RESUMEN
In the last decade, interest in monitoring and managing plastic pollution has greatly increased. This study compared levels of microplastic contamination in stomachs of Mugilidae fish, suggesting this family as a target for plastic pollution monitoring in areas with different degrees of anthropisation. Two sites characterised by low and high anthropic impact, a fishpond (S'Ena Arrubia, Italy) and a port (Genoa, Italy), respectively, were compared. This study highlighted a stronger microplastic contamination in the port, with a higher percentage of fish showing the presence of microplastics and a larger polymeric variability compared to the fishpond. The microplastic number in fish from the port was higher than in the literature, but it was not significantly different from S'Ena Arrubia in terms of the microplastic percentage found in single individuals. Biomonitoring of microplastic contamination in Mugilidae fish resulted in a valid tool for the investigation of areas differently affected by human activity.

PURPOSE: To assess a correlation between the shrinkage of the fibroid and the course of the symptoms. MATERIAL AND METHODS: Fourteen patients with symptomatic uterine leiomyomas (mean fibroid volume: 111.45 cm3) underwent percutaneous microwave ablation. Contrast-enhanced MRI follow-up was performed before and after treatment to evaluate the volume shrinkage. Two scores obtained from the Uterine Fibroids Symptom and Quality of Life questionnaire were used to perform a clinical follow-up to evaluate the symptoms and the quality of life at baseline, and at 3, 6 and 12 months after treatment. RESULTS: All patients were treated, no complications occurred. During a mean MR follow-up of 8.1 months we observed shrinkage of the fibroids in all patients (mean 70.3 cm3). During 12 months clinical follow-up, we observed a significant improvement of symptoms and an excellent improvement of quality of life (p < .001). CONCLUSION: Uterine fibroids percutaneous microwave ablation is a safe tool to obtain a significant improvement in quality of life for all the patients of our cohort.

To describe radiographic key patterns on Chest X-ray (CXR) in patients with SARS-CoV-2 infection, assessing the prevalence of radiographic signs of interstitial pneumonia. To evaluate pattern variation between a baseline and a follow-up CXR. 1117 patients tested positive for SARS-CoV-2 infection were retrospectively enrolled from four centers in Lombardy region. All patients underwent a CXR at presentation. Follow-up CXR was performed when clinically indicated. Two radiologists in each center reviewed images and classified them as suggestive or not for interstitial pneumonia, recording the presence of ground-glass opacity (GGO), reticular pattern or consolidation and their distribution. Pearson's χ2 test for categorical variables and McNemar test (χ2 for paired data) were performed. Patients mean age 63.3 years, 767 were males (65.5%). The main result is the large proportion of positive CXR in COVID-19 patients. Baseline CXR was positive in 940 patients (80.3%), with significant differences in age and sex distribution between patients with positive and negative CXR. 382 patients underwent a follow-up CXR. The most frequent pattern on baseline CXR was the GGO (66.1%), on follow-up was consolidation (53.4%). The most common distributions were peripheral and middle-lower lung zone. We described key-patterns and their distribution on CXR in a large cohort of COVID-19 patients: GGO was the most frequent finding on baseline CXR, while we found an increase in the proportion of lung consolidation on follow-up CXR. CXR proved to be a reliable tool in our cohort obtaining positive results in 80.3% of the baseline cases.

BACKGROUND: Prostate cancer is the first cancer diagnosis in men. European Association of Urology (EAU) Guidelines for Prostate Cancer underline the importance of screening, performed through PSA testing on all men with more than 50 years of age and before on men with risk factors. The diagnosis is still histopathologic, and it is done on the basis of the findings on biopsy samples. MATERIALS AND METHODS: Fusion biopsy is a relatively new technique that allows the operator to perform the biopsies in office instead of the MRI gantry, without losing the detection capability of MRI. The T2-wighted images obtained during a previous mpMRI are merged with the real-time ones of the TRUS. RESULTS: Fusion biopsy in comparison with the systematic standard biopsy has a better detection rate of clinically significant cancers and of any cancers. CONCLUSION: EAU 2020 guidelines still do offer a list of indications of when the biopsy should be performed, but it still appeared to be overperformed. The aim of our study is to underline how, in accordance with the recent literature result, fusion biopsy has showed a better detection rate of any cancer and clinically significant disease with a reduced numbers of samplings, and no substantial difference between the multiple software.

