    Total thyroidectomy can be challenging in high-risk patients. Local cervical anesthesia with sedation is an alternative to general anesthesia. A 33-year old male patient with cyanotic congenital heart disease due to unrepaired tricuspid atresia type Ic and associated pulmonary arterial hypertension presented with tachycardic atrial fibrillation and amiodarone-induced thyrotoxicosis resulting in recurrent hemodynamic instability. Because of difficulties controlling the thyrotoxic state, the indication for total thyroidectomy was established. Total thyroidectomy was subsequently performed using local anesthesia combined using a hypnosis-analgesia technique instead of intravenous sedation. The intervention and the post-operative course were uneventful. A well-established therapist-patient relationship is crucial for a successful induction of hypnosis. Patient motivation and expectations are equally important for a successful implementation of this approach. We conclude that hypnosis combined with local anesthesia provides an effective alternative in selected patients with very high anesthesiological risk

    The report of the COST ACTION 621 “Groundwater management in coastal karstic aquifers” is the result of the comparison and fusion of personal experiences of researchers coming from 15 european countries, which faced in their job many aspects both of the functioning and the managing of these karstic coastal aquifers. At the end of five years of meetings and visits held in towns and places of the 15 countries taking part to this COST ACTION 625, it has been written this report in the aim of fixing the work made and the experience carried on. On the other hand this report contains a very interesting and updated compilation of engineering methodologies adopted for groundwater exploitation in coastal karstic aquifer, and it presents many examples of catchment works, realized in european countries, of these methodologies. In particular this chapter 4 deals with different type of catchment works engineering. As a matter of fact in karst aquifers due to the general lack of surface water, groundwater exploitation is the only way to satisfy water demand, which is increasing in every coastal area, and usually surpasses the dynamic potential replenishment of the natural freshwater system. This fact causes a phenomenon named overexploitation, which is the origin of seawater intrusion. The engineering of catchment works in karstic coastal aquifers deals mainly about the problem of groundwater exploitation without starting seaweater intrusion and the consequent groundwater contamination
