Lung parenchyma changes in ankylosing spondylitis: demonstration with high resolution CT and correlation with disease duration.

OBJECTIVE To analyze the spectrum of the lung parenchyma changes in ankylosing spondylitis (AS) with high resolution computed tomography (HRCT) and correlate the findings with disease duration. MATERIAL AND METHODS Twenty patients (18 male, 2 female) with the diagnosis of AS according to New York criteria were included in the study. None of the patients had history of tuberculosis, prolonged inorganic dust exposure and hospitalization for pneumonia. Seven of the patients were smokers, three patients were ex-smokers, and 10 patients were nonsmokers. The patients were assigned to three groups depending on disease duration. Group 1: patients with disease duration <or=5 years (N: four patients), group 2: patients with disease duration >or=6 years but <or=10 years (N: four patients), group 3: patients with disease duration >or=11 years (N: 12 patients). HRCT and pulmonary function tests (PFT) were performed in all patients. RESULTS HRCT demonstrated pathology in 17 patients (85%). Two patients in group 1, 4 patients in group 2 and 11 patients in group 3 had pulmonary parenchyma changes. Emphysema (9/20), septal thickening (9/20) and pleural thickening (9/20) were the most common changes followed by nodule (8/20) and subpleural band formation (7/20). Three patients had apical fibrosis (AF). Septal and pleural thickening (both 4/10) were the most common changes when only nonsmokers were considered. Among nine patients with emphysema three were nonsmokers. CONCLUSION There is a wide spectrum in pulmonary parenchyma changes in AS. These changes begin in early stages of the disease and increase with disease duration. Although smoking complicates the spectrum of changes in pulmonary parenchyma, they are predominately in the form of interstitial inflammation.

Gait speed as a functional capacity indicator in patients with chronic obstructive pulmonary disease

AIM: Walking distance is generally accepted as a functional capacity determinant in chronic obstructive pulmonary disease (COPD). However, the use of gait speed in COPD patients has not been directly investigated. Thus, the aim of our study was to assess the use of gait speed as a functional capacity indicator in COPD patients. METHODS: A total 511 patients with mild-to-very severe COPD and 113 healthy controls were included. The lung functions (pulmonary function test), general health- and disease-related quality of life (Medical Outcomes Study 36-Item Short-Form of Health Survey, St Georges Respiratory Questionnaire), and gait speed (6-minute walk test) were assessed. RESULTS: The mean gait speed values were slower in moderate (75.7 ± 14.0 m/min), severe (64.3 ± 16.5 m/min), and very severe (60.2 ± 15.5 m/min) COPD patients than controls (81.3 ± 14.3 m/min). There were significant correlations between gait speed and age, dyspnea-leg fatigue severities, pulmonary function test results (FEV1, FVC, FVC%, FEV1/FVC ratio, PEF, PEF%), and all subscores of Medical Outcomes Study 36-Item Short-Form of Health Survey and activity, impact and total subscores of St Georges Respiratory Questionnaire in patients with moderate, severe, and very severe COPD. However, these correlations were higher especially in patients with severe and very severe COPD. CONCLUSIONS: As a conclusion, according to our results gait speed slows down with increasing COPD severity. Also, gait speed has correlations with age, clinical symptoms, pulmonary functions, and quality of life scores in COPD patients. Thus, we consider that gait speed might be used as a functional capacity indicator, especially for patients with severe and very severe COPD.

Sandblasting under Uncontrolled and Primitive Conditions in Turkey

Abrasive blasting involves forcefully projecting a stream of abrasive particles onto a surface, usually with compressed air or steam. Since silica sand is commonly used in this process, workers who perform abrasive blasting are often called sandblasters. A material with rough particles should be used in order to have a sufficient effect on resistant surfaces such as glass or metal. Mostly quartz (silicon dioxide=SiO 2 ) is forced by compressed air onto the target surface . Although the frequency of the procedure is declining, it is still applied in an uncontrolled fashion in small-scale workplaces (employing fewer than 10 workers). The application in narrow areas, the break up of the SiO 2 particles into smaller pieces when striking the surface and reuse of the same material, increase the respirable dust concentration and this leads to high risk of silicosis . In our country sandblasting is being done in smallscale workplaces, which would operate as contractors for bigger companies. The purpose of this procedure is to polish the surface of metal, which comes from foundries, and to make the glass dull. The structural features of all workplaces were similar to each other. Although they are in the framework of control mechanisms such as licensing procedures supervised by local public health centers and municipalities, data collection and occupational health & safety inspections and enforcements are not carried out effectively for smallscale companies, so that the actual magnitude of the occupational risks is not known. In view of these observations, this study was planned with the following aims: to evaluate the work environment and working conditions in small-scale sandblasting workplaces, and to detect the frequency of silicosis among these workers in Turkey.

