Abstract
Electrocution is a leading cause of unnatural deaths, especially in industrial and developing regions like India. In a recent case, an individual was brought in for autopsy following an apparent accidental electrocution. Strikingly, the postmortem examination revealed no typical entry or exit wounds associated with electric shocks. The body exhibited rigor mortis and a unique sign: reddish froth draining from the nasal cavities. Internal examination unveiled distinctive findings. Multiple tiny hemorrhages were observed over the heart's left ventricle, while the heart's blood vessels and valves remained unobstructed. In contrast, the lungs showed a frothy, whitish-red appearance extending into the bronchioles. This case presents an unprecedented observation: the presence of froth in the respiratory tract during electrocution. This case underscores the need for thorough autopsies. Even when specific indicators are absent, it highlights the importance of considering electrocution when froth is found in the respiratory tract. Such cases remind forensic pathologists of the diverse and occasionally unexpected manifestations they may encounter, encouraging the exploration of new phenomena within forensic medicine.

Abstract
The pubic symphyseal surface is one of the reliable parameters used to estimate age, as it consistently shows degenerative observational variations throughout the lifespan, particularly from the 3rd decade onwards. These changes have been extensively studied to generate population-specific models for forensic age estimation. In the past, there have been many studies used to estimate age at death from the pubis symphysis using skeletal remains. However, due to dearth of contemporary skeletal repositories, and the resource intensive maceration process required for obtaining examination quality bones, studies on cadaver are difficult to conduct. Moreover, due to recent advancements in the science of medical imaging, newer radiological modalities like computed tomography (CT) can be used to visualize previously inaccessible areas such as the pubic symphysis in cadavers and the living alike, and subsequent age estimation is feasible. Recently, Chen et al. (2008, 2011) conducted a study on the cadaveric Chinese Han population in both males and females separately by using nine morphological changes and scoring them according to the changes that occurred. The present study aimed to estimate an individual's age using CT images of the pubic symphysis, by applying the scoring method for its morphological changes given by Chen et al. The present study was conducted on 263 randomly selected participants (Males = 154, Females = 109), who came for diagnostic purposes to the hospital. The CT images of these individuals were collected after obtaining ethical approval and proper consent from the study participants. Each of the morphological indicators was assessed, and appropriate scores were given according to criteria given by Chen et al. In the present study, both linear and multiple regression models to estimate age using the pubic symphyseal morphological changes were developed. From the results of the present study, it was concluded that the Chen et al. scoring method can be used to accurately estimate age from 3DCT images of the living, and the models derived in the present study could be applicable to individuals from the Indian subcontinent.

Abstract
Cases involving electrocution burns are tough to investigate for the clinical forensic practitioner. Burns from high-voltage electrocution might seem like burns from other sources, especially if the victim is in an unconscious state. In this situation, circumstantial evidence in addition to clinical symptoms may be used to exclude other burns. Furthermore, the investigation of accident site results to aid in explaining the pattern of injuries discovered during a clinical evaluation. In this case study, we reported a case of a 33-year-old male who came in contact with a high-voltage transmission wire and was burned over both hands and lower back region. The exit wound was atypical in appearance, with a scorched area of peeling blistering skin, charring, and severe scorching over the lower back region which were correlated with the accident site, and the circumstances that led to electrocution injury.

Abstract
A primary objective of a medico-legal autopsy is to determine the identity of the deceased. The act of praying for prolonged periods of time can lead to the development of skin marks in Muslims, commonly referred to as "Naamaj signs" or prayer marks. An elderly male of unknown identity was brought dead to the hospital, where a post-mortem examination was performed. The patient's name in the treatment records suggested that the deceased was a member of the non-Muslim community, conflicting with the post-mortem examination report indicating circumcision and belonging to the Muslim Community. The disposal authority questioned whether cremation or burial was more suitable for the deceased. When it comes to cases involving religious identification, basing a decision on a single feature alone is not enough to permit the disposal of a deceased body. It is crucial to take into account other characteristics before determining the appropriate disposal method.

