Development of Aspergillosis in a cohort of non-neutropenic, non-transplant patients colonised by Aspergillus spp.

BACKGROUND: A previous study explored factors discriminating colonization and true infection among non-transplant, non-neutropenic patients with repeated Aspergillus spp. isolation from lower respiratory samples. The present study explored the evolution of patients with Aspergillus colonization in that study to determine the percentage of cases progressing to aspergillosis and time to development. METHODS: Clinical records were retrospectively reviewed (for each patient from his end date in the past study) and data from all respiratory processes suffered by patients up to April 2015 were recorded. Comparisons of variables were performed between colonized patients that developed aspergillosis and those that did not. A Kaplan-Meier curve was used to describe time to development of aspergillosis in chronic obstructive pulmonary disease (COPD) patients for II-IV stages of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification. RESULTS: Sixty seven colonized patients were followed, 12 of them (17.9%) developed aspergillosis. Diagnoses included six tracheobronchitis (4 invasive, 2 simple tracheobronchitis), four pulmonary disease (2 invasive pulmonary aspergillosis, 2 chronic pulmonary aspergillosis), one allergic bronchopulmonary aspergillosis and one pulmonary aspergilloma. Up to 47 (70.4%) of the study patients presented COPD. Among patients developing aspergillosis COPD was more frequent (100%) than among those that did not develop aspergillosis (35 out of 55; 63.6%) (p = 0.012), as well as GOLD IV patients were more frequent among COPD patients developing aspergillosis than among COPD patients that did not (50.0 vs. 26.1%, p = 0.046). Mean time to development of aspergillosis was 18.4 months (median: 8.5) with a wide range (1-58). Overtime, the percentage of patients developing aspergillosis was significantly higher among GOLD IV patients than among GOLD II-III patients (p = 0.032). CONCLUSIONS: The high percentage of cases progressing to aspergillosis among colonized patients, especially among those with COPD (25.5%), stresses the importance of colonization as risk factor, and creates awareness of the possible change from colonization to invasive disease in GOLD IV patients.

[The method of selection of the residents in Spain. Analysis of the examination MIR and offer of a new methodology]. / El método de selección de los residentes en España. Análisis del examen MIR y propuesta de una nueva metodología.

INTRODUCTION: The method for selecting medical graduates for residency positions has a strong influence on teaching and learning strategies in medical schools. The methodology currently used in Spain does not seem appropriate for ranking the candidates or improving curriculum development. Thus, and taking into account the most consistent methodologies used in the United Kingdom and USA, we have designed a new method to be used in our country. OBJECTIVES: To analyze the limitations of the methodology used in Spain, and propose a new one aimed to improve the accuracy of selection itself and avoiding the negative influence of the current method on curricular development. In addition, we emphasize the necessity of improving teaching and learning in the clinical context to assure that graduating students reach an adequate level of clinical competence. CONCLUSIONS: The method for selecting candidates to residency post currently used in Spain, which relies mainly on testing theoretical knowledge, should be changed for an alternative methodology taking into account student,s performance through the course and assessing his/her ability for clínical contextualization of knowledge and level of clinical competence.

[Selection of medical graduates for residency posts. A comparative study of the methodologies used in different countries]. / La selección de los graduados en Medicina para los puestos de residencia. Estudio comparativo de los métodos usados en diferentes países.

INTRODUCTION: The design of an appropriate method for the selection of medical graduates for residency posts is extremely important, not only for the efficiency of the method itself (accurate identification of most competent candidates), but also for its influence on the study and teaching methodologies operating in medical schools. Currently, there is a great variation in the criteria used in different countries and there is no definitively appropriate method. The use of isolated or combined criteria, such as the marks obtained by students in medical schools, their performance in tests of theoretical knowledge and evaluations of clinical competence, or personal interviews, have a limited value for identifying those candidates who will perform better during the residency and later on during independent practice. OBJECTIVES: To analyse the variability in the methodologies used for the selection of residents employed in different countries, in particular those used in the United Kingdom and USA, where external agencies and medical schools make systematic analyses of curriculum development. The advantages and disadvantages of national or transnational licensing examinations on the process of convergence and harmonization of medical degrees and residency programmes through Europe are discussed. The present analysis is used to design a new and more efficient multi-criteria methodology for resident selection in Spain, which will be published in the next issue of this journal. CONCLUSIONS: Since the multi-criteria methods used in UK and USA appear to be most consistent, these have been employed for designing the new methodology that could be applied in Spain. Although many experts in medical education reject national examinations for awarding medical degrees or ranking candidates for residency posts, it seems that, when appropriately designed, they can be used to verify the level of competence of graduating students without necessarily distorting curriculum implementation or improvement.

