Infección pulmonar por micobacterias no tuberculosas / Lung infection with nontuberculous mycobacteria

Objetivo: Describir la epidemiología y hallazgos en tomografía computarizada (TC) de las infecciones pulmonares por micobacterias no tuberculosas (IPMNT) y su evolución según el tratamiento. Material y métodos: Estudio retrospectivo de 131 pacientes consecutivos con cultivos positivos para micobacterias no tuberculosas (MNT) entre 2005 y 2016. Se seleccionaron los que cumplían con los criterios diagnósticos de IPMNT. Se analizaron los datos epidemiológicos, clínicos, microbiológicos, radiológicos, el tratamiento recibido y la evolución en función de este. Resultados: Se incluyeron 34 pacientes con una edad media de 55 años, el 67,6% hombres. El 50% estaba inmunodeprimido (VIH positivos, el 58,8%); el 20,6% tenía EPOC; el 5,9%, neoplasias conocidas; el 5,9%, fibrosis quística; y el 29,4% no presentaba comorbilidades. El 20,6% presentaba antecedentes de tuberculosis y el 20,6% estaba infectado por otros microorganismos. Mycobacterium avium complex fue el germen más frecuentemente aislado (52,9%). Siete pacientes (20,6%) presentaron además infecciones por otros microorganismos. En la TC, los hallazgos más frecuentes fueron: nódulos (64,7%), patrón en árbol en brote (61,8%), nódulos centrolobulillares (44,1%), consolidaciones (41,2%), bronquiectasias (35,3%) y cavidades (32,4%). Se realizó un estudio comparativo de los hallazgos entre hombres y mujeres y entre pacientes inmunodeprimidos e inmunocompetentes. El 67,6% recibió antituberculostáticos (el 72% mostró mejoría) y el 20,6%, antibióticos convencionales (todos con mejoría radiológica). Conclusión: El diagnóstico de la IPMNT es complejo. Los hallazgos clínicos y radiológicos son inespecíficos y un porcentaje importante de pacientes puede presentar otras infecciones concomitantes.(AU)

Objective: To describe the epidemiology and CT findings for nontuberculous mycobacterial lung infections and outcomes depending on the treatment. Material and methods: We retrospectively studied 131 consecutive patients with positive cultures for nontuberculous mycobacteria between 2005 and 2016. We selected those who met the criteria for nontuberculous mycobacterial lung infection. We analyzed the epidemiologic data; clinical, microbiological, and radiological findings; treatment; and outcome according to treatment. Results: We included 34 patients (mean age, 55 y; 67.6% men); 50% were immunodepressed (58.8% of these were HIV+), 20.6% had COPD, 5.9% had known tumors, 5.9% had cystic fibrosis, and 29.4% had no comorbidities. We found that 20.6% had a history of tuberculosis and 20.6% were also infected with other microorganisms. Mycobacterium avium complex was the most frequently isolated germ (52.9%); 7 (20.6%) were also infected with other organisms. The most common CT findings were nodules (64.7%), tree-in-bud pattern (61.8%), centrilobular nodules (44.1%), consolidations (41.2%), bronchiectasis (35.3%), and cavities (32.4%). We compared findings between men and women and between immunodepressed and immunocompetent patients. Treatment was antituberculosis drugs in 67.6% of patients (72% of whom showed improvement) and conventional antibiotics in 20.6% (all of whom showed radiologic improvement). Conclusion: The diagnosis of nontuberculous mycobacterial lung infections is complex. The clinical and radiologic findings are nonspecific and a significant percentage of pateints can have other, concomitant infections.(AU)

Patología aórtica no urgente: diagnóstico clínico-radiológico de la aortitis / Nonurgent aortic disease: clinical-radiological diagnosis of aortitis

Aortitis es un término patológico que designa la inflamación de la pared aórtica, independientemente de su causa. Su presentación clínica es inespecífica y variable, con síntomas como dolor abdominal, fiebre y pérdida de peso. También pueden estar elevados los reactantes de fase aguda. Un amplio espectro de entidades puede ocasionar aortitis, desde procesos infecciosos hasta enfermedades autoinmunes (de las que las más frecuentes son la arteritis de Takayasu y la arteritis de células gigantes), cuyo pronóstico y tratamiento son muy variables. Son varias las técnicas de imagen que permiten evaluar tanto la luz como la pared vascular (como la tomografía computarizada multidetector, la resonancia magnética, la angiografía o la PET-TC). Esta revisión se centra en las enfermedades más frecuentes que provocan aortitis y en los hallazgos clínicos y radiológicos más relevantes que ayudan a diagnosticar y tratar adecuadamente esta entidad (AU)

Aortitis is a pathological term designating inflammation of the aortic wall, regardless of its cause. The clinical presentation of aortitis is nonspecific and variable. Symptoms include abdominal pain, fever, and weight loss; acute phase reactants may also be elevated. Aortitis can be caused by a wide spectrum of entities, including from infectious processes to autoimmune diseases (Takayasu arteritis and giant cell arteritis are among the most common of these causing aortitis), and the prognosis and treatment of these entities vary widely. Various imaging techniques can be used to evaluate the lumen and wall of the aorta (such as multidetector computed tomography, magnetic resonance imaging, angiography, or PET-CT). This review focuses on the most common diseases that cause aortitis and on the clinical and radiological findings that are most useful for diagnosing and treating this condition appropriately (AU)

Evaluation of the regular practice of breast cancer screening in a health area.

Breast cancer screening has proved to be efficacious only in clinical trials or structured programs. However, little is known of its effectiveness as a regular practice. This study is an assessment of breast cancer screening in regular practice in a Spanish area of 350,000 inhabitants through analysis of existing sources of information. It is evident that this screening is insufficient, inefficient, very variable, nonspecific, and probably ineffective, although there is insufficient information to prove it. The immediate implementation of a well-structured and accredited screening program is essential to overcome the current limitations.
