Activity of Antioxidant Enzymes in the Tumor and Adjacent Noncancerous Tissues of Non-Small-Cell Lung Cancer.

Lung tissue is directly exposed to high oxygen pressure, as well as increased endogenous and exogenous oxidative stress. Reactive oxygen species (ROS) generated in these conditions play an important role in the initiation and promotion of neoplastic growth. In response to oxidative stress, the antioxidant activity increases and minimizes ROS-induced injury in experimental systems.

Identifying the Infection Control Areas Requiring Modifications in Thoracic Surgery Units: Results of a Two-Year Surveillance of Surgical Site Infections in Hospitals in Southern Poland.

Background: Surgical site infection (SSI) is considered to be a priority in infection control. The objective of this study is the analysis of results of active targeted surveillance conducted over a two-year period in the Department of Thoracic Surgery at the Pulmonology and Thoracic Surgery Center in Bystra, in southern Poland.

Patients And Methods: The retrospective analysis was carried out on the basis of results of active monitoring of SSI in the 45-bed Department of Thoracic Surgery at the Pulmonology and Thoracic Surgery Center in Bystra between April 1, 2014 and April 30, 2016.

Relationship between air pollution and metal levels in cancerous and non-cancerous lung tissues.

We aimed to check the relationships between levels of metals (Ca, Cd, Cu, Fe, Hg and Zn) in cancerous and non-cancerous lung tissues and their link to air pollution, expressed as particulate matter (PM) concentrations. The study also examines the influence on metal concentration in the lung tissue of patients' sex and the distance of their homes from the nearest emitter. We found that the general pattern of ascending concentrations in tumor tissue was as follows: Hg < Cd < Cu < Ca < Zn < Fe.

Can pancreatic tissue cause haemoptysis?

A mature teratoma is a tumour of primary germ cells. It is often found in the mediastinum. The authors describe a case of a young man who demonstrated haemoptysis as the only symptom of a mediastinal tumour.

Telomerase activity in non-small cell lung cancer.

Introduction: High telomerase activity has been detected in the majority of malignant neoplasms including lung cancer. The purpose of the study was to attempt to use telomerase activity as a prognostic factor in patients with non-small cell lung cancer (NSCLC).

Material And Methods: Telomerase activity was analyzed in 47 tissue specimens taken from patients with NSCLC.

Accumulation of metals in cancerous and healthy tissues of patients with lung cancer in Southern Poland.

The aim of this study was to investigate whether the concentrations of metals differ among patients with and without lung cancer with different smoking status and living in industrialized environments. We also evaluated the relationships between metals and blood parameters including hematocrit level (Hct), hemoglobin concentration (Hb), red (RBC) and white (WBC) blood cells numbers. Concentrations of metals were measured with AAS (copper - Cu, iron - Fe, magnesium - Mg, zinc - Zn) and CV-AAS (mercury - Hg).

[Granulomatous pneumonia as a complication of intravesical BCG immunotherapy--a case report].

BCG (Bacillus Calmette-Guerin) comprises an attenuated strain of Mycobacterium bovis and is used for vaccination against tuberculosis. An additional use of BCG is for immunotherapy of cancer in which the vaccine is administered intravesically for the treatment of superficial bladder cancer. The efficacy of immunotherapy with BCG in the prevention of recurrence is estimated at 70-99%, which is higher than for local chemotherapy.

[Diagnostic difficulties in diagnosis of Hodgkin's disease in a young man--a case report].

Unlabelled: Lymphomas are neoplasms of lymphocytes and their precursor cells. This disease develops from lymph nodes or extranodal lymphoid tissue. A common site for such a tumour is the chest.

[Is the vascular-endothelial growth factor responsible for the malignancy of lung cancer?].

Lung cancer is the most common malignancy in the world. Its large ability to regional extension of the tumor and formation of local and distant metastases causes that the number of deaths and cases of disease are almost identical. The reason of this ability lies in the creation process of blood vessels that is angiogenesis, which main stimulus is the vascular-endothelial growth factor (VEGF).

[Nodular lymphoid hyperplasia - a rare case of lymphoproliferative disorder of the lungs].

Nodular lymphoid hyperplasia (NLH) belongs to a very rare, mild, lymphoproliferative disease of unestablished aetiology historically included in the group of pseudolymphomas. Its existence was controversial for many years, until modern techniques of pathomorphological diagnosis approved it as a separate entity of lung disease. It manifests in the form of well limited nodules localized in the lungs, which are mostly identified accidentally.
