Collagen and elastic fibers assessment of the human heart valves for age estimation in Thais using image analysis
AbstractThe study investigated the relationship between the histological compositions of the tricuspid, pulmonary, mitral, and aortic valves, and age. All 85 fresh human hearts were obtained with an age range between 20 and 90  years. The central area of the valves was conducted to analyze the density of collagen and elastic fibers by using an image analysis program. Neural network function in MATLAB was used for classification data and accuracy test of the age predictive model. Overall, a gradual increase in the density of collagen and elastic fibers was demonstrated with age in all valve types. The pulmonary valve cusps...

A novel conservative technique to allow oral opening and overcome rigor mortis during medicolegal autopsy
This study presents a novel conservative technique to increase oral opening and overcome rigor mortis during medicolegal autopsy (MLA). The method proposes a myotomy of the temporalis and masseter muscles, taking advantage of the incisions of the cranial opening procedures, to achieve a significant oral opening ( ≥ 30 mm) in fresh cadavers with established rigor mortis without altering facial aesthetics. The study was performed on 48 individuals aged between 18 and 66 years (20 males and 28 females) who were autopsied at the Instituto Nacional de Patología Forense Dr. Sergio Sarita Valdez (Santo Doming o, Dominican R...

Mechanical trauma in children and adolescents in Berlin
This study analyzes trauma mechanisms in deceased pediatric patients. Fatal pediatric trauma cases aged 0 –18 years who underwent forensic autopsy in the Federal State of Berlin, Germany, between 2008 until 2018 were enrolled in this retrospective study. Autopsy protocols were analyzed regarding demographic characteristics, trauma mechanisms, injury patterns, resuscitation measures, survival times as well as place, and cause of death. 71 patients (73% male) were included. Traffic accidents (40%) were the leading cause of trauma, followed by falls from height >  3 m (32%), railway accidents (13%), third party viol...

Self-mutilation: a systematic review
AbstractSelf-mutilation lesions can represent a clinical diagnosis challenge for healthcare professionals, as patients do not admit to self-mutilation. This leads to failed diagnoses due to the similarity of this condition to other diseases. Searches on the subject were carried out at the PubMed, Peri ódicos Capes, Scopus, Science Direct and WoS databases, according to the following inclusion criteria: articles in English, Portuguese or Spanish, published from 2018 to June 2023, encompassing case reports, case series and literature reviews. Men are slight more affected by self-mutilation injurie s, also presenting the mos...

A fatal misdiagnosis of page kidney – case report
AbstractPage kidney is a condition where external compression of the renal artery and renal parenchyma leads to subsequent ischaemia and activation of renin-angiotensin-aldosterone axis. A 42-year-old female with hirsutism, hypertension and diabetes was diagnosed with a right adrenal mass and underwent laparoscopic adrenalectomy. Her hypertension worsened postoperatively and was managed medically. Subsequently she developed a right flank pain on the fifth postoperative day and died suddenly the next day. Autopsy revealed a pale body with cushingoid appearance. Surgical scars were healthy. Internal examination of the abdome...

Traumatic fractures in an early 19th century museum skeleton suggest the homicide of an old Munich character: the history of “Finessensepperl” (Finesse Joseph)
AbstractThe well preserved skeleton of Joseph Huber, a very well-known historical character of the 19th century Munich, also nicknamed “Finessen-Sepperl”, is the starting point of the reconstruction of life and death of this historical individual. He was known as apostilion d ´amour (love ’s messenger) of the Royal Bavarian capital with numerous comments and anecdotes and a few biographical sketches that indicate he remained well until the last few years of his life where requests for his duties lessened. The skeleton shows a small-sized male individual with almost complete loss of teeth, but otherwise very well-min...

Acanthosis nigricans – a potentially useful clue to the presence of significant occult disease at autopsy
AbstractA 19-year-old male was found dead in his apartment. At autopsy he was morbidly obese (Body mass index; BMI – 40.5) with multiple areas of velvety pigmented thickening of the skin in folds around the neck, in the axillae, in the inframammary regions, over the anterior waistline and groin regions and over the dorsal aspects of the feet. These had the typical appearance of acanthosis nigricans. Internal e xamination revealed aspiration of gastric contents into the airways. Vitreous humour biochemistry showed markedly elevated levels of both glucose (62.9 mmol/L) and β-hydroxybutyrate (13.54 mmol/L). Death was, th...

Determination of lamotrigine in human plasma by HPLC-PDA. Application to forensic samples
ConclusionA new HPLC method for the determination of lamotrigine in human plasma was developed and validated. A liquid-liquid extraction using small volumes of buffer and ethylacetate was optimized. The proposed method is suitable for forensic toxicological analysis. (Source: Forensic Science, Medicine, and Pathology)

InDEL instability in two different tumoral tissues and its forensic significance
In conclusion, low InDel mutation rates compared to STR instability, make InDel analysis from paraffin blocks suitable for forensic genetic identification. However, researchers should keep in mind that there may be differences between the profiles of the tumoral tissues taken as reference and the actual case. In addition, by incorporating additional markers such as SNPs and microhaplotypes with low mutation rates into the study alongside Indels, researchers can significantly enhance the discrimination power in identification processes.

Estimating dental age of New Zealand juveniles and subadults using Demirjian's method
AbstractReference data for dental age estimate is sparse in New Zealand (NZ), with only two contemporary studies. Te Moananui et al. (J For Sci. 53(2),2008) presented modified Demirjian percentile curves to estimate dental age of Pasifika, M āori, and European males and females (n = 1383), while Timmins et al. (Forensic Sci Med Pathol. 8:101–8, 2012) found the Demirjian method (1973) was valid for a smaller sample (n  = 200) of unknown ancestry. The study presented here sought to validate the Demirjian and the Te Moananui methods for a sample of the NZ population of unknown ancestry and a subgroup of known anc...

Assessment of pheniramine in alternative biological matrices by liquid chromatography tandem mass spectrometry
In this study, pheniramine was quantified in both conventional and alternative specimens of twenty chronic drug abusers, aged 16 –50 years, who were positive for pheniramine in comprehensive toxicological screening for drugs by gas chromatography with mass spectral detection in positive electron impact mode. Pheniramine was extracted from biological specimens using solid phase extraction and liquid chromatography tandem ma ss spectrometry was employed for quantification. Chromatographic separation was carried out on a Poroshell120EC-18 (2.1 mm × 50 mm × 2.7 µm) column using water-acetonitrile in formic acid (0...
