    ABSTRACT: The current study was aimed to evaluate the performance of direct 2,3,5-triphenyl tetrazolium chloride assay (direct TTC assay) and direct microscopic observation drug susceptibility assay (direct MODS assay) with indirect proportion method [(using Löwenstein-Jensen (LJ) media (Indirect LJ PM)] directly on Ziehl-Neelsen (ZN) smear positive sputum specimens. Direct AFB smear positive sputum specimens (n=264) were subjected to isoniazid (INH) and rifampicin (RIF) drug susceptibility testing by direct TTC assay, direct MODS assay and the performances were compared with indirect LJ PM. The direct TTC assay could demonstrate an overall sensitivity, specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) of 99.2%, 82.4%, 99.2% and 88.5%, respectively while the overall sensitivity, specificity, PPV and NPV of direct MODS assay was 98.8%, 82.4%, 99.2% and 78.2%, respectively for the detection of INH and RIF resistant MTB isolates when compared to indirect LJ PM method. The direct TTC assay was found to be an economical alternative method for the rapid and accurate detection of INH and RIF resistance from direct AFB smear positive sputum specimens.

    ABSTRACT: Disposal of Umbilical Cord Blood Units due to microbial contamination is a major problem in Cord Blood Banks worldwide as it reduces the number of units available for transplantation. Additionally, economic losses are generated as result of resources and infrastructure used to obtain such units. Umbilical Cord Blood Units that showed initial microbial contamination were subject to strains isolation, identification, and characterization by sequencing the 16S rRNA gene and Enterobacterial Repetitive Intergenic Consensus (ERIC-PCR). Moreover, tests of antimicrobial resistance/sensitivity and phenotypic activities that may play an important role in microbial infection were performed. Microbial contamination was detected in 120 Umbilical Cord Blood Units (2.31%) in the period from 2003 to 2013. The most frequently isolated strains were Enterococcus faecium, followed by Staphylococcus epidermidis, Escherichia coli, Enterococcus faecalis, Staphylococcus haemoliticus, Klebsiella pneumoniae, Enterococcus durans, Lactobacillus helveticus, Enterococcus hiriae and Roseomonas genomospecies 5. The ERIC-PCR assays revealed a wide genetic diversity in some strains although belonging to the same genus and specie, indicating different sources of contamination. Broad-spectrum penicillins, third generation cephalosporins, aminoglycosides, and fluoroquinolones showed lower inhibitory activity on the tested strains. All strains were proteolytic, 67.69% were amylase-positive, 27.6% hemolysis-positive, and 34.71% nuclease-positive. The most common sources of contamination were: vaginal flora, digestive tract, and skin flora, highlighting the need for staff training in good manufacturing practices in collection SCU since all contaminants identified are part of the microbial flora of the donors. Implications and consequences in the therapeutic use of Umbilical Cord Blood Units for transplantation contaminated by multiresistant bacteria in immunocompromised patients are discussed.

    ABSTRACT: Fungal arthritis is a rare complication of arthroscopic surgeries, but its possibility should always be considered due its deleterious effects on any joint. Infection caused by the fungus Histoplasma capsulatum is the most common cause of respiratory tract infections by fungi, meanwhile histoplasmosis arthritis is more rare than all other fungal infections. However, their atypical forms of arthritis and the importance of early diagnosis and treatment cannot be over-emphasized. Herein we report a case of knee monoarthritis in an immunocompetent patient with histoplasmosis arthritis following an arthroscopic meniscetomy, diagnosed by synovial biopsy and culture performed during a second arthroscopic procedure. The joint was debrided in this second intervention and the patient received itraconazole initially and fluconazole latter on. The arthritis subsided after 10 months of treatment.

    ABSTRACT: A delay in diagnosis of blood stream infection leads to improper treatment, yielding worse patient prognosis. However, not all clinical laboratories process blood culture examination during off-hours. For better management of patients, clinical laboratories should prepare their systems for blood culture examination even during off-hours. Copyright © 2015. Published by Elsevier Editora Ltda.

    ABSTRACT: Mycobacterium leprae infects skin and peripheral nerves causing deformities and disability. The M. leprae bacterium binds to ErbB2 on the Schwann cell surface causing demyelination and favoring spread of the bacilli and causing nerve injury. Polymorphisms at the ERBB2 gene were previously investigated as genetic risk factors for leprosy in two Brazilian populations but with inconsistent results. Herein we extend the analysis of ERBB2 variants to a third geographically distinct population in Brazil. Our results show that there is no association between the genotyped SNPs and the disease (p > 0.05) in this population. A gene set or pathway analysis under the genomic region of ERBB2 will be necessary to clarify its regulation under M. leprae stimulus.

    ABSTRACT: Background: Streptococcus pneumoniae, which cause noninvasive pneumococcal diseases, severely impair children's health. This study analyzed serotype distribution and antimicrobial resistance of S. pneumoniae from January 2012 to December 2012 in a Children's Hospital, Shanghai. Methods: A total of 328 pneumococcal isolates were serotyped by multiplex sequential PCR and/or capsule-quellung reaction. The minimum inhibitory concentrations for 11 antimicrobial agents were determined by broth microdilution method. Results: Among 328 strains, 19F (36.3%), 19A (13.4%), 6A (11.9%), 23F (11.0%), 14 (5.8%), 6B (5.2%), and 15B/C (4.3%) were the most common serotypes. The coverage rates of 7-, 10-, and 13-valent conjugate vaccines (PCV7, PCV10, and PCV13) were 58.2%, 58.2%, and 84.1%, respectively. Out of the isolates, 26 (7.9%) strains were penicillin resistant. Most of the strains displayed high resistance rate to macrolides (98.5% to erythromycin, 97.9% to azithromycin, and 97.0% to clindamycin). Conclusions: The potential coverage of PCV13 is higher than PCV7 and PCV10 because of the emergence of 19A and there should be long-term and systematic surveillance for non-vaccine serotypes.

    ABSTRACT: Objective: To describe the investigation of latent tuberculosis infection and indication for isoniazid preventive therapy in children and adolescents evaluated at the children's hospital. Methods: This retrospective study examines all latent tuberculosis infection subjects with indication for isoniazid preventive therapy attended during 2002-2009 at the pulmonology outpatient clinic from children's hospital in Rio de Janeiro, Brazil. The subjects were classified into three groups by origin: (G1) primary and secondary health units; (G2) children's hospital-pulmonology outpatient clinic; and (G3) children's hospital-specialty outpatient clinics. The association between the variables examined and G1 was analyzed using univariate analysis. Results: Of the 286 latent tuberculosis infection cases included 169 (59.1%) were from G1, 56 (19.6%) from G2, and 61 (21.3%) from G3. Latent tuberculosis infection diagnosis without isoniazid preventive therapy prescription was present in 142 (49.6%) cases before arrival at the pulmonology outpatient clinic: 135 (95.1%) from G1, three (2.1%) from G2, and four (2.8%) from G3. Variables associated with G1 were presence of isoniazid preventive therapy criteria before attending the pulmonology outpatient clinic (OR: 62.3; 26.6-146.2), negative HIV infection status (OR: 9.44; 1.16-76.3); contact with pulmonary tuberculosis (OR: 5.57; 1.99-15.5), and residing in Rio de Janeiro city (OR: 1.89; 1.04-3.44). Conclusion: Strategies that increase latent tuberculosis infection identification and isoniazid preventive therapy prescription in primary and secondary health units are urgently needed.
