Ecstacy-induced delayed rhabdomyolysis and neuroleptic malignant syndrome in a patient with a novel variant in the ryanodine receptor type 1 gene.

We present the case of a 20-year-old woman who developed rhabdomyolysis, disseminated intravascular coagulopathy and multi-organ failure induced by ecstasy. Following initial improvement, she developed delayed rhabdomyolysis then haloperidol-induced neuroleptic malignant syndrome, which was treated with a total of 50 mg.kg(-1) dantrolene. Subsequent genetic testing revealed a novel potentially pathogenic variant in the ryanodine receptor type 1 gene. However, caffeine-halothane contracture testing of the patient's mother who carried the same gene variant was negative for malignant hyperthermia.

In situ hypothermic liver preservation during radical liver resection with major vascular reconstruction.

BACKGROUND: The in situ hypothermic liver preservation technique may allow a more aggressive approach to tumours of the caval confluence and/or all three hepatic veins, which would otherwise be deemed irresectable. METHODS: All descriptive data regarding patient demographics, operative characteristics, perioperative complications and outcomes of nine patients in whom this technique was used were collected prospectively. RESULTS: Seven patients underwent liver trisegmentectomy and two had primary retrohepatic venal caval resection. Total hepatic vascular occlusion with in situ hypothermic liver preservation was used for venous reconstruction in all patients. The vena cava was reconstructed with prosthetic graft in seven patients. All main hepatic veins were reconstructed in the seven liver resections. In situ hypothermic liver preservation was well tolerated as evidenced by preserved hepatic synthetic function early after operation. One patient died 66 days after surgery. There were two recurrences after a median follow-up of 14 (range 2-33) months; local recurrence was identified in one patient after 4 months and distant metastasis in another after 8 months. CONCLUSION: The in situ hypothermic liver preservation technique appears to be a useful adjunct to radical hepatobiliary tumour excision procedures that require total hepatic vascular exclusion and major vascular reconstruction.

Neuromuscular blockers--a means of palliation?

As we die, our respiratory pattern is altered and we seem to gasp and struggle for each breath. Such gasping is commonly seen as a clear sign of dyspnoea and suffering by families and loved ones, however, it is unclear whether it is perceived at all by the dying person. Narcotics and sedatives do not seem to affect these gasping respirations. In this issue of the Journal of Medical Ethics, we are asked to consider whether the last gasp of a dying patient could be or, perhaps, even should be avoided by administering neuromuscular blockers to palliate dying patients. For many reasons, such as our current failure to alleviate pain and distress, stories of inadequate analgesia and sedation in critically ill paralysed patients and the inability to know the intent-whether to palliate or to euthanise-it would seem that administering neuromuscular blockers should not be ethically permissible.

Analgesia, virtue, and the principle of double effect.

The principle of double effect is widely used to permit the administration of narcotics and sedatives with the intent to palliate dying patients, even though the administration of these drugs may cause hastening of death. In recent medical literature, this principle's validity has been severely criticized, causing health care providers to fear providing good palliative care. Most of the criticisms levelled at the principle of double effect arise from misconceptions about its purpose and origins. This discussion will explore how virtue-based ethics can overcome the most important challenge to the principle of double effect's validity, that of its reliance on intention to determine whether the administration of analgesia is ethically acceptable.
