We aimed to estimate the diagnostic latency of patients with visceral leishmaniasis (VL). A monocentric retrospective observational study was conducted including all confirmed cases of VL diagnosed from January 2005 to March 2022. Epidemiological and clinical characteristics of patients with VL were collected.

Chagas disease prevalence among migrants from El Salvador in Milan: a cross- sectional study of an often-overlooked population.

Background: Chagas disease (CD) is considered to be highly endemic in El Salvador, where its prevalence is estimated to be 1.3-3.7%.

Family cluster of Chagas disease among Bolivian immigrants in Italy: High rate of maternal-fetal transmission.

Background: Chagas disease (CD) or American trypanosomiasis is a neglected anthropozoonosis caused by Trypanosoma cruzi that affects 6-8 million people worldwide (mainly in Latin America), 30-40% of whom develop cardiac or digestive complications. Once confined to endemic areas of Latin America, CD has more recently become a global disease as a result of migration flows from endemic to non-endemic regions, particularly in northern America and Europe. Congenital transmission is a particular challenge as it may be sustained for multiple generations and perpetuate the infection even in non-endemic countries.

Loop-mediated isothermal amplification (LAMP) assay for the diagnosis of imported malaria: a narrative review.

Loop-mediated isothermal amplification (LAMP) is a molecular method to detect malaria recently introduced in the market. LAMP is simple to perform and does not require advanced equipment and training thus satisfying the qualification as a point-of-care diagnostic screening test. In this narrative review, we focus on the role of LAMP for malaria diagnosis in non-endemic settings.

Elucidating the 3D Structure of a Surface Membrane Antigen from as a Serodiagnostic Biomarker of Chagas Disease.

Chagas disease (CD) is a vector-borne parasitosis, caused by the protozoan parasite , that affects millions of people worldwide. Although endemic in South America, CD is emerging throughout the world due to climate change and increased immigratory flux of infected people to non-endemic regions. Containing of the diffusion of CD is challenged by the asymptomatic nature of the disease in early infection stages and by the lack of a rapid and effective diagnostic test.

The value of lamp to rule out imported malaria diagnosis: a retrospective observational study in Milan, Italy.

Background: The diagnosis of malaria in returning travellers could be a challenge in non-endemic settings. We aimed to assess the performance of LAMP in comparison with standard conventional diagnostic methods using real-time-polymerase chain reaction (PCR) in case of discordant results.

Methods: All travellers returning from malaria-endemic areas who presented to our Emergency Department (ED) from January 2017 to December 2020 with signs and symptoms suggestive for malaria were included.

A Lab-On-chip Tool for Rapid, Quantitative, and Stage-selective Diagnosis of Malaria.

Malaria remains the most important mosquito-borne infectious disease worldwide, with 229 million new cases and 409.000 deaths in 2019. The infection is caused by a protozoan parasite which attacks red blood cells by feeding on hemoglobin and transforming it into hemozoin.

Structure, Immunoreactivity, and In Silico Epitope Determination of SmSPI Serpin for Immunodiagnostic Application.

The human parasitic disease Schistosomiasis is caused by the trematode flatworm that infects freshwaters in tropical regions of the world, particularly in Sub-Saharan Africa, South America, and the Far-East. It has also been observed as an emerging disease in Europe, due to increased immigration. In addition to improved therapeutic strategies, it is imperative to develop novel, rapid, and sensitive diagnostic tests that can detect the parasite, allowing timely treatment.

A case of crusted scabies with a delayed diagnosis and inadequate therapy.

Crusted scabies is an infrequent disease caused by Sarcoptes scabiei that usually affects patients with underlying medical conditions leading to immunosuppression. Here, we present the case of an 81 years old man, diagnosed with crusted scabies who came to our attention after multiple misdiagnosis and incorrect and potentially detrimental treatment with steroids. He was admitted to our inpatients ward and treated with oral ivermectin plus local permethrin.

Lyme borreliosis incidence in Lombardy, Italy (2000-2015): Spatiotemporal analysis and environmental risk factors.

Lyme borreliosis cases have been reported from Lombardy in northern Italy, where Ixodes ricinus is the main vector of Borrelia burgdorferi sensu lato. However, spatial and temporal variation in the incidence of Lyme borreliosis is not well understood. In the present study, based on new notified cases of Lyme borreliosis from 2000 to 2015, an average of 1.

