Dr C. Peter N. Watson has been the chief editor of two essential editions on herpes zoster and postherpetic neuralgia. He is a neurologist in the Department of Medicine, Division of Neurology, University of Toronto, Ontario, Canada. Dr Watson published the first well-conducted trial in postherpetic neuralgia of amitriptyline as an analgesic independent of its effects on depression. Dr Watson enjoys an international reputation for that paper and his other contributions in the same field. These include the two well used volumes Herpes Zoster and Postherpetic Neuralgia, which he both edited and wrote a considerable part of (Watson, 1993; Watson & Gershon, 2001). He wrote the chapter on this topic for Bonica’s textbook (3rd edition) and in The Textbook of Pain. His seminal study on amitriptyline was followed by a series of pioneering or definitive trials of other oral medications in postherpetic neuralgia, including maprotiline (1992), nortriptyline (1998), and oxycodone (1998). Dr Watson has received the Canadian Pain Society’s highest honour, the Distinguished Career Award, in 2003, and the medal of the Varicella Zoster Research Foundation, in 2007, for his pioneering research on postherpetic neuralgia.Dr Anne A. Gershon is a Professor of Pediatrics at Columbia University College of Physicians and Surgeons. She is a graduate of Cornell Medical School. Her research over the past 40 years has included epidemiology, diagnosis, immunology, latency, prevention, and treatment of varicella and zoster. Her studies with varicella vaccine were critical for its licensure in the United States. She is continuing to study the safety and efficacy of varicella vaccine in the “vaccine era”. She has also focused on HIV infection in children, particularly opportunistic infections. She has received research funding from NIH for the past 40 years. Dr Gershon has served on numerous national and international medical committees. She was President of the Infectious Diseases Society of America (IDSA) in 2009. She has received many professional awards including the Gold medal of the Sabin Vaccine Institute and the Fleming Award of the IDSA. She is the author of over 300 publications and has edited 11 books.Dr Michael N. Oxman is Professor of Medicine and Pathology at the University of California, San Diego and Sta? Physician in Infectious Diseases at the Veterans A?airs San Diego Healthcare System. He pioneered the use of large double-blind placebo-controlled multi-centre trials to evaluate treatment and prevention of HSV and VZV infections. A student of herpes zoster for 50 years, Dr Oxman led the landmark Shingles Prevention Study, which demonstrated the e?cacy of live attenuated VZV Oka zoster vaccine leading to its licensure and routine use in the US and other countries to prevent herpes zoster and postherpetic neuralgia. Dr Oxman is a recipient of the VZV Research FoundationLifetime Achievement Award, the Plenary Lectureship honouring Professor Michiaki Takahashi at the 10th Annual Meeting of the Japanese Society of Vaccinology, the Stephen E. Straus Memorial Lectureship in Infectious Diseases at the NIH, the Abraham I. Braude Visiting Professorship at UCSD, and the Department of Veterans A?airs John Blair Barnwell Award for outstanding scienti?c achievements in clinical research.
