Fecal shedding of thermophilic Campylobacter in a dairy herd producing raw milk for direct human consumption.

Factors affecting the thermophilic Campylobacter fecal shedding in Italian dairy farming conditions have been investigated in a 12-month longitudinal study performed in a dairy farm authorized to sell raw milk in Italy. Fifty animals were randomly selected from 140 adult and young animals, and fecal sampling was performed six times at two month intervals; additionally at each sampling, three trough water samples and two trough feed samples were collected for both adult and young animals. Samples were analyzed by real-time PCR and cultural examination. Overall 33 samples (9.7%) were positive for thermophilic Campylobacter by real-time PCR: 26 out of 280 (9.2%) fecal samples, six out of 36 water points (16.6%) and one of the 24 feed samples (4.2%). Campylobacter jejuni was isolated from 6 out of 280 samples; no other Campylobacter sp. was isolated. A higher but not significant positivity was observed in fecal samples of younger animals (11.33%% versus 6.92% of adult animals) and a higher and significant positivity was observed in water samples collected from the water troughs of young animals. A distinct temporal dynamic trend was observed during the study period for both cows and calves, with two prevalence peaks between November/December and between May/July. Several factors such as calving, housing practices, herd size, management practices forcing together a higher number of animals, variations in feeding or water source, which were previously reported as cause of temporal variation in different farming conditions, could be excluded as cause of the two seasonal peaks in this study. The factors affecting the seasonality of Campylobacter shedding in the dairy herds remain unclear and warrant further investigation. The results of the present study indicate that special attention should be paid to farm hygiene management in farms authorized to produce and sell raw milk with increased surveillance by the authorities in certain periods of the year

Emergenza sismica nel centro Italia 2016-2017. Secondo rapporto del gruppo operativo SISMIKO. Sviluppo e mantenimento della rete sismica mobile a seguito del terremoto di Amatrice Mw 6.0 (24 agosto 2016, Italia centrale)

La rete sismica temporanea installata dal gruppo operativo INGV SISMIKO a seguito del terremoto del 24 agosto 2016 tra i Monti della Laga e la Valnerina, è stata ampliata nel settore settentrionale a seguito dei forti terremoti avvenuti alla fine del mese di ottobre 2016. Successivamente alle due scosse di Mw 5.4 e 5.9 che il 26 ottobre hanno interessato l’area al confine Marche-Umbria tra i Comuni di Castelsantangelo sul Nera (MC), Norcia (PG) e Arquata del Tronto (AP), la geometria della rete è stata estesa di circa 25 km verso nord con l’attivazione di ulteriori tre stazioni temporanee di cui una, da subito, disposta per la trasmissione dei dati in tempo reale e per l’inserimento nel sistema di sorveglianza sismica dell’Istituto Nazionale di Geofisica e Vulcanologia (INGV). Un’ultima stazione è stata inoltre installata nei pressi di Campello del Clitunno in provincia di Perugia ad ovest della sequenza, a seguito del terremoto Mw 6.5 che la mattina del 30 ottobre ha interessato l’intera area già fortemente provata dalla sequenza in corso; questo è stato il più forte terremoto registrato negli ultimi 30 in Italia. A circa 5 mesi dall’inizio dell’emergenza sismica, la rete temporanea conta quindi 23 stazioni che da metà dicembre sono tutte trasmesse in tempo reale ai diversi centri di acquisizione INGV, ovvero Milano, Ancona e Grottaminarda ma soprattutto Roma dove i dati vengono contestualmente archiviati nell’European Integrated Data Archive (EIDA) e integrati nel sistema di monitoraggio e sorveglianza sismica dell’INGV; per la sorveglianza sono incluse solo parte delle stazioni. Nelle ultime settimane, le attività di campagna del gruppo operativo SISMIKO sono state costantemente focalizzate alla cura e alla manutenzione della strumentazione per garantire la continuità della trasmissione e dell’acquisizione dei dati, a volte compromesse da malfunzionamenti legati al maltempo. Alla data di aggiornamento del presente report, non è ancora stata decretata una dismissione o una rimodulazione della geometria della rete sismica temporanea, anche in considerazione della attività sismica in corso a tutt’oggi molto sostenuta. Tutti i dati acquisiti dalle stazioni temporanee SISMIKO, sono distribuiti senza alcun vincolo, al pari dei dati della Rete Sismica Nazionale (RSN, codice di rete IV), ed utilizzati per prodotti scientifici in tempo reale (localizzazioni di sala, calcolo dei Time Domain Moment Tensor -TDMT delle ShakeMaps, ecc) e per l’aggiornamento dei database dell’INGV come l’Italian Seismological Instrumental and Parametric Database (ISIDe) con la revisione del Bollettino Sismico Italiano (BSI), dell’INGV Strong Motion Data (ISMD) e dell’ITalian ACcelerometric Archive (ITACA), dell’European-Mediterranean Regional Centroid Moment Tensors (RCMT) e nei lavori scientifici che utilizzano forme d’onda velocimetriche ed accelerometriche (ri- localizzazioni, studi della sorgente sismica ecc.).Istituto Nazionale di Geofisica e Vulcanologia (INGV)Published1SR.

