Corrosion of Amalgam Surface Due to Contact with Gold

Hyperpigmentation of back of hands due to Phytophotodermatitis secondary to contact with Citrus fruits juice

Background and objective: Peel oil and juice of citrus fruits have furocoumarin (Psoralen) that can induce phytophotodermatitis. If the reaction is mild, then only hyperpigmentation (Without itching, burning, erythema, vesicle and bullae, formation) may occur. The objective of this study was to describe the patients with hyperpigmentation of back of the hands. Materials and Methods: Thirty-two ...

Mercury toxicity due to the smelting of placer gold recovered by mercury amalgam.

A 19-year-old man developed tremor in both hands and fatigue after starting work at a placer gold mine where he was exposed to mercury-gold amalgam. Examination revealed an intention tremor, dysdiadochokinesis and mild rigidity. The 24-h urinary mercury concentration reached a peak of 715 nmol/l (143 ug/l) shortly before the clinical examination, after which he was removed from working in the g...

Systemic contact dermatitis due to corrosion of titanium-coated nickel and cobalt bone plate fixation

RATIONALE Corrosion refers to the degradation of a material that occurs following its interaction with other substances in the environment. Corrosion of metallic substances into tissues may lead to inflammatory responses such as systemic contact dermatitis (SCD), a skin condition where an individual who has previously been sensitized to a particular allergen via the cutaneous route will subsequ...
