Abstract
A young man was admitted for a polytraumatism associating head trauma and blunt abdominal trauma with hepatic injury. He was managed with a damage control surgery with a perihepatic packing. During the second look surgery, he developed a paradoxal gazous embolism by air aspiration in the sus-hepatic vein. This has never been described before in such traumatism. The patient presented a respiratory distress, a circulatory shock due to right infarction and an intracranial hypertension with bilateral mydriasis. He was immediately treated by hyperbaric oxygenotherapy. The evolution was good and he recovered without sequelae.

Abstract
We study fully developed, steady granular flows confined between parallel flat frictional sidewalls using numerical simulations and experiments. Above a critical rate, sidewall friction stabilizes the underlying heap at an inclination larger than the angle of repose. The shear rate is constant and independent of inclination over much of the flowing layer. In the direction normal to the free surface, the solid volume fraction increases on a scale equal to half the flowing layer depth. Beneath a critical depth at which internal friction is invariant, grains exhibit creeping and intermittent cage motion similar to that in glasses, causing gradual weakening of friction at the walls.

Abstract
Policy guidance suggests that outcomes for adolescents with mental health problems can be improved by secondary education services (SES) and child and adolescent mental health services (CAMHS) working more closely. This study reports on staff experiences of the introduction of a mental health link worker (MHLW). The findings of two focus groups are presented, conducted with staff from CAMHS and SES. These focus groups formed part of the overall wider evaluation of the MHLW role. The groups explored staff perceptions and experiences following the introduction of the MHLW, and elicited their views on the effectiveness of this innovative role. Qualitative methods were employed, and analysis was conducted using the principles of grounded theory and the constant comparative method. The findings revealed that the MHLW was well received by both groups, despite the identification of potential barriers. A number of key themes emerged, which included the ability of the link worker to improve communication and to encourage mutual understanding between services. The issues raised by these themes are discussed and recommendations are made for future practice and research.

Abstract
Asthma and other respiratory diseases have increased in the last years among Venezuelan children from helminthic endemic areas where the infection by Ascaris lumbricoides has been associated to bronchial airway inflammation in parasitized individuals. The aim of this work was to investigate the possible associations between the development of bronchial hyper reactivity and the immune response against A. lumbricoides in urban and rural children. We evaluated 470 school children from rural and urban communities. Pulmonary function tests were performed and >or=20% PC(20) changes were considered as a positive diagnostic of bronchial hyper reactivity. The prevalence and intensity of A. lumbricoides infection was determined by faecal examination. Specific serum IgE levels using a modified ELISA and skin prick tests against A. lumbricoides and the common allergen Dermatophagoides pteronyssinus were done. The number of circulating lymphocyte sub populations was determined by flow cytometry analysis. In rural children, bronchial hyper reactivity was associated with increased specific levels of anti-A. lumbricoides IgE (p<0.0001) and skin test positivity for A. lumbricoides (p<0.0001). The percentage of FEV1 predictive values correlated inversely (p<0.0001) with anti-A. lumbricoides IgE levels. Elevated numbers of circulating CD3+CD4+ and CD20+CD23+ cells were found in rural children with bronchial hyper reactivity compared to their asymptomatic counterparts. They correlated positively with anti-A. lumbricoides IgE levels (p<0.005 and <0.0001, respectively). In contrast, in urban children, bronchial hyper reactivity was associated with elevated anti-D. pteronyssinus IgE levels (p=0. 0089), skin hyper reactivity towards this aero allergen (p=0.003) and to an increase in the number of CD3+CD8+ (p<0.0001). Our results suggest that the IgE response against A. lumbricoides infection may be involved in the development of bronchial hyper reactivity among rural children from endemic areas and also that improved hygienic conditions in the urban environment is associated with increased responses to airborne allergens.

Abstract
AIM Metrological survey of analytic equipment is developing well in French blood bank laboratories, but still the limits of critical parameters affecting the result of basic methods are usually not defined. The aim of this study is to establish experimentally maximum permissible errors for critical physical values involved in microplate ABO-RH1 blood grouping, such as temperature and time of incubation and volumes of reagents and blood samples. MATERIALS AND METHODS Samples were internal quality controls used routinely in the laboratory. Three set points were defined for each parameter: incubation temperature 18, 22 and 26 degrees C; incubation time 10, 15 and 20 min; reagent sera and sample cells volume 20, 30 and 40 microL; reagent cells volume 15, 20 et 25 microL; plasma sample volume 30, 40 et 50 microL. All equipments (temperature test chamber, chronometer and pipettors) were calibrated using national standards (COFRAC) according to appropriate methods for estimation of uncertainty of measurement. Significant components of uncertainty were taken into account to define a global uncertainty for each measurable quantity. RESULTS All tests results from any combination of the above set points (n=81 for each sample tested in triplicate) were consistent with the expected result. Not one undetermined result was observed. CONCLUSION The experimental design of this study allowed us to define accurately maximum permissible errors for major critical parameters involved in microplate ABO-RH1 blood grouping. Hence these values must be applied to metrological survey of the equipment. Further, our study demonstrates the robustness of the method.

