    ABSTRACT: The timing of most recurrences after neonatal urinary tract infection is during the first year of life, with peak incidence 2–6 months after the initial infection. Information on the microbiologic characteristics of recurrent urinary tract infection episodes in relation to the microbiology of the initial episodes is limited.

    ABSTRACT: In this study, 275 patients in use of tenofovir were retrospectively followed-up for three years to evaluate risk factors involved in impaired renal function. Analysis of variance (ANOVA) and Tukey's test were used to verify any differences in creatinine levels and estimated clearance (CKD-EPI equation) at 0, 6, 12, 24 and 36 months, adjusting for the co-variables sex, skin color, age >50 years, arterial hypertension, diabetes and the use of the ritonavir-boosted protease inhibitors (PI/r) lopinavir/r or atazanavir/r. The software package STATISTICA 10® was used for statistical analysis. The patients’ mean age was 43.2±10.7 years. Systemic arterial hypertension (SAH) and diabetes were found in 20.4% and 8.7% of the patients, respectively. Overall, 96.7% were on tenofovir associated with lamivudine (TDF+3TC), 39.3% on lopinavir/r, 29.8% on efavirenz, and 17.6% on atazanavir/r. At 24 months, there was a statistically significant difference in estimated creatinine clearance (CKD-EPI) when the co-variables male (F=3.95; p=0.048), SAH (F=6.964; p=0.009), and age over 50 years (F=45.81; p<0.001) were taken into consideration. Analysis of the co-variable use of atazanavir/r showed a tendency toward an increased risk over time (F=2.437; p=0.063); however, no significant time interaction was seen. At 36-month, a statistically significant difference was found for age over 50 years, (F=32.02; p<0.05) and there was a significant time-by-sex interaction (F=3.117; p=0.0149). TDF was discontinued in 12 patients, one because of a femoral neck fracture (0.7%) and 11 due to nephrotoxicity (4%). Of these latter cases, 9/11 patients were also using protease inhibitors. These data strongly alert that tenofovir use should be individualized with careful attention to renal function especially in male patients, over 50 years, with SAH, and probably those on ATV/r.

    ABSTRACT: Increased serum CA 19-9 levels in patients with nonmalignant diseases have been investigated in previous reports. This study evaluates the clinical significance of serum CA 19-9 elevation in pulmonary nontuberculous mycobacterial (PNTM) disease and pulmonary tuberculosis (TB). The median CA 19-9 level was higher in patients with PNTM disease than in patients with pulmonary TB (PNTM: 13.80, TB: 5.85, p<0.001). A multivariate logistic regression analysis performed in this study showed that Mycobacterium abscessus (OR 9.97, 95% CI: 1.58, 62.80; p=0.014) and active phase of PNTM disease (OR 12.18, 95% CI: 1.07, 138.36, p=0.044) were found to be risk factors for serum CA 19-9 elevation in PNTM disease. The serum CA 19-9 levels showed a tendency to decrease during successful treatment of PNTM disease but not in pulmonary TB. These findings suggest that CA 19-9 may be a useful marker for monitoring therapeutic responses in PNTM disease, although it is not PNTM disease-specific marker.

    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: 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.
