Background/aims To study the effectiveness and clinical relevance of eyes treated with good (better than 6/12 or >70 Early Treatment Diabetic Retinopathy Study letters) visual acuity (VA) when initiating treatment with ranibizumab for neovascular age-related macular degeneration (nAMD) in the UK National Health Service. Currently eyes with VA better than (>) 6/12 are not routinely funded for therapy. Methods Multicentre national nAMD database study on patients treated 3-5 years prior to the analysis. Anonymised structured data were collected from 14 centres. The primary outcome was the mean VA at year 1, 2 and 3. Secondary measures included the number of clinic visits and injections. Results The study included 12 951 treatment-naive eyes of 11 135 patients receiving 92 976 ranibizumab treatment episodes. A total of 754 patients had baseline VA better than 6/12 and at least 1-year of follow up. Mean VA of first treated eyes with baseline VA>6/12 at year 1, 2, 3 were 6/10, 6/12, 6/15, respectively and those with baseline VA 6/12 to >6/24 were 6/15, 6/17, 6/20, respectively (p values <0.001 for comparing differences between 6/12 and 6/12-6/24 groups). For the second eyes with baseline VA>6/12, mean VA at year 1, 2, 3 were 6/9, 6/9, 6/10 and those with baseline VA 6/12 to >6/24 were 6/15, 6/15, 6/27, respectively (p values <0.001-0.005). There was no significant difference in the average number of clinic visits or injections between those with VA better and worse than 6/12. Conclusions All eyes with baseline VA>6/12 maintained better mean VA than the eyes with baseline VA 6/12 to >6/24 at all time points for at least 2 years. The significantly better visual outcome in patients who were treated with good baseline VA has implications on future policy regarding the treatment criteria for nAMD patients' funding. Source

Introduction: Anorexia nervosa is a mental health disorder characterised by deliberate weight loss (through restrictive eating, excessive exercise and/or purging), disordered body image, and intrusive overvalued fears of gaining weight. The National Institute for Clinical Excellence recommends that family interventions that directly address the eating disorder should be offered to children and adolescents with anorexia nervosa. Aims: To perform a literature review to assess whether family therapy is a more effective intervention than other treatments in the management of adolescents with anorexia nervosa. Method: Search of PubMed, The Cochrane Library and NHS Evidence for randomised controlled trials that compared a family intervention with another treatment for anorexia nervosa in adolescence. Results and discussion: This literature search revealed only six randomised controlled trials investigating the use of family therapy in the treatment of adolescents with anorexia nervosa, and these all had small sample sizes. Some, but not all, of these trials suggest that family therapy may be advantageous over individual psychotherapy in terms of physical improvement (weight gain and resumption of menstruation) and reduction of cognitive distortions, particularly in younger patients. Due to the small sample sizes and the significant risk of bias (particularly information bias) in some of the studies the evidence in favour of family therapy over individual therapy is weak. In the future, larger randomised controlled trials with long term follow-up are required to assess whether family therapy is the most effective treatment for anorexia nervosa in adolescence. © Medicinska naklada.

Objectives: We have developed a new grading system for hip osteoarthritis using clinical computed tomography (CT). This technique was compared with Kellgren and Lawrence (K&L) grading and minimum joint space width (JSW) measurement in digitally reconstructed radiographs (DRRs) from the same CT data. In this paper we evaluate and compare the accuracy and reliability of these measures in the assessment of radiological disease. Design: CT imaging of hips from 30 female volunteers aged 66±17 years were used in two reproducibility studies, one testing the reliability of the new system, the other testing K&L grading and minimum JSW measurement in DRRs. Results: Intra- and inter-observer reliability was substantial for CT grading according to weighted kappa (0.74 and 0.75 respectively), while intra- and inter-observer reliability was at worst moderate (0.57) and substantial (0.63) respectively for DRR K&L grading. Bland-Altman analysis showed a systematic difference in minimum JSW measurement of 0.82mm between reviewers, with a least detectable difference of 1.06mm. The area under the curve from ROC analysis was 0.91 for our CT composite score. Conclusions: CT grading of hip osteoarthritis (categorised as none, developing and established) has substantial reliability. Sensitivity was increased when CT features of osteoarthritis were assigned a composite score (0=none to 7=severest) that also performed well as a diagnostic test, but at the cost of reliability. Having established feasibility and reliability for this new CT system, sensitivity testing and validation against clinical measures of hip osteoarthritis will now be performed. © 2014 Osteoarthritis Research Society International.

Objective: To explore undergraduate medical students' attitudes towards and opinions about leadership and management education. Design: Between 2009 and 2012 we conducted a qualitative study comprising five focus group discussions, each devoted to one of the five domains in the Medical Leadership Competency Framework, (Personal Qualities, Working with Others, Managing Services, Improving Services and Setting Direction). Each discussion examined what should be learnt, when should learning occur, what methods should be used, how should learning be assessed, what are the barriers to such education. Participants: 28 students from all three clinical years (4-6) of whom 10 were women. Results: 2 inter-related themes emerged: understanding the broad perspective of patients and other stakeholders involved in healthcare provision and the need to make leadership and management education relevant in the clinical context. Topics suggested by students included structure of the National Health Service (NHS), team working skills, decision-making and negotiating skills. Patient safety was seen as particularly important. Students preferred experiential learning, with placements seen as providing teaching opportunities. Structured observation, reflection, critical appraisal and analysis of mistakes at all levels were mentioned as existing opportunities for integrating leadership and management education. Students' views about assessment and timing of such education were mixed. Student feedback figured prominently as a method of delivery and a means of assessment, while attitudes of medical professionals, students and of society in general were seen as barriers. Conclusions: Medical students may be more open to leadership and management education than thought hitherto. These findings offer insights into how students view possible developments in leadership and management education and stress the importance of developing broad perspectives and clinical relevance in this context.

Introduction. Aggregatibacter paraphrophilus (former name Haemophilus paraphrophilus) is a normal commensal of the oral flora. It is a rare cause of hepatobiliary or intracerebral abscesses. Case presentation. We report a case of a 53-year-old Caucasian man with a liver abscess and subsequent brain abscesses caused by Aggregatibacter paraphrophilus. The probable source of the infection was the oral flora of our patient following ingestion of a dental filling. The presence of a large patent foramen ovale was a predisposing factor for multifocal abscesses. Conclusion. In this case report, we describe an unusual case of a patient with both liver and brain abscesses caused by an oral commensal Aggregatibacter paraphrophilus that can occasionally show significant pathogenic potential. © 2010 Ariyaratnam et al; licensee BioMed Central Ltd.
