    Toluene and xylene are aromatic hydrocarbons commonly used as an industrial solvent for the manufacturing of pharmaceuticals, paints, and chemicals. The Occupational Safety and Health Administration has determined that toluene levels of 2000 parts per million (ppm) are considered dangerous to life and health. Several studies have examined the absorption of toluene and xylene following inhalation and oral ingestion in humans. Volatile organic compounds that are absorbed into the blood are distributed throughout the body; in particular, distribution of absorbed toluene and xylene in humans and rodents is characterized by preferential uptake in well-perfused and lipophil tissues such as the brain, liver, lungs, and body fat and also in central nervous system. The available studies indicate that xylenes are rapidly absorbed independently from the kind of exposition. We illustrate a fatal case of self-poisoning by ingestion of varnishes diluting solvents, reporting the identification and quantification of volatile organic compounds (toluene, o-m-p xylene) from human biologic liquids and viscera samples using the Solid-Phase Microextraction- Headspace-Gas Chromatography/Mass Spectrometry to toxicological analysis, and the histopathological findings evaluated in liver, kidney, and lungs.

    Managing cancer patients with acute venous thromboembolism: exploring safe alternatives to hospitalisation

    No full text
    Acute venous thromboembolism (VTE) is a common and potentially fatal complication that frequently occurs in cancer patients. Few data are currently available about the optimal management of this category of high-risk patients. In clinical practice, physicians have to deal with many problems related to cancer patients with acute VTE. For instance, cancer patients with deep vein thrombosis (DVT) are frequently admitted to the hospital since their high rate of recurrent thrombotic events and/or bleeding-related therapy; however, most of them would prefer alternatives to prolonged hospitalisation. Then, it is not clearly whether data coming from a non-cancer population (such as that regarding the use of D-dimer test and/or pre-test clinical probability [PCP]), can be reliable applied in cancer patients. Finally, scanty information is present on the feasibility of the "home-treatment program" for DVT in this category of high-risk patients. In our review we present data on a population of cancer patients evaluated at the Emergency Care in whom we have evaluated: 1) the diagnostic accuracy of PCP and D-dimer test; 2) the safety and efficacy of low molecular weight heparins (LMWH) as "protective anticoagulation" in case of deferred imaging for VTE and 3) the safety and efficacy of home treatment

    Multicenter retrospective analysis of clinical outcome of adult patients with mixed-phenotype acute leukemia treated with acute myeloid leukemia-like or acute lymphoblastic leukemia-like chemotherapy and impact of allogeneic stem cell transplantation: a Campus ALL study

    : Mixed-phenotype acute leukemia (MPAL) is a rare disease. Treatment is often similar to that of acute lymphoblastic leukemia (ALL), but the outcome in adults and the role of allogeneic stem cell transplantation (AlloSCT) are not well defined. We report on 77 adult patients diagnosed with MPAL over the last 10 years and treated with a curative intent. Median age was 49 years; 7.6% of cases had a BCR::ABL1 rearrangement. Thirty patients (39%) were treated with an acute myeloid leukemia (AML)-like induction and 47 (61%) with an ALL-like scheme. The complete remission (CR) rate was 67.6% and an ALL-like therapy was associated with a better CR rate (P = 0.048). The median OS was 41.9 months; age ≤ 60 years was associated with a better OS (67 vs 26 months, P = 0.014). An AlloSCT was performed in 50 patients (65%). The 5-year OS of transplanted patients was 54%. The OS post-AlloSCT was better in patients who were minimal residual disease (MRD)-negative prior to transplant (75.8% vs 45.2%, P = 0.06). This study shows that MPAL patients respond better to an ALL-like induction therapy; that consolidation therapy should include, whenever possible, an AlloSCT and that MRD negativity should be a primary endpoint of treatment
