Abstract
BACKGROUND There is an urgent need for alternative rescue therapies in invasive infections caused by methicillin-resistant Staphylococcus aureus (MRSA). We assessed the clinical efficacy and safety of the combination of fosfomycin and imipenem as rescue therapy for MRSA infective endocarditis and complicated bacteremia. METHODS The trial was conducted between 2001 and 2010 in 3 Spanish hospitals. Adult patients with complicated MRSA bacteremia or endocarditis requiring rescue therapy were eligible for the study. Treatment with fosfomycin (2 g/6 hours IV) plus imipenem (1 g/6 hours IV) was started and monitored. The primary efficacy endpoints were percentage of sterile blood cultures at 72 hours and clinical success rate assessed at the test-of-cure visit (45 days after the end of therapy). RESULTS The combination was administered in 12 patients with endocarditis, 2 with vascular graft infection, and 2 with complicated bacteremia. Therapy had previously failed with vancomycin in 9 patients, daptomycin in 2, and sequential antibiotics in 5. Blood cultures were negative 72 hours after the first dose of the combination in all cases. The success rate was 69%, and only 1 of 5 deaths was related to the MRSA infection. Although the combination was safe in most patients (94%), a patient with liver cirrhosis died of multiorgan failure secondary to sodium overload. There were no episodes of breakthrough bacteremia or relapse. CONCLUSIONS Fosfomycin plus imipenem was an effective and safe combination when used as rescue therapy for complicated MRSA bloodstream infections and deserves further clinical evaluation as initial therapy in these infections.

Abstract
Scapular spine stress fractures have been scarcely reported in the literature. Their pathomechanics, clinical course and treatment are not well established. We review 3 cases in 2 patients that were associated with cuff dysfunction. On follow-up, none of these fractures progressed to healing. Two of them needed osteosynthesis and bone grafting, and the third one became a painless non-union. The authors propose the combination of 3 factors as a reason for this lesion: a functionally impaired cuff, a greater activation of the muscles with origin and insertion in the spine-acromion and a fragile bone. As we believe that these fractures are unstable, and non-union would be expected, their surgical management is recommended.

Abstract
INTRODUCTION AND OBJECTIVE Distal humerus fractures in the elderly frequently associated with poor bone quality and comminution, making it harder to achieve proper osteosynthesis. Our aim is to evaluate the radiological and functional results of open reduction and internal fixation of these fractures. MATERIAL AND METHODS Retrospective study of 26 patients treated by open reduction and internal fixation between the years 2005-2010. Mean follow-up was 42 months. At final follow-up, a radiography evaluation (Knirk and Jupiter score) and clinical examination using Mayo Elbow Performance Score and Quick-Disabilities of the Arm, Shoulder and Hand Score was performed. Mean age of the group was 76.8 years (65-89), with 83% of the patients being female. Sixteen patients suffered type C fractures and 8 type A by AO classification. All underwent posterior surgical approach. RESULTS Mean elbow flexion reached 118.86°, with a mean extension deficit of 25°. More than 3-quarters (79.1%) of the patients showed 0-1 grade degenerative changes on the X-ray films at final follow-up. Functional results reached an average 19.87 points on Quick-Disabilities of the Arm, Shoulder and Hand Score, and 85 points on Mayo Elbow Performance Score scores. Non-union occurred in 2 cases: distal humerus in one patient and olecranon osteotomy in another. Ulnar nerve neuropraxia was recorded in 2 cases, and radial nerve in one. All 3 recovered uneventfully. Revision surgery was required, with 2 patients needing hardware removal and one a new fixation. DISCUSSION Treatment by open reduction and internal fixation with plating in elderly people for type A and C distal humerus fractures gives good functional results regarding this population, and thus scarcely disturbs their quality of life.

Abstract
Gastric plication is an emerging bariatric procedure with the potential for providing safe and significant weight loss and improvement of metabolic parameters without resection, bypass, or implantable device. Laparoscopic plication consists of infolding the greater gastric curvature to reduce stomach volume using running sutures. As a new procedure in bariatric/metabolic surgery very few clinical studies are available. Herein we present technical notes about and evidence from literature.

