Abstract
BACKGROUND Severe secondary hyperparathyroidism (SHPT) is associated with mortality in end stage kidney disease (ESKD). Parathyroidectomy (PTX) becomes necessary when medical therapy fails, thus highlighting the interest to compare biochemical and clinical outcomes of patients receiving either medical treatment or surgery. METHODS We aimed to compare overall survival and biochemical control of hemodialysis patients with severe hyperparathyroidism, treated by surgery or medical therapy followed-up for 36 months. Inclusion criteria were age older than 18 years, renal failure requiring dialysis treatment (hemodialysis or peritoneal dialysis) and ability to sign the consent form. A control group of 418 patients treated in the same centers, who did not undergo parathyroidectomy was selected after matching for age, sex, and dialysis vintage. RESULTS From 82 Dialysis units in Italy, we prospectively collected data of 257 prevalent patients who underwent parathyroidectomy (age 58.2 ± 12.8 years; M/F: 44%/56%, dialysis vintage: 15.5 ± 8.4 years) and of 418 control patients who did not undergo parathyroidectomy (age 60.3 ± 14.4 years; M/F 44%/56%; dialysis vintage 11.2 ± 7.6 y). The survival rate was higher in the group that underwent parathyroidectomy (Kaplan-Meier log rank test = 0.002). Univariable analysis (HR 0.556, CI: 0.387-0.800, p = 0.002) and multivariable analysis (HR 0.671, CI:0.465-0.970, p = 0.034), identified parathyroidectomy as a protective factor of overall survival. The prevalence of patients at KDOQI targets for PTH was lower in patients who underwent parathyroidectomy compared to controls (PTX vs non-PTX: PTH < 150 pg/ml: 59% vs 21%, p = 0.001; PTH at target: 18% vs 37% p = 0.001; PTH > 300 pg/ml 23% vs 42% p = 0.001). The control group received more intensive medical treatment with higher prevalence of vitamin D (65% vs 41%, p = 0.0001), calcimimetics (34% vs 14%, p = 0.0001) and phosphate binders (77% vs 66%, p = 0.002). CONCLUSIONS Our data suggest that parathyroidectomy is associated with survival rate at 36 months, independently of biochemical control. Lower exposure to high PTH levels could represent an advantage in the long term.

Abstract
In 2011, a first peritoneal dialysis audit was held in the Lazio region to analyze the problems hindering the spread of this method and to improve the quality of care through the sharing of best practices across Centers. A scientific board was therefore set up, representing all the Centers offering PD, in order to assess clinical effectiveness using KPIs (Key Performance Indicators) and to quantify the objectives to be achieved. The analysis made it possible to identify the main problems and take action, all the while monitoring progress through KPIs. A second audit was carried out in 2017 and the collected data was analyzed and compared with the findings of the previous study. Overall, data showed an increase in prevalence, although the incidence showed a slight decrease. Indicators on the change of dialysis treatment, the dropout from domiciliary treatment and the incidence of late referral appeared stable over time. A slight improvement was observed in clinical data on peritonitis and on the length of hospitalization. All participants in the audit declared that sharing and discussing clinical practices had been really useful. In addition, through the drafting of practical documents (guides for patients, guidance on informed consent, protocols of clinical follow-up), a number of tools have been provided to ensure a uniformly high level of care across the different regional Centers.

Abstract
PURPOSE Rhabdomyosarcoma (RMS), the most common soft-tissue sarcoma in childhood, rarely affects adults, preferring male. RMS expresses the receptor for androgen (AR) and responds to androgen; however, the molecular action of androgens on RMS is unknown. METHODS Herein, testosterone (T) effects were tested in embryonal (ERMS) and alveolar (ARMS) RMS cell lines, by performing luciferase reporter assay, RT-PCR, and western blotting experiments. RNA interference experiments or bicalutamide treatment was performed to assess the specific role of AR. Radiation treatment was delivered to characterise the effects of T treatment on RMS intrinsic radioresistance. RESULTS Our study showed that RMS cells respond to sub-physiological levels of T stimulation, finally promoting AR-dependent genomic and non-genomic effects, such as the transcriptional regulation of several oncogenes, the phosphorylation-mediated post-transductional modifications of AR and the activation of ERK, p38 and AKT signal transduction pathway mediators that, by physically complexing or not with AR, participate in regulating its transcriptional activity and the expression of T-targeted genes. T chronic daily treatment, performed as for the hormone circadian rhythm, did not significantly affect RMS cell growth, but improved RMS clonogenic and radioresistant potential and increased AR mRNA both in ERMS and ARMS. AR protein accumulation was evident in ERMS, this further developing an intrinsic T-independent AR activity. CONCLUSIONS Our results suggest that androgens sustain and improve RMS transformed and radioresistant phenotype, and therefore, their therapeutic application should be avoided in RMS post puberal patients.