Repeated Aspergillus isolation in respiratory samples from non-immunocompromised patients not selected based on clinical diagnoses: colonisation or infection?

BACKGROUND: Isolation of Aspergillus from lower respiratory samples is associated with colonisation in high percentage of cases, making it of unclear significance. This study explored factors associated with diagnosis (infection vs. colonisation), treatment (administration or not of antifungals) and prognosis (mortality) in non-transplant/non-neutropenic patients showing repeated isolation of Aspergillus from lower respiratory samples. METHODS: Records of adult patients (29 Spanish hospitals) presenting ≥ 2 respiratory cultures yielding Aspergillus were retrospectively reviewed and categorised as proven (histopathological confirmation) or probable aspergillosis (new respiratory signs/symptoms with suggestive chest imaging) or colonisation (symptoms not attributable to Aspergillus without dyspnoea exacerbation, bronchospasm or new infiltrates). Logistic regression models (step-wise) were performed using Aspergillosis (probable + proven), antifungal treatment and mortality as dependent variables. Significant (p < 0.001) models showing the highest R2 were considered. RESULTS: A total of 245 patients were identified, 139 (56.7%) with Aspergillosis. Aspergillosis was associated (R2 = 0.291) with ICU admission (OR = 2.82), congestive heart failure (OR = 2.39) and steroids pre-admission (OR = 2.19) as well as with cavitations in X-ray/CT scan (OR = 10.68), radiological worsening (OR = 5.22) and COPD exacerbations/need for O2 interaction (OR = 3.52). Antifungals were administered to 79.1% patients with Aspergillosis (100% proven, 76.8% probable) and 29.2% colonised, with 69.5% patients receiving voriconazole alone or in combination. In colonised patients, administration of antifungals was associated with ICU admission at hospitalisation (OR = 12.38). In Aspergillosis patients its administration was positively associated (R(2) = 0.312) with bronchospasm (OR = 9.21) and days in ICU (OR = 1.82) and negatively with Gold III + IV (OR = 0.26), stroke (OR = 0.024) and quinolone treatment (OR = 0.29). Mortality was 78.6% in proven, 41.6% in probable and 12.3% in colonised patients, and was positively associated in Aspergillosis patients (R2 = 0.290) with radiological worsening (OR = 3.04), APACHE-II (OR = 1.09) and number of antibiotics for treatment (OR = 1.51) and negatively with species other than A. fumigatus (OR = 0.14) and aspergillar tracheobronchitis (OR = 0.27). CONCLUSIONS: Administration of antifungals was not always closely linked to the diagnostic categorisation (colonisation vs. Aspergillosis), being negatively associated with severe COPD (GOLD III + IV) and concomitant treatment with quinolones in patients with Aspergillosis, probably due to the similarity of signs/symptoms between this entity and pulmonary bacterial infections.

A predictive score at admission for respiratory failure among hospitalized patients with confirmed 2019 Coronavirus Disease: a simple tool for a complex problem.

