Does mechanical pleurodesis result in better outcomes

One large cohort study compared the outcomes of mechanical and chemical talc pleurodesis and reported a significant reduction in recurrence with talc pleurodesis in comparison with pleurectomy (1.79 vs. 9.15%, P = 0.00018). Another large cohort study, analysing pleural abrasion, pleurectomy and talc pleurodesis, both in isolation and in combination with apical bullectomy, reported the highest ...

Comparative study of talc poudrage versus pleural abrasion ...

18/04/2012  In conclusion, the results of this study lead us to consider abrasion and talc poudrage as effective and valid techniques for pleurodesis. Moreover, talc poudrage patients present with lower morbidity and less surgical time, although significant differences have not been observed between both techniques with regard to the recurrence of pneumothorax. Conflict of interest: none declared ...

Comparative study of the extrinsic properties of poly ...

The compression molded sheets showed a reduction in abrasion by greater than 69% for either filler type compared to the neat PLA due to their high stiffness. In contrast, only the talc provided barrier properties that hindered both water and oxygen permeability, while biocarbon did not possess a high aspect ratio to form a tortuous path necessary for barrier improvement. Yet, the biocarbon ...

Talc - an overview ScienceDirect Topics

Talc is a hydrated magnesium silicate (Mg 3 Si 4 O 10 (OH) 2), with small, varying amounts of aluminum, iron, and calcium oxides, depending on the mining site. It is soft (Mohs hardness of 1.0), with low abrasion and a slippery texture, and it is highly oleophilic. The form used commercially is plate-like (Figure 4.4), with an aspect ratio of ...

27/05/2020  Chung et al. reported an RCT that compared 3 types of interventions, blebectomy and abrasion, dextrose and pleural abrasion and dextrose plus talc chemical abrasion without any mechanical pleural abrasion . From this study, only the first group (single intervention) and the second group (combined intervention) were included in this meta-analysis. We excluded the third group

The efficacy of mechanical abrasion and talc slurry as ...

Methods: Group I dogs had mechanical abrasion (MA) of the pulmonary and costal pleurae performed in one hemithorax with a dry gauze sponge with a median sternotomy approach. Group II dogs had 100 mL of a 1 g talc slurry (TS) administered into one hemithorax through a tube thoracostomy. Administration of the TS was visualized by using video thoracoscopy. All dogs were evaluated at 2, 10, 20 ...

EFFECT OFOOFFOF TALC ON ROLLING RESISTANCE INIINNIN

Although talc has a slight effect on abrasion resistance of black compounds, it did not change the wear performance in precipitated silica reinforced vulcanizates. Talc did not affect the adhesion between the tread compound and the carcass. INTRODUCTION Talc is a natural occurring mineral. Pure talc is hydrous magnesium silicate consisting of a brucite sheet sandwiched between two silica ...

Effectiveness of chemical pleurodesis in spontaneous ...

When talc is used in patients undergoing surgical (VATS) procedures, the recurrence rate appears to be low (between 0.0% and 3.2%) and it seems that the addition of talc contributes to a lower recurrence compared with VATS bullectomy and either drainage or abrasion alone. There have been no direct comparisons of VATS bullectomy and pleurectomy to VATS bullectomy and talc pleurodesis. Results ...

Pleurodesis - an overview ScienceDirect Topics

Mechanical abrasion of the visceral and parietal pleura via thoracoscopy is known as mechanical pleurodesis. The abrasion induces petechial bleeding, which results in diffuse inflammation and leads to fibrin deposition in a fashion similar to the chemical sclerosants. Although no head-to-head comparisons between chemical and mechanical pleurodesis have been conducted, similar outcomes to ...

Talc pleurodesis - Royal Victoria Hospital, Belfast

Talc powder is puffed into the pleural cavity to cover the surface of the lung and the inside of the ribs. (Talc is similar to the talcum powder one uses in the bathroom but is prepared sterile to medical grade). The talc induces an inflammatory reaction which glues the lung to the inner surface of the ribcage. In time these mature into scar tissue forming permanent adhesions. With the lung ...

VATS Partial Pleurectomy Versus VATS Pleural Abrasion ...

Recently, Joharifard et al. did show a significant reduction in recurrence of SP after pleurectomy compared to pleural abrasion in a pediatric patient population. Interestingly, this study did also show a rather high recurrence rate after pleural abrasion (40%). Reasons for the higher recurrence rate remain unclear, as no other clinical factor did differ between the two groups except for the ...

Talc Milling Mineral Industries Hosokawa Micron ...

Talc is a clay mineral made of hydrated magnesium silicate. Talc is formed from metamorphic reaction of minerals in aqueous conditions. Talc is one of the softest minerals on earth, with a Mohs hardness of 1.0 (defining mineral). However, some abrasive impurities (such as quartz or sand) may be present in the mined talc. It is typically in a foliated structure. Talc has natural dry lubrication ...

Talc Omar Group

Because talc is very soft (1 on MOHS hardness scale), it causes only minimal abrasion to process and application equipment. It disperses readily in both aqueous and solvent-based paints. Talc having a surface area greater then 12 m2/g is used for gloss control when an exact degree of Sheen or luster is required. Omtalc has the ability to fulfill all major criterions for the paint industry. Our ...

Talc Powder ESAAR

Talc increases coverage and weather resistance of the products. The use of talc creates a barrier effect, which limits the penetration of water and corrosive agents into paints and coatings. This properties lead to a reduction in bubble formation, corrosion and peeling. Talc is used as an extender and filler in paints. The platy shape of talc particles improves the suspension of solids in the ...

MICRONIZED TALC: A COST-EFFECTIVE FUNCTIONAL FILLER FOR ...

In fact, a generic size reduction process with a generic talc source cannot provide the proper final characteristics of fine talc: similar particle size distribution could be reached, but performances in the final application could result significantly different. A consolidated know- how in source selection, processing and downstream applications is necessary to produce an effective functional ...

Non-steroidal anti-inflammatory drugs decrease the

Reduction of the recurrence rate could be obtained by training surgeons not to overlook blebs during the procedure, consider widening the area of pleurodesis, and/or perform apical pleurectomy [12, 13]. The objective of the present study was to assess if NSAIDs affect the quality of pleurodesis resulting from mechanical abrasion in pigs. We hypothesized that the current use of NSAIDs ...
