Cardiovascular Manifestations of Epidemic Dropsy and Their Treatment.

Abstract: D.urtng the latter half of last year a large number of ease? of epidemic dropsy came under our observation. The majority of these were admitted under one of us (R. N. C.) at the Carmichael Hospital for Tropical Diseases and some under the other (U. P. B.) at the Calcutta Medical College and Calcutta Medical School hospitals. In most of these cases cardiovascular derangements were the prominent feature. The cardiac aspect of cases admitted into the Tropical Diseases Hospital was jointly studied by both of us and in these, besides the usual critical physical examination, special methods of investigation such as orthodiagrams and electrocardiograms were employed. In the following table we have given all the important findings regarding 19 of these cases. A careful analysis of the symptomatology shows that the chief symptoms complained of by these patients were ccdema of the legs, which appeared very early, and in some cases was followed by generalised anasarca, diarrhoea, fever,

The Value of the Antimony Test in the Diagnosis of Kala-Azar. Part II. The Finger Prick Blood Test.

Abstract: Introduction.?From the time of the discovery ?f the antimony test for the diagnosis of kala-azar (1927) the great sensitiveness of the reaction was appreciated by its originators. They found that ^e reaction was obtained in fairly high dilutions the serum and quite apparent and definite premutation was obtained in dilutions of 1 in 10 *? 1 in 20. Chopra, Gupta and Basu (1927) described a simple test for the diagnosis of kalaazar which could be performed with a drop of blood, obtained from a finger pricked with a needle, and diluted with a solution of potassium ?*alate. Although the series of cases of both kalaazar and controls on which this test was tried v|\"ere small, these workers came to the conclusion ^at the results obtained with this simple test ran Poetically parallel with those obtained with the serum test and that the reaction had great possiuities in giving a simple, rapid and economical est for the diagnosis of kala-azar. Napier (1929) carried out a series of observa'ons with the finger prick test in the Out-patient Pepartment of the Calcutta School of Tropical j;ledicine and Hygiene but did not obtain satisactory results. The present authors, therefore, Very carefully went into the details of^ the test Jjpd carried out a large series of observations with Jfferent dilutions of the blood and the reagent, the diluted blood with corpuscles in suspension and without. It is unnecessary to describe the details of this work here and we will confine our-
