Collaborative registry of pulmonary hypertension in Argentina (RECOPILAR). Final analysis.

The epidemiology of pulmonary hypertension (PH), especially pulmonary arterial hypertension (PAH), has not been evaluated in our country, therefore there is no reference parameter to establishing the representativeness of this information in the national order. This registry represents the first collaborative effort to provide a knowledge base of this disease, including 5 scientific societies that represent different specialties (pediatrics, rheumatology, pulmonology and cardiology) with data from 23 Argentine provinces. These efforts involved five societies of various adult (cardiology, rheumatology, and pulmonology) and pediatric (cardiology) specialties.

[Pharmacological and mechanical thrombolysis in submassive pulmonary embolism].

Thromboembolic pulmonary disease is challenging for physicians when diagnosed in acute, sub-acute and chronic clinical patients, not only due to its morbi-mortality, but also because of its complex therapeutic management. Severity of the acute condition and potential commitment of right ventricular systolic function require therapeutic strategies, sometimes combined, in order to change the disease's course, optimizing patient survival. Pharmacological and mechanical thrombolysis are useful therapeutic tools for patients suffering from severe acute pulmonary embolism.

[Treatment of compression of the left main coronary artery in patients with pulmonary hypertension].

Chest pain is a frequent symptom in patients with pulmonary hypertension of any etiology. Its pathophysiology has not been clearly established, the proposed causes are ischemia due to increased right ventricle wall stress, transient increased pulmonary hypertension resulting in acute pulmonary artery dilatation and external compression of the left main coronary artery (LMCA) by a dilated pulmonary artery. We report and discuss here three cases where the association between chest pain and compression of the LMCA by a dilated pulmonary artery could be shown, and they were treated with coronary stenting.

[Update in the diagnosis and treatment of pulmonary hypertension].

The term pulmonary hypertension includes a heterogeneous group of disorders which produce an obstructive remodeling of the lung vessels characterized by a steady rise in pulmonary arterial pressure. The ensuing morbidity and mortality of this disease result from the failure of the right ventricle to compensate this increase in the after-load. The conditions to achieve an optimum treatment of pulmonary hypertension patients are: a clinical presumption and early diagnosis, an adequate stratification based on the underlying causes and the different vascular territories involved, the response to therapy and the degree of severity, the selection of the different therapeutic alternatives and their timely indication.

Open lung biopsy for diffuse disease in patients with and without previously transplanted solid organs.

Background: Studies on whether surgical lung biopsy (SLB) modifies the treatment of patients with diffuse lung disease are conflicting, and information is limited on whether it alters treatment in solid-organ transplant recipients. Our objective was to determine and compare the rate of treatment change after SLB for diffuse lung disease in patients with and without a history of solid-organ transplantation.

Methods: Patients undergoing SLB for diffuse lung disease between March 2004 and March 2009 were identified.

[Editorial situation of seven Latin American journals on respiratory diseases].

A survey was conducted in a meeting sponsored by ALAT (Latin American Association of Thoracic Diseases). Each of the seven editors reported about their journal and answered a questionnaire. The improvement in knowledge divulgation is the main motivation of respiratory societies to edit their own journals.

Situational study of seven Latin-American pulmonology journals.

Objective: To characterize the situation of pulmonology journals published in Latin America.

Methods: A survey was conducted in a meeting sponsored by the Latin American Thoracic Society. Each journal editor presented a report and answered a questionnaire.
