Authors: Sliwiński P, Chazan R, Dąbrowiecki P, Jahnz-Różyk K, Mróz R, Pirożyński M Abstract Orally inhaled products delivered via inhalation exert their effect directly to the target organ. This allows to administer a very low dose of a drug compared with an oral route with similar clinical effect and significantly reduced toxicity. However inhalation therapy is also limited by several factors. Delivery of the desired dose of the drug to the airways depends on a type of the inhaler - pressurised metered-dose inhaler (pMDI) or dry powder inhaler (DPI), inhaler characteristics (low or high internal resistance, diameter of particles and distribution of the generated aerosol fine particles), thermal conditions of air, and ability of patient to generate sufficient inspiratory flo...

CONCLUSIONS: Pulmonary alveolar proteinosis is a rare interstitial disease with a mild course in most cases. In 13/17 patients diagnosis was based on histological examination of samples from open lung biopsy. The presented patients were observed in the years 1984-2004, and at that time histologic examination was the main diagnostic method. The most common abnormality in pulmonary function tests was decrease of DLCO. In most cases, spontaneous remission of the disease was observed. In four patients with severe course of PAP, WLL was performed with subjective, functional and radiological improvement in 3 of them.

[Current methods to detect EGFR gene mutations as predictive factor for targeted therapies in non-small cell lung cancer - is there a "golden standard" in diagnostics?]. Pneumonol Alergol Pol. 2014;82(3):311-22 Authors: Skroński M, Szpechciński A, Chorostowska-Wynimko J Abstract According to current Polish and international recommendations, detection of EGFR gene somatic mutations is the essential part of routine diagnostic algorithm in advanced NSCLC patients considered for tyrosine kinase inhibitor therapy. Molecular heterogeneity of tumor tissue and cytology materials used for molecular diagnostics is challenging for classic methods of genetic analysis, such as Sanger sequencing, driving the development and implementation of specialized, highly sensitive technique...

Authors: Domagała-Kulawik J, Osińska I Abstract Lung cancer is the main cause of cancer death worldwide. An advanced stage of the disease at the time of diagnosis, observed in the majority of cases, does not allow for introduction of radical treatment or makes the treatment ineffective. Lung cancer as a solid tumour with a very low antigenicity escapes immune surveillance, and cytotoxic cells attack. Cytotoxic lymphocytes play a key role in anticancer defence, but the population of these cells individually differs. Many suppressor and regulatory mechanisms inhibit the recognition of tumour antigens by dendritic and cytotoxic cell activation. The population of regulatory T cells (T regs) plays a crucial role in this inhibition of immune response. Their function depends on the expr...
