Extractions: Hyparathyroidism 4-531 To see Images first. This process is associated with the production of hormone from the parathyroid glands which increases bone turnover. The metaphyses of bones are particularly effected and any area where there is a greater bone turnover than other sites can show increased bone resorption. The isotope scan below indicates the usually affected parts. Put simply, the effect of the hormone is to maintain or elevate the serum free calcium. The presence of Vitamin D. is necessary for the hormone to have its full effect upon the bone and thus the patterns of primary and secondary hyperparathyroidism will be different. In the primary condition there is absorption of the tufts of the terminal phalanges in the hands and feet and subperiosteal bone resorption with particular effect at the level of the bone metaphysis. Cysts can form anywhere is primary hyperparathyroidism and these comprise well defined lytic lesions within the bone which resemble simple bone cysts. Under the microscope they contain a mixture of spindle cells and fibroblasts. If the primary hyperparathyroidism is treated these bone cysts will often resolve, leaving an area of sclerosis. The 'brown tumour' is characterised by the haemorrhage into the cyst in which case the cysts can often be permanent as a lytic area. Close examination of the hand radiographs is the most helpful in hyperparathyroidism and in which case the phalanges are seen to be asymmetrical with subcortical bone resorption on their radial side. A minute examination of the tufts will usually reveal that the continuous line of cortical bone which delinates the tuft is interrupted and the appearance resembles a lace border.

Holohan, M.D., FACP. Status: Technology Assessment: Published, 1996. Language: English Primary Objective: To assess which techniques, if any, are clinically useful in the medical management of patients with bone loss due to asymptomatic primary hyperparathyroidism. Methods Used: Review of published literature, collection of information from interested public in response to a Federal Register notice of intent to undertake assessment, solicitation of data from other agencies of the U.S. Public Health Service (PHS). Data Identification: Published literature identified by search of the MEDLINE database, references from bibliographies of reviewed articles, data submitted by other Federal agencies. Study Selection: All published material of primary data addressing bone loss in patients with PHPT, fracture risk in patients with PHPT and changes in BMD following surgery for PHPT.

Extractions: Click On Images for Enlarged View Clinical History: Hand and low back pain in a patient on dialysis. Findings: A radiograph of both hands and an AP radiograph of the spine were obtained. The radiograph of the hand demonstrates osteopenia. Multiple lytic and somewhat expansile lesions with well-defined borders, that are in part sclerotic, are present bilaterally. These lesions are present in the distal aspects of the metacarpals and in the proximal, mid and distal phalanges. Subperiosteal resorption is present along the radial aspect of the proximal and mid phalanges bilaterally involving the first through fifth fingers. Generalized thinning of the cortices is present of all the metacarpals suggestive of endosteal bone resorption. The radiograph of the spine demonstrates extensive erosions of both SI joints, which are widened bilaterally and symmetrically. Diagnosis: Secondary hyperparathyroidism related to renal osteodystrophy.

Author details Abstract Objective: To examine changes in presentation of primary hyperparathyroidism and rates of parathyroidectomy in Northern Sydney (the Northern Sydney Area Heath Service) and New South Wales (NSW). Design: Setting: University of Sydney Endocrine Surgical Unit, Royal North Shore Hospital. Participants: 1613 patients undergoing parathyroidectomy during the study period. Main outcome measures: Age-standardised parathyroidectomy rates and indications for surgical intervention. Results: The age-standardised rates of parathyroidectomy for primary hyperparathyroidism in women have increased significantly in Northern Sydney from 0.14 cases per 100 000 in 1976 to 7.7 cases per 100 000 in 1996 ( P P P Conclusions: The rate of parathyroidectomy procedures has increased markedly in Northern Sydney and in NSW. The investigation of osteoporosis has led to the diagnosis of primary hyperparathyroidism in an increasing proportion of cases and has contributed to the growing surgical referral rates.