Abstract
Postmortem interval (PMI) in legal medicine is extremely important for both criminal and civil cases, and several sorts of techniques have been recommended. This systematic review solely focuses on approaches linked to RNA analysis, instead of including all proposed methods for determining the PMI. The term PMI will be used in this review to indicate the time between a person's death and the postmortem examination of the body. We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines when conducting this systematic review. The majority of studies on various tissues at various time intervals at various temperatures are non-human, and just a small number are on humans. The results are then provided using various statistical approaches. To calculate the PMI, post-mortem RNA degradation was examined using several tissues. The result so obtained had an opposite polarity. While some studies show that RNA stability in various tissues remained constant for several days after death, the other group of studies showed evident RNA degradation over time post-mortem, which was significantly influenced by temperature and other agonal factors. These factors have an impact on the multi-parametric mathematical model of ante and post-mortem factors on RNA degradation, as well as its applicability and feasibility. The estimation of PMI using RNA degradation can prove to be highly objective and efficient after controlling for the various factors and challenges that pose the estimation of RNA in forensic samples difficult.

Abstract
Artifacts are pervasive in every realm of biological science, and this includes the field of medicine. Unless explicitly recognized by scientific experts, artifacts can be found and may influence research and findings in the medical domain, just as they do in other branches of biological science. Therapeutic artifacts are changes that occur in the body as a result of medical interventions. These artifacts can sometimes pose challenges in forensic investigations, as they may be misinterpreted or mistaken for signs of trauma or foul play. This case series presents three cases illustrating different types of treatment artifacts encountered in forensic medicine. These three cases highlight the importance of considering medical interventions and therapies when interpreting autopsy findings. It is crucial for forensic experts to have a comprehensive understanding of therapeutic artifacts to accurately differentiate them from genuine injuries or pathologies. By recognizing and properly interpreting these artifacts, forensic investigations can be conducted with increased accuracy and ensure that justice is served.

Abstract
BACKGROUND Age estimation is a critical aspect of human identification. Age is assessed using cranial suture obliteration, pelvic morphological changes, epiphyseal fusion of long bones, dental maturation, and other standard methods. METHODS The present study investigated three-dimensional (3D) computed tomography (CT) scans of 263 individuals (183 males and 80 females) to assess the extent of ectocranial suture closure. The assessment of obliteration was done using a three-stage scoring method. Spearman's correlation coefficient (p < 0.05) was calculated to assess the relationship between cranial suture closure and chronological age. Simple and multiple linear regression models were developed using the cranial suture obliteration scores to estimate age. RESULTS The standard errors of the estimate using multiple linear regression models developed for estimating age using obliteration scores of sagittal, coronal, and lambdoid sutures were 15.08 years in males, 13.27 years in females, and 14.74 years in the total study population. CONCLUSION This study concludes that in the absence of additional skeletal age markers, this method can be used alone or in conjunction with other well-established methods of age assessment.

Abstract
INTRODUCTION Euthanasia or mercy killing has remained as a matter of extensive debate and ethical conflicts in the scientific literature. Discussions on this theme have got legal, religious, political and philosophical ramifications. AIM OF THE STUDY The present study aimed to assess the knowledge, attitude and practices of medical professionals in a tertiary care hospital. METHODS After taking prior approval from the institutional ethics committee a structured questionnaire was prepared and distributed among 200 consenting medical professionals in a tertiary care centre in the North-Western region of India. RESULTS 50% of the respondents said that they were sure of the existing regulation on euthanasia in India. When gender differences were considered a significant difference (p=0.0147) was found between the two sexes regarding the alternate decision maker for deciding euthanasia. It was observed that there was a significant difference(p=0.0055) between those with the age more than 30 years and aged less than 30 years regarding the type of euthanasia that is justifiable. DISCUSSION In the present study, the percentage of doctors favouring euthanasia is higher than compared in previous studies. The view of euthanasia is highly variable in different studies. Even though passive euthanasia has been legalised recently, there is an apprehension that it might be misused.

