Although the whole globe is stopped dead due to this pandemic, the world of crime is still rising with several crimes and people are still victimized and killed due to suicide, homicide, or accident. Forensic practitioners, mainly in the field of clinical-forensic medicine have to investigate those suspicious or sudden unexpected deaths, including deaths due to infection of COVID-19 via autopsy to expose the cause(s) of death. These forensic pathologists are facing many challenges and a great risk of potential infection during postmortem examination as that deceased body may be infected with COVID-19. This pandemic has led to medical malpractice and a reduced number of proper complete autopsies, which could draw a veil over the criminal offenses and conceal a truth behind death, led to a miscarriage of justice. Autopsies were ignored in most deaths during the pandemic as an exception following COVID-19 guidelines. This article enlights various medicolegal issues, risks, and challenges caused during autopsy due to this pandemic situation and also provide insights for protective bio-safety guidelines for a forensic death investigation</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1475 An Overview of Forensic Voltammetric Analysis of New Psychoactive Substances 2021-03-16T12:38:38+03:00 Ketan Patil Ketan Patil forensicsketan@gmail.com Astha Pandey astha.pandey@gfsu.edu.in <p>New Psychoactive Substances (NPS) are synthetic drugs that create similar effects as various narcotic drugs and psychotropic substances. Different NPS such as mephedrone, synthacaine, synthetic cannabinoids, etc. are available today which are sold using numerous platforms like drug markets, head shops, dark webs, etc. They are emerging rapidly and becoming popular in society because of their variable nature and easy to escape from the law. Consequently, their analysis is extremely crucial in the prohibition of drug abuse and the development of laboratory methods. This review introduces a broad overview of the analysis of various new psychoactive substances by voltammetric techniques such as cyclic voltammetry, differential pulse voltammetry, square wave voltammetry, stripping voltammetry, etc. It also focuses on various methodologies that were developed for the detection of these NPS which play a leading role in forensic investigation by providing a rapid, sensitive, and cost-effective platform of analysis. The need for the advancement of varied methods and analysis of more drugs is additionally discussed.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1466 1,2-Indanedione (IND) Reagent for Detection of Latent Fingermarks: A Review 2021-03-29T08:46:16+03:00 Sachil Kumar skumar@nauss.edu.sa Devidas Sudam Bhagat dsbhagat999@gmail.com Gurvinder Singh Bumbrah bumbrah85@gmail.com <p>1,2-Indanedione (IND) is a chemical method for the detection of latent fingermarks on dry, porous surfaces such as paper, cardboard etc. It is an amino acid sensitive fluorescent reagent for developing latent fingermarks. The method is based on interaction of IND with amino acid fraction of latent fingermarks. The method develops clear, stable, pink (also known as Joullie pink) colored fingerprints which are fluorescent in nature. It is an efficient and non-destructive procedure for developing latent fingermarks on wide range of surfaces of forensic importance. Standardized testing of IND formulation is suggested to improve the eficiency of this reagent to develop latent fingermarks on wide range of surfaces of forensic importance.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1459 Differentiation of high velocity ammunition type from GSR metal element originating from different firearm: a Pilot Study 2021-03-28T13:22:40+03:00 ABHIJITSINH PARMAR abhiparmar57@gmail.com <p>The examination of GSR collected from the scene of occurrence is critical to the forensic science community because it provides answers to problems such as distinguishing between entry and exit wounds, estimating the range of fire, and linking an individual to the use of a firearm. Insufficient information exists on the differentiation of ammunition type through the analysis of GSR. This study investigated the potential of differentiating between ammunition types through the analysis of its metallic residue using energy dispersive x-ray fluorescence spectroscopy. Three firearms (AK-47 assault rifle, Self-loading rifle, and Carbine rifle) were adopted for the study. Overall, a series of 6 shots were performed from each firearm at a muzzle-target angle of 0˚ (perpendicular to the target surface).The residues were subjected to a non-destructive analysis by energy dispersive X-Ray fluorescence (EDXRF-7000, Shimadzu) without sample preparation. Gunshot residues originating from 9mm Carbine, AK-47 and Self-loading rifle produced common metal element including P, K, Cu, Ti, and Zn. Considering that, analysis of the sample residue was carried out EDXRF, it was unreliable to predict the ammunition type from the particles that originated from the firearm-ammunition employed.