Arteriovenous malformations of the lung: diagnosis by thin-section HRCT and Cine-MRI

We report a case in which a solitary large and multiple group of small pulmonary arteriovenous malformations were demonstrated by computed tomography and magnetic resonance images that could aid diagnosis and therapeutic planning without the need for catheter angiography

CT and MRI appearance of a fistula between the right and left main bronchus caused by tracheobronchial tuberculosis

Tuberculosis of the trachea and main bronchi is a relatively rare disease seen predominantly in elderly patients. We present a case of a fistula between the right and left main bronchus owing to tuberculosis. We describe the CT and MRI appearances

Comparison of the Sit-to-Stand Test with 6 min walk test in patients with chronic obstructive pulmonary disease

Objective: To discuss the utility of Sit-to-Stand Test (STST) compared to the 6 min walking test (6MVY7) for the evaluation of functional status in patients with chronic obstructive pulmonary disease (COPD)

Association of macrophages, mast cells and eosinophil leukocytes with angiogenesis and tumor stage in non-small cell lung carcinomas (NSCLC).

The association between inflammatory cells, including tumor associated macrophage (TAM), mast cell (MC) and eosinophil Leucocyte (EL) densities and angiogenesis, as well as the relation of TAM, MC and EL densities and angiogenesis to tumor stage were investigated in specimens of 63 non-small cell lung carcinoma (NSCLC). Fifteen cases were in stage I, 12 were in stage II, 33 were in stage III and 3 were in stage IV. ELs and MCs were identified by hematoxilen-eosin and toluidine-blue histochemical stains, respectively. TAMs were shown by immunohistochemistry for CD68. Microvessets demonstrated by immunohistochemistry for CD31 were quantified by a stereotogical method and vascular surface density (VSD) and microvessel number (NVES) were calculated. There was not any statistically significant correlation between tumor's stage and VSD, TAM and EL counts. MC count and NVES were found to be higher, in early stages. VSD and NVES were not associated with EL, MC and TAM counts. The lack of consistent correlation of angiogenesis to the stage of disease in this study supports the view that tumor angiogenesis is not a significant prognostic factor in NSCLCs. The absence of correlation between MCs, ELs and TAM counts and angiogenesis and absence of any relation between ELs and TAMs and tumor stage are discordant with the results of some of the previous studies in NSCLCs and in other tumors. The differing results may be due to wide variations in methodologies which were used for demonstration of inflammatory cells and vessels and variations in the degree of activation and complexity of functions of these cells.

Chronic obstructive pulmonary disease group b and c: Are they really the opposite of each other regarding exercise capacity and muscle strength?

Purpose: "Combined COPD Assessment" in the classification of chronic obstructive pulmonary disease (COPD) was proposed as a new method by The Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD). The aim of this study was to evaluate exercise capacity, and muscle strength (respiratory and peripheral muscle strength) between two groups (Group B and C) of the new GOLD combined COPD assessment in this study. Methods: Patients were categorized into group B (n=18) and C (n=18) according to the GOLD combined COPD assessment. Patients' exercise capacity (the six-minute walk test [6MWT]) and the six-minute pegboard and ring test [6PBRT]), respiratory muscle strength (maximal inspiratory pressure [MIP] and maximal expiratory pressure [MEP]), and peripheral muscle strength (hand-grip and knee extensor strength) were assessed. Results: The MEP value was significantly higher in group B than in group C (p=0.024). Other values (6MWT distance, 6PBRT score, MIP values, and peripheral muscle strength) were not significantly different between the two groups (p>0.05). Conclusion: This study shows that comprehensive assessment is very important to evaluate patients with COPD. The GOLD spirometry measures are not solely enough, symptoms and exacerbation history must be evaluated. © 2018 Turkish Journal of Physiotherapy and Rehabilitation. All rights reserved
