Applications of Tandem Mass Spectrometry (LC–MSMS) in estimating the post-mortem interval using the biochemistry of the vitreous humour
We present a new LC–MSMS method developed for quantitative and qualitative analysis of [Hx] (valid also for guanine and xanthine), and qualitative determination of uric acid in vitreous humour. We also introduce a methodology to assess haematic contamination in order to improve the estimation of time since death. The method was fully validated in terms of linearity, sensitivity, imprecision, analytical recovery, extraction and process efficiency and matrix effect.

Exploratory data analysis for the interpretation of low template DNA mixtures
Abstract: The interpretation of DNA mixtures has proven to be a complex problem in forensic genetics. In particular, low template DNA samples, where alleles can be missing (allele drop-out), or where alleles unrelated to the crime-sample are amplified (allele drop-in), cannot be analysed with classical approaches such as random man not excluded or random match probability. Drop-out, drop-in, stutters and other PCR-related stochastic effects, create uncertainty about the composition of the crime-sample, making it difficult to attach a weight of evidence when (a) reference sample(s) is (are) compared to the crime-sample. In ...

Age changes of facial measurements in European young adult males: Implications for the identification of the living.
This study investigates changes in facial measurements in European males aged between 20 and 30 years in order to identify metric characters that can be used for personal identification in young adults. A sample of 404 males of European ancestry, aged between 20 and 30 years from Germany, Italy and Lithuania were recruited for this project. Fourteen facial measurements were taken and correlation coefficients were calculated for each cranial measurement with age. Only two measurements - labial width and physiognomic ear length - seem to change between 20 and 30 years with a positive statistically significant correlation (p&...

Mexican mestizo population sub-structure: effects on genetic and forensic statistical parameters.
Abstract Since Mexican mestizos are an admixed population, it is necessary to determine the effects that the substructure of the population has on genetic and forensic parameters. With this aim, a study was performed with 15 STR loci (CODIS plus D2S1338 and D19S433) on 1,640 unrelated Mexican mestizos. We determine allele and genotypic frequencies observing departure from Hardy-Weinberg expectation (12 out of 15 loci, with an excess of homozygotes, Fis > 0), as well as pairs of loci in an apparent linkage disequilibrium (13 of 92 loci). We conducted a test for genetic population stratification, the results sho...

An autopsy case of bilateral adrenal pheochromocytoma-associated cerebral hemorrhage
Abstract: The autopsy findings of a 30-year-old woman who died of cerebral hemorrhage induced by bilateral adrenal pheochromocytoma are presented. The cerebral hemorrhage was shown on the left cerebral hemisphere widely. Her both adrenal glands were severe swelling, and their parenchyma was occupied by a dark red-brown tumorous positive for chromogranin A. The serum catecholamine and their metabolite, vanillylmandelic acid (VMA) levels were markedly high. Furthermore, cardiac hypertrophy and sclerosis of the arteries of various organs had progressed, suggesting an influence of persistent endocrinal hypertension. The measur...

A one step multiplex PCR assay for rapid screening of East Asian mtDNA haplogroups on forensic samples
Abstract: The mitochondrial DNA (mtDNA) haplogroup typing has become an essential tool to study human evolutionary history and to infer the matrilineal bio-geographic ancestry. In forensic field, the screening of mtDNA haplogroups by genotyping of mtDNA single nucleotide polymorphisms (SNPs) can help guarantee the quality of mtDNA sequence data as well as can reduce the need to sequence samples that do not match. Here, a multiplex mutagenically separated (MS) polymerase chain reaction (PCR) system was developed for simultaneous rapid detection of 14 coding region SNPs and one deletion motif representing common mtDNA haplog...

Child abuse followed by fatal systemic Pseudomonas aeruginosa infection
Abstract: Child abuse has become an increasingly serious diagnostic challenge for physicians. The clinical manifestations include malnutrition and sometimes infection. In fact, stress in children has been reported to increase corticosteroid levels. As a consequence, the thymus begins an involution process, producing a severe impairment in cellular and humoral immunity.Here, we report the case of a 7-year-old child who suffered a prolonged history of abuse and died from a systemic Pseudomonas aeruginosa infection. An initial local chronic infection propagated to the pelvic lymph nodes in an immunologically weak body and evo...

Risks of non-lethal weapon use: Case studies of three French victims of stinger grenades
Abstract: The development of non-lethal weapons started in the 1960s. In France, they have been used by the police for about 10 years.We relate the cases of three French women, victims of stinger grenades, non-lethal weapons recently adopted by the French law enforcement to distract and disperse crowds. The three victims presented serious injuries requiring emergency surgical care. One lost her eye.Based on these cases, we discuss the lethal character of these weapons and propose measures to be taken to prevent their dramatic consequences.Although the danger is obviously less than for firearms, stinger grenades are nonethe...