Abstract
OBJECTIVES To determine the epidemiology of bacteraemic Catheter-Acquired Urinary Tract Infection (CA-UTI) and to identify independent predictors of mortality. METHODS This study was part of a bloodstream infection surveillance study that prospectively collected data on consecutive patients with bacteraemia in our institution from 1991 to 2010. Factors associated with 30-day mortality were determined. RESULTS CA-UTI was the confirmed source of 1007 bacteraemias. The most common microorganisms isolated were Escherichiacoli (42%), Klebsiella spp (15%), Enterococcus faecalis (12%) and Pseudomonas aeruginosa (12%). Along the 2006-2010 periods, antibiotic-resistant E. coli and Klebsiella spp isolates accounted for 49% of the bacteraemia due to CA-UTI. Shock and mortality accounted for 125 and 92 cases, respectively (12% and 9%). Factors associated with mortality were: inappropriate empirical treatment (OR: 1.86, 95% CI: 1.48-2.44), ultimately or rapidly fatal prognosis of underlying disease (OR: 2.56, 95% CI: 1.48-4.44) and shock on presentation (OR: 12.62, 95% CI: 7.61-20.95). Inappropriate empirical treatment was most frequent in cases of bacteraemia produced by antibiotic-resistant E. coli or Klebsiella spp, Enterococcus spp. and P. aeruginosa. Factors associated with the isolation of a microorganism of this type were previous antibiotic therapy and healthcare-associated bacteraemia (OR: 1.50, 95% CI: 1.16-2.14 and OR: 3.03, 95% CI: 2.22-4.01, respectively). CONCLUSIONS In cases of previous antibiotic therapy or healthcare-associated bacteraemic CA-UTI may indicate the need to initiate empirical therapy activity against antibiotic-resistant Enterobacteriaceae, E. faecalis and P. aeruginosa.

Abstract
INTRODUCTION The idea of establishing an examination that accredits the training of the specialists in orthopaedic surgery at the end of their educational period as residents is subject to controversy. With the aim of encouraging the development of this examination, the present members of the National Commission of the Specialty of Orthopaedics (CNE) have reviewed the results obtained in previous examination. MATERIALS AND METHODS The results of the voluntary final exam for Orthopaedics residents, and of the surveys of participant opinions for the years 2006 to 2011 are presented. RESULTS The total number of participants was 231, growing from 19 in 2005, to 71 in 2011. The overall mean score in the period reviewed (2006-2011) was 6.72 out of 10 points. In these 6 years, 9 participants failed (4.25%). The mean score for the test was 7.57. The overall mean score of the oral exam was 6.57. The worst results were obtained in the general knowledge section of the oral examination. Nobody has ever failed the section on reconstruction of the lower extremity. The upper extremity section in the oral examination achieves the best average results. DISCUSSION The examination has established its place in the structure of orthopaedic resident training in our country, even without making it official by the Administration. We must positively acknowledge those candidates who chose to take the examination and be evaluated by their peers in order to prove their qualification and distinction. This recognition will be the best encouragement for future generations.

Abstract
OBJECTIVES To determine the epidemiology of bacteraemia due to biliary tract infection (BTI) and to identify independent predictors of mortality. METHODS This study was part of a bloodstream infection surveillance study that prospectively collected data on consecutive patients with bacteraemia in our institution from 1991 to 2010. BTI was the confirmed source of 1373 patients with bacteraemia, and the independent prognostic factors of 30 day mortality were determined. RESULTS The mean age of patients with biliary sepsis was 71 years (± 14 years). The most frequent comorbidities were biliary lithiasis and solid-organ cancer [484 cases (35%) and 362 cases (26%), respectively]. The BTI was healthcare-associated in 33% of patients. Shock and mortality accounted for 209 and 126 cases, respectively (15% and 9%). The most frequent microorganisms isolated were Escherichia coli (749, 55%), Klebsiella spp. (240, 17%), Enterococcus spp. (171, 12%), Pseudomonas aeruginosa (86, 6%) and Enterobacter spp. (63, 5%). There were 47 (3%) cefotaxime-resistant (CTX-R) E. coli or Klebsiella spp. Inappropriate empirical antibiotic treatment was an independent factor associated with mortality (OR 1.4, 95% CI 1.1-1.7). Inappropriate empirical treatment was more frequent in P. aeruginosa and CTX-R Enterobacteriaceae bacteraemia. These microorganisms were significantly more common in patients with previous antibiotic therapy, solid-organ cancer or transplantation and in healthcare-associated bacteraemia. CONCLUSIONS In patients with bacteraemic BTI, inappropriate empirical therapy was more frequent in P. aeruginosa and CTX-R Enterobacteriaceae infection and was associated with a higher mortality rate. In patients with bacteraemia due to BTI and solid-organ cancer or transplantation, healthcare-associated infection or previous antibiotic treatment, initial therapy with piperacillin/tazobactam or a carbapenem would be advisable.

