Abstract
BACKGROUND: Epidural infusion of levobupivacaine and ropivacaine provides adequate postoperative pain management by minimizing side effects related to IV opioids and improving patient outcome. The safety profile of different drugs can be better estimated by comparing their pharmacokinetic profiles than by considering their objective side effects. Because levobupivacaine and ropivacaine have different pharmacokinetic properties, our aim was to investigate whether there is a difference in the pharmacokinetic variability of the 2 drugs in a homogeneous population undergoing continuous epidural infusion. This double-blind, multicenter, randomized, controlled trial study was designed to compare the pharmacokinetics of continuous thoracic epidural infusion of levobupivacaine 0.125% or ropivacaine 0.2% for postoperative pain management in adult patients who had undergone major abdominal, urological, or gynecological surgery. This study is focused on the evaluation of the coefficient of variation (CV) to assess the equivalence in the systemic exposure and interindividual variability between levobupivacaine and ropivacaine and, therefore, the possible differences in the predictability of the plasmatic concentrations of the 2 drugs during thoracic epidural infusion. METHODS: One hundred eighty-one adults undergoing major abdominal surgery were enrolled in the study. Patients were randomized to receive an epidural infusion of levobupivacaine 0.125% + sufentanil 0.75 μg/mL or of ropivacaine 0.2% + sufentanil 0.75 μg/mL at 5 mL/h for 48 hours. The primary end point of this study was to analyze the variability of plasma concentration of levobupivacaine and ropivacaine via an area under the curve within a range of 15% of the CV during 48 hours of continuous epidural infusion. The CV shows how the concentration values of local anesthetics are scattered around the median concentration value, thus indicating the extent to which plasma concentration is predictable during infusion. Secondary end points were to assess the pharmacologic profile of the local anesthetics used in the study, including an analysis of mean peak plasma concentrations, and also to assess plasma clearance, side effects, pain intensity (measured with a verbal numeric ranging score, i.e., static Numeric Rating Scale [NRS] and dynamic NRS]), and the need for rescue doses. RESULTS: The comparison between the 2 CVs showed no statistical difference: the difference between area under the curve was within the range of 15%. The CV was 0.54 for levobupivacaine and 0.51 for ropivacaine (P = 0.725). The plasma concentrations of ropivacaine approached the Cmax significantly faster than those of levobupivacaine. Clearance of ropivacaine decreases with increasing patient age. There were no significant differences in NRS, dynamic NRS scores, the number of rescue doses, or in side effects between groups. CONCLUSIONS: Considering the CV, the interindividual variability of plasma concentration for levobupivacaine and ropivacaine is equivalent after thoracic epidural infusion in adults. We found a reduction in clearance of ropivacaine depending on patient age, but this finding could be the result of some limitations of our study. The steady-state concentration was not reached during the 48-hour infusion and the behavior of plasma concentrations of ropivacaine and levobupivacaine during continuous infusions lasting more than 48 hours remains to be investigated, because they could reach toxic levels. Finally, no differences in the clinical efficacy or in the incidence of adverse effects between groups were found for either local anesthetic. Published ahead of print May 14, 2015

Abstract
Background Noonan syndrome (NS) is an autosomal dominant disorder characterized by specific features including short stature, distinctive facial dysmorphic features, congenital heart defects, hypertrophic cardiomyopathy, skeletal anomalies and webbing of the neck. Molecular screening has shown that the majority of individuals with NS have a mutation in the PTPN11 gene. Noonan syndrome children may show an impaired growth hormone (GH)/insulin-like growth factor axis. Moreover, recombinant human GH (rhGH) has been shown to improve growth rate in patients with NS, although data are still limited. Methods In the present study, we assessed growth response following GH therapy (0.25 mg/Kg/week) in 5 (2 M and 3 F) GH-deficient NS patients (NSGHD, mean age 8.5 years) and in 5 (2 M and 3 F) idiopathic GH deficient (IGHD, mean age 8.6 years) patients. We also evaluated the safety of rhGH therapy in NS patients with GHD. Results At the beginning of GH treatment, height and growth rate were statistically lower in NSGHD children than in IGHD ones. During the first three years of rhGH therapy, NSGHD patients showed a slight improvement in height (from −2.71 SDS to −2.44 SDS) and growth rate (from −2.42 SDS to −0.23 SDS), although the values were always significantly lower than in IGHD children. After five years of rhGH treatment, height gain was higher in IGHD children (mean 28.3 cm) than in NSGHD patients (mean 23.6 cm). During the first five years of rhGH therapy, regular cardiological and haematological check-ups were performed, leading to the conclusion that rhGH therapy was safe. Conclusions In conclusion, pre-pubertal NS children with GHD slightly increased their height and growth rate during the first years of GH therapy, although the response to rhGH treatment was significantly lower than IGHD children. Furthermore, the therapy appeared to be safe since no severe adverse effects were reported, at least during the first five years. However, a close follow-up of these patients is mandatory, especially to monitor cardiac function.

