Abstract
A systematic and narrative literature review was performed, focusing attention on the anatomy of the area located at the junction of the sphenoid and the basal portion of the temporal bone (petrous bone, petrous apex, upper petro-clival region) encircled by the free edge of the tentorium, the insertion of the tentorium itself to the petrous apex and the anterior and posterior clinoid processes that give rise to three distinct dural folds or ligaments: the anterior petroclinoid ligament, the posterior petroclinoid ligament and the interclinoid ligament. These dural folds constitute the posterior portion of the roof of the cavernous sinus denominated "the oculomotor triangle". The main purpose of this review study was to describe this anatomical region, particularly in the light of the relationships between the anterior margin of the free edge of the tentorium and the above-mentioned components of the sphenoid and petrous bone.

Abstract
BACKGROUND Pregnant women with neuromuscular diseases (NMDs) often display respiratory muscle impairment which increases the risk for pulmonary complications (PCs). The aim of this study was to identify pregnant NMDs patients with pulmonary risk factors and to apply in these women non-invasive ventilation (NIV) combined with mechanical insufflation-exsufflation (MI-E) in the peri-partum period. METHODS We conducted a multicenter observational study on women with NMDs undergoing cesarean section or spontaneous labor in a network of 7 national hospitals. In these subjects we applied a protocol for screening and preventing PCs, and we evaluated PCs rate, maternal and neonatal outcome. RESULTS Twenty-four patients out of the 94 enrolled pregnant women were at risk for PCs and were trained or retrained to use NIV and/or MI-E before delivery. After delivery, 17 patients required NIV with or without MI-E. Despite nine out of the 24 women at pulmonary risk developed postpartum PCs, none of them needed reintubation nor tracheostomy. In addition, the average birth weight and Apgar score were normal. Only one patient without pulmonary risk factors developed postpartum PCs. CONCLUSION This study showed the feasibility of applying a protocol for screening and treating pregnant NMDs women with pulmonary risk. Despite a PCs rate of 37% was observed in these patients, maternal and neonatal outcome were favorable.

Abstract
Tuberculum sellae meningiomas (TSM) are challenging tumors due to their proximity to vital neurovascular structures. We propose a new classification system based on anatomical and radiological parameters. All patients treated for TSM, between January 2003 and December 2016, have been retrospectively reviewed. A systematic research was performed in PubMed database to review all studies comparing the performance of transcranial (TCA) and transphenoidal (ETSA) approaches. Overall, 65 patients were included in the surgical series. Gross total removal (GTR) was achieved in 55 patients (85%) and near total resection in 10 (15%). 54 patients (83%) showed a stability or an improvement of visual functions and 11 (17%) worsened. Postoperative complications were observed in seven patients (11%): CSF leak in one patient (1.5%); diabetes insipidus in two (3%); hypopituitarism in two (3%) third cranial nerve paresis and subdural empyema in one (1.5%). For the literature review, data about 10,833 patients (TCA N.=9159; ETSA N.=1674) were recorded; GTR was achieved in 84.1% (range 68-92%) of TCA and in 79.1% (range 60-92%) of ETSA; visual improvement (VI) occurred in 59.3% of TCA (range 25-84%) and in 79.3% of ETSA (range 46-100%); visual deterioration (VD) was registered in 12.7% of TCA (0-24%) and in 4.1% of ETSA (range 0-17%); a CSF-leak was observed in 3.8% of TCA (range 0-8%) while in ETSA in 18.6% of patients (range 0-62%); vascular injuries was reported in 4% (range 0-15%) of TCA and in 1.5% (range 0-5%) of ETSA. In conclusion, TSMs represent a unique category of midline tumors. The proposed classification system provides an intuitive and reproducible method in the choice of the most suitable approach.

