In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside ...

Stab wounds to the heart are typically survivable with medical attention, though gunshot wounds to the heart are not. The right ventricle is most susceptible to injury due to its prominent location.

[2] [3] Causes of a primary CSF leak are those of trauma including from an accident or intentional injury, or arising from a medical intervention known as iatrogenic. A basilar skull fracture as a cause can give the sign of CSF leakage from the ear, nose or mouth. [4] A lumbar puncture can give the symptom of a post-dural-puncture headache.
Closed-head injuries are the leading cause of death in children under 4 years old and the most common cause of physical disability and cognitive impairment in young people. [ 1 ] [ 2 ] Overall, closed-head injuries and other forms of mild traumatic brain injury account for about 75% of the estimated 1.7 million brain injuries that occur ...
TBI is a leading cause of death and disability around the globe [8] and presents a major worldwide social, economic, and health problem. [10] It is the number one cause of coma, [169] it plays the leading role in disability due to trauma, [76] and is the leading cause of brain damage in children and young adults. [15]
The bacteria generally enter through a break in the skin, such as a cut or puncture wound caused by a contaminated object. [1] [3] They produce toxins that interfere with normal muscle contractions. [4] Diagnosis is based on the presenting signs and symptoms. The disease does not spread between people. [1]
