[Abdominal obstruction revealing colonic lymphoma: a case report].

Colonic lymphoma is a rare malignant gastrointestinal tumor that can be revealed by an exceptional and serious complication: intestinal obstruction. Treatment is based on surgery and chemotherapy. We here report a case of diffuse colonic large B-cell lymphoma revealed by occlusion and diagnosed based on the examination of surgical specimen in a 64-year-old man who was in complete remission after six courses of R-CHOP.

[Preventing relapse of acute leukemias and myelodysplastic syndromes in post-allograft transplantation: Prophylactic and preemptive strategies (SFGM-TC)].

Disease relapse remains the first cause of mortality of hematological malignancies after allogeneic hematopoietic stem cell transplantation (allo-HCT) for acute myeloid and lymphoid leukemia (AML and ALL) and for myelodysplastic syndroms (MDS). More and more patients are eligible for allo-HCT over the years and for many of them, only reduced intensity conditioning is possible, which is associated with a higher risk of relapse. Knowledge and biotechnology allow us to better identify diseases at very high risk of relapse and to measure residual disease before allo-HCT.

[Acquired bone marrow aplasia in children and young adults under the age of 30: Experience of the Pediatric Hematology and Oncology Department of the 20 August Hospital, Casablanca].

Bone marrow aplasia is a rare and serious hematologic disorder. Although benign, it is a hematologic disorder whose prognosis can be poor and whose spontaneous development can be fatal. Treatment is long, difficult and costly.

[Acquired severe aplastic anemia in emerging countries: Management from allogeneic hematopoietic cell transplantation indication until post-transplant follow-up SFGM-TC].

Management of acquired aplastic anemia (AA) in emerging countries depends on the means of prognostic stratification, treatment and logistics available. During the 13th annual harmonization workshop of the francophone Society of bone marrow transplantation and cellular therapy (SFGM-TC), a designated working group reviewed the literature in order to elaborate unified guidelines for allogeneic hematopoietic cell transplantation (Allo-HCT) in this disease. In terms of practice, the conclusions are as follows; The use of anti-tymocyte globuline (ATG) is mainly from rabbit and very little from horse.

Radiology of malignant degeneration of pilonidal sinus: Report of a case and review of the literature.

Pilonidal sinus disease is a frequent and recurrent pathology in young adults, with a male predominance, while malignant transformation of the pilonidal sinus is a rare complication, it occurs in 0.1% of patients, with a poor prognosis. Early surgical removal of the primary lesion remains the best treatment.

[Addiction to psychoactive substances among resident physicians in Morocco: A multicenter cross-sectional study].

Introduction Substance use among resident physicians is an underestimated, poorly understood, and serious problem because of its negative consequences for the health of physicians and also for the health and safety of the patients in their care. Objective To estimate the prevalence and identify factors associated with addictive behaviors among resident physicians at different university hospitals in Morocco. Method We conducted a multicenter cross-sectional descriptive and analytical study involving resident doctors from the 7 university hospital centers in Morocco.

Virological characterization of Hepatitis B virus infection in Morocco: A ten-years study (2014 - 2023).

In alignment with Morocco's national strategy for eliminating viral hepatitis, we aimed to characterize and update the virological profile of chronic hepatitis B patients. Demographic, serological and molecular parameters of 804 HBsAg-positive patients were retrospectively analyzed. Overall, 58.

NOD1 and NOD2 genetic variants: Impact on hepatocellular carcinoma susceptibility and progression in Moroccan population.

Background: Nucleotide-binding oligomerization domain 1 (NOD1) and NOD2 are involved in carcinogenic processes by recognizing bacterial cell wall components and triggering inflammation. This study explored the association between genetic variations in NOD1 and NOD2 and susceptibility to hepatocellular carcinoma (HCC) and its progression in a Moroccan population.

Methods: Genotyping of NOD1 rs2075820 (C>T) and NOD2 rs718226 (A>G) was performed using the TaqMan allelic discrimination assay in 467 Moroccan individuals.

[Fatal outcome of complete resection of undifferentiated pleomorphic cardiac sarcoma : About a case].

Introduction: Undifferentiated pleomorphic sarcoma (UPS) is a very rare malignant primary cardiac tumor with a poor prognosis.

Observation: A 34-year-old woman complained of dyspnea evolving in a febrile context with altered general condition: Transthoracic echocardiography (TTE) revealed a left intra-atrial mass measuring 51/26 mm in diameter. A thoracic computed tomography (CT) revealed a mass occupying the left atrium measuring 42/28/34 mm, associated with two pulmonary metastases.

Tenebrio Molitor breeding rejects as a high source of pure chitin and chitosan: Role of the processes, influence of the life cycle stages and comparison with Hermetia illucens.

This work valorizes rejects from Tenebrio Molitor TM breeding through the production of chitin and chitosan. Two processes are proposed for extracting chitin from larval exuviae and adult. The first process P1 provides chitin with high contents compared to literature data but the characterization shows the presence of impurities in the exuviae chitin responsible for the shifts in the values of the physicochemical characteristics towards those presented by γ chitin.

The rise and future of CRISPR-based approaches for high-throughput genomics.

Clustered regularly interspaced short palindromic repeats (CRISPR) has revolutionized the field of genome editing. To circumvent the permanent modifications made by traditional CRISPR techniques and facilitate the study of both essential and nonessential genes, CRISPR interference (CRISPRi) was developed. This gene-silencing technique employs a deactivated Cas effector protein and a guide RNA to block transcription initiation or elongation.

[Thrombolysis alert in ischemic stroke: experience of the international private clinic Al Badie in Fez (cross-sectional study of 60 cases)].

Intravenous thrombolysis is the standard treatment for acute ischemic stroke. We here report the cases of thrombolysis alert in the private sector in Morocco We conducted a prospective study of all patients with neurological deficit of sudden onset occurred within the first 12 hours admitted to the Emergency Department of the Al Badie international private clinic from January 2022 to September 2023. Epidemiological, clinical and etiological characteristics as well as data on outpatient and inpatient delays were collected.

[Characteristics and needs of patients requiring nephrology care: A review of the literature].

Chronic kidney disease (CKD) is a public health problem. However, the management of patients with CKD is confined to the diagnosis of the disease and its conventional treatment by dialysis or renal transplantation. The aim of this article is to describe the specific characteristics of patients suffering from kidney disease and to determine their needs according to the stage of their renal disease.

[Phytoplankton population dynamics along the Casablanca - El Jadida Atlantic coast].

Our taxonomic study from March 2014 to November 2015 along the atlantic coast between Casablanca and El Jadida revealed that phytoplanktonic structure is mainly represented by Diatoms (Bacillariophyceae), Dinoflagellates (Dinophyceae), Silicoflagellates (Dictyophyceae) and Euglenophyceae with a clear dominance of Diatoms and Dinoflagellates. A total of 101 taxa of planktonic algae have been identified revealing a relatively diversified taxocenosis. In terms of respective diversity, the Diatoms are represented by 62 taxa (61.
