Example of antimicrobial stewardship program in a community hospital in Italy.

BACKGROUND: Inappropriate use of antibiotics has caused the emergence of resistant strains of bacteria. The hospital of Alessandria, Italy, implemented an antimicrobial stewardship (AS) pilot program between 2013 and 2015 in the intensive care units (ICUs) and internal medicine departments of Casale Monferrato and Tortona. We aimed to describe the project, results at the end of the intervention, and its strengths and weaknesses. METHODS: The protocol, designed by the local infection control committee, included three consecutive steps: local guidelines for empirical antibiotic therapy and list of prescription antibiotics with justification, monitoring of antibiotic consumption and antimicrobial resistance trend, and peer-to-peer audit sessions in the wards. RESULTS: One thousand and eighty-five observations were made, corresponding to 850 patients admitted to the ICUs (16.7%) and internal medicine departments (83.3%). Appropriate antibiotic prescriptions increased by 6.4% between 2013 and 2015. The greatest improvement in appropriate prescriptions was observed for glycopeptides and fluoroquinolones (+17.4% and +16.2%, respectively). We reported 305 inappropriate prescriptions, with the most frequent errors being absence of an infectious process (33.3%), inadequate combination therapy (12.8%), and absence of microbiological investigations (8.5%). A reduced incidence of methicillin-resistant Staphylococcusaureus (MRSA) was also observed (p<0.0037). CONCLUSIONS: Antimicrobial stewardship programs contribute to improving antibiotic prescription and can be implemented in small community hospitals. Narrower interventions, focused on a single disease or single antibiotic should be encouraged.

Epidemiological evaluation of Leishmania infantum zoonotic transmission risk in the recently established endemic area of Northwestern Italy.

Leishmania infantum infection had been expanding into new areas due to changes in vector and host biology. Zoonotic visceral leishmaniasis has become endemic in previously unsuitable areas as vectors find favourable climatic conditions and an increasing number of reservoir dogs are moved between traditionally and new endemic areas. Monitoring vector and disease expansion in areas of recent colonization is needed to understand transmission mechanisms and patterns of disease establishment. Here, we studied the infection status of 815 human blood donors and of 803 sympatric dogs from five, newly endemic, areas in Northwestern Italy. In autochthonous dogs, the seroprevalence of anti-L. infantum antibodies, recorded by Western blot, reached 42.22%, while in humans, the seroprevalence was of 16.81%. No significant correlation between the infection status of dogs and that of their human owners was found, but L. infantum infection was recorded in the different study areas with significant levels of diversity. Restriction fragment length polymorphism showed a high genetic variability of the circulating strains and gave useful insights on patterns of disease establishment into a naïve area.

Clinical usefulness of ELISPOT assay on pericardial fluid in a case of suspected tuberculous pericarditis.

Rapid and accurate diagnosis of tuberculous pericarditis is often difficult, considering the low specificity of both clinical picture and laboratory tests on pericardial fluid, as well as the low sensitivity of microbiological tests. This report documents the feasibility and clinical usefulness of an Interferon (IFN) - gamma ELISpot - TB assay on pericardial fluid cells in a case of suspected tuberculous pericarditis presenting with tamponade. As large pericardial effusions requiring pericardiocentesis are relatively frequent in tuberculous pericarditis, the physician may consider this particular application of ELISpot-TB as a rapid decision aid for starting the treatment.

Dogs' parasite and zoonotic risk: from old to new "emergencies" in the North-West of Italy.

Toxocariasis due to soil contamination from dog and cat faeces has been long described and represents one of the zoonotic risk linked with pets presence in human settlements. Soil samples were collected from private backyards and school playgrounds in Turin and tested for the presence of Toxocara spp. eggs. Samples from dogs and cats living in the same area were also analysed and our results seem to indicate a decrease in soil contamination respect to a survey carried out in 1985. Considering that recently new foci of Canine Leishmaniosis and the presence of competent sand fly vectors have also been reported in the North-West of Italy, a survey was carried out on dogs and humans living in Asti province. To assess the risk of local Leishmania infantum transmission between dog and humans, samples were also analysed by Restriction Fragment Length Polymorphism (PCR-RFLP). Our results have shown that more than 10% of autochthonous dogs and human being living in this previously non-endemic area have been infected by L. infantum. The identity of PCR-RFLP patterns from 3 human clinical cases and from the dogs of one of them allows us to confirm the autochthonous origin of these cases.

Adrenal location of the echinococcus. Considerations on a clinical case.

Adrenal location of a hydatic cyst is a clinical occurrence of exceptional rarity, especially in its primitive form and it could be evaluated, on the operative and autoptic comparison, not to exceed overall 0.5% of all the possible locations. Moreover, among all the cystic formations of the adrenal glands, parasitic ones are only 7%. Our observation of a case of adrenal hydatidosis, initially suspected as hepatic mass, was casually discovered by means of abdominal ultrasonography and later confirmed with the operation. This work contributes to the knowledge of this pathology, emphasizing diagnostic difficulties, and, considering the exiguous literature, helping us in supplying real indications to the surgical treatment.

Social support as road map and vehicle: an analysis of data from focus group interviews with a group of African American women.

As part of a larger study of the impact of a social support intervention on pregnancy outcome for lower-income African American women, 6 African American women (a medical social worker, a physician's assistant, 2 community outreach workers, a lactation consultant, and a health project representative) participated in focus group discussions concerning the unique social support needs of lower-income African American women during pregnancy. Transcripts of focus group interviews were analyzed using qualitative content analysis. Emergent themes included strengths of African American communities, deficiencies in social support for many lower-income African American women, the meaning of pregnancy for African American women, the ability of many pregnant women to "make it" without visible means of support, young women's locations "inside" and "outside" of "mainstream" life, and the importance of social support as a mechanism for guiding and transporting "lost souls" back into the mainstream.

[Extrahepatic gastrinoma. Report of a clinical case]. / Gastrinoma extrapancreatico. Descrizione di un caso clinico.

Gastrinoma is a rare neoplasia producing gastrina, the hormone responsible of the clinic manifestations related to Zollinger-Ellison syndrome. The localization of gastrinoma is pancreatic or extrapancreatic (usually in Stabile and Passaro triangle). We present a case report concerning an extra-pancreatic gastrinoma not localized in this area and included in a lymph node. This is an extremely infrequent localization (2.4%). There are two different opinions about this localization. Some authors think that this is always a secondary lesion of a small primary neoplasia usually asymptomatic. Other authors think that there are primary lymph nodal gastrinomas that could be safely removed with excision of lymph node. The infrequent localisation of this case induced us to report this experience in order to contribute to the comprehension of this pathology.
