RESUMEN
The follow-up of Differentiated Thyroid Cancer conventionally includes serum thyroglobulin and periodic Whole Body Scans. The uptake of 131-I in normal and pathological tissues different from metastatic thyroid cancer sites is a cause of false-positive scans. Among them, mediastinal uptake caused by thymic hyperplasia can be observed. The aim of the present study was to review a series of 573 patients with differentiated thyroid cancer treated with 131-I after surgery between 1992 and 2003 looking above all for those with mediastinal images resembling thymus. This evaluation is presented together with some hypotheses on the relationships between thymus and thyroid. Moreover, some considerations are made on the differential diagnosis between thymus and mediastinal tumour thyroid residues.

The Authors have analyzed the effect of Cefotetan in 20 patients affected by bronchopulmonary pathologies supported by anaerobic bacterium. During 7 days doses of 50 mg. pro Kg/pro die were given. From beginning to end of the treatment clinical, hematochemical and radiological data were evaluated. Bacteriological analysis was made on samples drawn with BFS according to a traditional method and with microbiology specimen brush. Almost all the patients (95%) realized improvements in clinical symptomatology and in radiological picture.
