Abstract
Introduction: neurologically impaired children frequently experience nutritional disorders and bone health complications. Our aim was firstly to analyze a method to interpret bone mineral density (BMD) accurately in neurologically impaired children. Secondly, to determine its relationship with the nutritional status and micronutrient levels in order to identify which factors are associated with low BMD. Methods: a observational multicenter study was conducted in children with moderate-to-severe neurological impairment. Data collected included: medical records, anthropometric measures, hematologic and biochemical evaluation. BMD was measured with Dual-energy X-ray absorptiometry and z-scores were calculated adjusting for sex and chronological age. Secondly, BMD z-scores were calculated applying height age (age at which the child's height would be in 2nd percentile) instead of chronological age. Results: fifty-two children were included (aged 4-16 years). Seventeen patients (32.7%) received feeding by gastrostomy tube. Height and BMI z-score were below 2SD in 64% and 31% of patients respectively, with normal mid upper arm circumference and skinfold thickness measurements. Low vitamin-D levels were found in 42% of cases. 50% of patients evidenced low BMD when calculated for chronological age, whereas only 34.5% showed BMD z-score <-2 when calculated for height age. No correlation was observed between BMD and vitamin-D levels, weight and height z-scores or age when BMD was calculated applying height age. Conclusions: the prevalence of low BMD is high in neurologically impaired children, and it is probably multifactorial. In these children, we suggest adjusting BMD for height age, in order not to over diagnose low BMD.

Abstract
BACKGROUND There is a well-established relation of symptom severity with functional status and mortality after an index stroke. However, little is known about the impact of symptom severity of a recent index stroke on risk of recurrent vascular events. METHODS We reviewed the data set of a multicenter trial involving 3680 recent noncardioembolic stroke patients aged 35 years or older and followed for 2 years. Independent associations of stroke severity (as measured by National Institutes of Health Stroke Scale [NIHSS] score) with recurrent stroke (primary outcome) and stroke/coronary heart disease (CHD)/vascular death (secondary outcome) were analyzed. NIHSS score was analyzed as a dichotomous (<4 versus ≥4) and a continuous variable. RESULTS Among study subjects, 550 (15%) had NIHSS scores of 4 or more (overall scores ranged from 0 to 18, median score was 1 [25th-75th percentile 0-2]). NIHSS was measured at a median of 35 days after the index stroke. After adjusting for multiple covariates, NIHSS of 4 or more was independently linked to a higher risk of recurrent stroke (hazard ratio [HR], 1.37; 95% confidence interval [CI], 1.01-1.84) and risk of stroke/CHD/vascular death (HR, 1.32; 95% CI, 1.07-1.64). Analysis of NIHSS score as a continuous variable also showed a higher risk of recurrent stroke (HR, 1.06; 95% CI, 1.00-1.12) and stroke/CHD/vascular death (HR, 1.05; 95% CI, 1.01-1.09) with increasing index stroke symptom severity. CONCLUSIONS Greater residual symptom severity after a recent stroke is associated with higher risk of recurrent vascular events. Future studies are needed to confirm this relationship and to clarify its underlying mechanisms.

Abstract
BACKGROUND Drooling saliva is a common problem in children with neurodevelopmental disorders. The negative consequences of drooling include skin breakdown, dehydration, and damage to clothing and equipment. Children and families often suffer social embarrassment due to drooling. There is no evidence about the relative effectiveness, side effect profiles or patient acceptability of the two medications most commonly used to reduce drooling - glycopyrronium and hyoscine. Consequently, there is no consensus or guideline to aid clinical decisions about which drug to use, and at what dose. METHODS/DESIGN A multi-centre, randomised trial of treatment with glycopyrronium or hyoscine in children with problematic drooling and non-progressive neurodisability. Ninety children aged between 3 and 15 years who have never received medication for drooling will be stratified by severity of drooling and care centre. Randomisation to receive treatment with glycopyrronium or hyoscine will be computer generated from the trial randomisation website. Dose adjustment and side effect monitoring will occur via telephone consultation. Medication arm will be known to participants and clinicians but not the Trial Outcome Assessor.The primary outcome measure is the Drooling Impact Scale score at four weeks, at which time all children will be on the maximum tolerated dose of their medication. Secondary outcome measures include change in Drooling Impact Scale score between baseline, 4, 12 and 52 weeks, change in Drooling Severity and Frequency Scale score and difference between groups in the Treatment Satisfaction Questionnaire for Medication score. A structured interview with children and young people of sufficient age, cognitive and communication ability will explore their perceptions of drooling and the effectiveness and acceptability of the medications. DISCUSSION The primary objective of the study is to identify whether glycopyrronium or hyoscine is more effective in treating drooling in children with non-progressive neurodisability. The study will also determine which medications at what doses are most acceptable and have fewest side effects. This information will be used to develop evidence based guidance to inform the medical treatment of drooling.
