Opis:: Aim: Technologies involved in roasting coffee beans, as well as the methods used to prepare infusions, vary according to culture, and contribute to differences in the concentration of elements in the drink. Materials and Methods: Concentrations of six elements: manganese (Mn), cobalt (Co), nickel (Ni), chrome (Cr), silver (Ag) and lead (Pb) were investigated in coffee infusions from eleven samples of coffee, roasted and purchased in four countries: Bosnia and Herzegovina, Brazil, Lebanon and Poland. Metal concentrations were determined using an induction coupled plasma technique in combination with mass spectrometry (ICP-MS, Perkin Elmer) which measures total metal (ionic and non-ionic) content. Results: Metal intake estimated for individual countries (in the respective order; mean consumption per person per year) was as follows: Mn: 26.8-33.1, 28.3-29.5, 29.7, 12.6-18.9 mg; Co: 0.33-0.48, 0.42-0.35, 0.32, 0.12-0.17 mg; Ni: 3.83-5.68, 4.85-5.51, 4.04, 2.06-2.24 mg; Cr: 0.17-0.41, 0.21-0.47, 0.17, 0.09-0.28 mg; Ag: 0.16-1.13, 0.26-0.70, 0.61, 0.33-1.54 mg, Pb: 4.76-7.56, 3.59-5.13, 3.33, 1.48-2.43 mg. Conclusions: This finding gives new data for Mn, Co, Ni, Cr, and Ag intake from coffee , and suggests that the amounts are negligible. However, the data for Pb consumption in heavy drinkers, for example in Bosnia and Herzegovina, indicate that Pb intake from coffee may contribute to the disease burden. The high lead level in some coffees suggests the need for a more precise control of coffee contamination.

Opis:: Introduction. General anaesthesia can reduce child stress associated with occasionally very unpleasant dental treatment. However, general anaesthesia with endotracheal intubation is commonly used with dental procedures despite the fact that endotracheal tubes obstruct good access to molars, especially in very small children. In this article we would like to contribute to changes in anaesthetic methods to those less harsh for patients. Materials and method. At our dental practice, located at a rural area, total intravenous anaesthesia with propofol infusion, without endotracheal intubation, has been used for more than 10 years as standard procedure for the dental treatment of children. Retrospective analysis of medical records of 614 children was performed, including search for perioperative critical incidents. Results. There were two adverse events. In the first, a boy (age 10.5 years with a history of tricuspid valve regurgitation) developed severe bradycardia, with no conjunction with any desaturation. Atropine was given and heart rhythm returned to normal values. The second incident occurred during the recovery of a 4-year-old girl who developed laryngospasm after the procedure, and the decision to use rescue intubation was made. The child recovered and was extubated shortly afterwards without any further problems. These two cases account for the total perioperative critical incident rate of 0.33% (95% confidence interval ~0 to 1.3%). Conclusions. General anaesthesia without endotracheal intubation has been safe for paediatric dental treatment at our practice. Patients should be guided to follow strict fasting rules, and a throat pack and efficient suction are essential. The anaesthesiologist should be present during the intraoperative period until the child is safely discharged.

Opis:: Introduction and objective. Exercise (submaximal) in untrained subjects can modify haemostasis toward hypercoagulability, especially among women using oral contraceptives (OC). The aim of this study was to investigate whether this can be explained by platelet haemostasis and changes in the generation of membrane microparticles. Materials and method. Young, healthy women (n=60) were divided into 2 equal groups: a study group OC (+) who had used OC for >3 months, and controls who had never used oral contraceptives OC(-). Exclusion criteria: those with systematic daily physical activity. Participants were subjected to treadmill exercise (Cardiac Diagnostic System; model CH2000) using the Bruce protocol/ AHA guidelines. Platelet aggregation with arachidonic acid (ASPI test) or ADP (ADP test), membrane microparticle (MP) activity, plasma coagulation times (APTT/PT) and blood count were determined before and 45 minutes after exercise. Results. Before exercise, the OC(+) group had slightly higher platelet aggregation (ADP test), significantly lower MP activity, slightly lower PLT and slightly higher PDW rate. Exercise caused slight inhibition of platelet aggregation (ASPI test), and significant decrease in MP activity – only in the OC(-) group. After exercise, in both groups there was a significant decrease in PLT and increase in WBC, more pronounced in OC(+) group. Conclusions. Submaximal exercise was beneficial for haemostasis in women not using hormonal contraception, associated primarily with reduced MP activity. No beneficial effects of physical activity were found for women using hormonal contraceptives, possibly associated with a hypercoagulable state, and higher reactivity of blood platelets under the influence of the use of contraceptives.
