The importance of biglycan, decorin and TGF-1 levels in the diagnosis of non-small cell lung cancer.

Background: Despite Non-small cell lung cancer (NSCLC) ranks among the most deadly cancers worldwide, and currently, apart from a low percentage, targetable molecules have not been identified in its etiopathogenesis. The relationship between the proteoglycans decorin and biglycan, which are present in the extracellular matrix of cells, and transforming growth factor Beta-1 (TGF-B1), has been shown in many cancers. We investigated the significance of these molecules in NSCLC.

The relationship of thiol/disulfide homeostasis in the etiology of patients with obstructive sleep apnea: a case-control study.

Aim: Obstructive sleep apnea syndrome (OSAS) is a chronic and incapacitating disease that often requires lifelong care. This study aimed to evaluate the thiol/disulfide homeostasis in patients with OSAS, to compare the thiol/disulfide levels with the control group and to investigate their relationship with the severity of the disease.

Material And Methods: Patients who were admitted to the department of chest diseases, and diagnosed with OSAS using polysomnographic analysis ( = 186) and 144 patients who underwent polysomnography due to some reasons but ruled out of having OSAS were included in the study.

The prognostic and predictive significance of serum thiols and disulfide levels in advanced non-small cell lung cancer.

Serum Total Thiol (TT), Native Thiol (NT), and Disulfide (SS) levels were found significantly lower in benign proliferative pathologies and cancer disease compared to healthy subjects. We conducted this prospective study to investigate the possible predictive and prognostic significance of these markers in non-small cell lung cancer (NSCLC), which is one of the most associated cancers with oxidative stress. This was a non-randomized, prospective, and case-control study of 120 subjects, including 60 patients with metastatic or inoperable NSCLC at the time of diagnosis and 60 demographically-matched controls.

Fibulins: a new biomarker for pulmonary thromboembolism?

Objectives: Fibulin-1, -2, -4, and -5 have important role in several vascular diseases. We aimed to investigate if fibulin-4 and -5 can be used as a biomarker for pulmonary thromboembolism (PTE).

Methods: This is a prospective case control study.

General features of patients with Pulmonary Langerhans Cell Histiocytosis followed in our instution.

Introduction: Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare disease affecting young smokers. It is more common between the ages of 20-40 and equals the male/female ratio. Lung biopsy is the most useful methods for diagnosis.

Efficacy and safety of endobronchial ultrasound-guided transbronchial needle aspiration through the pulmonary arteries for the diagnosis of left hilar lesions.

Introduction: Endobronchial ultrasonography (EBUS) is an endoscopic method that aids needle aspiration to see the bronchial wall and adjacent tissues with an ultrasound probe. Pulmonary arteries are rarely present between the bronchus wall and the tissue. In this case, it was necessary to make a selection between invasive processes and transbronchial needle aspiration (TBNA) through the pulmonary artery.

A Rare Cause of Hemoptysis in Childhood: Tracheal Capillary Hemangioma.

Hemangiomas are benign tumors most frequently seen in childhood and are mostly associated with cutaneous and mucosal surfaces. Tracheal capillary hemangiomas are extremely rare. The most common presenting symptom is hemoptysis, ranging from minor to major and chronic cough.

High serum levels of IGF-I and IGFBP3 may increase comorbidity risk for asthmatic patients.

Objective: Asthma is known as a chronic inflammatory lung disease which has also systemic features. Insulin-like growth factor I (IGF-I) plays a role for asthma pathogenesis. Controversially, IGF-binding protein 3 (IGFBP3) blocks asthma development.

Retrospective review of epidemic viral pneumonia cases in Turkey: A multicenter study.

Influenza A (H1N1) caused its first pandemic in 2009 in USA and Mexico. Since then, clinicians have exercised great care in order to make an early diagnosis of viral pneumonias. This is due in part to pandemic influenza A infection having greater impact on populations <65 years old than other viral strains, including seasonal influenza.

Moxifloxacin related thrombocytopeniae: A case report.

Drug-induced thrombocytopenia can be caused by various medications, most frequently, antibiotics. There have been reports of thrombocytopenia cases due to the usage of quinolone antibiotics, although moxifloxacin-related thrombocytopenia has been reported very rarely. The case is here presented of a 60-year old male with chronic obstructive pulmonary disease who presented with complaints of progressively worsening dyspnea.

