Background: Urinary mercury concentrations are used in research exploring mercury exposure. Some theorists have proposed that autism is caused by mercury toxicity. We set out to test whether mercury concentrations in the urine of children with autism were significantly increased or decreased compared to controls or siblings. Methods: Blinded cohort analyses were carried out on the urine of 56 children with autism spectrum disorders (ASD) compared to their siblings (n = 42) and a control sample of children without ASD in mainstream (n = 121) and special schools (n = 34). Results: There were no statistically significant differences in creatinine levels, in uncorrected urinary mercury levels or in levels of mercury corrected for creatinine, whether or not the analysis is controlled for age, gender and amalgam fillings. Conclusions: This study lends no support for the hypothesis of differences in urinary mercury excretion in children with autism compared to other groups. Some of the results, however, do suggest further research in the area may be warranted to replicate this in a larger group and with clear measurement of potential confounding factors. © 2012 Wright et al.

Patients with advanced chronic heart failure (CHF) can experience 'revolving door' admissions, often for parenteral diuretics, when time at home is precious. Home intravenous diuretic services are patchy. This retrospective review describes 43 consecutive episodes of continuous subcutaneous infusion of furosemide (CSCI-F) in 32 advanced CHF patients; 28 episodes aiming to correct fluid balance and prevent hospital admission and 15 aiming to prevent symptoms in the dying.Overall, 26/28 (93%) avoided hospital admission. Weight loss occurred in 20/28 (70%): a median loss of 5.6 kg [interquartile range (IQR) 0.1-8.9]). The daily dose of furosemide ranged from 40 to 250 mg. The median number of days on CSCI-F was 10.5 (range 2-48; IQR 6-13.8). Site reactions occurred in 10/43 (23%); all of which were mild except two, one of which required oral antibiotics. Symptoms were controlled in all 15 dying patients.CSCI-F for patients with advanced CHF is effective in terms of weight loss and prevention of hospital admission with the heart failure nurse specialist playing a key overall management role in selection and monitoring. As the majority of community and hospice nurses have access to and are familiar with CSCI pumps, this practice should be nationally transferable. The role in the dying patient requires further assessment. © The Author(s) 2011 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
