PURPOSE Despite recent improvements in therapeutic management of osteosarcoma, ongoing challenges in improving the response to chemotherapy warrants the development of new strategies to improve overall patient survival. Among them, HSP90 is a molecular chaperone involved in the maturation and stability of various oncogenic proteins leading to tumor cells survival and disease progression. We ass...

while traditionally associated with radiation therapy for head and neck cancer, osteonecrosis of the jaw has recently been described mainly in breast cancer and multiple myeloma patients undergoing long-term intravenous bisphosphonate treatment [1, 2, 3, 4, 5, 6, 7, 8, 9, 10,11, 12, 13, 14, 15]. Bisphosphonates are used to treat bone metastases, as they decrease bone resorption, primarily throu...

A convenient and practical synthesis of imidazol-1-yl-acetic acid hydrochloride was achieved via N-alkylation of imidazole using tert-butyl chloroacetate followed by a non-aqueous ester cleavage of the resulting imidazol-1-yl-acetic acid tert-butyl ester in the presence of titanium tetrachloride. The synthesized imidazol-1-yl-acetic acid hydrochloride was then utilized to prepare zoledronic acid.

OBJECTIVES Osteoporosis has become an increasing concern for older people as it may potentially lead to osteoporotic fractures. This study is designed to assess the efficacy and safety of ten therapies for post-menopausal women using network meta-analysis. METHODS We conducted a systematic search in several databases, including PubMed and Embase. A random-effects model was employed and result...

PURPOSE Malignant pleural mesothelioma (MPM) is a rare malignancy with a dismal median survival of <12 months with current therapy. Single and combination chemotherapy regimens have shown only modest clinical benefit. In preclinical studies, nitrogen-containing bisphosphonates (zoledronic acid) inhibit growth of mesothelioma cells by different mechanisms: inhibition of mevalonate pathway, inhib...

BACKGROUND Zoledronic acid-induced uveitis (ZAIU) is rare but severe, and has been recently considered part of an acute phase reaction. Only 15 cases have been reported since 2005. Here we describe a case with macular edema, which is the first reported case observed after long-term alendronate tolerance. CASE PRESENTATION A 63-year-old Asian woman received her first intravenous zoledronic aci...

INTRODUCTION Osteoporosis is an under-recognized problem threatening men. Bisphosphonates are the main treatment but their comparative efficacy is unclear for men with osteoporosis. Therefore, we performed this systematic review with network meta-analyses to summarize the evidence of comparative efficacy of bisphosphonates in men with osteoporosis. METHODS We completed network meta-analyses w...

The osteoporosis is a major health threat that affects every third post-menopausal women. Postmenopausal osteoporosis is complicated with vertebral, femoral or radius fracture. This prospective study on post-menopausal osteoporosis was carried out in the Pain Centre, Department of Anaesthesia, Analgesia and Intensive Care Medicine of BSMMU, Dhaka during the period of January 2008 to January 201...