Abstract
The aim of this study was to evaluate the clinical characteristics, predictors and outcomes of pneumococcal pneumonia developing pulmonary complications and the distribution of pneumococcal serotypes. It was a prospective study including all adult patients admitted to the Hospital Clinic of Barcelona, Spain (2001-2009) with the diagnosis of pneumococcal pneumonia. Microbiological investigation was systematically performed, including antimicrobial susceptibility and serotype distribution (only invasive strains isolated during 2006-2009). Complicated pneumonia was defined as the presence of one or more pulmonary complications: pleural effusion, empyema, or multilobar infiltrates. We included 626 patients, and 235 (38%) had the following pulmonary complications: pleural effusion, 122 (52%); empyema, 18 (8%); and multilobar infiltration, 151 (64%). Forty-six (20%) patients had more than one complication. Patients with pulmonary complications showed a higher rate of intensive-care unit admission (34% vs. 13%, p <0.001), a higher rate of shock (16% vs. 7%, p <0.001), a longer length of stay (9 days vs. 6 days, p <0.001), and a lower rate of penicillin resistance (14% vs. 25%, p 0.013), but similar mortality (9% vs. 8%). No significant differences were observed in the serotype distribution between complicated and uncomplicated pneumonia. Chronic obstructive pulmonary disease (COPD) (OR 0.38, 95% CI 0.23-0.63; p <0.001) was a protective factor against pulmonary complications, whereas chronic liver disease (OR 3.60, 95% CI 1.71-7.60; p 0.001), admission C-reactive protein level ≥18 mg/dL (OR 2.77, 95% CI 1.91-4.00; p <0.001) and admission creatinine level >1.5 mg/dL (OR 2.01, 95% CI 1.31-3.08; p 0.001) were risk factors for pulmonary complications. Complicated pneumonia was characterized by a more severe clinical presentation, but was not associated with increased mortality. Resistance to antibiotics was lower in complicated cases. No significant differences were observed in the serotype distribution between complicated and uncomplicated pneumonia. In the multivariate analysis, COPD was a protective factor against pulmonary complications.

Abstract
Infection is an important cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). This study was aimed at characterizing bloodstream infections in these patients and analysing factors associated with long term outcome. For this purpose, episodes of significant bacteraemia diagnosed from January 1991 to December 2006 among patients with SLE at a single centre were identified through a central database and clinical and analytical variables were recorded regarding short- and long-term follow-up. Univariate and multivariable analysis were performed to identify factors associated with long-term outcome. Thirty-eight SLE patients had 48 episodes of significant bacteraemia, with a 30-day mortality rate of 6.25%. Escherichia coli and Staphylococcus aureus were the leading Gram-negative and Gram-positive pathogens, respectively. After a median follow-up of 25 months, eight of these 38 patients (21.1%) had a further episode of bacteraemia and 13 of them (34.21%) died. Community-acquired bacteraemia and C reactive protein levels lower than 8 mg/dl during episodes were factors associated with lower long-term mortality. These results reinforce previous findings suggesting that lupus patients with bacteraemia episodes have poor long-term outcomes

Abstract
BACKGROUND Klebsiella pneumoniae is a well recognized source of nosocomial infection in solid-organ transplant (SOT) recipients. It is also the most common species capable of producing extended-spectrum β-lactamases (ESBL). Its treatment can therefore be a challenge owing to antibiotic resistance. METHODS Prospective study of all transplant recipients from July 2003 to December 2007 at our center. Klebsiellla pneumoniae infectious events were recorded. RESULTS A total of 1,057 patients were enrolled, 509 (48%) renal, 360 (34%) liver, 78 (7%) heart, and 110 (10%) double transplants. We diagnosed 116 episodes of K. pneumoniae infection in 92 patients during the study period, of which 62 were ESBL-producing strains (53%). Thirty-four episodes had bacteremia (29%), 15 of which were caused by ESBL-producing strains. There were no strains of K. pneumoniae producing carbapanemase (KPC). Forty-seven percent of the episodes occurred during the first month after transplantation. The incidence of infection by type of transplant was: renal 11%, liver 7%, cardiac 5%, and double transplant 6% (P=.075). The major sites of infection were urinary tract 72%, surgical wound 5%, intraabdominal 6%, catheter 5%, lung 1%, bloodstream 1%, and others 2%. ESBL-producing K. pneumoniae strains were more common in renal transplant patients (P=.035) and in those who required posttransplant dialysis (P=.022). There were 4 deaths in the first 30 days after the isolation of K. pneumoniae, and 3 of these cases were infections caused by ESBL-producing strains. CONCLUSIONS There was a high incidence of ESBL-producing K. pneumoniae infections in SOT recipients and renal transplant recipients, and those who required dialysis were more likely to develop infection by this strain. No KPC-producing organisms were found in our series. The existence of such a high level of resistance is a well recognized hospital threat, and appropriate policies and interventions should be addressed in high-risk patients.

