Background: Currently, online social media have become increasingly popular and can provide the opportunity to provide and acquire information regarding knowledge and attitudes toward organ donation and transplantation. To evaluate participants' knowledge about organ donation, information sources and donation principles, an on-line survey was distributed through social network in Italy., Methods: 10584 persons were invited to respond to the questionnaire, the response rate was 22.8% and a total of 2258 complete responses were analyzed., Results: The majority of participants were in favour of organ donation (94.9%), but this proportion decreased when asking for consent to donation of a family member's organs (75.2%; P<0.001). Internet represented a considerable proportion of information sources (37.2%), that were much less frequently represented by family doctors (5.6%) and school education (18.6%). Conversely, 68.5% of participants think that family doctors should provide information regarding donation and 81.9% think schools should also provide such education (P<0.001). A good knowledge about donation principles was the main factor associated with a positive attitude toward donation (P<0.001)., Conclusion: Efforts must be aimed at involving schools and family doctors in education about donation; the use of social networks can represent a way of improving such knowledge.

The demand for donor organs continues to exceed the number of organs available for transplantation. Many reasons may account for this discrepancy, such as the lack of consent, the absence of an experienced coordinator team able to solve logistical problems, the use of strict donor criteria, and suboptimal, unstandardized critical care management of potential organ donors. This has resulted in efforts to improve the medical care delivered to potential organ donors, so as to reduce organ shortages, improve organ procurement, and promote graft survival. The physiological changes that follow brain death entail a high incidence of complications jeopardizing potentially transplantable organs. Adverse events include cardiovascular changes, endocrine and metabolic disturbances, and disruption of internal homeostasis. Brain death also upregulates the release of pro-inflammatory molecules. Recent findings support the hypothesis that a preclinical lung injury characterized by an enhanced inflammatory response is present in potential donors and may predispose recipients to an adverse clinical prognosis following lung transplantation. In clinical practice, hypotension, diabetes insipidus, relative hypothermia, and natremia are more common than disseminated intravascular coagulation, cardiac arrhythmias, pulmonary oedema, acute lung injury, and metabolic acidosis. Strategies for the management of organ donors exist and consist of the normalization of donor physiology. Management has been complicated by the recent use of ''marginal'' donors and donors of advanced age or with ''extended'' criteria. Current guidelines suggest that the priority of critical care management for potential organ donors should be shifted from a ''cerebral protective'' strategy to a multimodal strategy aimed to preserve peripheral organ function.

Nutrition support in critically ill patients is not merely simple nutrition, but rather metabolic support. In the last few years, the pharmacological properties of nutrients have been specifically addressed in a new field called pharmaconutrition. This review will offer a deeper insight into this field, focusing on the properties of arginine, glutamine, antioxidants, and omega-3 fatty acids as well as the level of blood glycemia which should be maintained in critically ill patients.

Background: This study aims to assess the best postoperative analgesia during maxillofacial surgery by using small doses of ketorolac or tramadol or their association and evaluates the presence of adverse effects due to NSAID or opioid use., Methods: After their informed consent, 51 patients ASA I and II undergoing major maxillofacial surgery, were randomised in three groups and the following protocol was used: group K received ketorolac (30 mg i.v.) at the time of skin closure and repeated after 8 hrs and 16 hrs from the end of the operation. Group T received tramadol (100 mg i.v.) in the same condition; and group KT received first tramadol (100 mg i.v.) during surgery and then ketorolac (30 mg) was given in the administrations that followed. Meperidine 50 mg was used in case of unsatisfactory analgesia. Pain was evaluated using pain intensity scores 2, 4, 6, 12 and 24 hours from the end of the operation. Data was analysed using Anova and c2 test., Results: The groups were comparable with regard to age, weight, duration of surgery. Very good postoperative analgesia was recorded in three groups. There is no difference statistically between K, T and KT groups in the pain scores measured. Only a low number of patients required opioids administration to achieve adequate analgesia. The patients were considered to have achieved excellent analgesia in 64.8% in T group, in 41.2% of the K group and in 58.8% of the KT group. There were no cases of insufficient analgesia. We did not find a significant difference considering BP, HR, respiratory depression in the post-operative period. Vomiting was registered in 41.2% of this T group vs 11.2% of the K group and in 35.5% of the KT group., Conclusions: Ketorolac and Tramadol produced comparable, effective and low cost postoperative analgesia during maxillofacial surgery. There are only statistically significant differences considering side effects.

A survey of a series of caesarean section done under general anesthesia with the aid of muscle relaxation obtained by repeated doses of d-tubocurarine evidenced a tendency to worsen the Apgar index. In the light of the cases and from the literature some hypotheses are here discussed; the most reliable are based upon the fact that injections of the curare before the plasma half life of the drug end by increasing the materno foetal gradients permitting the transplacentar passage of the d-tubocurarine.
