Once daily nebulized beclomethasone is effective in maintaining pulmonary function and improving symptoms in asthmatic children

Background and Aim. Compliance with long-term inhaled therapy in asthma is often poor, but it is likely to be improved with a simplified administration, once daily.The present study was designed to assess whether, in childhood asthma, a single dose of nebulized beclomethasone dipropionate once daily was as effective and safe as the same total daily dose administered twice daily. Methods. Asthmatic children, not treated with inhaled steroids for at least a month preceding the study and using short-acting bronchodilators more than once a week were enrolled in a double-blind, double dummy, randomised, multicentric study. After a two week run-in period on nebulised twice daily 400 mcg beclomethasone dipropionate, patients were randomly assigned to twelve weeks of treatment with 800 mcg nebulised beclomethasone dipropionate daily, either in single dose (o.d. group) or divided into two 400 mcg doses (b.i.d. group). Results. 65 children (mean age 8.6 years, mean FEV1 81% of predicted), were valuable for intention to treat. During the run-in period, a significant improvement in FEV1, FVC, morning and evening PEF values and clinical scores was observed. Children then entered the randomised trial: 32 were included in the o.d. group and 33 in the b.i.d. group. During the twelve week treatment period, the observed improvement in pulmonary function parameters was maintained in both treatment groups. Morning and evening PEF showed a progressive slight increase as well as PEF diurnal variability showed a progressive reduction in the two treatment groups during the whole study period without reaching statistical significance. Moreover, in both treatment groups a similar progressive increase in symptom free nights and days and in the percentage of children achieving total asthma symptoms control was detected. Finally, no significant changes in urinary cortisol/creatinine ratio were observed throughout the study period and between groups. Conclusions. A daily dose of 800 mcg of beclomethasone, administered for twelve weeks with a nebuliser either once or twice daily provide similar efficacy in maintaining pulmonary function and symptoms of asthmatic children, with a good tolerability profile

The Role of Spleen and Liver Elastography and Color-Doppler Ultrasound in the Assessment of Transjugular Intrahepatic Portosystemic Shunt Function

The reference standard for assessing transjugular intrahepatic portosystemic shunt (TIPS) function is venography with portosystemic pressure gradient (PPG) measurement. This procedure is invasive and expensive; thus, we assessed the feasibility, reproducibility and diagnostic accuracy of color-Doppler ultrasound (CDUS) and spleen and liver stiffness (LS) measurements for identifying TIPS dysfunction. Twenty-four patients (15 undergoing TIPS placement and nine undergoing TIPS revision) consecutively underwent CDUS examination and LS and spleen stiffness (SS) determination by transient elastography (TE) and point shear-wave elastography (pSWE). All parameters were taken before TIPS placement/revision (1\u201315 d before) and 24 h after, just before revision by venography. pSWE inter-observer agreement was assessed by intra-class correlation coefficient (ICC). CDUS and elastographic data were correlated (Pearson coefficient) with pressure gradients (hepatic venous pressure gradient [HVPG], PPG). Main determinants of TIPS dysfunction were investigated by linear regression. Forty-nine paired examinations were performed in total: 49 (100%) SS reliable measurements by pSWE and 38 (88%) by TE. The ICC for pSWE values was 0.90 (95% confidence interval [CI] 0.81\u20120.94). SS values significantly correlated with HVPG and PPG (R = 0.51, p = 0.01). The area under the Receiver-Operating Characteristic (AUROC) curve of SS for diagnosing TIPS dysfunction was 0.86 (95% CI 0.70\u20120.96) using a 25 kPa cutoff. At multivariate analysis, the flow direction of the intrahepatic portal vein branches and SS values were independently associated to TIPS dysfunction. The intrahepatic portal vein branches flow direction and SS value are two simple, highly sensitive parameters accurately excluding TIPS dysfunction. SS measurement by pSWE is feasible, reproducible and both positively and significantly correlates with HVPG and PPG values

