Abstract
HYPOTHESIS The implementation of the proposal from the European Chemical Agency (ECHA) to restrict the use of nanoplastics (NP) and microplastics (MP) in consumer products will require reliable methods to perform size and mass-based concentration measurements. Analytical challenges arise at the nanometre to micrometre interface, e.g., 800 nm-10 µm, where techniques applicable at the nanometre scale reach their upper limit of applicability and approaches applicable at the micrometre scale must be pushed to their lower limits of detection. EXPERIMENTS Herein, we compared the performances of nine analytical techniques by measuring the particle size distribution and mass-based concentration of polystyrene mixtures containing both nano and microparticles, with the educational aim to underline applicability and limitations of each technique. FINDINGS Light scattering-based measurements do not have the resolution to distinguish multiple populations in polydisperse samples. Nanoparticle tracking analysis (NTA), nano-flowcytometry (nFCM) and asymmetric flow field flow fractionation hyphenated with multiangle light scattering (AF4-MALS) cannot measure particles in the micrometre range. Static light scattering (SLS) is not able to accurately detect particles below 200 nm, and similarly to transmission electron microscopy (TEM) and flow cytometry (FCM), is not suitable for accurate mass-based concentration measurements. Alternatives for high-resolution sizing and concentration measurements in the size range between 60 nm and 5 µm are tunable resistive pulse sensing (TRPS) and centrifugal liquid sedimentation (CLS), that can bridge the gap between the nanometre and micrometre range.

Abstract
AIMS The study was aimed to understand the depuration process of Cryptosporidium parvum and Toxoplasma gondii oocysts by zebra mussel (Dreissena polymorpha), to consider the use of the zebra mussel as a bioremediation tool. MATERIALS AND METHODS Two experiments were performed: (i) individual exposure of mussel to investigate oocyst transfers between bivalves and water and (ii) in vivo exposure to assess the ability of the zebra mussel to degrade oocysts. RESULTS (i) Our results highlighted a transfer of oocysts from the mussels to the water after 3 and 7 days of depuration; however, some oocysts were still bioaccumulated in mussel tissue. (ii) Between 7 days of exposure at 1000 or 10 000 oocysts/mussel/day and 7 days of depuration, the number of bioaccumulated oocysts did not vary but the number of infectious oocysts decreased. CONCLUSION Results show that D. polymorpha can release oocysts in water via (pseudo)faeces in depuration period. Oocysts remain bioaccumulated and infectious oocyst number decreases during the depuration period in zebra mussel tissues. Results suggest a degradation of bioaccumulated C. parvum and T. gondii oocysts. SIGNIFICANCE AND IMPACT OF THE STUDY This study highlighted the potential use of D. polymorpha as a bioremediation tool to mitigate of protozoan contamination in water resources.

Abstract
In cattle, antibodies to Toxoplasma gondii infection are frequently detected, but evidence for the presence of T. gondii tissue cysts in cattle is limited. To study the concordance between the presence of anti-T. gondii IgG and viable tissue cysts of T. gondii in cattle, serum, liver and diaphragm samples of 167 veal calves and 235 adult cattle were collected in Italy, the Netherlands, Romania and the United Kingdom. Serum samples were tested for anti-T. gondii IgG by the modified agglutination test and p30 immunoblot. Samples from liver were analyzed by mouse bioassay and PCR after trypsin digestion. In addition, all diaphragms of cattle that had tested T. gondii-positive (either in bioassay, by PCR on trypsin-digested liver or serologically by MAT) and a selection of diaphragms from cattle that had tested negative were analyzed by magnetic capture quantitative PCR (MC-PCR). Overall, 13 animals were considered positive by a direct detection method: seven out of 151 (4.6%) by MC-PCR and six out of 385 (1.6%) by bioassay, indicating the presence of viable parasites. As cattle that tested positive in the bioassay tested negative by MC-PCR and vice-versa, these results demonstrate a lack of concordance between the presence of viable parasites in liver and the detection of T. gondii DNA in diaphragm. In addition, the probability to detect T. gondii parasites or DNA in seropositive and seronegative cattle was comparable, demonstrating that serological testing by MAT or p30 immunoblot does not provide information about the presence of T. gondii parasites or DNA in cattle and therefore is not a reliable indicator of the risk for consumers.

Abstract
The two SIBLING (Small Integrin Binding Ligand N-linked Glycoproteins), bone sialoprotein (BSP) and osteopontin (OPN) are expressed in osteoblasts and osteoclasts. In mature BSP knockout (KO, -/-) mice, both bone formation and resorption as well as mineralization are impaired. OPN-/- mice display impaired resorption, and OPN is described as an inhibitor of mineralization. However, OPN is overexpressed in BSP-/- mice, complicating the understanding of their phenotype. We have generated and characterized mice with a double KO (DKO) of OPN and BSP, to try and unravel their respective contributions. Despite the absence of OPN, DKO bones are still hypomineralized. The SIBLING, matrix extracellular phosphoglycoprotein with ASARM motif (MEPE) is highly overexpressed in both BSP-/- and DKO and may impair mineralization through liberation of its ASARM (Acidic Serine-Aspartate Rich MEPE associated) peptides. DKO mice also display evidence of active formation of trabecular, secondary bone as well as primary bone in the marrow-ablation repair model. A higher number of osteoclasts form in DKO marrow cultures, with higher resorption activity, and DKO long bones display a localized and conspicuous cortical macroporosity. High bone formation and resorption parameters, and high cortical porosity in DKO mice suggest an active bone modeling/remodeling, in the absence of two key regulators of bone cell performance. This first double KO of SIBLING proteins thus results in a singular, non-trivial phenotype leading to reconsider the interpretation of each single KO, concerning in particular matrix mineralization and the regulation of bone cell activity.

