RESUMEN
The harmonisation of training programmes for infection control and hospital hygiene (IC/HH) professionals in Europe is a requirement of the Council recommendation on patient safety. The European Centre for Disease Prevention and Control commissioned the 'Training Infection Control in Europe' project to develop a consensus on core competencies for IC/HH professionals in the European Union (EU). Core competencies were drafted on the basis of the Improving Patient Safety in Europe (IPSE) project's core curriculum (CC), evaluated by questionnaire and approved by National Representatives (NRs) for IC/HH training. NRs also re-assessed the status of IC/HH training in European countries in 2010 in comparison with the situation before the IPSE CC in 2006. The IPSE CC had been used to develop or update 28 of 51 IC/HH courses. Only 10 of 33 countries offered training and qualification for IC/HH doctors and nurses. The proposed core competencies are structured in four areas and 16 professional tasks at junior and senior level. They form a reference for standardisation of IC/HH professional competencies and support recognition of training initiatives.

BACKGROUND: Uncontrolled studies show fatigue, anorexia, depression, and mortality are associated with low testosterone in men with cancer. Testosterone replacement improves quality of life and diminishes fatigue in patients with non-cancer conditions. The primary objective was to evaluate the effect of testosterone replacement on fatigue in hypogonadal males with advanced cancer, by the Functional Assessment of Chronic Illness Therapy-Fatigue subscale (FACIT-Fatigue) at day 29. METHODS: This is a randomized, double-blinded placebo-controlled trial. Outpatients with advanced cancer, bioavailable testosterone (BT) <70 ng/dL and fatigue score >3/10 on the Edmonton Symptom Assessment Scale were eligible. Intra-muscular testosterone or sesame seed oil placebo was administered every 14 days to achieve BT levels 70-270 ng/dL. RESULTS: Sixteen placebo and 13 testosterone-treated subjects were evaluable. No statistically significant difference was found for FACIT-fatigue scores between arms (-2 ± 12 for placebo, 4 ± 8 for testosterone, p = 0.11). Sexual Desire Inventory score (p = 0.054) and performance status (p = 0.02) improved in the testosterone group. Fatigue subscale scores were significantly better (p = 0.03) in those treated with testosterone by day 72. CONCLUSIONS: Four weeks of intramuscular testosterone replacement in hypogonadal male patients with advanced cancer did not significantly improve quality of life. Larger studies of longer duration are warranted.

Intraosseous ganglion (IOG) is the most frequently occurring bone lesion within the carpus and is often an incidental finding on radiographs obtained for other reasons. Two types of IOG have been described: an "idiopathic" form (or type I), the pathogenesis of which has not been completely clarified, and a "penetrating" form (or type II), caused by the intrusion of juxtacortical material (often a ganglion cyst of the dorsal soft tissue) into the cancellous bone compartment. The differential diagnosis for IOG is wide-ranging and complex, including lesions of posttraumatic (posttraumatic cystlike defects), degenerative (subchondral degenerative cysts), inflammatory [cystic rheumatoid arthritis, chronic tophaceous gout (CTG)], neoplastic (benign primary bone tumours and synovial proliferative lesions), ischaemic (Kienböck's disease or avascular osteonecrosis of the lunate) and metabolic (amyloidosis) origin. Multimodality imaging of IOGs is a useful diagnostic tool that provides complete morphological characterisation and differentiation from other intraosseous cystic abnormalities of the carpus. Thin-slice multidetector computed tomography (MDCT) can provide high-spatial-resolution images of the cortical and cancellous bone compartments, allowing detection of morphological findings helpful in characterising bone lesions, whereas magnetic resonance (MR) imaging can simultaneously visualise bone, articular surfaces, hyaline cartilage, fibrocartilage, capsules and ligaments, along with intra- and periarticular soft tissues.

Gout, calcium pyrophosphate dihydrate (CPPD) deposition disease, and calcium hydroxyapatite deposition disease (HADD) are the three most common crystal-induced arthropathies. Multimodality imaging may help in their diagnosis, and is useful for a precise and comprehensive assessment and grading of the related osteoarticular damage. Plain film radiography, due to its low cost and wide availability, is the first imaging technique to be used in crystal deposition diseases, providing well-known and specific findings for CPPD deposition disease and HADD, while it may undergrade the early osteoarticular lesions in gouty patients. Ultrasonography (US) is a radiation-free approach that accurately depicts crystal deposits in cartilage, peri- and intra-articular soft tissues, but it does not give a panoramic view of the affected joints. Cross-sectional imaging techniques can examine crystal deposits in the spine and axial joints. CT has the potential to distinguish monosodium urate (MSU) crystals from calcium containing crystals, due to their different attenuation values. MRI may demonstrate synovitis, erosions and bone marrow edema in gouty patients and it may differentiate tophi from other soft tissue nodules due to its high contrast resolution and power of tissue characterization.