A case of Plasmodium malariae recurrence: recrudescence or reinfection?

Background: Plasmodium malariae is the most neglected of the six human malaria species and it is still unknown which is the mechanism underlying the long latency of this Plasmodium.

Case Presentation: A case of PCR-confirmed P. malariae recurrence in a 52-year old Italian man was observed 5 months after a primary attack.

Occurrence of Lyme disease infection in a non-endemic area in Northern Italy.

Background: In Italy, the incidence of human tick-borne disease has increased over the last decades. Since 2015 a multidisciplinary group has been established in Sacco Hospital for the management of the patients affected by Lyme disease (LD). A retrospective evaluation (2015-2017) was performed for LD in non-endemic areas.

Diagnosis of Louse-Borne Relapsing Fever despite Negative Microscopy in Two Asylum Seekers from Eastern Africa.

We report two cases of louse-borne relapsing fever observed at our Institution in June 2016. Both patients were young asylum seekers from Africa who had recently arrived in Milan, Italy. Notably, direct microscopic examination of peripheral blood smears was repeatedly negative for the presence of spirochetes and the diagnosis, supported by clinical and epidemiologic evidence, required molecular confirmation by polymerase chain reaction amplification of DNA extracted from blood and sequencing of the amplified products.

Severe Plasmodium falciparum malaria in the intensive care unit: A 6-year experience in Milano, Italy.

Background: Severe imported Plasmodium falciparum malaria is a potentially life-threatening disease with a reported mortality rate of 5-10% when patients are admitted to the Intensive Care Unit.

Methods: To retrospectively review the clinical aspects, the value of severity predictive scores and the management of patients with severe P. falciparum malaria admitted to an ICU in Milano, Italy between January 2010 and December 2015.

Chagas disease in Europe: A review for the internist in the globalized world.

Chagas disease (CD) or American trypanosomiasis identified in 1909 by Carlos Chagas, has become over the last 40years a global health concern due to the huge migration flows from Latin America to Europe, United States, Canada and Japan. In Europe, most migrants from CD-endemic areas are concentrated in Spain, Italy, France, United Kingdom and Switzerland. Pooled seroprevalence studies conducted in Europe show an overall 4.

Pancreas divisum: correlation between anatomical abnormalities and bile precipitation in the gallbladder in seven patients.

Pancreas divisum is a genetic defect associated with recurrent acute pancreatitis due to insufficient drainage of the accessory pancreatic duct. Seven young patients diagnosed with pancreatic divisum and thickening of the gallbladder bile as shown on magnetic resonance cholangio-pancreatography without pancreatic ductal changes underwent laparoscopic cholecystectomy. During the mean follow-up of 32 months no episode of pancreatitis was reported.

CAND-LO 2014-15 study: changing epidemiology of candidemia in Lombardy (Italy).

Purpose: The aim of this study was to monitor recent changes in the epidemiology of candidemia and in the antifungal susceptibility profiles of Candida isolates in one Italian region (Lombardy) in 2014-2015 in comparison with two other studies performed in the same area in 1997-1999 and in 2009.

Methods: A laboratory-based surveillance was conducted in 11 microbiology laboratories. Identification of Candida isolates from 868 episodes and antifungal susceptibility testing (YeastOne) was performed locally.

Epidemiology of Imported Leishmaniasis in Italy: Implications for a European Endemic Country.

In the past decade, the number of imported leishmaniasis cases has increased in countries of Western Europe. The trend is associated with increasing travels, ecotourism activity, military operations and immigration. While in endemic countries leishmaniasis is usually well diagnosed, accurate patient history and parasite identification are necessary to distinguish between autochthonous and imported cases.

Salinomycin and other ionophores as a new class of antimalarial drugs with transmission-blocking activity.

The drug target profile proposed by the Medicines for Malaria Venture for a malaria elimination/eradication policy focuses on molecules active on both asexual and sexual stages of Plasmodium, thus with both curative and transmission-blocking activities. The aim of the present work was to investigate whether the class of monovalent ionophores, which includes drugs used in veterinary medicine and that were recently proposed as human anticancer agents, meets these requirements. The activity of salinomycin, monensin, and nigericin on Plasmodium falciparum asexual and sexual erythrocytic stages and on the development of the Plasmodium berghei and P.
