Abstract
BACKGROUND Initial management of children diagnosed with type 1 diabetes (T1D) varies worldwide with sparse high quality evidence regarding the impact of different models of care. AIM To compare the inpatient model of care with a hybrid home-based alternative, examining metabolic and psychosocial outcomes, diabetes knowledge, length of stay, and patient satisfaction. SUBJECTS AND METHODS The study design was a randomized-controlled trial. Inclusion criteria were: newly diagnosed T1D, aged 3 to 16 years, living within approximately 1 hour of the hospital, English-speaking, access to transport, absence of significant medical or psychosocial comorbidity. Patients were randomized to standard care with a 5 to 6 day initial inpatient stay or discharge after 2 days for home-based management. All patients received practical skills training in the first 48 hours. The intervention group was visited twice/day by a nurse for 2 days to assist with injections, then a multi-disciplinary team made 3 home visits over 2 weeks to complete education. Patients were followed up for 12 months. Clinical outcomes included HbA1c, hypoglycemia, and diabetes-related readmissions. Surveys measured patient satisfaction, diabetes knowledge, family impact, and quality of life. RESULTS Fifty patients were recruited, 25 to each group. There were no differences in medical or psychosocial outcomes or diabetes knowledge. Average length of admission was 1.9 days shorter for the intervention group. Families indicated that with hindsight, most would choose home- over hospital-based management. CONCLUSIONS With adequate support, children newly diagnosed with T1D can be safely managed at home following practical skills training.

Abstract
A prospective randomised controlled pilot study was performed comparing home oxygen therapy with traditional inpatient hospitalisation for children with acute bronchiolitis. Children aged 3-24 months with acute bronchiolitis, still requiring oxygen supplementation 24 h after admission to hospital, were randomly assigned to receive oxygen supplementation at home with support from "hospital in the home" (HiTH) or to continue oxygen supplementation in hospital. 44 children (26 male, mean age 9.2 months) were recruited (HiTH n = 22) between 1 August and 30 November 2007. Only one child from each group was readmitted to hospital and there were no serious complications. Children in the HiTH group spent almost 2 days less in a hospital bed than those managed as traditional inpatients: HiTH 55.2 h (interquartile range (IQR) 40.3-88.9) versus in hospital 96.9 h (IQR 71.2-147.2) p = 0.001. Home oxygen therapy appears to be a feasible alternative to traditional hospital oxygen therapy in selected children with acute bronchiolitis.

Abstract
OBJECTIVE To measure changes in spinal and femoral neck bone mineral densities in patients treated for Graves thyrotoxicosis. DESIGN Cohort study. SETTING Tertiary care center. PATIENTS Fifteen women with active Graves thyrotoxicosis. Six patients were premenopausal and nine were postmenopausal. All patients had evidence of thyrotoxicosis as indicated by a raised total serum thyroxine, suppressed serum thyroid-stimulating hormone, and an elevated technetium-99m pertechnetate thyroid scan. A control group of 15 healthy volunteers matched for age, sex, and menopausal status were followed during the same period. MEASUREMENTS Bone mineral density was measured by dual-energy x-ray absorptiometry at baseline and after 12 months of antithyroid therapy when euthyroidism had been achieved. RESULTS After 12 months of therapy, total serum thyroxine, total serum triiodothyronine, serum alkaline phosphatase, and serum bone Gla-protein activities had returned to normal in all patients (P < 0.001 for all comparison between initial and final biochemical measurements). During this interval, the mean lumbar spine bone mineral increased from an initial value of 1.01 g/cm2 to 1.07 g/cm2, an increase of 6.6% per year (95% CI, 3.6% to 9.6%) (P < 0.001 compared with controls). Increases in femoral neck (1.2%/y; CI, -2.1% to 4.5%; P = 0.2 compared with controls) and femoral trochanter bone mineral (3.2%/y; CI, 2.4% to 8.7%; P = 0.2 compared with controls) were not statistically significant. Using forced-entry multiple regression analysis, the severity of the thyrotoxicosis was independently associated with the percentage increment in lumbar spine bone mineral density after 12 months of antithyroid therapy. CONCLUSION Effective treatment of Graves thyrotoxicosis was associated with increases in lumbar spine and femoral neck bone mineral. Although the changes in bone mineral were modest, our data suggest that thyrotoxic bone loss may be a reversible disorder.

