Sudden cardiac death in a young athlete due to anomalous origin of both coronaries from a common ostium

Sudden cardiac death (SCD) in young people is a tragic event and a worldwide public health issue. SCD is the most common cause of death in young athletes and is related to acquired/congenital cardiac disorders, such as cardiomyopathies, congenital coronary anomalies and ion channelopathies. We report the case of a 14-year-old male non professional athlete who was apparently...

Insect succession patterns on pig carrion in southern Nigeria

In analyzing decomposing human remains in cases of unattended death, observing insect succession patterns to aid in estimating the post-mortem interval (PMI) based on carrion insects is one of the tasks of the forensic entomologist. The purpose of this study is to provide baseline data in order to improve PMI estimates using carrion insects. The lingering armed conflict in...

New molecular markers to differentiate carbon dioxide intoxication from asphyxia due to oxygen deficiency

The lack of specific autopsy findings for carbon dioxide (CO2) intoxication hinders the determination of cause of death based on autopsy findings alone. In addition, when death occurs in a space is filled with CO2 or other gases, the cause of death must be distinguished between intoxication and asphyxia due to oxygen deficiency, which also has no specific autopsy findings. In...

External causes of death in younger than 18 years old in Portugal in the last 10 years - a retrospective analysis

Pediatric mortality from external causes has been a worldwide concern in the last decades. In particular, the prevalence of accidental deaths is a key concern, especially traffic accidents.
