    Notes: Background  United States National Health Objectives include increasing the proportion of trips made by walking to and from school for children who live within 1.6 km to 50%. The purpose of this objective is to increase the level of physical activity among children. However, the impact of walking, bicycling or skating (active commuting) to and from school on the prevalence of overweight is unknown.Methods  Body mass index (BMI) was measured for 320 children (age 10.2 ± 0.7 years) in September. Over 5 months, an active commuting index (SI) and daily physical activity were estimated via questionnaire. In April, BMI and body fat were measured.Results  A significant positive association was found between April BMI and SI adjusting for September BMI (partial r = 0.03, P 〈 0.05). Positive associations were found between SI and physical activity before school (r = 0.17, P 〈 0.05) and daily moderate intensity physical activity (r = 0.13, P 〈 0.05). There were no significant association between SI and BF (P 〉 0.05).Conclusions  This preliminary data suggests that active commuting does not appear to provide sufficient amounts of physical activity to attenuate BMI; however, it may contribute to the attainment of physical activity recommendations. Future research is needed to objectively measure the impact of active commuting on the prevalence of overweight.

    Notes: Allergic contact dermatitis to prepackaged disposable alcohol prep swabs is infrequently reported. A 60-year-old woman developed repeated episodes of dermatitis at sites of injections and venipunctures. History and patch testing revealed contact allergy to Kendall Webcol alchol prep swabs. There were negative patch test results to isopropyl alcohol (IPA), but positive reactions to the Webcol swab, to the inner surface of the packaging foil, to two other brands of alcohol swabs, and to bacitracin. UV absorbance profile analysis revealed the presence of UV absorbing materials at peaks of 221 and 280 nm within commercial IPA samples, including one from Kendall, which were absent from reagent grade IPA. Reports of similar cases identified IPA, propylene oxide, or both as the allergens; when swab ingredients were negative, compound allergy was proposed. A recent report from Korea identified dodecyldiaminoethylglycine and IPA as the allergens in the commercial disinfectant swab. Although the exact allergen is undetermined in our case, it may represent a chemical compound or contaminant that is used or acquired during the manufacturing of the swabs or foils.

    Notes: Summary Charcoal haemoperfusion was performed for 5–12 h in three patients with maximal plasma phenobarbital concentrations of 600, 946 and 1044 µmol/l (138, 217 and 240 µg/ml). During haemoperfusion with constant blood flow phenobarbital elimination followed first order kinetics with half-lives of 11.1, 10.0 and 7.2 h, respectively. After termination of the haemoperfusion there was no rebound effect in plasma phenobarbital concentration and the elimination was first order with half-lives of 51, 82 and 48 h, respectively. Thus, the plasma phenobarbital half-life was reduced by 78–88% during haemoperfusion. In the same period 76–86% of the total body clearance of phenobarbital was due to the haemoperfusion column at a calculated volume of distribution of phenobarbital of 1.1–1.2 l/kg. This is clear evidence for recommending haemoperfusion in cases of serious poisoning with phenobarbital.
