RESUMEN
The presence of background DNA (bgDNA) can hinder the evaluation of DNA evidence at the activity level, especially when the suspect is expected to be retrieved due to their habitual occupation of the investigated environment. Based on real-life casework circumstances, this study investigates the prevalence, composition, origin, and probable transfer routes of bgDNA found on personal items in situations where their owner and person of interest (POI) share the same workspace. Baseline values of bgDNA were evaluated on the participants' personal items. Secondary and higher degree transfer scenarios of non-self DNA deposition were also investigated. The DNA from co-workers and co-inhabiting partners can be recovered from an individual's personal belongings. Non-self DNA present on the hands and deposited on a sterile surface can generate uninformative profiles. The accumulation of foreign DNA on surfaces over time appears to be crucial for the recovery of comparable profiles, resulting in detectable further transfer onto other surfaces. For a thorough evaluation of touch DNA traces at the activity level, it is necessary to collect information not only about DNA transfer probabilities but also about the presence of the POI as part of the 'baseline' bgDNA of the substrates involved.

AIM: To clarify the role of the ethanol metabolites, ethyl glucuronide (EtG) and ethyl sulfate (EtS), in monitoring alcohol consumption. METHOD: We recruited 7 female and 17 male volunteers who were instructed to consume a quantity of beer (containing 48 gm ethanol) with food in one session. We examined urinary excretion of EtG and EtS over time and looked for correlations between the concentrations of the metabolites EtG and EtS. RESULTS: EtG concentrations in urine varied between 0.026 and 430.372 µg/ml with average values between 11.85 µg/ml (SD 19.75), 30 min after alcohol intake, and 100.39 µg/ml (SD 101.34), 4.5 h after alcohol intake. EtS urinary concentration ranged from 0.006 to 101.432 µg/ml with average values between 4.77 µg/ml (SD 5.42), 30 min after alcohol intake, and 30.14 µg/ml (SD 27.20), 4.5 h after alcohol intake. Spearman's test showed that urinary EtG and EtS correlated significantly at several time points. CONCLUSION: The great interindividual variability in their excretion suggests caution in the use of urinary measurement of these metabolites in forensic investigations.

BACKGROUND: Laparoscopic cholecystectomy (LC) is considered to be the gold standard in the early management of acute cholecystitis however, recommendations for routine drain insertion in the acute setting are unavailable. STUDY DESIGN: A systematic review of literature review and metanalysis was conducted. All studies comparing drain versus no drain after LC for acute cholecystitis were included. RESULTS: Seven studies, with 1274 patients, were included. Postoperative wound infection rates (relative risk (RR) 0.30, 95% confidence interval (CI) 0.10 to 0.88; I2 = 0%) and postoperative abdominal collection requiring drainage (RR 1.20, 95% CI 0.35 to 4.12; I 2 = 0%) were lower in the no-drain group, but this was only significant for wounded infections on subgroup analysis of RCTs. Length of stay hospital (mean difference (MD) -0.49, 95% CI -0.89 to -0.09; I 2 = 69%) and operative time (MD -8.13, 95% CI -13.87 to -2.38; I 2 = 92%) were significantly shorter in the no drain group however this was in the context of significant heterogeneity. CONCLUSION: The available data suggests that acute cholecystitis is not an indication for routine drain placement after LC. However, these results must be interpreted with caution due to the limitations of the included studies. In effect, the main issue of this meta-analysis lies on the limitations of the included studies themselves, because of a considerable heterogeneity among the included works, particularly for the inclusion criteria of patients and reported severity of acute cholecystitis. Further work is required to produce evidence which will definitively alter clinical practice. LEVEL OF EVIDENCE: Level 2a (systematic review of cohort studies). Oxford CEBM levels of evidence.