Updated Italian recommendations for the diagnosis, treatment and follow-up of the first febrile urinary tract infection in young children

Aim: Our aim was to update the recommendations for the diagnosis, treatment and follow-up of the first febrile urinary tract infection in young children, which were endorsed in 2012 by the Italian Society of Pediatric Nephrology. Methods: The Italian recommendations were revised on the basis of a review of the literature published from 2012 to October 2018. We also carried out an ad hoc evaluation of the risk factors to identify children with high-grade vesicoureteral reflux or renal scarring, which were published in the previous recommendations. When evidence was not available, the working group held extensive discussions, during various meetings and through email exchanges. Results: Four major modifications have been introduced. The method for collecting urine for culture and its interpretation has been re-evaluated. We have reformulated the algorithm that guides clinical decisions to proceed with voiding cystourethrography. The suggested antibiotics have been revised, and we have recommended further restrictions of the use of antibiotic prophylaxis. Conclusion: These updated recommendations have now been endorsed by the Italian Society of Pediatric Nephrology and the Italian Society for Pediatric Infectivology. They can also be used to compare other recommendations that are available, as a worldwide consensus in this area is still lacking

Multimodality treatment of hepatocellular carcinoma : How field practice complies with international recommendations

Background: Management of hepatocellular carcinoma (HCC) is framed within standardized protocols released by Scientific Societies, whose applicability and efficacy in field practice need refining. Aim: We evaluated the applicability and effectiveness of guidelines for the treatment of HCC of the American Association for the Study of the Liver (AASLD). Methods: 370 consecutive cirrhotic patients with de-novo HCC in different stages (253 BCLC A, 66 BCLC B, 51 BCLC C) received treatment through a multidisciplinary team (MDT) decision and were followed until death or end of follow-up. Results: Adherent treatment to AASLD recommendations was in 205 (81%) BCLC A patients, 36 (54%) BCLC B, and 27 (53%) BCLC C. Radiological complete response was achieved in 165 (45%) patients after the first-line treatment, in 22 (19%) after a second-line and in 9 (23%) after a third line treatment. Adherence to AASLD recommendation allowed a lower yearly mean mortality rate in BCLC A patients compared to other treatment (5.0% vs 10.4% p = 0.004), whereas upward treatment stage migration compared to the standard of care was associated to reduced yearly mortality in BCLC B (8.6% vs 20.7%, p = 0.029) and BCLC C (42.6% vs 59.0%, p = 0.04) patients.Conclusions: HCC multimodality treatment including other than first-line therapy is common in clinical practice and impact on the achievement of complete response. Personalized treatment was able to provide survival benefits to patients whose profile is not accounted for by international recommendations, which need to be amended

Prenatal tobacco smoke exposure increases hospitalizations for bronchiolitis in infants

BACKGROUND: Tobacco smoke exposure (TSE) is a worldwide health problem and it is considered a risk factor for pregnant women's and children's health, particularly for respiratory morbidity during the first year of life. Few significant birth cohort studies on the effect of prenatal TSE via passive and active maternal smoking on the development of severe bronchiolitis in early childhood have been carried out worldwide. METHODS: From November 2009 to December 2012, newborns born at ≥ 33 weeks of gestational age (wGA) were recruited in a longitudinal multi-center cohort study in Italy to investigate the effects of prenatal and postnatal TSE, among other risk factors, on bronchiolitis hospitalization and/or death during the first year of life. RESULTS: Two thousand two hundred ten newborns enrolled at birth were followed-up during their first year of life. Of these, 120 (5.4%) were hospitalized for bronchiolitis. No enrolled infants died during the study period. Prenatal passive TSE and maternal active smoking of more than 15 cigarettes/daily are associated to a significant increase of the risk of offspring children hospitalization for bronchiolitis, with an adjHR of 3.5 (CI 1.5-8.1) and of 1.7 (CI 1.1-2.6) respectively. CONCLUSIONS: These results confirm the detrimental effects of passive TSE and active heavy smoke during pregnancy for infants' respiratory health, since the exposure significantly increases the risk of hospitalization for bronchiolitis in the first year of lif

