Peer Assessment of Student Presentations: Key Takeaways and Lessons Learned.

Background Students' presentations are a teaching-learning tool where students not only study and understand a topic but also teach their peers, thereby learning the art and skill of effective presentation. Aims The study aimed to evaluate peer assessments in students' presentations and find their role and application in improving presentation skills among students through feedback and course correction. Methods A group of students every week from a class of 125 was assigned a topic to present to the rest of their batch students who evaluated their presentation on a rubric shared via a Google Form link. The number of students who gave responses was noted. The responses were also shared with the presenters. The evaluator faculty moderated and discussed the areas for possible improvement and course correction. The students also filled out a feedback form on the entire exercise after presentations from the entire batch. Results The quality of students' presentation skills improved with subsequent students over the period. The students learned about their areas of improvement. Through the feedback form, students shared their reasons not to give a presentation. However, most of them found the exercise beneficial. Conclusions Peer assessment can be a credible mode for improving presentation skills with the active participation of other students and provide a learning method based on others' performances. Peer responses provide for self-evaluation and self-reflection. This type of survey among different institutions will identify students' flaws, help them improve and self-evaluate, and add to the current literature.

Synergistic Manifestations in Cardiac Cysticercosis Complicated by Snake Bite: A Case Report and Literature Review.

Cysticercosis presents a prevalent issue on a global scale. Nevertheless, disseminated cysticercosis (DCC) is infrequent; even rarer is asymptomatic DCC. Here, we present a unique case of asymptomatic DCC involving the heart in a young male who came to medical attention following a fatal snake bite, ultimately leading to his demise. Despite the widespread dissemination of cysticercosis affecting multiple organs, the individual remained asymptomatic for the condition. We present a case of a 23-year-old male who was brought to the emergency department with a history of alleged snake bites. The patient was declared dead upon arrival at the All India Institute of Medical Sciences (AIIMS), Rishikesh, India. Autopsy findings revealed multiple significant cardiac abnormalities, including atheromatous changes with calcification in the root of the aorta and aortic valve, along with numerous collateral vessels originating from the left main coronary artery. Additionally, cystic nodules containing cysticercus larvae were identified within the myocardium, suggesting cardiac cysticercosis. The cause of death was determined to be complications related to the snakebite. This case emphasizes the importance of considering multiple potential etiologies in complex clinical presentations, especially in the tropics.

Morphometric Evaluation of Sutural Patterns at the Pterion and Asterion in Dry Indian Skulls: Surgical Relevance.

INTRODUCTION: The pterion and asterion serve as crucial landmarks on the skull, representing the antero-lateral and postero-lateral fontanelles in neonates, respectively. In clinical practice, these points play a pivotal role in guiding the understanding of deeper structures and their relationships to the head's surface. The thin calvarium at these junctures is susceptible to fractures, and the underlying vessels are prone to tear, often leading to extradural hematoma formation, necessitating burr hole surgery for evacuation. MATERIAL AND METHODS: The study involved 40 human dry skulls in Indians (n= 27 male (10.8%), n= 13 female (5.2%)) of unknown age, evaluating morphometric characteristics of 80 pterions and asterions. Measurements were conducted using a digital caliper (SKADIOO±0.2mm/0.01") in millimeters on both sides of each skull. The investigation also included an examination of sutural patterns in Pterion and asterion. RESULTS: Three types of sutural patterns were identified in the pterion, the most common being the sphenoparietal variety (75% on the right, 70% on the left), followed by the epipteric variety, which was the second most common (11.3% on the right, 12.5% on the left), and then the frontotemporal type (1.3% on the right, 2.5% on the left). Two sutural patterns were observed in the asterion: type 1 (presence of sutural bone) in 17.9% of skulls and type 2 (absence of sutural bone) in 82.1%. CONCLUSION: The differences in pterion and asterion positions across various populations explored in previous studies motivated us to conduct this research in the Indian population. Our findings revealed that among Indians, the predominant pterion type is predominantly sphenoparietal, whereas type 2 is the most prevalent in asterion. Understanding the clinical significance of the pterion and asterion is crucial for healthcare professionals to ensure precise and safe surgical procedures, particularly for the effective treatment of head trauma patients.

Challenges in Diagnosing Sudden Death Caused by Acute Hemorrhagic Pancreatitis: An Autopsy-Based Case Report.