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1461 An Experimental Setup to manually determine the Pen Pressure of any Author for forensic comparisons using mathematical relations 2021-03-14T10:10:31+03:00 Nidhi Sagarwal nidhi.11816304@lpu.in Mohit Soni mohit.24385@lpu.co.in <p>Pen pressure is an individual characteristic of every author. It is near decisive in determining authorship. However, it has been observed that there is no established method for calculation of this individualistic value. This paper proposes an experimental setup to manually calculate the pen pressure of an author using a simple mathematical relation between speed and pressure which considers the displacement on a writing surface with respect to time. The proposed relation can be utilized to derive the value of stress applied by the author on a given writing surface. This value can be quantified and utilised for automatic author identification systems of the future as well. The proposed methodology employs no electronic sensors, expensive experimental setups or specially designed hardware for calculation. Yet it consistently delivers a numerical distinction for every author.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1458 Forensic dental age estimation of North Indian children using three radiological scoring methods 2021-03-02T14:23:23+03:00 Deeksha Sankhyan deeksha.sankhyan@gmail.com <p><em>Background</em>: Dental age estimations, although believed to be reliable in children, have reportedly shown variations in their accuracy levels indicating regional differences. Present study aims to study the error thresholds of Nolla, Demirjian and Willems methods for age estimation of North Indian children.</p> <p><em>Method and Results</em>: Digital orthopantomograms of 168 children aged 3-15 years were analyzed for the three methods. Demirjian dental age was found to be closest to the mean chronological age as indicated by the p-value of paired t-test. The error range for Willems and Demirijian methods was ±5 years with 87.5% cases showing error within the range of ±2 years and it was ±6 years with 84.5% cases with error within ±2 years using Nolla method. Mean absolute error for Nolla, Demirjian and Willems methods was 1.09, 1.10 and 0.97 years, respectively.</p> <p><em>Conclusion</em> Willems method was better suited for dental age estimation of studied population, though none of the methods precisely estimated age of the participants. Wide variations in age estimates of varied population groups may be due to differences in statistical methods or population aspects. Thus, comparison of the methods for different populations by the same researcher is suggested to reduce certain biasness in the study.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1455 Ethics in medical research – An Indian Perspective 2021-02-25T19:37:02+03:00 Sami Ullah yadavprave@gmail.com <p>Ethics represents a universal code describing one’s character-an established state of the soul in different situations that require great acumen. Failure to address the ethical issues in a coherent and logically scientific manner received a host of criticism from various institutions including the non-stakes. However, in absence of clear and broadly out reached recommendations and laws concerning the use of fixed human tissues for secondary research-oriented aims, it is possible that objectionable and unethical practices might well (if not always) compromise the patient/individual autonomy. This manuscript might have never been executed had we not confronted with unnecessary queries while applying for ethical clearance of the project, which includes leftover surplus histopathological tissues for other research aims. Although with regard to the issue, the Indian Council of Medical Research (ICMR) document proposes waiving of consent provided no direct contact is established between the researcher and the donor. The core issues concerning research on the acquired surplus human tissues (archived tissues) are insufficient as well as unclear. Pertinently, the restrictions on secondary use of biological samples and data after the completion of a particular study is a cause of concern as the leftover material(s) is made unavailable for additional research. The paradigm of informed consent should therefore, be specific and sufficiently informative regarding risks, all the usual uses of the collected samples, future research on the left over surplus human bio-banking materials, benefits to participants, benefits to society at large, ownership rights and withdrawal from participation along with its consequences.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1449 Allele Diversity, Haplotype Frequency, Haplotype Diversity and Forensic Genotyping of Fulanis and Yorubas resident in Ilorin, Kwara State, North Central of Nigeria 2021-03-02T09:29:37+03:00 Adelaja Akinlolu adelaja.akinlolu.454@my.csun.edu Nabila Sule akinlolu.aa@unilorin.edu.ng Maryam Muhammed akinlolu.aa@unilorin.edu.ng David Oyedepo akinlolu.aa@unilorin.edu.ng Maryam Olawole akinlolu.aa@unilorin.edu.ng Mercy Adejumo akinlolu.aa@unilorin.edu.ng Yusuf Anigilaje akinlolu.aa@unilorin.edu.ng Moshood Yusuf akinlolu.aa@unilorin.edu.ng Precious Omole akinlolu.aa@unilorin.edu.ng Temiloluwa Bukoye akinlolu.aa@unilorin.edu.ng Tomilayo Olatunji akinlolu.aa@unilorin.edu.ng Samuel Shodiya akinlolu.aa@unilorin.edu.ng Rahman Bolarinwa rbolarin@oauife.edu.ng <p>Nigeria is the most populous African nation comprising of over 250 ethnic groups.

