Abstract
INTRODUCTION Ruminants are regarded as the natural reservoir for Shiga toxin-producing Escherichia coli (STEC), especially of serogroup O157. MATERIALS AND METHODS During 2011 and 2012, 320 samples (160 faecal samples from the rectum and 160 hide samples from the brisket area) were collected from 160 cattle at slaughter in Northern Italy during warm months (May to October). Cattle were reared in different farms and their age at slaughter ranged between nine months and 15 years, most of them being culled cattle (median age: six years; average age: 4.6 years). Samples were tested by immunomagnetic-separation technique for E coli O157 and O26 and by a screening PCR for stx genes followed by cultural detection of STEC. The virulence genes stx1, stx2, eae, and e-hlyA were detected and among stx2-positive isolates the presence of the stx2a and stx2c variants was investigated. RESULTS Twenty-one of 160 cattle (13.1 per cent; 95 per cent CI 8.3 to 19.4 per cent) were found to be faecal carriers of STEC. STEC O157 was found in 10 (6.3 per cent) samples, STEC O26 in six (3.8 per cent) and STEC O111 in one (0.6 per cent). Four isolates (2.5 per cent) were O not determined (OND). Six out of 160 (3.8 per cent; 95 per cent CI 1.4 to 8.0 per cent) hide samples were positive for STEC; four hides (2.5 per cent) were contaminated by STEC O157 and two (1.3 per cent) by STEC O26. In three cattle (1.9 per cent) STEC from both faeces and hides were detected. Among STEC O157, 87.5 per cent of them carried the stx2c gene and 12.5 per cent carried both stx1 and stx2c genes. No O157 isolate harboured stx2a variant. STEC O26 and O111 carried the stx1 gene only. One OND strain carried both the stx2a and stx2c genes. CONCLUSIONS This study shows that STEC O157 from cattle can harbour the stx2c variant, which is associated with haemolytic uraemic syndrome in humans, and that cattle hides may be a source of human pathogenic STEC O157 and O26 in the slaughterhouse environment.

Abstract
Yersinia enterocolitica is recognized as an etiological agent of gastroenteritis, lymphadenitis, and chronic sequelae. During 2006 and 2007, 205 samples (125 pork and 80 chicken meats) were collected in Italy and tested for detection and most-probable-number (MPN) enumeration of Y. enterocolitica organisms. The microorganism was isolated from 45 samples (21.9%): 19 (15.2%) pork samples and 26 (32.5%) chicken samples. Y. enterocolitica MPN contamination levels were low, ranging from 0.30 to 1.50/g. Most (94.4%) Y. enterocolitica strains were biotype 1A (serotypes O:3; O:5; O:6,30; O:6,30-6,31; O:7,8-8-8,19; O:8; O:9; O:25,35; O:36; and O nontypeable), and 5.6% of the isolates were bioserotype 2/O:9. All isolates were tested for yadA, ail, inv, ystA, and ystB virulence sequences. The yadA gene was detected in two strains (3.7%) isolated from chicken samples: one Y. enterocolitica 2/O:9 yadA+ ail+ ystA+, and one Y. enterocolitica 1A/O:7,8-8-8,19 yadA+ inv+ ystB+. Two (3.7%) 2/O:9 strains, isolated from pork products, were ail+ ystA+. Most biotype 1A strains were ystB+ (84.3%) and inv+ (39.2%). All strains were sensitive to cefotaxime, ciprofloxacin, chloramphenicol, nalidixic acid, streptomycin, sulfonamide, tetracycline, trimethoprim, and trimethoprim-sulfamethoxazole. Resistance to gentamicin and aztreonam was observed in 1.9% of the isolates. High levels of resistance were detected toward amoxicillin-clavulanic acid (27.8%), ampicillin (75.9%), and erythromycin (100%). The authors hypothesize that Y. enterocolitica pathogenic biotypes are rather uncommon in foods when compared with their isolation rates from animal sources and that chicken meat could be contaminated as well as pig meat and its derived products.

