Abstract
This work constitutes a new trial to enhance the properties of palladium supported on alumina modified with zirconium used as catalysts for methane combustion. The effect of the support drying mode is studied. For this aim, Al2O3-ZrO2 binary oxides with zirconium loading of 2 and 5% in weight were prepared using sol-gel process then dried under ordinary or supercritical conditions. Palladium with a loading of 0.5% was deposited on the support by wet impregnation. Several techniques have been used to investigate differences between the two types of the derived catalysts.

Abstract
Introduction : À l’heure actuelle, le retentissement des cancers utérins, ainsi que leur traitement sur l’image du corps, demeure un sujet peu étudié en Tunisie et souvent négligé aussi bien par les praticiens, les malades et leurs partenaires.
Méthodes : Il s’agit d’une étude transversale descriptive colligeant 100 patientes tunisiennes suivies à l’institut Salah- Azaïez pour un cancer de l’endomètre ou du col utérin confirmés histologiquement et non métastatiques, avec un recul supérieur à six mois. Nous avons utilisé l’échelle Body Image Scale (BIS) et Female Sexual Function Index (FSFI). Nous avons collecté les antécédents personnels et familiaux, et différentes données sociodémographiques des patientes.
Résultats : Dans notre étude, 40 % des patientes ont des troubles de l’image du corps. La moyenne du score BIS était de 12,03 avec des extrêmes allant de 0 à 30 avec un écarttype de 7,88. En analyse univariée, l’absence du soutien familial, l’altération de la relation de couple et de la relation sexuelle, la mauvaise tolérance de la chirurgie et la curiethérapie utérovaginale étaient significativement associées à l’altération de l’image corporelle. En analyse multivariée, le bas niveau socio-économique était le facteur indépendant protecteur du trouble de l’image du corps, et la dysfonction sexuelle était le facteur indépendant prédicteur de ce trouble.
Conclusions : Le manque de communication des patientes avec leur conjoint et avec l’équipe de soin constitue l’un des principaux obstacles lorsqu’il s’agit de reconnaître et de traiter ce problème. Des stratégies préventives visant à maintenir une image corporelle positive chez ces femmes devraient être entreprises.

Abstract
Introduction Ethanol is widely consumed by the world’s population, especially young people as part of their university life. In Tunisia, surveys and studies about consumption of ethanol among students are rare or even exceptional. Objectives To evaluate the extent of the consumption of ethanol among pharmacy students in Monastir University, from the first year to residency, and to define the factors associated to this consumption. Methods This study was used to collected information about the participants using a questionnaire that covers the different parameters of the consumption of ethanol during student life and the factors influencing this consumption. Results 154 participants aged 23.61 years +/- 2.63 among them 37.7% were men and 62.3% women. The prevalence of ethanol consumption was 44.8 %. The main reason for dirking was to party (79.2%). The consumption of ethanol was significantly associated with sex (p=0), place of residence (p=0.047), frequency of hang-outs (p=0), sex life (p=0) and students perception of the alcohol-health relationship (p=0). Various health problems were related to the frequency of consumption of ethanol, such as memory problems (p=0.002), violence and injuries (p=0.014). Conclusions The findings of this study underline the need to develop specific studies and general population surveys in order to better assess the situation in Tunisia and to put in place appropriate prevention strategies, such as information and awareness campaigns, aimed at reducing or at least rationing the consumption of ethanol. Conflict of interest No significant relationships.

Abstract
Introduction In Tunisia, the use of cannabis has become an important phenomenon in the society that not well attested by epidemiological studies. Objectives The purpose of this work is to study the socio-demographic criteria of student of the faculty of Pharmacy of Monastir and risk factors encouraging them to consume cannabis and to estimate the extent of the phenomenon of dependence occurring among students. Methods A questionnaire composed of 45 questions was sent to students of the Faculty of Pharmacy of Monastir via the internet. The data was collected and analyzed using the software’ Google forms’ and ‘statistical package for social Science’ (SPSS) Results The prevalence of cannabis use among students of the faculty of Pharmacy was worrying, increasing to 21.4 %, for moments of pleasure and relaxation of the stressful life (p=0 et p=0.008). The frequency of cannabis use had a significant impact on the desire to stop cannabis use (p=0.012). Of the 55 consumers, only 5 tried to stop or reduce cannabis use. About 88% of participants indicated that cannabis was responsible for psychological dependence. Polydrug use (tobacco, alcohol, other drugs) had a significant influence on this use (p=0). Conclusions The scourge of cannabis use has invaded not only universities, but also high schools and colleges. At the end of this work, we propose debates to find the necessary means to protect cannabis users cannabis and treat dependents.

