Abstract: the severity and duration of post chemotherapy neutropenia were recognized during the 1960s as main predisposing factors for infections in cancer patients. at the beginning of the 70’s a standard management approach for all febrile neutropenia (fn) episodes was proposed, based on hospitalization and intravenous empirical broad spectrum antibiotic therapy. widespread use of this approach resulted in a significant reduction in mortality attributable to bacterial infections. during the last 10 to 15 years, reappraisal of this standard approach has been done by several research groups who question the benefit of treating all fn patients similarly without taking in to consideration differences in severity of the fn episodes. this reappraisal has led during the 1990s to the development of the concept of high and low risk fn episodes that has been the base for the adoption of selective therapies based on the risk categorization of the individual patient. the chilean infectious diseases society called upon two government national programs responsible for the appropriate distribution of chemotherapeutic drugs to all pediatric and adults cancer patients within the public health system, and upon the chilean hematology society for the development of a consensus on diagnosis, treatment and prevention of infections during fn episodes in cancer patients. the need for this consensus is based on two main aspects: the new approaches proposed during the past year for management of these episodes, and the increasing population of cancer patients receiving improved chemotherapeutic agents that has increased there survival possibilities as well as there possibility to suffer a fn episode. the topics discussed in this document are based on an updated systematic and analytic review of the medical literature including epidemiology, laboratory diagnostics, risk categorization, treatment and prophylaxis. national data was included when available in order to provide the healthcare personnel th

Revista Chilena de Enfermedades Respiratorias , 2007,
Abstract: Introducción: El tumor fibroso solitario de la pleura (TFSP) es una neoplasia infrecuente, considerada benigna, de crecimiento lento y poco sintomática pero que puede recidivar tras la resección quirúrgica. El objetivo de este estudio es mostrar la experiencia de nuestro centro con el manejo de estos tumores. Pacientes y Método: Análisis retrospectivo de 41 pacientes con TFSP intervenidos en nuestro Servicio entre 1991 y 2004. Se analizan datos clínicos, radiológicos, quirúrgicos, morbimortalidad, recurrencia y seguimiento. Resultados: De los 41 pacientes con TFSP resecados, 27 eran mujeres y 14 hombres. Edad media 60,4 a os. 24,4% de los pacientes fueron asintomáticos. Todos los pacientes fueron intervenidos quirúrgicamente y se realizó estudio histopatológico en todas las piezas. El peso promedio de los tumores fue de 954 g y 36,5% eran tumores pediculados, el resto de base ancha. La mayoría (75,6%) se originaban de la pleura visceral. No hubo mortalidad operatoria y la morbilidad alcanzó el 12,1%. Tres tumores recidivaron. Conclusiones: El TFSP es una neoplasia rara generalmente benigna, pero que puede recidivar. El tratamiento es la resección quirúrgica completa y las recidivas deben ser resecadas nuevamente Solitary fibrous tumor of the pleura (TFSP) is an uncommon and mostly benign neoplasm. It grows slowly and presents with scant symptoms. Recurrence after surgical excision has been described. The aim of this report is to show our experience in managing this disease. Clinical as well as radiological, surgical, histopathological and follow-up data were analyzed in a clinical series. Forty one cases of TFSP that underwent surgery at our institution between 1991 and 2004 were retrospectively analyzed; 27 were females and 14 males with a median age of 60.4 years old; 24.4% of the cases were asymptomatic. All tumors were surgically excised, in average they weighed 945 g and 36.5% of the lesions showed a pedicle. Most of the lesions were originated in the visceral pleura. Surgical morbidity was 12.1% and no mortality was recorded. Three tumor recurred. TFSP is usually a benign neoplasm but it can recur. Complete surgical excision is the treatment of choice of primary and recurrent tumors
Tratamiento quirúrgico de fístula arteriovenosa pulmonar en telangectasia hemorrágica hereditaria (Enfermedad de Rendu Osler Weber) Pulmonary arteriovenous fistula in hereditary hemorrhagic telangiectasia. Report of one case
Revista Chilena de Cirugía , 2010,
Abstract: Las Fístulas Arteriovenosas Pulmonares (FAVP son malformaciones vasculares infrecuentes. La Telangectasia Hemorrágica Hereditaria o Enfermedad de Rendu-Osler-Weber (EROW) es una enfermedad hereditaria autosómica dominante que se asocia con frecuencia a dichas malformaciones vasculares pulmonares. Presentamos el caso de una mujer de 16 a os con EROW y una FAVP única, sintomática y que comprometía extensamente el lóbulo medio, en quien realizamos tratamiento con cirugía resectiva pulmonar (lobectomía media) y que evolucionó satisfactoriamente con desaparición de la sintomatología. Hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) is an autosomal dominant vascular disease that can be associated with pulmonary arteriovenous fistulas. We report a 16 years old female with an Osler-Weber-Rendu syndrome and a history of frequent episodes of epistaxis since the age of 10 years. A Chest CAT sean performed on that occasion showed an arteriovenous fistula. The patient presented with progressive dyspnea, low arterial oxygen saturation and clubbing of fingers. An echocardiogram and lung perfusion scintigram confirmed the presence a right to left shunt. The patient was subjected to a lobectomy with a good postoperative evolution.