Coronavirus Disease 2019 (COVID-19) pandemic has implacably stricken on the wellness of many countries and their health-care systems. The aim of the present study is to analyze the clinical characteristics of the initial wave of patients with COVID-19 attended in our center, and to identify the key variables predicting the development of respiratory failure. Prospective design study with concurrent data retrieval from automated medical records of all hospitalized adult patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rRT-PCR assay performed on respiratory samples from March 2nd to 18th, 2020. Patients were followed up to May 1st, 2020 or death. Respiratory failure was defined as a PaO2/FiO2 ratio ≤ 200 mm Hg or the need for mechanical ventilation (either non-invasive positive pressure ventilation or invasive mechanical ventilation). We included 521 patients of whom 416 (81%) had abnormal Chest X-ray on admission. Median age was 64.6 ± 18.2 years. One hundred eighty-one (34.7%) developed respiratory failure after a median time from onset of symptoms of 9 days (IQR 6-11). In-hospital mortality was 23.8% (124/521). The modeling process concluded into a logistic regression multivariable analysis and a predictive score at admission. Age, peripheral pulse oximetry, lymphocyte count, lactate dehydrogenase and C-reactive protein were the selected variables. The model has a good discriminative capacity with an area under the ROC curve of 0.85 (0.82-0.88). The application of a simple and reliable score at admission seems to be a useful tool to predict respiratory failure in hospitalized COVID-19 patients.

Non-alcoholic fatty liver disease in patients with intestinal, pulmonary or skin diseases: Inflammatory cross-talk that needs a multidisciplinary approach.

Non-alcoholic fatty liver disease (NAFLD) is currently considered the most common cause of liver disease. Its prevalence is increasing in parallel with the obesity and type 2 diabetes mellitus (DM2) epidemics in developed countries. Several recent studies have suggested that NAFLD may be the hepatic manifestation of a systemic inflammatory metabolic disease that also affects other organs, such as intestine, lungs, skin and vascular endothelium. It appears that local and systemic proinflammatory/anti-inflammatory cytokine imbalance, together with insulin resistance and changes in the intestinal microbiota, are pathogenic mechanisms shared by NAFLD and other comorbidities. NAFLD is more common in patients with extrahepatic diseases such as inflammatory bowel disease (IBD), obstructive syndrome apnea (OSA) and psoriasis than in the general population. Furthermore, there is evidence that this association has a negative impact on the severity of liver lesions. Specific risk characteristics for NAFLD have been identified in populations with IBD (i.e. age, obesity, DM2, previous bowel surgery, IBD evolution time, methotrexate treatment), OSA (i.e. obesity, DM2, OSA severity, increased transaminases) and psoriasis (i.e. age, metabolic factors, severe psoriasis, arthropathy, elevated transaminases, methotrexate treatment). These specific phenotypes might be used by gastroenterologists, pneumologists and dermatologists to create screening algorithms for NAFLD. Such algorithms should include non-invasive markers of fibrosis used in NAFLD to select subjects for referral to the hepatologist. Prospective, controlled studies in NAFLD patients with extrahepatic comorbidities are required to demonstrate a causal relationship and also that appropriate multidisciplinary management improves these patients' prognosis and survival.

[Bronchioloalveolar carcinoma in Spain: a rare and different form of lung cancer]. / Carcinoma bronquioloalveolar en España. Un cáncer de pulmón infrecuente y diferente.

OBJECTIVE: To describe a series of cases of bronchioloalveolar carcinoma (BAC) treated surgically between 1993 and 1997 in the 19 hospitals that make up the Bronchogenic Carcinoma Cooperative Group of the Spanish Society of Pulmonology and Thoracic Surgery (GCCB-S). PATIENTS AND METHODS: From a total of 2,944 cases of non-small cell lung cancer (NSCLC), 82 (3%) were BAC. The clinical characteristics and prognosis of patients with BAC were compared with those of the remaining 2,862 patients with NSCLC. RESULTS: The percentage of men was lower for BAC than for other types of NSCLC (64.6% compared with 93.5%; P< .001) and BAC was associated with less comorbidity (50% vs 62%; P< .05), particularly in terms of chronic obstructive pulmonary disease (33% vs 47.2%; P< .05). Other characteristics showing significant differences were the higher frequency of BAC as a chance finding and the lower likelihood of weight loss or reduced performance status at the time of diagnosis. Classification as stage cI was significantly more common in patients with BAC (87% vs 75%; P.001), and this difference between groups was more pronounced for stage pI (68.5% vs 47%; P< .01). Only taking into account patients classified as stage pI with complete resection of NSCLC and following exclusion of operative mortality, patients with BAC presented an overall 5-year survival of 65% (95% confidence interval [CI], 51%-79%), compared with a significantly lower survival of 53% (95% CI, 50%-56%; P< .05) in patients with other forms of NSCLC. CONCLUSIONS: In Spain, among cases of lung cancer treated by surgery, BAC is very rare (3%) and displays clinical characteristics that are different from other forms of NSCLC. Controlling for the most basic prognostic factors (stage pI and complete resection), survival is significantly higher for BAC.

