Infection with herpes simplex virus (HSV) is extremely common worldwide. In immunocompromised patients anogenital HSV disease may have atypical features and may be very severe. Treatment of aciclovir-resistant anogenital HSV disease is challenging, as resistance to alternative treatments may occur, and effective treatment generally involves intravenous therapy with relatively toxic agents such as foscarnet. This case report presents three immunocompromised patients with presumed aciclovir-resistant anogenital HSV disease who were successfully treated with topical imiquimod. Imiquimod promotes local immune activation, which results in resolution of viral lesions such as anogenital warts and HSV disease. It is convenient to use and avoids the necessity for intravenous treatment with substantial systemic toxicity. In addition, as the mode of action of imiquimod is related to immune stimulation rather than direct antiviral activity, it may be used repeatedly without resistance developing.
Following a rise in cases of infectious syphilis in New Zealand, national enhanced surveillance at sexual health clinics was initiated. All public sexual health clinics reported monthly on the number of cases seen, and completed a coded questionnaire on each case. Monthly reports to routine surveillance were compared and discrepancies reconciled. During 2011, 72 cases of infectious syphilis were reported. The majority (83%) were among men who have sex with men who were mainly infected in New Zealand and had an ethnic profile similar to all New Zealanders. Most heterosexual infections occurred overseas, among people of non-European non-Maori ethnicity. About half the cases had symptoms on presentation. Overall, 18% of men who have sex with men were HIV positive. Resurgent syphilis in New Zealand disproportionally affects men who have sex with men, amongst whom HIV is prevalent. Men who have sex with men should be aware of the risks and symptoms of syphilis and encouraged to have regular sexual health checks including serology testing. Control of syphilis should be included in the strategy to check HIV spread. Syphilis serology should continue to be part of routine immigration and antenatal screening, and where clinically indicated. Enhanced surveillance was easily initiated for an uncommon condition seen at sexual health clinics, and provided valuable information.
Abstract.We instigated an enhanced voluntary surveillance system to determine the epidemiology of infectious syphilis in Auckland because it is not a notifiable condition. The study took place over a 12-month period from July 2006 to July 2007. We identified 92 cases of infectious syphilis, of which 71 were male (77%). Forty-four (48%) cases were in men who have sex with men, who made up the biggest proportion. Forty-eight cases (52%) acquired their infection in New Zealand and only 48 of all identified cases were symptomatic (52%). Our results confirm that infectious syphilis incidence is currently under-reported.Additional keywords: congenital syphilis, men who have sex with men.
Women diagnosed with usual type VIN which resolves spontaneously are very young, mainly non-European, and usually present with multiple, asymptomatic pigmented lesions. HPV genotypes and their frequencies are similar to those detected in older women with usual type VIN. This clinically defined group of women may be managed by observation alone if follow-up is assured.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
