Aim: To get insight into the frequency of venous leg ulceration in the Dutch dermatologic practice, and into how this profession treats this disease. Design: Material and Methods: An e-survey was conducted. To all Dutch dermatologists and residents dermatology an email was sent with an online link to a questionnaire on venous leg ulcers. Results: The overall response was 30 %. 83.5 % of the doctors usually treat their patients according to the guideline. The dermatologic practice consists on average of 73 patients (range 0-500; SD 93) with leg ulceration, and yearly 54 new leg ulcer patients (range 0-300; SD 50) are seen. 65 % of the patients are women, 80 % is more than 45 years of age and 55 % is older than 65. Of all ulcers, 77 % has a venous aetiology, of which 59 % has a primary cause. Mean time to heal is 74 days (range 4-200; SD 39). Per year, dermatologists admit on average 7 patients (range 0-50; SD 11) because of leg ulceration. Eventually, 47 % of the admitted patients are treated by skin transplantation. Conclusions: This questionnaire gives a good insight in the epidemiology, and the diagnostic and therapeutic regimen for patients with venous leg ulcers in Dutch dermatologic practice. © Schattauer 2013.

Safe and reliable traffic management is vital for uninterrupted and successful operation of the European rail network, where mixed traffic (i.e. freight and passenger) services are run. Although rail freight derailment is infrequent, its consequences can be severe and may result in different forms of costs, including infrastructure; rolling stock; traffic disruptions; injuries and fatalities. The objective of this research paper is to conduct a cost benefit analysis (CBA) to identify cost effective mitigation techniques for efficient rail freight traffic management in Europe, by 2050. Reviewing previous derailments and studies, eight sets of derailment causes are analysed and, for each of them, sets of mitigation techniques are aimed at for their alleviation. The study finds that the highest cumulative costs of derailment are associated with 'wheel failure', while the lowest cumulative cost is identified for 'excessive track width'. Regarding mitigation techniques, the lowest cumulative benefits are demonstrated for 'track height' interventions, whereas 'wheel failure' alleviation demonstrates the highest benefits, in value terms (all by 2050). In most cases, the benefit to cost ratio did not exceed 2.6; in two cases ('track height' and 'rail failures') the ratio remained below 1 - a negative outcome where cost is higher than benefit. The study suggests that the most cost-efficient interventions are those applied to 'hot axle box and axle rupture' and 'spring and suspension failure'. © 2015 Elsevier Ltd. Source
