Dr. Smith (Chairman): To start the evening, I might remind you that 6 years ago a similar group took advantage of their presence at the International Congress in Montreal to gather together informally for the exchange of ideas about hyaline membrane disease. The one major result of that discussion was the agreement that, whatever hyaline membrane disease is, it should thereafter always be called the idiopathic respiratory distress syndrome. As you may know, the syndrome is now referred to more firmly than ever as hyaline membrane disease; nevertheless, something of value was accomplished in the exchange of ideas and in the focusing of international attention upon central rather than peripheral aspects of a previously ill-defined problem. In organizing tonight's meeting, I know Dr. Cornblath hopes something of a similar nature can occur with regard to problems of carbohydrate and fat metabolism in newborn infants. Some of us, I am afraid, would have said 6 years ago that newborn infants actually had no problems of this sort. It was largely through Marvin Cornblath's alertness and continued investigations that we now know the subject as one of great importance and interest. Yet, I think one of the reasons we are here is not only to discuss how these matters look to all the rest of us, but to find out if anyone else sees quite as many infants with significant hypoglycemia as seem to be encountered in Chicago. What it is that we are missing in other cities, or what Dr. Cornblath is doing that we are not, are aspects which, I hope, can come out in the discussion tonight.