Indicators for acute hypoxia—An immunohistochemical investigation in cerebellar Purkinje-cells
Abstract: The Purkinje-cells (PCs) of the cerebellum are highly vulnerable to hypoxic/ischemic insult. Calbindin-D28k is a calcium-binding protein that is strongly expressed in PCs. Following hypoxia, a decrease in its concentration has been found in animal models before any morphological change of the PCs took place. Hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) are increasingly expressed in tissues that undergo durations of hypoxia, and also in brain tissues.We examine whether a change in expression of any of these factors, or a combination of alterations, is an indicator of acute h...

Conventional Forensic Theory on Order of Bugs That Feast on Corpses Upended
When a human body calls it quits, it can take as few as 30 seconds for blowflies to begin feasting on it. For the next several hours to days, a carnival of blowflies, other flies and beetles make the departed their personal bed-and-breakfasts. A determination of that succession of insects is one of the tools that crime-scene investigators (CSIs) use to estimate the postmortem interval (PMI), or the time elapsed since death. [More]

Latent adrenal Ewing sarcoma family of tumors: A case report
We report an autopsy case of suicidal hanging, in which adrenal ESFT was incidentally revealed. To our knowledge, this is the first case of latent ESFT arising from the adrenal gland. Autopsy can sometimes reveal latent disease. Some of these latent diseases are very rare and we would not be able to detect them without a complete autopsy. As forensic pathologists, we should attempt to perform a complete autopsy and report new discoveries for the development of medicine.

Antidote treatment for cyanide poisoning with hydroxocobalamin causes bright pink discolouration and chemical–analytical interferences
Abstract: Here we report the case of a 70-year-old woman who committed suicide by cyanide poisoning. During resuscitation cares, she underwent an antidote treatment by hydroxocobalamin. Postmortem investigations showed marked bright pink discolouration of organs and fluids, and a lethal cyanide blood concentration of 43mg/L was detected by toxicological investigation. Discolouration of hypostasis and organs has widely been studied in forensic literature. In our case, we interpreted the unusual pink coloration as the result of the presence of hydroxocobalamin. This substance is a known antidote against cyanide poisoning, in...

Reliability of Schmeling’s stages of ossification of medial clavicular epiphyses and its validity to assess 18 years of age in living subjects
Abstract Nowadays, due to the global increase in migration movements, forensic age estimation of living young adults has become an important focus of interest. Minors often have no identification documents providing their correct birth dates. Establishing the age of majority is therefore fundamental in order to determine whether juvenile penal systems or penal systems in force for adults are to be applied. Radiological examination of the clavicles is one of the methods recommended by the Study Group on Forensic Age Diagnostics. In this retrospective study, a sample of chest radiographs of 274 subjects, aged ...

Skeletal age estimation in Hungarian population of known age and sex
Abstract: Several methods of estimating age on the basis of human skeletal remains are used all over the world, methods that were established using known age and sex databases or during medicolegal autopsies. Over the course of the past several decades, many tests have been carried out on various populations to confirm the applicability of these methods in age assessment. While the opinions of experts vary regarding the cranial suture closure techniques, morphology of the sternal end of the fourth rib has been proven to be more accurate as an age assessor. The purpose of this paper is to test the reliability of three age e...

Armanni-Ebstein Lesions: A Need for Clarification.
Abstract Armanni-Ebstein lesions were first described by Luciano Armanni, a pathologist at the University of Naples, during autopsy studies undertaken in 1872, as a unique vacuolar nephropathy associated with poorly controlled diabetes that involves selective renal epithelial cell glycogen accumulation. However, within the last two decades, a broader range of vacuolar changes, including lipid deposition, have also been termed Armanni-Ebstein (AE) lesions, creating some confusion on possible etiology. We would suggest that the term AE phenomenon would be best reserved for the original clear cell change associated wi...

2D Barcodes: A Novel and Simple Method for Denture Identification.
Abstract Several methods of denture marking have been described in the literature. However, most of them are expensive, time-consuming, and do not permit the incorporation of large amounts of information. We propose a novel and simple method incorporating 2D codes which has several advantages over the existing methods. A 2D code was generated in the dental office and inserted into a maxillary denture. The code was then read using software downloaded into a mobile phone giving access to the website containing details about the patient. The denture was also subjected to durability tests, which did not hamper the effi...

