Active clinical trials for "Acute Disease"

The purpose of this study is to determine the maximum tolerable dose of irinotecan in combination with etoposide, cytarabine for refractory or relapsed acute leukemia in pediatric patient.

This study focuses on the use of contrast enhanced low-dose CT imaging as a modality to differentiate between uncomplicated and complicated acute appendicitis. Differentiation between the two forms of acute appendicitis is important because according to recent studies their treatment differs. Complicated forms are still treated operatively, while uncomplicated forms can be treated conservatively with antibiotics. In the initial phase of the study, several optimized CT protocols will be created with a phantom model. The two best performing models will be selected for the second phase of the study, in which patients presenting with suspected acute appendicitis will be imaged with the two protocols. All patients participating in the study will be treated operatively, primarily with a laparoscopic appendectomy. Thus histological confirmation for the diagnosis can be achieved and compared with the CT images. The goal of this study is to optimize a well-performing low-dose CT imaging protocol to use in the diagnosis of uncomplicated acute appendicitis.

Acute leukemias are a heterogeneous group of malignancies characterized by the abnormal proliferation of a cell clone in the bone marrow, having as origin lymphocytic or myeloid lineage. The repertoire of mutations that determine the leukemic transformation, complex and variable depending on the tumor type and progression of the disease, combined in the same cell of balanced and unbalanced chromosomal aberrations, point mutations and epigenetic abnormalities. The project presented here is part of a comprehensive approach to diagnosis of hematologic malignancies of children. Using comparative genomic hybridization on microarray (or array- CGH) and transcriptome analysis by microarray, two innovative techniques for a comprehensive analysis of the genome and transcriptome , offer new perspectives identifying molecular defects . These techniques provide new elements in the identification of acute leukemia at diagnosis may identify new prognostic factors to optimize the care of patients. This project involves both the Department of Medical Genetics (Prof. N. LEVY ) regarding the identification of genomic abnormalities associated with childhood leukemia , the Laboratory of Hematology of the Hospital de la Timone ( Prof. Pierre Morange ) in terms of the phenotypic characterization of tumor cells, and the Onco - Hematology Pediatric Department (Prof. Michel Gerard ) which provides diagnosis, treatment , monitoring and the bone marrow of children with hematologic malignancies . The following project is mainly focused on the identification of genomic abnormalities (deletions and duplications) and abnormalities in gene expression to identify a genetic profile ensuring a better classification within the different groups risk . The project we propose is centered on the identification of genomic abnormalities , changing the number of copies of certain regions of the genome or determining loss of heterozygosity , and the identification of changes in the level of gene expression by using two analytical techniques, comparative genomic hybridization on microarray (or array- CGH) and expression studies with microarrays . The data generated will , for the identification of " molecular signatures " , the classification of patients according to prognosis , variations in treatment response and survival. The originality of this project lies in the use of these new tools in the diagnosis of hematological malignancies in children. This pilot study will be conducted with commercial Affymetrix , will develop the chips ' processing' , dedicated , enriched probes corresponding to genes involved in leukemogenesis , with high discriminatory power in identifying these signatures. The data published in the specialized literature from the study of large series of patients show that microarrays provide important information for the diagnosis and therapeutic management of patients. It is for this reason that in the end we hope to integrate these analyzes in routine diagnosis to complement other analyzes ( phenotyping , identification of fusion genes and sequencing) in order to further characterize the abnormal cells leukemia and establish an " identity card of leukemia .

The purpose of the study is to implement and evaluate a novel triage algorithm for risk stratification of acutely admitted patients in the Emergency Department.

To investigate the changes of angle structure and intraocular pressure after argon laser peripheral iridoplasty in patients with acute angle closure glaucoma patients whose intraocular pressure could not be controlled by drug therapy during the major attack period.

This study evaluates the impact of a new and comprehensive school-based health program implemented in Lusaka, Zambia.

Short Post-operative Antibacterial Therapy in Complicated Appendicitis: Oral Versus Intravenous is a prospective randomized controlled trial comparing 24 hour intravenous antibacterial therapy to 24 hour oral antibacterial therapy after surgery in complicated appendicitis.

The aims are to identify predictive indicators of hospitalized elderly medical patients' need for rehabilitation and to validate (known group validity) the Chair Stand Test

This study evaluates the intraabdominal abscess rate after laparoscopic appendectomy in complicated acute appendicitis performing irrigation of the abdominal cavity or only suction without lavage.

The aim of this study is to reduce the postoperative hospital stay, without increasing morbidity and mortality postoperative, expressed in terms of rate of complications and readmissions.
