Oncocytic Schneiderian papilloma (OSP) is one of the three morphologically distinct tumors that arise from Schneiderian membrane (the others include exophytic papilloma and inverted papilloma). OSP almost always occurs unilaterally in the paranasal sinuses, usually in the maxillary sinus, ethmoid cells or sphenoid sinus. We report a case of a 64-year-old woman with OSP arising from the left frontal sinus. In the report herein, we describe an OSP originating in the region of frontal sinus, which, to the best of our knowledge, represents the first documented example in English literature of OSP developing in this anatomical site. and D.

Zkoumali jsme jak efektivněji využít zdroje a příležitosti, které máme k dispozici, abychom více publikovali a aby výstupy byly kvalitnější. Obhajujeme opatření pro zvýšení efektivity, jakým je soustředění se na konkrétní oblasti výzkumu, zahraniční publikace, nahrazení monografi í doktorandů a habilitací publikováním článků v mezinárodních časopisech, vzděláváním výzkumných pracovníků, vyhledáváním mladých talentů a mezinárodních partnerů. Všechna tato opatření lze zavést bez zásahu zvnějšku., We explored what can be done with more effi cient use of the resources and opportunities we already have such that we produce more output and more high quality output. We advocate measures for improving effi ciency, such as focusing on certain research fi elds, publishing internationally, replacing monographs for PhD students and habilitation, by publishing international articles, educating researchers by establishing graduate schools, selecting young talent and fi nding international partners. All of these measures can be taken without external interference., Assoc. Prof. Jitse P. van Dijk MD PhD, and Literatura
Hlavní cíl: Zjistit vliv procvičování ošetřovatelského procesu podle OPT modelu klinické rozvahy na erudici studentů oboru všeobecná sestra při využívání pojmů Aliance 3N. Východiska: Motivem k realizaci studie bylo dílo autorek OPT modelu klinické rozvahy Pesut a Herman a výzkumné články k OPT modelu autorů Bartlett et al., Bland et al. a Kautz et al. Metodika: Aplikován byl design přirozeného experimentu u dvou skupin studentů s použitím pretestu a posttestu. Výzkumné nástroje byly nově pro tuto studii připraveny na podkladě publikovaných článků Herman a Bartlett. Jednalo se o pracovní protokoly pro studenty a nástroj k hodnocení erudice klinické rozvahy. Proběhla obsahová validizace protokolů a u hodnotícího nástroje byla ověřena reliabilita. Sběr dat proběhl u souboru šedesáti tří studentů formou záznamů do pracovních protokolů. Data, extrahovaná z protokolů, byla zpracována na hladině signifi kance 0,05 pomocí Studentova párového t-testu a Wilcoxonova párového testu. Výsledky: Medián celkového skóre erudice klinické rozvahy byl, při maximálním dosažitelném počtu 29 bodů, u studentů prezenční formy v pretestu 18,9 a v posttestu 19,5 bodů. U kombinované formy byl před a po cvičení 18,0 a 17,0 bodů. Závěry: U prezenční formy studia byla erudice klinické rozvahy s pojmy Aliance 3N po procvičování zlepšena, ale rozdíl nebyl statisticky signifi kantní. U kombinované formy studia prokázal Wilcoxonův párový test signifi kantní zhoršení. Využití NANDA diagnóz bylo u obou skupin subjektů explicitní, zásadní nedostatky byly shledány ve volbě optimálních NOC a NIC., Main aim: To determine the effect of practicing nursing process by OPT model of clinical reasoning on the expertise of students of General Nursing study in the use of concepts Alliance 3N. Background: The motive for the study was the work of the OPT model of clinical reasoning authors Pesut and Herman and research articles on the OPT model, the authors Bartlett et al., Bland et al. and Kautz et al. Methods: Applied design was a natural experiment on two groups of students using pretest and posttest. Research instruments for this study were new and prepared on the basis Herman and Bartlett’s published articles. Th ese were working protocols for students and a tool to assess erudition of clinical reasoning. Content validation was carried out and evaluation tool was tested on reliability. The data were collected in a group of sixty-three students in the form of records to work protocols. The data extracted from the protocols were processed at 0.05 level of signifi cance using Student’s paired t -test and Wilcoxon paired test. Results: The median of total score sheet clinical erudition was at full-time students in the pretest (before practicing) 18.9 points aft er exercise 19.5 (posttest). The median of total score before and aft er exercise was 18.0 and 17.0 points at part-time study students. Conclusions: For full-time students’ erudition in clinical reasoning with 3N Alliance terms aft er exercises has improved, but the diff erence was not statistically signifi cant. For part-time study students Wilcoxon paired test showed a signifi cant deterioration in student achievement. Use of NANDA diagnoses in both groups of subjects was explicit, major fl aws were found in the choice of optimal NOC and NIC., Jana Marečková, Soňa Bocková, Petra Stefanová, Lenka Mazalová, Radka Matějková, Jana Zapletalová, and Literatura
Background Patent ductus arteriosus (PDA) is common in very premature infants. Pharmacological closure of PDA with indomethacin, a prostaglandin inhibitor, has remained the mainstay of treatment in premature infants over the last three decades. Intravenous ibuprofen was recently shown to be as effective and to have fewer adverse reaction in preterm infants. If equally effective, then oral ibuprofen for PDA closure would have several important advantages over the intravenous route. This study was designed to assess the efficacy and safety of oral ibuprofen and intravenous ibuprofen for the early pharmacological treatment of PDA in LBW preterm infants with respiratory distress syndrome. Methods A randomized, single-blinded, controlled study was performed on premature neonates at the neonatal care unit of the University Hospital for Obstetrics and Gynecology”Koco Gliozheni”, Tirana, Albania, from January 2010 to December 2012. The study enrolled 68 preterm infants with gestational age between 28-32 weeks, birth weight ≤ 2000 g, postnatal age 48-96 h, and had echocardiographically confirmed significant PDA. The preterm infants received either intravenous or oral ibuprofen randomly as an initial dose of 10 mg/kg, followed by 5 mg/kg at 24 and 48 h. After the first dose of treatment in both groups, echocardiographic evaluation was performed, to determine the need for a second or third dose. The rate of ductal closure, adverse effects, complications, and the patient’s clinical course were recorded. Results All patients were born after 28 until 32 weeks’ gestation. 36 patients were treated with oral ibuprofen and 32 with intravenous ibuprofen in this period. After the first course of the treatment, the PDA closed in 30 (83.3%) of the patients assigned to the oral ibuprofen group versus 23 (71.8%) of those enrolled in the intravenous ibuprofen group (p = 0.355). There was no difference between treatment groups in demographics or baseline renal function. In the evaluation of renal tolerance, none of the patients had oliguria. There were no significant differences with respect to complications during the stay. Conclusions In low birth weight infants, the rate of early ductal closure with oral ibuprofen is at least as good as with the intravenous route. Oral ibuprofen is associated with fewer adverse effects, Alketa Hoxha, Ermira Kola, Numila Kuneshka, Eduard Tushe, and Literatura
