Unidentified human remains discovered within Polish territory: Traces of the difficult history of the twentieth century.

Poland, due to its geographical location, has been a place where the interests of neighbouring countries have converged. As a result, Polish territory has been the site of hostilities, totalitarian terror, and acts of genocide. Following the end of World War II, Poland became part of the so-called Eastern Bloc. A movement known as the anti-communist underground arose within Polish territory with the aim of conducting partisan warfare and political and propaganda activities against the occupiers. Partisans were victims of campaigns of liquidation; they lost their lives during interrogations, died in prisons, were sentenced to death by Polish courts, and were subsequently buried at unknown sites throughout the country. In connection with war and post-war events within Polish territory, the remains of victims of both World War II and post-war political repressions are being found to this day. In addition, remains derived from historical populations are being discovered as well as present-day remains belonging to missing persons or victims of criminal offences. A portion of the remains resulting from military operations and the post-war history of Poland are discovered by chance, but discovery of the burial sites of victims of communist crimes is often preceded by many years of research. International agreements and Polish legal regulations make it possible to search for victims of armed conflicts of various nationalities within the country. The process of identifying victims of armed conflicts, political terror and genocide can be carried out thanks to routine procedures for handling unidentified remains. Given the diversity (various historical periods, various nationalities) of the discovered remains, the elaborated procedures enable their dignified burial.

[Skull fracture or accessory suture in a child?]. / Schädelfraktur oder akzessorische Sutur bei einem Kind?

Differentiation between accessory sutures and fractures in the skull of an infant can be difficult. Apart from the regular sutures there is a multitude of variations that may be mistaken for a fracture line. Such variations include for instance the intraparietal suture between the two ossification centers of the parietal bone or the mendosal suture between the supraoccipital and interparietal bone of the occipital squama. The presented case refers to an approximately 20-month-old female child. During autopsy, a discontinuity in the right paramedian posterior cranial fossa parallel to the internal occipital crest with connection to the foramen magnum was observed. The macroscopic findings suggested a fracture line because of its course. However, neither a hemorrhage in the soft tissue nor callus formation was discernible. The discontinuity was preserved with the adjacent parts of the occipital bone for further histological examination. In the report of a cranial CT, which was carried out five days before the child's death, an accessory suture paramedially in the right posterior cranial fossa was described. When the clinical CT records were re-evaluated, a similar discontinuity at the corresponding position on the other side was detected, though of noticeably shorter length. Additionally, the preserved occipital bone fragment including the discontinuity was histologically processed. In the radiological literature, precise (radiological) criteria for differential diagnosis are indicated. A zigzag pattern with sclerotic borders and a bilateral and fairly symmetric occurrence indicate a suture, whereas a sharp lucency with non-sclerotic edges and a unilateral occurrence indicate a fracture. Taking all the findings into account, the depicted discontinuity was regarded as an accessory suture. This case demonstrates that differentiation between a fracture and an accessory suture may be difficult in the autopsy of a child and underlines the importance of a postmortem CT examination.

[Reconstructive investigations and identification measures in unknown soldiers of the Second World War]. / Rekonstruktive Untersuchungen und Identifikationsmassnahmen bei unbekannten Soldaten aus dem Zweiten Weltkrieg.

The article reports on the exhumation and identification of unknown soldiers from the Second World War. With the help of medicolegal investigation and reconstruction methods an American pilot presumably murdered by a shot to the head (lynch law) and an interned Italian soldier could be identified after about 70 years and brought back home.

