- The purpose of this study was to investigate how different amounts of visual assessment information influence the recommended treatment for velopharyngeal insufficiency (VPI). Is a patient presented with videofluoroscopy (VF) in lateral projection recommended the same treatment as when frontal projection, nasoendoscopy, or both, are added? Retrospective material with video recorded assessment of VPI was blinded and copied in random order. Each patient was then presented in four separate combinations: VF in lateral projection; VF in lateral and frontal projection; VF in lateral projection and nasoendoscopy; and VF in lateral and frontal projection and nasoendoscopy (all of the available assessment material). The cleft palate team of Göteborg, Sweden, mutually rated velopharyngeal function and recommended action based on the presented material. SUBJECTS: Nineteen consecutive patients (median age 7:5 years, range 4:4-19:7) investigated with VF in lateral and frontal projection and nasoendoscopy during 1997-99 at the cleft palate centre in Göteborg, Sweden. Post operative assessments were excluded. Percent agreement and Kappa calculations were used to compare the different combinations of parts of information to all of the available information. RESULTS: Thirteen of the 19 patients (68%) were recommended the same action regardless of the amount of presented information. Percent agreement (Kappa) between parts and all of the available information: VF in lateral projection 84% (0.75), VF in lateral and frontal projection 79% (0.74), and VF in lateral projection and nasoendoscopy 84% (0.72). CONCLUSIONS: VF in lateral projection is recommended to be the first step in visualising velopharyngeal function, and nasoendoscopy the next when further investigation is required.

- BACKGROUND AND AIMS: Longstanding uncertainty surrounds the selection of surgical protocols for the closure of unilateral cleft lip and palate, and randomised trials have only rarely been performed. This paper is an introduction to three randomised trials of primary surgery for children born with complete unilateral cleft lip and palate (UCLP). It presents the protocol developed for the trials in CONSORT format, and describes the management structure that was developed to achieve the long-term engagement and commitment required to complete the project.METHOD: Ten established national or regional cleft centres participated. Lip and soft palate closure at 3-4 months, and hard palate closure at 12 months served as a common method in each trial. Trial 1 compared this with hard palate closure at 36 months. Trial 2 compared it with lip closure at 3-4 months and hard and soft palate closure at 12 months. Trial 3 compared it with lip and hard palate closure at 3-4 months and soft palate closure at 12 months. The primary outcomes were speech and dentofacial development, with a series of perioperative and longer-term secondary outcomes.RESULTS: Recruitment of 448 infants took place over a 9-year period, with 99.8% subsequent retention at 5 years.CONCLUSION: The series of reports that follow this introductory paper include comparisons at age 5 of surgical outcomes, speech outcomes, measures of dentofacial development and appearance, and parental satisfaction. The outcomes recorded and the numbers analysed for each outcome and time point are described in the series.TRIAL REGISTRATION: ISRCTN29932826.

Gold mineralization in the Lappberget deposit, Garpenberg mine, Sweden: towards a geometallurgical approach

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This study investigates the mineralogy and texture of gold-bearing phases in the Lappberget deposit, Garpenberg Mine, and how these characteristics affect gold recovery during mineral processing. Multiple methods such as optical microscopy, SEM-EDS, EPMA, LA-ICP-MS, and bulk chemical analysis were applied on drill core samples, and samples from the processing plant’s Knelson gravity concentrator. Electrum-type alloys were recognized as the most common gold hosts.

Isolated cleft palate requires different surgical protocols depending on cleft type.

Tidskriftsartikel (refereegranskat)abstract
- A staged protocol for isolated cleft palate (CPO), comprising the early repair of the soft palate at 6 months and delayed repair of the eventual cleft in the hard palate until 4 years, designed to improve maxillary growth, was introduced. CPO is frequently associated with additional congenital conditions. The study evaluates this surgical protocol for clefts in the soft palate (CPS) and for clefts in the hard and soft palate (CPH), with or without additional malformation, regarding primary and secondary surgical interventions needed for cleft closure and for correction of velopharyngeal insufficiency until 10 years of age. Of 94 consecutive children with CPO, divided into four groups with (+) or without (-) additional malformations (CPS+or CPS-and CPH+or CPH-), hard palate repair was required in 53%, performed with small local flaps in 21% and with bilateral mucoperiosteal flaps in 32%. The total incidence of soft palate re-repair was 2% and the fistula repair of the hard palate was 5%. The total incidence of secondary velopharyngeal surgery was 17% until 10 years, varying from 0% for CPS-and 15% for CPH-, to 28% for CPS+and 30% for CPH+. The described staged protocol for repair of CPO is found to be safe in terms of perioperative surgical results, with comparatively low need for secondary interventions. Furthermore, the study indicates that the presence of a cleft in the hard palate and/or additional conditions have a negative impact on the development of the velopharyngeal function.

What may be learnt in ethics? Varieties of conceptions of ethical competence to be taught in compulsory school
- 2015

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the paper is to present the framework of this newly started project and report some initial findings. Questions about a compulsory school teaching ethics has regained urgency in Sweden since national tests are given in ethics. Every fourth child in grade six and nine are evaluated every year as having/not having approved knowledge of ethics, and one can ask if it is reasonable to be forced to undertake a test assessing your skills in ethics and risk being evaluated as not passing. This raises the question of what constitutes relevant knowledge in this field, a question which to a large extent has been absent in research. The purpose of the project is to identify and elucidate varieties of conceptions of ethical competence and critically analyse and discuss them, in relation to each other and in relation to ethical theory, as potential educational content in compulsory school.
