Triggering receptor expressed on myeloid cells-1 (TREM-1) is produced and up-regulated by exposure of myeloid cells to lipopolysaccharides or other components of either bacterial or fungal origin, ...which causes it to be strongly expressed on phagocytes that accumulate in inflamed areas. Because TREM-1 participates in septic shock and in amplifying the inflammatory response to bacterial and fungal infections, we believe it could be an immunohistochemical marker for postmortem diagnosis of sepsis. We tested the anti-TREM-1 antibody in 28 cases of death by septic shock and divided them into two groups. The diagnosis was made according to the criteria of the Surviving Sepsis Campaign. In all cases, blood cultures were positive. The first group was comprised subjects that presented high ante-mortem serum procalcitonin and the soluble form of TREM-1 (s-TREM-1) values. The second group comprised subjects in which s-TREM-1 was not measured ante-mortem. We used samples of brain, heart, lung, liver and kidney for each case to test the anti-TREM-1 antibody. A semiquantitative evaluation of the immunohistochemical findings was made. In lung samples, we found immunostaining in the cells of the monocyte line in 24 of 28 cases, which suggests that TREM-1 is produced principally by cells of the monocyte line. In liver tissue, we found low TREM-staining in the hepatocyte cytoplasm, duct epithelium, the portal-biliary space and blood vessel. In kidney tissue samples, we found the TREM-1 antibody immunostaining in glomeruli and renal tubules. We also found TREM-1 staining in the lumen of blood vessels. Immunohistochemical staining using the anti-TREM-1 antibody can be useful for postmortem diagnosis of sepsis.
Atypical compression of the neck may be classified as asphyxia in which the external compression on the cervical anatomical structures occurs in a peculiar manner. In such cases, death occurs due to ...the combination of several pathophysiological phenomena, such as respiratory, vascular, and nervous. When the mechanical action on the neck is violent and rapid, it is more correct to use the word percussion rather than compression. Usually there are no skin lesions of special significance in this type of neck percussion, unlike the cases of choking, strangulation, and hanging, and the diagnosis is challenging. It is important to carefully evaluate the body during the autopsy to identify which pathophysiological mechanism caused the death.
A young woman died immediately after being struck by a concrete beam at the level of her neck. The woman was on vacation with her boyfriend and decided to hang from a concrete beam suspended between two columns to take a souvenir photo when the beam suddenly broke and fell on her. The autopsy revealed multiple abrasions, swelling, and lacerations to the face, neck, and chest. Internal examination revealed primarily the presence of hemorrhagic infiltration in the anterior cervical compartments and lacerations of various organs, including the trachea.
Based on all the obtained data, including toxicological and histological, the cause of death was atypical ab extrinsic percussion of the neck, directed particularly at the right cervical neurovascular bundle.
In 2017, Italy passed a law that provides for a systematic discipline on informed consent, advance directives, and advance care planning. It ranges from decisions contextual to clinical necessity ...through the tool of consent/refusal to decisions anticipating future events through the tools of shared care planning and advance directives. Nothing is said in the law regarding the issue of physician assisted suicide. Following the DJ Fabo case, the Italian Constitutional Court declared the constitutional illegitimacy of article 580 of the criminal code in the part in which it does not exclude the punishment of those who facilitate the suicide when the decision has been freely and autonomously made by a person kept alive by life-support treatments and suffering from an irreversible pathology, the source of physical or psychological suffering that he/she considers intolerable, but fully capable of making free and conscious decisions. Such conditions and methods of execution must be verified by a public structure of the national health service, after consulting the territorially competent ethics committee. This statement admits, within strict and regulated bounds, physician assisted suicide, so widening the range of end-of-life decisions for Italian patients. Future application and critical topics will be called into question by the Italian legislator.
There has been a surge of interest in new technologies in medicine because of their promising clinical applications. Extensive research on additive manufacturing and its applications in the medical ...field has been carried out with good results and very high expectations. Due to their disruptive nature and potential, 3D printing and even more 3D bioprinting raise many ethical and safety concerns that need to be adequately addressed to provide good regulation before entering clinical practice. This article aims to highlight the general ethical concerns associated with the use of additive manufacturing in medicine and the lack of current international regulatory directives to guide these experiments. Transparency about how these new medical devices are regulated and approved is a fundamental requirement to promote and improve public trust, efficiency, safety and quality.
