Reality check: using stimulation modeling to plan and sell change.

As anyone who has worked with a computer knows, technology doesn't always solve problems. But when it comes to planning for health care institutions, operation simulation modeling can help executives make better decisions and create more efficient operations--by bringing more information, issues and communication power to the table.

Giant cell tumour of the temporal bone presenting as vertigo.

We report a case of giant cell tumour of the temporal bone arising in a 31-year-old man. The presenting symptoms were unusual, being rotational vertigo, unilateral tinnitus, and hearing loss. A computed tomography (CT) scan showed a large mass within the right temporal bone and the infratemporal fossa. The radiological appearance was suggestive of an aggressive primary neoplasm arising within bone. Biopsy and subsequent resection showed a giant cell tumour of bone. The tumour was histological grade 1. At two-year follow-up, there was no evidence of tumour recurrence or metastasis.

Ascertainment and natural history of treated acromegaly in Northern Ireland.

The prevalence of known cases of acromegaly in Northern Ireland in 1984 was 6.3 per 100,000 population. The incidence of newly-diagnosed cases over the preceding 25 years was 5.5 patients per year, or 0.4 patients per 100,000 population per year. This rate would be equivalent to about 200 new cases per year in the United Kingdom. Four options have been available to most of these patients--surgical hypophysectomy (transfrontal or transsphenoidal), pituitary radiotherapy (usually external cobalt beam), drug treatment with bromocriptine, or no treatment. Choice of treatment has been mainly influenced by tumour size, with the larger pituitary adenomas having surgery initially. No single form of treatment has been successful in achieving a clinical remission or cure in more than a minority of cases. The most successful outcome has been where total pituitary ablation has been achieved. Life-table analysis for the whole group shows life expectancy which is not markedly different for that of an age-matched population from Northern Ireland. Morbidity related to long term osteoarthritis and treatment complications remain a major problem. The incidence of malignant tumours is higher than would be expected.

Medical rapid prototyping and 3D CT in the manufacture of custom made cranial titanium plates.

This report describes a new method of custom making cranial titanium plates for the repair of skull defects. We have combined 3D CT imaging and surface modelling with rapid prototyping (RP) technology to produce physical models of our patients' skulls from which custom titanium plates were made. We have expanded the use of image processing tools applied to the CT image data to fabricate a representation of the skull defect. Medical RP models are relatively expensive and particular attention has been paid to developing image processing methods to reduce costs. Our technique used the patient as their own model and generated data from the contralateral side of the head where appropriate. We present the results of 10 patients who have had a custom made cranial titanium plate fitted and discuss the models for these cases. The benefits of our custom made titanium plates are reduced patient attendances to hospital and a more accurate titanium plate which has improved fitting and cosmesis.