Abstract
Abstract
Background
The compression of peritumoral healthy tissue in brain tumor patients is considered a major cause of life-threatening neurologic symptoms. This condition is associated with an increase in intracranial pressure. The literature reports that GBM has a mass effect in 72% of autoptic brains of patients who died of brain tumor, with herniation in 50% of all cases.
Material and methods
We present a preliminary clinical series on 5 cases. The patients are chosen based on criteria of recurrent glioblastoma without the possibility of a gross total resection with a recurrence after STUPP protocol. The surgeries include cytoreduction and augmentative craniotomy. The aim is to increase the intracranial volume and reduce the intracranial pressure in evolving glioblastoma. Clinical and radiological follow-up considers different objective scales and contrast enhancement MRI performed every 3 months. We evaluate KPS, survival rate, complication rate, quality of life using QOL-BN20 and neuropsychological assessment.
Results
The 12 months of follow-up shows a mean survival rate of 9 months after the surgery. This procedure has no negative impact on the survival rate, complication rate, and quality of life reduction. The neuropsychological evaluation does not show an impact on self-perception of aesthetic appearance. The surgery does not show surgical wound complications. The mean operative time was 225 minutes and was comparable with standard recurrence glioblastoma procedure.
Conclusion
This work has the main limitation of being preliminary results on small population. However, these results show encouraging outcomes and could be an innovative and salvage therapy for recurrent and incurable glioblastoma. Further follow-up and study must be performed.

Abstract
The honey bee has long been known to be a bioindicator of environmental pollution and the use of antimicrobials in the beekeeping industry is strictly regulated. For these reasons, this paper was aimed to evaluate for the first time the role of Apis mellifera as a possible indicator of environmental antimicrobial resistance (AMR). The study isolated and analysed the resistance patterns of Enterobacteriaceae from a pool of honey bee guts located in five different environmental sites (ES), where different antimicrobial selective pressures were hypothesized. In all, 48 isolates were considered for identification and underwent analyses of AMR to ampicillin, amoxicillin/clavulanic acid, cefazolin, ceftazidime, tetracycline, imipenem, enrofloxacin, amikacin and trimethoprim/sulfamethoxazole. In all, 12 isolates out of 48 (25%) showed resistance to at least one antimicrobial drug. There were no significant differences between the resistance rates observed in the ESs, even if the highest percentage of resistance was found in ES4. Resistances to amoxicillin/clavulanic acid resulted significantly higher than those detected towards the other antimicrobials. Amoxicillin/clavulanic acid is not commonly used in beekeeping but it is extensively used in animals and in humans, suggesting an environmental origin of this resistance and supporting the hypothesis that honey bees could be used as indicators of AMR spread in the environment. SIGNIFICANCE AND IMPACT OF THE STUDY: In this study, a possible role of honey bees as indicator of environmental antimicrobial resistance is hypothesized. Enterobacteriaceae were isolated from bees living in different environmental sites (ES) where different antimicrobial selective pressures were hypothesized. Even if no differences between the resistances in the five ES were observed, the resistance rates for amoxicillin/clavulanic acid, compared to other antimicrobials, were significantly higher. Since amoxicillin/clavulanic acid is not used in beekeeping but it is extensively used in animals and in humans, an environmental origin of this resistance is suggested that supports our hypothesis.

Abstract
This paper describes for the first time the isolation of Streptococcus lutetiensis in a cat with intestinal lymphoma. The Streptococcus bovis group has undergone significant taxonomic changes over the past two decades and, in 2002, Poyart et al. described two distinct novel species within the genus Streptococcus: Streptococcus lutetiensis and Streptococcus pasteurianus. The bovis group streptococci include commensal species and subspecies or opportunistic pathogens of humans and animals. The cat was referred to the Veterinary Teaching Hospital, University of Bologna for chronic diarrhoea associated with fresh blood. A diagnosis of intestinal lymphoma was advanced. S. lutetiensis was accidentally isolated from the faeces of the cat and identified through MALDI-TOF and 16s rRNA sequencing. The Kirby-Bauer test revealed that the isolate was resistant to enrofloxacin, erythromycin, clindamycin, marbofloxacin and tetracycline. The detection of S. lutetiensis in cat faeces might suggest that it could be a normal inhabitant of cat intestinal tract or that it could be involved in the manifestation of intestinal diseases. Since bacteria belonging to the S. bovis group are considered emerging pathogens, additional research is required to evaluate the role of S. lutetiensis in cats and its role in the transmission of antimicrobial resistance. SIGNIFICANCE AND IMPACT OF THE STUDY: In this study the isolation of Streptococcus lutetiensis from a cat with intestinal lymphoma was described for the first time. An antimicrobial susceptibility test performed by means of the disc diffusion method revealed that the isolate was resistant to enrofloxacin, erythromycin, clindamycin, marbofloxacin and tetracycline. Nowadays the ecological or pathogenetic role of S. lutetiensis in the gut of animals remains unclear but, even if its role as commensal bacterium was confirmed, the presence of multi-resistant S. lutetiensis in cat gut could favour the transmission of antimicrobial resistance to other bacteria.

