Epithelioid hemangioendothelioma (EH) is a rare neoplasm which can arise from any vascularised tissue and has the potential to metastasise. Correct diagnosis can be challenging as it has a variety of presentations and can mimic other pathology. We present a case arising from the brachial artery at the level of the antecubital fossa. Incision biopsies showed benign fatty tissue only; leading to delayed diagnosis, delayed excision and prolonged patient discomfort. This case shows the importance of exercising clinical judgement as negative incision biopsies were, with hindsight, not representative of the lesion. © 2012 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

To identify whether regular aspirin use protects against esophageal adenocarcinoma (EA) and if so, the effect of the duration and frequency of drug exposure. Methods: Studies were selected from five journal/trial databases based on defined inclusion and exclusion criteria; most notably, the provision of multivariate EA odds ratios (ORs) in those taking regular aspirin. A subgroup analysis was then performed by stratifying the results according to the frequency and duration of aspirin use. The reliability of these investigations was assessed by calculating study heterogeneity and observing any elements of publication bias. Results: Nine studies were selected for the main analysis, of which five were included in the frequency analysis and three assessed the duration of aspirin use. Data pooling revealed a statistically significant EA OR of 0.671 (95% CI 0.526-0.856, P=0.001) among all aspirin users, suggesting a protective effect. The results for duration and frequency did not reach statistical significance but nonetheless suggested possible benefits of longer, more frequent drug regimens that may be statistically confirmed by studies of larger sample sizes. Funnel plots and statistical tests demonstrated a minimal impact of publication bias on our results. Conclusion: Aspirin use confers a significant protective effect against EA with a suggestion that the degree of protection may be increased by the longer duration and higher frequency of usage. © 2013 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Objective: To determine health-related effects of viewing pro-eating disorder (Pro-ED) websites. Methods: A systematic review was carried out addressing: 1. The effect of viewing pro-ED websites on 'eating disorder behaviour', 2. The effect of viewing pro-ED websites on viewers' negative and positive affect. Results: Seven studies were included. Pro-ED viewers compared with controls showed higher levels of dieting and exercise (3 studies, 2 suggesting causation); higher levels of drive for thinness, body dissatisfaction and perfectionism (2 studies, both associative); a reduced likelihood of binging/purging (one study); increased negative affect (two studies); and a positive correlation between viewing pro-ED websites, disease duration and hospitalisations (one study). Conclusion: Viewing pro-ED websites may increase eating disorder behaviour but might not cause it. It may cause increased negative affect after a single short website exposure. For those with eating disorders, viewing is positively correlated with disease duration and hospitalisations. Professionals should be aware of these sites and their potential damage for health.

Docetaxel and vinorelbine have demonstrated efficacy in the treatment of metastatic breast cancer (MBC). This prospective feasibility study compared the efficacy of these two treatments in MBC. Patients with MBC progressing following anthracycline treatment were randomly assigned to either docetaxel (100 mg/m(2)day 1 q3W) or vinorelbine (25mg/m(2) day 1 q2W). Patients were eligible to cross over at progression. Objective response rates (ORR), time to progression (TTP) and overall survival (OS) were measured. 37 patients were randomised. 2 patients were excluded due to protocol violations. Of 35 remaining patients 17 received docetaxel and 18 received vinorelbine per protocol. ORR was 12.5% and 6.0% respectively for docetaxel and vinorelbine. The median time to progression was 10.4 weeks (range 6-14 weeks) in docetaxel arm and 7.6 weeks (range 4-11 weeks) in vinorelbine arm (p = .82). The clinical benefit rate (defined as complete response, partial response plus stable disease) was 44% in the docetaxel arm and 12% in the vinorelbine arm. Based on intent to treat the median OS in the docetaxel arm was 34 weeks (95% CI, 20.7-48) and 21.2 weeks (95% CI, 17-25.4) in vinorelbine arm (p = .388). 16 patients crossed over, 5 from docetaxel to vinorelbine and 11 from vinorelbine to docetaxel. At cross over the ORR was 0% and 18% on cross over to vinorelbine and docetaxel respectively with a median TTP of 17.3 weeks (95% CI, 16.3-18.1) and 18.7 weeks (95% CI, 13.9-23.4) for those receiving vinorebine and docetaxel at cross over respectively. Vinorelbine however was much better tolerated with fewer grade 3-4 toxicity events (n = 4) than docetaxel (n = 27). While docetaxel resulted in a longer TTP and OS in this study it did not reach statistical significance. TTP duration for those patients who crossed over was similar, but overwhelmingly vinorelbine had fewer significant grade 3-4 toxicities than docetaxel. Only two previous randomized studies have compared the efficacy of single agent docetaxel and vinorelbine following prior anthracycline exposure, one in an unselected population , and the other, HERNATA, in HER2 positive disease with trastuzumab used in both arms . The patients randomized in this study were relatively heavily pretreated with the majority having received 2-3 lines of prior treatment for their metastatic disease. The lower response rates with vinorelbine as compared to docetaxel in this study concur with results reported in other studies . However, the numbers in both this study and the other unselected study  are small and need to be interpreted with caution. With regard to toxicity, in the present study, grade 3-4 hematological adverse events and infection were tenfold greater with docetaxel as compared with vinorelbine, consistent with results in HERNATA . While others have reported a significantly higher number of overall grade 3-4 toxicities with vinorelbine , the fact that, as in HERNATA, discontinuations due to toxicities in that study  were significantly greater with docetaxel as compared to vinorelbine suggests either the toxicity data collected did not reflect the true toxicities on treatment or that docetaxel toxicities were in some way more severe or protracted leading to more numerous discontinuations . Larger randomized studies are needed to determine (1) the efficacy of docetaxel versus vinorelbine in anthracycline pretreated disease and (2) the efficacy of vinorelbine after prior taxane exposure, and particularly how it may compares both with regard to efficacy and tolerability with other possible regimens that may utilized such as carboplatin-gemcitabine  or eribulin . The longer as well as comparable TTP at cross over for both agents compared to that upfront suggests there may be enrichment at cross over of a group of patients who are not only fit for further treatment but are more likely to a derive continued benefit from additional treatment.

Ionising radiation is used extensively in trauma and orthopaedic perioperative practice for operative planning and intraoperative decision making. Radiation poses risks to patients and theatre staff, and it is important to always justify, optimise and limit the exposure. This is facilitated by a thorough understanding and awareness of radiation, as well as a sound knowledge of the precautions required for using this technology to minimise the risks of radiation.
