Documented cases of sodium nitrite toxicity are almost exclusively caused by accidental ingestion; however, self-poisoning with sodium nitrite represents an increasing trend in nitrate-related deaths. This systematic review summarizes the most crucial evidence regarding the fatal toxicity of sodium nitrite. It identifies gaps and differences in the diagnostic forensic approaches and the detection methods of sodium nitrite intoxication. A total of eleven research articles were selected for qualitative and quantitative data. Most of the studies (6/11) were case reports. Fifty-three cases of fatal intoxication with sodium nitrite were chosen for the review. More research is required to develop cost-effective techniques and uniform cutoffs for blood nitrite and nitrate levels in the event of deadly sodium nitrite poisoning. There is still a lack of critical information on other matrices and the impact of time since death on toxicological results in such situations. The available evidence provides useful recommendations for forensic pathologists and health practitioners engaged in instances of sodium nitrite poisoning or death. The data should also set off alarm bells in the public health system, in prosecutor’s offices, and for policymakers so that they may undertake preventative measures to stop and restrict the unregulated market for these substances.

Exhumations are performed in accordance with a court order and are crucial instruments in the investigation of death allegations. When a death is thought to be the result of drug misuse, pharmaceutical overdose, or pesticide poisoning, this process may be used on human remains. However, after a protracted postmortem interval (PMI), it might be difficult to detect the cause of death by looking at an exhumed corpse. The following case report reveals problems associated with postmortem drug concentration changes following exhumation more than two years after death. A 31-year-old man was found dead in a prison cell. Onan inspection of the place, two blister packs, one with a tablet and the other empty, were taken and kept by the police officers. The evening before, the deceased would have taken cetirizine and food supplements consisting of carnitine–creatine tablets. No relevant autopsy findings have been observed. The toxicological analysis was performed by gas chromatography coupled to mass spectrometry and was negative for substances of abuse. Proteomic analysis was positive for creatine detection and negative for other drugs (clarithromycin, fenofibrate, and cetirizine). The presented case shows the methods, the findings, and the limitations of toxicological analysis in an exhumation case with a long postmortem interval (PMI).

The maltreatment and torture of prisoners constitute a global problem. Methods of maltreatment are classified as the psychological and the physical, and physical methods inevitably lead to psychological sequelae. Our review offers an analysis from the medico-legal perspective of the literature on the torture and physical and sexual abuse experienced by prisoners and their psychological sequelae and aims to investigate the medico-legal issues of investigating maltreatment in prison so as to suggest methodologies and updated approaches for dealing with such cases in a forensic context. We performed a comprehensive literature search of peer-reviewed publications (articles and reviews), research reports, case studies, books, service models, protocols, and institutional documents available online using key electronic databases (Scopus, PubMed) and search engines (Google Scholar) with the following keywords: physical violence, psychological violence, torture, maltreatment, physical abuse, psychological abuse AND prison OR prisoner OR jail OR custody. In the medical literature, most of the publications on torture are based on retrospective studies of torture among survivors and often refer to asylum seekers. Forensic evaluation is crucial for assessing the determinant elements of torture and maltreatment. A multidisciplinary approach and standardized and updated methodologies are needed to support policymakers, national institutions, and public health system initiatives in this field.
