Femoroacetabular impingement: radiographic diagnosis--what the radiologist should know

OBJECTIVE: The purpose of this article is to show the important radiographic criteria that indicate the two types of femoroacetabular impingement: pincer and cam impingement. In addition, potential pitfalls in pelvic imaging concerning femoroacetabular impingement are shown. CONCLUSION: Femoroacetabular impingement is a major cause for early "primary" osteoarthritis of the hip. It can easily be recognized on conventional radiographs of the pelvis and the proximal femur.

[What you always wanted to know about HbA1c]

Irreversible, nonenzymatic glycation of the haemoglobin A beta chain leads to the formation of haemoglobin A1c (HbA1c), a stable minor haemoglobin component with enhanced electrophoretic mobility. The rate of formation of HbA1c is directly proportional to the ambient glucose concentration. HbA1c is commonly used to assess long-term blood glucose control in patients with diabetes mellitus, because the HbA1c value has been shown to predict the risk for the development of many of the chronic complications in diabetes. There are currently four principal glycohaemoglobin assay techniques (ion-exchange chromatography, electrophoresis, affinity chromatography and immunoassays) and over 20 methods that measure different glycated products. The ranges indicating good and poor glycaemic control can vary markedly between different assays. At the moment values differ between methodologies and even between different laboratories using the same methodology. Optimal use of HbA1c testing requires standardisation. There is progress towards international standardisation and improved precision of HbA1c which will lead to all assays reporting results in a standardised way. Clinicians ordering HbA1c testing for their patients should be aware of the type of assay method used, the reference interval, potential assay interferences (e.g. haemoglobinopathies, chronic alcohol ingestion, carbamylation products in uraemia) and assay performance. And they should know that a variety of factors have been shown to directly influence HbA1c values, e.g. iron deficiency anaemia, chronic renal failure and shortened red blood cell life span.

What a patient with refractory idiopathic detrusor overactivity should know about botulinum neurotoxin type a injection

PURPOSE: We documented the effects of intradetrusor injections of botulinum neurotoxin type A (Botox(R)) for refractory idiopathic detrusor overactivity so that prospective patients maybe properly informed about possible improvement in quality of life, the duration of interinjection intervals and the risk of clean intermittent self-catheterization. MATERIALS AND METHODS: A total of 81 consecutive patients with refractory idiopathic detrusor overactivity treated with intradetrusor injections of 200 U botulinum neurotoxin type A at 20 sites per injection course were evaluated in this prospective, nonrandomized, open label cohort study. The primary outcome was changes in quality of life, as assessed by the short form of the Urogenital Distress Inventory and the Incontinence Impact Questionnaire before and after treatment. Secondary outcomes were the interinjection interval and the need for clean intermittent self-catheterization. RESULTS: After intradetrusor botulinum neurotoxin type A injections there was significant improvement in quality of life, which was sustained after repeat injections. Mean Urogenital Distress Inventory and Incontinence Impact Questionnaire scores decreased from 56 to 26 and 59 to 21 after injection 1 in 81 patients, from 52 to 30 and 51 to 24 after injection 2 in 24, from 40 to 19 and 43 to 17 after injection 3 in 13, from 44 to 17 and 61 to 15 after injection 4 in 6 and from 51 to 17 and 63 to 14 after injection 5 in 4, respectively. The median interinjection interval was 15, 12, 14 and 13 months between injections 1 and 2, 2 and 3, 3 and 4, and 4 and 5, respectively. Considering a post-void residual urine of greater than 100 ml with lower urinary tract symptoms as the indication for clean intermittent self-catheterization, the overall clean intermittent self-catheterization rate after treatment was 43%. CONCLUSIONS: Intradetrusor botulinum neurotoxin type A injections for refractory idiopathic detrusor overactivity significantly improved quality of life. This effect was sustained after repeat injection. More than 2 of 5 patients with refractory idiopathic detrusor overactivity required clean intermittent self-catheterization after botulinum neurotoxin type A injections and all prospective patients should be informed about this.

Diverse Readings of the Court of Justice Judgments on Copyright Work

EU law’s impact on the meaning of the copyright work for a long time seemed limited to software and databases. But recent judgments of the CJEU (Infopaq, BSA, FootballAssociation [Murphy], Painer) suggest we have entered an era of harmonization of copyright subject-matter, after decades of focus on the scope of exclusive rights and their duration. Unlike before however, it is the Court and not the legislator that takes centre stage in shaping pivotal concepts. This article reviews the different readings and criticisms the recent case law on copyright works evokes in legal doctrine across the EU. It puts them in the wider perspective of the on-goingdevelopment towards uniform law and the role of the preliminary reference procedure in that process.
