Not responsible self-medication refers to drug use in high doses without rational indication and often associated with alcohol abuse. It can lead to liver damage and drug interactions, and may cause liver failure.
To warn about how the practice of self-medication can be responsible for acute liver failure.
Were used the Medline via PubMed, Cochrane Library, SciELO and Lilacs, and additional information on institutional sites of interest crossing the headings acute liver failure [tiab] AND acetaminophen [tiab]; self-medication [tiab] AND acetaminophen [tiab]; acute liver failure [tiab] AND dietary supplements [tiab]; self-medication [tiab] AND liver failure [tiab] and self-medication [tiab] AND green tea [tiab]. In Lilacs and SciELO used the descriptor self medication in Portuguese and Spanish. From total surveyed were selected 27 articles and five sites specifically related to the purpose of this review.
Legislation and supervision disabled and information inaccessible to people, favors the emergence of cases of liver failure drug in many countries. In the list of released drugs that deserve more attention and care, are some herbal medicines used for the purpose of weight loss, and acetaminophen. It is recommended that institutes of health intensify supervision and better orient their populations on drug seemingly harmless, limiting the sale of products or requiring a prescription for release them.
Some studies have suggested that preoperative chemotherapy for hepatic colorectal metastases may cause hepatic injury and increase perioperative morbidity and mortality.
To evaluate the prevalence of hepatic steatosis in patients undergoing preoperative chemotherapy for metastatic colorectal cancer.
Observational retrospective cohort study in which 166 patients underwent 185 hepatectomies for metastatic colorectal cancer with or without associated preoperative chemotherapy from 2004 to 2011. The data were obtained from a review of the medical records and an analysis of the anatomopathological report on the non-tumor portion of the surgical specimen. The study sample was divided into two groups: those who were exposed and those who were unexposed to chemotherapy.
From the hepatectomies, 136 cases (73.5%) underwent preoperative chemotherapy, with most (62.5%) using a regimen of 5-fluorouracil + leucovorin. A 40% greater risk of cell damage was detected in 62% of the exposed group. The predominant histological pattern of the cell damage was steatosis, which was detected in 51% of the exposed cases. Exposure to chemotherapy increased the risk of steatosis by 2.2 fold. However, when the risk factors were controlled, only the presence of risk of hepatopathy was associated with steatosis, with a relative risk of 4 (2.7-5.9).
Patients exposed to chemotherapy have 2.2 times the risk of developing hepatic steatosis, and its occurrence is associated with the presence of predisposing factors such as diabetes mellitus and hepatopathy.
