Pneumomediastinum,subcutaneous emphysema,and pneumothorax after a pulmonary function testing in a patient with bleomycin-induced interstitial pneumonitis

Spontaneous pneumomediastinum is an uncommon event, the clinical picture of which includes retrosternal chest pain, subcutaneous emphysema, dyspnea, and dysphonia. The pathophysiological mechanism involved is the emergence of a pressure gradient between the alveoli and surrounding structures, causing alveolar rupture with subsequent dissection of the peribronchovascular sheath and infiltration of the mediastinum and subcutaneous tissue with air. Known triggers include acute exacerbations of asthma and situations that require the Valsalva maneuver. We described and documented with HRCT scans the occurrence of pneumomediastinum after a patient with bleomycin-induced interstitial lung disease underwent pulmonary function testing. Although uncommon, the association between pulmonary function testing and air leak syndromes has been increasingly reported in the literature, and lung diseases, such as interstitial lung diseases, include structural changes that facilitate the occurrence of this complication.     

Chirurgische Therapie des malignen Pleuramesothelioms

Malignant pleural mesothelioma (MPM) is a rare and aggressive tumor disease, which rapidly leads to death if untreated. In Germany the incidence of newly occurring disease is expected to reach a peak in the coming 5 years. An R0 resection for MPM is technically impossible; therefore, the aim of surgical procedures is to achieve the maximum amount of cytoreduction. There are two established surgical techniques for treatment of MPM, extrapleural pneumonectomy and tumor pleurectomy with decortication. The type and extent of surgery are currently controversially discussed. Within multimodal therapy concepts including cytoreductive surgery, long-term remission is possible in selected patients. When choosing the appropriate surgical therapy the high incidence of recurrence has to be borne in mind.
