Abstract:
A prison inmate was referred to us for diagnostic procedures and therapy due to a combination of pneumomediastinum with emphysema of neck and face. External injuries were absent and pathogenesis remained uncertain until thorough examination of the patient revealed two intraoral wounds, presumably from a needle, reaching into the maxillary sinus. This large subcutaneous emphysema of the face, neck and mediastinum was the result of an exaggerated Valsalva maneuver. With this self-inflicted injury, unknown to us, the prisoner achieved the desired immediate admission to hospital.

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...
