Types. Tuberculous meningitis is the most frequent type as 

 a rule ; yet our record shows 22 cases of suppurative, 16 of tuber- 

 culous, and 3 of hemorrhagic pachymeningitis and 1 of chronic 

 leptomeningitis. 



The diagnosis of suppurative meningitis has been made many 

 times upon the gross pathological lesions and was found in infants 

 of less than 1 year, except in one instance, and also up to the 

 second year, except in three cases. This finding is in accord with 

 Zappert. (55) 



Associated pathological lesions. All the cases of tuberculous 

 meningitis were the result of an extension of a generalized miliary 

 tuberculosis, except two, which were associated with pulmonary 

 and glandular tuberculosis. 



The suppurative form was associated with bronchopneumonia 

 in 6 cases ; in 2 with lobar pneumonia, and in 6 with otitis media ; 

 2 of these were hemorrhagic. The rest had no other recorded 

 marked lesion. 



TYPHOID FEVER 



Although typhoid fever is met with great frequency in adults 

 in Manila, yet this series shows only 3 cases. The youngest is 

 a male infant, 7 months and 20 days old, that had swollen Pe- 

 yer's patches in the upper part of the ileum; these became pro- 

 nounced, larger, hemorrhagic, and ulcerated as one approached 

 the ileocsecal valve. The solitary lymph follicles were not in- 

 volved. The spleen was enlarged and soft with increased splenic 

 tissue. The second is a 1-year-old female that had broncho- 

 pneumonia, swollen Peyer's patches, enlarged and soft glands, 

 and hyperplasia of the solitary lymph follicles. The intestinal 

 contents were watery and yellowish. The spleen was enlarged, 

 dark colored, and soft. The third is a 5-year-old male with 

 mesenteric lymphadenitis and swollen Peyer's patches. 



From this we see the infrequency of typhoid in children below 

 5 years of age, although Rogers (44) speaks of its frequency in 

 children of India. Domingo (H) found no case under 2 years
