          Abstract

          Neste estudo é relatado o caso de um paciente do sexo masculino, 14 anos de idade, que após fazer grande esforço vocal, durante uma partida de futebol, desenvolveu quadro agudo de dor torácica. As radiografias de tórax e a tomografia computadorizada evidenciaram pneumomediastino, com pequeno pneumotórax bilateral. Os exames clínico, laboratoriais e radiológicos não demonstraram qualquer fator predisponente, ficando o caso classificado como pneumomediastino espontâneo.

          Translated abstract

          The present article reports the case of a 14-year-old male patient who developed acute chest pain following increased vocal effort during a soccer game. Chest radiography and computed tomography demonstrated pneudomediastinum with small bilateral pneumothorax. Clinical, laboratory and radiological studies did not demonstrate any predisposing factor, and the case was classified as spontaneous pneudomediastinum.

          Thirty years of surgery for carcinoma of the bronchus.

          J. Belcher (1983)
          A study has been made of 8781 patients with bronchial carcinoma who were operated on by seven surgeons in England during the years 1949-80. There were 3865 pneumonectomies, 3790 lobectomies, and 1126 thoracotomies. During this period the operative mortality has fallen. Neither the resection rate nor the proportion of lobectomies bears any relation to the survival rate in any series. There has been remarkable similarity between the various survival rates in that the difference at five years was only 1.3% (25.5-26.8%) and at 10 years 4.2% (13.6-17.8%). These figures are reflected in reports published worldwide, where there is also great similarity between the results. If the improvement in operative mortality is excluded, there has been no improvement in the survival rates in the last thirty years.

            Idiopathic spontaneous pneumomediastinum: an uncommon emergency in children.

            Spontaneous pneumomediastinum (SPM) occurs rarely in children. The diagnosis is based on physical examination and chest radiography. Conservative therapy usually leads to recovery. However, SPM in association with severe hypoxia, tachycardia, metabolic acidosis, and high ventilation pressures indicates clinically significant tension in the mediastinum. A collar mediastinotomy is the treatment of choice in these circumstances.
