Comparative StudyMeasuring cardiac output during dobutamine infusion after off-pump coronary artery bypass: comparison of transesophageal echo-Doppler and thermodilution.
To compare transesophageal echo-Doppler with thermodilution method for measuring cardiac output during dobutamine infusion after off-pump coronary artery bypass. ⋯ Transesophageal echo-Doppler and thermodilution can be interchangeable as methods for measuring cardiac output after off-pump coronary artery bypass.

To establish a framework for the Intensive Care Units (ICU) Register in Croatia, and examine the relation between their present organization and medical practices and their outcome performances. ⋯ Establishing a database on intensive care medicine and assessing the performance of ICUs in Croatia could serve as a model for improvement of ICU service in other transition countries.

Continuous systemic perfusion via collaterals at moderate hypothermia in aortic arch repairs in neonates.
To present our experience with modified cannulation with continuous, moderately hypothermic systemic perfusion in extensive aortic arch repair. The technique has fewer complications and preserves cerebral blood flow autoregulation. ⋯ Continuous, moderately hypothermic systemic perfusion via collaterals seems to be a method of choice in aortic arch repair in neonates. As there is no need for deep hypothermic total circulatory arrest, its numerous sequelae, such as increased postoperative bleeding and permanent neurologic deficit, can be avoided.

Right ventricle failure and outcome of simple and complex arterial switch operations in neonates.
To analyze the causes and role of right ventricle failure in the morbidity and mortality after arterial switch operation for transposition of the great arteries in neonates. ⋯ Difficult coronary anatomy was not a risk factor for morbidity and mortality after arterial switch operation. Poor preoperative health condition, hypoxia (despite effective balloon atrioseptostomy), and acidosis contributed to persistent pulmonary hypertension. Operation on the emergency basis and tricuspid valve insufficiency with right ventricle failure were strong predictors of unfavorable outcome.

According to the World Health Organization classification of neoplastic diseases of the hematopoietic and lymphoid tissues, diffuse large B-cell lymphoma comprises about 40% of adult cases of non-Hodgkin s lymphoma. It consists of the following morphological variants: 1) centroblastic (with or without multilobulated nuclei); 2) immunoblastic (>90% of immunoblasts); 3) T cell/histiocytes rich; and 4) anaplastic. Rare morphological variants plasmablastic type, mediastinal (thymic) diffuse large B-cell lymphoma, intravascular, and primary effusion B-cell lymphoma are considered distinct variants of diffuse large B-cell lymphoma due to their unique topographic presentation and clinical behavior, as well as immunophenotypic and genetic characteristics. ⋯ Twenty out of 101 patients had mediastinal B-cell lymphoma and their median survival was 21 months, with sex or degree of necrosis of the involved lymph node having no impact on survival. We studied the frequency of bcl-2 gene rearrangement in fusion with immunoglobulin receptor gene of t(14;18) and found no such event among 20 of our patients with mediastinal diffuse large B-cell lymphoma. Despite extensive efforts and constant progress in our understanding of non-Hodgkin s lymphoma pathogenesis, the diffuse large B-cell lymphoma group remains heterogeneous entity awaiting further pathological and clinical stratification.
