A 19-month-old patient was admitted for a 2-day history of worsening cough and dyspnea which required intubation. On examination, she was afebrile, with 60 breaths per minute, suprasternal indrawings, an oxygen saturation of 70%, and decreased breath sounds over the left hemithorax. A chest radiograph showed complete left opacity with mediastinal shift. A high-resolution CT scan of the chest ( ...

BACKGROUND Malignant pleural effusion is associated with short life expectancy and significant morbidity. A randomized controlled trial comparing indwelling pleural catheters (IPCs) with talc pleurodesis found that IPCs reduced in-hospital time and the need for additional procedures but were associated with excess adverse events. METHODS Using data from the clinical trial, we compared costs a...

Scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and X-ray diffraction (XRD) were used to study the effect of talc on crystallization properties morphology PVA/talc composite films from perspective heterogeneous nucleation effect. The Mo Zhishen equation Avrami kinetics behavior, successive self-nucleation annealing (SSA) method was analyze wafer thickness at various ...

Pleural effusions associated with malignancy (either malignant or paramalignant) pose diagnostic and therapeutic dilemmas for the clinician. This article reviews the common causes of malignant and paramalignant pleural effusions, pathogenesis, clinical presentation, chest radiography, pleural fluid characteristics, diagnosis, prognosis, and treatment. Talc, used either by poudrage or slurry, is...

A 75-year-old man who was diagnosed as having a fluid-filled giant bulla was treated with a modified Brompton technique due to his poor performance status. Percutaneous drainage, suction, and talc sclerotherapy through a Foley catheter can be good treatment options for patients with conditions that are too poor to allow surgical intervention, especially if there is adhesion between a giant bull...

-256 Wistar rats received a single injection into the right pleural cavity of UICC crocidolite in order to induce mesotheliomas. They were then given right intrapleural injections of BCG, crystalline silica, talc, carrageenan or saline (as a control). There was no significant change in the mesothelioma rate in the rats exposed to BCG, silica or talc, but there was a 3-fold increase in mesotheli...

Despite environmental monitoring, widely used occupational standards, and an increasing knowledge of the causative agents of occupational respiratory diseases, new cases of pneumoconiosis still occur. Pulmonary disorders caused by inhalation of talc (magnesium silicate, Mg,SI401, (OH)2) have been described among workers in various industries. " Interstitial inflammation with lymphocytic infiltr...

The lungs of eight drug addicts dying as a consequence of their habit have been examined. All showed the presence of small amounts of talc emboli and five the presence of starch emboli. Talc was invariably associated with a marked foreign body reaction which was insignificant in association with starch. Animal experiments showed very rapid (90% in 24 hours) removal of maize starch emboli; such ...

We thank Dr Aelony for his interest in our recent article in CHEST (June 2010) 1 on the occurrence of lung injury following thoracoscopic talc insuffl ation (TTI). We did not report on pleurodesis success rate because our goal was to determine the incidence of respiratory complications. We acknowledge the design limitations of our retrospective study. We carefully assessed all cases of postproc...
