Los linfomas derivados del tejido linfoide asociado a las mucosas (MALT) son entidades poco frecuentes, de bajo grado de malignidad con escaso o nulo compromiso ganglionar y representan cerca del 80% de los linfomas primarios pulmonares. La aparición sincrónica con adenocarcinoma de pulmón es un hallazgo extremadamente infrecuente. Presentamos el caso de un hombre de 68 años, ex-tabaquista, en quien durante el seguimiento de un nódulo pulmonar se identificó un segundo nódulo y la biopsia quirúrgica confirmó el diagnóstico de ambas neoplasias. The lymphomas of mucosa-associated lymphoid tissue (MALT), are uncommon entities, of low grade of malignancy with very infrequent or no lymph node involvement. They represent about 80% of the primary pulmonary lymphomas. The synchronous appearance with lung adenocarcinoma is an extremely rare finding. We present the case of an ex-smoker 68-year-old man, in whom, in the follow-up of a pulmonary nodule, a second pulmonary nodule was found. The surgical biopsy confirmed the diagnosis of both neoplasms.

El mieloma múltiple es una enfermedad oncohematológica, que representa el 15% de las enfermedades hematológicas malignas. La edad media de aparición es entre los 65-70 años, siendo muy poco frecuente en pacientes jóvenes; 2% son menores de 40 años. Presentamos el caso de una mujer de 36 años con antecedente de tabaquismo de 20 paquetes año. Consultó por disnea asociada a signos de insuficiencia cardíaca derecha, anemia, proteinuria, elevación de reactantes de fase aguda y patrón sugestivo de restricción moderadamente grave en la espirometría y caída de la capacidad de difusión de monóxido de carbono (DLco). El ecocardiograma doppler evidenció dilatación de cavidades derechas y signos de hipertensión pulmonar que se confirmó con cateterismo cardiaco derecho. En busca de la etiología se arribó al diagnóstico de mieloma múltiple. Multiple myeloma is a hematologic disease, which accounts for 15% of hematologic malignancies. The average age of onset is between 65-70 years and is very rare in young patients, as 2% are under 40 years old. We present a case of 36-year-old women with history of 20 pack years (p/y) smoking, who complaints of dyspnea associated with signs of right cardiac overload, anemia, proteinuria, elevated acute phase reactants and spirometry pattern suggestive of moderately-severe restriction and severe drop in diffusing capacity for carbon monoxide (DLCO). Echocardiogram evidence dilated right heart cavities and signs of pulmonary hypertension which is confirmed by right heart catheterization. In search of the etiology we arrive to the diagnosis of multiple myeloma.

Introduction: Home mechanical ventilation (HMV) represents a standard of care for ventilatory pump failure. The standard of care could be a determinant of deficiencies in the quality control of the treatment. Materials and Methods: In order to monitor compliance during home mechanical ventilation and optimize its effectiveness, we proposed a program through a day hospital conducted by pulmonologists and respiratory physiotherapists. A descriptive study was designed basing on a systematic collection database. Participants were consecutive patients with noninvasive ventilation or invasive mechanical respiratory assistance treated in the Pulmonology Service between July 2014 and December 2016. Results: 94 patients were included: 52 men (55%), age 64.4 ± 15.9 years, where 50% were obese or overweight (body mass index of 28.6 ± 8.46 kg / m²). 80 patients (84%) received home mechanical ventilation: noninvasive in 77 cases and invasive in three cases (4%). 14 patients (14.8%) were admitted to evaluate the indication of home mechanical ventilation. The following noninvasive ventilation modes were used: Bilevel S/T, 59 (62.7%); average volume-assured pressure support ventilation (AVAPS), 4 (4.2%); continuous positive airway pressure (CPAP), 6 (6.4%); servo-ventilation, 1 (1%). Three patients received volumetric ventilation. Mean compliance was 8.1 hours. Four patients did not use the device. 42.5% of patients remained hypercapnic. The setting was changed in 37 patients (46.2%), ventilatory mode was set in 2 (2.5%) and ventilation was suspended in two (2.5%). Adjustments in individual patients were clinically significant. Conclusion: This program let us improve training and identify a high percentage of patients with ineffective home mechanical ventilation, allowing for adjustments in the modality of treatment.

