Cryptococcal meningitidis is rare, occurring particularly in adults infected with the HIV virus. The authors report the cases of 2 immunocompetent girls who were 3 and 13. years old. The authors describe the risk factors, the clinical symptoms, and the biological characteristics of the cerebrospinal fluid. © 2010. Source

As part of the evaluation and the development of plant genetic resources of fodder and pastoral interest in Algeria, ten populations of sulla (Sulla coronaria (L.) Medik. Syn. Hedysarum coronarium L.) were subject to an assessment. The growth and the chemical composition of the populations were analyzed in this framework. The field trial is a randomized complete block design with four replications. Several parameters (seeds thousand weight, emergence of seedlings, number of plants per square meter, maximum height, maximum width, bloom, cutting date, green matter, dry matter, mineral matter, organic matter, crude fiber, fat, phosphorus, calcium, total nitrogen, Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF), lignin, hemicellulose) have been determined. Two ecological factors (altitude, rainfall) were also taken into account. The variance analysis indicated a significant variation between the populations regarding eight variables linked to the growth and the chemical composition of the plant. Many significant relationships were also highlighted. The results of the correlation matrix indicated also that the total nitrogen content is negatively correlated with the number of plants per square meter and the final height. Overall, the results of principal component analysis showed a good distribution of variables, particularly, the final width, the hemicellulose and the NDF. The descriptive analysis signalized also the part of the altitude and the rainfall characterizing the natural habitats of the populations. This study permitted a better understanding of the nature of variation established within this species. Sulla can play a significant role in the socio-economic and environmental development of rural communities. © 2014 Asian Network for Scientific Information. Source

Introduction: Pneumococcal infections are a major public health problem because of the virulence of this bacterium and its ability to develop resistance. Material and method: Two hundred and ninety-four strains of Streptococcus pneumoniae were isolated from sterile (56.8%) and non-sterile samples (43.2%), from January 2001 to July 2010. Results: The interpretation of antibiotic susceptibility testing, according to CLSI criteria (M100-S21 2011), yielded a 25.2% overall resistance to penicillin, with 23.5% of strains isolated from CSF (meningitis), and only 1.7% in other samples. Resistance to cefotaxime was 8.1% (including 4.4% at a high level). The most common serotypes were: 14 (19.5%), 23F (9.7%), 6B (9.3%), 19F (5.4%), and serotype 1 (5%). The percentage of these serotypes isolated from normally sterile sites in children under 5 years of age was 31.25% for 14, 10.4% for 23F, 8.3% for 19F, 6.25% for 6B, and 4.2% for serotype 1. The theoretical vaccinal coverage against invasive infections in children under 2 years of age was 61.5%, 69.2%, and 76.9% for the 7-valent, 10-valent, and 13-valent conjugate vaccines, respectively. Penicillin non-susceptible Streptococcus pneumoniae (PNSP) strains accounted for 67.1, 68.6, and 72.8% for each of these three vaccines. Conclusion: There was a variation of serotype rates compared to previous studies. The increase in pneumococcal antibiotic resistance is concerning, particularly for the treatment of pneumococcal infections in children and infants. Pneumococcal vaccination is not compulsory yet in Algeria. © 2011 Elsevier Ltd. Source

Recent classifications of non-Hodgkin's lymphomas based on combination of morphologic, immunophenotypic, and cytogenetic criteria have individualized mantle cell lymphoma (MCL). This clinico-biological entity which accounts for 3 to 10% of all non-Hodgkin's lymphomas, now appears to be a biological and therapeutic model for the understanding and treatment of hematologic malignancies. The present study consisting of two cases of MCL collated at laboratory of hematology of Rabat Ibn Sina hospital. The morphological appearance of MCL is characterized by diffuse or nodular lymph infiltration in the mantle zone, the osteo-medullary biopsy shows an interstitial infringement characterized by the presence of lymphocytes resembling centrocytes with cleaved and angular nuclei, dispersed chromatin, inconspicuous nucleoli and scanty cytoplasm. The flow cytometry showed immunophenotype positive for surface Ig, CD19, CD20, CD22, CD79b, CD5 and cyclin D1, and negative for CD10, CD23 and CD25. In conclusion, the methods of diagnosis and prognosis evaluation of mantle cell lymphoma are based on the nodular, medullary and blood morphology, the immunophenotypic, cytogenetic and molecular study of neoplastic cells.

Background and Objective: As part of the valorization of plant genetic resources of fodder and pastoral interest in Algeria, ten populations of subterraneun clover (Trifolium subterraneum L.) were subject to an evaluation. The objective of this study is the characterization of the Algerian populations of subterraneun clover on quantitative and qualitative level. This would permit to increase the number of fodder species used in the different areas of the country for developing the livestock. Materials and Methods: The field trial was a randomized complete block design with four replications. Then, the chemical composition of the populations was analysed at the laboratory. In this framework, several parameters were determined (Thousand seeds weight, seedlings, height, width, flowering, cutting date, green matter, mineral matter, organic matter, crude fiber, fat, phosphorus, calcium, total nitrogen, acid detergent fiber, neutral detergent fiber, lignin and hemicellulose). Two ecological factors (Altitude and rainfall) characterizing the natural habitat of the populations were considered. The data obtained have undergone statistical treatments (ANOVA/Tukey method). Then, the correlations and the principal component analysis were used for a better interpretation of the relations established between the different populations and the variables. Results: The variance analysis indicated that there is some variation in three variables linked to the cutting date, the thousand seed weight and the yield of green matter. It seems that there is no link between the variables and the ecological factors. The principal component analysis indicated that the calcium and the vegetative development in width are the variables, the best represented. Conclusion: Overall, the variables related to the chemical composition contribute more than those related to the vegetative development (number of variables), but the probabilities corresponding to the vegetative development are the most significant. This study would contribute to select the best populations of subterraneun clover in order to introduce them in the different agro-edapho-climatic areas, specially in the Mountains of the North East of Algeria, which is the most watered zone in the country. © 2016 R.