Prognostic value of neutrophil-to-lymphocyte ratio in pulmonary arterial hypertension

Objective To evaluate the prognostic value of baseline neutrophil-to-lymphocyte ratio (NLR) in the prediction of long-term mortality in patients with pulmonary arterial hypertension (PAH). Methods This prospective study recorded NLR during initial diagnostic right-sided cardiac catheterization in adult patients with PAH. Demographic, clinical, laboratory and haemodynamic variables were compared by NLR tertile. Univariate and multivariate Cox regression analyses were used to determine whether NLR was independently associated with mortality. Results Adults with PAH (n = 101) were followed-up for mean ± SD 36.8 ± 23.6 months. The number of deaths, New York Heart Association functional capacity (NYHA FC), levels of brain natriuretic peptide (BNP) or C-reactive protein (CRP) and presence of pericardial effusion increased as the NLR tertile increased, but haemoglobin and tricuspid plane annular systolic excursion (TAPSE) decreased. On univariate analysis, high NLR values were associated with mortality, but on multivariate analysis, NLR did not remain an independent predictor of mortality. Baseline NYHA FC, TAPSE, BNP level and pericardial effusion were independent predictors of mortality. Conclusions NLR was correlated with important prognostic markers in PAH such as NYHA FC, BNP and TAPSE. This simple marker may be useful in the assessment of disease severity in patients with PAH.

Could “red cell distribution width” predict COPD severity?

BACKGROUND AND OBJECTIVES Erythrocyte morphology changes not only by primary hematological diseases but also by systemic inflammation, ineffective erythropoiesis and nutritional deficiencies. Red blood cell distribution width (RDW) is a parameter reflecting erythrocyte morphology. We aimed to investigate the relationship of RDW with chronic obstructive pulmonary disease (COPD) stages, BODE index and survival in COPD patients. METHODS Medical records of 385 COPD patients between July 2004 and November 2005 were studied retrospectively. Demographic features, BODE index factors and oxygen saturation were recorded. Survival analysis of all patients by 2014 was performed. Measured RDW values at the time of the inclusion were evaluated. RESULTS Mean age of the patients was 65.6±9.6 years. Distribution of the COPD stages of the patients were stage 1: 16%, stage 2: 52%, stage 3: 26%, stage 4: 6%. RDW was found significantly different between stages. The highest RDW was observed in the very severe stage (p<0.001). Median of BODE index was 1 (0-3). As the BODE index increased RDW also increased (p<0.001). When the patients were grouped according to the laboratory upper limit of RDW, survival rate was 31% in the RDW >14.3% group and 75% in the RDW <14.3% group. CONCLUSION The variability in the size of circulating erythrocytes increases as the COPD severity progresses. Therefore, a simple and noninvasive test, such as RDW, might be used as a biomarker in the evaluation of the severity of COPD. At the same time, there seems to be a correlation between the survival of COPD patients and RDW.

Penile lesion with inguinal adenopathy after intravesical Bacillus Calmette-Guerin instillation therapy

Intravesical Bacillus Calmette-Guérin (BCG) is widely used as an adjuvant therapy in the treatment of non-muscle-invasive bladder cancer. BCG is generally well tolerated, though localized and systemic infectious complications may occur. Infection of the glans and inguinal adenopathy are rare local complications of intravesical BCG therapy. Traumatic urethral catheterization is one of the main causes. We report the case of a 75-year-old male who developed granulomatous balanitis and enlarged inguinal lymph nodes after five cycles of intravesical BCG treatment for transitional cell carcinoma of the bladder. Histology revealed giant cell granuloma. Oral antituberculous treatment was initiated with subsequent full recovery of penile lesions and adenopathy. Physicians who administer BCG must be familiar with the possible complications and their adequate management and should inform patients about the side-effects accordingly.

Growth of a solitary pulmonary nodule after 6years diagnosed as oncocytic carcinoid tumour with a high 18-fluorodeoxyglucose (18F-FDG) uptake in positron emission tomography-computed tomography (PET-CT).

Introduction:  Pulmonary carcinoid tumour is low‐grade neuroendocrine malignancy that is seen 1%–2% of all lung neoplasms. Oncocytic carcinoid type is a rarely seen variant of pulmonary carcinoids. As carcinoid tumours have hypometabolic activity, they usually have lower 18‐fluorodeoxyglucose (18F‐FDG) uptake than expected for lung carcinoma on positron emission tomography (PET).

Tampa Scale of Kinesiophobia for Heart Turkish Version Study: cross-cultural adaptation, exploratory factor analysis, and reliability.