BACKGROUND: The purpose of this systematic review and meta-analysis was to determine the prevalence of the number of sigmoid arteries (SA) and variations in their origins. METHODS: A thorough systematic search of literature through February 2020 was conducted on major electronic databases to identify eligible studies. Data were extracted and pooled into a meta-analysis using Metafor package in R. The primary outcome was the variations in the SA origin (according to modified Zebrowski classification), and the secondary outcome was the prevalence of the number of SA. RESULTS: A total of 22 studies (n = 2653 patients) were included. Type 1 modified Zebrowski (separated origins or common trunk of the SA originating from descending recto-sigmoid trunk (DRST)) was the most common origin type of the SA (pooled prevalence estimate (PPE) = 49.67% (95% CI 32. 67- 66.71)), while type 3 (separated origins or common trunk of 1 or 2 SA originating from DRST or superior rectal artery (SRA) and 1 or 2 SA originating from DRST or SRA) was the least common (PPE = 0.18%; 95% CI 0.00-2.82)). Of the Type 1 variants, the not specified (N.S) variant was by far the most prevalent. The number of SA ranged from one to five, with three being the mode (PPE = 42.3%). CONCLUSION: This is the most comprehensive analysis of arterial vascular anatomy of the sigmoid colon. In light of the highly variable anatomical pattern displayed by the SA, thorough pre-operative knowledge of their anatomy can be crucial in minimizing incidences of iatrogenic injury.

BACKGROUND: Nerve identification is recommended in inguinal hernia repair to reduce or avoid postoperative pain. The aim of this prospective observational study was to identify nerve prevalence and find a correlation between neuroanatomy and chronic neuropathic postoperative inguinal pain (CPIP) after 6 months. MATERIAL: A total of 115 patients, who underwent inguinal hernia mesh repair (Lichtenstein tension-free mesh repair) between July 2018 and January 2019, were included in this prospective observational study. The mean age and BMI respectively resulted 64 years and 25.8 with minimal inverse distribution of BMI with respect to age. Most of the hernias were direct (59.1%) and of medium dimension (47.8%). Furthermore, these patients were undergoing Dermatome Mapping Test in preoperatively and postoperatively 6 months evaluation. RESULTS: Identification rates of the iliohypogastric (IH), ilioinguinal (II) and genitofemoral (GF) nerves were 72.2%, 82.6% and 48.7% respectively. In the analysis of nerve prevalence according to BMI, the IH was statistically significant higher in patients with BMI < 25 than BMI ≥ 25 P (< 0.05). After inguinal hernia mesh repair, 8 patients (6.9%) had chronic postoperative neuropathic inguinal pain after 6 months. The CPIP prevailed at II/GF dermatome. The relation between the identification/neurectomy of the II nerve and chronic postoperative inguinal pain after 6 months was not significant (P = 0.542). CONCLUSION: The anatomy of inguinal nerve is very heterogeneous and for this reason an accurate knowledge of these variations is needed during the open mesh repair of inguinal hernias. The new results of our analysis is the statistically significant higher IH nerve prevalence in patients with BMI < 25; probably the identification of inguinal nerve is more complex in obese patients. In the chronic postoperative inguinal pain, the II nerve may have a predominant role in determining postoperative long-term symptoms. Dermatome Mapping Test in an easy and safe method for preoperative and postoperative 6 months evaluation of groin pain. The most important evidence of our analysis is that the prevalence of chronic pain is higher when the nerves were not identified.

BACKGROUND: The Aberrant Left Hepatic Artery (ALHA) is replaced when it does not originate from the hepatic artery proper and it is the only supply to that part of the liver, while an accessory artery coexists with a normal artery. The aim of this systematic review is to evaluate the incidence of ALHAs including the one arising from the Left Gastric Artery, also named Hyrtl's artery. METHODS: A literature search in PubMed, SCOPUS, WOS and Google Scholar was performed. The risk of bias was assessed by means of the AQUA tool. The main outcome was the prevalence of ALHA. Secondary outcomes were the prevalence of the accessory and replaced left hepatic arteries. A subgroup analysis was conducted by geographic region and type of evaluation. RESULTS: This review included 57 studies, with a total of 19,284 patients. The majority of the studies involved the use of radiological techniques -especially Angio-CT-and were performed in Asia. The overall risk of bias was moderate. The overall prevalence of the ALHA was 13.52%; the overall prevalence was 8.26% for the Replaced ALHA and 5.55% for the Accessory ALHA. In the 18 studies that employed Michels' classification, Type II had the lowest prevalence (0.36%) and Type VII the highest prevalence (6.62%). DISCUSSION: Some of the studies included did not distinguish between the ''replaced'' and ''accessory'' ALHA (34.25%). Some surgical dissection techniques proved insufficient for the localization of other hepatic arteries. These results suggest that an accurate preoperative radiological evaluation is needed to localize replaced arteries.

