RESUMO

La neumonía COVID ha supuesto un reto para la Neumología que ha respondido de forma rápida y con resultados muy satisfactorios a la demanda de soporte ventilatorio no invasivo que esta enfermedad y sobre todo la sobrecarga en las Unidades de Cuidados Intensivos ha ocasionado. En el caso de la Comunidad Autónoma de Madrid (CAM), la mayoría de los centros hospitalarios ampliaron o implantaron los recursos que facilitaron el uso de esta terapia para miles de pacientes que de otro modo no hubieran tenido la oportunidad de mejorar su situación respiratoria. Mediante este artículo queremos dar a conocer la visión global de esta intervención en 14 centros de la red de hospitales de la CAM (AU)


COVID pneumonia has been a challenge for Pulmonology that has responded quickly and with very satisfactory results to the demand for non-invasive ventilatory support that this disease and especially the overload in Intensive Care Units has caused. In the case of the Autonomous Community of Madrid (CAM), most hospitals expanded or implemented the resources that facilitated the use of this therapy for thousands of patients who otherwise would not have had the opportunity to improve their respiratory situation. Through this article we want to present the global vision of this intervention in 14 centers of the CAM network of hospitals (AU)

RESUMO

BACKGROUND: Organ transplantations cause discrepancy in results from cell-free DNA (cfDNA) testing, but scientific literature is scarce. CASE: A 33-year old gravida underwent cfDNA testing, which showed high levels of Y chromosome (ChrY) in the maternal bloodstream. The ChrY pattern was comparable to an adult male reference. As a result, cfDNA testing was only informative for autosomes. Routine 20-week ultrasound scan showed no structural alterations and the presence of female external genitalia. Post-clinical research revealed that the patient received a bone marrow transplant from a male donor several years before. Fluorescence in situ hybridization showed that 100% of nuclei analysed from the patient's lymphocytes presented a ChrY. CONCLUSION: This case demonstrates ChrY can be used as a marker to avoid sex discrepancies in certain patients with organ transplants.

RESUMO

The acquired von Willebrand Syndrome (AvWS) is a bleeding disorder with laboratory findings similar to those of the congenital form. Its presentation is more common in adults than in children and is mainly associated with lymphoproliferative and myeloproliferative diseases and rarely with autoimmune diseases including systemic lupus erythematosus (SLE). Here, we report the case of a girl with SLE and AvWS with mucosal bleeding and low plasma levels of von Willebrand factor and factor VIII (FVIII) with failure to respond to treatment with first- and second-line therapies. The patient finally responded to rituximab. To our knowledge this is the first reported case of SLE associated with AvWS, that responded to rituximab.

RESUMO

El diagnóstico diferencial de nódulos pulmonares cavitados constituye un gran desafo en el cual, la clínica, la imagenología y los exámenes de laboratorio permiten una orientación etiológica en cutro grandes grupos: infecciosa, neoplásica, reumatológica y miscelánea. Presentamos el caso de una paciente gran fumadora y portadora de una diabetes mellitus descompensada, con nódulos pulmonares cavitados, en la cual el contexto clínico obligaba a plantear ciertas etiologías como las infecciosas y neoplásicas, pero cuya biopsia fue compatible con Granulomatosis con Poliangeítis (ex Granulomatosis de Wegener), sin una clínica ni exámenes de laboratorio concordantes con dicho hallazgo.


The differential diagnosis of cavitary pulmonary nodules is a great challenge, where the clinical context in addition to the image studies and laboratory tests are part of the key tools to guide the diagnostic process through 4 major etiological groups: infectious, neoplastic, rheumatologic and miscellaneous. We describe a case of a heavy smoker and complicated diabetic patient with cavitary pulmonary nodules, with a clinical context that induces certain etiologies such as infectious and neoplastic, but whose biopsy was compatible with Granulomatosis with polyangiitis (ex Wegener 's granulomatosis), without a clinical exam nor laboratory tests suggesting this finding.