Abstract
Background The original peritoneal equilibration test (PET) was used to classify peritoneal dialysis (PD) patients using a 2.27% glucose solution. It has since been suggested that a 3.86% glucose solution be used because this provides better information about ultrafiltration (UF) capacity and the sodium (Na) sieving of the peritoneal membrane. Objective The aim of this study was to determine reference values for a PET using a 3.86% glucose solution (PET-3.86%). Methods We evaluated the PET-3.86% in a large population of incident PD patients attending 27 Italian dialysis centers. Results We evaluated the results of 758 PET-3.86% in 758 incident PD patients (1 test per patient). The mean duration of PD was 5 ± 3 months. The ratio of the concentrations of creatinine in dialysate/plasma (D/PCreat) was 0.73 ± 0.1 (median 0.74). The ratio between the concentrations of glucose at the end/beginning of the test (D/D0) was 0.25 ± 0.08 (median 0.24). Ultrafiltration uncorrected and corrected for bag overfill was respectively 776 ± 295 mL (median 781 mL) and 675 ± 308 mL (median 689 mL). Sodium sieving was 8.4 ± 3.8 mmol/L (median 8.0 mmol/L). Conclusion The results of the study provide PET-3.86% reference values for the beginning of PD that can be used to classify PD patients into transport classes and monitor them over time.

Abstract
The diffusion of peritoneal methodology can not be something out of the real organizational context and the regional directive can not be the only means to encourage the diffusion. There is the need to provide effective and sustainable levels of assistance through a clinical scientific support and sharing of best-practises. On one side, the aim is to provide an aid by the centers with great expertise in the methodology, recognized as reference points; on the other side, to establish the shared K.P.I.s (Key Performance Index), to asses the clinical effectiveness and measure the objectives to be achieved, through a modality of valuation to establish the real applicability. For this purpose, a scientific board was founded, composed by the heads of UU.OO, that provide the peritoneal dialysis, to determine which aspects to investigate and identify factors of supply improvement. The selected method was the clinical audit. The analysis of the 2011 data has allowed us to capture the situation of the peritoneal dialysis in the Lazio Region. The formative procedure has enabled the centers to share and standardize protocols and therapeutic procedures, identify the strengths of peritoneal dialysis in the Lazio Region and define the KPIs through whose compare and monitor the centers over time. The conclusive analysis of the audit has enabled to identify a series of activities to be undertaken together in order to improve the situation of the peritoneal dialysis in the Lazio Region. In the following years, surveys will be carried out to verify the KPIs trend.

Abstract
BACKGROUND Psychological disorders are often associated with diseases of the upper digestive tract. Although emotions can influence gastrointestinal function in healthy individuals, psychological setting in upper gastrointestinal patients are unclear. We evaluate the psychological alterations prevalence in outpatients submitted to upper endoscopy. MATERIALS AND METHODS A total of 130 patients (50 males and 80 females; mean age 54±17 years) submitted to upper gastrointestinal endoscopy, were enrolled over the period May 2009 - September 2010. Subjects were asked to complete questionnaires before endoscopic examination. Alexithymia, anxiety, depression and coping style were assessed using the Toronto Alexithymia Scale, Spielberger Trait Anxiety Inventory, Beck Depression Inventory and Coping Inventory for Stressful Situations, respectively. RESULTS Coping impairment, Alexithymia, Anxiety and Depression were found respectively in 80.3%, 25.4%, 24.6% and 17.2%, often in association. Task-oriented, emotion-oriented and avoidance-oriented alterations were found in 41.8%, 40% and 30.6%, respectively. No correlations were demonstrated between diagnosis of upper gastrointestinal disease and psychometric results. CONCLUSIONS In our study, a high prevalence of psychometric alterations in gastrointestinal outpatients was unconnected with endoscopic findings, especially considering coping style alterations. This aspect should be taken into account in patients management and a long-term follow-up should clarify a possible role of these factors in patients prognosis and compliance.

Abstract
BACKGROUND Thyroidectomy performed by an experienced surgeon is associated with a low incidence of recurrent laryngeal nerve injury and permanent hypoparathyroidism. During reoperative thyroid surgery there is a higher technical risk because detection and preservation of the recurrent laryngeal nerves and parathyroid glands are more difficult than in the primary surgery. AIM Our retrospective cohort study was to assess short- and long-term complications associated with reoperative thyroid surgery in order to suggest a technical approach to lower the morbidity rate. MATERIALS AND METHODS From January 2005 to September 2013, 745 patients underwent surgery for thyroid disease. Before surgery all patients underwent clinical examination, laboratory blood tests, hormonal assays, neck ultrasound, chest radiography and indirect laryngoscopy. Patients were followed up at 1, 3, 6 months and then annually after operation with hormonal assays, blood tests and neck ultrasound. RESULTS Eighty (10.7%) out of 745 patients (mean-age= 52.5 years; age-range 18-80) underwent reoperative surgery for recurrent thyroid disease. The primary treatments were enucleoresection (11.2%), thyroid lobectomy(56,3%), thyroid lobectomy with isthmectomy(10%) and subtotal thyroidectomy (22,5%). In the reoperative surgery group (Group Re) the transient RLN complications were 1.3% compared to 0.2% in the primary surgery group (Group P) (p= 0.51). The incidence of temporary hypocalcemia was 45% in the reoperative surgery group vs. 42.7% in the primary surgery group (p=0.72). CONCLUSIONS Reoperative surgery should be reserved to experienced surgeons. However, even in this case, when surgical maneuvers reserved for primary surgery are applied, then this surgery is associated with a low complications rate.

