The discrepancy between organ availability and the increasing amount of patients on the waiting list has prompted the development of medical strategies to increase the usable organs, including the search for alternative sources of donation, organ optimization and extension of the criteria for donation. The recovery of lungs from non-heart-beating donors (NHBD) is a concept in which death is declared based on cardiopulmonary criteria rather than the currently used definition of "brain death." Obtaining NHBD lungs is currently practiced in many centers. In this review we discuss the current state of lung transplantation from uncontrolled NHBD.

Acute kidney injury (AKI) is a frequent complication in critically ill patients and is associated with high morbidity and mortality; therefore, its prophylaxis, diagnosis and intervention positively impact patient evolution. Neutrophil gelatinase-associated lipocalin (NGAL) or lipocalin, a protein synthesized by renal tubular cells, has the property to transport lipophilic molecules such as vitamins, hormones and antigenic agents. ⋯ NGAL is of the most investigated and promising biomarkers for early diagnosis of AKI in different clinical scenarios, most notably in sepsis, cardiorenal syndrome, cardiac surgery, kidney transplant, contrast nephropathy and hemolytic uremic syndrome. Lipocalin guides the early institution of therapeutic interventions to improve prognosis in AKI of several etiologies.

Review
[Massive transfusion and trauma patient management: pathophysiological approach to treatment].
Bleeding that requires massive blood transfusion is one of the main causes of cardiac arrest and death in the operating room. Its mortality varies widely between 15 and 54%, and it is strongly related to multiple factors such as acidosis, hypothermia and hypocoagulation. ⋯ A well-established response plan is needed by the surgical team and the blood bank in order to quickly facilitate blood products to the patient. Measures to avoid hypothermia and availability of rapid infusion systems are also necessary.

Review Case Reports
Trichotillomania, recurrent trichobezoar and Rapunzel syndrome: case report and literature review.
Bezoar is a conglomeration of foreign material in the intestinal tract. Trichobezoar (accumulation of hair in the gastric chamber, secondary to impulsive pulling and intake) and Rapunzel syndrome (accumulation of hair in the small intestine) usually occur in children and adolescents with trichotillomania (TTM) and trichophagia history. ⋯ TTM is characterized by recurrent and impulsive pulling of one's hair for pleasure, gratification, or relief of tension. Children and women <30 years of age are the groups who most frequently suffer from this type of disorder. Hair intake sensation was a cause for presentation of the disease. Data recollection in our environment may provide information for the determination of new information regarding the presence of this condition.

Primary repair of colon injuries is an accepted therapeutic option; however, controversy persists regarding its safety. Our objective was to report the evolution and presence of complications in patients with colon injury who underwent primary closure and to determine if the time interval (>6 h), degree of injury, contamination, anatomic site injured, PATI (Penetrating Abdominal Trauma Index) >25, and the presence of other injuries in colon trauma are associated with increased morbidity and mortality. ⋯ Primary repair is a safe procedure for treatment of colon injuries. Patients with primary repair had lower morbidity (p <0.009). Surgery during the first 6 h (p <0.006) and in hemodynamically stable patients (p <0.014) had a lower risk of complications.