Abstract
OBJECTIVES Restless legs syndrome (RLS) occurs in polyneuropathy with small fiber involvement, possibly as a peculiar form of neuropathic pain; however, the relationship between pain and RLS has been poorly investigated in polyneuropathy. DESIGN, SETTING, AND PATIENTS We evaluated retrospectively the occurrence of RLS in 102 consecutive patients with polyneuropathy manifesting with neuropathic pain or dysesthesia, referred to the Neuromuscular Center, using the National Institutes of Health criteria for RLS. The patients were classified in subgroups characterized respectively by allodynia (hyperphenomena), with reported unpleasant sensations evoked by tactile stimuli, and hypoalgesia (hypophenomena), with absent pain sensation to pinprick, according to putative mechanisms of pain. RESULTS RLS was present in 41/102 patients (40.2%). It was significantly more frequent in the "hypoalgesia" (23/37) than in the "allodynia" subgroup (9/31; P = 0.008) and in the not classifiable cases (9/34; P = 0.004). CONCLUSIONS RLS is frequent in painful polyneuropathy and is significantly associated with decreased small fiber input, thus nociceptive deafferentation may represent a factor interacting with RLS "generators," possibly at spinal level. We suggest that overactivity of the spinal structures implicated in RLS may be triggered by nociceptive deafferentation in a subgroup of patients with painful polyneuropathy. Our findings, prompting a mechanistic characterization of RLS associated with painful polyneuropathy, have to be confirmed in a prospective study.

Abstract
Restless legs syndrome (RLS) is a condition characterized by discomfort at rest and urge to move focused on the legs. RLS may occur as an idiopathic, often hereditary condition (primary RLS), or in association with medical conditions (secondary RLS) including iron deficiency, uremia, and polyneuropathy. Current understanding of the pathophysiology of RLS points to the involvement of three interrelated components: dopaminergic dysfunction, impaired iron homeostasis, and genetic mechanisms. The diagnosis of RLS is made according to the consensus criteria by a National Institutes of Health panel: 1) an urge to move the legs, usually accompanied by uncomfortable sensations; 2) beginning or worsening during rest; 3) relieved by movement; and 4) worse, or only occurring, in the evening or at night. The differential diagnosis of RLS aims to: 1) distinguish RLS from other disorders with RLS-like symptoms and 2) identify secondary forms, with investigation of underlying diseases. The treatment of RLS demands a clinical evaluation to rule out and cure causes of secondary RLS, including iron supplementation when deficient, and to eliminate the triggering factors. The presence of neuropathy should be especially investigated in nonhereditary, late-onset RLS, in view of a possible treatment of the underlying disease. The first line treatment for idiopathic RLS is represented by dopamine agonists, in particular nonergot-derived ropinirole and pramipexole, whereas ergot dopamine agonists (cabergoline and pergolide) are no longer in first-line use given the risks of cardiac valvulopathy. Although no comparative trials have been published, a meta-analysis of pramipexole versus ropinirole suggests differences in efficacy and tolerability favoring pramipexole.

Abstract
After an introduction concerning the structure of Italian and European Veterinary Offices, the authors outline the features of food production in the provinces of Parma and Reggio Emilia, particularly concerning the role of veterinary hygienists and of the other professionals operating along the food chain. The authors underline that veterinarians should improve their managerial skills, together with the technical and legal competences acquired during the bachelor course, (eventually integrated by stages in food factories) and undertake continuous post-university improvement, enabling them to face the competition presented by new professionals.

Abstract
As the occurrence of restless legs syndrome (RLS) in diabetes is controversial, the aim of this study was to assess the prevalence of RLS in a cohort of patients with diabetic neuropathy and to analyze the features of the associated neuropathy. We investigated the occurrence of RLS diagnosed in accordance with the criteria of the International Restless Legs Syndrome Study Group in a cohort of patients with polyneuropathy and mononeuropathy multiplex associated with diabetes mellitus (DM), or impaired glucose tolerance (IGT), or impaired fasting glucose (IFG) in a retrospective study. RLS was present in 33/99 patients with neuropathy associated with DM/IGT/IFG (84 with distal polyneuropathy and 15 with multiple mononeuropathy). Comparing patients with or without RLS, small fiber sensory neuropathy was more common in the RLS patients (15/33 vs. 15/66), as were symptoms of burning feet (10/33 vs. 6/66). In several patients, RLS was responsive to neuropathic pain medications. The frequent occurrence of RLS in association with thermal dysesthesias may reflect the involvement of small sensory fibers in the form of hyperexcitable C fibers or A-delta fiber deafferentation. We suggest that RLS may be triggered by abnormal sensory inputs from small fibers, especially involved in neuropathy associated with DM/IGT/IFG. Our data show that RLS is a relevant feature of diabetic neuropathy, as a frequent and potentially treatable manifestation of small fiber involvement in the course of DM and IGT/IFG.