Abstract
INTRODUCTION the aim of our study was to review the epidemiology and clinical manifestations of infections due to Panton-Valentine leukocidin-positive methicillin-resistant Staphylococcus aureus (PVL-MRSA). MATERIAL AND METHODS Medical history of patients infected by MRSA-PVL admitted to our hospital from January 2007 to July 2009 was reviewed. PVL and the type of cromosomic cassette were determined in all strains by PCR. RESULTS A total of 37 cases were included. Seventy percent were males and the median age was 39 years. Sixtytwo percent were Spanish, 14 (37.8%) were HIV-positive and 11 (29.7%) were homosexual. The source of the infection was the skin and soft tissue in 36 cases and pneumonia in 1. Sixteen patients were hospitalized, 5 had bacteremia and 5 developed septic metastasis. The relapse rate was 24% (9 cases). The prevalence during the study period was 11.2% of all MRSA isolated (37 out of 329). All the strains had a cromosomic cassette type IV and were susceptible to cotrimoxazole, rifampin, vancomyin, daptomycin and linezolid. The MIC of vancomycin, measured by E-test, was ≥ 1.5 mg/L in 28 out of 34 cases (82.3%). CONCLUSIONS Eleven percent of the MRSA strains isolated in our hospital are PVL positive. In general, skin and soft tissue infections are the most common and bacteremia or septic metastasis are frequent. In contrast to previous Spanish studies, more cases are observed in patients born in Spain and the infections are more severe.

Abstract
Objetivo. Evaluar los resultados funcionales de la trasferencia del palmar menor en los casos con atrofia tenar secundaria a síndrome del canal carpiano crónico.
Material y Método. Se revisan retrospectivamente 6 pacientes con una media de edad de 63 años e igual distribución en cuanto a género. En cuatro casos se trató de la mano dominante. Se registraron: el grado de atrofia, la movilidad del pulgar, y la fuerza. Se calcularon el DASH y el CTS y se registraron las complicaciones.
Resultados. Tras 45,7 meses de seguimiento medio, la abducción radial fue de 53,3º y todos lograron la oposición completa. Las pinzas pulpejo-pulpejo y pulpejo-lateral y la fuerza de puño fueron respectivamente del 75,1%, 96,6% y 96,8% respecto al lado contralateral. Se registró una mejoría significativa en los cuestionarios DASH y CTS siendo los valores del ES y SRM mayores de 0,8 en todos los casos.
Conclusiones. Creemos que la plastia de oposición de Camitz es una intervención simple, segura y efectiva que ayuda a mejorar la función de la mano en los casos de SCC crónicos graves, especialmente en pacientes mayores.

Abstract
Objetivo: La asociación de rizartrosis y síndrome del canal carpiano es frecuente. El objetivo de este estudio es valorar el resultado de la descompresión del canal carpiano a través de la vía utilizada para realizar la artroplastia de resección-suspensión del trapecio, así como discutir las ventajas e inconvenientes encontrados con esta técnica.
Material y método: Entre 2002 y 2006 se realizaron 16 artroplastias de resección-suspensión que presentaban un síndrome del canal carpiano asociado. Se valoró la resolución de la sintomatología mediante escala analógica visual, la recuperación de la fuerza de agarre de puño y las pinzas pulgar-índice, y la mejoría producida por la intervención en la calidad de vida de los pacientes utilizando la versión española de los cuestionarios DASH (Disabilities of the Arm, Shoulder, and Hand) y CTS (Carpal Tunnel Syndrome).
Resultados: Se revisaron 14 pacientes con un seguimiento medio de 23,7 meses (rango: 10-52). La sintomatología mejoró 8 puntos de media tras la intervención. La fuerza final de agarre de puño y de las pinzas pulpejo-lateral y pulpejo-pulpejo fueron 54,5%, 71,8% y 73,5% de los valores de referencia según edad, género y lado afecto.El cuestionario DASH mejoró 34,8 puntos, y el CTS 0,8 puntos para la valoración funcional y de 2,5 puntos para la gravedad de síntomas.
Discusión y conclusiones: Aunque el tratamiento del canal carpiano puede realizarse antes, durante o después de la cirugía de la artrosis trapecio-metacarpiana, para disminuir la morbilidad postoperatoria y la persistencia de síntomas se recomienda que ambas patologías sean tratadas en el mismo acto quirúrgico, y si fuera posible a través de la misma incisión. No alarga significativamente la intervención, permite una descompresión efectiva con mínima morbilidad y evita algunas de las complicaciones asociadas a la técnica tradicional.