Abstract
Fresh vegetables and their ready-to-eat (RTE) salads have become increasingly recognized as potential vehicles for foodborne diseases. The EU Reg. 1441/2007 establishes microbiological criteria for bacterial pathogens for products placed on the market during their shelf-life (i.e. Salmonella spp., Listeria monocytogenes) for pre-cut fruits and vegetables (RTE) whilst it does not address the problem of contamination by enteric viruses. In this study we investigated the contamination by hepatitis A virus (HAV), hepatitis E virus (HEV) and norovirus (NoV) in 911 ready-to-eat vegetable samples taken from products at retail in Apulia and in Lombardia. The vegetable samples were tested using validated real-time PCR (RT-qPCR) assays, ISO standardized virological methods and ISO culturing methods for bacteriological analysis. The total prevalence of HAV and HEV was 1.9% (18/911) and 0.6% (6/911), respectively. None of the samples analysed in this study was positive for NoV, Salmonella spp. or Listeria monocytogenes. The detection of HAV and HEV in RTE salads highlights a risk to consumers and the need to improve production hygiene. Appropriate implementation of hygiene procedures is required at all the steps of the RTE vegetable production chain and this should include monitoring of emerging viral pathogens.

Abstract
Chondromyxoid fibroma (CMF) is an extremely rare lesion of the skull base. This histologic type typically predilects metaphysis of the long bones. It is locally invasive/infiltrative, and this tendency is more concerning in the skull base, where a radical resection is often technically impossible because of the presence of vital neurovascular structures. We present a case of a 19-year-old woman who presented with a sudden onset of right facial weakness, progressively worsening to a severe disfiguring motor weakness. Gadolinium-enhanced brain magnetic resonance imaging showed an osteolytic lesion located in the right mastoid involving the stylomastoid foramen and the right seventh cranial nerve. A partial mastoidectomy was performed, with an excellent rate of tumor resection and complete local control of the disease at follow-up. The analysis of current literature indicates that a radiologic diagnosis is rarely strictly convincing of CMF. Histologic diagnosis is often difficult due to the lack of a specific immunohistochemical pattern of chondrosarcoma. Surgery is currently recognized as the mainstay to manage this lesion, although a trend toward adjuvant radiation therapy (RT) currently is seen. Although a tendency of local recurrence is well recognized in the literature, the very slow and indolent behavior of this lesion plus the trend to enhance local control of the disease with high-dose RT pushed us to a reappraise the role of radical skull base surgeries burdened by the risks of major complications, cosmetic deformities, and additional neurologic deficits.

AIMS This comparative study investigated the occurrence of cadF, cj1349, ciaB, pldA, tlyA, hecA, hecB, mviN, irgA and IroE genes in 212 Arcobacter butzleri isolated from three different environmental sites linked to the dairy chain (farms, industrial and artisanal dairy plants) located in three Italian regions (Lombardy, Emilia-Romagna and Calabria). METHODS AND RESULTS According to the presence of these genes, different pathotypes (P-types) were determined. The main genes detected were ciaB, mviN, tlyA, cj1349, pldA and cadF, while the least common genes were iroE, hecA, hecB and irgA. TlyA, irgA, hecA, hecB and iroE, which were significantly more frequent in isolates recovered in industrial dairy plants. Twelve P-types were detected. The occurrence of the most frequently detected P-types (P-types 1, 2, 3 and 5) differed significantly (P < 0·001) in relation to both the environmental site and geographical area of isolation. The highest diversity in P-types was observed in industrial dairy plants and in the Calabria region. CONCLUSIONS The results of this study show a correlation between the occurrence of putative virulence genes and virulence genotype variability depending on the environmental site and geographical origin of the isolates. SIGNIFICANCE AND IMPACT OF THE STUDY The present study provides insights into the similar distribution of putative virulence genes in a dairy chain and other sources' isolates and also into a geographical distribution of some P-types. We have shown that industrial dairy plants may represent an environmental site favouring a selection of the isolates with a higher pathogenetic pattern.

