Comparative StudyLack of agreement between two methods of measuring haemoglobin.
Haemoglobin values are reported by the current generation of blood gas analysers used in many intensive care units. A comparison of one such machine against a reference found that there was a mean difference of 1.32 g/dL (95% confidence intervals -2.75-0.9 g/dL) between the values reported. Haemoglobin values reported by blood gas machines may be inaccurate.

Case ReportsColloid cyst of the 3rd ventricle as a cause of acute neurological deterioration and sudden death.
A 13 year old girl presented with a 24 h history of headache and vomiting. There were no focal neurological signs. The diagnoses considered were vascular headache, meningitis and subarachnoid haemorrhage. ⋯ In this case, it is considered that lumbar puncture may have hastened death by increasing brain-stem compression due to cerebellar tonsillar herniation. It raises the question of whether cerebral CT scan, where readily available, should be performed prior to lumbar puncture. Pathologically, colloid cysts may be easily missed if the brain is examined fresh as the cysts are fragile and have a tendency to be destroyed or fall out.
