    Neurofibrome de l’avant bras: à propos d’un cas

    Get PDF
    Les tumeurs des nerfs périphériques sont rares et mal connues. Le diagnostic en est rarement fait avant  l'intervention. Le traitement chirurgical est difficile, et risque d'entrainer des dégâts nerveux irréversibles s'il est mal conduit. Nous rapportons un cas de neurofibrome de l'avant bras dont la symptomatologie est souvent discrète associé à des taches café au lait sur la peau. De ce fait, l'imagerie et l'examen anatomopathologique ont une place importante dans la prise en charge de ces tumeurs.Key words: Neurofibromes, taches café au lait, imagerie, chirurgie, anatomie pathologi

    A Mobile Application with Augmented Reality to Enhance Sinhala Learning Experience for Children

    Augmented Reality has gone from science fiction dream to possible emerging technology in the modern world. This futuristic technology has the ability to blend the real world with digital world. This paper presents an Augmented Reality based mobile solution for children to enhance their Sinhala alphabet learning experience. With this tool, children can interactively learn letters, pronunciation and usage of letters in real world scenarios. Generally, teaching preschool children could be difficult since they only focus on an activity for a short period of time. Therefore this solution mainly focuses on adding fun and entertainment while addressing cognitive skills of the children. This application adds totally new learning experience for its users. A survey done with pre-school children and teachers proved that using Augmented Reality based solution with latest technologies are very helpful for learning things and teaching things efficiently. Most students requested to use the Augmented Reality application repeatedly. Teachers showed high level of enthusiasm and over 85% of the respondents gave extremely positive feedbac

    Thermoplasmonic ssDNA Dynamic Release from Gold Nanoparticles Examined with Advanced Fluorescence Microscopy

    Get PDF
    Plasmon excitation of spherical gold nanoparticles carrying a fluorescent labeled 30 bp dsDNA cargo, with one chain covalently attached through two S–Au bonds to the surface, results in release of the complementary strand as ssDNA that can be examined in situ using high-resolution fluorescence microscopy. The release is dependent on the total energy delivered, but not the rate of delivery, an important property for plasmonic applications in medicine, sensors, and plasmon-induced PCR

    Objectivethe objective was to identify the epidemiological, clinical and the outcome of heart failure (HF) in a Moroccan hospital.MethodA retrospective study using a serie of 294 patients hospitalized in our service from January 2005 to December 2008.ResultsThe HF occupies 14% of hospitalizations. The mean length of stay was 14±3.1 days. The mean age was 58±11.5 years. Men were mostly represented with a ratio H / F=3.5. The main cardiovascular risk factor was smoking (55%) followed by hypertension (40%) and diabetes (35%). Dyspnea was the main symptom reported in 91% of the cases. The clinical presentation was that of left (65%), right (22%) and global(23%) HF. Among electric signs, we found Atrial fibrillation (30%), a Q-wave (58%) and left ventricular hypertrophy (28%). the chest x-ray showed a cardiomegaly (89%) and signs of pulmonary overload (86%). Biology showed electrolyte abnormalities in half of the cases, renal failure (35%) and anemia (28%). In echocardiography, the mean left ventricular ejection fraction (LVEF) was 34.5±5.4%. LVEF was > 45% for 26% of patients. 134 patients underwent a coronary angiography which objectified coronary damage in 84% of the cases. The main causes were ischemic heart disease (42%), valvular heart disease(24%) and hypertension (13%). most used drugs were angiotensin converting enzym inhibitors and diuretics. 21% of patients underwent a mitral valve replacement with mechanical prosthesis. Among patients with coronary artery disease, 33% were revascularized by coronary bypass (21%) and coronary angioplasty (12%). Cardiac resynchronization was performed for 19 patients using implantable automatic defibrillator for 3 of them.Hospital mortality was 10%.ConclusionThe main features of this population is the relatively young age, male predominance, ischemic heart disease as a leading cause and low rate of HF with preserved systolic function

    Current Cytogenetic Abnormalities in Acute Myeloid Leukemia

    Get PDF
    Cytogenetic abnormalities are frequently reported in the literature describing the presence of chromosomal rearrangements in important cases of acute myeloid leukemia (AML); the rate can reach 50–60% of cases of AML. Cytogenetic abnormalities represent an important prognosis factor, their analysis is crucial for AML; cytogenetic study permits to classify prognostic groups and indicate the treatment strategy and helps to improve the outcome of these patients and to increase their chances of cure. Hundreds of uncommon chromosomal aberrations from AML exist. This chapter summarizes chromosomal abnormalities that are common and classifies AML according to the World Health Organization (WHO) classifications from 2008 to 2016; we will discuss briefly gene mutations detected in normal karyotype (NK) AML by cutting-edge next-generation sequencing technology, like FLT3-ITD, nucleophosmin (NPM1), CCAAT/enhancer-binding protein alpha (CEBPA), and other additional mutations
