Survival of patients with traumatic rupture of the thoracic aorta (TRTA) depends on early surgical repair. Six cases of TRTA were treated at our institution in 7 years. Time to diagnosis was 1.5, 3, 4, 36, 91 and 140 hours (mean = 46 hours). ⋯ Significant delay in diagnosis and treatment occurred in three patients. The reasons for delay were unrecognized signs for TRTA on the initial chest X-ray, a false-negative result of transoesophageal echography and not considering the diagnosis of TRTA. The diagnosis of TRTA requires a high index of suspicion and should always be considered in victims of high impact trauma.

Case Reports
Hyperosmolar diabetic non-ketotic coma, hyperkalaemia and an unusual near death experience.
Generally, cardiac arrest due to pulseless electrical activity has a poor outcome, except when reversible factors such as acute hyperkalaemia are identified and managed early. Hyperosmolar diabetic non-ketotic coma may lead to acute hyperkalaemia. Hyperosmolar diabetic non-ketotic coma is a metabolic emergency usually seen in elderly non-insulin dependent diabetics, characterized by severe hyperglycaemia, volume depletion, altered consciousness, confusion and less frequently neurological deficit. ⋯ Hyperosmolar diabetic non-ketotic coma should be considered in any patient with altered consciousness or neurologic deficit in conjunction with hyperglycaemia. As hyperosmolar diabetic non-ketotic coma results in severe fluid depletion, electrolyte disturbance, profound hyperglycaemia and an altered mental state, the guiding principles of therapy include aggressive rehydration, insulin therapy, correction of electrolyte abnormalities and treatment of any underlying illnesses. Treatment of acute hyperkalaemia includes calcium ions, insulin with dextrose, salbutamol and haemodialysis.

The principles of the management of upper cervical injuries remain controversial. The specific anatomical conditions render upper cervical injuries more problematic than lower cervical injuries. Here we present and discuss our experiences with upper cervical injury, comparing them with other treatment modalities. ⋯ All patients showed stable fracture healing and experienced no additional clinical disability on follow-up after a minimum of 3 months, except one who died due to cardiac and respiratory failure. Regardless of the type of injury, indication for surgery in many cases of upper cervical injury is neurological abnormality associated with radiologically observed neural compression. It is our belief that, in the absence of both neurological abnormality and compression to neural structures observed in CT/MRI, treatment with the Philadelphia collar alone is safe, cost-effective and easily applicable for many cases of upper cervical injury.

We present a retrospective review of Hantavirus infection in the emergency department. Thirteen cases of Hantavirus infections with renal syndrome from July 1989 to August 1999 were analysed. The diagnosis was confirmed by detection of Hantavirus antibodies in all cases. ⋯ Only one patient in our series had to be dialysed. Hantavirus disease should be included in the differential diagnosis of acute renal failure with thrombocytopenia, particularly in patients with suspected exposure in known endemic areas. The differential diagnosis of any perplexing case of undifferentiated febrile illness with acute renal failure and thrombocytopenia should include Hantavirus infection.
