Case ReportsPost-transplantation lymphoproliferative disorder in pediatric patient.
Immunosuppressive therapy for transplanted patients exposes them to a high risk of developing posttransplantation lymphoproliferative disorders (PTLD). We report the case of a child undergoing heart transplantation at seven months of age who developed PTLD at nine years of age, diagnosed by resection of a pulmonary nodule.

Hemodynamic and vascular endothelium function studies in healthy pigs after intravenous bolus infusion of methylene blue.
Clinical benefit of methylene blue (MB) treating NO-induced vasoplegia has been reported in sepsis, systemic inflammatory response syndrome (SIRS) in cardiac surgery and anaphylactic shock, but its safety is sometimes questioned, mainly regarding its hemodynamic effects and the possibility of causing endothelium dysfunction. To examine the nitric oxide plasma levels and cardiovascular effects of the infusion of MB in vivo and its effects on endothelium-dependent and endothelium-independent in vitro vascular relaxation. ⋯ Intravenous use of MB, at the investigated dose, did not cause any abnormal hemodynamic responses or impairment of endothelium-dependent relaxation.

Comparative StudySevere heart failure at intensive therapy unit--is there an ideal prognostic index?
To assess the applicability of three prognostic indexes--APACHE II, SAPS II and UNICAMP II--in a subgroup of critical heart failure (HF) patients. ⋯ The three prognostic indexes under study did not prove to be appropriate for the assessment of cardiopathy patients at Intensive Care Unit (ICU). For HF patients, PTE played a major role in mortality of heart failure. Specific prognostic indexes for cardiopathy patients with severe HF should be proposed, and the discussion on anticoagulation on those patients should be expanded.

C-reactive protein diagnostic and prognostic value in patients presenting at the emergency room with chest pain.
To test immediate diagnostic and prognostic values of C-reactive protein (CRP) in patients admitted to the emergency room (ER) with chest pain (CP) without ST-segment elevation on the electrocardiogram (ECG). ⋯ In patients with chest pain presenting at the emergency room, s-CRP was not a good marker of AMI, although this diagnosis is virtually excluded by a normal value; in addition, values one-third above the upper limit of normal (>1 mg/L for hs-CRP or >0.33 mg/dL for t-CRP) were predictive of in-hospital adverse cardiac events.

[Predictors of in-hospital lethality in patients with advanced heart failure].
Describe the clinical characteristics and identify potential risk factors for in-hospital lethality in patients with decompensated heart failure admitted to an intensive care unit. ⋯ Patients admitted to an intensive care unit due to decompensated heart failure have high in-hospital lethality. In this study, variables recorded at admission, such as previous stroke, atrial fibrillation, hyponatremia, renal failure, and age > 70 years were predictors of in-hospital lethality.