Primary pulmonary lymphoma: diagnosis and follow-up of 6 cases and review of an uncommon entity.

AIMS AND BACKGROUND: Primary pulmonary lymphoma is an uncommon disease with a poorly defined management. We reviewed and followed the cases of primary pulmonary lymphoma in our institution to gather an estimation of this entity in our population. DESIGN AND METHODS: We reviewed the records of all patients with biopsy-proven lymphoma of the lung. The main diagnostic criterion for primary pulmonary lymphoma was the absence of extrapulmonary involvement. RESULTS: We identified 6 cases of primary pulmonary lymphoma among 33 patients with biopsy-proven lymphoma of the lung evaluated in our center in a 12-year period. A radiological abnormality in an asymptomatic patient was the most common clinical presentation. Four cases were low-grade and two cases high-grade non-Hodgkin PPL. Histopathologic analyses of lung specimens obtained by transbronchial biopsy were sufficient for a diagnosis in 5 of the 6 cases and avoided invasive surgical maneuvers. Most patients followed an indolent course, but with a tendency to relapse. CONCLUSIONS: Although clinical management of this entity is undefined, we feel bronchoscopic study, which is less aggressive than surgery, may be an adequate procedure for a diagnosis. Mono-chemotherapy using alkylating agents and careful clinical observation may be the best therapeutic approach for these patients, since most of them have favorable outcomes, whatever the treatment modalities.

Interferon gamma levels in pleural fluid for the diagnosis of tuberculosis.

PURPOSE: To assess the utility of interferon gamma levels, including identification of the best cutoff for the diagnosis of tuberculosis. METHODS: We prospectively studied consecutive patients in a tertiary care, university-affiliated hospital who had pleural effusions. Interferon gamma levels were measured blindly by radioimmunoassay. The diagnosis of tuberculosis was established using prespecified standard criteria. RESULTS: Of the 595 patients with pleural effusions, 82 patients (14%) had tuberculosis. The area under the receiver operating characteristic (ROC) curve for elevated interferon gamma levels in the diagnosis of tuberculosis was 0.99 (95% confidence interval [CI]: 0.97 to 1.00). A cutoff of 3.7 IU/mL yielded a sensitivity of 0.98 (95% CI: 0.91 to 1.00) and a specificity of 0.98 (95% CI: 0.96 to 0.99). The areas under the ROC curves, and the test's sensitivity and specificity, were similar among patients of different ages and by percentage of lymphocytes in the pleural fluid. In 5 of the 28 patients with hematologic malignancies, interferon gamma levels were slightly above the cutoff; no patient with vasculitis or granulomatous diseases had levels higher than 3.7 IU/mL. The 14 immunocompromised patients and the 3 transplantation patients with tuberculosis had interferon gamma levels greater than the cutoff. CONCLUSION: Elevated pleural interferon gamma levels (>3.7 IU/mL) are very valuable in diagnosing pleural tuberculosis. Patients with pleural effusion due to hematologic neoplasms occasionally have levels slightly above the cutoff.

Clinical implications of appearance of pleural fluid at thoracentesis.

