Bilateral femur neck fractures in young adult patients are very rare in atraumatic circumstances. We report a young premenopausal female with osteomalacia secondary to vitamin D deficiency and spontaneous bilateral femur neck fractures. Patients had no reported risk factors for osteomalacia but hypovitaminosis D was noted on laboratory evaluation. Osteomalacia secondary to low serum levels of v...
In a patient receiving regular dialysis prolonged hypophosphataemia due to aluminium hydroxide therapy resulted in osteomalacia and severe proximal myopathy. Both osteomalacia and myopathy responded to correction of hypophosphataemia without vitamin D therapy.
Since phosphate is indispensable for skeletal mineralization, chronic hypophosphatemia causes rickets and osteomalacia. Fibroblast growth factor 23 (FGF23), which mainly produced by osteocytes in bone, functions as the central regulator of metabolism increasing renal excretion suppressing production 1,25-dihydroxyvitamin D. The excessive action FGF23 results hypophosphatemic diseases, include a...
the association of osteomalacia with neurofibromatosis is a very rare entity. here a 34 year old man, a known case of neurofibromatosis, is reported who presented with bone pain, hypophosphatemia, rena] phosphorus wasting, multiple looser's pseudofractures, and low bone density. treatment with high dose calcitriol and phosphate resulted in temporary treatment. permanent cure was achieved a...
Discussion. Oncogenic osteomalacia is a rare paraneoplastic syndrome of skeletal demineralization from renal phosphate loss. Patients with this disorder have the characteristic clinical, laboratory, and radiographic findings of hyperphosphaturic osteomalacia. Although the pathophysiology has not yet been clearly delineated, a humoral factor produced by the tumor is suspected to be the cause.Pur...
The aim of the study was to study the relationship between nutrition and endemic osteomalacia, resulting in bone deformation with hump back, spinal curvature and "0" legs, in persons living in high drinking water fluoride areas with skeletal fluorosis. A dietary survey was made of 30-50 families from each of three villages in high fluoride areas of China, and in 273 persons in whom skeletal flu...
Bone biopsy specimens from the iliac crest were obtained during surgical operations from 45 patients with rheumatoid arthritis (RA) and 41 with osteoarthritis (OA). Control material was obtained from 20 cases of sudden death due to cardiovascular disease. By both conventional histology and image analysis techniques about a quarter of all patients showed some osteoporosis. This was equally commo...
Background: The most common renal disease in Sjogren’s syndrome (SjS) is tubulo-interstitial nephritis, which is responsible for renal tubular acidosis type 1 (RTA-1) in around 20% of patients. Osteomalacia rarely occurs as the first manifestation of a renal tubule disorder due to a connective tissue disease such as SjS. Results and conclusion: We report a 47-year-old woman with tubular acidosi...
Plasma calcium and phosphate concentrations and alkaline phosphatase activities were examined retrospectively in 50 patients with histologically proven osteomalacia and 50 age- and sex-matched control subjects with normal bone histology. An abnormal plasma alkaline phosphatase activity was more useful than an abnormal plasma calcium or phosphate concentration in distinguishing between normal an...
