[Anxiety and depression in emodialysis].

The patients in terminal uremia show anxiety and depression correlate with anagraphic and dialytic age, here evidenced trought the Hospital Anxiety and Depression Scale (HADS). In a cohort of 120 patients, only 100 have been selected, because of incompatibility (11.6%) or refusal (5%).

[Bronchiolo-alveolar carcinoma. The computed tomographic picture and histological correlations].

Twenty-one CT examinations of 18 patients with a known bronchioloalveolar carcinoma in the lung were retrospectively reviewed to describe the CT features of bronchioloalveolar carcinomas. Surgical specimens were available in 13 cases in which CT-histologic correlation was also obtained. In 5 patients the diagnosis was made with cytology and confirmed with radiologic-clinical follow-up.

Carcinomatous solitary pulmonary nodules: evaluation of the tumor-bronchi relationship with thin-section CT.

To investigate the value of computed tomography (CT) for depicting the relationship between carcinomatous solitary pulmonary nodules and the bronchial tree and predicting the results of various bronchoscopic biopsy techniques, the authors retrospectively reviewed CT scans from 27 consecutive patients with solitary pulmonary nodules associated with a positive bronchus sign. All patients underwent bronchoscopy and transbronchial biopsy. Macroscopic demonstration of the tumor-bronchi relationship was obtained in 18 patients.

[Contribution of computerized tomography to the diagnosis of patients with non-calcified solitary pulmonary nodule, without known neoplasm].

We define a solitary pulmonary noncalcified nodule (NPS) as a single focal rounded or ovoid lesion in the lung parenchyma, less than 4 cm in diameter, without associated adenopathy, atelectasis or pneumonia. An NPS, in the absence of a known primary malignancy, can be lung cancer (NPSM), a metastasis of unknown origin (NPSMT), or a benign lesion (NPSB). The best approach to the management of NPS and the value of CT are still controversial and uncertain.

Bronchus sign on CT in peripheral carcinoma of the lung: value in predicting results of transbronchial biopsy.

The bronchus sign on CT represents the presence of a bronchus leading directly to a peripheral pulmonary lesion. We investigated the value of this sign in predicting the results of transbronchial biopsy and brushing in 33 consecutive cases of proved peripheral bronchogenic carcinoma studied with thin-slice CT (2-mm-thick sections). The bronchus sign was seen on CT in 22 patients and was absent in 11.
