    peer reviewedLe blĂ©pharochalasis est une affection rare caractĂ©risĂ©e par des poussĂ©es oedĂ©mateuses des paupiĂšres aboutissant Ă  une altĂ©ration de leur structure fine et principalement Ă  un relĂąchement cutanĂ©. Il est le plus souvent bilatĂ©ral et atteint prĂ©fĂ©rentiellement les paupiĂšres supĂ©rieures. Nous rapportons l’observation d’une jeune fille de 11 ans, qui prĂ©sente un blĂ©pharochalasis qui s’est installĂ© 3 mois aprĂšs des Ă©pisodes successifs pratiquement subintrants d’ƓdĂšme palpĂ©bral. Le diagnostic a Ă©tĂ© Ă©toffĂ© par un examen histologique qui a montrĂ© une absence quasi totale de fibre Ă©lastique. Le blĂ©pharochalasis survient habituellement chez le sujet jeune. Deux formes cliniques sont classiquement dĂ©crites : la forme hypertrophique et la forme atrophique, observĂ©e chez notre patiente. L’atrophie des paupiĂšres s’installe progressivement sur plusieurs annĂ©es suite Ă  des poussĂ©es ƓdĂšmateuses qui durent quelques jours et qui surviennent 3 Ă  4 fois par an

    The physical demands of modern basketball were assessed by investigating 38 elite under‐19‐year‐old basketball players during competition. Computerised time–motion analyses were performed on 18 players of various positions. Heart rate was recorded continuously for all subjects. Blood was sampled before the start of each match, at half time and at full time to determine lactate concentration. Players spent 8.8% (1%), 5.3% (0.8%) and 2.1% (0.3%) of live time in high “specific movements”, sprinting and jumping, respectively. Centres spent significantly lower live time competing in high‐intensity activities than guards (14.7% (1%) v 17.1% (1.2%); p<0.01) and forwards (16.6% (0.8%); p<0.05). The mean (SD) heart rate during total time was 171 (4) beats/min, with a significant difference (p<0.01) between guards and centres. Mean (SD) plasma lactate concentration was 5.49 (1.24) mmol/l, with concentrations at half time (6.05 (1.27) mmol/l) being significantly (p<0.001) higher than those at full time (4.94 (1.46) mmol/l). The changes to the rules of basketball have slightly increased the cardiac efforts involved during competition. The game intensity may differ according to the playing position, being greatest in guards

    International audienceOBJECTIVES: To detect the presence of Toscana virus (TOSV) circulation in Tunisia and to study its role in viral meningo-encephalitis.PATIENTS AND METHODS: A total of 315 (167 sera and 178 cerobrospinal fluid [CSF]) samples was investigated. These samples are colleted from Tunisian patients with neurological diseases during the period between January 2003 and December 2009. All samples were tested negative for enterovirus, Herpes Simplex virus and West Nile virus. Detection for IgM and IgG specific to TOSV was done by ELISA tests.RESULTS: Specific IgM for TOSV were detected in 10 % of patients with neurological diseases (31 cases). These recent infections were distributed throughout the study period and predominated during summer and automn. Patients were originated, in the majority from the coastal region. IgG were isolated in 22 cases (7 %) corresponding to previous infection.CONCLUSION: This is the first report of TOSV circulating in Tunisia and its frequent implication in neurological diseases. These results incited to include TOSV as one of the viral etiologies to target in the diagnosis of viral meningitis and encephalitis in the country.But de l’étude : Rechercher les tĂ©moins de l’éventuelle prĂ©sence du virus Toscana (TOSV) en Tunisie et Ă©tudier son implication dans les infections neuromĂ©ningĂ©es dans le pays.Patients et mĂ©thodes : Au total, 167 prĂ©lĂšvements de sĂ©rums et 178 LCR collectĂ©s chez 315 patients, hospitalisĂ©s pour mĂ©ningite ou mĂ©ningo-encĂ©phalite virale, ont Ă©tĂ© investiguĂ©s. Ces prĂ©lĂšvements ont Ă©tĂ© collectĂ©s durant la pĂ©riode allant de janvier 2003 Ă  dĂ©cembre 2009 et ont Ă©tĂ© prĂ©alablement testĂ©s nĂ©gatifs vis-Ă -vis des entĂ©rovirus, virus Herpes Simplex de type 1 et virus West Nile. La recherche des IgM et IgG spĂ©cifiques du TOSV a Ă©tĂ© faite par Elisa indirecte.RĂ©sultats : Dix pour cent (n = 31) de ces prĂ©lĂšvements se sont rĂ©vĂ©lĂ©s positifs en IgM anti-TOSV ; ces cas sont rĂ©partis de façon homogĂšne sur toute la pĂ©riode Ă©tudiĂ©e. Une infection ancienne a Ă©tĂ© dĂ©tectĂ©e dans 7 % des cas (n = 22). L’infection neuromĂ©ningĂ©e Ă  TOSV est plus frĂ©quente chez l’homme (20/11), en pĂ©riode estivo-automnale et en zone cĂŽtiĂšre.Conclusion : Il s’agit lĂ  d’une premiĂšre Ă©tude rapportant la circulation du TOSV en Tunisie et son rĂŽle non nĂ©gligeable dans les infections neuromĂ©ningĂ©es. Ces rĂ©sultats nous incitent Ă  une surveillance rĂ©guliĂšre avec recherche systĂ©matique d’une infection Ă  TOSV devant toute atteinte neurologique. Il serait mĂȘme intĂ©ressant de gĂ©nĂ©raliser la recherche du TOSV Ă  d’autres tableaux cliniques oĂč il a Ă©tĂ© Ă©galement impliquĂ© comme le syndrome fĂ©brile aigu ou le syndrome grippal type « grippe d’étĂ© »
