Computerized gray-scale sonography provides an objective measure of thyroid hypoechogenicity, which correlates well to the clinical stages of HT. Use of this modality may prove beneficial in the diagnosis and follow-up of patients with HT.

CFDS is a useful tool in the differential diagnosis of AIT. This differentiation appeared to be of clinical relevance as regards therapeutic choice. Separate evaluation of parenchymal blood flow from that of nodules may prove beneficial in the diagnosis of underlying thyroid diseases in patients with type 1 AIT.

We report a case of localized Castleman's disease of mesentery, studied with sonography, that was incidentally detected as an abdominal mass in a patient with Graves' disease. Its lymphatic nature and mesenteric origin was indicated preoperatively on the basis of gray-scale and color Doppler sonographic features.

Dabigatran is an oral, direct thrombin inhibitor approved by international regulatory agencies for stroke prevention in patients with paroxysmal or persistent non-rheumatic atrial fibrillation (AF). The benefits of dabigatran are widely described, but its use in the geriatric population is not without risk. Chronic kidney disease is a common comorbidity with AF, and thus frequent checks of renal function in elderly patients are recommended. We report a case of dabigatran intoxication in an elderly man affected by heart failure and worsening renal function, who developed acute hepatitis and coma, which was successfully treated with continuous veno-venous hemodiafiltration. Although extracorporeal therapy has been suggested as a strategy for clearing dabigatran during acute bleeding, this approach may be useful in other dabigatran-related, life-threatening conditions, such as that described in this report.
