An immunohistochemical study in a fatality due to ovarian hyperstimulation syndrome

Congenital heart diseases (CHDs) and forensic investigations: Searching for the cause of death

Congenital Heart Diseases (CHDs) are a group of structural abnormalities or defects of the heart that are present at birth. CHDs could be connected to sudden death (SD), defined by the WHO (World Health Organization) as "death occurring within 24 h after the onset of the symptoms" in an apparently "healthy" subject. These conditions can range from relatively mild defects to severe, life-threatening anomalies. The prevalence of CHDs varies across populations, but they affect millions of individuals worldwide. This article aims to discuss the post-mortem investigation of death related to CHDs, exploring the forensic approach, current methodologies, challenges, and potential advancements in this challenging field. A further goal of this article is to provide a guide for understanding these complex diseases, highlighting the pivotal role of autopsy, histopathology, and genetic investigations in defining the cause of death, and providing evidence about the translational use of autopsy reports. Forensic investigations play a crucial role in understanding the complexities of CHDs and determining the cause of death accurately. Through collaboration between medical professionals and forensic experts, meticulous examinations, and analysis of evidence, valuable insights can be gained. These insights not only provide closure to the families affected but also contribute to the prevention of future tragedies.

New Trends in Immunohistochemical Methods to Estimate the Time since Death: A Review

The identification of a reliable and accurate post-mortem interval (PMI) is a major challenge in the field of forensic sciences and criminal investigation. Several laboratory techniques have recently been developed that offer a better contribution to the estimation of PMI, in addition to the traditional physical or physico-chemical (body cooling, lividity, radiocarbon dating, rigor mortis), chemical (autolysis), microbiological (putrefaction), entomological, as well as botanical parameters. Molecular biology (degradation pattern of macromolecules such as proteins, DNA, RNA), biochemical analysis of biological fluids (such as blood, cerebrospinal fluid, and vitreous humor), and immunohistochemistry are some of the most recent technological innovations. A systematic review of the literature was performed with the aim of presenting an up-to-date overview on the correlation between the immunohistochemical (IHC) expression of specific antigenic markers at different PMIs. The systematic review was performed according to PRISMA guidelines. Scopus and PubMed were used as search engines from January 1, 1998 to March 1, 2022 to evaluate the effectiveness of immunohistochemistry in estimating PMI. The following keywords were used: (immunohistochemical) OR (immunohistochemistry) AND (time since death) OR (post-mortem interval) OR (PMI). A total of 6571 articles were collected. Ultimately, 16 studies were included in this review. The results of this systematic review highlighted that IHC techniques, in association with traditional methods, add, in Bayesian terms, additional information to define a more accurate time of death and PMI. However, current IHC results are numerically limited and more data and studies are desirable in the near future.

Pharmacogenetics and Forensic Toxicology: A New Step towards a Multidisciplinary Approach

Pharmacogenetics analyzes the individual behavior of DNA genes after the administration of a drug. Pharmacogenetic research has been implemented in recent years thanks to the improvement in genome sequencing techniques and molecular genetics. In addition to medical purposes, pharmacogenetics can constitute an important tool for clarifying the interpretation of toxicological data in post-mortem examinations, sometimes crucial for determining the cause and modality of death. The purpose of this systematic literature review is not only to raise awareness among the forensic community concerning pharmacogenetics, but also to provide a workflow for forensic toxicologists to follow in cases of unknown causes of death related to drug use/abuse. The scientific community is called on to work hard in order to supply evidence in forensic practice, demonstrating that this investigation could become an essential tool both in civil and forensic contexts. The following keywords were used for the search engine: (pharmacogenetics) AND (forensic toxicology); (pharmacogenetics) AND (post-mortem); (pharmacogenetics) AND (forensic science); and (pharmacogenetics) AND (autopsy). A total of 125 articles were collected. Of these, 29 articles were included in this systematic review. A total of 75% of the included studies were original articles (n = 21) and 25% were case reports (n = 7). A total of 78% (n = 22) of the studies involved deceased people for whom a complete autopsy was performed, while 22% (n = 6) involved people in good health who were given a drug with a subsequent pharmacogenetic study. The most studied drugs were opioids (codeine, morphine, and methadone), followed by antidepressants (tricyclic antidepressants and venlafaxine). Furthermore, all studies highlighted the importance of a pharmacogenetics study in drug-related deaths, especially in cases of non-overdose of drugs of abuse. This study highlights the importance of forensic pharmacogenetics, a field of toxicology still not fully understood, which is of great help in cases of sudden death, deaths from overdose, deaths after the administration of a drug, and also in cases of complaint of medical malpractice.