Forensic pathologists frequently encounter cases of sudden natural death. Most sudden natural deaths are attributed to cardiac causes. Acute pancreatitis, especially hemorrhagic pancreatitis, is an infrequent yet critical contributor to sudden death. The role of a forensic pathologist is imperative in such cases to find out the cause of the sudden death and to either confirm or refute any allegations. In this context, we describe a case of a 34-year-old male who experienced sudden death due to acute hemorrhagic pancreatitis, highlighting the need for a detailed autopsy, pathophysiological insights, and diagnostic challenges.

Sudden Death Caused by Gastroesophageal Varices Rupture: Insights From an Autopsy-Based Case Series Unraveling the Pathological Events.

Sudden death is characterized by natural yet unexpected death, typically occurring within 24 hours from the onset of the patient's symptoms. While the majority of sudden deaths stem from cardiac issues/causes, there are instances where non-cardiac factors are at play. One such scenario involves hemorrhage from ruptured esophageal varices, a complication that stems from portal hypertension. Portal hypertension can manifest due to a range of pre-hepatic, hepatic, and post-hepatic conditions, with liver cirrhosis being the primary culprit. Although sudden death cases linked to the gastrointestinal system are relatively rare, the rupture of gastroesophageal varices, precipitating severe morbidity and a high mortality rate, represents a life-threatening condition. In this context, we present a case series encompassing five instances of sudden natural deaths arising from the rupture of gastroesophageal varices.

Quadriceps Angle Measurement in Adolescents With Short Stature: Exploring the Relationship Between Postural Alignment and Lower Limb Mechanics.

Background The quadriceps angle (Q angle) is measured as an angle formed by two lines that extend from the anterior superior iliac spine to the midpoint of the patella and from the midpoint of the patella to the tibial tuberosity. The average Q angle value for children aged between seven to 12 years was 13.1˚±3.5˚in boys and 13.7˚±4.9˚ in girls, whereas 8˚-15˚ in men and 12˚-19˚ in women. Abnormal variation in Q angle is associated with patellofemoral pain syndrome, lateral patellar malposition, dislocation, chondromalacia patella, patella alta, genu varum, etc. Methodology The present study explores the status of Q angle values among adolescents with short stature and their comparison with age and gender-matched children between 10 and 15 years of age. Results We found a statistically significant difference between the Q angle value in the control group and the male with short stature group aged 14-15 years, with a mean difference of 3.7˚. However, among females, there was a significant difference between the control group and the short-stature group aged 12-13 and 14-15 years, with a mean difference of 2.8˚ and 2.5˚, respectively. Implications Early detection and timely remedial measures, e.g., quadriceps strengthening exercises, before skeleton maturity can prevent Q angle-related misalignments and abnormalities in the limb.

Icy Intrigue: A Case Report of an Unusual Encounter With an Ice Pick Injury.

An ice pick is rarely observed as a weapon of offense in homicide or suicide. The severity of injuries produced by an ice pick ranges from circular contused abrasions to punctured wounds with clean-cut margins. We present a case of a self-inflicted ice pick injury to the chest autopsied at the AIIMS Rishikesh morgue. During this study, we noticed and analyzed the unusual presentation of injury by an ice pick, contrary to the injuries generally observed in ice pick cases. We highlight a peculiar case of a homicidal ice pick injury observed during the autopsy. The presentation deviated from typical patterns, with the weapon penetrating the victim's body in an unconventional manner. The findings challenge traditional assumptions regarding ice pick injuries and underscore the importance of comprehensive forensic analysis. Understanding and documenting atypical presentations of such injuries can aid forensic experts in accurately determining the cause and manner of death, facilitating the pursuit of justice in criminal investigations.

Mushroom Poisoning: A Case Series With a Literature Review of Cases in the Indian Subcontinent.

Mushroom is a fungus widely used as an edible in various parts of the world, especially in hilly regions with damp climates. Nevertheless, when picked from the wild to use as a vegetable, it has proved fatal for people ingesting it due to a lack of knowledge for distinguishing between poisonous and non-poisonous mushrooms by the people of the local community. Three cases presented as emergencies from a single household comprising a 13-year-old girl and both her grandparents following the ingestion of mushrooms picked from a nearby forest area. Luckily the parents of the girl were out for work, so they survived and helped identify the mushroom. Most cases are not reported or documented, and data are present mainly in the form of case reports.

Determinants of utilization of antenatal care services among recently delivered women residing in urban poor areas of Rishikesh, Uttarakhand, India-a cross-sectional study.