BACKGROUND: The incidence of taking selfies and sharing them on social media as well as selfie-related dangerous behaviors is increasing, particularly among young people, also leading to selfie-related trauma and death. This study was performed to obtain epidemiological characteristics of selfie-related mortality in Italy. METHODS: Scientific literature and Italian media were reviewed. RESULTS: Twelve victims from 11 events, from 2014 to 2018, were analyzed (sex, age, accident types, the nationality, the Italian region where the incident took place, if the person involved was indigenous or a tourist, the dynamics and the causa mortis, if other people have been involved in the selfie, and if other people were deceased). The majority of selfie victims were male teenagers, the average age was 23.6 years, the most preferred site of taking selfies was the natural environment followed by the railway one, the most frequently reported event or accident type was falling from a height, and the most frequent causes of selfie-related deaths were multitrauma and drowning. CONCLUSIONS: Selfie-related deaths in Italy appear to be an issue and appear to be increasing. Particularly, male teenagers and young adults are at high risk for selfie-related deaths. Measures should be taken to reduce their incidence.

Background and Objectives: The present study aims to assess the effectiveness and current evidence of the treatment of perirectal bleeding after stapled haemorrhoidopexy. Materials and methods: A systematic literature review was performed that combined the published and the obtained original data after a search of PubMed, Web of Science, and SCOPUS. Results: The present systematic review includes 16 articles with 37 patients. Twelve papers report perirectal and six report intra-abdominal bleeding. Stapled hemorrhoidopexy (SH) was performed in 57% of cases (3 PPH 01 and 15 PPH 03), stapled transanal rectal resection (STARR) in 13%, and for 30% information was not available. The median age was 49 years (±11.43). The sign and symptoms of perirectal bleeding were abdominal pain (43%), pelvic discomfort without rectal bleeding (36%), urinary retention (14%), and external rectal bleeding (21%). The median time to bleeding was 1 day (±1.53 postoperative days), with median hemoglobin at diagnosis 8.8 ± 1.04 g/dL. Unstable hemodynamic was reported in 19%. Computed tomography scan (CT) was the first examination in 77%. Only two cases underwent the abdominal US, but subsequently, a CT scan was also conducted. Non-operative management was performed in 38% (n = 14) with selective arteriography and percutaneous angioembolization in two cases. A surgical treatment was performed in 23 cases - transabdominal surgery (3 colostomies, 1 Hartmann' procedure, 1 low anterior resection of the rectum, 1 bilateral ligation of internal iliac artery and 1 ligation of vessels located at the rectal wall), transanal surgery (n = 13), a perineal incision in one, and CT-guided paracoccygeal drainage in one. Conclusions: Because of the rarity and lack of experience, no uniform tactic for the treatment of perirectal hematomas exists in the literature. We propose an algorithm similar to the approach in pelvic trauma, based on two main pillars -hemodynamic stability and the finding of contrast CT.

INTRODUCTION: The common hepatic artery (CHA) is the main arterial supply to the liver. Common classifications of the anatomical variations of the celiac trunk have only marginally described the CHA. Currently, the only classification addressing anatomical variants in cases of CHA absence from the celiac trunk is that reported by Huang et al. In this systematic review, the prevalence of these variations, according to Huang's classification, have been analyzed. METHODS: The review was registered in PROSPERO (CRD 42018096679). The risk of bias was assessed using the AQUA tool. RESULTS: Fifty-four articles were included in the review (26,250 participants). The overall pooled prevalence estimate (PPE) of an absent CHA was 3.1%. Of those participants who underwent preoperative radiological evaluation, the overall PPE of an absent CHA was 3.8% for subjects who were evaluated via angiography and 3.0% for participants who underwent angio-CT evaluation. The overall PPE of an absent CHA was 3.9% in cadavers and 3.2% in participants evaluated surgically. Type I or Type II aberrations were the most common; in participants with CHA aberrations, 65.4% of those participants had either Type I or Type II aberrations. CONCLUSIONS: The overall PPE of an absent CHA was 3.1%, a result representing a significant, common anatomical variation. Our study revealed that an absence of a CHA was associated with a replaced CHA. The most common arterial variant was a replaced CHA originating from the Superior Mesenteric Artery and running across the anterior or posterior side of the pancreas (i.e., Types I and II).

