To evaluate the efficiency of pleurodesis (PD) in the management of symptomatic malignant pleural effusion (PE) in breast cancer, we reviewed 46 patients undergoing 49 PDs. When radiotherapy was part of the initial treatment, 41% of PEs were ipsilateral to the primary, if not, 85% of PEs were ipsilateral (P < 0.0075). Six percent of patients presented dyspneic with exertion, 32% during daily routine; 61% at rest. All except 1 were improved after PD; 74% had no dyspnea, 23% had exertional dyspnea. PD relieved chest pain in 4 and cough in 5 patients. With 31 Talc/Iodine PDs, 2 mortalities and 2 minor complications occurred. Of 17 tetracycline PDs, 1 was complicated by bronchopleural fistula and 1 failed. 1 Mustine PD was uncomplicated. Survival at 6, 12, and 24 months was 58%, 40%, and 13%, respectively. Primary local radiotherapy may prevent ipsilateral PE. Talc/Iodine and tetracycline PD reliably provide relief from the distressing symptoms of malignant PE.

Asthma is a chronic airway disorder characterized by recurrent attacks of breathlessness and wheezing, affecting 300 million people around the world (available at: www.who.int). To date, genetic factors associated with asthma susceptibility have been unable to explain the full etiology of asthma. Recent studies have demonstrated that the epigenetic disruption of gene expression plays an equally important role in the development of asthma through interaction with our environment. We sensitized 6-week-old C57BL/6J mice with house-dust-mite (HDM) extracts intraperitoneally followed by 5 weeks of exposure to HDM challenges (three times a week) intratracheally. HDM-exposed mice showed an increase in airway hyper-responsiveness (AHR) and inflammation together with structural remodeling of the airways. We applied methylated DNA immunoprecipitation-next generation sequencing (MeDIP-seq) for profiling of DNA methylation changes in the lungs in response to HDM. We observed about 20 million reads by a single-run of massive parallel sequencing. We performed bioinformatics and pathway analysis on the raw sequencing data to identify differentially methylated candidate genes in HDM-exposed mice. Specifically, we have revealed that the transforming growth factor beta signaling pathway is epigenetically modulated by chronic exposure to HDM. Here, we demonstrated that a specific allergen may play a role in AHR through an epigenetic mechanism by disrupting the expression of genes in lungs that might be involved in airway inflammation and remodeling. Our findings provide new insights into the potential mechanisms by which environmental allergens induce allergic asthma and such insights may assist in the development of novel preventive and therapeutic options for this debilitative disease.
