Comparison of physical and flow characteristics of "streamline" and "normal" cuffed tracheal tubes.
A comparative study was undertaken of the physical and flow characteristics of "streamline" cuffed tracheal tubes (SCT; Medishield) and "normal" cuffed tracheal tubes (NCT) of sizes 6.0, 6.5, and 9.0 mm. The embedding of the pilot tube within the wall of SCT imparts a D-shaped lumen which is more marked in 6.0- and 6.5-mm tubes. As a result, there is a 15% reduction in the lumen of a 6.5-mm SCT. All sizes of SCT studied had a smaller outer diameter compared with the corresponding sizes of NCT and thus occupied less space in the trachea. In sizes 6.0 and 6.5 mm, the SCT was found to have distinct disadvantages, such as increased resistance to ventilation of up to twice that of NCT, and turbulent flow even at a minute volume of 5 litre min-1. SCT, size 9.0 mm, however offered marginally less resistance compared with NCT of the same size.

Anaesthetic management of achondroplasia.
We report a patient with achondroplasia who presented for emergency Caesarean section. Endotracheal intubation was not difficult. The reaction of this patient to drugs such as thiopentone and tubocurarine, judged on body weight basis, was normal.

Pathology of rabies: a light- and electron-microscopical study with particular reference to the changes in cases with prolonged survival.
Light- and electron-microscopical studies were conducted on necropsy material from six cases of rabies encephalitis including three with the unusual feature of surviving for over 14 days as a result of intensive medical care. This included administration of antiviral agents and interferon inducers and prevention of hypoxia by intermittent positive pressure ventilation. In all these cases, typical Negri bodies were demonstrated. Inflammatory reaction was absent or minimal. Unlike the cases with short survival where Negri bodies were infrequently seen and restricted mostly to the hippocampus, in cases with prolonged survival, they were present in large number, widely distributed throughout the grey matter of the brain. The associated inflammatory reaction in these cases, however, did not keep pace with the increase in number of inclusion bodies. Peripheral neuritis was observed in two of these cases, which also showed myelitis involving the cervical region and inflammation of dorsal root ganglia. One of them showed necrosis and severe inflammation of the lower cervical sympathetic ganglion. An electron-microscopical study conducted in four cases showed three forms of the inclusion body in the cytoplasm of neurons.

Accidental intravenous injection of cetrimide. A case report.
An unusual case of cetrimide toxicity, probably the first of its kind to be recorded, is reported. It occurred after accidental intravenous injection in an infant and the management is discussed. Cardiac arrest, muscle paralysis, haemolysis and other complications were successfully treated.
