Abstract:

Vesikoureteral reflux, et backflöde av urin skjer från urinblåsan till uretärerna och njurbäckenet, drabbar barn. För att diagnostisera reflux används ultraljud, njurscintigrafi och främst miktionsuretrocystografi under genomlysning. Syftet var att dokumentera skillnader i undersøkning av reflux, vid en empirisk kvantitativ tvärsnittsstudie. Nio röntgenklinikers metodböcker samt deres stråldoser ble dokumentert.. Olika antal projektioner används för flickor respektive pojkar, og variasjoner i utførelsen av dem. Stråldoserna varierar; dock ses att samtliga kliniker i åldersgruppen 0–3 år har stråldoser under referensnivåerna enligt finska strålsäkerhetscentralen.

Abstract:

INTRODUCTION: The evolution of light curing units can be noticed by the different systems recently introduced. The technology of LED units promises longer lifetime, without heating and with production of specific light for activation of camphorquinone. However, further studies are still required to check the real curing effectiveness of these units. PURPOSE: This study evaluated the microhardness of 4 shades (B-0.5, B-1, B-2 and B-3) of composite resin Filtek Z-250 (3M ESPE) after light curing with 4 light sources, being one halogen (Ultralux - Dabi Atlante) and three LED (Ultraled - Dabi Atlante, Ultrablue - DMC and Elipar Freelight - 3M ESPE). METHODS: 192 specimens were distributed into 16 groups, and materials were inserted in a single increment in cylindrical templates measuring 4mm x 4mm and light cured as recommended by the manufacturer. Then, they were submitted to microhardness test on the top and bottom aspects of the cylinders. RESULTS: The hardness values achieved were submitted to analysis of variance and to Tukey test at 5% confidence level. It was observed that microhardness of specimens varied according to the shade of the material and light sources employed. The LED appliance emitting greater light intensity provided the highest hardness values with shade B-0.5, allowing the best curing. On the other hand, appliances with low light intensity were the least effective. It was also observed that the bottom of specimens was more sensitive to changes in shade. CONCLUSION: Light intensity of LED light curing units is fundamental for their good functioning, especially when applied in resins with darker shades.

Abstract:

Bakgrunn: Ultralydmåling av respirasjonsavhengige endringer i diameter av vena cava inferior kan hjelpe klinikeres vurderinger ved væskeresuscitering av hemodynamisk ustabile pasienter. Det er enkelt å gjennomføre, non-invasivt og krever lite opplæring. Studier har konkludert med at dersom sykepleiere med en avansert funksjon utfører målrettet ultralyd av vena cava inferior, kan det gi verdifull tilleggsinformasjon til kliniske vurderinger av volumstatus. Det er ikke funnet systematiske litteraturstudier som oppsummerer primærstudier der ultralyd av vena cava inferior for vurdering av volumstatus undersøkes. Hensikt: Undersøke om sykepleiere med en avansert funksjon kan utføre målrettet ultralyd av vena cava inferior for vurdering av volumstatus hos voksne pasienter. Metode: Studiens design er en systematisk litteraturstudie, med systematiske søk i databasene Cinahl, Medline, SweMed+, Cochrane Trials og Embase. Studiene ble kvalitetsvurdert ved hjelp av sjekkliste for Diagnostic Test Accuracy-studier fra Joanna Briggs Institute. Innhenting av korrekte ultralydbilder og pålitelig vurdering av volumstatus utført av sykepleiere med en avansert funksjon sammenliknet med legespesialister med ulik ekspertise på ultralyd ble analysert. Resultater: Seks studier oppfylte inklusjonskriteriene. Totalt 35 sykepleiere i avanserte funksjoner innhentet til sammen 336 bilder av vena cava inferior. For innhenting av ultralydbilder var korrelasjon mellom sykepleierne og legespesialistene moderat til utmerket. For vurdering av volumstatus var korrelasjon adekvat til utmerket. Konklusjon: Sammenstilling av funnene viste at sykepleiere med en avansert funksjon kan innhente korrekte ultralydbilder av vena cava inferior samt gjøre pålitelige vurderinger av volumstatus sammenliknet med legespesialister. Tilstrekkelig opplæring og trening er viktig.