Abstract
Preventing foodborne pathogen contamination of raw fruit and vegetables in the field is critically important for public health. Specifically, it involves preventing faecal deposit by wildlife or domestic animals in fields of crops and kitchen gardens. The present study aims to identify the drivers of fox, dog and cat faecal deposits in kitchen gardens in order to mitigate the risk of contamination of raw produce with parasites shed in carnivore faeces. The focus was on Echinococcus multilocularis, ranked highest in the importance of foodborne parasites in Europe, but attention was also paid to other parasites of major concern - Toxoplasma gondii and Toxocara spp. During the winters of 2014 to 2016, faecal samples were collected from 192 kitchen gardens located in north-eastern France. From these samples, 77% contained scat of carnivores. Molecular analyses revealed that 59% of the 1016 faeces collected were from cats, 31% from foxes, and 10% from dogs. The ease of accessibility to kitchen gardens, the presence of food in the vicinity, and the composition of the surrounding vegetation were used to explain the distribution of fox and cat faeces. Generalized Linear Mixed Effects modelling showed that: i) fencing was not efficient in reducing cat faecal deposits, but drastically decreases those of foxes; ii) the abundance of Microtus sp. indicates a reason for the presence of both fox and cat faecal deposits, iii) the abundance of Arvicola terrestris, the proximity of fruit trees or farms and the predominance of forest and grassland around the village are all drivers of fox faecal deposits. These results point to the importance of fencing around kitchen gardens located in E. multilocularis endemic areas, particularly those surrounded by forest and grassland or close to fruit trees or farms. 192 kitchen gardens sampled 6 times over 2 winters, 1016 carnivore faeces collected. Fencing, food and vegetation cover tested as explanatory factors for faeces location. Numerous cat faeces, even in enclosed gardens. Microtus sp. drives their deposit. Garden accessibility, food and vegetation cover drive the faecal deposits of foxes. Fencing off kitchen gardens should be encouraged in E. multilocularis endemic areas.

Abstract
Water quality is a public health concern that calls for relevant biomonitoring programs. Molecular tools such as polymerase chain reaction (PCR) are progressively becoming more sensitive and more specific than conventional techniques to detect pathogens in environmental samples such as water and organisms. The zebra mussel (Dreissena polymorpha) has already been demonstrated to accumulate and concentrate various human waterborne pathogens. In this study, first, a spiking experiment to evaluate detection levels of Toxoplasma gondii DNA in zebra mussel organs using real-time PCR was conducted. Overall, lower DNA levels in the hemolymph, digestive gland, and remaining tissues (gonad and foot) were detected compared to mantle, muscle, and gills. Second, an in vivo experiment with 1000 T. gondii oocysts per mussel and per day for 21 consecutive days, followed by 14 days of depuration time in protozoa-free water was performed. T. gondii DNA was detected in all organs, but greatest concentrations were observed in hemolymph and mantle tissues compared to the others organs at the end of the depuration period. These results suggest that (i) the zebra mussel is a potential new tool for measuring T. gondii concentrations and (ii) real-time PCR is a suitable method for pathogen detection in complex matrices such as tissues.

Abstract
Commissariat à l'Énergie Atomique et aux Énergies Alternatives has developed the ARGOS X-ray framing camera to perform two-dimensional, high-timing resolution imaging of an imploding target on the French high-power laser facility Laser MegaJoule. The main features of this camera are: a microchannel plate gated X-ray detector, a spring-loaded CCD camera that maintains proximity focus in any orientation, and electronics packages that provide remotely-selectable high-voltages to modify the exposure-time of the camera. These components are integrated into an "air-box" that protects them from the harsh environmental conditions. A miniaturized X-ray generator is also part of the device for in situ self-testing purposes.

Abstract
In order to calculate budgets of particulate matter and sediment-bound contaminants leaving the continental shelf of the Gulf of Lion (GoL), settling particles were collected in March 2011 during a major storm, using sediment traps. The collecting devices were deployed in the Cap de Creus submarine canyon, which represents the main export route. Particulate matter samples were analyzed to obtain mass fluxes and contents in organic carbon, Al, Cr, Co, Ni, Cu, Zn, Cd, Pb and La, Nd and Sm. The natural or anthropogenic origin of trace metals was assessed using enrichment factors (EFs). Results are that Zn, Cu and Pb appeared to be of anthropogenic origin, whereas Ni, Co and Cr appeared to be strictly natural. The anthropogenic contribution of all elements (except Cd) was refined by acid-leaching (HCl 1 N) techniques, confirming that Zn, Cu and Pb are the elements that are the most enriched. However, although those elements are highly labile (59-77%), they do not reflect severe enrichment (EFs <4). Most particles originate from the Rhone River. This has been confirmed by two different tracing procedures using rare earth elements ratios and concentrations of acid-leaching residual trace metals. Our results hence indicate that even in this western extremity of the GoL, storm events mainly export Rhone-derived particles via the Cap de Creus submarine canyons to the deep-sea environments. This export of material is significant as it represents about a third of the annual PTM input from the Rhone River.

