The age estimation practice related to illegal unaccompanied minors immigration in Italy.

The migrants arrived to the Italian coasts in 2016 were 181.436, 18% more than the previous year and 6% more than the highest number ever since. An "unaccompanied minor" (UAM) is a third-country national or a stateless person under eighteen years of age, who arrives on the territory of the Member State unaccompanied by an adult responsible for him/her whether by law or by the practice of the Member State concerned, and for as long as he or she is not effectively taken into the care of such a person; it includes a minor who is left unaccompanied after he/she entered the territory of the Member States. As many as 95.985 UAMs applied for international protection in an EU member country just in 2015, almost four times the number registered in the previous year. The UAMs arrived in Italy were 28.283 in 2016; 94% of them were males, 92% unaccompanied, 8% of them under 15; the 53,6% is 17; the individuals between 16 and 17 are instead the 82%. Many of them (50%), 6561 in 2016, escaped from the sanctuaries, thus avoiding to be formally identified and registered in Italy in the attempt to reach more easily northern Europe countries, since The Dublin Regulations (2003) state that the asylum application should be held in the EU country of entrance or where parents reside. The age assessment procedures can therefore be considered as a relevant task that weighs in on the shoulders of the forensic experts with all the related issues and the coming of age is the important threshold. In the EU laws on asylum, the minors are considered as one of the groups of vulnerable persons towards whom Member States have specific obligations. A proper EU common formal regulation in the matter of age estimation procedures still lacks. According to the Italian legal framework in the matter, a medical examination should have been always performed but a new law completely changed the approach to the procedures of age estimation of the migrant (excluding the criminal cases) with a better adherence to the notions and concepts of vulnerability and psychological and social maturity.

Day to day issues in the forensic identification practice related to illegal immigration in Italy.

The migratory flows to Europe from the African countries, Asia and Middle East, have hugely intensified in the recent years. In 2016, more than 98,000 out of a total of 260,000 migrants across the Mediterranean Sea arrived in Italy and in May 2017, the trend of arrivals is: Italy +576%; Greece -39% compared to previous years. Some migrants die before touching the sole of the European continent, during the crossing, often afforded with ships, made available by unscrupulous smugglers or criminal organizations, which are unsuitable for this type of transportation. The tremendous occurrence of migrant casualties during the Mediterranean Sea crossing remains underestimated and nobody, country officers or databank, can provide a reliable number of dead bodies in such a large and now, endemic phenomenon. Forensic officers, who intervened to examine migrants' corpses, are ideally required to perform the usual activity and to answer the routine questions about the causes of death by detecting signs of possible crimes and body identification. In practice, several specific issues and limits challenge the activity of the forensic professionals addressed to ascertain both circumstances of death and possible related crimes and the identity of the corpses. Generally speaking, in case of examining up to a few dead bodies in Italy, a complete autopsy is performed, whilst, when several tens or hundreds of corpses are recovered, the lack of resources on one hand and clearer clues on incident, connected crimes, and cause of deaths on the other, push the public prosecutor to limit the request of complete autopsies. In some cases, the dead migrants were identified through visual recognition by relatives, friends, or travel companions. The DVI Interpol protocol is never completely applied to dead migrants for several reasons, mainly for the huge difficulties in retrieving AM data of the missing persons and for some limitations affecting both the primary and the secondary identifiers. The few chances of identification by dental data are further reduced by the systematic lack of an odontologist among the forensic teams charged of the PM; valuable dental data for body identification or for constructing the biological profile of the missing person (age, ancestry, country of provenance/residence, etc.) are likely to be overlooked. This approach implies a clear disparity with the approach applied when corpses of citizens of the EU or other developed countries are involved and undergo identification. The dead migrants' identification activity should be reconsidered for an improvement in the common international effort in accordance to an approach more respectful toward the legal rights and dignity of the dead migrants and their families.

Newborn screening of inherited metabolic disorders: the Italian situation.