It is a major cause of morbidity and mortality after formation of DVT. Few case reports and case series of massage-related adverse events are mentioned in the literature. This case illustrates the occurrence of PE in which ended fatally in a man who develop sudden bilateral calf pain who resorted to ayurvedic treatment.</p> <p><strong>Case History:</strong></p> <p>A 38-year-old recently married man developed bilateral calf pain of one-week duration. After seeking treatment initially from a general practitioner, he decided to resort to ayurvedic treatment later. Calf massaging was done, and the victim collapses soon after massaging. He was confirmed dead on arrival at the hospital. Autopsy revealed massive pulmonary embolism and presence of DVT in calf muscles.</p> <p><strong>Conclusions:</strong></p> <p>A major deterrent to effective prevention and treatment of VTE is a general lack of awareness. Prolonged period of inactivity is a known factor that promote formation of deep vein thrombosis. He has a history of standing for prolonged periods of time and probably massaging resulted in dislodging the thrombus causing PE.</p> <p>However available data is not sufficient to arrive at a conclusion on association of PE with act of massaging.

The post-assessment test was taken after one month, and the result was analyzed.It has been observed that social media apps like WhatsApp could be effective in teaching-learning methods for creating awareness on certain topics.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1417 A Case of Death Following Postoperative Rhabdomyolysis 2021-01-03T14:06:53+03:00 Hind ABOUZAHIR abouzahirhind@gmail.com <p><strong>Background</strong>: Postoperative rhabdomyolysis is a well-known complication, especially after prolonged surgery. There are few published reports of rhabdomyolysis following ear surgery. This phenomenon of massive muscle necrosis can produce secondary acute renal failure. The risk factors have to be managed carefully during anesthetic management. We report a case male patient who developed rhabdomyolysis precipitated acute kidney injury after Reconstructive ear surgery.</p> <p><strong>Case presentation</strong>: A patient in his fourteen underwent a prolonged surgery of 08 hours and 30 minutes for repairing his amputated right ear under general anesthesia. The patient’s postoperative course was complicated by rhabdomyolysis manifested by elevated levels of serum creatine phosphokinase (100000 IU/l). Subsequently, the patient developed secondary acute renal failure necessitating hemodialysis, but at that point, he had an unrecovered cardiac arrest which led to his death. The linkage between surgical positioning, prolonged surgery time, and rhabdomyolysis is discussed.</p> <p><strong>Conclusion: </strong>Prolonged duration of surgery is a well-recognized risk factor in the development of rhabdomyolysis. Early recognition of rhabdomyolysis induced acute kidney injury is important in reducing the postoperative morbidity and mortality in patients. A protocol based approach could be applied for early recognition and management.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1416 Fatal Fall from height and Self Inflicted Wounds-A Case of Complex Unplanned Suicide. 2021-02-17T14:44:48+03:00 DINESH RAO drraoforensic@yahoo.com <p>A 32-year-old man Jumped to Death in his Multistoried Apartment.

It starts functioning at about 10th week of fetal life and plays vital role in tissue metabolism and general growth and development. It secretes three hormones T3, T4 and Thyrocalcitonin.&nbsp;<strong>Aims &amp; objective:</strong> To study association of the changes in the weight and morphology of thyroid gland in suicidal and non suicidal cases.&nbsp;<strong>Material and methods:</strong> In this prospective study, thyroid glands were collected from dead bodies brought for medico-legal autopsies to the department of Forensic Medicine and Toxicology from Dec. 2015 to Sep. 2017. After removal, the weight was recorded, and then the gland was preserved and fixation done in 10 % formalin for more than 2 weeks. After 2 weeks, grossing was done and slides were prepared and studied.&nbsp;<strong>Results:</strong> In study group cases, maximum weight of thyroid gland was 27.6 grams and minimum was 18.5 grams. In control group cases, maximum weight was 26.5 grams and minimum was 18.7 grams. The mean weight of the thyroid gland in the suicidal group was 22.21 grams and the standard deviation was 2.21 grams. Of 50 study cases, 15 (30%) revealed significant pathological findings and the rest 35 (70%) were histologically normal (Fig.6). 14 of these cases (28%) revealed focal lymphocytic thyroiditis (FLT) and only 1 case (2%) showed nodular goitre (NG).&nbsp;</p> <p>&nbsp;</p> <p><strong>Keywords:</strong> Thyroid gland, suicide, weight, depression, lymphocytic thyroiditis</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1411 IDENTIFICATION OF CITES-LISTED Euphorbia royleana THROUGH DNA BARCODING TECHNOLOGY: A NEW FACET IN WILDILDLIFE FORENSICS 2021-02-17T14:29:10+03:00 Tina Sharma sharmatina1989@gmail.com Mukesh K Thakar mukeshk38@gmail.com <p>Disorganized and chaotic collections of&nbsp;<em>Euphorbia&nbsp;</em>plant species from the wild resources is one of the major reason of its endangered status.

