Nontraumatic popliteal pseudoaneurysm: A rare entity with different etiologies.

Pseudoaneurysms of the popliteal artery represent a rare vascular pathology. Leaving aside traumatic antecedents, in the presence of sudden swelling of the popliteal region, it is useful to suspect this entity, especially in the presence of infectious processes or connective tissue disorders. We present two cases from our institution where management included surgical intervention and control of the underlying diseases.

Retrospective Study of T Cell Leukaemia (Large Granular Lymphocyte Variant) in Dogs Associated with Suspected Immune-Mediated Cytopaenia(s) in the Absence of Peripheral Lymphocytosis.

Canine chronic large granular lymphocyte (LGL) leukaemia is commonly characterised by moderate to marked lymphocytosis but not neutropaenia. In humans, LGL leukaemia is often associated with autoimmune disorders, including immune-mediated cytopaenias (mainly neutropaenia). This presentation is rare in dogs.

[Group B streptococcal early-onset neonatal sepsis in the area of Barcelona (2004-2010). Analysis of missed opportunities for prevention].

Objectives: To study the evolution of the incidence of early-onset neonatal sepsis (EOS) by Streptococcus agalactiae in the area of Barcelona and to analyze failure of compliance with the prevention protocol.

Methods: A retrospective review was carried out on EOS cases in 8 Health-Care Centers in the Barcelona area between 2004 and 2010.

Results: Forty-nine newborns from 48 mothers were diagnosed with EOS.

Predicting survival in adults with invasive aspergillosis during therapy for hematological malignancies or after hematopoietic stem cell transplantation: Single-center analysis and validation of the Seattle, French, and Strasbourg prognostic indexes.

In this retrospective monocenter study, we analyzed the outcomes of 130 adult hematological patients who developed a proven (n = 23), probable (n = 71), and possible (n = 36) invasive aspergillosis (IA) in a 13-year period. Forty-nine patients (38%) were recipients of an allogeneic hematopoietic stem cell transplantation (AlloHSCT). The main goal of the study was the identification of prognostic factors for 4-month aspergillosis free survival (AFS) and overall survival (OS).

Epidemiology, risk factors, and prognosis of Candida parapsilosis bloodstream infections: case-control population-based surveillance study of patients in Barcelona, Spain, from 2002 to 2003.

Candida parapsilosis has emerged as an important yeast species causing fungemia. We describe the incidence and epidemiology of C. parapsilosis fungemia.

Candidemia in neonatal intensive care units: Barcelona, Spain.

Background: Candida spp. are increasingly important hospital-acquired pathogens in neonatal intensive care units (NICU) and cause considerable mortality in preterm infants. Most studies have been limited to a single institution.

Epidemiology and predictors of mortality in cases of Candida bloodstream infection: results from population-based surveillance, barcelona, Spain, from 2002 to 2003.

We conducted population-based surveillance for Candida bloodstream infections in Spain to determine its incidence, the extent of antifungal resistance, and risk factors for mortality. A case was defined as the first positive blood culture for any Candida spp. in a resident of Barcelona, from 1 January 2002 to 31 December 2003.

In vitro susceptibilities of bloodstream isolates of Candida species to six antifungal agents: results from a population-based active surveillance programme, Barcelona, Spain, 2002-2003.

Objectives: The antifungal drug susceptibilities of 351 isolates of Candida species, obtained through active laboratory-based surveillance in the period January 2002-December 2003, were determined (Candida albicans 51%, Candida parapsilosis 23%, Candida tropicalis 10%, Candida glabrata 9%, Candida krusei 4%).

Methods: The MICs of amphotericin B, flucytosine, fluconazole, itraconazole, voriconazole and caspofungin were established by means of the broth microdilution reference procedure of the European Committee on Antibiotic Susceptibility Testing.

Results And Conclusions: Amphotericin B and flucytosine were active in vitro against all strains.

Invasive disease caused by Haemophilus influenzae: the sensitivity of statutory reporting.

Purpose: The objective of the study was to investigate the sensitivity of the statutory reporting of Haemophilus influenzae invasive disease (HIID) during the period between 1996 and 1997 in Catalonia, Spain.

Methods: The incidence of HIID reported passively by clinicians was compared with the cases detected by a system of microbiological surveillance. In all cases isolated, the age of the patient, the clinical form and the serotype were investigated.

[Decreasing incidence of perinatal group B streptococcal disease (Barcelona 1994-2002). Relation with hospital prevention policies].

Introduction: To analyze the incidence of perinatal sepsis due to group B streptococcus (GBS) as related to compliance with recommendations for its prevention issued by the Catalan Societies for Obstetrics, for Pediatrics, and for Infectious Diseases and Clinical Microbiology in 1997.

Methods: The study was conducted from 1994 to 2001 in 10 Barcelona-area hospitals, where 157,848 live infants were born.

Results: GBS disease was diagnosed in 129 neonates.