Abstract
Cryptosporidium parvum, Giardia duodenalis and Toxoplasma gondii are ubiquitous pathogens, which waterborne transmission has been largely demonstrated. Since they can be found in various watercourses, interactions with aquatic organisms are possible. Protozoan detection for watercourses biomonitoring is currently based on large water filtration. The zebra mussel, Dreissena polymorpha, is a choice biological model in ecotoxicological studies which are already in use to detect chemical contaminations in watercourses. In the present study, the zebra mussel was tested as a new tool for detecting water contamination by protozoa. In vivo exposures were conducted in laboratory experiments. Zebra mussel was exposed to various protozoan concentrations for one week. Detection of protozoa was realized by Taqman real time qPCR. Our experiments evidenced C. parvum, G. duodenalis and T. gondii oocyst bioaccumulation by mussels proportionally to ambient contamination, and significant T. gondii prevalence was observed in muscle tissue. To our knowledge, this is the first study that demonstrates T. gondii oocyst accumulation by zebra mussel. The results from this study highlight the capacity of zebra mussels to reveal ambient biological contamination, and thus to be used as a new effective tool in sanitary biomonitoring of water bodies.

Abstract
For centuries, many Mediterranean catchments were covered with vineyards in which copper was widely applied to protect grapevines against fungus. In the Mediterranean-type flow regime, brief and intense flood events increase the stream water discharge by up to 10 times and cause soil leaching and storm runoff. Because vineyards are primarily cultivated on steep slopes, high Cu fluxes are discharged by surface water runoff into the rivers. The purpose of this work was to investigate the riverine behavior and transport of anthropogenic Cu by coupling a sequential chemical extraction (SCE) procedure, used to determine Cu partitioning between residual and non-residual fractions, with δ(65)Cu isotopic measurements in each fraction. In the Baillaury catchment, France, we sampled soils (cultivated and abandoned), river bed sediments (BS), suspended particulate matter (SPM), and river water during the flash flood event of February 2009. Copper partitioning using SCE show that most of Cu in abandoned vineyard soil was in the residual phase (>60%) whereas in cultivated soil, BS and SPM, Cu was mostly (>25%) in non-residual fractions, mainly adsorbed onto iron oxide fractions. A small fraction of Cu was associated with organic matter (5 to 10%). Calculated enrichment factors (EF) are higher than 2 and the anthropogenic contribution was estimated between 50 to 85%. Values for δ(65)Cu in bulk samples were similar to bedrock therefore; δ(65)Cu on SCE fractions of superficial soils and SPM allowed for discrimination between Cu origin and distribution. Copper in residual fractions was of natural mineral origin (δ(65)Cu close to local bedrock, +0.07‰). Copper in water soluble fraction of SPM (δ(65)Cu=+0.26‰) was similar to dissolved river Cu (δ(65)Cu=+0.31‰). Copper from fungicide treatment (δ(65)Cu=-0.35‰) was bound to organic matter (δ(65)Cu=-0.20‰) without or with slight isotopic fractioning. A preferential adsorption of (65)Cu onto iron oxides (δ(65)Cu=+0.5‰) is shown.

Abstract
Toxoplasma gondii, Cryptosporidium parvum, and Giardia duodenalis are human waterborne protozoa. These worldwide parasites had been detected in various watercourses as recreational, surface, drinking, river, and seawater. As of today, water protozoa detection was based on large water filtration and on sample concentration. Another tool like aquatic invertebrate parasitism could be used for sanitary and environmental biomonitoring. In fact, organisms like filter feeders could already filtrate and concentrate protozoa directly in their tissues in proportion to ambient concentration. So molluscan shellfish can be used as a bioindicator of protozoa contamination level in a site since they were sedentary. Nevertheless, only a few researches had focused on nonspecific parasitism like protozoa infection on aquatic invertebrates. Objectives of this review are twofold: Firstly, an overview of protozoa in worldwide water was presented. Secondly, current knowledge of protozoa parasitism on aquatic invertebrates was detailed and the lack of data of their biological impact was pointed out.

Abstract
Delivery of recombinant adeno-associated virus (rAAV) vectors to the newborn liver is followed by a rapid loss of episomal vector copies because of hepatocyte proliferation. In selected hepatocytes, integration of rAAV genomes can lead to a sustained expression of the transgene. The safety of in vivo gene therapy with single-stranded AAV vectors has been questioned in a study reporting a high incidence of hepatocellular carcinoma, associated with provirus integration events in mice that receive an single-stranded AAV injection at birth. To investigate the tumour-initiating potential of the newly established self-complementary AAV (scAAV) vectors in the liver, groups of newborn rats received intravenous injection of a scAAV vector encoding the green fluorescent protein (GFP), or were injected with phosphate-buffered saline (PBS) or diethylnitrosamine (DEN), a well-known liver tumour initiator. The rats were fed on a diet containing 2-acetylaminofluorene, a potent liver tumour-promoting agent to accelerate the carcinogenic process. After 2 months, the animals were killed and their livers analysed. Preneoplastic nodules were identified by glutathion S-transferase-p (GSTp) staining, and GFP expression was detected by immunohistochemistry. Vector genome integration events were analysed. The numbers of GSTp-positive foci were comparable in the PBS and the scAAV-GFP groups and significantly higher in the DEN group. The proportion of GSTp-positive foci that also expressed GFP was low and in the range expected for random occurrence. No specific integration hot spots were detected by linear amplification-mediated-PCR in transduced liver. In conclusion, scAAV transduction of newborn rat liver does not trigger preneoplastic lesions suggesting an absence of liver tumourigenesis.

