Automated microscopy is increasingly used to screen for suspected urinary tract infection and it has a 98.8% negative predictive value in adults. But does it work as well in a purely paediatric practice? Automated microscopy did as well as dipstick testing to rule out urinary tract infection in children, and it offered improved specificity and slightly reduced sensitivity. The process is cost cutting, since it can be performed out-of-hours in a similar way to biochemical and haematology sample processing (Archives of Disease in Childhood 2010;95:193-7, doi:10.1136/adc.2009.166835).

Vitamin D deficiency is easy to tackle and, in patients undergoing hip replacement for osteoarthritis, appears to be a risk factor for suboptimal outcome. A study found that the vitamin D deficient group had lower preoperative Harris hip scores and were less likely to walk away with an excellent outcome after hip replacement than the vitamin D sufficient group, being otherwise matched for age, sex, and anaesthetic risk (Journal of Bone and Joint Surgery 2010;92-B:362-6, doi:10.1302/0301-620X.92B3.23535). Vitamin D levels positively correlated with preoperative and postoperative hip scores. …