Abstract
Background: Ochratoxin A (OTA) and Aflatoxin B1 (AFB1) are toxic secondary metabolites produced by certain mold species. In this primarily survey, we examined the OTA and AFB1 contamination of pearl millet grains distributed in Tunisia.
Methods: Twenty-five pearl millet (Pennisetum glaucum L.) samples from different regions of Tunisia were analyzed by High Performance Liquid Chromatography coupled with fluorescence detector in order to evaluate the contamination with of AFB1 and OTA. Statistical tests were performed with XLSTAT 2018.
Results: AFB1 and OTA were detected in 32 and 28% millet samples, respectively. Mean amounts of these mycotoxins in the contaminated samples were of 24.54±17.54 µg/kg for OTA and 22.72±23.09 µg/kg for AFB1. Approximately, 28 and 24% of analyzed samples were found above the European Union limits for AFB1 and OTA, respectively. The estimated daily intake of OTA and AFB1 were 3.76 and 3.89 ng/kg b.w. per day, respectively. No significantly (p>0.05) difference in OTA and AFB1 contamination rate was found between samples taken from different regions.
Conclusion: Consumption of millet in Tunisia might be an important contributing factor to the risk of dietary exposure to OTA and AFB1

Abstract
Salinity is one of the major abiotic stresses threatening crop production and yield worldwide. Breeding programmes are therefore needed to improve yield under cultivation in soil. Traits from locally adopted landraces provide a resource to assist breeding of novel elite genotypes. Here, we examine differentially expressed proteins by performing comparative proteomic profiling of the albumin/globulin grain fraction of Tunisian barley genotype landraces with contrasting salinity tolerance. Tunisian barley Boulifa (B, tolerant) and Testour (T, sensitive) mature grains were assessed in 2-DE profiles. Differentially expressed spots, with an abundance enhanced 1.5-fold in the grain, were subjected to MALDI TOF/TOF MS for identification. Distinctiveness between tolerant and sensitive genotypes was proved in the albumin/globulin fraction using PCA; 64 spots showed significant differential abundance. Increased accumulation of 40 spots was confirmed in Boulifa with, interestingly, four genotype-specific spots. Two of these four spots were sHSP. Proteins with highest abundance were serpin Z7, 16.9 KDa Class I HSP and phosphogluconolactonase 2. Proteins such as expansin, kiwellin, kinesin and succinyl-CoA ligase were identified for the first time in barley grain. Moreover, ß-amylase, LEA family and others were identified as abundant in Boulifa. On the other hand, proteins more accumulated in Testour are implicated mainly in ROS scavenging and protease inhibition. Our results clearly indicate proteomic contrast between the two selected genotypes. With identification of specific HSP, high abundant stress-protective and other defined proteins, we provide biochemical traits that will support breeding programmes to address the threat of salinity in agricultural production.

Abstract
INTRODUCTION We report the first case of squamous cell carcinoma (SCC) of the thyroid gland coexisting with papillary thyroid carcinoma (PTC) and Hashimoto's thyroiditis and discuss various theories concerning the histogenesis of SCC of the thyroid gland and the optimal treatment strategy. CASE REPORT A 54-year-old woman presented with an anterior neck mass measuring 4cm on clinical examination. Imaging showed a suspicious thyroid nodule invading the trachea. Total thyroidectomy with bilateral central lymph node resection was performed. Histological examination revealed tall cell variant of papillary thyroid carcinoma associated with SCC of the right lobe of the thyroid and Hashimoto's thyroiditis. Immunohistochemistry of the SCC showed positive staining for p53 and Ki67 and negative staining for thyroglobulin. The patient underwent adjuvant radioactive iodine therapy and radiotherapy. With postoperative follow-up of 24 months, the patient was in good health. DISCUSSION In conclusion, the most probable origin of SCC in this case was malignant transformation from Hashimoto's thyroiditis following a phase of metaplasia. This immunohistological profile is associated with a better prognosis. Optimal treatment consists of extensive surgical resection of tumour tissuefollowed by radiotherapy.

