Evaluation of nutritional parameters that may be associated with survival in patients with locally advanced non-small cell lung carcinoma receiving definitive concurrent chemoradiotherapy: retrospective study conducted in a tertiary pulmonary hospital.

Sarcopenia, defined as skeletal muscle loss, is thought to be a hallmark of cancer cachexia. It has an impact on mortality, especially in cancer patients. There are also opposing views regarding the relationship between definitive concurrent chemoradiotherapy (CRT) and sarcopenia in locally advanced lung cancer.

Ipsilateral lung dose as a correlative measure for radiation pneumonitis in patients treated with definitive concurrent radiochemotherapy.

Objective: Mean lung dose (MLD) and percent of total lung (TL) volume that receive a dose greater than 20 Gy (V) have been the most validated parameters in the prediction of radiation pneumonitis (RP). However, these parameters present mean values of TL parenchyma and predict the right and the left lung as a unique functional organ unit, not take into account the difference in function and dose density between the lungs. Furthermore, there have been very limited data evaluating ipsilateral lung dosimetric constraints in addition to TL parameters to predict RP in non-small cell lung cancer (NSCLC) patients treated with radiochemotherapy (RCT).

Pitfalls in the surgical treatment of undiagnosed lung lesions and cystic pulmonary hydatidosis.

Background: Hydatid cysts can mimic many lung pathologies radiologically, as well as some malignant or benign lung tumors may show hydatid cyst-like radiological features. The aim of our study is to present our clinical experience and recommendations by analyzing the cases that create diagnostic difficulties by presenting a common radiological pattern with a pulmonary hydatid cyst.

Methods: The patients who were operated on with a preliminary diagnosis of hydatid cyst but were diagnosed differently, and who were operated on with different prediagnoses and unexpectedly diagnosed with hydatid cyst were included in the study.

Comparison of Brock University, Mayo Clinic and Herder models for pretest probability of cancer in solid pulmonary nodules.

Objective: Risk analysis models, which are used in the diagnostic algorithm of incidental pulmonary nodules, are based on patient data from developed countries. Mayo Clinic, Brock University and Herder are among the most known models. We aim to compare the reliability of these models in patients with indeterminate solid nodules and to investigate the contribution of the predictors used to the model.

Factors Affecting the Risk of Interstitial Lung Disease Development in Hospitalized Patients With COVID-19 Pneumonia.

Background: Coronavirus disease 2019 (COVID-19) related chronic lung changes secondary to severe disease have become well known. The aim of this study was to determine the risk factors that affect the development of interstitial lung disease in subjects with COVID-19 pneumonia who were hospitalized.

Methods: Patients hospitalized with COVID-19 pneumonia between June 2020 and March 2021 were retrospectively analyzed.

Correlation between chest CT severity scores and clinical and biochemical parameters of COVID-19 pneumonia.

Background: The COVID-19 pandemic, which first appeared in Wuhan, China, in December 2019 and spread rapidly around the globe, continues to be a serious threat today. Rapid and accurate diagnostic methods are needed to identify, isolate and treat patients as soon as possible because of the rapid contagion of COVID-19. In the present study, the relation of the semi-quantitative scoring method with computed tomography in the diagnosis of COVID-19 in determining the severity of the disease with clinical and laboratory parameters and survival of the patients were investigated along with its value in prognostic prediction.

FDG PET/CT signs of proven pulmonary hydatid cyst: is there any clue?

Purpose: Pulmonary hydatid cyst (PHC) can imitate many diseases. Sometimes, positron emission tomography/computed tomography (PET/CT) is performed in terms of malignancy exclusion for complicated cysts. Although some specific findings (doughnut sign) have been identified in hydatid cyst of the liver, there is no specific sign described for PHC.

Comparison of typical and atypical computed tomography patterns regarding reversibility and fibrosis in pulmonary sarcoidosis.

Purpose: This study aims to investigate whether there is a significant difference between typical and atypical parenchymal patterns in the development of fibrosis, which is the most crucial factor affecting morbidity in pulmonary sarcoidosis.

Methods: In our hospital, 145 cases with Siltzbach Types 2 and 3 sarcoidoses diagnosed by clinical, radiological, and histopathologic were retrospectively investigated. Perilymphatic nodules, accompanying mosaic attenuation, and interlobular septal thickening and central peribronchovascular bunch-like thickening on high-resolution computed tomography were assessed as typical.

Effect of Rebound Thymic Hyperplasia on Survival in Chemotherapy-Treated Lung Cancer.

Objectives: Thymus is a lymphoepithelial system in which cells responsible for the immune system are produced and directed. The aim of this study is to determine the overall survival effect of rebound thymic hyperplasia (RTH) in patients with non-small cell lung cancer (NSCLC) treated with systemic chemotherapy (CT).

Materials And Methods: The study was designed as retrospective case series.

A promising tool for T-staging of lung cancer: Is convex probe endobronchial ultrasound superior to computed tomography in detecting invasion of mediastinal and hilar vessels?

Background: In the present study, we aimed to compare performance of convex probe endobronchial ultrasound and computed tomography in detecting vascular invasion of mediastinal and hilar lesions.

Methods: Medical data of a total of 55 patients (47 males, 8 females; mean age 59.6±7.

The effect of the presence and severity of bronchiectasis on the respiratory functions, exercise capacity, dyspnea perception, and quality of life in patients with chronic obstructive pulmonary disease.

Background: Bronchiectasis is common in patients with advanced chronic obstructive pulmonary disease (COPD) and adversely affects the patients' clinical condition. This study aimed to investigate the effects of bronchiectasis on exercise capacity, dyspnea perception, disease-specific quality of life, and psychological status in patients with COPD and determine the extent of these adverse effects by the severity of bronchiectasis.

Methods: A total of 387 COPD patients (245 patients with only COPD [Group 1] and 142 COPD patients with accompanying bronchiectasis [Group 2]) were included in the study.

Diagnostic success of transthoracic needle biopsy and PET-CT for 1 to 2 cm solid indeterminate pulmonary nodules.

Objectives: Among the nodule types, the most controversial group are indeterminate solid nodules from 1 to 2 cm in size with the first choice being transthoracic needle biopsy (TTNB) or positron emission tomography (PET-CT) or both methods together. However, no single diagnostic algorithm could be applied to all cases. This research discusses the diagnostic success of PET-CT and TTNB.

A new perspective for pulmonary thromboembolism radiology: 'Pulmonary vein sign'.

Introduction: Pulmonary thromboembolism (PTE) is a clinical condition that can result in sudden death. Computed tomography pulmonary angiography (CTPA) is the most sensitive imaging technique for the diagnosis of PTE. Filling defects in the pulmonary veins, which can be identified in areas adjacent to PTE, have been named the 'pulmonary vein sign' (PVS).

Prolonged air leakage in secondary spontaneous pneumothorax: is proportion of emphysema important?

Introduction: Prolonged air leakage is the most common complication that can cause severe problems in cases of secondary spontaneous pneumothorax (SSP). The purpose of this study was to explore whether Goddard Classification Score (GCS) can be a marker of prolonged air leakage, particularly during the post-operative period, for patients with emphysema.

Methods: Fifty patients, who underwent tube thoracostomy for SSP, were retrospectively evaluated.