OBJECTIVES: To describe the MRI features of gout tophi in the soft-tissues or joints of the limbs by low-field extremity-dedicated MRI. METHODS: Nine consecutive patients, 8M/1W, affected by chronic tophaceous gout were studied. Mean patients' age was 71.3±11.5 years, mean disease duration 98.1±44.9 months, and mean serum uric acid concentration 9.2±2.8 mg/L. Diagnosis was based on the ACR classification criteria for gout, and by identification of MSU crystals in the tophi and synovial fluid. Conventional radiograms and MRI with an extremity-dedicated system were obtained of the joint areas involved by tophi. RESULTS: At T1 weighted MRI images, all tophi showed a homogeneous intermediate signal intensity, similar to that of muscle. Conversely, in T2 weighted images, a wide spectrum of signal intensity patterns was observed. The pattern of contrast enhancement was variable from intense homogeneous to peripheral and heterogeneous. Capsulo-ligamentous structures were often thickened and degenerated and, on occasion, could be recognised as inhomogeneous, hypointense ribbon-shaped elements in the context of the tophus. In only two cases, tendons were infiltrated by tophaceous matter. Bone marrow oedema (BME) and erosions were seen in 8 out of 10 bones adjacent to tophi. CONCLUSIONS: The MRI appearance of gout tophi using an extremity-dedicated machine is similar to that described in the literature using whole body machines. BME adjacent to the tophus was a frequent finding. This technique may occasionally help in the differential diagnosis of nodules and in the follow-up of the disease. It also represents a useful tool to investigate the pathogenesis of gout and to better understand its clinical progression.

Healthcare-associated infection (HCAI), patient safety, and the harmonization of related policies and programmes are the focus of increasing attention and activity in Europe. Infection control training for healthcare workers (HCWs) is a cornerstone of all patient safety and HCAI prevention and control programmes. In 2009 the European Centre for Disease Prevention and Control (ECDC) commissioned an assessment of needs for training in infection control in Europe (TRICE), which showed a substantial increase in commitment to HCAI prevention. On the other hand, it also identified obstacles to the harmonization and promotion of training in infection control and hospital hygiene (IC/HH), mostly due to differences between countries in: (i) the required qualifications of HCWs, particularly nurses; (ii) the available resources; and (iii) the sustainability of IC/HH programmes. In 2013, ECDC published core competencies for infection control and hospital hygiene professionals in the European Union and a new project was launched ['Implementation of a training strategy for infection control in the European Union' (TRICE-IS)] that aimed to: define an agreed methodology and standards for the evaluation of IC/HH courses and training programmes; develop a flexible IC/HH taxonomy; and implement an easily accessible web tool in 'Wiki' format for IC/HH professionals. This paper reviews several aspects of the TRICE and the TRICE-IS projects.

Thanks to its intrinsic high spatial resolution, ultrasound is an ideal imaging modality for examining very thin, superficial structures, and this makes it very helpful in the evaluation of extrinsic carpal ligaments. These structures, which arise from the radius and ulna and insert on the carpal bones, are extremely important for wrist stability. Previous studies have assessed the use of ultrasound to study the extrinsic carpal ligaments in cadavers, healthy asymptomatic subjects, and patients with rheumatoid arthritis. In the present report, we review the normal anatomy, biomechanics, and ultrasound appearance of these ligaments.
RESUMEN
PURPOSE: The efficacy of platelet-rich plasma (PRP) in the treatment and healing of chronic tendinopathy through stimulation of cell proliferation and total collagen production has been demonstrated by both in vitro and in vivo studies. The aim of this study is to evaluate the effectiveness of ultrasound (US)-guided autologous PRP injections in patellar and Achilles tendinopathy. MATERIALS AND METHODS: Autologous PRP was injected under US-guidance into the Achilles and patellar tendons (30 Achilles tendons, 28 patellar tendons) in 48 prospectively selected patients (30 males, 18 females, mean age 38 ± 16 years, range 20-61 years). All patients were previously evaluated according to the Victoria Institute of Sport Assessment (VISA) scale, which assessed pain and activity level, and they all underwent US of the tendon before treatment and at follow-up after 20 days and 6 months. Statistical analysis was performed with Chi-square and Wilcoxon tests. RESULTS: 20 days after PRP injection the patients presented a non-significant improvement of clinical symptoms. At the 6-month follow-up VISA score increased from a mean value of 57-75.5 (p < .01). US evaluation revealed a reduction of hypoechoic areas in 26 tendons (p < .01) associated with a widespread improvement of fibrillar echotexture of the tendon and reduced hypervascularity at power Doppler. CONCLUSION: PRP injection in patellar and Achilles tendinopathy results in a significant and lasting improvement of clinical symptoms and leads to recovery of the tendon matrix potentially helping to prevent degenerative lesions. US-guidance allows PRP injection into the tendon with great accuracy.
RESUMEN
PURPOSE: To characterize the rotator cable high-resolution ultrasound appearance in asymptomatic shoulders of volunteers of different age. MATERIALS AND METHODS: IRB approval and volunteers' written consent was obtained. Excluding subjects with known shoulder affections, we screened 24 asymptomatic volunteers. Supraspinatus and infraspinatus tendons high-resolution ultrasound evaluation was performed according to standard scan protocols, further excluding shoulders with partial/full-thickness cuff tears. Thus, we studied 24 shoulders in 12 young volunteers (age range 21-39 years, mean age 33 ± 8 years) and 21 shoulders in 11 elderly volunteers (age range 62-83 years, mean age 75 ± 45 years). For each shoulder, we noted rotator cable visibility and its thickness and width. Fisher's and U Mann-Whitney statistics were used. RESULTS: Rotator cable was less frequently detected in young than in elderly volunteers (5/24 vs. 11/21 shoulders; P = 0.034). When detected, rotator cable was significantly thicker in young (range 1.2-1.5 mm, mean thickness 1.3 ± 0.1 mm) than in elderly (range 0.9-1.4 mm, mean thickness 1.2 ± 0.1 mm) volunteers (P = 0.025), while its width was not significantly different in young (range 4.5-7.1 mm, mean 5.6 ± 1.1 mm) compared to elderly (range 2.5-7.1 mm, mean 4.2 ± 1.4 mm) volunteers (P = 0.074) although a tendency can be highlighted. CONCLUSIONS: Ultrasound demonstrated the different consistency of rotator cable in young and elderly asymptomatic patients, with high interobserver reproducibility.
RESUMEN
PURPOSE: We reassessed the incidence of mucocele of the residual cystic duct in our series of orthotopic liver transplantation (OLT) patients. MATERIAL AND METHODS: We examined a series of 283 liver transplants with end-to-end choledocho-choledocal anastomosis (263 patients, 163 men and 80 women, 24-65 years old), performed at the II Surgical Department of the University of Bologna from May 1986 to April 1999 and subsequently followed-up in our Institute. All patients were examined with gray-scale and color Doppler US and some also underwent CT and CT cholangiography. RESULTS: An anechoic ovoidal structure just before the portal vein and in proximity of the main bile duct was found in 13 patients. US and CT findings, the latter when available, led us to make a diagnosis of nonobstructive mucocele of the cystic duct. The radiological diagnosis was eventually confirmed by clinical and surgical findings. DISCUSSION AND CONCLUSIONS: In our series the incidence of this complication was 4.5%, a slightly higher value than those reported in the literature. Cystic duct mucocele cannot be considered an uncommon complication and should thus be more carefully searched for by operators. In our experience this complication never required reoperation for cholestasis.

