Abstract
OBJECTIVES In France, the prevalence of gout is currently unknown. We aimed to design a questionnaire to detect gout that would be suitable for use in a telephone survey by non-physicians and assessed its performance. METHODS We designed a 62-item questionnaire covering comorbidities, clinical features and treatment of gout. In a case-control study, we enrolled patients with a history of arthritis who had undergone arthrocentesis for synovial fluid analysis and crystal detection. Cases were patients with crystal-proven gout and controls were patients who had arthritis and effusion with no monosodium urate crystals in synovial fluid. The questionnaire was administered by phone to cases and controls by non-physicians who were unaware of the patient diagnosis. Logistic regression analysis and classification and regression trees were used to select items discriminating cases and controls. RESULTS We interviewed 246 patients (102 cases and 142 controls). Two logistic regression models (sensitivity 88.0% and 87.5%; specificity 93.0% and 89.8%, respectively) and one classification and regression tree model (sensitivity 81.4%, specificity 93.7%) revealed 11 informative items that allowed for classifying 90.0%, 88.8% and 88.5% of patients, respectively. CONCLUSIONS We developed a questionnaire to detect gout containing 11 items that is fast and suitable for use in a telephone survey by non-physicians. The questionnaire demonstrated good properties for discriminating patients with and without gout. It will be administered in a large sample of the general population to estimate the prevalence of gout in France.

Abstract
BACKGROUND The study aims were to assess the association of microflora between the paranasal sinus and the lower airways of children attending a regional paediatric cystic fibrosis centre and to determine the performance of an eradication treatment protocol for positive paranasal sinus samples. METHOD Paired nasal lavage and lower airway samples (cough swabs or sputum) were taken from 54 children with cystic fibrosis (median age 11 years). Positive paranasal sinus samples received eradication treatment, using oral and sinonasal nebulised antibiotics. RESULTS A correlation between paranasal sinus and lower airways was detected in 33/54 paired timed samples (p<0.02). Of 4/54 children who reported sinus symptoms, only 2 had paranasal sinus positive samples. 28 positive nasal lavage samples cultured 8 Pseudomonas aeruginosa (PA), 8 Staphylococcus aureus (SA) and 12 other bacterial pathogens. Eradication using sinonasal nebulised antibiotics and oral antibiotics showed a success of 14/21 (67%) treated paranasal sinus positive samples at 1 month & 3 months after treatment. Success rate was 75% in the PA group and 71% in the SA group. Ongoing monitoring with nasal lavage will continue. CONCLUSION There was agreement between pathogens or lack of them found in the paranasal sinus and lower airways. Paranasal infection is often asymptomatic in children with cystic fibrosis. The eradication protocol for paranasal sinus pathogens had a good success rate.

Abstract
In Belgium, where haemophilia affects approximately 1:7000 people (2011), data on patients' quality of life (QoL) is scarce. This project aims to assess physical and mental QoL (P-QoL and M-QoL) simultaneously, and to analyse the influence of different variables on these two aspects of QoL. After Ethics Committee approval, we contacted 84 adult haemophilia A (HA) and haemophilia B (HB) patients, without current inhibitors, on replacement therapy (on-demand or secondary prophylaxis), regularly followed up at our comprehensive treatment centre. Seventy-one (n = 59 HA, n = 12 HB) replied to our questionnaire, which included the SF36v2 QoL assessment forms. We analysed two groups of variables: one including variables previously associated with decreased QoL, and another including variables with unclear impact on QoL (e.g., patients' understanding of haemophilia-related issues, economical concerns). In our population (mean ± SD age: 45.2 ± 14.7 years old), P-QoL appeared more reduced than M-QoL. P-QoL was strongly influenced by the number of arthropathies while M-QoL was primarily affected by patients' concern of personal costs due to haemophilia. Among this latter group, having knowledge of insurance coverage had a positive impact on M-QoL. Scores did not depend on haemophilia type. QoL was impaired in our haemophilia patients. A simultaneous assessment of P-QoL and M-QoL confirmed the benefit of primary prophylaxis in P-QoL, while originally pointing out the major burden of patients' concerns and poor understanding of haemophilia-related economical issues on their M-QoL. This might become a particularly challenging issue in times of financial crisis.