Abstract
A quantitative risk assessment (RA) was developed to estimate haemolytic-uremic syndrome (HUS) cases in paediatric population associated with the consumption of raw milk sold in vending machines in Italy. The historical national evolution of raw milk consumption phenomenon since 2008, when consumer interest started to grow, and after 7 years of marketing adjustment, is outlined. Exposure assessment was based on the official Shiga toxin-producing Escherichia coli O157:H7 (STEC) microbiological records of raw milk samples from vending machines monitored by the regional Veterinary Authorities from 2008 to 2014, microbial growth during storage, consumption frequency of raw milk, serving size, consumption preference and age of consumers. The differential risk considered milk handled under regulation conditions (4°C throughout all phases) and the worst time-temperature field handling conditions detected. In case of boiling milk before consumption, we assumed that the risk of HUS is fixed at zero. The model estimates clearly show that the public health significance of HUS cases due to raw milk STEC contamination depends on the current variability surrounding the risk profile of the food and the consumer behaviour has more impact than milk storage scenario. The estimated HUS cases predicted by our model are roughly in line with the effective STEC O157-associated HUS cases notified in Italy only when the proportion of consumers not boiling milk before consumption is assumed to be 1%. Raw milk consumption remains a source of E. coli O157:H7 for humans, but its overall relevance is likely to have subsided and significant caution should be exerted for temporal, geographical and consumers behaviour analysis. Health education programmes and regulatory actions are required to educate people, primarily children, on other STEC sources.

Abstract
This study investigated the presence of viable Mycobacterium avium ssp. paratuberculosis (MAP) in pasteurized milk produced by Italian industrial dairy plants to verify the prediction of a previously performed risk assessment. The study analyzed 160 one-liter bottles of pasteurized milk from 2 dairy plants located in 2 different regions. Traditional cultural protocols were applied to 500mL of pasteurized milk for each sample. The investigation focused also on the pasteurization parameters and data on the microbiological characteristics of raw milk (total bacterial count) and pasteurized milk (Enterobacteriaceae and Listeria monocytogenes). No sample was positive for MAP, the pasteurization parameters complied with European Union legislation, and the microbiological analysis of raw and pasteurized milk showed good microbiological quality. The results show that a 7-log (or >7) reduction could be a plausible value for commercial pasteurization. The combination of hygiene practices at farm level and commercial pasteurization yield very low or absent levels of MAP contamination in pasteurized milk, suggesting that pasteurized milk is not a significant source of human exposure to MAP in the dairies investigated.

Abstract
AIMS The present study aimed to determine, by multilocus sequence type (MLST), the heterogeneity level of Arcobacter butzleri isolates and to compare MLST and pulsed-field gel electrophoresis (PFGE) in terms of discriminatory power (DI) as well as unidirectional and bi-directional concordance. METHODS AND RESULTS Arcobacter butzleri isolates (N = 133) from dairy products and environmental samples, collected from dairy plants, were characterized by MLST and PFGE with SacII and classified in 29 sequence types (STs), 47 PFGE and 62 type strains (TS). Among the 119 alleles, 19 were previously unreported and the same for all the STs but two. A significant linkage disequilibrium was detected when the complete ST data set was analysed The DIs of MLST, PFGE and their combination were 0·937, 0·953 and 0·965 respectively. The adjusted Wallace coefficients between MLST and PFGE as well as PFGE and MLST were 0·535 and 0·720 respectively; the adjusted Rand coefficient was 0·612. CONCLUSIONS The A. butzleri studied population showed recombination to some degree. PFGE showed a DI higher than MLST. Both methods presented good concordance. The TS analysis seems to show persistence of the same strain on time and possible cross-contaminations between food and environmental sites. SIGNIFICANCE AND IMPACT OF THE STUDY This study provides insights in the A. butzleri population found in raw milk, cheese, and dairy production plants. The data suggest that MLST and PFGE genotypes correlate reasonably well, although their combination results in optimal resolution.