Abstract
A greater rate of treatment failures with vancomycin in methicillin-resistant Staphylococcus aureus (MRSA) bacteremia has been reported recently when the minimum inhibitory concentration (MIC) is > or =2 mg/l. This study has aimed to evaluate if there are clinical and/or epidemiological factors that predict isolation of a MRSA strain with MIC of vancomycin of > or =2 mg/L in the bacteremia episodes collected during a 15 year period (January 1991 to December 2005) in a tertiary urban hospital. During the study period, a total of 478 episodes of MRSA bacteremia were studied prospectively. The following clinical variables were recorded for each one: age, gender, comorbidity, previous administration of vancomycin or another antibiotic, prognosis of baseline diseases, bacteremia focus, shock, empiric antibiotic received and mortality. The MIC of vancomycin of 419 strains (88%) was determined with the E-test. In 216 (52%) of the isolations the MIC of vancomycin was 1.50 mg/L, in 110 (26%) of the cases it was < or =1 mg/l and in 93 (22%) 2 mg/l. Uni-and multivariate analyses were made, comparing the clinical variables of the patients infected by strains with MIC of vancomycin > or =2 mg/l regarding the MIC strains < or =1 mg/l. In the last 3 years of the study (2003-2005) the proportion of the strains with MIC of vancomycin > or =2 mg/l was significantly greater than those isolated with MIC < or = 1 mg/L (44 % vs 3 %; p<0.001). In the multivariate analysis, the only clinical characteristic associated independently to the isolation of a strain with MIC > or =2 mg/l was the nosocomial-acquired infection OR (95 % CI): 1.94 (1.04-3.63); p=0.04. Although the isolation of a MRSA strain with MIC of vancomycin > or =2 mg/l is more frequent in the nosocomial-acquired bacteremia episodes, in the clinical practice, it is not a useful predictive parameter because the frequency of isolation of these strains in the community is also high.

Abstract
Increasing prevalence of infections caused by multiresistant gram-negative enteric bacilli due to synthesis of extended-spectrum beta-lactamase (ESBL) or to desrepressed chromosomic AmpC beta-lactamase (AmpC) is a major concern in the hospitalized patient population. Renal transplant recipients are especially susceptible to these infections. A cohort observational study in a 3-year period was performed. ESBL-production was determined by phenotypic analysis based on the CLSI recommendations. A multi-variate logistic regression analysis was performed to identify independent variables associated with multi-resistant gram-negative bacilli infection. The study included 417 patients (61 double kidney-pancreas recipients). The incidence of ESBL-producing and desrepressed chromosomic AmpC beta-lactamase resistance was 11.8% (49 patients). The most frequent bacteria isolated was E. coli (35/60 isolations), followed by Klebsiella spp(12/60 isolations). Double kidney-pancreas transplantation(OR 3.5, CI95% 1.6-7.8), previous use of antibiotics(OR 2.1,CI95% 1.1-4.1), posttransplant dialysis requirement (OR 3.1, CI95% 1.5-6.4) and posttransplant urinary obstruction (OR 5.8, CI95% 2.2-14.9) were independent variables associated with these multiresistant gram-negative enteric bacilli infections. The incidence of ESBL-producing and desrepressed AmpC beta-lactamase gram-negative enteric bacilli infection in our population was high. These infections are associated with significant morbidity after renal transplantation.

Abstract
Introducción: Los fibrolipomas de los nervios periféricos, o hamartomas lipofibromatosos, son tumores benignos que infiltran el espacio entre los fascículos neurales. Son más frecuentes en el territorio nervio mediano. La resonancia magnética ofrece un diagnóstico patognomónico. El tratamiento debe ser descompresivo cuando la escisión microquirúrgica no sea posible sin ocasionar secuelas funcionales.
Caso clínico: Varón de 30 años, trabajador manual, sin alteraciones morfológicas en sus manos con clínica de hipoestesia en 4º y 5º dedos, pérdida de fuerza en mano, atrofia hipotenar e interósea y principio de garra cubital de 8 meses de evolución. La electromiografía realizada indicó compresión del nervio cubital a nivel del canal de Guyon. En el acto quirúrgico se comprobó la existencia de un fibrolipoma del nervio cubital que comprometía a sus ramas terminales sensitiva y motora. Al no ser posible la exéresis microquirúrgica sin dañar al nervio, se realizó biopsia y descompresión amplia del nervio, mejorando la sintomatología del paciente.

Abstract
Three differentially expressed cDNAs have been isolated from ozone treated tomato seedlings. Their level of expression after ozone exposure has been analysed in three tomato cultivars with different sensitivity to ozone (Nikita, Alisa Craig and Valenciano). These comparative analyses have been extended to a number of genes involved in antioxidative, wounding or pathogenesis responses, showing several differences among cultivars that could be related with their different sensitivity to ozone. Gene response to ozone was affected not only by the period and dose of ozone exposure (short time or chronic), but also by growth conditions (controlled growth chamber or field). Comparison of gene expression patterns puts on evidence the needing of validation in field of experiments performed with plants grown under controlled conditions. Our results suggest that changes in genes expression, observed after ozone treatment in field, are affected by additional factors related to environmental clues.

