Can the ADO Index Be Used as a Predictor of Mortality from COVID-19 in Patients with COPD?

Background: Several studies have shown that the risk of mortality due to COVID-19 is high in patients with COPD. However, evidence on factors predicting mortality is limited.

Research Question: Are there any useful markers to predict mortality in COVID-19 patients with COPD?.

Chronic obstructive pulmonary disease phenotypes in Turkey: the COPET study-a national, multicenter cross-sectional observational study.

Background: While mortality rates decrease in many chronic diseases, it continues to increase in COPD. This situation has led to the need to develop new approaches such as phenotypes in the management of COPD. We aimed to investigate the distribution, characteristics and treatment preference of COPD phenotypes in Turkey.

Risk Factors for Mortality in Denim Sandblasters Silicosis: Selecting Candidate for Lung Transplantation.

Objective: This study aimed to review the risk factors for silicosis together with survival analysis and a perspective for lung transplantation with data from a single center.

Material And Methods: We reviewed the medical records of denim sandblasters who were referred to our center between January 2006 and December 2011 and evaluated 219 patients with a history of denim sandblasting with a minimum follow-up period of 5 years until 2016. We analyzed several personal and occupational features, together with functional and radiologic data.

Clinical importance of serum neopterin level in patients with pulmonary tuberculosis.

Objective: Neopterin is a sensitive marker for cell-mediated immune response. Because of this, the neopterin levels of body fluids show cell-mediated immune response in different infectious diseases which involve T cells and macrophages. The aim of this study was to determine the clinical importance of neopterin levels in patients with tuberculosis and compare with those levels of healthy subjects.

Pulmonary lymphangioleiomyomatosis: a rare case.

Lymphangioleiomyomatosis is an uncommon lung disease primarily affecting women of childbearing age. It is characterized by the progressive proliferation and infiltration of smooth muscle-like cells, which lead to cystic destruction of the lung parenchyma; obstruction of airways, blood vessels, and lymphatics; and loss of pulmonary function. We present the case of a 46-year-old female patient with chest pain, cough, sputum, and dyspnea on exertion for three weeks.

[Evaluation of Quantiferon-TB Gold and tuberculin skin test in patients with tuberculosis, close contact of patients, health care workers and tuberculosis laboratory personnel].

Tuberculin skin test (TST) has been used effectively for a long time, despite inherent sensitivity and specificity limitations. Patients with a positive TST without active tuberculosis are identified as having latent tuberculosis infection. Identifying patients with latent tuberculosis infection with this test is an important part of control of the disease.

Endobronchial cryobiopsy or forceps biopsy for lung cancer diagnosis.

Background: Invasive procedures such as bronchoscopic biopsy, bronchial washing, and bronchial brushing are widely used in diagnosis of lung cancers. The mean diagnostic rate with bronchoscopic forceps biopsy is 74% in central tumors. This study was designed to evaluate the efficacy of cryobiopsies in histopathological diagnosis.

Pulmonary hemosiderosis in association with celiac disease.

A 15-year-old male had a history of increasing dyspnea on exertion, cough, sputum production, fever, weakness, hemoptysis, and diarrhea. Chest radiography demonstrated bilateral alveolar consolidation. Bronchoalveolar lavage fluid analysis revealed extensive hemosiderin-laden alveolar macrophages.

An interesting cause of recurrent haemoptysis: haemoptysis 7 years after a foreign body penetrated the lung parenchyma and aorta.

A 43-year-old man presented with a 12-month history of recurrent haemoptysis. Postero-anterior chest X-ray of a patient with a history of a penetrating thoracic trauma 8 years previously showed a long wedge-shaped opacity just above the left hemidiaphragm, representing the 'tip of the knife' appearance, and penetrating from the lateral chest wall deep to the thoracic aorta. After consultation with the cardiovascular surgeons, it was decided that the patient should have an operation to remove the foreign body penetrating the aorta.
