Review Case ReportsFatal systemic air embolism during endoscopic retrograde cholangio-pancreatography.
Air embolism is a rare complication of gastrointestinal endoscopy. We present a 56-year-old male who developed both venous and systemic arterial air embolism during an endoscopic retrograde cholangiopancreatogram. ⋯ Clinical diagnosis of air embolism during endoscopy is difficult and urgent echocardiography is the investigation of choice. Treatment is largely supportive but hyperbaric oxygen therapy should be considered in any severe cases, especially if neurological injury is present.

ReviewSpinal cord stimulation in chronic pain: a review of the evidence.
This review looks at the evidence for the effectiveness of spinal cord stimulation in various chronic pain states. Spinal cord stimulation can only be effective when appropriate dorsal column fibres in the spinal cord are preserved and able to be stimulated. Spinal cord stimulation has been shown to have little to offer for patients with some diagnoses. ⋯ There is a lack of high quality evidence relating to spinal cord stimulation due to difficulties in conducting randomized controlled trials in this area. Serious methodological problems are encountered in blinding, recruitment and assessment in nearly all published trials of spinal cord stimulation. Suggestions regarding appropriate methodologies for trials which would produce better quality evidence are summarized.

Review Case ReportsPleural puncture: an unusual complication of a thoracic epidural.
Thoracic epidural analgesia is a common method of pain relief for major thoracic and abdominal surgery. Numerous complications may occur, including temporary or permanent neurological injury. A rare and potentially life-threatening complication of thoracic epidural analgesia is pleural puncture by the needle or the catheter. Such a case is presented and pleural puncture in association with attempted thoracic epidural catheter placement is discussed.

The ability of intensive care to replace or support vital organ function has resulted in some patients surviving for long periods of time without improvement or a terminal event. In patients with no realistic chance of survival, decisions to withdraw or withhold life-sustaining therapies are commonly made. Withdrawal of life support at the patient's request is lawful at common law and, in some states of Australia, by legal statute. ⋯ However much weight is frequently placed on the wishes of the family. Disagreements between family and clinicians over decisions to withdraw therapy are unusual and generally resolve over time. However if disagreement persists, it may be advisable to apply to the courts for a declaratory judgement, given the tenuous legal basis of withdrawal of life-sustaining therapy in Australia and the uncertainty over the courts' view of the role of the patient's family in the decision-making process.