The authors report a case of a man who developed stroke symptoms a few days after a road accident on his motorcycle. Radiographic examinations revealed the presence of bilateral dissection of the extracranial internal carotid arteries with signs of involvement of the brain parenchyma.The location, timing, and presentation lead to the conclusion that the carotid lesions were secondary to the motorcycle collision; in particular, we suppose that it is due to the pressure exerted by the helmet strap worn. Although helmets have undoubtedly prevented serious injuries, this report highlights that the helmets themselves may cause injuries, especially to cervical soft tissues and vessels.

Impalement injuries occur when a large foreign body traverses or penetrates a body cavity or extremity. Nowadays, impalement injuries are uncommon and are usually a consequence of a fall onto a blunt object or a road accident. The authors report a case of a woman found dead in her apartment, seemingly killed by a firearm injury to the abdomen. However, after the autopsy was carried out, it became clear that the injuries had the features of an impalement. After the inquiry, the murder weapon was identified as a battering ram, used by the robbers to break into the house of the woman. This is the first case ever described in literature where a battering ram has been used to impale someone. This case emphasizes the importance of an accurate description of injuries, also with photographs, in order to achieve effective recognition of the wound patterns as they may correspond to specific and unusual weapons.

Forensic pathologists are requested to select matrices alternative to blood in cases of toxicological interest in which blood is not available for different reasons. We evaluated morphine concentrations in blood, bile, and liver samples in 52 cases of heroin overdoses, relating them to each other, to understand the information that could be derived from their analysis. Gas chromatography/mass spectrometry analysis was performed for all the samples positive on screening for opiates. Shapiro-Wilk test, nonparametric Mann-Whitney test, linear regression analysis, and Bland-Altman test were used for analysis. Linear regression demonstrated that there was not a statistically significant association in morphine concentrations between blood and bile and blood and liver. Mean liver/blood ratio was 2.76, varying from 0.131 to 13.379, and bile/blood ratio was 28.79, varying from 0.28 to 559.16. According to these results, bile analysis is a "screening test"; biliary or hepatic concentration of morphine cannot provide information on hematic concentration at the time of death, having no forensic value taken individually.

Background: The analysis of drug traces on banknotes with different validated techniques can provide important information about the types of substances that are used in a geographical region. The aim of our review was to investigate banknotes' contamination by cocaine, by its metabolite, but also by other drugs. Methods: A systematic literature search (English written literature) was conducted in MEDLINE, and Scopus, collecting studies from 1974 till 2017. The Key search terms included: 'banknote AND drug'; 'banknote AND cocaine'. Results: The literature search yielded 88 publications; 9 were included in our review. In six studies that showed banknotes' positivity to cocaine, the percentage ranged from 2.5% to 100%. The concentration of cocaine ranged from 0.09 ng/note to 889 µg/note. Benzoylecgonine was indentified only in three studies with a range from 0.71 to 130 ng/note. Other indentified drugs were: amphetamine derivatives, opiates, benzodiazepines. Conclusions: Circulating banknotes could be used to indicate substances used in a population, and those recently introduced in a geographical macro-area. The identification of very high amounts of cocaine can provide important information for the identification of banknotes used in illegal trafficking.

Pulmonary ThromboEmolism (PTE) is an important disease for legal medicine. Because of their sudden lethal onset, generally medicolegal autopsies show few clinical information when PTE is the cause of death. During medicolegal autopsies, the autopsy operator must answer to important questions. For example, autopsy operator can need to assess the casual relationship between PTE and recent accident, such as trauma or long air travel. Furthermore, the autopsy operator needs to investigate the pathology of PTE as a cause of sudden cardiovascular death. It is relatively simple to confirm a fatal massive thromboembolus in the initial stage of thoracic investigations, but sometimes it might be difficult to distinguish this from postmortem clot. In such cases histopathological examination can help in the differentiation. Histological examination is also required for observation of chronological changes of the thrombi. Chronological evaluation is an important factor especially to determine whether the death coincides with the date of a specific accident/event or instead there is an earlier onset of PTE. In addition, histological sections sometimes show additional information, such as tumor fragments in cases of malignancy or small fragments of bone marrow in cases of active resuscitation, that can be useful in a medicolegal scenario. Furthermore, new diagnostic tools are arising, which they can be very helpful in the individuation of this frequently underdiagnosed disease. The goal of our work is to investigate these aspects through the review of the recent literature.