Starting from an international overview of the current status of screening programs, the present paper focuses on the legal situation in Italy and the great differences among Italian regions. Since the introduction of tandem mass spectrometry (MS/MS) in the ‘90s the paradigm “one spot-one disease” changed. Only recently, some regions issued legislative acts to promote expanded newborn screening with MS/MS. This approach raises medico-legal and ethical issues because a fast neonatal diagnosis of an inborn error of metabolism (IEM) could increase chances of an early treatment and reduce disabilities, therefore citizens ought to have the same access to care countrywide. Enacting a mandatory standard for a disease screening panel using MS/MS and a few centers specialized in diagnosis, treatment and follow-up of patients affected by IEM (inborn errors of metabolism) can reduce legal and ethical issues.

Multiple deaths caused by a fire in a factory: identification and investigative issues.

The article presents a case of multiple casualties following a textile factory fire. The incident required a full DVI team similar to large mass-disaster because of the specific operational aspects and identification difficulties. The autopsy results were consistent with death by fire and the toxicological investigations revealed carbon monoxide poisoning in four cases (HbCO% ranging between 88,05 and 95,77), two deaths by cyanide intoxication (with concentrations between 5,17 and 8,85 mcg/ml), and in one case there was a synergistic effect of the two substances (carbon monoxide and cyanide). The identification, carried out in accordance with INTERPOL protocols, encountered serious difficulties in the AM phase primarily due to a language barrier and the lack of any dental or medical information relating to the victims. Secondary identifiers proved to be very useful in corroborating possible identities. As a result of the combined efforts of a team of experts the identity of each victim was determined and in all cases at least one primary identifier was used in the identification process. The deployment of DVI teams composed of forensic experts from different fields of expertise and well acquainted with DVI procedures, is essential in events involving multiple casualties that may also include foreign victims. The DVI team should intervene not only in PM examinations but also in the collection of AM data for those individuals not accounted for and by helping police in contacting families of missing people.

Whiplash-Associated Disorders : Clinical and medico-legal guidelines on the methods of ascertainment.

The manuscript presents the International Guidelines developed by the Working Group on Personal Injury and Damage under the patronage of the International Academy of Legal Medicine (IALM) regarding the Methods of Ascertainment of any suspected Whiplash-Associated Disorders (WAD).The document includes a detailed description of the logical and methodological steps of the ascertainment process as well as a synoptic diagram in the form of Flow Chart.

Late development of a supernumerary premolar in a 17-year-old female: timing of mineralization and medicolegal considerations.

This report presents a case of a patient who developed a mandibular premolar supernumerary tooth after 14 years of age. Panoramic radiographs show the complete absence of the tooth (or tooth lacuna) at 14 years of age, and the crown as 50 percent developed at 17 years of age. The panoramic radiograph and computed tomography show dislocation of the roots of the adjacent teeth and a morphology similar to a premolar. Although the patient concluded the orthodontic treatment just before the premolar detection on any panoramic radiograph, the parents of the patient complained about the poor information received from the orthodontist.

Early increase in TNF-alpha-containing mast cells in skin lesions.

We have evaluated the numbers and immunohistochemical positivity for tumor necrosis factor (TNF) alpha of the mast cells in (a) 40 skin samples collected at autopsy from subjects who had survived for a few seconds to 1 h, (b) 10 samples of post-mortem skin lesions and (c) 10 surgical biopsies of healthy skin. Sections were treated with fluoresceinated avidin, to tag mast cell granules, followed by indirect immunohistochemistry for TNF-alpha with polyclonal primary and rhodaminated secondary antibodies. We could confirm a progressive increase in mast cell numbers, which became significant 1 h after trauma. More important, the fraction of mast cells positive for TNF-alpha increased progressively in the same time period and became significantly higher than controls in specimens collected more than 15 min after trauma. Samples from post-mortem lesions had significantly fewer mast cells and fewer TNF-alpha-positive cells than any other group of samples. The results suggest that mast cells are quickly recruited to an injured site in response to trauma and upregulate their TNF-alpha content, which can play an early role in directing tissue response to injury. The forensic pathologist can take advantage from this behavior of mast cells for the evaluation of the timing of early vital lesions.