Abstract
Toxoplasma gondii isolates have been classified into 3 genetic types. Little is known about genotypes of T. gondii isolates in wild animals in Europe. In this report, genotypes of T. gondii isolates from wildlife in France are described. Sera from wildlife were tested for antibodies to T. gondii with the modified agglutination test, and the hearts from animals with titers superior or equal to 1:6 were bioassayed individually in mice. T.gondii was isolated from 9 of 14 seropositive red foxes (Vulpes vulpes), 12 of 33 roe deer (Capreolus capreolus), 1 of 4 deer (Cervus elaphus), 1 of 7 mouflons (Ovis gmelini musimon) and 1 of 2 common mallards (Anas platyrhynchos). No isolate was obtained by bioassay in mice of 1 fallow deer (Dama dama) and of 3 European brown hares (Lepus europaeus). Genotyping of the 24 isolates using PCR-RFLP and microsatellite markers indicated that all were type II and none of these Toxoplasma isolates was virulent for mice.

Abstract
OBJECTIVE To determine the efficiency and the role of ureteroscopy in the treatment of urolithiasis in children. METHODS A multicenter retrospective study was conducted between January 2006 and March 2008 in the department of pediatric surgery and urology of Besançon, Lyon and Grenoble. The clinical data of 17 children having benefited from one or more ureteroscopy procedures for urolithiasis were analyzed. These data concerned age, sex, antecedents of metabolic diseases, existence of a malformed uropathy, how the urolithiasis was discovered, therapeutic indications, endoscopic procedures, type of endoscopic treatment for urolithiasis, results and complications. RESULTS Twenty-six ureteroscopies were carried out for 17 children (eight girls and nine boys) aged between 9 months and 12 years (mean: 5 (1/2) years old) as a first-line treatment or after extracorporeal shock wave lithotripsy. A 6/7,5 Fr semi-rigid ureteroscope was used in all case. Only once, the operator chose a flexible ureteroscope. Lithotripsy was carried out 15 times with YAG Holmium laser, four times with Swiss Lithoclast and six times by simple extraction with a Dormia type basket .A stent probe was left in place after endoscopy for 14 children. The "stone free" rate was 88% with an average hindsight of 11 months. Two incidents without major complication were recorded: a section of the guide by the laser beam and a perforation with extravasation of the contrast agent. CONCLUSION Ureteroscopy is the first-line treatment in isolated ureteral urolithiasis. On the other hand, LEC remains the treatment of choice for Starghon calculi, since LIC should be offered only in the event of failure of LEC.

Abstract
BACKGROUND To evaluate the impact of scientific seminar on the sexual ambiguity on patients and paediatric surgeons in French-speaking African countries. MATERIALS AND METHODS This was a report of the proceeding of a teaching seminar on intersex management, which was held from December 4 th to 8 th , 2006, in the Paediatric Surgery Department of Tokoin Teaching Hospital and the Surgery Department of "Saint Jean de Dieu" Hospital of Afagnan, Togo. RESULTS There were 107 participants [five professors of paediatric surgery, 62 African paediatric surgeons (including 15 from African French-speaking countries), and 40 general surgeons]. The workshop involved a two-day theoretical teaching session (aimed at understanding, recognising, and treating the sexual ambiguities), and practical session; during these sessions different intersexes (one case of mixed gonadal dysgenesis, two of female pseudohermaphroditism, and two of male pseudohermaphroditism), were operated free of charge. Participants expressed satisfaction and confidence with regard to the management of intersex after the seminar. CONCLUSION This scientific forum allowed possible exchange of competence among the paediatric surgeons with regard to efficient treatment of sexual ambiguities.

Abstract
Toxoplasma gondii strains isolated from domestic animals and humans have been classified into three clonal lineages types I-III, with differences in terms of pathogenicity to mice. Much less is known on T. gondii genotypes in wild animals. In this report, genotypes of T. gondii isolated from wild boar (Sus scrofa) in France are described. During the hunting seasons 2002-2008, sera and tissues of individuals from two French regions, one continental and one insular, were tested for Toxoplasma infection. Antibodies to T. gondii were found in 26 (17.6%) of 148 wild boars using the modified agglutination test (MAT, positivity threshold: 1:24). Seroprevalence was 45.9% when considering a threshold of 1:6. Hearts of individuals with a positive agglutination (starting dilution 1:6) (n=60) were bioassayed in mice for isolation of viable T. gondii. In total, 21 isolates of T. gondii were obtained. Genotyping of the isolates using 3 PCR-restriction fragment length polymorphism markers (SAG1, SAG2 and GRA7) and 6 microsatellite loci analysis (TUB2, TgM-A, W35, B17, B18 and M33) revealed that all belonged to type II lineage. These results underline that wild boar may serve as an important reservoir for transmission of T. gondii, and that strains present in wildlife may not be different from strains from the domestic environment.

Abstract
To determine whether hypoxia has a direct influence on the central command independently of the working muscles, 16 subjects performed intermittent isometric unilateral knee extensions until exhaustion either in normobaric hypoxia (inspired O(2) fraction=0.11, arterial oxygen saturation approximately 84%) or in normoxia while the knee extensor muscles were exposed to circulatory occlusion with a 250 mmHg cuff. Among the subjects, 11 also performed the tests in hypoxia and normoxia without occlusion. Single electrical stimulations were regularly delivered to the femoral nerve to measure the changes in the knee extensor peak twitch force. With the cuff, the average slope of decrease in peak twitch did not depend on the inspired oxygen fraction. Performance was slightly but significantly lower during hypoxia than in normoxia (8.2+/-2.6 vs 9.4+/-3.1 repetitions, P<0.05) with the cuff on. The number of repetitions was much higher during hypoxia with maintaining leg blood flow (15.6+/-4.5 repetitions) than with circulatory occlusion in normoxia. In conclusion, this study showed that a direct effect of hypoxia in reducing the motor drive to the working muscles exists but this effect is moderate.

