Abstract:
Commotio cordis is a rare and catastrophic mechano-electric feedback syndrome, and it is especially apt to occur in male children, adolescents and youths during sports activities. The authors present a case of unexpected sudden death due to commotio cordis associated with violence. In a house of detention, a 19-year-old boy was punched and kicked in the face, neck and chest during a fight with another suspect in their ward. Unfortunately, his precordium was the major injured region. The victim turned pale, then lost the ability to resist and lost consciousness immediately. When the emergency medical personnel arrived, the victim was found in a condition of cardiac and respiratory arrest and he was pronounced dead at the scene without cardiopulmonary resuscitation. Both autopsy signs and forensic morphology were in accord with the criteria for commotio cordis diagnosis, showing no cardiac or other organic fatal lesions and no underlying cardiac diseases; moreover, the toxicological screening was negative for alcohol, drug and common toxicants. In the present case, the whole fight was seen by some witnesses in their ward, and it was recorded by the monitoring unit. Based on the statements of the witnesses and the monitoring videotape, combined with the forensic pathological and toxicological examinations, all the testimonies supported the conclusion that the cause of death was commotio cordis.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.
Impact
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...
