OBJECTIVE Prospectively assess the performance of diffusion-weighted magnetic resonance imaging (DW-MRI) for differentiation of central lung cancer from atelectasis. MATERIALS AND METHODS 38 consecutive lung cancer patients (26 males, 12 females; age range: 28-71 years; mean age: 49 years) who were referred for thoracic MR imaging examinations were enrolled. MR examinations were performed usi...

BACKGROUND In children with lower respiratory tract symptoms, the elicited signs are not enough to distinguish common diagnosis like pneumonic consolidation, foreign body aspiration and atelectasis. Radiology and bronchoscopy would identify the true nature of the etiology. DESIGN Prospective study. SUBJECTS Thirty five children with both acute and chronic lower respiratory tract symptomatol...

intraoperative radiation therapy (iort) is a multidisciplinary approach in which residual tumors or tumor beds are directly irradiated during a surgical procedure. to evaluate its efficacy, from 1985, we conducted a prospective study including non-metastatic gastric adenocarcinoma treated by surgery, iort (15 grays) and postoperative external beam radiotherapy (44 grays). up to 1993, 51 cases o...

Objective To analyze the radiological aspects of pulmonary atelectasis in newborns on mechanical ventilation and treated in an intensive care unit, associating the characteristics of atelectasis with the positioning of the head and endotracheal tube seen on the chest X-ray, as well as with the clinical variables. Materials and Methods This was a retrospective cross-sectional study of 60 newbo...

natural rubber latex is the second most implicated agent in intraoperative anaphylactic reactions. this report describes a case of intraoperative anaphylaxis occurring in a non-atopic fourteen-year-old girl undergoing multiple surgical procedures, but without spina bifida, in which latex surgical gloves were the main culprit for the anaphylactic reactions. clinical manifestations of an anaphyla...

Background: Pulmonary atelectasis is common following sternotomy for cardiac surgery. The degree of atelectasis present on chest x-ray has been used to assess efficacy of interventions designed to reduce atelectasis, however radiological atelectasis scoring systems used may exaggerate the clinical effect of atelectasis in these patients. We have produced an alternative scoring system that seeks...

BACKGROUND High concentrations of inspired oxygen are associated with pulmonary atelectasis but also provide recognized advantages. Consequently, the appropriate inspired oxygen concentration for general surgical use remains controversial. The authors tested the hypothesis that atelectasis and pulmonary dysfunction on the first postoperative day are comparable in patients given 30% or 80% perio...

UNLABELLED Atelectasis caused by general anesthesia is increased in morbidly obese patients. We have shown that application of positive end-expiratory pressure (PEEP) during the induction of anesthesia prevents atelectasis formation in nonobese patients. We therefore studied the efficacy of PEEP in morbidly obese patients to prevent atelectasis. Twenty-three adult morbidly obese patients (body ...
