Experience with the Nuss technique for the treatment of Pectus Excavatum in Spanish Thoracic Surgery Departments.

Introduction: Although the Nuss technique revolutionized the surgical treatment of pectus excavatum, its use has not become widespread in our country. The aim of this study was to analyze the current use of this technique in a sample of Thoracic Surgery Departments in Spain.

Methods: Observational rectrospective multicentric study analyzing the main epidemiological aspects and clinical results of ten years experience using the Nuss technique.

[Detection of lymph node involvement and surgical treatment of pulmonary neoplastic processes. Current state of diagnostic and therapeutic procedures].

An analysis is made of different publications associated with the surgical staging and treatment of primary and metastasic pulmonary neoplastic processes. A suitable treatment program is essential to determine lymph node involvement in patients with bronchogenic carcinoma. The indication and sequence of the procedure to use (CT-PET, transbronchial puncture, videomediastinoscopic ultrasound guided transbronchial needle aspiration) is evaluated in accordance to the sensitivity, specificity and positive and negative predictive value of the different methods.

[Interleukin-8 expression in lung tissue during ischemia-reperfusion].

Objective: Local cytokine production is a pathogenic factor in ischemia-reperfusion injury in early graft dysfunction. This study analyzed interleukin 8 (IL-8) messenger RNA (mRNA) expression in lung tissue and the association between IL-8 mRNA levels and interstitial lung changes in an experimental model of warm lung ischemia-reperfusion.

Material And Methods: We studied 16 New Zealand rabbits divided into 3 groups: control, ischemia (tissue taken from right lower lobe after 1, 2, or 3 hours of ischemia), and reperfusion (tissue taken from right upper and middle lobes after 1 hour of ischemia and 1, 2, or 3 hours of reperfusion).
