Rape is a heinous crime that can have devastating effects on the survivor, The immediate medical examination and treatment of a rape survivor are crucial for their well-being and to-gather the necessary evidence to strengthen the case. Proper evidence collection is important for a successful legal prosecution. The earlier a survivor arrives for evaluation in the emergency department, the greater the chance of obtaining critical forensic evidence such as DNA samples. When patients delay presentation, or shower and change their clothes, relevant microscopic and macroscopic evidence is often lost. Evidence collection, including injury documentation, becomes less fruitful as time passes and tissue heals. Medical documentation has been shown to be positively associated with filing of charges and conviction. A Retrospective analysis of 67 cases of sexual assault examined at Department of Forensic Medicine at SMS medical college from 1st Jan to 31st Oct, 2020 was done, The clinical findings of the survivors were correlated to the time duration elapsed between incidence and medico-legal examination for all cases. 15 out of 67 cases (22%) were reported within 72 hrs; out of which 9 (60%) cases had corroborative clinical findings, 45 (67%)cases, who had reported later than 7 days only 1 (2%) had corroborative clinical findings. delayed reporting is most common hurdle for corroboration of material evidence and alleged accusation in these cases, The correlation of time of examination and clinical findings, in the present study, questions the relevance of mandatory medical examination in all cases.

Handwritten signatures are unique behavioural attributes that serve as a distinct form of identification forindividuals. This study focuses on the analysis of signature patterns using various parameters, including aspect ratio, angle of the first letter with respect to the baseline, and the ratio of the area of a circle to its radius within the signature. A dataset consisting of 1200 genuine and 1200 simulated (English) signature samples from 12 individuals were examined using an image analysis tool to record measurements for these parameters. The primary objectives were to investigate the consistency of signatures within the same person and to compare genuine signatures with simulated ones. This study contributes to the field of forensic investigations by offering insights into the authentication of signatures and the measurement of dissimilarities between signatures of the same and different individuals based on their patterns. The findings aid in identifying most influential parameter in distinguishing genuine signatures from counterfeits and enhance the evidential value of handwritten signature samples. Additionally, the simplified approach employed in this study allows for universal applicability across languages. Future research endeavours could expand the dataset and explore additional parameters to further improve the accuracy and reliability of signature verification methods in forensic analysis.

Introduction: The term “suspected poisoning” describes the potential exposure of a human or animal to a poisonous chemical, which might result in a variety of symptoms ranging from minor symptoms to severe consequences. The kind and quantity of the poison implicated may affect the symptoms. If poisoning is suspected, it’s crucial to get help right away so that the correct toxin can be identified and the proper management can be given.Aim: To monitor the epidemiological traits and clinical trends of poisoning cases at the emergency department of Dr. RMLIMS Lucknow.Methods: All 295 instances of acute poisoning were reported to the emergency department between April 2022 to March 2023. It is retrospective observational research of 12 months duration carried out in a tertiary care hospital. Data on the patient’s age, gender, kind of poisoning, length of hospital stay, and result were gathered from hospital medical records and examined.Result: The majority of victims have married housewives with poor socioeconomic and educational standingwho were between the ages of 31 and 40. Agriculture poisons and domestic poisons were the two most often used toxins. Most of the time, the general health at the time of presentation was unstable.Conclusion: Suspected poisoning is a serious medical emergency that might have life-altering effects on thevictims. Knowledge of the probable causes and symptoms of poisoning is crucial to ensure prompt diagnosis and treatment. Those who have been exposed to harmful chemicals can recover and prevent long-term harm with the proper measures.

Sudden natural death accounts for significant portion of mortality. Autopsy is the only solution for finding the definite cause of sudden deaths. The aim of this study is to find out the causes of sudden natural death and to evaluate associated factors. Study comprise 64 cases of Sudden Death autopsies performed in Silchar Medical College during the period 1st May 2022 to 30th November 2022. The organs were retained for histopathological examination. Information gathered from available documents in departmental records. Inferences made after analyzing data. Out of 514 autopsies during the study period, 64 cases were sudden natural death. Male dominated over female victims. The maximum death occurred in the age group 40-50 years followed by 30-40 years. The cause of deaths in 39% were attributed to cardiac causes and the remaining were due to non-cardiac causes. Sudden unexpected death requires significant health concern as most death occurs in the age ranging from 30 to 50 years. Cardiac causes contribute the maximum and male population are mostly affected. This kind of death of adulthood affects the financial stability of whole family as well as the Society.