Abstract
PURPOSE We represent in this study the long term results of docetaxel, cisplatin and 5-fluorouracil induction chemotherapy followed by concurrent chemoradiotherapy in Tunisian patients with locally advanced nasopharyngeal carcinoma. The objective of our study is to analyse the efficacy as well as the toxicity of this therapeutic protocol. PATIENTS AND METHODS Between January 2004 and December 2008, 32 patients with locoregional advanced non metastatic disease (T2b or above and/or N1 or above AJCC 2002) were treated in our institution by three cycles of docetaxel, cisplatin and 5-fluorouracil induction chemotherapy every 21 days followed by concurrent chemoradiotherapy. Conventional radiotherapy was delivered using a cobalt 60 machine during 7 weeks with weekly cisplatin (40mg/m2). RESULTS Twenty-nine patients (90%) had presented an objective clinical response in lymph nodes after neoadjuvant chemotherapy, with a complete response in 28%. Acute toxicity of docetaxel, cisplatin and 5-fluorouracil induction chemotherapy was dominated by vomiting (59%), asthenia (40.6%), diarrhea (34.4%) and febrile neutropenia (15.6%). The complete response rate after the end of treatment was around 80%. The 5 years overall survival and disease-free survival were respectively 68.2% and 67.5%. CONCLUSION Our results, in this field of study, are encouraging with acceptable toxicity despite the lack of intensity-modulated radiotherapy technique in our institution during the period of study.

Abstract
Vitamin K antagonists (VKA) are difficult to use because of a narrow therapeutic index and of a marked inter- and intra-individual variability among patients in the required dosage. This drug may interact with many other drugs and same with certain food compounds. We report the case of potential interaction between soy lecithin and Vitamin K antagonists in a 46 years-old woman. Subtherapeutic INR values were detected despite the increase gradually in dose and replacing acenocoumarol by fluindione. An enquiry of pharmacovigilance was conducted found the consumption of soy lecithin capsules. Fifteen days after its stopping, the INR values have really increased. Clinicians should think to the possibility of interaction between oral anticoagulants and food supplement that is increasingly used.

Abstract
Sjögren syndrome is uncommon in children and occurs most often in association with autoimmune diseases (secondary Sjögren syndrome). We describe the clinical and biological features of a 7-year-old girl with primary Sjögren syndrome revealed by recurrent parotiditis. CASE REPORT A 7-year-old girl was referred for investigation of multiple episodes of parotid swelling since age 4 years, without systemic symptoms. The examination was unremarkable except for enlarged and painless parotid glands. Laboratory investigations and labial salivary gland biopsy revealed Sjögren syndrome without associated disease. Hydroxychloroquine was prescribed with clinical improvement. CONCLUSION Recurrent parotiditis in children is an uncommon condition. The onset of parotid swelling at 5 years or over deserves screening for disimmune disorders, sarcoidosis, or Sjögren syndrome. Diagnosis of Sjögren syndrome is based on diagnostic criteria.

Abstract
INTRODUCTION Ectopic cervical thymus (ECT) is a rare embryological abnormality in children. It can be revealed by a compressive neck mass mistaken for a malignant tumor. Through a new case of ECT, we review the embryopathogenesis, diagnostic difficulties and therapeutic features. CLINICAL OBSERVATION A 19-month-old girl presented a right cervical mass that quickly increased in size, causing intermittent dyspnea. The physical examination objectified a 6-cm, soft and compressible, painless right cervical tumefaction, extending from the mastoid area to the ipsilateral supraclavicular fossa. The diagnosis suggested based on CT was a cervicomediastinal cystic lymphangioma. The diagnoses discussed based on MRI were a collection of necrotic lymphadenopathy, rhabdomyosarcoma or neurofibroma debris. The mass was surgically excised through a laterocervical incision. A whitish multilobular tissular mass was found, adherent to the neurovascular axis of the neck. Pathological examination concluded in normal ectopic thymus tissue. The postoperative course was uneventful. CONCLUSION Although ECT is a rare benign anomaly, it should be considered as a possible cause of a neck mass in children. Surgery is the curative treatment. Before surgery, the presence of a mediastinal thymus must be confirmed to avoid the risk of a total thymectomy in children. MRI is helpful in delineating thymic ectopia compared to the mediastinal thymus.