STUDY OBJECTIVES: The aims of this study were to describe the different appearances of pleural fluid during thoracentesis and their frequency in relation to diagnosis, and to evaluate the causes and clinical implications of bloody pleural effusions. SETTING: Tertiary care, university-affiliated hospital. SUBJECTS AND METHODS: Seven hundred fifteen patients with pleural effusion were prospectively assessed from December 1991 to December 1997. INTERVENTIONS: The appearance of the fluid was assessed in a glass assay tube containing 10 mL of pleural fluid. RESULTS: The most common presentations were serous and blood tinged, with 80% of the fluids fitting into one of these categories. The most frequent cause of watery fluid was transudate, although most transudates were classified as serous effusions. There were 59 bloody and 656 nonbloody pleural fluids. The most common cause of bloody pleural effusion (BPE) was malignancy (47%). Fluid with a bloody appearance slightly increased the probability of malignancy in our series (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.01 to 2.94; p = 0.04). Nevertheless, only 11% of the neoplastic effusions were BPE. Other common causes of BPE were posttraumatic (12%) or parapneumonic (10%) pleural effusions. Tuberculosis and transudates were uncommon causes of BPE. Fluid that was bloody in appearance decreased the probability for both diseases (OR, 0.15; 95% CI, 0.04 to 0.57; p = 0.003 and OR, 0.25; 95% CI, 0.06 to 0.95; p = 0.04, respectively). CONCLUSIONS: Serous and blood tinged were the most common presentations of pleural fluid at thoracentesis. Almost half of BPEs were secondary to neoplasms, but only 11% of the neoplastic effusions were BPEs. Other common causes of BPE were parapneumonic and posttraumatic.

Amylase levels in pleural effusions: a consecutive unselected series of 841 patients.

STUDY OBJECTIVES: To describe the causes and relative frequency of amylase-rich pleural effusion (ARPE), and to study the origin and histologic type of the tumors with ARPE, the strength of the association between ARPE and the result of pleural cytology, and whether pleural amylase (PA) is a prognostic factor in the survival of patients with a malignant pleural effusion. SETTING: Tertiary-care, university-affiliated hospital. PATIENTS: Eight hundred forty-one consecutive patients with pleural effusion prospectively assessed from 1991 to 1999. RESULTS: There were 66 ARPEs: 40 neoplastic, and 26 benign with tuberculosis, pancreatitis, and liver cirrhosis as the most frequent causes. Thirty-six percent of patients in our series and 61% of patients with ARPE had a neoplastic disease (odds ratio [OR], 3; p < 0.001); this association got much stronger for cases with PA levels > or = 600 IU/L (95th percentile); [OR, 10; p < 0.001]. The most frequent tumor origin was lung cancer (13 cases). Adenocarcinoma was the most frequent histologic type (18 cases). Two mesothelioma effusions were ARPEs. There was a positive association between ARPE and the finding of tumor cells in pleural fluid (OR, 2.79; p < 0.01). In the malignant group, PA levels > or = 600 IU/L identified a group of patients with quite a short median survival (p = 0.016). CONCLUSIONS: The most common cause of ARPE was neoplasm. There was a positive association between ARPE and malignancy, stronger with the highest levels (95th percentile). Lung cancer and adenocarcinoma were the most common tumor and histologic type associated with ARPE. Mesothelioma may also produce ARPE. There was an association between ARPE and the finding of tumor cells in the pleural fluid. The highest PA levels identified a group of patients with a median shorter survival.

Endobronchial hamartoma.

OBJECTIVES: To describe clinical, endoscopic, radiographic, and follow-up characteristics of a series of patients in whom endobronchial hamartoma (EH) had been diagnosed. METHODS: Retrospective study of all cases of hamartoma diagnosed by bronchial biopsy between 1974 and 1997 in a tertiary referral hospital in Madrid, Spain. RESULTS: EH was diagnosed 47 patients during the study period. Four patients were excluded from the study because no clinical history was available. We analyzed the cases of 43 patients (37 men and 6 women), with a mean (+/- SD) age of 62 +/- 12 years. Seven patients had a concurrent lung neoplasm, and the EH was an incidental endoscopic finding. Among the other 36 patients, 31 had a new onset of respiratory symptoms, most commonly, recurrent respiratory infections in 16 patients (44%) and hemoptysis in a further 12 patients (33.4%). Chest radiograph findings were abnormal in 38 of 43 patients. At bronchoscopy, the lesions were equally distributed throughout the right and left lungs with no clear lobar predilection. Endobronchial obstruction was evident in 26 patients (72.2%) without concurrent neoplasm, 17 of whom underwent resection with a rigid bronchoscope and laser, with total resolution in 13 patients. Partial resolution was achieved in four patients, two of whom needed a second endoscopic procedure. Five patients were treated with open lung surgery. Clinical and endoscopic follow-up was performed in 23 patients at 1 to 73 months (mean, 17 months), and recurrence was found in 4 patients. CONCLUSION: EH frequently produces respiratory complaints and radiographic abnormalities. Patients with endobronchial obstructions had satisfactory responses to endoscopic therapy.