Abstract
BACKGROUND Congenital Muscular Torticollis (CMT) is the most common form of torticollis in infants; on clinical presentation it is classified into 3 types: 1) postural torticollis, with postural deformity only in the neck; 2) muscular torticollis, where neck deformity is associated with muscle tightness and restricted passive range of motion (ROM); and 3) sternomastoid tumor or pseudotumor, with a fibrotic, sternocleido-mastoid muscle mass and passive ROM limitations. AIM The aim of this study was to evaluate the physical therapy outcome of infants with CMT treated either by parents using a home exercise program, or by a physical therapist. DESIGN Longitudinal study. SETTING Outpatients with CMT at our Department of Physical Medicine and Rehabilitation. POPULATION Fifty consecutive newborns with CMT, referred by the primary pediatrician: METHODS In our study, 50 infants with CMT were evaluated and treated either by a physical therapist or by parents using a home program. RESULTS Sixteen females (32%) and 34 males (68%), aged 10.2 weeks (SD 6.66); 23 of the infants (46%) presented with more severe articular limitations than the others (P=0.002) and were therefore prescribed outpatient treatment by a physical therapist; the remaining 27 less severe cases (54%) were prescribed a home therapy program. 49 infants achieved full resolution after an average of 81.06 days (SD 64.05) of rehabilitation treatment. The group of patients who were treated at home achieved resolution more quickly (72.8 vs. 91.1 days), although statistical significance was not reached. CONCLUSIONS Infants with CMT who were treated early, either at home or in the outpatient clinic, completely recovered normal neck movement in a short time. It is important not to discharge patients until they have achieved full resolution of CMT symptoms to exclude the minimal risk of relapse. CLINICAL REHABILITATION IMPACT This study demonstrates the importance of early treatment in cases of congenital muscular torticollis.

Abstract
The association between vulvodynia and interstitial cystitis/bladder pain syndrome (IC/BPS), a chronic, debilitating disease of unknown etiology, may involve sex hormone-dependent mechanisms regulating vulvo-vaginal health. We aimed to prospectively investigate the effects of 12 weeks of local estrogen therapy (LET) on urinary/bladder and sexual symptoms in premenopausal women with IC/BPS. Thirty-four women (mean age: 36.1 ± 8.4) diagnosed with IC/BPS were treated vulvo-vaginally three-times/week with estriol 0.5 mg cream and tested by validated questionnaires (ICSI/ICPI, pain urgency frequency [PUF], female sexual function index [FSFI]) and by cotton swab testing, vaginal health index (VHI) and maturation index (MI) before and after treatment. Vulvodynia was present in 94.1% of IC/BPS women. A significant positive effect of LET was evident on urinary and sexual function (p < 0.001, for both) following 12 weeks, as well as an improvement of the VHI (p < 0.001) and the MI (p < 0.04). The results of this open study indicate that 12 weeks of local estriol cream at vaginal and vestibular level may ameliorate urinary/bladder pain symptoms, as well as may improve domains of sexual function. The association between vulvar pain and bladder pain could, therefore, be related to a vaginal environment carrying signs of hypoestrogenism, but further studies are needed to clarify this issue.

