Despite considerable information and discussion about the risk of serious complications in patients with systemic mastocytosis undergoing general anaesthesia, little is known specifically about the risk to patients with isolated cutaneous mastocytosis. The experience of 29 general anaesthetics in 12 children with urticaria pigmentosa and three with solitary cutaneous mastocytoma was reviewed. No major complications were encountered and the four minor problems seen were self-limiting. The data from this study do not suggest that patients with urticaria pigmentosa or solitary cutaneous mastocytoma are at increased risk of life-threatening complications under general anaesthesia.

Case Reports
Combined unilateral high frequency jet ventilation and contralateral intermittent positive pressure ventilation.
The anaesthetic management of a patient who required right lower lobectomy for bronchial carcinoma associated with emphysema, pneumoconiosis and a previous thoracoplasty for pulmonary tuberculosis, is described. A technique of unilateral high frequency jet ventilation plus conventional intermittent positive pressure ventilation to the contralateral lung was used.

An exercise in quality assurance during neuroanaesthetic procedures identified uncontrolled re-use of armoured latex rubber tracheal tubes as a risk factor associated with equipment failure. We recommend that such tubes should be used once only. Alternatively, tubes made from more stable materials, such as polyvinyl chloride and silicone rubber, are available for clinical evaluation.
