Aim And Introduction: Diagnosing of interstitial lung disease (ILD) is difficult and expensive. The standard diagnostical approaches to ILD are bronchoalveolar lavage, transbronchial lung biopsy, transbronchial lung cryobiopsy (TBLC) and surgical lung biopsy (SLB). SLB is gold standard for the confident diagnosis of ILD but because of the poor performance of the patients it's use is limited.

Understanding the frequency and risk factors related to readmission can provide valuable input for the development of readmission reduction strategies. The aim of this study was to investigate the frequency, specific risk factors and the cost analysis of early readmission for any reason within 30 days after discharge of the patients hospitalized for acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

Material And Methods: In this retrospective comparative case series study, a total of 132 patients, who had been diagnosed with adult, culture-positive, active pulmonary TB were reviewed. The FQ group had 30 patients who had had ≥1 time and ≥7 days of FQ exposure within 1 year before the diagnoses.
Background/aim: Diagnosis of interstitial lung diseases requires a multidisciplinary approach, and a gold standard for histological diagnosis is open lung biopsy. Transbronchial lung biopsy (TBLB) and in recent years an alternative method, cryobiopsy (TBLC), are used for the diagnosis of parenchymal lung lesions. The aim of this study is to compare the efficacy of concomitant conventional TBLB and TBLC.
View Article and Find Full Text PDFBackground: Sarcoidosis and Mediastinal Tuberculous Lymphadenitis (MTLA) are two granulomatous diseases. Differentiation between these two diseases is dependent on clinical presentation, microbiological investigation, and cytopathological examination. In endemic regions, differential diagnosis of MTLA and sarcoidosis might be difficult.

It is often difficult to diagnose tuberculosis in patients with lymphadenopathy without parenchymal lesions. The aim of this study was to describe the diagnostic utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in patients with isolated mediastinal tuberculous lymphadenitis (MTLA).

The reaction proceeds via metal salt free, in-situ formation of asymmetric azine followed by cyclization to provide 1,2,3-triazole 1-oxide compound. It has been structurally characterized.

Endobronchial ultrasound (EBUS) is a technique for the detection of mediastinal abnormalities. A total of 548 EBUS procedures were performed for various indications, and in four cases (0.7%), filling defects in central pulmonary arteries were demonstrated fortuitously during the procedure.

Materials And Methods: Between March 2011 and August 2013, 378 EBUS-TBNA procedures were performed. Sixty-three (16.
Aim: We aimed to assess the platelet-to-lymphocyte ratio (PLR) and platelet parameters in patients with chronic obstructive pulmonary disease (COPD).
Methods: A total of 60 stable COPD patients, 50 acute exacerbation COPD patients and 50 healthy controls were enrolled in this study.
Results: The platelet distribution width and PLR were higher and the mean platelet volume was lower in the COPD patients during acute exacerbation compared with the stable patients and controls.
Aim: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a safe and minimally invasive procedure that can be performed in outpatient settings. Several studies have demonstrated the usefulness of EBUS-TBNA in the diagnosis of sarcoidosis and malignant diseases. This study focused on the role of cell block (CB) analysis in determining the diagnostic yield of EBUS-TBNA in malignant diseases and sarcoidosis.

Aim: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), which enables cytological examination of mediastinal lymph node (LN) aspiration samples, is a safe and minimally invasive method for diagnosis and staging of lung cancer and diagnosis of diseases affecting mediastinal LNs. In this study, we investigated the yield of EBUS-TBNA for diagnosis of lymphoma and reviewed the literature since the British Thoracic Society (BTS) guidelines were published.
Materials And Methods: We retrospectively evaluated our database for patients who underwent EBUS between March 2011 and December 2014.
In this study, Mycobacterium tuberculosis complex was detected by BD ProbeTec ET system in 4716 respiratory and 167 nonrespiratory samples [mostly (98%) smear negative). Sensitivity, specificity, positive and negative predictive values were 81.8%, 98.

The aim of the study was to determine the prognostic factors affecting survival in patients with malignant pleural mesothelioma.
Study Design: One hundred and twenty-five patients who had been diagnosed histologically as having malignant pleural mesothelioma over the past 5 years were evaluated retrospectively.
Tuberculosis is treated with a group of drugs that need to be used over a long period of time and isoniazid is the major drug in this group. Antituberculosis drug-induced hepatitis is the most serious problem in tuberculosis treatment. The enzyme N-acetyltransferase-2 (NAT-2) metabolizes isoniazid in the liver so it is considered to cause hepatotoxicity.

Objectives: The aim of this study was to investigate if assisted pressure-controlled ventilation (APCV) can be a better alternative to pressure-support ventilation (PSV) for NIV in COPD patients with acute hypercapnic respiratory failure (AHRF).
Methods: In this prospective randomized study, we evaluated the early effects of noninvasive APCV and PSV in 34 consecutive COPD patients with AHRF.
A 61-year-old woman presented with an eosinophilic pleural effusion, secondary to transdiaphragmatic intrapleural spread of an hepatic hydatid cyst. Right posterolateral thoracotomy and frenotomy revealed a loculated pleural effusion associated with a 10 x 8 cm hydatid cyst in the posterior segment of the liver. Hydatid disease should be included in the differential diagnosis of eosinophilic pleural effusions in endemic regions.

In the present study, the diagnostic value of 16-kDa and 38-kDa mycobacterial antigens was investigated in patients who were diagnosed with tuberculosis by clinical and/or bacteriological findings in Turkey. The PATHOZYME-TB Complex Plus commercial ELISA kit was used for measuring immunoglobulin G against 38-kDa and 16-kDa recombinant antigens.
