Medico-legal autopsies of homicidal deaths: A five-year retrospective study in Hospital Sungai Bul

@#Introduction: Homicide is the act of killing one human being by another, encompassing death as a result of criminal act including justifiable homicide such as judicial killing and self-defence. This study aimed to ascertain the epidemiology and patterns of injury of homicide victims. Materials and Methods: We reviewed records of medico-legal autopsy cases performed at the Department of Forensic Medicine, Hospital Sungai Buloh, for a period of five years, from January 2012 until December 2016. Subjects’ demographic data such as age, gender, nationality, ethnicity and cause of death were recorded. Results: A total of 122 homicide cases were documented. 90% of the victims were 18 to 65 years old. Males contributed 80% of the subjects. An alarming 42% of the subjects comprised of non-Malaysians. Indonesian subjects contributed one-third of the non-citizen category, followed by Bangladeshis at 20.4%. Other nationalities were Burmese, Nepalese, Pakistani, Vietnamese and unspecified. Among Malaysians, 50% of the subjects were Indians, followed by Malay (31.5%) and Chinese (17.8%). Sharp and blunt force traumas were the most common injuries found, contributing 33% and 32% respectively. Asphyxiation and firearm injuries recorded an almost similar frequency, contributing 25% in combination. Other patterns included combined sharp and blunt objects (4.9%) and burns (3%). Conclusions: A large number of immigrants in the country have significantly increased the forensic casework. Sharp and blunt objects continue to be the weapon of choice due to its easy accessibility. As domestic violence including fatal spousal and child abuse continue to rise, in-depth study in the area is warranted. Keywords: h

Association of coronary artery calcium score with calcification and degree of stenosis: An autopsy study

@#Introduction: Coronary artery disease (CAD) is a known cause of major cardiovascular events and calcium score (CS) has been developed as a marker of coronary atherosclerosis. Yet, the relationship between post mortem computed tomography (PMCT) CS with histologically observed calcification and the severity of coronary artery stenosis has not been widely explored and is still unclear. This study aims to determine the association between coronary artery PMCT CS with histologically observed calcification and degree of stenosis of coronary arteries in post-mortem cases. Materials & Methods: This was a cross-sectional study involving 101 subjects recruited from the National Institute of Forensic Medicine (IPFN) Hospital Kuala Lumpur (HKL) over a period of 15 months, from December 2012 until April 2014. PMCT CS of the coronary arteries was calculated using Agatston-Janowitz score. Histological presence of calcification was observed and the degree of stenosis was calculated using an image analysis technique. Results: PMCT CS increased with increasing severity of stenosis (p<0.001). PMCT CS showed a positive correlation with the presence of calcification (r=-0.82, p<0.001). Conclusion: Calcium score is strongly associated with coronary artery calcification and the degree of luminal stenosis in post mortem subjects. Thus, PMCT may be useful as a non-invasive tool in diagnosing CAD in the event that an autopsy is not possible.

Pathological autopsy: Most valuable aid in the present medical and medico-legal scenario.

It is a fact that the advancements in medicine would not have been possible without the help of autopsies, may be pathological or clinical or medico-legal. Mankind has been immensely benefited by the autopsies all these years. With the changing disease patterns, re emerging diseases, environment and social system, autopsies have become more necessary and relevant than before. The objectives of an autopsy examination are not being achieved at the highest level due to under trained medical officers who handle more than 80% of autopsy work in India and also due to the unwillingness or inertia of pathologists or clinicians to perform the autopsies. Here the in this article we try to highlight the contributions of pathological autopsies to the medical sciences & our social system. We also discuss why there is urgent need for more and well organized clinical or pathological autopsies through out the nation.

Síndrome de la niña y el niño sacudidos: hallazgos anatomoclínicos / Shaken baby syndrome: anatomoclinic features

El síndrome del niño sacudido es una de las formas más severas de maltrato infantil que ocurre principalmente en niños menores de un año. Por la vulnerabilidad de las víctimas y por las secuelas que puede producir, incluyendo la muerte, es necesario, en el abordaje clínico, tener presente la sospecha diagnóstica ante lesiones de explicación insatisfactoria por parte de los encargados del menor. Asimismo si se trata de un abordaje médico legal deben tenerse las consideraciones necesarias para documentar las lesiones, tanto en el paciente vivo, como en los casos de homicidio, para colaborar con la administración de justicia. Para ello se debe tratar de implementar una metodología homogénea para la realización de dichas pericias, tanto en la parte clínica como patológico forense. En este artículo se describe la forma habitual de presentación clínica del síndrome del niño sacudido y se expone una guía básica para la realización de autopsias medico legales en casos de muertes por esta causa.

The shaken baby syndrome is one of the most severe presentations of child abuse that is seen in children especially under the first year of age. The great vulnerability of this group of patients and the serious consequences that they may encounter in the future, including death, are enough reason to inquire, during the clinical approach, about the possibility that the patient being attended may be a victim of physical abuse. From a medico-legal evaluation, it is pertinent to document and describe thoroughly the physical lesions in the living patient and in cases of homicide, in order to contribute scientifically in the administration of justice. For that reason it is essential to follow a uniform methodology in the management of both the clinical and the forensic assessment. This article reviews the usual clinical presentation of the shaken baby syndrome and proposes a basic guide to evaluate the autopsies in cases of deaths originated by this cause.
