Dancing to death: A case of heat stroke

Nadesan K, Kumari C, Afiq M

J Forensic Leg Med, 2017 Aug;50:1-5.
PMID: 28651196 DOI: 10.1016/j.jflm.2017.05.008

Heat stroke is a medical emergency which may lead to mortality unless diagnosed early and treated effectively. Heat stroke may manifest rapidly, hence making it difficult to differentiate it from other clinical causes in a collapsed victim.(1) We are presenting a case report of twelve patients who were admitted to our emergency department from a music festival held on 13-15th of March 2014. They developed complications arising from a combination of severe adverse weather condition, prolonged outdoor physical exertion due to long hours of dancing and drug-use, resulting in heat stroke. Three of them died while the remaining patients survived. Their condition was initially misdiagnosed as a classical illicit drug overdose. This was based on the history of drug ingestion by some of the patients who attended the music festival on that day. The information in this case report aims, to create awareness amongst members of the medical team on duty in outdoor events, pre hospital responders and ED physicians when treating and managing similar cases in the future. In addition it is intended to warn the organizers of such events to take adequate precautions to avoid such tragedies in the future.

Nor FM, Abdullah N, Mustapa AM, Qi Wen L, Faisal NA, Ahmad Nazari DA

J Forensic Leg Med, 2013 Nov;20(8):947-52.
PMID: 24237796 DOI: 10.1016/j.jflm.2013.09.006

Estimation of stature is an important step in developing a biological profile for human identification. It may provide a valuable indicator for an unknown individual in a population. The aim of this study was to analyse the relationship between stature and lower limb dimensions in the Malaysian population. The sample comprised 100 corpses, which included 69 males and 31 females between the age range of 20-90 years old. The parameters measured were stature, thigh length, lower leg length, leg length, foot length, foot height and foot breadth. Results showed that the mean values in males were significantly higher than those in females (p
The applicability of Greulich and Pyle atlas to assess skeletal age for four ethnic groups

Mansourvar M, Ismail MA, Raj RG, Kareem SA, Aik S, Gunalan R, et al.

J Forensic Leg Med, 2014 Feb;22:26-9.
PMID: 24485416 DOI: 10.1016/j.jflm.2013.11.011

Recently, determination of skeletal age, defined as the assessment of bone age, has rapidly become an important task between forensic experts and radiologists. The Greulich-Pyle (GP) atlas is one of the most frequently used methods for the assessment of skeletal age around the world. After presentation of the GP approach for the estimation of the bone age, much research has been conducted to examine the usability of this method in various geographic or ethnic categories. This study investigates on a small-scale and compares the reliability of the GP atlas for assessment of the bone age for four ethnic groups - Asian, African/American, Caucasian and Hispanic - for a different range of ages.
Review of forensically important entomological specimens collected from human cadavers in Malaysia (2005-2010)

Kavitha R, Nazni WA, Tan TC, Lee HL, Azirun MS

J Forensic Leg Med, 2013 Jul;20(5):480-2.
PMID: 23756518 DOI: 10.1016/j.jflm.2013.03.007

Forensic entomological specimens collected from human decedents during crime scene investigations in Malaysia in the past 6 years (2005-2010) are reviewed. A total of 80 cases were recorded and 93 specimens were collected. From these specimens, 10 species of cyclorrphagic flies were identified, consisting of Chrysomya rufifacies (Macquart) -38 specimens (40.86%), Chrysomya megacephala (Fabricius) -36 specimens (38.70%), Chrysomya villeneuvi (Patton) -2 specimens (2.15%), Chrysomya nigripes (Aubertin) -2 specimens (2.15%), Chrysomya pinguis (Walker) -1 specimen (1.08%), Hermetia illucens (Linnaeus) -1 specimen (1.08%), Hemipyrellia liguriens (Wiedemann) -5 specimens (5.37%), Synthesiomyia nudiseta (Wulp) -1 specimen (1.08%), Megaselia scalaris (Loew)-1 specimen (1.08%) and Sarcophaga ruficornis (Fabricius) -4 specimens (4.30%). In two specimens (2.15%), the maggots were not identifiable. Ch. megacephala and Ch. rufifacies were the commonest species found in human decedents from three different ecological habitats. S. nudiseta is an uncommon species found only on human cadavers from indoors. A total of 75 cases (93.75%) had a single fly infestation and 5 cases (6.25%) had double fly infestation. In conclusion, although large numbers of fly species were found on human decedents, the predominant species are still those of Chrysomya.
The effect of post-mortem computed tomography angiography (PMCTA) on biomarkers of coronary artery disease

