The culmination of the process of creating the Institutes of Legal Medicine (IML) with the commissioning of the IML of Madrid in 2020 homogenizes the competences of forensic medicine throughout the country. Recent legislative reforms in specialized medical training, expand their responsibilities to cover, in addition to the expert function, a stronger role in teaching and research. The design and implementation of quality systems must become a priority for IMLs in order to guarantee their effectiveness and efficiency by providing accurate, reliable and timely results. This article provides a detailed review of the procedure to be followed to design a quality strategy in Forensic Pathology Services.

Introduction

Sudden unexpected deaths in infancy (SUDI) represents a serious public health problem. The objective of this work is to analyze its epidemiological and clinical-pathological characteristics.

Method

Retrospective population study of SUDI in Bizkaia between 1991–2020. Data from the Mortality Registry and Forensic Pathology Service were examined.

Results

1,109 deaths in children under one year were recorded. A forensic autopsy was performed in 107: 61 cases of sudden infant death syndrome (SIDS) and 23 SUDI of explained cause. In other 10 cases SIDS was coded as cause of death without forensic autopsy. The incidence of SIDS was 0.26/1000/year and decreased from 0.74 (1991–1995 five-year period) to 0.07 (2011–15 and 2016–20 periods). The percentage of SIDS in relation to total mortality decreased from 11.2 to 2.5%. In SIDS, category IB from San Diego (67%) and infants between 1 and 4 months (63%) predominated. An “unsafe sleep environment” was detected in 6 SIDS. 56.5% of the explained SUDI were infectious. Of the 84 autopsied SUDI cases, 70% had no pre-existing disease and 15% were premature and/or low birth weight infants. In 32% there were prodromal symptoms, mainly respiratory tract infection. Microscopic findings suggestive of respiratory infection were diagnosed in 10 SIDS.

Conclusions

The incidence of SIDS in Bizkaia is low and has decreased notably in the last 30 years. Prodromal symptoms and histopathological signs suggestive of infection are relatively common. Forensic studies provide relevant data, although prospective multidisciplinary and multicenter research would be desirable.

Uterine arteriovenous malformation (UAMM) for some authors, considered an arteriovenous fistula, represents between 1% and 2% of genital and intraperitoneal hemorrhage as a result of spontaneous or provoked vascular rupture after a surgical intervention.

We present a case of maternal death that occurred during a walk on a slope, presenting metrorrhagia and fainting with a fatal outcome. The medico-legal autopsy showed a pregnancy uterus with myometrial hemorrhage and multiple blood clots, diagnosed pathologically as a uterine arteriovenous malformation.

Maternal death is a multifactorial public health problem in underdeveloped countries. Uterine arteriovenous malformation is a rare cause, however some authors consider it underdiagnosed; reported cases have increased in recent years and in developing countries it can be lethal.

A case of suicide by nitrites ingestion is reported: a young woman was found death into a car with various objetcs around her, such as a white powder bag labelled as «sodium nitrite» and pills of lorazepam, acetaminophen and metoclopramide. The autopsy revealed signs compatible with methemoglobinemia and samples of blood, vitreous and gastric content were submitted to the Drugs Service of the National Institute of Toxicology and Forensic Sciences in Madrid, as well as the powder bag, the pills and other objects. The white powder was identified as sodium nitrite, and nitrites concentrations similar to other fatalities were detected in biological samples. The methemoglobin level was 80%. The existence of websites where suicide with nitrites and metoclopramide is described step-by-step, joined to the increasement of reports about these fatalities, alert us to a possible trend.

The regulation of euthanasia has been the subject of debate for years, from the fields of Medicine, Law and Bioethics, and therefore of Legal Medicine, in which these three disciplines converge. In the last thirty years we have experienced a process of decriminalization and regulation in different countries of the world. Currently euthanasia and/or assisted suicide are regulated in 7 countries: Holland, Belgium, Luxembourg, Canada, Colombia, New Zealand and Spain, as well as in 11 US states: Oregon, Washington, Montana, Vermont, California, Colorado, Hawaii, Maine, New Jersey, New Mexico and the Federal District of Columbia / Washington D.C, and in 2 states of Australia: State of Victoria and Western Australia. In this review work we carry out a study on the most important aspects of the new law of the regulation of euthanasia in Spain compared to the rest of the countries in which they also have the regularization of euthanasia and / or assisted suicide.

DNA databases for criminal investigation purposes, constitute a tool of indisputable utility in the investigation of criminal acts.

In the countries of Latin America there is a progressive advance in the implementation of databases for forensic use. The existing legislation is limited, and it is also heterogeneous both with respect to the crimes included and the procedural situation of the individuals whose DNA is subject to registration. Most of them do not require the accreditation of the forensic laboratories under the ISO 17025 standard. Existing DNA databases currently lack a standard communication regime.

The establishment of a system of consultation and exchange of genetic data in support of national criminal systems and the prosecution of crimes at the international level, demands cooperation agreements, for which, those implemented in the European Union since 1992, perfected with the decision of Prüm, constitute a valuable reference.