Abstract
INTRODUCTION Parathyromatosis is a rare cause of recurrent hyperparathyroidism. It results from hyperfunctioning parathyroid tissue scattered throughout the thyroid bed region. CASE REPORT A 51-year-old man with a history of parathyroidectomy, presented 18 years later with recurrent primary hyperparathyroidism. Surgical exploration identified a single parathyroid gland. The act was completed by a central compartment dissection and ipsilateral lobectomy. The patient was free of recurrence after a one-year follow-up. CONCLUSION Parathyromatosis a rare cause of recurrent hyperparathyroidism. Its management is challenging. Extensive surgery is required with clearance of the central neck compartment and homolateral lobectomy. Medical therapy could be used to decrease parathormone level in recurrent parathyromatosis.

Abstract
BACKGROUND Idiopathic facial palsy is the most common cause of facial nerve palsy in children. Controversy exists regarding treatment options. The objectives of this study were to review the epidemiological and clinical characteristics as well as the outcome of idiopathic facial palsy in children to suggest appropriate treatment. PATIENTS AND METHODS A retrospective study was conducted on children with a diagnosis of idiopathic facial palsy from 2007 to 2012. RESULTS A total of 37 cases (13 males, 24 females) with a mean age of 13.9 years were included in this analysis. The mean duration between onset of Bell's palsy and consultation was 3 days. Of these patients, 78.3% had moderately severe (grade IV) or severe paralysis (grade V on the House and Brackmann grading). Twenty-seven patients were treated in an outpatient context, three patients were hospitalized, and seven patients were treated as outpatients and subsequently hospitalized. All patients received corticosteroids. Eight of them also received antiviral treatment. The complete recovery rate was 94.6% (35/37). The duration of complete recovery was 7.4 weeks. DISCUSSION Children with idiopathic facial palsy have a very good prognosis. The complete recovery rate exceeds 90%. However, controversy exists regarding treatment options. High-quality studies have been conducted on adult populations. Medical treatment based on corticosteroids alone or combined with antiviral treatment is certainly effective in improving facial function outcomes in adults. In children, the recommendation for prescription of steroids and antiviral drugs based on adult treatment appears to be justified. CONCLUSION Randomized controlled trials in the pediatric population are recommended to define a strategy for management of idiopathic facial paralysis.

Abstract
INTRODUCTION Endoscopic sinus surgery has become the treatment of choice in the surgical management of patients with nasal polyposis. The aim of our study is to identify the role of some epidemiological, clinical and therapeutic factors in recurrence after surgery of nasal polyposis. MATERIALS AND METHODS We conducted a retrospective study over a period of 11 years (between 2000 and 2010) including 184 patients operated for nasal polyposis after failure of prolonged medical treatment. We evaluated the impact of epidemiological and clinical factors (age, sex, asthma, Widal disease, allergy and stage of nasal polyposis at the time of surgery) and treatment (surgical technique, observance of postoperative topical steroids ) on postoperative recurrence. RESULTS Nasal polyposis recurred in 26.6% of patients after an average period of 23 months. Widal disease, asthma and bad observance of the intranasal steroid therapy were significantly associated with postoperative recurrence in the univariate analysis. In multivariate analysis the bad observance of the intranasal steroid therapy was the only factor significantly associated with recurrence. CONCLUSION Postoperative steroids prescribed routinely in our practice can effectively prevent recurrence after endonasal surgery and this result was found in both univariate and multivariate analysis.

Abstract
Low-grade sinonasal adenocarcinomas are uncommon and recently described entities. Its histologic diagnosis is challenging. This tumour is characterized by a tendency to local invasion, and rare distant metastases. Well treated, the prognosis is excellent. We describe a case of low-grade nasal cavity adenocarcinoma and discuss the anatomoclinical, therapeutic and evolutionary characteristics of this malignant tumour. A 54-year-old female patient presented with a 10 years history of right-sided nasal obstruction and recurrent epistaxis. On examination the patient had a large, firm mass in the right nasal cavity. Endoscopic sinonasal surgery was performed. The lesion was found to originate from the posteriolateral wall of the right nasal cavity. Histopathology analysis identified a low-grade sinonasal adenocarcinoma. Upon follow-up 4 years after surgery, the patient exhibited no clinical evidence of recurrence. Low-grade sinonasal adenocarcinomas are poorly defined neoplasms, accounting for 4 to 20% of all sinonasal malignancies. The nasal cavity is the most frequently involved site. Low-grade sinonasal adenocarcinomas pose a diagnostic challenge for the pathologist because they must be distinguished from benign tumours, especially adenomas. The primary treatment of sinonasal adenocarcinoma is complete surgical excision.

