Glioma surgery: From preservation of motor skills to conservation of cognitive functions.

The first step of glioma treatment is surgery. Extent of resection (EOR) improves patient survival if surgery does not negatively impair a patient's neurological status. However, how surgery affects the patient's quality of life (QOL) has been less studied, especially as regards cognitive aspects. In our study, we retrospectively analyzed our cases with awake surgery. In all patients, surgical excision was stopped when active functions were intraoperatively identified. A neuropsychological assessment was performed both before and after surgery (5 days and 1 month after). Writing, motor speech, comprehension, expression, reading, pragmatics, attention, memory, problem solving and visuoperceptive functions were evaluated and scored with the NOMS scale. We found no differences in the median values of writing and motor speech, while there was a difference in the following variables: comprehension, expression, reading, pragmatics, attention, memory, problem solving and visuoperceptive functions. Moreover, the Dunn test did not show any difference between preoperative evaluation and evaluation performed 30 days after surgery regarding comprehension, expression, reading, pragmatics, attention, problem solving and visuoperceptive functions. However, there was a difference between preoperative and postoperative evaluation for memory. This retrospective study shows that awake surgery could be a reasonable possibility to preserve a patient's QOL achieving an EOR >82% of the Total Tumor Volume (Fluid-attenuated inversion recovery (FLAIR) hyperintense region in low-grade gliomas and enhancing nodules plus FLAIR hyperintense region in high-grade gliomas). In this series memory was the only aspect that had an impairment after surgery without a complete recovery at one month after surgery.

Adaptation and validation of the Italian Pediatric Voice Handicap Index.

OBJECTIVE: To evaluate the internal consistency, reliability and clinical validity of the Italian version of the Pediatric Voice Handicap Index (pVHI). PATIENTS AND METHODS: The parents of 30 children with dysphonia and 43 asymptomatic children were included in the study. Each parent was asked to complete the Italian pVHI autonomously. The voice of each child was assessed perceptually through the GRB parameters of the GRBAS scale. Internal consistency was analyzed through Cronbach's α coefficient. For test-retest reliability analysis, the Italian pVHI was filled twice, with a 2-week interval, and the scores obtained were compared through the Pearson correlation test. Clinical validity was assessed comparing the scores obtained in the pathological and the control group using the Mann-Whitney test. Finally, the correlation between pVHI and the perceptual parameters was assessed. RESULTS: All of the parents filled in the entire questionnaire autonomously. An optimal internal consistency was found (α = 0.95); the test-retest reliability in the parents of both groups of children was high (r > 0.88). The control group scored significantly lower than the pathological group (p = 0.0001). The pVHI scores positively correlated with perceptual assessment of voice disorders. CONCLUSION: The Italian pVHI is easily administered, highly reproducible, and exhibits excellent clinical validity.
