| Background: Streptococcus bovis is a classical etiology of endocarditis and is associated with colonic lesions. No series of cases from Brazil has been described. Objectives: To describe aspects of S. bovis endocarditis. Methods: This is a case series of patients admitted to a cardiac surgery referral center, during the years 2005-2014. Clinical, laboratory, echochardiographic, colonoscopic, treatment, surgical and outcome variables were studied. Results: Nine patients with S. bovis endocarditis were included; all cases fulfilled the modified Duke criteria. Incidence was 8/220 (4%) in years 2006-2014. There were seven male and two female patients; mean age was 56.7 years, standard deviation 13.4. All patients had native aortic valve involvement.... |

| ABSTRACT Introduction Ventilator-associated pneumonia (VAP) is one of the most common healthcare-associated infections (HAI) in neonates admitted in neonatal intensive care units (NICUs). Methods We did a systematic review using PRISMA methodology to identify the main etiological agents in Brazilian NICUs. Eligible studies published without period restriction were identified in PUBMED, SCIELO, LILACS and DOAJ. Studies were included if they were conducted in neonates hospitalized at NICU. Studies done in outpatient care, neonates outside NICU, emergency department, primary care, long-term care facilities or a combination of these were excluded. Results We identified 6384 articles in the initial search and four papers met the inclusion criteria. In all... |

| ABSTRACT Since the beginning of the HIV burden, Visceral Leishmaniasis (VL)/HIV co-infection has been diagnosed not only in areas where VL is endemic (Latin America, India, Asia, Southern Europe), but also in North America, were it is considered an opportunistic disease. Clinical presentation, diagnostic tests sensitivity and treatment response in this population differs from VL alone. OBJECTIVES: To evaluate factors related to an unfavorable outcome in patients with VL/HIV diagnosis in a reference center in northeast Brazil. METHODS: Co-infected patients, diagnosed from 2010 to 2012, were included. Data from medical records were collected until one year after VL treatment completion. RESULTS: Forty-two HIV-infected patients were included in the... |

| ABSTRACT Objectives: To determine the factors associated with Mycobacterium tuberculosis complex-positive blood culture. Methods: Case-control study. Sociodemographic, clinical and laboratory data were collected from 2000 to 2015. Results: We reviewed medical records of 533 patients with culture-proven tuberculosis, of whom 27.2% (145/533) had blood culture available. Patients with mycobacteremia presented more frequently with abdominal tuberculosis, body mass index <18 kg/m2, and had lower hemoglobin and albumin levels. No differences were observed regarding HIV status. Conclusions: Few studies have reported on the characteristics associated with Mycobacterium tuberculosis complex bacteremia, especially among Human Immunodeficiency Virus-negative... |

| ABSTRACT Introduction Latent tuberculosis infection diagnosis based on the release of interferon-gamma in cultures of peripheral blood cells stimulated with Mycobacterium tuberculosis antigens has replaced the tuberculin skin test in many countries with low tuberculosis prevalence. The IFN-γ production can be influenced by genetic polymorphisms, of which the IFNG + 874 (rs62559044) locus is the most studied. We investigated the possible influence of the IFNG + 874 A/T polymorphism on interferon-gamma test performance. Methods Patients diagnosed with pulmonary tuberculosis (75), volunteers with positive tuberculin skin test (70) and healthy volunteers with negative tuberculin skin test and no history of contact with tuberculosis (57) were evaluated... |

| Enterotoxigenic Escherichia coli (ETEC) is recognized as the main cause of bacterial diarrhoea among children in Asia, Africa and Latin America but less investigated in Bolivia. OBJECTIVE: To determine the relation between enterotoxins, CFs and serotypes as well as the antimicrobial resistance patterns in a set of ETEC isolates collected from hospitalized children with acute diarrhea. In the present study we characterized 43 ETEC strains isolated from 2002 to 2006 from hospitalized children (0-5 years) with acute diarrhea in Bolivia. The strains were analyzed for heat-labile (LT) and heat-stable (ST) enterotoxins and colonization factor (CF) profiles, as well as for serogroups and antimicrobial resistance using phenotypic (ELISA, dot blot, slide... |

