Abstract:  A pelvic cake kidney with hydronephrosis and renal failure with the single draining ureter was reported. Frequent urination related to compression of the bladder was the most important symptom. The kidney was craniolaterally displaced, the malfunctioning ureter was replaced with the Boari‐like tubularization of the bladder, and the neoureter was anastomosed with the calyx. The bladder was enlarged by intestinal augmentation.

Introduction: As one of the most important dental diseases, caries cannot be treated with classic therapeutic measures, but very often, there is a need for preventive and prophylactic measures. Aim: The aim of this study was to assess clinical efficiency of composite materials and glass-ionomer cements as pit and fissure sealants in caries prevention. Materials and Methods: The study comprised 50 patients (141 teeth), both sexes, 6-7 years old with at least two erupted first permanent molars. The main diagnostic criterion was smooth enamel surface with no probe faltering on the tooth. Materials tested in this study were two composite materials (Heiloseal-Opak and Helioseal-Transparent) and two glass-ionomers (Fisurit and Fuji VII). For clinical assessment of these materials, modified Cvar-Ryge criteria were used. Results: The obtained results showed no statistically significant differences among materials in respect to retention, marginal adaptation, discoloration and secondary caries. The difference was significant in respect to surface roughness between Fuji VII and Fisurit and Fuji VII and Helioseal-Opak (p<0.05). Conclusion: Composite sealant Heiloseal-Opak and glass-ionomer Fuji VII showed better clinical results in respect to all tested parameters compared to Helioseal-Transparent and Fisurit. .

BACKGROUND Co-induction in anesthesia is very useful: synergistic effects of two inductional drugs may lower the dose regimen and the incidence of adverse effects. The aim of this study was to investigate and compare two anesthesiological techniques for short-lasting gynecological procedures in outpatient anesthesia. A total of 80 patients scheduled for surgical termination of pregnancy were randomly assigned into two equal groups--control and co-induction group. METOHDS: The first group of patients received atropine 0.5 mg i.v., alfentanil 0.5 mg i.v. and propofol as a fractionated i.v. bolus until the loss of eyelash reflex. The second group received atropin 0.5 mg, alfentanil 0.5 mg, midazolam 3 mg and propofol in the same manner as the first group. Anesthesia was maintained with propofol increments. Cardiovascular parameters, parameters of post anesthesia recovery and the adverse effects were registered. RESULTS In patients receiving midazolam inductional dose of propofol was significantly lower, whereas cardiovascular parameters were not significantly different. The recovery after anesthesia was slightly longer after co-induction, but it was not of great clinical significance. The reduction of the adverse effects was found in the co-induction group. CONCLUSION The results of the study showed that co-induction of midazolam-propofol in comparison with propofol alone for outpatient anesthesia had the following advantages: the reduction of propofol dose, better quality of anesthesia and the reduction of the adverse effects. Recovery was faster in the group that didn't receive midazolam, but it was not of great clinical significance. The conclusion is that co-induction with the combination midazolam-propofol has the advantage in outpatient procedures.

Recently, the dental filling material amalgam has again been a target of criticism, especially within the mass media. The controversy has been further fueled by the combination of the patients' desire for fillings to match tooth colouring and this latest wave of artificially created fear of the poison mercury. The investigation submitted here is seen as a contribution toward clearing up the issue of any risk. Using flameless atom absorption spectroscopy, blood and urine samples were taken from four test groups and examined for their mercury content. Two of the participating groups tested (dentists and assistants) were actively processing mercury while the other two, one with and one without amalgam fillings, served as control groups. In the daily preparation of amalgam, dental staff working in the dental office were subject to greater exposure to mercury vapours. Their blood readings, therefore, were double those of the control group, while their urine readings were much higher than those for people not working with mercury. The two control groups (with and without amalgam fillings) showed no significant difference in mercury levels, which implies that these slight traces of mercury can be attributed to food and the environment. Although the mercury readings of the dental office personnel were twice as high as that of the control group, there was no threat of mercury poisoning for any of the four groups. The continued use of amalgam fillings in teeth can be recommended without reservation and at no risk to the patient. Particular measures must be taken to guarantee the safety of office staff.
