[Bilateral pneumothorax complicating cavitary pulmonary metastases in angiosarcoma]. / Neumotórax bilateral como complicación de metástasis pulmonar cavitaria de un angiosarcoma.

Metastatic pulmonary angiosarcomas are a common complication of a rare condition. Generally, they are presented as peripheral solid nodules, infiltrates, and pleural effusions. We report the case of a 65 year-old man with bilateral recurrent pneumothorax secondary to metastatic cavitary lesions from angiosarcoma of the scalp. In this case, videothoracoscopy allowed tumor resection, inspection, and pleurodesis. There weren't complications or tumor recurrence at six months follow up.

Las metástasis pulmonares de angiosarcoma constituyen una complicación común de una neoplasia maligna poco frecuente. Habitualmente se presentan como nódulos solidos periféricos y derrame pleural. Presentamos el caso de un hombre de 65 años de edad con neumotórax bilateral recurrente, secundario a metástasis cavitadas de un angiosarcoma primitivo de cuero cabelludo. La videotoracoscopia permitió la inspección, la resección de las metástasis y la pleurodesis. No ocurrieron complicaciones ni recurrencia tumoral a los seis meses de seguimiento.

[Mechanical ventilation. Influence of the age in the outcome]. / Asistencia respiratoria mecánica. Influencia de la edad en la evolución.

There is not consensus about the true influence of age on mortality associated to mechanical ventilation (MV). We performed a prospective study in order to determine if age is an independent factor to predict mortality in patients under MV. Two hundred patients requiring MV at the intensive care unit were included and clinical variables at admission, co-morbidities, complications and outcome at the hospital and after 6 months were registered. Patients were divided in 2 groups: Group 1 (n = 164) under 80 year old and Group 2 (n = 36) 80 year or older. There were no differences in intensive care unit or hospital mortality between the two groups (55.56% vs. 41.46% and 58.33% vs. 42.68%). Six-month survival were significantly lower in patients over 80 year-old (22.22% vs. 48.17%, p = 0.0051). Multivariate analysis showed that only an APACHE II score > 20 (p = 0.0077) or the absence of an autonomous life (p = 0.0028) were independent predictive factors of mortality. Elderly patients under mechanical ventilation do not show a higher mortality because of the advance age in itself. Restriction of mechanical ventilation and invasive care does not seem to be justified based on the advanced age.

Asistencia respiratoria mecánica: Influencia de la edad en la evolución / Mechanical ventilation: Influence of the age in the outcome

No existe un concepto definido sobre la influencia de la edad en la mortalidad de la asistencia respiratoria mecánica. Realizamos un trabajo prospectivo-observacional para determinar si la edad es un factor independiente de mortalidad de la asistencia respiratoria mecánica. Se incluyeron 200 pacientes internados en la Unidad de Cuidados Intensivos del Hospital Británico de Buenos Aires. Se registraron características y comorbilidades al ingreso, al inicio de la asistencia respiratoria mecánica, complicaciones y evolución en el Hospital y a los 6 meses. Los 200 pacientes incluidos fueron divididos en dos grupos: Grupo 1 (n = 164) menores de 80 años y Grupo 2 (n = 36) de 80 años o más. No hubo diferencias en la mortalidad en la Unidad de Cuidados Intensivos y en el Hospital entre los pacientes menores de 80 años y los de 80 años o más. (55.56% vs. 41.46% y 58.33% vs. 42.68%). La supervivencia a los 6 meses de los = 80 años fue significativamente menor (22.22% vs. 48.17%, p = 0.0051). En el análisis multivariado solamente un APACHE II > 20 (p = 0.0007) o la ausencia de vida autónoma (p = 0.0028) conservaron poder predictivo independiente. Los pacientes añosos que reciben asistencia respiratoria mecánica no presentan una mayor mortalidad por el sólo hecho de ser ancianos. La restricción de los cuidados terapéuticos invasivos no parece justificada por la edad avanzada.

Embolismo pulmonar tumoral: Reporte de dos casos / Pulmonary tumor embolism: Report of two cases

Dyspnea and hypoxemia in a patient with cancer may have several causes, including infections, thromboembolism, metastases, and pulmonary injuries by drugs. We report a 47-year-old female with breast cancer and a 70-year-old male with urinary bladder cancer who were admitted for dyspnea, hypoxemia and pulmonary hypertension. Chest X rays and CT scans were normal. The ventilation-perfusion scintigram was highly suspicions of thromboembolism in the female. The male died 16 hours after admission and the post mortem examination revealed the presence of tumor cells in the pulmonary vasculature.

Fracturas costales múltiples asociadas a tos

La tos es un frecuente motivo de consulta en la práctica ambulatoria. Aunque generalmente es autolimitada, cuando es crónica e intensa puede ser causa de complicaciones como síncope, neumotórax o más raramente fracturas costales. Presentamos un paciente con fracturas costales múltiples inducidas por la tos. El diagnóstico fue confirmado por un centellograma solicitado luego de la sospecha clínica debida a la intensidad y persistencia del dolor y a pesar de no mostrar alteraciones en las radiografías convencionales. Un centellograma de control a los 5 meses mostró desaparición de los focos hipercaptantes. Las fracturas costales múltiples son una complicación infrecuente de la tos que debería considerarse cuando el dolor torácico es intenso y persistente aun con radiografía de tórax o parrilla costal normal.

Multiple rib fractures associated with cough.

