INTRODUCTION The management of recurrent malignant pleural effusions (MPE) can be challenging. Various options are available, with the most efficacious and widely used being talc pleurodesis. Talc can either be applied via a chest drain in the form of slurry, or at medical thoracoscopy using poudrage. Current evidence regarding which method is most effective is conflicting and often methodologi...

Malignant pleural effusion (MPE) is common in most patients with advanced cancer, especially in those with lung cancer, metastatic breast carcinoma and lymphoma. This complication usually leads patients to suffer from significant dyspnea, which may impair their mobility and reduce their quality of life. In patients with MPE, several interventions have been shown to be useful for palliation of t...

The reaction talc 1 forsterite 5 enstatite 1 H2O has been investigated between 6 and 20 kbar. Previous high-pressure experimental studies suggested various reaction positions, mostly with positive P-T slopes. The new results show that the reaction has a negative slope in the pressure range studied. It was bracketed between 640 and 680 8C at 10 kbar, between 620 and 640 8C at 15 kbar, and betwee...

The adsorptions of reactive procion brilliant red H-EGXL and procion yellow H-EXL by various clay adsorbents were investigated in this research. The research showed that synthetic talc has the highest adsorption capacity for decolorization of both procion type of reactive dyes compared with other clay adsorbents. The removal efficiencies of synthetic talc relatively stable above 80% until the i...

OBJECTIVE Some concern still exists regarding long-term lung function following videothoracoscopic talc poudrage for primary spontaneous pneumothorax (PSP). We evaluated lung function at 5 years in a series of 100 patients surgically treated for PSP. METHODS Out of 1065 patients treated for PSP by means of videothoracoscopic talc poudrage from September 1995 to January 2006, we consecutively ...

From 1978 to 1985 96 patients with their first spontaneous pneumothorax were randomised into three groups, receiving either treatment with simple drainage (34 patients), drainage with tetracycline pleurodesis (33 patients), or drainage with talc pleurodesis (29 patients). There were 58 men and 38 women, aged 18-88 years. There was no significant difference between the three groups in the mean t...

Thoracoscopic talc poudrage of the entire pleural surface constitutes successful treatment of recurrent pneumothorax in cystic fibrosis (CF); however, subsequent lung transplantation is seriously jeopardized due to the development of extensive pleural adhesions. We describe a 27-year-old patient with CF with recurrent right-sided pneumothorax, refractory to chest tube drainage and to chemical (...

a brief account of the representative and workable industrial minerals namely magnesite, talc and barite in lesser himalaya, is presented here emphasizing their genesis. deposits of magnesite and talc are found associated with neoproterozoic, plateform type, shelf-slope limestone-dolomite host rocks from inner lesser himalayan sequences. field, textural, geochemical signatures and fluid inclusi...
