BACKGROUND We designed this study to determine the value of serum levels of several cardiac markers in patients who underwent radiofrequency ablation and to establish the utility of cardiac troponin I (cTnI). After radiofrequency ablation there is always a small localized endomyocardial necrosis. The volume of the necrosis may be estimated by the rise of(More)
Adenosine deaminase activity (ADA) determination in cerebrospinal fluid (CSF) is considered a specific test for the diagnosis of tuberculous meningitis. In order to study the variability of this marker in patients with different neurological disorders associated with HIV infection, and its utility for the diagnosis of tuberculous meningitis in these(More)
Radiofrequency (RF) catheter ablation is the curative treatment of choice for many cardiac arrhythmias. After RF ablation there is always a small localized endomyocardial necrosis, necessary to abolish the arrhythmia. We designed this study to determine the serum concentrations of several cardiac markers in patients who underwent RF catheter ablation. The(More)
We analysed the efficacy of pleural adenosine deaminase (ADAp) and the ADA1/ADAp ratio in the diagnosis of pleural tuberculosis in 103 pleural effusions, 27 of which were tuberculosis (TB) and 76 other diagnoses (non-TB). Smears, cultures and pleural biopsies were carried out in all cases, and were used for final diagnosis. The diagnostic yield of the(More)
INTRODUCTION Ca-125 is secreted by different celomic epitheliums. Serum levels may be increased in malignant diseases, like ovarian cancer but also in other medical conditions, such as pulmonary and extrapulmonary tuberculosis. METHODS From Jan-04 to Dec-06 a retrospective study analyzing Ca-125 levels in serum samples from patients with a diagnosis of(More)
INTRODUCTION A prospective study has been carried out in 33 children with congenital heart disease, aged 5 days to 16 years, operated on with the aid of cardiopulmonary bypass (CPB), in order to evaluate intra and postoperative glycemia in relation to children's weight and intra-CPB perfusion temperature. MATERIAL AND METHODS Plasmatic levels of glucose,(More)
INTRODUCTION Studies on biomarkers in tuberculosis are focused on pulmonary forms of this disease (PTB), and only limited information is currently available on biomarkers of extra-pulmonary tuberculosis (EPTB). METHODS Serum samples from 24 patients with PTB, 29 patients with EPTB and 27 healthy controls were obtained, and the levels of interferon-gamma,(More)
Various abnormalities have been described in platelets of patients with Essential Thrombocythemia (ET), including alteration in the glycolytic pathway and increased lactate production. Lactate dehydrogenase (LDH) isoenzymes were studied in 15 of these patients. Relative activity of LDH-5 isoenzyme was higher comparing with normal platelets (p < 0.05), while(More)
The use of extrinsic PEEP (PEEPe) in patients with auto-PEEP (AP) can reduce the respiratory work during weaning from mechanical ventilation. However, the application of PEEPe can produce a certain level of hyperinflation, an undesirable effect which can limit the efficacy of the reduction of respiratory work. The objective of the present study has been to(More)
