Policy recommendations for addressing privacy challenges associated with cell-based research and interventions.

Background: The increased use of human biological material for cell-based research and clinical interventions poses risks to the privacy of patients and donors, including the possibility of re-identification of individuals from anonymized cell lines and associated genetic data. These risks will increase as technologies and databases used for re-identification become affordable and more sophisticated. Policies that require ongoing linkage of cell lines to donors' clinical information for research and regulatory purposes, and existing practices that limit research participants' ability to control what is done with their genetic data, amplify the privacy concerns.

[Emergency treatment of bleeding esophageal varices].

Background: The hemorrhage from breakup of the varix esophageal is a dramatic complication of the hypertension of the circle portal, numerous attempts have stayed performed for identify the patients that present taller risk of hemorrhage, to the purpose of to establish the preventive more proper measures to arrive before the first episode of hemorrhage. The treatment of the patient with high pressure portal stays still today extremely controversial, to concern the choice of the more opportune strategies, that for it as concerns the choice of the better moment for effect the single therapies.

Methods: We have taken 63 patients treatises in urgency for esophageal variceal bleeding in consideration, we of the initial group of the 63 patients have subjected endoscopic 34 patients, subjected elastic binding of the varix 20 patients, and to derivative interventions in urgency 9 patients.

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.

Neuroendocrine tumors of the gastroenteric canal. Anatomopathological and diagnostic-therapeutic definition. Description of a case with a rare cecal localisation.

The authors take the case of a neuroendocrine tumour of the cecum as the starting point for an analysis of the anatomopathological and diagnostic-therapeutic aspects of these neoplasms. Furthermore, the authors underline that neuroendocrine tumours (NET) of the colon represent an extremely rare nosological entity and that they are heterogeneous from a clinical and biochemical point of view, thus making a reliable preoperative diagnosis a problem that is still difficult to resolve today.

Pericardial cysts of the mediastinum.

Pericardial cysts are an uncommon benign disease. Their treatment, in the past, was based on excision by thoracotomy or, in selected cases, on percutaneous aspiration. The progress of video-assisted thoracoscopy gave new possibilities, but most surgeons still consider the thoracotomic approach as the treatment of choice.