PURPOSE: In this study we compared duplex Doppler sonography, conventional angiography and CT angiography for the evaluation of hepatic arterial complications following orthotopic liver transplantation (OLT). MATERIAL AND METHODS: CT angiography, with Maximum Intensity Projection (MIP) and Volume Rendering reconstructions, was performed in 11 patients with well-grounded suspect of hepatic artery stenosis or thrombosis after routine duplex Doppler examination. Eight patients underwent conventional angiography. RESULTS: CT detected three out of four duplex doppler false positives and confirmed the diagnostic suspect in four cases. In two cases it showed a shift of the blood flow towards the splenic artery with hepatic hypoperfusion. In one case a wrong delay rendered the study unuseful. In seven out of eight patients conventional angiography confirmed CT angiography findings. DISCUSSION. The follow up of OLT arterial complications is now performed with duplex doppler sonography; this technique has a satisfactory sensitivity and specificity, but far from 100%. Therefore in some patients the diagnosis of arterial obstruction might be delayed, with the risk of serious complications; in other cases with ultrasonographic false positive findings, useless angiographic examinations are performed. In our experience CT angiography proved to be a precious tool, which might be included in the diagnostic algorithm of arterial complications after OLT. Particularly CT angiography seems to be suitable for the cases of discordance between clinical and duplex doppler findings, to improve the overall diagnostic accuracy. CONCLUSION: In our experience CT-angiography proved to be accurate and satisfactory as a second step examination after duplex-doppler in the diagnostic algorythm of adult OLT arterial complications.

Whole blood folate level is a superior indicator of folate nutritional status than serum/plasma level. Problems with and lack of confidence in results of current whole blood folate assays have limited its popularity for assessing folate nutritional status. Here, an acid extraction GCMS detection method that measures total folate whole blood is presented. Folates are released from the matrix of whole blood and cleaved to para-aminobenzoic acid (pABA) by acid hydrolysis in the presence of [(13)C(6)]pABA as internal standard (IS). The hydrolysate is passed over a C18 resin to remove heme. The pABA isotopomers are ethyl esterified, isolated on C18 resin, and trifluoroacetylated. Following normal-phase HPLC separation, the isotopomers are silylated to their tBDMS derivatives. The abundance of these derivatives are measured at m/z 324 for [(13)C(6)]pABA as IS and m/z 318 for pABA from whole blood folate. Our method uses readily available chemicals and our results agree well with those using Lactobacillus casei, the current gold standard reference assay. The presence of folate analogs (methotrexate) or antibacterials (sulfonamines) does not affect our method. This feature makes it useful in monitoring folate status of patients undergoing chemotherapy. Before using our method, pABA supplements must be discontinued for a few days.
