Comparative Study
Evaluation of metabolic acidosis in patients with a kidney graft: comparison of the bicarbonate-based and strong ion-based methods.
According to the traditional bicarbonate-based approach, metabolic acidosis is highly prevalent in kidney transplant recipients. However, the bicarbonate-based approach has been questioned by intensivists using strong ion difference-based methods. ⋯ The use of the SID yielded results that were similar to the traditional bicarbonate-based approach. Conversely, SIG appeared to be more sensitive than AG for detection of anion accumulation among patients with a kidney graft.

Comparative Study
Model for end-stage liver disease score versus simplified acute physiology score criteria in acute renal failure after liver transplantation.
Hepatic function and renal failure are closely related among patients with end-stage liver disease (ESLD) due to splanchnic hemodynamic mechanisms that characterize advanced decompensated cirrhosis. Acute renal failure (ARF) is a frequent complication that occurs immediately post-orthotopic liver transplantation (OLT). The Model for End-stage Liver Disease (MELD) score describes the survival of patients with ESLD awaiting OLT related to the severity of liver disease. ⋯ These patients showed significantly higher MELD scores, while there was no association with systemic parameters related to the critical patient's condition or with the mortality score as evaluated by SAPS II criteria. We confirmed the association between renal failure and hepatic function among liver transplant patients. A more severe degree of hepatic dysfunction before OLT was associated with a greater incidence of ARF that can adversely affect patient survival.

Information about brain stem death and donation can be influence the consent rate for donation and its psychosocial effects. The aim of this study was to create a "VIDEO" model that could be used to help physicians to develop communication skills. ⋯ Interaction with the family requires great preparation. The communication skills of physicians can be developed through the VIDEO model. The results can be integrated into educational programs that consider the particular features of the given country.

Liver retransplantation (Re-OLT) is one of the most debated issues in medicine over the past decade. Re-OLT, currently is accepted for patients with irreversible failure of a hepatic graft caused by primary nonfunction (PNF), hyperacute/chronic rejection, or hepatic artery thrombosis (HAT); whereas it is still controversial for patients with recurrent viral disease, in particular hepatitis C virus (HCV) cirrhosis. Patient and graft survival rates are lower than those observed after primary liver transplantation (OLT). ⋯ Comparing patients who died after liver Re-OLT versus alive patients, we did not find any significant difference in terms of mean MELD (28.6 vs 27; P=NS), MELD > 25 (60% vs 61.5%, P=NS), donor age > 60 years (30% vs 15.3%, P=NS), HCV(+) (40% vs 62%, P = NS), or time interval from OLT to Re-OLT (12.2 vs 777.7 days, P=NS). Patient survivals after Re-OLT were 67% at 3 years and 50% at 5 years, which were lower than those of first transplantations, as reported by other European and International Centers. Forty percent of deaths after Re-OLT occurred among HCV(+) recipients, but for reasons unrelated to HCV infection.

Varicella is a well-known contagious disease of childhood that can also affect both immunodepressed and immunocompetent adults. The present observations concern a previously healthy adult patient who presented with a fulminant hepatitis evolving in multiorgan failure (MOF), associated with an atypical papulo-ethemateous cutaneous rash without fever. An hepatic biopsy showed massive necrosis. ⋯ The diagnosis of liver disease from VZV should always be clinically suspected in the presence of concurrent atypical skin lesions and a temporarily immunocompromised state. Therapy with acyclovir was ineffective in our patient. Based on the wide spectrum of VZV infections, fulminant MOF in immunocompetent adults must raise the possibility of VZV with simultaneous HHV6 infection with early listing of the patient for a urgent OLT, possibly with a total hepatectomy as a bridge, due to the therapeutic uncertainty of medical treatments.
