Spread of steroid-containing foam after intrarectal administration.
The spread of a steroid-containing foam from the rectum was studied in eight normal controls and eight patients with ulcerative colitis proved by biopsy. A standard dose of foam was labelled with technetium-99m adsorbed on to microspheres of Amberlite resin. Immediately after the foam was administered the extent of spread varied considerably, though in no instance did it extend beyond the rectosigmoid. Further scans at 120 and 240 minutes showed no further spread. It is concluded that a steroid-containing foam has a topical effect only on the rectal mucosa.

The reproducibility of the station pullthrough technique for measuring lower oesophageal sphincter pressure.
The results are presented of two studies of the station pullthrough technique for lower oesophageal manometry. The first part of the work is an assessment of the reproducibility of this technique using both an infused tube system and a system of subminiature, intraluminal strain gauge transducers. The second part of this report describes a study into the effect that the position of the recording hole on the probe may have in relation to the measured pressure for the lower oesophageal sphincter.

Isolated perforation of the gall bladder following blunt abdominal trauma.
Isolated perforation of the gall bladder as a consequence of blunt abdominal injury is rare. A single case is described which illustrates several features which may characterize this lesion.

Carcinoid tumour as a complication of ulcerative colitis.
Patients with long-standing ulcerative colitis have an increased chance of developing a carcinoma of the colon, especially when the inflammatory process involves the entire colon, but no case of a carcinoid tumour of the colon occurring in a patient with ulcerative colitis has been reported.