In modern times crossbow - a ranged weapon diffused during Middle Ages - is increasing its popularity in recreational hunting and sports; crossbow bolts have a great penetration capacity, despite ...their low initial velocity. Great concerns emerge when considering that notwithstanding crossbow is a potentially lethal distance weapon, it is easy to obtain without having to undertake any tests on the buyer's mental or physical health. Although rare, crossbow injuries can be challenging for the forensic pathologist due to great similarities with other wounds pattern (gunshots wounds or injury due to sharp force). Especially when the arrow is removed from its original position or the body is decomposed, identification of the weapon can be difficult. According to forensic literature, suicides, homicides and non-lethal injuries by crossbow have been reported up to the present day. We followed the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) indications in the identification and selection of studies and reviewed a series of cases of both fatal and non-fatal crossbow injuries, according to the manner of death (homicide, suicide, accidental). The casuistic part of this paper deals with an attempted murder of a 21-year old man: a case of non-lethal crossbow injury of the thorax in which an interdisciplinary approach, involving forensic inspection, ballistic and radiology tests, led to solve the case.
•Crossbow is a potentially lethal distance weapon, easy to obtain and to operate that not requiring practice so.•Crossbows have a great penetration capacity in soft tissues and bones, causing a wide range of lesions.•We described a case of attempted homicide, but literature reports cases homicide, accidental injuries and suicides.•A CT scan should always be performed both in dead and survived victims because can be of great help..
In the modern era, when prolonging life is not an option, the end-of-life discussions are unavoidably influenced by Neuroethics. Despite this, it is interestingly evident how the sentiments of a ...terminal patient of 1885 and a physician of 2020, are still comparable. This paper pre-sents the arguments behind the so-called "Therapeutic Misconception" and the aim of palliative care to provide dying patients support. It is essential to address priorities of informed consent, signed before any remedy is provided. A key component of the newest Neuroscience research is the analysis of motivation and free will. So, it is necessary to comprehend if the patient struggles to feel at peace with these aspects of his "right to die": Is he free to choose or is he influenced by the doctors? Is this confusion an example of "Therapeutic Misconception"? Is his Informed Consent totally "Informed"? In order to broaden our understanding, we account for many critical situations, such as the mentally impaired Psychiatric patients or the famous Italian case of Eluana Englaro. In addition, we suggested some current approaches such as Artificial Intelligence, useful in preserving some cognitive functions the patient may have lost. Furthermore, research in this field is very critical and in some Catholic countries like Italy, people faced difficulties accepting the idea of the "Anticipated directives". In general, whatever the mental status and whatever the terminal state, the patients seem still far from handling their own auto-determination and their Consent, even if the ultimate goal is to die with dignity.
ObjectivesTo summarise incidence and prevalence of diabetic ketoacidosis (DKA) in adults with type 1 diabetes (T1D) for the overall patient population and different subgroups (age, sex, geographical ...region, ethnicity and type of insulin administration).DesignSystematic literature review (SLR).Data sourcesMedline (via PubMed) and Embase (1 January 2000 to 23 June 2016).Study selectionPeer-reviewed observational studies with reported data on the incidence or prevalence of DKA in T1D adults were included. A single reviewer completed the study screening and selection process and a second reviewer performed an additional screening of approximately 20% of the publications; two reviewers independently conducted the quality assessment; the results were narratively synthesised.ResultsOut of 1082 articles, 19 met the inclusion and exclusion criteria, with two additional studies identified that did not specify the patient age range and are therefore not included in the SLR. Overall, eight studies reported incidence with a range of 0–56 per 1000 person-years (PYs), with one outlying study reporting an incidence of 263 per 1000 PYs. Eleven studies reported prevalence with a range of 0–128 per 1000 people. Prevalence of DKA decreased with increasing age. Subgroup analyses were performed using data from no more than two studies per subgroup. There was a higher prevalence of DKA reported in women, non-whites and patients treated with insulin injections compared with men, whites and patients using continuous subcutaneous insulin infusion pumps, respectively.ConclusionsTo our knowledge, this is the first SLR on the epidemiology of DKA in T1D adults. Despite an increasing prevalence of T1D in recent years, DKA in adults has been poorly characterised. In an era when the benefit–risk profiles of new antidiabetic therapies are being evaluated, including the potential risk of DKA, there is a clear need to better elucidate the expected rate of DKA among T1D adults.
