A middle aged man presented with a 4 year history of painful swelling of both knees and pustular acne on his back. The MRI scan of the knees showed gross synovitis, so did the histopathology of the synovium. A diagnosis of SAPHO syndrome was made and he was treated with IV pamidronate. His pain reduced and acne completely cleared up on therapy. A dermatologist has rarely made a diagnosis of SAP...

Hypercalcemia of malignancy (HCM), a PTH-independent process, usually occurs in solid tumors, multiple myeloma, and occasionally lymphomas. It generally results from excess secretion parathyroid hormone related protein (PTHrP) by the tumor, osteolytic metastases, or rarely, tumor production 1,25-(OH)2 vitamin D. We present an unusual case HCM patient with refractory acute myelogenous leukemia (...

A 10-year-old boy was referred to us for evaluation of FUO accompanied with bone pain in both calves. Three hours after intravenous injection of 13 mCi of 99mTc-MDP, whole body scan in multiple spot views was performed. The scan showed symmetrical areas of diffusely increased tracer uptake in multiple long bones. Histopathologic evaluation confirmed osteosclrosis and fibrotic changes...

The response to the bisphosphonate, pamidronate, is reported in a child with osteogenesis imperfecta who had recurrent symptomatic hypercalcaemia after immobilisation following fractures. Oral clodronate was effective in the prevention of immobilisation hypercalcaemia in the same child. The bisphosphonates may have other roles in osteogenesis imperfecta by decreasing bone turnover.

Background Osteogenesis imperfecta (OI) is a genetic disorder with increased bone fragility and low bone mass, the incidence has been estimated at 1 in per 10000-20000 births, however milder forms of OI are probably under recognized. Cyclical intravenous therapy with the biphosphonate pamidronate has been reported to be beneficial in children and adolescents with moderate to severe forms of OI.

Hypercalcemia can causes life threatening complications. We report an infant with severe hypercalcemia due to congenital mesoblastic nephroma. Hypercalcemia was corrected before nephrectomy by pamidronate. According to our knowledge this is a rare case with severe neoplasm induced hypercalcemia among neonates who treated by bisphosphonates. The aim of this report is to define new approach to ne...

The in vivo activities of three bisphosphonates were determined against Leishmania donovani and Toxoplasma gondii. Alendronate was essentially inactive against both parasites. Pamidronate was active against L. donovani by intravenous administration. Risedronate had a 50% effective dosage of five 2.6-mg/kg of body weight intraperitoneal doses against L. donovani-infected mice but was less effect...