Vor, während und nach einem 6-Tage-Lauf haben wir Körpergewicht, Hautfaltendicke, Umfänge der oberen und unteren Extremitäten sowie Energieverbrauch und Nahrungsaufnahme bei einem Athleten bestimmt. Dabei haben wir trotz einer prozentual erhöhten Einnahme von Fett und Eiweiss über die Nahrung eine deutliche Abnahme des Subkutanfetts am ganzen Körper wie auch der Muskelmasse im Bereich der belasteten Extremität bei konstantem Körpergewicht festgestellt. Wir gehen davon aus, dass beim Laufen als exzentrische Belastungsform neben Fett in Form von Subkutanfett auch Eiweiss in Form von Muskelmasse zur Energiegewinnung verbraucht wird.

Abstract:

Wir haben am Deutschlandlauf 2006 – der vom Norden Deutschlands (Kap Arkona auf der Insel Rügen) über 1200 km in 17 Tagesetappen in den Süden (Lörrach) führte – das Ernährungsverhalten von erfolgreichen Finishern untersucht. 20 erfolgreiche männliche Ultraläufer haben ihre Ernährung vor, während und nach dem Lauf bezüglich Einnahme von festen Nahrungsmitteln, Getränken sowie Ergänzungsprodukten protokolliert. Es fiel auf, dass 70% der erfolgreichen Finisher in den vier Wochen vor dem Lauf keine spezielle Diät befolgten. Vor einer Tagesetappe nahmen sie jeweils ein übliches Frühstück ein. Unter Belastung bevorzugten sie Brot, Bananen sowie Schokolade und tranken meist reines Wasser vor Apfelschorle und Coca Cola®. Am Abend nach einer Etappe nahmen sie vornehmlich Fleisch und Nudeln ein und tranken dazu reines Wasser und Bier. Multivitamin- sowie Multimineralprodukte und Magnesium waren die am meisten verwendeten Nahrungsergänzungsprodukte, wobei andere ergogene Supplemente praktisch nicht verwendet wurden.Zusammenfassend zeigte sich, dass erfolgreiche Ultraläufer am längsten Ultralauf Europas keine speziellen Ernährungsgewohnheiten aufwiesen, sondern konventionelle Nahrungsmittel vor, während und nach der Belastung bevorzugten. Der Einsatz von zusätzlichen Nahrungsergänzungsprodukten wie Vitaminen und Mineralstoffen scheint eher der Deckung eines allfälligen Defizits zu entsprechen als eine mögliche Leistungsverbesserung zu bezwecken.

Abstract:

The purpose of this study was to evaluate the microhardness of resin-based materials polymerized with a LED (light-emitting diode) light-curing unit (LCU) and a halogen LCU. Twenty cylindrical specimens (3.0 mm in diameter and 2.0 mm high) were prepared for each tested material (Z100, Definite and Dyract). Specimens were light-cured with two LCUs (Ultraled and Curing Light 2500) for either 40 or 60 s on their top surfaces. Hardness was measured on top and bottom surfaces of each specimen. Statistical analysis was done by ANOVA and Tukey's test (p<0.05). There was no significant difference in hardness between LED LCU and halogen LCU for Z100 and Dyract on top surface. Conversely, lower hardness was recorded when Definite was light-cured with the LED LCU than with the halogen lamp. On bottom surface, hardness was significantly lower for all materials light-cured with LED LCU. Z100 was harder than Dyract and Definite regardless of the light curing unit. There was no significant difference in hardness between the exposure times on top surface. Higher hardness was obtained when the materials were light-cured for 60 s on bottom surface. The tested LED was not able to produce the same microhardness of resin-based materials as the halogen LCU.

Abstract:

Clinical performance of composite resins depends largely on their mechanical properties, and those are influenced by several factors, such as the light-curing mode. The purpose of this study was to evaluate the influence of different light sources on degree of conversion (DC), Knoop hardness (KHN) and plasticization (P) of a composite resin. Disc-shaped specimens (5 x 2 mm) of Esthet-X (Dentsply) methacrylate-based microhybrid composite were light-cured using quartz-tungsten-halogen (QTH) Optilight Plus (Gnatus) or light-emitting diode (LED) Ultraled (Dabi Atlante) curing units at 400 and 340 mW/cm2 of irradiance, respectively. After 24 h, absorption spectra of composite were obtained using Nexus 670 (Nicolet) FT-IR spectrometer in order to calculate the DC. The KHN was measured in the HMV-2000 (Shimadzu) microhardness tester under 50 g loads for 15 s, and P was evaluated by percentage reduction of hardness after 24 h of alcohol storage. Data were subjected to t-Student test (alpha = 0.05). QTH device showed lower P and higher KHN than LED (p < 0.05), and no difference between the light-curing units was found for DC (p > 0.05). The halogen-curing unit with higher irradiance promoted higher KHN and lower softening in alcohol than LED.