Abstract
In legal medicine, the determination of post-mortem interval (PMI) is not only an important but also one of the most difficult aspects. Several methods are used to estimate PMI such as physicochemical, entomological, biochemical, metabolic, autolytic, and physical methods. These methods provide a wide range of PMI as they are affected by different factors. The approach behind the present study is to calculate an accurate PMI by using mRNA degradation and fold change expression (FCE) of cardiac-specific genes viz. N-terminal pro-B-type natriuretic peptide (NPPB) and cardiac troponin I (TNNI3). Seventeen cadaver heart tissues were analysed within a time frame of up to 12 hours from the time since death, at different time intervals at room temperature. Gene expression was determined and the data were analysed using the value of average delta Ct (ΔCt) value of the assessed gene and housekeeping gene. Delta delta Ct (ΔΔCt) method was used to calculate the FCE at the different 7-time groups. The FCE of TNNI3 was almost stable till 15 hours of PMI and then after 15 hours, expression shows a decrease up to 24 hours after death; whereas, NPPB shows that FCE was stable till 12 hours of PMI and then after 12 hours, expression shows a decrease up to 24 hours after death. The FCE of NPPB and TNNI3 was almost stable till 12 hours. Thus, the estimation of PMI by analysis of the FCE of cardiac-specific genes can be a new promising method in forensic medicine.

Abstract
In cranial autopsies, the post-mortem examination requires the use of a saw for the removal of the skull cap. In these procedures, sawing of bone becomes a critical source of infectious aerosols which spread instantaneously in the immediate environment, generating liquid aerosols including droplets of cerebrospinal fluid and blood, and leading to exposure of all autopsy personnel. In high-risk cases like prion disease, tuberculosis, severe acute respiratory syndrome (SARS), COVID-19, etc. where the skull would require sawing, the prime concern is the saw operator's exposure to these pathogens. Therefore, the author suggests the use of an ingenious ergonomic semi-circular craniotomy box during skull cap and brain removal in the autopsy procedure to successfully prevent the contamination of the entire autopsy hall. A transparent acrylic plastic box has been customized, which is semi-circular in shape having three walls, one semi-circular dome without a floor, a front wall with adjustable zipper closure, and a hind wall with circular holes with sleeves made of 5-layer fabrics. The dome contains one outlet for a vacuum suction pipe on the side, two holes on each side of the dome with non-woven fabric arms for the saw operator, and assistants' arms for performing skull opening procedures. The use of this box allowed the author to prevent and limit the spread of the generation of infectious aerosols in the autopsy hall as the bone dust collected in the vacuum ensures the safety of autopsy surgeons.

Abstract
Growth Differentiation Factor-15 (GDF-15), though emerged as a novel marker in gynecological cancers, is yet to be recognized in clinical diagnostics. Eligible studies were sorted from multiple online databases, namely PubMed, Cochrane, ClinicalTrials.gov, Google Scholar, Web of Science, Embase, Scopus, LILACS, Opengrey. From six studies, histopathologically diagnosed cases without prior treatment, and with diagnostic accuracy data for GDF-15 in gynecological cancers, were included. Our meta-analysis shows that GDF-15 has pooled diagnostic odds ratio of 12.74 at 80.5% sensitivity and 74.1% specificity, and an AUC of 0.84. Hence, GDF-15 is a potential marker to differentiate gynecological malignancy from non-malignant tumors.

Abstract
The estimation of accurate post mortem interval (PMI) is a crucial question in forensic medicine. Several approaches have been used to determine the PMI including physical, metabolic, autolytic, entomological, physiochemical and biochemical methods over time. For estimation of PMI, RNA degradation after death is reported to be an important tool. This study aimed to analyse the pattern of gene expression by serial estimation of cardiac specific cardiac troponin I (cTnI) gene and autophagy gene HMGB1 for determining PMI at room temperature by using housekeeping gene GAPDH. Right ventricular heart tissue weighing 10 g was collected and harvested from 17 medico-legal autopsies. The tissue was homogenized in phosphate-buffered saline (PBS) on ice. Further, homogenate of cardiac tissue was analysed by quantitative Real time polymerase chain reaction (qRtPCR) for gene amplification and gene expression of cTnI, HMGB1 gene and GAPDH, at different time intervals (0,6,12 h) at room temperature. The result revealed ∆Ct value of cTnI gene of the cardiac muscle showing almost equal degradation at equal time interval correlated with PMI within 0-12 h at room temperature, and the ∆Ct value of HMGB1 degraded to half in every subsequent 6-hour interval at room temperature. In conclusion, the estimation of PMI by analysis of serial estimation of gene expression is a decent new tool in forensic medicine. The study shows an equal degradation of cTnI gene at equal time interval and HMGB1 degrades to half at six-hour interval. Therefore, these can be useful for estimation for PMI.

