The so-called focal infections are today considered to be poly-etiologic manifestations, in which there is a summation of various aggressions. The concept of focal infection is still not exactly defined. Bacterial products, toxic or antigenic substances originating from different foci are but one of the elements susceptible of unleashing the disease. This explains why there are so many foci and so few results after their elimination. The diagnosis of chronic tonsillitis or occult sinusitis especially concerning a focal disease is sometimes difficult. The ENT-specialist is responsible for both the detection of a focus in the head and neck region and its operative treatment. The interrelationship between a focal infection and its actual secondary disease must be diagnosed by the primarily inquired doctor. The diagnosis and the treatment of focal infections of the head and neck region are an interdisciplinary problem.

"Medical" thoracoscopy as compared with "surgical" thoracoscopy (which is more precisely known as video-assisted thoracic surgery (VATS)) has the advantage that it can be performed under local anaesthesia or conscious sedation, in an endoscopy suite, using nondisposible rigid instruments. Thus, it is considerably less invasive and less expensive. The main diagnostic and therapeutic indications for medical thoracoscopy are pleural effusions and pneumothorax. Due to its high diagnostic accuracy, approaching almost 100% in malignant and tuberculous pleural effusions, it should be used when pleural fluid analysis and needle biopsy are nondiagnostic. In addition, medical thoracoscopy provides staging for lung cancer and diffuse malignant mesothelioma. Talc poudrage, as the best conservative method for pleurodesis in 1998, can also be performed with medical thoracoscopy. It can also be effectively used in the early management of empyema. In spontaneous pneumothorax it allows staging, thereby facilitating treatment decisions, and in addition coagulation of eventual blebs and talc poudrage for efficient pleurodesis. Medical thoracoscopy is a safe procedure which is even easier to learn than flexible bronchoscopy. Due to its high diagnostic and therapeutic efficiency, it should be applied increasingly in the management of the above-mentioned pleuropulmonary diseases.
