We have developed a technique for autotransfusion of shed mediastinal blood collected in the cardiotomy reservoir. Results in the first 50 consecutive patients in whom the system was employed were studied prospectively (group A) and were compared with those of the last 50 consecutive patients operated on before application of the new method (group B). The(More)
The allergic reaction begins with the antigen-induced aggregation of occupied high-affinity IgE receptors expressed on mast cell surface, their activation, and the release of proinflammatory mediators that cause the "early phase" of this process. In addition, mast cell activation induces the onset of a "late phase" reaction characterized by the tissue(More)
Mast cells have a clear-cut pathologic role in allergy, participating in a number of chronic inflammatory conditions, in helmintic parasitosis, and in some solid tumor reactions, but also in physiological situations, such as wound healing and innate immunity. Mast cells release a large number of proinflammatory, immunoregulatory, and tissue regulatory(More)
Plasma levels of biologically active IL-1, tumour necrosis factor (TNF) and IL-6 were measured before, during and after coronary artery bypass graftings (CABG) (n = 9) and cholecystectomy (CHO, n = 9), and in normal controls (nine healthy volunteers). Mean pre-operative IL-1 concentration in four of the nine CABG patients was 0.452 + 0.03 ng/ml,(More)
We retrospectively analyzed the data of 119 patients who were treated for empyema thoracis from 1999 to 2007. There were 87 men with a mean age of 63.9 years (range, 19-79 years) and 32 women with a mean age 55.2 years (range, 26-78 years). The empyema was right-sided in 73 patients and left-sided in 46. The etiology was parapneumonic in 43.7% of cases,(More)
The effects of perioperative administration of magnesium sulfate on myocardial function was studied in patients with unstable angina (grade IV) undergoing coronary artery bypass grafting. Myocardial protection consisted of antegrade and retrograde continuous warm blood cardioplegia. Patients were randomly divided into two groups. Group A (50 patients)(More)
BACKGROUND Lung cancer is the commonest cause of cancer death in developed countries. Adenocarcinoma is becoming the most common form of lung cancer. Cigarette smoking is the main risk factor for lung cancer. Long-term cigarettes smoking may be characterized by genetic alteration and diffuse injury of the airways surface, named field cancerization, while(More)
BACKGROUND Fractures of the sternum may be associated with major injuries to thoracic organs, with serious consequences. OBJECTIVE To assess the hospital course of patients diagnosed with isolated sternal fracture. METHODS We reviewed 55 medical records of patients who were admitted with isolated sternal fracture to the emergency department during the(More)
Recurrent spontaneous pneumothorax often requires surgical intervention. Recently, less invasive thoracic surgical techniques, such as video-assisted thoracoscopy (VAT) and limited axillary thoracotomy (LAT), have been developed and used for different thoracic procedures. We describe our results with limited axillary thoracotomy, as compared with those of(More)
