Prise en charge des complications de la chirurgie partielle du larynx
Introduction : Le cancer du larynx est un cancer fréquent occupant la première place des cancers des voies aéro-digestives chez l’homme en Tunisie. Le tabac est le principal facteur favorisant surtout s’il est associé à l’éthylisme chronique. Il s’agit le plus souvent d’un carcinome épidermoïde plus ou moins différencié. Son pronostic est généralement bon, en raison de son développement dans un tube rigide bien limité et d’un traitement chirurgical actuellement bien codifié. La chirurgie partielle du cancer du larynx est une chirurgie à risque de complications postopératoires nécessitant une prise en charge adéquate.Patients et méthodes : Notre série comprend 54 patients ayant bénéficié d’une chirurgie partielle du larynx au sein du service de chirurgie carcinologique de l’institut Salah Azaiez sur une période de 15 ans (1997-2011).But : Présenter notre expérience en matière de prise en charge des complications de la chirurgie partielle du larynx.Résultats : La moyenne d’âge de nos patients était de 54,9 ans avec des extrêmes allant de 33 à 69 ans. La prédominance masculine était nette avec un sex-ratio de 26. La consommation tabagique était notée dans 92,6% des cas et la dysphonie était présente chez 40 patients porteurs d’une tumeur à localisation glottique. Six types d’interventions ont été pratiqués: cordectomie (9 cas), laryngectomie fronto-latérale (4 cas), laryngectomie frontale antérieure reconstructive type Tucker (10 cas), laryngectomie partielle supra-cricoïdienne avec crico-hyoïdopexie (CHP) (4 cas), laryngectomie partielle supra-cricoïdienne avec crico-hyoïdo-épiglottopexie (CHEP) (24 cas) et laryngectomie horizontale supra-glottique (3 cas). Une antibioprophylaxie était administrée chez 79,6% des patients pour une durée moyenne de 7 jours. Les complications postopératoires ont été analysées et discutées en fonction du type de la chirurgie partielle pratiquée et du type d’antibiothérapie utilisée. Ces complications étaient les suivantes: infection du trachéostome (20,4%), infection de paroi (5 cas), complications respiratoires (29,6%), emphysème sous cutané (7,4%), fistule salivaire (1 cas) et pancréatite aigüe (1 cas).Conclusion : Cette étude montre dans l’ensemble des bons résultats tant sur le plan infectieux que respiratoires, justifiant ainsi l’importance de la prise en charge des complications de la chirurgie partielle du cancer du larynx.Introduction : Laryngeal cancer is a common cancer occurring mainly in men. Smoking is the main risk factor especially if associated with chronic alcoholism. Squamous cell carcinoma is the most common histologic type. Prognosis is generally good, due to the development of the tumor in a very limited rigid tube and to a well-codified surgical treatment. Partial surgery of laryngeal cancer is characterized by postoperative complications requiring an adequate management.Methods : Our series includes 54 cases of laryngeal cancer treated with partial laryngectomy in the ENT department of Salah Azaiez Institute over a period of 15 years from 1997 to 2011.Objective : To present our experience in the management of partial laryngeal surgery complications.Results : Average age of our patients was 54.9 years ranging from 33 to 69 years. Male predominance was marked with a sex ratio of 26. Tobacco abuse was found in 92.6%. Dysphonia was the most common symptom found in 40 patients with glottic cancer. Six varieties of partial laryngectomy were performed: cordectomy (9 cases), fronto-lateral laryngectomy (4 cases), fronto-anterior reconstructive laryngectomy (10 cases), partial supra-cricoid laryngectomy with CHP (4 cases), partial supra-cricoid laryngectomy with CHEP (24 cases) and supra glottic horizontal laryngectomy (3 cases). 79.6 % of our patients received prophylactic antibiotics for an average of 7 days. Postoperative complications were analyzed and discussed in terms of the type of surgery performed and the antibiotic used. Complications observed were: infection of the tracheostoma (20.4%), parietal infection (5 cases), respiratory complications (29.6%), subcutaneous emphysema (7.4%), salivary fistula (1 case) and acute pancreatitis (1 case).Conclusion : This study shows overall good results for partial laryngeal cancer surgery with minimal post-operative complications and oncologic failure justifying the importance of an early management of these complications

Groundwater quality assessment for different uses using various water quality indices in semi-arid region of central Tunisia
