The purposes of the study were to determine the total cost of Ankara Emergency Aid and Rescue Services (EARS), to calculate the cost of a single ambulance response and the cost per patient responded to. A descriptive study was planned to find out the cost of Ankara EARS, conducted between 1 October 1995 and 30 September 1996. The main variables of the study were the capital and recurrent costs of the system. ⋯ On the other hand the cost per patient or injured person was US$180.50. In Ankara, Turkey, the costs of such ambulance services could not be afforded by the private sector. The ambulance service activities should continue to be a part of primary health care services and the Ministry of Health should continue to serve in this field.

Brain oedema is a major factor contributing to the poor outcome of subjects with acute ischaemic stroke but the use of mannitol and other hyperosmolar agents in this setting is controversial and hardly debated. Recent data have demonstrated that mannitol at concentrations which may be achieved in clinical conditions and hyperosmotic stress itself can activate the process of apoptotic cell death. ⋯ Furthermore, apoptosis in ischaemic areas closely parallels the timing of brain oedema and this suggests that a cause-effect relationship links the two phenomena rather than simply a temporal correlation. On this basis, it is crucial that emergency-physicians critically rethink the management strategy of brain oedema associated with ischaemic stroke.

To evaluate the rate of diagnostic errors leading to preventable deaths among patients admitted to our intensive care unit (ICU), we retrospectively reviewed the medical and autopsy records of all patients who died in the ICU between 1 January 1991 and 31 December 1993. Excluded were patients with traumatic injuries, cerebrovascular accidents and primary cardiac arrest. According to their length of stay (LOS) in the ICU, patients were subdivided into Group A (LOS 0-24 hours), Group B (LOS > 24 hours-14 days), and Group C (LOS > 14 days). ⋯ Type 2 errors were 18% in Group A, 34% in Group B, and 30% in Group C. Fully correct diagnoses or Type 3 errors were present in 77% of patients in Group A, 62% of patients in Group B, and 61% of patients in Group C. Clinical errors of any type were not related with the LOS in the ICU or in the hospital, age and the number of underlying chronic diseases.
