Localisation Intravésicale d’une Broche d’ostéosynthèse (A Propos D’un Cas)

La variété de corps étrangers introduits dans l’appareil génito- urinaire défie l’imagination et peut confronter l’urologue aux difficultés de leur extraction. Si leur présence relève souvent d’une pratique douteuse d’origine psychiatrique, il faut noter la possibilité d’une migration à partir des espaces perivésicaux lors d’une chirurgie de voisinage ainsi qu’une introduction accidentelle durantune intervention transvésicale. Les symptômes du bas appareil urinaire, non spécifiques, sont les circonstances fortuites de découverte de corps étrangers intravésicaux. Bien que le pronostic vital ne soit pas engagé, l’extractionchirurgicale ou endoscopique s’avère nécessaire du fait de l’inflammation sévère associée aux dommages vésicaux secondaires à ce corps étranger.Nous rapportons le cas d’un jeune patient admis aux urgences chez qui on trouve une broche d’ostéosynthèse compliquée d’une lithiase située dans la vessie

Leiomyosarcome Du Cordon Spermatique

Introduction: Leiomyosarcoma of the spermatic cord is a rare tumor, develops from the mesenchymal tissues of the spermatic cord, epididymis and  testicular tunics. Its incidence is 0.05 to 0.1% and the occurrence in the testis is rare. In the literature, the testicular leiomyosarcoma (LST) is reported as sporadic cases or as a very limited series. In adults, most testicular sarcomas are the result of a sarcomatous transformation of germ cell tumors (GCT) especially teratomas and spermatocytic sarcomas.Observation: We report on a pure paratesticular leiomyosarcoma and we present the histological, therapeutic and prognostic aspects of this rare tumor

Le cancer du rein chez l’adulte. Etude rétrospective à propos de 155 cas

Objectif: Analyser les différents aspects épidémiologiques, cliniques, radiologiques, pathologiques et thérapeutiques du cancer du rein dans notre contexte. Patients et méthodes: Il s’agit d’une étude rétrospective à partir des dossiers des patients hospitalisés à notre service d’urologie pour tumeurs du rein entre 1990 et 2007. Sur les 155 dossiers consultés, 125 patients ont été traités chirurgicalement, et pour 30 patients, l’abstention a été justifiée par le stade évolué localement ou métastatique et/ou le mauvais état général. Les paramètres étudiés ont été : l’âge, la symptomatologie clinique, le bilan radiologique, le type d’intervention, les résultats anatomopathologiques et le stade histologique TNM. Tous les patients ont été revus avec un examen clinique, une échographie ou tomodensitométrie abdominale avec radiographie thoracique et une créatinémie. Résultats: Il s’agissait de 105 hommes et 50 femmes. L’âge moyen de découverte était de 60 ans (extrêmes : 18 et 85 ans). Le délai moyen entre l’apparition des symptômes et le diagnostic était d’environ 9 mois (extrêmes : 1 et 24 mois). L’hématurie était le signe révélateur le plus important noté chez 45,2% des cas. Le diagnostic a été basé sur le couple échographie – tomodensitométrie chez tous nos patients. La taille tumorale moyenne était de 10 cm (extrêmes 3 et 20 cm) lors du bilan initial. Le rein gauche était touché plus souvent que le rein droit (67% vs. 33%). Le bilan d’extension à distance était négatif chez 95 patients (61,3%), alors que 60 patients avaient des métastases viscérales et/ou ganglionnaires. Parmi ces derniers, 30 avaient un mauvais état général et/ou des métastases viscérales multiples ce qui a contre indiqué le geste opératoire. Les localisations métastatiques des 30 patients opérés étaient les suivantes: poumons (5 cas), ganglions (15 cas), os (2 cas), foie (8 cas). Plus de 80% des tumeurs étaient des carcinomes à cellules claires (carcinomes conventionnels). L’intervention a consisté à une néphrectomie totale élargie à ciel ouvert chez tous nos patients opérés. La médiane de suivi était de 62 mois (extrêmes: 6-72 mois). Trente patients ont été perdus de vue définitivement après l’intervention. Sur l’ensemble de la série, les taux respectifs de survie sans récidive à 3 ans et à 5 ans étaient de 78,4% et 47,2%. Conclusion: Le cancer du rein est une pathologie qui n’est pas rare. Sa symptomatologie est polymorphe. Le traitement de référence est la néphrectomie totale élargie. Les facteurs pronostiques les plus déterminants sont le stade (TNM) et le grade histologique de Fuhrman. Selon notre série, la néphrectomie élargie permet un taux de survie sans récidive supérieur à 85%, tous stades et types histologiques confondus.Mots clés: Cancer, rein, adulte

Hypertension Prevalence, Awareness, Treatment and Control, and Associated Factors: Results from a National Survey, Jordan

The study examined prevalence, awareness, treatment and control of hypertension (HTN), and associated factors and to evaluate the trend in hypertension between 2009 (period 2) and 1994–1998 (period 1). A national sample of 4117 adults aged 25 years and older was selected. Prevalence rate of HTN (SBP ≥ 140 or DBP ≥ 90 or on antihypertensive therapy) was 32.3% and was higher than the 29.4% prevalence rate reported in period 1. Prevalence rate was significantly higher among males, older age groups, least educated, obese, and diabetics than their counterparts. The rate of awareness among hypertensives was 56.1% and was higher than the 38.8% rate reported form period 1 data. Awareness was positively associated with age, smoking, and diabetes for both men and women, and with level of education and body mass index for men. Rate of treatment for HTN among aware patients was 63.3% and was significantly higher than the 52.8% rate reported in period1. Control rate of HTN among treated hypertensives was 39.6%; significantly higher than the 27.9% control rate in period 1. Control of HTN was positively associated with age but only for women. In conclusion, HTN is still on the rise in Jordan, and levels of awareness and control are below the optimal levels

