To define, the prevalence and risk factors of hepatitis C virus (HCV) a prospective and multicentre study was performed in 235 patients undergoing haemodialysis, the anti-HCV antibodies were evaluated using an immuno-enzymatic method (wellcozyme anti-HCV). The following parameters were obtained for all patients: time on haemodialysis, blood transfusion,(More)
Currently, research is focused on selective encryption to protect movies against attacks transmitted over a public network. This choice is taken to ensure the security of compressed data without adding an important supplemental computational time for the encryption. So the encryption module is inserted into the video compression chain. In this paper we(More)
Glanzmann thrombasthenia (TG) is a congenital platelet function disorder characterized by frequent and occasionally severe bleeding events. Treatment is based on platelet transfusion at the time of bleeding. We report a case of GT revealed in the neonatal period, a severe hemorrhagic syndrome refractory to transfusions, treated at the age of 6 years.(More)
From years ago, encryption became a necessity to transmit data securely. Like message written, fixed images or movies should be encrypted also while transmitted over a public channel. Currently, the literature is pointed to selective encryption for those types of data against attacks. That's to say, the encryption module is inserted into the chain of video(More)
The concept of data compression in CODECs is based on pixel prediction to avoid redundancy. For the security of data compressed with the H.264/AVC CODEC, researchers are thinking to selective encryption. This paper presents a chaos based encryption method inserted in the H.264/AVC used for video conferencing application. It consists of the encryption of(More)
Lossy video coding can be achieved by using the H.264 Advanced Video Coding. Some methods have been proposed to transform this coder into a lossless one. The hierarchical lossless video coding structure with new intra algorithm prediction was proposed to reach this goal. In this paper we proposed some enhancements of this method to improve the coding(More)
Cavernous malformations are vascular lesions of the central nervous system. They are very rare in childhood. We report the case of sporadic cavernous cerebral angioma in a 1-year-old girl without pathologic antecedents revealed by a partial seizure. With this case and a review of the literature, we show the clinical and therapeutic characteristics of(More)
OBJECTIVES To reappraise the respective involvement of small- and large-fiber damage in carpal tunnel syndrome (CTS) and to determine the diagnostic sensitivity of autonomic tests compared to conventional nerve conduction study (NCS). METHODS Thirty-two manual workers complaining of at least unilateral CTS were enrolled. They underwent clinical interview(More)
