[Diagnosis and therapy of pleural empyema].

21 patients with thoracic empyema were treated at this clinic over a period of 3 years. 15 patients had metapneumonic empyema, 2 empyema associated with sepsis, and 4 postsurgical empyema. In 12 patients the underlying illness was chronic disease while 9 patients were thus far in good health. The most frequent causative pathogens were staphylococci and streptococci, together with anaerobic bacteria. One patient died of the underlying disease. Three cases of metapneumonic empyema healed completely with antibiotics only. Closed chest tube drainage with small chest tube was performed 13 times and was successful 11 times with a mean drainage duration of 13 days. Six patients underwent surgery (early decortication in 4 instances, late decortication in 2). The surgical indication was in 4 instances multilocular of the empyema which inhibited chest tube drainage, imminent loss of function in 1 case and unsuccessful drainage in a case of bronchopleural fistula in 1 instance. Apart from high-dose antibiotic therapy, earliest possible drainage is of crucial importance in the treatment of thoracic empyema. Surgery should be considered only in uncomplicated empyema if drainage is impossible for technical reasons.

[The significance of computerized tomography of the chest in the staging of bronchial carcinoma].

The value of thoracic computed tomography in the staging of non-small cell bronchogenic carcinoma is evaluated. In 57 patients post thoracotomy and in 8 patients who had undergone mediastinoscopy, the preoperative T and N stages determined by CT were compared with the intraoperative stage. With respect to the T3 stage, 49 CT results out of a total of 57 were correct, 6 were false positive and 2 false negative. This corresponds to a sensitivity of 67% and a specificity of 88%. With respect to the N2 stage, 55 out of 65 results were correct, 8 were false positive and 2 false negative, corresponding to a sensitivity of 87% and a specificity of 84%. We conclude that in N2-negative CTs mediastinoscopy can be omitted, while in CT-positive patients histological verification appears to be necessary. The diagnosis of T3 should be carried out with caution: in doubtful cases surgical exploration is recommended.

Lasting improvement of renovascular hypertension by transluminal dilatation of atherosclerotic and nonatherosclerotic renal artery stenoses. A follow-up study.

Sixteen consecutive patients with renovascular hypertension were treated by transluminal dilatation and observed during 6 - 39 months (mean 21.8 months). Poststenotic renal artery pressure increased (p less than 0.001) and the renal arteries were patent on angiograms taken immediately after dilatation. In 13 patients, angiography was repeated 2 - 9 months later; at that time the selective renal vein renin ratio had decreased (p less than 0.001). At the end of the follow-up, blood pressure was improved or normal in 14 cases. One of the eight patients with atherosclerosis was normotensive without treatment, compared with five of six patients with fibromuscular dysplasia (p less than 0.05). The results in two cases with vasculitis are uncertain. The four patients with relapses, one after intimal catheter dissection, were treated successfully by redilatation. Thus, renovascular hypertension can be improved by transluminal dilatation in patients with atherosclerosis and in patients with fibromuscular dysplasia with lasting success and a low morbidity rate.

[New aspects in the treatment of renal artery stenosis].

Demonstration of new methods in the treatment of renal artery stenosis appears justified if one takes into account that the overall results of conventional surgical treatment are less than satisfactory. Reimplantation of the renal artery, renal auto-transplantation and transluminal dilatation are examples of new approaches. The early results of a series of transluminal dilatations are encouraging and are presented here for consideration.

[Kidney transplantation in the treatment of hypertension].

Renal autotransplantation seems to be of great value as a means of renal revascularization in hypertension of renovascular origin, especially in those cases in which the preceding angioplastic procedure have resulted in failure or in cases with peripheral or difficult stenoses of the renal artery. One case is reported with a coarctation of the abdominal aorta involving both kidney arteries. The patient was treated by bypass operation and kidney autotransplantation. Two years later both kidneys are functioning normally and the patient is normotensive.

Metastatic chordoma.

The authors present two cases of vertebral chordomas with widespread metastases. The literature is reviewed and the metastatic potential of chordomas is analysed.

[Dangers of thoracic drainage].

Three case histories are presented in order to demonstrate the hazards of apparently well-placed pleural chest tubes. In one instance of ruptured diaphragm the dislocated and distended stomach imitated a pneumothorax, thus inviting thoracic drainage; in two other cases the drainage of a massive hematothorax accelerated the oncome of hemorrhagic shock.

[Quality of life and the subjective well-being after successful kidney transplantations].

The quality of life following kidney transplantation is examined. For this reason a total of 38 patients were questioned. There were three subgroups: 18 adults and 10 children with excellent kidney function and 10 patients in whom nephrectomy had to be performed after rejection of the transplanted organ. The extent and importance of the changes of various criteria considered essential for judgement of the quality of life are illustrated. Adults and children alike consider the improvement of drinking and eating habits, improvement of physical fitness and of the capability to deal with psychological problems as the essence of their greater joy in life. For children there are added advantages at school and in the choice of their occupational activity. In conclusion there is a definite improvement of the quality of life following renal transplantation.

Hemodialysis and renal transplantation in childhood: description of a program.

Over a 2-yr period eight kidneys have been transplanted in seven patients at the University Children's Hospital of Berne. Six of these patients are alive 4-24 mo after transplantation. The results seem encouraging and the procedure justified, especially in view of the chance of full rehabilitation, which is obviously less complete with chronic hemodialysis.
