In a paper recently published in this Journal,1 we reported on the pancreatic ferments of infants. For this study the duodenal catheter was employed and pancreatic juice was obtained for examination directly from the duodenum. It was therefore not necessary to have recourse to the previous indirect methods, such as tests of stools or extracts of the pancreas. A large number of cases were examined by this method; the report including normal infants of various ages, as well as sick infants suffering from pylorospasm and from malnutrition. It seems unnecessary to review the results obtained. For the present purpose, it is sufficient to repeat, that the three pancreatic ferments investigated, namely, trypsin, amylase and lipase, were found almost constantly present even in advanced cases of marasmus (atrophy, decomposition).
The large series of cases of the first report did not include any examination made on infants suffering from acute disturbances.