Introducción: La ventilación mecánica domiciliaria representa un estándar de cuidados en la insuficiencia de la bomba ventilatoria. El modelo de atención podría ser determinante de deficiencias en el control de calidad de este tratamiento. Material y métodos: Con la finalidad de monitorear el cumplimiento de la ventilación mecánica domiciliaria y optimizar su eficacia, propusimos un programa mediante hospital de día conducido por médicos neumonólogos y kinesiólogos respiratorios. Se diseñó un estudio descriptivo sobre una base de datos de recolección sistemática. Participaron pacientes consecutivos con ventilación no invasiva o asistencia respiratoria mecánica invasiva asistidos en el Servicio de Neumonología entre julio de 2014 y diciembre de 2016. Resultados: Participaron 94 pacientes; 52 hombres (55%), edad 64.4 ± 15.9 años; el 50% presentaban obesidad o sobrepeso (índice de masa corporal 28.6 ± 8.46 kg/m²). Recibían ventilación mecánica domiciliaria 80 pacientes (84%); no invasiva en 77 casos e invasiva en tres (4%). Se admitieron para evaluar la indicación de ventilación mecánica domiciliaria 14 pacientes (14.8%). Los modos de ventilación no invasiva utilizados fueron; bilevel S/T: 59 (62.7%), presión de soporte con volumen promedio asegurado (AVAPS average volume-assured pressure support ventilation); 4 (4.2%), presión positiva continua en la vía aérea (CPAP (continuous positive airway pressure): 6 (6.4%), servo-ventilación: 1 (1%). Tres pacientes recibían ventilación volumétrica. La media de cumplimiento fue de 8.1 horas. Cuatro pacientes no utilizaban el dispositivo. Permanecieron hipercápnicos el 42.5%. Se cambió la programación en 37 pacientes (46.2%), modo ventilatorio en 2 (2.5%) y se suspendió la ventilación en dos (2.5%). En pacientes individuales los ajustes fueron clínicamente significativos. Conclusión: El programa permitió mejorar el entrenamiento e identificar un alto porcentaje de ventilación mecánica domiciliaria ineficaz, permitiendo ajustes en la modalidad de tratamiento. Introduction: Home mechanical ventilation (HMV) represents a standard of care for chronic ventilatory pump failure. The care model could be determinant in deficiencies in the control of quality of HMV. Material and methods: In order to monitoring compliance during home mechanical ventilation and optimize its effectiveness, we proposed a program through a day hospital conducted by pulmonology doctors and respiratory physiotherapist. A descriptive study was designed on a systematic collection database. Participants were consecutive patients with NIV or mechanical invasive ventilation (MIV) assisted in the Pulmonology Service between July 2014 and December 2016. Results: During 30 months we included 94 patients; 52 men (55%), age 64.4 ± 15.9 years and BMI of 28.6 ± 8.46 kg / m². Fifty percent were obese or overweight. 80 were found with HMV (84%) noninvasive (NIV) in 77 cases and invasive in three (4%). 15 patients (16%) were admitted to evaluate indication of VMD. The NIV modes used were; Bilevel S / T: 59 (62.7%), AVAPS; 4 (4.2%), CPAP: 6 (6.4%), servo-ventilation: 1 (1%). Three patients received volumetric ventilation. The mean compliance objectively measured was 8.1 hours. Four patients did not use the device. Remained with hypercapnia 42.5%. The setting was changed in 37 patients (46.2%), ventilatory mode in 2 (2.5%) and HMV was suspended in two (2.5%). In individual patients adjustments were clinically significant. Conclusion: This program allowed to improve the training and to identify a high percentage of patients with ineffective HMV, allowing adjustments in the modality of treatment.

Maximum androgen blockade is the standard endocrine treatment for advanced prostate cancer. Interstitial lung disease in different degrees of severity, with low mortality and excellent response to treatment may appear with its use. We report a 77 years old patient with advanced prostate cancer who developed severe and progressive respiratory failure associated to bilateral pulmonary infiltrates, attributed to the direct effect of maximum androgen blockade. Despite the therapeutic efforts, the patient died. Lung pathology revealed Usual Interstitial Pneumonia.
