[The epidemiology of asthma in adults. An insight].

Background: Asthma is a chronic disease with a great impact on public health and on the patients' quality of life. In Latin America, there are scarce epidemiological studies.

Objective: To describe the prevalence of asthma and the clinical-demographic characteristics in an adult population from a private health system in the City of Buenos Aires.

Cryoprobe biopsy for the diagnosis of acute hypoxemic respiratory failure of undetermined origin.

Rationale: Acute hypoxemic respiratory failure is a condition that comprises a wide array of entities. Obtaining a histological lung sample might help reach a diagnosis and direct an appropriate treatment in a select group of patients.

Objective: To describe our experience in the use of cryobiopsy for the diagnosis of acute hypoxemic respiratory failure of undetermined origin.

[Therapeutic bilateral lung lavage in an adolescent with pulmonary alveolar proteinosis. Case report].

Pulmonary alveolar proteinosis is an unusual diffuse lung disease characterized by abnormal accumulation of pulmonary surfactant and lipoproteins in the alveolar space, which impairs gas exchange with a variable clinical course, ranging from an asymptomatic clinical presentation to severely affected respiratory failure. A 16-year-old girl with diagnosis of pulmonary alveolar proteinosis presented to our hospital for therapeutic lung lavage after a recent history of progressive dyspnea, respiratory distress, declining lung function measurements, and worsening radiographic abnormalities. We obtained baseline pulmonary function tests and laboratory measurements before and after therapeutic bilateral lung lavage.

[Bilateral single sesion whole lung lavage under venous-venous ECMO in a case of severe pulmonary alveolar proteinosis: five years follow up].

Unlabelled: Introduction: Pulmonary alveolar proteinosis (PAP) is a rare disease caused by accumulation of proteinaceous material in the alveolar spaces. The most common mechanism implied is the development of antibodies directed to granulocyte macrophage colony stimulating factor (GM-CSF). which inhibits activation of alveolar macrophage, thereby causing accumulation of surfactant.

Lung transplantation in a patient with arteriovenous malformations.

Multiple arteriovenous fistulas (AVF) is an infrequent pathology, in which lung transplant is controversial. We report a patient with hereditary hemorrhagic telangiectasia who underwent a single lung transplant with excellent evolution, and three years later (that is, at the time of this paper), she is still alive.