Identification of Tool Marks of a Sickle on a Telephone Cable.
Abstract Linkage of a cutting tool (a sickle) with a telephone cable of 100 pairs of copper wires is reported in a case of theft of a telephone cable. Telephone cables contain numerous insulated copper wires of small diameter inside an outer covering and are stolen for the relatively precious copper. The cutting pattern of the cable can only point to the type of the tool but because of the large number of copper wires, it is practically difficult to make a definite linkage with the tool used to cut the cable by comparing the tool marks. The present work reports the successful attempt of the authors in establishing ...

Identification of Human Remains by DNA Analysis of the Gastrointestinal Contents of Fly Larvae.
Abstract Dipterous fly larvae (maggots) are frequently collected from a corpse during a criminal investigation. Previous studies showed that DNA analysis of the gastrointestinal contents of maggots might be used to reveal the identity of a victim. However, this approach has not been used to date in legal investigations, and thus its practical usefulness is unknown. A badly burned body was discovered with its face and neck colonized by fly larvae. Given the condition of the body, identification was not possible. Short tandem repeat (STR) typing was performed using the gastrointestinal contents of maggots collected f...

Forensic medical examination of adolescent and adult victims of sexual violence
The acute care and examination of a victim of sexual violence must be carried out by a competent forensic examiner in a setting appropriate for crisis intervention, forensic evidence collection, and medical follow up. The aim of forensic evidence and biological material collection is to document an alleged physical or sexual contact between individuals and to corroborate the victim's and the assailant's history. This is why the forensic examiner is expected to be objective and in possession of specialised technical and scientific skills. These skills are addressed and recommendations are made on how to carry out a forensic...

Why is the molecular identification of the forensically important blowfly species Lucilia caesar and L. illustris (family Calliphoridae) so problematic?
Abstract: Species of the fly genus Lucilia are commonly used in forensic investigations to estimate the postmortem interval (PMI). Two close-related species Lucilia caesar and L. illustris are difficult to identify. Previous studies showed that the mitochondrial cytochrome c oxidase subunit I (COI) marker could be used to identify many Lucilia species. However, mixed results were obtained for L. caesar and L. illustris due to some European specimens showing identical haplotypes. Here, we investigated 58 new European male specimens of L. illustris and L. caesar whose morphological identifications were checked and for which ...

Population data for 17 Y-chromosome STRs in a sample from Apulia (Southern Italy)
Abstract: The 17 Y-STR loci included in the AmpFLSTR Yfiler PCR Amplification Kit were analyzed in 98 unrelated healthy males from Apulia (Southern Italy). A total of 97 different haplotypes were identified, of which 96 haplotypes were unique and 1 occurred twice. Allele frequencies for each Y-STR locus in pooled sample and estimated value of gene diversity (GD) were evaluated. The lowest value of GD was observed for DYS392 (0.126) and the highest one (0.936) for DYS385. The HD (haplotype diversity) for the studied Y-STR set showed a value of 0.9994, with an HMP (haplotype match probability) value of 0.0006, while the over...

Polymorphisms upstream of the melanocortin‐1 receptor coding region are associated with human pigmentation variation in a Brazilian population
Conclusion:These data suggest that the rs3212345‐T and rs3212346‐G alleles may have contributed to lighter pigmentation phenotypes in modern humans. Genotyping for these SNPs may prove useful to the fields of molecular anthropology and forensic genetics. Am. J. Hum. Biol. 2012. © 2012 Wiley Periodicals, Inc.

Identification of forensically important Sarcophaga species (Diptera: Sarcophagidae) using the mitochondrial COI gene
In this study, we sequenced the mitochondrial cytochrome c oxidase subunit I (COI) gene of 126 specimens of 56 W European Sarcophaga species and added GenBank data to our database to yield a total dataset of 270 COI sequences from 99 Sarcophaga species to evaluate the COI gene as a molecular diagnostic tool for species identification in this genus. Using two simple criteria (Best Match, BM and Best Close Match, BCM), we showed that the identification success using a mini-barcode region of 127 bp was very low (80.7–82.5 %) and the use of this region is not recommended as a species identifier. In contrast,...

P3 Selective sound sensitivity syndrome (misophonia) and Tourette syndrome
Conclusion Selective sound sensitivity syndrome (SSSS, or misophonia, from the Greek "miso", hatred, and "phonia", sound) is described as a "hate of sound", possibly associated with abnormal activity within the limbic system and its functional connections with the primary auditory cortex and the autonomic nervous system. Misophonia is a relatively rare condition, which can be distinguished from hyperacusis by its sensitivity to the subjective response elicited. This is the first documented case of misophonia reported by a patient with a diagnosis of TS. The phenomenological similarity between misophonia and other subjectiv...
