Objective Pleurodesis is an effective therapy for malignant pleural effusion (MPE). While interstitial lung disease (ILD) has been regarded as a serious complication of pleurodesis, its clinicopathological characteristics have not been fully understood. This study was conducted to elucidate the incidence of ILD and the risk factors for ILD in patients who underwent pleurodesis to control MPE. Methods The medical records of patients who underwent pleurodesis in Aichi Medical University between March 2008 and February 2013, the period before the approval of talc in Japan, were retrospectively analyzed...

BACKGROUND: It is well known that powdery drugs such as cocaine and heroin are frequently adulterated or diluted predominantly to obtain more doses and to increase the drug dealer's profits, but also to enhance, to modify or to oppose drug effects. METHODS: The aim of this report is to provide an overview of the recent scientific literature on medicines as well as on new psychoactive substances, used as cutting agents (i.e. pharmacologically active adulterants) and on the related adverse health effects on consumers, possibly due to the synergistic effect of the adulterants laced with substances of abuse, which represent a matter of great concern because of the frequent fatalities...

The Eridania region in the southern highlands of Mars once contained a vast inland sea with a volume of water greater than that of all other Martian lakes combined. Here we show that the most ancient materials within Eridania are thick (>400 m), massive (not bedded), mottled deposits containing saponite, talc-saponite, Fe-rich mica (for example, glauconite-nontronite), Fe- and Mg-serpentine, Mg-Fe-Ca-carbonate and probable Fe-sulphide that likely formed in a deep water (500-1,500 m) hydrothermal setting...

Application of polyhydroxybutyrate (PHB) to plastic industry has expanded over the last decades due to its attracting features over petro-based plastic, and therefore, its waste accumulation in nature is inevitable. In the present study, a total of four bacterial strains, viz., MK3, PN12, PW1, and Lna3, were formulated into a consortium and subsequently used as biological tool for degradation of biopolymers. The consortium was tested through λ max shifts under in vitro conditions for utilization of PHB as sole carbon source...

OBJECTIVE: Due to some historical (and inaccurate) reports that asbestos might be present in some cosmetic talc products, questions are occasionally raised regarding the potential pleural mesothelioma risks associated with cosmetic talc products. Our objective was to determine the incidence of pleural mesothelioma of individuals exposed to cosmetic talc. MATERIALS AND METHODS: We conducted a systematic review of the epidemiological literature for cosmetic talc miners and millers and found three occupational cohort studies that evaluated pleural mesothelioma incidence in workers in Italy, Norway, France, and Austria...

Various clinical trials have been published on the optimal clinical management of patients with pleural exudates, particularly those caused by malignant tumors, while little information is available on the diagnosis and treatment of pleural transudates. The etiology of pleural transudates is wide and heterogeneous, and they can be caused by rare diseases, sometimes constituting a diagnostic challenge. Analysis of the pleural fluid can be a useful procedure for establishing diagnosis. Treatment should target not only the underlying disease, but also management of the pleural effusion itself...

BACKGROUND AND IMPORTANCE: Dissection of cerebellopontine angle (CPA) tumors that abut or adhere to the brainstem or cranial nerves can be a challenging surgical endeavor. We describe the use of semitranslucent latex rubber pledgets in the tumor-brain interface as a method to improve visualization and protection of vital tissue during microsurgical dissection of CPA masses. The rubber pledgets are fashioned by cutting circular discs out of the cuff portion of talc-free, partially opaque latex gloves...

BACKGROUND: Symptomatic malignant pleural effusion (MPE) occurs frequently in patients with metastatic cancer. The associated prognosis is poor and the success rate of talc pleurodesis (TP) is low. Indwelling pleural catheters (IPCs) are commonly inserted when TP has been unsuccessful. METHODS: We compared talc pleurodesis with the use of an indwelling pleural catheter in patients with recurrent MPE in a multicenter randomized controlled trial (superiority design)...

Organic-inorganic hybrid layered materials are proposed as additives in a quasi-solid gel electrolyte for dye-sensitized solar cells. Talcs could provide a low-cost and environmentally friendly, as well as abundant, option as gelators. Here, talcs were prepared by functionalizing an organotalc with three polyamidopyridine dendron generations, PAMPy-talc-Gn (n = 1, 2 and 3). PAMPy dendrons grow parallel to the lamellae plane and form an organized structure by intermolecular interactions. In addition, polyiodide-dendron charge-transfer complexes were prepared onto the organotalc by adsorption of iodine...

BACKGROUND: The suggestion that spontaneous pneumothorax (SP) may result from diffuse porosity rather than discrete anatomic abnormality challenges the practice of targeted bullectomy. We assessed whether underlying pulmonary abnormalities are correlated or could be predicted from the mode of presentation, with potential implications for treatment. METHODS: We analyzed 192 consecutive video-assisted thoracoscopic surgery resections for SP (139 primary, 53 secondary) in 171 patients (115 male, age 36, range, 16 to 81)...

This paper provides a recapitulation of the position of the British Thoracic Society and the American College of Chest Physicians based on a review of the literature concerning the current methods of diagnosing and treating primary spontaneous pneumothorax (PSP). The previously developed guidelines were re-evaluated in 2015 by a task force of the European Respiratory Society (ERS). They are intended to be used by surgeons as well as emergency and pulmonary ward physicians, and they apply largely to emergency procedures...

We attempted to study the compatibility among plant beneficial bacteria in the culture level by growing them near in the nutrient agar plates. Among all the bacteria tested, Rhizobium was found to inhibit the growth of other bacteria. From the compatible group of PGPR, we have selected one biofertilizer (Azospirillum brasilense strain TNAU) and one biocontrol agent (Pseudomonas fluorescens strain PF1) for further studies in the pot culture. We have also developed a bioformulation which is talc powder based, for individual bacteria and mixed culture...

The size, shape and distribution of different phases in thermoplastic polyolefin (TPO) blends and composites are critical to the properties of the materials, but can be difficult to characterise. Here we report the combination of heavy metal staining and focused ion beam - scanning electron microscopy (FIB-SEM) to reveal the three-dimensional (3D) structure of an elastomer-modified poly(propylene) and a talc filled elastomer-modified poly(propylene). High-quality, high-resolution serial images were collected and the 3D structures were characterised quantitatively...

Ovarian cancer (OC) is the seventh most commonly diagnosed cancer among women in the world and the tenth most common in China. Epithelial OC is the most predominant pathologic subtype, with five major histotypes that differ in origination, pathogenesis, molecular alterations, risk factors, and prognosis. Genetic susceptibility is manifested by rare inherited mutations with high to moderate penetrance. Genome-wide association studies have additionally identified 29 common susceptibility alleles for OC, including 14 subtype-specific alleles...

PURPOSE OF REVIEW: The current review describes the latest evidence in the management of malignant pleural effusions (MPE). RECENT FINDINGS: Daily drainage of indwelling pleural catheters achieved auto-pleurodesis at a higher rate compared with every-other-day drainage [0.47 vs. 0.24; difference in proportion of 0.23; 95% confidence interval (CI) 0.08-0.38; P = 0.003]. In patients with MPE undergoing talc pleurodesis, a large multicenter randomized clinical trial found that pain control with opiates vs...
