Microbiological Progress in Patients with Bronchial Infection with Pseudomonas aeruginosa Treated with Nebulised Colistin.

BACKGROUND: Inhaled antibiotics allow the delivery of higher drug concentrations at the site of infection without the systemic adverse effects observed with the use of parenteral or oral antibiotics. These antibiotics have shown to decrease the number of exacerbations, reduce bacterial load or improve pulmonary function in several chronic respiratory conditions. OBJECTIVES: The aim of this study was to describe changes in the bacteriology of sputum in patients with chronic bronchial infection with Pseudomonas aeruginosa treated with nebulised colistin. MATERIAL AND METHODS: All patients with chronical infection with P. aeruginosa treated with nebulised colistin attending a day care unit during a 5-year (January 2010 to December 2014) period were included. Repeated-measures t tests were used to assess whether the introduction of colistin was associated with changes in the number of exacerbations or the length of the hospitalisations. RESULTS: Treatment with colistin was associated with a decrease in the number of ambulatory exacerbations (1.87-1.1, p = 0.007), of hospital exacerbations (1.3-0.7, p = 0.010) and of length of stay (15.7-8.6 days, p = 0.005). There was no linear trend in the proportion of isolate Enterobacteriaceae, gram-positive cocci, Haemophilus influenzae or fungi. Isolation of Enterobacteriaceae within 1 year after the beginning of the treatment with nebulised colistin was associated with an increase in the number of ambulatory exacerbations (incidence rate ratio 1.99, 95% CI 1.05-3.79). CONCLUSIONS: Nebulised colistin was effective in the treatment of chronic infection with P. aeruginosa, and no significant changes in the microbiological evolution were observed. Isolation of Enterobacteriaceae within 1 year after the beginning of the treatment with nebulised colistin was associated with an increase in the number of exacerbations.

Effects of a multidisciplinary approach on the effectiveness of antiviral treatment for chronic hepatitis C.

UNLABELLED:  Background. Despite the introduction of direct antiviral agents, pegylated interferon remains the mainstay of treatment for chronic hepatitis C. However, pegylated interferon is associated with a high rate of severe adverse events and decreased quality of life. Specific interventions can improve adherence and effectiveness. We aimed to determine whether implementing a multidisciplinary approach improved outcomes in the treatment of chronic hepatitis C. MATERIAL AND METHODS: We analyzed consecutive patients treated with pegylated interferon plus ribavirin between August 2001 and December 2011. We compared patients treated before and after the implementation of a multidisciplinary approach in 2007. We compared the baseline demographic and clinical characteristics and laboratory findings between groups, and used bivariate logistic regression models to detect factors involved in attaining a sustained virological response, calculating the odds ratios with their respective 95% confidence intervals. To evaluate the effect of the multidisciplinary team, we fitted a multivariate logistic regression model to compare the sustained virological response after adjusting for unbalanced variables and predictive factors. RESULTS: We included 514 patients [228 (44.4%) in the pre-intervention cohort]. Age, viral genotype, previous treatment, aspartate transaminase, ferritin, and triglyceride were prognostic factors of sustained virological response. After adjusting for prognostic factors, sustained virological response was higher in the multidisciplinary cohort (58 vs. 48%, p = 0.038). Despite higher psychiatric comorbidity and age in the multidisciplinary cohort, we observed a trend toward a lower rate of treatment abandonment in this group (2.2 vs. 4.9%, p = 0.107). CONCLUSION: Multidisciplinary management of chronic hepatitis C improves outcomes.

Loss of control over eating: a description of the eating disorder/obesity spectrum in women.

GOALS: This study aimed to analyse the association, commonalities and differences between obesity and eating disorders (ED). METHOD: A total of 150 female patients [50 obese with bulimia nervosa (OB + BN), 50 obese with binge eating disorders (OB + BED), 50 obese without eating disorders (OB)] and 50 female healthy-eating/weight control (CG) volunteers participated in this study. ASSESSMENT: All participants were assessed by the Eating Disorders Inventory-2 (EDI-2), the Symptom Checklist-Revised (SCL-90-R) and the Temperament and Character Inventory-Revised. RESULTS: In general, all the groups differed significantly and showed linear trends (OB + BN > OB + BED > OB > CG) on general and eating psychopathology (SCL-90-R and EDI-2). Regarding personality traits, statistically significant differences across all four groups were found on Harm Avoidance and Self-Directedness. Whereas some symptoms were shared in extreme weight conditions, others were specifically related to ED. CONCLUSIONS: The presence of binge and purge symptomatology in obese patients is clinically relevant. These findings help to understand the relationship between Obesity and ED.

