Feasibility study of immediate pharyngeal cooling initiation in cardiac arrest patients after arrival at the emergency room.

Aim: Cooling the pharynx and upper oesophagus would be more advantageous for rapid induction of therapeutic hypothermia since the carotid arteries run in their vicinity. The aim of this study was to determine the effects of pharyngeal cooling on brain temperature and the safety and feasibility for patients under resuscitation.

Methods: Witnessed non-traumatic cardiac arrest patients (n=108) were randomized to receive standard care with (n=53) or without pharyngeal cooling (n=55).

Chronic subdural hematoma associated with arachnoid cyst. Two case histories with pathological observations.

Arachnoid cysts are well known to induce chronic subdural hematoma (CSDH) after head injury. However, histological observations of the arachnoid cyst and hematoma membrane have only been rarely described. An 8-year-old boy and a 3-year-old boy presented with CSDH associated with arachnoid cyst.

[Vertebral arteriovenous fistula as a complication of atlantoaxial transarticular screw fixation--case report].

We report a rare case of a vertebral arteriovenous fistula that developed as a complication of atlantoaxial transarticular screw fixation. The patient was a 44-year-old male with a history of juvenile rheumatoid arthritis. He had undergone an atlantoaxial transarticular screw fixation for an atlantoaxial dislocation.
