A case of cryptococcoma of the right upper lobe producing tracheal obstruction during anaesthesia is reported. Whilst conscious the patient breathed spontaneously with little difficulty. The reasons underlying complete tracheal obstruction during anaesthesia are discussed.

Thirty consecutive cases of portal hypertension seen in a surgical unit in Lusaka, Zambia, are reported. Of these cases 70% were due to portal fibrosis caused by Schistosoma mansoni infestation. Portacaval shunting was undertaken in most cases. Patients with portal fibrosis responded more favourably to portal decompression than did patients with cirrhosis. It is probable that the condition is more common than is generally reconigzed in areas where S. mansoni infestation is endemic.

A double-lumen tube with a mercury weight attached to its distal end was positioned in the small intestine of six subjects who were to undergo an elective laparotomy. The tube and the technique for its localization were exactly similar to those used in previous intestinal perfusion experiments. Marked ;concertinaing', or gathering of the small intestine proximal to the mercury weight, was seen at laparotomy in all six subjects. The ratio between the mean intestinal length from the mercury weight to the ligament of Treitz after removal of the tube to that with the tube in situ was 3.0 (2.5-3.8). Mean total jejuno-ileal length was 421 (320-521) cm. In five of the six subjects the distal end of the tube was more than half way between the ligament of Treitz and the ileo-caecal valve although it was only 100-120 (mean 108) cm from the incisor teeth. Segmental perfusion studies of the human jejunum involve a much longer length of small intestine than is generally assumed-by a factor of approximately 3. Such studies assess absorption rates over a substantial proportion of the small intestine and are not confined to a short segment of proximal jejunum. The nutritional significance of such studies in which amino acids, peptides, and carbohydrates are investigated is increased. Studies designed to measure absorption rates from the ileum should be treated with caution as part or all of the perfusion segment may be past the ileo-caecal valve.

It is noted that whilst death from venomous snake bites in this area is not common, serious permanent disability may occur. The lesions which may follow venomous bites are described and the management of the late complications discussed. Emergency treatment is not considered. The importance of early grafting in the prevention of permanent disability where there is serious tissue distruction, is emphasised. (AU)
