Colorectal cancer in a region of western of Algeria: results of 581 cases in 5 years.

Aims: The objective of this work is to evaluate the epidemiological profile of colorectal cancers, histologically proven over a 5-year period (2012-2016) in the Tlemcen region.

Methods: A retrospective study of 581 cases of colorectal cancer collected at the epidemiology department of the University Hospital Center (UHC) of Tlemcen between January 2012 and December 2016 was performed. Epidemiological data were processed using SPSS version 25 and Microsoft Excel 2010.

Retrospective epidemiological study on stomach cancer in a region of western Algeria: about 394 cases between 2011 and 2015.

Purpose: Stomach cancer is a major global health problem; it is one of the ten most common cancers with poor survival, and its incidence is characterized by wide variation. The aim of this work is to carry out a retrospective epidemiological study on gastric cancer in the wilaya of Tlemcen (West Algeria) over a period of 5 years (2011-2015).

Methods: The data set was provided by the cancer registry of the Tlemcen wilaya.

Bacteriological water quality and biofilm formation in the treatment system of the hemodialysis unit in Tlemcen, Algeria.

Objective: To evaluate and compare the microbiological quality of osmosis water at the distribution loop, at the dialysis generator inlet and to study the prevalence of biofilm in the tubing.

Methods: Microbiological analysis of 20 water loop samples, 10 water samples were taken at the machine entry and 10 pipe segments from tubing connecting the machines to the loop was done.

Results: The bacterial enumeration results of the loop water vary from 90 to 150 CFU/mL, while the average number of bacteria at the entry of the machines was 182 CFU/mL.

Characterization of uropathogenic ESBL-producing Escherichia coli isolated from hospitalized patients in western Algeria.

Introduction: The aim of this study is to assess the prevalence and molecular characterization of uropathogenic Extended spectrum β-lactamases (ESBLs) producing Escherichia coli.

Methodology: During 3 years, all hospitalized patients at the University-affiliated hospital of Tlemcen and presenting urinary tract infections caused by E. coli were considered as potential study participants.

[HPV DNA genotyping: A study of anogenital, head and neck and skin cancers in a population from west Algerian. HPV detection in different cancers from an Algerian population].

Objectives: To investigate the prevalence of human papillomaviruses (HPV) in cancers located at different sites in patients from west Algerian and collected between 2010 and 2014.

Material And Methods: Extracted DNA from archival formaldehyde-fixed and paraffin-embedded tissues was provided from 39 anogenital cancers, 10 head and neck cancers and 36 skin cancers. The viral DNA was detected using the INNO-LiPA HPV Genotyping Extra(®) kit.

Comparisons between geographically diverse samples of carried Staphylococcus aureus.

Approximately one-third of the human population is asymptomatically colonized by Staphylococcus aureus. However, much of the global diversity within the carriage populations remains uncharacterized, and it is unclear to what degree the variation is geographically partitioned. We isolated 300 carriage isolates from 1,531 adults contemporaneously in four countries: France, Algeria, Moldova, and Cambodia.

Diversity of staphylococcal cassette chromosome mec structures in methicillin-resistant Staphylococcus epidermidis and Staphylococcus haemolyticus strains among outpatients from four countries.

In staphylococci, methicillin (meticillin) resistance (MR) is mediated by the acquisition of the mecA gene, which is carried on the size and composition variable staphylococcal cassette chromosome mec (SCCmec). MR has been extensively studied in Staphylococcus aureus, but little is known about MR coagulase-negative staphylococci (MR-CoNS). Here, we describe the diversity of SCCmec structures in MR-CoNS from outpatients living in countries with contrasting environments: Algeria, Mali, Moldova, and Cambodia.