Cough is a common symptom in ambulatory practice and in general does not require specific treatment. When the cough is chronic it can provoke complications such as syncope, neumothorax or, rarely, rib fractures. We report a case of a patient with multiple rib fractures caused by cough. The diagnosis was performed by scintigraphy but fractures were not found in the x-rays. Five months later, a scintigraphy showed disappearance of the increased uptake areas. Multiple rib fractures are a cough complication which should be considered when the patient’s pain is persistent even if there is no x-ray evidence.

Absceso intramedular en paciente con enfermedad de Rendu-Osler-Weber / Spinal abscess in a patient with hereditary hemorrhagic telangiectasia

La enfermedad de Rendu-Osler-Weber es una enfermedad autosómica dominante que se manifiesta por telangiectasias en piel y mucosas y malformaciones arteriovenosas en diversos órganos. El compromiso neurológico puede ocurrir por la presencia de malformaciones arterio-venosas cerebrales, hemorragia intracraneal, y más habitualmente por accidentes cerebrovasculares isquémicos y abscesos cerebrales secundarios a embolia paradojal, en pacientes con malformaciones arteriovenosas pulmonares. El absceso intramedular es una entidad rara, inusual como complicación de la enfermedad de Rendu-Osler-Weber. Presentamos el caso de una mujer de 56 años de edad, con antecedentes familiares de enfermedad de Rendu-Osler- Weber, que ingresó a Terapia Intensiva con cuadriplejia aguda e hipoxemia, en quien se diagnosticó fístulas arteriovenosas pulmonares y un absceso intramedular cervical.

Rendu-Osler-Weber syndrome is an autosomal dominant disorder characterized by multiple skin and mucosal telangiectasis and multiorgan arteriovenous malformations. Neurological manifestations may occur because of cerebral arteriovenous malformations, intracranial hemorrhage, and most commonly by ischemic stroke and brain abscess secondary to paradoxical embolization in patients with pulmonary arteriovenous malformations. Intramedullary abscess is a rare, unusual condition, in Rendu-Osler-Weber syndrome. We report the case of a 56 years old woman, with a familial history of Rendu-Osler-Weber syndrome, admitted to intensive care with acute quadriplegia and hypoxemia. Our diagnosis was pulmonary arteriovenous malformations and intramedullary abscess.

[Impending paradoxical embolism]. / Embolia paradojal inminente.

Impending paradoxical embolism. An intracardiac thrombus traversing a patent foramen ovale is a very infrequent but potentially catastrophic complication of the thromboembolic disease. It is named "impending paradoxical embolism". We report the case of a 71-year-old Caucasian male warded in ten days after a prostatectomy because of bilateral pulmonary embolism. Diagnosis was confirmed by HCT scan and the patient received anticoagulation with heparin. A transesophageal ecocardiogram disclosed a thrombus traversing foramen ovale into the left atrium. Surgical embolectomy was performed, but the patient died shortly after surgery.

Embolia paradojal inminente / Impending paradoxical embolism

La presencia de un trombo venoso atrapado en un defecto interauricular e insinuándose en las cavidades izquierdas configura una forma extremadamente inusual de enfermedad tromboembólica denominada embolia paradojal inminente. Presentamos el caso de un varón de 71 años, sometido 10 días antes a adenomectomía prostática, que consultó por disnea y mareos. Se le diagnosticó tromboembolismo pulmonar bilateral por tomografía axial computada helicoidal. Se lo anticoaguló con heparina sódica y se le realizó un ecocardiograma transesofágico que mostró un trombo que atravesaba el foramen oval y se alojaba en la aurícula izquierda. No presentaba signos clínicos de embolización sistémica. Se realizó la embolectomía quirúrgica y cierre del defecto auricular. El paciente falleció

Hemoptisis masiva por fístula aorto bronquial / Massive hemoptysis from an aortobronchial fistula

This is a report of a 61 year old man who was admitted at the Intensive Care Unit because of massive hemoptysis and respiratory failure. Four years before he had had an aortic dissection type A, and at that time an aortic valve, ascending aorta and aortic arch replacement, had been carried out. A thorax CT scan showed an aneurysm of the ascending aorta. A bronchoscopy was normal. In the angiography, a collateral of the left mammary artery was identified as the cause of bleeding and was subsequently embolized. After the procedure, the patient had a new episode of massive hemoptysis, and surgery was recommended. During surgery, the diagnosis of aortobronchial fistula was confirmed but the patient died during the intervention.

Insuficiencia respiratoria aguda por neumonia lipoidea / Acute respiratory failure due to lipoid pneumonia

Se presenta un paciente de sexo masculino e3 63 años de edad que ingresó por un síndrome febril, tos, expectoración e insuficiencia respiratoria severa. El lavado broncoalveolar reveló una baciloscopia positiva por lo que indicó un tratamiento especifico con cuatro drogas antituberculosas. Ante la ausencia de mejoría el paciente requirió asistencia respiratoria mecánica. Una tomografía computada de tórax mostró signos compatibles con neomonía lipoidea tales como el compromiso de zonas declives del pulmón, hipodensidad de las mismas y el signo del angiograma. Un nuevo interrogatorio familiar constató ingesta crónica de vaselina por constipación. Se decidió tratamiento con altas dosis de esteroides y lavado pulmonar total, que permitió el retiro de la asistencia respiratoria mecánica. Se comenta la asociación de esta patología con infecciones por micobacterias atípicas.
