Post Traumatic Hemobilia: Three Case Reports  [PDF]
Hicham Jalal, Hana Elmansouri, Sofia El Fakir, Leila Berghalout, I. Zouita, Najat Cherif Idrissi El Ganouni, Youssef Narjiss, Khalid Rabbani
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105102
Abstract:
The authors report three cases of post-traumatic hemobilia. Hemobilia complicates about 0.5% to 2% of liver injuries. The diagnosis can be difficult because of its possible delay of appearance. The ultrasound and CT scan performed urgently are of great help in both positive diagnosis and monitoring of this pathology. Once the diagnosis is made—immediatly or a while after the trauma—a diagnostic and therapeutic arteriography must be carried out quickly.
Legionaires’ disease: Modalities, diagnosis and therapeutic
Bouchra Oumokhtar,Samira El Fakir
Technologies de Laboratoire , 2009,
Abstract: Infection with Legionella spp. is an important cause of community and hospital acquired pneumonia, occurring both sporadically and in outbreaks. The Legionaires’ disease affects primarily adults and more specifically fragile people such as elderly adult, patients affected by chronic respiratory diseases, diabetics and immunodeficient people. The contamination with legionellosis is mainly through respiratory tract, inhalation of contaminated water diffused in air. It is mainly transmitted by humidifying cooling systems and water network. The legionellosis is expressed by grip profile accompanied with fever and coughing. Others symptoms such as muscular pain, anorexia, digestive and neurological disorder might occur. The diagnosis of legionellosis is achieved by investigating the urinary antigen. But this test detects only Legionella pneumophila serogoup 1. The PCR allows fast diagnosis. However, this technique is not yet normalized. The legionellosis is mostly treated using suitable antibiotherapy. Macrolides and fluoroquinolones are the most widely used drugs in treatment.This review summarizes the available information regarding the microbiology, clinical presentation, diagnosis and treatment of Legionaires’ disease.
Recognition of Tifinaghe Characters Using a Multilayer Neural Network
Rachid EL Ayachi,Mohamed Fakir,Belaid Bouikhalene
International Journal of Image Processing , 2011,
Abstract: In this paper, we present an off line Tifinaghe characters recognition system. Texts are scannedusing a flatbed scanner. Digitized text are normalised, noise is reduced using a median filter,baseline skew is corrected by the use of the Hough transform, and text is segmented into line andlines into words. Features are extracted using the Walsh Transformation. Finally characters arerecognized by a multilayer neural network.
Microbial analysis of raw ground beef marketed in Fez (Morocco)
Oumokhtar bouchra,Berrada Halima,Ameur Najia,El Fakir Samira
Technologies de Laboratoire , 2008,
Abstract: The ground meat is highly perishable product. This foodstuff constitutes a potential risk for the consumer since it is mostly consumed while insufficiently cooked. The aim of the present study was to evaluate the bacterial quality of ground beef marketed in Fes. Forty samples of ground meat were collected randomly from butcheries during three months in Fez (Morocco). The samples were analyzed for the presence and counts of various bacteria. Results indicated that faecal coliforms and Escherichia coli were particularly high in all the samples analysed. The coagulase-positive Staphylococcus and anaerobic sulphite-reducing charges were not homogeneous. When Salmonella, and Shigella were detected respectively in 17,5 % and 2,5% of the ground beef samples. The ground beef samples contained 80% of bacteria above the maximum limits established by the Moroccan regulatory standards. These high levels of microbial contamination and occurrence of pathogenic bacteria reflect the poor hygienic quality of ground beef production and transport conditions.
Comparison of Two Feature Extraction Method Based on the Raw Form and Skeleton for MNIST Database
Kamal Moro,Mohammed Fakir,Badr Dine El Kessab,Belaid Bouikhalene
International Journal of Computer Science Research and Application , 2012,
Abstract: In this paper, we present a comparison of two few extraction methods based on the raw form and the skeleton. The experimental results show the benefit of using these methods compared with other conventional approaches; the findings have been applied on the MNIST database. The paper presents the evaluation work for the comparison of the two methods and provides conclusions based on the study outcomes.
