RESUMEN

La inmunoterapia con el bacilo Calmette-Guérin (BCG) es el agente intravesical más efectivo para el tratamiento de carcinoma vesical in situ tras la resección transuretral del tumor. Pese a ser un agente seguro y las complicaciones sistémicas son infrecuentes, las complicaciones locales leves son frecuentes. La afectación pulmonar es inusual (< 1%) suele ser grave, en forma de patrón micronodulillar y su mecanismo etiopatológico es controvertido. Se presenta el caso clínico de un varón con afectación pulmonar micronodulillar secundaria a instilaciones de BCG intravesical (AU)

Immunotherapy with Calmette-Guérin bacillus (BCG) is the most effective intravesical treatment of in situ bladder carcinoma besides the transurethral resection. Tough its known to be secure, and systemic complications are very rare, mild local complications are frequents. The lung involvement is unusual (< 1%), normally severe, with a micronodular pattern, and its etiopathogenic mechanism is a controversial issue. We present a case of a man with micronodular pattern secondary to intravesical BCG’s instillations (AU)

RESUMEN

OBJETIVO: El objetivo del estudio fue conocer la tendencia de las variables relacionadas con la tuberculosis (TB) en España a partir del registro del Programa Integrado de Investigación en Tuberculosis (PII-TB) de la Sociedad Española de Neumología y Cirugía Torácica (SEPAR) y evaluar el PII-TB mediante indicadores relacionados con sus objetivos científicos. MÉTODO: Estudio transversal multicéntrico de base poblacional de casos nuevos de TB registrados prospectivamente por el PII-TB entre 2006 y 2016. La tendencia temporal de variables cuantitativas se realizó mediante un modelo de regresión lineal y las cualitativas mediante la prueba de χ2 de tendencia lineal. RESULTADOS: Se analizaron 6.892 casos de TB con una mediana anual de 531. La tendencia general fue significativamente decreciente en mujeres, inmigrantes, privados de libertad y en tratados inicialmente con 3 fármacos. Se incrementaron significativamente la tendencia de grupos de 40 -50 años y > 50 años, primera atención por especialista de zona, hospitalización, retraso diagnóstico, localización diseminada y extrapulmonar única, cultivo (+), realización de antibiogramas, resistencia a fármacos, tratamiento directamente observado, prolongación del tratamiento y muerte por otra causa. Los objetivos científicos del PII-TB que incrementaron significativamente fueron las publicaciones alcanzando un máximo de 8 en 2016 y con un factor de impacto total de 49,664, y también mejoraron los proyectos iniciados anualmente, presentaciones en congresos y las tesis o tesinas. CONCLUSIONES: El PII-TB proporciona información relevante sobre la TB y sus factores asociados en España. Se ha formado un amplio equipo de investigadores y se han detectado aspectos científicos positivos y otros mejorables

OBJECTIVE: The objective of the study was to determine the trend of variables related to tuberculosis (TB) from the Integrated Tuberculosis Research Program (PII-TB) registry of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR), and to evaluate the PII-TB according to indicators related to its scientific objectives. METHOD: Cross-sectional, population-based, multicenter study of new TB cases prospectively registered in the PII-TB between 2006 and 2016. The time trend of quantitative variables was calculated using a lineal regression model, and qualitative variables using the χy test for lineal trend. RESULTS: A total of 6,892 cases with an annual median of 531 were analyzed. Overall, a significant downward trend was observed in women, immigrants, prisoners, and patients initially treated with 3 drugs. Significant upward trends were observed in patients aged 40-50 and > 50 years, first visit conducted by a specialist, hospitalization, diagnostic delay, disseminated disease and single extrapulmonary location, culture (+), sensitivity testing performed, drug resistance, directly observed treatment, prolonged treatment, and death from another cause. The scientific objectives of the PII-TB that showed a significant upward trend were publications, which reached a maximum of 8 in 2016 with a total impact factor of 49,664, numbers of projects initiated annually, presentations at conferences, and theses. CONCLUSIONS: PII-TB provides relevant information on TB and its associated factors in Spain. A large team of researchers has been created; some scientific aspects of the registry were positive, while others could have been improved

RESUMEN

BACKGROUND: Under-reporting of tuberculosis (TB) cases complicates disease control, hinders contact tracing and alters the accuracy of epidemiological data, including disease burden. The objective of the present study is to evaluate the proportion of unreported TB cases in Spanish healthcare facilities and to identify the associated factors. METHODS: A multi-center retrospective study design was employed. The study included TB cases diagnosed in 16 facilities during 2011-2012. These cases were compared to those reported to the corresponding public health departments. Demographic, microbiological and clinical data were analyzed to determine the factors associated with unreported cases. Associated factors were analyzed on a bivariate level using the x(2) test and on a multivariate level using a logistic regression. Odds ratios (OR) and 95 % confidence intervals (CI) were calculated. RESULTS: Of the 592 TB cases included in the study, 85 (14.4 %) were not reported. The percentage of unreported cases per healthcare center ranged from 0-45.2 %. The following variables were associated to under-reporting at a multivariate level: smear-negative TB (OR = 1.87; CI:1.07-3.28), extrapulmonary disease (OR = 2.07; CI:1.05-4.09) and retired patients (OR = 3.04; CI:1.29-7.18). A nurse case manager was present in all of the centers with 100 % reporting. The percentage of reported cases among the smear-positive cases was 9.4 % and 19.4 % (p = 0.001) among the rest of the study population. Smear-positive TB was no associated to under-reporting. CONCLUSIONS: It is important that TB Control Programs encourage thorough case reporting to improve disease control, contact tracing and accuracy of epidemiological data. The help from a TB nurse case manager could improve the rate of under-reporting.

RESUMEN

Pulmonary arterial hypertension and secondary pleural effusion have been reported in association with long-term therapy with the multi-tyrosine kinase inhibitor dasatinib, approved for the treatment of chronic myeloid leukemia. Here, we present the case of a 50-year-old man, diagnosed with chronic myeloid leukemia in August 2003, who developed pulmonary arterial hypertension after > 4 years of treatment with dasatinib. The complete remission of pulmonary arterial hypertension following dasatinib discontinuation suggests an etiological role of the drug in its development, although the administration of sildenafil may have played a therapeutic role.

RESUMEN

We present a case of pneumothorax associated with an endobronchial carcinoid tumor in a 18-year-old man with dyspnea and chest pain. Additional tests were done, identifying in the chest roentgenogram a complete left pneumothorax with persistent leak, which was confirmed by computed tomography of the chest, and also finding an endobronchial lesion that limited the complete reexpansion of the left lung. Surgical excision was performed, and the lesion was identified as a typical bronchial carcinoid, with satisfactory outcome after the intervention.