Abstract
PURPOSE To evaluate and compare clinical, functional and quality of life (QOL) outcomes after two types of surgical approach for single level cervical disc herniation: anterior cervical discectomy andfusion (ACDF) with cage and cervical artificial disc replacement (C-ADR). METHOD 119 patients with cervical disc herniation underwent surgery from January 2007 to December 2010; 55 patients were included in the study (27 ACDF, 28 C-ADR). We performed: a pre and postoperative clinical evaluation of cervicobrachial pain, motor and sensory deficit in the upper limbs; a functional and QOL evaluation with self assessment scales (VAS, NPNQ, SF-36); a postoperative instrumental evaluation of cervical ROM and pain. Mean follow-up period was 24 months. RESULTS After surgery both groups showed clinical, functional and QOL improvement. No pre and postoperative differences were found between the groups. The postoperative instrumental evaluation showed a globally reduced cervical ROM and a decreased pain threshold in comparison with normal values in both groups. CONCLUSION Our results demonstrate the clinical equivalence of the two surgical techniques and the satisfaction of the two groups of patients two years after surgery. Although functional changes persist after surgery they do not affect quality of life.

Abstract
OBJECTIVE To evaluate whether rituximab at a low dose of 250 mg/m(2) × 2 may be as effective as at higher dosages, most commonly 375 mg/m(2)×4, used in previous studies on the treatment of patients with refractory mixed cryoglobulinemia (MC) vasculitis associated with hepatitis C virus (HCV) infection. METHODS We conducted a phase 2, single-arm two-stage trial (EUDRACT n. 2008-000086-38) of low-dose rituximab in 52 patients with HCV-associated MC who were ineligible/intolerant or non-responder to antiviral therapy. The primary outcomes were response of vasculitis evaluated by the Birmingham Vasculitis Activity Score (BVAS) at months 3, 6 and 12, rate of relapses and time to relapse, and rate of adverse events. Our data were compared with those reported in 19 published studies selected among 291 reviewed in a literature search. RESULTS The cumulative response rate (complete and partial) at month 3 was 81% in our patients, and 86% in 208 patients from studies using high-dose rituximab. The relapse rate and median time to relapse were, respectively, 41% and 6 months in our study, and 32% and 7 months in high-dose studies. Treatment-related adverse events were 11.5% in our study and 19.9% in high-dose studies. None of these differences was statistically significant. CONCLUSION Rituximab at a low dosage of 250 mg/m(2) × 2 is as effective as at higher dosages for treating MC vasculitis. This low-dose regimen may improve the cost/benefit profile of rituximab therapy for MC.

Abstract
The decisional balance inventory (DBI) test is a valuable tool to assess motivation to change; we consider its application in enhancing motivation of losing weight. Our aim is the translation, cultural adaption and validation in Italian of this test originally designed and drafted in English. The questionnaire has been translated according to an <em>English</em> → <em>Italian</em> → <em>Italian</em> → <em>English</em> algorithm with reconciliation of the differences. Pilot study and retests were performed on 47 cases [body mass index (BMI) ≥30 kg/m<sup>2</sup>] and 15 controls (BMI value between 18.5 and 25 kg/m<sup>2</sup>). The internal consistency of the Italian version of DBI test, was satisfied (Cronbach α 0.87 on patients); test-retest shows a good concordance in pilot [Lin’s concordance correlation coefficient (CCC) 0.79; 95% confidence interval (CI) 0.68-0.90] and in patient sample (Lin’s CCC 0.83; 95% CI: 0.67 0.99).Our study demonstrated the trans-cultural adaptation and validation of DBI test in Italian.

