ATTENTION has been drawn to the possible adverse effects of anticonvulsant drugs on bone metabolism by a number of reports in recent years (Dent et al, 1970; Richens and Rowe, 1970; Hunter et al, 1971; Lifshitz and Maclaren, 1973; Stamp, 1974; British Medical Journal, 1976). The aim of the present study was to investigate this potentially serious side-effect of anticonvulsant therapy in the set...

Objectives: To explore the diagnostic value of 99mTc-Sestamibi multiple-phase static planar imaging and SPECT/CT in secondary hyperparathyroidism. Methods: This was a retrospective analysis of 40 cases of clinically diagnosed secondary hyperparathyroidism with multiple-phase static planar imaging, 15 min SPECT/CT fusion imaging, and ultrasonography. All cases were confirmed by pathological exam...

Figure 1: (a) X-ray of the hands showing bilateral acro-osteolysis with resorption of the distal phalangeal tufts (arrows). (b) X-ray of the skull showing abnormal bony mineralization along the patient’s calvarium. (c) X-ray of the right shoulder showing resorption of the distal end of the clavicle and also mild focal subchondral cystic change along the posterior lateral humeral head, better vi...

High doses of oral calcium or long-term calcium infusions are recommended to correct the hypocalcemia and secondary hyperparathyroidism in patients with hereditary 1,25 dihydroxyvitamin D3-resistant rickets (HVDRR). Preliminary studies revealed that calcimimetics may be a safe and effective therapeutic choice in children with secondary hyperparathyroidism. Our aim was to observe the efficacy of...

Secondary hyperparathyroidism is one of the most common and serious abnormalities in patients with chronic kidney disease. Despite recent progress in the treatment of hyperparathyroidism, advanced uraemic nodular hyperplasia, or rarely, sporadic primary adenoma accompanied by chronic renal failure is usually resistant to medical treatment and requires parathyroidectomy [1,2]. Spontaneous remiss...

Brown tumour represents a serious complication of hyperparathyroidism. Differential diagnosis, based on histological examination, is only presumptive and clinical, radiological and laboratory data are necessary for definitive diagnosis. Here we describe a case of a brown tumour localised in the maxilla due to secondary hyperparathyroidism in a young women with chronic renal failure. Hemodialysi...

High-turnover bone due to excess PTH is one of the main types of renal osteodystrophy. In addition to the classic stimuli of PTH secretion such as hypocalcemia and decreased production of active vitamin D, new mechanisms has been suggested. Furthermore, skeletal resistance to PTH, a classic stimulus of PTH secretion in uremia, has been recently revisited as an underlying abnormality.

Secondary hyperparathyroidism is a frequently encountered problem in the management of patients with chronic kidney disease (CKD). Its pathophysiology is mainly due to hyperphosphatemia and vitamin D deficiency and resistance. This condition has a high impact on the mortality and morbidity of dialysis patients. Early diagnosis of secondary hyperparathyroidism is crucial in the management of pat...

Brown tumors are focal bone lesions, encountered in patients with uncontrolled hyperparathyroidism. They can be located in any part of the skeleton. Clinically significant lesions in the craniofacial bones are rare. Craniofacial involvement may cause facial disfiguration and compromise social ease of the patient and normal functions, such as chewing, talking, and breathing. In this case report,...
