Poliovirus and Other Enteroviruses from Environmental Surveillance in Italy, 2009-2015.

Within the initiatives for poliomyelitis eradication by WHO, Italy activated an environmental surveillance (ES) in 2005. ES complements clinical Acute Flaccid Paralysis (AFP) surveillance for possible polio cases, detects poliovirus circulation in environmental sewage, and is used to monitor transmission in communities. In addition to polioviruses, the analyses comprised: (i) the monitoring of the presence of non-polio enteroviruses in sewage samples and (ii) the temporal and geographical distribution of the detected viruses.

Tick-borne encephalitis in north-east Italy: a 14-year retrospective study, January 2000 to December 2013.

Italy is considered at low incidence of tick-borne encephalitis (TBE), and the occurrence of human cases of TBE appears to be geographically restricted to the north east of the country. However, most information to date derives from case series, with no systematic data collection. To estimate incidence rates (IR) and spatial distribution of TBE cases, we conducted a retrospective study in north-eastern Italy.

Human seroprevalence against Borrelia burgdorferi sensu lato in two comparable regions of the eastern Alps is not correlated to vector infection rates.

Seroprevalences were determined by testing sera of 1607 blood donors from North, East, and South Tyrol. In the Tyrols, the continental divide delimitates areas with high seroprevalences of IgG antibodies against Borrelia burgdorferi sensu lato in the North (7.2%) from areas with low seroprevalences in the South (1.

Investigations on California serogroup orthobunyaviruses in the Tyrols: first description of Tahyna virus in the Alps.

Seroprevalence rates for immunoglobulin G (IgG) antibodies to Tahyna virus (TAHV) and Inkoo virus (INKV) were determined in sera of 1630 blood donors from North, East, and South Tyrol by immunofluorescence assays (IFAs) and confirmatory serum neutralization tests (SNTs). Ten sera (0.6%) reacted positive by TAHV IFA, five of which (0.

Risk assessment of transfusion-associated babesiosis in Tyrol: appraisal by seroepidemiology and polymerase chain reaction.

Background: After malaria, babesiosis is the second most common transfusion-transmitted parasitic disease in the United States. In Europe, one reported transfusion case, concerning Babesia microti, occurred in Germany.

Study Design And Methods: Due to the fact that Babesia spp.

Detection of Enteroviruses in Influent and Effluent Flow Samples from Wastewater Treatment Plants in Italy.

This study evaluated the presence and seasonal distribution of polio and other enteroviruses in four wastewater treatment plants in three cities in Italy, using different treatment systems. Detection of enteroviruses was carried out by virus isolation in cell cultures after concentration of water samples collected at both inlet and outlet of the treatment plants, following the methods described in the WHO guidelines. Viral serotypes isolated before and after water treatment were compared.

Spotted fever group--Rickettsiae in the Tyrols: evidence by seroepidemiology and PCR.

The aim of our study was to assess the occurrence of Rickettsia in the inner-alpine valleys of the Eastern Alps and to determine the amount of seroreaction among the local human population. Ticks were investigated by PCR and the percentage of seropositives was determined among local blood donors by an in-house immunofluorescence assay. The local cut-off titre for screening of IgG was set at 1 : 128 with a well-characterised low-risk collective according to WHO-guidelines.

Absence of indigenous specific West Nile virus antibodies in Tyrolean blood donors.

In the last several years, West Nile virus (WNV) was proven to be present especially in the neighboring countries of Austria, such as Italy, Hungary, and the Czech Republic, as well as in eastern parts of Austria, where it was detected in migratory and domestic birds. In summer 2010, infections with WNV were reported from Romania and northern Greece with about 150 diseased and increasingly fatal cases. We tested the sera of 1,607 blood donors from North Tyrol (Austria) and South Tyrol (Italy) for antibodies against WNV by using IgG enzyme-linked immunosorbent assay (ELISA).

[The role of the public health personnel in the Prevention Department (in the Hygiene Services and Public Health Care and Hygiene of Food and Nutrition): proposal for the future of public health care].

A global and local discussion on Public Health relevance is taking place, including the future role and organization of its services. Noteworthy becomes the role played by Public Health Specialists. This work presents the results of a workshop, carried out following the Guilbert methodology, whose aim was to define Public Health Doctors functions and their related activities.

ISR II study: a long-term evaluation of sirolimus-eluting stent in the treatment of patients with in-stent restenotic native coronary artery lesions.

The aim of this pilot study was to determine the safety and long-term efficacy of treating intrastent restenosis (ISR) with the slow-release sirolimus-eluting stent Bx Velocity (Cypher stent) without intravascular ultrasound (IVUS) guidance. Of patients who received a bare metal stent implantation and presented an ISR, 30-80% of the patients will develop a second restenosis within the stent, at the stent edges or both. To date, intravascular brachytherapy using beta- and gamma-radiation has been the only effective treatment for ISR.

An experimental model of gastroschisis using fetoendoscopy: preliminary results and technical considerations.

Background: The aim of this study was to show the feasibility of an experimental model of gastroschisis using fetoendoscopic surgery on sheep fetuses, and also to perform amnioinfusion until delivery using an in-dwelling intraamniotic catheter.

Methods: We analyzed the data from 18 pregnant ewes having 26 fetuses, which underwent surgery at 80 days of gestation (full term, 145 days). The fetendo technique was used to create a gastroschisis in 15 fetuses.

Costal cartilage grafting for repair of a recurrent tracheoesophageal fistula in a 1.6-kg baby with esophageal atresia.

A large intraoperative tracheal tear occurred during correction of a type III esophageal atresia in a 1,630-g premature baby. It was repaired by primary suture. Recurrence of the tracheoesophageal fistula (TEF) was treated operatively with esophageal exclusion and costal cartilage grafting (CCG) onto the tracheal defect.