Abstract
Objetivo: Valoración de los resultados obtenidos en pacientes con rizartrosis, en estadios iniciales, tratados mediante la tenotomía de los tendones accesorios del abductor pollicis longus, según técnica de Zancolli.
Material y Método: Entre 2002 y 2006 se han intervenido 23 casos: 13 tipo I, 7 tipo II y 3 tipo III de la clasificación de Zancolli. La edad media fue de 50,3 años, siendo el 95,7% mujeres; el 60,9% de los casos afectaba a la mano derecha. En un 82,6% de los casos la tenotomía de los tendones accesorios se realizó en el contexto del tratamiento de otra patología asociada. Se midió el dolor mediante la escala analógica visual, la movilidad del pulgar, la fuerza de prensión y de las pinzas pulgar-índice mediante dinamómetros Jamar y B&L, la progresión radiológica de la artrosis, la existencia de complicaciones y la mejoría de la calidad de vida mediante la versión española del cuestionario DASH.
Resultados: Tras un seguimiento medio de 46 meses se valoraron 18 pacientes. El dolor disminuyó 2,8 puntos, la abducción radial media fue de 41,2º, la fuerza media de la pinza pulpejo-pulpejo fue del 52,7% de la esperada, la pulpejo-lateral del 64,2%, y la de puño del 36,5%. En el estudio radiológico final encontramos una progresión radiológica de la enfermedad en 8 casos (44,4%), obteniendo una mejoría de 16,7 puntos en el DASH.
Discusión y Conclusiones: Con esta técnica se consigue una mejoría del dolor, pero no parece existir una disminución significativa en la progresión radiológica de la enfermedad a medio-largo plazo, salvo para algunos estadios muy iniciales. Puede ser útil en estadios prerradiológicos en los que ha fracasado el tratamiento conservador, o como gesto quirúrgico asociado cuando se vaya a intervenir al paciente por otra patología de la mano.

Abstract
BACKGROUND Mutiresistant bacterial infections are an emerging problem in the nosocomial setting. Our objectives were to describe the incidence, outcome, and risk factors for acquisition of multiresistant bacteria among renal transplant recipients. METHODS We prospectively followed patients undergoing kidney transplantation over a 3-year period. We collected demographic features, underlying chronic diseases, and main transplant characteristics and complications. Multiple antibiotic resistance was defined for the most important bacteria: Enteric gram-negative bacilli resistant to betalactamics, cephalosporins, and quinolones; Staphylococcus aureus resistant to methicillin, cotrimoxazole, and clindamcin; Enterococcus spp resistant to ampicillin and quinolones; nonfermentator bacilli resistant to all antibiotics except aminoglycosides and collistin. RESULTS Overall, 416 patients included 65 double transplants (62 kidney-pancreas and three kidney-liver) of mean age 48.5 years, and 57% men. Infection with multiresistant bacteria was observed in 58 patients (14%). Most frequent multiresistant bacteria were: Escherichia coli (n = 33), Klebsiella spp (n = 15), Citrobacter spp (n = 8), Enterobacter spp (n = 5), Morganella morganii (n = 2), Pseudomonas aeruginosa (n = 16), Acinetobacter baumanii (n = 2), Enterococcus spp (n = 9) and methicillin-resistant S. aureus (MRSA, n = 2). Age greater than 50 years, hepatitis C virus infection, double kidney-pancreas transplantation, requirement for posttransplant hemodialysis, surgical reoperation, and requirement for nephrostomy were independent variables associated with multiresistant bacterial infection. Most used antibiotics for treatment were: carbapenems (65%), amikacin (12%), linezolid, piperacillin-tazobactam, vancomycin, collistin, and fosfomycin. Infection with multiresistant bacteria was associated with a worse prognosis (graft loss or death, 19% vs 8%, P = .009). CONCLUSIONS The incidence of infection with multiresistant bacteria in our renal transplant cohort was high, being most frequently cephalosporin-resistant enteric gram-negative bacilli and multiresistant P aeruginosa. Methicillin-resistant S. aureus incidence was low. Infection with multiresistant bacteria conferred a worse prognosis.

A total of 1,640 community-acquired bacteremia cases in nonneutropenic adults were consecutively enrolled from January 2003 to May 2006 and prospectively followed up. Nonconditional logistic regression methods were used with PB and death as dependent variables. Secondary bacteremia (SB) was present in 1,440 patients, and 200 (12%) cases were PB. The independent factors associated with PB were male sex (OR 1.69, 95%CI 1.27-2.25, P = 0.001) and an ultimately or rapidly fatal prognosis for an underlying disease (OR 2.48, 95%CI 1.84-3.34, P = 0.001). The most frequently isolated microorganisms in PB were E. coli and other enterobacteria (26 and 22%, respectively) and S. aureus (15%). There were 28 and 37% ciprofloxacin-resistant E. coli strains in SB and PB, respectively (P = 0.2). Mortality was significantly higher in PB cases (13 vs 8%, P = 0.04). The independent factors associated with mortality in PB were ultimately or rapidly fatal prognosis of underlying disease (OR 2.1, 95%CI 1.41-3.13, P = 0.001), lack of fever at the moment of bacteremia (OR 2.38, 95%CI 1.18-4.76, P = 0.02) and incorrect empirical antibiotic therapy (OR 2.01, 95%CI 1.22-3.33, P = 0.006). The initial empiric antibiotic treatment was more frequently incorrect in PB than in SB, and this was a predictive factor for mortality in PB. The resistance pattern of E. coli, other enterobacteria and S. aureus in every setting should guide the most appropriate empirical treatment for PB.

