A survey of primary infantile and juvenile pneumonia.

Statistical review The material for review was collected from the records of three Dublin Hospitals for the years 1937 to 1939. All patients dying within twentyfour hours of admission, or in whom signs of improvement had set in before starting treatment, were excluded. The cases were clinically divided into the two groups of lobar and atypical pneumonia. The former showed clinical evidence of lobar consolidation, the latter consolidation of an irregular patchy nature. Eight hundred and ninety-five cases were studied. Table 1 shows the age group distribution, and table 2 the combined fatality rates for the three years studied. TABLE 1