Abstract
PURPOSE Peptide receptor radionuclide therapy (PRRT) for the treatment of neuroendocrine tumours (NET) has been explored for almost two decades, but there are still few trials that have exclusively investigated well-differentiated and moderately differentiated NET arising from the respiratory tree. Thus, the aim of this study was to explore the outcome in patients affected by bronchopulmonary carcinoid (BPC) following PRRT. METHODS We retrospectively analysed 114 patients with advanced stage BPC consecutively treated with PRRT at the European Institute of Oncology, Milan, from 1997 to 2012 and followed until October 2014. The objective responses, overall survival (OS) and progression-free survival (PFS) were rated, and three different PRRT protocols ((90)Y-DOTATOC vs. (177)Lu-DOTATATE vs. (90)Y-DOTATOC + (177)Lu-DOTATATE) were compared with regard to their efficacy and tolerability. RESULTS The median OS (evaluated in 94 of the 114 patients) was 58.8 months. The median PFS was 28.0 months. The (177)Lu-DOTATATE protocol resulted in the highest 5-year OS (61.4%). Morphological responses (partial responses + minor responses) were obtained in 26.5% of the cohort and were associated with longer OS and PFS. The (90)Y-DOTATOC + (177)Lu-DOTATATE protocol provided the highest response rate (38.1%). Adverse events were mild in the majority of patients. However, haematological toxicity negatively affected survival. No severe (grade 3/4) serum creatinine increase was observed. Patients treated with (90)Y-DOTATOC alone more frequently showed a mild/moderate decrease in renal function. In patients treated with chemotherapy before PRRT had a shorter OS and PFS, and a higher risk of developing nephrotoxicity. CONCLUSION In a large cohort of patients with advanced BPC treated in a "real-world" scenario and followed up for a median of 45.1 months (range 2-191 months), PRRT proved to be promising in prolonging survival and delaying disease progression. Despite the potential selection biases, considering the risk-benefit ratio, (177)Lu-DOTATATE monotherapy seems the best option for PRRT. Our results indicate that the use of PRRT in earlier stages of the disease could provide a more favorable outcome.

Abstract
BACKGROUND & AIMS The study aimed to evaluate the tissue expression of molecules involved in intracellular signalling pathways as predictors of response to sorafenib in advanced hepatocellular carcinoma (HCC). METHODS We considered 77 patients enrolled into three prospective trials of sorafenib treatment for whom pretreatment tumour tissue was available. The tissue expression of β-catenin, glutamine synthetase (GS), phosphorylated extracellular signal regulated kinase (pERK), phosphorylated v-akt murine thymoma viral oncogene homolog (pAKT) and vascular endothelial growth factor receptor-2 (VEGFR-2) was analysed by immunostaining. Stains were scored semiquantitatively and compared with a reference group of 56 untreated HCCs. RESULTS Overall, the expression of antigens was comparable between treated and untreated patients. Shorter progression-free survival (PFS) and overall survival (OS) were associated with increased pERK staining (≥ 2+ scores) (PFS: 75th percentile 4.4 vs 8.4 months; P = 0.01; OS: 75th percentile 7.0 vs 15.0 months; P = 0.005) and VEGFR-2 staining (≥ 2+ scores) (PFS: 75th percentile 3.8 vs 7.0 months; P = 0.039; OS: 75th percentile 6.3 vs 15.0 months; P = 0.004). At multivariate analysis, both pERK and VEGFR-2 staining maintained an independent effect on OS (HR 2.09; 95% CI, 1.13-3.86, P = 0.019 and HR 2.28; 95% CI, 1.13-4.61, P = 0.021 respectively). No effect was observed for the other tested biomarkers. CONCLUSIONS Elevated tissue expression of pERK and VEGFR-2 was predictive of poor outcome in advanced HCC treated with sorafenib.

Abstract
Autoimmune rheumatic diseases in pregnancies are associated with increased adverse obstetric outcomes. We compared maternal soluble human leucocyte antigen-G (sHLA-G) blood levels in subjects with a rheumatic disease preexisting pregnancy and unaffected controls. Third-trimester blood maternal sHLA-G concentrations were significantly higher in subjects with rheumatic diseases than in controls (mean 93.1ng/ml [SD 42.1] vs 58.1ng/ml [SD 96.3], p=0.003). Cord blood sHLA-G concentrations were significantly higher in rheumatic disease than in those born to control mothers (median 41.2ng/ml [IQR: 3.3-44.0] vs 17.9ng/ml [IQR: 17.2-88.1], p=0.007). A strict positive correlation (r=0.88, p<0.001) was found between the maternal and fetal titers of ANA autoantibodies as well as between maternal and fetal sHLAG circulating levels (r=0.58 and r=0.67, respectively, for controls and cases, p<0.001). Maternal s-HLA-G blood concentrations were significantly higher in subjects with rheumatic disease DEL/DEL homozygous for a polymorphism of the 3' untranslated regulatory region of HLA-G (HLA-G 14bp) than in the corresponding healthy controls (mean values 141.5ng/ml [SD: 166] vs 54.2ng/ml [SD: 35], p=0.009). Increasing maternal and cord blood levels of s-HLA-G concentrations among pregnant subjects with rheumatic diseases compared with controls suggest that autoimmune diseases prompt a maternal and fetal immune response that favors pregnancy immune tolerance.