RESUMO

La enfermedad de Behçet (EB) es una patología inflamatoria vascular, multisistémica y recurrente. El fenómeno subyacente es una perivasculitis que afecta el territorio arterial y venoso. La mayor prevalencia de la enfermedad se encuentra en el Oriente y cuenca del Mediterráneo, en la llamada “Ruta de la Seda”. La prevalencia en Chile es desconocida. Las manifestaciones clínicas más frecuentes son úlceras orales y genitales recurrentes, uveítis, artritis, compromiso de sistema nervioso y vascular. El compromiso de SNC (Neuro-Behçet) varía entre 5 por ciento y 13 por ciento, y se divide en dos tipos: Intra-axial o parenquimatoso, más frecuente, más grave, con lesiones inflamatorias en tronco del encéfalo, en unión meso-diencefálica y región pontobulbar. Puede extenderse hacia diencéfalo, bulbo y médula espinal. El compromiso hemisférico es menos frecuente. Extra-axial, que se presenta como trombosis de senos venosos, y aneurismas, estenosis y disección arterial. El tratamiento del Neuro-Behçet intra-axial se basa en esteroides en dosis altas asociados a inmunosupresores, entre ellos, y dependiendo de la severidad, Metotrexato, Azatioprina, Ciclofosfamida, Micofenolato, y Anti-TNFα en casos refractarios o severos.


The highest prevalence of the disease is found in the East and the Mediterranean basin, in the so called “Silk Road”. The prevalence in Chile is unknown. The most frequent clinical manifestations are recurrent oral and genital ulcers, uveitis, arthritis, and CNS involvement (Neuro-Behçet). Neurological disease varies between 5 percent and 13 percent, and it can be divided into two types: Intra-axial or parenchymatous: more frequent, more severe, with inflammatory lesions involving the brainstem, midbrain, diencephalon and pontobulbar regions. It may extend into the spinal cord. Involvement of the brain hemispheres is less common. Extra-axial: also called “Neurovasculo Behçet”, less common and with better prognosis. It can manifests as venous sinus thrombosis, and aneurysm, stenosis, or arterial dissection of intracerebral or extracranial arteries. Treatment of Intra-axial Neuro-Behçet is based on high-dose steroids associated with immunosuppressive agents like: Methotrexate, Azathioprine, Cyclophosphamide, Mycophenolate, and anti α-TNF in refractory or severe disease.

RESUMO

Background: Smoking is noxious for health and is considered a public health priority. The prevalence of smoking is increasing, specially in women. Among nurses, its prevalence is 42.7 percent. Aim: To study the prevalence of smoking among Chilean nurses. Material and methods : A cross sectional analysis of the prevalence of smoking among 290 female nurses living in 9th Region of Chile. A nicotine addiction scale was applied to smokers. Results: The prevalence of smoking was 37.9 percent and the percentage of former smokers was 18.3 percent. Twenty percent of the sample was an occasional smoker. The starting age for the habit was between 17 and 20 years (49.4 percent). Twenty seven percent of nurses without children and 42 percent of those with children smoked. Having a couple or not, did not influence the smoking habit. Ninety percent of smokers had a very low addiction to nicotine. Conclusions : The prevalence of smoking obtained in a sample of nurses is similar to that obtained by former studies in other population samples in Chile

RESUMO

EEl trabajo analiza la situación funcional, mortalidad e institucionalización al año de los pacientes mayores de 60 años que sufrieron una fractura de cadera en el Área de Salud del Bierzo, comparando los resultados con otros trabajos, nacionales e internacionales, de diseño similar. Las fracturas de cadera determinan un factor muy importante de muerte llegando hasta el 24,2 por ciento al año y empeoramiento de la situación funcional del paciente mayor. Se observa una tendencia a una mayor tasa de mortalidad y peor recuperación funcional entre pacientes españoles frente a los de otros países más desarrollados, europeos o norteamericanos (AU)

RESUMO

We report the case of a 65-year-old man with no history of respiratory disease who came to the emergency room complaining of fever, cough, yellowish sputum and increasing dyspnea of one week's duration. Severe respiratory insufficiency was evident upon examination and a chest film showed diffuse pulmonary infiltrates. Microbiological tests were negative. Lung biopsy gave evidence consistent with diffuse alveolar damage in organizing phase. Evolution of symptoms and blood gases was good after corticosteroid treatment was begun, although pulmonary fibrosis was still evident in a follow-up radiograph.