Forensic Post-Mortem Investigation in AAS Abusers: Investigative Diagnostic Protocol. A Systematic Review

Anabolic–androgenic steroids (AASs) are a group of synthetic molecules derived from testosterone and its precursors. AASs are widely used illicitly by adolescents and athletes, especially by bodybuilders; AASs are among the most used drugs for improving physical performance, as well as for aesthetic purposes. The use of AASs by professional and recreational athletes is increasing worldwide. This review focused on deaths related to AAS abuse and to investigation of the autopsy results and histopathological findings using a rigorous methodology protocol covering: a complete autopsy, histological analysis, and a broad toxicological investigation. Moreover, we aimed to define an investigative diagnostic protocol supporting forensic pathologists during the post-mortem investigation of AAS abusers. This review was conducted using PubMed Central and Google Scholar databases to find articles published between 1 January 1968 and 30 June 2021, using the following key terms: “(anabolic-androgenic steroids) AND (autopsy); (anabolic-androgenic steroids) AND (forensic)”. A total of 939 articles were screened and 926 did not meet the inclusion criteria. In conclusion, 14 articles were included in this systematic review, reporting 137 fatal cases of AAS abuse in total. The histopathologic studies showed myocardial damage characterized by myocyte hypertrophy, focal myocyte damage with myofibrillar loss, interstitial fibrosis, mostly subepicardial, and small vessel disease. Indeed, in AAS-related cases, autopsy plays a pivotal role in the study of AAS adverse effects and organ damage related to their use or abuse. This systematic review aimed to define a specific workflow in death cases related to AASs, suggesting important future insights to better clarify sudden deaths related to AASs, such as the use of miRNAs. The forensic community needs a unified approach in cases of suspected death related to the use of AASs. There are several occasions to apply this workflow, for example in cases of death of bodybuilders and of young people who die in gymnasiums or during sports activities.

Effects of a Plastic-Free Lifestyle on Urinary Bisphenol A Levels in School-Aged Children of Southern Italy: A Pilot Study

Bisphenol A (BPA) is an endocrine disruptor (ED) frequently used in food packaging. BPA is used as a monomer in the manufacture of some food packaging. This study aimed to evaluate the urinary BPA concentration in an Italian pediatric cohort, testing the levels of this ED over a period of 6 months, evaluating the effects of a diet regimen with a reduction of Plastic Food Packaging (PFP). One hundred thirty Italian children were enrolled and divided into two groups "School Canteen" and "No School Canteen." The first group consumed one meal at school using a plastic-free service for 5 days/weeks, while the other group did not modify their normal meal-time habits. The BPA levels were tested in urine samples at three time points: T0, is the time before the application of the plastic-free regimen diet; T3, 3 months later; and T6, 6 months later. A reduction of urine BPA levels was detected in the "School Canteen" group. In particular, the reduction was significant analyzing both the intra (among the three testing times) group and inter (between "School Canteen" and "No School Canteen") group variability. Our results show the effects of a diet regimen with a reduction of PFP, demonstrating a connection between urinary BPA levels and food packaging.

Adverse Effects of Anabolic-Androgenic Steroids: A Literature Review

Anabolic-androgenic steroids (AASs) are a large group of molecules including endogenously produced androgens, such as testosterone, as well as synthetically manufactured derivatives. AAS use is widespread due to their ability to improve muscle growth for aesthetic purposes and athletes’ performance, minimizing androgenic effects. AAS use is very popular and 1–3% of US inhabitants have been estimated to be AAS users. However, AASs have side effects, involving all organs, tissues and body functions, especially long-term toxicity involving the cardiovascular system and the reproductive system, thereby, their abuse is considered a public health issue. The aim of the proposed review is to highlight the most recent evidence regarding the mechanisms of action of AASs and their unwanted effects on organs and lifestyle, as well as suggesting that AAS misuse and abuse lead to adverse effects in all body tissues and organs. Oxidative stress, apoptosis, and protein synthesis alteration are common mechanisms involved in AAS-related damage in the whole body. The cardiovascular system and the reproductive system are the most frequently involved apparatuses. Epidemiology as well as the molecular and pathological mechanisms involved in the neuropsychiatric side-effects of AAS abuse are still unclear, further research is needed in this field. In addition, diagnostically reliable tests for AAS abuse should be standardized. In this regard, to prevent the use of AASs, public health measures in all settings are crucial. These measures consist of improved knowledge among healthcare workers, proper doping screening tests, educational interventions, and updated legislation.