Abstract
AIM The aim of this study was to evaluate the prevalence of erectile dysfunction (ED) in a sample of type 2 diabetic patients. As secondary endpoint, we evaluated the levels of some adipocytokines in patients with and without ED. MATERIAL AND METHODS We enrolled 220 males affected by type 2 diabetes mellitus. We administered the IIEF (International Index of Erectile Function), SAS (self-rating anxiety scale) and SDS (self-rating depression scale) questionnaires. We evaluated body mass index, glycemic control, fasting plasma insulin (FPI), homeostasis model assessment of insulin resistance index (HOMA-IR), lipid profile, sexual hormones, adiponectin (ADN), resistin, retinol binding protein-4 (RBP-4), visfatin, vaspin. RESULTS 52.9% of patients were affected by ED. Patients with a HbA1c <7% (53 mmol/mol) in all measurements in the two previous years had a lower incidence of ED, while the prevalence of ED increased with the increasing of times HbA1c was >7% (53 mmol/mol). Patients with ED had higher levels of triglycerides, and higher levels of FPI, 9.9 μU/ml vs 8.2 μU/ml (p<0.05). Resistin levels were higher in patients with ED compared to those without ED (p<0.05) and free testosterone was lower in patients affected by ED. CONCLUSIONS Almost half of type 2 diabetic patients attending our clinic were affected by ED and glycemic control seems to play a role in ED pathogenesis.

Abstract
The purpose of this study was to assess the validity of CO2 laser cordectomy in the treatment of early glottic cancer and to determine the impact of margin status on disease-free survival and of the operation on voice quality. This is a retrospective review of 169 patients. Quantitative and qualitative variables were statistically compared. The impact on overall and disease-free survivals of different variables was calculated by univariate and multivariate analyses. Ten-year overall and disease free-survivals were 75 % and 60 %, respectively. Age and clinical stage showed a significant negative impact on overall survival, while margin status both on overall and disease-free survivals. The degree of dysphonia was directly related to the extension of the resection. This series confirms the good oncologic and functional outcomes of laser surgery for Tis, T1 and selected T2 glottic tumors. Patients with positive margins should undergo a further treatment or a very close follow-up.

Abstract
BACKGROUND AND STUDY AIMS The HER2 status of small endoscopic biopsies is important for predicting the eligibility of patients with metastatic HER2-positive gastric cancer or gastro-esophageal junction (GEJ) cancer for anti-HER2 therapy approved by the U.S. Food and Drug Administration. The aim of this study was to identify the minimum biopsy set required to evaluate the HER2 status with confidence. PATIENTS AND METHODS A total of 103 consecutive patients with resected gastric cancer or GEJ cancer were retrospectively selected; 2 formalin-fixed, paraffin-embedded samples of each surgical specimen and all paired endoscopic biopsies were analyzed for HER2 status with both immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) methods. A total of 10 virtual biopsies were constructed by selecting areas 2.6 mm in diameter on the luminal side of digitalized slides obtained from the surgical specimens. The results of evaluating HER2 status in virtual biopsies, slides containing complete surgical specimens, and endoscopic biopsies were compared. The resulting minimum biopsy set was applied to the endoscopic biopsy series for validation. RESULTS A biopsy set containing a minimum of 5 samples was identified as the most accurate in predicting HER2 status (sensitivity, 92 %; specificity, 97 %). In only 3 of the 103 cases (2.9 %) did a comparison of the HER2 evaluation of virtual biopsies and that of entire slides show inconsistent results. Overall agreement between the endoscopic biopsies and surgical samples for HER2 IHC status increased from 78.4 % to 92.3 % when biopsy sets containing 4 or fewer samples were compared with biopsy sets containing 5 or more samples. CONCLUSIONS Although the recommendations suggest that 8 to 10 biopsies are necessary, the results show that a minimum set of 5 biopsies may be sufficient for reliable HER2 assessment in gastric cancer and GEJ cancer. However, endoscopists should be aware that a smaller sample size may be less accurate in selecting patients eligible for anti-HER2 therapy.

