RESUMEN
OBJECTIVE: To evaluate the use of a computer-based biodex balance exercise system (BBS) on balance, neuropathic pain, clinical presentation and nerve function in patients with diabetic peripheral neuropathy (DPN). METHODS: A total of 32 participants with DPN were randomly assigned in a 1:1 ratio to an intervention group (IG) or control group (CG). The IG performed exercises using the BBS twice weekly for 8 weeks, while CG were informed regarding diabetes self-management. At baseline and after study completion, participants underwent balance (postural stability and fall risk) and neuropathic pain assessment (DN4 questionnaire) and were screened using the Michigan Neuropathy Screening Instrument and nerve conduction test. RESULTS: Among the baseline participants, 14 in the IG and 13 in the CG completed the study. Balance training improved postural stability (overall, p<0.001), fall risk (p<0.001), neuropathic pain (p=0.01) and symptoms (p<0.001), and clinical presentation (p=0.02), but not nerve function, within the IG. At follow-up, IG displayed significantly improved stability (p<0.001) and fall risk (p=0.02) and decreased neuropathic symptoms (p=0.01) compared to the CG. CONCLUSION: Computer-based balance exercises improve balance, pain, and clinical presentation of DPN, but not nerve function, in patients with DPN. CLINICALTRIALS: gov ID: NCT05255497.

OBJECTIVE: Pleural effusion is a common medical problem. It is important to decide whether the pleural fluid is a transudate or an exudate. This study aims to measure the attenuation values of pleural effusions on thorax computed tomography and to investigate the efficacy of this measurement in the diagnostic separation of transudates and exudates. MATERIALS AND METHODS: 380 cases who underwent thoracentesis and thorax computed tomography with pleural effusion were classified as exudates or transudates based on Light's criteria. Attenuation measurements in Hounsfield units were performed through the examination of thorax computed tomography images. RESULTS: 380 patients were enrolled (39 % women), the mean age was 69.9 ± 15.2 years. 125 (33 %) were transudates whereas 255 (67 %) were exudates. The attenuation values of exudates were significantly higher than transudates (15.1 ± 5.1 and 5.0 ± 3.4) (p < 0.001). When the attenuation cut-off was set at ≥ 10 HU, exudates were differentiated from transudates at high efficiency (sensitivity is 89.7 %, specificity is 94.4 %, PPV is 97 %, NPV is 81.9 %). When the cut-off value was accepted as < 6 HU, transudates were differentiated from exudates with 97.2 % specificity. CONCLUSION: The attenuation measurements of pleural fluids can be considered as an efficacious way of differentiating exudative and transudative pleural effusions.

SUMMARY OBJECTIVE: In coronary computed tomography angiography, a part of the lung parenchyma also enters the image area which is called the field of view. The aim of this study was to evaluate the rate of pulmonary abnormalities and document their association with demographic features in subjects undergoing multislice coronary computed tomography angiography obtained for the assessment of coronary artery disease. METHODS: This was a retrospective observational study evaluating the coronary computed tomography angiography scans of 1,050 patients (58.5% males and 47.3% smokers) with a mean age of 52.2±11.2 years, obtained between January 2018 and March 2020. Pulmonary abnormalities were reported as nodules, focal consolidations, ground-glass opacities, consolidations, emphysema, cysts, bronchiectasis, atelectasis, and miscellaneous. RESULTS: In total, 274 pulmonary abnormalities were detected in 266 patients (25.3%). The distribution of incidental lung findings was as follows: pulmonary nodules: 36.4%, emphysema: 15.6%, bronchiectasis: 11%, ground-glass opacities: 7.2%, atelectasis 7.2%, focal consolidations: 5%, cysts: 6%, consolidations: 2.5%, and miscellaneous: 9.1%. The patients with pulmonary pathology were older (55.5±11.4 versus 51.0±10.9 years), and the percentage of smokers was higher (60.1 versus 43.2%). The possibility of the presence of any incidental lung findings in field of view of coronary computed tomography angiography increases significantly over the age of 40.5 years (p<0.001, AUC 0.612, 95%CI 0.573-0.651). CONCLUSION: Multislice coronary computed tomography angiography can give important clues regarding pulmonary diseases. It is essential for the reporting radiologist to review the entire scan for pulmonary pathological findings especially in patients with smoking history and over the age of 40.5 years.
