Patients rely on their primary care physician to manage multiple, often chronic medical conditions that require prescription medications. Balancing the risk to benefit of treatments can be challenging and requires that the primary care physician stay abreast of new information regarding risks and benefits. The number of medications with reported adverse effects on skeletal health is expanding. This review focuses on medications recently added to the list of "bad to the bone" drugs and on recent advances in management of glucocorticoid-induced osteoporosis. A practical approach to assessing and managing the skeletal risks is outlined. [ABSTRACT FROM AUTHOR]

Acquired osteosclerosis is a rare disorder of bone formation but an important consideration in adults with sclerotic bones or elevated bone density results. In such patients, malignancy, hepatitis C, and fluorosis should all be considered when making a diagnosis. We describe 4 patients evaluated at our Metabolic Bone Disease Clinic from May 1, 1997, to July 1, 2006, whose bone disorders resulted from chronic fluoride exposure due to excessive tea intake. Three of these patients had toxic serum fluoride levels (> 15 micromol/L). Although the clinical presentation of the patients varied, all 4 had an unexpectedly elevated spine bone mineral density that was proportionately higher than the bone mineral density at the hip. Other clinical features included gastrointestinal symptoms such as nausea, vomiting, and weight loss; lower extremity pain sometimes associated with stress fractures of the lower extremities; renal insufficiency; and elevated alkaline phosphatase levels. Readily available, tea often contains high levels of fluoride. Obsessive-compulsive drinking behaviors and renal insufficiency may predispose to excessive fluoride consumption and accumulation. The current cases show that fluoride-related bone disease is an important clinical consideration in patients with dense bones or gastrointestinal symptoms and a history of excessive tea consumption. Furthermore, fluoride excess should be considered in all patients with a history of excessive tea consumption, especially due to its insidious nature and nonspecific clinical presentation.

Megestrol acetate is a progestational agent for treatment of metastatic breast cancer and endometrial cancer. Megestrol has also been used as an appetite stimulant for patients with human immunodeficiency virus and malignancy who experience cachexia and wasting; also, megestrol can be beneficial in relieving hot flashes in women and men. Megestrol has been shown to have a glucocorticoidlike effect and has been associated with substantial suppression of plasma estradiol levels. We describe 2 patients who recently presented to our Metabolic Bone Disease Clinic with severe osteoporosis complicated by multiple vertebral fractures experienced while the patients were receiving high-dose megestrol therapy. The patients had evidence of adrenal axis suppression but recovered fully after megestrol was discontinued. We speculate that megestrol was an important factor in the development of osteoporosis and subsequent fractures. Further study is warranted to clarify the relationship between megestrol and its potential for adversely affecting the skeleton. [ABSTRACT FROM AUTHOR]
