a feeling of abdominal distention. The patient was white, was married and his occupation was assistant manager of an office building. The patient's story was that about six weeks previously, while getting out some old blue prints, which were covered with dust, he inhaled a good deal of the dust and began to have paroxysms of severe coughing, which had continued more or less constantly. After enduring these coughing attacks for about a month he consulted a physician, who prescribed various forms of treatment but with little success. About October 13, while under treatment for the cough, he suddenly developed dyspnea and a feeling of abdominal distention, particularly above the umbilicus. He found it difficult to breathe when lying down or when standing perfectly erect