SISMIKO:emergency network deployment and data sharing for the 2016 central Italy seismic sequence

At 01:36 UTC (03:36 local time) on August 24th 2016, an earthquake Mw 6.0 struck an extensive sector of the central Apennines (coordinates: latitude 42.70° N, longitude 13.23° E, 8.0 km depth). The earthquake caused about 300 casualties and severe damage to the historical buildings and economic activity in an area located near the borders of the Umbria, Lazio, Abruzzo and Marche regions. The Istituto Nazionale di Geofisica e Vulcanologia (INGV) located in few minutes the hypocenter near Accumoli, a small town in the province of Rieti. In the hours after the quake, dozens of events were recorded by the National Seismic Network (Rete Sismica Nazionale, RSN) of the INGV, many of which had a ML > 3.0. The density and coverage of the RSN in the epicentral area meant the epicenter and magnitude of the main event and subsequent shocks that followed it in the early hours of the seismic sequence were well constrained. However, in order to better constrain the localizations of the aftershock hypocenters, especially the depths, a denser seismic monitoring network was needed. Just after the mainshock, SISMIKO, the coordinating body of the emergency seismic network at INGV, was activated in order to install a temporary seismic network integrated with the existing permanent network in the epicentral area. From August the 24th to the 30th, SISMIKO deployed eighteen seismic stations, generally six components (equipped with both velocimeter and accelerometer), with thirteen of the seismic station transmitting in real-time to the INGV seismic monitoring room in Rome. The design and geometry of the temporary network was decided in consolation with other groups who were deploying seismic stations in the region, namely EMERSITO (a group studying site-effects), and the emergency Italian strong motion network (RAN) managed by the National Civil Protection Department (DPC). Further 25 BB temporary seismic stations were deployed by colleagues of the British Geological Survey (BGS) and the School of Geosciences, University of Edinburgh in collaboration with INGV. All data acquired from SISMIKO stations, are quickly available at the European Integrated Data Archive (EIDA). The data acquired by the SISMIKO stations were included in the preliminary analysis that was performed by the Bollettino Sismico Italiano (BSI), the Centro Nazionale Terremoti (CNT) staff working in Ancona, and the INGV-MI, described below

The use of the Alexis(®) device in breast augmentation to improve outcomes. A comparative randomized case-control survey.

Background: We present our experience in using a disposable wound retractor commonly used in abdominal surgery named Alexis® (Applied Medical Resources Corporation, Rancho Santa Margarita, CA, USA), during breast augmentation in order to improve outcomes, particularly final scar length. Methods: Between January 2010 and November 2012, 40 patients undergoing breast augmentation with an inframammary approach were enrolled in the present study. Patients were randomly assigned to two groups: group 1 underwent breast augmentation with the standard technique; group 2 underwent breast augmentation by using the Alexis® (Applied Medical Resources Corporation) device. Patients were followedup for a 12-month period. The time of surgery, the days of drain duration and the length of the incisions were recorded for both groups and statistical significance was evaluated with the Wilcoxon rank sum test. Also, final scar appearance was evaluated using a visual analogue scale (VAS). Results: Patients in group 2 reported a lower incidence of hematomas and had shorter drain duration. The difference in scar length between the two groups was statistically significant (P<0.05). Surgeons and patients were mostly satisfied with the final appearance of the scar. Conclusions: The use of the Alexis® (Applied Medical Resources Corporation) device has proven useful in reducing the length of the inframammary incision. Interestingly, the increased visibility obtained with the use of the Alexis device allowed a better hemostasis, as suggested by the shorter drain duration and lower incidence of hematomas. However, its use prolongs the operative time, for which we recommend surgeons to allow themselves some time to become familiar with the device. Level of evidence: level I, evidence obtained from at least one properly designed randomized controlled trial

Occurrence of Vibrio parahaemolyticus, Vibrio cholerae and Vibrio vulnificus in the clam Ruditapes Philippinarum (Adams & Reeve, 1850) from Emilia Romagna and Sardinia, Italy

Marine vibrios, Vibrio parahaemolyticus, V. vulnificus and V. cholerae are responsible of the majority of food-borne human infections by consumption of bivalve shellfish. The aim of the present study was to ascertain the occurrence of these bacteria, and their potential pathogenicity, in the Manila clam R. philippinarum from Emilia Romagna (ER) and Sardinia (SR) regions, Italy. Isolation was performed on CHROMagar\u2122 vibrio with subculture on (thiosulfate-citrate-bile salts-sucrose) Agar and m-modified-cellobiose-polymyxin bcolistin (-CPC) Agar. Suspected strains were purified, biochemically characterized and genotyped by simplex polymerase chain reaction (PCR) for the specie-specific and pathogenic gene markers: V. parahaemolyticus (toxRP, tdh and trh); V. vulnificus (vvhA, hsp, vcgC, vcgE, CPS operon allele 1, CPS operon allele 2, 16s-rRNA operon allele A, 16s-rRNA operon allele B; V. cholerae (toxRC, hlya, tcpI, tcpA, ctxA, ctxB, stn/sto). Moreover a multiplex PCR was applied to the SR bivalve shellfish, for the simultaneous detection of the three targets directly on homogenate samples, targeting the species-specific gene for V. cholerae (toxRC), V. parahaemolyticus (toxRP) and V. vulnificus (vvhA). As a result of phenotyping and genotyping of isolates, bivalve shellfish from ER resulted positive for V. parahaemolyticus (27.8%) and V. vulnificus (10.1%), but negative for V. cholerae. Shellfish from SR resulted positive for V. parahaemolyticus (30.3%), V. vulnificus (6.1%) and V. cholerae (3%). No significant differences emerged between the two areas (P>0.05)

Retention of polyurethane foam fragments during VAC therapy: A complication to be considered

VAC-therapy is a closed-loop, non-invasive active system, characterised by a controlled and localized negative pressure applied on porous polyurethane absorbent foams. It promotes healing of acute and chronic wounds. Therapeutic effects of VAC-therapy have been proved and demonstrated, however this method can have some disadvantages. Even if it is a quite versatile device, only qualified medical/paramedical personnel should use it in order to avoid possible complications that can occur after an improper application. In this report, 11 cases of foam fragment retention within the wound are presented. This rare complication did not promote healing, but further hindered it. On the basis of our experience, it is mandatory to define indications, benefits and limitations of the VAC-therapy
