The aim of this study was to investigate whether the incidence of headaches following myelography could be reduced by using a needle with an atraumatic tip. 107 patients were studied in a trial of 22 gauge atraumatic versus 22 gauge bevel tipped needles. In the first 3 days after myelography, there was a significant reduction in the incidence of headaches in patients in whom an atraumatic needle had been used.

The diagnosis of visceral perforation during pregnancy is often delayed and the management complex. A 32-year-old primigravid woman in her second trimester presented with abdominal pain and a pre-existing ileoanal pouch. Initial imaging was negative but later imaging was suggestive of serious pathology. At laparotomy, a caesarean section was performed. Peritonitis was encountered secondary to two discrete perforations in the small bowel separate from her pouch. Histology found an ischaemic perforation secondary to a pressure effect from the gravid uterus. In pregnancy, ileoanal pouches may make the interconnected bowel vulnerable to the pressure effect of the gravid uterus and perforation. Pregnant women with such a surgical history who develop symptoms suggestive of bowel perforation should have rapid imaging and their clinical team should consider early definitive surgical intervention.