[Rizatriptan-induced liver toxicity. Report of a case]. / Hepatotoxicidad de rizatriptán. Descripción de un caso clínico.

Triptans are a class of drugs with proven efficacy in the acute treatment of migraine headache. The first component of these drugs was sumatriptan, with various derivatives subsequently emerging. Until now, there has only been one reported case of liver toxicity with zolmitriptan. We now present a case of hepatotoxicity related to another drug in this group: rizatriptan.

Factors related to survival in hepatocellular carcinoma in the geographic area of Sabadell (Catalonia, Spain).

BACKGROUND: hepatocellular carcinoma (HCC) is a very frequent tumor. Screening for the disease is effective, but the prognostic factors are difficult to evaluate. OBJECTIVES: 1. To determine epidemiological data and the clinical course of HCC in our setting. 2. To compare patient survival according to whether screening is performed or not. 3. To evaluate survival prognostic factors. PATIENTS AND METHODS: data on the epidemiology and clinical course of patients diagnosed with HCC were collected on a prospective basis (January 2004-December 2006). Two groups were considered according to whether screening had been performed (group A) or not (group B). RESULTS: a total of 110 patients were diagnosed with HCC (70% males). The most common etiology of cirrhosis was hepatitis C (56.1%), and 69% presented mild liver failure (Child-Pugh grade A). The median follow-up was 1.8 years. Fifty-one percent had been subjected to screening. The diagnosis of HCC was established by imaging techniques in 48.2% of the cases, and by histological criteria in 51.8%. The median tumor size was 23 mm in group A and 28 mm in group B (p = 0.005). Treatment with curative intent was provided in 72% of the cases in group A and in 48% in group B (p = 0.011). The median overall survival was 1.99 years -2.67 years in group A and 1.75 years in group B (p = 0.05). The multivariate analysis of overall survival showed the type of treatment (OR = 2.82 95%CI: 1.3-6.12, p = 0.009) and liver function (OR = 1.71 95%CI: 1.1-2.68, p = 0.020) to be independent predictors of survival. CONCLUSIONS: screening allows the diagnosis of smaller lesions and a higher percentage of curative treatments. The degree of liver function and the provision of curative treatment are independent predictors of survival.

[Long survival after resection of cranial metastases from hepatocellular carcinoma. Case report and review of the literature]. / Larga supervivencia tras resección de metástasis craneal de hepatocarcinoma. Descripción de un caso y revisión de la literatura.

The life expectancy of patients with hepatocellular carcinoma (HCC) has increased in the last few years due to recent treatment advances. However, extrahepatic metastases from tumors, previously described only occasionally, are becoming more frequent in clinical practice. The choice between an active or passive approach to these metastatic lesions can sometimes present clinicians with a difficult dilemma. We discuss the case of a male patient with multifocal HCC and cranial metastasis from a primary liver tumor and who, after surgery and radiotherapy over the metastatic lesion, has survived for more than 3 years.

[Spontaneous visits to the emergency service and hepatology day hospital by patients with liver cirrhosis]. / Análisis de las consultas espontáneas de enfermos cirróticos a urgencias y hospital de día de hepatología.

