Patch testing with methyldibromoglutaronitrile
American Journal of Contact Dermatitis, 2000The combination of methyldibromoglutaronitrile (MDBGN) and phenoxyethanol (PE) is widely used as a preservative in body care products. Sensitization rates to MDBGN have increased parallel to its increasing use in cosmetics, skin care products, and moist toilet paper since the early 1990s, whereas PE is obviously not a sensitizer.

SIAM Journal on Numerical Analysis, 1979
The paper establishes the basic convergence conditions for the method of nonconforming finite elements applied to a class of generalized elliptic boundary value problems with variable, not necessarily smooth coefficients. The main result is a new, generalized patch test. Approximability and success in this test is the necessary and sufficient condition

Patch Testing Methodology [PDF]
, 2009 Jozef Jadassohn is the father of patch testing. At the time of his discovery in 1895, he was Professor of Dermatology at Breslau University (now Wroclaw in Poland). He initially reported a patient who had developed an eczematous reaction to mercury plasters.

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

Mesh‐distortion immunity assessment of QUAD8 elements by strong‐form patch tests
, 2006Strong-form patch tests are conducted to assess the mesh-distortion immunity of three types of 8-noded plane quadrilateral elements. Patches with various types of mesh-distortions are considered for the purpose.

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 ...

In situ immunological characterization of the infiltrating cells in positive patch tests.
British Journal of Dermatology, 1984Skin biopsies from positive allergic patch tests were analysed by immunoenzymatic labelling of frozen sections with monoclonal antibodies. In seventeen patients the cellular infiltrate consisted of T cells admixed with Langerhans cells/indeterminate ...

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.
