RESUMO
BACKGROUND: Vocal disorders are frequent in people with multiple sclerosis (MS). Cognitive impairment, fatigue, depression, and other clinical characteristics can be associated with treatment effectiveness in rehabilitation. Finding baseline characteristics that identify those who are responding to treatment can help the clinical decision-making process, which can then help improve the effectiveness of voice treatment. We developed a model to identify factors associated with treatment-related improvement on voice intensity in people with MS. METHODS: Data are from a randomized controlled trial of the effects of voice therapy. Forty-four people with MS were enrolled and randomized to receive Lee Silverman Voice Treatment LOUD, specifically addressing voice intensity, or conventional speech-therapy group. Voice intensity (dB) was measured during monologue before and after treatment and was used to differentiate those who responded (posttreatment voice intensity > 60 dB) from those who did not. Possible associated factors were cognitive impairment, fatigue, depression, disability, and disease duration. Associations were assessed by univariate logistic regression and univariate and multivariate linear regressions. RESULTS: Mean ± SD monologue voice intensity is improved in the whole sample (before rehabilitation: 51.8 ± 4.2 dB; and after rehabilitation 57.0 ± 6.5 dB; P < .001), and 11 people with MS (27.5%) responded to treatment. Specificity of treatment was associated with the return to normal voice intensity (OR, 14.28; 95% CI, 12.17-309.56) and we found a linear association between voice improvement and the specificity of treatment (6.65 [SE = 1.54] dB; P < .05). Moreover, the analysis revealed a nonlinear association between improvement and fatigue, suggesting increased benefits for people with MS with moderate fatigue. Other factors were not significantly associated with treatment effectiveness. CONCLUSIONS: Moderate fatigue and the specificity of the intervention seem to be key factors associated with clinically relevant improvement in voice intensity even in people with MS with a high level of disability and long disease duration.
RESUMO
We evaluated tumor response at Computed Tomography (CT) according to three radiologic criteria: RECIST 1.1, CHOI and tumor volume in 34 patients with metastatic adrenocortical carcinoma (ACC) submitted to standard chemotherapy. These three criteria agreed in defining partial response, stable or progressive disease in 24 patients (70.5%). Partial response (PR) was observed in 29.4%, 29.4% and 41.2% of patients according to RECIST 1.1, CHOI and tumor volume, respectively. It was associated with a favorable prognosis, regardless of the criterion adopted. The concordance of all the 3 criteria in defining the disease response identified 8 patients (23.5%) which displayed a very good prognosis: median progression free survival (PFS) and overall survival (OS) 14.9 and 37.7 months, respectively. Seven patients (20.6%) with PR assessed by one or two criteria, however, still had a better prognosis than non-responding patients, both in terms of PFS: median 12.3 versus 9.9 months and OS: 21 versus 12.2, respectively. In conclusions, the CT assessment of disease response of ACC patients to chemotherapy with 3 different criteria is feasible and allows the identification of a patient subset with a more favorable outcome. PR with at least one criterion can be useful to early identify patients that deserve continuing the therapy.
RESUMO
Anatomic variants in the head and neck are quite numerous and occur frequently: a minority of them increase the risk of complications during surgical procedures and may be visualized on cross-sectional images. As some of these complications are potentially fatal, awareness (and accurate reporting) of such variants is a basic responsibility of radiologists, particularly when surgery in the pertinent anatomic area is under consideration.
RESUMO
BACKGROUND: Despite the popularity of less invasive approaches for conduits procurement in coronary artery bypass graft surgery, concerns have been raised about the potential detrimental effects of the endoscopic technique when compared with the conventional "open" technique. METHODS: Among 470 patients undergoing coronary surgery with the use of a radial artery conduit, a propensity score analysis was performed among those patients assigned either to an open technique (n = 82) or to an endoscopic approach (n = 82). Endoscopic harvesting was performed with a nonsealed system. The primary endpoint was cardiac-related mortality, and secondary endpoint was survival free from major cardiac and cerebrovascular adverse events. Moreover, hand and forearm sensory discomfort and forearm wound healing were also assessed. RESULTS: No conversion to the open technique occurred in patients undergoing endoscopic harvesting. No patients in either group showed hand ischemia; wound infection occurred only in the open group (open 7.3% versus endoscopic 0%, p = 0.007). Wound healing (Hollander scale) was considerably better in the endoscopic group (open 3.3, endoscopic 4.7; p < 0.001) as well as paresthesia at the latest follow-up (open 19.5% versus endoscopic 3.6%, p < 0.001). Pain (visual analog scale score) was significantly reduced with the endoscopic technique (open 3.2, endoscopic 1.2; p = 0.003). At 5 years of follow-up, freedom from cardiac-related mortality (open 96.3% ± 2.1% versus endoscopic 98.1% ± 1.8%; p = 0.448) as well as survival free from major cardiac and cerebrovascular adverse events (open 93.9% ± 2.6% versus endoscopic 93% ± 3.4%; p = 0.996) were similar among the groups. CONCLUSIONS: Endoscopic radial artery harvesting allows for incremental benefits in the short term in terms of improved cosmesis and reduced wound and neurologic complications, without yielding detrimental effects in terms of graft-related events at 5 years of follow-up.
