The aim of present study was to examine whether systemically delivered glial cell-derived neurotrophic factor (GDNF) was beneficial in reversing the spinal cord injury (SCI) in a spinal cord compression model. Rats were divided into three major groups: (1) sham operation (laminectomy only); (2) laminectomy+SCI+normal saline (1 ml/kg, i.v.); (3) laminectomy+SCI+GDNF (50 ng/kg, i.v.). Spinal cord injury was induced by compressing the spinal cord for 1 min with an aneurysm clip calibrated to a closing pressure of 55 g. ⋯ It was found that systemically delivered GDNF, but not vehicle solution, significantly attenuated the SCI-induced hind limb dysfunction and spinal cord infarction and apoptosis. Both GDNF and VEGF could be detected in the injury spinal cord after GDNF, but not vehicle solution, therapy. The results indicate that GDNF treatment may be beneficial in reversing hind limb dysfunction by reducing spinal cord infarction and apoptosis in a spinal cord compression model.

Practice Guideline
Emergency treatment of anaphylactic reactions--guidelines for healthcare providers.
*The UK incidence of anaphylactic reactions is increasing. *Patients who have an anaphylactic reaction have life-threatening airway and, or breathing and, or circulation problems usually associated with skin or mucosal changes. *Patients having an anaphylactic reaction should be treated using the Airway, Breathing, Circulation, Disability, Exposure (ABCDE) approach. *Anaphylactic reactions are not easy to study with randomised controlled trials. There are, however, systematic reviews of the available evidence and a wealth of clinical experience to help formulate guidelines. *The exact treatment will depend on the patient's location, the equipment and drugs available, and the skills of those treating the anaphylactic reaction. *Early treatment with intramuscular adrenaline is the treatment of choice for patients having an anaphylactic reaction. *Despite previous guidelines, there is still confusion about the indications, dose and route of adrenaline. *Intravenous adrenaline must only be used in certain specialist settings and only by those skilled and experienced in its use. *All those who are suspected of having had an anaphylactic reaction should be referred to a specialist in allergy. *Individuals who are at high risk of an anaphylactic reaction should carry an adrenaline auto-injector and receive training and support in its use. *There is a need for further research about the diagnosis, treatment and prevention of anaphylactic reactions.

To analyse 2 years of experience after introducing automated external defibrillators (AED) all over Austria. ⋯ Compared to historical data, short 'intervals to shock' delivery and the frequent start of basic life support resulted in an increased hospital discharge rate in good neurological condition. Despite the relatively high number of installed devices, the number of patients reached remained small.
