Private cord blood banks continue to advertise their services to couples expecting a child. Cord blood can be stored safely for many years. Public cord blood banks accept collections only from affiliated hospitals (Medical Letter 2001; 43:84). Units are available for any patient; there is no guarantee that a particular donor's blood will be available if the donor or a family member needs a stem cell transplant. Many patients can find an unrelated match in a public cord blood bank, but members of minority ethnic groups are often more difficult to match (www.marrow.org). Private cord blood banks...

Medical Letter consultants have brought to our attention some confusion that has accompanied the release of Adacel, a combination of tetanus toxoid, diphtheria toxoid and acellular pertussis antigens (Tdap) recently approved for use as a booster in adolescents and adults 11-64 years old (Med Lett Drugs Ther 2006; 48:5).

In the recent Medical Letter article on the treatment of Clostridium difficile–associated disease (CDAD) we wrote: “Healthcare workers caring for patients with C. difficile infection should follow contact isolation precautions, especially use of gloves and hand washing with soap and water after glove removal.
