This study involved a significantly larger number of patients than any previously reported, similar study. Possible reasons for differences in outcomes, and recommendations for best practice, are discussed.

Background Skin trauma may play a role in the development of morphea lesions. The association between trauma and the distribution of cutaneous lesions has never been examined. Objective Determine whether patients enrolled in the Morphea in Adults and Children (MAC) cohort exhibit skin lesions distributed in areas of prior (isotopic) or ongoing (isomorphic) trauma. Methods Cross-sectional analysis of the MAC cohort. Results Of 329 patients in the MAC cohort, 52 (16%) had trauma associated lesions at the onset of disease. Patients with lesions in an isotopic distribution had greater clinical severity as measured by a clinical outcome measure (mean modified Rodnan Skin Score of 13.8 vs. 5.3, P=0.004, 95% CI=3.08-13.92) and impact on life quality (mean Dermatology Life Quality Index 8.4 vs. 4.1, P=0.009, 95% CI 1.18-7.50) than those with an isomorphic distribution. Most frequent associated trauma were chronic friction (isomorphic) and surgery/isotopic. Limitations Recall bias for patient reported events. Conclusion Sixteen percent of patients in the MAC cohort developed initial morphea lesions at sites of skin trauma. If these findings can be confirmed in additional series, they suggest that elective procedures and excessive skin trauma or friction might be avoided in these patients.

A survey of 854 horse owners, trainers and equestrian managers in 10 regions of Great Britain and Ireland showed that 83 per cent provided their horses with routine prophylactic dental care at fixed intervals, including 49 per cent at intervals of 12 months and 30 per cent at intervals of six months; a further 10 per cent provided it only when they felt it was required and 7 per cent did not provide it at all. Overall, 44 per cent of the owners had their horse's wolf teeth (first premolar) extracted routinely; when prophylactic dentistry was provided, it was carried out solely by equine dental technicians (EDTS) for 53 per cent of owners, solely by veterinarians for 35 per cent, by both EDTS or veterinarians for 10 per cent of owners and by other than veterinarians or EDTS for 1 per cent. There was confusion among some horse owners concerning the qualifications of the EDTS, because no recognised British qualification was available until towards the end of this survey in 2001. Several reasons were cited by owners for choosing between veterinarians and EDTS including their perceived qualifications, personal recommendations, costs, the availability of a wide range of dental equipment and sedation, and the time and effort devoted to the procedures.

The levels of agreement for the final questionnaire show that the mandate for the consensus statements was exceptionally high. Implementation of the consensus is discussed, as are each of the key areas of the consensus, such as funding and minimum assessment standards.

BackgroundThe Vibrant Soundbridge middle ear implant and the Bonebridge bone conducting hearing device are hearing implants that use radio frequency transmission to send information from the sound processor to the internal transducer. This reduces the risk of skin problems and infection but requires a more involved surgical procedure than competitor skin penetrating devices. It is not known whether more complex surgery will lead to additional complications. There is little information available on the reliability of these systems and adverse medical or surgical events. The primary research question is to determine the reliability and complication rate for the Vibrant Soundbridge and Bonebridge. The secondary research question explores changes in quality of life following implantation of the devices. The tertiary research question looks at effectiveness via changes in auditory performance.MethodThe study was designed based on a combination of a literature search, two clinician focus groups and expert review.A multi-centre longitudinal observational study was designed. There are three study groups, two will have been implanted prior to the start of the study and one group, the prospective group, will be implanted after initiation of the study. Outcomes are surgical questionnaires, measures of quality of life, user satisfaction and speech perception tests in quiet and in noise.ConclusionThis is the first multi-centre study to look at these interventions and includes follow up over time to understand effectiveness, reliability, quality of life and complications.