Abstract
AIM To investigate and compare the cytotoxicity and bioactivity of CMCR agents on stem cells derived from exfoliated deciduous teeth. METHODOLOGY MTT assay, flow cytometry, Alizarin Red staining and scratch assay were used to assess the cellular viability, apoptosis, calcium matrix deposits and cell migration, respectively. The gene expression of ALP and BMP-2 was measured with RT-PCR. One-way ANOVA and Bonferroni post-test was used for statistical analysis. RESULTS 0.5% Carisolv showed highest cell proliferation and calcium matrix formation, whereas 0.5% Papacarie reported the highest% live cells and cell migration. The highest mRNA expression of ALP and BMP-2 was reported in SHEDs cultured in 0.5% Papacarie (after 72 h incubation) and 0.5% Carisolv (after 24 h incubation), respectively. CONCLUSION CMCR agents are biocompatible and bioactive when cultured in stem cells derived from exfoliated primary teeth.

Abstract
Corrosive digestive tract injuries are considered to be a source of morbidity and mortality worldwide. The cases of acid ingestion in Forensic Medicine practice are not infrequent. Corrosive ingestion usually presents with injuries over the face, oropharynx, esophagus, and gastrointestinal tract. We report a case of a 65-year-old woman who was brought to the emergency department with a history of ingestion of toilet cleaner at her home. Following this, she developed blackish-brown discoloration over the abdomen. The patient survived for less than one day. An autopsy confirmed the perforation of the stomach and small intestine. 500 ml of blackish fluid was present in the peritoneal cavity which resulted in corrosive peritonitis. The chemical examiner's report showed corrosive mixtures comprising sulfate, nitrate, and chloride ions in the peritoneal contents. This case report highlights atypical cutaneous presentation over the abdomen following corrosive acid ingestion, which has not been reported previously. The possible explanation for this cutaneous manifestation was corrosive effects of the underlying viscera due to its close proximation to the abdominal wall and presence of minimal intra-abdominal fat. A direct physical connection between perforation and cutaneous findings was not identified. The case emphasizes the need for a comprehensive approach in managing such cases, analyzing ingested material, and following standard autopsy protocols in case of death.

Abstract
Forensic medicine has, for a long time, been relying on biochemical, anthropologic, and histopathologic evidences in solving various investigations. However, depending on the method used, lengthy sample processing time, scanty sample, and less sensitivity and accuracy pervade these procedures. Accordingly, newer arenas such as the thanatomicrobiome have come forward to aid in its quandaries; furthermore, the parallel advances in genomic and proteomic techniques have complemented and are still emerging to be used in forensic experiments and investigations. Postmortem interval (PMI) is one of the most important aspects of medico-legal investigations. The current trend in PMI estimation is toward genomic analyses of autopsy samples. Similarly, determination of cause of death, although a domain of medical sciences, is being targeted as the next level of forensic casework. With the current trend in laboratory sciences moving to the discovery of newer disease-specific markers for diagnostic and prognostic purposes, the same is being explored for the determination of the cause of death by using techniques such as Real-Time PCR, DNA micro-array, to Next-Gen Sequencing. Establishing an individual’s biological profile has been done using medicolegal methods and anthropology as well as bar-bodies/Davidson bodies (gender determination); and in cases where the determination of age/gender is a challenge using morphological characteristics; the recent advances in the field of genomics and proteomics have played a significant role, e.g., use of mitochondrial DNA in age estimation and in maternity disputes. The major hurdle forensic medical research faces is the fact that most of the studies are conducted in animal models, which are often difficult to mimic in human and real-time scenarios. Additionally, the high accuracy required in criminal investigations to be used in a court of law as evidence has prevented these results to come out of the labs and be used to the optimum. The current review aims at giving a comprehensive and critical account of the various molecular biology techniques including “thanatogenomics,” currently being utilized in the veritable fields of forensic medicine.

