Case ReportsRight atrial pacemaker lead thrombosis incidentally detected by transesophageal echocardiography.
In a 62-year-old man with permanent atrial fibrillation and recurrent stroke, a large right atrial thrombus attached to a permanent pacemaker lead was incidentally identified by transesophageal echocardiography. Surgical treatment, recommended because of the large dimensions of the mass, was refused by the patient, and thrombus was successfully dissolved by anticoagulant treatment. Pathogenesis of pacemaker lead thrombosis, clinical implications, diagnostic and therapeutic options are discussed.

Smoking habits, signs of chronic diseases and survival in inland and coastal regions of Croatia: a follow-up study.
Aim of the study was to estimate, the relationship between survival, smoking habits, and the results of medical examinations in inland and coastal regions of Croatia. Age and sex stratified sample of general population (1,571 men and 1,793 women, 37-56 years old in 1972; followed in 1982: N = 1,090 men; 1,325 women and/or 1972-1999 controlling vital status). Relative risks and 95% confidence limits were estimated using Cox regression in the model with time dependent covariates, separately by sex. ⋯ Survival relative risk increased with each additional smoked pack of cigarettes by 2.4% in women and 1.3% in men. Regional differences vs. smoking habit were observed. These data emphasize the need for prevention of smoking.

The role of transbronchial lung biopsy in the diagnosis of solitary pulmonary nodule.
Transbronchial lung biopsy (TBLB) is a well-recognized diagnostic technique in diffuse interstitial lung diseases, but it is not considered to be the first choice in investigation of solitary pulmonary nodules (SPN). The main idea of this study was to increase the sensitivity of bronchoscopy using multiple techniques, especially TBLB, thus to avoid more aggressive diagnostic procedures. The objective of this prospective study was to evaluate the efficacy and safety of TBLB in the diagnosis of SPN, in comparison with other bronchoscopic techniques. ⋯ Diagnostic yield improved significantly with the increasing number of specimens (less than 3 specimens: sensitivity 59%, 3 or more specimens: sensitivity 87%, p < 0.05). Complications of TBLB occurred in 2 (4%) patients: 1 incomplete pneumothorax and 1 hemorrhage. According to the results, we conclude that TBLB is an accurate and safe technique for the diagnosis of pulmonary solitary nodule with a diameter equal or greater than 25 mm.

Clinical TrialEfficacy and safety of propofol sedation during urgent upper gastrointestinal endoscopy--a prospective study.
The aim of this study was to investigate both the efficacy and safety of sedation with propofol during urgent therapeutic gastroscopy in patients with upper gastrointestinal bleeding. This prospective study included a total of 110 patients. Propofol was administered intravenously at the starting dose of 1 mg/kg body weight and was followed by repeated doses. ⋯ Potentially harmful drop in oxygen saturation below 85% was observed in 5.5% of patients, whereas a temporary drop in heart rate below 50 beats/min was observed in 11.8%, not requiring any intervention. Almost 93% of patients could not remember the beginning or the end of the intervention. This data demonstrates that sedation with propofol is suitable for use in patients with upper gastrointestinal bleeding undergoing urgent endoscopy.

Randomized Controlled Trial Clinical TrialHemodynamic differences in sevoflurane versus propofol anesthesia.
The aim of the study was to compare the effect of sevoflurane and propofol anesthesia on myocardial contractility during laparotomic cholecystectomy using transesophageal echo-Doppler. In the study, 40 patients were randomized into two groups, depending on whether they received sevoflurane or propofol anesthesia. Heart rate, cardiac index, stroke volume, left ventricular ejection time and acceleration were measured 10 minutes after induction of anesthesia, 1 minute and 25 minutes after incision. ⋯ In the propofol group changes were from 64 ml/beat to 58 +/- 10.5 ml/beat to 58 +/- 8.6 ml/beat. Stroke volume was significantly higher in the sevoflurane than in the propofol group (p < 0.05). Sevoflurane anesthesia allows a better hemodynamic stability during laparotomic cholecystectomy.