Abstract
PURPOSE To evaluate the accuracy of voiding urosonography (VUS) compared to X-ray voiding cystoureterography (VCUG) for the detection and grading of vesicoureteral reflux (VUR) by standardised reading of digital clips obtained from VUS and digital images from VCUG. MATERIALS AND METHODS Approval by the ethics committee was obtained, and written, informed consent was given. 130 children (94 girls and 36 boys, mean age of 4.4 years) underwent VUS using Levovist (Schering, Germany) prior to VCUG. Digital VUS clips and digital VCUG images were reviewed by two groups of two radiologists. Results were mainly analysed in terms of reno-ureteral units (RUUs). Intra and interobserver reproducibility was estimated by calculation of kappa coefficient. Calculation of sensitivity and specificity of VUS was made in comparison with VCUG. RESULTS Intraobserver reproducibility was good to moderate for the detection of VUR using VUS (kappa = 0.67 and 0.53 for each reviewer respectively) and good for the grading of reflux (kappa = 0.64 and 0.70). Interobserver reproducibility was excellent for the detection and grading of VUR using VCUG (kappa = 0.89 and 0.91) but good to moderate for VUS (kappa = 0.73 and 0.51). Compared to VCUG, sensitivity and specificity of VUS for the detection of VUR were 62.7 % and 83.4 %. Concordance for grading was moderate, with a higher grading using VUS. CONCLUSION Real-time evaluation and diagnosis based on the review of VUS digital clips is achievable. However, there is a need for standardisation of digital records if a second reading by another radiologist or consideration by urologists is needed. Recent advances in US technology and the use of second-generation contrast agents would be promising to improve the feasibility, reproducibility and accuracy of the method.

Abstract
Among inherited diseases of the liver, Crigler-Najjar type 1 disease (CN-1), which results from complete deficiency in bilirubin UDP-glucuronosyltransferase activity (B-UGT1), is an attractive target for gene therapy studies. Hyperbilirubinemic Gunn rats, a model of CN-1, were injected at 2 days of age with lentiviral or oncoretroviral vectors encoding the human B-UGT1. After injection, bilirubinemia was normalized for up to 95 weeks. Bilirubin conjugates were present in the bile, demonstrating liver transduction. PCR and enzyme activity analysis confirmed gene and phenotype correction in liver. We observed that when using a strong viral promoter, a complete correction was achieved with less than 5% of B-UGT1 copy per haploid genome and after a reconstitution of 12% B-UGT1 normal activity. Liver histology remained normal throughout the experiment and tissue distribution analysis revealed preferential hepatocyte transduction after systemic delivery. Finally, no adverse immune response occurred even after induction of nonspecific liver inflammation, suggesting immune ignorance to the therapeutic protein. Our present results document the lifelong safety of gene therapy for CN-1 with retroviral vectors. They offer a better delineation of liver gene correction level required to achieve complete correction of bilirubinemia and pave the way for future clinical application of gene therapy for inherited liver disorders.

Abstract
1056 Background: Oral chemotherapy (CT) is attractive for patients (pts) with MBC. The all-oral regimen of NVBo and X is active with good tolerability in MBC. We report efficacy and safety data from an international phase II study of NVBo plus X. Methods: Main eligibility criteria included: measurable HER2-negative, CT-naive MBC, relapse ≥6 months after completing (neo)adjuvant CT, Karnofsky PS ≥70%, age ≥18 years. Study treatment: 3-weekly cycles of NVBo 60 mg/m2 (cycle 1) or 80 mg/m2 (from cycle 2) d1 and d8, plus X 1,000 (750 if ≥ 65 years) mg/m2 twice-daily d1–14. Treatment was continued until progression or unacceptable toxicity. Results: 55 pts were enrolled: median age: 58.5 years (41% ≥65); prior (neo)adjuvant CT in 63%; type of CT: anthracycline 67%, anthracycline + taxane 18%, CMF 15%; visceral involvement in 78%; >2 metastatic sites in 46%. Median 6 cycles; median relative dose intensity: NVBo 88%, X 87%; NVBo dose escalated to 80 mg/m2 in 94% of pts. G3/4 NCI CTC v2 adverse events (n=54): neutropenia 44% of pts, vomiting 9%, febrile neutropenia 7%, stomatitis 7%, asthenia 7%, infection with G3/4 neutropenia 4%, nausea 4%, diarrhea 4%, hand-foot syndrome 4%, thrombosis/embolism 4%. Efficacy (n=48 evaluable pts): objective response rate (RECIST) 44% (95% CI [29–59]), CR 2%, PR 42%, SD 35%, PD 21%, disease control (CR+PR+SD ≥6 months) 56%. Median time to objective response was 2.9 months. Because of short follow-up, progression-free survival, overall survival and duration of response data are not yet available. Conclusion: The all-oral combination of NVBo and X is an effective and well-tolerated first-line therapy for MBC. Based on these results and the high convenience of oral CT, evaluation of this regimen vs i.v. combinations in a randomized trial is ongoing. [Table: see text]

