Elderly man with two soft hyperpigmented nodules on the forehead

Shi'ite Muslim

• Children with chronic swellings at the center of the forehead may be headbangers. [101]
• Children with acrodynia characteristically assume an Islamic-prayer-like position that has been called the "Salaam position," but this is also a misnomer as explained in the erratum above. Acrodynia is a rare manifestation of childhood mercury poisoning. [102]
• Recent case of a 4 year old boy with acrodynia, the result of inhaling mercury vapors from the 17 gallons of latex paint drying on the walls of his home. The paint had 3 times the allowable amount of mercury. [103]
• Practitioners of the Christian faiths may also bear physical consequences of prayer. "Clergyman's knee" is an infrapatellar bursitis (similar to housemaid's knee) and "genu genuflectorum" is a noninflammatory knee effusion resulting from chronic stress of the lateral meniscus. [104]
