Misunderstood: Phenomenologically Informed Research of Illness Experiences of Individuals with Pure O OCD
Even with OCD being estimated at a worldwide prevalence rate of 2%, the various manifestations of the disorder aren’t well known in modern society and the mental health fields. The purpose of this study is to examine how individuals with primarily obsessional (“Pure O”) Obsessive-Compulsive Disorder, a rarer form of OCD, access information about the disorder. Also, it investigates whether the ways OCD is portrayed in the media might hinder diagnosis for these individuals. The study’s 10 survey questions, related to individuals’ experiences of realizing their condition and accessing effective treatment, helped to generate qualitative data for analysis. It discusses the importance of recognizing how relatively-new internet chat groups, that offer the ability to freely discuss with like-minded individuals, have affected individuals’ experience of their illness. This thesis argues for the importance of trained mental health professionals who can identify “Pure O” and treat it with Exposure and Response Prevention (ERP) therapy and/or assisted medication. It also highlights the humanness of these individuals and calls for more accurate portrayals of “Pure O” in the media
Sind selbstadhäsive Komposite praxisreif?
a. Sind selbstadhäsive Füllungsmaterialien praxisreif?
Um diese Frage zu beantworten sind im Rahmen dieser Arbeit die Haftwerte eines selbstadhäsiven Füllungsmaterials mit den Haftwerten anderer Adhäsivsysteme verglichen worden.
b. Material und Methode:
Für die Durchführung der Versuchsreihe wurden 20 menschliche kariesfreie Weisheitszähne okklusal präpariert (L: 4 mm, B: 3 mm, T: 4 mm) und anschließend nach dem Zufallsprinzip in fünf Gruppen à vier Zähne aufgeteilt. Die Kavitäten wurden wie folgt vorbehandelt und gefüllt: Gruppe I Syntac TE + Empress direkt, Gruppe II: SAF à 2 x 2mm Schichten, Gruppe III: SAF als Lining + EcuSphere, Gruppe IV: Luxabond + EcuSphere, Gruppe V: Teco + EcuSphere. Anschließend wurden die Zahnwurzeln abgetrennt und die Zahnkronen mit einer Diamantsäge in 0,9 x 0,9 mm dicken Stäbchen zersägt. Die hergestellten Stäbchen wurden für drei Monate in destilliertem Wasser bei 37°C gelagert, um sie anschließend an einer Abzugmaschine anzuspannen und mittels der Microtensile-Untersuchung die Haftwerte zwischen dem Dentin und dem Füllungsmaterial zu messen. Die Adhäsivkraft (MPa) wurde aus der gemessenen Zugkraft (N) und der Querschnittfläche des Stäbchens (mm²) wie folgt berechnet: MPa = N/mm². Nach der Microtensile-Untersuchung wurden einige Proben mit dem REM untersucht, um die Frakturart zu bestimmen.
c. Ergebnisse:
Bereits während der Scheiben- und Stäbchenherstellung kam es zu Füllungsverlusten in Gruppe II und III, so dass in Gruppe II keine Stäbchen mit intakter Füllung für die Microtensile-Untersuchung verwendet werden konnten. Bei der Bestimmung der Zugkraft stellt man einen signifikanten Unterschied (p > 0,05) zwischen den Kontrollgruppen Gr. I: 18,2 ± 5,5 MPa; Gr. IV: 31,1 ± 7,7 MPa; Gr. V: 25,6 ± 8,1 MPa und den Testgruppen Gr. II: 0 MPa; Gr. III: 8,145 ± 11MPa fest.
Schlussfolgernd ist das getestete selbstadhäsive Füllungsmaterial noch nicht praxisreif, denn es hat sich weder als selbstadhäsives Füllungsmaterial noch als Lining erweisen können

Differences in Relative Hippocampus Volume and Number of Hippocampus Neurons among Five Corvid Species
The relative size of the avian hippocampus (Hp) has been shown to be related to spatial memory and food storing in two avian families, the parids and corvids. Basil et al. [Brain Behav Evol 1996;47: 156-164] examined North American food-storing birds in the corvid family and found that Clark’s nutcrackers had a larger relative Hp than pinyon jays and Western scrub jays. These results correlated with the nutcracker’s better performance on most spatial memory tasks and their strong reliance on stored food in the wild. However, Pravosudov and de Kort [Brain Behav Evol 67 (2006), 1-9] raised questions about the methodology used in the 1996 study, specifically the use of paraffin as an embedding material and recalculation for shrinkage. Therefore, we measured relative Hp volume using gelatin as the embedding material in four North American species of food-storing corvids (Clark’s nutcrackers, pinyon jays, Western scrub jays and blue jays) and one Eurasian corvid that stores little to no food (azure-winged magpies). Although there was a significant overall effect of species on relative Hp volume among the five species, subsequent tests found only one pairwise difference, blue jays having a larger Hp than the azure-winged magpies. We also examined the relative size of the septum in the five species. Although Shiflett et al. [J Neurobiol 51 (2002), 215-222] found a difference in relative septum volume amongst three species of parids that correlated with storing food, we did not find significant differences amongst the five species in relative septum. Finally, we calculated the number of neurons in the Hp relative to body mass in the five species and found statistically significant differences, some of which are in accord with the adaptive specialization hypothesis and some are not

Double vs single internal thoracic artery harvesting in diabetic patients: role in perioperative infection rate
Background: The aim of this prospective study is to evaluate the role in the onset of surgical site infections of bilateral internal thoracic arteries harvesting in patients with decompensated preoperative glycemia. Methods: 81 consecutive patients with uncontrolled diabetes mellitus underwent elective CABG harvesting single or double internal thoracic arteries. Single left ITA was harvested in 41 patients (Group 1, 50.6%), BITAs were harvested in 40 (Group 2, 49.4%). The major clinical end points analyzed in this study were infection rate, type of infection, duration of infection, infection relapse rate and total hospital length of stay. Results: Five patients developed sternal SSI in the perioperative period, 2 in group 1 and 3 in group 2 without significant difference. All sternal SSIs were superficial with no sternal dehiscence. The development of infection from the time of surgery took 18.5 ± 2.1 and 7.3 ± 3.0 days for Groups 1 and 2 respectively. The infections were treated with wound irrigation and debridement, and with VAC therapy as well as with antibiotics. The VAC system was removed after a mean of 12.8 ± 5.1 days, when sterilization was achieved. The overall survival estimate at 1 year was 98.7%. Only BMI was a significant predictor of SSI using multivariate stepwise logistic regression analysis (Odds Ratio: 1.34; 95%Conficdence Interval: 1.02–1.83; p value: 0.04). In the model, the use of BITA was not an independent predictor of SSI. Conclusion: CABG with bilateral pedicled ITAs grafting could be performed safely even in diabetics with poor preoperative glycaemic control
