Chagas disease reactivation after autologous stem cell transplant. Case report and literature review.

Introduction: Chagas disease is an endemic parasitic infection in Latin America transmitted by triatomines. It is associated with risk factors such as poverty and rurality. After acute infection, a third of patients will present target organ involvement (heart, digestive tract, central nervous system).

Clinical and epidemiological characteristics and risk factors for mortality in patients with candidemia in hospitals from Bogotá, Colombia.

Background: Bloodstream infection by Candida species has a high mortality in Latin American countries. The aim of this study was to describe the characteristics of patients with documented bloodstream infections caused by Candida species in third level hospitals and determine the risk factors for in-hospital-mortality.

Methods: Patients from seven tertiary-care hospitals in Bogotá, Colombia, with isolation of a Candida species from a blood culture were followed prospectively from March 2008 to March 2009.

[The spread of KPC-3 Klebsiella pneumoniae in hospitals in Bogotá over a three-year period (2008-2010)].

Unlabelled: Introduction : One of the major worldwide public health problems today are the infections caused by carbapenem-resistant Enterobacteriaceae (CRE), among which carbapenem-resistant Klebsiella pneumoniae (CRKP), constitutes one of the most common pathogens causing nosocomial infection.

Objective: This study was aimed at describing the dissemination of KPC-3 enzyme-producing Klebsiella pneumoniae in clinical isolates from hospitals in Bogotá.

Materials And Methods: Eighty-two CRKP isolates collected from 10 hospitals in Bogotá from 2008-2010 were analysed; disk diffusion and microdilution were used for phenotypic detection of enzymes and PCR for genotyping.

[Behavior of carbapenemase-producing Klebsiella pneumoniae cases in cancer patients at a third level hospital in Bogotá, D.C].

Introduction: The presence of carbapenemase-producing Enterobacteriaceae in hospitals is increasingly common. Patients with advanced cancer who require invasive means for diagnosis, treatment or palliative care, and the use of broad-spectrum antimicrobials to treat secondary infections show increased susceptibility to infections caused by these bacteria.

Objective: To report the behavior of carbapenemase-producing Klebsiella pneumoniae (CPKP) isolates at the Instituto Nacional de Cancerología in Bogotá between January 2010 and December 2012.

[Tuberculosis of the breast].

We report a case of granulomatous mastitis caused by Mycobacterium tuberculosis in an immunocompetent woman with chronic inflammatory lesions of the breast. It was diagnosed by detection of mycobacteria DNA using polymerase chain reaction technique targeting IS6110 insertion element of M. tuberculosis complex in a paraffin-embedded histological specimen.

Risk factors for mortality caused by Staphylococcus aureus bacteremia in cancer patients.

Introduction: Staphylococcus aureus is the cause of 11-33% of nosocomial bloodstream infections and has a complication rate close to 50%. S. aureus accounts for 31% of isolates in the Instituto Nacional de Cancerología (INC), in Bogotá, Colombia, and is the main etiological agent of bacteremia.

Identifying and controlling a multiresistant Pseudomonas aeruginosa outbreak in a Latin-American cancer centre and its associated risk factors.

Pseudomonas aeruginosa is an important and frightening microorganism for patients suffering from cancer. Multiresistant P. aeruginosa (MRPA) may appear as a consequence of exposure to multiple antibiotics or from a breakdown in infection control practices.

[Community-acquired methicillin-resistant Staphylococcus aureus in Bogotá, Colombia: Public Health implications].

Objective: Determining the prevalence of methicillin-resistant Staphylococcus aureus (CA-MRSA) and susceptibility to erythromycin and clindamycin (resistance profile suggestive of being CA-MRSA) in community isolates from de GREBO's database from 2001-2005.

Materials And Methods: GREBO's database has been complied since 2001, using more than 22 hospitals in Bogota. S.

[Therapeutic approach to Staphylococcus aureus bacteremia].

Staphylococcus aureus is an important human pathogen, responsible for 11-33% of the bacteremias acquired in the hospital setting and nearly 50% of those acquired in the community at large. The epidemiology of S. aureus bacteremia is discussed, with an special emphasis on the situation in Colombia and the resistance mechanisms against the major drug groups used for the treatment.

[The 'bull's eye' pattern in hepatic tomography].

Invasive fungal infections are more commonly found in patients who develop neutropenia after chemotherapy. A 4-year-old girl with diagnosis of acute lymphoid leukemia developed febrile neutropenia after chemotherapy. Broad spectrum antibiotics and antimycotic therapy were initiated.
