Cardiac SABR: Image matching techniques for accurate treatment delivery.

Background: Ventricular tachycardia is an irregular heartbeat conventionally treated using invasive cardiac catheter ablation and medication. However, when standard treatments have been exhausted, cardiac SABR provides a final treatment option to this high-mortality condition. Complex diagnostic mapping and planning scans enable multi-disciplinary target delineation for a 25Gy single fraction.

Thyroid function after subtotal thyroidectomy for hyperthyroidism.

Among 76 patients who had had a subtotal thyroidectomy for hyperthyroidism from one to seven years previously recurrent hyperthyroidism was found in three and hypothyroidism in 13. The remaining 60 subjects were clinically euthyroid but a raised level of serum thyroid-stimulating hormone (TSH; greater than 5-0 mu U/ml) was found in 39. Analysis of the data showed that their serum thyroxine was significantly lower than in the subjects with a normal TSH.
