A Sampler of International Media and Communication Statistics 2010
- 2011
-
Rapport (övrigt vetenskapligt)abstract
- The contemporary media culture raises more complex issues than ever before. Digital technologies, and advances of media such as the Internet, have driven the development. In this changing media landscape, traditional media, such as television, radio and newspapers, remain powerful, but their preconditions are affected. ‘A Sampler of International Media and Communication Statistics 2010’ is a collection and compilation of statistics from a large number of sources. The aim of the publication is to provide a comprehensive overview of international media and communication statistics, primarily concerning television and the Internet, but also, to a lesser extent, newspapers and radio. The emphasis of this publication is on the Internet and television. These two sections are divided into two parts, respectively ‘The world’ for comparisons between different parts of the world, and in ‘Regions’ for comparisons within different parts of the globe.

- OBJECTIVES: Assessment of health-related quality of life (HRQL) in head and neck cancer patients from diagnosis to 5 years after start of treatment. STUDY DESIGN: A prospective, descriptive study METHODS: three hundred fifty-seven patients from Norway and Sweden filled in HRQL questionnaires, the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 and the EORTC QLQ-H and N35, six times during the first year and then after 5 years. At 5 years, 167 (87%) of the 192 living patients filled in questionnaires. RESULTS: Group data: clinical significant improvements in HRQL were not found between 1 and 5 years. Problems with teeth, opening of the mouth, dryness in the mouth, and sticky saliva were persistent or worsening. Similar findings were found regardless of sex, age, stage, or site when clinical significant changes are considered. Patients who died between 1 and 5 years reported reduced HRQL on 15 of 28 scales at 1 year compared with the survivors. Individual data: 40% of patients reported improved global HRQL from diagnosis to 5 years after start of treatment. In addition, 11% had "top scores" at both assessment points. The pattern in global HRQL scores also applies for most of the other function and symptom scales. CONCLUSION: After the first year after treatment, recovery of the persisting side effects of treatment cannot be expected for the group as a whole. Patients must be prepared for this. Some individual patients experience improvement in global HRQL. HRQL assessments in daily clinical practice can identify patients who are in need of additional support and symptom relief.

- Abstract Objectives: To evaluate the space-maintaining capacity of a titanium mesh or a bioresorbable mesh after periosteal expansion and to assess bone formation under a titanium mesh or a bioresorbable mesh on the lateral border of the mandible by qualitative and quantitative histological analysis. Material and methods: In 13 rabbits, a self-inflatable soft tissue expander was placed intraorally, bilaterally under the mandibular periosteum via an extra oral approach. After 2 weeks, the expanders were removed and a particulated onlay bone graft was placed and covered by a titanium mesh or a bioresorbable mesh. After 3 months, the animals were sacrificed and specimens were collected for histology. Results: The osmotic soft tissue expander created a subperiosteal pocket and a ridge of new bone had formed at the edges of the expanded periosteum in all sites. After the healing period of 3 months, soft tissue dehiscence was recorded in two of the sites with bioresorbable meshes. The mean bone fill was 65% under the titanium mesh and 85% under the bioresorbable mesh (P<0.05). There was no significant difference between the titanium mesh and the bioresorbable mesh regarding the height of the meshes, mesh area and mineralized bone area. Scanning electron microscopy shows that new bone is growing in direct contact with the resorbable mesh and the titanium mesh. Conclusion: This study confirms that an osmotic soft tissue expander creates a surplus of periosteum and soft tissue and that new bone can be generated under a titanium mesh or bioresorbable mesh.

Alterations of temporomandibular disorders before and after orthognathic surgery
- 2007

Forskningsöversikt (övrigt vetenskapligt)abstract
- OBJECTIVE: To answer the question whether orthognathic surgery does affect the prevalence of signs and symptoms of temporomandibular disorders (TMDs). MATERIALS AND METHODS: A literature survey in the PubMed and Cochrane Library electronic databases was performed and covered the period from January 1966 to April 2006. The inclusion criteria were controlled, prospective or retrospective studies comparing TMDs before and after orthognathic surgery in patients with malocclusion. There were no language restrictions, and three reviewers selected and extracted the data independently. The quality of the retrieved articles was evaluated by four reviewers. RESULTS: The search strategy resulted in 467 articles, of which 3 met the inclusion criteria. Because of few studies with unambiguous results and heterogeneity in study design, the scientific evidence was insufficient to evaluate the effects that orthognathic surgery had on TMD. Moreover, the studies had problems with inadequate selection description, confounding factors, and lack of method error analysis. CONCLUSION: To obtain reliable scientific evidence, additional well-controlled and well-designed studies are needed to determine how and if orthognathic surgery alters signs and symptoms of TMD.

TMD before and after correction of dentofacial deformities by orthodontic and orthognathic treatment

Tidskriftsartikel (refereegranskat)abstract
- Abstract The aims of the study were to investigate the alteration of temporomandibular disorders (TMD) after correction of dentofacial deformities by orthodontic treatment in conjunction with orthognathic surgery; and to compare the frequency of TMD in patients with dentofacial deformities with an age and gender matched control group. TMD were evaluated in 121 consecutive patients (treatment group), referred for orthognathic surgery, by a questionnaire and a clinical examination. 18 months after treatment, 81% of the patients completed a follow-up examination. The control group comprised 56 age and gender matched subjects, of whom 68% presented for follow-up examination. TMD were diagnosed according to research diagnostic criteria for TMD. At baseline examination, the treatment group had a higher frequency of myofascial pain (P=.035) and arthralgia (P=.040) than the control group. At follow-up, the frequencies of myofascial pain, arthralgia and disc displacement had decreased in the treatment group (P=.050, P=.004, P=.041, respectively). The frequency of TMD was comparable in the two groups at follow-up. Patients with dentofacial deformities, corrected by orthodontic treatment in conjunction with orthognathic surgery, seem to have a positive treatment outcome in respect of TMD pain

TMD in consecutive patients referred for orthognathic surgery
- 2009

Ingår i: Angle Orthodontist;4. - 0003-3219. ; 79:4, s. 621-7
-
Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To answer the question whether temporomandibular disorders (TMD) were more common in a group of individuals referred for orthognathic surgery than in a control group. The null hypothesis was that neither the frequency of signs and symptoms of TMD or diagnosed TMD would differ between the patient group and a control group. MATERIALS AND METHODS: A sample of 121 consecutive patients referred for orthognathic surgery at the Department of Oral Maxillofacial Surgery, Malmö University Hospital, Sweden, was interviewed and examined regarding signs and symptoms of TMD and headaches. A control group was formed by 56 age- and gender-matched individuals attending the Department of Oral Diagnosis, Faculty of Odontology, Malmö University, Sweden, and Public Dental Health Clinic in Oxie, County of Skane, Sweden. TMD diagnoses were used according to Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). RESULTS: The patient group showed more myofascial pain without limited opening, disc displacement with reduction, and arthralgia according to RDC/TMD than the control group. The patient group also had more symptoms and signs of TMD in general. CONCLUSIONS: The null hypothesis was rejected because patients who were to be treated with orthognathic surgery had more signs and symptoms of TMD and higher frequency of diagnosed TMD compared with the matched control group.