Abstract
Neuroendocrine carcinoma of the head and neck is a rare entity. The parotid gland is the most commonly affected site. A nasopharyngeal site has not been previously described. We report a 35-year-old patient who consulted for tinnitus and nasal obstruction. The assessment found a nasopharyngeal tumour T4N0M0. The patient underwent 6 cycles of chemotherapy based on VP16 and cisplatin, followed by radiotherapy at a dose of 70 Gy to the nasopharynx and 50 Gy to the neck. The evolution was marked by clinical improvement and radiological stability. Six months after the end of treatment, the patient had a local and meningeal relapse. He received palliative care. He died 19 months after the end of treatment.

Abstract
PURPOSE To compare therapeutic results of nasopharyngeal carcinoma between adults and children. PATIENTS AND METHODS Three hundred and seventy seven patients with nasopharyngeal carcinoma received a radiotherapy between 1993 and 2007. Sixty-nine of them were 20years old or less. Two hundred and sixty eight patients received a chemotherapy (neoadjuvant or concomitant). RESULTS Overall survival and disease-free survival at 5 years were 67 % and 59.4 % in all patients, respectively. Overall survival rates at 5 years in children and adults were 66 % and 64 %, respectively (P=0.17), disease-free survival rates at 5 years were 66 % and 57 %, respectively (P=0.17). Local failures occurred more frequently in adults than in children (1.4 % versus 14 %). However, metastatic events were frequently seen in children. Late toxicities were important in children, xerostomia was the most common one. CONCLUSION Despite locally advanced disease in children, therapeutic results were better than in adults but not statistically significant.

Abstract
The subdiaphragmatic venous drainage of the embryo is provided by the two caudal cardinal veins to which is added the subcardinal vein system, draining the mesonephros, the perispinal supracardinal veins and the umbilical and vitelline venous system. The anastomosis of certain segments of the embryonic venous structures and the disappearance of others are at the origin of the inferior vena cava. Since the 19th century, three-dimensional reconstruction of solid models from histological sections were developed. At present, the development of computerized three-dimensional reconstruction techniques allowed to operate a multitude of techniques of image processing and modeling in space. Three-dimensional reconstruction is a tool for teaching and research very useful in embryological studies because of the obvious difficulty of dissection and the necessity of introducing time as the fourth dimension in the study of organogenesis. This method represents a promising alternative compared to previous three-dimensional reconstruction techniques including Born technique. The aim of our work was to create a three-dimensional computer reconstruction of the retrohepatic segment of the inferior vena cava of a 20mm embryo from the embryo collection of Saints-Pères institute of anatomy (Paris Descartes university, Paris, France) to specify the path relative to the liver and initiate a series of computerized three-dimensional reconstruction that will follow the evolution of this segment of the inferior vena cava and this in a pedagogical and morphological research introducing the time as the fourth dimension.

Abstract
INTRODUCTION Peritonsillar abscess is generally seen as a complication of acute tonsillitis in young subjects. It may, however, in rare cases reveal a malignant tumor of the tonsil: most often squamous cell carcinoma or, more rarely, lymphoma. We report a rare case of tonsillar lymphoma revealed by a peritonsillar abscess. CASE REPORT A 66-year-old woman, without history of recurrent tonsillitis, was admitted for right peritonsillar abscess with fever. She underwent incision-drainage of the abscess with 10 days' intravenous antibiotics. As tonsillar hypertrophy persisted, tonsillectomy was performed; histology with immunohistochemical examination found tonsillar lymphoma. DISCUSSION/CONCLUSION Possible tumoral etiology should be considered in any peritonsillar abscess occurring in an atypical subject. Acute-stage tonsillectomy enables early diagnosis.

