Different tissues or body fluids in which human immunodeficiency virus type 1 (HIV-1) can reside may contain viruses with distinct characteristics. Sixteen HIV-1-infected patients receiving zidovudine or didanosine were studied cross-sectionally and 1 patient who switched from zidovudine to didanosine was followed sequentially to determine if drug(More)
BACKGROUND The brief period of viral replication in recurrent herpes labialis lesions suggests shorter therapeutic regimens are a logical episodic treatment strategy. OBJECTIVE We sought to assess the efficacy and safety of single-dose and single-day famciclovir treatments. METHODS In all, 701 randomly assigned patients self-initiated therapy with(More)
The circulation of poor-quality medicines continues to undermine the fight against many life-threatening diseases. Anti-malarial medicines appear to have been particularly compromised and present a major public health threat in malaria-endemic countries, negatively affecting individuals and their communities. Concerted collaborative efforts are required(More)
BACKGROUND The Bolivian northern Altiplano is characterized by a high prevalence of Fasciola hepatica infection. In order to assess the feasibility, safety and efficacy of large-scale administration of triclabendazole as an appropriate public health measure to control morbidity associated with fascioliasis, a pilot intervention was implemented in 2008.

OBJECTIVE Many cases of herpes simplex virus (HSV) infection occur through asymptomatic shedding from persons without evidence of clinical disease. This study explores whether famciclovir reduces HSV shedding in HSV-2 seropositive persons with or without a history of symptomatic genital herpes. STUDY DESIGN One hundred twenty-seven HSV-2 seropositive(More)
BACKGROUND Orally administered antiviral therapy for genital herpes improves the time to lesion healing and resolves symptoms during an outbreak. Although traditional therapy for a recurrent episode for healthy adults has consisted of twice-daily dosing for 5 days, recent studies have indicated that shorter courses of antiviral therapy are effective. This(More)
BACKGROUND Recurrent otitis media and acute otitis media treatment failure are commonly encountered in the pediatric population. OBJECTIVE To compare the clinical efficacy of gatifloxacin with amoxicillin/clavulanate for the treatment of acute otitis media treatment failure and recurrent otitis media. METHODS Three hundred fifty-four children 6 months-7(More)
In malaria-endemic countries, large proportions of infected individuals are asymptomatic, constituting a reservoir of parasites for infection of newly hatched mosquitoes. This study evaluated the impact of screening and treatment of asymptomatic carriers of Plasmodium falciparum. Eighteen villages were randomized (1:1) to study arms and inhabitants(More)
BACKGROUND Because of concerns about arthrotoxicity, fluoroquinolones are restricted for use in children. This study describes the safety and efficacy of gatifloxacin when used for treatment of children with recurrent acute otitis media (ROM) or acute otitis media (AOM) treatment failure (AOMTF). METHODS We performed an analysis of 867 children included(More)
BACKGROUND Recurrent genital herpes is a major problem for patients worldwide. Early episodic treatment with short-course therapy is effective, often stopping progression of outbreaks. This study is the first head-to-head comparison of single-day famciclovir (1000 mg administered twice daily) versus 3-day valacyclovir (500 mg administered twice daily) for(More)