Affinity cytochemistry analysis of mast cells in skin lesions: a possible tool to assess the timing of lesions after death.

The histamine content in vital wounds is known to increase, with a zenith after 3 h, and then decrease until 24 h after wounding. We addressed whether this biochemical alteration has a morphological counterpart. Since the main source of skin histamine are mast cells, the distribution and number of these cells was assessed upon labeling with fluorescent avidin and with antibodies to the mast cell specific enzymes, chymase and tryptase. Analyses were performed on skin from 15 healthy controls (from surgical biopsies), from 15 post-mortem lesions and 75 vital lesions, obtained at autopsy from subjects who had survived from a few seconds to 24 h. The number of mast cells per unit area of section surface increased progressively with survival time, up to a maximum in subjects who survived 1-3 h ( p<0.01), and decreased thereafter becoming less than in the controls if lesions had occurred earlier than 6 h before death ( p<0.01). Samples from post-mortem lesions had significantly fewer mast cells than those of any other groups of samples ( p<0.01). We suggest that in association to other histological and circumstantial evidence the analysis of mast cells by affinity cytochemistry can help to discriminate vital from post-mortem lesions and to estimate survival time after lesions.

Neck motion evaluation after whiplash: a radiographic and kinematic protocol.

Evaluation of functional damage is the main aspect in the diagnosis of whiplash injury, therefore some type of instrumental testing is strongly needed. We describe an instrumental protocol to test subjects with whiplash, to support clinical evaluation, in order to solve the difficulty of evaluating the functional injury and the lack of fixed parameters capable of identifying this kind of injury. Eighty subjects suffering from after effects of whiplash and seventy five normal subjects undergo two instrumental tests: kinematic examination of neck mobility, and measurements of extension-flexion X-rays of the cervical spine. The results exhibited by the traumatized patients have been compared with the normal range of motion obtained from the data bank of the normal subjects. This is a report in progress of a larger research on whiplash evaluation in a clinical setting.

[Professional dental responsibility in HIV virus contagion]. / Responsabilità professionale odontoiatrica nel contagio da virus HIV.

The Authors consider the forensic implications regarding the transmission of HIV to the orthodontic patient. First of all, the lesions of the oral cavity that require immediate diagnosis with foremost importance given to hygiene and prevention are examined. Secondly, the subject is considered of professional liability for virus transmission due to the physicians malpractice, particularly focussing on the possible fault, type of damage and cause-effect relationship. Sanctions are considered in detail regarding virus seropositivity and occurrence of symptomatology in the different phases of the disease, thus leading to a brief outline of possible refunding guidelines. Particular emphasis is placed on the evaluation of the causal relationship, underlying the difficulty related to establishing a clear cut cause-effect relationship.

[Experimental chronic poisoning by mercury and alcohol: histopathologic, ultrastructural findings and toxicologic and enzymatic evaluations]. / Intossicazione cronica sperimentale da mercurio ed alcool: reperti istopatologici, ultrastrutturali e dosaggi tossicologici ed enzimatici.

Rats were treated with HgCl2 and/or alcohol per os in a standard diet as to get a chronic intoxication. Histological and ultrastructural examination of the liver, GPT, GOT, LDH enzymatic activities, and toxicological mercury evaluation were performed. Liver cell degenerative changes with focal necrosis, and structural alteration and fibrosis were demonstrated in the group of rats treated with HgCl2. The combined administration of HgCl2 and alcohol did not result in more advanced lesions, even if steatosis could be demonstrated in the liver. An increase of the GPT, GOT and LDH enzymatic activities was demonstrated in the rats of both groups but it was higher in the rats treated with HgCl2 and alcohol combined. On the contrary, the liver and kidney mercury storage was higher in the rats treated with HgCl2 alone.