Abstract
Time-to-positivity is useful in the diagnosis of catheter-related bacteraemia and as a predictor of an endovascular source in patients with Staphylococcus aureus bacteraemia. However, this parameter has been evaluated for only a limited number of microorganisms. In the present study, time-to-positivity was recorded for 1872 episodes of significant monomicrobial bacteraemia diagnosed at a teaching hospital during a 2-year period, and the associated microbial and clinical variables were investigated. According to multivariate analysis, Streptococcus pneumoniae, beta-haemolytic streptococci, Escherichia coli, Klebsiella, Enterobacter, Citrobacter and Aeromonas were characterised by fast growth, with an endovascular source, shock, liver cirrhosis and neutropenia also predicting a short time-to-positivity. For patients not receiving appropriate antibiotics, detection of Gram-positive cocci in clusters within 14 h was predictive of Staph. aureus; a time-to-positivity of >21 h ruled out the possibility that a Gram-positive organism in chains was a beta-haemolytic streptococcus or Strep. pneumoniae, and a time-to-positivity of < or =12 h meant that it was very unlikely that a Gram-negative bacillus was a non-fermenter. A time-to-positivity of < or =8 h was predictive of a non-urinary tract source in patients with E. coli bacteraemia, and detection of growth within 13 h predicted an endovascular source in those with Staph. aureus bacteraemia. In conclusion, time-to-positivity depended on the microorganism, original source and clinical variables involved. Although this measurement may provide some early clues concerning the microorganisms involved and the source of bacteraemia, its clinical impact remains to be defined.

Abstract
In order to gather more data on the use of teicoplanin for reducing MRSA infections in high-risk populations, the present study was conducted. At a hospital in Barcelona, Spain, there was a high prevalence of MRSA infections among patients who underwent surgery for femoral neck fracture during the first 5 months of 2002 (period A) when cefuroxime was the antibiotic prophylaxis. During the following 12 months (period B) 600 mg of teicoplanin was added to cefuroxime. The rates of overall and MRSA infection during period A were 5.07 and 2.73%, respectively. Pulsed-field gel electrophoresis demonstrated there was no clonal relationship among MRSA strains. No nasal carriers of MRSA were detected among health workers. During period B the rates of overall and MRSA infection were 2.36 and 0.19%, respectively. Both rates were statistically significantly lower than those in period A (p<0.05). These results suggest teicoplanin may be useful in patients undergoing orthopedic surgery when the prevalence of MRSA is high.

Abstract
OBJECTIVE To investigate whether there is a possible viral transmission using mesenchymal stem cells (MSCs) in autologous or allogeneic transplantation in the context of osteoarthritis (OA) patients. The presence of parvovirus B19 (B19), varicella zoster virus (VZV), and human herpesvirus-6 (HHV-6) was studied in MSCs from bone marrow of patients with OA and healthy controls. METHODS MSCs were prepared from bone marrow aspirates obtained from 18 patients undergoing joint replacement as a result of OA and from 10 healthy controls. DNA was extracted from primary MSCs' culture established from these cells and quantitative real-time polymerase chain reaction was performed to analyse the prevalence and viral load of B19, VZV and HHV-6. RESULTS The prevalence of total viral DNA among patients with OA was 16.7% (3/18), with a mean viral load of 29.7 copies/microg of DNA. One out of 18 was positive for B19 (viral load, 61.2 copies/microg of DNA), two for VZV (mean viral load, 14.4 copies/microg of DNA), and none for HHV-6. The prevalence of total viral DNA in the control group was 20% (2/10), with a mean viral load of 13.4 copies/microg of DNA. Both positive results were of B19 parvoviruses. There were no statistically significant differences among patients and controls. CONCLUSIONS This first approach to the viral prevalence in MSCs of bone marrow in OA patients and healthy controls seems to show a very low risk of viral transmission or reactivation in a possible MSCs' transplantation.

