HPV-based screening increases colposcopies at the first round, but also strongly increases the detection rate. At the second round, HPV prevalence was much lower and the detection rate also fell, corroborating the need for longer screening intervals in HPV-negative women.

Although herpes zoster (shingles) can occur in anyone with a history of chickenpox, it is more prevalent and usually more severe in older patients (i.e. persons over 50 years of age). While the cutaneous manifestations of shingles usually resolve in approximately 4 weeks, the pain can persist for several months, or even years in the untreated patient. This pain following healing of the skin, termed post-herpetic neuralgia (PHN), can be very severe. Three well tolerated and effective antiviral drugs are available for the therapy of acute herpes zoster. The nucleoside analogues, aciclovir, famciclovir and valaciclovir, appear to shorten the duration of PHN to a similar degree, but none affects the incidence of PHN. Aciclovir is taken 5 times daily for 7 days, while famciclovir is taken 3 times daily for 7 days. Valaciclovir, the L-valyl ester of aciclovir, when taken orally, produces plasma levels of aciclovir equivalent to those seen following intravenous administration of aciclovir. Valaciclovir has not only been proved to be more efficient than aciclovir (i.e. 3 times daily administration) but also more effective than aciclovir in shortening the duration of PHN. Current studies are determining the relative efficacy of valaciclovir versus famciclovir. Presently, a fourth drug, sorivudine, is being compared with aciclovir for the therapy of acute herpes zoster in older patients, but data from these trials are not yet available. Corticosteroids have been used to treat herpes zoster for much longer than the antiviral drugs, but the effect of corticosteroids on PHN does not appear to be consistent. Corticosteroids plus aciclovir did not provide an added benefit over aciclovir alone in one study but this combination did appear to improve the quality of life of older patients in another investigation. The recent availability of the varicella zoster vaccine may cause shingles to be an uncommon and/or mild disease by the mid twenty-first century. Meanwhile, the search continues for more effective and efficient therapies for acute herpes zoster with the primary goal in older patients to affect the most important sequela of zoster in this population, PHN.