The study concludes that the Algerian and Saudi legislators took a positive stance by approving the criminal protection of the trademark and imposing deterrent penalties according to which they achieve the purpose of the punishment.

Males below the age of 20 years (48 %) were highly vulnerable. Education status revealed that most of the patients have an education level below O/L representing 52 % (Ordinary Level/ O/L is similar to the General Certificate of Secondary Education/ GCSE in Cambridge Education System in United Kingdom) and the majority were married (52%). Scalds were seen in 52 %, while flame burns in 28 % cases. Most of the incidents had taken place at home (92%). Burn injuries were most frequently observed on upper extremities (47 %) and the majority were of first degree in nature. Furthermore, this study revealed that 57 % recovered without any complications, while 34 % resulted in scarring or disfigurement. <br />It was highlighted that children are the most vulnerable to in sustaining burns, especially with hot water in domestic settings. The study recommends increasing awareness among parents/guardians regarding safe handling of hot water to minimize such incidents.</p> 2020-10-29T00:00:00+03:00 Copyright (c) 2020 Arab Journal of Forensic Sciences & Forensic Medicine https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1358 Succession of Dipteran Fly Maggots on Poisoned Pig Cadavers at Nnamdi Azikiwe University, Awka, Nigeria 2020-11-10T12:12:06+03:00 Maduamaka C.

Due to the limited quantity and intricate nature of samples, there is a need for fast, sensitive and reliable techniques for the effective analysis of this vital evidence. In the current study, an attempt is made to study the feasibility of ATR FT-IR in combination with chemometric tools for chemical characterization and species differentiation of grass stains. <br />Ten different grass species belonging to three subfamilies, Panicoideae, Chlorodoidae, and Bambusoideae, were collected and analyzed by using the ATR FT-IR spectroscopy combined with the PLSR chemometric tool. <br />Results showed a clear difference between samples of Panicoideae, Chlorodoidae, and Bambusoideae subfamilies, and between species of each subfamily. To analyse the performance of the classification model, a set of 10 unknown/blind samples (unknown to the analyst) were randomly selected from the training dataset and all unknown/blind samples were accurately assigned in their corresponding group. <br />ATR FT-IR spectroscopy requires minimal sample preparation and can be successfully used as an eco-friendly, non-destructive, and reliable alternative to other existing methods.</p> 2020-11-05T00:00:00+03:00 Copyright (c) 2020 Arab Journal of Forensic Sciences & Forensic Medicine https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1355 Potential and Accuracy of Hand Length and Hand Breadth in Sex Determination: An Insight into Hausa Population of Nigeria 2020-11-10T11:12:47+03:00 Magaji G.

However, it is suggested that every population needs anthropological reference data. The objectives of this study were to determine the potential and accuracy of hand length and hand breadth in sex determination among the Hausa population of Nigeria. <br />Random sampling was employed to select 204 male and 194 female subjects aged 18-30 years. Hand length and hand breadth were measured using standard protocols. Two-sample t-test, binary logistic regression, receiver operating characteristics curve, and Youden’s index were used for determining sex using hand dimensions. Posterior probability and likelihood ratio were used to determine the favor odds of each category of hand dimension in sex discrimination.<br />A significant sexual dimorphism was observed in hand length and hand breadth with higher mean values in males. The variance of sex explained by hand parameters ranges from 38.50/51.35% (lower/upper limits) to 52.98/70.66%, which were exhibited by right hand length and left hand breadth respectively. The overall prediction and percentage accuracy of sex discrimination ranges between 80.40 to 86.70 % that were exhibited by right hand length and handbreadth respectively. We observed that left hand breadth exhibited higher Younden’s index with an area under curve (AUC) ranging from 91.60% to 96.05%. We found that hand length of &gt; 189.99 mm was indicative of male origin and hand breadth of &gt; 79.99 mm was indicative of male origin. <br /><br /></p> 2020-09-07T00:00:00+03:00 Copyright (c) 2020 Arab Journal of Forensic Sciences & Forensic Medicine https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1354 Description of Rare Genetic Variants Discovered with Promega PowerPlex® Forensic Amplification Kits during STR analysis of Routine Paternity and Kinship Cases 2020-11-10T10:57:41+03:00 Hanan K.

