Effect of storage and heat on antimicrobial proteins in human milk

Human milk, after storage and pasteurisation at 73 degrees C for 30 minutes at a milk bank, was found to have little surviving IgA, IgG, lactoferrin, lysozyme, and C3 complement. Accurate pasteurisation at 62.5 degrees C produced a loss of 23.7% of the lysozyme, 56.8% of the lactoferrin 34% of the IgG, but no loss of IgA. Storage by deep freezing at -20 degrees C for 3 months produced no appreciabile loss of lactoferrin, lysozyme, IgG, IgA, or C3.

Failure to thrive at the breast: an old problem revisited

Four apparently normal breast-fed infants failed to thrive when fed on demand. They all shared a tendency to accept long intervals between feeds from birth. Infant welfare clinics should be alerted to this problem. If infants who attend these clinics are accurately weighed and their progress carefully recorded on weight charts this insidiously developing complaint could be detected earlier and with appropriate advice, a potentially serious condition averted.

Congenital cytomegalovirus infection after maternal renal transplantation

Congenital cytomegalovirus infection was found in an infant whose mother had a successful renal transplant and was treated with immunosuppressant therapy before and during pregnancy. Although so far not experiencing any untoward infections, the child had impaired T-lymphocyte function and subnormal serum-IgA.