Prevalence of antibodies to Leptospira serovars in sheep and goats in Alto Adige-South Tyrol.

Serum samples from 313 sheep and 95 goats were collected during November 1993 in 26 localities in Alto Adige-South Tyrol and tested by microscopic agglutination test for antibodies to 28 serovars of the genus Leptospira. At the time of blood collection all the animals appeared healthy with no clinical sign suggestive of leptospirosis. The observed seroprevalence in sheep was 6.

Unprotected left main coronary artery stenting: immediate and medium-term outcomes of 140 elective procedures.

Objectives: We sought to evaluate immediate and late outcomes after stenting for left main coronary artery (LMCA) stenosis.

Background: Conventional percutaneous transluminal coronary angioplasty (PTCA), for which coronary artery bypass grafting (CABG) has been the gold standard therapy for years, has yielded poor results in unprotected LMCA lesions. The development of coronary stents, together with their dramatic patency improvement provided by new antiplatelet regimens and their validation against restenosis, warrants a reappraisal of angioplasty in LMCA stenosis.

Clinical experience with a new biocompatible phosphorylcholine-coated coronary stent.

Aims: The BiodivYsio stent is a new stent coated with phosphorylcholine, a biocompatible molecule designed to reduce the formation of thrombus and potentially the risk of restenosis. The feasibility, safety, and efficacy of elective and urgent implantation of this coated coronary stent were prospectively studied.

Methods And Results: We studied 224 patients who underwent elective (67%) or bail-out implantation of 303 BiodivYsio stents in 286 lesions.

[Contralateral transinguinal laparoscopy in unilateral inguinal hernia].

Background: Indication for surgical exploration of the contralateral groin during unilateral herniorraphy in children is the subject of a worldwide debate. Routine exploration based on the likelihood of a patent processus vaginalis (PV) according to age, gender or side to some extent leads to unnecessary procedures, while routine abstention may leave a peritoneal sac, likely to later induce a symptomatic hernia in about 10% of cases.

Methods And Patients: One hundred and twenty-five children aged from 1 month to 15 years underwent transinguinal laparoscopic assessment of the contralateral groin, using a 3 mm trocar and a 70 degrees telescope gently introduced through the exposed PV.

Antigenic and genomic analysis of a Borrelia burgdorferi sensu stricto strain isolated from Ixodes ricinus ticks in Alto Adige-South Tyrol, Italy.

A Borrelia burgdorferi sensu lato strain isolated from IXodes ricinus ticks in Alto Adige-South Tyrol (Northern Italy) was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of whole cell proteins, Western immunoblotting analysis (WBA) with polyclonal and monoclonal antibodies, and pulsed-field gel electrophoresis (PFGE). The isolate named BZ6 was identified as belonging to the genospecies B. burgdorferi sensu stricto on the basis of its protein profile and its reactivity with monoclonal and polyclonal antibodies.

Surgical approach of an early mammalian embryo: the rabbit model.

We describe an experimental surgical model in early rabbit embryo (12.5 days of gestation). Twenty-one embryos were operated, of which 9 survived the first postoperative week and 5 had normal further growth until term.

Coronary artery stenting without anticoagulation, aspirin, ultrasound guidance, or high balloon pressure: prospective study of 1,051 consecutive patients.

Between March 1994 and November 1995, 1,212 coronary stents were implanted in 1,051 consecutive patients at our institution with the following protocol: daily pre- and poststenting treatment with ticlopidine 500 mg without aspirin, implantation under angiographic guidance, without ultrasound, with semi-compliant balloons inflated at 10 bars. Stenting was indicated after failure of balloon angioplasty (bail-out, dissection, elastic recoil) in 27% of the patients and considered as elective (de novo, restenosis, chronic occlusion, saphenous vein grafts) in 73% of the cases. During the 30-day follow-up period, stent thrombosis occurred in 11 patients (1.

[Surgical approach on rabbit embryos. A model trial of bladder exstrophy].

We describe herein a new model of surgical approach of an early mammalian embryo. Indeed the developmental mechanisms of numerous congenital anomalies, such as bladder exstrophy, remain obscure, and progresses in their knowledge must be achieved to propose better treatments. But up to now all the successful reports in experimental models of early produced malformations concerned birds or batracians, whose development is very different from human.

Artificial urinary sphincter implantation for neurogenic bladder: a multi-institutional study in 107 children.

Objectives: To evaluate the outcome of implantation of the AMS 800 artificial urinary sphincter in children with neurogenic bladder.

Patients And Methods: The records of 107 children (74 boys and 33 girls) treated for neurogenic urinary incontinence by implantation of the AMS 800 artificial sphincter between 1983 and 1993 were reviewed retrospectively. The underlying cause of incontinence in 92 patients was spina bifida, the mean age at implantation was 13.

Antibodies to Borrelia burgdorferi in sheep and goats. Alto Adige-South Tyrol, Italy.

A serologic survey for antibodies to Borrelia burgdorferi was conducted on sheep and goat serum samples collected in Alto Adige-South Tyrol, Italy, in 1990. Sera were tested by Indirect Immune Fluorescence Assay (IIFA) and Microbial Adherence Immobilization Assay (MAIA). IIFA and/or MAIA anti-B.

Heterozygous endothelin receptor B (EDNRB) mutations in isolated Hirschsprung disease.

Hirschsprung disease (HSCR, aganglionic megacolon) is a frequent congenital malformation regarded as a multigenic neurocristopathy. Two susceptibility genes have been recently identified in HSCR, namely the RET proto-oncogene and the endothelin B receptor (EDNRB) gene. Hitherto however, homozygosity for EDNRB mutations accounted for the HSCR-Waardenburg syndrome (WS) association.