INTRODUCTION: Because of the current overload of emergency services, new units, such as day units, have had to be created. Liver cirrhosis (LC) is a chronic disease with frequent decompensations requiring medical attention. The aim of this study was to compare differences between emergency consultations in a hepatology day hospital (HDH) and in an emergency service (ES) among patients with LC. METHODS AND MATERIAL: We performed an observational prospective study. All patients with LC attending the HDH or ES from September 2007 to August 2008 were asked to complete a questionnaire. Demographic, clinical, and radiological variables were collected. RESULTS: There were 743 consultations, of which 62% involved the HDH. The mean age was 65±12 years, and the male/female ratio was 2:3. The most frequent diagnosis in the ES was hepatic encephalopathy (26.2% ES versus 6% HDH, p<0.001) followed by upper gastrointestinal hemorrhage (17.7% ES versus 0.6% HDH, p<0.001), while the most frequent diagnosis in the HDH was ascites (66.2% HDH versus 22.7% ES, p<0.001). The tests performed were as follows: blood analysis: 95% ES versus 60% HDH (p<0.01); radiology: 71% ES versus 11% HDH (p<0.01) and paracentesis: 51% ES versus 74% HDH (p<0.01). The mean length of stay in the ES was 21.3±121.5 hours compared with 3.3±2.4 hours in the HDH (p<0.001). A total of 53% of patients attended in the ES were hospitalized compared with 12% of those attended in the HDH (p<0.05). CONCLUSION: Patients with LC preferentially attend the HDH, where fewer tests are performed and the length of stay is shorter. The care provided in the HDH is appropriate and efficient.

Interferon and the fear of needles: a case report.

The treatment of viral hepatitis C infection uses a combination of pegylated interferon and ribavirin. Psychological preparation of the patient is vital to ensure adherence to the treatment. In our center, the nurse prepares this treatment according to an established educative protocol; however, some patients have special needs that require individualized attention. One such situation observed by the nurse is that the patients frequently admit to the fear of needle puncture (the peginterferon treatment is administered subcutaneously) and are unable to inject themselves. We describe a representative case and the care plan to manage the patient's fear so that the patient acquires confidence in his or her ability to self-inject. This facilitates autonomy and coresponsibility for the treatment, and the nurse can develop care approaches to combat the patient's fear of needles.

[Results of pegylated interferon and ribavirin for the treatment of chronic hepatitis C in clinical practice: a 5-year experience]. / Resultados del tratamiento con interferón pegilado y ribavirina para la hepatitis crónica por el virus C en la práctica clínica. Experiencia de 5 años.

INTRODUCTION: Numerous clinical trials have demonstrated the efficacy of treatment with pegylated interferon and ribavirin but little is known about the results obtained in clinical practice. OBJECTIVE: To evaluate treatment response and factors influencing the treatment of chronic hepatitis C in clinical practice. MATERIAL AND METHODS: Between August 2001 and December 2005, we treated 219 patients with pegylated interferon (alpha 2a -fixed dose, or alpha 2b, according to weight) and ribavirin. Patients with genotype 1 or 4 received treatment with pegylated interferon alpha 2a (180 microg/week) and ribavirin (1000 mg/day if body weight was <75 kg or 1200 mg/day if body weight was >75 kg) or interferon alpha 2b (1.5 microg/kg/week) and ribavirin (10.6 mg/kg/day) for 48 weeks. Patients with genotype 2 or 3 were treated for 24 weeks with the same regimen of pegylated interferon alpha-2a or alpha-2b, but with 800 mg of ribavirin divided in two daily doses. Sustained viral response was defined as absence of HCV-RNA 6 months after the end of treatment. RESULTS: A total of 219 patients were included (69% men; mean age 44+/-10). As epidemiological antecedents, 22.4% of the treated patients had previously consumed drugs parenterally and 22.4% had received blood transfusions before 1992. Forty-seven percent of the patients with liver biopsy had fibrosis bridges or established liver cirrhosis. The genotype was distributed as follows: 69.8% genotype 1, 4.1% genotype 2, 17.8% genotype 3, and 8.2% genotype 4. Of the 219 patients, 76 (35%) were treated with pegylated interferon alpha 2a and 143 (65%) with interferon alpha 2b. Analysis of response by genotype revealed that sustained viral response was obtained in 46% genotype 1, 88.9% genotype 2, 78.9% genotype 3, and 33.3% genotype 4. Univariate analysis showed that the only variable influencing sustained viral response was genotype. CONCLUSION: Treatment with pegylated interferon and ribavirin in clinical practice shows a similar pattern of sustained viral response to that obtained in clinical research. The main variable correlated with sustained viral response continues to be viral genotype.

Incidence, prevalence and clinical course of primary biliary cirrhosis in a Spanish community.

