[Evaluation of the degree of infundibuliform abnormality of the thorax and technics of the fixation of the sternum].

The author proposes an original method of determination of the degree of deformation in angular values on the basis of his experience in the treatment of 27 patients with infundibulum-like deformation of the chest. In case of surgical treatment the method of thoracoplasty after N. I. Kondrashin is preferable. The design formula of the size of the resected rib area is proposed. To stabilize the framework of the chest fixation by crossing wires on the ring support after G. A. Ilizarov is suggested. Submerged crossing wires with bent supporting ends were used for more continuous fixation.

[Bedside pictures and thorax-CT of intensive care patients].

Computed tomography is a rare radiologic procedure in the intensive-care patient. This is due to the complicated procedure involved. Although x-ray film imaging in the supine patient has definitely improved in quality, computed tomography will continue to be used as the decisive method in cases that cannot be clarified completely, i.e. complex lesions, drainage, in the first examination of a polytraumatic patient, in the search for empyemas and abscesses, and in the clarification and identification of mediastinal processes.

[Radiological examination of the thorax in intensive therapy centers].

Bedside chest radiography plays a considerable role in the whole of the exams carried out in hospitals, especially in intensive care units. Many clinical problems (pulmonary, cardiac, and mediastinal) are related to this examination and can be dealt with only when the radiologist is provided with high-quality radiographs. Therefore, it is extremely important for the radiologist himself to be aware of the various factors implied in the making and reproducing of bedside chest radiographs, which is a fundamental step in the monitoring of the patients undergoing intensive care. These factors can be divided into methodological factors (patient positioning, focus-film distance, and exposure) and technical factors (portable units, survey system). In this paper, a special emphasis is put on a survey system consisting in double differentiated screens and double film, which allows the acquisition of a normo-exposed radiograph of the parenchyma and of one of the mediastinum with a single exposure. Besides these technical and methodological elements, the radiologist must pay attention to the diagnostic-therapeutical means (such as tubes, small probes, and catheters) used on most patients in intensive care units. Their exact positioning must always be checked, and possible incorrect positioning and complications must be detected promptly. All these factors, as well as their scrupulous and constant application, contribute to markedly improve the dialogue between clinician and radiologist, by allowing a rapid evaluation of the cause of the clinical case under examination and its adequate treatment.

[The thorax of patients in diving accidents. Radiologic study].

On the basis of a series including 185 files on diving accidents gathered between 1981 and 1988, the authors carry out a radiological study of the thoracic signs observed after drowning and lung overpressure. The typical radiological form and the various clinical forms of drowning and lung overpressure are described in this article. Emergency plain thoracic radiography in bed in the method of choice. However, the existence of many false-negative findings leads to proposing a study with computed tomography (CT) after initial treatment in order to better assess the lesions and to characterize the accident. The utility of radiology is also demonstrated for the follow-up of evolution. Lastly, the authors lay stress on the necessity to prevent such accidents, to which radiologists can contribute by detecting thoracic lesions (dystrophy and other evolutive lesions) for which diving is contraindicated.

[Radiological study of the thorax. Evaluation of efficacy-efficiency of a large-field image intensifier in mass screening].

Chest X-ray is the most frequent examination in radiology and accounts for a considerable portion of total population radiation exposure, mostly in screening programs. The ideal radiographic system is the one providing the best image quality together with the lowest dose to the patient, at a low cost. In this paper the authors analyze the potentials of a new chest X-ray examination unit equipped with a large-screen image intensifier (TS 57-Siemens). Two-thousand subjects were examined with this unit. The technical aspects of everyday practice are analyzed from the radiologist's point of view, together with the dose to the patient, image quality, and costs.

[Alternating chemotherapy and radiotherapy in the induction treatment of small cell bronchial carcinoma (forms limited to the thorax)].

Sixty three patients with limited small cell lung carcinoma were entered into a pilot study alternating monthly cycles of combination chemotherapy (doxorubicin, VP16213, cyclophosphamide and methotrexate (group A) or cis platinum (group B) with 3 courses of mediastinal radiotherapy. The total mediastinal dose was 45 Gy for the first 28 patients (group A) and 55 Gy for the remaining 35 (group B). The complete response rate was 86% in group A (median survival 14 months) and 91% in group B (median survival 20 months). Local control at two years was 61% in group A and 82% in group B, while relapse-free 2 year survival rates were 32% and 37% respectively. The acceptable toxicity and high response rate of this combined modality therapy lead us to further research in maintenance therapy.

[Profitability of the radiological examination of the thorax. Development of thoracic radiology, administered dose, quality control and role of the clinic].

The considerable spreading of chest X-ray (about 50% of all radiological examinations--WHO official report No. 698), and its biological and economic high cost, make interesting the cost/benefit evaluation of this simple and world-wide X-ray examination. The evaluation, highly important although very complex, is concerned with many different problems. The different problems, such as the development of radiological diagnosis in pulmonary diseases, dose of exposure, quality assurance and clinical role are analyzed.
