Gastrointestinal lymphoma in Western Algeria: pattern of distribution and histological subtypes (retrospective study).

Background: Primary gastrointestinal (GI) lymphomas (GIL) are uncommon diseases that can involve the whole GI tract. Considerable variation exists in the literature with respect to incidence of the various histological subtypes and sites of involvement. This study was undertaken to establish the anatomic distribution, histological subtypes and sites of GI lymphomas of patients from Western Algeria.

Immunohistochemistry and scoring of Ki-67 proliferative index and p53 expression in gastric B cell lymphoma from Northern African population: a pilot study.

Background: This study aimed to clarify the Ki-67 distribution, p53 expression and their relationship with clinico-pathologic features of gastric B cell lymphoma from Northern African population.

Methods: Twenty paraffin blocks of gastric lymphoma were retrieved from the archival materials of Department of Pathology, Central University Hospital of Sidi Bel Abbes (Western Algeria) from 2007 to 2013. Four µm section specimens were stained by immunohistochemical (IHC) technique with Ki-67 and p53 tumor markers.

Use of GeneXpert Mycobacterium tuberculosis/rifampicin for rapid detection of rifampicin resistant Mycobacterium tuberculosis strains of clinically suspected multi-drug resistance tuberculosis cases.

Background: Multi-drug resistance (MDR) TB is defined as tuberculosis (TB) disease caused by a strain of Mycobacterium tuberculosis (MTB) that was resistant to at least isoniazid and rifampicin (RIF). Emerging Multidrug-Resistant TB is one of the major concerns of health policy and rapid detection of M. tuberculosis and detection of RIF resistance in infected patients are essential for disease management.
