ReviewAdverse effects of bisphosphonates: implications for osteoporosis management.
Bisphosphonates are widely prescribed and highly effective at limiting the bone loss that occurs in many disorders characterized by increased osteoclast-mediated bone resorption, including senile osteoporosis in both men and women, glucocorticoid-associated osteoporosis, and malignancies metastatic to bone. Although they are generally well tolerated, potential adverse effects may limit bisphosphonate use in some patients. ⋯ The World Health Organization fracture risk assessment algorithm is currently available to determine absolute fracture risk in patients with low bone mass and is a useful tool for clinicians in identifying patients most likely to benefit from pharmacological intervention to limit fracture risk. This fracture risk estimate may facilitate shared decision making, especially when patients are wary of the rare but serious adverse effects that have recently been described for this class of drugs.

Comparative StudyLeft ventricular systolic and diastolic function in patients with apical ballooning syndrome compared with patients with acute anterior ST-segment elevation myocardial infarction: a functional paradox.
To compare left ventricular (LV) systolic and diastolic function in patients with apical ballooning syndrome (ABS) and those with acute myocardial infarction (AMI) using 2-dimensional Doppler echocardiography and strain rate imaging (SRI). ⋯ Compared with patients with AMI, those with ABS showed the functional paradox of worse initial LV systolic function with larger LV size but better LV diastolic function. The early systolic strain rate and postsystolic shortening were greater in patients with ABS than in those with AMI; hence, these measurements can be helpful in distinguishing ABS from AMI and in detecting myocardial viability.