Abstract
The present study investigated the presence of Arcobacter spp. in industrial dairy plants. Between February and September 2013, pasteurized milk used for cheesemaking, processing and cleaning water, cheese, and environmental samples from different plant sites, including surfaces in contact or not in contact with food, were sampled. A total of 126 samples were analyzed by the cultural method and isolates were identified by multiplex PCR. Arcobacter spp. were isolated from 22 of 75 environmental samples (29.3%): of them, 22.7% were surfaces in contact with food and 38.7% surfaces not in contact with food. A total of 135 Arcobacter spp. isolates were obtained; of these, 129 and 6 were identified as Arcobacter butzleri and Arcobacter cryaerophilus, respectively. All food processing water and pasteurized milk samples were negative for Arcobacter species. We were not able to determine the primary source of contamination, but the isolation of both A. butzleri and A. cryaerophilus in surfaces in contact with food before and during manufacturing suggests that Arcobacter spp. are not or are only partially affected by routine sanitizing procedures in the industrial dairy plants studied. The efficacy of sanitizing procedures should be evaluated and further studies are needed to determine whether certain Arcobacter strains persist for long periods of time in industrial dairy plants and whether they can survive in different types of cheese in cases of postprocessing contamination.

Abstract
The objectives of this study were to investigate the presence of Campylobacter spp. and Arcobacter spp. in dairy herds authorized for the production and sale of raw milk and in a water buffalo dairy farm, and to test the antimicrobial susceptibility of the isolates. A total of 196 in-line milk filters were collected from 14 dairy farms (13 bovine and 1 water buffalo) for detection of Campylobacter spp. and Arcobacter spp. by microbiological culture. For each farm investigated, 1 isolate for each Campylobacter and Arcobacter species isolated was tested using the Etest method (AB Biodisk, Solna, Sweden) to evaluate the susceptibility to ciprofloxacin, tetracycline, chloramphenicol, ampicillin, erythromycin, and gentamicin. A total of 52 isolates were detected in 49 milk filters in 12 farms (85.7%) out of 14 and the isolates were identified as Campylobacter jejuni (6), Campylobacter hyointestinalis ssp. hyointestinalis (8), Campylobacter concisus (1), Campylobacter fetus ssp. fetus (1), Arcobacter butzleri (22), and Arcobacter cryaerophilus (14). The small number of isolates tested for antimicrobial susceptibility precludes any epidemiological consideration but highlights that all Campylobacter isolates were susceptible to macrolides, which are the first-choice drugs for the treatment of campylobacteriosis, and that resistance to fluoroquinolones and tetracycline was detected; for Arcobacter isolates, resistance to ampicillin and chloramphenicol was detected. The sale of raw milk for human consumption by self-service automatic vending machines has been allowed in Italy since 2004 and the presence of C. jejuni in in-line milk filters confirms that raw milk consumption is a significant risk factor for human infection. The high occurrence of emerging Campylobacter spp. and Arcobacter spp. discovered in dairy farms authorized for production and sale of raw milk represents an emerging hazard for human health.