Abstract
Alagille syndrome (AGS) is caused by heterozygous mutations in JAG1, and mutations have been previously reported in about 70% of patients who meet clinical diagnostic criteria. We studied a cohort of 247 clinically well-defined patients, and using an aggressive and sequential screening approach we identified JAG1 mutations in 94% of individuals. Mutations were found in 232 out of 247 patients studied and 83 of the mutations were novel. This increase in the mutation rate was accomplished by combining rigorous clinical phenotyping, with a combination of mutation detection techniques, including fluorescence in situ hybridization (FISH), genomic and cDNA sequencing, and quantitative PCR. This higher rate of mutation identification has implications for clinical practice, facilitating genetic counseling, prenatal diagnosis, and evaluation of living-related liver transplant donors. Our results suggest that more aggressive screening may similarly increase the rate of mutation detection in other dominant and recessive disorders.

Abstract
OBJECTIVE To confirm the overall benefit of drug eluting stents (DES), to evaluate the effect of different DES, and to assess the global safety of DES compared with bare stents through a meta-analysis of randomised controlled trials. METHODS Randomised controlled trials comparing sirolimus and derivates or paclitaxel and derivates eluting stents versus bare stents. Binary restenosis and major adverse cardiac events (MACE) were chosen as primary end points. Death, Q wave myocardial infarction (MI), and stent thrombosis up to 12 months' follow up were also analysed. RESULTS MACE overall occurrence was highly reduced with DES from 19.9% to 10.1% (odds ratio (OR) 0.46, 95% confidence interval (CI) 0.41 to 0.52, p < 0.001). A significant heterogeneity (p < 0.001) was found between subgroups according to the drug: MACE OR was 0.28 (95% CI 0.22 to 0.35) in the sirolimus subgroup and 0.62 (95% CI 0.53 to 0.73) in the paclitaxel subgroup. Restenosis was also highly reduced from 31.7% with bare stents to 10.5% with DES (OR 0.25, 95% CI 0.22 to 0.29, p < 0.001) with a similar heterogeneity between subgroups. Mortality, Q wave MI, and stent thrombosis were not significantly different between DES and control group, whereas Q wave MI and stent thrombosis tended to be more frequent with paclitaxel. CONCLUSION This meta-analysis confirms the overall benefit of DES on restenosis and MACE with significant heterogeneity between drugs, suggesting higher efficacy of sirolimus eluting stents. Additional data with longer follow up and in high risk populations are needed to clarify issues on stent thrombosis.

Abstract
BACKGROUND AND OBJECTIVE The combination of non-opioid analgesic drugs, though widely used, has been rarely evaluated. The aim of this study was to compare the efficacy of propacetamol and the non-steroidal analgesic drug ketoprofen, alone or in combination, on pain relief after thyroid surgery performed using remifentanil. METHODS Ninety-seven patients were randomly allocated to one of the three groups: propacetamol 2 g (32), ketoprofen 100 mg (33) and propacetamol 2 g + ketoprofen 100 mg (32). Each regimen was administered intravenously (i.v.) 30 min before the end of surgery and then every 6 h. If pain was not relieved, patients received an i.v. bolus of tramadol 100 mg. Tramadol consumption and pain intensity using a visual analogue scale was recorded at 1, 2, 8 and 14 h after the end of surgery. RESULTS Pain scores were significantly higher with propacetamol compared with ketoprofen 2 h after surgery (35 +/- 3.7, 21 +/- 2.6, respectively; P < 0.01). The number of patients receiving tramadol was higher with propacetamol alone compared with the two other groups, 1 h (14/32, 4/33, 2/32, respectively; P > 0.01) and 2 h (24/32, 6/33, 8/32, respectively; P < 0.01) after surgery. There was no difference between ketoprofen alone and ketoprofen plus propacetamol, and there was no difference between the three groups from the 8th hour onward. CONCLUSIONS In the immediate postoperative period after thyroid surgery performed using remifentanil, the concomitant use of propacetamol and ketoprofen does not improve analgesia compared with ketoprofen alone.

Abstract
In the case of a soluble polymer supported synthesis, the tuning of the support solubility depending on the solvent offers new opportunities for combinatorial chemistry for two reasons. First, organic syntheses in solution are generally easily translated on a soluble polymer supported substrate. Second, complete automation of the three successive steps of combinatorial chemistry (synthesis, analytical control, biological test) is approached without releasing the synthesized compound from the support. We report in this paper the preliminary results toward automation of both soluble polymer supported syntheses and their subsequent monitoring by ESI mass spectrometry.