Abstract
PURPOSE This study was done to evaluate the intra- and inter-operator reproducibility of colour Doppler imaging (CDI) in assessing blood flow velocity in the ophthalmic (OA), central retinal (CRA) and short posterior ciliary arteries (SPCA) in healthy subjects. MATERIALS AND METHODS The right eye of two groups of eight healthy volunteers was examined. Two radiologists and two ophthalmologists, divided into pairs, measured peak systolic velocity (PSV), end-diastolic velocity (EDV) and resistivity index (RI) of each vessel using a different CDI device for each group. The concordance between two measurements was evaluated with Lin's concordance correlation coefficient (CCC). RESULTS Globally, very good degrees of intra-operator concordance were obtained for the PSV (0.859 cm/s), EDV (0.834 cm/s) and RI (0.859) of the OA. There was moderate concordance for PSV (0.574 cm/s) and EDV (0.594 cm/s) and good concordance for RI (0.694) for the CRA. Good degrees of concordance were obtained for the SPCA measurements. However, inter-operator concordance was found globally poor. CONCLUSIONS These data show that CDI measurements in retrobulbar vessels are operator dependent. To increase the intra-operator and inter-operator concordance, rules should be adopted for timing of the examination and positioning of the probe to minimise the pressure applied on the eye.

Abstract
BACKGROUND In the literature, the global endoscopic sinus surgery (ESS) success in the treatment of sinonasal inverted papilloma (IP) is 95%. This study was designed to describe a conservative endoscopic approach, based on research of the tumor's pedicle and treatment concentrated on its site of attachment, and to compare the results of this technique with the outcome of standard endoscopic treatment. METHODS Retrospective analysis of the patients treated in our institution for paranasal inverted papilloma (IP), between 2002 and 2011 with a minimum of 18 months follow-up was performed. Group A received a standard ESS including whole sinus demucosization (maxillary, ethmoid, frontal, or sphenoid sinus) and bony wall drilling. Group B patients instead underwent pedicle-oriented endoscopic surgery (POES); in this group, bony demucosization and drilling were selectively conducted around the site of pedicle attachment of the tumor. RESULTS The cohort included 73 patients (median age, 60.5 years; median follow-up, 58 months). Group A/group B consisted of 37/36 patients. IP persistence-recurrence for group A/group B was 0/1 cases. Oncological success for global endoscopic/group A/group B was 98.6% (72/73)/100% (37/37)/97.2% (35/36). We noticed a significant difference in surgical operative time and postoperative complication rate among the groups, in favor of POES technique. CONCLUSION Our data confirm the efficacy of the endonasal endoscopic treatment for sinonasal IP. Moreover, the even more conservative endoscopic treatment proposed (POES) seems to offer good control of the disease, shorter operating times, avoidance of unnecessary surgery with respect to uninvolved structures, and permits a follow-up aimed at the site of the pedicle attachment.

Abstract
Human papillomavirus (HPV) oncogenic activity is the result of viral oncogene E6 and E7 expression in infected cells. Oncogene expression analysis is, however, not part of the routine diagnostic evaluation of HPV-associated oropharyngeal squamous cell carcinoma (OPSCC) since it requires fresh tumor tissue. We compared the diagnostic accuracy of several methods commonly employed for HPV characterization in OPSCC with the results of the newly available HPV E6/E7 mRNA in situ hybridization (ISH) on formalin-fixed, paraffin-embedded biopsy samples, in order to establish if the latter should be introduced in the diagnostic routine to increase accuracy when fresh tissue is not available. p16 immunostain, DNA ISH for high-risk HPV genotypes, SPF LiPA amplification and genotyping, and HPV16 E6 amplification were performed on 41 consecutive OPSCC samples. Twenty (48.7%) cases were positive by mRNA ISH; sensitivity and specificity were 100% and 90% for p16, 90% and 100% for DNA ISH, 70% and 76% for SPF10 LiPA, 90% and 76% for E6 amplification. A diagnostic algorithm considering p16 immunostain as first step followed by either high-risk HPV DNA ISH or HPV16 E6 amplification in p16-positive cases correctly characterized 90% of mRNA-positive and all mRNA-negative cases; combining the 3 tests correctly identified all cases. While no stand-alone test was sufficiently accurate for classifying HPV-associated OPSCC, the high sensitivity and specificity of the established combination of p16 immunostain, DNA ISH, and HPV16 DNA amplification suggests that the introduction of labour- and cost-intensive mRNA ISH, is not necessary in the diagnostic routine of oropharyngeal tumors.