Abstract
Restless legs syndrome (RLS), diagnosed according to the International RLS Study Group criteria, was investigated in 97 consecutive patients with polyneuropathy and found in 29 patients. RLS patients were more often women (22 of 29 vs. 33 of 68; P = 0.015), mainly with sensory neuropathy of small fiber type (15 of 29 vs. 16 of 68; P = 0.009). Changes of sensory action potentials were significantly less severe in RLS patients. In the RLS group, acquired neuropathies, and in particular dysimmune neuropathies, were significantly more frequent (27/29 vs. 46/68; P = 0.009). Thus, RLS is frequent in acquired polyneuropathy of sensory type and mild entity, mainly in women.

Abstract
BACKGROUND AND OBJECTIVE Cryoglobulinaemic neuropathy (CN) is probably common, as it is usually related to HCV infection. The aim of this study was to delineate the clinical spectrum of CN in a large series and to investigate the factors influencing its expression. METHODS Seventy one consecutive patients (12 men, 59 women), diagnosed as having CN on the basis of clinical features of neuropathy, clinical and serological findings of mixed cryoglobulinaemia, and exclusion criteria, were identified during a six year period. All patients underwent clinical examination, and electrophysiological and laboratory investigations. RESULTS Results of the patients with "pure" CN (n = 54) and those with comorbidities (n = 17) were evaluated separately. Of the former 76% had sensory neuropathy (including selective small fibre sensory neuropathy (SFSN) in 14 patients), 15% had sensorimotor polyneuropathy, and 9% had mononeuritis multiplex. The pattern of distribution was similar in the patients with comorbidities. In 30/54 patients, CN was the first manifestation of cryoglobulinaemia. Patients with mild cryoglobulinaemic syndrome had sensory neuropathy more frequently than patients with active syndrome (p < 0.001), in particular SFSN (p < 0.001). The latter group had more severe features, with significantly more cases of reduced or absent motor (p = 0.028) and sensory action potentials (p < 0.001), and a tendency towards higher Rankin scores (p = 0.06). CONCLUSIONS Sensory neuropathy, often in the form of SFSN, is by far the commonest form of CN. Cryoglobulinaemia should be vigorously investigated in the diagnosis of sensory neuropathy, especially in older women. Activity of the cryoglobulinaemic syndrome is a major factor influencing the clinical expression and severity of CN.

Abstract
Between September 2001 to June 2002, 145 samples of bovine caecal content were collected at slaughter for verocytotoxin-producing Escherichia coli (VTEC) serogroups O157 and non-O157 detection. For E. coli O157 the immunomagnetic-separation technique was performed. The enterohaemolytic phenotype was the target for non-O157 VTEC identification. The vero cell assay (VCA) was performed for toxic activity detection. The genomic sequence for VT1, VT2 and intimin (vt1, vt2, eae genes) were identified by PCR analysis. Eight VTEC O157 and eight non-O157 VTEC isolates were detected. VTEC O157, eae-positive strains were shed by 9.7% of feedlot cattle and by 2.5% of dairy cows. Non-O157 VTEC, eae-negative isolates were detected in the intestinal content of 12.5% dairy cows and of 2.1% feedlot cattle. VTEC-shedding cattle came from 18.1% of the farms included in the study. From cattle faeces, VTEC O91:H- (VT2-positive, eae-negative), responsible of human diarrhoeal disease in Europe, was recovered. Other VTEC serogroups identified in the present study were O74, O109, O110, O116, and O117.

Abstract
From December 1999 to December 2000, 150 pigs were randomly selected in two large abattoirs of northern Italy. Caecal material and carcass swabs were collected and examined for Salmonella, Yersinia enterocolitica, and Escherichia coli O157. Tonsils were examined for Salmonella and Y. enterocolitica. Salmonella was isolated from the intestinal content of 55 (36.7%) specimens, from 8 (5.3%) tonsils, and from 9 (6.0%) carcasses. Ten different serotypes were detected; the more common were Salmonella derby (37.8%), Salmonella bredeney (21.6%), and Salmonella typhimurium (14.8%). S. typhimurium isolates that belonged to phage-types DT104 and DT208 were 45% and 27.3%, respectively; 18.2% belonged to U302 and 9.1% were non-typeable. Y. enterocolitica was detected in the intestinal matter of 6 (4.0%) slaughtered pigs and in 22 (14.7%) tonsils; however, this pathogen was not found on carcasses. The majority of Y. enterocolitica isolates (82.1%) belonged to serotype O:3 biotype 4, one (3.6%) belonged to serotype O:9, and 13% did not belong to any known biotype. Verocytotoxin-producing E. coli (VTEC) O157 was isolated from the intestinal content of one (0.7%) slaughtered pig and from one (0.7%) carcass; four (2.7%) faecal samples contained E. coli O157 strains negative for the presence of both eae and VT genes.