Abstract
Superficial vein thrombosis is characterized by clotting of superficial veins (ie, following direct trauma) with minimal inflammatory components. Superficial thrombophlebitis is a minimally thrombotic process of superficial veins associated with inflammatory changes and/or infection. Treatments generally include analgesics, elastic compression, anti-inflammatory agents, exercise and ambulation, and, in some cases, local or systemic anticoagulants. It is better to avoid bed rest and reduced mobility. Topical analgesia with nonsteroidal, anti-inflammatory creams applied locally to the superficial vein thrombosis/superficial thrombophlebitis area controls symptoms. Hirudoid cream (heparinoid) shortens the duration of signs/symptoms. Locally acting anticoagulants/antithrombotics (Viatromb®, Lipohep ®, spray Na-heparin) have positive effects on pain and on the reduction in thrombus size. Intravenous catheters should be changed every 24 to 48 hours (depending on venous flow and clinical parameters) to prevent superficial vein thrombosis/superficial thrombophlebitis and removed in case of events. Low molecular weight heparin prophylaxis and nitroglycerin patches distal to peripheral lines may reduce the incidence of superficial vein thrombosis/superficial thrombophlebitis in patients with vein catheters. In case of superficial vein thrombosis/superficial thrombophlebitis, vein lines should be removed. In neoplastic diseases and hematological disorders, anticoagulants may be necessary. Exercise reduces pain and the possibility of deep vein thrombosis. Only in cases in which pain is very severe is bed rest necessary. Deep vein thrombosis prophylaxis should be established in patients with reduced mobility. Antibiotics usually do not have a place in superficial vein thrombosis/superficial thrombophlebitis unless there are documented infections. Prevention of superficial vein thrombosis should be considered on the basis of patient's history and clinical evaluation.

Abstract
The three members of the Aurora kinase family, Aurora-A, -B and -C, regulate several aspects of the mitotic process, and their aberrant expression and/or function causes mitotic abnormalities leading either to cell death or aneuploidy. They are found overexpressed in several human malignancies, including the papillary thyroid carcinoma (PTC). In the present study, we sought to establish whether Aurora kinase inhibition could be of any therapeutic value in the treatment of aggressive forms of PTC, enduring to radioactive iodide (RAI) ablation. To this end, the effects of selective inhibitors of Aurora-A (MLN8237) and Aurora-B (AZD1152) were analyzed on 3 human PTC cell lines expressing either wild-type (K1 and TPC1) or mutant p53 (BCPAP). The two inhibitors were capable of reducing cell proliferation in a time- and dose-dependent manner, with IC₅₀ comprised between 65.4 and 114.9 nM for MLN8237, and between 26.6 and 484.6 nM for AZD1152. Immunofluorescence experiments confirmed that AZD1152 inhibited Aurora-B phosphorylation of histone H3 on Ser10, however, it did not affect Aurora-A autophosphorylation. MLN8237 inhibited Aurora-A autophosphorylation as expected, but at concentrations required to achieve the maximum antiproliferative effects it also abolished H3 (Ser10) phosphorylation. Time-lapse videomicroscopy evidenced that both inhibitors prevented the completion of cytokinesis, and cytofluorimetric analysis showed accumulation of cells in G2/M phase and/or polyploidy. Apoptosis was induced in all the cells by both inhibitors independently from the p53 status. In conclusion, in the present preclinical study MLN8237 and AZD1152 have emerged as promising drug candidates for RAI-insensitive PTC.

Abstract
BACKGROUND We sought to document the time required by health care professionals to administer erythropoiesis-stimulating agents (ESAs) and continuous erythropoiesis receptor activator (C.E.R.A.) in the management of renal anaemia. METHODS A Time and Motion study was conducted in 13 centres in Italy. The time spent on preparation, distribution, and injection for both ESA and C.E.R.A. groups was measured. A multilevel model was run to account for the centre-clustering effect. RESULTS The average number of ESA injections/patient/year was 89. The average uptake of C.E.R.A. was 26%. The average time per session was 1.54 min for ESA (95% CI 1.21-1.86) vs. 1.64 min for C.E.R.A. (95% CI 1.31-1.97). Estimated time/patient/year was 137 min for ESA and 20 min for C.E.R.A. Assuming a 100% uptake of C.E.R.A., annual time savings/centre would be 84% (194 h). CONCLUSIONS Substantial annual time savings on frequent anaemia management-related tasks were found when a switchover was made from ESAs to C.E.R.A.