Purpose Individuals with cardiac problems avoid physical activity and exercise because they expect to feel shortness of breath, dizziness, or chest pain. Assessing kinesiophobia related to heart problems is important in terms of cardiac rehabilitation. The Tampa Scale of Kinesiophobia Swedish Version for the Heart (TSK-SV Heart) is reliable and has been validated for cardiac diseases in the Swedish population. The aim of this study was to investigate the reliability, parallel-form validity, and exploratory factor analysis of the TSK for the Heart Turkish Version (TSK Heart Turkish Version) for evaluating kinesiophobia in patients with heart failure and pulmonary arterial hypertension. Methods This cross-sectional study involved translation, back translation, and cross-cultural adaptation (localization). Forty-three pulmonary arterial hypertension and 32 heart failure patients were evaluated using the TSK Heart Turkish Version. The 17-item scale, originally composed for the Swedish population, has four factors: perceived danger for heart problem, avoidance of exercise, fear of injury, and dysfunctional self. Cronbach’s alpha (internal consistency) and exploratory factor analysis were used to assess the questionnaire’s reliability. Results of the patients in the 6-minute walk test, International Physical Activity Questionnaire, and Nottingham Health Profile were analyzed by Pearson’s correlation analysis with the TSK Heart Turkish Version to indicate the convergent validity. Results Cronbach’s alpha for the TSK Heart Turkish Version was 0.75, indicating acceptable internal consistency. Although exploratory factor analysis showed a different subgroup distribution than the original questionnaire, the model was acceptable for the four-factor model hypothesis. Therefore, the questionnaire was rated as reliable. Conclusion These results supported the reliability of the TSK Heart Turkish Version. Since the acceptable four-factor model fits the subgroups and measures of reliability are sufficiently high, the questionnaire seems reliable for pulmonary arterial hypertension and heart failure patients.

Cervical Mediastinoscopy Versus Computed Tomography for Detecting Enlarged Mediastinal Lymph Nodes in Non-Cancerous Lung Diseases

Cervical mediastinoscopy (CM) is considered to be the gold standard for evaluating mediastinal lymph nodes. The aim of this study was to determine the diagnostic yield of computed tomography (CT) and CM for detecting enlarged mediastinal lymph nodes in non-malignant pulmonary diseases. We retrospectively investigated the correlation and differentiation between chest CT and CM findings in terms of sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), in 30 patients with granulomatous lung disease diagnosed by CM and isolated enlarged lymph nodes seen on CT scans. Biopsy tissues from the lymph nodes in stations right, 1, 2, 3, 4, and 7, were obtained for pathological examination. The 30 patients comprised 11 men (mean age 47.1 ± 18.4 years) and 19 women (mean age 44.2 ± 14.0 years). Radiological examination showed that the diagnostic value of stations 2 and 4 was particularly high. Thus, when CM is used for diagnostic purposes, the small lymph nodes in station 1, obtained by careful dissection of the higher mediastinal region, can be helpful. Generally, there is no absolute consistency between the findings of CM and CT. For this reason, obtaining samples from each station regardless of CT findings is recommended.

Effect of disease severity on upper extremity muscle strength, exercise capacity, and activities of daily living in individuals with pulmonary arterial hypertension

OBJECTIVE Pulmonary arterial hypertension (PAH) is a rare disease. Although muscle strength, exercise capacity, quality of life, and activities of daily living of patients with PAH are affected, it is not known how they are affected by disease severity. The purpose of the present study was to investigate effects of disease severity on upper extremity muscle strength, exercise capacity, and performance of activities of daily living in patients with PAH. METHODS Twenty-five patients with disease severity classified according to the New York Heart Association (NYHA) as functional class II (n=14) or class III (n=11) were included in the study. Upper-extremity exercise capacity and limitations in performing activities of daily living were assessed with 6-minute pegboard and ring test (6PBRT) and the Milliken activities of daily living scale (MAS), respectively. Shoulder flexion, elbow extension, elbow flexion muscle strength, and handgrip strength were measured with dynamometer. RESULTS There were no significant differences in age, gender, body mass index, or mean pulmonary artery pressure between groups (p>0.05). The 6PBRT, MAS, and elbow flexion (right) and grip strength (right and left) results were significantly lower in NYHA III group than in NYHA II group (p=0.004, p=0.002, p=0.043, p=0.002 and p=0.003, respectively). There was no significant difference in shoulder flexion, elbow flexion (left), or elbow extension between groups (p>0.05). CONCLUSION Results suggest that upper extremity exercise capacity, elbow flexion muscle strength (right), and handgrip strength decrease and that limitations in activities of daily living grow as disease severity increases in patients with PAH. When planning rehabilitation programs, disease severity should be considered and evaluations and treatments for the upper extremities should be included.
