INTRODUCTION: Talc pleurodesis is a well-established procedure performed to obliterate the pleural space to prevent recurrent pleural effusion and/or recurrent pneumothorax. Pleurodesis is commonly accomplished by draining the pleural fluid, if present, followed by either a mechanical procedure, such as abrasion, pleurectomy, or instillation of a chemical irritant into the pleural space, which results in inflammation and fibrosis which obliterates the pleural space. The reported complications of talc pleurodesis are hypoxemia, hypotension, tachycardia, dyspnea, chest pain, and fever...

The objective of this study was to explain curing phenomena for pellets coated with a flexible polymeric coating based on poly(vinyl acetate) (Kollicoat(®) SR 30D) with regard to the effect of starter cores, thickness of drug layer, adhesion of coating to drug-layered-cores as well as coating properties. In addition, appropriate approaches to eliminate the curing effect were identified. Sugar or MCC cores were layered with the model drugs carbamazepine, theophylline, propranolol HCl, tramadol HCl and metoprolol HCl using HPMC (5 or 25% w/w, based on drug) as a binder...

Recent studies demonstrated potential effects of stem cells on cardiac function in heart failure. However, influences of the technique of application remained undetermined. In the present study, the pericardial sac was used as depot for fluorescent-labeled mesenchymal stem cells in rats. To evaluate influences of inflammation on cell homing, a sterile pericarditis was induced by talc. It is shown that intrapericardial stem cells application is sufficient to provide myocardial penetration. The extent of homing was amplified by inflammation in a talc-induced pericarditis...

BACKGROUND: Fluorodeoxyglucose (FDG) uptake on positron emission tomography (PET) scan is an indicator of potential malignancy or infection. Patients with a history of talc pleurodesis can develop pleural or lung parenchymal nodules/talcomas. In these patients, talc-associated (non-malignancy-related) FDG uptake may occur over years. CASE REPORT: A 66-year-old female presented with a past medical history significant for resected non-small-cell lung cancer and was treated with chemotherapy/radiation...

Some epidemiological studies suggest an association between genital use of talc powders and increased risk of ovarian cancer, but the evidence is not consistent. We performed a meta-analysis of epidemiological studies to formally evaluate this suspected association. A systematic search was conducted in Medline, Embase, and Scopus, leading to the identification of 24 case-control studies and three cohort studies, including 302 705 women with ovarian cancer. In the meta-analysis, we used a random-effect model to calculate summary estimates of the association between genital use of talc and occurrence of ovarian cancer...

BACKGROUND AND PURPOSE: A major challenge in CT screening for lung cancer is limited specificity when distinguishing between malignant and non-malignant pulmonary nodules (PN). Malignant nodules have different mechanical properties and tissue characteristics ('stiffness') from non-malignant nodules. This study seeks to improve CT specificity by demonstrating in rats that measurements of volumetric ratios in PNs with varying composition can be determined by respiratory-gated dynamic CT imaging and that these ratios correlate with direct physical measurements of PN stiffness...

BACKGROUND AND OBJECTIVE: Malignant pleural effusion is associated with morbidity and mortality. A randomized controlled trial previously compared clinical outcomes and resource use with indwelling pleural catheter (IPC) and talc pleurodesis in this population. Using unpublished quality of life data, we estimate the cost-effectiveness of IPC compared with talc pleurodesis. METHODS: Healthcare utilization and costs were captured during the trial. Utility weights produced by the EuroQol Group five-dimensional three-level questionnaire and survival were used to determine quality-adjusted life-years (QALYs) gained...

The Food and Drug Administration (FDA, the Agency, or we) is amending its regulation on uses of ozone-depleting substances (ODSs), including chlorofluorocarbons (CFCs), to remove the designation for certain products as "essential uses" under the Clean Air Act. Essential-use products are exempt from the ban by FDA on the use of CFCs and other ODS propellants in FDA-regulated products and from the ban by the Environmental Protection Agency (EPA) on the use of ODSs in pressurized dispensers. The products that will no longer constitute an essential use are: Sterile aerosol talc administered intrapleurally by thoracoscopy for human use and metered-dose atropine sulfate aerosol human drugs administered by oral inhalation...

An innovative dry powder coating technology was developed in a high-shear granulator using ethylcellulose (E10) as polymer. Several solid plasticizers were investigated with the aim of decreasing the polymer Tg at least to the highest possible working temperature (80°C). DSC analysis of physical mixtures of E10 and plasticizers evidenced that lauric acid (LA) was the most effective plasticizer. In order to reach the target temperature a liquid plasticizer, oleic acid (OA), was introduced in the coating formulation...

Eosinophilic cholecystitis (EC) is a rare inflammatory condition of the gallbladder, confirmed by a cellular infiltrate comprised of more than 90% eosinophils in the gallbladder wall on histological examination. Although the etiology of EC is largely unknown, local autoimmune reactions within the gallbladder wall to inflammatory mediators from distal sites of inflammation have been hypothesized. Talc pleurodesis (TP) is a common clinical procedure used within respiratory medicine. However, it is associated with activation of systemic acute inflammatory responses including an increase in serum interleukin-8 (IL-8), which is a potent mediator of eosinophil chemotaxis...

Postbloom fruit drop (PFD) caused by Colletotrichum acutatum affects flowers and causes early fruit drop in all commercial varieties of citrus. Biological control with the isolate ACB-69 of Bacillus subtilis has been considered as a potential method for controlling this disease. This study aimed to develop and optimize a B. subtilis based-formulation with a potential for large-scale applications and evaluate its effect on C. acutatum in vitro and in vivo. Bacillus subtilis based-formulations were developed using different carrier materials, and their ability to control PFD was evaluated...

We present a case of transpupillary argon laser cyclophotocoagulation (TALC) in a patient with traumatic aniridia and aphakia secondary to blunt trauma who had previous bilateral trabeculectomy. Four months after the trauma the patient's intraocular pressure (IOP) rose to 35 mmHg despite topical antiglaucomatous medication. Inferior 180 degrees cyclophotocoagulation was performed with transpupillary argon laser in the first session and his IOP fell to values of 12-17 mmHg. Twelve weeks after TALC, his IOP rose to 22 mmHg and we had to apply TALC to the residual ciliary processes...

BACKGROUND Lymphangioma is an atypical non-malignant, lymphatic lesion that is congenital in origin. Lymphangioma is most frequently observed in the head and neck, but can occur at any location in the body. About 65% of lymphangiomas are apparent at birth, while 80-90% are diagnosed by two years of age. Occurrence in adults is rare, as evidenced by less than 100 cases of adult lymphangiomas reported in the literature. CASE REPORT A 36-year-old Indian woman with a medical history of recurrent pleural effusions presented with chief complaints of dyspnea on exertion for one year and a low-grade fever for one month...