Comparison of the Fractional Exhaled Nitric Oxide Levels in Adolescents at Three Schools Located Three Different Distances from a Large Steel Mill.

Exposure to ambient metals and air pollutants in urban environments has been associated with impaired lung health and inflammation in the lungs. Fractional exhaled nitric oxide (FeNO) is a reliable marker of airway inflammation. In this study, we aimed to compare the FeNO levels of three schools that have different distances from iron and steel industry zone for assessing the effects of heavy metals and air pollution on their respiratory health.

Assessment of Palliative Care in Lung Cancer in Turkey.

Objective: To investigate the symptoms of lung cancer in Turkey and to evaluate approaches to alleviate these symptoms.

Tracheobronchial Amyloidosis Mimicking Tracheal Tumor.

Tracheobronchial amyloidosis is a rare presentation and accounts for about 1% of benign tumors in this area. The diagnosis of disease is delayed due to nonspecific pulmonary symptoms. Therapeutic approaches are required to control progressive pulmonary symptoms for most of the patients.

Evaluation of multidrug resistance-1 gene C>T polymorphism frequency in patients with asthma.

Objectives: Asthma is a chronic inflammatory lung disease characterized by bronchial hyperresponsiveness and airflow obstruction. Genetic and oxidative stress factors, in addition to pulmonary and systemic inflammatory processes, play a pivotal role in the pathogenesis of asthma. The products of the multidrug resistance-1 gene protect lung tissue from oxidative stress.

Diagnosis of Pulmonary Hydatid Cyst by Bronchoscopy.

Hydatid cyst is a parasitic infestation caused by Echinococcus granulosus. Lungs are the second most common site of involvement after liver. The diagnosis of complicated pulmonary hydatid cysts may not be easy because hydatid cyst disease mimics tuberculosis, lung cancer, empyema, or abscess.

Visfatin and ghrelin: can they be forthcoming biomarkers or new drug targets for asthma?

Background & Aim: Asthma represents chronic inflammation of the airways and is associated with bronchial hyperresponsiveness and reversible airway obstruction. A novel adipokine visfatin and an appetite-modulating hormone ghrelin play a role in several diseases related with inflammation. Although visfatin is a pro-inflammatory adipokine, ghrelin mainly exerts anti-inflammatory effects.

Association of Fragmented QRS with Subclinical Left Ventricular Dysfunction in Patients with Obstructive Sleep Apnea.

Objective: We aimed to investigate whether fragmented QRS (fQRS) is associated with subclinical left ventricular (LV) dysfunction in patients with obstructive sleep apnea (OSA).

Subjects And Methods: A total of 141 patients with OSA who had normal LV ejection fraction (LVEF) were included in the study. The fQRS was defined as the presence of an additional R wave, notching of R or S wave or the presence of fragmentation in 2 contiguous electrocardiography (ECG) leads.

False-positive 18-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) scans mimicking malignancies.

Aim: 18-Fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) is an imaging modality that is often used to help differentiate benign from malignant pulmonary lesions and it has been shown to be more efficacious than conventional chest computed tomography (CT). However, some benign lesions may also show increased metabolic activity which can lead to false-positive PET findings. We aim to illustrate false positive findings of PET scan that simulate lung cancer in a variety of diseases.

Pulmonary Cement Embolism following Percutaneous Vertebroplasty.

Percutaneous vertebroplasty is a minimal invasive procedure that is applied for the treatment of osteoporotic vertebral fractures. During vertebroplasty, the leakage of bone cement outside the vertebral body leads to pulmonary cement embolism, which is a serious complication of this procedure. Here we report a 48-year-old man who was admitted to our hospital with dyspnea after percutaneous vertebroplasty and diagnosed as pulmonary cement embolism.

An unusual case of pulmonary nocardiosis in immunocompetent patient.

Pulmonary nocardiosis is a subacute or chronic necrotizing pneumonia caused by aerobic actinomycetes of the genus Nocardia and rare in immune-competent patients. A 35-year-old male, who had treated with antituberculosis drugs, presented with cough, dyspnea, and expectoration with episodes of hemoptysis with purulent sputum. The diagnosis of nocardiosis was made by microscopic examination of the surgically resected portion of the lung and revealed filamentous Gram-positive bacteria.