Objective: To determine the proportion of women having four or more antenatal care (ANC) visits and to assess associated factors (utilization of ANC services) in poor urban settlements in Rishikesh, Uttarakhand. Material and Methods: This was a community-based cross-sectional study. The study population included females who delivered during the last year residing in the target location. The data were collected through the house-to-house method in the four selected areas using a structured pre-tested expert-validated questionnaire. Data analysis was performed using SPSS version 23 using descriptive and multivariate statistical techniques. Results: There was a 59.66% prevalence of four or more antenatal visits (52.01%-66.97%). Only 26.44% of the participants confirmed their husbands' company during their antenatal visits. Socioeconomic status, type of family, mother's educational status, parity, husband's company during the visit, and mother's autonomy were significant factors (P<0.005) associated with the number of ANC visits. In logistic regression, after adjusting for other covariates, the autonomy of the participants and the husband's involvement during the visit were found to be significantly associated with four or more ANC visits. Conclusions: Approximately 60% of participants in poor urban settlements had four or more ANC visits. The findings of our study affirm the involvement of husbands in antenatal visits and women's autonomy as significant determinants of antenatal care utilization.

A Systematic Review on Quadriceps Angle in Relation to Knee Abnormalities.

Previous studies on the quadriceps (Q) angle and its relation to knee problems have led to conflicting conclusions. In this comprehensive review, we evaluate recent studies on the Q angle and analyze the changes in Q angles. Specifically, we investigate the variation in Q angles when measured under the following conditions: 1) under various measurement techniques; 2) between symptomatic and non-symptomatic groups; 3) between samples of men and women; 4) unilateral versus bilateral Q angles; 5) Q angle in adolescent boys and girls. It is widely believed that Q angles are more significant in symptomatic patients than in asymptomatic individuals or that the right lower leg and left lower limb are equivalent, which is supported by little scientific data. However, research states that young adult females have higher mean Q angles than males.

Myocardial Infarction With Ventricular Wall Aneurysm: A Case Report.

A ventricular aneurysm can be pseudo or true; it is a rare complication of myocardial infarction induced by an intra-myocardial dissecting hematoma due to fragile myocardium. Ventricular wall rupture takes place two to four days after myocardial infarction when coagulative necrosis and inflammatory infiltrate and lysis of myocardial connective tissue results in weakening of infarcted myocardium. Acute cardiac wall ruptures are mostly fatal; an unwittingly located pericardial adhesion can abort a rupture resulting in a false aneurysm. The wall of a false aneurysm consists of the epicardium in contrast to a true aneurysm, which is composed of the myocardium. True aneurysms are complications seen in transmural infarcts. Thinned-out scar tissue paradoxically bulged during systole, and toughened fibrotic wall rupture doesn't usually occur. Deaths in subjects with true ventricular aneurysms occur due to mural thrombus, arrhythmias, and heart failure. We encountered a case of a true aneurysm, as reported below.

A Preliminary Study of Organ Weight After Histological Exclusion of Abnormality During Autopsy in the Adult Population of Uttarakhand, India.

Organomegaly can be a strong predictor of an underlying pathological condition. There are many standard tables available in various texts listing the normal organ weight range, yet there is a lack of a standard table that is accepted globally. The main reason behind this is variation in organ weight due to socioeconomic status, geographical variation, and racial and stature variation among different global populations. The Western population has different stature compared to our population, that is, residents of Uttarakhand, India. Different studies tabulated organ weights in different regions of the world and correlated with different bodily parameters such as sex, race, stature, BMI, etc, which have shown a significant variation. There are different sets of data available that cannot be accepted universally due to regional variation. Most of the studies done in various parts of the world do not specify the condition of the organ, whether it was normal at the time of study or not. The methods of dissection of organs were also not explained in different studies. In this study, a total of eight organs were weighed from 137 autopsies conducted at the mortuary of the All India Institute of Medical Sciences Rishikesh over a period of 1.5 years. It was found that the average brain weighed in males was 1313.2 gm (±127.7 gm) and among females, it was 1218.0 gm (±122.82 gm). The weight of the heart was 310.1 gm (±83.97 gm) in males and 241.2 gm (±71.42 gm) in females. Right and left lungs weighed 499.4 gm (±207.5 gm)/407.5 gm (±128.66 gm) and 459.6 gm (±179.19 gm)/369.4 gm (±144.17 gm) among males and females, respectively. The liver weight was 1477.0 gm (±370.52 gm) in males and 1309.0 gm (±274.18 gm) among females. Spleen weighed 154.0 gm (±74.63 gm) in males and 156.0 gm (±65.0 gm) in females. The right and left kidneys weighed 125.9 gm (±37.92 gm)/108.1 gm (±28.80 gm) and 126.3 gm (±31.26 gm)/106.6 gm (±22.4 gm) among males and females, respectively. In our study, we have done a histological examination to rule out any pathological condition before including the weight of the organs in the study. The present study is to derive a standard organ weight among the inhabitants of Uttarakhand, India, and to look for a variation in organ weight among different studies done in the past in different regions of the world.

