Background: In Cameroon, the prevalence of HIV in pregnant women was 7.8% in 2012, and they were 8500 HIV positive newborns in 2013. Option B+ is the first highly active antiretroviral therapy (HAART) preventive protocol. The objective was to evaluate the rate of HIV transmission on children born from mothers who were on Option B+ during pregnancy, in three university teaching hospitals of the University of Yaoundé I. Methods: It was a retrospective, cross-sectional study over a period of four years (2013-2017). We included HIV positive mothers not on previous antiretroviral treatment and who received a single tablet daily of combined tenofovir (300 mg) + Lamivudine (300 mg) + Efavirenz (600 mg) started at any time during pregnancy. Newborn received nevirapine syrup according to WHO option B+ protocol. Results: 179 women were included. The average age was 33.5 ± 2.92 years, all ages were represented. Blood donation was the most frequent HIV positive screening opportunity, voluntary testing rate was 29% (29/179), and adherence rate was 98.9%. Few male partners were involved (58/179). Premature deliveries and low birth weight were rare (5/179;10/179)), the indication of mode of delivery was strictly obstetrical, newborn feeding choice didn’t affect the transmission outcome, and the mother to child transmission rate was 2.2% (4/179). Conclusion: Option B+ could achieve the lowest mother to child transmission ever in Cameroon and should be generalized in high endemicity low resources settings.

Journal of Minerals and Materials Characterization and Engineering 2013年第6期1卷 363-366页

作者： Salome Hephzibah Waziri Abdullahi Idris-nda.Irmiya Samson Amoka Yusuf Ishaq Department of Geology and Mining Ibrahim Badamasi University Lapai Nigeria Department of Geology Federal University of Technology Minna Nigeria

Geotechnical studies were carried out on soils from Shango-Chanchaga highway in Minna, in relation to the petrographic characteristics of the parent rock. Samples were obtained from 5 trial pits at 1 km interval for geotechnical analysis. The moisture content varies from 35.0% to 58.5%, liquid limit ranges from 29.0% to 43.0%, plastic limit ranges between 9.0% and 26.5%, while plasticity index ranges from 12.0 to 33.5. The optimum moisture content (OMC) ranges from 12.0 to 14.0, and California Bearing Ratio (CBR) ranges from 2 to 21. The diffractograms showed that the dominant minerals were clinochore (Mg,Fe)6(Si,Al)4O10(OH)8, quartz (SiO2), cordierite (Mg2Al4Si5O18Ar0.625), and albite (Na0.98Ca0.02Al1.02Si2.98O18). The results showed that there exists a relationship between the mineral composition, the texture of the rock, and the geotechnical characteristics of the soil types.

Open Journal of Modern Neurosurgery 2020年第2期10卷 260-266页

作者： Christine Milena Sayore nda.Bankole Loubna Rifi Nadia Cherradi Adyl Melhaoui Abdessamad Elouahabi Department of Neurosurgery Mohamed V University Rabat Morocco Department of Histopathology Mohamed V University Rabat Morocco

Langerhans cell histiocytosis (LCH) is a proliferation of Langerhans cells with inflammatory cells, characterized by the activation of histiocytic cells or their proliferation that affects structures of the human body, including the temporal bone which localization is rare in children. The objective of this study is to illustrate the clinical presentation, management and prognosis of this disease, and to compare our case with previously reported series. We report the case of a young 4-year-old patient with a history of otorrhea and recurrent otalgia, with left axillary non-blowing exophthalmia progressive since 5 months associated with indurated left temporal swelling and also an indurated swelling of posterior face of the left shoulder on pathological fracture. A cerebro-orbital MRI performed at home showed an extra-conical process with extension at the temporal fossa. The patient, then, underwent an open-air biopsy of the temporal mass and the pathological analysis returned to favor Langerhans cell histiocytosis. The diagnosis was made by immunohistochemical findings of the S-100 protein and/or the CD1 antigen. The child was treated by chemotherapy with a good outcome. Our results concord with literature. The prognosis is different and better in children with unifocal bone disease than those with a multifocal disease with a survival rate of 65% - 100%.