Diagnostic value of CA 549 in pleural fluid. Comparison with CEA, CA 15.3 and CA 72.4.

Several tumor markers have been evaluated in pleural fluid, but their clinical role has not been firmly established. The aim of this study is to determine the diagnostic value of carbohydrate antigen 549 (CA 549) levels in pleural fluid, and to compare it with another previously studied tumor markers: carcinoembryonic antigen (CEA), CA 15.3 and CA 72.4. We prospectively studied 252 patients with pleural effusion: 101 malignant (20 mesothelioma) and 151 of several benign diseases. The levels of the tumor markers were measured by immunoradiometric assays (RIA). CA 549 in pleural fluid has an acceptable sensitivity (0.49), with high specificity (0.99). The best combination of tumor markers for differentiating malignant from benign effusions was CA 549+CEA+CA 15.3, with a sensitivity of 0.65, specificity of 0.99 and accuracy of 0.85. The addition of any one tumor marker assay consistently improved the diagnostic value of cytology. In our study, none of the tumor markers was organ-specific. When mesothelioma and hematological malignancy were ruled-out, the combination of CA 549+CEA+CA 15.3, improved the results up to a sensitivity of 0.77, specificity of 1 and accuracy of 0.92. In conclusion, CA 549 assay has an acceptable sensitivity with high specificity. The best combination of tumor markers in this series with a high relative frequency of mesothelioma and low frequency of breast carcinoma was CA 549+CEA+CA 15.3. Individual tumor markers or their combination increased the sensitivity of pleural cytology.

Report on the incidence of interstitial lung diseases in Spain.

BACKGROUND AND AIM OF THE WORK: Almost no epidemiological data are available on a worldwide basis on the prevalence, incidence or relative frequency of interstitial lung diseases (ILD). We report the results of a registration of ILD by 23 centers of pulmonary medicine in Spain over one year (from October 2000 to September 2001). METHODS: A standardized questionnaire was sent to the centers, together with guidelines for classification and diagnostic evaluation. This questionnaire included questions about the explorations performed to establish the diagnosis. RESULTS: A total of 511 cases were registered. The mean age of the patients was 61 +/- 0.7 (x +/- SEM) yrs. The male to female ratio was 1.2:1. The estimated incidence of ILD was 7.6 per 100,000/year. The most frequent disease was idiopathic pulmonary fibrosis (38.6%), followed in decreasing order by sarcoidosis (14.9%), cryptogenic organizing pneumonia (10.4%), ILD associated with collagen vascular diseases (9.9%) and hypersensitivity pneumonitis (6.6%). In 5.1% of cases ILD was unclassified. HRCT scan was performed in 91.9% of cases, bronchoalveolar lavage in 67.9%, transbronchial lung biopsy in 59.9%, and surgical lung biopsy in 22.7%. CONCLUSIONS: This registration provides interesting information on the occurrence of ILD in Spain and on the procedures used to establish the diagnosis.

La enseñanza de la práctica clínica en la Facultad de Medicina de la Universidad Complutense de Madrid / Teaching of clinical practice in the Faculty of Medicine of the Complutense University of Madrid

Se describe la metodología de instrucción y evaluación en práctica clínica y el grado de implicación del profesorado en esta tarea en la Unidad Docente del Hospital 12 de Octubre (Facultad de Medicina, Universidad Complutense de Madrid). A pesar de algunas disfunciones curriculares, nuestros estudiantes alcanzan un buen nivel de competencia clínica al final del grado. Algunos profesores tienen un conocimiento limitado de los roles docentes que pueden asumir, por lo que deberían recibir formación específica. Idealmente, la enseñanza clínica ha de implicar a todos los profesionales que cuidan del paciente en el contexto extra- e intrahospitalario

We describe the methodology for instruction and assessment of clinical practice and analyze the profile and teaching roles of faculty at the Teaching Unit of the Hospital 12 de Octubre (Faculty of Medicine, Complutense University of Madrid). Despite some structural limitations in curriculum development our students reach a good final level of clinical competence. The need for trainers to understand the different roles they can assume, improving faculty development and involving all the professionals taking care of the patient in the teaching process are emphasized

