[Side effects of percutaneous radiotherapy in the area of the thorax: cardiac toxicity of mantle field irradiation].

Radiation-induced cardiotoxicity is a factor not to be neglected, especially after mediastinal irradiation in Hodgkin's disease and Non-Hodgkin-Lymphoma. Caused by primary and secondary radiation lesions, cardiopathy may develop up to several years after treatment. Clinically, acute pericarditis is prevalent. To reduce cardiac long-term side effects, adequate radiation technique is crucial. Diagnosis and therapy in radiation-induced cardiopathy are presented.

[Nuclear magnetic resonance tomography of children's thorax].

Magnetic Resonance Imaging of the pediatric chest was performed in 53 patients. All examinations were performed using a 1.0 and 1.5 Tesla superconducting MR imager. 80% of the children were examined using anesthesia with a ventilation of 20% inspiration and 80% expiration. After performing the MR examination in 55% of the cases an operation was performed. In 29 patients anomalies of the brachiocephalic trunc were found. In four patients MR detected a doubled aortic arch, in four patients we found a dilated arch. In eight children a dilated pulmonary artery was diagnosed. In combination with eight tracheobronchoscopy, MR imaging proved to be the diagnostic method of choice for the evaluation of anomalies of the mediastinum. New developments like fast imaging techniques and 3D acquisition promise a further diagnostic improvement in the mediastinum.

[Radiologic study of the thorax using the digital method (FCR 101). Evaluation of various parameters as related to exposure].

A computed radiography system with solid state detectors (FCR 101) was employed to evaluate the quality of digital images, with optimal and progressively lowered doses, in the study of the chest. Routine chest radiographs of in patients with no pathologic conditions of the chest were studied. The patients were divided into 3 groups: each patient in group A underwent two radiographs, one at 100% and the other at 50% exposure; patients in group B were imaged with 100% and 25% doses, and those in group C received 50% and 25% exposure. Several parameters were employed for image evaluation, and a value was given to each of them (1 = good, 2 = sufficient, 3 = insufficient). Upon comparison of the average values obtained, we observed that the digital technique allowed a most accurate and well-defined representation of the examined parameters at 100% exposure dose and that a 50% reduction did not decrease the informative content in the least. A 25% reduction, however, determined a high degree of background noise and a subsequent, though slight, loss of information.

[Injuries of the thorax].

Within the period of 16 years (1973-1988) 692 patients with chest injuries were treated at the Military Medical Academy or 7% of all hospitalized patients with trauma. The largest source of trauma was traffic accidents (431 or 62.3%). Thoracotomy was performed in only 32 (4.6%) patients and the total mortality was 6.9% (48 traumatized). The importance of early recognition of vitally threatening syndromes and immediate initiation of therapeutical measures for correction of the disturbed intrathoracal relationship and hypovolemia have been pointed out.

[War injuries of the thorax. Aggressors and wound balistics].

War chest wounds are very common, but wound balistic notions are not known of physicians. Different threats are being listed, and we might retain the important rate of shrapnels wounds. Concerning the bullet behavior in soft tissue, one can discern full jacketed war bullets which may tumble after a variable "neck", and non jacketed missiles which cause wound through "mushrooming" and/or fragmentation effect. Buckshot wounds obey the rule of "all or none". Body reactions, particularly the clash with a hard material like bone, may overturn everything described in soft tissues. Every kind of possible chest wounds are analyzed from a ballistic point of view. We insist on the effects of so called terrible high velocity little bullets which do not wound because of an "explosive" shock wave, but with a fragmentation effect. The treatment sums up to the advice of good common sense which has had such a good effect on our masters.

[Radiologic picture of the thorax in acute asphyxia caused by near drowning. A caseload contribution].

One hundred-fifteen drowning and near-drowning patients were hospitalized in Jesolo and Mestre over the last 10 years. A correlation between radiological patterns and clinical features was thoroughly investigated by the authors. A close relationship was found between clinical findings and the X-ray pattern of the first radiography, taken immediately after the rescue. The longer the hospitalization (or when SNC is assessed) the less significant the correlation. According to the author's experience, prognosis is good when the first radiograph does not demonstrate any lesions. On the contrary, when lesions are seen on the first radiograph the patient is to be carefully monitored in order to treat every complication promptly, including ARDS (10% of all cases). Chest radiographs are also useful to explain autopsy findings. No typical radiological pattern was found: however, four signs were observed, which were very frequently associated-i.e., bilateral parenchymal shadows, pneumothorax, pneumopericardium, and gastrectasia. These findings appear to be characteristic of near-drowning.

[Computerized tomography in the staging and the follow-up of Hodgkin's lymphoma of the thorax].

As yet, the role of Computed Tomography (CT) as a routine imaging technique in the staging and follow-up of thoracic Hodgkin's disease has not been assessed. The authors report the results obtained in 120 patients affected with thoracic Hodgkin's disease, staged and followed by means of chest X-rays and CT. CT better identified intrathoracic involvement of mediastinal nodes, of lung parenchyma, of pleura, and of pericardial and chest walls in 54/120 patients (45%), with staging modifications in 18 (15%) of them only. Treatment was changed only in 12 patients (10%) where radiation therapy had been planned. The clinical value of the additional information yielded by CT was especially evident in the follow-up: CT allowed the correct evaluation of persistent/recurrent disease in 51/117 patients (43.5%), a figure high enough to suggest the use of CT in the routine follow-up of patients affected with thoracic Hodgkin's disease.