Abstract
Sinonasal Undifferentiated carcinoma (SNUC) comprises 3% of the head and neck tumors, including metastatic neoplasms. Herein we report the case of a 60-year-old male who was brought dead to our institute with previous records of a contrast-enhanced CT scan of the brain and MRI with evidence of tumor in the maxillary sinus with intracranial extensions. The histopathological examination of the mass in the maxillary sinus proved to be SNUC with metastases to the brain, lungs, and around the aorta. These tumors are undifferentiated and are distinct from other poorly differentiated tumors in deriving their origin from the Schneiderian epithelium. The aggressive nature of the tumor renders the prognosis quite dismal. SNUCs need to be early recognized and distinguished from other poorly differentiated carcinomas with the help of immunohistochemistry.

Abstract
Coronavirus disease 2019 (COVID-19), which causes severe acute respiratory syndrome and lung failure, is caused by the novel coronavirus, also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to high transmission rates from individual to individual, it has progressed to a pandemic. However, indirect transmission from inanimate objects or surfaces that have come in contact with a patient poses an even more significant threat as it is difficult to trace the source of infection in these cases. Therefore, these surfaces and objects require disinfection with chemicals having potent viricidal activity. These include alcohols, aldehydes, quaternary ammonium compounds, chlorhexidine, and chlorine-based disinfectants, among others. They vary in their viricidal activity depending on their structure, concentrations, and mechanism of action. Several studies have looked into these agents and the transmission of the virus related to it. Moreover, certain viricides, if used as constituents of commercially available oral disinfectants, can further aid in preventing ventilator-associated pneumonia and maintain oral hygiene. However, these chemicals are not entirely free of potential hazards. In this review, we have compiled and critically appraised some commonly used viricidal agents in healthcare settings and the role they can play in the prevention of SARS-CoV-2 transmission.

Abstract
Telemedicine was considered futuristic and experimental some years ago, but it is a reality today. It is now emerging as an important tool for convenient as well as specialized healthcare, particularly for patients in remote locations with limited access to standardized healthcare services. However, there are multiple challenges to realizing its full potential. We focus on some key medicolegal and ethical issues such as doctor-patient relationship, informed consent, rights of the patient, malpractice, and principles of confidentiality relevant to the practice of telemedicine and virtual consultation. We explore the global as well as the Indian legal perspective pertaining to the application of telemedicine. The absence of specific laws for registration and practice of telemedicine and virtual consul-tation in India acts as a deterrent for medical practitioners to engage in its potential use. Hence, there is a need for specific legislation.

Abstract
Background and study aims Although newer needle designs are thought to improve diagnostic outcomes of endoscopic ultrasound-guided fine-needle biopsy, there is limited evidence on their diagnostic performance. The aim of this meta-analysis was to provide a pooled estimate of the diagnostic performance and safety profile of Franseen and Fork-tip fine-needle biopsy needles. Patients and methods Computerized bibliographic search on the main databases was performed through March 2019. The primary endpoint was sample adequacy. Secondary outcomes were diagnostic accuracy, optimal histological core procurement, mean number of needle passes, pooled specificity and sensitivity. Safety data were also analyzed. Results Twenty-four studies with 6641 patients were included and pancreas was the prevalent location of sampled lesions. Overall sample adequacy with the two newer needles was 94.8 % (93.1 % - 96.4 %), with superiority of Franseen needle over Fork-tip (96.1 % versus 92.4 %, P < 0.001). Sample adequacy in targeting pancreatic masses was 95.6% and both needles produced results superior to fine-needle aspiration (FNA) (odds ratio 4.29, 1.49 - 12.35 and 1.79, 1.01 - 3.19 with Franseen and Fork-tip needle, respectively). The rate of histological core procurement was 92.5%, whereas diagnostic accuracy and sensitivity were 95 % and 92.8 %, again with no difference between the two needles. Number of needle passes was significantly lower in comparison to FNA (mean difference: -0.42 with Franseen and -1.60 with Fork-tip needle). No significant adverse events were registered. Conclusion Our meta-analysis speaks in favor of use of newer biopsy needles as a safe and effective tool in endoscopic ultrasound-guided tissue acquisition.

Abstract
Dyadic suicides may be committed simultaneously or one after another by two or more people who may or may not have made a prior pact. The perpetrator is usually male and their victims female, and generally their intimate partners, with children less commonly involved. Another distinct type of homicide-suicide is the killing of children by a parent (filicide-suicide). The terms 'maternal filicide' or 'paternal filicide' are used respectively when the perpetrator is the mother or the father of the victim. We report a rare case of maternal filicide, where the mother drowned her three children and then herself in the same water tank. The case highlights the extreme stress put on a mother of girls in a patriarchal society where there is an overriding expectation and wish for sons. The resulting pressure on this mother for her 'failure' caused her to take her own and her children's lives.

