- BACKGROUND: A subgroup of patients with chronic cough is recognised as having airway symptoms resulting exposure to chemicals and scents related to enhanced cough sensitivity to inhaled capsaicin. Sensory hyperreactivity, which has an estimated prevalence of more than 6%, is one possible explanation for the symptoms experienced by these patients. We hypothesized that a number of patients diagnosed with chronic unexplained cough also have coughing provoked by chemical irritants associated with augmented capsaicin cough reaction, but the extent of such a relation is not known. One aim of the present study was to analyse cough sensitivity to inhaled capsaicin in patients with chronic unexplained cough. Another aim was to compare capsaicin sensitivity in individuals with chemically induced coughing (the chemical-sensitive group) to capsaicin sensitivity in those without such chemical sensitivity (non-sensitive group). METHODS: Fifty-six participants from an earlier cross-sectional study of 62 patients with chronic unexplained cough were asked to participate in this study: 33 were chemical-sensitive and 23 were non-sensitive. Each participant visited the clinic once and performed a capsaicin inhalation test with one of two inhalation devices. The number of coughs, induced airway symptoms, and spirometry results were recorded. RESULTS: Thirty-nine of the invited patients participated in the study, with 32 in the chemical-sensitive group (21 women, 11 men), and 7 in the non-sensitive group (4 women, 3 men). The chemical-sensitive patients coughed significantly more on inhaling capsaicin, and had significantly more other airway symptoms compared to those in the non-sensitive group. Women coughed significantly more than men after receiving the higher concentration of capsaicin. CONCLUSIONS: Environmental irritants often trigger chronic unexplained cough. The current findings confirm that this sensitivity is related to enhanced capsaicin cough sensitivity and indicates more involvement of airway sensory nerves in the pathophysiology of the disease than in cough without evident trigger factors.

- Objective. The aim of the study was to examine the fracture strength of fully anatomical monolithic high translucent Y-TZP, yttria-stabilized tetragonal zirconia polycrystal, crowns and to compare them with monolithic low translucent Y-TZP crowns in different thicknesses. Materials and methods. 80 standardized crowns were made out of a master model resembling a first mandibular molar made in composite material; 40 crowns made of Lava Zirconia by 3M ESPE, a monolithic low translucent Y-TZP material, and 40 crowns made of Lava Plus by 3M ESPE, a monolithic high translucent Y-TZP material. In each group ten crowns of the thicknesses 1.0 mm, 0.7 mm, 0.5 mm and 0.3 mm were made. All crowns underwent thermocycling and preload to simulate aging and normal wear. Finally the specimens were placed in a testing jig and underwent load to fracture. Results. No significant difference was found when comparing the two materials. When comparing the materials in each thickness a significant difference was found in the 0.5 mm group where the high translucent YTZ-P had a higher mean fracture strength value. A significant difference was seen between the different thicknesses within both groups. The strength increased with added thicknesses. Conclusions. The low translucent and high translucent monolithic YTZ-P perform equally well. The use of high translucent monolithic Y-TZP could result in more aesthetic results and the minimal invasive preparation could lead to a reduction in biological complications. This could be beneficial for the patient since the results suggest that even a thin restoration sustains reasonable load in an in vitro environment. Clinical studies are needed to confirm this suggestion.

Gender differences in self-assessment among dental students at an ”Objective Structured Clinical Examination (OSCE).
- 2014
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Objective: The objective of this study was to compare dental student’s real/practical results at an Objective Structured Clinical Examination (OSCE) with their self-assessed results. These results were compared depending on gender. Introduction: There are several studies published comparing differences in self-assessment between women and men in theoretical exams. However, knowledge is lacking in regards to clinical examinations. At theoretical examinations, it has been found that men tend to over-estimate their performance more frequently than women do. Whether these differences in self-assessment exist because men tend to over-estimate themselves, women tend to under-estimate themselves, a combination of both or that self-assessments actually are consistent with the results at the examination, vary between different studies. Materials and methods: All students (35 women and 16 men) at the sixth semester at Malmö Dental School were examined with an OSCE with 13 stations. The student’s real results at OSCE were compared with their self-assessment at each station. The assessments were compared regarding gender. Results: At most of the 13 stations there were no significant differences in over- and under-estimation regarding women and men. It was more difficult for men to assess their performance regarding impression with alginate. These misjudgments were mainly caused by over-estimation. There were no results indicating that women under-estimate their performance at greater extent than men. Conclusion: Contrary to studies where gender differences concerning self-assessment in theoretical examinations are observed, the present study found no significant differences in over- and under-estimation between women and men.