| Cryptococcus spp. are common causes of mycoses in immunocompromised patients. To determine the drug susceptibilities of clinical Cryptococcus spp. isolates, the characteristics of 61 clinical Cryptococcus spp. complex isolates and their antifungal susceptibilities were investigated, including 52 C. neoformans and 9 C. gattii isolates collected at Shanghai between 1993 and 2009. Antifungal susceptibility of clinical isolates to amphotericin B, fluconazole, itraconazole, and flucytosine were determined by the microdilution method M27-A2 and the ATB FUNGUS 3 kit. The 90% minimum inhibitory concentration (MIC90) and susceptibility ranges were as follows: 1 (0.0625-1) µg/mL for amphotericin B, 4 (0.125-16) µg/ mL for fluconazole, 0.25 (0.0313-4) µg/mL for... |

| We investigated the prevalence and the risk factors for infection with Helicobacter pylori in a randomly-selected population of adults from a low-income community in Northeastern Brazil. Helicobacter pylori infection was determined by ELISA. Risk factors were assessed using a structured interview. Two hundred and four individuals were included in the study, including 49 males and 155 females, ranging from 18 to 80 years old. Overall, 165 of 204 participants (80%) were H. pylori positive, without significant gender differences (p= 0.49). The infection rate was of 84.7% in subjects 18 to 30 years of age, increasing to 92% in subjects 46-60 years old. Above 60 years old, the prevalence decreased slightly. As a whole, the prevalence of infection did not... |

| We examined the clinical presentation and outcome of Brucellar infections of genitalia and the lower urinary tract through a review of the medical records of 10 cases of male patients with brucellar infections of the genitalia and lower urinary tract. The mean age of the patients with brucellosis was 49.2, (median 52, range 15-77 years). Eleven out of 17 patients were rural residents, 15 reported that they might have consumed unpasteurized dairy products) and four reported occupational exposure. Symptoms onset was acute in almost all cases. Scrotal pain, epidedimal swelling and fever were the most common symptoms. The Wright test was positive in 13 patients, while Brucella sp. was isolated from blood cultures in six cases. Only two patients were found with... |

| Leishmaniasis is a parasitic disease found in the continents of Europe, Asia, Africa and the Americas. In Brazil, the disease is an important public health problem, occurring in most states, but mainly in the Northeast region of the country, with the state of Alagoas having a significant number of confirmed cases. The present study establishes and discusses the epidemiological profile of cases of leishmaniases treated at the Reference Center of Alagoas, Hospital Escola Hélvio de Farias Auto, between January 2000 and October 2008. During thisperiod, records of 2,104 patients notified to the hospital Epidemiological Surveillance Center were reviewed. The epidemiology of leishmaniasis, both visceral and tegumentary, has shown a profile that has changed over... |

| Treatment of chronic hepatitis C is still unspecific. However, there is great expectancy concerning the new pegylated interferons. As there has been much controversy about the best parameters to determine whether treatment is effective, we analyzed several criteria currently used for evaluation, including serum alanine aminotransferase (ALT) normalization, viral load reduction and improvement of hepatic histology. |

| ABSTRACT A new point-of-care HIV viral load, mPIMA HIV-1/2 VL, Abbott, USA, has been recently developed. This point-of-care viral load requires no skilled person to run and uses a small plasma volume (50 µL). However, obtaining 50 µL of plasma can be a challenge in limited resource settings. We validated a simple and easy method to obtain enough amount of plasma to run a point-of-care viral load. The study utilized 149 specimens from patients failing antiretroviral therapy. At least 250 µL of whole blood was collected in a microtube/EDTA from fingerstick (fs-plasma) and immediately centrifuged. Parallel collection of venous blood to obtain plasma (vp-plasma) was used to compare performance in a point-of-care viral load assay and in methodology used in... |