Clinical manifestation of coronavirus disease (COVID-19) varies from asymptomatic to severe clinical forms that can result in acute respiratory distress syndrome or in multiple organ dysfunction syndromes. There are no guidelines, based on randomized controlled trials, for the treatment of COVID-19 patients. The treatment is based on antiviral drugs, invasive and non-invasive ventilation supports, and anticoagulant therapy. This is a pictorial essay covering the multiple adverse events encountered during the treatment of COVID-19 patients in an area with a high pandemic incidence. Adverse events are defined as unexpected events following treatment for the infection. The cases described would be useful in aiding early diagnosis, limiting and improving the management of serious complications for patients, and allowing rapid and appropriate treatment.
RESUMEN
Aim: To differentiate Warthin tumors (WTs) and pleomorphic adenomas (PAs) measuring heterogeneity of intravoxel incoherent motion (IVIM) and dynamic-contrast enhanced-magnetic resonance imaging biomarkers. Methods: Volumes of interest were traced on 18 WT and 18 PA in 25 patients. For each IVIM and dynamic-contrast enhanced biomarker, histogram parameters were calculated and then compared using the Wilcoxon-signed-rank test. Receiver operating characteristic curves and multivariate analysis were employed to identify the parameters and their pairs with the best accuracy. Results: Most of the biomarkers exhibited significant difference (p < 0.05) between PA and WT for histogram parameters. Time to peak median and skewness, and D* median and entropy showed the highest area under the curve. No meaningful improvement of accuracy was obtained using two features. Conclusion: IVIM and dynamic-contrast enhanced histogram descriptors may help in the classification of WT and PA.

The article Microplastics in seawater: sampling strategies, laboratory methodologies, and identification techniques applied to port environment.
RESUMEN
The European Interreg Italy-France 2014-2020 Maritime Project SPlasH! (Stop to Plastics in H2O!) focused on the study of microplastics (MPs) in the marine port environment to evaluate their presence, abundance, and mechanisms of diffusion to the open sea. In the framework of this project, a worldwide review of 74 studies was carried out, providing an overview of MP investigation techniques, focusing on sampling strategies, laboratory methodologies, and identification of MPs collected in seawater, and specifically evaluating their applicability to the marine port environment. Nets were the most commonly used device for MP surface sampling, but their use can be difficult in narrow spaces within the port basins, and they must be coupled to discrete sampling devices to cover all port basins. In the laboratory, density separation (NaCl, ZnCl2, NaI, sodium lauryl sulfate (SLS)), filtration (polycarbonate, polyamide, glass, cellulose, ANOPORE inorganic membrane filters), sieving, visual sorting, and digestion methods (acidic, enzymatic, alkaline, oxidative) were used to separate MPs from seawater. Digestion becomes essential with water samples with great inorganic and organic loads as deriving from a port. Although many studies are based only on visual MP identification under a microscope, analytical identification techniques unequivocally determine the particle nature and the identity of the plastic polymers and are necessary to validate the visual sorting of MPs. Fourier-transform infrared spectroscopy (FTIR) is the most used analytical identification technique.

