Further to the discussion of anaemia (anemia to our US readers) and insufficient milk. Catherine Fetherston, Perth Australia presented her study of risk factors for mastitis at the ALCA Conference in Hobart. She reported on three variables excluded from the logistic regression because of low numbers of cases (<10%). Of ten women in the study who reported having anaemia, eight developed mastitis. Given the reluctance to do blood transfusions these days, we see more women going home from hospital anaemic after postpartum blood loss. I personally think that Sheehan's syndrome is very rare, and that we are seeing other effects on lactation caused by either blood loss or anaemia. I think this area needs further study. The other two excluded variables? Ten women reported using a nipple airer, nine of whom developed mastisis. Five reported the baby had a tied frenulum, all five developed mastitis.
