Evaluation of balance in patients with chronic obstructive pulmonary disease with practical tests.

INTRODUCTION: Patients with chronic obstructive pulmonary disease (COPD) have impaired balance and hence fall more frequently. Easy application of balance evaluation tests can prevent the loss of time in the outpatient clinic for patients with COPD. In this study, we aimed to compare the efficacy of Berg Balance Scale (BBS), a time-consuming but a widely used test, with other easy-to-perform tests such as the Single Leg Stance (SLS), Five Repetition Sit to Stand (5STS), Four Step Square (FSST), and Timed Up and Go (TUG) tests. METHODS: A total of 71 patients with COPD and 70 control subjects with matching demographic characteristics were included in the study. All patients undertook pulmonary function tests and their scores of 6-min walk-test (6MWT), modified Medical Research Council (mMRC) dyspnoea scale, COPD assessment questionnaire (CAT) and body mass index (B) were recorded. In addition, the severity of airway obstruction (O), the dyspnoea severity (D) and exercise capacity (E) (BODE) index scores were measured. All patients with COPD were classified into four groups, A to D, based on the GOLD 2017 criteria. All subjects undertook the BBS, SLS, 5STS, FSST and TUG tests. RESULTS: Balance tests revealed increased balance impairment in patients with COPD in comparison with the control subjects (P < .05). The BBS, SLS, FSST and TUG examinations suggested that balance impairment was frequent in Groups C and D patients with COPD (P < .05). FSST and TUG had the highest correlation with BBS (r = -.812 and -.842 and P < .001 and <.001, respectively). The results of FSST and TUG were the closest to those of BBS test. CONCLUSIONS: FSST and TUG tests can be applied for the assessment of bodily balance status among patients with COPD in outpatient clinics.

The evaluation of cardiac functions according to chronic obstructive pulmonary disease groups.

Objectives: We aimed to compare right and left ventricular functions by echocardiography (ECHO) according to chronic obstructive pulmonary disease (COPD) groups, and to determine their associations with functional parameters.Methods: Data of patients with COPD who underwent ECHO between 2015 and 2018 were analyzed retrospectively. The results of pulmonary function tests, 6-minute-walking test (6MWT), Modified Medical Research Council (mMRC), COPD assessment test (CAT), and BODE scores were recorded together with ECHO results showing right and left ventricular functions.Results: 126 COPD patients were evaluated. Of these, 37.3% was in group A, 28.6% in group B, 12.7% in group C, and 21.4% in group D. Most common comorbidities were cardiovascular diseases (CVD) and pulmonary hypertension (PH); these were most frequently seen in groups D and B. Regarding ECHO parameters, differences were present among groups in systolic pulmonary arterial pressure (sPAP) and left ventricle end-systolic diameter (LVEF) (p < 0.001 and 0.004, respectively). sPAP was highest in groups D and B whereas LVEF was lowest in group D.Conclusion: Our results suggest that patients' symptoms in symptomatic COPD groups B and D might be related to increased PAP and concomitant cardiovascular comorbidities. Therefore, a detailed cardiovascular investigation should be performed from early stages in COPD.

Laryngeal Tuberculosis Mimicking Laryngeal Carcinoma on 18F-FDG PET/CT Imaging.

Laryngeal tuberculosis is a rare presentation of tuberculosis. It can mimic laryngeal carcinoma with its clinical and imaging findings. A 51-year old woman underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) imaging for clinically suspected carcinoma of the larynx. PET/CT revealed lung lesions consistent with tuberculosis in additional to hypermetabolic focus on larynx. The patient was histopathologically diagnosed with lung and laryngeal tuberculosis.

Anthropometric methods in evaluation of chronic obstructive pulmonary disease.

Chronic Obstructive Pulmonary Disease (COPD) is mainly expressed by weight loss with especially fat-free mass (FFM) depletion and a low body weight correlates with increased mortality and a poor prognosis. We investigated whether anthropometric body composition equations could be used for evaluation of the body composition in COPD. Thirty clinically stable patients with COPD and 13 healthy age matched control subjects underwent the skinfolds and circumference measurements in addition to body mass index (BMI) calculations. Body fat mass (BFM) and FFM were determined by using anthropometric equations. The percent BFM, predicted from body density either using Siri's or Brozek's equations was determined lower than that of calculated with equations by using BMI, age and gender. The values of BFM and body weight were reduced in patients with FEV1 < % predicted compared to other participants. The FFM values also dropped depending on the severity of COPD. BMI was not statistically different among the participants while FFM index (FFMI) reflected the nutritional status of the disorders. Anthropometric equations easily and cost effectively applied for prediction of % BFM, FFM, and FFMI in patients with COPD. In addition, the FFMI can be possibly used for expressing COPD severity.