BACKGROUND AND AIMS: Primary biliary cirrhosis (PBC) is characterized by the autoimmune inflammatory response of small intrahepatic bile ducts. Prevalence in Spain is estimated as 61.9 cases per million inhabitants, whereas Northern Europe rates over 200 cases/million. Our objective was to determine the incidence and prevalence of PBC in our health area. MATERIAL AND METHODS: PBC was defined by the presence of abnormal liver tests (dissociated cholestasis) with positive antimitochondrial antibodies and/or compatible liver histology. Medical records from patients diagnosed between 1990 and 2002 were reviewed retrospectively. The following data were collected: diagnostic data, demographic and analytic data, liver histology and stage and treatment and disease outcome. RESULTS: In a population of 389 758 inhabitants, 87 patients were diagnosed with PBC. Mean age at diagnosis was 63.9+/-12.6 years. Eighty-four (96.6%) were women. Mean annual incidence was 17.2 per 10 inhabitants and the prevalence at the end of study was 195 per 10. Biopsy was performed in 71 (81.6%) patients, 61 of whom (86%) did not have fibrosis. Time of follow-up was 63.6+/-43.2 (2.28-153.9) months. CONCLUSION: Incidence and prevalence in our reference area are higher than in some Spanish areas, as per the results previously published; however, they are comparable with those obtained in Northern Europe and the US.

Effectiveness of treatment with nebulized colistin in patients with COPD.

OBJECTIVES: To analyze whether the introduction of nebulized colistin in patients with chronic obstructive pulmonary disease (COPD) and infection with Pseudomonas aeruginosa (PA) is associated with a decrease of the number and duration of severe exacerbations. MATERIALS AND METHODS: Thirty six patients with COPD and infection with PA treated with nebulized colistin attending a day hospital during a 5-year (January 2010-December 2014) period were prospectively included. Repeated-measures t-tests were used to assess whether the introduction of colistin was associated with changes in the number of exacerbations or the length of the hospitalizations, comparing for each patient the year prior to the introduction of colistin with the year after. RESULTS: After the introduction of colistin, the number of admissions decreased from 2.0 to 0.9 per individual year (P=0.0007), and hospitalizations were shorter (23.3 vs 10.9 days, P=0.00005). These results persisted when patients with and without bronchiectasis or with and without persistence of Pseudomonas were separately analyzed. No pre-post differences were detected in the number of exacerbations not requiring admission. CONCLUSION: Nebulized colistin seems associated with a strong decrease in the number and duration of hospitalizations due to exacerbation in patients with COPD and infection with PA. Clinical trials with a larger number of patients are needed in order to confirm these results.

Usefulness of indirect noninvasive methods in predicting progression to cirrhosis in chronic hepatitis C.

BACKGROUND AND AIMS: The ability of noninvasive methods to predict the development of cirrhosis has not been established. We evaluated the ability of three noninvasive methods [the Forns index, the aspartate aminotransferase-to-platelet ratio index (APRI), and the Non-Invasive Hepatitis-C-related Cirrhosis Early Detection (NIHCED) score] to determine the risk of developing cirrhosis in chronic hepatitis C. METHODS: Consecutive patients with chronic hepatitis C who had undergone liver biopsy between 1998 and 2004 were eligible. We used the three methods to evaluate patients at baseline and at follow-up (4-10 years later). When these methods yielded discordant or indeterminate results, a second liver biopsy was performed. Logistic regression models were fitted for each method to predict whether cirrhosis would appear and to predict long-term mortality from cirrhosis. RESULTS: We included 289 patients in our study. The mean scores at baseline and at follow-up, respectively, were as follows: Forns, 5.47 ± 1.95 and 6.56 ± 2.02; APRI, 1.1 ± 2.33 and 1.4 ± 1.53; and NIHCED, 7.79 ± 11.45 and 15.48 ± 15.28. The area under the receiver operating characteristic curve for predicting cirrhosis was 0.83 for Forns, 0.79 for APRI, and 0.76 for NIHCED. The sensitivity and specificity for predicting cirrhosis, respectively, were 75 and 71% for Forns (cutoff 4.7), 86 and 42% for APRI (cutoff 0.48), and 41 and 82% for NIHCED (cutoff 0). The area under the receiver operating characteristic curve for predicting mortality was 0.86 for Forns, 0.79 for APRI, and 0.84 for NIHCED. CONCLUSION: Indirect noninvasive markers could help identify patients with chronic hepatitis C at risk of progression to cirrhosis.

