A multiple myeloma that progressed as type I cryoglobulinemia with skin ulcers and foot necrosis: A case report.

Rationale: Type I cryoglobulinemia is a rare and life-threatening condition. It occurs mainly in B-cell lymphoproliferative disorder. In almost half of the patients, type I cryoglobulinemia is characterized by severe cutaneous involvement.

Dietary-induced ERbeta upregulation counteracts intestinal neoplasia development in intact male ApcMin/+ mice.

Most sporadic colorectal cancers (CRCs) develop through the adenoma-carcinoma sequence pathway and are initiated by adenomatous polyposis coli (APC) gene mutations. Estrogen receptor beta (ERbeta) is recognized to progressively reduce its expression in adenomatous and carcinomatous tissues in humans. Moreover, ERbeta deficiency enhances small intestinal tumorigenesis in rodents.

Estrogens, phytoestrogens and colorectal neoproliferative lesions.

Epidemiological and experimental studies suggest a protective role of estrogens against colorectal cancer. This effect seems to be mediated by their binding to estrogen receptor beta (ER-beta), one of the two estrogen receptors with high affinity for these hormones. Very recently, the demonstration of an involvement of ER-beta in the development of adenomatous polyps of the colon has also been documented, suggesting the use of selective ER-beta agonists in primary colorectal cancer prevention.
