No sound was passed into the uterus for fear of setting up reflex action; the diagnosis of extrauterine gestation at about six and a half months with a living child was established without requiring to be clinched by proving the uterus empty. The patient was kept absolutely at rest in bed and the edema of the left leg cured by position.
According to the edema theory advanced by Fischer, glaucoma is "essentially an edema of the eyeball, and for its production we must hold responsible the same circumstances which are responsible for a state of edema in any other part of the body."
"The only change observed in these tissues is a reflex edema, excited apparently by pressure on the ciliary nerves and, probably, irritation of the vaso-motor fibers of the sympathetic." Lachrymal Gland. Hyper secretion due to reflex irritation. Cornea.
The atrophic type of scleroderma is preceded by an edema, and from pressure-atrophy of the fat and muscles the skin of the face is strained over the bones; the lips are shortened, the gums shrink from the teeth and lead to caries, and the nostrils are compressed. The etiology and pathology of this disease are quite obscure.
The edema of the brain, irregular pink mottlings of white substance, and an exudative lesion of one focus in the pia mater of the right side suggested an encephalitis more marked on the right side. Microscopically a few small vessels showed plugs of polynuclear leucocytes. The nerve cells were affected by various acute changes.
On the other hand, the ill effects of over-feeding and pruning may reach a point where the plant is seriously crippled. =Edema.= Under certain conditions plants in greenhouses or even in the open field, may absorb water through the roots faster than it can be transpired through the leaves, with the result that dropsical swellings or blisters occur on the leaves and more succulent stems.
At this stage the heart, which has already shown some trouble, becomes unable to force the blood properly against this enormous resistance of inelastic vessels and the blood pressure begins to fail as the left ventricle weakens. Edema, failing heart, perhaps aneurysms, peripheral obstruction, or hemorrhages are the final conditions in this chronic disease of arteriosclerosis.
It seems that both of these theories afford an explanation for many of the secondary pathological manifestations which characterize the intra-ocular tissues during a glaucomatous onset. Fischer criticizes the Henderson theory on the ground that increased blood pressure alone does not lead to edema edema is thwarted by high blood pressure.
Hirst, in an article on the difficulties in the diagnosis of pregnancy, gives several excellent photographs showing the close resemblance between several pathologic conditions and the normal distention of the abdomen in pregnancy. A woman who had several children fell sick with a chest-affection, followed by an edema.
Sometimes with serious edema and after serious hemorrhage the heart becomes very slow, unless some exertion is made, when it will beat more rapidly than normal. This probably represents a diminished cardiac nutrition. The cardiac lesions which cause a pulse to be slow are sclerosis or thrombosis of the coronary arteries, fatty degeneration of the myocardium, and Stokes-Adams disease.
