We present 3 cases of patients with castration-resistant prostate cancer and bone metastases treated with Ra, belonging to our prospective and multicenter ChoPET-Rad study. All patients underwent clinical, hematological, and biochemical monitoring between each Ra administration. Initial and follow-up F-fluorocholine PET/CT and Tc-biphosphonate bone scintigraphy were performed previously and after the third Ra administration. Both techniques correctly established the response to treatment, in agreement to the biochemical response, although differences in the disease expression (concordant and discordant patterns) were found because of the different radiotracer biodistribution and molecular information derived from them...

Synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome is a rare disease which is often misdiagnosed and under-recognized, because of its peculiar and heterogeneous clinical presentation. Its main features consist of cutaneous and osteoarticular manifestations, the latter affecting more often the anterior chest wall and having typical radiologic findings. There are no validated diagnostic criteria for SAPHO and no guidelines for treatment, due mainly to its rarity; as a consequence, therapy is empirical and aimed to control pain and modifying inflammatory process...

BACKGROUND: Although bone grafts are commonly used in reconstructive surgeries, they are sensitive to local perfusion and are thus prone to severe resorption. Biphosphonates can inactivate osteoclasts and can be used to control the undesirable bone resorption. OBJECTIVE: To assess the effect of administration of biphosphonates on bone resorption. METHODS: 20 patients with bony defects who were candidates for free autogenous grafts were randomized into "pamidronate" and "control" groups...

Titanium implants are widely used on an increasing number of patients in orthopedic and dental medicine. Despite the good survival rates of these implants, failures that lead to important socio-economic consequences still exist. Recently, research aimed at improving implant fixation, a process called osseointegration, has focused on a new, innovative field: systemic delivery of drugs. Following implant fixation, patients receive systemic drugs that could either impair or enhance osseointegration; these drugs include anabolic and anti-catabolic bone-acting agents in addition to new treatments...

We tested a series of sulfur-containing linear bisphosphonates against Toxoplasma gondii, the etiologic agent of toxoplasmosis. The most potent compound (compound 22; 1-[(n-decylsulfonyl)ethyl]-1,1-bisphosphonic acid) is a sulfone-containing compound, which had a 50% effective concentration (EC50) of 0.11 ± 0.02 μM against intracellular tachyzoites. The compound showed low toxicity when tested in tissue culture with a selectivity index of >2,000. Compound 22 also showed high activity in vivo in a toxoplasmosis mouse model...

Paget's disease of bone is a localised chronic osteopathy which produces bone deformities, bone hypervascularity, structural weakness and altered joint biomechanics. Although radiological diagnosis of Paget's disease of bone is usually straightforward, monostotic cases may potentially raise specific problems which require invasive and expensive procedures such as bone biopsies. The pelvis and upper femur are frequently affected, resulting in disabling hip disease that may require total hip arthroplasty. We report a case of Paget disease of bone in an 84-year-old woman, which was initially identified as avascular necrosis of the hip, reason for which she underwent total hip arthroplasty...

Zoledronic acid (ZA) is a biphosphonate used for osteoporosis treatment and also proved to be effective to reduce the pain induced by bone metastases when used as adjuvant therapy in solid cancers. However, it has been recently proposed that ZA could have direct anti-tumour effects, although the molecular mechanism is unknown. We herein unravel a novel anti-tumour activity of ZA in prostate cancer (PCa), by targeting the pro-tumorigenic properties of both stromal and immune cells. Particularly, we demonstrate that ZA impairs PCa-induced M2-macrophages polarization, reducing their pro-invasive effect on tumour cells and their pro-angiogenic features...

Osteoporotic vertebral fractures are uncommon in young adults and usually indicate an underlying disease. Systemic mastocytosis is a myeloproliferative neoplasm, which can be associated with osteoporosis. A previously healthy 30-year-old man presented with an L4 burst fracture after lifting a heavy object. He was operated with laminectomy and posterior lumbar instrumentation. During surgery, abnormally soft bone was noted. Postoperatively, osteoporosis was confirmed with measurement of bone mineral density...

BACKGROUND: Bone lytic lesion in Multiple myeloma are the most commonly presented symptoms which require treatment with bisphosphonates (BPs). BPs are providing supportive care, reducing the rate of skeletal morbidity but evidently not abolishing it, the criteria for stopping their administration have to be different from those used for classic antineoplastic drugs, and they should not be stopped when metastatic bone disease is progressing. Osteonecrosis of the jaw (ONJ) has been associated recently with the use of BPs...

Osteonecrosis of the jaw (ONJ) is one of the most relevant and specific complication of biphosphonates. ONJ in patients receiving zoledronic acid every 3 to 4 weeks is frequently described, but the ONJ biyearly regimen used to reduce aromatase inhibitor associated bone loss (AIBL), is rarely reported. A literature review, focusing on the important trials using zoledronic acid to reduce AIBL, found that the mean risk of developing ONJ when zoledronic acid is used biyearly varies between 0.12% and 0.7%.

Bisphosphonates are widely used both in the multidisciplinary management of bone metastases, especially osteolytic lesions from solid tumors or multiple myeloma, and of osteoporosis.Aseptic osteonecrosis, especially of the jaw, is among the well-known, although uncommon, side effects of bisphosphonates. Osteonecrosis of other bones has been very rarely reported with the use of bisphosphonates.We describe a rare case of osteonecrosis of the distal femur associated with the use of bisphosphonates in a 74 years old female patient with metastatic breast cancer...

Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is a severe bone disease for which the pathogenetic mechanisms and risk factors are not fully understood. The present study evaluated the data of 652 patients with bone metastasis that had undergone treatment with biphosphonates. Subsequently, 24 patients with BRONJ and 20 control patients without BRONJ that were treated with zoledronic acid were enrolled. It was found that BRONJ occurred in 3.6% of patients. The mean age and the administration of dental treatment were found to be significantly associated with BRONJ development (P=0...

Calcific uremic arteriolopathy or alciphylaxis is a malignant form of calcification of small arteries and arterioles, usually present in patients with chronic kidney disease and dialysis therapy. It causes high mortality. Histological distinctive feature are calcium deposits lining vascular intima. Calcification of medial muscle layer, inflammation and necrosis of subcutaneous adipose tissue are frequent. The disease begins with painful violaceous mottling, resembling livedo reticularis. Ths skin lesion progresses to ulcers and eschars, sometimes it becomes very vulnerable to secondary infection which can often develop into fatal sepsis...