Abstract
A quantitative risk assessment was developed to describe the risk of campylobacteriosis and hemolytic uremic syndrome (HUS) linked to consumption of raw milk sold in vending machines in Northern Italy. Exposure assessment considered the microbiological status of dairy farms, expected milk contamination, storage conditions from bulk tank to home storage, microbial growth during storage, destruction experiments, consumption frequency of raw milk, age of consumers, serving size, and consumption preference. The differential risk between milk handled under regulation conditions (4°C throughout all phases) and the worst field handling conditions was considered. The probability of Campylobacter jejuni infection was modeled with a single-hit dose-response beta-Poisson model, whereas for HUS an exponential dose-response model was chosen and two probabilities were used to model the higher susceptibility of children younger than 5 years old. For every 10,000 to 20,000 consumers each year, the models predicted for the best and worst storage conditions, respectively, 2.12 and 1.14 campylobacteriosis cases and 0.02 and 0.09 HUS cases in the 0- to 5-year age group and 0.1 and 0.5 HUS cases in the >5-year age group. The expected pediatric HUS cases do not differ considerably from those reported in Italy by the Minister of Health. The model developed may be a useful tool for extending the assessment of the risk of campylobacteriosis and HUS due to raw milk consumption at the national level in Italy. Considering the epidemiological implications of this study, the risk of illness linked to raw milk consumption should not be ignored and could be reduced by the use of simple measures. Boiling milk before consumption and strict control of temperatures by farmers during raw milk distribution have significant effects on campylobacteriosis and HUS and are essential measures for risk management.

Abstract
AIM To report the growth of glucosidase and phospholipase positive bacteria on agar Listeria according to Ottaviani and Agosti (ALOA) different from Listeria monocytogenes, Listeria ivanovii and Bacillus cereus. METHODS AND RESULTS Raw water-buffalo milk was analysed according to EN ISO 11290. Streaking of Fraser broth on ALOA resulted in green colonies with an opaque halo after 48 h at 30°C. Colonies were transferred onto Tryptone soya yeast extract agar and showed cultural characteristics atypical for L. monocytogenes. Results of confirmation tests according to EN ISO 11290 method: negative haemolysis test, weak positive camp test in correspondence with Staphylococcus aureus, no fermentation of rhamnose, fermentation of xylose. Gram staining showed tapered, curved, Gram-positive rods with subterminal to terminal ellipsoidal spores, 0.5-0.7 μm diameter 4-5 μm. API 50CH CHB kit (99.9% percentage of identification) and the sequence of the 833 bp PCR product (portion of 16S rRNA, generic primers 1492-r; p27-f) showed 97% identity with Bacillus circulans ATCC 4513 (GenBank AY724690). CONCLUSIONS Some B. circulans strains can grow on ALOA, according to ISO 11290, confirmation tests readily differentiate B. circulans from L. monocytogenes. SIGNIFICANCE AND IMPACT OF THE STUDY The different morphology of the colonies must be kept in mind to select true L. monocytogenes for confirmation test and to avoid overestimation of L. monocytogenes count.

Abstract
An epidemiological survey for the monitoring of bovine tuberculosis transmission was carried out in western Liguria, a region in northern Italy. Fifteen Mycobacterium bovis strains were isolated from 63 wild boar samples (62 from mandibular lymph nodes and 1 from a liver specimen). Sixteen mediastinal lymph nodes of 16 head of cattle were collected, and 15 Mycobacterium bovis strains were subsequently cultured. All M. bovis strains isolated from cattle and wild boars were genotyped by spoligotyping and by restriction fragment length polymorphism (RFLP) analysis with the IS6110 and IS1081 probes. All M. bovis strains showed the typical spoligotype characterized by the absence of the 39 to 43 spacers in comparison with the number in M. tuberculosis. A total of nine different clusters were identified by spoligotyping. The largest cluster included 9 strains isolated from wild boars and 11 strains isolated from cattle, thus confirming the possibility of transmission between the two animal species. Fingerprinting by RFLP analysis with the IS6110 probe showed an identical single-band pattern for 29 of 30 strains analyzed, and only 1 strain presented a five-band pattern. The use of IS1081 as a second probe was useful for differentiation of M. bovis from M. bovis BCG but not for differentiation among M. bovis strains, which presented the same undifferentiated genomic profile. In relation to the epidemiological investigation, we hypothesized that the feeding in pastures contaminated by cattle discharges could represent the most probable route of transmission of M. bovis between the two animal species. In conclusion, our results confirmed the higher discriminatory power of spoligotyping in relation to that of RFLP analysis for the differentiation of M. bovis genomic profiles. Our data showed the presence of a common M. bovis genotype in both cattle and wild boars, confirming the possible interspecies transmission of M. bovis.