Forensic anthropology can play an important role in the identification process. Besides determination of race, sex and age of the unknown individual, estimation of stature enhances the reliability of identification. It is easier to get those data when the whole body or the entire skeleton isavailable to the forensic anthropologist. However incases of deliberate mutilation and disposal in parts, interference by wild animal and bomb blast by terrorist attack, recovery of the whole body or complete skeleton may not be possible. In those cases, in the forensic anthropologists have to give this opinion based upon the available supplied skeleton remains. Although approximate stature of the individual can be estimated from most of the long bones using either multiplication factors or regressionformulae, studies on estimation of stature from clavicle are limited. In the past, Terry, Oliver and Thieeme have tried to estimate the stature of the individual from clavicle. So the present study is planned to determine the stature from clavicle.

Soil is the loose surface material that covers land on which plants grow. It consists of a mixture of organic remains, clay, and rock particles, which gives it its uniqueness from place to place. Because of the uniqueness of soil, it has a high evidential value in the field of forensic science. In the present study, research has been conducted to check the range of variations in the soil collected from different crime-prone areas of Kottayam and Kollam districts of Kerala by physical, chemical, microscopic, and instrumental examination. In physical examination, soil colour, texture, consistency, and density were measured, and in chemical examination, pH and total soluble sulphate of the soil were measured. In instrumental examination, Heavy metal analysis was done by using Atomic Absorption Spectrometry (AAS), which helps to measure the amount of trace elements present in the soil. The study found that each soil has some significant variations that make it unique. In the field of forensic science, this can be highly helpful in determining the origin of soil by examining its colour, texture, structure, content, etc.

Background: Domestic violence is referred as shadow pandemic because it is seen globally. Domestic violence abuse is usually considered a problem that requires involvement of police or social services and not a problem that requires dental interference, but it is important to take under consideration that other services may even not be approached by the victim due to various reasons6. However, they may approach a dentist for facial trauma.Hence it is important to understand awareness, attitude and behaviour of dentists towards domestic violence victim patients.Materials and Methods: in this cross-sectional study, a self- administered, structured questionnaire was sent to dentists practicing in central India. Collected data were subjected to statistical analysis using Chi-square test, and P < 0.05 was considered statistically significant.Result: Mostly dentists were aware about and have heard about domestic violence in practice. As many as 37.6% dentist have encountered domestic violence victims in their practice but only 11.7% participants took any measures to record or report or refer DV victimsConclusion: As dental professionals are usually the first line of contact for patient with head and neck trauma,they would need to undergo special training to identify, support, and treat domestic violence patients.

Background: It is of great value to find time since death in the medicolegal investigations like serious crimes.Vitreous humor was more often used for the biochemical analysis as it is less contaminated or not affected by the putrefactive changes than other fluids of the body. It was stated by many researchers that potassium levels in the vitreous humour is more accurate in predicting time since death.Aim: The aim of the study is to assess the time since death using potassium level in the vitreous humorMethodology: This study includes 54 cases of victims brought to the tertiary care hospital based on inclusion and exclusion criteria. Cases with known time of death and with clear vitreous humor samples were included. Baseline characteristics like name, age, gender, exact time since death was collected. Vitreoushumor was collected through appropriate standardized technique. Sampling time was also noted. The collected data was entered in MS excel and analysis done in SPSS 23 software. P value <0.05 is considered to be significant.Results: Majority of the study participants belongs to 57-67 years of age group (28%) followed by 27-37 years of age (22%).Male predominance was observed in our study 41(76%). There is a linear correlation found between the vitreous potassium concentration and the postmortem interval (R2=0.907). The rate of the vitreous potassium increase was 0.36 meq/hr (Coefficient of regression =2.76 meq/l/hr)Conclusion: There is a linear relationship found between vitreous potassium concentration and time since death.Thus potassium in the vitreous can be used for assessing the time since death.