Abstract
1052 Background: Chemotherapy (CT) plus H is the standard first-line treatment for HER2-positive MBC. H plus vinorelbine is an active and well-tolerated regimen in this setting. The all-oral combination of NVBo and X also appears active and well-tolerated in MBC. We report efficacy and safety results from the first 34 patients (pts) included in an international trial evaluating NVBoXH in HER2-positive MBC. Methods: In this multicenter trial, main eligibility criteria included: HER2-positive disease (IHC 3+ or FISH+), documented measurable MBC previously untreated by CT, relapse 6 months after completing neoadjuvant or adjuvant CT, Karnofsky PS = 70, age =18 years. Pts received 3-weekly cycles of NVBo 60 mg/m2 (cycle 1) escalating to 80 mg/m2 (from cycle 2) days 1 and 8; × 1,000 mg/m2 bid (750 if = 65 years) days 1–14; H 4 mg/kg day 1 as a loading dose then 2 mg/kg i.v. weekly starting on day 8. Treatment was continued until progression or unacceptable toxicity. Primary endpoint is overall response rate. Results: Baseline characteristics: median age 54 years (20% = 65); prior (neo)adjuvant CT 21 pts (62%); type of CT: anthracycline 52%, anthracycline + taxane 29%, CMF 14%, taxane 5%; visceral involvement 29 pts (85%), >2 metastatic sites 13 pts (38%). Treatment administered: median 8 cycles, median relative dose intensity: NVBo 77%, X 81%, H 95%; NVBo dose escalation to 80 mg/m2 in 91% of pts. Safety (n=34, G3/4 NCI CTC v2 adverse events): neutropenia 22 pts (65%), diarrhea 4 pts (12%), febrile neutropenia 3 pts (9%), vomiting 3 pts (9%), hand-foot syndrome 3 pts (9%), asthenia 3 pts (9%), infection without neutropenia 2 pts (6%), LVEF decline 2 pts (6%), stomatitis 1 pt (3%), nausea 1 pt (3%), constipation 1 pt (3%). Efficacy (n=31 evaluable pts): objective response rate (RECIST) 71% (95% CI [52–86]), CR 13%, PR 58%, SD 23%, PD 6%, disease control (CR+PR+ SD for =6 months) 84%. Progression-free survival, overall survival and duration of response data are not yet mature. Conclusions: This is the first trial, in pts with HER2-positive MBC, to show high efficacy with first-line NVBoXH therapy. This regimen can be safely administered in this pt population. No significant financial relationships to disclose.

Abstract
PURPOSE Spina bifida (SB) is the most common congenital cause of incontinence in childhood. This study attempts to determine the relationships between urinary/faecal incontinence, methods of management, and Health Related Quality of Life (HRQoL) in people with SB. PATIENTS AND METHOD A total of 460 patients (300 adults and 160 adolescents) from six centres in France have taken part in this cross-sectional study. Clinical outcome measures included walking ability, urinary/faecal continence, and medical management. HRQoL was assessed using the SF36 in adults and the VSP in adolescents and their parents. Univariate and multivariate analysis was used to determine the relationships between clinical parameters and HRQoL. RESULTS HRQoL were significantly lower than in the general population. Adult women had significantly lower scores than men, and adolescent females had significantly lower scores for psychological well being. We did not found strong relationship between incontinence and HRQoL in this population. Moreover patients surgically managed for urinary/fecal incontinence did not show significantly higher scores of HRQoL. CONCLUSION Using generic HRQoL measures, urinary/faecal incontinence and their medical management may not play a determinant role in HRQoL of persons with SB. However many other factors affect HRQoL in these patients. A longitudinal study design is recommended to assess whether incontinence management is associated with improved HRQoL.

Abstract
The aim of this international phase II trial was to determine the efficacy and safety profile of weekly vinorelbine plus trastuzumab as first-line chemotherapy for women with HER 2-overexpressing metastatic breast cancer. Sixty-nine patients with tumours overexpressing HER 2 received vinorelbine: 30 mg m−2 week−1 and trastuzumab: 4 mg kg−1 on day 1 as a loading dose followed by 2 mg kg−1 week−1 starting on day 8. Sixty-two patients were evaluable for response and 69 patients were evaluable for toxicity. The overall response rate was 62.9%. The median time to response was 8.4 weeks, the median duration of response was 17.5 months, the median progression-free survival was 9.9 months (95% CI, 5.6–12.1) and the one-year progression-free survival was 39.1%. The median survival for all patients was 23.7 months (95% CI, 18.4–32.6). This regimen was safe: grade 3–4 neutropenia were observed over 17.7% of courses in 83.8% of patients, with only two episodes of febrile neutropenia (0.1%) in two patients (2.9%). Only one patient discontinued treatment due to grade 3 symptomatic cardiac dysfunction that resolved with therapy. Vinorelbine plus trastuzumab is one of the most active treatment regimens for patients with HER 2-positive metastatic breast cancer and demonstrates a very favourable safety profile allowing prolonged treatment with long-term survival. This study has been presented in part at the following conferences: The San Antonio Breast Cancer Symposium, San Antonio, TX, USA, 2003; The American Society of Clinical Oncology, Orlando, FL, USA, 2005.

