Indication pour une analyse de poussi\u00e8re de poumon :<\/h2>\n

En cas de suspicion de maladie pulmonaire d’origine professionnelle due aux ant\u00e9c\u00e9dents de travail et \/ ou \u00e0 la pr\u00e9sentation clinico-radiologique, l’analyse des poussi\u00e8res pulmonaires est utile pour estimer le type et l’\u00e9tendue de l’exposition aux poussi\u00e8res. Les r\u00e9sultats doivent \u00eatre en corr\u00e9lation avec les changements histologiques. M\u00eame chez les patients pr\u00e9sentant un m\u00e9soth\u00e9liome pleural malin mais avec des ant\u00e9c\u00e9dents professionnels divergents, une analyse compl\u00e8te de la poussi\u00e8re pulmonaire avec d\u00e9termination quantitative de l’amiante sur du tissu pulmonaire exempt de tumeur est recommand\u00e9e.<\/p>\n

Mat\u00e9riaux d’\u00e9chantillon appropri\u00e9 pour une analyse de poussi\u00e8re de poumon :<\/h2>\n

Pour une analyse fiable des poussi\u00e8res, un tissu pulmonaire p\u00e9riph\u00e9rique fix\u00e9 au formol et sans tumeur est requis. Les pi\u00e8ces id\u00e9ales comprennent 3 morceaux d’environ 2 cm3 pr\u00e9lev\u00e9s \u00e0 3 endroits diff\u00e9rents (1 x apex du lobe sup\u00e9rieur, 1 x apex du lobe inf\u00e9rieur et 1 x base du lobe inf\u00e9rieur). Si aucun tissu pulmonaire fix\u00e9 au formol n’est disponible, des blocs de paraffine fabriqu\u00e9s \u00e0 partir de celui-ci peuvent \u00e9galement \u00eatre utilis\u00e9s pour l’analyse. Cependant, il convient de noter que les blocs sont dissouts pour analyse et ne sont donc pas renvoy\u00e9s \u00e0 l’exp\u00e9diteur.<\/p>\n

Des analyses de poussi\u00e8res pulmonaires peuvent \u00e9galement \u00eatre effectu\u00e9es sur le liquide de lavage bronchoalv\u00e9olaire. Ceci n\u00e9cessite au moins 20 ml, si possible 30 ml de liquide de lavage non filtr\u00e9 avec au moins 10 ml de NaOCl (12%) ajout\u00e9.<\/p>\n<\/div><\/div>

Proc\u00e9dure d’analyse de la poussi\u00e8re pulmonaire :<\/h2>\n

Une premi\u00e8re \u00e9valuation histologique d\u00e9cide si une analyse de poussi\u00e8re est faisable \/ utile. Le pathologue de l\u2019h\u00f4pital universitaire de Zurich envoie alors le mat\u00e9riel \u00e0 la silag avec la demande d\u2019analyse. Les \u00e9chantillons de tissus sont pr\u00e9par\u00e9s par la silag pour le comptage FB respectivement de l’analyse morphologique et chimique des fibres au microscope \u00e9lectronique \u00e0 transmission (TEM \/ EDX). La silag fait les analyses et transmet les r\u00e9sultats en forme d\u2019un rapport d\u2019analyses au pathologue pulmonaire responsable. Le pathologue r\u00e9unit les r\u00e9sultats histologique et d\u2019analyses dans un rapport int\u00e9gral. Les r\u00e9sultats finals sont disponibles dans un d\u00e9lai de 2 \u00e0 4 semaines environ, en fonction du volume des commandes et de la planification des analyses.<\/p>\n

Rapport final :<\/h2>\n

Les examens histologiques sont r\u00e9sum\u00e9s avec les r\u00e9sultats des analyses FB et TEM \/ EDX dans un rapport \/ rapport int\u00e9gratif. Ce rapport est envoy\u00e9 au m\u00e9decin envoyeur. Une copie, comprenant les r\u00e9sultats des analyses FB et TEM \/ EDX, sera envoy\u00e9e \u00e0 l’Institut de pathologie qui a mis le tissu \u00e0 disposition.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"Examen pulmonaire de la poussi\u00e8re Silicose Asbestose Poumon en carbure Indication pour une analyse de poussi\u00e8re de poumon : En cas de suspicion de maladie pulmonaire d’origine professionnelle due aux ant\u00e9c\u00e9dents de travail et \/ ou \u00e0 la pr\u00e9sentation clinico-radiologique, l’analyse des poussi\u00e8res pulmonaires est utile pour estimer le type et l’\u00e9tendue de l’exposition aux...","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-150","page","type-page","status-publish","hentry"],"yoast_head":"\nExamen pulmonaire de la poussi\u00e8re -
