Factors affecting voice quality in early glottic cancer before and after radiotherapy

score above 18 was considered characteristic for a clinical voice disorder. 13 In order to evaluate the post-radiation mucosal changes (tissue defects, atrophy, fibrosis, oedema; graded from 0 to 3 [0 = no changes, 3 = severe changes]), closure between the vocal folds (complete, incomplete), and the mobility of the vocal folds (normal, impaired, immobile), a stroboscopy was performed 3 months after the RT. Objective acoustic analysis of voice samples and aerodynamic measurement An acoustic analysis of three samples of the vowel /a/ at the most comfortable

Reply to comments on “State of the art in magnetic resonance imaging of hepatocellular carcinoma”: the role of DWI

the evaluation of treatment response to systemic and locoregional therapies in hepatic malignancies. DWI is an MRI sequence which provides useful information especially in the absence of intravenous contrast media. 3 In this context, the intravoxel incoherent motion (IVIM) model is based on the fact that perfusion exists inherently in DWI voxels and influences the measurement of the apparent diffusion coefficient (ADC), allowing qualitative and quantitative assessment. It can be used in the differentiation between benign and malignant hepatic nodule, such as

Health-related quality of life in Croatian general population and multiple myeloma patients assessed by the EORTC QLQ-C30 and EORTC QLQ-MY20 questionnaires

on comparable and standardized measures and that can be used to improve the health care system. Conducting studies using various health-related quality of life measures is a basis for improvement of health care delivery. 6 In the last decades, the measurement of health-related quality of life has gained acceptance as a primary or secondary endpoint in cancer research worldwide. 7 Evaluation of quality of life is conducted by using standardized questionnaires. 8 European Organization for Research and Treatment of Cancer (EORTC) has purposed a development of an

Local recurrence of soft tissue sarcoma: a radiomic analysis

estimated: for research purposes Cronbach’s alpha was considered acceptable if between 0.7 and 0.8. 13 Results Intra-observer agreement resulted to be 0.62 (95% CI: 0.52–0.67) for single measurements and 0.75 (95% CI: 0.69–0.80) for the average measure and was deemed acceptable for the purpose of the study. There were no discrepancies higher that 15% between R1 ROI and R2 ROI requesting arbitration. N = 11 adult patients (6 men and 5 women) with suspicious STS LR were included for a total of 33 follow-up events on MRI. A total of 198 data-sets per patients of both

Transcription factors gene expression in chronic rhinosinusitis with and without nasal polyps

performed on ABI PRISM 7500 Fast Real-Time PCR System at standard conditions utilizing TaqMan Fast Advanced Master Mix (Applied Biosystems). The Taqman assays T-bet ( TBX21) (Hs00203436_m1) , GATA3 (Hs00231122_m1), RORC (Hs01076122_m1) and FOXP3 (Hs00203958_m1) were utilized to determine the mRNA expression levels of transcription factors and glyceraldehyde-3-phosphate dehydrogenase (GAPDH; 4333764F) as an endogenous control (all Applied Biosystems). All measurements were performed in triplicate for each sample and relative expression was analyzed using the ΔΔCt

The “question-mark” MR anatomy of the cervico-thoracic ganglia complex: can it help to avoid mistaking it for a malignant lesion on 68Ga-PSMA-11 PET/MR?

), but smaller than 8 mm reported by Jamieson et al . 2 The other diameters also differed in comparison with cadaver studies, the length was shorter, which was most probably caused by the different character of the study method: section – and imaging, and possibly because of different measurement policies and the measurement plane. Similarly, Hogan and Erickson 11 in MR study reported obtaining smaller cephalocaudal SG dimension than in previous dissection studies, of just over 1cm, which corresponded to our results of about 13 mm. In our MR-based study mean SUV
