Davenport of the 17th and others
A RESOLUTION
Recognizing the work of German dermatologist Josef Jadassohn who invented the innovative
patch-testing medical technique in 1895 and encouraging medical practitioners to consider
applying patch-testing for patients with a clinical history of metal hypersensitivity prior to
certain implantation operations; and for other purposes.
WHEREAS, most implants used in orthopedic operations are composed of metal alloys that
contain common contact allergens, such as nickel, cobalt, and chromium; and
WHEREAS, more than 1 million lower extremity total joint replacements are completed
yearly in the United States and are expected to increase in the coming years; and
WHEREAS, allergic complications to metal implants often cause problems such as chronic
joint pain, dermatitis, and joint failure; and
WHEREAS, nickel is commonly used in alloys due to its strength and durability; and
WHEREAS, many cases of metal hypersensitivity are due to contact with alloys containing
nickel; and
WHEREAS, surgeons and dermatologists commonly rely on patch-testing to evaluate
patients for potential metal allergy; and
WHEREAS, the value of patch-testing for patients with a clinical history of metal
hypersensitivity before implants are placed into bones or joints has been acknowledged by
research published in JAMA Dermatology, a journal of the American Medical Association.
NOW, THEREFORE, BE IT RESOLVED BY THE SENATE that the members of this body
recognize the memory and contributions of medical pioneer Josef Jadassohn and encourage
medical practitioners to consider applying patch-testing when evaluating patients with a
clinical history of metal hypersensitivity prior to certain implantation operations.
BE IT FURTHER RESOLVED that surgeons and dermatologists are encouraged to work
together to establish guidelines to identify patients who would benefit from replacements of
previously implanted contact allergens.
BE IT FURTHER RESOLVED that the Secretary of the Senate is authorized and directed
to make copies of this resolution available for distribution to the public and the press.
