Two patients with chemical pneumonitis secondary to inhalation of an epoxy curing material used in the coating of pipes had similar patterns of cough, hemoptysis, and dyspnea associated with diffuse bilateral alveolar infiltrates shortly following the exposure. Pulmonary function studies showed a volume-restrictive defect with severe hypoxemia, but an elevated diffusing capacity. All lung function studies returned toward normal within 1 month of exposure. One patient underwent an open lung biopsy which showed changes consistent with a nonspecific injury to the alveolar wall. This epoxy curing material, trimellitic anhydride, represents another cause of diffuse lung injury that can result in pulmonary edema.

Septicemic disease occurred in 49 of 126 pigs several days after being transported 80 km. All affected pigs died. The main changes in acutely affected pigs were skin discoloration, pulmonary edema, arthritis, meningitis, and renal glomerular thrombosis. In peracute cases, gross findings were minimal. Haemophilus parasuis was isolated from multiple organ sites in most affected pigs. Haemophilus parasuis was isolated from nasal swab specimens from 17 of 20 clinically normal pigs on the farm of origin. Fatal acute septicemia was reproduced in 2 pigs by intravenous or intratracheal exposure to an isolant of H parasuis obtained from 1 of of the 49 fatally affected pigs. Aerosol exposure of 5 pigs resulted in mild pneumonia in 4 pigs and severe pneumonia, pleurisy, pericarditis, and terminal septicemia in 1 pig.

Routine measurement of pressure-volume curves of the lungs and thorax in seven patients treated with continuous mechanical ventilation provided supportive evidence for the presence or absence of cardiogenic pulmonary edema, noncardiogenic pulmonary edema, pneumonia, bronchospasm, mucous plugging, intubation of mainstem bronchus, atelectasis, and results of subsequent therapy. Those conditions associated with predominantly airway disease altered dynamic more than static pressure-volume measurements. Those conditions associated with parenchymal lung disease or loss of lung volume generally altered both dynamic and static pressure-volume measurements. The effectiveness of treatment of these diseases could be monitored by their effect on the pressure-volume curve. The determination of pressure-volume measurements are simple, noninvasive, and can be accomplished within minutes. The routine use of these measurements should be one of the monitoring procedures performed in patients treated with mechanical ventilation.

During all of 1974 we surveyed, for illnesses and deaths, about 407,000 yearling feedlot cattle. The morbidity was 5.1%, with a case mortality of 18.9% and a population mortality of 1.0%. Both morbidity and mortality were higher during fall and winter than during spring and summer. Of the 3,943 dead cattle, 1,988 were necropsied. The most prevalent diseases were: pneumonia, 48%; diphtheria, 6%; brisket disease, 6%; hemorrhagic colitis, 5%; riding injury, 4%; bloat, 3%; calculosis, 2%; endocarditis, 2%; abomasal ulcers, 2%; bovine viral diarrhea, 2%; embolic pulmonary aneurysm, 1%; and pulmonary edema, 1%.

Peptic aspiration pneumonitis (Mendelson's syndrome) results when gastric acid is aspirated into the lung, as may occur during anesthesia. In the present study, 0.1 N HCl was insufflated via the endotracheal tube into pentobarbital-anesthetized dogs in an amount sufficient to cause severe pulmonary damage. At death, the thorax was opened, the lungs grossly examined, and either weighed and desiccated for determination of wet/dry lung weight ratios, rinsed with saline for removal of alveolar surface phospholipids, or homogenized for whole lung phospholipid determination. Gross appearance and wet/dry lung weight ratios indicated severe pulmonary edema. The surface tension values of the lung wash were elevated over control values. Lysophophatidyl-choline (LPC) showed a striking increase over control values. Because LPC is a potent hemolytic agent which builds up in the lung following this pulmonary insult, and because increased hemorrhaging gradually develops following experimental acid insufflation, it is concluded that LPC is most probably causally related to the hemorrhagic pneumonia of Mendelson's syndrome.

The determination of effective dynamic and static relationships between pressure and volume aided in the diagnosis of pulmonary disease, its course, and the effects of therapy in 22 patients receiving continuous mechanical ventilation. These measurements were made on multiple occasions early in the course of mechanical ventilation and were repeated after any indication of clinical deterioration. Abrupt changes from control measurements provided supportive evidence for the presence of cardiogenic pulmonary edema in four patients, progressive pneumonia in four patients, bronchoconstriction in four patients, retained secretions in five patients, pneumothorax in two patients, intubation of main-stem bronchus in three patients, and atelectasis in two patients and were useful in evaluating the results of subsequent therapy. These determinations are simple, noninvasive, and can be accomplished within minutes. The equipment needed is the same as that needed for continuous mechanical ventilation.

We have successfully treated severe pulmonary edema of various etiologies and the concomitant hypoxia in 17 infants and children with continuous positive pressure spontaneous breathing. The pressure used was 8 to 14 cm of water above atmospheric pressure. No significant changes occurred in arterial or central venous blood pressure, and no patient developed clinical evidence of peripheral venous engorgement. Pulmonary edema cleared within 24 hours in all cases. We believe this rapid clearing may differentiate pulmonary edema from pneumonia and pulmonary hemorrhage. The pathophysiology and the roentgenologic findings are presented.

Drug-induced noncardiogenic pulmonary edema occurred in a previously patient receiving dextran 40. Dextran 40 should be considered another etiologic factor of drug-induced noncardiogenic pulmonary edema when this syndrome occurs in the absence of known precipitating causes such as shock, aspiration, and overwhelming pneumonia.

Twenty cases of methadone-induced pulmonary edema confirmed by clinical, laboratory and roentgenographic findings were extensively reviewed and the roentgenographic manifestations defined in terms of patterns, distribution, and duration of the process. Drug tolerance is a major factor in determining the severity of toxicity. Roentgenographic clearing in 48 hours or less, clinical improvement and pathogen-free sputum aspirates serve to differentiate edema from pneumonia.

Pulmonary veno-occlusive disease is a rare and usually fatal condition in which there is gradual obliteration of the pulmonary veins and venules. Without a lung biopsy the clinical diagnosis of this disease is difficult. If there is pulmonary hypertension with roentgenographic signs of pulmonary edema and of congestion in the absence of signs of increased left atrial pressure, the diagnosis must be considered. The morphologic picture of the lungs is characteristic. The small veins, and sometimes also the major veins, are narrowed or occluded by fibrous tissue, almost certainly on the basis of organized thrombi. Nodular areas of congestion, interstitial fibrosis, and pneumonitis are regularly present. A viral etiology has been suggested in a number of cases. If we may assume, however, that thrombosis of pulmonary veins is the initial event, the possibility has to be considered that this may be elicited by a virus in some patients and by toxic factors or by clotting disorders in others. Pulmonary veno-occlusive disease might then well be a syndrome rather than an etiologic entity.