Factores relacionados con la supervivencia en el carcinoma hepatocelular en el área geográfica de Sabadell / No disponible

Introducción: el carcinoma hepatocelular (CHC) es un tumor muy prevalente. Su cribado es eficaz, pero los factores pronósticos son difíciles de evaluar. Objetivos: 1. Conocer datos epidemiológicos y evolución clínica en nuestra área. 2. Comparar la supervivencia de los pacientes según si seguían cribado o no. 3. Evaluar los factores pronósticos de supervivencia. Pacientes y métodos: se recogieron prospectivamente (enero 2004-diciembre 2006) datos epidemiológicos y evolución clínica de pacientes diagnosticados de CHC. Se estudiaron dos grupos en función del cribado (grupo A = cribado, grupo B = sin cribado). Resultados: 110 pacientes fueron diagnosticados de CHC (70% hombres). La etiología más frecuente de la cirrosis fue por virus C en 56,1%, eran Child A el 69%. El seguimiento mediano fue de 1,8 años. El 51% estaban en programa de cribado. El diagnóstico de CHC fue mediante pruebas de imagen en el 48,2% y 51,8% por criterios histológicos. El tamaño tumoral mediano fue 23 mm en el grupo A y de 28 mm en el B (p = 0,005). El tratamiento con intención curativa fue del 72% en el A y del 48% en el B (p = 0,011). La supervivencia global mediana fue de 1,99 años: grupo A. 2,67 años y grupo B 1,75 años (p = 0,05). El análisis multivariado de la supervivencia global evidenció que el tipo de tratamiento -OR = 2,82 (IC 95%: 1,3-6,12) (p = 0,009)- y la funcionalidad hepática -OR = 1,71 (IC 95%: 1,1-2,68) (p= 0,020)- predicen independientemente la supervivencia. Conclusiones: el cribado permite el diagnóstico de lesiones de menor tamaño y mayor porcentaje de tratamientos curativos. De forma independiente el grado de función hepática y la realización de un tratamiento curativo predicen la supervivencia(AU)

Introduction Because of the current overload of emergency services, new units, such as day units, have had to be created. Liver cirrhosis (LC) is a chronic disease with frequent decompensations requiring medical attention. The aim of this study was to compare differences between emergency consultations in a hepatology day hospital (HDH) and in an emergency service (ES) among patients with LC. Methods and material We performed an observational prospective study. All patients with LC attending the HDH or ES from September 2007 to August 2008 were asked to complete a questionnaire. Demographic, clinical, and radiological variables were collected. Results There were 743 consultations, of which 62% involved the HDH. The mean age was 65±12 years, and the male/female ratio was 2:3. The most frequent diagnosis in the ES was hepatic encephalopathy (26.2% ES versus 6% HDH, p<0.001) followed by upper gastrointestinal hemorrhage (17.7% ES versus 0.6% HDH, p<0.001), while the most frequent diagnosis in the HDH was ascites (66.2% HDH versus 22.7% ES, p<0.001). The tests performed were as follows: blood analysis: 95% ES versus 60% HDH (p<0.01); radiology: 71% ES versus 11% HDH (p<0.01) and paracentesis: 51% ES versus 74% HDH (p<0.01). The mean length of stay in the ES was 21.3±121.5hours compared with 3.3±2.4hours in the HDH (p<0.001). A total of 53% of patients attended in the ES were hospitalized compared with 12% of those attended in the HDH (p<0.05).Conclusion Patients with LC preferentially attend the HDH, where fewer tests are performed and the length of stay is shorter. The care provided in the HDH is appropriate and efficient (AU)