La identificación genética como herramienta en la investigación de adopciones irregulares y sustracción de recién nacidos en España: experiencia del Instituto Nacional de Toxicología y Ciencias Forenses (Departamento de Barcelona) / Genetic identification as a tool in research of irregular adoptions and abduction of newborns in Spain: National Institute of Toxicology and Forensic Science (Department of Barcelona) experience

Introducción. Los casos de adopciones irregulares y sustracción de recién nacidos en España han tenido una gran repercusión social, lo que ha conllevado la elaboración de reformas normativas y el desarrollo de guías y recomendaciones científicas que ayuden a su investigación. El objetivo del presente estudio fue la identificación genética de las muestras remitidas mediante estudios de parentesco. Material y métodos. Entre 2011-2014 se recibieron en el Departamento de Barcelona del Instituto Nacional de Toxicología y Ciencias Forenses 58 casos sobre los que se requirió judicialmente un estudio de identificación genética. Se analizaron restos óseos exhumados o muestras clínicas. Tras el estudio previo (antropológico y anatomopatológico) se procedió a la extracción del material genético y su posterior análisis. Resultados. La calidad y cantidad del ADN recuperado permitió el análisis genético en el 67,2% de los casos, frente al 32,8% donde no fue posible. Los datos muestran que mayoritariamente (87,2%) se estableció una relación de compatibilidad paterno-filial, siendo minoritarias las exclusiones (12,8%). El índice de verosimilitud osciló entre 1,75 × 104-5,95 × 1017 y los STR estudiados de 8-21. Conclusiones. Los datos y experiencia adquirida muestran la importancia de la recopilación de la información, de los antecedentes del caso y del estudio antropológico previamente al análisis genético. Esta información permite orientar los estudios genéticos y, ocasionalmente, ayuda a interpretar los resultados. Asimismo, las características de este tipo de muestras obligan a establecer un protocolo de calidad que garantice la autenticidad de los resultados finales (AU)

Introduction. Cases of irregular adoptions and abduction of newborns in Spain have had got a great social impact which has led to regulatory reforms and the implementation of scientific guidelines and recommendations to help their investigation. The objective of the study was the genetic identification of the samples submitted by kinship studies. Materials and methods. In the period between the year 2011 and 2014, the Barcelona Department of the National Institute of Toxicology and Forensic Sciences,received a total of 58 cases on which it was judicially required to carry out a study of genetic identification. Exhumed bones or clinical samples were analyzed. After previous study (anthropological, anatomo-pathological), the extraction of genetic material and its subsequent analysis were carried out. Results. The quality and the quantity of recovered DNA allowed carrying out genetic analysis in 67.2% of cases, compared to 32.8%, where it was not possible. The data show that for the majority ofthe cases studied (87.2%) was established a positive relationship, being minority the cases of exclusion (12.8%). The likelihood ratio (LR) obtained, ranged from 1.75 × 104-5.95 × 1017, and the STR markers studied from 8 to 21. Conclusions. Experience and data show the importance of gathering information, the history related to the caseand the importance of the anthropological study prior to genetic analysis. This information allows orienting the genetic studies and, in some cases, it helps to interpret the results. Also, the characteristics of this type of samples require establishing a quality protocol that ensures the authenticity of the final results (AU)

Trastorno facticio aplicado a otro: doble caso con un resultado de muerte / Factitious disorder imposed on another: double case with a result of death

Presentamos el caso fatal de un lactante intoxicado con tramadol, detectado en hueso después de 28 meses de intervalo posmortem, tras estudio ordenado por la fiscalía por síntomas similares en un hermano superviviente. Las intoxicaciones se produjeron durante su hospitalización por un síndrome convulsivo idiopático y refractario a tratamiento, en el contexto de un trastorno facticio aplicado a otro. Se analiza el modo de presentación del caso, la importancia del equipo de salud en la detección precoz y el enfoque médico-legal para el diagnóstico final (AU)

We present the fatal case of an infant intoxicated with Tramadol detected in bone after an interval of twenty-eight months post mortem, after study ordered by the prosecutor for similar symptoms in a surviving brother. Intoxications occurred during their hospitalization for an idiopathic, convulsive and refractory syndrome to treatment, in the context of a Factitious Disorder imposed on another. We analyze mode of presentation for the case, the importance of health team in early detection and forensic approach for final diagnosis (AU)

[Intentional poisoning of two wives by their husband?]. / Vorsätzliche Vergiftung zweier Frauen durch ihren Ehemann?