Abstract
Identification of the dead is significant in examination of unknown, decomposed and mutilated human remains. Establishing the biological profile is the central issue in such a scenario, and stature estimation remains one of the important criteria in this regard. The present study was undertaken to estimate stature from different parts of the sternum. A sample of 100 sterna was obtained from individuals during the medicolegal autopsies. Length of the deceased and various measurements of the sternum were measured. Student's t-test was performed to find the sex differences in stature and sternal measurements included in the study. Correlation between stature and sternal measurements were analysed using Karl Pearson's correlation, and linear and quadratic regression models were derived. All the measurements were found to be significantly larger in males than females. Stature correlated best with the combined length of sternum, among males (R = 0.894), females (R = 0.859), and for the total sample (R = 0.891). The study showed that the models derived for stature estimation from combined length of sternum are likely to give the most accurate estimates of stature in forensic case work when compared to manubrium and mesosternum. Accuracy of stature estimation further increased with quadratic models derived for the mesosternum among males and combined length of sternum among males and females when compared to linear regression models. Future studies in different geographical locations and a larger sample size are proposed to confirm the study observations.

Abstract
The legal and moral validity of euthanasia has been questioned in different situations. In India, the status of euthanasia is no different. It was the Aruna Ramachandra Shanbaug case that got significant public attention and led the Supreme Court of India to initiate detailed deliberations on the long ignored issue of euthanasia. Realising the importance of this issue and considering the ongoing and pending litigation before the different courts in this regard, the Ministry of Health and Family Welfare, Government of India issued a public notice on May 2016 that invited opinions from the citizens and the concerned stakeholders on the proposed draft bill entitled The Medical Treatment of Terminally Ill Patients (Protection of Patients and Medical Practitioners) Bill. Globally, only a few countries have legislation with discreet and unambiguous guidelines on euthanasia. The ongoing developments have raised a hope of India getting a discreet law on euthanasia in the future.

Abstract
The elongation or calcification of the stylohyoid ligament that leads to pressure symptoms, or entrapment of nearby glossopharyngeal nerve or carotid artery, is known as Eagle syndrome. A PubMed search leads to finding of rare fatality among the 49 reported cases. In the present case, the deceased was a 40-year-old male who choked on his food. We hypothesise that the impaction of food in the upper respiratory tract, as well as the inability to intubate the person, were both the result of the calcified stylohyoid ligament.

Abstract
AIM A preliminary study of coronaries using post-mortem angiography was undertaken to see the prevalence of atherosclerotic coronary stenosis in non-cardiac unnatural deaths. MATERIALS AND METHODS This study was conducted in a tertiary care centre located in Chandigarh. A total of 128 medico-legal cases were studied comprising 88 males and 40 females. Post-mortem examinations of these MLC cases were conducted in the Department of Forensic Medicine, PGIMER, Chandigarh. All hearts were visually screened by post-mortem coronary angiography first and then grossly examined using serial transverse incision technique in positive screening cases to find the degree of narrowing. RESULTS Of the study group, 34% males and 20% females showed evidence of narrowing on angiography. Of the males showing coronary stenosis, 83% had single vessel disease and 13% had double vessel disease, while only one individual had triple vessel disease. In cases of female, all the cases of coronary stenosis were single vessel disease. Left anterior descending coronary artery (LAD) was the most common vessel involved, followed by right coronary artery (RCA) & Left circumflex artery (LCX) and in cases of double vessel disease, LAD in combination with LCX was responsible for 75% of the cases. Remarkably 23.6% of study population in the age group of less than 40 years showed appreciable narrowing in at least one of the coronaries. CONCLUSION In general, the prevalence of CAD is on the rise, particularly in younger population owing to the changes in their lifestyle and food habits. This preliminary study revealed evidence of narrowing of at least one coronary in 34% male and 20% female population and 23.6% subjects were less than 40 years old. Further detailed studies are needed especially in younger age group and to support the need for preventive cardiology in the early years of life.
