Factor V Leiden G1691A (FVL) and Factor II prothrombin G20210A (PGM) mutations are the leading causes of thrombophilia. In this study, we have investigated the prevalence of the FVL G1691A and PGM G20210A single nucleotide polymorphisms (SNPs) among Libyan deep vein thrombosis (DVT) and myocardial infarction (MI) patients. SNP genotyping was performed using high-resolution melt analysis (HRM) and DNA sequencing. Biochemical parameters conducted on 112 males and 93 females showed no significant difference in means between the control group and the deep vein thrombosis and myocardial infarction groups. For Factor V Leiden, 40 samples were genotyped. Of the 40 samples, 6 (15.0%) of them were heterozygous and no one was homozygous. As for Factor II SNP, 59 samples were genotyped and only 2 (3.3%) were heterozygous. All the heterozygous samples showed 100% concordance between the HRM-PCR and DNA sequence analysis. Our study showed, for the first time, that both the FVL and PGM mutations are present among Libyan DVT and MI patients and that the FVL mutation is significantly associated with DVT but not with MI. However, our results do not support the association of PGM G20210A mutation with DVT or MI. arabic 18 English 117

Abstract The incidence of spinal cord injuries is the lowest of all major trauma, with devastating impact on the individual affected. The immediate treatment, though it remains mainly supportive, in many situations will determine the outcome and the cost of health care. Standards of care are unfortunately still lacking, this is mainly due to the existing controversies and lack of effective treatment of the injured cord. The author discusses here some of the controversial points based on literature review and personal observation. arabic 14 English 75

Abstract Introduction: Extended-spectrum β-lactamases (ESBLs), AmpC type, carbapenem resistant Enterobacteriaceae (CRE), are important mechanisms of resistance among Enterobacteriaceae. The aim of this study was to investigate the prevalence of ESBL, AmpC and CRE among Enterobacteriaceae isolates recovered from pediatric patients in Tripoli, Libya. Methods: This cross-sectional study was carried out in Tripoli Children Hospital (TCH), a total of 915 Gram negative bacteria isolates were evaluated for susceptibility to a panel of antimicrobials and were analyzed phenotypically for the ESBL, AmpC type and CRE using chromagen media, E-test and combination disc test. Results: The predominant organisms were Escherichia coli (56.8%) and Klebsiella spp. (21.4%). The overall prevalence of ESBL producing Enterobacteriaceae was 24.5% (224/915). Out of 224, Enterobacteriaceae proved ESBL producer, Klebsiella spp. (54%) and E. coli (34.4%) were the leading ESBL producers. ESBL-producers were more often resistant to major classes of antibiotics compared with non-ESBL producers, significantly high resistance rates (P < 0.001) were observed for ceftriaxone, cefepime, and ceftazidime (87.5 - 95.9%) among ESBL producers compared to non-ESBL producers (7.2 - 13.5%). MDR was documented for 50/224 (22.3%) of ESBL producers and was significantly higher (P < 0.0001) among ESBLs compared with non-ESBL producer isolates. Phenotypic detection of AmpC revealed 60/915 (6.6%) isolates as potential AmpC β-lactamase producers, E. coli exhibited a lower level of AmpC (8.3%) compared with Klebsiella spp. (56.6%). The overall prevalence of CRE was 9% (83/915). Carbapenemase-producing organisms in this study were as follows: Klebsiella spp. (44.6%); Acinetobacter spp. (24%); Pseudomonas spp. (9.6%). Conclusion: This study revealed that the prevalence of ESBL, AmpC, CRE and MDR Enterobacteriaceae isolates in Children hospital was within acceptable frequency. arabic 11 English 91
