PNEUMONOKONIOSIS 



ous or catarrhal type P., Insular. Synonym of P., 

 Lobular. P., Intermittent. Synonym of P., Bilious. 

 P., Interstitial, Acute, inflammation of the intersti- 

 tial tissues of the lung, sometimes terminating in sup- 

 puration. P., Interstitial, Chronic, cirrhosis of the 

 lung ; a chronic inflammation of the lung, characterized 

 by an increase of the interstitial connective tissue. It 

 may be a termination of acute croupous pneumonia or 

 of pulmonary tuberculosis ; it may follow broncho- 

 pneumonia ; in some cases it is due to extension of a 

 chronic inflammation from the pleura, the so-called 

 pleurogenous interstitial pneumonia ; finally, pneumo- 

 nokoniosis is a form of interstitial pneumonia. Cirrhosis 

 of the lung is often associated with bronchiectasis. P., 

 Larval, a term given in epidemics of pneumonia to 

 those cases that present only some of the initial symp- 

 toms of the disease, slight chill, moderate fever, and 

 a few indefinite local signs. P., Latent, one in which 

 the physical signs are obscure or wanting. P., 

 Lobar. Synonym of P., Croupous. P., Lobular. 

 Synonym of Broncho pneumonia and P., Catarrhal. 

 P., Malarial. Synonym of P., Bilious. P. maligna. 

 Synonym of P., Septic. P. malleosa, pneumonia due 

 to the glanders-bacillus. It is a broncho-pneumonia 

 as a rule, but may assume a lobar form or manifest 

 itself as multiple abscesses. P., Massive, one in 

 which not only the air-cells, but the bronchi of an 

 entire lobe, or even of a lung, are rilled with the fibrin- 

 ous exudate. The auscultatory physical signs are 

 wanting; percussion yields an absolutely flat note. 



I The condition simulates pleurisy with effusion. P. 

 migrans, P., Migratory, a peculiar and well-recog- 

 nized form, involving one lobe after the other. It 

 seems occasionally to be in some way associated with 

 erysipelas. Synonym of P., Creeping, P., Wandering. 

 P., Necrotic, Goodhart's name for the non-tubercu- 

 lous variety of pulmonary disorganization sometimes 

 occurring in diabetic patients. The disease is charac- 

 terized by rounded patches at the apex or base of the 

 lung, the size of a hazel-nut or larger, in which a cavity 

 rapidly forms containing a central slough. P. notha. 

 Synonym of Capillary Bronchitis. P., Periodic. 

 Synonym of P., Bilious. P., Phreno-, pneumonia 

 associated with diaphragmitis. P., Plastic. Synonym 

 of P. , Croupous. P., Pleuritic. Synonym of Pleuro- 

 pneumonia. P., Pleurogenic, P., Pleurogenous, a 

 pneumonia secondary to disease of the pleura. P. 

 potatorum. Synonym of P. , Drunkards' . P. , Puru- 

 lent : this appears in three varieties: (i) the suppura- 

 tion may involve the surfaces of the minute bronchi 

 and air-vesicles — purulent catarrh ; (2) there may be 

 a true abscess of the lung ; (3) there may be a sup- 

 purative lymphangitis and perilymphangitis. The 

 causes of purulent pneumonia are : the aspiration of 

 matters containing pyogenic microorganisms — this pro- 

 ducing the first or second form ; an abscess may result 

 from the lodgment in the lung of a septic embolus, 

 derived often from a focus of purulent phlebitis ; 

 from traumatism ; from chronic diseases of the lung, 

 especially tuberculosis with cavity-formation ; from 

 extension of suppuration from neighboring organs, 

 as from empyema or hepatic abscess. P., Pytho- 

 genic, a contagious form rising under miasmatic 

 influences. P., Scrofulous, an old name for P., 

 Caseous Lobular. P., Secondary, that occurring as a 

 complication of some preexistent disease. P., Senile, 

 the broncho-pneumonia of the aged ; it may be due, 

 in part at least, to inability to expectorate the phlegm 

 that collects in the smaller bronchi. P., Septic, 

 a lobular pneumonia due to the inspiration of septic 

 material. It may also be caused by septic emboli. 

 In the new-born it is usually due to the aspiration of 



the maternal fluids during labor. P., Septinous, 

 P., Sewer-gas, a pneumonia following the inhalation 

 of sewer-gas. P. serosa, edema of the lungs. P., 

 Stripe [G. Streifenpneumonie], a pneumonia in 

 which the affected area has the form of a band or 

 stripe, usually running parallel with the spinal gutter. 

 P. , Syphilitic ; disease of the lung due to syphilis is 

 rare. Three forms are usually described — the pneu- 

 monia alba of the fetus (a. v.) ; the deposit of gum- 

 mata in the lung; and an interstitial pneumonia, 

 taking its origin at the root of the lung and passing 

 along the bronchi and vessels. French writers also 

 speak of an acute syphilitic phthisis, analogous to 

 acute pneumonic phthisis. P., Traumatic, pneu- 

 monia following injury of the lung ; also that consecu- 

 tive to section of the vagus nerves. P., Tuber- 

 culous, a lobular or lobar inflammation of the lung 

 due to the tubercle-bacillus. P., Tubular. Syn- 

 onym of Broncho-pneumonia. P., Typhoid, a 

 pneumonia with the symptoms of the typhoid state. It 

 is to be distinguished from Pneumo-typhus. P., 

 Vagus, that produced by section of the vagus nerves. 

 P., Wandering, a form of pneumonia in which 

 different portions of the lung present different stages 

 of the pneumonic process. It seems, according to 

 Guiteras, to be in some way associated with erysipelas. 

 P., White, a catarrhal form of pneumonia occurring in 

 a syphilitic fetus and resulting in death. By an over- 

 growth of epithelium in the air- vesicles the lung dies, 

 and fatty degeneration follows, giving the lungs a 

 dead-white appearance, with the imprint of the ribs 

 on their surface. 



Pneumonic (nu-tnon'-ik) [vvevfiuv, lung]. Pertaining