Risk factors for bronchiolitis hospitalization during the first year of life in a multicenter Italian birth cohort

BACKGROUND: Respiratory Syncytial Virus (RSV) is one of the main causes of respiratory infections during the first year of life. Very premature infants may contract more severe diseases and 'late preterm infants' may also be more susceptible to the infection. The aim of this study is to evaluate the risk factors for hospitalization during the first year of life in children born at different gestational ages in Italy. METHODS: A cohort of 33-34 weeks gestational age (wGA) newborns matched by sex and age with two cohort of newborns born at 35-37 wGA and > 37 wGA were enrolled in this study for a three-year period (2009-2012). Hospitalization for bronchiolitis (ICD-9 code 466.1) during the first year of life was assessed through phone interview at the end of the RSV season (November-March) and at the completion of the first year of life. RESULTS: The study enrolled 2314 newborns, of which 2210 (95.5 %) had a one year follow-up and were included in the analysis; 120 (5.4 %) were hospitalized during the first year of life for bronchiolitis. Children born at 33-34 wGA had a higher hospitalization rate compared to the two other groups. The multivariate analysis carried out on the entire population associated the following factors with higher rates for bronchiolitis hospitalization: male gender; prenatal treatment with corticosteroids; prenatal exposure to maternal smoking; singleton delivery; respiratory diseases in neonatal period; surfactant therapy; lack of breastfeeding; siblings <10 years old; living in crowded conditions and/or in unhealthy households and early exposure to the epidemic RSV season. When analysis was restricted to preterms born at 33-34 wGA the following variables were associated to higher rates of bronchiolitis hospitalization: male gender, prenatal exposure to maternal smoking, neonatal surfactant therapy, having siblings <10 years old, living in crowded conditions and being exposed to epidemic season during the first three months of life. CONCLUSION: Our study identified some prenatal, perinatal and postnatal conditions proving to be relevant and independent risk factors for hospitalization for bronchiolitis during the first year of life. The combination of these factors may lead to consider palivizumab prophylaxis in Italy

Early leaf removal impact on volatile composition of Tempranillo wines

Early defoliation is a very innovative technique in viticulture used for yield management. The effects of early leaf removal performed manually and mechanically at two different phenological stages, pre-bloom and fruit set, on the volatile composition of Tempranillo (Vitis vinifera L.) wines were studied. Volatiles were identified and quantified by gas chromatography Early leaf removal only modified the total concentrations of C6 compounds and acetates, whereas total alcohols, esters, volatile acids and terpenes remained generally unaffected. Early defoliation induced a significant reduction in C6 compounds and increased the concentrations of acetates in Tempranillo wines. An effect of timing (pre-bloom vs fruit set) alone was observed for all acetates analysed. Regarding the method of defoliation (manual vs mechanical), significant differences in some ethyl ester (ethyl-2-methylbutyrate and ethyl octanoate) and volatile acid concentrations were observed among treatments. Ethyl octanoate, 2-phenylethyl acetate, 3-methylbutyl acetate and hexanoic acid, with OAV (odour activity value) > 1 and mainly fruity and floral odour descriptors, showed higher levels after early defoliation treatments compared with non-defoliated vines. Principal component analysis illustrated the difference in wines from defoliated and non-defoliated treatments based on their volatile composition. It can be concluded that early leaf removal significantly modified the wine aroma compounds, increasing or decreasing several of these compounds.We thank the Agencia de Desarrollo Economico de La Rioja (ADER) and the Ministerio de Ciencia e Innovacion for their financial support (ADER-2006-I-ID-00157 and AGL2007-60378 respectively).
