By Fred Brady. Crowding into the American College of Physicians’ session in Mechanics Building yesterday there was suddenly a voice behind me, and it wasn’t soothing or bedside manners as it said: “What a tremendous show this is. Amazing.” And that is how I met the most enthusiastic member of this big conference of 6000 physicians --M. Abdullah, M.D., of Lahore, Pakistan. He is an intense young man of 34 and his enthusiasms seem boundless--for medical improvement in Pakistan, for American aid to such medical advance, for the vast medical facilities of Boston, and for Pakistan cricket and American baseball. But Pakistan, that nation of more than 80,000,000 persons, is his first concern and he is outspokenly proud of what he terms “the tremendous improvement in medicine” there in the past 10 years. “You do not see a man dying in the streets now as one might have in the old times.” Dr. Abdullah said. Dr. Abdullah gets really excited as he discusses the advances of the past 10 years which he credits to the Pakistan Ministry of Health with a major assist from the United States in economic aid and in exchange programs of doctors and medical technicians. He himself came to this country in such an exchange program four months ago and is now studying internal medicine in Texas. “But,” he smiled, “my colleagues in Texas told me I must come to this meeting in Boston. “Ah, this is a wonderful meeting. The colleagues in Boston have been very helpful and very hospitable. For someone like myself this is a unique opportunity. “Do you know, all one can learn in one week here is worth the study of weeks and months.”