Woon CK, Omar E, Siew SF, Nawawi HM, Kasim NAM, Chainchel Singh MK

J Forensic Leg Med, 2024 Feb 01;102:102654.
PMID: 38310784 DOI: 10.1016/j.jflm.2024.102654

Coronary atherosclerosis is due to build-up of plaque within the coronary arteries. Post-mortem computed tomography (PMCT) allows non or minimally invasive visualization of abnormalities prior to an autopsy, however PMCT-angiography (PMCTA) greatly enhances relevant findings, especially in viewing the cardiovascular system which is important in the diagnosis of coronary atherosclerosis. Contrast media used in PMCTA however has been reported to cause distortion of tissue which may interfere with post-mortem investigation outcomes. A cross sectional study to investigate the effect of PMCTA on tissue biomarkers in coronary arteries was performed involving cases brought in dead to the Institute and Accident and Emergency Unit. Sixty-three autopsy cases were included in this study, whereby 18 cases underwent PMCT while 45 cases underwent PMCTA. The subjects subsequently had a conventional autopsy where coronary artery sections were collected for standard histological examination and immunohistochemistry examination for endothelial inflammatory (CD36), prothrombogenic (TPA) and plaque stability (MMP-9) markers. The subjects consisted of 55 males and 8 females with a mean age ±SD of 49 ± 18.11 years. There were no significant differences in the coronary artery endothelial expression of CD36, MMP-9 and TPA between PMCT and PMCTA subjects. PMCTA does not alter CD36, TPA and MMP-9 markers supporting the safe use of PMCTA in post-mortem examinations.
Gunshot wound in skeletonised human remains with partial adipocere formation

Mohd Nor F, Das S

J Forensic Leg Med, 2012 Jan;19(1):42-5.
PMID: 22152448 DOI: 10.1016/j.jflm.2011.07.008

We present a case of skeletonised human remains. In the present case report, a body was exhumed from the ground above a cemetery. On exhumation, the body was partially-skeletonised with adipocere formation on the upper part of the body. Autopsy of the body showed two bullets in the right thigh muscle and lumbar vertebrae between L4 and L5. Postmortem changes and destruction of soft tissue made it impossible to determine direction of fire through the body, even in a careful complete autopsy.
Planned complex suicide: self-strangulation and fall from height

Nor FM, Das S

J Forensic Leg Med, 2011 Oct;18(7):336-9.
PMID: 21907941 DOI: 10.1016/j.jflm.2011.06.013

We hereby present a case of planned complex suicide. In this case study, we report a teen-aged girl who committed suicide by strangulating herself, and subsequently fell from the 13th floor of a housing apartment. The planned complex suicide was substantiated by the presence of a suicide note and a photograph captured in a mobile handset. To the best of our knowledge, it is the first case involving self-strangulation and fall from height, in which the photograph was stored in the handset. This is to further emphasize that objects like mobile handsets can be important in determining the cause and manner of death. The available evidence at the site of incident should be explored meticulously in order to arrive at a proper conclusion.
Silent bony calcification of coronaries in an adolescent--an unusual case