Abstract
Darbepoetin (DAR), with or without granulocyte colony-stimulating factor (G-CSF), has proved effective in treating anemia in patients with lower-risk myelodysplastic syndrome (MDS), but its effects on quality of life (QoL) and exercise functioning are less well established. In this phase II study (no. NCT00443339), lower-risk MDS patients with anemia and endogenous erythropoietin (EPO) level <500 IU/L received DAR 500 μg once every 2 weeks for 12 weeks, with G-CSF added at week 12 in non-responders. Physical performance was assessed with the 6-min walking test and, for fit patients, maximal oxygen consumption (VO2max). QoL was evaluated using SF-36 and FACT-An tests. In 99 patients, erythroid response rate according to IWG 2006 criteria was 48 and 56 % at 12 and 24 weeks, respectively. Addition of G-CSF rescued 22 % of non-responders. In 48 % of the responders, interval between darbepoetin injections could be increased for maintenance treatment. Serum EPO level was the only independent predictive factor of response at 12 weeks, and its most discriminant cutoff value was 100 IU/L. QoL and VO2max showed improvement over time in responders, compared with non-responders. With a median follow-up of 52 months, median response duration was not reached, and 3-year cumulative incidence of acute myeloid leukemia and overall survival (OS) was 14.5 and 70 %, respectively. Baseline transfusion dependence, International Prognostic Score System (IPSS), and Revised IPSS accurately predicted OS from treatment onset. Tolerance of darbepoetin was good. In conclusion, this regimen of darbepoetin every 2 weeks yielded high response rates and prolonged response duration. Objective improvement in exercise testing and in patient-reported QoL confirms the clinical relevance of anemia correction with erythropoiesis-stimulating agents.

Abstract
Details of the reproductive endocrinology of the dibbler, Parantechinus apicalis, an endangered member of the Family Dasyuridae, are presented from two geographically-separated populations, living either on the mainland or on islands in Jurien Bay, Western Australia. Plasma free cortisol in males measured in the island population during 1998/9 did not differ between the breeding and non-breeding season, but during the March rut in 2000, when males died after breeding, free cortisol levels were significantly raised. Post-mating mortality in dibbler males is facultative, rather than obligatory and the cortisol data implicate the same physiological sequelae described in other dasyurids. In females, a single annual oestrus was recorded during late summer to autumn in both populations with an onset earlier by 12 days in the mainland animals. Faecal steroids excreted as progesterone metabolites (PM) and oestradiol-17β were measured during the annual oestrous period and showed significantly higher PM concentrations in island animals. Oestradiol, although raised, was not different between the two populations. A profile of PM levels throughout gestation revealed a small peak at the time of ovulation, followed by slowly rising levels to peak 8 days before birth, indicating slow development of the corpora lutea. Using collective data, the presumptive day of ovulation could be identified, allowing the calculation of a presumptive gestation length of 45days in dibblers from mainland populations. This gestation length compares with that of a related species, Pseudantechinus macdonnellensis, reported at 45-55 days. A surprising finding is the significantly shorter gestation period of approximately 38 days in island animals compared with those from the mainland. This and other differences between reproductive parameters of island and mainland populations are discussed in the context of the 'island syndrome'.

Abstract
Melasma is a common disorder of hyperpigmentation that is present most commonly in reproductive age women with brown or black skin colors. The lesions of melasma are characteristically distributed in a symmetric manner on the sun-exposed areas of the face and neck. The precise pathogenesis of the disorder is unknown, but a number of etiologic agents have been implicated as its cause. These include ultraviolet radiation, hormonal alterations such as those evident during pregnancy, thyroid dysfunction, and phototoxic and anti-seizure drugs. The pathophysiology of melasma is believed to involve excess production of melanin or an increase in the number of melanocytes in the skin. This is confirmed by histological analysis of melasma, which shows an increased number of melanocytes along with an enhanced capability of these cells to produce melanin. Lack of an understanding of the precise pathogenesis of the condition has led to a large number of treatments for melasma. These therapies include hypopigmenting agents, chemical peels, lasers, and dermabrasion. Further investigations into this disorder may lead to more specific and effective treatments in the future.

Abstract
A 3-year-old girl with multifocal hepatoblastoma was referred to our clinic for living-donor liver transplantation, the patient's father being the donor. Pretransplant evaluation revealed that the father presented partial asymptomatic antithrombin (AT) deficiency, with no inherited AT deficiency found in the girl. The genetic testing showed an AT type IIb deficiency responsible for a defect in the heparin-binding region of AT which is less thrombogenic but more common than the other AT qualitative defects. Her mother was ABO incompatible. Despite the thrombophilia on the father's side, transplantation was successfully performed under replacement therapy with intravenous AT concentrate and low-molecular-weight heparin thromboprophylaxis given to both the recipient and the donor. No thrombotic complications occurred. In the posttransplantation course, acquired partial AT deficiency was detected in the recipient, who received adjuvant chemotherapy without thrombotic complications. This case report highlights the relevance of full thrombophilic work-up before liver transplantation from a living donor, while illustrating that the procedure can be successfully performed in the case of AT deficiency on the donor's side provided that appropriate AT supplementation and thromboprophylaxis are administered to both the recipient and the donor.

Abstract
We demonstrate a self-contained methodology for predicting conductance histograms of atomic and molecular junctions. Fast classical molecular-dynamics simulations are combined with accurate density functional theory calculations predicting both quantum transport properties and molecular-dynamics force field parameters. The methodology is confronted with experiments on atomic-sized indium nanojunctions. Beside conductance histograms the distribution of individual channel transmission eigenvalues is also determined by fitting the superconducting subgap features in the I-V curves. The remarkable agreement in the evolution of the channel transmissions demonstrates that the simulated ruptures are able to reproduce a realistic statistical ensemble of contact configurations, whereas simulations on selected ideal geometries show strong deviations from the experimental observations.