Objetivos: Describir la técnica y las complicaciones de la punción biopsia hepática ambulatoria (PBHA) realizada siguiendo un protocolo propio y compararlas con las biopsias con ingreso hospitalario. Comparar los costes de las dos modalidades de biopsia. Material y métodos: Desde enero de 2000 a enero de 2002, se han realizado 320 PBH en nuestro hospital, 250 de forma ambulatoria (PBHA). Para esta última modalidad, todos los pacientes cumplieron una serie de criterios mínimos de salud y de entorno social previamente establecidos. Se han registrado las complicaciones posprocedimiento. Se han calculado los costes económicos de las PBHA y PBH con ingreso. Resultados: La PBHA se realizó en 250 pacientes, 164 varones y 86 mujeres, con una edad media de 46 años. No existieron complicaciones en 160 (64%) pacientes. Existió dolor controlado con medicación en 78 (31,2%) y cuadro vagal en 8 (3,2%). Cuatro pacientes requirieron ingreso: dos hematomas subcapsulares autolimitados, un cuadro vagal prolongado y otro por no cumplir los criterios del protocolo. Se ha realizado PBH con ingreso en 50 varones y en 20 mujeres, con una edad media de 48 años. De las 70 PBH ingresadas, hubo cuatro complicaciones graves: un fallecimiento, dos hemoperitoneos y un hematoma subcapsular autolimitado. El coste unitario de las PBHA fue de 393,66 #E y de las PBH con ingreso fue de 528,71 A. Conclusiones: Si se siguen unas condiciones sociosanitarias mínimas, la PBHA es una prueba segura, que evita ingresos hospitalarios, lo que se traduce en una mayor confortabilidad de los pacientes y en un ahorro económico

Objectives: To describe the technique and complications of US-guided percutaneous liver biopsy performed on an outpatient basis accor-ding to our designated protocol, to compare these results with those performed on inpatients, and to compare the costs of biopsy in the two settings. Material and methods: From January 2000 to January 2002, 320 patients underwent liver biopsy at our hospital; 250 of these patients were treated on an outpatient basis. All patients undergoing liver biopsy on an outpatient basis fulfilled previously established health and social criteria. All post-procedural complications were recorded. Costs for liver biopsy performed on outpatients and inpatients were calculated and compared. Results: A total of 250 patients (164 males and 86 females; mean age: 46 yrs) underwent liver biopsy on an outpatient basis.No complications were observed in 160 (64%) patients. Pain treatable with medication was seen in 78 (31.2%) and vaso-vagal syncope in 8 (3.2%). Four patients required admission, two for self-limiting sub-capsular hematomas, one for prolonged vaso-vagal syncope, and another for failing to fulfill protocol criteria. A total of 70 patients (50 males and 20 females; mean age: 48 yrs) underwent liver biopsy on an inpatient basis. Serious complications were present in four cases: one death, two hemoperitoneum, and one self-limiting subcapsular hematoma. The mean cost of liver biopsy in outpatients was 393.66 #E vs. 528.71 A in inpatients. Conclusions: Provided minimal health and social criteria are met, outpatient percutaneous liver biopsy is safe. Performing liver biopsy on an outpatient basis can obviate hospital admission, resulting in greater convenience for patients and reduced costs

Predictores psicométricos del rendimiento académico en el proceso de admisión a la carrera de Medicina de la Facultad de Medicina de la UMSA / Psychometric predictors of the academic performance in the process of the Medical School UMSA

En la universidad Mayor de San Andrés, se ha hecho conciencia de la necesidad de complementar los exámenes de conocimiento de ingreso a la Facultad con los otros criterios que aporten más elementos para sopesar la disposición del postulante psrs formarse como médico. Especialmente en la carrera de medicina se hace relevante la consideración de un repertorio amplio de habilidades, destrezas, aptitudes, atributos personales que hacen al buen médico, en lo técnico y en lo humanístico. Se ha detectado que muchos estudiantes que ingresan en la UMSA, a la facultad de medicina, y más concretamente a la carrera de medicina, presenta mal rendimiento académico, altos índices de deserción académica (bien de materias o de la carrera misma) y un excesivo número de años promedio de permanencia tanto para el egreso como para la titulación. Por otra parte, es posible suponer que el reiterado fracaso académico disminuirá la autoestima y tolerancia a la fustración del alumnado de medicina, asociados a la falta de motivación y desidia en al aprendizaje, tambien reforzada por la actitud instigadora y poco estimulante de los docentes hacia los recargistas o repitentes por enesima vez. Por otra parte, la titulación tardía del profesional de medicina disminuye las posibilidades de postgrado, especialmente si ya el estudiante asumio la responsabilidad de una familia