The authors report on the death of two women who were married to the same man one after the other. Exhumation and toxicological investigation of the first wife, who had died 7 years before, did not produce any conclusive evidence of homicide. With regard to the circumstances of death of the second wife the husband made different statements. According to the result of the chemical and toxicological investigations death was caused by acute intoxication with the beta-blocker metoprolol. The man was found guilty of killing on request (which is a criminal offence in Germany) by administering the beta-blocker metoprolol through a transnasal gastric tube.

[Identification of an exhumed unknown infant through DNA analysis]. / Identifizierung eines exhumierten unbekannten Säuglings mittels DNA-analyse.

The article reports on the exhumation and subsequent DNA analysis of the skeletal remains of an unknown male newborn from 1988. Molecular biological methods confirmed the maternity of a woman who was already convicted of infanticide. Since homicide could not be clearly proven and manslaughter becomes barred by the statute of limitation after 20 years, the woman cannot be held accountable for the alleged killing of her first child.

Autopsy: Traditional Jewish laws and customs "Halacha".

Judaism has many traditions, customs, rules, and laws, which relate to the proper and ethical disposition of a decedent when a Medical Examiner/ Coroner is involved. In almost all United States jurisdictions, statutes mandate the need to determine the cause and manner of death (Coroners' Act PA Pl. 323, num. 130, section 1237). This article is a review of some religious writings, legal precedents, and forensic authorities, which may help to assist the Medical Examiner/Coroner when confronted with a Jewish decedent. There can be flexibility as to the extent that such forensic studies can and should be performed. The final consent and interpretation of the rules, laws, traditions, and customs will rest with the courts and local rabbinic authority.

[Uncovering an undetected homicide by exhumation]. / Aufdeckung eines verkannten Tötungsdeliktes durch Exhumierung.

The problems of postmortem examinations and the associated dark figure of undetected homicides are well known and have been repeatedly discussed in Germany. The article deals with the case of a 73-year-old woman whose death was initially certified as being natural ("sudden cardiac death"). When secondary suspicious circumstances turned up, an exhumation was ordered three weeks after the burial. At autopsy, signs of multiple blunt force to the occiput, the thorax and the upper extremities as well as compression of the neck were found. The findings proved foreign intervention and suggested death due to suffocation. In the court trial, the accused pleaded an accidental event (fall down stairs). He was sentenced to life imprisonment for murder. The presented case of homicide remained undetected at first, as due to the deceased's advanced age a natural death had been falsely assumed. An obviously very superficial external postmortem examination by the physician was probably the main reason for the misjudgement. The factors "advanced age" and "homicide leaving few external traces and no visible injuries" seem to present special problems and essentially contribute to the dark figure of undetected homicides. Physicians performing postmortem examinations and the general public should be made aware of the problem by regular further education and discussion.

Exchanged identities in a complex multiple homicide case. Identification and cause of death.

We report a multiple homicide in Angola involving six Portuguese citizens. Immediately after the crime, four bodies were retrieved from the homicide site. Forensic autopsies were allegedly performed by local doctors and three bodies were transferred to Portugal, where they were buried with no extra expertise, presumably identified only by the examinations carried out in Angola. The two remaining bodies, presumably from sub-adults, were only discovered 1 year later. At that time, some bone samples of these two corpses were sent to Portugal. A multidisciplinary team of the National Institute of Legal Medicine (NILM) in Portugal, including forensic anthropologist and pathologists, and forensic geneticist, found out that the bodies were previously misidentified. In fact, the anthropological and genetic examinations on the remains of the two persons showed that they did not belong to a child and an adolescent but instead to two adult victims, at least one of them was supposed to be buried in Portugal since 1 year. The verification of this misunderstanding led to a series of exhumations, of the three victims previously buried in Portugal. In all, the identities were reconstructed and the cause of death could be established in four of them. A multiplicity of severe traumatic cranial injuries were detected, which were, undoubtedly due to a violent death.