BACKGROUND: To evaluate role of interventional radiology (IR) in post-surgical haemorrhagic complications of prostatectomy. METHODS: A retrospective study was performed. From April 2015 to January 2018, 10 patients referred to IR Department for haemorrhagic complications post radical prostatectomy (RP). All patients (mean age: 68.5 years; range, 58-85 years) were successfully treated with superselective trans-arterial embolization. We evaluated technical and clinical success and post procedural complications. RESULTS: Technical and clinical success was 100% (10/10) and no major complications were identified. No complications related to the endovascular procedures occurred. No recurrences during follow-up (8-20 months) were observed. Among minor complications, only 20% (2/10) developed mild post embolization syndrome. CONCLUSIONS: The endovascular management of significant haemorrhage after prostatectomy is safe and long-term effective, with no major ischaemic events associated to embolization.
RESUMEN
Bile duct injuries are among the most feared complications after pancreatic surgery. Most of these surgical complications are related to iatrogenic injuries and include bile leakage, biliary duct obstruction or stricture and infection. A wide range of Interventional Radiology treatment options are currently available. The options include percutaneous transhepatic cholangiography (PTC), percutaneous transhepatic biliary drainage (PTBD), percutaneous balloon dilatation and stenting, image-guided percutaneous abscess drainage. The purpose of this review is to describe the current evidence in this continuously evolving field.
RESUMEN
Postoperative bile leakage is a common complication of abdominal surgical procedures and a precise localization of is important to choose the best management. Many techniques are available to correctly identify bile leaks, including ultrasound (US), computed tomography (CT) or magnetic resonance imaging (MRI), being the latter the best to clearly depict "active" bile leakages. This paper presents the state of the art algorithm in the detection of biliary leakages in order to plan a percutaneous biliary drainage focusing on widely available and safe contrast agent, the Gb-EOB-DPA. We consider its pharmacokinetic properties and impact in biliary imaging explain current debates to optimize image quality. We report common sites of leakage after surgery with special considerations in cirrhotic liver to show what interventional radiologists should look to easily detect bile leaks.
RESUMEN
AIM: To evaluate the incidence of in-stent restenosis (ISR) at 12-month follow-up, in patients treated with new dual-layer Roadsaver (Terumo Corp, Tokyo, Japan) carotid artery stent (CAS). MATERIALS AND METHODS: Thirteen patients underwent CAS and received a Roadsaver. Neurological examination was performed in all patients. Carotid stenosis was revealed by Doppler ultrasound (DUS) and multidetector CT (MDCT) scan. Four patients presented a peak systolic velocity (PSV) between 130 and 150 cm/s, six a PSV between 150 and 180 cm/s, and three a PSV > 180 cm/s. MDCT gave further anatomic information. Direct stenting was performed in 11 (84.6%) cases, whereas in 2 (15.4%) cases predilatation was required. In all cases postdilatation was performed. Technical and clinical success and safety were evaluated. Stent patency was evaluated during the 12-month follow-up. RESULTS: Technical success was achieved in all cases. In three patients a nonsignificant residual stenosis < 30% has been reported. No major complications during or after the procedure occurred. One patient (7.7%) showed a transitory bradycardia during angioplasty. One (7.7%) local bleeding at the puncture site treated conservatively occurred. All the neurological examinations performed 24 h and 30 days after the procedure were negative. No significant ISR was registered. In 2 patients, < 30% ISR was revealed at DUS performed after 6 months and confirmed at 12 months. In both patients CEUS and MDCT denied the presence of significant stenosis. CONCLUSIONS: Roadsaver stent seems to be durable. Further studies with longer-term outcome are necessary to confirm our results.

Vascular malformations are often found inside the orbit. Isolated venous malformations (frequently misnamed as cavernous hemangiomas) are the most frequent among these. However, also lymphatic and arteriovenous malformations can affect the orbit. The complex anatomy of the orbit and the fact that its content easily suffers from compartmental syndrome explain why treating orbital vascular malformations can be challenging and technically demanding. In this study, two institutions have retrospectively collected their cases, consisting in a total of 69 vascular malformations of the orbit. Each type of malformation has been evaluated separately in terms of diagnosis, indications for treatment, techniques and outcomes. Moreover, the authors have analyzed in detail venous malformations, identifying three different types, named orbital venous malformation (OVM) 1, 2 and 3. These behave differently from each other, and a prompt differential diagnosis is mandatory to pose correct indications, minimize risks and improve results. Overall, surgery was the technique of choice for OVM1, microcystic lymphatic malformations (LM) and arteriovenous malformations (AVM). A pure transnasal approach with mass removal and reconstruction of the medial wall with polyethylene sheets was chosen for OVM1 (intra- or extraconal) located in the medial or superomedial compartment. Sclerotherapy had a role in treating macrocystic LM and OVM3.