Murty OP, Mun KS, Hussin H

J Forensic Leg Med, 2008 Jan;15(1):37-41.
PMID: 18309549

This is a case report of 16-year-old adolescent school boy who died due to unusual calcification of coronary arteries. He died while cycling with his friends. While cycling fast he fell. He was brought dead to hospital. At times unsuspected cardiac lesions cause sudden death during extraneous physical activities in healthy persons. Sudden death in adolescents is not very common. It is an unusual case as apparently healthy adolescent boy actively participating in sports had stony hard coronary arteries. The coronaries showed advanced calcification and early bone formation. The myocardial septum had extensive fibrosis. The pathogenesis and other possible similar conditions are also discussed in the report.
Inheritance pattern of lip prints among Malay population: A pilot study

George R, Nora Afandi NS, Zainal Abidin SN, Binti Ishak NI, Soe HH, Ismail AR

J Forensic Leg Med, 2016 Apr;39:156-60.
PMID: 26896666 DOI: 10.1016/j.jflm.2016.01.021

We assessed the resemblance of lip print patterns between parents and biological offspring in families of 31 Malay students as well as the distribution of different types of lip print in the study group. Only a few studies have successfully established the inheritance pattern of lip prints. Such studies can be population specific and need to be conducted in various populations. No such study have been conducted in Malay population in Malaysia, according to our knowledge. Present study was carried out to ascertain whether there is any inherence pattern in lip prints and thereby to investigate the potential role of lip prints in personal identification. We found 58.06% resemblance of lip print patterns between the parents and their biological offspring in our study. The influence of heredity in lip print pattern is still a new concept and there is lack of concrete evidence. The data from our study shows that there is potential influence of inheritance in the lip print patterns among the family members. Further researches involving larger samples size are suggested to derive more reliable and accurate results. The most common lip print pattern among the study group is type I (29.84%) followed by type II (23.12%), type III (22.45%), type I' (13.44%), type IV (9.54%) and type V (1.61%). Racial variations in lip print patterns and their prevalence may serve as an aid in forensic identification and crime scene investigation. The results of this pilot study will help in establishing guidelines for future researches on lip print analysis in Malaysia.

Kumar V, Mohanty MK, Kanth S

J Forensic Leg Med, 2007 Jan;14(1):3-6.
PMID: 17046310

The purpose of this study was to record and evaluate the causes and the magnitude of the fatal burn injuries retrospectively. An analysis of autopsy records revealed 19.4% cases of burn injuries amongst the total autopsies done over 10years period (1993-2002) in the mortuary of the department of Forensic Medicine of Kasturba medical College, Manipal. The majority of deaths (78.5%) occurred between 11 and 40years of age group with preponderance of females (74.8%). The flame burns were seen in 94.1% of the victims followed by scalds and electrical burns in 2.8% and 2.5% cases, respectively. The majority of burn incidents were accidental (75.8%) in nature followed by suicidal (11.5%) and homicidal (3.1%) deaths. The percentage of burn (TBSA) over 40% were observed in most of the cases (92.5%). The majority of deaths occurred within a week (69.87%) and most the victims died because of septicemia (50.9%).

Forensic odontology plays a vital role in the identification and age estimation of unknown deceased individuals. The purpose of this study is to estimate the chronological age from Cone-Beam Computed Tomography (CBCT) images by measuring the buccal alveolar bone level (ABL) to the cemento-enamel junction and to investigate the possibility of employing the age-related structural changes of teeth as studied by Gustafson. In addition, this study will determine the forensic reliability of employing CBCT images as a technique for dental age estimation. A total of 284 CBCT images of Malays and Chinese patients (150 females and 134 males), aged from 20 years and above were selected, measured and stages of age-related changes were recorded using the i-CAT Vision software. Lower first premolars of both left and right side of the jaw were chosen and the characteristics described by Gustafson, namely attrition, secondary dentine formation and periodontal recession were evaluated. Linear regression analysis was performed for the buccal bone level and the R values obtained were 0.85 and 0.82 for left and right side respectively. Gustafson's characteristics were analysed using multiple regression analysis with chronological age as the dependent variable. The results of the analysis showed R values ranged from 0.44 to 0.62. Therefore it can be safely concluded that the buccal bone level highly correlated with the chronological age and is consequently the most suitable age-related characteristic for forensic age estimation.

