Erythema Component of the Tuberculin Reaction

Erythema Component of the Tuberculin Reaction.

THE development of erythema is often a striking feature of the reaction to tuberculin. It occurs in the cutaneous test of Von Pirquet, and its development was the criterion of positivity in the conjunctival test of Wolff-Eisner and Calmette. It is usually well developed in the test which superseded both of these, the intracutaneous test of Mantoux. Over the years, however, particularly with the...

The Intradermal Tuberculin Reaction

The special interest of this paper centres around diseases of bones and joints and particularly the early diagnosis of tuberculosis of the hip joint. Tuberculosis of the hip presents a difficult problem; if the diagnosis is only made on definite text-book signs much valuable time may be wasted, yet if a provisional diagnosis is made early in the disease somenon-tuberculous conditions will be in...

Stability of Tuberculin Reaction.

P ERIODIC REPORTS HAVE EMPHASIZED the lack of stability of repeated tuberCulin skin tests in children. Kunofsky and Katz1 reported on two large groups in two schools for mental defectives. Reversion rates of 4 to 19 per cent were found. Marks et al.2 reported reversion rates between 12 and 26 per cent, depending on Criteria used, during a one-year period of observation of 1,100 tuberculin posit...

Cellular Aspects of the Tuberculin Reaction.

The Ophthalmo-tuberculin Reaction in Cattle

THE CONCLUSIONS TO BE DEDUCED FROM THIS BRIEF SERIES OF EXPERIMENTS ARE AS FOLLOWS: 1. The ophthalmo-tuberculin reaction is of some value for diagnosis of tuberculosis in cattle. A characteristic conjunctivitis with fibrinous exudation coming on from six to eight hours, reaching a maximum in from sixteen to twenty-four hours and disappearing in forty-eight hours, is noted in tubercular animals....