Abstract
7126 Background: NVB i.v. day 1 (25 mg/ m2) & NVBo day 8 (60 mg/ m2) and CBDCA AUC 5 have been previously studied in chemonaive NSCLC patients (pts) (O’Brien et al, Ann Oncol 2004; 15: 921). We investigated the efficacy and safety of NVBo weekly with CBDCA AUC 5 q3w for 4 cycles(Cy) followed by maintenance therapy with single agent NVBo in non progressive pts. Methods: Inoperable NSCLC stage IIIB, stage IV or delayed relapse of any stage becoming unresectable, KPS ≥ 80%, treated with combination therapy every 3 weeks for 4 Cy: NVBo 60 mg/m2 on days 1, 8 and 15 (Cy1), 80 mg/m2 (Cy2–4) in absence of neutropenia NCI CTC V2 G3/4; CBDCA AUC 5 day 1, administered over 1 hour. Maintenance therapy if pts did not have a PD: NVBo 60 mg/m2 for the first three weekly administrations, followed by NVBo at 80 mg/m2/week until PD. Results: from December 2003 to January 2005 57/56 pts have been registered/treated: median age 61 yrs (37–71); median KPS 90%; male 71.4%; Squamous cell 30%, Adenocarcinoma 50%; Stage III/IV 32.1/62.5% ; median dose intensity NVBo (% RDI) : combination, 50.1 mg/m2/w (67.3%), maintenance 56.2 mg/m2/w (70.2%); pts with NVBo dose escalation from 60 to 80 mg/m2 during combination : 36/52 (69.2%). Tolerance (% of pts with G3/4 NCI CTC V2) : Neutropenia 23.2/44.6; Platelets 16.1/1.8; Hb 19.6/3.6; Nausea 7.1/0; Vomiting 7.1/0; Diarrhea 5.4/0. No G3/4 toxicity was reported for Infection, Bilirubin, Creatinine, Stomatitis, and motor/sensory Neuropathy. Febrile Neutropenia was reported in 5 patients (8.9%). Efficacy: (RECIST) Percent Overall Response rates (n =56 pts) PR 17.9, SD 53.6, PD 23.2, NE 5.4; Progression-Free Survival 4.3 (95% CI [3.1–5.1]) months; Overall Survival 9.7 (95% CI [7.7–11.9]) months. Conclusions: NVBo on a weekly schedule and CBDCA AUC5 in combination therapy for 4 Cy followed by NVBo in maintenance therapy is an effective and safe treatment regimen for advanced NSCLC. The avoidance of further CBDCA administrations after 4 Cy and the use of NVBo as a maintenance therapy until PD has promise as an alternative to the 6 Cy option and calls for further comparative studies.

Abstract
10607 Background: Combination therapy of T and Vinorelbine has recently been reported to be an active and safe regimen for HER2 positive MBC pts. The current safety analysis investigated NBVo and C, which offers the convenience of an all-oral regimen given alone or in combination with T, if pts were HER2 positive, as first-line therapy for MBC patients, KPS ≥ 70%. Methods: In the HER2 negative study ([A]) (IHC 0- 2+/FISH−) 38 pts received: NVBo 60 mg/m2 (Cycle 1) or 80 mg/m2 (from Cycle 2) D1 & D8 and C 2000 (1500 if ≥ 65 y) mg/m2/d D1-D14 every 3 weeks. In the HER2 positive study ([B]) (IHC 2+ or 3+ confirmed by FISH+) 25 pts received : NVBo, and C at the same doses as [A] + T, 4 mg/kg on D 1 as loading dose and then 2 mg/kg i.v. weekly starting on D8. Treatment was continued in both studies till progression. Results: Median age: [A] 61.5y (17 pts ≥ 65 y), [B] 53.0 y (5 pts ≥ 65 y); Prior (neo)adjuvant CT: [A] 21 pts (55.3%), [B] 16 pts (64%); Visceral involvement: [A] 28 pts (73.7%), [B] 22 pts (88%); > 2 metastases: [A] 15 pts (39.5%), [B] 10 pts (40%); Median dose intensity (%): NVBo [A] 45.1 mg/m2/w (90.5%), [B] 39.5 mg/m2/w (75.7%); C [A] 7733 mg/m2/w (87%), [B] 7140 mg/m2/w (83.7%); T [B] 2.1 mg/kg/w (98.1%). NVBo dose escalation to 80 mg/ m2: [A] 33 pts (94.3%), [B] 23 pts (92%). Tolerance: ([A] n = 38 pts, [B] n = 25 pts) (% of pts with G3/4 NCI CTC v2): Neutropenia [A] 29/16, [B] 52/16; Infection with G3/4 neutropenia [A] 3/3, [B] 8/0; Stomatitis [A] 5/3, [B] 0/4; Bilirubin [A] 3/0, [B] 0/0; HF Syndrome [A] 3/0, [B] 8/0; Nausea [A] 3/0, [B] 0/4; Vomiting [A] 10/0, [B] 4/4; Diarrhoea [A] 5/0, [B] 12/4; Ileus [A] 0/0, [B] 4/0; Febrile Neutropenia: [A] 5%, [B] 8%. Efficacy: the preliminary results on the evaluable pts confirm an optimal disease control (CR + PR + SD): [A] 25/27 pts (92.6%), [B] 22/24 pts (91.7%). Conclusion: The combination of NVBo and C can be safely administered in the palliative setting of MBC and calls for further comparative studies vs i.v. combinations. The addition of T in HER2 positive patients does not alter the favourable safety profile. [Table: see text]

Abstract
The apicomplexan Toxoplasma gondii, an obligate intracellular parasite, can infect humans and a wide range of vertebrates leading to toxoplasmosis. This generally benign affection can causes severe life-threatening disease, particularly in immunocompromised patients and in children with congenital toxoplasmosis. Our research team works on cell-host-parasite interactions by studying biodiversity, pathogenic mechanisms and environment. We search to identify prognostic factors of disease and markers of resistance. This project is an integral part of our Research Institute (IFR53) which receives support from the Toxoplasma Biological Resource Center for constituting a bank of well characterized toxoplasma isolates for genotyping, clinical and epidemiological data. The involvement of metalloproteinases implicated during monocytic cell invasion and identification of ABC transporter proteins in T. gondii, factors implicated in resistance, need to be explored.

