Clarification

In the December 15, 1997, issue of Infectious Disease Alert, the first sentence of the synopsis of the "‘Pneumaturia’ in a Diabetic Patient: What to do About Air in the Urine" article should have begun: "Emphysematous cystitis is an unusual . . ." The last sentence of the article should also have read: "In summary, emphysematous cystitis is an unusual . . ." We apologize for any confusion this may have caused.

In the January 1, 1998, issue of Infectious Disease Alert, the article "Can HIV Infection Be Cured?" appeared on pages 49-51. The second paragraph of the commentary should have read:

Vila and colleagues previously reported two patients who started treatment with ddI and hydroxyurea for one year beginning three and 12 months after HIV infection and one year after discontinuation of treatment, who had no apparent evidence of viral replication in peripheral blood or in lymph nodes (Vila J, et al. Lancet 1997;350:635-636). However, proviral DNA remained detectable in both patients. Based on the observations reviewed here, it seems likely that both patients also probably still had replication competent virus present. A similar case, treated with indinavir, ddI, and hydroxyurea, was reported by Franco Lori (Cohen J. Science 1997;277:1927). —sd