Alnima mislam@nauss.edu.sa <p>Short Tandem Repeats (STR) have been widely used to create a discriminating DNA profile during the forensic investigation of a crime. The Paternity and Kinship Division at Medico-legal Directorate (MLD)/ Baghdad, provides a DNA fingerprinting service for paternity and kinship requests from different courts of law and police departments from across the country. Several rare variants were observed during DNA analysis such as rare off-ladder alleles, tri-allelic pattern as well as allele dropout. Variants that have been transmitted among family members were investigated in this study.<br />During the period between 2008 to 2019, 38309 samples have been analyzed in the Paternity and Kinship Laboratories for DNA profiling to resolve the referred cases. DNA profiles found to have unusual STR patterns (off-ladder, tri-allelic pattern, inter-loci variable were analyzed and documented).<br />A total of 17 variants were observed which were as shared among family members. Rare off-ladder alleles (9 cases + inter-loci variant 2 cases), as well as 6 cases of tri-allelic patterns were recorded. <br />The presence of each type of these variants among family members proves that these variations are of genetic origin. They also represent rare genetic variants specific to the Iraqi populations that could be used for the establishment of a new Iraqi DNA database, which might be useful for genealogical studies as well as in terms of resolving familial, social, and moral disputes.</p> 2020-09-07T00:00:00+03:00 Copyright (c) 2020 Arab Journal of Forensic Sciences & Forensic Medicine https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1353 Frequency of Mamelons in Relation to Age, Gender and Occlusion among the Saudi Population 2020-11-10T10:47:09+03:00 Munther Alalowi mislam@nauss.edu.sa Nouf Al-Jhany mislam@nauss.edu.sa <table width="907"> <tbody> <tr> <td width="708"> <p>This observational study aimed to determine the prevalence and identify the presence of mamelons while simultaneously correlating the age, gender, and bite relationship of the subjects.</p> <p>Total sample size included 518 patients, both males and females.

The study of Post-Mortem changes is important as they can help an investigator to determine the time since death &amp; the cause of death. The aim of this review is to discuss the process of decomposition and their various stages, the contributing factors that affect decomposition and understand the various classes of organisms ranging from Flies to Vertebrate Scavengers that can help estimate the time since death and the degree of decomposition. Moreover, the review talks about methods for estimation of Post-Mortem Interval and related complications. This detailed review is all about the phenomena’s that are involved after death and its contributing factors and can be utilized as a reference for future studies. This article also seeks to determine how efficient is it to estimate the PMI and what are its limitations.</p> Copyright (c) https://journals.nauss.edu.sa/index.php/AJFSFM/article/view/1349 Juvenile Terrorism in India 2021-01-05T09:12:21+03:00 Yaseen MG psy.myyaseen@gmail.com <p><em>Objectives</em>: Perpetrators of terrorist offence often tend to be young children under the age of 18years. They are found engaged in a terrorist activity in different capacity. Terrorist groups often involve such children directly into terrorist act. Available literature has shown that children are more vulnerable than adults in the violent terrorist act owing to the lack of maturity and judgmental capacity. They are also found to have low level of guilt due to under arousal of autonomic nervous system activity. <em>Methods</em> : In the present study 30 juvenile terrorist were brought to Forensic Science Laboratory, Bangalore from different parts of the country i.e Maharashtra, Karnataka and Andhra Pradesh. They were subjected to polygraph examination to measure changes in physiological parameters related to crime under investigation. <em>Results and Conclusion</em> : Factors such as the age, education, family background, socio economic status, addictions were found to be having influence on the lower arousal of autonomic nervous system. The need of the hour is to identify the causes of juvenile terrorism and to create a reformative environment for the adolescent who conflicts with the law. In the present study, an attempt has made to explore psycho physiological factors underlying juvenile terrorism.</p> <p><strong>Keywords: <em>Forensic Psychology, Psychophysiology, Juvenile terrorist, , Polygraph,&nbsp; ANS , </em></strong></p> Copyright (c)