PMID: 16530454

Death by hanging is believed to be a painless method of committing suicide. In most cases the noose has a knot and on this basis only it can be labeled as atypical or typical hanging. A 35 year Chinese man committed suicide by hanging with a ligature material made of electric wire where there was no knot present on the noose.
Estimation of stature from hand and handprint measurements in Iban population in Sarawak, Malaysia and its applications in forensic investigation

Zulkifly NR, Wahab RA, Layang E, Ismail D, Desa WNSM, Hisham S, et al.

J Forensic Leg Med, 2018 Jan;53:35-45.
PMID: 29149652 DOI: 10.1016/j.jflm.2017.10.011

Handprints and dismembered hands are commonly found during crime scene investigations and disaster victim identifications, respectively. It has been indicated that the accuracy of handprint and hand measurements for estimating stature maybe population specific. Since Iban is the largest ethnic population in Sarawak, Malaysia and because the application of anthropometry of hand and handprint within this population as well as other populations within the Southeast Asian countries remain unreported, this present study that investigated the reliability and accuracy of these two anthropometric aspects acquires forensic significance. Upon measuring the height, 21 measurements were recorded on each hand and the corresponding handprint of 50 male and 52 female consented adult Iban subjects. Using univariate statistics as well as simple and multiple regression analyses, interpretation of the measurements examined here was attempted. Results revealed that lengths of hand and handprint are the more reliable traits for estimating stature in both the male and female Iban subjects (p
Bandaged penis

Murty OP, Mahinda HA

J Forensic Leg Med, 2007 Jul;14(5):301-3.
PMID: 16962816

This is a case of a male in his late 30s who died due to acute myocardial ischemia. His penis was bandaged. The penis was inflamed and had infected abrasions. The possible relevances of such an incidental finding and its contribution to sudden death is explored. The case report shows photographs of the bandage in situ and its components, inflammation of frenulum, injury to the shaft, and the generalized inflamed and mildly swollen penis. These changes were considered to be caused by bites. The micro-photographic findings in the case were of acute myocardial ischemia, pulmonary oedema, and fatty liver.
The first case of C4-Blast related death in Malaysia: A multidisciplinary approach illustrated with emphasis on conjoint anthropologic and radiologic expertise in forensic identification of skeletal remains

Wong YL, Khoo LS, Ibrahim MA, Mohamad Noor MH, Mahmood MS

J Forensic Leg Med, 2021 Oct;83:102253.
PMID: 34543893 DOI: 10.1016/j.jflm.2021.102253

BACKGROUND: Blast related deaths are often shrouded by diagnostic and medicolegal complexities requiring multidisciplinary expertise in order to gauge accurate identification of the victims and document scientific investigations comprehensively. In the advent of more sophisticated technology, anthropologic methods can now be applied into post mortem imaging interpretation. The traditional imaging roles of characterizing osseous fragmentation, detecting and localizing foreign bodies can be expanded to simulate and support physical anthropologic examination to assist in documentation for court proceedings.
CASE PRESENTATION: An assemblage of unidentified, incomplete, highly fragmented skeletal remains were found scattered on a bare area of land in a forest. There was evidence of an explosion given the pattern of scattered evidentiary material of explosive and ballistic nature. Laboratory analysis of white powder found within the explosive material confirmed the presence of high impact C4-explosive trace containing cyclotrimethylene trinitramin [Royal Demolition Explosive (RDX)] & pentaerythritol tetranitrate (PETN). It took meticulous multidisciplinary efforts to confirm the identity of the victim that was marred by the severe fragmentation and skeletalization of the remains. The initial radiologic interpretation focused more on identification of foreign bodies and supporting documentation of fragmentation. With the current availability of post computed tomography (PMCT) in our center, we reexamined the value and potential of PMXR and PMCT as an adjunctive tool for biological profiling.
CONCLUSION: This was the first case of C4-blast related death reported in Malaysia. The multidisciplinary approach in efforts to identify the victim may serve as a guide in managing, coordinating and maximizing the expertise of different forensic specialists, with emphasis on anthropologic and radiologic collaboration.
Paraquat poisoning calls to the Malaysia National Poison Centre following its ban and subsequent restriction of the herbicide from 2004 to 2015