Nandrolone Decanoate: Use, Abuse and Side Effects

Background and Objectives: Androgens play a significant role in the development of male reproductive organs. The clinical use of synthetic testosterone derivatives, such as nandrolone, is focused on maximizing the anabolic effects and minimizing the androgenic ones. Class II anabolic androgenic steroids (AAS), including nandrolone, are rapidly becoming a widespread group of drugs used both clinically and illicitly. The illicit use of AAS is diffused among adolescent and bodybuilders because of their anabolic proprieties and their capacity to increase tolerance to exercise. This systematic review aims to focus on side effects related to illicit AAS abuse, evaluating the scientific literature in order to underline the most frequent side effects on AAS abusers’ bodies. Materials and Methods: A systematic review of the scientific literature was performed using the PubMed database and the keywords “nandrolone decanoate”. The inclusion criteria for articles or abstracts were English language and the presence of the following words: “abuse” or “adverse effects”. After applying the exclusion and inclusion criteria, from a total of 766 articles, only 148 were considered eligible for the study. Results: The most reported adverse effects (found in more than 5% of the studies) were endocrine effects (18 studies, 42%), such as virilization, gynecomastia, hormonal disorders, dyslipidemia, genital alterations, and infertility; cardiovascular dysfunctions (six studies, 14%) such as vascular damage, coagulation disorders, and arteriosus hypertension; skin disorders (five studies, 12%) such as pricking, acne, and skin spots; psychiatric and mood disorders (four studies, 9%) such as aggressiveness, sleep disorders and anxiety; musculoskeletal disorders (two studies, 5%), excretory disorders (two studies, 5%), and gastrointestinal disorders (two studies, 5%). Conclusions: Based on the result of our study, the most common adverse effects secondary to the abuse of nandrolone decanoate (ND) involve the endocrine, cardiovascular, skin, and psychiatric systems. These data could prove useful to healthcare professionals in both sports and clinical settings.

Sudden Cardiac Death in Anabolic-Androgenic Steroid Users: A Literature Review

Background and objectives: Anabolic-androgenic steroids (AASs) are a group of synthetic molecules derived from testosterone and its related precursors. AASs are widely used illicitly by adolescents and athletes, especially by bodybuilders, both for aesthetic uses and as performance enhancers to increase muscle growth and lean body mass. When used illicitly they can damage health and cause disorders affecting several functions. Sudden cardiac death (SCD) is the most common medical cause of death in athletes. SCD in athletes has also been associated with the use of performance-enhancing drugs. This review aimed to focus on deaths related to AAS abuse to investigate the cardiac pathophysiological mechanism that underlies this type of death, which still needs to be fully investigated. Materials and Methods: This review was conducted using PubMed Central and Google Scholar databases, until 21 July 2020, using the following key terms: “((Sudden cardiac death) OR (Sudden death)) AND ((androgenic anabolic steroid) OR (androgenic anabolic steroids) OR (anabolic-androgenic steroids) OR (anabolic-androgenic steroid))”. Thirteen articles met the inclusion and exclusion criteria, for a total of 33 reported cases. Results: Of the 33 cases, 31 (93.9%) were males while only 2 (61%) were females. Mean age was 29.79 and, among sportsmen, the most represented sports activity was bodybuilding. In all cases there was a history of AAS abuse or a physical phenotype suggesting AAS use; the total usage period was unspecified in most cases. In 24 cases the results of the toxicological analysis were reported. The most detected AASs were nandrolone, testosterone, and stanozolol. The most frequently reported macroscopic alterations were cardiomegaly and left ventricular hypertrophy, while the histological alterations were foci of fibrosis and necrosis of the myocardial tissue. Conclusions: Four principal mechanisms responsible for SCD have been proposed in AAS abusers: the atherogenic model, the thrombosis model, the model of vasospasm induced by the release of nitric oxide, and the direct myocardial injury model. Hypertrophy, fibrosis, and necrosis represent a substrate for arrhythmias, especially when combined with exercise. Indeed, AAS use has been shown to change physiological cardiac remodeling of athletes to pathophysiological cardiac hypertrophy with an increased risk of life-threatening arrhythmias.

Analysis of a New Work-Related Stress Assessment Tool

Background:

Work-related stress is a relevant phenomenon in terms of health and safety at work, as occupational distress has a negative impact on individual and organisational well-being. It is a complex and multifactorial phenomenon, whose evaluation must be carried out through a specific and adequate methodology.

Objective:

This work aims to identify versatile tools that can quickly provide reliable measures of work distress. It analyzes the proposal elaborated by the “Comitato Unico di Garanzia per le Pari Opportunità, la Valorizzazione del Benessere di chi lavora e contro le Discriminazioni” of Rome, i.e. the tool “Valutazione è prevenzione, Sicurezza è partecipazione”.

