Total thyroidectomy (TT) is the standard of care for differentiated thyroid cancer (DTC), but still there is no consensus about the role of routine use of prophylactic central lymph node dissection. The aim of this study was to analyze our results of TT without prophylactic central lymphadenectomy in the treatment of DTC. Clinical records, between January 1998 and December 2005, of 221 patients undergoing TT, without prophylactic central lymph node dissection, were retrospectively evaluated. Two hundred and eleven patients (95.47 %) also underwent radioiodine (RAI) ablation followed by thyroid stimulating hormone (TSH) suppression therapy. In patients with loco-regional lymph nodal recurrence, lateral and central lymph node dissection was performed. The incidence of permanent hypoparathyroidism (iPTH <10 pg/ml) and permanent vocal fold paralysis were, respectively, 0.91 and 0.91 %. After a 9.6 ± 3.5 years mean follow-up, the rate of loco-regional recurrence, with positive cervical lymph nodes, was 3.16 % (7/221 patients). In these cases a lateral and central lymphadenectomy was carried out without significant complications. Our results showed that TT without prophylactic central lymph node dissection, followed by RAI ablation, was associated with low morbidity and low loco-regional recurrence rate, even if the lack of a control group treated with TT plus prophylactic central lymphadenectomy suggests caution against generalization of our assumption. Such last combined procedure could be indicated in high-risk patients, in whom loco-regional recurrence is more frequent. However, given the trend in the literature toward prophylactic lymphadenectomy and the avoidance of RAI treatment, prospective randomized trials should be conducted to better clarify this issue.

Exercise training started early after STEMI reduces stress-induced hypoperfusion and improves LV function and contractility. Exercise-induced changes in myocardial perfusion and function were associated with the absence of unfavourable LV remodelling and with an improvement of cardiovascular functional capacity.

Hyperemic MBF and CFR provide incremental information about the presence of CAD over CAC score and perfusion imaging parameters. The combined use of CAC, myocardial perfusion imaging and quantitative coronary vascular function in may help predict more accurately the presence of obstructive CAD.

In patients with suspected CAD, CFR provides significant incremental risk stratification over established cardiac risk factors and CAC score for prediction of adverse cardiac events.
