Comparative Study[The scintigraphic prediction of residual lung function after lobectomy in patients with bronchial carcinoma].
The scintigraphic prediction of residual pulmonary function after pneumonectomy has been validated in a number of studies while scintigraphy is not standardized in case of lobectomy. This study was aimed at investigating the accuracy of the scintigraphic prediction of post-lobectomy lung function using Wernly method. ⋯ A good correlation between predicted and observed data was obtained in both the pneumonectomized group (r = 0.77 and 0.78 for CV and VEMS, respectively; p < 0.005) and the lobectomized group (r = 0.74 and 0.79 for CV and VEMS, respectively: p < 0.005). It can be concluded that the method used for the scintigraphy prediction of post-lobectomy pulmonary function is as accurate as the post-pneumonectomy method and can be used reliably in the clinical practice.

Comparative Study[CT-guided transthoracic needle aspiration of solitary lung lesions. Personal experience in 118 cases].
Fast-scan CT is widely and frequently used to guide fine-needle aspiration biopsy (FNAB) of questionable lung nodules. To investigate technical problems, complications, diagnostic accuracy and indications of this technique, the findings were reviewed relative to 118 patients with negative transbronchial biopsy and sputum cytology who underwent CT-guided FNAB of solitary lung lesions. Over a 25-month period, 73 men and 45 women underwent CT-guided FNAB of lung lesions. ⋯ CT allowed the lesions to be approached easily and precisely, which is useful especially in small, peripheral or hilar, nodules missed or poorly defined by radiology. To conclude, CT-guided transthoracic FNAB can be suggested as the method of choice to diagnose lung lesions which are difficult to puncture endoscopically because of size or location, and in suspected metastases. Moreover, FNAB can be used as second-line method in the lesions where endoscopic biopsy cannot be performed or whose findings are negative.

Case Reports Comparative Study[Pneumoperitoneum caused by thoracic injury].
Among the various causes of free abdominal gas, there should be included those following chest injuries. In these cases, pneumoperitoneum may develop as a consequence of different physio-pathologic mechanisms and can be associated with pneumothorax and/or pneumomediastinum and/or retropneumoperitoneum. ⋯ In this trial, the authors investigated the clinical and semiologic meaning of this finding, frequently disregarded in traumatologic literature, which was observed in 6 cases of chest injuries: 4 blunt and 2 penetrating traumas. In this condition, even though conventional radiology remains the method of choice, CT can be considered as an integrative technique of great panorama allowing small amounts of free abdominal gas and related thoracic and abdominal injuries to be demonstrated, especially in the patients in forced supine decubitus, in whom abdominal plain films can be difficult to perform.

Comparative Study[Anesthesiological problems in magnetic resonance].
A prospective study was carried out on 68 patients examined with Magnetic Resonance Imaging (MRI) under general anesthesia. Mean patients age was 10 years (range: 9 days to 77 years). MRI was performed with a 1.5 T superconductive magnet and different anatomical regions were studied: the brain in 63 cases, the lumbar spine in 3, the cervical spine in 1 and finally the upper abdomen in 1 patient. ⋯ Minor complications occurred in 5 more patients. Image quality was excellent in 75% of cases, while few movement artifacts were observed in the extant 25%. To conclude, isoflurane anesthesia is a safe, effective and efficient type of sedation for the patients to be submitted to MRI which can be used also on an outpatient basis.
