The embedded blocks were then extracted by means of a new extracting method and the eluates were measured. We also selected five toxicological cases of heroin-related fatalities that were examined 20\u00a0years ago, collected the toxicological result documents of the analysis that were carried out at the time and then processed the corresponding FFPE liver samples that were stored in the archives.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>We managed to isolate heroine-related metabolites from 20-year-old paraffin-embedded blocks and calculated ratios to evaluate the performance of our new extraction.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>According to\u00a0our study, it is feasible to carry out a toxicological examination on old histological samples and, therefore, this matrix can be considered as a new alternative specimen for chemical-analytical evaluations of past cases or when fresh samples are not available anymore. The new extractive method was evaluated as efficient in treating these complex, paraffin-embedded samples. It was surprising that the target compounds could be quantitated from FFPE bocks created as long as 20\u00a0years ago.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s11419-022-00614-0","type":"journal-article","created":{"date-parts":[[2022,3,14]],"date-time":"2022-03-14T14:04:07Z","timestamp":1647266647000},"page":"302-311","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Histological paraffin-embedded block: a good alternative specimen to detect the use of opiates at least 20\u00a0years ago"],"prefix":"10.1007","volume":"40","author":[{"given":"Domenico","family":"Di Candia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4240-4121","authenticated-orcid":false,"given":"Michele","family":"Boracchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guendalina","family":"Gentile","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaia","family":"Giordano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Riccardo","family":"Zoja","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,3,14]]},"reference":[{"key":"614_CR1","doi-asserted-by":"publisher","first-page":"363","DOI":"10.3109\/15376516.2010.497976","volume":"20","author":"RJ Dinis-Oliveira","year":"2010","unstructured":"Dinis-Oliveira RJ, Carvalho F, Duarte JA, Remi\u00e3o F, Marques A, Santos A, Magalh\u00e3es T (2010) Collection of biological samples in forensic toxicology.