OBJECTIVE: To investigate CT morphologic and densitometric features and 18-FDG PET findings of surgically excised lung adenocarcinomas "mixed subtype" with predominant lepidic component, appearing as solid solitary pulmonary nodules (SPNs) on CT scan. MATERIALS AND METHODS: Approval for this study was given from each local institutional review board according to its retrospective nature. Nodules pathologically classified as lung adenocarcinoma mixed subtype with bronchioloalveolar otherwise lepidic predominant component, in three different Italian institutions (Napoli; Varese; Parma), were retrospectively selected. RESULTS: 22 patients were identified. The number of SPNs with smooth margins was significantly lower with respect to the number of SPNs with spiculated margins (p: 0.033), radiating spiculations (p: 0.019), and notch sign (p: 0.011). Mean contrast enhancement (CE) was 53.34 HU (min 5.5 HU, max 112 HU); considering 15 HU as cut-off value, CE was positive in 20/22 cases. No significant correlation was found between size and CE. Mean SUVmax was 2.21, ranging from 0.2 up to 7.5 units; considering 2.5 units as cut-off, SUVmax was positive in 7/22 cases. The number of SPNs with positive CE was significantly higher than the number of SPNs with positive SUVmax (p: 0.0005). CONCLUSION: CT generally helps in identifying solid SPN suspicious for malignancy but 18-FDG PET may result in false-negative evaluation; when 18-FDG PET findings of a solid SPN are negative even though CT morphology and CE suggest malignancy, radiologist should consider that lepidic component may be present inside the invasive tumor, despite the absence of ground glass.

AIM: To evaluate efficacy, safety and quality of life of the patients with renal angiomyolipomas (AMLs) associated with tuberous sclerosis complex (TSC) treated with percutaneous microwave ablation (MWA). MATERIALS AND METHODS: Nine patients (7 females and 2 males; mean age 27.6 years, range 23-34), with 10 renal AMLs with a mean size of 6.3 cm (range 4.5-8.5) were treated with image-guided percutaneous MWA. Indications for treatment were the risk of rupture/hemorrhage due to size greater than 4 cm and symptomatology; in one case, a previous hemorrhage was the indication for treatment. During follow-up, the volume of the ablated AMLs and its relationship with the relief of symptoms were registered. Technical and clinical success, safety, and quality of life (QOL) were evaluated in a mean follow-up of 9 months (range 3-12). RESULTS: Technical success was obtained in all cases. Clinical success was obtained in all cases; the volume of the ablated AMLs was not related with symptoms relief; all patients referred a significant improvement in their QOL, with a regularization of daily activities. There were no major procedural complications or delayed adverse events. A small self-limited post-procedural subcapsular hematoma was registered. Post-ablation syndrome was registered in 5 cases and was self-limited in all cases. CONCLUSIONS: Symptoms relief, lower risk of hemorrhage and a normalized QOL were obtained in all patients with a safe and mini-invasive procedure.

BACKGROUND: Coronary Artery Calcifications (CACs) are associated with coronary atherosclerosis and Cardiovascular (CV) events. In "non-cardiovascular" settings, CACs can be easily detected on chest Multi-Detector Computed Tomography (MDCT). Their evaluation may help to better stratify CV risk in the general population, especially for primary prevention. AIMS: We retrospectively evaluated the relationship between CAC distribution and CV risk, determined by Framingham Risk Score (FRS), in a cohort of patients who underwent chest MDCT performed for several clinical indications. METHOD: We retrospectively recruited 305 patients (194 men, 111 women; mean age 70.5 years) from 3 different Italian centres. Patients with coronary stent, pacemaker and/or CV devices were excluded from the study. Circumflex Artery (LCX), Left Main Coronary Artery (LMCA), left Anterior Descending artery (LAD) and right coronary artery (RCA) were analysed. RESULTS: From a total population of 305 patients, 119 (39%) had low FRS (<10%), 115 (38%) had intermediate FRS (10-20%), and 71 (23%) had high FRS (>20%). The study identified 842 CACs located in decreasing order as follows: RCA (34.5%), LAD (32.3%), LCX (28%) and LMCA (13%). Statistical two-step analysis subdivided patients into two clusters according to FRS (risk threshold = 12.38%): cluster I (mean 9.34) and cluster II (mean 15.09). A significant association between CAC distribution and cluster II was demonstrated. CACs were mostly detected in patients with intermediate FRS. All patients (100%) with the highest CV risk showed intermediate RCA and LMCA involvement. CONCLUSION: Radiologists can note the distribution of CACs on a chest MDCT and should mandatorily record them in their reports. Depending on CAC presence and location, these findings may have important clinical implications, mostly in asymptomatic patients with intermediate FRS. This information may reclassify a patients' CV risk and improve clinical management.

