The purpose of this study was to test the hypothesis that more recently developed rubber dam systems (OptraDam ® Plus and OptiDam™) are faster and easier to handle, and that the quality of isolation is not decreased. The rubber dam systems were applied in standard conditions on a dental simulator in several model clinical situations. The time of preparation, application and removal were measured and the quality of isolation was evaluated. The median time of rubber dam placement was 51 s (Q1 = 38 s; Q3 = 79 s). The shortest median time of application was with OptiDam™ (42 s), followed by a conventional rubber dam (53 s), and finally the longest was with OptraDam® Plus (58 s). The median volume of fluid remaining in the isolated space after 5 minutes was 9.5 mL (Q1 = 8 mL; Q3 = 10 mL). The largest median volume of remaining water was with OptiDam™ (10 mL), followed by a conventional rubber dam (9.5 mL) and the least with OptraDam® Plus (8.5 mL). The afore-stated hypothesis about the advantages of modern rubber dam isolation systems was accepted for OptiDam™, but rejected for OptraDam® Plus. The results could contribute to decision-making concerning the choice of rubber dam system. and Martin Kapitán, Zdeňka Šustová, Romana Ivančaková, Jakub Suchánek
The aim of this study was to compare the isolation systems OptraDam® Plus and OptiDam™ with the conventional rubber dam in terms of objective and subjective parameters. The isolation systems were applied during the dental treatment of the patients. The time of preparation, placement, presence and removal were measured and the quality of isolation was evaluated. The median time of rubber dam placement was 76 s (Q1=62 s; Q3=111.25 s). The application time of OptraDam® Plus was significantly longer compared to the other systems (P ® plus. The results presented in this study could guide clinicians for choosing the most appropriate isolation system. and M. Kapitán, T. Suchánková Kleplová, J. Suchánek
Akutní krvácení do horní části gastrointestinálního traktu je život ohrožující situace vyžadující rychle a správně zvolený diagnostický postup s verifikací zdroje krvácení a pokud možno s efektivní hemostázou. Vedle dlouhodobě zavedených možností endoskopické hemostázy (opich adrenalinem, hemostatické klipy) se v poslední době setkáváme s několika novými technologiemi při zástavě krvácení., Acute upper gastrointestinal tract bleeding is a life-threatening incident in which a right diagnostic and therapeutic approach is necessary. Beside the standards in endoscopic hemostasis (adrenalin injection, hemostatic clips) there are some new technologies in endoscopic hemostasis., and Radan Keil, Ladislav Douda
Pacienti s diabetem 1. typu jsou vystaveni neustálé zátěži vyplývající z nutnosti pečlivého selfmonitoringu glykemie a přesného dávkování inzulinu na základě zjištěných hodnot, obsahu sacharidů v potravě a plánované i neplánované fyzické aktivity. Chyby při dávkování inzulinu se projeví hypoglykemií nebo hyperglykemií, přičemž výskyt hypoglykemií je nejčastějším faktorem limitujícím dosažení optimální kompenzace diabetu. Proto jsou pokroky při vývoji automatických prvků pro dávkování inzulinu v inzulinových pumpách velmi významné i z klinického hlediska. V současnosti dostupné systémy LGS a PLGM umožňují omezit výskyt a dobu strávenou v hypoglykemii a jsou dalším krokem na cestě k uzavřenému okruhu dávkování inzulinu., Patients with type 1 diabetes are exposed to permanent burden consisting of careful glucose self-monitoring and precise insulin dosage based on measured glucose values, carbohydrates content in the food and both planned and non-planned physical activity. Erroneous insulin dosing causes frequent both hypoglycemia and hyperglycemia. Hypoglycemia is, however, the most clinically significant complication limiting the optimal diabetes control. Automatic features for insulin dosage integrated in insulin pumps are thus very important. Low glucose suspend (LGS) and Predictive Low Glucose Management (PLGM) use glucose sensor values to prevent hypoglycemia, shorten the time spent in hypoglycemic range and present further step forward to fully closed-loop system of insulin treatment., and Martin Prázný
