The oesophagoscope, however, has been successfully employed for diagnostic purposes.
The presence of fragments of the cancer in the contents removed by washing out the stomach with the stomach-tube has been observed by Rosenbach in three cases of gastric cancer, and utilized for diagnostic purposes.

The other diagnostic relations of jaundice are more properly considered in connection with the malady of which jaundice is a symptom.
The detection of fragments of cancer in the vomit or in washings from the stomach is of equal diagnostic significance, but of rare applicability.
The thrombosis is the result of marasmus, and therefore may occur in other gastric diseases besides gastric cancer, so that this symptom has not all the diagnostic importance for gastric cancer claimed by Trousseau.
Footnote 101: "The Diagnostic Value of Uncontrollable Vomiting," by W.
The diagnosticsymptoms are epigastric pain, vomiting, and gastric hemorrhage.
This persistence of the latter renders it, as has been stated, a valuable diagnostic sign.
Footnote 66: This is now known to be an unreliable distinction, expressing perhaps a general rule, but one with so many exceptions as to render it void of diagnostic significance.
The presence of blood in matters regurgitated or vomited forms the chief diagnostic indication of ulceration of the oesophagus, taken in connection with the usual symptoms of acute or chronic oesophagitis.
They even suggested, for diagnostic purposes, what seems to us the rather dangerous procedure that the patient should hold his mouth and nostrils tight shut and blow strongly.
Tapping may be needed as a diagnostic aid, and in such circumstances as much fluid as can be removed should be evacuated with the same precautions as mentioned in the last paragraph.
Case 159] The cases which presented the most serious diagnostic difficulty in this relation were those in which the wound was situated in the thicker muscular portions of the lower part of the abdominal and pelvic walls.
Their infrequency depended on the difficulty of striking the body in such a plane as to implicate the belly wall alone, and their interest in the diagnostic difficulty which they gave rise to.
This case was of much interest from the diagnostic point of view.
The only diagnostic point which it is necessary to consider in this chapter is the determination of the nature of the bullet which has caused the particular injury under observation, and this is more a matter of interest than importance.

Intralaryngeal medication and surgery soon followed the discovery of the diagnostic properties, and its principles were extended to the elucidation and treatment of diseases of the parts situated between the nose and throat.
Tuerck continued his experiments for a time; and it was in this year, 1857, that the instrument was actually used for the first time for diagnostic purposes.
Alkalies, or organic salts of alkaline metals, when taken as medicine render the urine alkaline, and the indication is then not of much moment; but if none of these causes exist, the condition is of serious diagnostic import.

As a diagnostic this mixture of the two is said to be far superior to either cocaine or morphia alone.
It has some diagnostic significance and should be borne in mind where a decreased excretion of urine is reported.
This is the cardinal diagnostic error in adult as well as in infantile scurvy--time and again, and in spite of urgent and repeated warnings, patients continue to be treated for rheumatism.
These diagnostic points should be constantly remembered in relation to the discussion which follows, and will not be reiterated in the differentiation of scurvy from the various other diseases.
A sign of great interest, although not of diagnostic importance, is the "beading" of the ribs noted by many observers, and emphasized by Jackson and Moore.
The two diagnostic signs, however, are the hemorrhages about the joints and the loosening of the teeth.
This report is interesting, not so much from a diagnostic standpoint as because "contrary to what might have been expected, scorbutic cases when operated upon showed no particular tendency to hemorrhage.
Its diagnostic value has been greatly exaggerated, as it is frequently not present when the disease is advanced (observe radiographs illustrating separation of the epiphyses).
It is only when these herniae occur at the situations commonly described, and where they manifest their broadest contrast, that the following diagnostic signs can be observed.
The value of the manner of speech, as diagnostic of character, was exemplified not long since at Messrs.

It is needful here to emphasise this hundred-fold repeated experience with special distinctness, for some recent authors do not even yet allow the full diagnostic importance of the blood examination.
At the time when Ehrlich formulated his proposition on the diagnostic importance of the eosinophil cells in leukæmia, the simple eosinophil leucocytosis (see p.
No one surely would deny the diagnostic value of glycosuria for diabetes, because in conditions of inanition, for instance, the sugar of a diabetic may completely vanish, although the disease continues.
The well-known work of Müller and Rieder has more particularly given rise to this opposition, and thrown doubt on the diagnostic importance of the eosinophil cells.
They are perhaps of greater diagnostic value than the eosinophils, because up to the present time we know of no other condition (in contradistinction to eosinophil leucocytosis) in which a marked increase of the mast cells occurs.
It does not seem superfluous in this place expressly to emphasise, that what has been said on the diagnostic importance of the megaloblasts only holds for the blood of adults.
In favour of the diagnostic value of the absolute increase of the eosinophil cells are those cases too, where with a blood condition closely recalling leukæmia, the absence of eosinophil cells excludes the diagnosis of that disease.
A blue line on the margin of the gums, the last symptom, is regarded as diagnostic and its presence as conclusive evidence of the nature of the disorder.
Another diagnostic symptom of value is that in traumatic pericarditis respiration is painful, not difficult, and the respiratory rate is very much increased on movement.

The white rump of the former is diagnostic and is easily seen in flight, but is generally covered by the wings when the birds are running on the sand.
Its flight note is an emphatic near-whistled chu or chru, resembling some of the calls of the pectoral and semipalmated sandpipers, but quite diagnostic when one is sufficiently familiar with it.
Mr. Nichols says in his notes: This bird is a size larger than least or semipalmated sandpipers, and at favorable angles shows a diagnostic white patch crossing above the rather dark tail.

He added that medicine owed as much to Auenbrugger for his rational method of treating effusions into the pleural cavity, whether of pus or serum, as for his diagnostic sign by which the presence of the fluid could surely be recognized.
He talks of Auenbrugger's new diagnostic method as if it were an imitation of Hippocrates's succussion method of recognizing the presence of fluid in the chest by shaking the patient till the liquid gave the characteristic splash.
More than this, it will never be merely an historical reminiscence, because of the fact that it guided men aright, but it will in its actuality remain as an aid and diagnostic auxiliary.