Methods:

A study was carried out on a sample of 474 employees of the Neapolitan Judicial Offices, who were given a standardized questionnaire to investigate the stress, associated with the proposal of the Comitato Unico di Garanzia.

Results:

From the elaboration of the results, it emerges that the conditions of working wellbeing are linked to two main factors related to the perception of workers both of physical-environmental and organisational-relational aspects. In particular, it emerged that the new assessment tool, consisting of a small number of items, contributes to the detection of work stress, so it is necessary to deepen through future research the contribution that this tool can offer to the survey on work-related stress.

Conclusion:

Having highlighted two factors that significantly saturate the presence of a working discomfort, through an agile tool, allows us to plan a new research path, which can approach the complexity of the phenomenon through the methods of deep learning.

Oligosypthomatic ovarian hyperstimulation syndrome in a spontaneous uneventful pregnancy. A case report

Spontaneous hyperstimulation syndrome (spOHSS) is a rare event in pregnancies following natural conception. Only a few cases are reported in the scientific literature and result associated with massive ovarian enlargement with multiple cysts, dehydration, and fluid accumulation in the "third space". We report a novel case of spOHSS in a naturally conceived singleton pregnancy. The spOHSS was characterized by massive ovarian enlargement with multiple cysts. No dehydration and no signs of ascites were observed. The pregnancy uneventful evolved up to term.

Pregnancy Outcomes of In Vitro Fertilization with or without Ovarian Hyperstimulation Syndrome: A Retrospective Cohort Study in Chinese Patients

Background:

The effect of ovarian hyperstimulation syndrome (OHSS) on pregnancy outcomes of in vitro fertilization (IVF) patients is still ambiguous. This study aimed to analyze pregnancy outcomes of IVF with or without OHSS in Chinese patients.

Methods:

A retrospective cohort study was undertaken to compare pregnancy outcomes between 190 women with OHSS and 197 women without OHSS. We examined the rates of clinical pregnancy, multiple pregnancies, miscarriage, live birth, preterm delivery, preterm birth before 34 weeks’ gestation, cesarean delivery, low birth weight (LBW), and small-for-gestational age (SGA) between the two groups. Odds ratios (ORs) and 95% confidence intervals (CIs) of measure of clinical pregnancy were also analyzed.

Results:

The clinical pregnancy rate of OHSS patients was significantly higher than that of non-OHSS patients (91.8% vs. 43.5%, P < 0.001). After controlling for drug protocol and causes of infertility, the adjusted ORs of moderate OHSS and severe/critical OHSS for clinical pregnancy were 4.65 (95% CI, 1.86–11.61) and 5.83 (95% CI, 3.45–9.86), respectively. There were no significant differences in rates of multiple pregnancy (4.0% vs. 3.7%) and miscarriage (16.1% vs. 17.5%) between the two groups. With regard to ongoing clinical pregnancy, we also found no significant differences in the rates of live birth (82.1% vs. 78.8%), preterm delivery (20.9% vs. 17.5%), preterm birth before 34 weeks’ gestation (8.6% vs. 7.9%), cesarean delivery (84.9% vs. 66.3%), LBW (30.2% vs. 23.5%), and SGA (21.9% vs. 17.6%) between the two groups.

Conclusion:

OHSS, which occurs in the luteal phase or early pregnancy in IVF patients and represents abnormal transient hemodynamics, does not exert any obviously adverse effect on the subsequent pregnancy.

Fatal ovarian hyperstimulation syndrome in an anonymous egg donor

Ovarian hyperstimulation syndrome is a rare, but potentially life-threatening iatrogenic disorder arising from ovulation induction or ovarian hyperstimulation for assisted reproduction techniques. We report a case of a 26-year-old multiparous woman, an anonymous egg donor, who died a few hours after undergoing a procedure to donate eggs at an in vitro fertilization clinic. Her husband alleged that medical negligence had led to her death. The autopsy confirmed death due to ovarian hyperstimulation syndrome. We know of no previous descriptions of fatal ovarian hyperstimulation syndrome in an anonymous egg donor in medico-legal literature.

Predictors of Paracentesis in Women with Severe Ovarian Hyperstimulation Syndrome: A Retrospective Cohort Study

BACKGROUND

To identify predictors of paracentesis in women with severe ovarian hyperstimulation syndrome (OHSS).

METHODS

In a retrospective cohort study, we assessed patient characteristics and outcome measures of women with severe OHSS Golan grade II/III from 1996 to 2010 using univariate and multivariate analyses with the number of paracenteses as the main outcome.