Abstract
BACKGROUND Brain vulnerability in the critically ill preterm newborn may be related to the burden of cerebral hypoxygenation and hypoperfusion during the immediate postnatal period. OBJECTIVE We determined the association between adverse outcomes [death or high grade intraventricular hemorrhage (IVH)] and continuous cerebral tissue oxygen saturation (rSO2), superior vena cava flow (SVCf) and cerebral fractional oxygen extraction (CFOE) in very low birth weight (VLBW) infants during the first 48 h of life. METHODS We studied a prospective cohort of 60 VLBW infants admitted to our neonatal intensive care unit within the first 6 h of life between March 2010 and June 2012. rSO2 (expressed as a number of summary measures) was continuously monitored with near-infrared spectroscopy (INVOS 5100 Somanetic) during the first 48 h of life, SCVf was measured at 4-6, 12, 24 and 48 h after birth, and CFOE was calculated. RESULTS The mean gestational age was 27.9 (SD 2.39); 8 infants died (13.3%) and 7 developed IVH grade III-IV: 1 in the alive group and 6 in the deceased group (p < 0.001). The odds ratio for death was 1.08 (95% CI: 1.015-1.15, p = 0.016) for each 10 periods of rSO2 values <40% in the first 48 h, and 4.2 (95% CI: 1.27-14.05, p = 0.019) for SVCf values <40 ml/kg/min. Among alive babies, mean CFOE decreased at 24, 36 and 48 h; among deceased babies it did not (p < 0.001). In the multivariate analyses, these results retained significance. CONCLUSIONS Both rSO2 ≤40% and SVCf <40 ml/kg/min independently increase the risk of death. The trend in CFOE supports the ischemic-hypoperfusion hypothesis as a mechanism for cerebral damage.

Abstract
Literature suggests that ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has excellent performance characteristics for diagnosis of sarcoidosis. However, many authors challenge the external validity of EBUS-TBNA results, as most studies were performed in referral centres by highly experienced investigators, and included populations with very high sarcoidosis prevalence. We performed a systematic review and meta-analysis to estimate the role of EBUS-TBNA for diagnosis of sarcoidosis in studies enrolling consecutive patients with lymphadenopathy detected at imaging studies, regardless of the suspected underlying clinical aetiology. The Pubmed, Embase, Cinahl, Web of Science and Cochrane Library databases were screened to identify the pertinent literature. Quality of eligible studies was assessed by Quality Assessment, Data Abstraction and Synthesis-2 criteria. Pooled diagnostic yield, sensitivity and specificity were calculated, and a summary receiver operating characteristic curve was constructed. Subgroup analysis was planned to identify possible sources of study heterogeneity. Fourteen studies, collectively involving 2097 patients, fulfilled eligibility criteria. The median prevalence of sarcoidosis was 15%. EBUS-TBNA had a pooled diagnostic yield of 0.79 (standard deviation, 0.24), a pooled sensitivity of 0.84 (95% confidence interval (CI), 0.79-0.88) and a pooled specificity of 1.00 (95% CI, 0.99-1.00). Only subgroup analysis exploring the influence of study design seemed to influence the observed inter-study heterogeneity for sensitivity, retrospective studies showing worst sensitivity than prospective ones. The results of EBUS-TBNA for diagnosis of sarcoidosis in clinically unselected populations are excellent and compare favourably with published results from studies conducted in selected populations. High-quality trials would be needed to evaluate factors possibly explaining the observed heterogeneity in sensitivity.

