Cerebral hypoxic seizures (or convulsions).I've heard or read somewhere that just prior to death from that type of head injury, the victim would have something along the lines of a seizure (may not be the correct term) because the brain is starving for oxygen.

I don't believe the blood tinged saliva has anything to do with oral sex. It is however very common in strangulation. From the book Forensic Medicine: Clinical and Patholigical Aspects, Page 267 (bbm):Thank you for finally making this statement. I have long wondered about an oral situation because of the reference to the possibility of blood tinged saliva on JB's cheek. According to the autopsy, there was no sign of blood in the ear or nasal canals, or in the stomach or esophagus. Or abrasions noted around the lips or mouth.
The "biting injuries" the author is speaking to above are injuries to the victim's own tongue or lips. Jonbenet had none of these type of injuries, and therefore, I don't believe she had convulsions as a result of the loss of oxygen to her brain. Convulsions (or seizures) are not always a result, especially if there are other injuries, and especially an injury causing unconsciousness.Traces of saliva may be present at the corners of the mouth. Salivation is increased by stimulation of the pterygopalatine ganglion. This excessive saliva runs from the angles of the mouth downwards, if the mouth is not positioned horizontally, and mostly drops onto the clothes in the area of the chest. The traces of the dried saliva then make it possible to judge whether the situation in which the body was found corresponds to that at the time that the person was hanging. Increased amounts of secretions may be discharged from the nose as well. Both secretions may be tinged with blood.
Bleeding (note: the author is referring here to actual bleeding) from the mouth can also be the result of injuries to the mucous membranes of the tongue or lips due to convulsion, with corresponding biting injuries, the convulsions resulting from cerebral hypoxia.
