Importance of associated viral and bacterial infections in the production of acute pneumonias.

Bacteriologic and virologic investigations carried out in a group of 85 patients with acute pneumonia have allowed the determination of the etiologic agent in 52.9% of the cases. Of these, 40% showed combined viral and bacterial infections. Mixovirus infections were frequently associated with staphylococcic ones (7 out of 8 cases) and adenovirus infections with the pneumococcic ones (6 out of 7 cases). The most severe and longdrawn clinical pictures with frequent pleuropulmonary complications (in 22.24% of the cases) had a biphasic evolution in only 6 of the 18 pneumonias of mixed etiology. For their high frequency and their clinical peculiarities, mixed etiology pneumonias might be considered as distinct clinical entities.

The role of some viruses in acute pneumonias in adults.

Virological and bacteriological investigations were performed in 85 patients with acute pneumonias and virus isolation or serological evidence of virus infection were obtained in 37.6% of the cases. Influenza A2 and B viruses were incriminated in 14.1% of the patients; parainfluenza viruses in 7% and adenoviruses in 17.2% of the cases. Coxsackie virus was isolated from one patient's blood, and poliovirus 3 was recovered in 3 cases. In 5 cases associated virus infections were detected.

Value of systolic time intervals in the estimation of heart failure secondary to acute myocardial infarction.

Serial measurements of left ventricular systolic time intervals (STI) were carried out in 44 patients with acute myocardial infarction (AMI) in the first 5 days after onset, by indirect methods. The patients with heart failure showed significant decreases of ejection time (ET) (p less than 0.001) and of the ejection time index (p less than 0.005) and increases of Wiessler's ratio (PEP/ET) (p less than 0.001). The pre-ejection period (PEP), the isovolumetric contraction time and the total electromechanical systole were unsignificantly changed. Ejection time was shorter than 250 msec in the patients with acute pulmonary edema or congestive heart failure, in most of the patients with flutter or atrial fibrillation and in 16 of the 17 patients who died. Ejection time may have a prognostic significance and may be useful in the early detection of heart failure in AMI. The changes of STI after administration of lanatosid C show the positive inotropic effect of this drug in patients with AMI.

Electrocardiographic diagnosis of myocardial infarction in patients with pacemakers.

The ECG changes of myocardial infarction during permanent or transient right ventricular pacing were studied in 32 patients with transvenous pacemakers who developed myocardial infarction. During right ventricular pacing the electrocardiogram resembled left bundle branch block in 29 patients, right bundle branch block in two, and in one patient the pattern could not be determined. Myocardial infarction induced new ECG changes during pacemaker rhythm in 20 of the 32 patients. There were only QS complexes in 5 cases, ST segment abnormalities in 4 and T wave inversions in 4, negative Q and T waves were simultaneously observed in one patient, Q wave and S-T segment changes in 3 and S-T segment change and T wave inversion in 3 patients. It is concluded that knowledge of the ECG changes induced by myocardial infarction in most patients under artificial pacing can be useful for diagnosis.