RESUMO

Nódulo pulmonar solitario (NPS) es una entidad clínico-radiológica controvertida por su manejo, existiendo diferencias en el diagnóstico y tratamiento. Se presenta una revisión retrospectiva de pacientes operados con NPS en el Servicio de Cirugía Hospital Roy H. Glover de Chuquicamata; 18 pacientes, 13 hombres y 5 mujeres con edades promedio de 42,7 y 49,6 años respectivamente. El diagnóstico se realizó por Rx de Tórax en el 88 por ciento. El tamaño promedio fue 20 mm. Hubo 4 cánceres (2 adenocarcinomas y 2 escamosos) con promedio de 22,4 mm, 8 tuberculomas, hamartomas, 1 plasmocitoma y 1 fístula a-v. Predominó la localización en el lóbulo inferior izquierdo con 8 casos. La biopsia se obtuvo por toracotomía en 9 pacientes, VTC en 7, biopsia transparetial en uno y por biopsia transbronquial en una. Las resecciones pulmonares más frecuentes fueron en cuña en 9 casos, nodulectomía en 6, segmentectomía 2 y lobectomías más linfadenectomías en mediastínicas en 2. No hubo mortalidad y la morbilidad fue 11 por ciento. El porcentaje de lesiones malignas v/s benignas depende de la población seleccionada. En nuestra serie hubo un alto porcentaje de tuberculomas y lesiones malignas. La VTC es el procedimiento de elección en los NPS periféricos. Se recomienda una actitud agresiva en el manejo de esta patología por la alta tasa de mortalidad por cáncer pulmonar de la región que triplica la media nacional

RESUMO

Se presenta el caso de un varón de 65 años, sin enfermedades respiratorias previas, que acudió a urgencias por un cuadro de una semana de evolución de fiebre, tos, expectoración amarillenta y disnea progresivamente creciente. Presentaba una insuficiencia respiratoria grave en el momento de su evaluación. En la radiografía de tórax se evidenciaron infiltrados pulmonares difusos. Los estudios microbiológicos que se le realizaron fueron negativos. La biopsia pulmonar demostró la existencia de hallazgos consistentes con un daño alveolar difuso en fase de organización. A raíz del inicio del tratamiento esteroide, el paciente experimentó una evolución favorable, tanto clínica como gasométrica, persistiendo un patrón de fibrosis pulmonar en la radiografía de tórax de control.

RESUMO

The distribution of [111In]oxine-labeled leukocytes was studied by whole-body gamma camera imaging in nine pediatric patients. Images were obtained at approximately 24 hr after administration of the material. Organ distribution was estimated from stored data by manual region of interest assignment. Dosimetry estimates based on geometric mean and conjugate view absolute activity calculations showed close agreement in these patients. Leukocytes were distributed in liver, spleen and marrow. The mean percent uptakes +/- s.d. were: spleen, 31.2 +/- 18.3%; liver, 26.3 +/- 10.8%; and marrow, 14.2 +/- 5.7%. A significant portion (28.3 +/- 9.9%) of administered white cell activity was found outside these organs in the remainder of the body. Mean organ absorbed doses (rad/mCi) were: spleen, 115.0 +/- 84.8; liver, 13.9 +/- 7.8; marrow, 7.6 +/- 3.8; and total body 2.5 +/- 1.0. The mean organ absorbed doses (rad/dose administered) were: spleen, 13.7 +/- 10.6; liver, 1.48 +/- 0.62; marrow, 0.79 +/- 0.26; and total body, 0.28 +/- 0.09.
