Congenital diverticula of the left ventricle, very rare malformations, are determined by an abnormal embryonic development of the ventricular wall and can be isolated or associated to other cardiac anomalies. In most of the cases, these pathologies are not symptomatic and in some patients can be associated to ventricular arrhythmia, cardiac rupture with tamponade and sudden death. Authors are presenting the case of a sudden death in an 8-weeks-old newborn due to rupture of a cardiac congenital diverticulum of the left ventricle, discovered only at the moment of the autopsic examination...

Trisomy X (47, XXX) is a sex chromosome aneuploidy condition in which females have an extra X chromosome, compared to the 46, XX karyotype in typical females. There is considerable variation in the phenotype, with some individuals very mildly affected and others with more significant physical and psychological features. However, the trisomy X in this case, without any of these phenotype, is rarely reported. Here, we report a case found during DNA sample collection in a study of genetic polymorphism analysis of loci in Chinese ethnic group, of a female with neither laboratory or clinical signs of Triple X syndrome...

Numerous physiological and pathological mechanisms can cause elevated or lowered body core temperatures. Deviations from the physiological level of about 37°C can influence temperature based death time estimations. However, it has not been investigated by means of thermodynamics, to which extent hypo- and hyperthermia bias death time estimates. Using numerical simulation, the present study investigates the errors inherent in temperature based death time estimation in case of elevated or lowered body core temperatures before death...

Among new psychoactive substances (NPS) available on the narcotic market, a significant number consists of synthetic cannabinoids commonly known as smokable herbal "spice" and "K2", and which are legally treated as a legal alternative to marijuana. The dearth of information on the pharmacology of these intoxicants as they are introduced into the market has created the urgent need among healthcare providers for case studies on the substances belonging to this group, both in terms of the consequences of using such intoxicants, and in methods of detection...

Our aim was to investigate whether sex can be determined from a combination of geometric features obtained from the 10th thoracic vertebra, 6th rib, and 7th rib. Six hundred chest radiographs (300 males and 300 females) were randomly selected to include patients of six age groups (20s, 30s, 40s, 50s, 60s, and 70s). Each group included 100 images (50 males and 50 females). A total of 14 features, including 7 lengths, 5 indices for the vertebra, and 2 types of widths for ribs, were utilized and analyzed for sex determination...

Facial soft tissue thicknesses (FSTT) measurements collected from Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) imaging techniques are most commonly taken in the supine position for forensic craniofacial reconstruction. FSTT have been shown to be different in comparison to the upright position due to gravity. The variation of facial morphology between the upright and supine position of laser-scanned images taken from 44 individuals was investigated using volumetric analysis with deviation maps...

An 84-year-old man who had suffered from chronic obstructive pulmonary disease accompanied by moderate pneumonia as well as gastric cancer with liver metastasis was found dead by a nurse, who noticed that the patient's intravenous catheter in the left forearm had been erroneously connected to an oxygen supply in his hospital room, leading to infusion of oxygen into a vein. Postmortem CT scanning demonstrated multiple accumulations of gas in the pulmonary artery, the right atrium and ventricle, as well as the left subclavian and brachiocephalic veins, corresponding to the route that the infused gas would have taken to the heart and pulmonary artery...

Teeth are markedly useful as samples for DNA analysis; however, intact teeth are not always available. This study examined the possibility of identifying autosomal and Y-chromosome short tandem repeat (STR) types in samples from 34 teeth (15 intact and 19 root canal filled) that had been preserved for 10-33years after dental extraction. The aim was to explore the feasibility of individual identification by DNA analysis of samples obtained from highly decomposed and skeletonized corpses. Only one out of 24 autosomal STR loci was not identified in two of the 15 intact teeth, whereas all 23 loci of the Y chromosome STR were detected...

#12
Ayako Himemiya-Hakucho, Tatsuya Fujimiya
In Japan, low-alcohol dose cases of drunken driving, where drivers drink just before getting behind the wheel, are increasing for expert witnesses since the penalties for drunken driving have become stricter. Widmark's equation has generally been used for the pharmacokinetic analysis of blood alcohol concentration, which encompasses the one-compartment model with zero-order elimination kinetics but ignores absorption kinetics. We therefore propose that the formula might not be applicable to the analysis of low-alcohol dose cases of drunken driving because the issue is focused on the absorption phase...

Allele frequencies for 12 X STR loci (DXS8378, DXS10159, DXS10162, DXS10164, DXS981, DXS6789, DXS7424, DXS101, DXS7133, GATA165B12, GATA31E08 and DXS7423) were obtained from a sample of 518 unrelated individuals from Shaanxi, China. We observed a total of 108 alleles in the group with the allelic frequency values ranging from less than 0.0014 to 0.6768. Our statistic analysis indicates that the 12 X STR conform to the Hardy-Weinberg's equilibrium. Heterozygosity among the studied 12 X STR loci showed a distribution of 42...

The distribution of 17 Y-chromosome short tandem repeat (STR) loci, included in the AmpFlSTR®Yfiler™ amplification kit, were analyzed in six different samplings (N=878) from Sichuan, China. Haplotype diversity and discrimination capacity (DC) values were calculated. Pairwise Rst values were evaluated in AMOVA analysis and visualized through multidimensional scaling (MDS). A total of 547 unique haplotypes were detected. The observed haplotype diversity and discrimination capacity were 0.9995 and 0.7745, respectively...

In this study Cameriere's normalized measurements (CNM) of a single mandibular tooth were evaluated for age estimation on a sample of ortopantomographies (OPTs) of 2223 Italian children aged between 4 and 15years. Dental maturity was radiographically evaluated by CNM of the seven left permanent mandibular teeth (CNMi=Ai/Li, i=1,…,7); in monoradicular teeth, the distance (Ai, i=1,…,5) between the inner sides of the open apex was measured while in biradicular teeth (Ai, i=6, 7), the sum of the distances between the inner sides of the two open apices was calculated...

Allele frequency distribution and statistical parameters of forensic efficiency concerning the Investigator Argus X-12 kit (Qiagen, Hilden, Germany) were determined in a total sample of 641 unrelated Mexican females, including two Mestizo-admixed- populations (n=309) and seven Amerindian groups (n=332) from the main regions of the country. Most of the 12 X-STRs were in agreement with Hardy-Weinberg expectations in all nine Mexican populations. The power of discrimination in females (PD) and Median exclusion chance for trios (MECT) and duos (MECD) of this genetic system based on X-STRs were >99...

PURPOSE: To evaluate the usefulness of the applied freezing technique in putrefied brain for macroscopic investigation. MATERIALS AND METHODS: From October 2015 to September 2016, first the brains of 10 cadavers (control group: male 6, female 4, age 20-80 (mean 61.5), postmortem intervals (PMI) 14-75 (mean 29.7)days) were inspected following the standard practice (without freezing preparation), and then with 10 cadavers (freezing group: male 7, female 3, age 41-88 (mean 60...

The human hip bone is generally accepted as the most reliable bone for sex estimation in forensic and bioarchaeological disciplines. However, it is seldom completely preserved. The best preserved region is typically around the sacroiliac joint and its auricular surface; it is therefore surprising that this surface has not been involved in standard sexing methods. The aim of this study was to explore the shape and size sexual dimorphism of the auricular surface in detail and to compare its sex estimation accuracy using the geometric morphometric (GM) and traditional methodological approach...