- Målsättningen med studien var att jämföra implantat-stödda partiella broar av titan-porslin respektive yttria-stabiliserad zirkoniumdioxid med ytporslin. Sexton patienter fick sammanlagt 18 broar; 8 av titan-porslin och 10 av yttria-stabiliserad zirkoniumdioxid-porslin. Broarna fördelades randomiserat till respektive material-grupp. Patienterna följdes upp och kontrollerades en första gång efter 3 månader och därefter en gång per år. Ett bedömningsprotokoll baserat på California Dental Association (CDA) kriterier användes. Alla patienter genomförde kontrollbesöken. Genomsnittlig uppföljningstid var 15,2 månader (12-24 månader). Alla konstruktioner var i funktion vid uppföljning och alla patienter var nöjda med behandlingen. Inga tekniska komplikationer noterades i någon av grupperna. Biologiska komplikationer av ringa betydelse, plack och/eller mucosit, som inte påverkade konstruktionernas överlevnad noterades vid 6 av titan-keramik broarna och 2 av zirkonia-porslins broarna. Skillnaden var inte statistiskt signifikant. Sammanfattningsvis kan vi i denna studie konstatera att båda materialen fungerade jämförbart. Data från denna studie antyder att implantat-stödda partiella broar av titan-porslin respektive zirkoniumdioxid med ytporslin uppvisar goda resultat över kort sikt. Studier med fler patienter och längre uppföljningstid rekommenderas emellertid innan definitiva slutsatser kan dras.

- This study evaluated the effect of a family-based multifactor intervention programme on physical activity among overweight or obese children. Children (n = 105, mean age 10.6 ± 1.07 years) with overweight or obesity were randomized into an intervention or control group. The intervention group participated in a 1-year programme aiming at lifestyle changes regarding food habits and physical activity. All children's physical activity was measured using SenseWear Armband at baseline and after 1 year. The children in both groups had a physical activity level (PAL) of 1.67 (0.27) at baseline. When comparing the intervention and control groups, no significant differences were found in physical activity outcome variables after 1 year of intervention. Contrarily to the hypotheses, both groups decreased their energy expenditure and time spent at >3 MET, and there was no change in steps and screen time after 1 year. Despite extensive efforts, the intervention showed no significant positive effect on overweight and obese children's PAL. Further studies are needed to obtain more knowledge on how to maintain or increase the PAL successfully among overweight and obese children.Read More: http://informahealthcare.com/doi/abs/10.3109/14038196.2011.566353

- The aim was to examine the effect on physical activity of a 2-year family-based lifestyle intervention among overweight and obese Swedish children 8–12 years of age; 105 children were randomized to either intervention or control group. The intervention group was offered a 2-year lifestyle programme. Physical activity was measured using SenseWear Pro2 Armband during 4 consecutive days before and after the intervention. When comparing the intervention and control groups, no significant differences were found in the physical activity outcome variables after 2 years of intervention. However, the intervention group decreased their number of steps per day by 13%, p = 0.003 but had an unchanged screen time, whereas the control group had an unchanged number of steps but increased their screen time by 15%, p = 0.02, from baseline to 2-year measurement. There were no significant change in the intervention group, whereas significantly fewer children in the control group achieved the physical activity recommendations at 2-year measurement (88%) compared with at baseline (98%), p = 0.007. Future interventions regarding physical activity among overweight and obese children are of great importance even though the present one showed limited effects. In the continuing work, a greater effect may be received with an extended and more intense intervention regarding physical activity, focusing on reducing sedentary time rather than increasing the physical activity level.Read More: http://informahealthcare.com/doi/abs/10.3109/14038196.2011.562540