Abstract
PURPOSE We describe urinary continence management and outcome in patients with spina bifida to identify the procedures that are most successful. MATERIALS AND METHODS In a multicenter retrospective cohort study medical charts were studied. At the same time in a cross-sectional survey sociodemographic characteristics, orthopedic features and urinary continence were described based on the frequency of leakage from the viewpoint of patients or close relatives using a Likert scale of 5 items, namely 1-leakage permanent to 5-leakage never. RESULTS A total of 421 patients were included, of whom 191 (45%) had been medically treated with a normal voiding pattern according to the patient viewpoint in 21%, clean intermittent catheterization in 61% and no specific bladder emptying method in 18%. The mean leakage score +/- SD was 2.74 +/- 1.55. On the other hand, 230 patients (55%) were surgically treated. Except for 23 patients who underwent noncontinent urinary diversion 207 were considered for treatment and continence description. The mean leakage score was 3.45 +/- 1.60. An artificial urinary sphincter in male and females, and a sling or Kropp technique in females were satisfactory when bladder enlargement was not required. In cases of bladder augmentation without continent diversion an artificial urinary sphincter in males and a bladder neck sling or cinch, Kropp and Young-Dees procedures in females have provided the best results. In cases of bladder enlargement with continent urinary diversion bladder neck closure or a wrap have provided the best results whatever the patient sex. CONCLUSIONS Many factors may influence the choice of a technique, such as patient sex, bladder characteristics or orthopedic conditions. However, since to our knowledge no randomized, controlled study has been yet performed, definitive conclusions on the best way to achieve urinary continence in patients with spina bifida cannot be established.

Abstract
Patients with spinal dysraphism may have severe constipation and faecal incontinence. The impact of antegrade colonic enema (ACE) in the management of patients with spina bifida (SB) is analysed. In a multicentre cross-sectional study, constipation, faecal incontinence and faecal management were described. Cases surgically treated were identified. Data were collected from 423 patients, of whom 230 did not use any manoeuvre or laxatives to assist evacuation. Conventional treatment was used in 193 patients, including digital extraction in 39%, retrograde enema in 21% and oral laxatives in 52%. For intractable constipation and overflow of faecal incontinence, 47 patients were treated with ACE, of whom 41 used the method at a mean time of interview of 4.1 +/- 1.9 years after ACE operation; six abandoned ACE for conventional management. With ACE, faecal continence was significantly improved compared with conventional management, and neither retrograde rectal enema nor digital extraction were required. The conduit was fashioned to the right colon in 32 cases and to the left colon in nine cases. This study provides information on a multicentre experience in bowel management in SB patients. Whatever the technique used, ACE has improved faecal status compared with conventional therapy.

Abstract
Duodenal obstruction by Superior Mesenteric Artery (SMA) is a misdiagnosed vomiting syndrome in children. Several factors are involved, including rapid weight loss, rapid statural growth without weight augmentation. Diagnosis is suspected when an improvement is achieved by ventral decubitus and it is confirmed by plain films of the abdomen, GI study with barium and echography, measuring the aortomesenteric angle (inferior to 25-30 degrees ). Patients must at first be treated conservatively. Surgery is indicated for occlusive episodes with unsuccessful conservative therapy. The authors report 3 cases with different clinical presentation. However, all the patients presented important weight loss and vomiting.

Abstract
We present the first direct measurement of the time evolution of the gain of a soft x-ray laser amplifier. The measurement is based on the injection of a seed pulse, obtained by high-order harmonic generation, into an x-ray laser medium. Strong amplification occurs when the seed pulse is synchronized with the gain period. By precisely varying the delay between the x-ray laser plasma creation and the seed pulse injection, the actual temporal evolution of the soft x-ray amplifier gain is obtained with a subpicosecond resolution.

Abstract
Vinorelbine intravenously (i.v.) demonstrated its efficacy and tolerability in advanced non-small cell lung cancer (NSCLC) patients, including elderly subjects. Since vinorelbine is now available as an oral formulation this phase II open study was designed to evaluate its activity and tolerability in advanced, elderly NSCLC patients. A total of 56 chemonaive patients were recruited from April 2001 through to March 2002. The dosage schedule, already tested in younger NSCLC patients, was 60 mg/m(2)once a week for three weeks (first cycle), followed by 80 mg/m(2) once a week until disease progression or development of unacceptable toxicity. A limited sampling scheme was used for performing pharmacokinetic analysis on 52 of 56 patients enrolled in the study. Treatment was well tolerated with grade 3/4 neutropenia in 11/17 patients (20/30%) and febrile neutropenia in 1 (2%). Six partial responses (11%) and 25 stable disease responses were recorded, with a disease control rate of 55%. Median overall survival was 8.2 months (95% Confidence Interval (CI) [6.2-11.3]). The clinical benefit response rate was 31% on 32 evaluable patients. Pharmacokinetic profiles appeared quite similar to the historical profiles recorded following i.v. administration. Oral vinorelbine appears to be a reasonable alternative to i.v. vinorelbine, both in terms of activity and tolerability, in advanced, elderly NSCLC patients.
