ReviewPreoperative evaluation in geriatric surgery: comorbidity, functional status and pharmacological history.
The demand for elective and emergency surgery by older patients is increasing. This review examines the current practice of preoperative evaluation in geriatric anesthesia and provides an overview of new insights in this field. Preoperative anesthesia consultation is essential to examine the patient, evaluate the operative risk and plan preventive perioperative actions. ⋯ A strong joint action with the surgical team is essential. Currently, while many resources are employed to assess preoperative cardiac risk and despite the dramatic increase in the number of elderly surgical patients, the association between older age itself and surgical complications has not been fully investigated, and preoperative evaluation of functional status is not yet a part of routine preoperative practice. Creating a new culture and developing appropriate clinical, scientific and relational approaches to these patients represent the core of the challenge.

ReviewVentilator-induced lung injury and sepsis: two sides of the same coin?
Unequivocal evidence from both experimental and clinical research has shown that mechanical ventilation can damage the lungs and initiate an inflammatory response, possibly contributing to extrapulmonary organ dysfunction. This type of injury, referred to as ventilator-induced lung injury (VILI), resembles the syndromes of acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS). VILI can trigger a complex array of inflammatory mediators, resulting in a local and systemic inflammatory response. ⋯ On the other hand, current scientific evidence supports a link between VILI and the development of extrapulmonary organ dysfunction, similar to how most severe cases of sepsis are clinically manifested. In addition, functional genomics approaches using a gene array methodology to measure lung gene expression have identified differential patterns of gene expression in animal models of VILI, similar to those gene pathways activated during experimental and clinical sepsis. In this line of thought, we hypothesize that injurious mechanical ventilation could be responsible for the perpetuation and worsening of sepsis in some patients and for the development of a sepsis-like syndrome in others.

In 2007 the non-heart-beating organ donation (NHBD) "Programma Alba" (Sunrise Programme) started in Pavia, Italy. The initial plan was to cut down waiting list for kidney transplantation, while its final aim is to shorten organ transplantation waiting lists. When compared to European countries and the USA, the Italian NHBD program has taken longer to get established. ⋯ Of these, six NHBD kidneys have been transplanted. Currently, four patients are out of dialysis. This report is a detailed description of NHBD "Programma Alba" and its preliminary results.

ReviewPharmacogenetic treatment of acute respiratory distress syndrome.
Acute lung injury (ALI) and the acute respiratory distress syndrome (ARDS) occur due to systemic inflammatory disorders or direct injury to the lung. The occurrence of ALI/ARDS is sporadic and is not reliably predicted by the type or severity of injury. ⋯ Despite these advances, pharmacologic therapies have yet to be developed for the prevention or treatment of disease. We anticipate that continued improvement of our understanding of the genetic and pathophysiologic mechanisms underlying ALI/ARDS combined with future clinical trials will allow pharmacogenetic therapies for ALI/ARDS to be developed.
