Página 64 - At the end of about 16 hours following this application 5 of the characteristic lesions appeared on the area to which the mites had been applied. We established, therefore, that the minute mite which we fished out of the straw siftings was the factor in the straw that was responsible for the production of the eruption. This mite was identified for us by Mr. Nathan Banks, expert in acarina of the United States Bureau of Entomology, as very close to, if not- identical with, Pediculmdes ventricosus.
Página 65 - The central vesicle is usually minute, not exceeding a pin head in size; in other cases it may be larger, acquiring the dimensions of a lentil seed or pea. The eruption is more or less profuse and usually extends over the neck, chest, abdomen, and back, and in a lesser degree over the arms and thighs. Scattered lesions are often observed on the face, forearms, and legs, but the hands and feet are nearly always free. The extent of the eruption and the size of the individual lesions are apt to bear...

First we exposed for an hour the second portion of the siftings in a Petri dish to the vapour of chloroform under a bell jar with a view to killing any insect or acarine that might be present. These siftings were tnen applied to the right axilla of the volunteer to whose left axilla the untreated siftings were applied.
Página 65 - The disease is characterized, as a rule, by an eruption consisting of wheals, nearly all of which are surmounted by a central vesicle, which very rapidly acquires turbid and later pustular contents. This is the peculiar and characteristic lesion of the affection. Instead of frank wheals, the primary efflorescences may be erythemato-urticarial spots or papulo-urticarial lesions. They vary in size from a lentil seed to a finger nail, and are rounded, oval, or irregular in shape. They are of a warm...
Página 64 - At the end of about 16 hours the characteristic itching eruption appeared. Later three volunteers slept upon a mattress during a night and each one developed the eruption at the end of about the same period. We next took some of the straw and sifted such particles as would pass through the meshes of a fine flour sieve. The sifted particles were divided into two portions and placed in two clean glass Petri dishes. One of these was then applied for one hour to the left axilla of a volunteer. At the...
Página 65 - In 3 instances transient albuminuria was observed. The affection is apt to be confounded with ordinary "hives" or urticaria, chickenpox, and scabies. We have known many such errors of diagnosis to have been made. In one case with a particularly profuse eruption, the patient was under suspicion of suffering from smallpox. We have received a number of letters from laymen and physicians in Pennsylvania and Ohio alleging that...
Página 67 - Jede tierische Zelle ist ihrem Wesen nach doppelkernig: sie enthält einen somatischen und einen propagatorischen Kern. Ersterer steht den somatischen Funktionen, Stoffwechsel und Bewegung vor und kann vorherrschend Stoffwechselkern oder Bewegungskern sein. Der propagatorische Kern enthält vor allem die Vererbungssubstanzen, denen auch die Fähigkeit zukommt, einen neuen Stoffwechselkern zu erzeugen.
Página 65 - Association in June, 1909. Prominent dermatologists from Boston, Baltimore, New York, Chicago, St. Louis, San Francisco and London stated that they were unfamiliar with the clinical picture presented. Eruption. — The disease is characterized, as a rule, by an eruption consisting of wheals, nearly all of which are surmounted by a central vesicle which very rapidly acquires turbid and later pustular contents. This is the peculiar and characteristic lesion of the affection. Instead of frank wheals,...

In order to establish the etiological role of the straw mattresses experimentally, one of us exposed his (left) bare arm and shoulder for one hour between two straw mattresses. At the end of about sixteen hours the characteristic itching eruption appeared. Later three volunteers slept upon a mattress during a night and each one developed the eruption at the end of about the same period. We next took some of the straw and sifted such particles as would pass through...
Página 65 - The eruption is accompanied in well-pronounced cases 'by the most intolerable itching, which for obvious reasons is worse at night and may seriously interfere with sleep. The pruritus may lead to violent scratching with the production of excoriations. Systemic Symptoms. — Some patients with profuse eruptions have an elevation of temperature varying from 99° F. to 102