RESULTS

Three hundred ninety four women with OHSS Golan grade II (n = 40) and grade III (n = 354) were included in the study. Paracentesis was performed in 108/394 (27%) of these women. One paracentesis was performed in 63 (16%), 2 paracenteses in 26 (6%), and ≥3 paracenteses 19 (5%) women, respectively. No thrombotic or cerebrovascular morbidity occurred. The mortality of the cohort was 0/394 (0%). In a univariate analysis, late onset OHSS (p = 0.02), pregnancy (p < 0.001), human chorionic gonadotropin use (p = 0.02), ovarian diameter (p = 0.006), and elevated serum levels of alanine aminotransferase (p < 0.001), hematocrit (p < 0.001), leucocytes (p < 0.001), thrombocytes (p < 0.001), and uric acid (p < 0.001) were associated with paracentesis. In a multivariate logistic regression analysis, only alanine aminotransferase (OR 1.006; 95% CI 1.001-1.01) and hematocrit (OR 1.16; 95% CI 1.05-1.27) were independently associated with paracentesis.

CONCLUSION

Alanine aminotransferase and hematocrit at initial presentation are independent predictors of paracentesis.

The European Court legitimates access of Italian couples to assisted reproductive techniques and to pre-implantation genetic diagnosis

On 28 August 2012, the European Court of Human Rights (ECHR) issued a judgment regarding the requirements for the legitimate access of couples to assisted reproductive techniques (ART) and to pre-implantation genetic diagnosis (PGD). This judgment concerns the case of an Italian couple who found out after their first child was born with cystic fibrosis that they were healthy carriers of the disease. When the woman became pregnant again in 2010 and underwent fetal screening, it was found that the unborn child also had cystic fibrosis, whereupon she had the pregnancy terminated on medical grounds. In order to have the embryo genetically screened prior to implantation under the procedure of PGD, the couple sought to use in vitro fertilisation to have another child. Since article 1 of the Italian law strictly limits access to ART to sterile/infertile couples or those in which the man has a sexually transmissible disease, the couple appealed to the European court, raising the question of the violation of articles 8 and 14 of the European Convention on Human Rights. The applicants lodged a complaint that they were not allowed legitimate access to ART and to PGD to select an embryo not affected by the disease. The European Court affirmed that the prohibition imposed by Italian law violated article 8 of the European Convention on Human Rights. Focusing on important regulatory and legal differences among EU Nations in providing ART treatments and PGD, we derived some important similarities and differences.

Two different entities of spontaneous ovarian hyperstimulation in a woman with FSH receptor mutation

Spontaneous ovarian hyperstimulation syndrome (OHSS) is an extremely rare event. Normally OHSS is seen in the context of IVF. In 2003 a mutation of the FSH receptor (FSHR D567N) was identified for the first time as a cause of spontaneous OHSS. In most FSHR mutations, a hypersensitivity to human chorionic gonadotrophin (HCG) or thyroid-stimulating hormone (TSH) is described. This clinical case presents for the first time two occurrences of spontaneous OHSS in a single woman with a FSHR mutation and two different entities. Pathophysiology of both pregnancies was completely different. During the first pregnancy, elevated HCG and androgen concentrations led to spontaneous OHSS and finally to miscarriage. The second pregnancy with spontaneous OHSS was dominated by a latent hypothyroidism and normal HCG concentrations and ended in a delivery of a healthy female newborn. Due to the unusual courses of the pregnancies, the study looked for a mutation in the FSHR and surprisingly identified the same mutation previously described. This report confirms for the first time the in-vitro findings in a single clinical case that TSH as well as HCG leads to spontaneous OHSS in patients with FSHR D567N mutation. Hypothyroidism has to be treated or ruled out.

Assisted reproductive technology: official data on the application of the Italian law

In 2004, the Italian parliament enacted Law 40/2004, which established new rules for assisted reproductive technology and included a very long and detailed list of restrictions. Since its enactment, the law has given rise to heated discussion at a national and international scientific level. In June 2007 a report presented to the Italian parliament published data from the National Institute of Health regarding the application of the law in 2005. From an overall comparison of data from the years 2003 (before Law 40/2004) and 2005, it emerges that the situation has been significantly altered by the application of this law. These data clearly demonstrate a drop in the percentage of pregnancies, and a consequent drop in the number of children born; a higher percentage of treatments that do not reach the transfer stage or that have a low possibility of success (non-elective embryo transfer); a decrease in the number of oocytes inseminated but an increase in the number of embryos transferred; a higher incidence of multiple births, with consequent immediate and future negative effects for the children and their mother; an increase in the number of pregnancies with a negative outcome.
