Studies on Epidemic Influenza: Comprising Clinical and Laboratory Investigations

The question of the value of wearing a gauze mask over the mouth and nostrils during an influenza epidemic is still an open one. Masks, however, have been found useful in protec...

We worked purely on the hypothesis that those individuals recovering from a mild or moderate influenza infection developed a higher grade of immunity than those in whom the dise...

The second group, or those showing a leucopenia throughout their course, was by no means an unusual thing. This is a cardinal point—in fact, one of the most striking clinical fe...

When the sample was removed for standardization it contained not only a thick suspension of Pfeiffer bacilli, but also bits of agar and blood-stained debris. It was necessary to...

It will be impossible to review the numerous reports on the recent epidemic that have appeared. Many of these can be discounted, as far as the finding of B. influenzæ is concern...

In a recent article published by Loy McAfee (J. A. M. A., 1917, 72, 445) he discussed the confusion which existed between the diagnosis of cerebro-spinal meningitis and epidemic...

In a communication from Columbia University it is stated that the epidemic appeared during the week beginning September 22. No records were available for the student body at the...

For the estimation of the time elapsing between the onset of the pneumonia and death we are dependent upon the clinician. This is often quite difficult to do, in as much as with...

Before referring to the physical signs it might be well to describe the condition and general appearance of the patient when the lungs became involved. The patient who had been...

Most of the vaccine was distributed within a radius of 200 miles of Rochester, Minn., but samples were furnished to physicians all over the country, who agreed to return statist...

A considerable discussion has arisen concerning the proper nomenclature for the pneumonia or pneumonias found in epidemic influenza. From some quarters have come the reports of...

One of the best descriptions of that epidemic was given by Dr. O. Leichtenstern in Nothnagel’s Encyclopedia of Practical Medicine. This contribution, among many others, describi...

When a sufficiently large dose of vaccine is given to an individual there is usually a transient rise in temperature for from 12 to 48 hours; the local focus of injection become...

Too much stress cannot be placed upon the importance of the lymphatics in all forms of pneumonia. They play an important role in the drainage of the lung during inflammation. In...

Various other methods have been used to bring about this beneficial change in hemoglobin. Gioelli (1896) used a medium made up of 1.1 per cent. hemoglobin and 21.5 per cent. mal...

More or less cloudy swelling or granular degeneration of the muscle elements of the heart was not uncommon. It was sufficiently pronounced in 12 cases to be readily detected by...

We very soon recognized in consultation with the obstetricians that the pregnant woman was in a really dangerous condition if she contracted influenza. She was likely to have a...

Thorough enforcement of ordinances requiring the reporting of all cases and all deaths as now demanded by public health rulings should be insisted upon. These reports are so imp...

It is during this early phase of the reaction that the influenza bacilli can be shown within the lung structures. The distribution of bacteria is not uniform. Clusters of these...

Swabs from the nasopharynx were cultured from 31 individuals; nearly all of these were cases suspected of diphtheria or as carrying the diphtheria bacillus, and no particular ef...