Examen clínico objetivo y estructurado formativo tras inmersión clínica precoz empleando estudiantes de sexto curso como observadores y administradores de retroalimentación / Formative objective structured clinical examination following early clerkships using sixth-year students as examiners and feed-back providers

Introducción: En este artículo se describen la logística y los resultados de un examen clínico objetivo y estructurado (ECOE) formativo pasado a estudiantes de tercero expuestos a un curso de transición del periodo básico al clínico y a rotaciones clínicas precoces, en el que utilizamos estudiantes de sexto curso como observadores y administradores de la retroalimentación. Materiales y métodos: Se analizan el rendimiento de los candidatos, la correlación de las puntuaciones otorgadas con listados de ítems y una escala global de la competencia usados por el paciente estandarizado y el estudiante observador, así como el grado de aceptación de la prueba por parte de todos los participantes. Resultados: Los estudiantes observadores se sintieron altamente satisfechos con su tarea de observación y administración de la retroalimentación. Los profesores valoraron con puntuaciones altas la tarea de los estudiantes observadores, y los alumnos candidatos otorgaron igualmente puntuaciones altas a la actuación de los estudiantes observadores, la calidad de la retroalimentación recibida y la logística del ECOE. El rendimiento global en el ECOE superó el 70,1%. Se observó una buena correlación entre las puntuaciones otorgadas por los dos observadores (enfermo y estudiante) con los dos instrumentos de medida (listados y escala global). Conclusiones: Los estudiantes del último curso del grado son capaces de usar de manera fiable los listados de ítems y una escala global de la competencia, y de proporcionar retroalimentación adecuada en un ECOE formativo. La exposición clínica precoz al inicio del tercer curso en un currículo 3 + 3 motiva y prepara a los estudiantes para el aprendizaje posterior en las rotaciones del periodo clínico

Introduction: We describe the logistic and results of a formative objective structured clinical examination (OSCE) designed with the double aim of providing feedback to third-year students given by senior students, and assessing clinical skills of the candidates who were exposed to a short transition course and early clerkships. Materials and methods:Candidates performance, the correlation between the scores given by standardized patients and students examiners using checklists and a global rating scale, as well as the acceptance of the OSCE by all participants were analyzed. Results: Faculty members considered excellent the action of student examiners including the feedback they gave to candidates. Student examiners felt much satisfied observing and giving feedback to candidates. Candidates valued highly the action of student examiners, the quality of the feedback they received, and the logistic of the OSCE. Global performance in the OSCE was 70.1%. The correlation between the scores given by the two examiners using checklists and the global rating scale was good. Conclusions: Senior students are able to use checklists and a global rating scale in a reliable manner and to provide appropriate feedback at a formative OSCE. A transition course followed by an early clinical immersion motivate and prepare students for learning during the clinical period in our 3 + 3 curriculum

[Failure of levofloxacin therapy in two cases of community-acquired pneumonia caused by fluoroquinolone-resistant Streptococcus pneumoniae and complicated with empyema]. / Fracaso terapéutico de levofloxacino en dos casos de neumonía adquirida en la comunidad complicada con empiema causados por Streptococcus pneumoniae resistente a fluoroquinolonas.

BACKGROUND: Community acquired pneumonia (CAP) due to Streptococcus pneumoniae is a frequent cause of morbidity and mortality. We communicate two cases of CAP with complications. In both cases levofloxacin-resistant S. pneumoniae was isolated in pleural effusion. Patient 1: A 51-year-old man who had not received previous treatment with quinolones was admitted to the hospital for CAP and initially treated with levofloxacin (500 mg/24h iv). Four days later pleural effusion developed and fluid culture isolated levofloxacin-resistant S. pneumoniae (MIC > 32 .g/ml). The outcome was favorable following chest tube placement and treatment with beta-lactam antibiotics. Patient 2: A 73-year-old man with a history of chronic obstructive pulmonary disease was admitted due to CAP and was initially treated with levofloxacin (500 mg/24 h iv). He was transferred to our hospital after 10 days of treatment with this antibiotic, following the development of pleural effusion with isolation of levofloxacin-resistant S. pneumoniae (MIC = 12 .g/ml). The patient was treated with chest tube placement and beta-lactam antibiotics with a favorable outcome. CONCLUSIONS: Patients with CAP treated empirically must be closely followed, both clinically and radiologically, to facilitate early detection of complications due to bacterial resistance to the prescribed antibiotic. Patients with CAP who have received quinolones in the weeks before the development of pneumonia should not been treated empirically with these antibiotics because of the risk of resistance development.