Abstract
Components of the death receptor-mediated pathways like caspase-8 have been identified in complexes at intracellular membranes to spatially restrict the processing of local targets. In this study, we report that the long isoform of the cellular FLICE-inhibitory protein (c-FLIP(L)), a well-known inhibitor of the extrinsic cell death initiator caspase-8, localizes at the endoplasmic reticulum (ER) and mitochondria-associated membranes (MAMs). ER morphology was disrupted and ER Ca(2+)-release as well as ER-mitochondria tethering was decreased in c-FLIP(-/-) mouse embryonic fibroblasts (MEFs). Mechanistically, c-FLIP ablation resulted in enhanced basal caspase-8 activation and in caspase-mediated processing of the ER-shaping protein reticulon-4 (RTN4) that was corrected by re-introduction of c-FLIP(L) and caspase inhibition, resulting in the recovery of a normal ER morphology and ER-mitochondria juxtaposition. Thus, the caspase-8 inhibitor c-FLIP(L) emerges as a component of the MAMs signaling platforms, where caspases appear to regulate ER morphology and ER-mitochondria crosstalk by impinging on ER-shaping proteins like the RTN4.

Abstract
Elastofibroma Dorsi (EFD) is a rare pseudo-tumor characterized by the overgrowth of elastic fibers mixed to adipose and connective tissues typically growing in the subscapular region. This can be bilateral but only rarely synchronous affecting different anatomical sites at the same time. Hereby we present a case of a 42-year-old male patient found with three different metachronous elastofibromas: bilateral EFD and a further third localization by the right elbow. The two EFs in the subscapular region were resected. After surgery pain reoccurred on the right side. This required the implantation of a spinal electro-stimulator. The elbow lesion was not excised as it was asymptomatic.

Abstract
AIM Recurrent vulvovaginal candidosis (RVVC) can be a long-lasting disease; some patients refuse one of the most used treatment based on the assumption of oral fluconazole and resort to self-medication, risking poor control of symptoms and the development of local side effects. The aim of the study is to compare underwear made of Dermasilk®, a pure fibroin fabric bonded with a permanent antimicrobial protection, with cotton placebo briefs to see whether it would be a useful tool in the management of RVVC in patients not receiving oral or topical antimycotic treatment. METHODS A double-blind, randomized study was carried out on 30 women who had a long-term history of RVVC with mild to moderate symptoms. The patients were randomly divided into two groups and instructed to use either white cotton placebo briefs (CT group) or Dermasilk® briefs (DS group) for 6 months. RESULTS All vulvovaginal symptoms and signs showed a statistically significant improvement in the DS group compared with the CT group (P<0.001) at the follow-up visits after 3 and 6 months. The number of flares of vulvovaginal symptoms was significantly lower in the DS group compared to the CT group (24 episodes versus 68 episodes during the 6-month study, P<0.001). CONCLUSION In the absence of both topical and oral antimycotics, Dermasilk® briefs appear to be a useful tool, in reducing the signs and symptoms and the episodes of vulvovaginal discomfort in patients suffering from RVVC.

Abstract
BACKGROUND Patients on dialysis may have abnormal serum levels of Ca, P and parathyroid hormone, with related bone diseases. This population has an increased risk of death, with cardiovascular calcification (CC) a contributing factor. Patients on peritoneal dialysis appear to be at increased risk of hyperlipidemia, a contributing factor to atherosclerotic plaque formation. Although several studies have described the presence and progression of CC in hemodialysis populations, there are fewer data in patients on peritoneal dialysis. STUDY DESIGN The Renal Osteodystrophy and Calcifications: Key factors in Peritoneal Dialysis (ROCK-PD) study was a 36-month, prospective observational study conducted in Italy. The study examined the presence and progression of CC in two cardiac valves and five arterial sites. The potential associations of serum Ca and P with mortality and cardiovascular morbidity, demographic, clinical and blood chemistry variables was investigated. RESULTS CC was present in 77% of patients at baseline (N=369) and in 90% of patients by study end (N=145), progressing in 73% of patients. There were 42 deaths (11%). Analyses showed a marked correlation between baseline P levels and the presence of left ventricular hypertrophy. However, there were no consistent correlations between serum Ca or P with mortality or morbidity. CONCLUSIONS CC was common in peritoneal dialysis patients and progressed in a majority of patients.