Profiling Early Lung Immune Responses in the Mouse Model of Tuberculosis

Tuberculosis (TB) is caused by the intracellular bacteria Mycobacterium tuberculosis, and kills more than 1.5 million people every year worldwide. Immunity to TB is associated with the accumulation of IFNγ-producing T helper cell type 1 (Th1) in the lungs, activation of M.tuberculosis-infected macrophages and control of bacterial growth. However, very little is known regarding the early immune responses that mediate accumulation of activated Th1 cells in the M.tuberculosis-infected lungs. To define the induction of early immune mediators in the M.tuberculosis-infected lung, we performed mRNA profiling studies and characterized immune cells in M.tuberculosis-infected lungs at early stages of infection in the mouse model. Our data show that induction of mRNAs involved in the recognition of pathogens, expression of inflammatory cytokines, activation of APCs and generation of Th1 responses occurs between day 15 and day 21 post infection. The induction of these mRNAs coincides with cellular accumulation of Th1 cells and activation of myeloid cells in M.tuberculosis-infected lungs. Strikingly, we show the induction of mRNAs associated with Gr1+ cells, namely neutrophils and inflammatory monocytes, takes place on day 12 and coincides with cellular accumulation of Gr1+ cells in M.tuberculosis-infected lungs. Interestingly, in vivo depletion of Gr1+ neutrophils between days 10–15 results in decreased accumulation of Th1 cells on day 21 in M.tuberculosis-infected lungs without impacting overall protective outcomes. These data suggest that the recruitment of Gr1+ neutrophils is an early event that leads to production of chemokines that regulate the accumulation of Th1 cells in the M.tuberculosis-infected lungs

Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

This paper presents measurements of the $W^+ \rightarrow \mu^+\nu$ and $W^- \rightarrow \mu^-\nu$ cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino

Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks, 1990-2015: a systematic analysis for the Global Burden of Disease Study 2015

SummaryBackground The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context. Methods We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks from 1990 to 2015. This study included 388 risk-outcome pairs that met World Cancer Research Fund-defined criteria for convincing or probable evidence. We extracted relative risk and exposure estimates from randomised controlled trials, cohorts, pooled cohorts, household surveys, census data, satellite data, and other sources. We used statistical models to pool data, adjust for bias, and incorporate covariates. We developed a metric that allows comparisons of exposure across risk factors—the summary exposure value. Using the counterfactual scenario of theoretical minimum risk level, we estimated the portion of deaths and DALYs that could be attributed to a given risk. We decomposed trends in attributable burden into contributions from population growth, population age structure, risk exposure, and risk-deleted cause-specific DALY rates. We characterised risk exposure in relation to a Socio-demographic Index (SDI). Findings Between 1990 and 2015, global exposure to unsafe sanitation, household air pollution, childhood underweight, childhood stunting, and smoking each decreased by more than 25%. Global exposure for several occupational risks, high body-mass index (BMI), and drug use increased by more than 25% over the same period. All risks jointly evaluated in 2015 accounted for 57·8% (95% CI 56·6–58·8) of global deaths and 41·2% (39·8–42·8) of DALYs. In 2015, the ten largest contributors to global DALYs among Level 3 risks were high systolic blood pressure (211·8 million [192·7 million to 231·1 million] global DALYs), smoking (148·6 million [134·2 million to 163·1 million]), high fasting plasma glucose (143·1 million [125·1 million to 163·5 million]), high BMI (120·1 million [83·8 million to 158·4 million]), childhood undernutrition (113·3 million [103·9 million to 123·4 million]), ambient particulate matter (103·1 million [90·8 million to 115·1 million]), high total cholesterol (88·7 million [74·6 million to 105·7 million]), household air pollution (85·6 million [66·7 million to 106·1 million]), alcohol use (85·0 million [77·2 million to 93·0 million]), and diets high in sodium (83·0 million [49·3 million to 127·5 million]). From 1990 to 2015, attributable DALYs declined for micronutrient deficiencies, childhood undernutrition, unsafe sanitation and water, and household air pollution; reductions in risk-deleted DALY rates rather than reductions in exposure drove these declines. Rising exposure contributed to notable increases in attributable DALYs from high BMI, high fasting plasma glucose, occupational carcinogens, and drug use. Environmental risks and childhood undernutrition declined steadily with SDI; low physical activity, high BMI, and high fasting plasma glucose increased with SDI. In 119 countries, metabolic risks, such as high BMI and fasting plasma glucose, contributed the most attributable DALYs in 2015. Regionally, smoking still ranked among the leading five risk factors for attributable DALYs in 109 countries; childhood underweight and unsafe sex remained primary drivers of early death and disability in much of sub-Saharan Africa. Interpretation Declines in some key environmental risks have contributed to declines in critical infectious diseases. Some risks appear to be invariant to SDI. Increasing risks, including high BMI, high fasting plasma glucose, drug use, and some occupational exposures, contribute to rising burden from some conditions, but also provide opportunities for intervention. Some highly preventable risks, such as smoking, remain major causes of attributable DALYs, even as exposure is declining. Public policy makers need to pay attention to the risks that are increasingly major contributors to global burden. Funding Bill & Melinda Gates Foundation
