Long term treatment with intravenous pamidronate in two children with severe form of juvenile Paget's disease

Verfurth Katja , Hovel Matthias , Schundeln Michael , Bauer Jens , Grasemann Corinna

Presenting problem: Severe forms of juvenile Paget’s Syndrome (JPD) result in extreme bone turnover, necessitating long-term treatment with anti-resorptive drugs to control for bone pain and modeling of bones.Objective: To report clinical and biochemical effects of intravenous treatment with Pamidronate in two children with severe forms of JPD over a time period of 3 and 9 years, respectively. Treatment was commenced at 12 months and 3 years of age,...

New perspectives in diagnosis and management of optic neuropathy in fibrous dysplasia: utility of optical coherence tomography and computed tomography measurements

Pan Kristen , FitzGibbon Edmond , Lee Janice , Collins Michael , Boyce Alison

Objectives: Optic neuropathy (ON) is a critical complication of fibrous dysplasia (FD). Early surgical decompression can prevent blindness; however, prophylactic intervention may cause blindness from intra-operative nerve damage. There is therefore a critical need to develop diagnostic tests for accurate and early detection of ON in patients with FD. Currently used methodologies, including radiographic evaluation of optic canal size and optic nerve length, are suboptimal and c...

Microstructural adaptation of bone tissue of the facial skeleton to the distribution of occlusal load under physiological conditions

Janovic Aleksa , Milovanovic Petar , Saveljic Igor , Nikolic Dalibor , Hahn Michael , Busse Bjoern , Rakocevic Zoran , Filipovic Nenad , Amling Michael , Djuric Marija

Despite widely accepted classical mechanical theory of buttresses as a load bearing areas in the midfacial skeleton, the data related to its microstructural adaptation on functional demands are scarce. In this study we investigated microstructural features of the different regions in the facial bones in relation to the occlusal load dissipation using a combination of finite element analysis (FEA) and micro-CT analysis (μCT). The FEA was performed on the model of the dry h...

Micro-morphological properties of osteons reveal changes in cortical bone stability during aging, osteoporosis and bisphosphonate treatment in women

Bernhard Andreas , Milovanovic Petar , Hahn Michael , Djonic Danijela , Krause Matthias , Breer Stefan , Pueschel Klaus , Zimmermann Elizabeth A , Djuric Marija , Amling Michael , Busse Bjoern

Bone remodeling is the key process in bone structural reorganization, and its alterations lead to changes in bone mechanical strength. Since osteons reflect different bone remodeling patterns, we hypothesize that the femoral cortex of females with miscellaneous age, disease, and treatment conditions will display distinct osteonal morphology and osteocyte lacunar numbers along with different mechanical properties.The specimens used in this study were coll...

Estimation of vertebral and femoral strength during the first three years of denosumab therapy using an alternative smooth non-linear finite element methodology

Zysset Philippe , Pahr Dieter , Engelke Klaus , Genant Harry , McClung Michael , Kendler David , Recknor Christopher , Kinzl Michael , Schwiedrzik Jakob , Museyko Oleg , Wang Andrea , Libanati Cesar

Denosumab subcutaneous administration every 6 months reduced the incidence of new fractures in postmenopausal women with osteoporosis by 68% at the spine and 40% at the hip over 36 months compared with placebo in the FREEDOM study (Cummings et al., NEJM, 2009:361:756). This efficacy was supported by differential improvements from baseline in vertebral and femoral strength at 36 months (18.2 and 8.6%, respectively) estimated by an established voxel-based finit...

Autoimmune hyperphosphatemic tumoral calcinosis

Ramnitz Mary Scott , Burbelo Peter , Egli-Spichtig Daniela , Perwad Farzana , Romero Christopher , Ichikawa Shoji , Farrow Emily , Econs Michael , Guthrie Lori , Gafni Rachel I. , Collins Michael T.

Background: Hyperphosphatemic familial tumoral calcinosis (HFTC)/hyperostosis-hyperphosphatemia syndrome (HHS) is an autosomal recessive disorder due to deficiency of or resistance to intact fibroblast growth factor 23 (FGF23). This leads to hyperphosphatemia, increased renal reabsorption of phosphorus (TRP), and elevated or inappropriately normal 1,25-dihydroxyvitamin D (1,25D). Affected individuals may develop ectopic calcifications and/or diaphyseal hyperostosis. Mutations ...

Occurrence of vitamin D and vitamin K deficiency in children with low-energy fractures

Karpinski Michal , Chojnowska Sylwia , Maresz Katarzyna , Milewski Robert , Popko Janusz , Badmaev Vladimir

Objective: Bone fractures are very common in children and their number is growing every year. Vitamin D has a proven role in the prevention of fractures. In the recent study, we have shown that children with low-energy fractures have significantly lower vitamin D blood levels compared to the children without fractures. Our data indicate that higher levels of vitamin D reduced the risk of fracture by 1.06 times (P<0.0005).Past decade has seen...

Low-magnitude high-frequency vibration improves fracture healing in aged, ovariectomized mice

Wehrle Esther , Bindl Ronny , Wehner Tim , Heilmann Aline , Fischer Lena , Noland Jarrod , Amling Michael , Ignatius Anita

Introduction: Fracture healing is impaired in aged and osteoporotic patients. Because bone formation is tightly regulated by the mechanical conditions in the fracture gap and because suitable mechanical stimuli improve fracture healing (Claes et al. 1998), we investigated whether low-magnitude high-frequency vibration (LMHFV; Rubin et al. 2004) is able to improve delayed fracture healing induced by age and ovariectomy in mice.Sudy desig...