Methanol Poisoning: An Autopsy-Based Study at the Tertiary Care Center of Uttarakhand, India.

Aims and objective This study describes postmortem and histopathological findings to understand the internal progression of methanol poisoning. The study also aims to examine clinical, biochemical, and histological changes seen with methanol poisoning. Materials and methods The study describes the methanol poisoning tragedy that occurred in February 2019 in the Haridwar district of Uttarakhand. Ninety-one patients were admitted to the hospital, four were brought dead, four died within a few hours of admission (designated as early deaths), and four died between 10 and 45 days of hospitalization (designated as late deaths). A medicolegal autopsy was performed on all 12 deaths. Gross external and internal findings were noted, and routine viscera and blood were preserved and sent to Uttarakhand's Forensic Science Laboratory (FSL) to estimate methyl alcohol. A section of the optic nerve was taken from the optic chiasma for histopathological examination. Data were collected retrospectively from records. All data were tabulated and analyzed using Microsoft Excel version 2019. The study was approved by the Institutional Ethics Committee of All India Institute of Medical Sciences (AIIMS), Rishikesh (249201), Uttarakhand, India. Results Methanol poisoning is a health-associated disaster in many regions of India. Autopsy, including histopathological examination, could elicit the adverse effects of methanol on different organs. Their mean age was 37.7 years (range 21-70), and 67% (n = 8) of all victims were in the age range of 30-50 years. The average methyl alcohol level reported among hospital deaths and brought dead was 116.08 mg/dl and 224.6 mg/dl, respectively. A blurred vision had been their most common complaint, identified in 75% (n = 6), followed by vomiting and abdominal pain, while 50% (n = 4) had features of respiratory insufficiency. Mean pH and bicarbonate levels among hospital deaths were 6.61 mmol/l and 6.18 mmol/l, respectively. An autopsy revealed signs of hypoxia in all cases. Internal organs were congested. Severe metabolic acidosis leading to the respiratory failure was the cause of death in early deaths. Cerebral and pulmonary edema consequent upon septicemic shock was the cause of late deaths. A case with the most extended survival duration showed cerebral edema with intracerebral hemorrhage. Cirrhotic liver, along with features of renal failure, was an additional internal finding in late deaths. Optic nerve histopathology showed no demyelination or axonal necrosis; however, mild edematous changes were evident. Conclusions Methanol poisoning is one of the manmade disasters in the developing world. There are various adverse effects of different organs and organ systems inside the body. Timely intervention and diagnosis can save several lives. The organ-directed meticulous autopsy can help autopsy surgeons in establishing the diagnosis and thus help the judiciary in delivering justice to the sufferers.

An Unusual Encounter of Skin Condition Mimicking Acrokeratosis Paraneoplastica (Bazex Syndrome).

Acrokeratosis paraneoplastica is a rare paraneoplastic skin disease in which there are erythematous violaceous, scaly plaques on the hands, feet, and acral locations. There is a relationship between various carcinomas of the aerodigestive tract and skin eruptions. These were the pioneering work done pertaining to a clinical entity that was showing some inter-relationship between a skin condition and carcinoma anywhere inside the body. Bazex syndrome is mostly associated with carcinomas of the upper aero-digestive tract, but other malignancies were also being reported. In this case, the patient was in advancing age with cachexic features along with liver and lung lesions which prompted us to investigate histologically for evidence of malignancy which came out to be negative. In our case, lungs showed features of pulmonary edema with normal histology. When we examined the liver, gross lesions were present but no evidence of malignancy was noted and the liver showed normal parenchyma histologically. Specimens taken from hand and foot showed hyperkeratosis along with bacterial colonies in the overlying epidermis. The spleen showed red pulp with congestion and hemorrhage. Similarly, sections from the kidneys were showing interstitial inflammation and congestion of blood vessels. Specimens from the brain and heart showed unremarkable histology.