Leong YH, Ariff AM, Khan HRM, Rani NAA, Majid MIA

J Forensic Leg Med, 2018 May;56:16-20.
PMID: 29525581 DOI: 10.1016/j.jflm.2018.03.007

This study analyses the incidences and patterns of paraquat poisoning from calls received at the Malaysia National Poison Centre (NPC) since 2004 following the ban of the herbicide (2004-2006) and subsequent restriction up to year 2015. Related reported cases to the centre over twelve years (2004-2015) were retrieved and studied in respect to socio-demographic characteristics, mode and type of poisonings, exposure routes and location of incident. Ages of poisoned victims range from 10 months old to 98 years with males being intoxicated more frequently than females (ratio male to female = 2.7). The age group mainly involved in the poisoning was 20-39 years. The most common mode was intentional (62.8%) followed by unintentional (36.9%). Among the 1232 reported cases, suicidal poisoning was the highest (57.2%); accidental poisoning (30.8%) and occupational poisoning (3.3%). The findings showed an upward trend of suicidal poisoning over the years, clearly emphasizing the need for more stringent and effective enforcement to ensure the safe use of paraquat.

The third molar development (TMD) has been widely utilized as one of the radiographic method for dental age estimation. By using the same radiograph of the same individual, third molar eruption (TME) information can be incorporated to the TMD regression model. This study aims to evaluate the performance of dental age estimation in individual method models and the combined model (TMD and TME) based on the classic regressions of multiple linear and principal component analysis. A sample of 705 digital panoramic radiographs of Malay sub-adults aged between 14.1 and 23.8 years was collected. The techniques described by Gleiser and Hunt (modified by Kohler) and Olze were employed to stage the TMD and TME, respectively. The data was divided to develop three respective models based on the two regressions of multiple linear and principal component analysis. The trained models were then validated on the test sample and the accuracy of age prediction was compared between each model. The coefficient of determination (R²) and root mean square error (RMSE) were calculated. In both genders, adjusted R² yielded an increment in the linear regressions of combined model as compared to the individual models. The overall decrease in RMSE was detected in combined model as compared to TMD (0.03-0.06) and TME (0.2-0.8). In principal component regression, low value of adjusted R(2) and high RMSE except in male were exhibited in combined model. Dental age estimation is better predicted using combined model in multiple linear regression models.

J Forensic Leg Med, 2009 Jul;16(5):290-6.
PMID: 19481715 DOI: 10.1016/j.jflm.2008.12.020

Domestic maid violence is an assault and coercive behaviour, which mainly includes physical, psychological and at times sexual too, by employer or household members of employer against a person hired as a domestic help. Maid abuse is well known but poorly documented in scientific literature. This is an important global issue. In this article, two illustrated cases of maid abuse are discussed. Their employers allegedly subjected both the victims to physical and psychological trauma. The physical examination of the victims showed poor state of clothing, nutrition, and presence of injuries of different duration. The bruises were irregular to patterned, and were inflicted by beating. Both cases had eczematous contact dermatitis over palms and soles, paronechia, and sub-ungal fungal infection due to unprotected working in wet conditions. In both cases, external ears were deformed like cauliflowers due to repeated trauma. All cases had multiple injuries of varying duration. In this paper, medico-legal and social issues related to maid abuse are also discussed in detail. A possible solution to minimise maid abuse is also suggested. This paper highlights and document maid abuse.