Microbial Ecology and Antibiotic Susceptibility Profile of Germs Isolated from Hospital Surfaces and Medical Devices in a Reference Hospital in Douala (Cameroon)

引用

Advances in Microbiology 2018年第2期8卷 125-137页

作者： Cécile Okalla Ebongue Chanceline Mayoudom Nguatcheussi Jean-Pierre nda.Mefo’o Joss Bollanga Dieudonné Adiogo Henry Namme Luma Laboratory of Clinical Biology General Hospital Douala Cameroon Department of Biological Sciences Faculty of Medicine and pharmaceutical Sciences University of Douala Douala Cameroon Committee for Hygiene and the Fight against Nosocomial Infections General Hospital Douala Cameroon

Background: The hospital environment is largely contaminated with pathogenic microorganisms. This colonization is a threat for hospitalized patients, especially in high-risk services. The purpose of this study was to identify the germs found on surfaces and medical devices in some departments of the General Hospital of Douala, and to establish their susceptibility profile to most commonly used antibiotics in this health facility. Results: We collected 114 surface and medical device samples, and seeded different culture media for Gram-positive and Gram-negative aerobic bacteria. Of the total samples, 108 were positive and 137 bacterial strains were isolated. The colony count revealed a high rate of contamination. Enterobacter cloacae was the most represented specie (53.3%), followed by Pseudomonas aeruginosa (22.6%) and Klebsiella pneumoniae (6.6%). Various coagulase-negative Staphylococci have been isolated in some departments, as well as Cryptococcus laurentii and molds. The isolated strains showed low susceptibility to the antibiotics tested. Enterobacter cloacae showed low susceptibility for all tested molecules, except for carbapenems with rates ranging from 82% to over 94% in Maternity, Intensive Care and Neonatology units. The strains coming from the Haematology Protected Ward were resistant to all antibiotics, except fluoroquinolones with a susceptibility rate of 50% for ofloxacin. Conclusion: The hospital surfaces and medical devices are highly contaminated by environmental bacteria, with low susceptibility rates to antibiotics. Microbiological controls of the environment should be regular in critical areas in order to reinforce measures to prevent diffusion of multi-resistant bacteria.

Detection of the Production of Klebsiella Pneumoniae Carbapenemase, New Delhi Metallo-Beta-Lactamase and Oxacillinase-48-Type Carbapenemases by Gram-Negative Bacilli in Resource-Limited Setting

引用

Advances in Microbiology 2021年第10期11卷 579-590页

作者： Cecile Okalla Ebongue Gabin Gaël Simo Jean Pierre nda.Mefo’o Grace Dalle Ngondi Emmanuel Roddy Mengue Guy Pascal Ngaba Dieudonne Adiogo Laboratory of Clinical Biology General Hospital Douala Cameroon Department of Biological Sciences Faculty of Medicine and Pharmaceutical Sciences Douala Cameroon Laboratory Unit Laquintinie Hospital Douala Cameroon Laboratory Unit Gyneco-Obstetric and Pediatric Hospital Douala Cameroon

Background: The increasing resistance of bacteria to various antibiotics is a worldwide public health issue. Carbapenems that have elicited great hope in treating infections caused by multidrug-resistant germs have seen their efficacy narrowed over time with the emergence of other novel resistance mechanisms, notably the production of Carbapenemases. Methods: A prospective cross-sectional study was conducted from May 2017 to May 2018 in Douala (Cameroon) to detect carbapenemase-producing Gram-negative bacilli. Isolated strains were identified using the Vitek2TM system. Antimicrobial susceptibility testing was performed using the Kirby-Bauer disk diffusion method on agar plates with 20 selected commercially available antibiotic discs. The bacterial strains were tested for the production of three Carbapenemases (OXA-48, NDM, KPC), using an immuno-chromatographic technique, with the “RESIST-3 O.K.N. K-SeT” rapid detection kit. Results: During the study period, 1687 strains of Gram-negative bacilli were isolated in selected laboratories with a total of 200 multi-resistant strains identified (11.9%). Among the multi-resistant strains, E. coli was the species most represented in Enterobacteriaceae (27.5%) followed by K. pneumoniae (15.5%) and the non-fermenting Gram-negative bacilli were predominantly P. aeruginosa (20.5%). These strains mainly came from urine and pus, i.e. 41% and 32% respectively. Thirty-two (16%) strains produced one of the Carbapenemases with a higher frequency at the General Hospital (84%). NDM-type carbapenemase was the most frequently identified (8.5%), OXA-48 type 7.5%, and no KPC production was observed. Among the Enterobacteriaceae 22.9% produced Carbapenemases and only 5.1% of the non-fermenting bacilli produced these enzymes. The isolates strains were completely resistant to all antibiotics except Amikacin and Fosfomycin. The strains producing the NDM-type carbapenemase