Abstract: Objetivos: Describir características, tratamiento y variables asociadas a supervivencia de neoplasias epiteliales del Timo (NET). Material y Método: Revisión retrospectiva de pacientes con NET. Período: enero de 2000 - agosto de 2010. Se describen características, tratamiento, morbilidad, mortalidad y supervivencia global. Se comparó supervivencias según variables seleccionadas. Se utilizó programa SPSS 15.0. Se consideró significativo p < 0,05. Resultados: 54 pacientes, 33 mujeres, edad promedio 52,5 a os. Sintomáticos 42 pacientes. Se realizó cirugía resectiva en 47. Histología: 46 Timomas y 8 Carcinomas Tímicos. Complicaciones en 14 y 1 falleció. Rango seguimiento: 12-156 meses. Tiempo promedio supervivencia 101,8 ± 10,2 meses. Supervivencia global a 1, 3 y 5 a os: 90,7 ± 3,9%, 81,4 ± 5,7% y 71,8 ± 8,2% respectivamente. Se encontraron variables asociadas a supervivencia. Conclusiones: Las NET son más frecuentes en mujeres, la mayoría son sintomáticos e histológicamente son timoma. La cirugía es resectiva en la mayoría. Se identifican variables asociadas a supervivencia. Background: Thymic epithelial tumors are uncommon and can be associated with myasthenia gravis. Aim: To describe variables associated with survival and treatment of thymic epithelial tumors. Material and Methods: Retrospective review of surgical databases of a respiratory diseases hospital, identifying patients operated for a thymic epithelial tumor between 2000 and 2010. Follow up lasted from 12 to 156 months and information was obtained from medical records and death certificates of the Chilean national identification service. Results: Data from 54 patients aged 52.5 ± 16.4 years (33 women) was retrieved. Forty two patients were symptomatic and 47 were subjected to resective surgery. The pathological diagnosis was thymoma in 46 cases and thymic carcinoma in eight. Fourteen patients had postoperative complications and one died. Mean survival time was 101.8 ± 10.2 months. One, three and five years survival was 90.7 ± 3.9, 81.4 ± 5.7 and 71.8 ± 8.2%, respectively. Preoperative performance status of patients, histological type of the tumor and associated myasthenia gravis were predictors of survival. Conclusions: More commonly, thymic epithelial tumors appear in women, their histological type corresponds to thymomas and their resection is feasible.

Abstract: El manejo de los pacientes pediátricos con cáncer y neutropenia febril (NF) requiere de su clasificación en alto o bajo riesgo de adquirir infecciones bacterianas invasoras (IBI), con el fin de implementar estrategias selectivas de tratamiento. Basados en nuestra experiencia y publicaciones internacionales al respecto, proponemos recomendaciones para el diagnóstico y manejo de ni os con cáncer y NF, categorizadas según riesgo de IBI. Todos los pacientes pediátricos que presenten episodios de NF deben ser ingresados al hospital por al menos 24 horas. Durante este lapso se efectuará su evaluación clínica y de laboratorio con el objeto de clasificar el riesgo de este episodio y precisar el (los) posible(s) foco(s). Los pacientes de alto riesgo deben continuar internados hasta su recuperación. Los de bajo riesgo pueden ser manejados en forma ambulatoria. La elección de la terapia antimicrobiana inicial y los criterios para su ajuste deberán basarse en el hallazgo o no de focos infecciosos y en los patrones epidemiológicos e institucionales de susceptibilidad. La reevaluación de ambos grupos debe ser periódica (al menos en los días 3, 5 y 7 de evolución), y la respuesta terapéutica será clasificada como favorable o desfavorable según criterios clínicos y parámetros de laboratorio preestablecidos Management of pediatric patients with cancer and febrile neutropenia (FN) requires appropriate identification of children at high or low risk of acquiring invasive bacterial infections (IBI), in order to implement selective treatment strategies. Based on international and our own research experience, we propose recommendations for diagnostic screening and management of children with cancer and FN according to their risk of IBI. All pediatric patients with FN must be admitted to hospital for at least 24 hours. During this period clinical and laboratory evaluations are aimed to determine their risk of IBI and to identify potential infectious focii. High risk patients should be managed in the hospital until recovery. Low risk patients can be managed as outpatients. Antimicrobial selection and possible adjustments to therapy will depend on the identification of an infectious focus, and/or local epidemiology and susceptibility patterns. Patients will require periodic clinical and laboratory reevaluation (day 3, 5 and 7 of evolution or more frequently if clinically indicated) irrespective of their risk category; response to treatment can be defined as favorable or unfavorable based in preestablished clinical and laboratory criteria in order to monitor the success of select

Abstract: This article discusses the division of constitutional jurisdiction as it relates toa suitable foreign policy for the strengthening of the autonomous state. Italso treats the growing importance of the migratory phenomenon consistingof the state establishing specific foreigner and immigration rights. Thismeans that any decisions that imply entry into or expulsion from the nationalterritory and the autonomous communities are made in accordance withtheir own political frameworks, available funds, standards of rights and aresubject, even in the case of foreign immigrants, to sectorial jurisdiction. Thestatutes may be an instrument, at least in part, for regulating this new reality.The reforms analysed deserve to be judged separately, however some ofthem, in particular the Catalan and, especially, the Andalusian statutesshow a clear willingness to confront a problem that cannot be avoided, theinfluence of immigration on their responsibilities, and to approach these withacceptable solutions that are more than likely in keeping with the logic of adecentralised state. Nevertheless, it is vital that reform to immigration lawsand the delegation of responsibilities regarding residency accompany thesestatutory provisions. Furthermore, it is perfectly possible to opt for a generalisationof the current model in the two aforementioned statutes and thisis the most reasonable course of action to take.