Segmentation and Recognition of Arabic Printed Script
Fakir Mohamed Fakir
IAES International Journal of Artificial Intelligence (IJ-AI) , 2013, DOI: 10.11591/ij-ai.v2i1.1236
Abstract: In this work we present a method for the recognition of Arabic printed script. The major problem of the automatic reading of cursive writing is a segmentation of script to isolate characters. The recognition process consists of four phases: Preprocessing, segmentation, feature extraction and the recognition. In the preprocessing, the image is scanned and smoothed. The correction of skew lines is done by using Hough transform . In the second phase, the text is segmented into lines, words or parts of words and each word into characters based on the principle of projection of the histogram. Features such as: density, profile, Hu moments and histogram are used to classifier the characters based on the Neural network.

Diagnostic Pathology , 2013, DOI: 10.1186/1746-1596-8-4
Abstract: The virtual slides’ for this article can be found here: http://www.diagnosticpathology.diagnomx.eu/vs/8956897238238989 webciteMetastatic tumors to the gallbladder are uncommon. The most common metastatic tumors to the gallbladder are metastatic melanomas and metastatic carcinomas from stomach, pancreas, ovary, bile ducts, colon and breast [1]. Metastatic renal cell carcinoma in the gallbladder is extremely rare, with reported frequencies of less than 0.6% in large autopsy reviews [2]. Renal cell carcinoma is a rare tumor accounting for 3% of all malignancies in adults and 85% of primary renal tumors. However, this tumor has a great propensity for metastasizing synchronously or metachronously to various anatomic sites [3]. We report a case of intraluminal polypoid metastasis of clear cell renal cell carcinoma in gallbladder mimicking gallbladder polyp and revealing the renal carcinoma and reviewed the reported 40 cases. The clinico-pathologic features and differential diagnosis are discussed.A 55-year-old woman presented with severe right hypochondrium pain, with weight loss and alteration of her general condition, lasting for 6 months. She showed no urological signs, especially no hematuria, no pain, and no flank mass. She had no past history in particular. Neither physical examination nor laboratory examination revealed any significant findings. Abdominal ultrasonography showed a 2.6 cm diameter intraluminal polypoid hyperechoic mass in the gallbladder. Color Doppler ultrasonography examination demonstrated vessels in the mid-portion of the mass. Computed tomography scan confirmed the presence of a gallbladder tumor that appeared as an enhancing pedunculated tumor within the gallbladder, without thickening of the gallbladder wall. The tumor seemed to be attached to the edge of the liver with no macroscopic extension to the liver parenchyma (Figure 1). Furthermore, TDM scan showed a cortical fleshy nodule of the right kidney, measuring 2.2 cm, with no involvement of
Gravity-Wave Watching
Redouane Fakir
Physics , 1993, DOI: 10.1086/174040
Abstract: It is suggested that gravity waves could, in several cases, be detected by means of already (or shortly to be) available technology, independently of current efforts of detection. The present is a follow-up on a recently suggested detection strategy based on gravity-wave-induced deviations of null geodesics. The new development is that a way was found to probe the waves close to the source, where they are several orders of magnitude larger than on the Earth. The effect translates into apparent shifts in stellar angular positions that could be as high as $10^{-7}$ arcsec, which is just about the present theoretical limit of detectability. (Calculation improved; results unchanged.)
Early Direct Detection of Gravity Waves
Redouane Fakir
Physics , 1993,
Abstract: Recently, the possibility has emerged of an early detection of astrophysical gravity waves. In certain astronomical configurations, and through a new light-deflection effect, gravity waves can cause apparent shifts in stellar angular positions as large as $10^{-7}arcsec$. In these same configurations, the magnitude of the gravity-wave-induced time-delay effect can exceed $10^{-14}$. Both these figures lie just at present-day theoretical limits of detectability. For instance, cases are described where the very faint neutron-star gravity waves could soon become detectable. The detection meant here involves direct observations of the very wave-forms.
A Macroscopic Gravity Wave Effect
Redouane Fakir
Physics , 1996,
Abstract: Gravitational waves, although generally associated with extremely microscopic effects, can displace by hundreds of kilometers the pulsar interstellar scintillation patterns that bathe the Earth. The combination of the pulsar and the interstellar medium acts as a kiloparsec-long, nature-provided gravity wave amplifier. We show how an effective scheme for the detection of periodic gravity waves can be constructed based on this effect. This approach to detection does not require the development of new, ad hoc technology, but the optimization of existing observational techniques in a few different fields of astronomy. Part of the scheme is a new, purely numerical detection technique that can also be used in the data processing of other projects of periodic gravity wave detection.
