[Spirometric course control after lung surgery].

72 patients who had undergone pulmonary resection for different causes and of varying degree were followed up by spirometry over a period of two years at 6-month intervals. The patients were allocated to groups according to the preexistent bronchiolar obstruction and extent of lung resection. FEV1 was found not to be essentially altered by surgery. The adaptation of lung function takes at least one year. Ventilatory reserves remain sufficient. The measured spirometric values in pneumonectomized patients two years after operation are 10% above predicted values.

The post-natal development of lymph nodes in mice.

A total of ten major lymph node stations have been studied in ICR-strain mice at various time intervals between birth and the age of four weeks. Comparison of lymph node volumes and of volume changes during the observation period revealed that the mesenteric lymph node (MLN) complex was larger at birth and grew at a faster rate than all other nodes. A distinct numerical increase of cortical lymphocytes in MLN at the end of the first week of life was interpreted to be the result of both immigration of T cells and moderate local proliferation, while the quantitatively more important second phase of growth at the age of between two and three weeks might be the consequence of local lymphocyte production. The comparatively modest changes in lymph nodes removed from the gut (axillary and popliteal nodes) could be explained as being due in large measure to immigration of lymphocytes originating in gut-associated lymphoid tissues (GALT).

[Thorascopy as a diagnostic and therapeutic precaution in lung and pleural diseases].

Thoracoscopy is a method involving little discomfort for the patient but of high diagnostic effectiveness for pleural alterations. A histological diagnosis was established in 56 cases out of a total of 60 pleural effusions of unknown origin. In 10 pleural or pleuropulmonary diseases, anatomical classification was possible in all cases. In cases of pneumothorax (21 patients) the bronchopleural fistula could very often be seen and closure by detaching of pleural adhesions or cauterization was possible. These manipulations are usually followed by insufflation of sterile talcum powder through the thoracoscope. Suspicion of ruptured diaphragm due to accident was easily and quickly verified. No complications occurred in our 100 thoracoscopic examinations.

[Therapeutic recommendations in idiopathic spontaneous pneumothorax].

The treatment of spontaneous pneumothorax is still controversial. To evaluate pleural drainage with a chest tube the therapeutic results in 73 patients with benign pneumothorax were reviewed. Benign spontaneous pneumothorax treated with a thick chest tube size Charrière 18-22 disappeared within an average of only 6.6 days. On the other hand, the high recurrence rate of 24% after the initial pneumothorax and 37% after the first recurrence is comparable with the results of conservative management in other pneumothorax series in the literature. Small pneumothorax without severe symptoms should therefore be supervised conservatively on an outpatient basis. The more extended forms of pneumothorax should be treated with thick chest tubes. Failure of therapeutic effect, second ipsilateral relapse or the first contralateral pneumothorax are indications for parietal pleurectomy.