Abstract:

The aim of this study was to assess the influence of different light-emitting diodes (LED) light-curing devices for bonding orthodontic brackets, using the shear bond strength and analysis of adhesive remnant index (ARI). Crowns from 60 bovine incisors received brackets bonded with Transbond XT. Specimens were divided into 4 groups (n=15) according to the light-curing procedures: HL = control, halogen light; OR = Ortholux LED; UL = Ultraled XP, and RD = Radii LED. All light-curing procedures were performed for 40 s. Shear bond strength test was evaluated using an universal testing machine at a crosshead speed of 0.5 mm/min. Data were analyzed statistically by ANOVA and Tukey's test. The ARI scores were evaluated with a stereoscopic magnifying glass and analyzed statistically by Kruskal-Wallis test. A significance level of 5% was set for all analyses. Shear bond strength means in MPa and standard deviations were 9.82 (3.28), 12.70 (3.35), 9.04 (2.80) and 11.22 (2.36) for HL, OR, UL and RD, respectively. OR presented the highest shear bond strength mean value. HL differed significantly (p<0.05) from Groups OR and RD. However, these groups did not differ significantly from each other (p>0.05). Regarding the ARI scores, no statistically significant difference was observed (p>0.05) among the groups. In conclusion, Ortholux LED and Radii LED units provided the highest values of bracket adhesive strength.

Abstract:

Este estudo procurou investigar o grau de dureza de um cimento resinoso dual cure (RelyX ARC - 3M ESPE) quando polimerizado sem o contato com a luz e quando fotoativado sob três diferentes materiais restauradores indiretos (Solidex-Shofu, Empress-Ivoclar, sistema In Ceram Alumina - Vita), com dois tipos de fotopolimerizadores: luz halógena (XL 1500 - 3M) e LED - light emitting diode - (UltraLed - Dabi Atlante). Foram criados sete grupos experimentais: grupo SH (Solidex Halógeno), grupo SL (Solidex LED), grupo EH (Empress Halógeno), grupo EL (Empress LED), grupo IH (InCeram Alumina Halógeno), grupo IL (InCeram Alumina LED) e grupo SCL (sem contato com a luz). Para cada grupo foram confeccionados quatro discos de cimento resinoso dual fotopolimerizados por 40 segundos, sob o material restaurador indireto, exceto para o grupo CSL onde a polimerização se deu na ausência de luz. Após 1 semana, imersos em água destilada a 37°C, os discos foram sumetidos ao teste de microdureza, em microdurômetro Shimadzu, com carga de 100g, por 15 segundos para a obtenção da dureza Vickers (VHN). Os resultados foram submetidos aos testes estatísticos de ANOVA e Tukey que demonstraram uma maior dureza superficial do grupo SH em relação a todos os outros. Os grupos SL, EH e EL não tiveram diferença estatisticamente significativa entre si, porém obtiveram valores de dureza superiores aos dos grupos IH, IL e CSL, que também não mostraram diferença estatisticamente significante entre si.

Abstract:

The clinical performance of composite resins is greatly influenced by the quality of the light-curing unit used. The aim of this study was to compare the efficiency of a commercial light-emitting diode (LED) with that of a halogen-based light-curing unit by means of dye penetration of a micro hybrid composite resin. The composite resin evaluated was Filtek Z250 (3M Dental). The composite was filled into acrylic moulds that were randomly polymerized for 40 seconds by each of the light-emitting systems: light-emitting diode Ultraled (Dabi Atlante) or halogen light Degulux (Degussa Hüls) curing units. Immediately after polymerization, each specimen was individually immersed in 1 ml of 2% methylene blue solution at 37°C ± 2°C. After 24 hours, the specimens were rinsed under running distilled water for 1 minute and stored at 37°C ± 2°C at relative humidity for 24 hours. The composite resins were removed from the moulds and individually triturated before being immersed in new test tubes containing 1 ml of absolute alcohol for 24 hours. The solutions were filtered and centrifuged for 3 minutes at 4,000 rpm and the supernatant was used to determine absorbance in a spectrophotometer at 590 nm. To verify the differences between groups polymerized by LED or halogen light t-test was applied. No significant differences were found between composite resins light-cured by LED or halogen light-curing unit (p > 0.05).
