Abstract
Video quality assessment is a challenging problem having a critical significance in the context of medical imaging. For instance, in laparoscopic surgery, the acquired video data suffers from different kinds of distortion that not only hinder surgery performance but also affect the execution of subsequent tasks in surgical navigation and robotic surgeries. For this reason, we propose in this paper neural network-based approaches for distortion classification as well as quality prediction. More precisely, a Residual Network (ResNet) based approach is firstly developed for simultaneous ranking and classification task. Then, this architecture is extended to make it appropriate for the quality prediction task by using an additional Fully Connected Neural Network (FCNN). To train the overall architecture (ResNet and FCNN models), transfer learning and end-to-end learning approaches are investigated. Experimental results, carried out on a new laparoscopic video quality database, have shown the efficiency of the proposed methods compared to recent conventional and deep learning based approaches.

Abstract
Growing teratoma syndrome is a rare condition among patients with nonseminomatous germ cell tumors who present with enlarging metastatic masses during appropriate systemic chemotherapy and normalized serum markers. Retroperitoneal residual masses are a common finding after chemotherapy for the nonseminomatous tumors of the testis. These might contain mature teratoma, fibrotic tissue, or tumor. Mature teratoma, which is unresponsive to chemotherapy, might result from evolution of a malignant lesion during treatment or it might represent a metastasis from a focus of mature teratoma in the primary testicular tumor. This article reviews a case of a growing teratoma syndrome.

Abstract
INTRODUCTION The association between malignant tumors and HIV infection is well known. We report a rare case of gingival granulocytic sarcoma (GS) associated to HIV infection. OBSERVATION A 31 year-old HIV patient consulted for left maxillary tumefaction. His viral load was high (40,112 copies/ml) and CD4 count low (287cells/mm(3)). After biopsy-exeresis, histology and an immunohistochemical study confirmed the diagnosis of GS. Chemotherapy similar to that of acute myeloid leukemia (AML) completed the treatment. The remission was complete at 5 years. DISCUSSION Only one case of intra-oral GS associated to HIV infection has been reported so far. The clinical and radiological presentation is unspecific. Histology proves the diagnosis. The treatment is comparable to that of AML. The prognosis is usually bad.

Abstract
Dysembryoplastic neuroepithelial tumour is an uncommon lesion of the brain characterised by a heterogeneous population of neurons, astrocytes and oligodendroglia-like cells. Most patients are young adults with a long history of drug-resistant seizures. We report a case of a 31 year-old woman with a history of severe epileptic attacks. Cerebral imaging showed a left temporal tumour measuring 4 cm in its greater dimension. After surgical intervention, histopathological examination showed a tumoural proliferation with both glial and neuronal components that was confirmed by immunohistochemistry. We also describe the spectrum of dysembryoplastic neuroepithelial tumours and their histological features.

Abstract
Primary cardiac sarcoma is a rare tumor with a poor prognosis. We report 3 cases with a review of literature about this disease. There were 2 males and 1 woman. The main symptoms were thoracic pain. The clinical features were various and the thoracic ultra sonography exam allowed the diagnosis in the 3 cases. All patients had surgical remove of their cardiac tumor followed by chemotherapy. All of them died within 13 to 36 months after the diagnosis. Primary cardiac sarcoma has a poor prognosis with a mean survival less than 12 months.

Abstract
The objective of this study was to identify the anatomical-clinical aspects and determine the prognostic factors for breast cancer in the central region of Tunisia. This retrospective study involved 729 patients suffering from breast cancer, proven either by histology or cytology, diagnosed and treated between January 1990 and June 1998 at the F. Hached University Hospital in Sousse, Tunisia. The patients' average age was 50 years (ranging from 22-91). The average size of the cancer at the time of diagnosis was 49.1 mm; 90% were invasive duct carcinoma with high histo-prognostic SBR grade (level II-III: 86%). The overall survival rate was 50.5% after five years, and 50% after seven years. Using univariate analysis, significant predictive value was found with the following factors: tumor size, the clinical ganglionic level, metastases at diagnosis, the number of nodes invaded, nodal capsular rupture and lymphatic embolism, SBR grade and the delay in seeking consultation. The multivariate analysis (Cox model) isolated two prognostic factors: the initial size of the tumor (p = 0.001) and metastases at the time of diagnosis (p = 0.01). The study's results indicated that breast cancer prognosis in Tunisia remains poor primarily due to late diagnosis.