Abstract
UNLABELLED To investigate the level of genetic differentiation and diversity among Pyrenophora teres isolate populations originating from different agro-ecological areas of Syria and Tunisia and to determine the potential of AFLP profiling in genotyping Pyrenophora teres f. teres. In this study, AFLP markers have been employed to identify patterns of population structure in 20 Pyrenophora teres f. teres populations from Syria and Tunisia. Ninety-four isolates were studied by the use of a protocol that involved stringent PCR amplification of fragments derived from digestion of genomic DNA with restriction enzymes EcoRI and MesI. Based on 401 amplified polymorphic DNA markers (AFLP), variance analyses indicated that most of the variation was partitioned within rather than between populations. Genotypic diversity (GD) was high for populations from Rihane, local landraces and different agro-ecological zones (GD = 0·75-0·86). There was high genetic differentiation among pathogen populations from different host populations in Syria (Gst = 0·31, ht = 0·190) and Tunisia (Gst = 0·39, ht = 0·263), which may be partly explained by the low gene flow around the areas sampled. A phenetic tree revealed three groups with high bootstrap values (55, 68, 76) and reflected the grouping of isolates based on host, or agro-ecological areas. AFLP profiling is an effective method for typing the genetically diverse pathogen Pyrenophora teres f. teres. SIGNIFICANCE AND IMPACT OF THE STUDY The study represents a comparative analysis of the genetic diversity in P. teres isolates from two countries spanning two continents and also shows that several distinct P. teres genotypes may be found in a given environment. The implications of these findings for Pyrenophora teres f. teres evolutionary potential and net blotch-resistance breeding in Syria and Tunisia were also discussed.

Abstract
A survey on the occurrence of ochratoxin A (OTA) in wines and beers produced in Tunisia was carried out. Wines and beers were analysed using immunoaffinity column clean-up and high-performance liquid chromatography coupled to a fluorometric detector. OTA was detected in 29 wine samples, with an incidence of contamination of 85%. The OTA levels ranged between 0.09 and 1.5 µg/L. Neither of the studied samples showed levels above the European regulatory limit (2 µg/L). OTA was detected in 17 beer samples with an incidence of contamination of 45%. The OTA levels ranged between 0.04 and 0.35 µg/L. The OTA dietary intake by the consumption of wine and beer may be considered as negligible. The obtained results showed high incidence of OTA in Tunisian wines and beers; however, there are no toxicological risks for Tunisian consumers through their consumption of such processed products using cereals and grapes.

Abstract
INTRODUCTION Inhalation of foreign body in children is a serious accident that may compromise the vital prognosis of the child. The diagnostic was difficult in the absence of a recognizable penetration syndrome. Bronchoscopy is still recommended as the appropriate diagnostic and treatment of foreign bodies. The purpose of this study was to analyze the diagnostic and the treatment result of bronchoscopy and discuss its indications. MATERIAL AND METHODS [corrected] A retrospective study analyzing data related to 223 children undergoing bronchoscopy due to suspicion of foreign body aspiration over a period of 10 years (2000-2009). The average age of the children was 29 months (range: one month-13 years). Approximately, two thirds of these patients were boys. The penetration syndrome was reported in 79.8% of cases. RESULTS During bronchoscopy, the foreign body was confirmed only in 57.4%. Foreign bodies were found in the bronchus in 79.7% of cases. Among the foreign bodies, 78.1% were of vegetal origin. The average time of stay of the foreign body was of 16.1 days. Penetration syndrome and abnormal physical exam were the most sensitive parameters (79.7% and 82.8%, respectively) but with low specificity (24.2% and 35.8%, respectively). The combination of clinical and radiological signs suggestive of foreign body was the most specific sign (74.7%). Similarly, we found a statistically significant correlation between positive bronchoscopy and simultaneous suggestive clinical and radiological signs (P=0.03). The multivariate study showed that predictors factors of positivity of the bronchoscopy were: abnormal physical exam (P=0.016), abnormal radiological exam (P=0.003) and type of indication (P=0.005). DISCUSSION The diagnosis of laryngotracheobronchial foreign body recures an array of arguments. It is suspected on the clinical interview specially penetration syndrome and on the clinical and radiological presentation. Any suspicion should lead to a bronchoscopy.