La selección de los graduados en Medicina para los puestos de residencia. Estudio comparativo de los métodos usados en diferentes países / Selection of medical graduates for residency posts. A comparative study of the methodologies used in different countries

Introducción: El diseño de una metodología apropiada para la selección de los graduados que acceden a los puestos de residencia tiene gran importancia porque, aparte de su eficiencia en la elección de los candidatos, condiciona decisivamente el funcionamiento curricular en las escuelas de medicina, incluyendo la manera de estudiar y aprender del estudiante y la actitud docente del profesorado y su motivación para perseguir la innovación curricular. En la actualidad existe una gran dispersión en los métodos de selección de los residentes en diferentes países, evidenciando que no hay ninguno perfecto. El uso aislado de criterios tales como el peso del expediente académico, los test de conocimiento teórico, determinadas pruebas prácticas de la competencia clínica, o las entrevistas tienen un valor limitado para predecir qué candidatos van a ser más competentes durante la residencia o la práctica autónoma. Objetivos: Describir las metodologías utilizadas para la selección de los residentes en los países de nuestro entorno prestando especial atención a las empleadas en el Reino Unido y los EE. UU. donde se analiza de manera sistemática el funcionamiento de los currícula en las escuelas de medicina. Se comentan las ventajas y desventajas de los exámenes de ámbito nacional para otorgar el grado y/o construir el listado de acceso a la residencia, y su utilidad para favorecer el proceso de convergencia y armonización de los grados y los programas de residencia a nivel transnacional europeo o internacional. El presente análisis se utiliza para establecer una comparación con la metodología de selección aplicada actualmente en España en un intento de diseñar un nuevo método multicriterio más eficiente que se describirá en otro artículo publicado en el próximo número de esta revista Conclusiones: Los métodos multicriterio para la selección de los residentes en el Reino Unido y los EE. UU. parecen los más consistentes por lo que serán utilizados para construir el nuevo método que podría ser aplicado en España. Aunque muchos expertos en docencia médica rechazan los exámenes de ámbito nacional para otorgar el grado y/o establecer el orden de acceso a los puestos de residencia porque limitan la diversidad y la innovación curriculares, cuando están bien diseñados sirven para verificar el alcance del nivel mínimo aceptable de competencia clínica del graduado sin distorsionar el buen funcionamiento y la mejora progresiva del currículum

Introduction: The design of an appropriate method for the selection of medical graduates for residency posts is extremely important, not only for the efficiency of the method itself (accurate identification of most competent candidates), but also for its influence on the study and teaching methodologies operating in medical schools. Currently, there is a great variation in the criteria used in different countries and there is no definitively appropriate method. The use of isolated or combined criteria, such as the marks obtained by students in medical schools, their performance in tests of theoretical knowledge and evaluations of clinical competence, or personal interviews, have a limited value for identifying those candidates who will perform better during the residency and later on during independent practice. Objectives: To analyse the variability in the methodologies used for the selection of residents employed in different countries, in particular those used in the United Kingdom and USA, where external agencies and medical schools make systematic analyses of curriculum development. The advantages and disadvantages of national or transnational licensing examinations on the process of convergence and harmonization of medical degrees and residency programmes through Europe are discussed. The present analysis is used to design a new and more efficient multi-criteria methodology for resident selection in Spain, which will be published in the next issue of this journal. Conclusions: Since the multi-criteria methods used in UK and USA appear to be most consistent, these have been employed for designing the new methodology that could be applied in Spain. Although many experts in medical education reject national examinations for awarding medical degrees or ranking candidates for residency posts, it seems that, when appropriately designed, they can be used to verify the level of competence of graduating students without necessarily distorting curriculum implementation or improvement