The Hajeb Layoun-Jelma basin, located in the central Tunisia, is the principal source of water supply for Sidi Bouzid and Sfax region. The over-abstraction from this groundwater, since 1970, and the intensive agriculture activities led to the degradation of the water quantity and quality. The quality evaluation for this groundwater is very important tool for sustainable development and decision for water management. A total of 28 groundwater samples, from shallow, springs, and deep aquifers, were collected, storage and analyzed to evaluate its quality suitability for domestic and agriculture purposes using geographic information system and geochemical methods. For the both aquifers, the abundance of cations: Na > Mg > Ca > K, and of anions in the order: Cl > HCO3 > SO4. The dominant hydrochemical facies, for the shallow aquifer and springs, are Na-Cl and Ca-Mg-Cl; for the deep aquifer, the geochemical facies are Na-Cl, Ca-Mg-Cl, and Ca-Cl. The comparison of the major parameters and the chemical data with the World Health Organization standards and the national standards indicate that this groundwater is suitable for drinking, except in some samples, with high salinity concentrations. The water quality was assessed, for drinking uses, using "water quality index," "entropy," and "improved water quality index." The results mentioned that the improved water quality index is the best method which indicated that the poor water quality coincide with the Na-Cl water type. The entropy method and the water quality index present the optimistic methods. The irrigation suitability assessment was made using various parameters (SAR, TH, % Na, PI, MH, KR, EC). The results revealed that the majority of samples in Hajeb Layoun-Jelma basin are not appropriate for irrigation uses
Offshore wind farm layouts designer software's
Offshore wind energy can be considered one of the renewable energy sources with high force potential installed in marine areas. Consequently, the best wind farm layouts identified for constructing combined offshore renewable energy farms are crucial. To this aim, offshore wind potential analysis is essential to highlight the best offshore wind layouts for farm installation and development. Furthermore, the offshore wind farm layouts must be designed and developed based on the offshore wind accurate assessment to identify previously untapped marine regions. In this case, the wind speed distribution and correlation, wind direction, gust speed and gust direction for three sites have been analyzed, and then two offshore wind farm layout scenarios have been designed and analyzed based on two offshore wind turbine types in the Northwest Persian Gulf. In this case, offshore wind farm layouts software and tools have been reviewed as ubiquitous software tools. The results show Beacon M28 and Sea Island buoys location that the highest correlation between wind and gust speeds is between 87% and 98% in Beacon M28 and Sea Island Buoy, respectively. Considerably, the correlation between wind direction and wind speed is negligible. The Maximum likelihood algorithm, the WAsP algorithm, and the Least Squares algorithm have been used to analyze the wind energy potential in offshore buoy locations of the Northwest Persian Gulf. In addition, the wind energy generation potential has been evaluated in different case studies. For example, the Umm Al-Maradim buoy area has excellent potential for offshore wind energy generation based on the Maximum likelihood algorithm, WAsP algorithm, and Least Squares algorithm

A credibility and classification-based approach for opinion analysis in social networks
© Springer International Publishing Switzerland 2016. There is an ongoing interest in examining users’ experiences made available through social media. Unfortunately these experiences like reviews on products and/or services are sometimes conflicting and thus, do not help develop a concise opinion on these products and/or services. This paper presents a multi-stage approach that extracts and consolidates reviews after addressing specific issues such as user multiidentity and user limited credibility. A system along with a set of experiments demonstrate the feasibility of the approach
Impact of credibility on opinion analysis in social media
© 2018 IOS Press. All rights reserved. In conjunction with the rapid growth and adoption of social media, people are more and more willing to share their personal experiences and opinions about products and/or services with the community. Opinions could be the basis of developing systems that would advise future users on how to proceed with any purchase without risking any disappointment. Unfortunately, opinions are not always genuine due to for instance, biased users as well as mixed feedback coming from the same users (i.e., multi-identity). This paper presents an approach for opinion analysis using credibility as a decisive criterion for supporting future users make sound decisions. The effectiveness of this approach has been tested using opinions posted on Twitter