Abstract
BACKGROUND Few data are available on the clinical features of patients who develop breakthrough bacteraemia, understood as positive blood cultures despite appropriate antibiotic therapy. OBJECTIVES To determine the clinical significance and outcome of a large series of breakthrough bacteraemia. DESIGN Retrospective analysis of a prospectively collected database. SETTING Two university-affiliated hospitals in Catalonia, Spain. SUBJECTS A total of 392 individuals who suffered an episode of breakthrough bacteraemia recorded between 1997 and 2002. INTERVENTIONS Demographic characteristics, underlying diseases, origin of infection, sources of infection, microorganisms isolated, McCabe and Jackson prognostic criteria, and mortality were analysed. RESULTS Breakthrough bacteraemia was detected in 392 of 6324 (6.1%) episodes of bacteraemia. Eighty per cent of episodes were nosocomial. The most frequent source of infection in breakthrough bacteraemia was endovascular (70%). Coagulase-negative staphylococci, Staphylococcus aureus, and Pseudomonas aeruginosa were the most significant microorganisms involved. Nosocomial acquisition together with selected sources (central venous catheter, endocarditis and other endovascular foci), underlying conditions (neutropenia, polytraumatism, allogenic bone marrow and kidney transplantation), and particular microbial aetiologies (S. aureus, P. aeruginosa and polymicrobial) were independently associated with increased risk for developing breakthrough bacteraemia. Crude mortality rate was greater in patients with breakthrough bacteraemia (16% vs. 12.3%; P<0.05), and this condition was an independent predictor of death (OR 1.4, 95% CI, 1-1.9; P=0.04). CONCLUSIONS In view of a case of breakthrough bacteraemia it is mandatory to search for an endovascular focus. Empiric treatment should be directed to cover S. aureus, coagulase-negative staphylococci and nonfermentative Gram-negative bacilli. Breakthrough bacteraemia is an independent predictor of death.

Abstract
PURPOSE To describe clinical features and outcomes of enterococcal left-sided native valve endocarditis and to compare it to endocarditis caused by other pathogens. SUBJECTS AND METHODS Patients in the International Collaboration on Endocarditis-Merged Database were included if they had left-sided native valve endocarditis. Demographic characteristics, clinical features, and outcomes were analyzed. Multivariable analysis evaluated enterococcus as a predictor of mortality. RESULTS Of 1285 patients with left-sided native valve endocarditis, 107 had enterococcal endocarditis. Enterococcal endocarditis was most frequently seen in elderly men, frequently involved the aortic valve, tended to produce heart failure rather than embolic events, and had relatively low short-term mortality. Compared to patients with non-enterococcal endocarditis, patients with enterococcal endocarditis had similar rates of nosocomial acquisition, heart failure, embolization, surgery, and mortality. Compared to patients with streptococcal endocarditis, patients with enterococcal endocarditis were more likely to be nosocomially acquired (9 of 59 [15%] vs 2 of 400 [1%]; P <.0001) and have heart failure (49 of 107 [46%] vs 234 of 666 [35%]; P = 0.03). Compared to patients with S. aureus endocarditis, patients with enterococcal endocarditis were less likely to embolize (28 of 107 [26%] vs 155 of 314 [49%]; P <.0001) and less likely to die (12 of 107 [11%] vs 83 of 313 [27%]; P = 0.001). Multivariable analysis of all patients with left-sided native valve endocarditis showed that enterococcal endocarditis was associated with lower mortality (odds ratio [OR] 0.49; 95% confidence interval [CI] 0.24 to 0.97). CONCLUSIONS Enterococcal native valve endocarditis has a distinctive clinical picture with a good prognosis.

Abstract
Information about the in vitro effect of combinations of anti-staphylococcal agents on staphylococci is scarce. The aim of the study was to evaluate the in vitro activity of linezolid, moxifloxacin, levofloxacin, clindamycin and rifampin, alone or in combination, against Staphylococcus spp. Two Staphylococcus aureus and two Staphylococcus epidermidis strains isolated from blood cultures were studied using the killing curve method. The combinations analyzed were linezolid+moxifloxacin, linezolid+levofloxacin, linezolid+clindamycin, linezolid+rifampin, moxifloxacin+rifampin, moxifloxacin+clindamycin, levofloxacin+rifampin and levofloxacin+clindamycin. The following concentrations (mg/l) were used: 8 and 16 for linezolid, 2 for moxifloxacin, 3 for levofloxacin, 2 for clindamycin and 2 and 5 for rifampin. The activity was considered synergistic when a reduction in growth of at least 2 log(10) was produced with the combination in comparison to the most active antibiotic alone; antagonistic when a growth of at least 2 log(10) was produced with the combination in comparison to the most active antibiotic alone; and indifferent if the variation was less than 1 log(10). Linezolid and clindamycin were bacteriostatic, while moxifloxacin and levofloxacin were bactericidal. Rifampin was bacteriostatic against S. aureus and bactericidal against S. epidermidis. Linezolid and clindamycin reduced the bactericidal activity of levofloxacin and moxifloxacin, however an antagonistic effect was only observed against S. aureus. Other combinations of linezolid, rifampin, clindamycin, levofloxacin or moxifloxacin were indifferent. Linezolid and clindamycin antagonize the bactericidal activity of fluorquinolones against staphylococci. There was no difference between any other combinations against either S. aureus or S. epidermidis.
