    Objectif : La surditĂ© professionnelle pose encore des problĂšmes de reconnaissance et d’indemnisation en Tunisie. L’objectif de notre Ă©tude est d’analyser les conditions de reconnaissance et d’indemnisation de la surditĂ© professionnelle auprĂšs des travailleurs d’une industrie automobile.MatĂ©riel et mĂ©thodes : Nous avons menĂ© une Ă©tude descriptive rĂ©trospective qui a portĂ© sur les salariĂ©s de la SociĂ©tĂ© Tunisienne d’Industrie Automobile (STIA) victimes de surditĂ© professionnelle reconnue par la Commission MĂ©dicale du centre sur une pĂ©riode de cinq ans (2003 Ă  2007).RĂ©sultats : Un total de 81 dossiers de surditĂ© professionnelle reconnue a Ă©tĂ© colligĂ© durant la pĂ©riode d’étude. Notre population Ă©tait constituĂ©e par une main d’oeuvre masculine qualifiĂ©e (50,6%) et non qualifiĂ©e (38,3%) ayant une anciennetĂ© moyenne dans le poste bruyant de 28,7 ± 6,8 ans. Le niveau moyen d’exposition professionnelle au bruit Ă©tait de 90,7 ± 3,9dB(A). Il Ă©tait plus Ă©levĂ© dans les ateliers de presse [92,4dB(A)], de tĂŽlerie [91,6 dB(A)] et de peinture [90 dB(A)]. La perte auditive moyenne (PAM) sur la meilleure oreille Ă©tait de 65,7 ± 17,4dB. Les potentiels Ă©voquĂ©s auditifs ont Ă©tĂ© pratiquĂ©s chez 66 patients (81,5%) et ont confirmĂ© le diagnostic de surditĂ© de perception dans 64 cas et d’une surditĂ© mixte dans les 2 autres cas. L’audiomĂ©trie tonale avec prothĂšse auditive a Ă©tĂ© pratiquĂ©e dans 71,6% des cas et a relevĂ© une amĂ©lioration estimĂ©e nette chez 81% des patients. Le taux moyen de l’incapacitĂ©permanente partielle Ă©tait de 21,5 ± 6,8% avec des extrĂȘmes allant de 8 et 51%. La majoritĂ© des salariĂ©s (92,6%) avaient un taux d’IPP entre 15 et 35%. La PAM > 60 dB a Ă©tĂ© statistiquement corrĂ©lĂ©e avec la catĂ©gorie professionnelle (p=0,017) et l’anciennetĂ© au travail (p=0,039).Conclusion : La rĂ©paration de la surditĂ© professionnelle prĂ©sente encore des limites et des imperfections liĂ©es aux critĂšres de reconnaissances qui doivent ĂȘtre rĂ©visĂ©es.Mots-clĂ©s : SurditĂ© professionnelle, Bruit, Industrie automobile, RĂ©paration

    <p>Abstract</p> <p>Background</p> <p>In Tunisia, country of intermediate endemicity for Hepatitis B virus (HBV) infection, most molecular studies on the virus have been carried out in the North of the country and little is known about other regions. The aim of this study was to determine HBV genotype and subgenotypes in Central-East Tunisia. A total of 217 HBs antigen positive patients were enrolled and determination of genotype was investigated in 130 patients with detectable HBV DNA. HBV genotyping methods were: PCR-RFLP on the pre-S region, a PCR using type-specific primers in the S region (TSP-PCR) and partial sequencing in the pre-S region.</p> <p>Results</p> <p>Three genotypes (D, B and A) were detected by the PCR-RFLP method and two (D and A) with the TSP-PCR method, the concordance between the two methods was 93%. Sequencing and phylogenetic analysis of 32 strains, retrieved the same genotype (D and A) for samples with concordant results and genotype D for samples with discordant results. The sequences of discordant genotypes had a restriction site in the pre-S gene which led to erroneous result by the PCR-RFLP method. Thus, prevalence of genotype D and A was 96% and 4%, respectively. Phylogenetic analysis showed the predominance of two subgenotypes D1 (55%) and D7 (41%). Only one strain clustered with D3 subgenotype (3%).</p> <p>Conclusions</p> <p>Predominance of subgenotype D7 appears to occur in northern regions of Africa with transition to subgenotype D1 in the East of the continent. HBV genetic variability may lead to wrong results in rapid genotyping methods and sequence analysis is needed to clarify atypical results.</p

    Awareness of cognitive decline trajectories in asymptomatic individuals at risk for AD

    Background: Lack of awareness of cognitive decline (ACD) is common in late-stage Alzheimer’s disease (AD). Recent studies showed that ACD can also be reduced in the early stages. Methods: We described different trends of evolution of ACD over 3 years in a cohort of memory-complainers and their association to amyloid burden and brain metabolism. We studied the impact of ACD at baseline on cognitive scores’ evolution and the association between longitudinal changes in ACD and in cognitive score. Results: 76.8% of subjects constantly had an accurate ACD (reference class). 18.95% showed a steadily heightened ACD and were comparable to those with accurate ACD in terms of demographic characteristics and AD biomarkers. 4.25% constantly showed low ACD, had significantly higher amyloid burden than the reference class, and were mostly men. We found no overall effect of baseline ACD on cognitive scores’ evolution and no association between longitudinal changes in ACD and in cognitive scores. Conclusions: ACD begins to decrease during the preclinical phase in a group of individuals, who are of great interest and need to be further characterized. Trial registration: The present study was conducted as part of the INSIGHT-PreAD study. The identification number of INSIGHT-PreAD study (ID-RCB) is 2012-A01731-42
