Endoscopic endonasal approach for loco-regional recurrent clivus chordomas

Introduction. Role of surgery for loco-regional recurrences of clivus chordomas (CCs) is still debated. It has been proposed in selected cases with a curative or with palliative intent, eventually followed by radiation or chemo/radiation treatments. Only limited data on the endoscopic endonasal approach (EEA) are available. Research question. To assess the role of EEA for loco-regional recurrent CCs. Materials and Methods. All consecutive loco-regional recurrent CCs operated by EEA at our Institution from 1998 to 2021 were identified. The extension of tumor resection, symptoms control, overall survival (OS), and progression free survival (PFS) were assessed. Results. Series includes 54 patients (53.7% females, mean age 55± 14 years). Surgery was planned with a resective aim in 35 (64.8%) patients, while it was palliative in 19 (35.2%). Gross tumor removal was achieved in 24 cases (44.4%). Main complications consisted of 2 (3.7%) CSF leaks. Further local relapses were observed in 30 (55.5%) patients after 25± 24 months; 29 (53.7%) patients deceased after 34 ± 31 months. OS and PFS were lower in these cases than primary surgeries (p<0.001 and p<0.001), but cases undergone surgery with a resective aim had a significant better OS and PFS than for those treated for palliation (p<0.001). Determinants of recurrences were tumoral size (p=0.48) and previous radiotherapy (p=009). Discussion and Conclusions. EEA has proven to be effective for loco-regional recurrent CCs alleviating patients symptoms and preserving their quality of life with limited morbidities. However, because overall prognosis is poor, EEA should be reserved to selected recurrent cases

Influence of Brand Equity on Milk Choice: A Choice Experiment Survey

 In the context of sustainable consumption buying local produce could support environmentally friendly production from the local economy. Our study estimates the preference weights that local consumers assign to some milk attributes including local origin and the influence on choice of a local brand of milk, which is traded by a local cooperative of producers in Umbria (Italy). Several preference segments are found amongst fresh and UHT milk buyers by employing a Latent Class model to analyze stated choice data. This specification allows us to verify whether consumers who have a better attitude towards local milk also prefer this brand to others, placing different values on the regional origin of milk

Anterolateral thigh free flap for tracheal reconstruction after parastomal recurrence

Background. Stomal recurrence after total laryngectomy is 1 of the most serious issues in head and neck surgery, both because of the complexity of its management and because of its morbidity. Prior to the introduction of free-tissue transfer, mediastinal tracheostomy has been the standard reconstructive procedure with high rate of complications. The ideal reconstructive solution to these problems must provide well-vascularized soft tissues that can cover the defect after resection and also allow suturing of the tracheal remnant to skin edges without tension. Methods and Results. We describe a case of a 56-year-old man with stomal recurrence after total laryngectomy treated by the use of a tubed anterolateral thigh (ALT) flap to elongate the shortened trachea and simultaneously cover the cervical skin defect. Conclusions. The ALT can be accepted as an ideal free-flap choice for stomal recurrence, because it has maximal reconstructive capacity and produces minimal donor-site morbidity. \ua9 2009 Wiley Periodicals, Inc

Through Time: Reconstructing Palaeolithic Occupations Through Use-Wear Analysis in the Middle Palaeolithic Site of Ciota Ciara (Borgosesia, Italy)

Lithic use-wear analysis, through defining site function and allowing reconstructing of patterns of human occupation, can contribute to our understanding of archaeological palimpsests. The Ciota Ciara cave represents an excellent case study for this methodology. Multidisciplinary research so far conducted on the materials recovered from the atrial sector of the cave distinguishes three archaeological units from a Middle Palaeolithic occupation of the site: stratigraphic units (SUs) 13, 14, and 15. Each unit is interpreted as referring to a period of numerous, superimposed episodes of human occupation, the characteristics of which we try to reconstruct and present in this work through use-wear studies. The functional analysis of lithic industries from the upper units (13 and 14) has already been published previously; here, we report corresponding new data from the lowest level, SU 15. By comparing the use-wear results from the three units and integrating the findings with data from the geoarchaeological, palaeontological, zooarchaeological, and technological studies, we attempt to reconstruct the different phases of human occupation represented in the site through time, contributing to current interpretations regarding settlement dynamics and human behaviour in the Middle Palaeolithic of north-western Italy

Lack of efficacy of Lactobacillus GG in reducing pulmonary exacerbations and hospital admissions in children with cystic fibrosis: A randomised placebo controlled trial

