xn, B, 2 Mendoza-Guazon: Anatomicopathologic Lesions 79 



lobe was affected four times and the lower only once. Combined 

 lesions: The right upper lobe has the most varied combina- 

 tions — with the left lower lobe twice, with the right middle 

 three times, and with the posterior of the right lower lobe and 

 with the right lower lobe once each. The lower lobes and the 

 right middle were involved only once. As we see, the right 

 middle lobe was not singly affected, but only as an extension 

 from the other lobes of the same side. 



Our order of frequency is: Left lower lobe thirteen times; 

 right apex, ten times; right base, five times; left apex and the 

 middle, three times per extensionem. This corresponds with 

 that of Holt. (27) 



Freer (16) gives this order of frequency — upper lobes are af- 

 fected as frequently as the lower: More frequently the right 

 upper and the lower left, the former at least twice as often as 

 the right lower; quite frequently also the middle lobe; not un- 

 commonly both lungs involved. During the first years of life, 

 the upper lobes are more often attacked. 



Associated lesions. There were 13 cases with serofibrinous 

 pleurisy, 1 with suppurative pericarditis, and 1 with empysema. 

 It was associated with some form of gastrointestinal trouble in 

 15 cases, of Asiatic cholera in 4 cases. One had diphtheria, and 

 in another there was found thrombosis of the longitudinal and 

 lateral sinuses of the head. Five cases had also bronchopneumo- 

 nia. 3 meningitis, 1 empysema, and 1 otitis media. The records 

 of 4 cases show hypertrophy and dilatation of the heart, 2 of 

 them being clinically diagnosed as infantile beriberi. 



One case had bronchiectic abscesses and suppurative anterior 

 mediastinitis with noma. Two cases had empysema in the same 

 side as the pneumonic lobe, which was the left lower. 



MENINGITIS 



Meningitis has been a favorite clinical diagnosis in cases dying 

 of convulsion, for frequently the physician is only summoned 

 to see the infant in his last hours, or because many of the diseases 

 of these young beings have a hidden and rapid course. 



Our record shows 42 cases, the male sex surpassing the female 

 in number, there being 25 of the former and 17 of the latter. 

 The age incidence shows that even the very young can be affect- 

 ed. The youngest is a 5-day-old female with sacral spina bifida, 

 and the next is another female with ectopia vesicae, that lived 

 for eight days.
