Acute lower limb ischemia revealing hypo granular acute promyelocytic leukemia.

Introduction: Acute promyelocytic leukemia (AML-M3), classified as acute Myeloid leukemia with PML RARA according to the 5th edition of the World Health Organization classification of haematolymphoid tumors 2022 [1], is marked by abnormal promyelocyte proliferation and is known for high risks of bleeding and thromboembolic complications. We present a case where lower limb ischemia revealed this leukemia in a child.

Case Report: An 11-year-old with minor ankle trauma developed severe lower limb ischemia, leading to the discovery of subtotal femoral artery thrombosis.

Comparative Study of Cerebrospinal Fluid Evaluation in Patients With Acute Leukemia Using the Manual Method and Sysmex XN-1000.

Background Many pathological settings can be provided by the cytological analysis of cerebrospinal fluid (CSF). In our work, we aimed to evaluate the concordance between the analysis using the reference manual method and the analysis using Sysmex XN-1000. Methods In our study, we examined 121 CSF samples.

Development of shelf life-extending packaging for vitamin C syrup based on high-density polyethylene and extracted lignin argan shells.

Biobased packaging is an essential parameter in the pharmaceutical industry. In the present work, bio-composites consisting of high-density polyethylene (HDPE) as a matrix and lignin recovered from argan nut shells as filler were developed to investigate their potential use as packaging materials for vitamin C drugs. The lignin was extracted via alkali and klason processes, and the effects of the extraction method as well as the lignin content on the thermal, morphological, mechanical, and rheological properties of the produced composites, as well as their application for vitamin C packaging, were investigated.

Hemiparesis Revealing a Unique Neurological Hemophagocytic Lymphohistiocytosis in a Patient With Griscelli Syndrome Type 2.

Griscelli syndrome (GS) is a rare genetic disorder that encompasses three different subtypes (GS type 1 (GS1), GS type 2 (GS2), and GS type 3 (GS3)), in which isolated neurological manifestations without immune system implications are typically seen in GS1, while neurological involvements in GS2 should be attributed to the macrophage and lymphocyte invasion of the central nervous system (CNS), under associated hemophagocytic lymphohistiocytosis (HLH). The presence of the clinical, biological, and hematologic features of HLH help explain the neurological defects that GS2 patients unusually present. In our case report, however, we attempt to highlight an uncommon presentation of GS2 involving a hemiparesis, along which we did not have any clinical or biological features of HLH.

Value of hematological parameters for predicting patients with severe coronavirus disease 2019: a real-world cohort from Morocco.

Objective: Coronavirus disease 2019 (COVID-19) is a viral disease caused by severe acute respiratory syndrome coronavirus 2. The clinical manifestations and the evolution of patients with COVID-19 are variable. In addition to respiratory involvement, COVID-19 leads to systemic involvement and can affect the hematopoietic system.

Visceral leishmaniasis associated with macrophage activation syndrome: Case report and literature review.

Background: The combination of visceral leishmaniasis (VL) and macrophage activation syndrome (MAS) makes the diagnosis difficult due to their similar clinical presentation, with a poor prognosis especially since the treatment is still poorly codified.We report the case of a 17-month-old female patient from Berkane, presenting for a 3 months history of anarchic fever with anemic syndrome made up of pallor and hemorrhagic syndrome made up of epistaxis. Physical examination revealed a temperature of 39 ° C, lower limbsedema, paleness of skin and mucous membranes, gingival petechiae, bleached hair, and hepatosplenomegaly.

[A flowchart is always useful: application to the interpretation of the cytobacteriological examination of urine].

The cytobacteriological examination of urine (CBEU) is the most prescribed test in a microbiology laboratory. The objectives of this work were to present our experience in carrying out the CBEU and to share one of the means that we consider very useful in the daily practice of this crucial analysis. This is a 28-month prospective study (March 2016 to June 2018).

[Serum protein electrophoresis: study of 410 electrophoretic profiles].

Serum protein electrophoresis (SPE) is a routine analysis in the daily practice of a medical biology laboratory. This study aimed to analyze the different electrophoretic profiles seen in our current practice. We conducted a cross-sectional study of 410 serum samples collected during the routine analyses in the Laboratory of Biochemistry at the University Hospital Mohammed VI in Oujda.

Comparison between Roche Integra 400 plus and Abbott Architect ci8200 in Alanine aminotransferase assay.

Background: The aim of this work is to present the results of a comparative study between the ALT assay on Integra 400 plus Roche Diagnostic versus Architect ci8200 of Abbott Diagnostic.

Methods: A total of 200 patients hospitalized in the various departments of the university hospital Mohammed VI of Oujda were prospectively tested on two systems: Abbott Architect ci8200 and Roche Integra 400 plus. Both analyzers use the spectrophotometric technique by coupling the transamination reaction to the oxidation-reduction reaction at NAD.

A Rare Case of Non-Secretory Multiple Myeloma: A Case Report and Literature Review.

Non-secretory myeloma (NSM) is a rare form of myeloma. It is defined as monoclonal plasmocytic proliferation of the bone marrow with the same clinical and radiological manifestations of myeloma. However, plasma cells are unable to secrete immunoglobulin (serum and urinary electrophoresis are negative and free light chain measurement is unquantifiable).

Gaucher Disease: An Underdiagnosed Pathology in the Eastern Moroccan Population.

Gaucher disease (GD) is a lysosomal storage disease. It corresponds to a congenital deficit in β-glucocerebrosidase. This pathology should be considered in the presence of unexplained splenomegaly, with or without signs of haemorrhage, skeletal manifestations or hepatomegaly.

[Comparative study of the serum measurement of PTH on Roche Cobas e411 versus the Abbott Architect ci8200].

Parathormone (PTH) is the main hormone of phosphocalcic homeostasis. It is synthesized and secreted by the parathyroid glands. PTH has become a routine test in the medical biology laboratory.

Biocomposites based on Argan nut shell and a polymer matrix: Effect of filler content and coupling agent.

This study aimed at developing a biocomposite using polypropylene (PP) as the matrix and Argan nut shell (ANS) as reinforcement. Also, styrene-(ethylene-butene)-styrene triblock copolymer grafted with maleic anhydride (SEBS-g-MA) was used as a coupling agent. The samples were prepared by using extrusion compounding followed by injection molding to determine the effect of filler and coupling agent content on the morphological, thermal, mechanical, and hygroscopic properties of the biocomposites.
