Capsule Retentions and Incomplete Capsule Endoscopy Examinations: An Analysis of 2300 Examinations

Aim. To evaluate capsule endoscopy in terms of incomplete examinations and capsule retentions and to find risk factors for these events. Material and Methods. This retrospective and consecutive study includes data from 2300 capsule enteroscopy examinations, performed at four different hospitals in Stockholm, Sweden from 2003 to 2009. Results. The frequency of incomplete examinations was 20%. Older age, male gender, suspected, and known Crohn's disease were risk factors for an incomplete examination. The PillCam capsule had the highest rate of completed examinations. Capsule retention occurred in 1.3% (n = 31). Risk factors for capsule retention were known Crohn's disease and suspected tumor. Complications of capsule retention were acute obstructive symptoms in six patients and one death related to complications after acute surgical capsule retrieval. Conclusion: Capsule endoscopy is considered a safe procedure, although obstructive symptoms and serious complications due to capsule retention can be found in a large series of patients

Effekter av plankning : Utvecklande av solospel på piano

Improvisation är konsten att komponera, uttala, arrangera eller framställa någonting ej förberett. Hur gör man då för att lära sig musikalisk improvisation? Vanligen sker detta med hjälp av en musikteoretisk ingång. Detta arbete syftar därför till att ta reda på vad ett inlärningssätt på en gehörsbaserad grund kan ha för effekter. Metoden har varit att planka olika pianisters solon på samma låt och göra en egen inspelning, även den på samma låt både före och efter plankningen för att kunna jämföra dessa båda inspelningar och observera vilka resultat arbetet givit. Det har även gjorts en inspelning på en annan liknande låt både före och efter plankningen för att undersöka om utveckling som skett i den första låten även är överförbart till andra låtar. Resultatet tyder på att ett plankningsarbete leder till utveckling inom parametrarna timing och frasering, men att andra tillvägagångssätt är nödvändiga för att stärka sådant som rytm och tonmaterial.

Närhet och distans i instrumentalundervisning på kulturskolan

Syftet med föreliggande studie har varit att med hjälp av kvalitativa intervjuer undersöka hur sex musiklärare inom ’en-till-en’ undervisning förhåller sig till att skapa och upprätthålla en relation gentemot deras elever i kulturskolan. Tidigare studier föreslår att lärare måste upprätthålla en komplex tvådelad relation som både tillhandahåller den auktoritära- och den personliga lärarrollen. Detta sätt att betrakta lärarrollen kallas för Persona, ett begrepp som är centralt i uppsatsen. Lärarnas utsagor har analyserats med hjälp av tematisk analysmetod och temana som skapades presenteras och kopplas samman med den teoretiska utgångspunkten att lärare har två roller att upprätthålla vad gäller relationen gentemot eleven. Resultatet visar att den personliga relationen är av stor vikt för informanterna då den synliggör elevens styrkor och svagheter; således kan lärarna individanpassa undervisningen för eleverna. Denna relation skapas och upprätthålls via lärarens intresse för eleven. Detta intresse yttrar sig bland annat genom mellanmänskliga samtal under lektionerna. Dock så bör inte detta intresse vara lektionens enskilda fokus. Utifrån intervjuerna framgår det att lärarna även måste tillhandahålla mer auktoritära och opersonliga lärarroller för att eleven faktiskt ska lära sig något. Dessa två lärarroller ska alltså inte ses som dikotomier, utan ska istället användas som komplement för varandra. The purpose of this study has been to, with the help of qualitative interviews, examine how six music teachers in ’one-to-one’ tuition relate to creating and upholding a relationship in regards to their students in music schools. Earlier studies suggest that teachers must uphold a complex two-parted relationship that involves the teacher both as an authority and in a more personal role. This way of observing the teacher role is called Persona, a term central in this essay. The statements of the teachers have been analysed with the help of thematic analysis and the themes which were created are presented and connected with the theoretical perspective that teachers have two roles to uphold when it comes to the relationship towards the student. The result of the study shows that the personal relationship is of great importance for the informants as it throws light upon the students strengths and weaknesses. This makes it possible for the teachers to customize the education to fit the student. The relationship is created and upheld on the basis of interest that the teachers have for their students. This interest makes itself shown, among other ways, through interpersonal conversations during the lessons. The teachers interest in their student shouldn’t be the single focus of the lesson though. Based on the interviews, it appears that the teachers also must provide more authoritarian and impersonal teacher roles in order for the student to actually learn anything. These two teacher roles should in other words not be seen as dichotomies, but should instead be used as a complement to each other

Download date: 07. Oct. 2016 R E S E A R C H A R T I C L E Open Access Bleeding from gastrointestinal angioectasias is not related to bleeding disorders -a case control study Abstract Background: Angioectasias in the gastrointestinal tract can be found in up to 3% of the population. They are typically asymptomatic but may sometimes result in severe bleeding. The reasons for why some patients bleed from their angioectasias are not fully understood but it has been reported that it may be explained by an acquired von Willebrand syndrome (AVWS). This condition has similar laboratory findings to congenital von Willebrand disease with selective loss of large von Willebrand multimers. The aim of this study was to find out if AVWS or any other bleeding disorder was more common in patients with bleeding from angioectasias than in a control group. Methods: We compared bleeding tests and coagulation parameters, including von Willebrand multimers, from a group of 23 patients with anemia caused by bleeding from angioectasias, with the results from a control group lacking angioectasias. Results: No significant differences between the two groups were found in coagulation parameters, bleeding time or von Willebrand multimer levels. Conclusion: These results do not support a need for routine bleeding tests in cases of bleeding from angioectasias and do not show an overall increased risk of AVWS among these patients

Is tramadol associated to bleeding peptic ulcer? A nationwide case-control study in hospitalized Swedish patients.

AimsTramadol, a widely used analgesic drug, inhibits the reuptake of noradrenaline and serotonin impairing the aggregation function of thrombocytes. However, the risk for severe bleeding has previously not been studied. The aim of the present study is to investigate the association between tramadol and bleeding peptic ulcer in the Swedish population.MethodsIn this register based case-control study based on the Swedish national patient registry and prescription drug registry, we included 18 306 patients hospitalized with a first-time diagnosis of bleeding peptic ulcer. For every case, 4 matched controls were included. To investigate the temporal aspects of tramadol induced bleeding ulcer, exposure was divided into patients with newly initiated and ongoing treatment. To explore a possible confounding by indication, the effect of codeine, a drug also prescribed for the treatment of moderate pain, but not known to affect thrombocyte function, was investigated. Univariable and multivariable logistic regression was used to analyse the association between tramadol use and bleeding ulcer.ResultsTramadol was associated with an increased risk of bleeding ulcer (adjusted odds ratio (aOR) 2.1, 95% confidence interval: (2.0-2.3). The association was stronger for newly initiated treatment with tramadol 2.8 (2.5-3.2) and weaker for ongoing treatment 1.7 (1.6-1.9). Codeine was also associated with an increased risk of bleeding ulcer 1.9 (1.7-2.1) and this association was also stronger for newly initiated treatment with codeine 2.3 (2.0-2.6) and weaker for ongoing treatment 1.7 (1.5-1.9).ConclusionTreatment with tramadol was associated with an increased risk of bleeding peptic ulcer. Most of this association may be mediated by factors related to the pain condition rather than the pharmacologic effect per se