Since tramadol was marketed, it has been widely prescribed as a pain killer because of its relatively safe profile among opioids.Nevertheless, intoxication can occur: overdose can lead to fatal outcomes mostly in association with other drugs, via the potential interaction with serotonergic antidepressant medications, as well as the potential for increased central nervous system (CNS) depression.Fatal outcomes only attributable to tramadol are a rare entity. In this case report, 2 fatal cases are described due to tramadol stand-alone intoxication with peculiar characteristics.In case 1, gas chromatography - mass spectrometry analysis detected tramadol in all specimens (32 µg/mL in the heart blood, 23.9 µg/mL in the femoral blood, 3.3 µg/mL in the bile, and 1.4 µg/mL in the urine). No other CNS depressants were detected by toxicological analysis.In case 2, gas chromatography - mass spectrometry analysis detected tramadol in all specimens (7.5 µg/mL in the heart blood, 5.8 µg/mL in the femoral blood, and 18 µg/mL in the urine). No other CNS depressants were detected by toxicological analysis.Review of the literature was performed to clarify the actual knowledge on this topic.

Sudden death due to inhalation of aliphatic hydrocarbons such as butane and propane is well described in the literature. The main mechanism involved is the induction of a fatal cardiac arrhythmia. This phenomenon is frequently associated with prisoners who accidentally die while sniffing these volatile substances with an abuse purpose. Furthermore, such prisoners are often under psychiatric treatment; specific drugs belonging to this pharmacological class lead to a drug-related QT interval prolongation, setting the stage for torsade de pointes. In this article, we present the case of a prisoner died after sniffing a butane-propane gas mixture from a prefilled camping stove gas canister. The man was under psychiatric drugs due to mental disorders. He was constantly subjected to electrocardiogram to monitor the QTc (corrected QT interval), which was 460 milliseconds long. Toxicological analysis on cadaveric samples was performed by means of gas chromatography (head space) and revealed the presence of butane and propane at low levels. The aim of this article was to discuss a possible arrhythmogenic interaction of QT interval prolongation induced by psychiatric drugs and butane-propane inhalations, increasing the cardiovascular risk profile. In other words, evidence may suggest that prisoners, under these circumstances, are more likely to experience cardiovascular adverse effects. We believe that this study underlines the need to take this hypothesis into account to reduce death risk in prison and any medical-related responsibilities. Further studies are needed to validate the hypothesis.

Forensic autopsy, like the other sectors in medicine, has benefited from the technological progress and the creation of multidisciplinary teams to unveil more and more finely planned criminal intents.Forensic pathologists, however, can sometimes deal with very enigmatic cases, meeting so with the limits of their own knowledge. Therefore, in these cases, they must not allow themselves to be pressured by inquiring agencies, remaining instead always faithful to empiric observations.With regard to that, we present a peculiar case of death by shredding inside a grinding machinery. The magistrature consequently opened a dossier for willful murder. Lots of figures were appointed to solve the case and among them is the forensic pathologist. However, a great number of obstacles were put in the investigators' inquiries.Was it a perfect murder?

Long-distance truck drivers have been found to be associated with many medical problems because of their lifestyle and work environment. Many studies have revealed an increased risk in sexually transmitted infections, musculoskeletal disease, sleep disorders, hypertension, gastrointestinal disease, substance abuse and alcoholism, lung cancer, as well as human immunodeficiency virus infection. To our knowledge, there are no any articles about a fatal case of pulmonary thromboembolism. We report a case of a 45-year-old truck driver, who was found dead in his truck at a service station along the A1 motorway in Umbria, Italy. Autopsy findings revealed pulmonary thromboembolism as cause of death. Our report underlies that future actions must be addressed to provide health care access to this vulnerable, medically underserved population.

The authors report the case of an accidental death of a 3-year-old child who unintentionally shot himself while he was handling his father's handgun.The peculiarity of the observed injury makes the case particularly interesting, along with the fact that, in Italy, unintentional firearm-related deaths are rather uncommon among children and adolescents.Because of the presence of only 1 bullet hole on the parietal-occipital region, radiological cranial examinations were performed before proceeding with the autopsy.Computed tomographic scans were useful to confirm the entrance site of the bullet and, especially, to establish the trajectory with the whole spectrum of fractures.The case shows that the unusual entrance site of the bullet through the nose led to a fatal cranial injury, as a result of curiosity of a 3-year-old child in the presence of an unsupervised handgun.
