The research investigated the effects of acute ACTH 1-17 administration on plasma cortisol, short-term memory, anxiety state, blood pressure and heart rate. In a double blind crossover design, healthy volunteers were serially evaluated at 5 min, 20 min, 40 min, 60 min after injection of ACTH 1-17 or placebo in separate sessions. Results show that ACTH 1-17 produced, in addition to an increase in plasma cortisol (5 min - 60 min), significant improvements in short-term memory (5 min), a reduction in anxiety (20 min and 40 min), and an increase in systolic (5 min and 20 min) and diastolic blood pressure (5 min). If confirmed by other studies, the short-term memory effect of ACTH 1-17 at 5 min after i.v. could suggest a central action of the peptide, and confirm the role of HPA axis as a modulator of performance and emotional arousal during acute environmental changes.

Surgical treatment of multinodular goiter: incidence of lesions of the recurrent nerves after total thyroidectomy.

The problems concerning surgical goiter treatment are discussed, particularly the morbidity of total thyroidectomy and possible injury to recurrent nerves in comparison to the partial resection of the gland. We discuss our case material and review the literature. We conclude that total thyroidectomy seems to be the most effective surgical procedure with lower morbidity than subtotal thyroidectomy.

[Experience at an ambulatory surgical service for thyroid diseases].

Based of a personal series of 206 patients, the authors evaluate their personal experience of an outpatient surgery ward for thyroid pathologies. The paper reports the diagnostic and therapeutic approaches both in patients undergoing surgery and those who do not. Attention is focused on the importance of the multidisciplinary team and the quality of the results of a homogeneous follow-up.
