Haemolytic-uraemic syndrome outbreak caused by Escherichia coli O111:H-: clinical outcomes.

In South Australia in 1995, we treated 20 children with haemolytic-uraemic syndrome associated with Escherichia coli O111:H-. The source of the outbreak was contaminated locally produced semi-dry fermented sausage (mettwurst). One child died of multiple haemorrhagic cerebral infarcts. Eighteen children required renal dialysis (for a median of 14 days); 12 months after discharge five still had significant impairment of renal function. Other major complications included colonic necrosis (3), cerebral haemorrhage/infarction (3), convulsions (4), and glucose intolerance (2). Although E. coli O111:H- has been associated with sporadic cases of haemolytic-uraemic syndrome, this was the first large outbreak reported in Australia.

Bowel habits of healthy Australian children aged 0-2 years.

OBJECTIVE: To define the bowel habits of healthy Australian children aged up to 2 years. METHODOLOGY: One hundred and forty children were recruited in six age categories with a minimum of 20 children per category. Data on bowel habit was recorded by parents daily for 1 week. RESULTS: Stool frequency decreased with age. Ninety-five per cent of infants 0-14 days passed more than two stools per day compared with 21% at age 13-24 months. Breastfed infants passed more frequent and looser stools than children fed infant formula and solids and also showed a wider variation in frequency. CONCLUSIONS: Mean stool frequency decreased with age as did the variation. This is a combined effect of age and feed type. These data can be used as a guide to the bowel habit of healthy Australian children.
