Method: Lung cancer is commonly associated with malnutrition. This leads to a worse prognosis as well as more complications of the disease Tools and Methods: Prospective study about patients treated with lung cancer from July to September 2019 in the pulmonary department of Hedi Chaker of Sfax. Malnutrition is defined when Body Mass Index (BMI) 10%. We uses two scores: the MNA (Mini Nutritional Assessment) as well as the PG-SGA (Patient Generated Subjective Global Assessment) Method: We included 30 patients, mean age was 58 years. Twenty seven patients were active smokers with intoxication of 54 pack year. The adenocarcinoma was most frequent (13 patients), the squamous cell carcinoma (7 patients) and small cell carcinoma (5 patients). Two third of the population were in stage IV. Twenty three cases received chemotherapy based on platinum salt and another molecule (third generation). The diet is composed of 3 meals in 23 cases, it lasts about 15 to 30 minutes in 23 cases also. Eight patients do not eat a snack between meals. The causes of diet problems were: dysphagia (5 cases), changes in taste (18 cases), nausea and vomiting (11 cases), loss of appetite (17 cases), mucositis (10 cases), depression (7 cases). The mal nutrition was noted in 13 patients, it was severe in 8 cases. The MNA was normal in 4 cases, risk of malnutrition in 14 cases and poor nutritional status in 12 cases. According to PG-SGA 26 patients require serious intervention to improve the nutritional status. Malnutrition was more common in active smokers (p=0,005) and at stage IV of the disease. Conclusion: Nutritional assessment should be establishd for all patients with lung cancer for better prognosis and less complications.

RÉSUMÉ. Les requêtes médicales sont souvent étiquetées par le type du modèle de recherche estimé donnant les meilleures performances selon des experts du domaine. Dans un travail pré- cédent, nous avons proposé d'automatiser cette tâche d'étiquetage (de classification) manuelle. Dans ce papier, nous proposons une nouvelle approche de classification qui apprend automati- quement à associer à chaque requête l'étiquette du modèle de recherche le plus adéquat. Plus précisément, nous générons un ensemble de règles d'association combinant certaines carac- téristiques des requêtes et les étiquettes des modèles de recherche. Ensuite, les requêtes dont les règles d'association remplissent les conditions seront étiquetées par les règles. Les autres, peuvent être automatiquement étiquetées en se référant à certaines caractéristiques spécifiques.

The thymus is a lymphoid organ located in the antero-superior mediastinum and composed of heterogeneous admixture of lymphoid and epithelial elements. Thymic tumors are dominated by thymoma; lymhomas are uncommon involving the gland secondary to adenopathies. Primary thymic lymphomas are exceptional. We report a 25-year-old man referred to us because of chest pain and irritating cough since 2 months. Physical examination was normal and no lymph nodes were palpable. Chest radiography showed an anterior mediastinal mass. Computed tomography (CT) examination of the chest revealed a homogeneous tissular mass occupying the anterior mediastinum in its upper and medium stage, extending to the infundibulum without lymph node enlargement. Thymectomy and wedge were performed via a median sternotomy. Pathologic diagnosis was nodular sclerosis Hodgkin's disease of the thymus. The patient received 6 cycles of ABVD (Adriamycin [doxorubicin], bleomycin, vinblastin and dacarbazine) and mediastinal radiotherapy. Currently, tow years after diagnosis, he is well and free of disease. Primary thymic Hodgkin's lymphoma is a rare entity which should be included in the differential diagnosis of anterior mediastinal mass especially in young patients.
