Summary We tried to simulate the Vollmer patch test in the field of coccidioidomycosis with a patch test made with coccidioidin material. Out of 120 subjects tested with the filter paper method similar to that of Vollmer's, twenty-seven positive patch tests were noted, or 22.5 per cent. With the ointment method, four positive patches out of 100 known

The limitations of the patch test
International Journal for Numerical Methods in Engineering, 1980AbstractA simple approximation by nonconforming finite elements is presented that passes the patch test of Irons and Strang but does not yield approximate solutions converging to the solution of the given boundary value problem. It is constructed from continuous piecewise linear functions perturbed by step functions.

Routine path testing with a series of 6 industrial biocides containing methylene‐bis‐thiocyanate (Cytoc 3522®), benzosothizolin‐3‐one (BIT), chlorocresol (Preventol CMK®), 2‐n‐octyl‐4‐isothiazolin‐3‐one (Kathon 863®), polyhdroxymethylene monobenzylether (Preventol D2®) or 1,3,5‐tris (hydroxy‐ethyl) hexahydrotrizine (Grotan BK®) was carried out in 6 ...

Contact Dermatitis, 1984
Colophony (rosin) has been fractionated into 2 parts, an acidic and a neutral fraction. Routine patch testing with neutral components gives positive reactions at a 40% higher frequency than routine patch testing with colophony (20%) (w/w in pet.). A concentration of 60% colophony is suggested for routine patch testing.

Patch testing—a recapitulation
Journal of the American Academy of Dermatology, 1981Although patch testing continues to be one of the most useful office tools of the inquiring dermatologist, the procedure is not used as often as patients deserve. This article reviews the use of the patch test and emphasizes its utility in the practice of dermatology.

Reproducibility of patch tests
Journal of the American Academy of Dermatology, 1989Patch tests with a series of 39 substances were performed in 41 patients on one side of the upper aspect of the back. Testing was repeated on the contralateral side of the back 1 week later (sequential testing). In 35 other patients, duplicate patch test series were simultaneously applied on both sides of the back (concomitant testing).

AN ATTEMPT was made to develop a histoplasmin patch test similar to the tuberculin patch test. Since many analogies exist between histoplasmosis and tuberculosis, such a test was expected to be practicable. Histoplasmin patch tests were prepared in the following way: 16 square centimeters of thin filter paper was saturated with a solution consisting ...

Bioengineering and the patch test
Contact Dermatitis, 1988Several non‐invasive techniques based on different physical principles have been developed to investigate skin function and have been used for patch test assessment. In the present paper, the advantages and the defects of these methods are described in the light of the more recent data available in literature.

Abstract Living plants and natural plant products, such as balsams, turpentines, and the aroma chemicals found in perfumes and in flavorings, are among the most common causes of contact dermatitis. Most of the dermatitis-producing plants belong to a limited number of plant families, and many of the plant sensitizers that have been isolated belong to ...