Chronic venous insufficiency (CVI) and varicose veins (VVs) of the lower limbs are very frequent vascular diseases in Western countri-es. One possible complication of these conditions is skin ...ulceration and its consequent rupture, which can be spontaneous or due to mild or trivial trauma. In some cases, the resulting hemorrhage is fatal. When the victim is found dead, a large amount of blood around the body might lead to the hypothesis of violent death. The Forensic Pa-thologist needs to be very careful in the corpse's examination, in order to exclude any alternative cause of death. Herein, an illustrative case is reported, as well as a literature review of the literature concerning sudden hemorrhages from VVs. We found 27 scientific papers, the total reported cases of VVs rupture with profuse hemorrhages were 36, 32 of which were fatal. The main characteristics of such forensic scenario have been collected. Corpse examination of the victims showed pallor of the skin and mucous membranes, as well as marked pallor of organs as a sign of hemorrhagic shock, but these pathological findings are unspecific. Usually, the skin near the ulcer presented color alteration (discoloration and atrophy or pigmentation and hyperemia). Besides, the histological examination of the skin could be a valid instrument to demonstrate the presence of the ulcer, even if it could be very difficult to sample, because of its small size. An important limit of our study is the small number of collected cases. More studies in this field are needed to improve evidence concerning death due to VVs rupture.
Post Mortem Computed Tomography (PMCT) is being increasingly implemented in forensic field and could be an adjuvant to classic autopsies. In this study we evaluated the feasibility of complementation ...of conventional autopsy in trauma victims with PMCT.
A total of 21 subjects, who had sustained various types of blunt high-energy trauma, were selected from the casuistry of the Section of Legal Medicine at University of Pisa: before autopsy, a PMCT examination (Toshiba Aquilion 16 CT scanner) was performed, and after the acquisition of the raw images, MPR and VR reconstructions were performed with dedicated software.
PMCT is more sensitive than conventional autopsy in detecting skeletal injuries, whilst autopsy constitutes the method of choice for the detection of thoracic and abdominal visceral injuries.
PMCT should be considered a useful tool in addition to conventional autopsy in evaluating trauma victims: it detects further bone fractures in body parts difficult to investigate during autopsy (i.e. posterior regions), facilitating the pathologist in the reconstruction of events and in determining the cause of death.
Introduction
To assess the impact on hospitalization costs of multimodal analgesia (MMA), including intravenous acetaminophen (IV-APAP), versus IV opioid monotherapy for postoperative pain management ...in patients undergoing orthopedic surgery.
Methods
Utilizing the Truven Health MarketScan
®
Hospital Drug Database (HDD), patients undergoing total knee arthroplasty (TKA), total hip arthroplasty (THA), or surgical repair of hip fracture between 1/1/2011 and 8/31/2014 were separated into postoperative pain management groups: MMA with IV-APAP plus other IV analgesics (IV-APAP group) or an IV opioid monotherapy group. All patients could have received oral analgesics. Baseline characteristics and total hospitalization costs were compared. Additionally, an inverse probability treatment weighting IPTW with propensity scores analysis further assessed hospitalization cost differences.
Results
The IV-APAP group (
n
= 33,954) and IV opioid monotherapy group (
n
= 110,300) differed significantly (
P
< 0.0001) across baseline characteristics, though the differences may not have been clinically meaningful. Total hospitalization costs (mean ± standard deviation) were significantly lower for the IV-APAP group than the IV opioid monotherapy group (US$12,540 ± $9564 vs. $13,242 ± $35,825;
P
< 0.0001). Medical costs accounted for $701 of the $702 between-group difference. Pharmacy costs were similar between groups. Results of the IPTW-adjusted analysis further supported the statistically significant cost difference.
Conclusions
Patients undergoing orthopedic surgery who received MMA for postoperative pain management, including IV-APAP, had significantly lower total costs than patients who received IV opioid monotherapy. This difference was driven by medical costs; importantly, there was no difference in pharmacy costs. Generalizability of the results may be limited to patients admitted to hospitals similar to those included in HDD. Dosing could not be determined, so it was not possible to quantify utilization of IV-APAP or ascertain differences in opioid consumption between the 2 groups. This study did not account for healthcare utilization post-discharge.