Abstract
Three contaminants were identified during drug screening of postmortem blood samples which had been stored in glass bottles with a black rubber seal. Two of these contaminants, cyanoethyl dimethyldithiocarbamate and N-phenyl-2-naphthylamine, were found to come from the rubber seal of some bottles. The third contaminant was not a single compound but rather a mixture of aryl phosphates with a composition very similar to technical grade tritolyl phosphate. The origin of these phosphates is at present unknown.

Abstract
A simple and efficient method, based on the adsorption properties of octadecasilane bonded silica, is described for the rapid extraction of acidic drugs from whole post mortem blood. The blood was diluted, passed through an extraction column containing the bonded silica and the absorbed drugs were eluted with methanol. Following extraction into diethylether, the drugs were methylated and chromatographed. Recoveries were generally in excess of 80% at the microgram/mL level and the method substantially reduced the quantity of co-extracted lipids normally found in the acid extracts of hemolyzed blood. The procedure proved suitable for up to 2 mL blood and yielded clean extracts for gas chromatographic analysis.

Abstract
Abscisic acid (ABA) in extracts of somatic embryos and seeds of Gloryvine (Vitis vinifera L.xV. rupestris Scheele) was measured by gas chromatography-mass spectrometry-selected ion monitoring using deuterated ABA, (±)-[C-3Me-(2)H3]ABA, ([(2)H3]ABA) as internal standard. The ABA content increased rapidly during embryogeny (0.035 ng/embryo at the globular stage to 0.22 ng/embryo at the mature stage). The level of ABA in the tissues of somatic embryos, expressed in ng/mg dry weight, decreased from the globular stage (0.76 ng/mg) to the mature stage (0.25 ng/mg). Chilling (4° C) induced normal germination of seeds and mature somatic embryos and precocious germination of globular, heart-shaped and torpedoshaped somatic embryos. In all cases chilling led to a marked reduction in endogenous ABA. Exogenous (±)-ABA inhibited the germination of chilled somatic embryos.

Abstract
A contaminant was found to leach into the contents of two brands of disposable syringes. It was identified as 2-(2-hydroxyethylmercapto) benzothiazole and is believed to be formed during manufacture of the syringes as a result of a reaction between 2-mercaptobenzothiazole, a rubber vulcanization accelerator, and ethylene oxide, used for sterilization. The contaminant was isolated form the rubber plunger-seal and identified using mass, NMR, and UV spectroscopic methods. The amount of contaminant appearing in the contents of syringes was measured; up to 140 micro g was found under clinically relevant conditions. This finding has important implications with respect to the use of these syringes for drug administration and for the collection of blood for drug analyses.

Abstract
Methods for the quantitation of doxapram in blood, plasma and urine have been developed. Following extraction, gas-liquid chromatography was used to separate doxapram from basic metabolites. Doxapram was detected by mass spectrometry for blood and plasma assays, and by flame ionisation for urine assays. The limit of reliable quantitation in blood and plasma was 10 ng and in urine 500 ng, the coefficients of variation being 6.37%, 1.72% and 2.31% respectively. To illustrate the clinical applicability of the assay methods, plasma, blood and urine levels were monitored in a premature newborn following an intravenous infusion of doxapram.

Abstract
The potential of chemical ionization mass spectrometry for the characterization of naturally occurring and semi-synthetic cardiac glycosides has been investigated. Methane, isobutane and ammonia were used as reactant gases. With the exception of ouabain, the ammonia chemical ionization mass spectra of the cardiac glycosides examined in this work contained abundant [M + NH4]+ions and abundant fragment ions formed by cleavage of glycoside bonds. Ammonia chemical ionization mass spectrometry was found to provide a rapid and sensitive method for the characterization of the products of glycosidation reactions. In contrast, the methane and isobutane chemical ionization mass spectra of the cardiac glycosides, with the exception of ouabain, did not contain protonated molecular ions and did not contain abundant fragment ions above m/z 400.

Abstract
With conventional transmissive photocathodes, an appreciable amount of the incident light passes through the photocathode layer without contributing to the electron emission. It is possible, at certain predetermined wavelengths, to reduce these light losses and thereby to increase the quantum efficiency of the cathode by making it part of a reflection interference filter. In practice, this involves the deposition of the photocathode on a dielectric which is, in turn, deposited on an opaque mirror. The thin-film optics of the above arrangement has been considered theoretically, and the possible increase in light absorption, and hence in electron emission, could be predicted. Evaluation of actual tri-alkali (S-20) photocathodes constructed along the above lines agree with, and at times even exceed, the theoretical enhancement factor of about three to five, thus establishing the practicability of the method considered.
