Talc has been used historically in a wide range of industrial applications and consumer products. The composition and purity of talc used for industrial purposes can vary greatly depending on the source and may contain asbestos minerals. The developing science associated with the health risks of asbestos had an effect on the talc industry throughout the 20th century. This review presents a detailed analysis of the evolution of regulatory standards impacting the use of industrial talc in the U.S. from the early 20th century through the 1990s...

Introduction: Malignant pleural effusion (MPE) is common and currently in UK there are an estimated 50 000 new cases of MPE per year. Talc pleurodesis remains one of the most popular methods for fluid control. The value of thoracic ultrasound (TUS) imaging, before and after pleurodesis, in improving the quality and efficacy of care for patients with MPE remains unknown. Additionally, biomarkers of successful pleurodesis including measurement of pleural fluid proteins have not been validated in prospective studies...

Background: Pleural effusions constitute one of the most frequent pathologies encountered in the pulmonary service of Maputo Central Hospital (MCH) in Mozambique. Bleomycin and talc are commonly used for pleurodesis, but cost prohibitive, therefore we aimed to retrospectively compare the efficacy and safety of sodium hydroxide (NaOH) with bleomycin for pleurodesis. Methods: Case records of pleurodesis using bleomycin and NaOH from 2002 to 2013 were reviewed. Standard of care for pleurodesis for recurrent pleural effusions at MCH was developed using the materials available...

OBJECTIVE: To develop clay facial mask containing turmeric extract solid dispersion (TESD) for enhancing curcumin water solubility and permeability and to determine suitable clay based facial mask. METHODS: The TESD were prepared by solvent and melting solvent method with various TE to PVP K30 mass ratios. The physicochemical properties, water solubility and permeability were examined. The effects of clay types on physical stability of TESD, water adsorption and curcumin adsorption capacity were evaluated...

Importance: Indwelling pleural catheter and talc pleurodesis are established treatments for malignant pleural effusions among patients with poor prognosis. Objective: To determine whether indwelling pleural catheters are more effective than talc pleurodesis in reducing total hospitalization days in the remaining lifespan of patients with malignant pleural effusion. Design, Setting, and Participants: This open-label, randomized clinical trial included participants recruited from 9 centers in Australia, New Zealand, Singapore, and Hong Kong between July 2012 and October 2014; they were followed up for 12 months (study end date: October 16, 2015)...

The objective of the study was to examine adsorption of the aflatoxin B1 from synthetic gastric fluid and synthetic intestinal fluid by talc, raw and calcined diatomite. The kinetic and equilibrium adsorption processes were studied in the batch adsorption experiments applying high performance liquid chromatography for the aflatoxin B1 determination. The kinetic study showed a very fast adsorption of the aflatoxin B1 onto the selected adsorbents from the both physiological fluids with reaching equilibrium within 1-15min...

BACKGROUND: Talc poudrage during thoracoscopy is considered the standard procedure for patients with symptomatic malignant pleural effusion (MPE). Until now, no alternative technique other than talc poudrage for pleurodesis during medical thoracoscopy has been proposed. Liquid sclerosants, such as mistletoe extract, have been sprayed evenly into the pleural cavity during semirigid pleuroscopy for chemical pleurodesis. OBJECTIVE: We conducted a retrospective study using the database of semirigid pleuroscopy to identify the usefulness of pleurodesis using a mistletoe extract delivered via a spray catheter during semirigid pleuroscopy for symptomatic MPE...

Talc has been used for over a century in a variety of cosmetic products. While pure cosmetic talc (free of asbestos) is not considered a risk factor for mesothelioma, it has been recently suggested that inhalation of cosmetic talc containing trace levels of asbestos is a risk factor for mesothelioma. Bulk analyses of cosmetic talcum products were performed in the 1960s and 1970s, however, the analytical methods used at that time were incapable of determining whether asbestos minerals were present in the asbestiform versus non-asbestiform habit...

The purpose of this article is to report a case of hemoptysis occurring in combination with secondary spontaneous pneumothorax following chemical pleurodesis by talc. A Japanese male with cancer of renal pelvis was found with the left pneumothorax and multiple lung metastases. A computed-tomography scan revealed severe emphysema throughout the lungs. Talc pleurodesis was employed to arrest air leakage. The patient developed hemoptysis 45 minutes after talc injection into the thorax. This is the first report of hemoptysis following talc pleurodesis...

Optimal management of malignant pleural effusion (MPE) is important in the care of patients with advanced cancer. Surgical (especially video-assisted thoracoscopic surgery (VATS)) and non-surgical strategies are available. Clinicians should be aware of the evidence supporting the use of different modalities to guide treatment choice. Areas covered: This review covers published evidence of the advantages and disadvantages of VATS and non-surgical alternatives for MPE management. Expert commentary: Randomized clinical trials (RCTs) are needed to define the roles and benefits of VATS as existing literature is often flawed by selection bias...

Evaluation of diphenhydramine in talc induced type 2 diabetes mellitus was done in Wistar rats. Oral administration of Talc (10mg/kg)carried out for 21days increased the levels of serum glutamate pyruvate transaminase (SGPT), glutamate oxaloacetate transaminase (SGOT), serum creatinine, blood glucose, urea, uric acid and triglycerides (TGs), but when the animals were treated with diphenhydramine (DPH), the levels of the aforementioned biochemical parameters decreased significantly (p<0.0001). The level of serum cholesterol and high density lipoprotein (HDL) was found to be reduced in Diabetes Mellitus (DM) control and when it was treated with DPH control animals, these makers increased significantly...

OBJECTIVE: Talc is widely used in industrial applications. Previous meta-analyses of carcinogenic effects associated with inhaled talc included publications before 2004, with a lack of data in China, the largest talc-producing country. The safety of workers exposed to talc was unclear due to limited evidence. The objective of this study was to reevaluate the association between inhaled talc and lung cancer. SETTING PARTICIPANTS AND OUTCOME MEASURES: A meta-analysis was performed to calculate the meta-SMR of lung cancer...

BACKGROUND: Seroma formation remains a common complication after an incisional hernia repair. The use of surgical drains is widespread, but evidence for their use and other adjuncts is limited. Our aim was to perform a systematic review of the literature on techniques used to reduce the incidence of post-operative seroma formation. METHODS: A systematic search of PubMed and Embase databases was conducted using terms including "incisional hernia" and "seroma". All studies on adults undergoing open incisional hernia repair with at least one intervention designed to reduce seroma formation were included...

Titanium dioxide is a metal oxide used as a white pigment in many food categories, including confectionery. Due to differences in the mass fraction of nanoparticles contained in TiO2, the estimated intakes of TiO2 nanoparticles differ by a factor of 10 in the literature. To resolve this problem, a better estimation of the mass of nanoparticles present in food products is needed. In this study, we focused our efforts on chewing gum, which is one of the food products contributing most to the intake of TiO2. The coatings of four kinds of chewing gum, where the presence of TiO2 was confirmed by Raman spectroscopy, were extracted in aqueous phases...

BACKGROUND: General anesthesia and endotracheal intubation are a luxury rather than a necessity for many video-assisted thoracic surgery (VATS) operations. Twenty-three years ago the author began utilizing local anesthesia and sedation for pleural disease and subsequently for pericardial and lung disease. STUDY DESIGN: The records of all patients undergoing VATS utilizing local anesthesia and sedation at hospitals of the Geisinger Health System (Danville and Wilkes-Barre, PA) June 1, 2002 to June 30, 2011 and the Lifebridge Health System (Baltimore, MD) July 1, 2011 to March 1, 2017 were retrospectively reviewed...