PURPOSE: To investigate the potential of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to discriminate responder from non-responder patients after preoperative chemoradiotherapy (pCRT) in locally advanced rectal cancer (LARC). MATERIALS AND METHODS: One hundred and fifty-eight consecutive patients were enrolled in this prospective study. We compared morphological MRI (mMRI) using T2-weighted images about tumor presence and invasiveness, and functional DCE-MRI using time-intensity curve (TIC) visual inspection (qMRI), classifying TIC shape into three types: type 1, persistent enhancement; type 2, high enhancement with plateau; type 3, high enhancement with wash-out. Clinical TNM was obtained before and after CRT by radiological consensus of two expert radiologists. Pathological tumor-nodes-metastasis classification and tumor regression grade (TRG) were confirmed as the golden standard. Non-parametric test, sensitivity, specificity, and positive and negative predictive values were calculated. RESULTS: Ninety-eight patients (62%) were classified as responders (TRG ≤ 2), while 60 (38%) were classified as non-responders. Sensitivity, specificity, and accuracy were 52, 78, and 62% for mMRI, and 81, 85, and 82% for qMRI, respectively. CONCLUSIONS: TIC visual inspection may be one of the potential biomarkers over morphological analysis using DCE-MRI data to assess pathological response after pCRT in LARC.

This review focuses upon interactions and potential therapeutic targets in the 'vicious cycle' between hypoxia and neoangiogenesis following treatment of hepatocellular carcinoma with transarterial loco-regional therapies. Biomarkers correlated with angiogenesis have been studied by many authors as prognostic determinants following transarterial intrahepatic therapy. According to these results future therapies directed toward specific factors related to angiogenesis could play a significant role in preventing local tumor recurrence and remote metastasis.

BACKGROUND: Thyroid nodules are very common in general population. Even if benign, they may require a treatment in case of symptoms or cosmetic concerns. In the last years, minimally invasive treatments alternative to surgery have been developed, in particular ultrasound (US) guided radiofrequency ablation (RFA). METHODS: Twenty-four patients (9 males; 15 females; mean age 57.9 years) were treated and divided in two groups (A and B) according to the RFA needle used (18 gauge needle, AMICA; 17 gauge needle, COVIDIEN). Nodules and patients characteristics, together with procedural data were registered pre-treatment and at 1-month follow-up. US visibility of the needle, volume of the nodules, symptoms and cosmetic concerns, complications were registered. RESULTS: Visibility of the needle was not significantly different in the two groups (P=0.0787). At 1 month the mean volume of the nodules dropped from 37.1 to 25 mL in group A and from 23.2 to 15.4 mL in group B; shrinkage rate (36.9% and 39.5%, respectively) was not significantly different (P=0.3137). Symptoms decreased from 3.1 to 1.4 in group A and from 4 to 1.6 in group B: no significant differences in reductions were observed (P=0.3305). Cosmetic score decreased from 3.7 to 3.4 in group A and from 3.9 to 3.6 in group B: no significant differences in reductions were observed (P=0.96). Total complication rate (18.2% in group A vs. 23.1% in group B) did not showed significant differences (P=0.5049). CONCLUSIONS: The two systems used in our study resulted equivalent in terms of US needle visibility, efficacy, symptom/cosmetic relief, safety. More patients and a longer follow-up are necessary to confirm our results.
RESUMEN
Prostatectomy via open surgery or transurethral resection of the prostate (TURP) is the standard treatment for benign prostatic hyperplasia (BPH). Several patients present contraindication for standard approach, individuals older than 60 years with urinary tract infection, strictures, post-operative pain, incontinence or urinary retention, sexual dysfunction, and blood loss are not good candidates for surgery. Prostatic artery embolization (PAE) is emerging as a viable method for patients unsuitable for surgery. In this article, we report results about technical and clinical success and safety of the procedure to define the current status.