Background: Intestinal dysbiosis has been described in Cystic Fibrosis (CF) and probiotics have been proposed to restore microbial composition. Aim of the study was to investigate the effects of Lactobacillus rhamnosus GG (LGG) on clinical outcomes in children with cystic fibrosis (CF). Methods: A multicentre, randomised double-blind, clinical trial was conducted in children with CF. After 6months of baseline assessment, enrolled children (2 to 16years of age) received Lactobacillus GG (6\uc3\u97109CFU/day) or placebo for 12months. Primary outcomes were proportion of subjects with at least one pulmonary exacerbation and hospitalisation over 12months. Secondary endpoints were total number of exacerbations and hospitalisations, pulmonary function, and nutritional status. Results: Ninety-five patients were enrolled (51/95 female; median age of 103. \uc2\ub1. 50. months). In a multivariate GEE logistic analysis, the odds of experiencing at least one exacerbation was not significantly different between the two groups, also after adjusting for the presence of different microbial organisms and for the number of pulmonary exacerbations within 6. months before randomisation (OR 0.83; 95% CI 0.38 to 1.82, p = 0.643). Similarly, LGG supplementation did not significantly affect the odds of hospitalisations (OR 1.67; 95% CI 0.75 to 3.72, p = 0.211). No significant difference was found for body mass index and FEV1. Conclusions: LGG supplementation had no effect on respiratory and nutritional outcomes in this large study population of children with CF under stringent randomised clinical trial conditions. Whether earlier interventions, larger doses, or different strains of probiotics may be effective is unknown

SICE national survey: current status on the adoption of laparoscopic approach to the treatment of colorectal disease in italy

The real di usion of laparoscopy for the treatment of colorectal diseases in Italy is largely unknown. The main purpose of the present study is to investigate among surgeons dedicated to minimally invasive surgery, the volume of laparoscopic colorectal procedures, the type of operation performed in comparison to traditional approach, the indication for surgery (benign and malignant) and to evaluate the di erent types of technologies used. A structured questionnaire was developed in collaboration with an international market research institute and the survey was published online; invitation to participate to the survey was issued among the members of the Italian Society of Endoscopic Surgery (SICE). 211 surgeons working in 57 surgical departments in Italy ful lled and answered the online survey. A total of 6357 colorectal procedures were recorded during the year 2015 of which 4104 (64.1%) were performed using a minimally invasive approach. Colon and rectal cancer were the most common indications for laparoscopic approach (83.1%). Left colectomy was the operation most commonly performed (41.8%), while rectal resection accounted for 23.5% of the cases. Overall conversion rate was 5.9% (242/4104). Full HD standard technology was available and routinely used in all the responders’ centers. The proportion of colorectal resec- tions that are carried out laparoscopically in dedicated centers has now reached valuable levels with a low conversion ra

The results of this Consensus Conference, presented to the 115th National Congress of the Italian Society of Surgery, and approved in plenary session, are reported in the present paper

Abstracts from the 23rd Italian congress of Cystic Fibrosis and the 13th National congress of Cystic Fibrosis Italian Society

Cystic Fibrosis (CF) occurs most frequently in caucasian populations. Although less common, this disorder have been reported in all the ethnicities. Currently, there are more than 2000 described sequence variations in CFTR gene, uniformly distributed and including variants pathogenic and benign (CFTR1:www.genet.sickkids.on.ca/). To date,only a subset have been firmily established as variants annotated as disease-causing (CFTR2: www.cftr2.org). The spectrum and the frequency of individual CFTR variants, however, vary among specific ethnic groups and geographic areas. Genetic screening for CF with standard panels of CFTR mutations is widely used for the diagnosis of CF in newborns and symptomatic patients, and to diagnose CF carrier status. These screening panels have an high diagnostic sensitivity (around 85%) for CFTR mutations in caucasians populations but very low for non caucasians. Developed in the last decade, Next-Generation Sequencing (NGS) has been the last breakthrough technology in genetic studies with a substantial reduction in cost per sequenced base and a considerable enhancement of the sequence generation capabilities. Extended CFTR gene sequencing in NGS includes all the coding regions, the splicing sites and their flankig intronic regions, deep intronic regions where are localized known mutations,the promoter and the 5'-3' UTR regions. NGS allows the analysis of many samples concurrently in a shorter period of time compared to Sanger method . Moreover, NGS platforms are able to identify CFTR copy number variation (CNVs), not detected by Sanger sequencing. This technology has provided new and reliable approaches to molecular diagnosis of CF and CFTR-Related Disorders. It also allows to improve the diagnostic sensitivity of newborn and carrier screeningmolecular tests. In fact, bioinformatics tools suitable for all the NGS platforms can filter data generated from the gene sequencing, and analyze only mutations with well-established disease liability. This approach allows the development of targeted mutations panels with a higher number of frequent CF mutations for the target populationcompared to the standard panels and a consequent enhancement of the diagnostic sensitivity. Moreover, in the emerging challenge of diagnosing CF in non caucasians patients, the possibility of customize a NGS targeted mutations panel should increase the diagnostic sensitivity when the target population has different ethnicities
