To evaluate the usefulness of a real-time PCR for Leishmania DNA in the diagnosis and follow-up of patients with human immunodeficiency virus type 1 (HIV-1) and Leishmania coinfection, Leishmania DNA levels were measured in whole peripheral blood from 25 HIV-infected patients with clinical features suggestive of visceral leishmaniasis. Leishmania DNA was(More)
Although malaria in pregnancy can cause very significant neonatal morbidity, congenital malaria is a very rare condition in both endemic and non-endemic areas. A case of congenital malaria by Plasmodium vivax, initially mistaken for neonatal sepsis, is described. The correct diagnosis was accidentally done, as congenital malaria had been missed in the(More)
The development in Plasmodium falciparum of the resistance to chloroquine (CQ) constitutes a public health priority, due to its direct influence in childhood mortality. The molecular basis for CQ resistance (CQR) is still unclear but, recently, a new relevant gene, named pfcrt, with several point mutations was identified in P. falciparum. Two mutations,(More)
The present study aimed to compare the diagnostic performance of different European reference laboratories in diagnosing helminths and intestinal protozoa, using an ether-concentration method applied to sodium acetate-acetic acid-formalin (SAF)-preserved faecal samples. In total, 102 stool specimens were analysed during a cross-sectional parasitological(More)
A cluster of 22 imported malaria cases, 21 caused by Plasmodium falciparum, was observed among illegal Chinese immigrants in northern Italy in the summer of 2000. The rate of severe disease was high because the patients were not immune and they sought health-care services late in their illness because of their clandestine status. Recognition of the outbreak(More)
course and the role of Shiga toxin–pro-ducing Escherichia coli infection in the hemolytic-uremic syndrome in pediatric patients, 1997–2000, in Germany and Austria: a prospective study. To the Editor: Chikungunya virus (CHIKV) infection is a self-limiting illness characterized by fever, headache, weakness, rash, and arthral-gia. Some patients have prolonged(More)
Soil-transmitted helminth (STH) infections represent a major public health problem in poor and developing countries. During the period September-October 1998 we conducted an epidemiological survey of STH infections in schoolchildren of an urban area (group A) and an indigenous reserve (group B), in the Municipality of Ortigueira, State of Paranà, Brazil, to(More)
Malaria is a common, life-threatening infection in endemic tropical areas and one that presents a diagnostic challenge to laboratories in most non-endemic countries. A rapid and accurate diagnosis is a prerequisite for effective treatment, especially for the potentially fatal cases of Plasmodium falciparum infection. In the present, multi-centre study, the(More)
BACKGROUND Treatment options for anogenital warts in patients with HIV-1 are unsatisfactory because they fail to eradicate latent human papillomavirus. GOAL To determine tolerability and efficacy of topical 1% cidofovir cream for the treatment of external anogenital warts in HIV-infected patients. STUDY DESIGN A randomized, placebo-controlled,(More)
An increasing proportion of malaria cases in Italy is observed in immigrants revisiting their country of origin, but little specific research work has been carried out in this field. All malaria cases occurring from 1990 to 1998 at the Reference Clinic for Infectious and Tropical Diseases in Brescia were prospectically evaluated to compare clinical outcome(More)
