History
The usage of terminology for types of goiter has varied over the past century. Physicians and surgeons tend to differentiate among solitary-nodule goiter, multinodular goiter, and non-nodular goiter more thoroughly in recent decades than they formerly did. Thus some sources have described, or still describe, thyroid adenoma (toxic adenoma) as synonymous with toxic multinodular goiter, but other sources differentiate those two as single-nodule disease versus multinodular disease (respectively) with pathogenesis that is likely differing in most cases (e.g., single neoplastic cell clone versus multifocal or diffuse molecular metabolic change). The medical eponyms "Plummer disease" (named after American physician Henry Stanley Plummer) and "Parry disease" (named after English physician Caleb Hillier Parry) have been used to refer to toxic multinodular goiter, toxic adenoma, and toxic diffuse goiter (Graves disease); the specific entity in each patient/case is not always clear retrospectively, especially in older literature. This is logical given that advanced medical imaging that can show what is happening at various places within a thyroid gland inside a living person (such as nuclear medicine imaging of radioiodine tracer uptake) was not available until after the 1940s.

BC Powder has historically been most commonly associated with relief of headaches. Many users of the brand erroneously believe the name of the product to be "BC Headache Powder." Recent advertising and marketing endeavors by the company suggest that it is eager to associate itself with relief of general bodily aches and pains as well. Goodys Powder, like BC, is also distributed by Prestige Brands. For many years, singer and actor Faron Young was the celebrity featured on many of the products television and radio commercials. For several years, BCs television and radio commercials have featured real-life users of the product, non-actors who are encouraged to submit their stories to BC Powder through contests announced on radio programs. Recently, most entries have been culled from listeners of the Charlotte, NC-based radio program The Big Show with John Boy and Billy. In recent years, members of the Tom Joyner Radio Shows audience have appeared in BC commercials after hearing of the promotion on that program, or from promotions held on Joyners annual "Fantastic Voyage" fantasy cruise. BC Powder also distributes and markets BC Cherry and BC Arthritis Formula. In a deal which took effect in 2012, GlaxoSmithKline (GSK) sold BC Powder and 16 other brands to Prestige Brands. References
