“This study reports the antimicrobial resistance of Streptococcus pneumoniae, Haemophilus influenzae and Streptococcus pyogenes isolated from patients in Algeria, Morocco and Tunisia. 672 non-duplicate isolates were recovered from May 2006 to May 2007. The minimum inhibitory concentrations (MICs) were determined using the E-test and interpreted according learn more to EUCAST

guidelines. Among 236 S. pneumoniae, 47% were penicillin non-susceptible (PNSP) with 3% of strains being highly resistant; 20.4% and 17.4% had decreased susceptibility to amoxicillin and cefotaxime, respectively. Dual resistance to penicillin and erythromycin was observed in 30.1%. All isolates were susceptible to levofloxacin except one. Among 262 H. influenzae, 13.3% were amoxicillin-resistant and beta-lactamase producers.

Two isolates were beta-lactamase-positive and amoxicillin-clavulanate-resistant. All isolates were susceptible to cefixime, cefotaxime and levofloxacin. All S. pyogenes (17 4) were susceptible to beta-lactams with 5.7% LY2606368 price resistant to erythromycin. Five had decreased susceptibility to levofloxacin. These data on respiratory tract pathogens indicate the high prevalence of PNSP in North African countries.”
“Background : Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors in the gastrointestinal tract. Recently, many methods for the diagnosis of GIST have been developed including molecular diagnosis. Methods : We selected 90 cases of GIST that had presented at Kyungpook National University Hospital between 1998 and 2007. Tissue microarrays were made using core areas

of tumor tissues. Immunohistochemical staining for c-kit, protein kinase C-theta, and platelet-derived growth factor receptor alpha (PDGFRA) was done. Direct sequencing of hot spot exonal areas for c-kit and PDGFRA GSK2245840 were done using extracted DNAs of all 90 paraffin block tissues. Results : Among the 90 cases, 83.3% (75/90) were c-kit positive, 16.6% (15/90) were c-kit negative, 93.3% (84/90) were PDGFRA positive, and 6.6% (6/90) cases were PDGFRA negative. Fifteen cases of c-kit negative GIST included 1 case of PDGFRA negative and 5 cases of PDGFRA negative GIST were c-kit positive. The one case in which both c-kit and PDGFRA were negative, showed a c-kit mutation in exon 11. Conclusions : Combined immunohistochemical staining of c-kit, discovered on GIST 1 (DOG1) and PDGFRA is helpful for the diagnosis of GIST. When all staining tests are negative for immunoreactivity, c-kit mutation analysis for exon 11, 9 should be done. Genotyping of kit and PDGFRA do not need to be examined initially, if it is only for the diagnosis of GIST.”
