Abstract
Background Computational analysis of routine electroencephalogram (rEEG) could improve the accuracy of epilepsy diagnosis. We aim to systematically assess the diagnostic performances of computed biomarkers for epilepsy in individuals undergoing rEEG. Methods We searched MEDLINE, EMBASE, EBM reviews, IEEE Explore and the grey literature for studies published between January 1961 and December 2022. We included studies reporting a computational method to diagnose epilepsy based on rEEG without relying on the identification of interictal epileptiform discharges or seizures. Diagnosis of epilepsy as per a treating physician was the reference standard. We assessed the risk of bias using an adapted QUADAS-2 tool. Results We screened 10 166 studies, and 37 were included. The sample size ranged from 8 to 192 (mean=54). The computed biomarkers were based on linear (43%), non-linear (27%), connectivity (38%), and convolutional neural networks (10%) models. The risk of bias was high or unclear in all studies, more commonly from spectrum effect and data leakage. Diagnostic accuracy ranged between 64% and 100%. We observed high methodological heterogeneity, preventing pooling of accuracy measures. Conclusion The current literature provides insufficient evidence to reliably assess the diagnostic yield of computational analysis of rEEG. Significance We provide guidelines regarding patient selection, reference standard, algorithms, and performance validation.

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.