Abstract
BACKGROUND AND AIMS Similarly to diabetes type 2, patients with obesity show insulin resistance and autonomic and vascular abnormalities associated with increased morbidity and mortality. We tested whether arterial dysfunction in obese children may have a functional nature, reversible with appropriate interventions (e.g., by reduction of sympathetic activity), or else results from anatomic arterial modifications (likely irreversible). For this purpose, we tested whether deep breathing (an intervention known to transiently reduce sympathetic activity) could acutely improve arterial function, hence showing a functional abnormality. METHODS AND RESULTS A total of 130 obese children and 67 age-matched healthy normal-weight control children were recruited. Arterial function was measured by augmentation index (AIx), by direct analysis of blood pressure contour, and by pulse wave velocity (PWV), during spontaneous and controlled breathing. The markers of metabolic syndrome were evaluated at baseline. AIx showed increased values in obese male participants as compared with the control group. Slow breathing acutely reduced Aix in obese children, to a greater extent than in normal-weight control children. Similarly, the blood pressure contour showed higher values in obese children that were significantly attenuated by slow breathing. Baseline PWV was not altered in obese participants. The markers of metabolic syndrome correlated with AIx and PWV. CONCLUSIONS Obese subjects showed impaired arterial function. The acute improvement in vascular abnormalities with reduction in sympathetic activity indicates that this alteration was largely functional, likely related to initial autonomic dysfunction and to metabolic abnormalities. As a consequence, this study provides a rationale for strategies aiming at preventing arterial function deterioration in the early ages.

Abstract
BACKGROUND Mineral and bone disorders (MBD) in patients undergoing hemodialysis (HD) are a major clinical complication. Current therapeutic strategies do not attain the expected results. The Italian audit on mineral metabolism was implemented to investigate MBD management through a "patient-oriented" approach. METHODS Clinical and laboratory data pertinent to MBD from 509 prevalent adult patients on chronic HD were recorded and examined (audit), after which individual strategies were elaborated to improve MBD control. Their effectiveness was evaluated 6 months after the audit (Post-6). RESULTS The audit disclosed poor MBD control in a high percentage of patients (56 %). Low compliance to treatment was the major determinant of failure (in 43.5 % of cases). Logistic regression showed a direct correlation between high degree of compliance and the achievement of therapeutic targets, e.g. parathyroid hormone: odds ratio (OR) 2.48, p = 0.015. In contrast, a minority of the proposed interventions (14.7 %) included strategies to improve patient compliance. At Post-6, despite a significant increase in drug prescription (p < 0.05 vs. audit), the rate of successful MBD control was unchanged. CONCLUSIONS Low compliance with treatment is a major, but still neglected, cause of failure in the achievement of MBD control in HD patients.

Abstract
PURPOSE This study was conducted to prospectively investigate the interobserver reproducibility of controlled attenuation parameter (CAP) measurements and the relationship among the CAP and body mass index (BMI), gender and age. METHODS Consecutive subjects were studied using the M+ probe of the FibroScan device (Echosens, Paris, France). Measurements were performed by two raters (rater1 and rater2). Interobserver agreement was assessed by using the concordance correlation coefficient (CCC). The Pearson r coefficient was used to test correlation between two study variables, and linear regression was used for the multivariate model. RESULTS Three hundred fifty-one subjects (227 males and 124 females) were prospectively studied. The CCC was 0.82 (95 % CI 0.78-0.85) overall, 0.80 (95 % CI 0.75-0.85) for BMI <25 kg/m(2), 0.76 (95 % CI 0.69-0.84) for BMI 25-29 kg/m(2) and 0.65 (95 % CI 0.41-0.88) for BMI ≥30 kg/m(2). The CCC was 0.44 (95 % CI 0.31-0.56) for CAP values ≤240 dB/m and 0.72 (95 % CI 0.65-0.79) for CAP values >240 dB/m. In univariate analysis, age and BMI by gender were correlated with the CAP. Multiple regression analysis confirmed the relationship of the CAP with age and BMI, but not with gender. CONCLUSIONS The results of this study show that the interreader agreement in CAP measurement is good. In healthy volunteers, the CAP is strongly correlated with age and BMI.
